CONSTITUTION: A support device comprises a fixed shaft 7 installed in a transverse direction to a ski 5, a supporting member connected by a hinge around the fixed shaft 7, and the support members 30a, 30b installed between the ski 5 and the supporting member, and having the cushioning performance, the fixing shaft 7 is positioned in an area localized at a lower part of a ski boot 1, one 30a of the supporting members is positioned in front of the fixed shaft 7, and the other 30b of the supporting member is positioned at the back of the fixed shaft 7.

Description

[Detailed description of the invention]

The present invention relates to a support device for a ski binding for integrally connecting a ski boot to a ski board.

For alpine skiing, skiers' shoes generally have two fasteners: a front (toe) stop that holds the front end of the shoe and a rear (heel) stop that holds the back end of the shoe.
It is held to the ski by a stopper. These two bindings are generally integrally connected to the ski by screws. The shoe does not rest directly on the ski, but each of its ends is supported on a respective member of the front and rear bindings, and the exchange of forces between the ski and the skier is carried out between these two shoe supports. It is done through the area. Vibrations, vibrations or shocks applied to the ski are transmitted directly to the shoe from these two bearing areas. These vibrations, jolts, or impacts form part of the information that the skier perceives through his/her shoes.
Based on this information, skiers control their movements. If these vibrations, shakes, or shocks are directly transmitted, they can be harmful. This is because the magnitude of such vibrations is excessive compared to the level of other information the skier receives, and as a result, these vibrations, shakes, or shocks momentarily mask other information. It is.

It is also desirable that the forward and rearward bias of the ski by the skier be reduced. This is because very severe shocks cause excessive reactions in the ski, which impede the steering of the ski.

The invention makes it possible, on the one hand, to screen the information received from the ground and thereby prevent the skier from making inappropriate corrective movements, and, on the other hand, to screen the information received from the ground and, on the other hand, to monitor the information in front and behind the skier on the ski. This allows the motion to be attenuated.

For this purpose, the front and rear bindings of the ski are not fixed directly on the ski, but on a support member having approximately the same width as the ski. These bindings hold the shoe at its front and rear ends, and the shoe is supported on each member of the front and rear bindings in contact with this support device at each of its ends. A rigid assembly of "support device - front and rear binding - shoe" is thus obtained. In its central part, the support device carries a cover with side walls that, for example, closely cover the sides of the ski. A shaft parallel to the surface of the ski passes transversely through the ski and the cover side wall, thereby integrally connecting the support device carrying the shoe onto the ski.

This structure is such that when the support device is parallel to the ski, the support device does not come into direct contact with the upper surface of the ski. The support device can thus pivot about its axis until each of its front and rear ends alternately comes into contact with the upper surface of the ski. This makes it possible to insert a more or less compressed damping material between the ski and the aforementioned support device at each end of the support device.

[0007] In this way, the rocking, shaking, or impact generated by the ski is weakened and transmitted to the skier via the cushioning material. Also, since the support device swings about its axis, the external forces exerted by the skier on the ski in the forward or backward direction are varied and weakened by this same damping material.

[0008] Patent application No. 90005 by the present patent applicant
No. 66 already exists. This patent application specification includes:
A plate is found which carries the binding and rests on the upper surface of the ski via an elastic slide. However, in order to fix this plate on the ski, it is not possible to fix it by means of an axle, but by means of lateral flanges which are located under the central part of this plate and which engage internally with each other and which can slide.
This is done by means of a two-part device, a male part and a female part, which allows a vertical movement of this central part.

German Patent No. 2,301,966 also describes a shoe-carrying plate whose ends are supported on the ski via elastic members. However, this concerns part of the safety mechanism. This subassembly is fixed to the ski and is retained on the ski by a cover that cooperates with a member of the plate that can be released when a vertical stress is applied to release the plate from the ski.

German Published Patent Application No. 3932438A1
In this specification, the structure of the plate on which the shoe is placed is again taken up. This plate is held on the ski via a cover carrying a vertical hole through which an axle fixed in the plate passes. However, in this case, the mechanism constructed in this way allows the axis of the plate to move vertically in response to the deformation of the ski.

Other characteristics and advantages of the invention will become apparent from the description given below with reference to the accompanying drawings, given by way of non-limiting example only.

1 and 2 show a ski 5 and a shoe 1 held on a plate 2 by means of a front (toe) stop 3 and a rear (heel) stop 4. FIG. The toe and heel stops are fixed on the plate 2 by any means known per se, for example by screwing.

The shoe rests on the plate 2 via the front and rear ends of the shoe on the bearing areas 9, 10 of the toe stop 3 and the heel stop 4. The plate 2 is elongated and has a width approximately equal to the width of the ski 5 and a length that includes both longitudinal end positions occupied by the binding. The plate comprises in its central part two lateral legs 6, which cover the sides 18 of the ski 5 and are localized at the bottom of the shoe 1 and traverse the ski; Furthermore, a cover is formed which cooperates with a fixed axis parallel to the underside 8 of the ski. As a result, the plate 2 is hinged about this axis 7 and can therefore swing about this axis.

At each end of the plate 2 (front bearing area 9
and in an area located below the rear bearing area 10), a front bearing part 30a and a rear bearing part 30b made of cushioning material are located between the lower side 12 of the plate 2 and the upper side 11 of the ski 5. The support member 30a is located in front of the shaft 7, the support member 30b is located in the rear of the shaft 7, and each support member is supported transversely over substantially the entire width of the ski.

FIGS. 3 and 4 show a modified embodiment of the cover 6. FIG. This cover has an independent U-shape and is fixed to the central part of the plate 2. The cover is removable and has an axis 7 relative to the fulcrums 9, 10.
It is adjustable in the longitudinal direction of the ski so that the position of the ski can be changed. The plate 2 includes two series of holes 14 for adjusting the positioning of the cover thereon. Each series of the two series of holes 14 is arranged along a plane P perpendicular to the longitudinal axis of the plate 2 . The cover 6 has an inverted U-shape and its two parallel wings 16 closely cover the sides 18 of the ski 5. Two pipes 15 are fitted into two holes 14 in the plate 2 on the upper surface of the cover 6 and on opposite sides of the wing sections 16 . These pipes are threaded to receive respective screws 13 in order to fix the cover 6 to the lower part of the plate 2 in the desired longitudinal position.

To change this position, remove the two screws 13, place the two pipes 15 in the other two holes 14, move the cover 6, and screw the screws 13 into the plate 2. It is only necessary to re-fix the cover 6 to the lower part of the .

FIGS. 5 and 6 show other constructional aspects of the cover 6 and the pivot point of the plate 2. FIG.

In this case, the cover 6 is integral with the ski and is fixed to the upper surface 11 of the ski by two screws 19. This cover includes two wings 16 pointing in the direction of the plate 2 , which plate includes at least one transverse bore 21 for receiving an axis passing through the bore 22 of the cover 6 .

One means of obtaining these bores 21 is shown in FIGS. 5 and 6. The metal plate constituting the plate 2 is continuously stamped upward and downward to form a corrugated shape 24,
25 and these corrugations define the bore 21 corresponding to the diameter of the shaft 7.

After the cover 6 is thus fixed to the ski 5, the shaft 7 can be inserted into a desired one of the inner holes 21.

FIG. 7 shows how the plate 2 can be mounted on a ski with non-parallel sides 18. In this case, the cover 6a is fixed to the upper side of the ski 5, and its wings 16a are supported on the lower part of these side surfaces 18. Plate 2 includes the same cover as shown in FIGS. 1 and 2. In this case, the shaft 7 passes through the ski 5, the wings 16 constitute the cover of the plate 2, and the wings 1 of the cover 6a
6a is fixed on the ski 5. In this example,
All or part of the solutions shown in FIGS. 3, 4, 5 and 6 can be combined.

FIGS. 8 and 9 show how the bearing members 30a, 30b are attached to the lower part of the plate 2, which has two holes 28 drilled at each end. Each support member 30a, 30b
includes two projections 29 which are accommodated in holes 28 which allow the bearing member to be removed. Since the support members 30a, 30b are attached without any gap between the lower surface 12 of the plate 2 and the upper surface 11 of the ski 5 (that is, in a compressed state), the role of the protrusion 29 is simply to The aim is to prevent any lateral movement of the bearing members 30a, 30b relative to the plate 2. supporting member 30a,
At least one of 30b is prestressed at rest and means are provided for varying this prestress. A first solution consists in having a set of bearing members whose thickness E can vary. The greater the thickness E, the greater the precompression force for a given material. A second solution consists in keeping the thickness E of the bearing members 30a, 30b constant and using one or more materials with other damping properties. In any case, these solutions also apply to both bearing members 30a, 30b or to the front bearing member 30a or the rear bearing member 30 in order to obtain different damping forces at the front and rear.
It is uniformly applied to at least one of b.

FIGS. 10 and 11 show the support member 30a,
30b shows two possible configurations. Figure 10 is Figure 8
and a bearing member as described in FIG. 9 . The width of this bearing element is approximately equal to the width of the plate 2 and it is supported transversely over the entire width of the upper surface 11 of the ski. In contrast, FIG. 11 shows the case in which, at least at one end of the plate 2, the bearing element is composed of at least two elements located on either side of the central axis of the ski. In this case, each support member 30a, 30b is not supported over the entire width of the upper surface of the ski.

FIG. 12 shows another embodiment of the bearing members 30a, 30b. The front support member 30a and the rear support member 30b are connected to each other and occupy almost the entire space between the plate and the ski. The ski 5 is hollowed out on its upper surface 11 along a contour 31. The space defined by this contour 31 and the lower surface 12 of the plate 2 is occupied by bearing members 30a, 30b, each of which comprises one or more parts made of a material with different damping properties. It can be manufactured.

It goes without saying that the invention is not limited to the embodiments described and shown by way of example, but includes all equivalent techniques and combinations thereof.
