Description

La présente invention concerne une raquette à neige et plus particulièrement le dispositif de retenue de la chaussure sur celle-ci. Elle concerne également une chaussure associée destinée à s'assembler à la raquette à neige de l'invention.The present invention relates to a snowshoe and more particularly the shoe retaining device thereon. She also relates to an associated shoe intended to be assembled with the snowshoe of the invention.

Les raquettes à neige sont des engins connus depuis de très nombreuses années car utilisées depuis plusieurs siècles par les populations scandinaves pour se déplacer sur la neige. Jusqu'à nos jours, les raquettes à neige étaient utilisées à des fins utilitaires ou militaires, pour permettre aux populations et aux troupes alpines de se déplacer sur la neige pour leurs déplacements nécessités par la vie quotidienne. Actuellement, les raquettes à neige sont plutôt utilisées par des promeneurs ou des sportifs qui font des randonnées et des promenades, voire même des compétitions.Snowshoes have been known for a long time many years because used for several centuries by Scandinavian people to move on the snow. Until our days, snowshoes were used for utility or military purposes, to allow the populations and the alpine troops to move on the snow for their daily necessities. Currently, snowshoes are used more by walkers or sportsmen who go on hikes and walks, even competitions.

Il existe déjà différents types de dispositifs pour retenir la chaussure sur la raquette. On en connaít plus particulièrement deux types : celui dit à plaque et celui dit à chausson caoutchouc. Généralement, les dispositifs du type à plaque sont le plus souvent utilisés par les sportifs soucieux de performances car la retenue du pied est assurée avec plus de rigidité, tandis que les dispositifs du type à chausson caoutchouc sont plutôt préférés des promeneurs pas trop exigeants et moins soucieux des performances.There are already different types of devices to retain the shoe on the racket. We know more particularly two types: the one saying on the plate and the one saying on the rubber liner. Generally, plate type devices are most often used by athletes concerned about performance because the restraint of the foot is ensured with more stiffness, while rubber liner type devices are rather preferred by walkers who are not too demanding and less concerned with performance.

On connaít par exemple la raquette divulguée dans la demande de brevet FR-A-2-744-623 et qui comprend une plaque articulée sur laquelle est fixée la chaussure avec de lanieur.We know for example the racket disclosed in the application FR-A-2-744-623 and which includes a plate articulated on which is fixed the shoe with lanieur.

Toutefois, quel que soit le type de fixation utilisé, celui-ci présente de nombreux inconvénients liés soit à un problème de tenue du pied, comme dans le cas des chaussons caoutchouc, soit à des problèmes de confort d'utilisation (systèmes à plaque). En effet, les dispositifs à plaque présentent généralement des moyens de retenue dont la mise en place autour de la chaussure est longue et fastidieuse. However, regardless of the type of attachment used, it has many drawbacks linked to either a problem with the foot, as in the case of rubber slippers, either to comfort of use (plate systems). Indeed, plate devices generally have retaining means, the placement of which around the shoe is long and tedious.

Selon sa caractéristique principale, la raquette à neige de l'invention est du type constituée par un tamis, et comprenant des moyens de retenue destinés à retenir la chaussure de l'utilisateur et est telle que les moyens de retenue sont disposés de part et d'autre de la chaussure au niveau de la partie avant de celle-ci, et constitués par deux profils en saillie ou en creux pouvant coopérer avec des moyens d'accrochage complémentaires de la chaussure, permettant ainsi à la chaussure de pivoter par rapport à la raquette autour d'un axe transversal.According to its main characteristic, the snowshoe of the invention is of the type constituted by a sieve, and comprising means restraint intended to retain the user's shoe and is such that the retaining means are arranged on either side of the boot at the front part thereof, and constituted by two protruding or recessed profiles able to cooperate with complementary attachment means of the shoe, thus allowing the shoe to rotate with respect to the racket around a transverse axis.

Elle comporte des moyens de retenue (MR) destinés à permettre la solidarisation de la chaussure (4) à la raquette à neige, comme le montrent les figures 1 à 4, lesdits moyens de retenue pouvant être montés sur le cadre principal (3) ou sur des parois internes (5) rigides qui forment le tamis (2), ou tout autre élément.The snowshoe of the invention, bearing the general reference (1), is of the type comprising a screen (2) delimited by a main frame (3), said sieve can be in the form of an openwork plate formed of a set of rigid internal walls (5) intended to ensure its lift or in the form of a canvas as in the case of snowshoes tubular type of North American origin. It includes means of retainer (MR) intended to allow the shoe (4) to be secured to the snowshoe, as shown in Figures 1 to 4, said means of retainer that can be mounted on the main frame (3) or on walls internal (5) rigid which form the screen (2), or any other element.

    Selon l'invention, les moyens de retenue (MR) sont constitués par au moins deux profils en saillie (6a, 6b) qui viennent s'introduire dans des profils en creux (7a, 7b) de forme complémentaire, disposés dans la chaussure (4) pour retenir celle-ci à la raquette (1). Au moins un de ces profils en saillie (6a, 6b) est disposé mobile entre une position de retenue (A) où il coopère avec un des profils en creux (7a, 7b) correspondants de la chaussure et une position dite de déverrouillage (B) dans laquelle il s'est retiré dudit profil en creux, permettant ainsi à l'utilisateur de désolidariser sa chaussure (4) de la raquette (1). On peut noter que, selon les modes de réalisation illustrés de la raquette à neige de l'invention, les deux profils en saillie (6a, 6b) sont avantageusement montés mobiles entre les deux positions de retenue et de déverrouillage précitées (A, B), comme le montrent les figures 5 et 6. Toutefois, selon des variantes d'exécution possibles, seul un profil en saillie pourrait être mobile par rapport à la chaussure, tandis que l'autre serait fixe, le profil mobile permettant à lui seul le verrouillage et le déverrouillage de la chaussure. Notons que les profils en creux (7a, 7b) de la chaussure sont disposés dans la semelle, par exemple, et forment les moyens d'accrochage complémentaires qui sont destinés à coopérer avec les moyens de retenue (MR) de la raquette.According to the invention, the retaining means (MR) consist of at least two protruding profiles (6a, 6b) which are introduced into hollow profiles (7a, 7b) of complementary shape, arranged in the shoe (4) for retaining it to the racket (1). At least one of these protruding profiles (6a, 6b) is arranged movable between a retaining position (A) where it cooperates with one of the hollow profiles (7a, 7b) corresponding to the shoe and a so-called unlocking position (B) in which it is removed from said hollow profile, thus allowing the user to separate his shoe (4) of the racket (1). It can be noted that, depending on the modes of illustrated embodiment of the snowshoe of the invention, the two profiles in projection (6a, 6b) are advantageously mounted movable between the two the aforementioned retaining and unlocking positions (A, B), such as the show Figures 5 and 6. However, according to alternative embodiments possible, only a protruding profile could be movable relative to the shoe, while the other would be fixed, the movable profile allowing him only locking and unlocking the shoe. Note that the hollow profiles (7a, 7b) of the shoe are arranged in the sole, for example, and form the additional attachment means which are intended to cooperate with the retaining means (MR) of the racket.

    Selon l'invention, les moyens de retenue (MR) de la chaussure (4) sur la raquette à neige (1) permettent à la chaussure de pivoter par rapport à la raquette autour d'un axe transversal (YY') orthogonal au plan longitudinal (P) de symétrie générale de la raquette, comme le montrent les figures 2 et 3, ce pivotement pouvant être limité dans son amplitude par un système de butée de manière connue en soi.According to the invention, the retaining means (MR) of the shoe (4) on the snowshoe (1) allow the boot to pivot relative to the racket around a transverse axis (YY ') orthogonal to the plane longitudinal (P) of general symmetry of the racket, as shown Figures 2 and 3, this pivoting can be limited in its amplitude by a stop system in a manner known per se.

    Pour ce faire, le pivotement de la chaussure peut s'effectuer soit grâce à la rotation relative des profils en saillie (6a, 6b) à l'intérieur des profils en creux (7a, 7b) de la chaussure (4) comme dans le mode de réalisation préféré illustré où ceux-ci sont constitués par des portions d'axe susceptibles de pivoter à l'intérieur de logements d'axe complémentaires de la chaussure, soit grâce au pivotement des profils en saillie (6a, 6b) des moyens de retenue (MR) par rapport à la raquette (1) qui les porte. Dans cette deuxième hypothèse, la coopération des profils en saillie et des profils en creux est bloquée en rotation autour de l'axe transversal (YY') grâce à la forme spécifique complémentaire de leur profil longitudinal, par exemple, et l'articulation s'effectue entre le support ou embase des profils en saillie qui est disposé fixe sur la raquette à neige (1) et le profil en saillie lui-même, tandis que la chaussure est solidaire en rotation dudit profil. Selon ces dernières variantes non représentées, les profils en saillie peuvent alors être de forme parallélépipédique ou présenter un profil triangulaire, par exemple, le mécanisme de pivotement étant situé à l'intérieur des supports ou embase.To do this, the shoe can be pivoted either thanks to the relative rotation of the protruding profiles (6a, 6b) inside the hollow profiles (7a, 7b) of the shoe (4) as in the mode of illustrated preferred embodiment where these consist of portions of axis likely to pivot inside complementary axis housings of the shoe, either by pivoting the projecting profiles (6a, 6b) of the retaining means (MR) relative to the racket (1) which carries them. In this second hypothesis, the cooperation of the protruding profiles and hollow profiles is blocked in rotation about the transverse axis (YY ') thanks to the specific shape complementary to their longitudinal profile, by example, and the articulation takes place between the support or base of the profiles projecting which is arranged fixed on the snowshoe (1) and the projecting profile itself, while the shoe is integral in rotation with said profile. According to these latter variants, not shown, the protruding profiles can then be of rectangular shape or have a profile triangular, for example, the pivot mechanism being located inside the supports or base.

    Selon le mode de réalisation préféré de la raquette à neige (1), les profils en saillie sont avantageusement formés par des portions d'axe (6a, 6b) qui coopèrent avec des logements d'axes (7a, 7b) situés dans la semelle (4a) de la chaussure (4). Selon l'invention, les portions d'axe (6a, 6b) sont positionnées coaxialement selon un axe transversal (YY') orthogonal au plan longitudinal (P) de la raquette à neige (1). Elles sont montées sur le tamis de la raquette à neige (1) par le biais de supports d'axe latéraux (8a, 8b) et d'organes de déverrouillage (9a, 9b) qui gèrent leurs mouvements respectifs par rapport à la chaussure et la raquette pour permettre la mise en place des moyens de retenue (MR) de la raquette à neige dans ceux de la chaussure.According to the preferred embodiment of the snowshoe (1), the protruding profiles are advantageously formed by axis portions (6a, 6b) which cooperate with axis housings (7a, 7b) located in the sole (4a) of the shoe (4). According to the invention, the axis portions (6a, 6b) are positioned coaxially along a transverse axis (YY ') orthogonal to the longitudinal plane (P) of the snowshoe (1). They are mounted on the sieve of the snowshoe (1) by means of supports lateral axes (8a, 8b) and unlocking members (9a, 9b) which manage their respective movements with respect to the shoe and the racket for allow the installation of retaining means (MR) of the racket to snow in those of the shoe.

    Selon le mode de réalisation préféré de la raquette à neige (1) de l'invention, les deux portions d'axe (6a, 6b) sont mobiles en translation selon leur axe de révolution (YY') pour pouvoir s'introduire dans les logements d'axe (7a, 7b) d'un insert (51) situé dans la partie avant de la semelle de la chaussure (4). Selon ce mode de réalisation, ces portions d'axe (6a, 6b) sont chacune montées fixes sur un organe de déverrouillage respectif (9a, 9b) susceptible de coulisser transversalement sur un support d'axe (8a, 8b) fixé au tamis (2) de la raquette. Notons que, selon l'invention, le coulissement entre l'organe de déverrouillage (9a, 9b) et le support d'axe (8a, 8b) s'effectue à l'encontre de moyens de sollicitation élastiques (MSE) qui sollicitent en permanence l'organe de déverrouillage (9a, 9b) et sa portion d'axe (6a, 6b) vers sa position de retenue (A). Ces moyens de sollicitation (MSE) peuvent être de tous types comme, par exemple, être formés par un ressort de compression (10) disposé entre une surface de butée (11) solidaire de la portion d'axe (6a, 6b) et une autre surface d'appui (12) située sur le support d'axe (8a, 8b).According to the preferred embodiment of the snowshoe (1) of the invention, the two axis portions (6a, 6b) are movable in translation along their axis of revolution (YY ') to be able to enter the axis housings (7a, 7b) of an insert (51) located in the front part of the shoe sole (4). According to this embodiment, these portions axis (6a, 6b) are each fixed mounted on an unlocking member respective (9a, 9b) capable of sliding transversely on a support axis (8a, 8b) fixed to the screen (2) of the racket. Note that, according to the invention, the sliding between the unlocking member (9a, 9b) and the axis support (8a, 8b) is carried out against biasing means elastic bands (MSE) which permanently stress the unlocking member (9a, 9b) and its axis portion (6a, 6b) towards its retaining position (A). These Solicitation means (MSE) can be of all types, such as example, be formed by a compression spring (10) disposed between a abutment surface (11) integral with the axle portion (6a, 6b) and another bearing surface (12) located on the axle support (8a, 8b).

    Selon le mode de réalisation préféré de la raquette à neige (1) et comme le montrent les figures 4 à 7, les supports (8a, 8b) se présentent sous la forme d'une partie supérieure appelée canon, constituée d'une portion de tube cylindrique (13) portant à une des extrémités de son alésage la surface d'appui transversale (12), surface d'appui qui possède un orifice au travers duquel la portion d'axe (6a) est susceptible de coulisser. Selon le mode de réalisation préféré, la portion d'axe (6a, 6b) porte une collerette annulaire (11) qui forme butée pour le ressort (10) et qui est destinée à coulisser dans l'alésage (13a) du canon (13) sur la longueur de celui-ci, ladite collerette présentant un diamètre identique à celui de l'alésage. Cette partie supérieure ou canon (13) est prolongée vers le bas par un rail inférieur de fixation (14) destiné à coopérer avec un rail de forme complémentaire (15) situé avantageusement sur le tamis (2). Notons que cette coopération s'effectue par coulissement jusqu'à ce qu'une surface de butée interne non représentée du support (8a, 8b) vienne en butée sur une surface de butée du rail complémentaire (15) du tamis.According to the preferred embodiment of the snowshoe (1) and as shown in Figures 4 to 7, the supports (8a, 8b) are presented in the form of an upper part called a cannon, consisting of a portion of cylindrical tube (13) bearing at one end of its bore the transverse bearing surface (12), a bearing surface which has an orifice through which the axis portion (6a) is capable of slide. According to the preferred embodiment, the axis portion (6a, 6b) carries an annular flange (11) which forms a stop for the spring (10) and which is intended to slide in the bore (13a) of the barrel (13) on the length thereof, said collar having a diameter identical to that of the bore. This upper part or barrel (13) is extended towards the bottom by a lower fixing rail (14) intended to cooperate with a rail of complementary shape (15) advantageously located on the screen (2). Note that this cooperation takes place by sliding until a internal abutment surface not shown of the support (8a, 8b) comes in abutment on an abutment surface of the complementary rail (15) of the screen.

    La portion d'axe (6a, 6b) présente, du côté interne, un téton de coopération (17) dont le diamètre est identique au jeu près à celui des logements d'axe (7a, 7b), tandis que, de l'autre côté de la collerette (11), il présente une tige (19) destinée à passer dans le ressort (10) situé à l'intérieur de l'alésage (13a) du canon (13) pour traverser ensuite la surface d'appui (12) du canon avant d'être fixée grâce à un système de filetage interne et de vis (18) à l'organe de déverrouillage (9a, 9b).The axis portion (6a, 6b) has, on the internal side, a nipple of cooperation (17) whose diameter is identical to the clearance close to that of the axis housings (7a, 7b), while, on the other side of the flange (11), there has a rod (19) intended to pass through the spring (10) located at inside the bore (13a) of the barrel (13) to then pass through the surface support (12) of the barrel before being fixed by means of a threading system internal and screw (18) to the unlocking member (9a, 9b).

    Il est important de noter que le support d'axe (8a, 8b) présente sur sa partie supérieure deux gorges de guidage (21a, 21b) qui permettent à l'organe de déverrouillage (9a, 9b) de venir coulisser sur son support, entraínant dans son coulissement le mouvement de la portion d'axe (6a, 6b) et plus particulièrement de son téton (17) qui, en position de déverrouillage (B), vient s'escamoter à l'intérieur de l'alésage (13a) du canon (13). Pour ce faire, l'organe de déverrouillage (9a, 9b) se présente sous la forme d'un capot coulissant qui comporte une forme interne complémentaire de la forme externe du support d'axe (8a,8b) pour pouvoir l'épouser lorsqu'ils se trouvent en position de retenue (A), comme le montrent les figures 7 et 8a. L'organe de déverrouillage (9a, 9b) présente ainsi sur sa face interne deux saillies de guidage (20a, 20b) internes destinées à coopérer avec les gorges (21a, 21b) du canon (13) pour assurer le coulissement.It is important to note that the axle support (8a, 8b) on its upper part two guide grooves (21a, 21b) which allow the unlocking member (9a, 9b) sliding on its support, causing the movement of the axis portion in its sliding (6a, 6b) and more particularly of its stud (17) which, in the position of unlocking (B), is retracted inside the bore (13a) of the barrel (13). To do this, the unlocking member (9a, 9b) is presented in the form of a sliding cover which has an internal shape complementary to the external shape of the axle support (8a, 8b) to be able marry him when they are in the retaining position (A), as the show Figures 7 and 8a. The unlocking member (9a, 9b) has thus on its internal face two internal guide projections (20a, 20b) intended to cooperate with the grooves (21a, 21b) of the barrel (13) to ensure sliding.

    Selon le mode de réalisation préféré de la raquette à neige (1) de l'invention et comme le montrent les figures 8a et 8b, l'organe de déverrouillage (9a, 9b) présente sur sa face externe une surface d'appui principale (23) située, par exemple, dans un profil en creux (22) et qui est destinée à être sollicitée pour provoquer le déverrouillage des moyens de retenue (MR) grâce au coulissement de l'organe (9a, 9b) qui s'ensuit. Cette surface d'appui principal (23) est avantageusement une surface orthogonale à l'axe transversal (YY') ou légèrement inclinée par rapport au plan orthogonal à l'axe afin de pouvoir être sollicitée en translation selon l'axe transversal (YY') par une poussée exercée par un accessoire tel qu'un bâton de ski (27), voir figure 8a. L'organe de déverrouillage présente également une couronne externe (41) destinée à faciliter son actionnement par l'utilisateur de manière manuelle, tel que cela est illustré à la figure 8a.According to the preferred embodiment of the snowshoe (1) of the invention and as shown in Figures 8a and 8b, the unlocking (9a, 9b) has a bearing surface on its external face main (23) located, for example, in a hollow profile (22) and which is intended to be used to cause the unlocking of the means of retained (MR) by sliding of the member (9a, 9b) which follows. This main bearing surface (23) is advantageously a surface orthogonal to the transverse axis (YY ') or slightly inclined relative to the plane orthogonal to the axis in order to be able to be requested in translation according to the transverse axis (YY ') by a thrust exerted by an accessory such as ski pole (27), see Figure 8a. The unlocking member presents also an external crown (41) intended to facilitate its actuation by the user manually, as illustrated in Figure 8a.

    On peut noter que, selon le mode de réalisation préféré des moyens de retenue (MR) de la raquette à neige, la fixation des moyens de retenue sur le tamis (2) de la raquette à neige s'effectue uniquement à l'aide d'un dispositif de rail et de glissière (14, 15, 20a, 20b, 21a, 21b), le support (8a, 8b) venant se fixer par coulissement sur le rail (15) du tamis (2) avant que l'organe de déverrouillage (9a, 9b) vienne se fixer sur le support (8a, 8b) également par coulissement autour des gorges de guidage (21a, 21b), la fixation de la portion d'axe (6a, 6b) sur l'organe de déverrouillage (9a, 9b) par la vis (18) permettant de verrouiller le dispositif en empêchant les parties constitutives (6a, 6b, 8a, 8b, 9a, 9b) des moyens de retenue (MR) de se séparer. Par ailleurs, il est important de noter que le capot de déverrouillage (9a, 9b), l'organe support (8a, 8b) et leur portion d'axe (6a, 6b), une fois assemblés et mis en place sur le tamis (2), forment ensemble une enceinte fermée, de manière à empêcher la neige de s'introduire dans le mécanisme.It may be noted that, according to the preferred embodiment of the retaining means (MR) of the snowshoe, fixing the means of retained on the sieve (2) of the snowshoe is made only at using a rail and slide device (14, 15, 20a, 20b, 21a, 21b), the support (8a, 8b) which is fixed by sliding on the rail (15) of the screen (2) before the unlocking member (9a, 9b) is fixed on the support (8a, 8b) also by sliding around the guide grooves (21a, 21b), the fixing of the axle portion (6a, 6b) on the unlocking (9a, 9b) by the screw (18) allowing the device to be locked by preventing the constituent parts (6a, 6b, 8a, 8b, 9a, 9b) from the means of restraint (MR) to separate. Furthermore, it is important to note that the unlocking cover (9a, 9b), the support member (8a, 8b) and their portion axis (6a, 6b), once assembled and placed on the screen (2), form together a closed enclosure, so as to prevent snow from enter the mechanism.

    Par ailleurs, on peut noter que la tige (19) de la portion d'axe (6a, 6b) est montée fixe sur l'organe de déverrouillage (9a, 9b), une surface d'appui non représentée située à l'extrémité de la tige venant dans un logement de forme complémentaire de l'organe pour bloquer la portion d'axe en rotation.Furthermore, it can be noted that the rod (19) of the axle portion (6a, 6b) is fixedly mounted on the unlocking member (9a, 9b), a surface support not shown located at the end of the rod coming in a housing of complementary shape of the member to block the portion axis in rotation.

    Selon le mode de réalisation préféré de la raquette à neige (1), le tamis comporte dans sa partie centrale, à l'aplomb de la chaussure de l'utilisateur, un ensemble de parois ou de traverses d'appui (25) qui permet à la chaussure de reposer sur le tamis de la raquette à neige, comme le montre la figure 2. Ces parois et traverses s'étendent sous la partie arrière de la chaussure, le tamis (2) présentant une ouverture (26) située devant l'axe transversal (YY') pour permettre le pivotement de la chaussure (4) vers l'avant. On peut noter que la limitation du pivotement respectif entre le tamis (2) et la chaussure (4) peut être gérée par des surfaces de butée disposées sur le tamis en dessous de l'ouverture avant (26). Toutefois, il peut également être géré directement à l'aide des organes qui assurent ledit pivotement, c'est-à-dire les portions d'axe et les logements complémentaires situés dans la semelle sans pour autant sortir du champ de protection de l'invention.According to the preferred embodiment of the snowshoe (1), the sieve has in its central part, plumb with the shoe of the user, a set of supporting walls or crosspieces (25) which allows the shoe to rest on the sieve of the snowshoe, as shown in figure 2. These walls and crosspieces extend under the rear part of the shoe, the screen (2) having an opening (26) located in front of the transverse axis (YY ') to allow the pivoting of the shoe (4) forwards. It can be noted that the limitation of pivoting between the sieve (2) and the shoe (4) can be managed by abutment surfaces arranged on the screen below the opening before (26). However, it can also be managed directly using the organs which ensure said pivoting, that is to say the axis portions and the complementary housings located in the sole without going out of the protective field of the invention.

    On peut noter que les moyens de retenue (MR) de la raquette à neige sont disposés de part et d'autre de la chaussure coaxialement au niveau de la partie avant de celle-ci pour que l'articulation s'effectue autour d'un axe (YY') situé sensiblement au niveau de l'extrémité avant de la voûte plantaire de l'utilisateur tel qu'illustré figure 9.It can be noted that the retaining means (MR) of the racket at snow are arranged on either side of the shoe coaxially at level of the front part of it so that the articulation takes place around an axis (YY ') located substantially at the front end of the user's arch as illustrated in Figure 9.

    Par ailleurs, l'invention concerne également une chaussure associée, destinée à venir coopérer avec les moyens de retenue (MR) de la raquette à neige (1) de l'invention. Cette chaussure comporte avantageusement deux logements en creux destinés à coopérer avec les profils en saillie (6a, 6b) des moyens de retenue (MR). Ces logements sont avantageusement des logements d'axe (7a, 7b) et sont portés par un insert (51) disposé dans la semelle (4a) de la chaussure (4). Cet insert peut présenter sensiblement une forme d'hyperbole couchée, comme le montre la figure 9, mais il peut également être droit. Selon le mode de réalisation préféré de la chaussure destinée à coopérer avec la raquette à neige, la semelle (4a) ou les extrémités de l'insert (51) qu'elle comporte présente au niveau de l'embouchure des logements d'axe (7a, 7b) une rampe d'introduction (30) destinée repousser le téton de coopération (17) de la portion d'axe (6a, 6b), et à le guider dans son logement (7a, 7b). On peut noter que l'extrémité des tétons de coopération (17) peut aussi être biseautée pour favoriser sa coopération avec la rampe (30) lors de la mise en place de la chaussure (4).Furthermore, the invention also relates to a shoe partner, intended to cooperate with the retaining means (MR) of the snowshoe (1) of the invention. This shoe features advantageously two recessed housings intended to cooperate with the protruding profiles (6a, 6b) of the retaining means (MR). These accommodations are advantageously axis housings (7a, 7b) and are carried by an insert (51) disposed in the sole (4a) of the shoe (4). This insert can show substantially a form of supine hyperbola, as shown Figure 9, but it can also be straight. According to the embodiment preferred shoe intended to cooperate with the snowshoe, the sole (4a) or the ends of the insert (51) which it comprises present at the level of the mouth of the axis housings (7a, 7b) a ramp introduction (30) intended to push the cooperation stud (17) from the axis portion (6a, 6b), and to guide it into its housing (7a, 7b). We can note that the end of the cooperation pins (17) can also be bevelled to promote its cooperation with the ramp (30) when setting in place of the shoe (4).

    A la lecture de la description, on a compris que la chaussure (4) est retenue sur la raquette par les saillies (6a, 6b) qui, sous l'action du ou des ressort(s), sont sollicitées l'une vers l'autre, et retiennent ainsi la chaussure par pincement de son insert. On a compris aussi que la mise en place de la chaussure sur la raquette se fait automatiquement, par simple déplacement de ladite chaussure vers le bas selon F (voir figure 5a). Lors de ce mouvement, l'insert (51), grâce à ses rampes inférieures (52), repousse l'une ou l'autre des saillies de retenue (6a, 6b), contre l'action du ou des ressort(s), et ce jusqu'à enclenchement desdites saillies dans les creux correspondants de l'insert. Quant au déchaussage, il se fait par simple déplacement latéral vers l'extérieur, de l'un ou l'autre des organes de déverrouillage (9a, 9b), le déplacement latéral pouvant se faire manuellement (voir figure 8a)par action de l'utilisateur sur la couronne externe (41), ou par action par la pointe du bâton (voir figure 8b) par coopération de cette dernière dans le profil en creux (22) destiné à cet effet. Lors de cette opération, l'organe de déverrouillage entraíne dans son déplacement latéral la saillie correspondante, ce qui libère la chaussure.Reading the description, it will be understood that the shoe (4) is retained on the racket by the projections (6a, 6b) which, under the action of the spring (s), are biased towards each other, and thus retain the shoe by pinching its insert. We also understood that the establishment of the shoe on the racket is done automatically, by simple displacement of said shoe down along F (see FIG. 5a). then from this movement, the insert (51), thanks to its lower ramps (52), pushes either of the retaining projections (6a, 6b) against the action of the or springs, and this until said projections are engaged in the corresponding hollow of the insert. As for heaving, it is done by simple lateral displacement towards the outside, of one or other of the organs unlocking (9a, 9b), the lateral movement being possible manually (see figure 8a) by user action on the crown external (41), or by action by the tip of the stick (see Figure 8b) by cooperation of the latter in the hollow profile (22) intended for this effect. During this operation, the unlocking member involves in its lateral displacement of the corresponding projection, which releases the shoe.

    La figure 10, illustre une variante d'exécution du téton de coopération, selon laquelle, l'extrémité en forme de cône comprend par exemple deux fentes, afin de favoriser le débourrage de la neige qui pourrait être logée dans le creux de coopération, correspondant de la chaussure. Dans ce cas les portions d'axes (9a,9b) pourraient être bloquées en rotation dans leur logement respectif. Bien entendu l'extrémité de la saillie pourrait aussi avoir la forme d'une pointe de diamant.FIG. 10 illustrates an alternative embodiment of the nipple of cooperation, whereby the cone-shaped end comprises by example two slots, in order to favor the cleaning of the snow which could be housed in the cooperation trough, corresponding to the shoe. In this case the axis portions (9a, 9b) could be blocked rotating in their respective housing. Of course the end of the protrusion could also have the shape of a diamond point.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
