Abstract

The snow shoe has a peripheral wall and walls which define a frame that rests on the snow. Its upper surface has a central longitudinal edge (18) with inclined lateral surfaces (21a,21b) that converge towards the top and the vertical plane of symmetry (P). The inclined surfaces have transversal walls (22a,22b) which extend upwards and extend from a central flat surface (20). They are perpendicular to the plane of symmetry. The boot, or its bindings, rests on the upper surface of the transversal walls.

Description

La présente invention concerne une raquette à neige et plus particulièrement un perfectionnement pour sa zone centrale qui en améliore les performances et le confort.The present invention relates to a snowshoe and more particularly an improvement for its central area which improves performance and comfort.

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 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 athletes who go on hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the material they use, and it is true that the products currently sold are not entirely satisfactory.

En effet, lors de sa progression, à chacun de ses pas, l'utilisateur lève son talon par pivotement de la chaussure autour d'un axe transversal et l'espace ainsi libéré sous la chaussure se trouve vite rempli de neige qui est ainsi prisonnière et constamment tassée par les mouvements perpétuels du pied qui, après s'être levé, est ramené sur la raquette. Il s'en suit qu'une accumulation de neige tassée finit par ne plus permettre au talon de l'utilisateur d'être ramené correctement sur la raquette. On dit que la neige "botte", et ledit utilisateur doit en permanence s'arrêter pour retirer cette neige tassée qui finirait même par provoquer la rupture de la raquette ou de la fixation. On comprend donc pourquoi il est nécessaire de remédier à cet inconvénient et c'est l'objet de la présente invention.Indeed, during his progress, at each of his steps, the user lifts his heel by pivoting the shoe around a transverse axis and the space thus freed up under the shoe is quickly filled with snow which is thus trapped and constantly compacted by movements perpetual of the foot which, after having risen, is brought back on the racket. They follows that an accumulation of packed snow ends up no longer allowing the heel of the user to be correctly brought back on the racket. One says that the snow "kicks", and said user must constantly stop for remove this packed snow that would even cause the breakage of the racket or binding. So we understand why it is necessary to overcome this drawback and this is the object of the present invention.

La présente invention propose une nouvelle raquette dont la partie centrale où se trouve la chaussure de l'utilisateur présente une arête centrale d'appui permettant à la neige d'être évacuée latéralement tout en procurant à la chaussure un bon appui sur la raquette. The present invention provides a new racket, the central part where the user's shoe is located has an edge support center allowing snow to be evacuated laterally while providing the shoe with good support on the racket.

Ainsi selon l'invention, la raquette à neige, qui a la forme d'une plaque comprenant un ensemble de parois constituant le tamis, destinée à s'appuyer sur la neige et à supporter la chaussure de l'utilisateur, est caractérisée en ce que le tamis comprend dans la zone centrale occupée par la chaussure une arête longitudinale qui comprend au moins une surface latérale inclinée convergente vers le haut avec le plan de symétrie générale.Thus according to the invention, the snowshoe, which has the shape of a plate comprising a set of walls constituting the sieve, intended to lean on the snow and support the user's shoe, is characterized in that the sieve comprises in the occupied central zone by the shoe a longitudinal edge which comprises at least one inclined lateral surface converging upwards with the plane of symmetry general.

Selon une caractéristique complémentaire, la surface inclinée comprend une succession de saillies s'étendant vers le haut.According to an additional characteristic, the inclined surface includes a succession of upwardly extending projections.

Dans une disposition préférée, les saillies sont constituées par ces parois transversales, dont la bordure supérieure sert d'appui pour la chaussure ou la fixation de la chaussure, lesdites parois transversales pouvant être perpendiculaires au plan de symétrie générale, ou en biais par rapport à ce plan.In a preferred arrangement, the projections consist of these transverse walls, the upper edge of which serves as a support for the shoe or the shoe attachment, said transverse walls may be perpendicular to the general plane of symmetry, or at an angle compared to this plan.

Selon un mode de réalisation préféré, l'arête centrale longitudinale comprend une surface d'appui centrale horizontale prolongée latéralement de part et d'autre par une surface longitudinale inclinée, à savoir, une surface inclinée gauche et une surface inclinée droite vers le haut pour former un angle qui peut être compris entre 10 et 170°, tandis que chacune desdites surfaces inclinées latérales comprend une succession de saillies.According to a preferred embodiment, the central edge longitudinal includes a horizontal central support surface laterally extended on both sides by a longitudinal surface tilted, i.e., a left tilted surface and a tilted surface straight up to form an angle which can be between 10 and 170 °, while each of said lateral inclined surfaces comprises a succession of projections.

La raquette désignée sous la référence générale (1) se présente sous la forme d'une plaque ajourée de plan vertical de symétrie générale (P) fixée sous la chaussure et qui se compose d'un cadre principal (2) constitué d'une paroi périphérique (3) délimitant une zone intérieure ou tamis (4), comprenant un ensemble de parois internes supportant la fixation (5) destinée à retenir la chaussure (6) de l'utilisateur.The racket designated under the general reference (1) is presented in the form of an openwork plate of vertical plane of general symmetry (P) fixed under the shoe and which consists of a main frame (2) consisting of a peripheral wall (3) delimiting an interior area or screen (4), comprising a set of internal walls supporting the binding (5) for retaining the shoe (6) of the user.

Ledit tamis (4) avec son ensemble de parois internes forme une surface inférieure générale d'appui sur la neige permettant à l'utilisateur de ne pas trop s'enfoncer dans la neige et ce, grâce à la surface portante relativement importante. Notons que la fixation (5) destinée à retenir la chaussure (6) est, selon l'illustration donnée à titre d'exemple, articulée par rapport au tamis (4) de la raquette proprement dite, selon un axe transversal (XX') pour pouvoir être pivoté verticalement selon (F1, F2). De façon avantageuse, ladite fixation portant la référence générale (5) est constituée par une plaque articulée (9) comprenant des moyens de retenue pour la chaussure, à savoir des moyens avant (10) et des moyens arrière (11). Ainsi, l'extrémité avant (12) de la chaussure est, par exemple, retenue par un étrier avant (13), tandis que son extrémité arrière (14) l'est, grâce à un étrier arrière pivotant (15) comprenant un levier (16) de retenue. Il va de soi que les moyens de retenue avant et arrière pourraient être inversés, à savoir que, l'étrier avant (13) pourrait être mis à l'arrière et que l'étrier arrière (15) pourrait être mis à l'avant. La plaque (9) est avantageusement rigide et s'étend longitudinalement, comprenant une surface d'appui supérieure (17) pour supporter la semelle de la chaussure. Bien entendu, la raquette de l'invention peut être équipée de tout autre type de dispositif de fixation de la chaussure comme, par exemple, celui décrit dans la demande française de brevet n° 94 05919 du demandeur.Said screen (4) with its set of internal walls forms a general lower surface of support on snow allowing the user not to sink too far into the snow thanks to the bearing surface relatively large. Note that the fixing (5) intended to retain the shoe (6) is, according to the illustration given by way of example, articulated relative to the sieve (4) of the racket itself, along an axis transverse (XX ') to be able to be pivoted vertically according to (F1, F2). Advantageously, said attachment bearing the general reference (5) is constituted by an articulated plate (9) comprising means for shoe retainer, namely front means (10) and means rear (11). Thus, the front end (12) of the shoe is, for example, retained by a front stirrup (13), while its rear end (14) is, by means of a pivoting rear stirrup (15) comprising a lever (16) of detention. It goes without saying that the front and rear retaining means could be reversed, namely that the front bracket (13) could be put at the rear and that the rear bracket (15) could be put in the front. The plate (9) is advantageously rigid and extends longitudinally, comprising a upper bearing surface (17) for supporting the sole of the shoe. Of course, the racket of the invention can be equipped with any other type of shoe fastening device such as, for example, that described in the French patent application No. 94 05919 of the applicant.

La plaque ajourée a une forme générale allongée dont l'avant est avantageusement relevé et de forme sensiblement pointue pour constituer la spatule avant (8), tandis que sa zone centrale (60) située sous la chaussure (6) du skieur et donc sous la plaque (9), dans le cas d'une fixation telle qu'illustrée aux figures 1 et 2, comprend une arête longitudinale (18) s'étendant, par exemple, depuis l'axe (XX') jusqu'au talon (19) de la raquette. Ladite arête longitudinale (18) sert avantageusement d'appui pour la chaussure (6) ou pour la plaque (9) dans le cas d'une fixation du type de la plaque (9). Ajoutons que l'arête longitudinale (18) comprend une surface d'appui centrale horizontale (20) qui, selon l'invention, est prolongée latéralement de part et d'autre par une surface latérale longitudinale inclinée (21a, 21b), à savoir, une surface inclinée gauche (21a) et une surface inclinée droite (21b). Notons que les deux surfaces inclinées (21a, 21b) sont convergentes vers le haut pour former un angle (α) qui peut être compris entre 10 et 170°.The openwork plate has a generally elongated shape the front of which is advantageously raised and of substantially pointed shape to constitute the front spatula (8), while its central zone (60) located under the shoe (6) of the skier and therefore under the plate (9), in the case of a attachment as illustrated in Figures 1 and 2, includes an edge longitudinal (18) extending, for example, from the axis (XX ') to heel (19) of the racket. Said longitudinal edge (18) serves advantageously of support for the shoe (6) or for the plate (9) in in the case of a fixing of the type of the plate (9). Add that the edge longitudinal (18) comprises a horizontal central bearing surface (20) which, according to the invention, is extended laterally on either side by an inclined longitudinal side surface (21a, 21b), namely, a left inclined surface (21a) and a right inclined surface (21b). Note that the two inclined surfaces (21a, 21b) converge upwards to form an angle (α) which can be between 10 and 170 °.

Selon un mode d'exécution préféré tel que représenté aux figures 1 à 8 chacune des surfaces latérales inclinées (21a, 21b) comprend une succession de saillies respectivement (22a, 22b). Chacune des saillies est constituée par une paroi transversale s'étendant vers le haut de façon à ce que sa bordure supérieure (220) soit dans le même plan que le plan de la surface d'appui centrale (20). Chacune des parois transversales en saillie s'étend perpendiculairement à la surface inclinée, la surface inclinée gauche (21a) comprenant une succession de parois transversales en saillie gauche (22a) tandis que la surface inclinée droite (21b) comprend une succession de parois transversales en saillie droite (22b). Notons que les parois en saillies successives s'étendent avantageusement en biais par rapport au plan général de symétrie (P). En effet, les parois en saillie sont en biais, de façon à ce que les parois gauches (22a) soient convergentes avec les parois droites (22b), de façon à converger vers l'avant (AV). Il va de soi que lesdites parois (22a, 22b) pourraient aussi converger vers l'arrière (AR).According to a preferred embodiment as shown in the figures 1 to 8 each of the inclined side surfaces (21a, 21b) comprises a succession of projections respectively (22a, 22b). Each of the projections is constituted by a transverse wall extending upwards so that that its upper border (220) is in the same plane as the plane of the central support surface (20). Each of the projecting transverse walls extends perpendicular to the inclined surface, the inclined surface left (21a) comprising a succession of transverse walls in left projection (22a) while the right inclined surface (21b) comprises a succession of transverse walls projecting straight (22b). note that the successively projecting walls advantageously extend at an angle relation to the general plane of symmetry (P). Indeed, the projecting walls are at an angle, so that the left walls (22a) are convergent with the straight walls (22b), so as to converge forward (AV). he goes of itself that said walls (22a, 22b) could also converge towards rear (AR).

On ne sortirait pas, bien entendu, du cadre de l'invention si les parois transversales (22a, 22b) étaient perpendiculaires au plan P, comme cela est illustré aux figures 10 et 11.We would not, of course, depart from the scope of the invention if the transverse walls (22a, 22b) were perpendicular to the plane P, as this is illustrated in Figures 10 and 11.

La figure 11 est une vue similaire à la figure 10 montrant une variante d'exécution selon laquelle l'arête centrale longitudinale (18) ne comprend pas de surface horizontale centrale mais seulement deux surfaces latérales inclinées convergentes vers le haut.Figure 11 is a view similar to Figure 10 showing a variant according to which the longitudinal central edge (18) does not includes no central horizontal surface but only two inclined side surfaces converging upwards.

Notons que la largeur (L2) de l'arête centrale est avantageusement constante et sensiblement égale à la largeur de la plaque (9) et/ou de la semelle (60) de la chaussure (6), comme cela apparaít plus particulièrement à la figure 8, mais bien entendu il pourrait en être autrement. Ainsi, la largeur (L2) de l'arête peut être variable pour varier, par exemple, progressivement en diminuant vers l'arrière. Ajoutons aussi que la largeur (L1) de la surface centrale d'appui (20) peut être soit constante soit variable.Note that the width (L2) of the central edge is advantageously constant and substantially equal to the width of the plate (9) and / or the sole (60) of the shoe (6), as appears more particularly in Figure 8, but of course it could be other. Thus, the width (L2) of the edge can be variable to vary, for example, gradually decreasing backwards. Let's also add that the width (L1) of the central bearing surface (20) can be either constant be variable.

Dans les illustrations qui ont été données, les deux surfaces inclinées (21a, 21b) sont disposées symétriques, mais il pourrait en être autrement sans pour autant sortir du cadre de l'invention et notamment comme selon l'illustration de la figure 13. In the illustrations that have been given, the two surfaces inclined (21a, 21b) are arranged symmetrical, but there could be otherwise without departing from the scope of the invention and in particular as shown in Figure 13.

Les figures 13 et 14 sont des vues illustrant deux variantes d'exécution possible selon lesquelles l'arête (18) ne comprend qu'une seule surface latérale inclinée convergeant avec le plan de symétrie générale (P).Figures 13 and 14 are views illustrating two variants possible execution according to which the edge (18) comprises only one single inclined lateral surface converging with the plane of symmetry general (P).

Ajoutons que les surfaces latérales inclinées qui sont dans les modes de réalisation constitués par des surfaces planes, pourraient être tout aussi bien constituées par des surfaces courbes, convexes ou concaves, comme cela est illustré aux figures 15 (surfaces convexes) et 16 (surfaces concaves). Notons aussi que le plan de l'arête centrale s'étend avantageusement parallèlement au plan de symétrie générale (P). Toutefois, il pourrait en être autrement et l'arête pourrait très bien être disposée en biais par rapport au plan (P). Par ailleurs, la ou les surface(s) latérale(s) pourrai(en)t être solidaire(s) des pièces latérales rapportées sur la raquette, sans pour autant que l'on sorte du cadre de l'invention. Notons aussi que l'arête peut être solidaire du tamis et/ou solidaire du cadre.Let us add that the inclined lateral surfaces which are in the embodiments consisting of flat surfaces, could be equally well formed by curved, convex or concave, as shown in Figures 15 (convex surfaces) and 16 (concave surfaces). Note also that the plane of the central edge extends advantageously parallel to the general plane of symmetry (P). However, it could be otherwise and the edge could very well be arranged at an angle to the plane (P). In addition, the surface (s) side (s) could be attached to the side pieces on the racket, without departing from the scope of the invention. Note also that the edge may be integral with the screen and / or integral with the frame.
