Description

La présente invention concerne un perfectionnement pour raquette à neige destiné notamment à améliorer le confort de la marche en raquette, ainsi que l'accroche de celle-ci dans certains types de neige.The present invention relates to an improvement for snowshoe designed in particular to improve the comfort of walking snowshoeing, as well as the grip of it in certain types of snow.

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 are gear known since very many years because used for centuries by the Scandinavian populations to move on the snow. Until our days, snowshoes were used for utilitarian or military purposes, to allow people and alpine troops to move on the snow for their movements necessitated by everyday life. Currently, snowshoes are used by athletes who go on hikes and walks, or even competitions. But the 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 are not entirely satisfactory.

Ainsi, les raquettes à neige doivent combiner des critères d'accroche et de portance, tout en conservant un confort maximum pour leurs utilisateurs. Par ailleurs, selon les différentes neiges rencontrées, la portance de la raquette nécessaire pour permettre une marche agréable peut s'avérer différente. De même, selon les différents terrains rencontrés, la forme générale la mieux adaptée de la raquette peut être également différente. De ce fait, chaque raquette est généralement performante pour certaines conditions de neige et de pente et est souvent moins performante pour d'autres conditions.Thus, snowshoes must combine criteria of grip and lift, while maintaining maximum comfort for their users. Moreover, according to the different snow encountered, lift of the racket necessary to allow a pleasant walk may be different. Similarly, according to the different terrains encountered, the most suitable general shape of the racket can also be different. As a result, each racket is generally good for some snow and slope conditions and is often less performing for other conditions.

Des raquettes a neige présentant des systèmes d'accroche sur neige sont divulguées par US-A-4 351 121 et EP-A-0 882 478.Snowshoes with snow grip systems are disclosed in US-A-4,351,121 and EP-A-0 882 478.

Ainsi, le critère d'accroche est un critère prépondérant pour les raquettes à neige, et les raquettes de l'art antérieur présentent des inconvénients dans certains types de neige liés à leur manque d'accroche, notamment dans le sens longitudinal et transversal.Thus, the criterion of attachment is a preponderant criterion for snowshoes, and snowshoes of the prior art exhibit disadvantages in some types of snow related to their lack hanging, especially in the longitudinal and transverse direction.

La présente invention a pour but de remédier aux inconvénients précités à l'aide de moyens simples, fiables, peu onéreux et efficaces. La raquette à neige, selon l'invention a pour objectif d'améliorer l'accroche de celle-ci dans tout type de neige, de manière à augmenter le confort de la marche pour son utilisateur.The present invention aims to overcome the disadvantages with simple, reliable, inexpensive and effective means. The snowshoe, according to the invention aims to improve the grip of it in any type of snow, so as to increase the comfort of walking for his user.

Ainsi, selon sa caractéristique principale, le problème est résolu par la raquette à neige selon la revendication 1.Thus, according to its main characteristic, the problem is solved by the snowshoe according to claim 1.

Selon une autre caractéristique de la raquette à neige, elle comporte deux parois longitudinales d'accroche disposées latéralement et formant les bords latéraux du cadre périphérique, lesdits bords latéraux présentant chacun un rétrécissement en hauteur dans leur zone médiane respective.According to another characteristic of the snowshoe, she has two longitudinal gripping walls disposed laterally and forming the lateral edges of the peripheral frame, said edges sides each having a height shrink in their area respective median.

Selon une caractéristique complémentaire, les rétrécissements en hauteur des bords latéraux du cadre périphérique sont disposés symétriquement par rapport au plan longitudinal médian de la raquette.According to a complementary characteristic, the narrowing height of the lateral edges of the peripheral frame are arranged symmetrically with respect to the median longitudinal plane of the racket.

Par ailleurs, selon le mode de réalisation préféré de la raquette à neige selon l'invention, elle comporte au moins une paroi longitudinale d'accroche intérieure disposée sous le tamis délimité par le cadre périphérique, ladite paroi intérieure présentant au moins un rétrécissement en hauteur dans sa zone médiane.Moreover, according to the preferred embodiment of the racket to snow according to the invention, it comprises at least one longitudinal wall inside hook arranged under the sieve delimited by the frame device, said inner wall having at least one shrinkage in height in its median zone.

Selon ce mode de réalisation, la raquette à neige comporte deux parois longitudinales intérieures, chacune des parois intérieures d'accroche présentant de manière symétrique par rapport au plan longitudinal médian, deux rétrécissements en hauteur séparés par un élargissement de paroi.According to this embodiment, the snowshoe has two inner longitudinal walls, each of the inner walls hooks symmetrically with respect to the plane medial length, two narrowing in height separated by a wall widening.

Selon une caractéristique complémentaire de la raquette à neige selon l'invention, celle ci est caractérisée en ce que la position du (des) rétrécissement(s) en hauteur de la paroi longitudinale intérieure est décalée longitudinalement par rapport à la position des rétrécissements en hauteur des parois d'accroche latérales.According to a complementary feature of the snowshoe according to the invention, it is characterized in that the position of narrowing (s) in height of the inner longitudinal wall is offset longitudinally from the position of the narrowing in height of the walls of attachment lateral.

Selon une variante d'exécution de la raquette à neige selon l'invention, la position des élargissements de paroi des parois intérieures est décalée longitudinalement vers l'avant de la raquette par rapport à celle des rétrécissements des parois d'accroche latérales.According to an alternative embodiment of the snowshoe according to the invention, the position of the wall widening of the inner walls is shifted longitudinally forward of the racket relative to that of the narrowing of the lateral attachment walls.

Selon une caractéristique complémentaire de la raquette à neige, le rétrécissement en hauteur est obtenu en faisant varier longitudinalement par rapport au plan horizontal du tamis l'inclinaison et/ou la courbure de l'arête inférieure de la (des) paroi(s) d'accroche longitudinale(s).According to a complementary feature of the snowshoe, shrinkage in height is obtained by varying longitudinally in relation to the horizontal plane of the sieve the inclination and / or the curvature of the lower edge of the wall (s) of attachment longitudinal (s).

Selon une autre caractéristique de la raquette à neige, le rapport entre la hauteur de rétrécissement et la hauteur maximum respective mesurée dans la partie avant ou arrière de la paroi d'accroche est compris entre 0,1 et 0,9.According to another characteristic of the snowshoe, the ratio between the narrowing height and the respective maximum height measured in the front or rear part of the hanging wall is between 0.1 and 0.9.

  • La raquette à neige désignée sous la référence générale (1) est du type comportant un cadre périphérique (2) qui délimite un tamis (4) destiné à supporter la fixation (5) dans laquelle sera retenue la chaussure (6) de l'utilisateur. Le tamis (4) est constitué avantageusement par une plaque ajourée, par exemple, mais pourrait également être constitué par une toile ou des lanières destinée(s) à conférer la portance nécessaire à la raquette à neige (1). La raquette à neige selon l'invention comporte un ensemble de parois longitudinales d'accroche (3a, 3b, 50a, 50b) qui s'étendent vers le bas (BA) sensiblement verticalement sous le plan horizontal (H) du tamis (4). Lesdites parois peuvent par exemple constituer les bords latéraux (3a, 3b) du cadre périphérique comme le montrent les figures 1 à 7, ou être disposées à l'intérieur du cadre sous le tamis (4) pour former des parois longitudinales d'accroche intérieure (50a, 50b), comme le montre le mode de réalisation préféré illustré figures 8 à 10d. Selon l'invention, au moins une des parois longitudinales d'accroche (3a, 3b, 50a, 50b) présente dans la zone médiane (B) de la raquette un rétrécissement en hauteur (100) de sa paroi verticale par rapport à la partie avant (7a) et à la partie arrière (7b) de ladite zone, la zone médiane étant celle située longitudinalement au niveau de la zone occupée par la chaussure (6) de l'utilisateur.The snowshoe designated under the general reference (1) is type having a peripheral frame (2) defining a sieve (4) intended to support the attachment (5) in which the shoe will be retained (6) of the user. The screen (4) is advantageously constituted by a perforated plate, for example, but could also be constituted by canvas or straps to provide the necessary lift for the snowshoe (1). The snowshoe according to the invention comprises a set of longitudinal hooking walls (3a, 3b, 50a, 50b) which extend downward (BA) substantially vertically below the plane horizontal (H) of the sieve (4). Said walls can for example constitute the lateral edges (3a, 3b) of the peripheral frame as the FIGS. 1 to 7, or be arranged inside the frame under the sieve (4) to form longitudinal walls of interior grip (50a, 50b), as shown in the illustrated preferred embodiment Figures 8 to 10d. According to the invention, at least one of the longitudinal walls (3a, 3b, 50a, 50b) present in the central zone (B) of the snowshoe a shrinkage in height (100) of its vertical wall by relative to the front part (7a) and to the rear part (7b) of said area, the middle zone being the one situated longitudinally at the level of the zone occupied by the shoe (6) of the user.

    Selon un premier mode de réalisation de la raquette à neige selon l'invention, celle-ci présente un plan longitudinal de symétrie générale (P) et comporte deux parois d'accroche qui forment les bords latéraux (3a, 3b) du cadre périphérique (2), ce que montrent les figures 1 à 3c. Les parois d'accroche latérales (3a, 3b) présentent chacune un rétrécissement en hauteur (100) dans leur zone médiane (B), lesdits rétrécissements étant identiques et disposés symétriquement par rapport au plan (P). Il va de soi que les rétrécissement en hauteur pourraient être disposés différemment, de même la raquette à neige pourrait par exemple présenter une forme dissymétrique sans pour autant sortir du champs de protection revendiqué.According to a first embodiment of the snowshoe according to the invention, the latter has a longitudinal plane of symmetry (P) and has two hanging walls that form the edges sides (3a, 3b) of the peripheral frame (2), as shown in FIGS. at 3c. The lateral attachment walls (3a, 3b) each have a shrinkage in height (100) in their median zone (B), said shrinkage being identical and arranged symmetrically with respect in the plane (P). It goes without saying that shrinkage in height could be arranged differently, so the snowshoe could by example present an asymmetrical shape without leaving the claimed protection fields.

    Selon l'invention, les rétrécissements (100) sont avantageusement obtenus en faisant varier longitudinalement l'inclinaison et/ou la courbure de l'arête inférieure (60) des parois d'accroche longitudinale (3a, 3b, 50a, 50b) par rapport au plan horizontal (H), l'arête supérieure (61) étant parallèle audit plan ou confondue avec celui-ci. Il va de soi, comme le montre une variante d'exécution illustrée figure 4, que l'arête supérieure (61) pourrait également présenter une inclinaison ou une courbure par rapport au plan horizontal (H) sans pour autant sortir du champ de protection de l'invention, la courbure de l'arête supérieure pouvant être orientée de la même manière que celle de l'arête inférieure, mais de moindre amplitude ou orientée de manière inverse et ceci de manière à obtenir, quelque soit l'orientation de la courbure choisie, le rétrécissement en hauteur voulu.According to the invention, the constrictions (100) are advantageously obtained by longitudinally varying the inclination and / or curvature of the lower edge (60) of the longitudinal attachment walls (3a, 3b, 50a, 50b) relative to the horizontal plane (H), the upper edge (61) being parallel to or coincident with said plane. It is obvious, as shown in an embodiment variant illustrated in FIG. 4, that the ridge upper section (61) could also have an inclination or curvature relative to the horizontal plane (H) without leaving the protection field of the invention, the curvature of the upper edge which can be oriented in the same way as that of the lower edge, but of lesser amplitude or reversed orientation and this of in order to obtain, whatever the orientation of the curvature chosen, the shrinkage in desired height.

    Selon le premier mode de réalisation de la raquette à neige, le rétrécissement (100) en hauteur des parois latérales (3a, 3b) du cadre (2) est avantageusement situé sensiblement dans la portion centrale de la zone médiane (B). Toutefois, il pourrait, par exemple, être décalé vers l'avant ou l'arrière par rapport au milieu de ladite zone, sans pour autant sortir du champ de protection de l'invention. Par ailleurs, le rétrécissement (100) présente avantageusement une forme courbe sur l'une ou les deux arêtes (60, 61) des parois (3a, 3b). Le rétrécissement (100) pourrait également selon une variante illustrée figure 7 être obtenu avec deux portions d'arête inférieure (60) droites et inclinées formant un angle (A) ouvert vers le bas entre elles.According to the first embodiment of the snowshoe, the shrinking (100) in height of the side walls (3a, 3b) of the frame (2) is advantageously located substantially in the central portion of the middle zone (B). However, it could, for example, be shifted to the front or the back relative to the middle of the said zone, without to leave the field of protection of the invention. Moreover, narrowing (100) advantageously has a curved shape on one or both edges (60, 61) of the walls (3a, 3b). Shrinkage (100) could also according to a variant shown in Figure 7 be obtained with two straight and sloping lower edge portions (60) forming a angle (A) open down between them.

    Selon une variante d'exécution de la raquette à neige selon l'invention, la raquette à neige (1) possède un rétrécissement (100a, 100b) sur chacun de ses bords latéraux (3a, 3b) dont le positionnement longitudinal est dissymétrique par rapport au plan (P), comme le montre la figure 6. Notons que selon cette variante d'exécution, les deux raquettes d'une même paire peuvent être identiques et posséder le rétrécissement du bord latéral droit devant le rétrécissement du bord latéral gauche, par exemple. Toutefois, il pourrait en être autrement et les rétrécissements pourraient être inversés, une raquette étant prévue pour le pied gauche et l'autre spécifiquement pour le pied droit, des moyens d'identification étant alors prévus pour permettre de les différencier. Il va de soi que ces raquettes pourraient posséder un profil asymétrique par exemple.According to an alternative embodiment of the snowshoe according to the invention, the snowshoe (1) has a narrowing (100a, 100b) on each of its lateral edges (3a, 3b) whose positioning longitudinal axis is asymmetrical with respect to the plane (P), as shown Figure 6. Note that according to this variant of execution, the two rackets of the same pair may be identical and possess the narrowing of the right lateral edge in front of the narrowing of the left lateral edge, by example. However, it could be different and the narrowing could be reversed, a racket being provided for the left foot and the other specifically for the right foot, means of identification being then planned to allow to differentiate them. It goes without saying that these snowshoes could have an asymmetrical profile for example.

    Par ailleurs, comme le montrent les figures 5a et 5b, la raquette à neige pourrait n'être munie que d'un seul rétrécissement en hauteur (100) situé sur un bord latéral (3a) du cadre (2). Notons que selon cette variante d'exécution, le tamis (4) s'étend latéralement au-delà des bords latéraux (3a, 3b) du cadre périphérique (2) contrairement au premier mode de réalisation illustré figures 3a à 3c, où les bords latéraux (3a, 3b) du cadre (2) forment la limite du tamis (4). Il va de soi qu'il pourrait en être de même dans les autres modes de réalisation de la raquette à neige selon l'invention.Moreover, as shown in FIGS. 5a and 5b, the snowshoe snow could only have one narrowing in height (100) located on a lateral edge (3a) of the frame (2). Note that according to this variant of execution, the sieve (4) extends laterally beyond the lateral edges (3a, 3b) of the peripheral frame (2) contrary to the first mode of embodiment illustrated in FIGS. 3a to 3c, where the lateral edges (3a, 3b) of the frame (2) form the sieve boundary (4). It goes without saying that it could be even in the other embodiments of the snowshoe according to the invention.

    Selon le mode de réalisation préféré de la raquette à neige selon l'invention illustré figures 8 à 10f, celle-ci comporte avantageusement des parois longitudinales d'accroche intérieures (50a, 50b) qui s'étendent sous le tamis (4) sensiblement verticalement. Ces parois d'accroche intérieures (50a, 50b) sont avantageusement au nombre de deux et sont disposées de part et d'autre du plan général de symétrie (P) sensiblement à l'aplomb des bords latéraux de la chaussure (6) de l'utilisateur, et plus précisément à l'aplomb des bords d'une plaque articulée (63) destinée à porter les moyens de retenue (MR) de la chaussure (6) de l'utilisateur. According to the preferred embodiment of the snowshoe according to the invention illustrated in FIGS. 8 to 10f, this advantageously comprises longitudinal interior hanging walls (50a, 50b) extending under the sieve (4) substantially vertically. These hanging walls (50a, 50b) are advantageously two in number and are arranged on either side of the general plane of symmetry (P) substantially in line with the side edges of the user's shoe (6), and more precisely in line with the edges of an articulated plate (63) intended to wear the retaining means (MR) of the shoe (6) of the user.

    Selon ce mode de réalisation, les parois d'accroche latérales (3a, 3b) qui forment les bords du cadre (2), ainsi que les deux parois d'accroche intérieures (50a, 50b) présentent chacune au moins un rétrécissement en hauteur (100a, 100b, 100c, 100d, 100e, 100f). Les parois latérales (3a, 3b) présentent symétriquement un rétrécissement (100a, 100b) situé longitudinalement sensiblement au centre de la zone médiane (B), ce que montre la figure 9. De plus, les parois d'accroche intérieures (50a, 50b) présentent chacune deux rétrécissements en hauteur (100c, 100d, 100e, 100f) disposés successivement dans la zone médiane (B) et séparés entre eux par un élargissement de paroi (200a, 200b), comme le montrent les figures 9, 10a à 10f.According to this embodiment, the lateral attachment walls (3a, 3b) which form the edges of the frame (2), as well as the two walls hooks (50a, 50b) each have at least one shrinkage in height (100a, 100b, 100c, 100d, 100th, 100f). The walls lateral portions (3a, 3b) symmetrically have a narrowing (100a, 100b) located longitudinally substantially in the center of the median zone (B), as shown in Figure 9. In addition, the interior hanging walls (50a, 50b) each have two height restrictions (100c, 100d, 100e, 100f) arranged successively in the central zone (B) and separated from each other by a wall widening (200a, 200b), such as the show Figures 9, 10a to 10f.

    La position longitudinale des rétrécissements (100c, 100d, 100e, 100f) des parois d'accroche intérieures (50a, 50b) est décalée par rapport à celle des rétrécissements centraux (100a, 100b) des parois latérales (3a, 3b) formant le cadre (2). Ainsi, les rétrécissements centraux (100a, 100b) possèdent une position longitudinale qui correspond sensiblement à la position de l'élargissement de paroi (200a, 200b) des parois intérieures. Notons toutefois, que cet élargissement de paroi est avantageusement situé légèrement vers l'avant (AV) de la raquette à neige, par rapport à la position des rétrécissement centraux (100a, 100b) comme l'illustre les figures 10c et 10d.The longitudinal position of the narrowing (100c, 100d, 100th, 100f) inner hanging walls (50a, 50b) is offset relative to to that of central narrowing (100a, 100b) of the side walls (3a, 3b) forming the frame (2). Thus, the central strictures (100a, 100b) have a longitudinal position which corresponds substantially to the position of the wall widening (200a, 200b) of the inner walls. Note, however, that this enlargement of the wall is advantageously located slightly forward (AV) of the snowshoe, compared to the position of central narrowing (100a, 100b) as illustrated by Figures 10c and 10d.

    Selon des variantes d'exécution non représentées, les parois d'accroche intérieures pourraient posséder une configuration différente et ne comporter qu'un seul rétrécissement dont la position longitudinale correspondrait ou serait décalée par rapport à celle des rétrécissements centraux des parois latérales. De même, les parois d'accroche latérales formant le cadre pourraient fort bien ne présenter aucun rétrécissement en hauteur et seules les parois longitudinales intérieures seraient munies de ce type de rétrécissement. Par ailleurs, le nombre de parois d'accroche et leur nombre de rétrécissement pourraient également être très différents sans pour autant sortir du champ de protection de l'invention.According to alternative embodiments not shown, the walls indoor hangers might have a different configuration and have only one narrowing of which the longitudinal position would correspond or be offset from that of the narrowing central side walls. Likewise, the lateral attachment walls forming the frame could very well show no shrinkage in height and only the inner longitudinal walls would be provided of this type of shrinkage. Moreover, the number of walls grip and their shrinkage number could also be very different without departing from the protective field of the invention.

    Selon le mode de réalisation préféré de la raquette à neige selon l'invention, celle-ci est du type décrite dans la demande de brevet français n° 95 03088 de la demanderesse, ses parois d'accroche latérales (3a, 3b) présentant un rétrécissement transversal (250) de leur écartement respectif (d) dans la zone médiane (B) occupée par la chaussure (6) de l'utilisateur. Selon ce mode de réalisation, la position longitudinale de ce rétrécissement transversal (250) correspond avantageusement à celle des rétrécissements en hauteur (100a, 100b) des parois latérales d'accroche (3a, 3b) formant le cadre périphérique (2), l'élargissement (200a, 200b) des parois d'accroche intérieures étant légèrement décalées vers l'avant de la raquette à neige. Il va de soi que le nombre et le positionnement respectifs des différents rétrécissements précités pourraient être différents sans pour autant sortir du champ de protection de l'invention.According to the preferred embodiment of the snowshoe according to the invention, it is of the type described in the patent application French Patent No. 95 03088 of the Applicant, its lateral attachment walls (3a, 3b) having a transverse narrowing (250) of their spacing respective (d) in the middle zone (B) occupied by the shoe (6) of the user. According to this embodiment, the longitudinal position of this transverse narrowing (250) advantageously corresponds to that of shrinkage in height (100a, 100b) of the hanging side walls (3a, 3b) forming the peripheral frame (2), the widening (200a, 200b) interior hanging walls being slightly shifted forward snowshoeing. It goes without saying that the number and positioning respective of the different restrictions mentioned above could be different without departing from the scope of the invention.

    Selon le mode de réalisation préféré de la raquette à neige, les rétrécissements en hauteur (100a, 100b, 100c, 100d, 100e, 100f) sont obtenus en faisant varier la courbure de l'arête inférieure (60) des parois d'accroche longitudinales (3a, 3b, 50a, 50b). Notons que les rétrécissements en hauteur (100c, 100d, 100e, 100f) des parois d'accroche intérieures sont obtenus grâce à une variation plus importante de la courbure de leur arête inférieure par rapport à celle de la courbure des parois latérales, la pente de leur arête inférieure (60) étant de ce fait plus importante.According to the preferred embodiment of the snowshoe, the shrinkage in height (100a, 100b, 100c, 100d, 100th, 100f) are obtained by varying the curvature of the lower edge (60) of the walls longitudinal hooks (3a, 3b, 50a, 50b). Note that shrinkage in height (100c, 100d, 100th, 100f) hanging walls are obtained thanks to a greater variation of the curvature of their lower edge with respect to that of the curvature of side walls, the slope of their lower edge (60) being thus more important.

    Notons également que selon le mode de réalisation préféré de la raquette à neige selon l'invention, les parois d'accroche longitudinales (3a, 3b, 50a, 50b) présentent une arête inférieure (60) dont la forme est arrondie sur l'ensemble de la zone médiane (B), lesdites parois ne présentant ainsi aucune portion d'arête de forme droite.Note also that according to the preferred embodiment of the snowshoe according to the invention, the longitudinal attachment walls (3a, 3b, 50a, 50b) have a lower edge (60) whose shape is rounded over the whole of the median zone (B), said walls do not thus having no straight edge portion.

    Selon le mode de réalisation préféré de la raquette à neige, et comme le montrent les figures 10a à 10f, la hauteur (h1) des rétrécissement (100c, 100d, 100e, 100f) des parois intérieures est identique et est sensiblement égale à la moitié de la hauteur (h2) des élargissements (200a, 200b), toutefois elle pourrait être supérieure ou inférieure à celle-ci sans pour autant sortir du champs de protection de l'invention. Le long de la zone médiane (B), la hauteur desdites parois intérieures est avantageusement comprise entre 0.5 cm et 3 cm. Notons que la hauteur (h3) des rétrécissements (100a, 100b) des parois d'accroche latérales (3a, 3b) est supérieure à la hauteur (h1) des rétrécissement (100c, 100d, 100e, 100f) des parois intérieures, la hauteur desdites parois latérales étant également comprise entre 0.5 cm et 3 cm sur la longueur de la zone médiane (B). Selon le mode de réalisation illustré et comme le montrent les figures 10b et 10e, la hauteur des parois d'accroche latérale (h4) correspondant aux rétrécissements avants (100c, 100d) des parois intérieures (50a, 50b) est supérieure à la hauteur (h5) des mêmes parois latérales (3a, 3b) mesurée au niveau des rétrécissements arrières (100e, 100f). Par ailleurs, on peut noter que les hauteur respectives (h6, h7) des parois d'accroche longitudinales (3a, 3b, 50a, 50b) latérales et intérieures est identique au niveau des extrémités avant (7a) et arrière (7b) de la zone médiane (B), cette hauteur pouvant avantageusement être identique à la hauteur (h2) des élargissements (200a, 200b) tel qu'illustré aux figures 10a, 10d et 10f.According to the preferred embodiment of the snowshoe, and as shown in FIGS. 10a to 10f, the height (h1) of shrinkage (100c, 100d, 100th, 100f) of the interior walls is identical and is substantially equal to half the height (h2) of the enlargements (200a, 200b), however it could be higher or lower than this without departing from the protective field of the invention. Along of the median zone (B), the height of said inner walls is advantageously between 0.5 cm and 3 cm. Note that the height (h3) narrowing (100a, 100b) of the lateral hooking walls (3a, 3b) is greater than the height (h1) of the narrowing (100c, 100d, 100e, 100f) of the inner walls, the height of said sidewalls being also between 0.5 cm and 3 cm along the length of the zone median (B). According to the illustrated embodiment and as shown FIGS. 10b and 10e, the height of the lateral hooking walls (h4) corresponding to the front narrowing (100c, 100d) of the walls interior (50a, 50b) is greater than the height (h5) of the same walls lateral (3a, 3b) measured at the rear narrowing (100th, 100f). Moreover, it can be noted that the respective height (h6, h7) of the longitudinal and lateral gripping walls (3a, 3b, 50a, 50b) is identical at the front (7a) and rear (7b) ends of the middle zone (B), this height can advantageously be identical at the height (h2) of the enlargements (200a, 200b) as illustrated in the figures 10a, 10d and 10f.

    Notons que les modes de réalisation illustrés de la raquette à neige présentent des parois d'accroche longitudinal (3a, 3b, 50a, 50b) sensiblement verticales. Toutefois il pourrait en être autrement comme le montre une variante d'exécution du premier mode de réalisation de la raquette à neige illustrée figures 11a à 11c, les parois latérales d'accroche (3a, 3b) peuvent être inclinées par rapport à la verticale pour s'étendre par exemple vers le bas et l'extérieure du tamis, lesdites parois présentant le ou les rétrécissements en hauteur de l'invention tel qu'illustré figure 11b.Note that the illustrated embodiments of the snowshoe snow have longitudinal hooking walls (3a, 3b, 50a, 50b) substantially vertical. However it could be otherwise like the shows an alternative embodiment of the first embodiment of the Snowshoe illustrated Figures 11a to 11c, the side walls hook (3a, 3b) can be inclined relative to the vertical to extend for example, towards the bottom and the outside of the sieve, said walls presenting the shrinkage or narrowing in height of the invention as illustrated in FIG. 11b.

    De plus, selon cette variante d'exécution de la raquette à neige selon l'invention, l'épaisseur (E) des parois d'accroche longitudinales est variable. La variation de l'épaisseur (E) des parois peut être due à une variation de la courbure de la face interne de la paroi, de la face externe ou des deux faces. Selon cette variante d'exécution, l'épaisseur des parois est variable longitudinalement comme le montre les figures 11a à 11c, toutefois l'épaisseur des parois pourrait également varier transversalement sur la hauteur desdites parois. Comme le montre la figure 11b, les parois latérales d'accroche (3a, 3b) présentent un rétrécissement en épaisseur situé sensiblement à l'endroit du rétrécissement en hauteur (100) desdites parois, toutefois il pourrait en être autrement et les parois pourraient par exemple présenter un élargissement à cet endroit sans pour autant sortir du champs de protection de l'invention.In addition, according to this variant of performance of the snowshoe according to the invention, the thickness (E) of the longitudinal attachment walls is variable. The variation of the thickness (E) of the walls can be due to a variation of the curvature of the internal face of the wall, of the external face or both sides. According to this variant embodiment, the thickness of the walls is longitudinally variable as shown in Figures 11a to 11c, however, the thickness of the walls could also vary transversely on the height of said walls. As shown in FIG. 11b, the lateral attachment walls (3a, 3b) have a narrowing in thickness located substantially at the location of shrinkage in height (100) of said walls, however it could to be otherwise and the walls could for example have a widening to this location without leaving the fields of protection of the invention.

    Selon les différents modes de réalisation illustrés, la raquette à neige présente des parois longitudinales d'accroche dont le profil dans un plan transversal est rectiligne. Toutefois, il pourrait en être autrement et ces parois pourraient présenter des profils recourbés, effilés, ondulés ou autres sans pour autant sortir du champs de protection de l'invention.According to the various illustrated embodiments, the snowshoe snow has longitudinal hanging walls whose profile in a transverse plane is rectilinear. However, it could be otherwise and these walls could have curved, tapered, wavy profiles or others without departing from the scope of the invention.

    Par ailleurs, notons que l'invention est illustrée sur un type de raquette réalisée en matière plastique par injection, cependant, d'autres types de raquettes à neige peuvent être équipées de rétrécissement en hauteur dans la zone médiane de leur cadre comme les raquette possédant un cadre et un tamis en toile ou en lanière par exemple, sans pour autant sortir du champ de protection de l'invention. Le cadre peut être soit tubulaire soit un profil de tout type, et réalisé en aluminium ou autre tel qu'en matière plastique ou en matériau composite.Moreover, note that the invention is illustrated on a type of racket made of plastic by injection, however, other types of snowshoes can be equipped with narrowing in height in the middle area of their frame like snowshoes having a frame and sieve in canvas or thong for example, without however, to leave the field of protection of the invention. The frame can be either tubular or a profile of any type, and made of aluminum or other such as plastic or 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 described and illustrated as examples, but it includes also all technical equivalents as well as their combinations.
