Description

La présente invention concerne les raquettes à neige et les skis de randonnée, que l'on utilise pour la progression sur la neige par un mouvement de marche.The present invention relates to snowshoes and touring skis, which are used for progression on snow by a walking movement.

Pour faciliter le mouvement de marche, dans lequel le talon du pied se soulève, les fixations de ski de randonnée, et certaines fixations de raquette à neige, comportent une plaque de fixation articulée autour d'un axe de rotation transversal antérieur, la chaussure de l'utilisateur étant fixée à la plaque par des fixations de type connu.To facilitate the walking movement, in which the heel of the foot lifts, the ski touring bindings, and certain snowshoe bindings, include a fixing plate articulated around an anterior transverse axis of rotation, the boot the user being fixed to the plate by fasteners of known type.

Pour une utilisation en descente, la plaque de fixation articulée de ski est bloquée sur la face supérieure du ski par un système de verrouillage qui retient l'extrémité postérieure de la plaque à proximité de la face supérieure de ski. Le dispositif de verrouillage est généralement un tiroir à glissière, en coulissement longitudinal sur le ski.For downhill use, the articulated ski binding plate is blocked on the upper face of the ski by a locking system which retains the rear end of the plate near the upper ski face. The locking device is generally a slide drawer, sliding longitudinally on the ski.

Certaines raquettes à neige sont également munies d'un dispositif de verrouillage de plaque de fixation, en forme de crochet pivotant sur le corps de raquette selon un axe transversal parallèle à la face supérieure de raquette, et venant s'engager dans une rainure transversale de la plaque de fixation. Ces dispositifs présentent soit une difficulté de manoeuvre au déverrouillage ou au verrouillage lorsque l'encliquetage est rigide, soit une efficacité de verrouillage insuffisante lorsqu'on laisse une souplesse ou un jeu résiduel au verrouillage.Some snowshoes are also fitted with a fastening device locking device, in the form of a hook pivoting on the racket body along a transverse axis parallel to the upper surface of the racket, and coming to engage in a transverse groove of the mounting plate. These devices present either a difficulty in maneuvering when unlocking or locking when the latching is rigid, or an insufficient locking efficiency when flexibility or residual play is left in the locking.

On connaît par ailleurs des cales de montée, que l'on vient fixer de façon amovible soit sur la face supérieure du ski, soit sous la face inférieure de plaque de fixation, au voisinage de l'extrémité postérieure de la plaque de fixation, pour conserver une inclinaison relative de la plaque de fixation lors d'une progression en montée, de façon que le pied de l'utilisateur reste sensiblement horizontal tandis que la raquette à neige ou le ski est inclinée dans le sens de la montée. Ces cales sont toutefois peu commodes d'emploi, notamment pour les opérations d'insertion ou d'enlèvement de la cale, ou pour obtenir un réglage de l'inclinaison.There are also known climbers, which are removably fixed either on the upper face of the ski, or under the underside of the fixing plate, in the vicinity of the rear end of the fixing plate, to maintain a relative inclination of the fixing plate during an uphill progression, so that the user's foot remains substantially horizontal while the snowshoe or the ski is inclined in the direction of ascent. These shims are however inconvenient to use, in particular for the operations of inserting or removing the shim, or for obtaining an adjustment of the inclination.

On connaît également, du document FR-A-2 302 116, une fixation de ski à plaque articulée et à cale verrouillante, la cale comprenant un corps allongé monté pivotant autour d'un axe intermédiaire perpendiculaire à la face supérieure du ski. Le corps présente une forme allongée étroite, comportant une première extrémité à face inclinée destinée à retenir sélectivement l'extrémité arrière également inclinée d'une plaque de fixation, et une seconde extrémité portant une butée élastique sous forme d'un ressort avec une tige rigide amovible. La cale peut être placée en une première position pour verrouiller la plaque par sa première extrémité, une seconde position pivotée à 180° pour former une cale élastique sous la plaque, et une troisième position transversale libérant sélectivement la plaque de fixation. Le corps de cale, tenu par un boulon, serré par un écrou supérieur, glisse en rotation sur une plaque circulaire fixée sur la surface supérieure du ski. On comprend qu'une telle structure de cale ne présente pas une résistance mécanique suffisante, notamment pour supporter des efforts orientés de biais ou latéralement sur le corps en position de cale. En outre, il apparaît que le dispositif décrit dans ce document n'assure pas une bonne efficacité de verrouillage.Also known from document FR-A-2 302 116 is a ski binding with an articulated plate and a locking wedge, the wedge comprising a elongated body mounted to pivot about an intermediate axis perpendicular to the upper face of the ski. The body has a narrow elongated shape, comprising a first end with an inclined face intended to selectively retain the rear end, also inclined, of a fixing plate, and a second end carrying an elastic stop in the form of a spring with a rigid rod. removable. The wedge can be placed in a first position to lock the plate by its first end, a second position pivoted by 180 ° to form an elastic wedge under the plate, and a third transverse position selectively releasing the fixing plate. The wedge body, held by a bolt, tightened by an upper nut, slides in rotation on a circular plate fixed on the upper surface of the ski. It is understood that such a wedge structure does not have sufficient mechanical strength, in particular to withstand forces oriented obliquely or laterally on the body in the wedge position. In addition, it appears that the device described in this document does not provide good locking efficiency.

De même, le document US-A-4 392 666 décrit une fixation de ski à cale verrouillante, le corps de cale étant constitué d'une bande métallique pliée et étroite, qui n'est pas susceptible de présenter une résistance mécanique suffisante pour des efforts obliques ou latéraux en position de cale.Likewise, document US-A-4 392 666 describes a ski binding with locking wedge, the wedge body consisting of a folded and narrow metal strip, which is not likely to have sufficient mechanical strength for oblique or lateral forces in the wedge position.

Le problème proposé par la présente invention est de concevoir une nouvelle structure de cale de montée verrouillante présentant à la fois une excellente efficacité de verrouillage, une très grande facilité de manoeuvre, une grande résistance mécanique, une légèreté compatible avec les conditions d'usage actuelles, et un faible coût de production et d'adaptation. En particulier, la structure de cale de montée doit présenter une résistance mécanique suffisante pouvant supporter des efforts obliques ou latéraux en position de cale, sans déformation ou usure anormales.The problem proposed by the present invention is to design a new locking wedge structure having both excellent locking efficiency, very easy maneuverability, great mechanical strength, lightness compatible with current conditions of use. , and a low production and adaptation cost. In particular, the climb wedge structure must have sufficient mechanical strength which can withstand oblique or lateral forces in the wedge position, without abnormal deformation or wear.

Ces avantages de résistance mécanique doivent être obtenus en particulier pour des cales de montée de raquette à neige, alors que le corps de raquette à neige présente une flexibilité relativement grande, et est généralement réalisé en une matière plastique peu résistante à l'usure. L'invention vise ainsi à réaliser une structure particulière de liaison entre la cale et le corps de raquette ou de ski, procurant les avantages recherchés.These advantages of mechanical resistance must be obtained in particular for climbing blocks for snowshoeing, while the body of snowshoeing has a relatively great flexibility, and is generally made of a plastic material little resistant to wear. The invention thus aims to achieve a particular connection structure between the wedge and the racket or ski body, providing the desired advantages.

Il convient en outre d'éviter que la neige ou la glace perturbent le fonctionnement de la cale, notamment sa rotation.It should also be avoided that snow or ice disturb the functioning of the hold, in particular its rotation.

Pour atteindre ces objets ainsi que d'autres, une raquette à neige ou un ski selon l'invention, est munie d'une fixation de chaussure articulée autour d'un axe de rotation transversal antérieur, et est munie d'une cale de retenue sur la face supérieure de la raquette ou du ski. La cale comprend un corps de cale monté pivotant autour d'un axe intermédiaire perpendiculaire à la face supérieure de raquette ou de ski, le corps de cale étant conformé pour retenir sélectivement à proximité de la face supérieure de raquette ou de ski l'extrémité postérieure de fixation ou de chaussure dans une orientation fonctionnelle de verrouillage du corps, pour libérer sélectivement la fixation et la chaussure dans une orientation fonctionnelle de déverrouillage du corps, et pour former sélectivement appui sous l'extrémité postérieure de fixation ou de chaussure dans une orientation fonctionnelle de calage du corps ; le corps de cale comprend, sur sa face inférieure, au moins une première nervure circulaire, centrée sur l'axe intermédiaire, prenant appui par sa crête sur la face supérieure de raquette ou de ski pour former une base d'appui large du corps de cale reprenant les efforts de flexion du corps à l'écart de l'axe intermédiaire tant dans la direction longitudinale que dans la direction transversale de la raquette ou du ski.To achieve these and other objects, a snowshoe or a ski according to the invention is provided with a shoe binding articulated around an anterior transverse axis of rotation, and is provided with a retaining wedge. on the upper side of the snowshoe or ski. The wedge comprises a wedge body mounted pivoting about an intermediate axis perpendicular to the upper face of the racket or ski, the wedge body being shaped to selectively retain near the upper face of the racquet or ski the rear end. of fixation or shoe in a functional orientation of locking the body, to selectively release the fixation and the shoe in a functional orientation of unlocking the body, and to selectively form support under the posterior end of fixation or shoe in a functional orientation body wedging; the wedge body comprises, on its lower face, at least one first circular rib, centered on the intermediate axis, bearing by its crest on the upper face of snowshoe or ski to form a wide support base of the body of wedge taking up the bending forces of the body away from the intermediate axis both in the longitudinal direction and in the transverse direction of the snowshoe or the ski.

Selon un mode de réalisation avantageux :

  • le corps de cale comprend, sur sa face inférieure, au moins une seconde nervure circulaire intermédiaire, centrée sur l'axe intermédiaire, prenant appui par sa crête sur la face supérieure de raquette ou de ski et séparée de la première nervure circulaire qui l'entoure par une rainure circulaire,
  • la face supérieure de raquette ou de ski porte une nervure de base circulaire, centrée sur l'axe intermédiaire, et conformée pour s'engager à faible jeu dans la rainure circulaire du corps de cale.

  • the upper face of snowshoe or ski carries a circular base rib, centered on the intermediate axis, and shaped to engage with little play in the circular groove of the wedge body.

Dans le cas d'une raquette ou d'un ski dont le corps est réalisé en un matériau relativement tendre, la nervure de base circulaire peut avantageusement être formée d'une bague rapportée sur la surface supérieure de raquette ou de ski, munie d'ergots de positionnement dépassant de son bord inférieur et s'engageant dans des trous correspondants de la face supérieure de raquette ou de ski, la bague et le corps de cale étant réalisés en des matières plastiques présentant des résistances mécaniques identiques ou similaires et présentant de bonnes propriétés anti-usure.In the case of a racket or a ski whose body is made of a relatively soft material, the circular base rib may advantageously be formed of a ring attached to the upper surface of the racket or ski, provided with positioning pins protruding from its lower edge and engaging in corresponding holes in the upper surface of the snowshoe or ski, the ring and the wedge body being made of plastic materials having identical or similar mechanical strengths and with good anti-wear properties.

Selon une réalisation préférée, dans la rainure circulaire du corps de cale, les première et seconde nervures circulaires sont reliées par au moins un bossage coopérant avec des encoches de la nervure de base pour assurer un freinage en rotation du corps de cale dans les orientations fonctionnelles de verrouillage, de déverrouillage et de calage.

Dans le mode de réalisation illustré sur les figures 1 et 2, une cale de montée verrouillante 1 selon l'invention est adaptée sur une raquette à neige 2 munie d'une plaque de fixation 3 articulée autour d'un axe de rotation 4 transversal antérieur. La plaque 3 est munie d'une butée antérieure 5 fixe, et d'une butée postérieure 6 dont la position longitudinale est réglable et blocable sur une crémaillère 7 de la plaque 3. On peut ainsi adapter sur la plaque 3 des chaussures de pointures différentes.In the embodiment illustrated in FIGS. 1 and 2, a locking climbing wedge 1 according to the invention is adapted on a snowshoe 2 provided with a fixing plate 3 articulated around an axis of rotation 4 transverse anterior . The plate 3 is provided with a fixed front stop 5, and a rear stop 6 whose longitudinal position is adjustable and lockable on a rack 7 of the plate 3. It is thus possible to adapt shoes of different sizes on the plate 3 .

Le corps 8 de raquette comporte une plage postérieure 9 rigide, conformée pour recevoir et retenir la cale de montée verrouillante 1 selon l'invention.The racket body 8 comprises a rigid rear range 9, shaped to receive and retain the locking climb wedge 1 according to the invention.

Dans le mode de réalisation représenté sur les figures 3 à 6, la cale 1 est formée d'un corps monobloc 10, monté pivotant autour d'un axe intermédiaire 11 généralement perpendiculaire à la face inférieure 12 de la cale 1 ou face destinée à porter contre la face supérieure 13 de la raquette comme illustré sur la figure 2. Ainsi, l'axe intermédiaire 11 est perpendiculaire à la face supérieure 13 de raquette.In the embodiment shown in FIGS. 3 to 6, the shim 1 is formed of a single-piece body 10, mounted to pivot about an intermediate axis 11 generally perpendicular to the lower face 12 of the shim 1 or face intended to carry against the upper face 13 of the racket as illustrated in Figure 2. Thus, the intermediate axis 11 is perpendicular to the upper face 13 of racket.

Le corps monobloc 10 comprend, dans le mode de réalisation représenté, une première zone périphérique 14 comportant une partie supérieure 15 radialement saillante, c'est-à-dire relativement éloignée de l'axe 11, raccordée par un épaulement inférieur 16 à une partie inférieure 17 radialement en retrait, c'est-à-dire plus rapprochée de l'axe 11.The one-piece body 10 comprises, in the embodiment shown, a first peripheral zone 14 comprising an upper part 15 radially projecting, that is to say relatively distant from the axis 11, connected by a lower shoulder 16 to a part lower 17 radially recessed, that is to say closer to the axis 11.

Le corps 10 comprend une seconde zone périphérique 18 radialement entièrement en retrait, et une troisième zone périphérique 19 radialement proéminente, c'est-à-dire relativement écartée de l'axe intermédiaire 11. Dans le mode de réalisation représenté, la troisième zone périphérique radialement proéminente 19 de cale est diamétralement opposée à la première zone périphérique 14.The body 10 comprises a second peripheral zone 18 radially entirely set back, and a third peripheral zone 19 radially prominent, that is to say relatively spaced from the intermediate axis 11. In the embodiment shown, the third peripheral zone radially prominent 19 of wedge is diametrically opposite to the first peripheral zone 14.

La première zone périphérique 14 comprend une première face supérieure 20, généralement plane et parallèle à la face inférieure 12 ou légèrement inclinée, et écartée de ladite face inférieure 12 d'une distance constituant une cale à une première hauteur H1, par exemple d'environ 15 millimètres.The first peripheral zone 14 comprises a first upper face 20, generally flat and parallel to the lower face 12 or slightly inclined, and spaced from said lower face 12 by a distance constituting a wedge at a first height H1, for example of approximately 15 millimeters.

La troisième zone périphérique radialement proéminente 19 comporte une seconde face supérieure 21 généralement plane et inclinée, constituant une cale à une seconde hauteur H2, par exemple d'environ 35 millimètres.The third radially prominent peripheral zone 19 comprises a second upper face 21 generally flat and inclined, constituting a wedge at a second height H2, for example of about 35 millimeters.

Les faces supérieures 20 et 21 des parties proéminente ou saillante sont avantageusement inclinées sensiblement selon l'inclinaison de la plaque de fixation 3 qui vient en appui sur elles.The upper faces 20 and 21 of the protruding or projecting parts are advantageously inclined substantially according to the inclination of the fixing plate 3 which bears on them.

Le corps monobloc 10 comprend, sur sa face inférieure 12, des nervures et rainures circulaires concentriques centrées sur l'axe intermédiaire 11, telles que les nervures 23 et 24, et la rainure 26, s'engageant dans des rainures et nervures concentriques correspondantes de la face supérieure 13 de raquette. Ainsi, sur les figures 7 et 8, la plage postérieure 9 de la raquette 2 comprend une nervure concentrique 28, devant s'engager dans la rainure 26 de la cale 1. Cet engagement est mieux représenté sur la figure 10.The one-piece body 10 comprises, on its lower face 12, concentric circular ribs and grooves centered on the intermediate axis 11, such as the ribs 23 and 24, and the groove 26, engaging in corresponding concentric grooves and ribs of the upper face 13 of racket. Thus, in FIGS. 7 and 8, the rear pad 9 of the racket 2 comprises a concentric rib 28, which has to engage in the groove 26 of the wedge 1. This engagement is better represented in FIG. 10.

La nervure extérieure 24 du corps monobloc 10 a de préférence un diamètre extérieur d'au moins 40 millimètres, avantageusement de 50 millimètres environ, définissant une base d'appui large du corps 10 pour supporter efficacement les efforts subis par la cale.The outer rib 24 of the one-piece body 10 preferably has an outer diameter of at least 40 millimeters, advantageously about 50 millimeters, defining a wide support base of the body 10 to effectively support the forces undergone by the wedge.

Le corps 10 de la cale 1 se trouve retenu sur la raquette 2 ou le ski par un arbre central de rotation 29 tel que vis, rivet, boulon ou insert.The body 10 of the wedge 1 is retained on the racket 2 or the ski by a central shaft of rotation 29 such as screw, rivet, bolt or insert.

Dans la réalisation illustrée sur les figures, le corps 10 de cale comporte un trou borgne 111, ouvert sur sa face inférieure, et dans lequel se visse en force la tige d'une vis 29 formant l'arbre central de rotation. La tige de vis traverse avec jeu un trou 100 correspondant de la raquette 2.In the embodiment illustrated in the figures, the wedge body 10 has a blind hole 111, open on its underside, and into which the rod of a screw 29 is forcibly screwed forming the central shaft of rotation. The screw rod crosses with clearance a corresponding hole 100 of the racket 2.

La raquette 2 comporte une nervure centrale supérieure 27 concentrique, bordant l'orifice supérieur du trou 100 de raquette, et une nervure centrale inférieure 127 concentrique, bordant l'orifice inférieur du trou 100 de raquette. Le corps 10 de cale comporte un fût inférieur 22, cylindrique à section circulaire, centré sur l'axe intermédiaire 11, et de longueur adaptée pour traverser le trou 100 de raquette et venir en affleurement de la nervure centrale inférieure 127. Le fût 22 est séparé de la nervure intermédiaire 23 par une rainure circulaire 25.The racket 2 has a concentric upper central rib 27 bordering the upper orifice of the racket hole 100, and a concentric lower central rib 127 bordering the lower orifice of the racket hole 100. The wedge body 10 comprises a lower barrel 22, cylindrical with circular section, centered on the intermediate axis 11, and of a length adapted to pass through the racket hole 100 and to come flush with the lower central rib 127. The barrel 22 is separated from the intermediate rib 23 by a circular groove 25.

En position assemblée, dans le mode de réalisation illustré sur la figure 10, la tête de la vis 29 porte contre le bord du fût inférieur 22, et est en appui glissant sur le bord de la nervure centrale inférieure 127, éventuellement avec interposition d'une rondelle. La tête de la vis 29 retient ainsi la vis sous la face inférieure de la raquette 2.In the assembled position, in the embodiment illustrated in FIG. 10, the head of the screw 29 bears against the edge of the lower barrel 22, and is in sliding support on the edge of the lower central rib 127, possibly with interposition of a washer. The head of the screw 29 thus retains the screw under the underside of the racket 2.

L'une au moins des rainures concentriques, par exemple la rainure 26 de la cale 1, comprend au moins un bossage tel que le bossage 30, coopérant avec des encoches telles que l'encoche 31 de la nervure correspondante 28, pour assurer un freinage en rotation de la cale 1 dans ses orientations fonctionnelles de verrouillage, de déverrouillage et de calage. Dans le mode de réalisation représenté, quatre encoches 31 sont disposées en croix et orientées obliquement par rapport à l'axe longitudinal et à l'axe transversal du corps de raquette, par exemple à 45°. Simultanément, dans ce mode de réalisation, les bossages 30 du corps 10 de cale sont au nombre de quatre, et selon les mêmes orientations à 45°. La rotation de la cale 1 à l'écart des orientations fonctionnelles est autorisée par la déformation élastique de la face supérieure 13 de raquette, dans la plage postérieure 9, déformation qui permet la sortie des bossages 30 hors des encoches correspondantes telles que l'encoche 31 lors d'une rotation forcée de la cale 1.At least one of the concentric grooves, for example the groove 26 of the wedge 1, comprises at least one boss such as the boss 30, cooperating with notches such as the notch 31 of the corresponding rib 28, to ensure braking in rotation of the wedge 1 in its functional directions of locking, unlocking and stalling. In the embodiment shown, four notches 31 are arranged in a cross and oriented obliquely with respect to the longitudinal axis and to the transverse axis of the racket body, for example at 45 °. Simultaneously, in this embodiment, the bosses 30 of the wedge body 10 are four in number, and according to the same orientations at 45 °. The rotation of the shim 1 away from the functional orientations is authorized by the elastic deformation of the upper face 13 of the racket, in the posterior range 9, deformation which allows the bosses 30 to exit the corresponding notches such as the notch 31 during forced rotation of the hold 1.

Lors de son adaptation sur la raquette 2, la cale 1 est positionnée sur la face supérieure 13 de raquette 2 avec son axe intermédiaire 11 situé à une distance de l'extrémité postérieure 32 de plaque de fixation 3 qui est supérieure à l'excentration des parties en retrait 17 ou 18 de cale et inférieure à l'excentration des parties saillante 15 ou proéminente 19 de cale. Ainsi positionnée, la cale 1 peut être pivotée autour de son axe 11 entre plusieurs orientations fonctionnelles.When it is adapted to the racket 2, the wedge 1 is positioned on the upper face 13 of the racket 2 with its intermediate axis 11 located at a distance from the rear end 32 of the fixing plate 3 which is greater than the eccentricity of the recessed parts 17 or 18 of the wedge and less than the eccentricity of the protruding parts 15 or protruding 19 of the wedge. Thus positioned, the wedge 1 can be pivoted about its axis 11 between several functional orientations.

Les figures 11 et 12 illustrent une première orientation fonctionnelle de verrouillage, dans laquelle la première zone périphérique 14 de cale est orientée vers la plaque de fixation 3. Dans cette position, l'extrémité postérieure 32 de la plaque de fixation 3 est engagée et retenue sous l'épaulement inférieur 16 de la première zone périphérique 14 de cale, pour son verrouillage, interdisant le soulèvement de la plaque de fixation 3.FIGS. 11 and 12 illustrate a first functional locking orientation, in which the first peripheral wedge zone 14 is oriented towards the fixing plate 3. In this position, the rear end 32 of the fixing plate 3 is engaged and retained under the lower shoulder 16 of the first peripheral zone 14 of the wedge, for its locking, preventing the lifting of the fixing plate 3.

Les figures 13 et 14 illustrent une seconde orientation fonctionnelle de la cale 1, ou orientation de libération ou de déverrouillage. Dans cette position, la cale 1 est pivotée avec sa seconde zone périphérique 18 orientée vers la plaque de fixation 3. Par le fait que la seconde zone périphérique 18 est en retrait, l'extrémité postérieure 32 de la plaque de fixation 3 peut se soulever librement. On autorise ainsi le libre pivotement de la plaque de fixation 3 autour de son axe transversal 4.Figures 13 and 14 illustrate a second functional orientation of the wedge 1, or release or unlocking orientation. In this position, the wedge 1 is pivoted with its second peripheral zone 18 oriented towards the fixing plate 3. By the fact that the second peripheral zone 18 is set back, the rear end 32 of the fixing plate 3 can be raised freely. This allows the free pivoting of the fixing plate 3 around its transverse axis 4.

Les figures 15 et 16 illustrent une autre orientation fonctionnelle de la cale 1, ou première orientation fonctionnelle de calage. Dans cette position, la cale 1 est pivotée avec sa première zone périphérique 14 orientée vers la plaque de fixation 3, mais la plaque de fixation 3 étant préalablement soulevée. Dans cette position, l'extrémité postérieure 32 de la plaque de fixation 3 est au-dessus de la cale 1, et peut pivoter autour de son axe transversal 4 jusqu'à venir en appui sur la face supérieure 20 de la première zone périphérique 14.Figures 15 and 16 illustrate another functional orientation of the wedge 1, or first functional orientation of wedging. In this position, the wedge 1 is pivoted with its first peripheral zone 14 oriented towards the fixing plate 3, but the fixing plate 3 being lifted beforehand. In this position, the rear end 32 of the fixing plate 3 is above the wedge 1, and can pivot around its transverse axis 4 until it comes to bear on the upper face 20 of the first peripheral zone 14 .

Les figures 17 et 18 illustrent une autre orientation fonctionnelle de la cale 1, ou seconde orientation fonctionnelle de calage. Dans cette position, la cale 1 est pivotée avec sa zone périphérique radialement proéminente 19 orientée vers la plaque de fixation 3, la plaque de fixation 3 étant préalablement relevée au-dessus de la cale 1. Dans cette position, l'extrémité postérieure 32 de la plaque de fixation 3 peut se soulever librement et autoriser le pivotement de la plaque 3 autour de son axe transversal 4, jusqu'à venir en appui sur la face supérieure 21 de la zone périphérique radialement proéminente 19.Figures 17 and 18 illustrate another functional orientation of the shim 1, or second functional setting orientation. In this position, the wedge 1 is pivoted with its radially prominent peripheral zone 19 oriented towards the fixing plate 3, the fixing plate 3 being previously raised above the wedge 1. In this position, the rear end 32 of the plaque of attachment 3 can be lifted freely and allow the plate 3 to pivot about its transverse axis 4, until it comes to bear on the upper face 21 of the radially prominent peripheral zone 19.

On comprendra que la structure particulière de cale 1 selon l'invention assure à la fois une grande facilité de manoeuvre de la cale 1 par simple rotation, la cale étant toujours accessible pour une manoeuvre à la main. Egalement, la forme particulière du corps 10 de cale assure un maintien efficace de la cale 1 sur la raquette ou le ski, et permet une bonne reprise des efforts mécaniques subis par la cale lors de l'utilisation.It will be understood that the particular structure of wedge 1 according to the invention ensures both great ease of maneuvering of the wedge 1 by simple rotation, the wedge being always accessible for maneuvering by hand. Also, the particular shape of the wedge body 10 ensures effective maintenance of the wedge 1 on the racket or the ski, and allows good recovery of the mechanical forces undergone by the wedge during use.

Dans le mode de réalisation illustré sur les figures 19 à 22, la nervure de base 28 circulaire, comportant les encoches 31, est formée d'une bague 128 rapportée sur la surface supérieure 13 de raquette ou de ski, munie d'ergots de positionnement 129 dépassant de son bord inférieur et s'engageant dans des trous correspondants 229 de la face supérieure 13 de raquette ou de ski. La bague 128 et le corps 10 sont réalisés en des matières plastiques mécaniquement résistantes et présentant de bonnes propriétés anti-usure. On évite ainsi que les bossages 30 provoquent une usure prématurée ou une déformation prématurée de la nervure de base circulaire 28, lorsque le corps 2 de raquette ou de ski est formé d'un matériau plastique malléable ou présentant une moindre résistance à l'usure et à l'abrasion. Dans ce mode de réalisation, la nervure de base 28 porte par sa crête dans le fond de la rainure 26.In the embodiment illustrated in FIGS. 19 to 22, the circular base rib 28, comprising the notches 31, is formed of a ring 128 attached to the upper surface 13 of snowshoe or ski, provided with positioning lugs 129 protruding from its lower edge and engaging in corresponding holes 229 of the upper face 13 of snowshoeing or skiing. The ring 128 and the body 10 are made of mechanically resistant plastics and having good anti-wear properties. This prevents the bosses 30 causing premature wear or premature deformation of the circular base rib 28, when the body 2 of snowshoe or ski is formed of a malleable plastic material or having less resistance to wear and abrasion. In this embodiment, the base rib 28 carries by its crest in the bottom of the groove 26.

Dans le mode de réalisation illustré sur la figure 22, l'assemblage du corps 10 de cale sur le corps 2 de raquette s'effectue par la vis 29, dont la tige est vissée en force dans le trou borgne 111 du corps 10 de cale. Une rondelle 130, en matériau élastiquement compressible, est insérée entre la tête de la vis 29 et un épaulement intérieur 131 du trou 100 de raquette. La nervure centrale inférieure 127 de raquette contient radialement la rondelle élastique 130. Deux rondelles rigides 133 et 134 contiennent axialement la rondelle élastique 130. La compression contrôlée de la rondelle élastique 130 autorise un léger déplacement vertical du corps 10 de cale, lors des manoeuvres de rotation, pour autoriser la sortie des bossages 30 hors des encoches 31.In the embodiment illustrated in FIG. 22, the assembly of the wedge body 10 on the racket body 2 is carried out by the screw 29, the rod of which is forcibly screwed into the blind hole 111 of the wedge body 10 . A washer 130, made of elastically compressible material, is inserted between the head of the screw 29 and an internal shoulder 131 of the racket hole 100. The lower central rib 127 of the racket contains the elastic washer 130 radially. Two rigid washers 133 and 134 axially contain the elastic washer 130. The controlled compression of the elastic washer 130 allows a slight vertical movement of the wedge body 10, during the maneuvers of rotation, to allow the bosses 30 to exit from the notches 31.

Comme on le voit sur les modes de réalisation illustrés sur les figures, le corps 10 de cale comprend des faces supérieures 20 et 21 planes et larges de parties saillante 15 ou proéminente 19, inclinées sensiblement selon l'inclinaison de la surface de fixation 3 ou de chaussure qui vient en appui sur elles, et pouvant avantageusement être partiellement revêtues d'une couche 132 de matériau élastique, par exemple sous forme d'un bouton encliqueté dans un trou approprié.As can be seen in the embodiments illustrated in the figures, the wedge body 10 includes upper faces 20 and 21 that are planar and wide with projecting portions 15 or prominent 19, inclined substantially according to the inclination of the fastening surface 3 or shoe which comes to bear on them, and which can advantageously be partially coated with a layer 132 of elastic material, for example in the form of a button snapped into a suitable hole.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations qui sont à la portée de l'homme du métier.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations which are within the reach of those skilled in the art.
