Description

La présente invention concerne une raquette à neige et plus particulièrement le dispositif de retenue de la chaussure sur celle-ci.The present invention relates to a snowshoe and more particularly the device for retaining the boot thereon.

Les raquettes à neige sont des engins connus depuis de très nombreuses années car utilisées depuis plusieurs siècles par les populations Scandinaves pour se déplacer sur la neige. Jusqu'à nos jours, les raquettes à neige étaient utilisées à des fins utilitaires ou militaires, pour permettre aux populations et aux troupes alpines de se déplacer sur la neige pour leurs déplacements nécessités par la vie quotidienne. Actuellement, les raquettes à neige sont plutôt utilisées par des promeneurs ou des sportifs qui font des randonnées et des promenades, voire même des compétitions.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 walkers or sportsmen who go for hikes and walks, or even competitions.

Il existe déjà différents types de dispositifs pour retenir la chaussure sur la raquette. On en connaît plus particulièrement deux types, celui dit à plaque et celui dit à chausson caoutchouc. Généralement, les dispositifs du type à plaque sont plus souvent utilisés par les sportifs soucieux de performances car la retenue du pied est assurée avec plus de rigidité. Les dispositifs du type à chausson caoutchouc sont constitués par un emboîtement avant réalisé par une enveloppe en caoutchouc dans laquelle est retenue l'extrémité avant de la chaussure. Mais l'enceinte intérieure de l'enveloppe destinée à recevoir ladite extrémité avant est limitée latéralement par une paroi courbe dont la courbure est sensiblement identique à celle de l'avant de la chaussure. Il en résulte une possibilité de rotation de la chaussure autour d'un point situé sous l'avant du pied ce qui provoque une possibilité de déplacement latéral du talon. La retenue de la chaussure n'est donc pas bien assurée. Mais si ce dernier type de retenue est plutôt préféré des promeneurs pas trop exigeants plus que des sportifs soucieux des performances, il n'en demeure pas moins que lesdits promeneurs désirent aussi avoir une bonne tenue de leur chaussure.There are already different types of devices for retaining the shoe on the racket. We know more particularly two types, that said plate and that said rubber liner. Generally, plate-type devices are more often used by athletes concerned with performance because the retention of the foot is ensured with more rigidity. The rubber liner type devices consist of a front socket produced by a rubber casing in which the front end of the shoe is retained. However, the inner enclosure of the envelope intended to receive said front end is laterally limited by a curved wall whose curvature is substantially identical to that of the front of the shoe. This results in a possibility of rotation of the shoe around a point located under the forefoot which causes a possibility of lateral displacement of the heel. The retention of the shoe is therefore not well ensured. But if the latter type of restraint is rather preferred by strollers who are not too demanding more than sportsmen concerned with performance, the fact remains that said strollers also want to have good behavior of their shoes.

La raquette à neige selon l'invention solutionne les problèmre de retenue de la chaussure et est du type comprenant un organe de retenue avant dans lequel est retenue l'extrémité avant de ladite chaussure qui y est sollicitée par au moins un organe de traction vers l'avant caractérisée en ce que le dispositif de retenue avant est une enveloppe élastique constituée par un ensemble de parois en matériau souple formant une cavité de retenue au moins ouverte vers l'arrière, et est caractérisée en ce que la cavité de retenue comprend deux parois latérales de retenue convergentes vers l'avant et dont la convergence et leur distance l'une de l'autre est telle que l'extrémité avant de la chaussure est maintenue latéralement par ces parois en deux points latéraux distants l'un de l'autre d'une distance a plus importante possible.The snowshoe according to the invention solves the problem of retaining the boot and is of the type comprising a front retaining member in which the front end of the said boot is retained which is stressed therein by at least one traction member towards the characterized in that the front retaining device is an elastic envelope constituted by a set of walls of flexible material forming a retaining cavity at least open towards the rear, and is characterized in that the retaining cavity comprises two walls retaining lateral converging forward and whose convergence and their distance from each other is such that the front end of the shoe is held laterally by these walls at two lateral points distant from each other from a greater distance possible.

Selon une disposition préférée, la distance entre les deux points de retenue latérale de la chaussure est comprise entre la moitié de la largeur de la chaussure et la largeur de celle-ci, afin que l'extrémité de la chaussure soit retenue par ses zones latérales en dehors de la zone d'extrémité avant centrale.According to a preferred arrangement, the distance between the two lateral retention points of the shoe is between half the width of the shoe and the width of the latter, so that the end of the shoe is retained by its lateral zones outside the central front end area.

Selon une autre disposition avantageuse du dispositif, l'enveloppe élastique comprend un trou frontal. Mais elle peut comprendre une paroi avant plus éloignée ou en matériau plus souple ou d'une épaisseur moindre.According to another advantageous arrangement of the device, the elastic envelope comprises a front hole. However, it may include a more distant front wall or made of a more flexible material or of a reduced thickness.

Selon une caractéristique complémentaire, l'organe de traction est constitué par une boucle élastique dont les sangles de traction latérales sont des prolongements des parois latérales respectives.According to an additional characteristic, the traction member consists of an elastic loop whose lateral traction straps are extensions of the respective side walls.

Dans une variante de réalisation, la paroi supérieure de l'enveloppe est constituée par le recouvrement de deux languettes qui sont les prolongements respectifs des parois latérales correspondantes et qui sont solidaires l'une avec l'autre par des moyens de liaison.In an alternative embodiment, the upper wall of the envelope is constituted by the covering of two tongues which are the respective extensions of the corresponding side walls and which are integral with one another by connecting means.

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 from the description which follows with reference to the appended drawings which are given only by way of nonlimiting examples.

La raquette destinée à être équipée du dispositif selon la présente invention peut, bien entendu, être de tout type et, par exemple, comme cela est représenté aux figures 1 et 2.The racket intended to be equipped with the device according to the present invention can, of course, be of any type and, for example, as shown in FIGS. 1 and 2.

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), constitué d'une paroi périphérique (3) délimitant une zone intérieure (4), comprenant un ensemble de parois internes supportant le dispositif de retenue appelé plus communément fixation (5), destiné à retenir la chaussure (6) de l'utilisateur. Ledit cadre principal a, par exemple, une forme générale allongée se prolongeant à l'arrière par une queue (7) de largeur réduite, tandis que l'avant est relevé et de forme sensiblement pointue pour constituer la spatule avant (8). Bien entendu la raquette peut avoir tout autre forme sans pour autant sortir du cadre de l'invention.The racket designated by 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), consisting of a wall peripheral (3) delimiting an interior zone (4), comprising a set of internal walls supporting the retaining device more commonly called attachment (5), intended to retain the shoe (6) of the user. Said main frame has, for example, a generally elongated shape extending at the rear by a tail (7) of reduced width, while the front is raised and of substantially pointed shape to constitute the front spatula (8). Of course the racket can have any other shape without departing from the scope of the invention.

La chaussure (6) de l'utilisateur est retenue à la raquette proprement dite par le dispositif de retenue selon l'invention portant la référence générale (5), et qui est constitué principalement par un organe de retenue avant (9) dans lequel est retenue l'extrémité avant (10) de la chaussure (6). Par ailleurs, ladite chaussure est sollicitée vers l'avant (AV) dans l'organe de retenue avant (9) par un organe de traction vers l'avant (11).The user's shoe (6) is retained on the racket proper by the retaining device according to the invention bearing the general reference (5), and which consists mainly of a front retaining member (9) in which is retains the front end (10) of the shoe (6). Furthermore, said shoe is urged forward (AV) in the front retaining member (9) by a forward pulling member (11).

Selon un des modes d'exécution de l'invention, le dispositif de retenue (5) est un ensemble monobloc de parois, réalisé en matériau souple tel qu'en caoutchouc ou en élastomère. Ainsi, ledit dispositif comprend l'organe de retenue avant (9) qui est prolongé latéralement et vers l'arrière, par deux sangles de traction (12a, 12b) se rejoignant à l'arrière pour former une boucle monobloc de retenue (13) pour la chaussure.According to one of the embodiments of the invention, the retaining device (5) is a one-piece assembly of walls, made of flexible material such as rubber or elastomer. Thus, said device comprises the front retaining member (9) which is extended laterally and rearward, by two traction straps (12a, 12b) joining at the rear to form a one-piece retaining loop (13) for the shoe.

Ladite boucle (13) étant telle que les sangles de traction (12a, 12b) sont disposées latéralement à la chaussure pour passer derrière le talon (14) de cette dernière. Notons qu'en position de repos rétractée, tel qu'illustré aux figures 4, 5, 6 et 7, la boucle a une longueur rétractée (L1) tandis que dans la position de retenue tel qu'illustré aux figures 4, 5 et 8, sa longueur étirée (L2) est supérieure à sa longueur rétractée (L1). C'est l'élasticité du matériau constituant la boucle qui rend possible cette extension et permet à la boucle d'appliquer sur le talon de la chaussure un effort F dirigé vers l'avant, ce qui a pour effet de pousser la chaussure vers l'avant et solliciter son extrémité avant (10) dans l'organe avant de retenue (9).Said loop (13) being such that the traction straps (12a, 12b) are arranged laterally to the shoe to pass behind the heel (14) of the latter. Note that in the retracted rest position, as illustrated in Figures 4, 5, 6 and 7, the loop has a retracted length (L1) while in the retaining position as illustrated in Figures 4, 5 and 8 , its stretched length (L2) is greater than its retracted length (L1). It is the elasticity of the material constituting the buckle that makes this extension possible and allows the buckle to apply a force F directed towards the heel of the shoe, which has the effect of pushing the shoe towards the 'before and urge its front end (10) in the front retaining member (9).

L'organe avant de retenue (9) est formé par un ensemble de parois en matériau souple élastique et déformable (15a, 15b, 15c, 15d). A savoir, une paroi inférieure (15a), deux parois latérales (15b, 15c) et une paroi supérieure (15d), l'ensemble de ces parois constituant ainsi une enveloppe élastique (16) formant une cavité (17) au moins ouverte vers l'arrière (AR) dans laquelle est engagée l'extrémité avant (10) de la chaussure.The front retaining member (9) is formed by a set of walls made of flexible elastic and deformable material (15a, 15b, 15c, 15d). Namely, a lower wall (15a), two side walls (15b, 15c) and an upper wall (15d), the assembly of these walls thus constituting an elastic envelope (16) forming a cavity (17) at least open towards the rear (AR) in which is engaged the front end (10) of the shoe.

Selon l'invention, les deux parois latérales (15b, 15c) sont convergentes vers l'avant en un point O et les dimensions latérales de la cavité (17) sont telles que l'extrémité avant (10) de la chaussure est maintenue latéralement en deux points latéraux (A, B) distants d'une distance (d) la plus importante possible. La distance (d) étant, par exemple, comprise entre la moitié de la largeur (l : 2) de la chaussure et la largeur de celle-ci (l).According to the invention, the two side walls (15b, 15c) converge forward at a point O and the lateral dimensions of the cavity (17) are such that the front end (10) of the shoe is held laterally at two lateral points (A, B) distant by the greatest possible distance (d). The distance (d) being, for example, between half the width (l: 2) of the shoe and the width of the latter (l).

Notons que les parois latérales (15b, 15c) sont telles que l'avant de la chaussure est retenu en priorité, voire même uniquement par ses zones latérales (18a, 18b) mais pas par sa zone d'extrémité avant centrale (18c). Avec une telle disposition, la chaussure est retenue dans un plan sensiblement horizontal selon trois points de retenue (A, B, C) formant une triangulation de retenue permettant d'éviter tout pivotement latéral du point de retenue arrière C de la chaussure selon R1 ou R2 et ainsi assurer un maintien latéral précis de la chaussure sur la raquette.Note that the side walls (15b, 15c) are such that the front of the shoe is retained in priority, or even only by its lateral zones (18a, 18b) but not by its central front end zone (18c). With such an arrangement, the shoe is retained in a substantially horizontal plane along three retention points (A, B, C) forming a retention triangulation making it possible to avoid any lateral pivoting of the rear retention point C of the shoe according to R1 or R2 and thus ensure precise lateral support of the shoe on the racket.

Pour que le maintien de la partie avant de la chaussure se fasse comme cela est décrit précédemment, l'enveloppe élastique avant (16) comprend avantageusement un trou frontal (19) de façon à ce que la zone d'extrémité avant centrale (18c) de la chaussure ne puisse pas se trouver en appui à l'avant de l'enveloppe et que le maintien de l'avant de la chaussure se fasse bien en deux points latéraux A, B, comme selon l'invention.In order for the front part of the shoe to be held as described above, the front elastic casing (16) advantageously includes a front hole (19) so that the central front end zone (18c) of the shoe can not be in support at the front of the envelope and that the maintenance of the front of the shoe is done at two lateral points A, B, as according to the invention.

Bien entendu, la boucle peut avoir une longueur réglable, comme cela est illustré à la figure 10. Dans une telle variante, la sangle constituant la boucle est en deux parties se rejoignant en comprenant un système de réglage (20) qui peut être de tout type et notamment comme celui représenté à titre d'exemple. Notons que la boucle de retenue arrière (13) est prévue en matériau élastique, mais il pourrait en être autrement. Ainsi, la ou les sangle(s) la constituant pourrai(en)t être en matériau non élastique mais néanmoins souple et déformable, comprenant des moyens de réglage en longueur ou seulement une partie élastique.Of course, the buckle can have an adjustable length, as illustrated in FIG. 10. In such a variant, the strap constituting the buckle is in two parts joining together comprising an adjustment system (20) which can be of any type and in particular like that represented by way of example. Note that the rear retaining loop (13) is provided in elastic material, but it could be otherwise. Thus, the strap (s) constituting it may be made of non-elastic material but nevertheless flexible and deformable, comprising means for adjusting the length or only an elastic part.

Les figures 11 à 14 illustrent une variante d'exécution selon laquelle la dimension volumique et, notamment la largeur entre les deux parois latérales (15b, 15c), est réglable. A cet effet, la paroi supérieure (15d) est constituée par le recouvrement des deux languettes (151, 152), solidarisées de façon réglable l'une avec l'autre, par des moyens de liaison réglable (21). La première des languettes (15) est constituée par un prolongement de la première paroi latérale (15b), tandis que la deuxième des languettes (152) est constituée par un prolongement de la deuxième paroi latérale (15c). Ainsi, en position de retenue, les deux languettes se recouvrent au moins partiellement comme cela est illustré aux figures 11, 13 et 14, et grâce aux moyens de liaison réglables (21) il est possible d'obtenir un recouvrement plus ou moins important desdites languettes assurant ainsi une possibilité de modifier la largeur entre les deux parois latérales en fonction des dimensions en largeur de l'extrémité avant de la chaussure. Les figures 13 et 14 montrent deux réglages possibles de largeur "l1" et "l2".Figures 11 to 14 illustrate an alternative embodiment according to which the volume dimension and, in particular the width between the two side walls (15b, 15c), is adjustable. For this purpose, the upper wall (15d) is constituted by the covering of the two tongues (151, 152), secured in an adjustable manner with each other, by adjustable connecting means (21). The first of the tongues (15) is formed by an extension of the first side wall (15b), while the second of the tongues (152) is formed by an extension of the second side wall (15c). Thus, in the retaining position, the two tongues overlap at least partially as illustrated in FIGS. 11, 13 and 14, and thanks to the adjustable connecting means (21) it is possible to obtain a more or less significant overlap of said said tongues thus ensuring a possibility of modifying the width between the two side walls as a function of the width dimensions of the front end of the shoe. Figures 13 and 14 show two possible width settings "l1" and "l2".

Il va de soit que le maintien latéral de l'extrémité avant de la chaussure peut se faire avec une enveloppe avant qui comprend un trou frontal (19) comme cela est représenté aux figures 1 à 14 et à la figure 15, mais aussi avec une enveloppe comprenant une paroi frontale (190), comme cela est illustré aux figures 16 et 17. Toutefois, dans la réalisation de la figure 16, la paroi frontale est suffisamment éloignée de la zone d'extrémité avant centrale (18c) pour qu'il y ait un espace (e) entre ladite paroi frontale (190) et l'avant (18c) de la chaussure.It goes without saying that the lateral retention of the front end of the shoe can be done with a front casing which includes a front hole (19) as shown in Figures 1 to 14 and in Figure 15, but also with a envelope comprising a front wall (190), as illustrated in FIGS. 16 and 17. However, in the embodiment of FIG. 16, the front wall is sufficiently distant from the central front end zone (18c) so that it there is a space (e) between said front wall (190) and the front (18c) of the shoe.

La figure 17 illustre une variante d'exécution selon laquelle l'enveloppe ne comporte pas de trou frontal (19) comme précédemment, mais une paroi frontale élastique (190) d'épaisseur plus fine que l'épaisseur des parois latérales (15b, 15c) de façon à ce que la zone d'extrémité avant centrale (18c) de la chaussure puisse s'y appuyer sans pour autant que ladite paroi frontale n'exerce un effort important sur la chaussure ou du moins un effort beaucoup moins important.FIG. 17 illustrates an alternative embodiment according to which the envelope does not have a front hole (19) as before, but an elastic front wall (190) of thickness thinner than the thickness of the side walls (15b, 15c ) so that the central front end zone (18c) of the shoe can be supported therewith without said front wall exerting a significant effort on the shoe or at least a much less effort.

Les figures 18 et 19 illustrent une autre variante d'exécution selon laquelle la boucle (13) de traction comprend une pièce d'emboîtement arrière (25) en matériau rigide tel qu'en matière plastique. Ladite pièce d'emboîtement arrière (25) étant reliée à la partie arrière de la boucle élastique et comprenant deux parois latérales (25a, 25b) retenant l'extrémité arrière de la chaussure. Par ailleurs, cette dite pièce peut avantageusement comprendre une saillie de préhension (25c) s'étendant vers l'arrière (AR) permettant à l'utilisateur de tirer plus facilement sur la boucle lors du chaussage.Figures 18 and 19 illustrate another alternative embodiment according to which the traction loop (13) comprises a rear fitting part (25) made of rigid material such as plastic. Said rear fitting part (25) being connected to the rear part of the elastic loop and comprising two side walls (25a, 25b) retaining the rear end of the shoe. Furthermore, this said part may advantageously include a gripping projection (25c) extending rearward (AR) allowing the user to more easily pull on the buckle during putting on.

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.
