Definitions
- the invention relates to a support plate for a shoe, in particular a shoe used in sliding sports such as skiing.
- each shoe rests on a support surface specially arranged to receive it.
- the shoe rests on two support plates located respectively towards the front end and the rear end of the shoe.
- the invention aims to improve such a device.
- one of the objects of the invention is to propose a support plate of this type whose construction is particularly simple.
- Another object of the invention is to provide a support plate which offers better protection against snow and ice.
- the support plate according to three juxtaposed solid zones, a central zone and two lateral zones.
- the middle zone is relatively rigid, to support the shoe, and at least one of the lateral zones is elastically deformable to collapse under the effect of a lateral tilting stress on the shoe.
- Another object of the invention is to provide a support plate which generates only reduced friction for the shoe in the event of lateral release.
- a secondary object of the invention is to provide a support plate whose manufacture is relatively simple. This object is achieved according to the invention by making the lateral zones by overmolding on the central zone.
- FIG. 1 shows, by way of illustration of the invention, a support plate associated with a front binding element for downhill skiing.
- Figure 2 shows in section through a vertical and transverse plane a support plate according to a non-limiting implementation of the invention.
- FIG. 3 illustrates the operation of the support plate of FIG. 2.
- Figure 4 shows an alternative embodiment
- FIGS 5 to 8 show other alternative embodiments.
- FIG. 1 represents a front fixing element 1.
- This element is of a known type and will not be described in detail. It has a shoe retaining jaw 2 carried by a body 3. The body is mounted on a base 4 which is intended to be secured to the ski. The base is extended rearward by a support plate 5 on which the shoe sole comes to rest. Generally, the backing plate is located a little behind the jaw, and it is a standardized area of the front of the shoe sole which rests on it.
- Figures 2 and 3 show a cross section of the support plate 5 according to a first embodiment of the invention.
- dashed line 6 the shoe sole.
- the support plate has three zones juxtaposed in a transverse direction, that is to say a central zone 7 bordered by two lateral zones 8 and 9.
- the middle zone 7 is here located towards the middle of the width of the shoe.
- Each lateral zone extends from one side of the central zone to the extreme edge of the support plate.
- the middle zone is formed by a rod of rigid material.
- the two lateral zones are made of an elastically deformable material.
- the three zones are full, that is to say that they do not leave an opening or void where snow and dirt could penetrate.
- the width of the median zone and the rigidity of the material are chosen so that the median zone is able to support the weight of the skier which is transmitted at this level by the shoe sole.
- the middle zone can have a substantially convex upper surface.
- the bar is oriented in the longitudinal direction defined by the fixing element. It can however be slightly inclined with respect to this direction.
- its lateral flanks 7a, 7b may be parallel or else convergent or divergent.
- the upper surface of the bar on which the shoe rests can be flat or curved.
- the hardness of the material of the lateral zones is chosen so that the zone in question collapses under the effect of a stress in lateral twisting of the shoe. This is illustrated in Figure 3.
- the hardness of the material of the lateral zones can be identical or different for the two zones.
- the shoe rocks around its central part which is supported by the middle zone of the support plate, and its part towards the outside is lowered.
- the rounded shape of the median bar 7 facilitates the tilting of the shoe, and in any case avoids a tilting around a sharp edge.
- the median and lateral zones are covered with a film of anti-friction material 10, for example polytetrafluoroethylene.
- This plate forms a kind of flexible skin on the upper surface of the support plate.
- the median and lateral zones of the wafer are carried by a base 11 which has lateral flanges 12 rising along the edges of the lateral zones over part of their thickness. These edges prevent in particular a creep of the deformable material towards the outside during the collapse of a lateral zone.
- the median bar and material of the lateral zones are compatible, that is to say that the material of the lateral zones is molded onto the rod 7 of the median zone, and the anti-friction plate is assembled during the vulcanization or polymerization of the material of the lateral zones.
- the median bar is made of a material known under the trade name "Delrin”, or of polyamide loaded with glass fibers, for example a polyamide known under the trade name "Rilsan”, and the lateral zones are made of rubber thermosetting.
- FIG. 4 illustrates an alternative embodiment according to which the median zone is produced according to a bar 13 of elastically deformable material, of hardness greater however than the hardness of the lateral zones 14 and 15.
- the material of the median bar can also have damping characteristics.
- the support plate has relative flexibility in a vertical direction, and where appropriate vertical damping properties.
- the material of the central bar 13 and that of the lateral zones 14 and 15 are compatible, that is to say that the lateral zones are formed by overmolding on the central bar.
- the middle zone and the two lateral zones are formed in two stages by two successive moldings or injections.
- the middle bar is made of thermosetting rubber of high hardness
- the lateral zones are made of thermosetting rubber of lower hardness.
- FIG. 5 represents an alternative embodiment according to which the bar 16 which forms the middle zone is also curved on its lower surface. The collapse of a lateral zone in this case causes the bar to pivot on itself over a small amplitude.
- FIG. 6 represents another variant according to which the median bar 18 is extended continuously as far as one of the edges of the support plate. On the other side is a relatively less hard side area 19 than the bar 18.
- Figure 7 illustrates an alternative embodiment.
- the median bar 21 is substantially wider, and it occupies an off-center position relative to the median longitudinal axis of the fixing element.
- the bar 21 is offset towards the inside of the foot.
- the lateral zone 23 is therefore narrower than the other lateral zone 22.
- the tilting of the foot outwards is easier than inwards.
- the bar 21 may have an inclined upper surface.
- Figure 8 shows in cross section a support plate according to an alternative embodiment of the invention.
- the base 25 and the central zone 26 are in one piece.
- the base has on each lateral edge a flange 27, 28, which rises over part of the height of the support plate.
- the flanges 27, 28 have in their upper part a fold 29, 30, which extends inwards.
- a lateral zone 27, 28, occupied by two blocks of elastically deformable material On each side of the central zone 26 is a lateral zone 27, 28, occupied by two blocks of elastically deformable material.
- This material is for example a thermosetting rubber.
- These blocks are for example placed on the bottom of the base. They can also be assembled to the base by gluing or mechanical means.
- the support plate has in its upper part a plate 32 which covers the different zones.
- the plate 32 has flanks 33 and 34 which descend and which engage under the folds 29 and 30.
- the flanks ensure the assembly of the plate to the support.
- the plate is made of a flexible material. Preferably, it has in the region of the central zone 26 thin fold lines 36 which are oriented longitudinally.
- a film of anti-friction material 40 is assembled to the upper surface of the wafer, by any suitable means, for example by gluing.
- This film deforms with the bending of the wafer.
- the device which has just been described can be associated with any front or rear support device for a shoe, in particular with a feeler or a pedal for actuating a mechanism, for example a compensation mechanism.
- the film of anti-friction material could be replaced by profiles oriented longitudinally or transversely.
