Description

La présente invention concerne un couteau pour raquette à neige destiné à être monté sur une raquette à neige de manière amovible. Elle est aussi relative à une raquette à neige destinée à être équipée dudit couteau.The present invention relates to a knife for snowshoeing intended to be removably mounted on a snowshoe. She also relates to a snowshoe intended to be equipped with said knife.

Les raquettes à neige sont des engins connus depuis de très nombreuses années car utilisées depuis plusieurs siècles par les populations Scandinaves pour se déplacer sur la neige. Jusqu'à nos jours, les raquettes à neige étaient utilisées à des fins utilitaires ou militaires, pour permettre aux populations et aux troupes alpines de se déplacer sur la neige pour leurs déplacements nécessités par la vie quotidienne. Actuellement, les raquettes à neige sont plutôt utilisées par des sportifs qui font des randonnées et des promenades, voire même des compétitions. Mais les sportifs, bien que pratiquant pour leur plaisir, sont de plus en plus exigeants pour le matériel qu'ils utilisent, et il est vrai que les produits actuellement vendus ne donnent pas entière satisfaction.Snowshoes have been known for a long time many years because used for several centuries by Scandinavian people to move on the snow. Until our days, snowshoes were used for utility or military purposes, to allow the populations and the alpine troops to move on the snow for their daily necessities. Currently, snowshoes are used more by athletes who go on hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the material they use, and it is true that the products currently sold are not entirely satisfactory.

Ainsi, les raquettes à neige doivent combiner des critères d'accroche et de portance tout en conservant un confort maximum pour leurs utilisateurs. La combinaison de ces critères revêt d'ailleurs une importance particulière, et ce, notamment dans des conditions de pratique difficiles comme, par exemple, dans de la neige dure ou glacée ou dans des conditions de pente importante. Les raquettes actuelles ne permettent malheureusement pas d'obtenir une accroche suffisante dans de telles conditions et rendent mal aisée la progression de leurs utilisateurs. Par ailleurs, il peut être nécessaire également de diminuer l'accroche de la raquette dans certains types d'utilisation de la raquette ou de conditions de neige comme, par exemple, lors de la descente.Thus, snowshoes must combine criteria grip and lift while maintaining maximum comfort for their users. The combination of these criteria also has a particular importance, especially in conditions of difficult practice like, for example, in hard or icy snow or in steep slope conditions. Current snowshoes do unfortunately do not allow to obtain a sufficient grip in such conditions and make it difficult to progress their users. In addition, it may also be necessary to reduce the grip of the racket in certain types of racket use or snow conditions like, for example, when going downhill.

Ainsi, la présente invention se propose de résoudre les inconvénients précités grâce à des moyens simples, fiables, sûrs et peu onéreux. Elle présente donc un perfectionnement pour raquette à neige destiné à permettre l'adaptation de la raquette aux conditions de neige et de pente grâce à des moyens d'accroche, tel qu'un couteau, lesdits moyens s'adaptant avantageusement de manière amovible sous le raquette en cas de nécessité et selon le désir de l'utilisateur.Thus, the present invention proposes to solve the disadvantages mentioned above by simple, reliable, safe and inexpensive means expensive. It therefore presents an improvement for snowshoeing intended to allow the adaptation of the racket to snow conditions and slope by means of attachment, such as a knife, said means advantageously adaptably removable under the racket if necessary and as desired by the user.

Selon sa caractéristique principale, le couteau pour raquette à neige selon l'invention est caractérisé en ce qu'il comprend des moyens d'assemblage destinés à permettre son assemblage de façon amovible à la raquette.According to its main characteristic, the racket knife snow according to the invention is characterized in that it comprises means assembly intended to allow its assembly in a removable manner to racket.

Selon une caractéristique complémentaire du couteau, celui-ci est en partie caractérisé en ce que ses moyens d'assemblage sont constitués par au moins une surface d'appui supérieure destinée à venir en appui contre une surface d'appui inférieure du tamis de la raquette.According to an additional characteristic of the knife, it is partly characterized in that its assembly means consist by at least one upper bearing surface intended to come to bear against a lower bearing surface of the racket sieve.

Selon le mode de réalisation préféré du couteau pour raquette à neige selon l'invention, ses moyens d'assemblage comportent des moyens de blocage en rotation constitués par une saillie centrale destinée à s'engager dans un trou du tamis de la raquette, la forme de la saillie centrale étant complémentaire et ajustée à celle dudit trou.According to the preferred embodiment of the racket knife snow according to the invention, its assembly means include rotation blocking means constituted by a central projection intended to engage in a hole in the sieve of the racket, the shape of the central projection being complementary and adjusted to that of said hole.

Selon une caractéristique complémentaire du couteau selon l'invention, il comporte des moyens de verrouillage destinés à permettre le verrouillage en position du couteau sur la raquette à neige.According to an additional characteristic of the knife according to the invention, it comprises locking means intended to allow locking the knife in position on the snowshoe.

Selon une autre caractéristique du couteau pour raquette à neige selon l'invention, celui-ci est caractérisé en ce que les moyens de verrouillage comportent un verrou destiné à venir en appui sur la face supérieure du tamis de la raquette à neige.According to another characteristic of the snowshoe knife according to the invention, it is characterized in that the means for locking include a lock intended to come to bear on the face upper of the snowshoe sieve.

Selon un mode de réalisation du couteau, le verrou est constitué par une portion de paroi montée pivotante sur la saillie centrale.According to one embodiment of the knife, the lock consists by a wall portion pivotally mounted on the central projection.

Selon une caractéristique complémentaire du couteau, il comporte deux parois latérales munies d'un ensemble de dents, lesdites parois latérales étant disposées de part et d'autre d'un plan de symétrie i longitudinal du couteau . According to an additional characteristic of the knife, it has two side walls provided with a set of teeth, said teeth side walls being arranged on either side of a plane of symmetry i longitudinal of the knife.

Selon une variante d'exécution du couteau, les parois latérales sont parallèles au plan de symétrie longitudinal du couteau, ledit plan étant destiné à être confondu avec le plan de symétrie longitudinal de la raquette à neige lors de son assemblage.According to an alternative embodiment of the knife, the side walls are parallel to the longitudinal plane of symmetry of the knife, said plane being intended to be confused with the longitudinal plane of symmetry of the snowshoe during assembly.

Par ailleurs, l'invention concerne également une raquette à neige destinée à recevoir un couteau amovible tel que celui décrit ultérieurement, ladite raquette comportant des moyens d'assemblage complémentaires destinés à coopérer avec les moyens d'assemblage du couteau.Furthermore, the invention also relates to a snowshoe intended to receive a removable knife such as that described subsequently, said racket comprising assembly means intended to cooperate with the assembly means of the knife.

De plus selon une variante d'exécution, la raquette à neige comprend des moyens de verrouillage destinés à permettre le verrouillage en position du couteau sur la raquette.In addition, according to a variant, the snowshoe includes locking means intended to allow the locking in position of the knife on the racket.

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

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

Selon le mode de réalisation de la raquette sur laquelle est destiné à être monté le couteau, la plaque ajourée a une forme générale allongée dont l'avant est avantageusement relevé et de forme sensiblement pointue pour constituer la spatule avant (8), tandis que sa zone centrale (60) située sous la chaussure (6) de l'utilisateur et donc sous la plaque (9), dans le cas d'une fixation telle qu'illustrée aux figures 1 et 2, comprend une arête longitudinale (18) s'étendant, par exemple, depuis l'axe transversal d'articulation de la plaque (XX') jusqu'au talon (19) de la raquette. Ladite arête longitudinale (18) sert avantageusement d'appui pour la chaussure (6) ou pour la plaque (9) dans le cas d'une fixation du type à plaque articulée. Ajoutons que l'arête longitudinale (18) comprend une surface d'appui centrale horizontale (20) qui, selon l'invention, est prolongée latéralement de part et d'autre par une surface latérale longitudinale inclinée (21a, 21b), à savoir, une surface inclinée gauche (21a) et une surface inclinée droite (21b). Notons que les deux surfaces inclinées (21a, 21b) sont convergentes vers le haut, comme le montre la figure 7.According to the embodiment of the racket on which is intended to be mounted the knife, the perforated plate has a general shape elongated whose front is advantageously raised and shaped substantially pointed to form the front spatula (8), while its central area (60) located under the shoe (6) of the user and therefore under the plate (9), in the case of a fixing as illustrated in FIGS. 1 and 2, includes a longitudinal edge (18) extending, for example, from the transverse axis of articulation of the plate (XX ') to the heel (19) of the racket. Said longitudinal edge (18) advantageously serves as a support for the shoe (6) or for the plate (9) in the case of a fixing of the hinged plate type. Add that the longitudinal edge (18) includes a horizontal central support surface (20) which, according to the invention, is laterally extended on both sides by a lateral surface longitudinal inclined (21a, 21b), i.e., a left inclined surface (21a) and a straight inclined surface (21b). Note that the two surfaces inclined (21a, 21b) converge upwards, as shown in the figure 7.

Par ailleurs, la paroi centrale (20) de l'arête longitudinale (18) comprend au moins un trou allongé (180a, 180b, 180c) tel qu'illustré figures 5 et 6. Dans le mode représenté, l'arête longitudinale (18) comprend un trou avant (180a), un trou central (180b) et un trou arrière (180c). Ajoutons que l'arête longitudinale comprend deux saillies longitudinales latérales (25a, 25b) s'étendant vers le bas (BA) de part et d'autre des trous avant (180a) et central (180b). Notons que l'arête longitudinale, ses trous et ses prolongements latéraux constituent des moyens d'assemblage complémentaires destinés à coopérer avec des moyens d'assemblage du couteau, tels que ceux décrits ultérieurement. Il va de soi que la raquette à neige pourrait être de forme différente, sans pour autant sortir du champ de protection revendiqué de l'invention.Furthermore, the central wall (20) of the longitudinal edge (18) includes at least one elongated hole (180a, 180b, 180c) as shown Figures 5 and 6. In the mode shown, the longitudinal edge (18) includes a front hole (180a), a central hole (180b) and a rear hole (180c). Add that the longitudinal edge includes two projections longitudinal sideways (25a, 25b) extending downwards (BA) on both sides and on the other, the front (180a) and central (180b) holes. Note that the edge longitudinal, its holes and its lateral extensions constitute complementary assembly means intended to cooperate with knife assembly means, such as those described later. he It goes without saying that the snowshoe could be of a different shape, without however, depart from the claimed protective field of the invention.

L'invention concerne principalement des moyens d'accroche de la raquette dans la neige comme un couteau portant la référence générale (30) tel qu'illustré figures 8 et 9, et plus particulièrement les moyens d'assemblage et les moyens de verrouillage dudit couteau (30) sur la raquette (1). Le couteau (30) est destiné à être monté sur la raquette à neige (1) de manière amovible. Il est avantageusement constitué par un profilé métallique comme, par. exemple, en aluminium. Il va de soi que le couteau pourrait être réalisé dans toute autre matière suffisamment rigide et solide pour assurer sa fonction d'accroche sur la neige, sans pour autant sortir du champ de protection revendiqué de l'invention.The invention mainly relates to means for attaching snowshoeing in the snow like a knife with the general reference (30) as illustrated in FIGS. 8 and 9, and more particularly the means assembly and the locking means of said knife (30) on the racket (1). The knife (30) is intended to be mounted on the racket at snow (1) removably. It is advantageously constituted by a metal profile as per. example, aluminum. It goes without saying that the knife could be made of any other sufficiently rigid material and solid to ensure its grip function on snow, without as well go beyond the claimed protective field of the invention.

Selon le mode de réalisation préféré du couteau (30) selon l'invention, il comporte des moyens d'assemblage destinés à permettre sa mise en place sur la raquette à neige (1), il comporte également des moyens de verrouillage destinés à permettre son verrouillage en position sur celle-ci, l'assemblage et le verrouillage s'effectuant avantageusement de manière amovible.According to the preferred embodiment of the knife (30) according to the invention, it comprises assembly means intended to allow its installation on the snowshoe (1), it also includes locking means intended to allow it to be locked in position on the latter, the assembly and locking advantageously taking place removably.

Selon l'invention, les moyens d'assemblage du couteau (30) sont constitués en partie par une surface d'appui supérieure (31) destinée à s'appuyer sur une surface d'appui inférieure (32) du tamis (4). Cette surface d'appui inférieure du tamis (32) est complémentaire à la surface d'appui supérieure (31) du couteau (30) et constitue en partie les moyens d'assemblage complémentaires de la raquette à neige. Notons que la surface d'appui inférieure (32) du tamis (4) est constituée par les parois d'extrémité inférieure des surfaces inclinées (21a, 21b) et celles des saillies longitudinales (25a, 25b). La surface d'appui supérieure (31) du couteau (30) est formée par deux surfaces d'appui latérales (31a, 31b, 310a, 310b) destinées à coopérer respectivement avec les bords d'extrémités inférieures des saillies longitudinales (25a, 25b) et des surfaces inclinées (21a, 21b) du tamis, comme le montre la figure 13. Il va de soi que les profils des parois d'appui supérieures du couteau et des parois d'appui inférieures du tamis qui constituent les moyens d'assemblage respectifs de la raquette et du couteau, pourraient être différents et rester complémentaires, sans pour autant sortir du champ de protection revendiqué de l'invention.According to the invention, the means for assembling the knife (30) are partly formed by an upper bearing surface (31) intended to lean on a lower bearing surface (32) of the screen (4). This lower support surface of the screen (32) is complementary to the surface upper support (31) of the knife (30) and partly constitutes the means additional assembly of the snowshoe. Note that the lower support surface (32) of the screen (4) is formed by the walls lower end of the inclined surfaces (21a, 21b) and those of the longitudinal projections (25a, 25b). The upper bearing surface (31) of the knife (30) is formed by two lateral bearing surfaces (31a, 31b, 310a, 310b) intended to cooperate respectively with the edges lower ends of the longitudinal projections (25a, 25b) and inclined surfaces (21a, 21b) of the sieve, as shown in Figure 13. It will the profiles of the upper bearing walls of the knife and of the lower support walls of the screen which constitute the means assembly of the racket and the knife, could be different and remain complementary, without going beyond the scope of claimed protection of the invention.

D'autre part, les moyens d'assemblage du couteau et de la raquette à neige comportent également des moyens de blocage en rotation qui sont constitués par une saillie centrale (33) destinée à être engagée dans le trou avant (180a), comme le montrent les figures 10, 11 et 12, le blocage en rotation se faisant par coopération et butée des faces latérales (33a, 33b) de la saillie centrale (33) avec les parois internes (250a, 250b) des saillies latérales (25a, 25b) bordant le trou avant (180a). Notons ainsi que la forme de la saillie centrale est complémentaire et ajustée à la forme et aux dimensions du trou (180a, 180b, 180c) qui la reçoit afin de bloquer précisément tout pivotement du couteau par rapport à la raquette à neige.On the other hand, the means of assembling the knife and the snowshoeing also include locking means in rotation which are constituted by a central projection (33) intended to be engaged in the front hole (180a), as shown in Figures 10, 11 and 12, the rotation lock being done by cooperation and abutment of the faces lateral (33a, 33b) of the central projection (33) with the internal walls (250a, 250b) lateral projections (25a, 25b) bordering the front hole (180a). Note therefore that the shape of the central projection is complementary and adjusted to the shape and dimensions of the hole (180a, 180b, 180c) which receives in order to precisely block any pivoting of the knife by compared to snowshoeing.

Selon le mode de réalisation préféré, le couteau (30) comprend des moyens de verrouillage destinés à permettre sa fixation de façon amovible sur la raquette. Les moyens de verrouillage sont constitués en partie par un verrou (35) destiné à venir en appui sur la face supérieure du tamis, c'est-à-dire sur la paroi centrale (20) de l'arête longitudinale (18) de la raquette à neige et plus précisément sur les bords de son trou avant (180a). Notons aussi que la saillie centrale (33) du couteau (30) est telle que sa paroi supérieure (330) comprend un prolongement arrière (330a) s'étendant vers l'arrière destiné à être engagé dans le trou avant (180a) pour être en appui sur la surface d'appui (20) de l'arête longitudinale (18) comme le montrent les figures 11 et 12, ledit prolongement arrière (330a) permettant ainsi aux moyens de verrouillage de posséder deux zones d'appui supérieures sur le tamis de la raquette afin de maintenir la surface d'appui supérieure (31) du couteau (30) contre la surface d'appui inférieure (32) du tamis, comme le montre la figure 13.According to the preferred embodiment, the knife (30) comprises locking means intended to allow it to be fixed so removable on the racket. The locking means consist of part by a lock (35) intended to come to bear on the upper face sieve, i.e. on the central wall (20) of the longitudinal edge (18) of the snowshoe and more precisely on the edges of its hole before (180a). Note also that the central projection (33) of the knife (30) is such that its upper wall (330) includes a rear extension (330a) extending rearward to be engaged in the front hole (180a) to bear on the bearing surface (20) of the edge longitudinal (18) as shown in Figures 11 and 12, said rear extension (330a) thus allowing the locking means have two upper support zones on the racket sieve in order to maintain the upper bearing surface (31) of the knife (30) against the lower bearing surface (32) of the screen, as shown in the figure 13.

Il est important de noter que selon le mode de réalisation préféré du couteau , de la raquette et de leurs moyens d'assemblage respectifs, lesdits moyens permettent avantageusement le positionnement du couteau par engagement de celui ci par le dessous de la raquette.It is important to note that according to the preferred embodiment knife, racket and their respective assembly means, said means advantageously allow the positioning of the knife by engagement of this one by the underside of the racket.

Selon le mode de réalisation préféré, le verrou (35) est obtenu de manière connue en soi grâce à une portion de paroi montée pivotante sur la saillie centrale (33) autour d'un axe (34). Il va de soi que, selon ce mode de réalisation, le verrou (35) peut également comporter des moyens de serrage grâce à son axe (34) qui peut être fileté de manière à pouvoir coopérer avec un écrou à ailette, par exemple pour verrouiller fermement l'assemblage du couteau sur la raquette à neige et éviter tout jeu entre les deux qui pourrait gêner l'utilisateur lors de sa progression. Il va de soi que les moyens de verrouillage pourraient être obtenus par des dispositifs équivalents, sans pour autant sortir du champ de protection revendiqué de l'invention. De même le couteau (30) pourrait ne comporter que des moyens d'assemblage, les moyens de verrouillage destinés à verrouiller le couteau dans sa position pouvant être disposés directement sur la raquette à neige et être constitués par exemple par un verrou de type coulissant.According to the preferred embodiment, the lock (35) is obtained from in a manner known per se thanks to a pivotally mounted wall portion on the central projection (33) around an axis (34). It goes without saying that, according to what embodiment, the latch (35) may also include clamping means thanks to its axis (34) which can be threaded so as to ability to cooperate with wing nut, for example to lock firmly assemble the knife on the snowshoe and avoid any game between the two which could hinder the user during his progress. he it goes without saying that the locking means could be obtained by means of equivalent devices, without going outside the protective field claimed of the invention. Similarly, the knife (30) could not include only assembly means, the locking means for locking the knife in its position which can be arranged directly on the snowshoe and be constituted for example by a sliding type lock.

Selon l'invention, le couteau (30) comprend deux parois latérales (36, 37) munies d'une succession de dents (36a, 36b, 36c, 37a, 37b, 37c) comme le montrent les figures 8 et 10. Les parois latérales (36, 37) prolongent les parois d'appui (310a, 310b) et forment avec elles sensiblement un angle droit de manière à s'étendre verticalement vers le bas, comme le montre la figure 9. Elles sont disposées parallèlement de part et d'autre du plan de symétrie longitudinal (Q) du couteau (30) avantageusement de manière symétrique, ledit plan (Q) du couteau (30) étant destiné à se confondre avec le plan (P) de symétrie général longitudinal de la raquette à neige lors de l'assemblage du couteau sur celle-ci.According to the invention, the knife (30) comprises two side walls (36, 37) provided with a succession of teeth (36a, 36b, 36c, 37a, 37b, 37c) as shown in Figures 8 and 10. The side walls (36, 37) extend the support walls (310a, 310b) and form with them substantially a right angle so as to extend vertically towards the bottom, as shown in Figure 9. They are arranged parallel to on either side of the longitudinal plane of symmetry (Q) of the knife (30) advantageously symmetrically, said plane (Q) of the knife (30) being intended to merge with the plane (P) of general symmetry longitudinal of the snowshoe when assembling the knife on this one.

Selon le mode de réalisation préféré du couteau selon l'invention, les dents (36a, 36b, 36c, 37a, 37b, 37c) des parois latérales sont de même dimension, leurs extrémités étant situées dans un même plan horizontal (H1), comme le montre la figure 8. Cependant, il va de soi que la taille des dents pourrait être différente d'une paroi à l'autre ou au sein d'une même paroi. Ainsi, selon la variante d'exécution illustrée figure 17, la taille des dents augmente avantageusement d'avant (AV) en arrière (AR). Notons que l'extrémité des dents (36a, 36b, 36c, 36d, 37a, 37b, 37c, 37d) peut ainsi être disposée soit dans un même plan, soit dans plusieurs plans différents, lesdits plans étant situés sous le plan horizontal (H2) défini par le bord inférieur (7) du cadre (2).According to the preferred embodiment of the knife according to the invention, the teeth (36a, 36b, 36c, 37a, 37b, 37c) of the side walls are the same dimension, their ends being located in the same horizontal plane (H1), as shown in Figure 8. However, it goes without saying that the size teeth could be different from one wall to another or within a same wall. Thus, according to the alternative embodiment illustrated in FIG. 17, the teeth size advantageously increases from front (AV) to back (AR). Note that the end of the teeth (36a, 36b, 36c, 36d, 37a, 37b, 37c, 37d) can thus be arranged either in the same plane or in several planes different, said planes being located under the horizontal plane (H2) defined by the lower edge (7) of the frame (2).

Selon le mode de réalisation préféré du couteau selon l'invention, sa mise en place et son assemblage sur la raquette à neige s'effectuent, comme le montrent les figures 10 à 12 en engageant la saillie centrale (33) dans le trou avant (180a) de manière à positionner le prolongement arrière (330a) en appui sur la portion de paroi de l'arête (18) qui sépare le trou avant (180a) du trou central (180b). Lorsque l'ensemble des surfaces d'appui respectives (31, 32) sont positionnées, il suffit de verrouiller le couteau à l'aide de son verrou pivotant (35).According to the preferred embodiment of the knife according to the invention, it is put in place and assembled on the snowshoe, as shown in figures 10 to 12 by engaging the central projection (33) in the front hole (180a) so as to position the extension rear (330a) resting on the wall portion of the edge (18) which separates the front hole (180a) of the central hole (180b). When all of respective bearing surfaces (31, 32) are positioned, it suffices to lock the knife using its swivel lock (35).

Notons que les moyens d'assemblage et de verrouillage du couteau et de la raquette à neige pourraient avoir une configuration différente, sans pour autant sortir du champ de protection de l'invention. Ainsi, le couteau pourrait, par exemple, être positionné en s'engageant par le dessus du tamis à cheval sur l'arête longitudinale, par exemple, le verrou pivotant verrouillant alors le couteau par le dessous de la raquette à neige.Note that the assembly and locking means of the knife and snowshoe could have a configuration different, without departing from the scope of protection of the invention. Thus, the knife could, for example, be positioned while engaging from above the sieve straddling the longitudinal edge, for example, the swivel lock then locks the knife from below the racket snow.

Par ailleurs, selon un mode d'exécution non représenté, le couteau pourrait être assemblé à la raquette à neige non plus sur son tamis mais directement sous la plaque articulée de la fixation, les moyens d'assemblage et de verrouillage du couteau à la plaque pouvant être similaires à ceux décrits précédemment. Furthermore, according to an embodiment not shown, the knife could be assembled to the snowshoe either on its sieve but directly under the articulated plate of the fixing, the means assembly and locking of the knife to the plate which can be similar to those described above.

Selon une autre variante d'exécution, les parois latérales (36, 37) sont inclinées par rapport au plan de symétrie (Q) du couteau de manière à converger vers le haut (HA), comme le montre la figure 16. Selon ce mode de réalisation, la face externe des parties supérieures desdites parois (36, 37) peut constituer une paroi d'appui destinée à coopérer avec la face inférieure des surfaces inclinées (21a, 21b) du tamis (4) qui constitue ainsi un renfort latéral pour lesdites parois.According to another alternative embodiment, the side walls (36, 37) are inclined with respect to the plane of symmetry (Q) of the knife so as to converge upwards (HA), as shown in Figure 16. According to this embodiment, the external face of the upper parts said walls (36, 37) can constitute a support wall intended to cooperate with the underside of the inclined surfaces (21a, 21b) of the screen (4) which thus constitutes a lateral reinforcement for said walls.

Selon un autre mode de réalisation du couteau illustré figure 18, les parois latérales (36, 37) ne sont plus disposées parallèlement au plan (Q), mais sont disposées de manière à converger vers l'avant (AV). Elles forment ainsi dans un plan longitudinal avec le plan (Q) un angle (σ) ouvert vers l'arrière (AR) compris entre 0 et 60°. Il va de soi que l'inclinaison des parois latérales, le nombre de dents qu'elles portent ainsi que leur configuration pourraient être différents, sans pour autant sortir du champ de protection revendiqué de l'invention.According to another embodiment of the knife illustrated in FIG. 18, the side walls (36, 37) are no longer arranged parallel to the plane (Q), but are arranged to converge forward (AV). They thus form in an longitudinal plane with the plane (Q) an angle (σ) open to the rear (AR) between 0 and 60 °. It is obvious that the inclination of the side walls, the number of teeth they carry as well as their configuration could be different, without go outside the claimed protective field of the invention.

Selon un mode de réalisation non représenté, le couteau peut comporter une paroi d'accroche transversale qui relie ses parois latérales, ladite paroi transversale pouvant également comporter un ensemble de dents transversales ou longitudinales.According to an embodiment not shown, the knife can have a transverse attachment wall which connects its walls side, said transverse wall may also include a set of transverse or longitudinal teeth.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples.Of course, the invention is not limited to the modes of realization described and represented as examples.
