Abstract

The snow shoe covering is fitted over the open inner portion of its frame (2). The snow shoe covering consists of a series of supporting cross-pieces (40). At least one of these pieces is arch-shaped in section and is open towards the bottom (BA). The arch is of varying height, and the cross-pieces which form the covering reduce in with from the centre of the shoe to the frame. The boot fastening is attached to the top of the covering which, alternatively, can have toothed edges for a better grip on ice or snow.

Description

La présente invention concerne une raquette à neige et plus particulièrement un perfectionnement de son tamis.The present invention relates to a snowshoe and more particularly an improvement of its sieve.

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, et notamment lors de la progression sur neige.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, and especially during progression on snow.

La présente invention propose une nouvelle raquette alliant à la fois de bonnes performances en accrochage et en appui au sol, tout en permettant une progression aisée aussi bien dans les montées que dans les descentes.The present invention provides a new racket combining both good performance in hanging and resting on the ground, while allowing an easy progression as well on the climbs as in the descents.

Ainsi, selon l'invention, la raquette à neige comprend un cadre périphérique délimitant une zone intérieure ou tamis constitué par un ensemble de parois internes d'appui et est caractérisé en ce que l'une au moins des parois d'appui s'étend transversalement et est constituée par un profil transversal formant un caisson ouvert vers le bas comprenant au moins une portion de paroi avant s'étendant vers l'avant et vers le bas et une portion de paroi arrière s'étendant vers l'arrière et le bas, les deux portions de paroi étant convergentes vers le haut.Thus, according to the invention, the snowshoe comprises a frame peripheral delimiting an interior zone or sieve constituted by a set of internal support walls and is characterized in that one at less of the support walls extends transversely and is constituted by a transverse profile forming a box open downwards comprising at minus a portion of the front wall extending forward and downward and a rear wall portion extending rearward and downward, both wall portions being converging upwards.

Selon une caractéristique complémentaire, le profil s'étend transversalement et présente un axe général transversal. According to an additional characteristic, the profile extends transversely and has a general transverse axis.

Selon différentes variantes, le profil est symétrique par rapport à son axe général transversal, ou est dissymétrique.According to different variants, the profile is symmetrical with respect to its general transverse axis, or is asymmetrical.

Selon une autre caractéristique, la largeur de la (des) paroi(s) d'appui varie entre la partie centrale et le cadre périphérique, pour par exemple diminuer du centre vers le cadre périphérique.According to another characteristic, the width of the wall (s) support varies between the central part and the peripheral frame, for par example decrease from the center to the peripheral frame.

Ajoutons que l'épaisseur de la (des) portion(s) de paroi avant et/ou arrière de la (des) paroi(s) d'appui et/ou la hauteur peut varier.Add that the thickness of the portion (s) of front wall and / or rear of the support wall (s) and / or the height may vary.

Notons aussi que les bordures de la portion de paroi avant et de la portion de paroi arrière peuvent être dans un même plan horizontal, ou dans des plans différents.Note also that the borders of the front wall portion and the rear wall portion can be in the same horizontal plane, or in different planes.

D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other characteristics and advantages of the invention will emerge of the description which will follow with regard to the appended drawings which are not given only by way of nonlimiting examples.

    • Selon un mode de réalisation préféré, la raquette désignée sous la référence générale (1) se présente sous la forme d'une plaque ajourée de plan de symétrie général (P), fixée sous la chaussure et qui se compose d'un cadre périphérique (2), constitué par au moins une paroi périphérique 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.According to a preferred embodiment, the racket designated under the general reference (1) is in the form of an openwork plate of general plane of symmetry (P), fixed under the shoe and which consists a peripheral frame (2), consisting of at least one wall peripheral delimiting an interior zone or sieve (4), comprising a set of internal walls supporting the fixing (5) intended to retain the user's shoe (6).

    Ledit cadre périphérique a une forme générale allongée se prolongeant éventuellement à l'arrière par une queue (7) de largeur réduite, tandis que l'avant peut être avantageusement relevé et de forme sensiblement pointue pour constituer la spatule avant (8). Cependant, la forme générale de ladite raquette pourrait être différente, comme, par exemple, avec un avant arrondi, ou n'avoir pas de queue, par exemple, sans pour autant sortir du cadre de l'invention. Said peripheral frame has a generally elongated shape possibly extending at the rear by a wide tail (7) reduced, while the front can be advantageously raised and shaped substantially pointed to form the front spatula (8). However, the general shape of said racket could be different, like, by example, with a rounded front, or having no tail, for example, without departing from the scope of the invention.

    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 du tamis. Notons que la fixation (5) destinée à retenir la chaussure 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'). 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 de retenue avant (10) destinés à retenir l'extrémité avant (11) de la chaussure et des moyens de retenue arrière (12) destinés à retenir l'extrémité arrière (13) de ladite chaussure .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 sieve. Note that the fixing (5) intended for retain the shoe is, according to the illustration given by way of example, articulated with respect to the sieve (4) of the racket itself, according to a transverse axis (XX '). Advantageously, said attachment carrying the general reference (5) consists of an articulated plate (9) comprising shoe retaining means, namely front retaining means (10) for retaining the front end (11) of the shoe and rear retaining means (12) for retaining the rear end (13) of said shoe.

    Le tamis (4) est constitué, du moins en partie, par une succession de parois d'appui (40) s'étendant transversalement, pour bien entendu servir de surface d'appui sur la neige mais aussi relier la partie centrale (14) supportant la fixation (5) au cadre périphérique (2).The screen (4) consists, at least in part, of a succession support walls (40) extending transversely, of course serve as a support surface on the snow but also connect the central part (14) supporting the attachment (5) to the peripheral frame (2).

    Selon le mode préféré de l'invention, l'ensemble des parois d'appui (40) relie la partie centrale (14) au cadre (2) ; cependant, certaines d'entre elles pourraient ne s'étendre transversalement que sur une longueur réduite et ne pas être reliées audit cadre.According to the preferred embodiment of the invention, all of the walls support (40) connects the central part (14) to the frame (2); however, some of them may only extend transversely over a reduced length and not be connected to said frame.

    Les parois d'appui transversales (40) sont avantageusement constituées chacune par un profil formant un caisson ouvert vers le bas, ledit profil ayant un axe général transversal (YY') et étant formé par une succession de parois comprenant au moins une portion de paroi avant (40a) s'étendant vers l'avant (AV) et vers le bas (BA) et une portion de paroi arrière (40b) s'étendant vers l'arrière et vers le bas, les deux portions de paroi (40a) et (40b) étant convergentes vers le haut. Cependant, selon des variantes possibles de l'invention, seules quelques parois (40) pourraient posséder cette forme en caisson.The transverse support walls (40) are advantageously each consisting of a profile forming a box open at the bottom, said profile having a general transverse axis (YY ') and being formed by a succession of walls comprising at least a portion of front wall (40a) extending forward (AV) and downward (BA) and a portion of rear wall (40b) extending rearward and downward, both wall portions (40a) and (40b) being converging upwards. However, according to possible variants of the invention, only a few walls (40) could have this box shape.

    Les caissons sont avantageusement de forme bombée vers le haut grâce à la forme arrondie de la section transversale des portions de parois avant (40a) et des portions de parois arrière (40b), tel qu'illustré figure 4. The boxes are advantageously curved upwards thanks to the rounded shape of the cross section of the portions of front walls (40a) and rear wall portions (40b), as shown figure 4.

    Selon des variantes possibles de l'invention, la forme de la section transversale desdites parois d'appui (40) peut être différente, sans pour autant sortir du champ de protection de ladite demande. On entendra par section transversale une coupe parallèle au plan P, c'est-à-dire transversale par rapport à l'axe YY' de chacun des profils. Ainsi la section peut, par exemple, être en forme de V ouvert vers le bas (BA), la paroi (40) étant alors formée par deux portions avant (40a) et arrière (40b) sensiblement planes, présentant un angle entre elles, ou former un U, lui aussi ouvert vers le bas (BA), grâce à une portion centrale (40c) plane et horizontale bordée latéralement d'une portion avant (40a) et arrière (40b) planes et obliques, comme illustré figures 6a et 6b.According to possible variants of the invention, the shape of the cross section of said bearing walls (40) can be different, without however, go beyond the scope of protection of said request. We will mean by cross section a section parallel to the plane P, that is to say transverse to the axis YY 'of each of the profiles. So the section can, for example, be V-shaped open downwards (BA), the wall (40) then being formed by two front (40a) and rear portions (40b) substantially planar, having an angle between them, or forming a U, also open downwards (BA), thanks to a central portion (40c) flat and horizontal laterally bordered by a front portion (40a) and rear (40b) flat and oblique, as illustrated in FIGS. 6a and 6b.

    De plus, lesdites parois d'appui (40) sont délimitées par une surface externe supérieure (41a) et une surface externe inférieure (41b) formant leur enveloppe externe, lesdites surfaces pouvant avoir un profil différent en coupe transversale, la surface inférieure (41b) pouvant former un profil en U renversé, et la surface supérieure (41a) un profil arrondi, tel qu'illustré figure 6c.In addition, said support walls (40) are delimited by a upper external surface (41a) and a lower external surface (41b) forming their outer envelope, said surfaces possibly having a profile different in cross section, the lower surface (41b) being able to form an inverted U profile, and the upper surface (41a) a rounded profile, as illustrated in Figure 6c.

    Selon le mode de réalisation préféré de l'invention, les parois d'appui (40) possèdent une section transversale de forme bombée vers le haut et leurs surfaces externes supérieures (41a) et inférieures (41b) sont sensiblement parallèles entre elles de manière à maintenir une épaisseur constante dans la section transversale, comme le montre la figure 4.According to the preferred embodiment of the invention, the walls support (40) have a cross section of curved shape towards the high and their upper (41a) and lower (41b) external surfaces are substantially parallel to each other so as to maintain a thickness constant in cross section, as shown in Figure 4.

    Selon une variante possible, ladite épaisseur peut être variable par partie ou sur l'ensemble de la section transversale, les portions de paroi avant (40a) pouvant être plus épaisses que les portions de paroi arrière (40b), comme cela est illustré à la figure 4a ou l'inverse, tel qu'illustré à la figure 4b où la portion avant (40a) est moins épaisse que la portion arrière (40b).According to a possible variant, said thickness can be variable by part or over the entire cross section, the wall portions front (40a) which can be thicker than the rear wall portions (40b), as shown in Figure 4a or vice versa, as shown in Figure 4b where the front portion (40a) is thinner than the portion rear (40b).

    La portion centrale (40c) reliant la portion avant (40a) et la portion arrière (40b) peut être plus épaisse que lesdites portions avant (40a) et arrière (40b), comme illustré figures 4c et 6c, par exemple.The central portion (40c) connecting the front portion (40a) and the rear portion (40b) may be thicker than said front portions (40a) and rear (40b), as illustrated in Figures 4c and 6c, for example.

    Notons aussi que l'épaisseur des parois peut être constante longitudinalement par rapport au profil le long de l'axe transversal (YY') comme cela est illustré figure 5 mais peut aussi varier comme, par exemple, pour être plus épaisses au voisinage du plan P et s'amincir vers le cadre périphérique (2), tel qu'illustré à la figure 5a, ou inversement tel que représenté à la figure 5b où l'épaisseur au voisinage du plan P est moins importante pour augmenter vers le cadre (2).Note also that the thickness of the walls can be constant longitudinally with respect to the profile along the transverse axis (YY ') as illustrated in figure 5 but can also vary as, for example example, to be thicker in the vicinity of the plane P and to become thinner towards the peripheral frame (2), as illustrated in Figure 5a, or vice versa as as shown in Figure 5b where the thickness in the vicinity of the plane P is less important to increase towards the frame (2).

    La figure 7 est une vue en coupe selon (CC) faite au niveau de l'axe transversal (YY'). On constate que la hauteur (h) du profilé est constante, c'est-à-dire que la hauteur (h) est la même sur toute la longueur du profilé. Bien entendu, il pourrait en être autrement et la hauteur pourrait être prévue variable et, par exemple, diminuer de la partie centrale (14) vers le cadre périphérique (2), tel qu'illustré à la figure 7a, ou inversement, augmenter de la partie centrale (14) vers le cadre périphérique (2) tel que représenté à la figure 7b.Figure 7 is a sectional view along (CC) made at the transverse axis (YY '). It can be seen that the height (h) of the profile is constant, i.e. the height (h) is the same over the entire length of the profile. Of course, it could be otherwise and the height could be expected to be variable and, for example, decrease by the part central (14) towards the peripheral frame (2), as illustrated in FIG. 7a, or vice versa, increase from the central part (14) towards the frame device (2) as shown in Figure 7b.

    Selon le mode de réalisation préféré, la largeur (1) du profil constituant les parois d'appui (40) diminue du centre vers le cadre périphérique, tel qu'illustré sur les figures 1 et 3. Cependant, il peut en être autrement, la largeur pouvant ainsi augmenter du centre vers le cadre périphérique tel que représenté à la figure 8 ou être constante comme cela est représenté à la figure 8a ou encore avoir une configuration mixte, comme illustré à la figure 8b.According to the preferred embodiment, the width (1) of the profile constituting the support walls (40) decreases from the center towards the frame device, as shown in Figures 1 and 3. However, it may be otherwise the width may increase from the center to the frame device as shown in Figure 8 or be constant as this is shown in Figure 8a or have a mixed configuration, as shown in Figure 8b.

    La forme desdites parois d'appui (40) peut comporter, comme illustré figure 3, un axe de symétrie sensiblement transversal (YY'), afin que les parois avant (40a) et arrière (40b) soient symétriques par rapport à cet axe, ou être totalement dissymétrique, comme dans le mode de réalisation illustré figure 9.The shape of said support walls (40) may include, as illustrated in FIG. 3, a substantially transverse axis of symmetry (YY '), so the front (40a) and rear (40b) walls are symmetrical with respect to to this axis, or be totally asymmetrical, as in the mode of realization illustrated in figure 9.

    De plus, les portions de paroi avant (40a) et arrière (40b) ont leurs bordures inférieures respectives (42a, 42b) situées dans le même plan horizontal, tel qu'illustré figures 4, 4a, 4b, 4c, 6a, 6b et 6c. Mais il pourrait en être autrement, comme cela est représenté aux figures 10a et 10b.In addition, the front (40a) and rear (40b) wall portions have their respective lower borders (42a, 42b) located in the same horizontal plane, as illustrated in FIGS. 4, 4a, 4b, 4c, 6a, 6b and 6c. But he could be otherwise, as shown in Figures 10a and 10b.

    Ainsi, la bordure inférieure (42a) de la portion de paroi avant (40a) pourrait être contenue dans un plan horizontal (H) de niveau inférieur à celui contenant la bordure inférieure (42b) de la portion de paroi arrière (40b), tel que représenté à la figure 10a ou inversement, la bordure inférieure (42b) de la portion de paroi arrière (40b) pourrait être à un niveau inférieur à celui de la bordure inférieure (42a) de la paroi avant (40a), comme illustré figure 10b. De plus, deux parois d'appui (40) différentes peuvent avoir les bordures inférieures de leur portion de paroi avant (40a) et/ou arrière (40b) contenues dans deux plans horizontaux différents.Thus, the lower edge (42a) of the front wall portion (40a) could be contained in a horizontal plane (H) of level lower than that containing the lower border (42b) of the portion of rear wall (40b), as shown in FIG. 10a or vice versa, the lower edge (42b) of the rear wall portion (40b) could be at a level lower than that of the lower border (42a) of the wall front (40a), as illustrated in FIG. 10b. In addition, two support walls (40) different may have the bottom edges of their wall portion front (40a) and / or rear (40b) contained in two horizontal planes different.

    Selon le mode de réalisation préféré, les bordures inférieures (42a, 42b) constituant les extrémités des portions avant et arrière (40a, 40b), autrement dit par l'intersection entre les surfaces externes supérieure et inférieure (41a, 41b) des parois (40), sont de forme arrondie. Il va de soi que lesdites bordures latérales pourraient présenter une arête formée par un angle aigu entre les surfaces externes (41a, 41b), sans pour autant sortir du champ de protection de l'invention, tel qu'illustré figure 11. De plus, selon une variante possible, cette bordure latérale en arête peut présenter un profil crénelé ou posséder de petites dents, permettant une progression plus aisée sur une pente en neige dure.According to the preferred embodiment, the lower borders (42a, 42b) constituting the ends of the front and rear portions (40a, 40b), in other words by the intersection between the external surfaces upper and lower (41a, 41b) of the walls (40), are shaped rounded. It goes without saying that said lateral borders could have an edge formed by an acute angle between the external surfaces (41a, 41b), without departing from the scope of the invention, such as illustrated in Figure 11. In addition, according to a possible variant, this border lateral edge may have a crenellated profile or have small teeth, allowing easier progression on a slope in hard snow.

    Il est à noter, comme cela apparaít plus clairement aux figures 7, 7a et 7b, que le cadre périphérique (2) est avantageusement constitué par un profilé ouvert vers le bas, formé par une paroi (200) courbe comme par exemple sensiblement cylindrique, ladite paroi n'étant pas refermée sur elle-même pour former un caisson ouvert vers le bas. La figure 12 est une variante d'exécution du cadre périphérique selon laquelle le rebord inférieur (201) de la portion de paroi externe (202) est plus bas que le rebord inférieur (203) de la portion de la paroi interne (204).It should be noted, as appears more clearly in Figures 7, 7a and 7b, that the peripheral frame (2) is advantageously constituted by a downwardly open profile formed by a wall (200) curved as for example substantially cylindrical, said wall not being closed on itself to form a box open at the bottom. Figure 12 is an alternative embodiment of the peripheral frame according to which the rim lower (201) of the outer wall portion (202) is lower than the lower edge (203) of the portion of the internal wall (204).
