Description

La présente invention concerne un perfectionnement pour raquette à neige destiné à améliorer le confort et l'accroche de la raquette à neige pour le pratiquant, et ce, plus particulièrement pour les raquettes à neige du type comportant un cadre tubulaire et un tamis au moins en partie réalisé en toile, l'invention concerne également un procédé de fabrication de ce type de raquette à neige, ledit procédé étant destiné à permettre la fabrication d'une gamme de raquette de taille différente.The present invention relates to an improvement for snowshoe designed to improve the comfort and grip of the snowshoeing for the practitioner, and more particularly for snowshoes of the type comprising a tubular frame and a sieve less partly made of canvas, the invention also relates to a method of manufacturing this type of snowshoe, said method being intended to allow the manufacture of a range of size rackets different.

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. Mais les sportifs, bien que pratiquant pour leur plaisir, sont de plus en plus exigeants pour le matériel qu'ils utilisent, et il est vrai que les produits actuellement vendus ne donnent pas entière satisfaction.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. But sportsmen, although practicing for their pleasure, are more and more demanding for the material they use, and it is true that the products currently sold do not give whole satisfaction.

On connaít de nombreuses raquettes à neige du type comportant un cadre tubulaire portant un tamis en toile, ces raquettes étant généralement les raquettes à neige à utilisées en Amérique du nord. Toutefois, ces raquettes présentent de nombreux inconvénients liés à leur accroche dans certains types de terrains et surtout dans certaines conditions de neige. En effet, si ces raquettes sont bien adaptées dans les terrains nécessitant une grande portance tel que dans la neige fraíche, elle manquent sensiblement d'accroche dans les surfaces en dévers ou dans des terrains où la neige est plus dure par exemple. Les problèmes d'accroche ont poussé certains fabricants à installer sous la toile des crampons ou autres couteaux. Toutefois les résultats obtenus sont loin d'être satisfaisant. De plus, elles présentent également des problèmes de confort liés aux moyens de retenue ou de fixation de la chaussure.We know many snowshoes of the type comprising a tubular frame carrying a canvas screen, these rackets being generally snowshoes used in North America. However, these rackets have many drawbacks related to their grip in certain types of terrain and especially in some snow conditions. Indeed, if these rackets are well suited in the terrain requiring great lift such as in fresh snow, they are noticeably lacking in grip on slopes or in terrain where the snow is harder for example. The problems have led some manufacturers to install under the canvas crampons or other knives. However, the results obtained are far to be satisfying. In addition, they also present problems of comfort linked to the means of retaining or fixing the shoe.

La présente invention a pour objectif de résoudre les inconvénients précités à l'aide de moyens simples, fiables, surs et peu compliqués à mettre en oeuvre. Elle a pour objectif de présenter une raquette à neige présentant une grande portance ainsi que des qualités d'accroche importantes permettant à l'utilisateur d'évoluer dans n'importe quel type de terrain et de neige tout en bénéficiant de plus d'un confort accru.The object of the present invention is to resolve the disadvantages mentioned above using simple, reliable, safe and inexpensive means complicated to implement. Its objective is to present a snowshoe with great lift and qualities important grip allowing the user to evolve in any type of terrain and snow while enjoying more increased comfort.

La raquette à neige proprement dite, portant la référence générale (1) est constituée par un cadre (2) délimitant un tamis (4) destiné à recevoir la chaussure de l'utilisateur, ladite chaussure étant retenue sur le tamis par une fixation (7). Le tamis (4) peut être au moins en partie réalisé par une toile (3) dont le bord (3a) est destiné à être fixé en plusieurs endroits au cadre (2), ledit cadre étant formé par au moins une portion de profilé (8a, 8b) constitués par exemple par des tubes (5) avantageusement métallique tel qu'illustré figure 1. Toutefois, il va de soi que les portions de profilés formant le cadre pourraient présenter des profils différents comme le montre les variantes d'exécution illustrées figures 11a, 11b, et 11c, sans pour autant sortir du champ de protection de l'invention.The actual snowshoe, bearing the general reference (1) is constituted by a frame (2) delimiting a screen (4) intended to receive the user's shoe, said shoe being retained on the sieve by a fixing (7). The screen (4) can be at least partially produced by a canvas (3) whose edge (3a) is intended to be fixed in several places in the frame (2), said frame being formed by at least one section portion (8a, 8b) constituted for example by tubes (5) advantageously metallic as illustrated in FIG. 1. However, it goes without saying that the sections of profiles forming the frame could have different profiles as shown in the illustrated variants Figures 11a, 11b, and 11c, without departing from the protective field of the invention.

Selon les modes de réalisations illustrés de la raquette à neige (1) selon l'invention, celle-ci présente un plan longitudinal de symétrie (P), le cadre (2) est avantageusement de type tubulaire comportant ainsi deux portions de tubes latéraux (8a, 8b) reliés à l'avant (AV) par une portion de tube avant (9) prolongeant les tubes latéraux et formant une spatule (11) avantageusement relevée, et reliés à l'arrière (AR) par deux portions de tube arrière (10a, 10b) qui prolongent les tubes latéraux et se rejoignent à l'arrière, les extrémités desdits tubes arrières étant fixées ensemble par un embout de queue (12). Les tubes latéraux bordent ainsi une zone du tamis appelée zone centrale et qui est destinée à être occupée par la chaussure de l'utilisateur comme le montrent les figures 2 et 3. According to the illustrated embodiments of the snowshoe (1) according to the invention, the latter has a longitudinal plane of symmetry (P), the frame (2) is advantageously of tubular type thus comprising two portions of lateral tubes (8a, 8b) connected at the front (AV) by a portion of front tube (9) extending the side tubes and forming a spatula (11) advantageously raised, and connected to the rear (AR) by two portions rear tube (10a, 10b) which extend the side tubes and are join at the rear, the ends of said rear tubes being fixed together by a tail end piece (12). The side tubes thus border an area of the sieve called the central area and which is intended to be occupied by the user's shoe as shown in Figures 2 and 3.

Selon l'invention, la raquette à neige comporte une pièce centrale technique de base (15) réalisée en matériau rigide comme par exemple en matière plastique ou en aluminium, ladite pièce permettant entre autre d'augmenter avantageusement la portance et les caractéristiques d'accroche de la raquette à neige. La pièce centrale technique de base (15) est avantageusement disposée entre les deux portions de tube latéraux (8a, 8b) dans la zone centrale du tamis (4) correspondant à la zone occupée par la chaussure comme le montre les figures 4a et 4b.According to the invention, the snowshoe comprises a central part basic technique (15) made of rigid material such as for example made of plastic or aluminum, said part allowing inter alia advantageously increase the lift and the characteristics snowshoe grip. The basic technical centerpiece (15) is advantageously disposed between the two tube portions lateral (8a, 8b) in the central zone of the screen (4) corresponding to the area occupied by the shoe as shown in Figures 4a and 4b.

Selon l'invention, la pièce centrale technique de base (15) occupe uniquement la zone centrale (80b) du tamis (4), c'est à dire la zone occupée par la chaussure, elle laisse libre les zones avant (80a) et arrière (80c) comme le montre les différents modes de réalisations et variantes d'exécutions, et notamment celles illustrées figures 12a, 12b et 12c. Les zones avant et arrière sont avantageusement occupées par une toile (3) de manière à augmenter sensiblement la portance de la raquette à neige. La pièce centrale technique de base (15) est une pièce rigide indépendante destinée à être fixée au cadre (2) grâce à des moyens de verrouillage par exemple comme le montre le premier mode de réalisation et ses variantes, ou fixée directement par surmoulage tel qu'illustré dans le deuxième mode de réalisation.According to the invention, the basic technical central part (15) occupies only the central area (80b) of the screen (4), i.e. the area occupied by the shoe, it leaves the front (80a) and rear areas free (80c) as shown by the different embodiments and variants of executions, and in particular those illustrated in FIGS. 12a, 12b and 12c. The front and rear areas are advantageously occupied by a canvas (3) of so as to significantly increase the lift of the snowshoe. The basic technical central part (15) is an independent rigid part intended to be fixed to the frame (2) by means of locking by example as shown in the first embodiment and its variants, or fixed directly by overmolding as illustrated in the second embodiment.

Selon le premier mode de réalisation de la raquette à neige selon l'invention, la pièce centrale technique de base (15) se présente sous la forme d'une plaque ajourée dont les bords latéraux (15a, 15b) sont formés par deux parois latérales destinées à se positionner contre les tubes latéraux (8a, 8b) du cadre (2) et avantageusement contre la paroi périphérique interne (PPI) de ceux-ci, c'est à dire contre la paroi située vers l'intérieur du tamis (4) par rapport au plan vertical médian (M) des tubes (5). Notons que la face externe des parois latérales présente au moins en partie une forme complémentaire de celle de ladite paroi périphérique interne du tube contre laquelle elle vient se fixer.According to the first embodiment of the snowshoe according to the invention, the basic technical central part (15) is presented under the form of an openwork plate whose lateral edges (15a, 15b) are formed by two side walls intended to be positioned against side tubes (8a, 8b) of the frame (2) and advantageously against the wall internal peripheral (PPI) of these, i.e. against the wall located towards the inside of the screen (4) with respect to the median vertical plane (M) of the tubes (5). Note that the outer face of the side walls present at less in part a shape complementary to that of said wall internal device of the tube against which it is fixed.

Ainsi, selon ce premier mode de réalisation de la raquette à neige et comme le montre la figure 5, la pièce technique de base (15) présente au niveau de ses bords latéraux (15a, 15b) un profil hémicylindrique ouvert vers l'extérieur complémentaire du profil du tube (5), ledit profil complémentaire étant destiné à prendre appui sensiblement contre l'intégralité de la paroi périphérique interne (PPI) du tube. Il va de soi que lesdits bords latéraux pourraient présenter un profil cylindrique légèrement réduit symétrique par rapport au plan horizontal médian des portions de tube (8a, 8b) de la raquette (1). Il va de soi que la pièce centrale technique de base pourrait venir coopérer de manière différente contre les portions de tubes latéraux du cadre comme par exemple en étant également fixé contre la paroi périphérique externe comme le montre le deuxième mode de réalisation illustré figures 9a, 9b et 10, sans pour autant sortir du champ de protection de l'invention.Thus, according to this first embodiment of the snowshoe and as shown in Figure 5, the basic technical part (15) presents at its lateral edges (15a, 15b) a semi-cylindrical profile open to the outside complementary to the profile of the tube (5), said profile complementary being intended to bear substantially against the entire internal peripheral wall (PPI) of the tube. It is obvious that said side edges could have a cylindrical profile slightly reduced symmetrical with respect to the median horizontal plane of tube portions (8a, 8b) of the racket (1). It goes without saying that the room basic technical center could come to cooperate in a different way against the portions of side tubes of the frame such as for example also being fixed against the outer peripheral wall as the shows the second embodiment illustrated in Figures 9a, 9b and 10, without however, depart from the scope of the invention.

Selon le premier mode de réalisation de la raquette à neige selon l'invention, la fixation (7) de la raquette à neige (1) est disposée sur la face supérieure (65a) de la pièce centrale technique de base (15) et est avantageusement constituée par une plaque (7a) articulée autour d'un axe transversal (XX') par rapport à ladite pièce technique, la plaque (7a) portant des moyens de retenue avant (16) et des moyens de retenue arrières (17) destinés à retenir la chaussure de l'utilisateur.According to the first embodiment of the snowshoe according to the invention, the attachment (7) of the snowshoe (1) is disposed on the upper face (65a) of the basic technical central part (15) and is advantageously constituted by a plate (7a) articulated around an axis transverse (XX ') relative to said technical piece, the plate (7a) bearing front retaining means (16) and retaining means rear (17) for retaining the user's shoe.

Il est important de noter que, selon le premier mode de réalisation illustré figure 5, la toile (3) constituant au moins en partie le tamis (4) est située dans un plan horizontal (H1) situé au-dessus du plan horizontal (H2) contenant la face supérieure de la pièce centrale technique de base (15). Ainsi la pièce technique (15) est au moins en partie cachée par la toile (3) lorsque que l'on regarde la raquette (1) par sa face supérieure. Toutefois, la toile (3) présente avantageusement des jours (58) qui permettent d'apercevoir la pièce technique (15). Certaines parties de ladite pièce technique de base disposés dans lesdits jours (58) présentent leur surface supérieure dans le plan (H1) de la toile ou dans un plan situé au dessus dudit plan (H1). Ces parties sont par exemple une paroi d'appui arrière (59) des saillies latérales (20a, 20b, 20c, 20d) ou les logements d'articulations (21a, 21b) dans lesquels des portions d'axe solidaires de la plaque articulée (7a) sont destinés à être introduits afin d'obtenir l'articulation de la fixation autour de l'axe transversal (XX') comme le montrent les figures 2, 3 et 4a. It is important to note that, according to the first mode of embodiment illustrated in Figure 5, the fabric (3) constituting at least partially the sieve (4) is located in a horizontal plane (H1) located above the plane horizontal (H2) containing the upper face of the central part basic technique (15). Thus the technical part (15) is at least in part hidden by the canvas (3) when looking at the racket (1) by its upper side. However, the fabric (3) advantageously has days (58) which allow to see the technical part (15). Some parts of said basic technical part disposed in said days (58) have their upper surface in the plane (H1) of the canvas or in a plane located above said plane (H1). These parts are for example a rear support wall (59) of the lateral projections (20a, 20b, 20c, 20d) or the joint housings (21a, 21b) in which axis portions integral with the articulated plate (7a) are intended to be introduced so to obtain the articulation of the fixing around the transverse axis (XX ') as shown in Figures 2, 3 and 4a.

Selon le premier mode de réalisation de la raquette à neige (1), les logements d'articulation (21a, 21b) sont disposés à l'extrémité avant de la pièce centrale technique de base (15) à l'arrière d'un jour (58a) de la toile (3) de taille suffisante pour permettre le pivotement de l'extrémité avant de la plaque (7a) qui est munie de la chaussure de l'utilisateur.According to the first embodiment of the snowshoe (1), the articulation housings (21a, 21b) are arranged at the front end of the basic technical central part (15) at the rear of a day (58a) of the canvas (3) of sufficient size to allow the pivoting of the end front of the plate (7a) which is provided with the user's shoe.

Selon le premier mode de réalisation de la raquette à neige selon l'invention, la pièce centrale technique de base (15) comporte sur sa face inférieure (65b) des moyens d'accroche (MA) destinés à renforcer les caractéristiques d'accroche de la raquette à neige (1) notamment dans le sens transversal. Ces moyens d'accroche peuvent, par exemple, être constitués par des portions de parois longitudinales latérales (18a, 18b) dont au moins une partie de l'arête inférieure (19a, 19b) est disposée dans un plan sensiblement horizontal (H3) situé en dessous du plan horizontal (H4) contenant le bord inférieur du tube dans la zone centrale du cadre (2) tel qu'illustré figure 5. Il va de soi que les moyens d'accroche pourraient également comporter, des crampons, des couteaux ou tout autre moyens d'accroche équivalents sans pour autant sortir du champ de protection de l'invention.According to the first embodiment of the snowshoe according to the invention, the basic technical central part (15) has on its face lower (65b) attachment means (MA) intended to reinforce the grip characteristics of the snowshoe (1) especially in the transverse direction. These attachment means can, for example, be formed by portions of lateral longitudinal walls (18a, 18b) of which at least part of the lower edge (19a, 19b) is arranged in a substantially horizontal plane (H3) located below the plane horizontal (H4) containing the lower edge of the tube in the central area of the frame (2) as illustrated in FIG. 5. It goes without saying that the means of attachment could also include, crampons, knives or any other equivalent means of attachment without leaving the field of protection of the invention.

Notons de plus, que les arêtes inférieures (19a, 19b) des bords de la pièce centrale technique de base (15) peuvent avantageusement être crénelées ou présenter une denture pour renforcer l'accroche de la raquette dans le sens longitudinal. Selon le mode de réalisation illustré, la pièce centrale technique de base (15) comporte des parois d'accroche transversale (40) sur sa face inférieure (15b). Ces parois transversales (40) illustrées figures 5 et 7, dont l'arête inférieure s'étend entre les deux bords latéraux (18a, 18b) sensiblement dans le plan horizontal (H4) pourraient aussi être disposées dans un plan horizontal (H5) non représenté, situé sous le plan horizontal (H4) contenant le bord inférieur du cadre (2), ledit plan (H5) pouvant par exemple être confondu avec le plan horizontal (H3) qui contient les arêtes longitudinales (19a, 19b).Note further that the lower edges (19a, 19b) of the edges of the basic technical central part (15) can advantageously be crenellated or have teeth to strengthen the grip of the racket in the longitudinal direction. According to the illustrated embodiment, the basic technical central part (15) has attachment walls transverse (40) on its underside (15b). These transverse walls (40) illustrated in FIGS. 5 and 7, the lower edge of which extends between the two edges lateral (18a, 18b) substantially in the horizontal plane (H4) could also be arranged in a horizontal plane (H5) not shown, located under the horizontal plane (H4) containing the lower edge of the frame (2), said plane (H5) can for example be confused with the plane horizontal (H3) which contains the longitudinal edges (19a, 19b).

Selon le premier mode de réalisation de la raquette à neige, la pièce centrale technique de base (15) comporte deux parois transversales, l'une étant disposée à l'avant de ladite pièce, sensiblement au niveau de l'articulation de la plaque (7a) tandis que l'autre paroi est disposée à l'arrière sous la paroi d'appui arrière (59) sur laquelle est destinée à venir en appui l'extrémité arrière de la plaque articulée sous le talon de l'utilisateur. Il va de soi que le nombre, la position longitudinale ainsi que la forme des parois d'accroche transversale pourraient être différents sans pour autant sortir du champ de protection de l'invention. De plus, selon ce mode de réalisation, les parois longitudinales latérales (18a, 18b) peuvent être discontinues et constituées chacune de trois portions de parois comme le montre la figure 2. Par ailleurs, selon une variante d'exécution illustrée figure 7, les parois d'accroches latérales (18a, 18b) peuvent être inclinées par rapport au plan longitudinal vertical (P) de référence et présenter par exemple une inclinaison vers l'extérieur (EXT) et vers le bas (BA) par rapport audit plan.According to the first embodiment of the snowshoe, the basic technical center piece (15) has two walls transverse, one being arranged at the front of said piece, substantially at the hinge of the plate (7a) while the other wall is disposed at the rear under the rear support wall (59) on which is intended to bear on the rear end of the hinged plate under the user's heel. It goes without saying that the number, the longitudinal position as well as the shape of the transverse attachment walls could be different without departing from the scope of the invention. In addition, according to this embodiment, the lateral longitudinal walls (18a, 18b) can be discontinuous and each consist of three wall portions as shown in Figure 2. Furthermore, according to a variant shown in FIG. 7, the side hook walls (18a, 18b) can be inclined relative to the vertical longitudinal plane (P) for reference and present for example an inclination towards the outside (EXT) and down (BA) compared to said plan.

Selon le premier mode de réalisation de la raquette à neige selon l'invention, la toile (3) qui constitue au moins en partie le tamis (4) est fixée sur le cadre tubulaire (2) grâce à la pièce centrale technique de base (15) qui permet le coincement du bord de la toile entre ses bords latéraux (15a, 15b) et la paroi périphérique interne (PPI) du tube (5) en plusieurs endroits. De plus, la fixation du cadre tubulaire (2) et de la pièce technique de base (15) ensemble qui permet avantageusement la fixation de la toile peut s'effectuer à l'aide de moyens de verrouillage tels que des rivets qui sollicitent la pièce contre le tube sans ressortir du coté de la paroi périphérique externe du tube.According to the first embodiment of the snowshoe according to the invention, the fabric (3) which at least partially constitutes the screen (4) is fixed to the tubular frame (2) thanks to the basic technical central part (15) which allows the edge of the fabric to be wedged between its edges lateral (15a, 15b) and the internal peripheral wall (PPI) of the tube (5) in several places. In addition, the fixing of the tubular frame (2) and the part basic technique (15) together which advantageously allows fixing canvas can be done using locking means such as rivets which press the part against the tube without coming out from the side of the outer peripheral wall of the tube.

Notons que selon ce premier mode de réalisation la pièce centrale technique de base (15) peut constituer en partie des moyens de fixation de la toile (3) sur le cadre tubulaire (2). Par ailleurs la pièce centrale technique de base (15) comporte des moyens de tension de la toile destinés à permettre à la toile d'être tendue et d'épouser notamment le profil longitudinal de la raquette, ces moyens pouvant être constitués par deux prolongements avants (25a, 25b) qui s'étendent dans la zone avant (80a) de la raquette et sur laquelle la toile peut être rivetée de manière à épouser la forme inclinée ou recourbée de la spatule (11).Note that according to this first embodiment the part basic technical center (15) may partly constitute means of fixing the fabric (3) to the tubular frame (2). Besides the room basic technical center (15) comprises means for tensioning the canvas intended to allow the canvas to be stretched and to marry in particular the longitudinal profile of the racket, these means being able to be constituted by two front extensions (25a, 25b) which extend into the area front (80a) of the racket and on which the canvas can be riveted so as to follow the inclined or curved shape of the spatula (11).

Selon une variante d'exécution de la raquette à neige illustré figures 8a et 8b, les moyens de verrouillage (MV) destinés à permettre la fixation de la pièce centrale technique de base (15) au cadre (2) sont constitués par des piges (50a, 50b, 50c, 50d, 50e, 50f) destinés à coopérer avec des logements complémentaires (51) du tube (5). Selon ce mode de réalisation ladite coopération est due à la sollicitation des portions de tubes latéraux (8a, 8b) du cadre (2) l'un vers l'autre de manière à coincer la pièce centrale technique de base (15), ladite sollicitation pouvant être avantageusement obtenue grâce à l'embout de queue (12) qui permet de fixer ensemble les extrémités libres du tube (5) formant le cadre (2).According to an alternative embodiment of the illustrated snowshoe Figures 8a and 8b, the locking means (MV) intended to allow the fixing the basic technical central part (15) to the frame (2) are constituted by rods (50a, 50b, 50c, 50d, 50e, 50f) intended to cooperate with complementary housings (51) of the tube (5). According to this mode of realization said cooperation is due to the solicitation of portions of side tubes (8a, 8b) of the frame (2) towards each other so as to wedge the basic technical central part (15), said stress being able to be advantageously obtained thanks to the tail end piece (12) which allows fix the free ends of the tube (5) forming the frame (2) together.

Selon le premier mode de réalisation illustré de la raquette à neige (1) selon l'invention, les bords latéraux (15a, 15b) de la pièce centrale technique de base (15) et les portions de tubes latéraux (8a, 8b) du cadre (2) présentent un rétrécissement en largeur (30) dans la zone centrale du tamis (4). Le rétrécissement (30) est avantageusement situé longitudinalement au milieu de la zone centrale destinée à recevoir le pied de l'utilisateur. Il va de soi que les parois d'accroche latérales (18a, 18b) prolongeant vers le bas les bords latéraux (15a, 15b) présentent également un rétrécissement central correspondant ; toutefois il pourrait présenter des parois latérales droites parallèles entre elles sans pour autant sortir du champ de protection de l'invention.According to the first illustrated embodiment of the racket snow (1) according to the invention, the lateral edges (15a, 15b) of the part basic technical unit (15) and the side tube portions (8a, 8b) of the frame (2) have a width narrowing (30) in the area sieve center (4). The narrowing (30) is advantageously located longitudinally in the middle of the central area intended to receive the user's foot. It goes without saying that the lateral attachment walls (18a, 18b) extending downward the side edges (15a, 15b) have also a corresponding central narrowing; however he could have straight side walls parallel to each other without as much to leave the field of protection of the invention.

Selon les mode de réalisation illustrés de la raquette à neige (1) , la pièce centrale technique de base (15) est réalisée en matière plastique par tout procédé de fabrication comme par exemple par moulage, par injection ou par pultrusion. La matière plastique utilisée peut être par exemple constituée par un polyamide ou par un polypropylène.According to the illustrated embodiment of the snowshoe (1), the basic technical center piece (15) is made of plastic by any manufacturing process such as for example by molding, by injection or pultrusion. The plastic used can be example constituted by a polyamide or by a polypropylene.

Selon un deuxième mode de réalisation de la raquette à neige selon l'invention illustrée figures 9a, 9b et 10, la pièce centrale technique de base (15) est réalisée en matière plastique et sa fixation au cadre est obtenue directement par surmoulage sur les profilés latéraux (8a, 8b). Ainsi, comme le montrent les figures 9b et 10, la pièce centrale technique de base (15) est réalisée par injection, de manière à emprisonner le tube (5) qui forme le cadre (2) à l'intérieur de manchons cylindriques en au moins deux points de fixation et avantageusement quatre (70a, 70b, 70c, 70d). Notons que, selon ce mode de réalisation, les deux points de fixation latéraux sont disposés de part et d'autres du rétrécissement en largeur (30) de la zone centrale, les points de fixation avant (70a, 70b) étant positionnés longitudinalement au niveau de l'axe d'articulation (XX') de la fixation (7) et les points arrières (70c, 70d) à l'extrémité arrière de la zone centrale (80b). Il va de soi que le positionnement et le nombre des points de fixation pourraient être différents sans pour autant sortir du champ de protection de l'invention. Ainsi, la fixation pourrait être obtenue par deux manchons latéraux surmoulés autour du tube de part et d'autre de la pièce technique de base sur l'intégralité de sa longueur par exemple. Par ailleurs, il est important de noter, comme le montre en détail la figure 9c, que les manchons (70a, 70b, 70c, 70d) formant les points de fixation présentent des chanfreins latéraux (69a, 69b) de manière à former avec les profilés latéraux (8a, 8b) des angles respectifs (F1, F2) obtus. Ainsi les bords de la raquette ne présentent aucune saillie latérale susceptible de s'accrocher avec un élément extérieur ou avec l'autre raquette lors de la marche.According to a second embodiment of the snowshoe according to the invention illustrated in FIGS. 9a, 9b and 10, the technical central part base (15) is made of plastic and its attachment to the frame is obtained directly by overmolding on the lateral profiles (8a, 8b). Thus, as shown in Figures 9b and 10, the technical centerpiece base (15) is produced by injection, so as to trap the tube (5) which forms the frame (2) inside cylindrical sleeves in au at least two fixing points and advantageously four (70a, 70b, 70c, 70d). Note that, according to this embodiment, the two points of lateral fixings are arranged on both sides of the narrowing in width (30) of the central zone, the front fixing points (70a, 70b) being positioned longitudinally at the level of the articulation axis (XX ') of the fixing (7) and the rear points (70c, 70d) at the end back of the central area (80b). It goes without saying that the positioning and number of fixing points could be different without necessarily go beyond the protective field of the invention. So the fixation could be obtained by two side sleeves overmolded around the tube on either side of the basic technical part on its entirety length for example. Furthermore, it is important to note, as the shows in detail Figure 9c, that the sleeves (70a, 70b, 70c, 70d) forming the fixing points have lateral chamfers (69a, 69b) so as to form angles with the side profiles (8a, 8b) respective (F1, F2) obtuse. Thus the edges of the racket do not no lateral projection likely to catch on an element outside or with the other racket when walking.

Selon le deuxième mode de réalisation de la raquette à neige selon l'invention, la toile (3) n'est plus fixée à la raquette à l'aide de la pièce centrale technique de base, mais elle est fixée au moins en partie directement sur ladite pièce technique. Ainsi, comme le montre la figure 9a, la toile (3) est fixée, par exemple, par des rivets sur la face supérieure (65a) de la pièce centrale technique de base (15) et sur l'embout de queue (12), et est fixée de manière connue en soi en formant un passant, au niveau de la spatule (11). Toutefois, la fixation de la toile à l'avant pourrait s'effectuer sur une pièce complémentaire de fixation avant, rigide et solidaire de la portion de tube avant qui forme la spatule, ladite pièce complémentaire pouvant être fixée sur la spatule par surmoulage.According to the second embodiment of the snowshoe according to the invention, the fabric (3) is no longer fixed to the racket using the basic technical center piece, but it is fixed at least in part directly on said technical part. So, as shown in the figure 9a, the fabric (3) is fixed, for example, by rivets on the upper face (65a) of the basic technical central part (15) and on the end piece tail (12), and is fixed in a manner known per se by forming a loop, at the spatula (11). However, fixing the canvas to the front could be done on a complementary front fixing part, rigid and integral with the portion of front tube which forms the spatula, said additional part which can be fixed on the spatula by overmolding.

Notons, par ailleurs, que la pièce centrale technique de base (15) présente également selon ce deuxième mode de réalisation des portions de parois latérales (18a, 18b) qui s'étendent sous le tamis (4) de la raquette à neige et qui forment les moyens d'accroche de celle-ci. Toutefois, selon ce deuxième mode de réalisation, ces parois sont positionnées avantageusement sous les manchons cylindriques latéraux de la pièce centrale technique de base qui emprisonnent le tube et qui forment les points de fixation (70a, 70b, 70c, 70d). Les parois d'accroche (18a, 18b) peuvent ainsi s'étendre vers le bas (BA) le long de ces manchons dans le plan médian (M) du tube (5), comme le montre la figure 10.Note, moreover, that the basic technical central part (15) also according to this second embodiment of the portions side walls (18a, 18b) which extend under the screen (4) of the snowshoe and which form the means of attachment thereof. However, according to this second embodiment, these walls are advantageously positioned under the lateral cylindrical sleeves of the basic technical central part which trap the tube and which form the fixing points (70a, 70b, 70c, 70d). Hanging walls (18a, 18b) can thus extend downwards (BA) along these sleeves in the median plane (M) of the tube (5), as shown in the figure 10.

Selon l'invention, le cadre (2) est formé par un tube (5) unique qui est mis en forme par cintrage, par exemple, et dont les extrémités (5a, 5b) sont fixées ensemble à l'extrémité arrière de la raquette à neige (1) comme le montre la figure 4a. Les moyens de fixation des extrémités des tubes (5a, 5b) peuvent être de tous types. Ils peuvent notamment être obtenus par une pièce d'extrémité arrière ou embout de queue (12) qui emprisonne ensemble les deux extrémités de tube. Ainsi, comme le montrent les figures 13 et 14, l'embout de queue (12) peut avantageusement présenter des moyens d'étanchéité sous la forme de deux saillies cylindriques internes (71) destinées à boucher chaque extrémité des tubes pour empêcher la neige ou l'eau de pénétrer dans ceux-ci. De plus, une fois l'embout de queue (12) emmanché sur l'extrémité des tubes, une pièce complémentaire d'étanchéité et de fixation (72) qui possède la forme d'un coin vient remplir l'espace interne laissé libre de l'embout de queue (12) Cette pièce complémentaire (72) est rivetée, par exemple, à l'embout de queue (12), la fixation par rivet pouvant permettre également la fixation de l'extrémité arrière de la toile (3) sur l'embout de queue (12).According to the invention, the frame (2) is formed by a single tube (5) which is shaped by bending, for example, and whose ends (5a, 5b) are attached together at the rear end of the snowshoe (1) as shown in Figure 4a. The means of fixing the ends tubes (5a, 5b) can be of all types. They can in particular be obtained by a rear end piece or tail end piece (12) which traps the two tube ends together. So like the show Figures 13 and 14, the tail end (12) can advantageously have sealing means in the form of two internal cylindrical projections (71) intended to plug each end of tubes to prevent snow or water from entering these. In addition, once the tail end piece (12) is fitted onto the end of the tubes, a complementary sealing and fixing (72) which has the shape of a corner fills the space internal left free from the tail end (12) This part complementary (72) is riveted, for example, to the tail end piece (12), fixing by rivet can also allow fixing of the rear end of the fabric (3) on the tail end piece (12).

Il est important de noter que la pièce centrale technique de base (15) n'occupe que la zone centrale (80b) du tamis (4) de la raquette à neige (1) et qu'elle laisse intégralement libre la zone avant (80a) correspondant à la spatule et la zone arrière (80c). De ce fait les portions de profilés latéraux (8a, 8b) s'étendent de part et d'autre de la pièce centrale technique de base (15) vers l'avant pour former la spatule et vers l'arrière pour se rejoindre dans l'embout arrière de manière à déterminer une zone avant et une zone arrière entre le cadre et ladite pièce centrale technique de base (15), ces zones laissées libres par la pièce centrale technique de base (15) sont avantageusement occupées par la toile (3).It is important to note that the basic technical centerpiece (15) occupies only the central area (80b) of the screen (4) of the racket snow (1) and that it leaves the front area completely free (80a) corresponding to the spatula and the rear area (80c). Therefore the portions lateral profiles (8a, 8b) extend on either side of the part basic technical center (15) forward to form the spatula and towards the rear to join in the rear end so as to determine a front zone and a rear zone between the frame and said basic technical central part (15), these areas left free by the basic technical central part (15) are advantageously occupied by the canvas (3).

Ainsi, selon les différents modes de réalisation illustrés de la raquette à neige selon l'invention, le cadre est formé par un unique tube dont les extrémités sont fixées ensemble par un embout de queue ; ceci permettant d'éviter les problèmes dus à l'assemblage de plusieurs portions de tube par emmanchage, soudage ou autres, qui occasionnent à l'endroit des raccords des faiblesses, des problèmes de corrosion ou d'étanchéité, par exemple.Thus, according to the various illustrated embodiments of the snowshoe according to the invention, the frame is formed by a single tube the ends of which are fixed together by a tail end; this avoiding problems due to the assembly of several portions of tube by fitting, welding or other, which cause the location of the connections, weaknesses, corrosion problems or sealing, for example.

Par ailleurs, l'invention concerne également un procédé de fabrication d'une raquette à neige du type précédemment décrit. Selon ce procédé, l'étape principale de fabrication de la raquette à neige (1) consiste à réaliser une pièce centrale technique de base (15) en matière rigide comme, par exemple, par un procédé d'injection plastique, ladite pièce étant destinée à pouvoir être montée dans plusieurs cadres tubulaires de dimensions différentes sans modifier ses dimensions propres. De cette manière, le procédé permet d'obtenir une gamme de raquette à neige de taille différente en utilisant une même pièce centrale technique de base afin de réduire notamment les coûts de production en effectuant un seul moule de taille unique pour l'injection plastique de la pièce technique de base qui pourra être utilisé pour fabriquer des raquettes de taille différente. Les figures 12a, 12b, 12c illustrent trois raquettes de longueurs différentes (L1, L2, L3) dont la pièce centrale technique est identique et de longueur L. Ainsi, le procédé consiste également à réaliser par exemple par cintrage, un cadre dont l'espacement des portions de tubes latéraux (8a, 8b) dans la partie centrale est égal à la largeur de la pièce technique de base (15) quelles que soient la forme et les dimensions des autres parties du cadre tubulaire (2). Selon une variante d'exécution du procédé, le moule destiné à réaliser par injection la pièce centrale technique de base est un moule de surmoulage dans lequel on dispose le cadre de la dimension choisie pour effectuer le surmoulage.Furthermore, the invention also relates to a method of manufacture of a snowshoe of the type previously described. According to what process, the main step in making the snowshoe (1) consists in making a basic technical central part (15) in material rigid as, for example, by a plastic injection process, said part intended to be able to be mounted in several frames tubulars of different dimensions without changing its dimensions clean. In this way, the method makes it possible to obtain a range of different size snowshoe using the same center piece basic technique in order to reduce in particular production costs by performing a single one-size-fits-all mold for plastic injection of the basic technical part that can be used to make different size snowshoes. Figures 12a, 12b, 12c illustrate three rackets of different lengths (L1, L2, L3) including the center piece technique is identical and of length L. Thus, the process consists also to be produced for example by bending, a frame whose the spacing of the portions of lateral tubes (8a, 8b) in the part central is equal to the width of the basic technical part (15) which whatever the shape and dimensions of the other parts of the frame tubular (2). According to an alternative embodiment of the method, the mold intended to be produced by injection, the basic technical core part is a mold overmolding in which we have the frame of the chosen dimension to perform overmolding.

Le cadre périphérique (2) donné à titre d'exemple est réalisé par un profilé, tel qu'un tube cylindrique fermé (5), mais il pourrait en être bien entendu tout autrement. Ainsi, le cadre (2) peut être réalisé par tout autre type de profilé, tels que ceux illustrés par exemple aux figures 11a, 11b, 11c.The peripheral frame (2) given by way of example is produced by a profile, such as a closed cylindrical tube (5), but it could be of course everything else. Thus, the frame (2) can be produced by any other type of profile, such as those illustrated for example in FIGS. 11a, 11b, 11c.

Le cadre périphérique (2) est dans l'exécution préférée d'un seul tenant et réalisé par un tube (5) continu conformé, mais on ne sortirait pas du cadre de l'invention s'il était réalisé en plusieurs morceaux ou ne comprenait qu'une ou deux portions de profilé.The peripheral frame (2) is in the preferred embodiment of a single holding and produced by a continuous shaped tube (5), but no one would exit not within the scope of the invention if it were made in several pieces or do not included only one or two profile portions.

On comprendra que la pièce centrale technique de base (15) est une pièce rigide indépendante du cadre (2), qui est fixée à ce cadre par tous moyens comme par rivetage, collage ou surmoulage par exemple.It will be understood that the basic technical central part (15) is a rigid piece independent of the frame (2), which is fixed to this frame by all means such as riveting, gluing or overmolding for example.

Ajoutons que la pièce centrale technique (15) peut être réalisée dans un matériau différent de celui avec lequel est réalisé le cadre. Ainsi selon le mode de réalisation préféré, le cadre est avantageusement un profilé métallique tubulaire, tandis que la pièce centrale est réalisée dans un matériau autre, comme par exemple en matériau plastique. Il va de soi que la pièce centrale pourrait être réalisée dans un autre matériau comme par exemple un matériau métallique tel que l'aluminium, de même le cadre pourrait être réalisé dans un matériau différent tel qu'un matériau composite par exemple sans pour autant sortir du champ de protection de l'invention.Add that the technical central part (15) can be produced in a material different from that with which the frame is made. So according to the preferred embodiment, the frame is advantageously a tubular metal profile, while the central part is made in another material, such as for example plastic material. It is obvious that the center piece could be made of another material such as for example a metallic material such as aluminum, likewise the frame could be made of a different material such as a material composite for example without leaving the protective field of the invention.

Notons que la toile (3) est un matériau souple textile ou une feuille de matière plastique ou une feuille en matériau composite.Note that the canvas (3) is a flexible textile material or a sheet of plastic or sheet of composite material.

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.
