Definitions
- the present invention relates to a snowshoe and more particularly an improvement which improves performance and comfort.
- Snowshoes have been known for many years because they have been used for centuries by the Scandinavian populations to travel on snow. Until today, snowshoes were used for utility or military purposes, to allow the populations and the alpine troops to move on snow for their displacements necessary for the daily life. Currently, snowshoes are rather used by sportsmen who go for hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the equipment they use, and it is true that the products currently sold do not give full satisfaction, especially during progression on difficult snow.
- the present invention provides a new racket combining both good performance in hooking and support on the ground, while allowing easy progression both uphill and downhill, as well as in crossings.
- the snowshoe consists of an openwork plate formed by a peripheral frame comprising a vertical wall and a sieve supporting the binding intended to hold the shoe of the user, while the central part is extended towards the front by a front part and towards the rear by a rear part, and is characterized in that the width between the lateral edges of the frame and / or of the screen has in the central part a narrowing in width with respect to the part front and rear, so that the width "Lc" at the narrowing is less than the width "La" of the front part and the width "Le” of the rear part.
- the width between the lateral edges of the frame and / or the screen varies progressively from front to rear, decreasing from the front part and then increasing as the we get closer to the back.
- At least one of the lateral edges of the frame and / or of the screen is concave in the central part occupied by the shoe.
- the two peripheral side walls of the frame have a concave shape on both sides, while in another embodiment the two lateral edges of the screen have a concave shape on both sides.
- the central part corresponds to the area occupied by the shoe.
- the maximum narrowing in length that is to say where the frame and / or the sieve is (are) the narrower (s), is advantageously located in the occupied central part by the shoe.
- Figures 1 to 7 illustrate a first embodiment given by way of example.
- FIGS 1 to 2 are illustrations showing the racket according to the first embodiment with a binding, which binding is given by way of example.
- Figure 1 is a top view, but without the shoe.

- Figures 3 and 4 are views similar to Figures 1 and 2 but without the attachment and on another scale.
- Figure 5 is a bottom view of Figure 3.
- FIG. 6 is a view in longitudinal section along VI-VI of FIG. 5.
- Figures 7a, 7b, 7c, 7d, 7e are sectional views along A-A, B-B, C-C, D-D, E-E, showing the variations in width of the frame.
- Figures 8, 9, 10a, 10b, 10c, 10d, 10e are views similar to Figures 5, 6 and 7a, 7b, 7c, 7d, 7e.
- Figure 11 is a top view of another alternative embodiment.
- Figures 12, 13 and 14 are schematic top views of three alternative embodiments.
- FIGS 15 and 16 illustrate two other alternative embodiments.
- 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 of a main frame (2) and a sieve ( 4), comprising a set of walls supporting the binding (5) intended to retain the shoe (6) of the user.
- Said sieve (4) with its set of internal walls forms a general lower surface for bearing on the snow allowing the user not to sink too far into the snow, thanks to the relatively large bearing surface.
- the binding (5) for retaining the shoe (6) is, according to the illustration given by way of example, articulated with respect to the screen (4) of the racket itself, along a transverse axis (XX ') .
- said binding bearing the general reference (5) is constituted by an articulated plate (9) comprising retaining means for the shoe, namely front means (10) and rear means (11).
- the front end (12) of the shoe is, for example, retained by a front stirrup (13), while its rear end (14) is, thanks to a pivoting rear stirrup (15) comprising a retaining lever (16).
- the plate (9) is advantageously rigid and extends longitudinally, comprising an upper bearing surface (17) for supporting the sole of the shoe.
- the racket of the invention can be equipped with any other type of shoe fixing device such as, for example, that described in French patent application No. 94 05919 of the applicant.
- the racket (1) comprises a central part (20) extended, on the one hand, towards the front (AV) by a slightly raised front part (21) constituting the tip (7) and, on the other hand, towards the 'rear (AR) by a rear zone (22) constituting the heel (8).
- the frame (2) is constituted by a peripheral wall (3) perpendicular to the general horizontal plane (H) of the screen (4). Let us add that the central part (20) is bordered laterally on each side by the lateral border, on the one hand of the frame (2, 3), and on the other hand, of the screen (4).
- the central part (20) of the racket (1) is bordered on the left side (GA) by the left side wall (30a) of the frame (2) and by the left side edge (40a) of the screen, while right side (DR) it is bordered by the right side wall (30b) of the frame (2) and by the right side edge (40b) of the screen.
- the central part (20) is limited at the front by the front transverse plane (P1) separating it from the front part (21), while it is limited at the rear by the rear transverse plane (P2) .
- the side wall (30a, 30b) of the frame (2) and / or the side edge (40a, 40b) of the screen (4) has a concave curvature in the horizontal plane in the central part (20) of the racket, that is to say to have in this central part a reduced width compared to the width of the front and rear.
- Figures 1 to 7 show a first embodiment according to which it is the peripheral walls (3) of the frame (2) which have in the central part a concave profile to form a width narrowing (300) at the level of the occupied zone by the shoe.
- the width "L" between the two side walls (30a, 30b) decreases progressively towards the rear from the front plane (P1) to the middle (P3) corresponding to the most narrow, then gradually increase backwards to the rear plane (P2).
- the two side walls (30a, 30b) of the frame have a concave configuration curved according to an arc of circle of radius R, the center of the circle being in an area external to the racket (1).
- Figures 7a, 7b, 7c, 7d, 7e illustrate in different successive sections the progressive variation in width "L” between the two side walls (30a, 30b). It can thus be seen that in section AA, the width “La” is greater than the width "Lb” measured in section BB, and the width “Lc” in the center according to section CC is less than the widths "La” and “Lb ". Similarly, in section EE, the width "Le” is greater than the width "Ld” measured in section DD, and the width "Lc” in the center according to section CC is less than the widths "Le” and "Ld” .
- peripheral walls of the frame which serve as a hook during progression are close to the foot in the area of the foot and gradually move away from the plane (P) towards the front and towards the rear so that the support on the snow is sufficiently wide in the front and rear part of the racket.

- it is the lateral edges (40a, 40b) of the screen (4) which have in the central part a concave profile to form a width narrowing at the level of the zone occupied by the shoe.
- the width "L" between the two lateral edges (40a, 40b) decreases progressively towards the rear from the line (XX ') to the middle (22') corresponding to the narrowest area, then gradually increase backwards to the line (YY ').
- the two lateral edges (40a, 40b) of the frame have a concave configuration curved according to an arc of a circle of radius R, the center of the circle being an area external to the racket (1).
- Figures 10a, 10b, 10c, 10d, 10e illustrate in different successive sections the progressive variation in width "L” between the two lateral edges (40a, 40b).

Abstract
Description
La présente invention concerne une raquette à neige et plus particulièrement un perfectionnement qui en améliore les performances et le confort.The present invention relates to a snowshoe and more particularly an improvement 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, et notamment lors de la progression sur neige difficile.Snowshoes have been known for many years because they have been used for centuries by the Scandinavian populations to travel on snow. Until today, snowshoes were used for utility or military purposes, to allow the populations and the alpine troops to move on snow for their displacements necessary for the daily life. Currently, snowshoes are rather used by sportsmen who go for hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the equipment they use, and it is true that the products currently sold do not give full satisfaction, especially during progression on difficult 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, ainsi que dans les traversées.The present invention provides a new racket combining both good performance in hooking and support on the ground, while allowing easy progression both uphill and downhill, as well as in crossings.
Ainsi, selon l'invention, la raquette à neige est constituée par une plaque ajourée formée par un cadre périphérique comprenant une paroi verticale et un tamis supportant la fixation destinée à retenir la chaussure de l'utilisateur, tandis que la partie centrale est prolongée vers l'avant par une partie avant et vers l'arrière par une partie arrière, et est caractérisée en ce que la largeur entre les bordures latérales du cadre et/ou du tamis présente dans la partie centrale un rétrécissement en largeur par rapport à la partie avant et arrière, afin que la largeur "Lc" au niveau du rétrécissement soit inférieure à la largeur "La" de la partie avant et à la largeur "Le" de la partie arrière.Thus, according to the invention, the snowshoe consists of an openwork plate formed by a peripheral frame comprising a vertical wall and a sieve supporting the binding intended to hold the shoe of the user, while the central part is extended towards the front by a front part and towards the rear by a rear part, and is characterized in that the width between the lateral edges of the frame and / or of the screen has in the central part a narrowing in width with respect to the part front and rear, so that the width "Lc" at the narrowing is less than the width "La" of the front part and the width "Le" of the rear part.
Selon une caractéristique complémentaire, dans la partie centrale, la largeur entre les bordures latérales du cadre et/ou du tamis varie progressivement de l'avant vers l'arrière pour diminuer depuis la partie avant et ensuite augmenter au fur et à mesure que l'on se rapproche de la partie arrière.According to an additional characteristic, in the central part, the width between the lateral edges of the frame and / or the screen varies progressively from front to rear, decreasing from the front part and then increasing as the we get closer to the back.
Selon une autre caractéristique, l'une au moins des bordures latérales du cadre et/ou du tamis est concave dans la partie centrale occupée par la chaussure.According to another characteristic, at least one of the lateral edges of the frame and / or of the screen is concave in the central part occupied by the shoe.
Dans une des réalisations possible de l'invention, les deux parois latérales périphériques du cadre présentent des deux côtés une forme concave, tandis que dans une autre réalisation les deux bordures latérales du tamis présentent des deux côtés une forme concave.In one possible embodiment of the invention, the two peripheral side walls of the frame have a concave shape on both sides, while in another embodiment the two lateral edges of the screen have a concave shape on both sides.
Notons qu'avantageusement, la partie centrale correspond à la zone occupée par la chaussure.Advantageously, the central part corresponds to the area occupied by the shoe.
Selon une autre caractéristique complémentaire, le rétrécissement maximum en longueur, c'est-à-dire là où le cadre et/ou le tamis est(sont) le(s) plus étroit(s), se trouve avantageusement dans la partie centrale occupée par la chaussure.According to another additional characteristic, the maximum narrowing in length, that is to say where the frame and / or the sieve is (are) the narrower (s), is advantageously located in the occupied central part by the shoe.

La raquette désignée sous la référence générale (1) se présente sous la forme d'une plaque ajourée de plan de symétrie générale (P) fixée sous la chaussure et qui se compose d'un cadre principal (2) et d'un tamis (4), comprenant un ensemble de parois supportant la fixation (5) destinée à retenir la chaussure (6) de l'utilisateur.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 of a main frame (2) and a sieve ( 4), comprising a set of walls supporting the binding (5) intended to retain 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'). 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. 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 sieve (4) with its set of internal walls forms a general lower surface for bearing on the snow allowing the user not to sink too far into the snow, thanks to the relatively large bearing surface. Note that the binding (5) for retaining the shoe (6) is, according to the illustration given by way of example, articulated with respect to the screen (4) of the racket itself, along a transverse axis (XX ') . Advantageously, said binding bearing the general reference (5) is constituted by an articulated plate (9) comprising retaining means for the shoe, namely front means (10) and rear means (11). Thus, the front end (12) of the shoe is, for example, retained by a front stirrup (13), while its rear end (14) is, thanks to a pivoting rear stirrup (15) comprising a retaining lever (16). The plate (9) is advantageously rigid and extends longitudinally, comprising an 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 fixing device such as, for example, that described in French patent application No. 94 05919 of the applicant.
La raquette (1) comprend une partie centrale (20) prolongée, d'une part, vers l'avant (AV) par une partie avant (21) légèrement relevée constituant la spatule (7) et, d'autre part, vers l'arrière (AR) par une zone arrières (22) constituant le talon (8). Par ailleurs, le cadre (2) est constitué par une paroi périphérique (3) perpendiculaire au plan général horizontal (H) du tamis (4). Ajoutons que la partie centrale (20) est bordée latéralement de chaque côté par la bordure latérale, d'une part du cadre (2, 3), et d'autre part, du tamis (4). Ainsi, la partie centrale (20) de la raquette (1) est bordée du côté gauche (GA) par la paroi latérale gauche (30a) du cadre (2) et par la bordure latérale gauche (40a) du tamis, tandis que du côté droit (DR) elle est bordée par la paroi latérale droite (30b) du cadre (2) et par la bordure latérale droite (40b) du tamis. Notons que la partie centrale (20) est limitée à l'avant par le plan transversal avant (P1) la séparant de la partie avant (21), tandis qu'elle est limitée à l'arrière par le plan transversal arrière (P2).The racket (1) comprises a central part (20) extended, on the one hand, towards the front (AV) by a slightly raised front part (21) constituting the tip (7) and, on the other hand, towards the 'rear (AR) by a rear zone (22) constituting the heel (8). Furthermore, the frame (2) is constituted by a peripheral wall (3) perpendicular to the general horizontal plane (H) of the screen (4). Let us add that the central part (20) is bordered laterally on each side by the lateral border, on the one hand of the frame (2, 3), and on the other hand, of the screen (4). Thus, the central part (20) of the racket (1) is bordered on the left side (GA) by the left side wall (30a) of the frame (2) and by the left side edge (40a) of the screen, while right side (DR) it is bordered by the right side wall (30b) of the frame (2) and by the right side edge (40b) of the screen. Note that the central part (20) is limited at the front by the front transverse plane (P1) separating it from the front part (21), while it is limited at the rear by the rear transverse plane (P2) .
Selon l'invention, la paroi latérale (30a, 30b) du cadre (2) et/ou la bordure latérale (40a, 40b) du tamis (4) présente une courbure concave dans le plan horizontal dans la partie centrale (20) de la raquette, c'est-à-dire pour avoir dans cette partie centrale une largeur réduite par rapport à la largeur de l'avant et de l'arrière.According to the invention, the side wall (30a, 30b) of the frame (2) and / or the side edge (40a, 40b) of the screen (4) has a concave curvature in the horizontal plane in the central part (20) of the racket, that is to say to have in this central part a reduced width compared to the width of the front and rear.
Les figures 1 à 7 représentent un premier mode de réalisation selon lequel ce sont les parois périphériques (3) du cadre (2) qui présentent dans la partie centrale un profil concave pour former un rétrécissement en largeur (300) au niveau de la zone occupée par la chaussure. Dans cette réalisation, la largeur "L" entre les deux parois latérales (30a, 30b) diminue de façon progressive vers l'arrière depuis le plan avant (P1) jusqu'au milieu (P3) correspondant à la zone la plus étroite, pour ensuite augmenter progressivement vers l'arrière jusqu'au plan arrière (P2). Notons que les deux parois latérales (30a, 30b) du cadre ont une configuration concave courbe selon un arc de cercle de rayon R, le centre du cercle étant dans une zone extérieure à la raquette (1). Les figures 7a, 7b, 7c, 7d, 7e illustrent selon différentes coupes successives la variation progressive de largeur "L" entre les deux parois latérales (30a, 30b). On constate ainsi que dans la coupe A-A, la largeur "La" est supérieure à la largeur "Lb" mesurée dans la coupe B-B, et la largeur "Lc" au centre selon la coupe C-C est inférieure aux largeurs "La" et "Lb". De même, dans la coupe E-E, la largeur "Le" est supérieure à la largeur "Ld" mesurée dans la coupe D-D, et la largeur "Lc" au centre selon la coupe C-C est inférieure aux largeurs "Le" et "Ld". Avec une telle construction du cadre on constate que les parois périphériques du cadre qui servent d'accrochage lors de la progression sont près du pied dans la zone du pied et s'éloignent progressivement du plan (P) vers l'avant et vers l'arrière pour que l'appui sur la neige soit suffisamment large dans la partie avant et arrière de la raquette.Figures 1 to 7 show a first embodiment according to which it is the peripheral walls (3) of the frame (2) which have in the central part a concave profile to form a width narrowing (300) at the level of the occupied zone by the shoe. In this embodiment, the width "L" between the two side walls (30a, 30b) decreases progressively towards the rear from the front plane (P1) to the middle (P3) corresponding to the most narrow, then gradually increase backwards to the rear plane (P2). Note that the two side walls (30a, 30b) of the frame have a concave configuration curved according to an arc of circle of radius R, the center of the circle being in an area external to the racket (1). Figures 7a, 7b, 7c, 7d, 7e illustrate in different successive sections the progressive variation in width "L" between the two side walls (30a, 30b). It can thus be seen that in section AA, the width "La" is greater than the width "Lb" measured in section BB, and the width "Lc" in the center according to section CC is less than the widths "La" and "Lb ". Similarly, in section EE, the width "Le" is greater than the width "Ld" measured in section DD, and the width "Lc" in the center according to section CC is less than the widths "Le" and "Ld" . With such a construction of the frame, it can be seen that the peripheral walls of the frame which serve as a hook during progression are close to the foot in the area of the foot and gradually move away from the plane (P) towards the front and towards the rear so that the support on the snow is sufficiently wide in the front and rear part of the racket.
Il va de soi que l'on ne sortirait pas du cadre de l'invention si seul le tamis (4) était tel que sa largeur à l'avant et à l'arrière soit supérieure à sa largeur au centre, comme cela est illustré par les figures 8, 9 et 10. Ainsi, dans cette réalisation, ce sont les bordures latérales (40a, 40b) du tamis (4) qui présentent dans la partie centrale un profil concave pour former un rétrécissement en largeur au niveau de la zone occupée par la chaussure. Dans cette réalisation, la largeur "L" entre les deux bordures latérales (40a, 40b) diminue de façon progressive vers l'arrière depuis la ligne (XX') jusqu'au milieu (22') correspondant à la zone la plus étroite, pour ensuite augmenter progressivement vers l'arrière jusqu'à la ligne (YY'). Notons que les deux bordures latérales (40a, 40b) du cadre ont une configuration concave courbe selon un arc de cercle de rayon R, le centre du cercle étant une zone extérieure à la raquette (1). Les figures 10a, 10b, 10c, 10d, 10e, illustrent selon différentes coupes successives la variation progressive de largeur "L" entre les deux bordures latérales (40a, 40b). On constate ainsi que dans la coupe A-A, la largeur "La" est supérieure à la largeur "Lb" mesurée dans la coupe B-B et que la largeur "Lc" au centre selon la coupe C-C est inférieure aux largeurs "La" et "Lb". De même, dans la coupe E-E, la largeur "Le" est supérieure à la largeur "Ld" mesurée dans la coupe D-D et la largeur "Lc" au centre selon la coupe C-C est inférieure aux largeurs "Le" et "Ld".It goes without saying that it would not go beyond the scope of the invention if only the screen (4) was such that its width at the front and at the rear was greater than its width at the center, as illustrated by FIGS. 8, 9 and 10. Thus, in this embodiment, it is the lateral edges (40a, 40b) of the screen (4) which have in the central part a concave profile to form a width narrowing at the level of the zone occupied by the shoe. In this embodiment, the width "L" between the two lateral edges (40a, 40b) decreases progressively towards the rear from the line (XX ') to the middle (22') corresponding to the narrowest area, then gradually increase backwards to the line (YY '). Note that the two lateral edges (40a, 40b) of the frame have a concave configuration curved according to an arc of a circle of radius R, the center of the circle being an area external to the racket (1). Figures 10a, 10b, 10c, 10d, 10e, illustrate in different successive sections the progressive variation in width "L" between the two lateral edges (40a, 40b). It can thus be seen that in section AA, the width "La" is greater than the width "Lb" measured in section BB and that the width "Lc" in the center according to section CC is less than the widths "La" and "Lb ". Similarly, in section EE, the width "Le" is greater than the width "Ld" measured in the section DD and the width "Lc" in the center according to section CC is less than the widths "Le" and "Ld".
La figure 11 est une vue de dessus représentant un autre mode de réalisation selon lequel il est associé les courbures des parois latérales (30a, 30b) du cadre de la réalisation des figures 1 à 7 et les courbures des bordures latérales (40a, 40b) du tamis.Figure 11 is a top view showing another embodiment in which it is associated the curvatures of the side walls (30a, 30b) of the frame of the embodiment of Figures 1 to 7 and the curvatures of the side edges (40a, 40b) sieve.
Il va de soi que la raquette pourrait être dissymétrique, comme cela est illustré aux figures 12, 13 et 14 qui illustrent trois autres modes d'exécution de réalisation des figures 3, 8 et 11 où seulement la bordure latérale de l'un des côtés gauche ou droit est concave.It goes without saying that the racket could be asymmetrical, as illustrated in FIGS. 12, 13 and 14 which illustrate three other embodiments of FIGS. 3, 8 and 11 where only the lateral border of one of the sides left or right is concave.
Les figures 15 et 16 illustrent de façon schématique d'autres modes d'exécution possibles. Selon la variante de la figure 15, les courbures concaves gauche et droite sont dissymétriques par rapport au plan P. Selon les variantes de la figure 16, il est illustré une autre façon de prévoir la forme concave des bordures qui sont réalisées par des segments rectilignes au lieu d'une forme courbe.Figures 15 and 16 schematically illustrate other possible embodiments. According to the variant of FIG. 15, the left and right concave curvatures are asymmetrical with respect to the plane P. According to the variants of FIG. 16, another way of providing the concave shape of the borders which are produced by rectilinear segments is illustrated. instead of a curved shape.
On notera que la partie centrale (20) de la raquette correspond avantageusement à la zone occupée par la fixation et la chaussure de l'utilisateur.Note that the central part (20) of the racket advantageously corresponds to the area occupied by the binding and the user's shoe.
Par ailleurs, ajoutons que le rétrécissement maximum en largueur, c'est-à-dire là où le cadre et/ou le tamis est(sont) le(s) plus étroit(s), se trouve avantageusement dans la partie centrale occupée par la chaussure, comme cela apparaît clairement sur les figures.In addition, let us add that the maximum narrowing in width, that is to say where the frame and / or the screen is (are) the narrower (s), is advantageously in the central part occupied by the shoe, as can be clearly seen in the figures.
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 embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
