Description

Dispositif interface entre un ski et des éléments de retenue d'une chaussure sur le ski et ski ainsi équipé Interface device between a ski and elements for retaining a boot on the ski and ski thus equipped
L'invention concerne un dispositif interface entre un ski alpin et les éléments de retenue d'une chaussure de ski. Elle concerne également un ski équipé du dispositif interface.The invention relates to an interface device between an alpine ski and the retaining elements of a ski boot. It also relates to a ski equipped with the interface device.
Les dispositifs interfaces sont utilisés de façon usuelle dans le but de relever la chaussure au-dessus du ski et par ailleurs d'influer sur certains paramètres mécaniques du ski, dans le but de modifier le comportement du ski sur la neige.Interface devices are used in the usual way for the purpose of raising the boot above the ski and moreover of influencing certain mechanical parameters of the ski, with the aim of modifying the behavior of the ski on snow.
Par exemple, la demande de brevet publiée sous le numéro WO 83/03360 décrit une plaque surélevée par rapport à la surface supérieure du ski. La plaque supporte les deux éléments de retenue de la chaussure. L'une de ses extrémités est reliée solidairement au ski, l'autre extrémité est libre, et des blocs de matériau élastiquement déformables opposent une résistance progressive à son déplacement au cours des flexions de ski.For example, the patent application published under the number WO 83/03360 describes a raised plate relative to the upper surface of the ski. The plate supports the two retaining elements of the shoe. One of its ends is integrally connected to the ski, the other end is free, and blocks of elastically deformable material oppose progressive resistance to its movement during ski bending.
Ce dispositif donne de bons résultats. Toutefois, l'influence qu'il exerce sur le ski varie en intensité avec la flexion du ski, mais pas en nature. C'est-à-dire que le dispositif raidit certaines zones du ski de façon variable, sans déplacer la zone du ski où il exerce son action, selon la flexion du ski.This device gives good results. However, the influence it exerts on skiing varies in intensity with the flexion of the ski, but not in nature. That is to say that the device stiffens certain areas of the ski in a variable manner, without displacing the area of the ski where it exerts its action, according to the flexing of the ski.
On connaît par ailleurs d'après la demande de brevet publiée sous le numéro EP 599 041 un dispositif interface où les deux éléments de retenue sont montés sur des supports distincts. L'élément arrière est monté sur une plaque dont l'extrémité arrière présente une liberté limitée de glissement par rapport à une butée solidaire du ski, et où l'extrémité avant de la plaque s ' étend en avant du support avant et vient en appui contre lui sous l'effet de la poussée du recul. En flexion de ski, la poussée du recul est ramenée vers le support avant tant que l'extrémité arrière de la plaque est libre de coulisser. Au-delà d'une amplitude de flexion déterminée, 1 ' extrémité arrière de la plaque arrive contre une butée solidaire du ski qui reprend les efforts dus à la poussée du recul et les fait transiter par le ski. Ce dispositif donne également de bons résultats, mais les zones du ski influencées par son action ne sont pas optimisées . En outre, son fonctionnement est peu progressif.Furthermore, from the patent application published under the number EP 599 041, an interface device is known in which the two retaining elements are mounted on separate supports. The rear element is mounted on a plate whose rear end has a limited freedom of sliding relative to a stop integral with the ski, and where the front end of the plate extends in front of the front support and comes to bear against him under the effect of the push back. In ski flexion, the backward thrust is brought back to the front support as long as the rear end of the plate is free to slide. Beyond a determined flexion amplitude, the rear end of the plate arrives against a stop integral with the ski which takes up the forces due to the push of the recoil and makes them pass through the ski. This device also gives good results, but the ski areas influenced by its action are not optimized. In addition, its operation is not very progressive.
L'invention a pour but d'améliorer les performances de ce type d'interface. Pour cela, elle propose un dispositif amélioré qui optimise au cours de la flexion du ski les zones du ski dont les caractéristiques mécaniques sont modifiées, et présente un mode de fonctionnement très progressif avec la flexion du ski .The invention aims to improve the performance of this type of interface. For this, it offers an improved device which optimizes during the flexing of the ski the areas of the ski whose mechanical characteristics are modified, and has a very progressive operating mode with the flexing of the ski.
Un autre but de 1 ' invention est de proposer un dispositif interface qui améliore la conduite du ski notamment en entrée et en sortie de virage.Another object of the invention is to provide an interface device which improves the handling of the ski, in particular when entering and exiting corners.
Selon l'invention, le dispositif interface entre un ski et des éléments de retenue d'une chaussure sur le ski comprend une platine avant avec une zone de montage prévue pour 1 ' élément de retenue avant, une platine arrière avec une zone de montage prévue pour un élément de retenue arrière, les deux platines étant distinctes l'une de l'autre, et étant situées sensiblement dans le prolongement l'une de l'autre selon une direction longitudinale dans une position de repos correspondant à une absence de flexion du ski, et les zones de montages définissant des surfaces sensiblement horizontales. Le dispositif est caractérisé par le fait qu'il comprend un tourillon horizontal et transversal prévu pour être porté par le ski, que le tourillon est situé entre les deux platines, qu'au moins l'une des platines est reliée au tourillon avec un degré de liberté en rotation et un degré de liberté en translation sur une amplitude limitée, qu'une butée limite la liberté en translation de ladite platine dans le sens d'un éloignement relatif des deux platines, qu'une face d'appui de ladite platine est en appui sans effort ou avec un très léger jeu contre une contre-face d'une cale prévue pour être reliée solidairement au ski dans le sens d'un éloignement relatif des deux platines, dans la position de repos du dispositif.According to the invention, the interface device between a ski and elements for retaining a boot on the ski comprises a front plate with a mounting area provided for the front retaining element, a rear plate with a mounting area provided for a rear retaining element, the two plates being distinct from each other, and being situated substantially in the extension of one another in a longitudinal direction in a rest position corresponding to an absence of bending of the ski, and the mounting areas defining substantially horizontal surfaces. The device is characterized by the fact that it comprises a horizontal and transverse journal designed to be carried by the ski, that the journal is located between the two plates, that at least one of the plates is connected to the journal with a degree of freedom in rotation and a degree of freedom in translation over a limited amplitude, that a stop limits the freedom in translation of said plate in the direction of a relative distance from the two plates, that a bearing face of said plate is supported effortlessly or with a very slight clearance against the face of a wedge intended to be integrally connected to the ski in the direction of a relative distance from the two plates, in the rest position of the device.

Le ski porte dans sa zone centrale un tourillon horizontal et transversal, que le tourillon est situé entre les deux platines, qu'au moins l'une des platines est reliée au tourillon avec un degré de liberté en rotation et un degré de liberté en translation sur une amplitude limitée, qu'une butée limite la liberté en translation de ladite platine dans le sens d'un éloignement relatif des deux platines, qu'une face d'appui de ladite platine est en appui sans effort ou avec un très léger jeu contre une contre-face d'une cale reliée solidairement au ski dans le sens d'un éloignement relatif des deux platines, dans la position de repos du dispositif.The invention also relates to a ski intended for alpine skiing, equipped with an interface device, the device comprising a front plate with a mounting zone provided for the front retaining element, a rear plate with a mounting zone planned for an element of rear restraint, the two plates being distinct from each other, and being situated substantially in the extension of one another in a longitudinal direction in a rest position corresponding to an absence of flexion of the ski, and the mounting areas defining substantially horizontal surfaces.

La figure 1 montre la partie centrale 1 d'un ski qui est surmontée d'un dispositif interface 2. Le dispositif interface 2 comprend une platine avant 3 associée à un élément de retenue avant 4 et une platine arrière 5 associée à un élément de retenue arrière 6.FIG. 1 shows the central part 1 of a ski which is surmounted by an interface device 2. The interface device 2 comprises a front plate 3 associated with a front retaining element 4 and a rear plate 5 associated with a rear retaining element 6.
Les éléments de retenue avant et arrière sont de tout type approprié et ne seront pas décrits en détail. Ils sont prévus pour retenir de façon libérable les extrémités avant et arrière d'une chaussure de ski. De façon usuelle, le corps 7 de l'élément de retenue arrière 6 est monté coulissant le long d'une glissière longitudinale, et il est rappelé vers l'avant par un ressort que l'on nomme de façon courante ressort de recul. Ce ressort est schématisé en 8 dans les figures 1 et 3.The front and rear retainers are of any suitable type and will not be described in detail. They are designed to releasably retain the front and rear ends of a ski boot. Usually, the body 7 of the rear retaining element 6 is slidably mounted along a longitudinal slide, and it is biased towards the front by a spring which is commonly called recoil spring. This spring is shown diagrammatically at 8 in FIGS. 1 and 3.
La platine avant 3 se présente comme une plaque dont la surface supérieure possède une zone de montage 3a qui est prévue pour recevoir l'élément de retenue avant, y compris la plaque 10 d'appui de la chaussure. De même, la platine arrière 5 a une zone de montage 5a prévue pour recevoir 1 ' élément de retenue arrière, y compris la plaque d'appui 11 de l'arrière de la chaussure.The front plate 3 is presented as a plate, the upper surface of which has a mounting zone 3a which is designed to receive the front retaining element, including the shoe support plate. Likewise, the rear plate 5 has a mounting zone 5a designed to receive the rear retaining element, including the support plate 11 from the rear of the shoe.
La platine avant présente vers 1 ' arrière deux bras 12 et 13 de liaison qui sont reliés au ski au moyen d'un tourillon transversal 16 porté par le ski. De préférence, la platine arrière 5 présente également deux bras 14 et 15 orientés vers l'avant qui sont reliés au même tourillon 16, si bien que les deux platines 3 et 5 sont reliées ensemble au niveau du tourillon qui donne à la platine 3 un degré de liberté en rotation sur une amplitude limitée relativement à la platine 5.The front plate presents towards the rear two link arms 12 and 13 which are connected to the ski by means of a transverse journal 16 carried by the ski. Preferably, the rear plate 5 also has two arms 14 and 15 oriented towards the front which are connected to the same pin 16, so that the two plates 3 and 5 are connected together at the pin which gives the plate 3 a degree of freedom in rotation over a limited amplitude relative to the plate 5.
Selon le mode de réalisation illustré, le ski présente deux décrochements latéraux 18 et 19, ainsi qu'une bosse transversale 20 qui augmente son épaisseur localement et de façon progressive. Un insert 21 est logé dans la structure du ski au niveau de la bosse 20. Par exemple la structure du ski est percée puis 1 ' insert est mis en place, ou bien 1 ' insert est intégré dans la structure du ski au moment de sa fabrication. De préférence dans ce dernier cas, 1 ' insert est placé en appui sous la couche de renfort extérieure du ski .According to the illustrated embodiment, the ski has two lateral recesses 18 and 19, as well as a transverse hump 20 which increases its thickness locally and gradually. An insert 21 is housed in the structure of the ski at the level of the hump 20. For example the structure of the ski is pierced then the insert is put in place, or else the insert is integrated into the structure of the ski at the time of its manufacturing. Preferably in the latter case, the insert is placed in abutment under the outer reinforcing layer of the ski.
Les bras 12 à 15 présentent à leur extrémité un aileron qui descend le long des flancs latéraux du ski. Les ailerons se logent deux à deux dans les décrochements 18 et 19. Le tourillon traverse à la fois des perçages réalisés dans chacun des ailerons et 1 ' insert 21. Le tourillon est par exemple formé par un ensemble comprenant une vis vissée dans une vis douille, c'est-à-dire une vis avec un tube taraudé intérieurement.The arms 12 to 15 have at their end a fin which descends along the lateral flanks of the ski. The fins are housed two by two in the recesses 18 and 19. The pin passes through both holes made in each fins and one insert 21. The journal is for example formed by an assembly comprising a screw screwed into a socket screw, that is to say a screw with an internally threaded tube.
Naturellement ce mode de construction n'est pas limitatif, et d'autres constructions pourraient convenir. Par exemple, 1 ' insert pourrait être un tube taraudé et le tourillon pourrait être formé par deux vis vissées à chaque bout de 1 ' insert . On pourrait également assurer la liaison entre les platines et le ski au moyen de deux vis du même type que celles utilisées pour l'assemblage des éléments de retenue, les deux vis étant vissées directement dans la structure du ski, dans l'alignement l'une de l'autre, en laissant un jeu de fonctionnement pour la rotation des platines .Of course, this method of construction is not limiting, and other constructions could be suitable. For example, the insert could be a threaded tube and the journal could be formed by two screws screwed at each end of the insert. One could also ensure the connection between the plates and the ski by means of two screws of the same type as those used for the assembly of the retaining elements, the two screws being screwed directly into the structure of the ski, in alignment with the one from the other, leaving a working clearance for the rotation of the plates.
En ce qui concerne la liaison entre les platines et le ski, on pourrait aussi adopter d'autres modes de construction qui ne nécessitent pas que le ski présente une bosse transversale. Par exemple, comme le montre la figure 5, le ski pourrait présenter vers le milieu de sa zone centrale un berceau 25 relié solidairement au ski par des vis, avec un bloc central 26 pourvu d'un perçage transversal 27 pour le tourillon. D'autres constructions pourraient également convenir.With regard to the connection between the plates and the ski, other construction methods could also be adopted which do not require the ski to have a transverse bump. For example, as shown in FIG. 5, the ski could present towards the middle of its central zone a cradle 25 connected integrally to the ski by screws, with a central block 26 provided with a transverse bore 27 for the journal. Other constructions could also be suitable.
Les deux platines sont maintenues surélevées par rapport à la surface supérieure du ski au niveau de la liaison avec le tourillon et par deux coussins 28, 29 situés entre les platines et le ski. Les coussins sont par exemple formés par une couche en élastomère. Ces coussins agissent comme des filtres qui amortissent les vibrations du ski.The two plates are kept raised relative to the upper surface of the ski at the connection with the trunnion and by two cushions 28, 29 located between the plates and the ski. The cushions are for example formed by an elastomer layer. These cushions act as filters which dampen the vibrations of the ski.
Au repos les deux platines sont sensiblement dans l'alignement l'une de l'autre, leur surface de montage respective définissant un plan sensiblement horizontal. Le tourillon de liaison des deux platines au ski permet aux deux platines de pivoter l'une par rapport à l'autre et relativement au ski de façon à suivre la flexion du ski .At rest the two plates are substantially in alignment with each other, their respective mounting surface defining a substantially horizontal plane. The connecting pin of the two plates to the ski allows the two plates to pivot relative to each other and relative to the ski so as to follow the flexing of the ski.
Ce mode de liaison est avantageux car il libère le ski en flexion. Il améliore l'enroulement du ski dans les phases d'entrée et de sortie de virage.This connection method is advantageous because it frees the ski in flexion. It improves the winding of the ski during the entry and exit phases.
Selon l'invention, l'une au moins des deux platines est reliée au ski avec un degré de liberté en translation sur une amplitude limitée, en plus de son degré de liberté en rotation. Dans le mode de réalisation illustré, les ailerons des bras 12 et 13 de la platine avant 3 sont percés d'un orifice oblong 30, 31 dont la grande dimension est orientée selon une direction longitudinale. Ainsi, la platine 3 est susceptible de se déplacer en translation relativement au tourillon 16 selon une direction longitudinale. En présence de la chaussure, la réaction à la poussée du ressort de recul 8 tend à éloigner les deux platines l'une de l'autre jusqu'à une position de butée visible en figure 1 où le tourillon 16 est en appui contre la partie arrière 30a, 31a des trous oblongs 30 et 31.According to the invention, at least one of the two plates is connected to the ski with a degree of freedom in translation over a limited amplitude, in addition to its degree of freedom in rotation. In the illustrated embodiment, the fins of the arms 12 and 13 of the front plate 3 are pierced with an oblong orifice 30, 31 whose large dimension is oriented in a longitudinal direction. Thus, the plate 3 is capable of moving in translation relative to the pin 16 in a longitudinal direction. In the presence of the shoe, the reaction to the thrust of the recoil spring 8 tends to move the two plates apart from one another to a stop position visible in FIG. 1 where the pin 16 is in abutment against the part rear 30a, 31a of the oblong holes 30 and 31.
En variante, la platine arrière pourrait présenter des trous oblongs à la place de la platine avant, ou bien les deux platines pourraient présenter des trous oblongs .Alternatively, the rear plate could have oblong holes in place of the front plate, or the two plates could have oblong holes.
D'autres constructions pourraient également convenir pour réaliser le mouvement de translation relatif entre les deux platines, avec une position de butée des deux platines dans le sens d'un éloignement relatif.Other constructions could also be suitable for carrying out the relative translational movement between the two plates, with an abutment position of the two plates in the direction of a relative distance.
En présence de la chaussure, et en l'absence de flexion du ski, les deux platines étant en butée l'une relativement à l'autre par l'intermédiaire du tourillon 16, la réaction à la poussée du recul est reprise par les platines sans transiter par le ski .In the presence of the boot, and in the absence of flexing of the ski, the two plates being in abutment relative to one another by means of the pin 16, the reaction to the push of the recoil is taken up by the plates without going through the ski.
Selon l'invention, au moins la platine qui est reliée au tourillon avec jeu coopère avec une cale reliée solidairement au ski, avec la flexion du ski. De préférence, chacune des deux platines coopère avec une cale.According to the invention, at least the plate which is connected to the journal with play cooperates with a wedge connected integrally to the ski, with the flexing of the ski. Preferably, each of the two plates cooperates with a block.
Ainsi, en se référant à la figure 1, la platine avant 3 se prolonge sur l'avant par un embout 33 avec à son extrémité une face d'appui 34 inclinée d'avant en arrière et de bas en haut. L'inclinaison de la face d'appui 34 est de l'ordre de 45 degrés .Thus, with reference to FIG. 1, the front plate 3 is extended on the front by a nozzle 33 with at its end a bearing face 34 inclined from front to back and from bottom to top. The inclination of the bearing face 34 is of the order of 45 degrees.
Une cale 35 est assemblée solidairement au ski, par exemple au moyen de vis ou par une technique de collage ou de soudage. La cale 35 a une contre-face d'appui 36 de même inclinaison sensiblement que la face 34. En position de repos du ski, c'est-à-dire en l'absence de flexion, la contre-face 36 est en appui sans effort contre la face 34, ou bien il existe un très léger jeu entre les deux faces. Eventuellement un bloc compressible pourrait être intercalé entre les deux faces d'appui 34 et 36.A wedge 35 is assembled integrally with the ski, for example by means of screws or by a bonding or welding technique. The wedge 35 has a support counter-face 36 of the same inclination substantially as the face 34. In the ski's rest position, that is to say in the absence of bending, the counter-face 36 is in support effortlessly against the face 34, or there is a very slight clearance between the two faces. Possibly a block compressible could be interposed between the two bearing faces 34 and 36.
De préférence, comme cela est visible dans la figure 2, la cale 35 chevauche l'embout 33, et elle est évidée de façon à permettre le mouvement longitudinal de l'embout 33 et à entraver son mouvement latéral et vertical vers le haut .Preferably, as can be seen in FIG. 2, the shim 35 overlaps the end piece 33, and it is hollowed out so as to allow the longitudinal movement of the end piece 33 and to hinder its lateral and vertical movement upwards.
Selon le mode de réalisation de la figure 1, la platine arrière présente le même montage que la platine avant, avec un embout 38, une face d'appui 39, une cale 40 reliée solidairement au ski, et une contre-face d'appui 41.According to the embodiment of Figure 1, the rear plate has the same mounting as the front plate, with a tip 38, a bearing face 39, a wedge 40 connected integrally to the ski, and a supporting face 41.
Comme dans le cas précédent, au repos, les faces 39 et 41 sont en appui sans effort, où il existe un léger jeu entre elles . Un bloc de matériau élastomère peut également être intercalé entre les deux faces 39 et 41.As in the previous case, at rest, the faces 39 and 41 are supported effortlessly, where there is a slight clearance between them. A block of elastomeric material can also be interposed between the two faces 39 and 41.
Le dispositif qui vient d'être décrit fonctionne de la façon suivante.The device which has just been described operates in the following manner.
Lorsque le ski fléchit, sur l'avant, les deux faces 34 et 36 glissent l'une contre l'autre, ce qui provoque la compression ou l'écrasement du coussin 28. Du fait de la coopération des faces 34 et 36, la platine 3 se trouve plaquée contre la surface supérieure du ski, ce qui améliore sa liaison avec le ski, et la transmission des efforts de conduite donnés par le skieur. Lorsque le coussin 28 est totalement comprimé et que le ski continue à fléchir étant donné la position surélevée de la platine au-dessus du ski, la platine recule relativement au ski au niveau de ses ailerons arrière, c'est-à-dire que les trous oblongs 30 et 31 quittent leur appui contre le tourillon 16.When the ski flexes, on the front, the two faces 34 and 36 slide one against the other, which causes compression or crushing of the cushion 28. Due to the cooperation of the faces 34 and 36, the plate 3 is pressed against the upper surface of the ski, which improves its connection with the ski, and the transmission of the driving forces given by the skier. When the cushion 28 is fully compressed and the ski continues to flex due to the raised position of the plate above the ski, the plate moves back relatively to the ski at its rear fins, that is to say that the oblong holes 30 and 31 leave their support against the pin 16.
Comme on peut le voir dans la figure 3 , les deux platines suivent la flexion du ski et pivotent relativement au tourillon 16 l'une par rapport à l'autre et aussi l'une et l'autre relativement au ski .As can be seen in Figure 3, the two plates follow the flexion of the ski and pivot relative to the pin 16 relative to each other and also both relative to the ski.
Comme la platine avant 3 a quitté son appui contre le tourillon 16, les efforts dus à la poussée du recul sont désormais repris par la cale avant 35. Parallèlement à cela, du fait de la flexion du ski, le corps 7 de l'élément de retenue arrière recule davantage, et la poussée du recul augmente. Cette poussée étant transmise au ski, la raideur élastique du ski augmente, le ski tend davantage à se détendre pour revenir à sa position de repos. Ceci améliore la relance du ski en fin de virage .As the front plate 3 has left its support against the pin 16, the forces due to the pushing of the recoil are now taken up by the front block 35. At the same time, due to the bending of the ski, the body 7 of the element rear restraint recedes further, and the recoil boost increases. This thrust being transmitted to the ski, the elastic stiffness of the ski increases, the ski tends more to relax to return to its rest position. This improves the revival of the ski at the end of the turn.
Lorsque la flexion du ski cesse, la platine avant reprend progressivement sa position de repos par rapport à la cale avant et par rapport au tourillon 16, et la poussée du recul est ramenée progressivement au tourillon 16.When the flexion of the ski ceases, the front plate progressively returns to its rest position relative to the front wedge and relative to the pin 16, and the thrust of the recoil is gradually brought back to the pin 16.
Au niveau de l'arrière, la flexion du ski provoque également la coopération des faces d'appui 39 et 41. Le coussin 29 est comprimé jusqu'à l'écrasement, ce qui rend plus directe la liaison entre la platine et le ski. En outre, la poussée du recul est transférée progressivement depuis le tourillon 16 vers la poutre du ski, en arrière du tourillon.At the rear, the flexing of the ski also causes the cooperation of the bearing faces 39 and 41. The cushion 29 is compressed until crushing, which makes the connection between the plate and the ski more direct. In addition, the push back is gradually transferred from the pin 16 to the ski beam, behind the pin.
Selon 1 ' invention, le montage de la platine arrière avec la cale et les faces est un mode de réalisation préféré mais non limitatif pour l'invention. La platine arrière pourrait en effet être reliée solidairement au ski, au moins dans sa partie avant, c'est-à-dire à proximité du tourillon. Ce qui est important, c'est que la platine avant, ou plutôt l'une des deux platines, présente par rapport au tourillon un degré de liberté en rotation et un degré de liberté en translation sur une amplitude limitée, de façon à ce que la poussée du recul soit transférée progressivement depuis le tourillon 16, c'est-à-dire depuis la zone d'ancrage de l'autre platine vers la cale, c ' est-à-dire vers le ski .1 according to the invention, the mounting of the rear plate with the wedge and the faces is a preferred embodiment but not limiting for the invention. The rear plate could indeed be integrally connected to the ski, at least in its front part, that is to say near the journal. What is important is that the front plate, or rather one of the two plates, has with respect to the journal a degree of freedom in rotation and a degree of freedom in translation over a limited amplitude, so that the push back is gradually transferred from the pin 16, that is to say from the anchoring zone of the other plate towards the wedge, that is to say towards the ski.
Les figures 6 et 7 représentent un mode de réalisation préféré du dispositif interface qui vient d'être décrit.Figures 6 and 7 show a preferred embodiment of the interface device which has just been described.
Dans la figure 6 qui représente la platine avant, la platine comprend une plaque de base 43 avec une zone de montage 43a prévue pour le socle 44 de l'élément de retenue avant. La plaque de base est en tout matériau approprié, par exemple en une résine armée de fibres.In Figure 6 which shows the front plate, the plate comprises a base plate 43 with a mounting area 43a provided for the base 44 of the front retaining element. The base plate is made of any suitable material, for example a fiber-reinforced resin.
La plaque de base est bordée latéralement par deux longerons 45, 46 qui sont rapportés et qui sont assemblés par des vis. Les longerons sont par exemple réalisés en métal. Les longerons sont prolongés vers l'arrière par des bras 47, 48 qui se terminent par des ailerons inférieurs avec leur trou oblong 49, 50. Le tourillon est formé par une vis 51 et une vis douille 52. La plaque de base a sur l'avant un embout 53 avec sa face d'appui inclinée 54 qui est prévue pour être engagée dans 1 ' évidement non visible de la cale avant 55. La cale est assemblée au ski par exemple par soudage.The base plate is bordered laterally by two longitudinal members 45, 46 which are attached and which are assembled by screws. The side members are for example made of metal. The longitudinal members are extended rearwards by arms 47, 48 which end in lower fins with their oblong hole 49, 50. The journal is formed by a screw 51 and a socket screw 52. The base plate has on the front an end piece 53 with its inclined bearing face 54 which is designed to be engaged in one non-visible recess of the front wedge 55. The wedge is assembled to the ski for example by welding.
Enfin le coussin 56 est situé entre la plaque de base et la surface supérieure du ski.Finally the cushion 56 is located between the base plate and the upper surface of the ski.
Sur l'arrière, la platine comprend une plaque de base 58 avec une zone de montage 58a prévue pour la glissière 59 de l'élément de retenue arrière. La plaque de base est bordée latéralement par deux longerons 61, 62, qui se prolongent vers l'avant par deux bras 63, 64, avec à leur extrémité un aileron percé d'un orifice 65, 66 de liaison avec le tourillon.On the rear, the plate comprises a base plate 58 with a mounting area 58a provided for the slide 59 of the rear retaining element. The base plate is bordered laterally by two longitudinal members 61, 62, which extend forwardly by two arms 63, 64, with at their end a fin pierced with an orifice 65, 66 for connection with the journal.
Un coussin 67 est placé sous la plaque de base 58, entre la plaque de base et la surface supérieure du ski .A cushion 67 is placed under the base plate 58, between the base plate and the upper surface of the ski.
Vers l'arrière, la plaque de base a un embout 69 avec une face d'appui inclinée 70 qui pénètre dans 1 ' évidement 71 de la cale 72. La cale 72 est assemblée au ski par exemple par soudage .Towards the rear, the base plate has a tip 69 with an inclined bearing face 70 which penetrates into the recess 71 of the wedge 72. The wedge 72 is assembled to the ski, for example by welding.
La figure 8 est relative à une variante de mise en oeuvre de 1 ' invention .Figure 8 relates to an alternative embodiment of one invention.
Au lieu d'être situées aux extrémités avant et arrière des platines, les cales 75 et 76 avec leur face inclinée 77 et 78 sont situées à 1 ' intérieur du périmètre des platines avant et arrière 79, 80.Instead of being situated at the front and rear ends of the plates, the wedges 75 and 76 with their inclined face 77 and 78 are situated inside the perimeter of the front and rear plates 79, 80.
Les cales 75 et 76 sont logées dans des évidements centraux 81 et 82 des platines, et leurs faces d'appui coopèrent avec des faces d'appui complémentaires 83 et 84 des évidements 81 et 82. Au repos, les faces d'appui reposent les unes sur les autres sans effort, ou bien il existe entre elles un très léger jeu.The wedges 75 and 76 are housed in central recesses 81 and 82 of the plates, and their bearing faces cooperate with complementary bearing faces 83 and 84 of the recesses 81 and 82. At rest, the bearing faces rest the effortlessly, or there is a very slight play between them.
Les deux platines 79 et 80 sont surélevées par rapport à la surface supérieure du ski, et elles reposent sur des coussins 85, 86. Elles sont reliées entre elles par un tourillon 87 horizontal et transversal qui traverse la structure du ski. Le tourillon 87 traverse un orifice oblong 88 de la platine avant 79.The two plates 79 and 80 are raised relative to the upper surface of the ski, and they rest on cushions 85, 86. They are linked together by a horizontal and transverse pin 87 which crosses the structure of the ski. The pin 87 passes through an oblong orifice 88 of the front plate 79.
Cette variante fonctionne sensiblement de la même façon que le mode de réalisation précédent. Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de 1 ' invention sans pour autant sortir du cadre de celle-ci .This variant works substantially in the same way as the previous embodiment. Naturally, the present description is given for information only, and other implementations of the invention could be adopted without departing from the scope thereof.
En particulier, tel que cela a déjà été évoqué précédemment, la platine qui est mobile en rotation et en translation par rapport au tourillon n'est pas nécessairement la platine avant. La platine arrière pourrait également être mobile en translation par rapport au tourillon ou bien les deux platines pourraient être mobiles en translation. Dans le cas où l'une des platines n'est pas mobile en translation par rapport au tourillon, ladite platine pourrait être reliée solidairement au ski, tout au moins dans sa zone située à proximité du tourillon au lieu d'être accrochée au tourillon. Egalement, au lieu de coopérer ensemble par des faces d'appui inclinées, les platines et les cales pourraient coopérer par des faces verticales formant des butées franches. Dans ce cas, on perdrait l'effet de placage de la platine contre la surface supérieure du ski qui se produit avec la flexion du ski. In particular, as has already been mentioned previously, the plate which is movable in rotation and in translation relative to the pin is not necessarily the front plate. The rear plate could also be movable in translation relative to the pin or the two plates could be movable in translation. In the case where one of the plates is not movable in translation relative to the journal, said plate could be integrally connected to the ski, at least in its zone located near the journal instead of being attached to the journal. Also, instead of cooperating together by inclined bearing faces, the plates and the shims could cooperate by vertical faces forming frank stops. In this case, we would lose the effect of plating the plate against the upper surface of the ski which occurs with the bending of the ski.
