Abstract

Safety ski binding has a sole grip swivelling sideways when a pre-determined release force is reached. The grip is equipped with two side jaws standing in a 'V' shape in relation to each other with sliding insets for the boot in order to centre the sole of the ski-boot pressd against the jaws under spring pressure. The point where the boot adjoins the sliding insets is adjustable sideways. The sliding insets (13) are adjustable relative to the side jaws (12) rigidly fixed to the sole grip (11) in such a way that the boot contact points (14) may take up at least two different positions from the centre length axis of the binding.

Description

The invention relates to a safety ski binding with a

with a predetermined release force, the sole holder can be swiveled out to the side, which are two V-shaped for centering the sole of a spring-loaded ski boot having mutually standing side jaws with sliding inserts for the shoe, wherein the point where the shoe rests on the sliding inserts is laterally adjustable.

Safety ski bindings of this type are already known; (DE-OS 1578 720, 2007 30G; DE-AS 1 403 54 /; FA 2282 919), where the sole holder has two Has side jaws which are connected to a support part via joints and their distance from one another by various means such as washers, screws, etc. is changeable. Furthermore, it is already known (AT-PS 206 338), the rear ends of the sole holder to be separated from the rest of the main part and by means of teeth and a to adapt the corresponding screw connection to the respective sole shape.

To adapt sole holders to different sole thicknesses are already convertible slip-on parts on the sole hold-down device known: (DE-OS 1 905 440).

As such, side jaws that are V-shaped to one another are suitable provided sole holder to this, due to their self-centering effect shoes with to accommodate different sole widths, the disadvantage of this self-adjustment the connection to different sole widths consists in the fact that the sole depending on the width, more or less on the axis of rotation or the axes of rotation of the sole holder is approximated, so that the EIebelarm occurring in the side release between the side release force and the axis of rotation are subject to uncontrolled changes is.

The well-known safety ski bindings with laterally adjustable side jaws (e.g. DE-OS 2 627 305) are expensive to manufacture and assemble, see above that they are particularly unsuitable for mass production.

The task of the invention, on the other hand, is to create a secure ski binding of the type mentioned to create which on a one-piece sole holder for sole centering has side jaws arranged in a V-shape to one another and on easiest way to adapt to different sole width tones, whereby however, the lever arm from the side release force to the pivot axis is largely constant should be held.

Also the subdivision of the sole holder into a carrier part and on it somehow movably arranged side jaws should be interrupted in order to and assembly costs to be kept low. The invention is preferably intended to be applied to toe cheeks come into use, which are designed as a single-joint or to the side of the central longitudinal axis have arranged tilting edges, wherein the sole holder is formed in one piece and cooperates with sl.fixed counter bearings.

To solve the problem, the invention provides that the Sliding inserts can be adjusted in this way relative to the sole jaws, which are fixedly arranged on the sole holder are that the shoe application points are at least two different distances from the Can occupy the central longitudinal axis of the binding. According to the invention, the in the side jaws anyway existing sliding inserts are used to adjust the width. No or only a few of the simplest additional parts need to be used will. This means that despite the uncomplicated assembly, a safety ski binding is included Width adjustment of the side jaws created with the width adjustment takes place in such a way that the lever arm is between the side release force and the lateral pivoting axes remains essentially constant.

Although two side jaw width settings are generally sufficient are, as there are generally only two standardized sole widths for such bindings come into question (insole or adult sole), can look for an advantageous Further development of the invention between the at least two distances can also be arbitrary Intermediate settings may be possible.

A first practical embodiment is characterized in that the sliders detachably attached to the side jaws in two at least two different distances between the shoe contact point and the central longitudinal axis Positions can be attached to the side jaws. The sliding pieces are expedient for this purpose can be changed around 1800. The sliders can thereby be essentially perpendicular the horizontal axis standing on the side jaws can be repositioned, with the sliding inserts Seen in the longitudinal direction or in the vertical direction, two different distances to the central longitudinal axis have protruding areas. In one plug-in position then lies the large, in the other the small distance between the shoe contact point and the central longitudinal axis in front.

But it is also possible that the sliders in the longitudinal direction of the ski are attachable in at least two different positions, which also two different width settings can be realized. The bigger one The area guaranteeing the distance can be combined with the area defining the smaller distance Area of the sliding pieces to be connected by a predetermined breaking point. Will this bond from adjusted the larger distance to the smaller distance of the sliding inserts, so the area ensuring the greater distance is canceled so that it does not protrudes over the side cheeks towards the shoe and thus hinders the use of the binding he t.

Although basically every vertical sliding guide for the arrangement suitable for the sliding pieces, the sliding pieces are preferably in vertical dovetail guides arranged.

If two areas of the sliding pieces are connected by a predetermined breaking point, so the invention provides that for the sliders as a whole and for the lesser Distance-defining area in each case a dovetail guide that functions on its own is provided so that even after the breaking off of the ensuring the greater distance Area still a perfect vertical guide for the one defining the smaller distance Area of the slider is guaranteed.

Another practical embodiment is the sliding pieces by spacing members effective between the side jaws and them at a distance of the central longitudinal axis adjustable.

The sliding inserts are located to achieve the greater distance preferably directly on the side jaws, while the spacers for Setting the smaller distance between the sliding inserts between the side jaws and Sliding inserts are used.

This embodiment is characterized by an advantageous formation of a ladder in that the two sliding pieces are made from a cinzi; cn, the inner shape of the side jaws adapted piece stand at one point between the two side jaws at the Sole holder is attached and both of which form the sliding inserts, resilient Arms can be acted upon by the spacing members. But the training can also be so that the ends of the sliders facing away from the shoe are attached to the sole holder are and the arms extending to the shoe can be acted upon by the spacer members are.

The spacers are advantageously provided in the side jaws, Screws standing essentially perpendicular to the legs of the V, whereby a continuous width adjustment is possible.

A particularly advantageous embodiment is characterized in that that the V-like mutually arranged sliders are attached to the screws. Depending on the screw-in depth of the screws, a more or less large one will be Realized spacing of the sliding inserts. Any additional support for the sliding inserts on the side jaws is not required here.

Characterizes a particularly simple implementation of the inventive concept in that the spacers between Seib-enbacken and sliding pieces can be attached Plastic bolts are.

The spacers can also be placed between the side jaws and sliders be effective eccentric, which from above, for example through a slot inserted coin can be twisted.

The spacers between the side jaws and sliding inserts can also be used arranged wedges, which through a predetermined breaking point with the sliding inserts can be connected.

At the transition from the smaller to the larger distance of the sliding inserts the wedge can thus be broken off.

According to FIGS. 1 to 5, about a vertical axis 26 against a resilient holding force laterally pivotable sole holder 11 two essentially V-shaped to each other arranged side jaws 12, the inside running vertically Have dovetail guides into which slide inserts from above or below 13 are inserted. The sliding inserts have two seen in the longitudinal direction of the ski Areas protruding differently from the side jaws 12? 3 'or 13 " on.

According to FIG. 3, the sliding inserts are made by vertical displacement the dovetail guides 18 are removable and can be rotated around 1800 about the axis 1 or by turning it in the direction of the arrows f according to FIG. 5 so displaced that the area 13 "initially removed from the shoe is in the area of the shoe sole reaches, while the area 13 ', which is initially located in the area of the shoe sole is turned away from the shoe, In Fig. 1, the one position of the sliding inserts 15 is on the left from the central longitudinal axis 15, the other position to the right of the Central longitudinal axis 15 shown. In use, both slide inserts 13 always take occupies the same position, i.e. either the left or the right illustrated in FIG The push force F exerted by the heel binding against the sole holder 11 pressed shoe 24 touches with its sole the sliding inserts 13 at the shoe contact points 14th

Take the sliding inserts 13 in Fig. 1 to the left of the central longitudinal axis 15, the shoe is at 1lp on the one that is further set back Area 13 '.

In this case, the shoe contact point is 14 from the central longitudinal axis 15 the distance a '.

After turning the sliding inserts 15 according to FIG the further inwardly projecting area 15 "at 14 in contact with the narrower one Sole of the ski boot 24. The distance between the shoe contact point 14 and the central longitudinal axis 15 is now lower and is a ".

The distances a 'and a "can be designed so that optionally one Adult shoe sole or a children's shoe shell can be used in the binding can without changing the length of the lever arm L of the side release force K will. The triggering behavior of the indung thus remains independent of the one used Ski boot unchanged.

From Fig. 2 it can be seen that the side jaws 12 having Sole holder 11 is rotatably arranged on a base plate 27, which in turn is attached to the ski 28. In addition to the side jaws 12, the sole holder 11 also has nor a hold-down device 5) 7, which optionally also on the side jaws can be arranged.

According to FIGS. 4 and 5, the further inwardly projecting areas are 13 ″ of the sliding inserts 15 relative to the more outwardly lying areas 13 ′ in the IIöhe offset, again in such a way that by pushing out the sliding inserts 13 down from the dovetail guides 18 and twist u the axis 16 the two areas 13 ′, 13 ″ can be interchanged with one another by 180 ° '*' can both slide inserts 13 either the left in FIGS. 4 and 5 Central longitudinal axis 15 or to the right of the central longitudinal axis 15 illustrated position take in. The distance between the shoe contact point 14 and the central longitudinal axis 15 is then again either a 'or a "with unchanged lever arm length.

In the embodiment according to FIG. 6, there are sliding inserts 15 from a front one having the smaller distance a ″ from the central longitudinal axis 15 Area 13 "and one connected to it via a Sellhruchstelle 17, the larger one Distance a 'defining rear region 15'. According to Fig. 6 oind two into one another nested dovetail guides 18 provided so that either the entire sliding insert 13 according to the illustration to the left of the central longitudinal axis 15 in a Dovetail guide 18 can be used or as shown to the right of of the central longitudinal axis 15 only the front area 13 ″ facing away from the shoe 24, which is offset to the rear for the purpose of contact with the sole of the ski boot 24. Then the side The area 13 'protruding from the shoe is broken off in order to allow the use of the binding not to hinder.

The exemplary embodiment according to FIG. 7 allows continuous adjustment the distance of the sliding inserts 13 from the central longitudinal axis 15. For this purpose, the Slide inserts 13 combined into a single component, which at 20 on the from Shoe 24 is attached to the side facing away from the sole holder 11. The sliding inserts 13th Extend themselves as the V-shape of the side jaws 12 adapted resilient arms for Shoe to where they rest against the shoe sole at 14. In the left of the The basic position shown in the center longitudinal axis 15, the sliding inserts 15 lie directly on the side jaws 12. In the area of the shoe contact point 14 is in a threaded hole 30 of the Seitenbacl.en 12 screwed in a plastic screw 19, which in essence is adjustable perpendicular to the side jaws and the sliding inserts 15 forming arms more or less resiliently pushes inwards. '.tI. in Fig. 7 to the left of the central longitudinal axis 1 5 the basic position of the sliding insert: o 15 with the distance a 'of the shoe contact point 14 from the central longitudinal axis 15 is illustrated shows: the right half of Fig. 7 the plastic screw 19 in almost complete turned-in state in which the shoe contact point 14 is only the distance a ″ from the central longitudinal axis 15.

In the embodiment according to FIG. 8, the sliding inserts 13 firmly attached to the plastic screws 19. This allows the distance between the shoe contact points 14 of the central longitudinal axis 1) can also be continuously changed without the flebelarra the length of the side release force is changed significantly.

In the embodiment of FIG. 9, the sliding inserts 13 are also designed as resilient arms, which, however, are independent of each other with the from Shoe 24 facing away from the end on the sole holder 11 are attached. In the left of the The sliding inserts 13 rest on the basic position shown in the center longitudinal axis 15 their entire length on the side jaws 12.

The second position corresponding to a smaller width setting the sliding inserts 13 designed as resilient arms is right illustrated by the central longitudinal axis 15, between the sliding inserts 13 and the For this purpose, the side jaws 12 have a 21 synthetic stiffener / inserted in the area of the shoe contact point 14, which is prevented from jumping out by an approximately semicircular recess 51 will.

In the embodiment of FIG. 11, the two are as resilient Arms shaped slide inserts 15 again as a substantially V-shaped component designed, which is attached to the sole holder 11 at 20. Between those in the area the shoe contact point 14 located end regions of the sliding inserts 13 and the Side jaws 12 are arranged eccentrics 22, which are accessible from above Screw head 52 are rotatable. In one, to the left of the central longitudinal axis 15 the illustrated rotational position, the sliding inserts lie flat on the side jaws 12 on.

In the other end position shown to the right of the central longitudinal axis 15 are the sliding inserts 13 from the maximum of the side jaws 12, so that the minimum Distance of the shoe contact point 14 from the central longitudinal axis 15 is realized. Of the The eccentric bolt is expediently also economical to manufacture Plastic part formed, Fig. 13 shows a similar embodiment as that 9 and 10, but instead of the plastic bolt 21, a wedge 25 between the sliding inserts 13, which are designed as resilient arms, and the side jaws 12 can be pushed in is to the smaller distance of the shoe contact point 14 from the central longitudinal axis 15 to be defined. According to the invention, the wedge 25 can also have a predetermined breaking point be connected to the sliding inserts 15, so that initially the smaller width setting is realized and by breaking off the wedge 23 of the sliding inserts 13 the wider adjustment of the slide inserts 13 can be realized.
