Description

[Detailed description of the invention] Shoe base plate for ski binding The present invention relates to a shoe support plate connected to a front unit of a ski binding. Ru.

In general, ski boots have a front binding unit and a rear binding unit that connect the skis to each other. held on top. The ski boot is also connected at its front end to a front binding unit. It rests on the base plate. In the rear part of the ski boot, the rear binding unit It also rests on a support connected to.

The currently known base plate consists of a layer of material with a low coefficient of friction that rests on the sole of the shoe. Includes a pedestal with parts. This layer may be made of polytetrafluoroethylene, for example. Consists of the upper surface of the board.

Support plates of this type are known, for example, from French patents Nos. 2,533,832 and 261. It is described in each specification of No. 5748. The former is a combination of a pedestal and anti-friction plate by adhesive. The latter describes assembly by mechanical means such as a ratchet wheel. It is related to.

Anti-friction platelets are particularly useful when inserting the ski boot into the tightened lining or when releasing the ski boot laterally. At times, parts of the ski boot are subject to high stress.

Additionally, the assembly of the anti-friction platelets to the pedestal is known to deteriorate over time. , some anti-friction platelets may partially or completely detach from one seat.

Therefore, it is important that the base plate can be removed so that it can be replaced with a new plate. be.

European Patent No. 404848 describes such a removable support plate. There is. However, a drawback of this device is that the assembly of the support plate to the fastening unit is difficult. This is done using two rear screws to assemble the fastener onto the key plate. Ru. Therefore, to replace the base plate, partial removal of this screw and then Requires its reinstallation. In such operations, these screws in the ski locking is impaired, thereby impairing assembly of the binding onto the ski.

Additionally, with this device the entire pedestal is replaced, and in this regard there are Even though the sexual platelets may be damaged, the pedestal itself is often not. It should be noted that it is not accepted.

The choice of material for the pedestal can also be problematic. In fact, this pedestal, on the one hand, On the other hand, the method of assembling antifriction platelets must withstand two mechanical forces from Therefore, in order to assemble antifriction platelets by gluing, In order to There is. However, this material does not necessarily respond to the mechanical stress that the base plate receives from the shoe side. It is not compatible. In this regard, French Patent No. 2615748 Mechanical bonding of antifriction platelets as described in It should be noted that this invention, which only considers chemical bonding, is not considered. It is. In other words, in the present invention, the bonding of the antifriction platelets to the support member is deterministic. be. i.e. - when debonded, the anti-friction platelets destroy the platelets or support; It cannot be removed without doing so.

One of the objects of the invention is to provide a bearing plate in which the part carrying the anti-friction platelets can be easily replaced. It is about providing.

Another object of the invention is to provide a base plate that can be replaced without requiring disassembly of the entire base. It's about doing.

Another object of the invention is that the pedestal is capable of resisting stresses of a completely different nature, in particular of anti-friction platelets. Connection method and bearings that can respond to mechanical stress due to ski boots on the base plate Other objects and advantages of the present invention, which consist in providing a board, will be apparent from the following description. However, this description is provided for reference only and is not limiting.

The base plate connected to the front unit of the ski binding is attached to the bottom plate of the binding unit. It has a pedestal that extends rearward and is integral with this sole plate, and a small antifriction plate on which the sole of the shoe is placed. The purpose is to support the front part of ski boots. The anti-friction platelets are replaceable. Ru. A feature of this base plate is that the base includes a base plate and a support of anti-friction platelets separate from the base plate. that the anti-friction platelets are positively bonded to the support, and that the supports are mutually bonded; removably coupled to the substrate by a mating means and a reversible locking means; be.
