A lower part (2) of the shell has a longitudinal slit (28) on the side opposite to the sole which extends from the tip of the shoe to the heel region. The slit is covered by a shell cover (3) arranged on the lower part (2) of the shell with which it forms a single piece and which extends from the tip (22) of the boot to the shaft (4) above the longitudinal slit (28). The shaft (4) consists of at least one front flap (5) and a rear flap (6). The flaps are secured to the shell by swivelling axes. Closure devices and adjustment devices are arranged on the individual parts or flaps of the skiboot. The shell cover (3) extends to an end of the front flap (5) opposite to the sole (25) and is encompassed in the region of the instep by a support surface (24) connected to the shaft (4). An instep cover (20) of the shell cover (3) pivots relative to a covering part (19) for the interior part of the foot which forms part of the shell cover, about an axis (21) perpendicular to a longitudinal direction (26) of the sole and approximately parallel to the sole (25).

Description

The invention relates to a ski boot with a shell and a multi-part upper with a shell lower part, which on a side facing away from the sole has a longitudinal slot extending from the area of a toe to the heel area and with one arranged on the lower part of the shell from the area of the toe to Shaft above the longitudinal slot extending in particular in one piece with the shell lower part of the shell lid at least one front flap and a tailgate which form the shaft and are attached to the shell via pivot axes and with closure devices and with adjusting devices between the individual parts or flaps of the ski shoe and with one Damping device for the template, which is arranged between the shaft and the lower shell part.

The most diverse embodiments for ski shoes have already become known, some of which are provided with a front entry, a rear entry or also with a so-called central entry. These different types of entry should on the one hand make getting in and out of the ski shoe as comfortable as possible and, on the other hand, should enable a favorable transfer of forces between the foot and the ski when the ski shoe is closed.

A known ski boot - according to FR-A 2 498 431 - has a shaft consisting of a front and a tailgate, which are pivotably mounted on the lower part of the shell via pivot axes. Between the tip of the shoe and the beginning of this facing the front flap a shell lid is arranged. This is encompassed by a locking device that is attached to the tabs on the front flap, which extend in the direction of the toe on both sides of the shell cover, is arranged. A template damping device is assigned to the tailgate of the shaft. The arrangement of the closure device on the flap of the front flap extending in the direction of the shoe tip almost eliminates the effect of the original damping device in the region of the rear flap of the upper, so that a satisfactory damping of the original movement and a tight seal between the shell cover and the front flap of the upper are not achieved can be.

Another known ski boot - according to AT-B 374 094 - consists of a shell lower part and a one-piece shaft which can be pivoted relative to this. A shell cover is arranged in the forefoot and instep area, which extends into the area of the shaft. In the instep area, that is, in the transition between the forefoot area of the shell and the shaft, the shell lid is provided as a template damping device with groove-shaped depressions extending transversely to a longitudinal extent. These lead to a weakening of the shell cover, whereby the damping characteristics can be changed with different template positions depending on the design of the grooves. Exact guidance of the shell cover with different templates cannot be achieved with this design of the shell cover, since in particular longitudinal deformations of the shell cover in the direction of the shoe tip cannot be prevented. This means that exact guidance of the foot in the ski boot cannot be achieved.

Various embodiments of such ski boots, which are to be opened in a large area to make it easier to get in and out of them, can be found in DE-OS 23 41 658, AT-PS 331 672 and DE-OS 34 29 237, among others known. A common feature of these known ski boots is that a shell cover can be pivoted relative to the sole about an axis arranged in the region of the shoe tip and extending transversely to the longitudinal direction of the sole, so that an area between a tailgate of a shaft and an instep area is exposed for easier slipping in and out. With some Versions, the shell cover can be swung forward so that the entire footbed is accessible from above. Although such a configuration of the ski shoes makes it easier to slip in and out, the movement sequence with the ski shoe closed is unsatisfactory, particularly with regard to the pivoting of the shaft relative to the shell, and it occurs especially with those ski shoes in which the shell upper part is over the entire length can be swiveled up, problems with tightness in the transition area between the lower shell part and the swiveling shell cover.

Another embodiment of ski boots is known for example from DE-AS 21 28 769, CH-PS 642 520 and from DE-OS 34 29 891. In these known ski boots, the tailgate of the shaft is designed in such a way that it can be pivoted forwards by a larger angle than the front flap. This pivoting makes it easier to get in through the larger free space in the heel area. In order to enable the tailgate to be pivoted to such a large extent, a corresponding arrangement of the pivot points is required, as a result of which the movement of the shaft during skiing can usually not be optimally adapted to the movements of the lower leg relative to the foot.

The present invention has for its object to provide a ski boot of the type mentioned, which allows easy slipping in and out, and in the closed state allows a good fixation of the foot in the shoe even at different angular positions between the foot and the lower leg. In addition, it should be possible to adapt the shoe well to the transition area between instep and shin base. If necessary, it should also be possible to move the template between the To dampen the shell and the shaft. Furthermore, it should preferably also be possible to switch off this damping device when the shaft is closed.

This object of the invention is achieved in that the shell cover extends into the area of an end of the front flap of the shaft facing away from the sole and in the instep area a support surface connected to the shaft and supporting the shell cover engages in the area of which a surface between the front and tailgate extending locking device formed by a buckle arrangement is arranged, and that an instep cover of the shell cover relative to a forefoot cover thereof about a transverse to a longitudinal direction of the sole and approximately parallel to the sole is pivoted by the locking device that the axis in the direction of Shoe tip is arranged adjacent and in particular formed by a buckle arrangement is fixed to the lower shell part.

Due to the interaction of the instep cover of the shell cover with the support surface connected to the shaft, an opposite relative movement of the instep cover and the support surface is advantageously achieved approximately perpendicular to the sole when the lower leg is pivoted forward, so that an exact guidance of the instep is obtained over the entire forward movement remains. At the same time, this embodiment of the ski boot also ensures that when the shaft or ski boot is opened, the front flap can be pivoted forwards independently of the instep cover and the movement of the instep cover in the direction of the shaft is released by pivoting away the support surface. This allows the instep cover to be pushed upwards by the foot when it slips out of the shoe, thereby allowing the foot to move as freely as possible between the instep and heel while pivoting the tailgate. By pivoting the front and rear flaps in opposite directions and the possibility of the instep cover also to move in the direction of the front flap, a so-called "central entrance" reached. Without additional mechanical means, such as cable pulls or the like, an adjustment device for heel adjustment and the instep covering can be brought into a desired position adapted to the anatomical shape of the foot when the shaft is closed and due to the support surface. It is surprising here that with such a solution the pivot axis for the shaft can be arranged approximately in the ankle region or in the region of the ankle axis, whereby the pivot region of the shaft can simply follow the natural movements of the lower leg relative to the foot. The adaptation of the instep cover to the different operating conditions such as open front flap or closed front flap is facilitated by the axis around which the instep cover is pivoted and, above all, a targeted movement path is impressed on this part, which favors this play-free guidance of the foot between heel and instep.

According to a further embodiment, it is possible for the lower shell part and the shell cover to form separate components, as a result of which the design of the pivot axis can be more easily adapted to the respective load and the desired movement sequence.

However, it is also advantageous if the forefoot cover and the instep cover of the shell cover are formed in one piece, since this can simplify the effort for the manufacture of the instep cover according to the invention.

According to another embodiment, it is possible that a line of weakness is arranged between the forefoot cover and the instep cover, which is preferably formed by a cross-sectional weakening, whereby an additional mechanical effort for the production of the axis can be saved.

It is also possible, however, that the cross-sectional weakening is formed by a groove-shaped depression in the forefoot cover which runs transversely to the longitudinal direction of the sole, the groove bottom of which has a shorter length than a width of the forefoot cover, since this causes the If suitable materials are used, this inherent elasticity can be used simultaneously for pivoting the parts to one another.

But it is also possible that a pivot arrangement is arranged between the forefoot cover and the instep cover, which has a pivot axis forming the axis, whereby the resistance to the forward pivoting of the front flap can be kept approximately the same over the entire pivoting range.

According to a variant of the embodiment, it is provided that the forefoot cover and the instep cover are pivotably mounted on the pivot axis of the pivot arrangement independently of one another, which makes it possible to arrange the bearing point of the pivot axis of the pivot arrangement directly in the individual covers.

According to another embodiment, it is provided that the swivel arrangement is arranged between the instep cover and the lower shell part, as a result of which good anchoring can be achieved without stressing the forefoot cover.

But it is also possible that the line of weakness or the axis through the closure device which is arranged immediately adjacent in the direction of the toe and is formed in particular by a buckle arrangement relative to the lower shell part, whereby a good seal between the forefoot cover and the lower shell part, and at the same time the line of weakness or the swivel axis can be fixed in the longitudinal direction. This additional support means that the instep cover does not have to transmit all the forces acting on it in the longitudinal direction of the sole and may therefore be of weaker construction.

According to a further embodiment variant, it is provided that the pivot axis forming the axis is mounted in the lower shell part, whereby good anchoring of the pivot axis is possible and relative movement of the instep cover relative to the lower shell part can take place.

Furthermore, it is also possible that the closure device e.g. the buckle arrangement is arranged in the groove-shaped depression and the line of weakness is formed by the transition between the groove bottom and a groove flank facing the instep cover. The desired movement geometry can be achieved with simple means by using an edge of the molded part directly adjacent to the closure device as a line of weakness.

However, it is also possible for the shell cover in the region of the shoe tip to be connected to the lower shell part by means of a holding device, as a result of which the assembly of the shell cover is facilitated.

Also advantageous is an embodiment according to which the holding device is arranged in a fixed manner on the lower shell part in the longitudinal direction of the sole, since the instep cover can be supported in the longitudinal direction of the sole over the shell cover by such an embodiment.

According to another embodiment, it is provided that the shell lid can be pivoted in the area of the holding device about an axis running approximately parallel to the axis, which makes it easier to remove the inner shoe and also to slip it in and out of the ski shoe.

However, it is also advantageous if the instep cover is preferably guided between the axle and the heel area in a slide track which is arranged in the lower shell part, since the additional guidance of the instep cover in the slide track reduces the load on the weakening line and the desired one even under heavy loads Sequence of movements of the instep cover can be maintained.

However, it is also possible for the backdrop path to pass through in the area Longitudinal slots arranged by two side walls of the lower shell part are formed, which are inclined relative to one perpendicular to the sole by a small angle between 5 ° and 30 °, preferably 15 °, in the direction of the shoe tip. As a result, the end of the instep cover facing away from the line of weakness or axis can be moved in a direction corresponding to the desired movement sequence when loaded by the instep or the shin attachment and, especially under load, cannot deflect laterally or in the undesired direction.

Furthermore, it is also possible for the slide tracks to be designed in the form of a circular arc and the center of which forms the axis, as a result of which strains in the instep cover and thus excessive stresses in the axis can be avoided.

According to another embodiment, it is provided that the slide track is designed in the form of a circular arc and that its center is in the area of the holding device of the shell cover, so that the shell cover is not additionally burdened, particularly when it slips in and out of the ski boot.

However, an embodiment variant according to which the slide track has two circular-arc-shaped sections with different radii is also advantageous, since this allows the instep cover to move with the ski shoe closed, with reference to the line of weakness or axis, while opening the shaft or the ski shoe to remove it - or slip in, the further movement of the instep plate can take place with reference to the further hinge point, for example, the shell lid.

According to another variant, it is also possible that a width of the slide track is greater than a diameter or a width of guide members guided in it, since this compensates for the movement at different pivot radii of the instep plate by the difference in dimensions between the guide members and Scenic tracks can be done.

According to another embodiment of the invention, it is provided that the front and rear flaps are preferably mounted on the two side walls of the lower shell part for both common pivot axes, whereby a movement of the shaft part which is adapted to the movement of the lower leg relative to the foot can advantageously be achieved.

It is advantageous if the front flap is approximately semi-cylindrical and has a U-shaped cutout extending centrally from the lower front end towards the upper front end, since this results in a correspondingly high degree of mobility of the front flap relative to the shell or the Shell cover becomes possible.

According to a further preferred embodiment, it is provided that a slot which extends in the direction of the upper end end and in particular tapers is arranged on the U-shaped cutout and ends at a distance below the upper end end. This solution allows a greater free space for closing the shaft, so that it can be better adapted to the different anatomical course of the foot in the lower leg area immediately following the foot.

It is also advantageous if a base of the U-shaped cutout forms the support surface, since when the ski boot is closed, the shaft part, that is to say the front flap, can also be used to support and guide the instep plate.

Furthermore, it is also possible for the front flap to support a support plate, the front edge of which faces the lower end face forms the support surface, as a result of which the front flap does not have to be made so massive and additional shin protection is provided by using a support plate.

But it is also possible that the front flap consists of two front flap parts, each of which on one of the two in the other Opposed side walls arranged pivot axes is mounted, as this makes it even easier to adapt to different lower leg diameters.

It is advantageous here if the front flap parts are connected to one another via the support plate, since the necessary strength of the front flap can be achieved by using the support plate.

However, a design is also possible in which the support plate is adjustable in the circumferential direction of the front flap or the front flap parts at least along a part of guide arrangements extending on both sides of the cutout and / or the slot relative to the front flap or the front flap parts, as a result of which in A stepless adjustment of the shaft width to different lower leg dimensions is possible in a certain area.

Furthermore, it is also possible that closure devices formed by buckle arrangements are provided between the front flap or the front flap parts and the tailgate, and that a buckle arrangement supports the support surface, the support surface preferably being arranged on a support plate connected to the buckle arrangement, since as a result the position the support plate can also be adapted exactly to the setting of the shaft defined by the buckle arrangement.

It is also advantageous if the buckle arrangement is anchored in the tailgate and preferably passes through it, since this ensures good anchoring and guidance of the buckle arrangement in the region of the tailgate.

It is also advantageous if the buckle arrangement has a notch strap, which is connected via an eccentric buckle with an actuating lever and a carrying strap to the tailgate, and a locking member is assigned to the notching strap, which in turn is anchored in the tailgate by means of a strap, as a result of which a sensitive adjustment of the tension forces acting on the foot or the closing forces to adapt the shaft to the shape of the lower leg is possible.

According to a further embodiment variant, it is provided that the carrying strap for the locking member and the detent strap is in one piece, so that it can be found with a fastening point for the carrying strap, preferably in the region of the tailgate.

However, it is also possible that the support band in the region of the two side walls of the tailgate are assigned holding members and that the holding members are preferably adjustable in the direction of the longitudinal axis of the sole, whereby a central alignment of the buckle and thus a central tension of the shaft is achieved.

According to another embodiment variant, it is provided that the carrying strap penetrates the side wall of the tailgate in the area of the holding members and the holding members are connected to an adjusting device which can be adjusted in the longitudinal direction of the sole, whereby centering of the buckle arrangement is additionally possible.

However, it is also possible for the holding member to be provided with a locking member for the carrying strap, which creates the prerequisite that a part of the carrying strap extending into the interior of the ski boot can be used for further functions.

According to another embodiment, it is provided that a support tab for the heel is arranged on the supporting band section running between the two holding members in the interior of the shaft, whereby the supporting band can not only be used for the buckle arrangement but also for heel support and with a suitable design when released the buckle arrangement and thereby the heel support is released when the front and rear flaps are opened, thereby creating an even greater free space for slipping in and out of the ski boot.

According to another further development it is provided that the buckle arrangement comprises an eccentric buckle with catch straps arranged at both ends and that locking members are assigned to each other in the region of the tailgate, the eccentric buckle and / or the catch straps being fastened in an adjustable manner in relation to the front flap, whereby the eccentric buckle can always be locked in the middle.

It is advantageous here if the two locking members are arranged, in particular, sunk in the side walls of the tailgate, since jamming in the area of the locking members is avoided.

However, it is also possible that the front flap and the tailgate are connected to the side walls of the lower shell part via separate pivot axes, whereby the opening width of the front and tail flap can be increased further in accordance with the arrangement of the two pivot axes separated from one another.

However, it is also advantageous if the tailgate is mounted on the front flap supported on the lower part of the shell by means of pivot axes, since in this embodiment a uniform pivot axis can be achieved in the closed state, for example in the region of the ankle pivot axis, whereas when the ski boot is opened, one versus one Arrangement of the front and tailgate on a common axis larger opening width and thus a more comfortable in and out slipping is possible.

Another embodiment provides that the shaft is connected to an adjusting device for the template or template damping, which is arranged between the front flap and / or the tailgate and the lower shell part, and which has a damping device formed, for example, by a spring, whereby after a corresponding damping of the template is possible after closing the shaft.

Furthermore, it is advantageous if the front and / or tailgate is guided in a guide device of the adjusting device so as to be adjustable relative to the latter and that a releasable coupling device is arranged between the front and / or or the tailgate and the adjusting device. By switching off the function of the damping device via the releasable coupling device as required, the movement of the front or tailgate when the ski boot is open is not hindered by this damping device and a pre-positioning of this part can take place in the closed state, while in the open state the free part remains There is mobility and thus it is easier to slip out and in.

According to another embodiment variant, it is provided that the adjusting device for adjusting the template and / or template damping of the shaft is arranged in the instep area between the lower shell part and the front flap, whereby simpler operation is achieved with less stress on the buckle arrangements connecting the front flap to the tailgate becomes.

Furthermore, it is also possible for a spring element to be arranged as a damping device in the overlap region of the front flap and the lower shell part, which extends from a region of a side wall closest to the sole over the shell cover into the region of the opposite side wall in the region of the sole and in the region of its base. "The ends facing the sole are held in a holding device. The advantage of this solution is that such a spring element is built very low and thus an optically advantageous shape of a ski boot can be achieved and at the same time the advantages of a damping device arranged in this way can be achieved with simple operation .

However, it is also advantageous if the holding device has a bore penetrating the lower shell part approximately parallel to the sole, into which legs of the spring element running approximately parallel to the sole engage and the holding device further unites between the bore and the shell cover comprises an abutment arranged on the lower shell between the spring element and a toe and the spring element is fastened in a guide plate which forms a guide device with guide slots in the housing of the adjusting device, the guide slots of the housing on the side of the shell facing the Front flap are arranged and the locking pin of the coupling device penetrates the front flap and the eccentric lever is arranged on the side of the front flap facing away from the lower shell part, since this enables the spring element to be held securely and also to absorb large damping forces. Nevertheless, the size and the number of openings in the area of the front flap are kept small, so that despite the various adjustment and adjustment options, a high level of tightness of the shoe is achieved.

However, it is also possible for the locking pin to be assigned a bore in the guide plate, as a result of which a simple connection can be established between the front flap and the lower shell part, which also enables the adjustment movements to be damped to be transmitted without play.

According to another development, it is provided that the abutment has a height which is greater than a distance between the mutually facing surfaces of the lower shell part and the shell cover and the abutment formed with a round or polygonal cross section is guided in a groove of the front flap facing the lower shell part is, wherein the groove is arranged on a connecting line between the toe and the tailgate, whereby the part required as an abutment for the spring element can also be used to limit the maximum displacement of the front flap relative to the lower shell part. This makes it possible to find sufficiency with a smaller number of individual parts, as a result of which the assembly costs are not disadvantageously changed when using such an adjustment device.

It is also advantageous if the abutment for the spring element on an actuator e.g. an adjusting strip of an adjusting device is arranged, as a result of which the suspension characteristics during template movements can easily be adapted to different conditions, for example in deep snow or hard slopes.

A lower overall height of the adjusting device is further achieved if the actuator is formed by an expansion-resistant but flexible adjustment strip perpendicular to the surface of the lower part of the shaft, which is arranged in a longitudinal slot in the lower part of the shell in a plane inclined with respect to the shoe axis via a pin preferably formed by the abutment is, nevertheless high support forces can be absorbed by the abutment, since it can be supported by the pin in a longitudinal slot in the lower part of the shell.

According to a further embodiment it is provided that the actuator is coupled to an adjustment drive of the adjustment device, whereby a quick adjustment of the actuator can be achieved.

It is also advantageous if the adjustment drive is provided by a threaded spindle with two opposing threaded sections, which is mounted in the front flap and is coupled to an actuating element arranged outside the front flap, which actuates from an actuating position projecting relative to the front flap into an abutting position on the front flap if necessary, can be pivoted in this retracted rest position, since a change in the damping characteristic or spring characteristic of the spring element can be achieved without manipulation of the front flap and in any position of the front flap relative to the lower shell part.

In addition, it is advantageous if the actuating member has different actuating positions with respect to the front flap, since this allows the actuating member to be locked in a simple manner, so that a preselected setting is also possible during the use of the ski boot, i.e. the skiing maintains its attitude.

However, it is also possible for the actuating member to form the eccentric lever of the coupling device and for the locking pin to be displaceably mounted on the threaded spindle in the longitudinal direction thereof and to be provided with an annular groove facing the threaded sleeve, into which guide pin e.g. Thrust pins engage, which is connected to the inside of the threaded sleeve in the longitudinally displaceable push rod which is rotatably mounted on its other end on the eccentric lever, which makes it possible to change both the suspension and damping characteristics with a single common actuating member also to enable locking and unlocking between the spring element and the front flap.

Another development provides that the spring element is connected to a coupling part, in which the bore for the locking pin is arranged, the bore being penetrated by the threaded spindle of the adjusting device. As a result, large forces can be transferred from the locking pin to the spring element, and it can still be found with a low overall height.

Finally, it is also possible for the spring element to be U-shaped or C-shaped and for one leg to be connected to the guide plate and another leg or a base of the C-shaped spring element to the lower shell part, which also means that the height is different having spring elements can be used in connection with the adjusting device.

For a better understanding of the invention, it is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

1 shows a ski boot 1 designed according to the invention, the shell of which consists of a lower shell part 2 and a shell cover 3. A shaft 4 consists of a front flap 5 and a rear flap 6. The front flap 5 is pivotably supported by pivot axes 8 supported in side walls 7 of the lower shell part 2. The tailgate 6 is connected in an articulated manner to the lower shell part 2 via its own pivot axes 9 also mounted in the side walls 7 of the lower shell part 2.

Closure devices are arranged to close the shaft 4 or the lower shell part 2. The closure devices consist of buckle arrangements 10, 11. Each buckle arrangement 10, 11 comprises an actuating lever 12 which can be pivoted about an axis 13. The actuating lever 12 of the buckle arrangement 10 is further coupled with a catch 14, which in turn interacts with a ratchet part 15 by means of drivers, for example an opposing toothing. The ratchet part 15 is connected to cables 16, which are guided in brackets formed by receiving openings 17 on the front flap 5 and are anchored in the tailgate 6. By adjusting the actuating lever 12 from the drawn in full lines from the front flap 5 to projecting position into a position against the front flap 5, the cables 16 are tensioned, whereby the front flap 5 and the tailgate 6 are locked in a closed position. An adjusting device 18 for the template is connected to the tailgate 6.

As can also be seen from this illustration, the shell cover 3 consists of a forefoot cover 19 and an instep cover 20. The forefoot and instep cover 19, 20 can be pivoted relative to one another about an axis 21 which runs approximately parallel to the swivel axes 8, 9. For this purpose, the forefoot and instep cover 19, 20 are mounted in a swivel arrangement which has a swivel axis forming the axis 21. This can be supported in the lower shell part 2 or only connect the forefoot to the instep cover 19, 20. As indicated by dashed lines, the instep cover 20 extends into the area above the shin base at the foot in order to allow the foot to be firmly seated in the ski boot.

In order to prevent the instep cover 20 from evading in the direction of a toe tip 22 when the instep is pressed strongly, a base of a U-shaped cutout 23 arranged in the front flap 5 is designed as a support surface 24.

If the shaft 4 closed by the buckle arrangement 10 is moved forward by a relative movement of the lower leg in the direction of the foot, for example when a skier goes to his knees, the pressure of the instep of the wearer of the ski shoe increases on the instep cover 20. This tries now dodge towards the toe 22. Excessive deformation of this instep cover 20 in the direction of the shoe tip 22 is now counteracted by the support surface 24 which overlaps the instep cover 20. The swivel path of the instep cover 20 is designed such that it becomes larger with increasing presentation and increasing forward movement of the front flap 5. With a corresponding design of the U-shaped cutout 23 in the region of the front flap 5 it can further be achieved that when the front flap 5 is pivoted forward with the buckle arrangement 10 open, the base of the U-shaped cutout 23 can be pivoted forward into the region of the axis 21 . The axis 21 runs parallel to a sole 25 and transversely to a longitudinal direction 26 of the sole, which is represented schematically by an axis extending from the tip of the shoe 22 into a heel region 27.

As further indicated by dashed lines, the shell cover 3 extends along and above a longitudinal slot 28 of the shell lower part 2, which runs between a shoe tip 22 and the heel area 27.

To hold a leg 29, indicated schematically by thin lines, free of pressure, an inner shoe 30 made of soft material, for example an open-cell PU foam with textile or leather lining, is arranged on the inside or outside between the leg 29 and the shell and the shaft 4.

Another advantage of the illustrated ski boot 1 is that after opening the buckle arrangement 10, the front flap 5 of the shaft 4 can be moved forwards about the pivot axes 8 in the direction of the front buckle arrangement 11 or the toe 22, depending on the arrangement of the pivot axes 8, the support surface 24 allows the front flap 5 to pivot into the area between the axis 21 and the toe 22. This allows the instep cover 20 to move almost freely about the axis 21, so that when the leg 29 slips out of the ski boot 1, the instep cover 20 can be pivoted away from the instep area in the direction of the toe 22. As a result, the tension which is important in a ski boot between the instep area and the heel area can be removed, so that it is easier to slip in and out. In addition, the tailgate 6 can be pivoted about the pivot axes 9 - as also indicated by schematic lines - to the rear, which also releases the heel fixation and makes it even easier to slip in and out. The front flap 5 and the tailgate 6 are therefore adjustable in the manner of a central lock in the opposite direction in the longitudinal direction 26 of the sole, so that the greatest possible distance between the instep area and the heel area is achieved. In the case of the leg 29 in the ski boot, on the other hand, the opposing closing of the front and tailgate 5 and 6, respectively, adapts the heel to the heel area and the instep cover 20 via the support surface 24 into the desired area which locks this area of the foot Position pivoted. A ski boot 1 designed in this way thus enables central release of the slip-in area without complex cable pull mechanism between the individual parts of the front flap 5 and the tailgate 6 and a firm mounting and fixing of the leg 29 in the ski boot 1.

Another embodiment variant of a ski boot 1 is shown in FIG. This also comprises a lower shell part 2, a shaft 4 formed from a front flap 5 and a rear flap 6 and an inner shoe 30 arranged in the interior of the lower shell part 2 or the shaft 4. The lower shell part 2 is again provided with a longitudinal slot 28 which extends from the Shoe tip 22 extends into the heel area 27. This longitudinal slot 28 is closed by a shell cover 3 which extends above the longitudinal slot 28. The shell cover 3 consists of a forefoot cover 19 which extends from the area of the toe 22 to an imaginary axis 21. An instep cover 20 connects from there. The axis 21 is formed by a weakening line running transversely to the longitudinal direction 26 of the sole and parallel to the sole 25. This line of weakness arises from the fact that a cross section of the shell cover 3 between the forefoot cover 19 and the instep cover 20 is reduced. For this purpose, the shell cover 3 is provided with a groove-shaped recess 31 in the forefoot cover 19. A groove bottom 32 of the recess 31 has a shorter length 33 than a width 34 of the forefoot cover 19 that is directly adjacent to it. In addition, a buckle arrangement 11 is provided in the area of this groove-shaped recess 31, with which the groove bottom 32 fixes its position in relation to the lower shell part 2 can be. In the present case, a line of weakness 35 is formed through the transition region or the edge between the groove bottom 32 and a groove flank 36. The instep cover 20 can thus be pivoted about this weakening line 35 in the longitudinal direction 26 of the sole. In order to ensure pivoting in the desired direction, the instep cover 20 is also connected to guide elements 37 which are guided in the side walls 7 of the lower shell part 2 and are arranged in an adjustable manner approximately perpendicular to the sole 25. In connection with the design of the slide track 38 and in cooperation with the weakening line 35, the instep cover 20 can now be pivoted approximately in a circular path about the axis 21.

The movement of the instep cover 20 is limited by the support surface 24, which is arranged on a support plate 39, which in turn is attached to the front flap 5.

The support plate 39 can now be selected in accordance with the stresses of the material rigidity, the thickness and the shape, since elastic properties such as are required, for example, in the pivotable front flap 5 are not required. For example, this support plate 39 can be solid, particularly in the area of the support surface 24, so that the instep cover 20 cannot deflect in the direction of the shoe tip 22 even under heavy loads. However, it is advantageous here if the support plate 39 is simultaneously used to distribute the clamping forces of the buckle arrangements 10 in the region of the shaft 4. In order to divide the clamping force of the buckle assemblies 10 into the desired areas, the support plate 39 with guide ribs 40, 41 can serve to guide carrying straps 43, 44 receiving the actuating lever 12 or a locking member 42 or a detent band 45 connected to the actuating lever 12. Due to the rigid design of the support plate 39 and a corresponding design of the U-shaped cutout 23 and a slot 47 extending, in particular V-shaped, tapering in the direction of an upper end 46, this support plate 39 can be any inclined position relative to the lower leg in adaptation to the Take the course of the lower leg.

3 to 5, which show different views of the same ski boot 1 as in FIG. 2, the adjustment of the shaft width in the area of the foot drawn in thin dash-dotted lines in all the figures can be seen better. In the instep area of the foot, two different anatomical options are purely schematic and in some cases strong for better understanding of the proportions exaggerated with dash-dotted lines and dashed lines. A foot shape corresponding to the dash-dotted line corresponds to a position of the support plate 39 as shown in full lines. During the formation of a foot corresponding to the dashed line with a high instep and a relatively straight attachment of the shin corresponds to the position of the support plate 39 shown with dashed lines. As can also be seen from this illustration in FIG. 3, both the support plate 39 has a compensating effect and also the instep cover 20, since this increases the instep of the leg 29, for example by bending around the weakening line 35 instead of the one drawn in full lines Position which corresponds to a dash-dotted course of the leg 29 which assumes the position indicated by dashed lines. The fixation of this weakening line 35 in the direction of the shoe tip 22 and the height-based guidance in the lower shell part 2 along the slide path 38 makes it possible to adapt the position of the instep cover 20 to the instep course or the transition between instep and shin on the respective leg 29.

This adaptation is not least facilitated by the fact that the support plate 39, as can be seen better in FIGS. 4 and 5, is supported in the upper end of the V-shaped slot 47 by a pin 48 in the direction of the upper end 46. Furthermore, the support plate 39 is slidably mounted on guide pins 49, 50 in the region of guide arrangements 51 extending on both sides of the U-shaped cutout and / or the V-shaped slot 47. As a comparison of the two representations in FIGS. 4 and 5 shows, a cross section of the shaft 4 can be achieved by changing the circumferential length of the front flap 5. For example, by tightening the buckle assembly 10 closer to the sole 25, a cross-sectional width 52 in which the guide pins 49 and 50 are located approximately in the middle of the guide assemblies 51 can be reduced to a cross-sectional width 53 as shown in full lines in FIG the guide pins 49, 50 are then located in the end regions of the guide arrangements 51 which are spaced apart from one another. By using the guide pin 49, 50 and the pin 48, which supports this support plate in the direction of the upper front end 46 of the front flap 5, the adjustment can take place according to a predeterminable spatial guideway. This prevents undesirable tension or deformation of the front flap 5. The reduction of the cross-sectional width 52 to the cross-sectional width 53 is made possible by bringing the two flanks of the V-shaped slot 47 into a position parallel to one another, as can be seen from FIG. Due to the fixed cross-sectional width 52 in the area of the upper end 46, the deformation occurs only in the area closer to the transition area between the shin and instep, in which experience has shown that, for anatomical reasons, people have different or strongly changing foot cross-sections. The advantage of this solution is that a smaller cross-sectional width 53 in the area of the buckle arrangement 10 closer to the support surface 24 almost does not increase the tension in the area of the buckle assembly 10 closer to the upper front end 46. In the ski boots used hitherto, the lack of flexibility of the front flap 5 in the circumferential direction leads to an inaccurate adaptation of the ski boot to the transition area between instep and shin attachment, causing the skier to press against the upper front end 46 of the front flap 5 when the skier goes to his knees or there are higher surface pressures than desired and this pressure is perceived as unpleasant or often leads to an overload of the skin surface (pressure points, blistering). In this respect, in addition to its support function with the support surface 24, this support plate 39 also has a function that transmits the clamping forces over a large area to the shin area, which is achieved by a correspondingly coordinated design of the support plate 39 and the front flap 5. Further advantages of this design result from the interaction of the support surface 24 with the instep cover 20 by the pivoting of the instep cover 20 about the axis 21 shown in FIG. 4 or the weakening line 35 in the edge region of the depression 31. This is because the lower leg of the leg 29 becomes in In the direction of an arrow 54 pivoted forward about the ankle joint, for example when the skier kneels, there is automatically relief in the heel region 27, ie the heel has a tendency to lift off the sole 25, as a result of which the instep cover 20 is subjected to greater stress by the instep of the leg 29. Under load, the instep cover 20 now tries to move in the direction of the support plate 39, but is retained by the support plate 39 to an extent corresponding to the forward pivoting of the front flap 5 over the support surface 24. This prevents the leg 29 or the heel from lifting too far from the sole 25, or from the adjustment device 55 indicated by dashed lines for holding or adapting the heel or in the region of the archilles tendon, and thereby the lateral guidance of the leg 29 is lost compared to ski boot 1. A loss of this fixation leads to the fact that the rotational movements of the leg 29, for example when swinging, can no longer be transmitted to the ski to the necessary extent, from which the guidance of the ski suffers. Due to the increased resistance which is opposed to deformation of this instep cover 20 via the support plate 39 and the support surface 24, the transmission of the rotational movement of the leg 29 to the ski is favored. It is also important here that the instep cover 20 is fixed in the longitudinal direction - arrow 57 - of the ski boot 1 via the forefoot cover 19 and a holding device 56.

As shown in FIGS. 2 to 4, this holding device 56 consists of a tab 58 formed on the lower shell part 2 and provided with a locking lug 59 at its end facing the heel area 27. This can also be integrally formed on the tab 58. A bracket 60 of the holding device 56 is supported on the tab 58, which prevents further slipping in the direction of the shoe tip 22. The locking lug 59 prevents the forefoot cover 19 from being pulled out or pulled from the lower shell part 2. However, this holding device 56 is flexible for pivoting perpendicular to the sole 25. When the buckle arrangements 11 are open, the forefoot cover 19 can be pivoted up with the instep cover 20 for better access and for easier slipping in and out. When slipping in and out, the full length of the slide track 38 in the lower shell part 2 can be used be when the guide member 37 which is connected to the instep cover 20 is adjusted in the upper region of the slide track 38. As a result of this mobility in the holding device 56, the entire articulation for utilizing the full adjustment path in the link path 38 through the weakening line 35 or in the region of the axis 21 does not have to be applied, but it can be done especially when the ski boot is opened when the buckle arrangements 11 are open Part of the pivoting movement of the shell cover 3 takes place via the holding device 56, as will be explained in more detail with reference to FIG. 9.

From the illustration in FIG. 4, it can also be seen that, in order to stiffen the forefoot cover 19 between the depressions 31 for the buckle arrangements 11, the raised areas can be reinforced by internal ribs 61.

The end of the instep cover 20 facing the upper front end 46 is provided with V-shaped slots 62, so that when the front flap 5 is deformed when the cross-sectional width 52 or 53 is narrowed, it can adapt to different cross-sections without causing wrinkles or the application of punctual pressure forces in the area of the shin.

The arrangement of the front flap 5 and the rear flap 6 on pivot axes 63, 64 is also shown from the lower part of FIG. The pivot axis 63 is fastened in the side wall 7 and the pivot axis 64 in a side wall 65 of the lower shell part 2. The pivot axis 64 is formed by an outer retaining washer 66 and an inner anchoring washer 67. The retaining washer 66 is provided with a through hole and the anchoring washer 67 with an internal thread. A screw 68 is inserted into the through hole, which screw is screwed into the internal thread of the anchoring washer 67 and braces the retaining washer and the anchoring washer 67 against one another. Because the retaining washer 66 and the anchoring washer 67 abut against one another with their end faces, the screw 68 can be tightened as much as desired, but remains sufficient space for the pivoting of the front flap 5 and the tailgate 6 relative to the lower shell part 2.

The pivot axis 63 is formed opposite to the canting adjustment of the shaft 4 relative to the lower shell part 2 or the sole 25. This canting setting with which a shaft axis 69 can be adapted to the anatomical conditions of a leg 29 is achieved in that a distance 70 between the pivot axis 63 and the upper front end 46 is changed in the region of the side wall 7. As a result, the shaft axis 69 can be pivoted by an angle either in the direction of the side wall 7 or in the direction of the side wall 65, as indicated by dash-dotted lines in FIG. This makes it easy to adapt the geometry of the ski boot 1 to 0 or X legs. For this purpose, a holding disk 71 is provided with an elongated hole 72 in which the screw 68 is guided. An anchoring washer 73, which is provided with an internal thread similar to the design of the anchoring washer 67, has a pin 74 projecting in the direction of the holding washer 71, on which a clamping plate 75, which is provided with teeth 76 on its end facing the front flap 5, is guided.

The teeth 76 of the clamping plate 75 are assigned a guide slot 77 for the clamping plate 75 in the surface of the front flap 5 facing them, the surface of which is also provided with teeth 76.

The adjustment of the shaft 4 relative to the lower shell part 2 with an adjusting device 78 for the lateral inclination of the shaft 4 consisting of the aforementioned parts is now carried out as follows: The screw 68 is screwed out of the anchoring disk 73 so far that the teeth 76 of the clamping plate 75 and the front flap 5 disengaged. The front flap 5 can then be adjusted together with the holding disk 71 mounted in a recess 79 in the same in the direction of the lower shell part 2 or in the direction of the upper front end 46. Is the desired angle of the anatomical If the situation of the foot corresponds best, the desired position can be fixed by tightening the screw 68 and tightening the teeth 76 against each other. For simultaneous adjustment of the tailgate 6 together with the front flap 5, a guide bore 80 is arranged in the tailgate 6, which is rotatably mounted on an annular shoulder 81 of the front flap 5. As a result, when the front flap 5 is adjusted relative to the screw 68, the rear flap 6 is also carried along accordingly, so that canting between these two flaps is avoided.

Of course, the retaining disk 66 can also be guided in a recess 79, so that protruding parts over the surface of the front flap 5 are avoided. Likewise, the tailgate 6 can also be guided in the front tailgate 5 in the region of the pivot axis 64, in that the tailgate 6 is provided with a guide web 82 which extends over a circular section and to which a circular opposite 83 of the tailgate 6 is assigned. In addition, a stop 84 is formed on the front flap 5, which is guided in a slot 85 in the tailgate 6. A maximum relative movement of the front flap 5 and the rear flap 6 with respect to one another is limited by this slot 85. The arrangement of the slot 85 and of the stop 84 associated with it can also be seen from FIG.

4 also shows that the instep cover 20 can be provided with reinforcing ribs 86 which are adjacent to the weakening line 35, so that the pivoting of the instep cover 20 with respect to the forefoot cover 19 actually only in the area of the weakening line and not in the immediate neighboring areas.

Openings 87 are also provided in the tailgate 6, in which a carrying strap 43, which can be connected to an actuating lever 12 or a catch strap 45, penetrates the tailgate 6. As in the area of the support band 43 closer to the sole 25 is shown, this can be fixed against a relative movement relative to the tailgate 6 by means of a fixing pin 88.

Of course, it is also possible to attach this fixing pin 88 not visible from the outside but in the interior of the tailgate 6, this fixation being particularly important when the carrying strap 43 runs through the tailgate 6 and in the area of, as shown for example in FIG opposite side wall with a locking band or a locking member 42 is connected.

Different positions of the shaft 4 relative to the lower shell part 2 are shown in FIGS. In this different position it is assumed that the setting device 18 for the template is set to its maximum range of movement, so that the entire pivoting path of the shaft 4 in relation to the lower shell part can be used. It should be noted that the design of the ski boot in FIGS. 6 to 8 corresponds to that described in detail in FIGS. 2 to 5. Furthermore, the buckle arrangements 10 have been omitted and the front flap 5 has been partially torn open in order to better represent the different relative positions between the instep cover 20, the support plate 39 and the lower shell part 2. It is assumed that the buckle assemblies 10 are closed and tightened during these movements.

6 shows the shaft 4 in its rear end position, in which a lower leg 89 has only a small template compared to a foot 90. In this position, the guide member 37 is located in the area of the sliding track 38 closest to the sole 25, since the instep cover 20 is pushed back and held in this position via the support surface 24 of the support plate 39, which means that the leg 29 and / or the transition area between the lower leg 89 and foot 90 is given. If the template of the lower leg 89 is now reinforced as shown in FIG. 7, the pressure of the lower leg 89 on the front flap 5 increases, as a result of which the shaft 4 pivots and the support plate 39 shifts in the direction of the toe 22. This also gives the instep cover 20 the ability to yield under the pressure in the instep area or in the transition area between the foot 90 and the lower leg 89.

The ski boot is shown in FIG. 7 when the leg 29 is placed more strongly than in FIG. 7. The guide member 37 is located in the sliding track 38 in a position remote from the sole 2. Due to the effect of the support surface 24, however, the instep cover 20 is only granted as much clearance as is absolutely necessary for the prevention of the lower leg 89 relative to the foot 90. Although the movement of the lower leg 89 can take place, at the same time the foot 90 cannot move forward in the instep area to such an extent that, for example, the heel 91 lifts off the sole 2, or can escape from an adjusting device 55 for holding the heel 91 in the region of the Achilles tendon can. The release of the movement of the instep cover 20 to the anatomically necessary extent by the support surface 24 shifting in accordance with the forward inclination of the lower leg 89 thus also allows the foot 90 to be properly clamped in the lower shell part 2 up to the extreme presentation, as shown in FIG In this situation as well, a flawless transmission of the rotational movement of the leg 29 to a ski connected to the ski boot 1 is possible.

8 shows an extreme template position of the lower leg 89 of the leg 29. As can be seen, the support plate 39 and the instep cover 20 are shifted extremely forward, whereby, like the dash-dotted line that shows the leg 29 in the instep area, there is still sufficient guidance and stabilization of the instep cover 20 even with the extreme presentation by the support surface 24. The instep cover 20 is located in its uppermost position furthest from the sole 25 of the ski boot, as can be seen from the sliding track 38 and the guide member 37. Due to the spatially defined displacement of the instep cover 20 due to the guidance of the guide member 37 in the slide track 38 in cooperation with the weakening line 35 can with increasing presentation of the lower leg 69, the instep cover 20 is shifted in the direction of the upper front end 46 of the front flap 5, as can be seen from a comparison of FIGS. 6 to 8. This prevents the instep plate 20 from kinking inside the shoe, that is to say in the area of the support surface 24, which would produce an undesirable pressure point on the leg 29 or in the instep area.

9 shows the ski boot 1 according to FIGS. 2 to 8 in the open position. The buckle assemblies 10, of which the carrying strap 43 as well as the detent strap 45 and the actuating lever 12 can be seen, are open and the front flap 5 and the tailgate 6 are pivoted into their maximum end position both in the direction of the shoe tip 22 and in the direction of the heel region 27 . Leg 29 is shown in a position in which it must pass the narrowest cross section between instep cover 20 and heel adjustment device 55. It proves to be advantageous that the central opening - the front flap 5 and the tailgate 6 can be pivoted about the same amount in the direction of the toe 22 and the heel area 27 - the support plate 39 the movement of the instep cover in the area of Line of weakness 35 releases, so that the force exerted on the instep cover 20 via the instep of the foot adjusts the top of the sliding track 38 up to the stop of the guide member 37 which is the most distant from the shoe sole 25. The instep cover 20 is unlocked when the front flap 5 is opened by simultaneously pivoting away the support plate 39 so that the support surface 24 is disengaged. Likewise, the adjusting device 55 is brought into its farthest position from the instep cover 20 by pivoting the tailgate 6 backwards. As can be seen, in order to bring about this release of the instep cover 20 and the release of the adjusting device 55, there are no additional mechanical parts. Cable pulls or the like. Required, but this release is mandatory by the arrangement and assignment of the individual parts of the ski boot in the aforementioned sensible manner.

The arrangement of the pivot axes 63, 64 in the region of the ankle axis proves to be very advantageous, since the shaft 4 can be opened centrally from this region. On the other hand, it can be seen from the representations in FIGS. 6 to 8 that this matching of the position of the ankle axis with the pivot axes 63, 64 results in a movement of the shaft 4 that is most anatomically adapted to the movement of the lower leg 89 and thus the friction forces and resistances that occur can be reduced in the shoe against the pivoting of the shaft 4. As further shown in this figure, the adjusting device 18 for fixing the template of the shaft 4 in its open position is also shown, for which purpose a locking lever 92 is pivoted into an open position. The function of this setting device will be explained in more detail below with reference to FIG. 10.

An advantage of this embodiment of the ski boot according to the invention is, however, that the assignment of the support surface 24 surrounds the instep cover 20 so that it can be made relatively flexible, soft and elastic in its area adjoining the line of weakness 35. The adjustment along the desired spatial adjustment path is nevertheless precisely defined by the line of weakness 35, the guide members 37 and the support surface 24. At the same time, the support surface 24, in cooperation with the instep cover 20, forms a tight seal between these parts over the entire range of motion when the shaft 4 is closed, so that no snow or the like can penetrate into the interior of the ski boot 1 in this area.

This resilience and elasticity has the further advantage that the instep cover 20, even when the guide members 37 are at the end of the slide track 38, still has a certain resilience due to the inherent elasticity, especially when the leg 29 is slipped in and out.

In order to achieve a movement path corresponding to the different movement states of the instep covers 20, it is as for example in deviation from the guideways 38 in FIGS. 2 to 8 in FIG. 9, it is shown that this guideway can be curved according to different radii, a section 93 being curved in a radius 94, the center of which forms the weakening line 35. A section 95 adjoining it is curved according to a radius 96, which corresponds to a distance between the guide track 38 and an axis 97 about which the forefoot cover 19 or the shell cover 3 can be pivoted. This axis 97 forms the holding device 56 for the shell cover 3 with respect to the lower shell part 2. As a result, when the support plate 39 swings forward a great deal and the clearance thus obtained between the support surface 24 and the instep cover 20, the instep cover 20 in the area of the weakening line 35 becomes the maximum extent deformed and as long as the guide member 37 moves in section 93, and then the entire shell cover 3 is lifted up about the axis 97, the instep cover is guided in section 95.

It should also be noted that, as shown, for example, in the illustration in FIG. 6, an angle 98 between a perpendicular to the sole 25 99 and a central axis 100 of the sliding track 38 includes a small angle, for example preferably between 5 ° and 35 °, in particular 15 °. This angle 98 is achieved with the shaft located in the rear end position, with the buckle arrangements 10 closed, in which case the guide member 37 mostly abuts the end region of the sliding track 38 closest to the sole 25.

10 shows the setting device 101 for setting the template of the shaft 4, of which only the tailgate 6 can be seen on a larger scale. This adjustment device 101 is intended to hold the leg 29 in the heel area 27, so that the leg is clamped between the heel area 27 and the instep. This clamping is intended to ensure that rotational movements of the leg 29 are transmitted exactly to the ski boot 1, so that these movements can be passed on to a ski 102 connected to the ski boot 1. This is in the approach area The Achilles tendon is arranged just above the heel, a support tab 103 which is mounted on an axis of rotation 104 which runs approximately parallel to the sole 25 of the ski shoe and transversely to the longitudinal direction of the sole in order to adapt to the different inclinations. The axis of rotation 104 is fastened in a housing part 105 of the setting device 101 for the template. The housing part 105 is mounted in a guide 106 adjustable in the direction of a double arrow 107. The guide 106 is arranged in a bearing body 108. The bearing body 108 can be rotated about an axis 109 which is arranged in the tailgate 6. Furthermore, a fixing device 110 is provided on the bearing body 108, which has a screw bolt which can be adjusted perpendicularly to the guide 106 via an adjusting wheel and with which the housing part 105 can be fixed in its position relative to the bearing body 108. The housing part 105 has a guide plate 111 which, together with guide slots 112 in a housing 113 of the setting device 101, form a guide device. The housing 113 is articulated in the lower shell part 2 via an axis 115 via a damping device 114. In order to fix the housing part 105 and the housing 113 in a certain relative position to one another in which the tailgate 6 is in its rear end position - as shown for example in FIG. 6, a releasable coupling device 116 is arranged. This consists of an eccentric lever 117, a locking pin 118 and a compression spring 119, which in the present case is designed as a spiral spring. The eccentric lever 117 is rotatably mounted on a pivot axis 120 passing through the locking pin 118. By pivoting the eccentric lever 117 from the position drawn in full lines, in which the locking pin 118 engages in a bore 121 of the guide plate 111, in the swiveled up position drawn with dashed lines, the locking pin 118 is - as also indicated by dashed lines - out of the bore 121 pulled out. This has the effect that the housing part 105 with the guide plate 111 connected to it in motion is freely displaceable along the guide slot 112, bypassing the damping device 114. The tailgate 6 can thus be in any position relative to the lower shell part 2 be pivoted. If, on the other hand, the locking pin 118 is snapped into the guide plate 111, the housing 113 and the housing part 105 form a rigid unit, the position of which is fixed by a stop 123 arranged on a threaded rod 122, which can be formed by an adjustable nut. In the present case, the threaded rod 122 is provided with a bearing eyelet molded onto it or screwed onto it, which is supported on the axis 115. Due to the action of the damping device 114 formed by the threaded rod 122, the stops 123 and 124 and a compression spring 125, the housing 113 is held in the rest position drawn in full lines. If the shaft 4 is now moved forward in the direction of an arrow 126 when the shaft is closed, ie that the lower leg 89 moves in the direction of the shoe tip 22 when the person kneels, this forward movement is delayed or damped by the compression spring 125. Depending on the suspension characteristics of this compression spring 125, which can be formed by a spiral spring, the resistance to be overcome is less or greater. Otherwise, the damping characteristic of the compression spring 125 can be reinforced by the stop 124, that is to say the turning of the screw nut in the direction of the stop 123, or can be reduced in the case of an adjustment in the opposite direction. At the same time, the adjustment of the stop 24 can also be used to determine the setting for the template limitation opposite the stop 123. This results from the longitudinal dimension of the compressed compression spring 125 and the position of the stop 124.

It is of course possible within the scope of the invention to replace the compression spring 125 by any other damping device, for example a gas spring, elastic materials, such as plastics or rubber, by leaf spring assemblies or the like or, for example, also by torsion bars.

Likewise, the fixing device 110 of the setting device 101 can also be designed in accordance with all the possibilities available in the known prior art. Among other things, it is also possible that toothed segments 127 are arranged on the housing part 105 in the region of the guide 106, as indicated schematically. A gear wheel 128 can be assigned to these toothed segments, which, as indicated schematically with dashed lines, can be connected, for example, to a stepping motor or any other motor 129. As a result, the adjustment of the support tab 103 of the heel adjustment can be carried out, for example, via push buttons or remote control.

The advantage of the adjusting device 18, especially the coupling device 116 integrated in this, is that after unlocking the coupling device 116 a very large relative movement between the lower shell part 2 and the tailgate 6 is possible, whereby the wide opening positions shown and described in FIG. 9 can be achieved are.

The combination of the setting device 18 and the setting device 101 shown in FIG. 10 represents only a preferred development of the present invention. Of course, it is also possible to omit the setting device 101 and to remove the housing part 105 without interposing the guide 106 and fixing device 110 with the tailgate 6 connect to.

Another embodiment of an adjustment device 101 for heel adjustment is shown in FIG. To adapt the support tab 103 to the leg 29, a drive shaft 130 is mounted in the lower shell part 2 of the ski boot 1. An eccentric cam 131 is arranged on this drive shaft 130 and connected to it in a rotationally fixed manner. The support bracket 103 is connected in an articulated manner to the cam 131 via an axis 132. The cam 131 can be pivoted via an actuating lever 133 connected in a rotationally fixed manner to the drive shaft 130, so that it can be adjusted between the positions drawn in full lines and the broken lines in order to adapt to the respective course of the leg 29 in this area. Such an adjusting device 101 can of course also be used together with the adjusting device 18 for document damping.

Another advantage of this adjusting device 101 is that the drive parts, in particular the cams 131, are accommodated below the tailgate 6 and thus protected against damage from the outside, and the tailgate 6 does not have to be slotted to arrange them, so that the risk of moisture ingress or the like is likewise is less. In the illustrated embodiment, the support tab 103 is also shown lying directly against the leg 29.

Another embodiment variant of an adjusting device 134 and a buckle arrangement 135 is shown in FIGS. 12 and 13. Thus, the adjusting device 134 for positioning a support tab 103 for heel adjustment consists of a buckle arrangement 135 connected to the support tab 103, which is connected to a carrying strap 137 via a rivet 136. This support band 137 is connected to a holding member 139, for example, by screws 138. Depending on the position of this holding member 139 in the longitudinal direction 26 of the sole, the support tab 103 is more or less distant from the tailgate 6 and can thus be adapted to different anatomical conditions of the leg 29 in the area of the Achilles tendon or in the heel area 27. As indicated schematically, a plurality of bores 140 can be provided in the holding member 139 in order to assume various intermediate positions. This setting can also be made in that the holding member 139 is provided with a toothing 141, which cooperates with a toothing 142 which is arranged in a recess 143 in the tailgate 6. The holding member 139 can be fixed by means of a clamping screw 144 when the teeth 141 and 142 are in engagement. In order to enable the tensioning screw 144 to be rotated from the outside, the nut provided on the inside is anchored in the tailgate 6 in a rotationally fixed manner. By using the toothing 141, 142 and the possible relative adjustment between the holding member 139 and the tailgate 6, a sensitive adjustment of the support bracket 103 is possible.

This support bracket 103 can, however, as shown in the lower part of FIG. 12, also be used to adjust a support band 145, for example if the adjustment of the support bracket 103 is via the Screw 138 and the holes 140 takes place. It is thus possible to center an eccentric buckle 146 arranged in the central region of the support plate 39 on a longitudinal axis of the shoe center, so that the tailgate 6 and the front flap 5 are closed essentially centrally. However, in order, for example, to be able to use the holding member 139 to position the support tab 103 and still be able to align the eccentric buckle 146 with a longitudinal axis or shaft center axis, it is possible to connect the holding member 139 to a locking member 147 which is used to fix one with the eccentric buckle 146 connected detent band 45 is used. This version is shown as a variant in the upper half of FIG. Of course, it is possible to provide the eccentric buckle 146 in place of the carrying strap 145 in both end areas with a detent strap 45 and also to arrange such a locking member 147 in the area of both holding members 139. A completely flexible adjustment of the eccentric buckle 146 can thereby be achieved.

This central pulling action, which is exerted on the support plate 39 in the direction of an arrow 148, is important because it prevents the support plate 39 from tilting relative to the front flap 5, which consists of two front flap parts 149, 150 in FIG. The connecting link between the two front flap parts 149 and 150 is formed exclusively by the support plate 39, so that the front flap parts 149, 150 could be deformed differently in the event of an eccentric pull through the buckle arrangement 135. However, the same advantage of the central pull has a particularly advantageous effect when the support plate 39 is used in conjunction with the design of the front flap 5 as described in FIGS. 2 to 9, since the pin 48 and the guide pin 49 and 50 in the Guide assemblies 51 can not constrain and tilt. However, this also more precisely defines the function of the support surface 24 and its position relative to the instep cover 20 or the weakening line 35.

In Fig. 13 it is further shown that to adjust the movement of the Instep cover 20 at the different pivoting positions of the shaft 4, the slide track 38 can have a greater width 151 than a width or a diameter 152 of the guide member 37 which can be displaced in this slide track 38. As a result, the position of the instep cover 20 can adapt to the different movement radii, namely depending on whether the instep cover 20 pivots about the weakening line 35 or about the holding device 56 of the shell cover 3, as well as adapting to a straight course of the sliding track 38.

FIG. 14 shows a preferred embodiment of an adjusting device 153 in connection with the use of a support plate 39, with which an adjustment to different courses of the shin can be made. Above all, this adjusting device 153 enables the use of the instep cover 20 in cooperation with the support surface 24 of the support plate 39 and thus the same movement mechanism as has already been described with reference to the preceding figures in connection with the weakening line 35 or the axis 21. Between the instep cover 20 and the support plate 39, a wedge cushion 155 is adjustable in a guide slot 154 via an adjusting device 153 formed from a screw 156 and an actuating wheel 157 approximately parallel to the support plate 39. For this purpose, the screw 156 is motionally connected to the wedge cushion 155. If the screw 156 is now moved in the direction of the sole 25 by turning the fixed actuating wheel 157, the pressure point or the course of the instep cover 20 is shifted in the direction of the sole 25 and at the same time a distance 158 to the lower shell part 2 or to that arranged above it Tailgate 6 reduced, whereby a concave transition region 159 between the lower leg 89 and the foot can be compensated.

At this point, it should be expressly pointed out that the anatomical course of the foot and individual parts of the ski shoe in the various exemplary embodiments shown in this application were shown purely schematically and in many cases exaggerated in the proportions and sizes by the function and mode of action of the to illustrate more clearly individual adjusting devices and the movement sequence of the individual shoe parts when the foot moves.

Furthermore, the individual setting devices 18, 55, 101, 134 and 153 can be interchanged in any way and used in any combination in a ski boot 1. In addition, the design of these adjusting devices 18, 55, 101, 134 and 153 can form an independent and independent invention without the inventive design of the instep cover 20 in cooperation with the support surface 24 or the shell cover 3. It should be noted, however, that the combination of the adjusting devices described with the instep cover 20 formed in the manner described above, using a weakening line 35 and / or an axis 21, bring a multitude of further advantages, which particularly make their use in connection with their features according to the invention gives preference to appear.

15 to 17 show, on a larger scale and schematically, a possible embodiment of the buckle arrangement 10 shown in FIG. A support frame 160 of the buckle arrangement 10 is fastened to the front flap 5 with rivets 161, as indicated schematically. But it is also possible to arrange this support frame on the support plate 39. A detent band 162 is guided in the support frame and runs between the base plate connected to the front flap 5 and the ratchet part 15. This is articulated via a push rod 163 to the actuating lever 12, which in turn is rotatably mounted on the support frame 160 via an axis 13. Furthermore, the catch 14 can be pivoted about an axis 164 on the support frame 160. The catch is also adjustable with a slot 165 along a bolt 166. The catch 14 is held in the position shown in full lines in FIGS. 16 and 17 by means of a compression spring 167. To unlock it, it can be pivoted up against the action of the compression spring 167, as shown in FIG. 15, whereby when the actuating lever 12 is pivoted into the position shown in FIG shown position, the ratchet part 15 is lifted from the notch band 162 and thus teeth 168 and 169 of the ratchet part 15 and the notch band 162 disengage. Thus, in the position shown in FIG. 15, the detent band 15 can be pushed back and forth as desired. After releasing the catch 14 and pivoting the actuating lever 12 forward as shown in FIG. 16, the teeth 168 and 169 of the catch band 162 and the ratchet part 15 and the catch 14 come into engagement. Through several successive movements of the actuating lever 12 from the position shown in FIG. 16 to the position shown in FIG. 17, the detent band 162 can be displaced in the direction of an arrow 170, while during the pivoting back of the actuating lever 12 from the in FIG Fig.16 shown position the detent band 162 is held in position by the detent 14.

This makes it possible with simple means to provide a large adjustment path for the detent band 162, but this detent band 162 can also be formed, for example, by any other arrangement such as racks or the like. It is also possible, in various positions, as indicated schematically in FIG. 16, to hook in cables 171 which, like the cable 16 in FIG. 1, connect the front flap 5 and the tailgate 6 to one another in different positions. However, any transmission element can be used between this ratchet arrangement and the parts which can be moved relative to one another, such as front flap 5 and tailgate 6. It is also possible to provide two such buckle arrangements 10, 135 in parallel next to one another in the arrangement shown in FIG. 1, the one buckle arrangement for tightening in the area of the buckle arrangement closer to the upper front end 46 of the front flap 5 in FIG. 2 and the second buckle arrangement for tightening in FIG Height of the buckle arrangement 10 arranged below in FIG. 2 can be used. The advantage of the buckle arrangement 10 as shown in FIGS. 1 and 15 to 17 as a possible exemplary embodiment is that the force can be applied from top to bottom, that is to say in a very favorable direction, and thus high forces without twisting the body such as this is the case, for example, with tension buckles in the area of the tailgate 6 or in the area of the side walls, can be applied.

Of course, the buckle arrangement 10 as shown in FIGS. 1 and 15 to 17 can also form the subject of an independent invention, since the advantages achieved thereby with regard to a central pull when closing the shaft 4 in connection with the actuation directed in the sole direction are significant advantages compared to the currently known buckle arrangements, which are arranged transversely to the longitudinal direction of the shaft or in the region of the tailgate 6. Of course, it is also possible to use such buckle arrangements with actuation in the longitudinal direction 26 of the sole in the region of the shell cover 3 or the forefoot cover 19.

Furthermore, it is also possible in connection with the features according to the invention which arise from the interaction of the support surface 24 with the instep cover 20 and the weakening line 35 or the axis 21, to use any type of adjustment devices for the template, for example also in the area of the front flap 5 . The same applies to the canting setting, i.e. the setting of the side inclination of the shaft relative to the shell can be selected as desired. As variants for such setting devices, reference is made to AT-PSs 378 897, 370 954, 370 956, EP-OS 171 384, EP patent applications 85890152 and 85890153 and DE-OS 28 07 348.

In FIGS. 18 and 19 the ski boot 1 is shown, which consists of the lower shell part 2 with the sole 25, the side walls 7 and the shell cover 3 formed in one piece with the side walls 7, as well as the shaft 4 which can be pivoted about a pivot axis 8 relative to the lower shell part 2 a front flap 5 and a tailgate 6.

The front flap 5 and the tailgate 6 can be brought into a fixed position relative to one another via buckle arrangements 11. In order to limit the forward movement or the relative movement between the shaft 4 and the lower shell part 2 or unhindered in a walking position and to allow damping in a driving position via a damping device 114, an adjusting device 18 for the template is arranged between the front flap 5 and the lower shell part 2. This consists of a coupling device 116, of which an eccentric lever 117 of the locking pin 118 and a spring element 172 forming the damping device 114 is shown.

As can be seen in the drawing, the spring element 172 is arranged in that region of the lower shell part which is covered by the front flap 5. The spring element 172 consists of an approximately U-shaped bracket, each of which has legs 173 at its two ends facing away from one another in the region of the side walls 7, which engage in bores 174 in the lower shell part 2, which form part of the holding device 175. This holding device 175 furthermore also comprises abutments 176, for example molded or fastened on the lower shell part 2, which is arranged between the spring element 172 or the toe 22. If the eccentric lever 117 is moved into a walking position, the locking pin 118 is moved so far away from the lower shell part 2 that the locking pin 118 is located above the spring element 172. In this position, the front flap 5 or the shaft 4 can be moved freely about the pivot axis 8. In order to prevent the front flap 5 from moving forwards or backwards over the overlap region with the lower shell part 2, the abutment 176 or the pin has a height 177 which is greater than a distance 178 between the mutually facing surfaces of the lower shell part 2 and the front flap 5, as can be seen better from FIG. 19.

The pin of the abutment 176 engages in a groove 179 of the front flap 5, which is arranged on the side facing the lower shell part 2. The range of movement or adjustment of the front flap 5 relative to the lower shell part 2 is limited by a counter bearing 180 of the groove 179.

In contrast, the eccentric lever 117 in its in dashed lines indicated position, that is, pivoted into the driving position, the locking pin 118 approaches the lower shell part 2 in such a way that, when the shaft 4 moves, it engages in the bore 121 of the guide plate 111 which is connected to the spring element 172. For this purpose, it is under a prestress directed against the guide plate 111, which can be applied by means of a spring element.

If the locking pin 118 is engaged in the bore 121, the front flap 5 is connected in motion to the lower shell part 2 via the spring element 172 and the front flap 5 is thereby damped during its movements relative to the lower shell part 2. If a counter bearing 180 is arranged on the side of the spring element 172 facing the tailgate 6, then the movements from a defined central position in the direction of the tailgate 6 can also be damped accordingly. Depending on the distance between the locking pin 118 and the counter bearing 180, the damping effect can be stronger or weaker.

20 and 21 show another embodiment of an adjusting device 18 designed according to the invention for the template or template damping, in which the damping behavior of a spring element 172 can be changed by an adjusting device 181.

In this exemplary embodiment, the spring element 172 used is that which has already been shown in FIG. 18 and has been described in more detail. The same reference numbers are therefore used for the same parts. The spring element 172 is arranged in that area which is covered by the front flap 5. It consists of an approximately U-shaped bracket, each of which has legs 173 at its two ends facing away from one another in the region of the side walls 7, which are suspended in the lower shell part 2. In order to prevent the front flap 5 from pivoting too far towards the rear flap 6, a slot guide shown in FIG. 19 can be provided in the front flap 5, wherein the pin engaging in the groove 179 can be independent of the abutment 176. In this context, it is of course also possible to provide a corresponding groove in the lower shell part 2 and to store a pin which engages in this groove in the front flap 5. If this pin is adjustably arranged in the front flap 5 in a longitudinal slot, it is possible to prevent the maximum end positions of the front flap. If two independently adjustable pins are provided, the front and rear end positions of the front flap can be set independently of one another. This can also be achieved, for example, by the housing 113 being adjustable relative to the front flap 5. This adjusting device comprises a threaded spindle running in opposite direction to the sole 25 with opposing threads, a traveling nut 183 being arranged on each of the threaded sections 182 and being connected in motion with an adjusting strip 184. A pin 185 forming the abutment 176 is provided on the adjusting strip 184, against which the spring element 172 is supported. The adjustment strip 184 is guided in a recess or a groove 186 in the lower shell part 2. As a result, the pin 185 forms a fixed abutment against deformations of the spring element 172 under the action of the locking pin 118.

The structure of the coupling device 116 can be seen more clearly from FIG. 21. This comprises an eccentric lever 117 which is arranged on the surface facing away from the lower shell part 2 and is connected in motion to the locking pin 118 via a pivot axis 120. The pivot axis 120 is mounted off-center on the eccentric lever 117, so that when the eccentric lever 117 is shown in full lines, the locking pin 118 extends through the front flap 5 and the two-part housing 113 of the coupling device 116 arranged on the side facing the lower shell part extends into a guide plate 111 which is adjustably guided in guide slots 112 of the second part of the housing 113 arranged on the side of the front flap 5 facing the lower shell part 2.

The guide plate 111 is provided with a bore 121 into which the locking pin 118 engages and thus establishes a movement connection between the front flap 5 and the guide plate 111 with the spring element 172. The locking pin 118 is supported in the housing 113 by a compression spring 119 which presses the locking pin 118 relative to the housing 113 in the direction of the lower shell part 2. If the eccentric lever 117 is pivoted into the position drawn in full lines and the locking pin 118 is not in a position covering the bore 121, pivoting of the front flap 5 or of the shaft 4 and a relative displacement between the front flap 5 that results therefrom can and the guide plate 111 an automatic locking of the locking pin 118 can be achieved in the bore 121.

By turning or pivoting the eccentric lever 117 into the position drawn with dashed lines in FIG. 20, the locking pin 118 is raised against the action of the compression spring 119 and pulled out of the bore 121. As a result, the free relative mobility between the front flap 5 and the lower shell part 2 is achieved.

22 and 23 show another embodiment of an adjusting device 18 between a front flap 5 and a lower shell part 2. An approximately C-shaped metal bracket is again provided as the spring element 172, the legs 173 of which engage in bores 174 of the lower shell part 2. The pin 185 forming the abutment 176 is arranged on adjustment strips 184 which run between the lower shell part 2 and the front flap 5 and each with a traveling nut 183 which are mounted on two threaded sections 182 and 187 with opposite threads, for example a right-hand and a left-hand thread connected. The two threaded sections 182 and 187 are arranged on a threaded sleeve 188, which is provided with recesses 189 for coupling to the eccentric lever 117 and between the eccentric lever 117 and the threaded section 187 pass through the lower shaft part 2 and its opposite end in a likewise in Lower part 2 arranged bearing 190 is supported.

Longitudinal slots 191 are arranged in the threaded sleeve 188, through which a guide pin 193 arranged in a push rod 192 projects, which engages in a groove 194 of the locking pin 118. The guide pin 193 is biased by a compression spring 119 in the direction of the threaded portion 187. Depending on the position of the eccentric lever 117, the push rod 192 can now assume a different relative position with respect to the threaded sleeve 188 and, accordingly, the locking pin 118 engages in the bore 121 of a coupling part 195, which is connected in motion to the spring element 172. If, on the other hand, the eccentric lever 117 is pivoted downward against the lower shell part 2 in the illustration shown in FIG. 22, the locking pin 118 moves completely out of the bore 121. As a result, the front flap 5 is uncoupled from the spring element 172 and can be pivoted freely in relation to the lower shell part 2.

In contrast, this decoupled position is already shown in full lines in FIG. 23, in which case the locking pin 118 has already emerged from the bore 121 of the coupling part 195. Free movement of the shaft 4 or the front flap 5 with respect to the lower shell part 2 is now achieved.

Of course, it is also possible to produce the coupling device 116 with the push rod 192 while omitting the threaded sleeve 188 and to provide no or another known adjusting device 181 for changing the damping characteristics. Furthermore, it is also possible to provide any other type of adjustment device for the damping properties.

It is also advantageously possible to use as spring elements 172 such as are described in our parallel patent applications A 1960/87 and A 1961/87, the legs deforming there either with the housing 113 or the guide plate 111 in movement connection have to be brought and thus form the abutment, by means of which the front flap 5 is supported on the lower shell part 2 when the coupling device 116 is in engagement. The subject matter of the two older own patent applications A 1960/87 and A 1961/87 is thus made the disclosure content of the present application.

24 shows a spring element 172 which is formed by a U-shaped elastic spring clip 196. This is inserted into a recess 197 of the shell 2 and is supported with its leg 198 on an end wall 199 of the recess 197 facing the tip of the shoe, only one half of the outer side of the ankle being shown of the ski boot 1. Between the leg 198 and another leg 200 of the U-shaped spring clip 196, a stop 201 is arranged at a distance 202 from a leg 203 of the U-shaped spring element 172, which runs in the direction of the front flap 5 and with the guide plate 111, for example, in FIG Fig.21 shown coupling device 116 is motionally connected. The housing 113 of the same is motionally connected to the front flap 5, as is schematically indicated in a simplified manner. The eccentric lever 117 and the locking pin 118 are also shown. With regard to the functioning of the coupling device, reference is made to the explanations relating thereto in FIG. 21. The front flap 5 of the ski boot 1 is supported on the leg 200 via the guide plate 111. By changing the distance 202 of the stop 201 from the leg 203, when a supporting force 204 of the same size acts on the leg 200, different spring paths result due to different bending lengths of the leg 200. These effect a different damping characteristic, since in the setting shown in full lines, due to the spring characteristic of the leg 200 acting as a bending rod, a greater damping path 205 is achieved compared to a damping path when the stop 201 is set, as shown in broken lines. The damping behavior in the setting shown in full lines is therefore softer and in the setting shown in dashed lines harder. This means that when an equally high supporting force acts on the lower leg covers a longer distance until the supporting force is completely diverted into the lower shell part 2. As a result, the transmission of force between the foot of the user and the ski boot 1 or the ski attached to it takes place more slowly in the setting shown in full lines, as is required, for example, when driving in deep snow in order to prevent a sudden transmission of force between the foot and the ski shoe or the ski of the ski "dives away" or digs in deep snow, which in many cases leads to the fall of the user of the ski shoe. On hard slopes, on the other hand, it is desirable that the forces required to control the skis are implemented as immediately as possible in order to avoid an undesirable slipping when swinging, especially on hard slopes in steep terrain. By changing the distance 202, the spring characteristic of the spring element 172 can therefore be varied within a wide range in a simple manner. Of course, it is also possible that the end wall 199 of the recess 197 is provided with a cross-sectional shape adapted to the cross-sectional shape of the spring clip 196, so that the spring element 172 can be prevented from jumping out of the recess 197 during use of the ski boot 1. However, this can also be achieved, as indicated schematically, by holders 206 fastened to the lower shell part 2.

In order to adjust the stop 201, it can be motionally connected to a traveling nut 183 which is adjustably mounted on a threaded spindle 207. It is both possible to arrange the stop 201 on its own threaded spindle 207. However, it is also possible to provide only a single threaded spindle 207, which is provided with counter-rotating threads, so that when the same is rotated, the stop nut 183 assigned to the stop 201 shown and a further stop 201 associated with the inner ankle side of the ski shoe 1 and arranged in mirror image with respect to the axis of symmetry in relation to one another opposite directions can be put apart or together.

Of course, it is also possible with this embodiment support the spring elements 172 by stops firmly connected to the lower shell part 2 in the curved transition region between the legs 198, 200. Equally, however, it is also possible, as shown, to design the stops 201 on their side facing the curved end regions of the spring element 172 with a curvature corresponding to the spring element 172, as a result of which the adjustment path of the stops can be optimally utilized. The above-described embodiments according to FIGS. 18 to 24 form their own independent inventive solution independent of the other features in the further exemplary embodiments. Likewise, the design of the spring elements 172 can be varied in many ways and, instead of the bow-shaped or U-shaped spring elements shown, C-shaped spring elements or thick springs, torsion springs or the like can also be used.
