Definitions
- the invention relates to a shoe support plate, which is intended to be associated with a front ski binding element.
- a shoe is retained on a ski by a front binding element and a rear binding element. It also rests at its front end on a support plate which is associated with the front fixing element. In its rear part, it also rests on a support associated with the rear fixing element.
- the currently known support plates include a base which has in its upper part a layer of material with a low coefficient of friction, on which the shoe sole rests.
- This layer is for example formed by the upper surface of a polytetrafluoroethylene plate.
- Such a support plate is for example described in French patent no. 2,533,832, as well as French patent no. 2,615,748.
- the first document describes an assembly of the anti-friction plate on a base by gluing, while the second document relates to assembly by mechanical means, such as snap-fastening.
- the anti-friction plate is subjected on the part of the shoe to high stresses, in particular during the engagement of the shoe in the binding, or else during the lateral release of the shoe.
- European patent n ° 404848 describes such a removable support plate.
- the drawback of this device is that the assembly of the support plate to the binding element is carried out by means of the two rear screws for assembling the binding to the ski.
- the exchange of the support plate requires partial unscrewing and then re-screwing of these screws.
- Such an operation deteriorates the attachment of these screws in the ski, and therefore the assembly of the binding on the ski.
- it is the entire base which is changed, and on this subject, it should be noted that if the anti-friction plate can be damaged, the base itself is not damaged most often .
- the assembly of the anti-friction plate on its support is final, that is to say that once assembled, the anti-friction plate cannot be detached from its support without causing its deterioration or that of its support.
- One of the aims of the invention is to provide a support plate whose part which carries the friction plate can be easily interchanged.
- Another object of the invention is to provide a support plate whose exchange does not require the disassembly of the entire base.
- Another object of the invention is to provide a support plate, the base of which can respond to constraints of a totally different nature, in particular with regard to the method of assembling the anti-friction plate, and the mechanical stresses to which the shoe submits the backing plate.
- the support plate associated with a front ski binding element, is intended to support the front part of a boot, having a base extending behind the base of the binding element, and integral with it. ci, an anti-friction plate on which the shoe sole rests, the anti-friction plate being interchangeable.
- This support plate is characterized by the fact that the base comprises a base plate, and a support of the anti-friction plate independent of the base plate, that the anti-friction plate is assembled definitively on the support, and that the support is removably assembled to the base plate by means of mutual interlocking and reversible locking means.
- FIG. 1 shows, in perspective, a front fastening element equipped with a support plate according to a non-limiting mode of implementation of the invention.
- FIG. 2 shows, in exploded view, the main elements which constitute the support plate of Figure 1.
- Figure 3 is a top view of the base plate shown in Figure 2.
- FIG. 4 is a sectional view along AA of the support plate shown in Figure 2.
- FIG. 5 illustrates the disassembly of the support.
- FIG. 6 shows in perspective a front fastening element equipped with a support plate, and illustrates another embodiment of the invention.
- FIG. 7 is a top view of the support plate shown in FIG. 6.
- FIG. 8 is a sectional view through a vertical and longitudinal plane of the support plate of FIG. 7.
- FIG. 1 shows a front fixing element 1, the base 2 of which is intended to be secured to a ski by any suitable means, and for example by means of screws.
- the base 2 is extended rearward by a support plate 3, the main elements of which are a base 4 and a plate made of anti-friction material 5, such as for example a resin plate
- the base 2 is extended rearwards by a support plate 3, the main elements of which are a base 4 and a plate made of anti-friction material 5, such as for example a plate made of fluorinated resin or polytetrafluoroethylene.
- the wafer 5 adheres to the base 4 by any suitable means other than a mechanical joining means, for example, it adheres by bonding using a cyano-acrylate or isocyanate-acrylic adhesive, or else it adheres by a welding process.
- the wafer 5 is assembled on its support definitively, that is to say that it cannot be detached without being damaged or without deteriorating its support.
- the support plate 3 comprises a base plate 6, which is integrally connected to the base 2 of the attachment, as well as a removable support 7.
- the plate base 6 is constituted by a blade of material 8 which folds back on itself and which closes with an elastic bellows 9.
- a base plate is known, and it has, thanks to the bellows 9 and the elasticity of the material which constitutes the blade, a large amplitude of compression in a vertical direction.
- the material which constitutes the blade 8 must therefore necessarily have an aptitude for elastic deformation.
- Such a material can be a metal, or then for example a plastic material known as "DELRIN", which is known for its elasticity, and its memory, that is to say its ability to return to its initial shape. after a deformation.
- DELRIN plastic material known as "DELRIN”
- such a material is not compatible with the assembly by gluing of an anti-friction plate, using a glue of the cyano-acrylate type.
- the support plate 3 also has a support 7 c,.; carries the anti-friction plate 5.
- the support 7 has planar dimensions which allow it to cover the upper part of the base plate 6, at least in its rear region. It also preferably has two lateral flanks 9 which descend on the edges of the base plate 6.
- the support 7 is intended to carry the anti-friction plate 5, it is made of a material compatible with the method of assembling the plate.
- the support 7 is made of a plastic material known under the name "ABS”, and the anti-friction plate is bonded to this support by means of a cyano-acrylate adhesive, or of the isocyanate-acrylic type.
- ABS cyano-acrylate adhesive
- Such a material, known as "ABS” is compatible with bonding where? the anti-friction plate, but this material would not be suitable for producing the base plate 6, since this material does not have the elasticity and memory characteristics required at the level of the base plate 6.
- the support 7 is assembled removably to the support plate 6 by complementary means of mutual interlocking, and reversible locking means.
- the nesting means operate in a generally longitudinal direction
- the fitting means comprise for the support 7 four tabs 10 located under the support, approximately at each of its corners.
- the tabs 10 are extended downwards and forwards by tongues 11 which extend horizontally.
- the fitting means comprise two front recesses 12, and two rear recesses 13, which are located in locations corresponding to the locations of the tabs 10 of the support 7.
- the thickness of the base plate 6, at the level of the recesses 12 and 13, is substantially equal to the height of the cleats 10.
- the nesting of the support on the base plate 6 is effected by presenting the support in such a way that the tabs 10 and their tongues 11 engage in the recesses 12 and 13. Once this engagement has been achieved, the nesting is carried out by a simple movement of the support 7 forward.
- the tabs then constitute a stop for the support 7 for a forward movement, and any lateral movement.
- the tabs constitute, for their part, a stop for a vertical movement upwards.
- the assembly of the support 7 on the base plate 6 is also carried out by locking means.
- These means comprise, for the base plate 6, an elastic tongue 16, oriented towards the front.
- This tongue is intended to cooperate with a stop 18 located under the support 7. When the support 7 is put in place, this stop 18 comes to be positioned just in front of the tongue 16, so that this tongue, taking support in rear of the stopper 18, prevents any movement towards the rear of the support 7.
- the support 7 has just behind this stop 18, and therefore at the level of the tongue 16 an opening 19, through which the blade 20 of a tool such as a screwdriver can be introduced. Through this opening, the blade 20 can therefore access the elastic tongue 16, and press down on this tongue to make it bend, so that the stop 18 escapes from its retention.
- the tongue 16 has in its front part a flange 22.
- the engagement of the tool in the opening 19 causes the elastic tongue 16 to bend, and if the tool is then tilted backwards, by bearing on a flange 22 of the elastic tongue 16, the blade 20 of the tool causes the rearward release of the support 7.
- the support 7 can be easily removed from the plate base 6, and a new support can then be fitted and locked on the base plate.
- FIGS 6 to 10 illustrate another embodiment of the invention.
- the anti-friction plate 25 is assembled definitively on a support 27, and the support 27 is fitted into the base plate 26 in a generally vertical direction.
- the base plate 26 has, in its upper part, a central recess 28 whose dimensions correspond to the dimensions of the support 27.
- the support 27 is engaged in the recess 28 of the base plate in an approximately vertical direction.
- a protruding rim 31 situated on the front edge of the support 27 is engaged under the upper surface of the base plate 26.
- an elastic lip 29 provided with a protruding rim 30 ensures reversible locking of the support 27 in the base plate 26.
- the central recess 28 has, in the region of the lip 29, a transverse cut 34 in which the blade of a tool such as a screwdriver (shown diagrammatically at 32 in FIG. 8) can be inserted to release the lip 29 and the rim 30 and, by a tilting movement of the tool, to extract the support 27 from the recess 28.
- a block of elastically compressible material 33 is placed under the support 27 at the bottom of the recess 28 so that the support comes out to bear on the block 33. Under the action of a vertical thrust of the shoe downwards, the support 27 can compress the block 33 under compression.
- the means for fitting the support 27 into the base plate 26 also constitute means for guiding the support 27 in the base plate 26 for its vertical movement.
- a more or less noticeable damping effect can be obtained from the front support of the shoe.
- FIG. 10 illustrates another alternative embodiment according to which the elastic lip 35 which ensures the reversible locking of the support 27 forms part of the base plate 26.
- the tool is then introduced into the recess of the base plate, between the lip 35 and the support 27 to cause the release of the lip and the extraction of the support.
