Description

La présente invention concerne une chaussure de ski de fond, notamment pour la pratique du pas de patineur (skating) obtenue à partir d'une semelle externe, destinée à être fixée sur le ski par sa partie avant de laquelle, et comportant une tige basse munie d'un contrefort arrière sur lequel est articulé un collier rigide destiné à entourer le bas de jambe, et qui s'étend vers le haut de la tige à partir de l'articulation, au-delà de l' extrémité supérieure de celle-ci.The present invention relates to a cross-country ski boot, in particular for the practice of skating step (skating) obtained from an external sole, intended to be fixed on the ski by its front part of which, and comprising a low rod provided with a rear buttress on which is articulated a rigid collar intended to surround the lower leg, and which extends towards the top of the rod from the articulation, beyond the upper end of the latter this.

Dans la pratique d'un tel sport lorsque le skieur de skating finit sa propulsion sur l'un des skis, il transfert son poids sur l'autre ski opposé, et ramène le premier ski au niveau du second.In the practice of such a sport when the skating skier finishes his propulsion on one of the skis, he transfers his weight to the other opposite ski, and brings the first ski back to the level of the second.

Ce ramené est différent selon :

  • la vitesse (donc le pas utilisé). En effet, plus la vitesse est faible plus la fréquence de patinage est élevée et donc moins le skieur a de temps pour ramener son ski. C'est pourquoi, plus la vitesse est faible moins les skis sont ramenés parallèles, et plus le skieur garde une divergence importante entre les deux skis.
  • la pente rencontrée. En effet, le skieur doit ramener son ski le plus parallèlement possible par rapport à la pente afin de ne pas trop le soulever. L'inclinaison du ski durant le ramené dépend donc de la pente rencontrée (ce qui rend le ramené particulièrement exigeant et difficile dans les fortes pentes).
This brought back is different according to:
  • speed (therefore the step used). In fact, the lower the speed, the higher the frequency of skating and therefore the less time the skier has to bring back his ski. This is why, the lower the speed, the less the skis are brought back parallel, and the more the skier keeps a significant divergence between the two skis.
  • the slope encountered. Indeed, the skier must bring his ski as parallel as possible to the slope so as not to lift it too much. The slope of the ski during the return therefore depends on the slope encountered (which makes the return particularly demanding and difficult on steep slopes).

Ces différentes constatations ont conduit à étudier le problème de ramené du ski dans la pratique du skating.These various observations have led to studying the problem of bringing back skiing in the practice of skating.

Les critères retenus d'évaluation du problème sont : le dégagement du ski, le contrôle en l'air du ski et la pose du ski.The criteria used to assess the problem are: clearing the ski, checking the air in the ski and fitting the ski.

Cette étude a révélé en fait que lors du dégagement du ski, l'extrémité avant ou spatule de celui-ci accroche dans la neige, ce qui provoque le véritable problème résidant dans le contrôle angulaire longitudinal du ski en phase quasi statique, c'est-à-dire en l'air.This study revealed in fact that during the release of the ski, the front end or tip of it hangs in the snow, which causes the real problem residing in the longitudinal angular control of the ski in quasi static phase, it is that is to say in the air.

Le problème étant ainsi posé, il a été également constaté qu'il en résultait une conséquence consistant pour le skieur, à devoir augmenter la contraction du jambier antérieur pour relever le ski et éviter l'accrochage de la spatule dans la neige pendant la phase de ramené du ski. Ceci est d'autant plus néfaste pour le skieur qu'il faudrait au contraire profiter de cette phase pour décontracter au maximum les muscles de la jambe concernée, car il s'agit en l'occurence d'une phase de repos et non motrice.The problem thus being posed, it was also noted that this resulted in a consistent consequence for the skier, having to increase the contraction of the anterior leg to raise the ski and avoid the attachment of the tip in the snow during the phase of brought back from skiing. This is all the more harmful for the skier as it should, on the contrary, take advantage of this phase to relax the muscles of the leg concerned as much as possible, since in this case it is a rest phase and not a motor phase.

La présente invention a pour but de remédier à ces inconvénients à partir du problème posé, et concerne à cet effet une chaussure du type précité se caractérisant en ce qu'elle comporte des moyens élastiques de contrôle angulaire longitudinal du ski en l'air, par rapport à la semelle de la chaussure, pendant la phase de ramené du ski.The object of the present invention is to remedy these drawbacks on the basis of the problem posed, and for this purpose relates to a shoe of the aforementioned type, characterized in that it comprises elastic means for longitudinal angular control of the ski in the air, by compared to the sole of the boot, during the return phase of the ski.

De tels moyens consistent en fait en une énergie de rappel entre le collier articulé et la tige offrant avantageusement une assistance efficace du jambier dans cette phase de la pratique du skating.Such means consist in fact of a return energy between the articulated collar and the rod advantageously offering effective assistance of the leg in this phase of the practice of skating.

Il en résulte ainsi une fatigue moindre pour le skieur qui ménage ses muscles.This results in less fatigue for the skier who spares his muscles.

Egalement grâce à ces moyens selon l'invention, la sensation de lourdeur du ski au niveau de la spatule s'en trouve allégée notablement, et l'on assure un meilleur maintien antéro-postérieur ainsi qu'un ramené du ski plus facile, la relance s'effectue alors dans de meilleures conditions car la fatigue est moindre.Also thanks to these means according to the invention, the feeling of heaviness of the ski at the level of the tip is considerably reduced, and better anteroposterior support is provided as well as easier reduction of the ski, the recovery is then carried out in better conditions because the fatigue is less.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre donnée à titre d'exemples non limitatifs et qui fera mieux comprendre comment l'invention peut-être réalisée en regard des dessins annexés sur lesquels :

  • la figure 1 est une vue de côté d'une chaussure de skating selon l'invention montée sur un ski.
  • les figures 2, 3, 4 illustrent, vue de côté, différents modes de réalisation de l'invention.
Other characteristics and advantages of the invention will appear during the description which follows given by way of nonlimiting examples and which will make it easier to understand how the invention can be produced with reference to the attached drawings in which:
  • Figure 1 is a side view of a skating shoe according to the invention mounted on a ski.
  • Figures 2, 3, 4 illustrate, side view, different embodiments of the invention.

La chaussure représentée, à titre d'exemple, sur la figure 1 est particulièrement adaptée pour le pas de patineur ou skating et présente, extérieurement, l'allure d'une chaussure constituée à l'origine d'une tige basse 10, c'est-à-dire d'une tige dont les parties rigides ne s'étendent pas en hauteur au-delà des malléoles d'une semelle externe 11 et d'un système de fermeture 20 pour le chaussage ou le déchaussage de type connu en soi recouvrant un système de laçage interne.The shoe shown, by way of example, in FIG. 1 is particularly suitable for skating or skating and has, externally, the appearance of a shoe originally made up of a low rod 10, c ' that is to say a rod whose rigid parts do not extend in height beyond the malleoli of an outer sole 11 and a closure system 20 for putting on or taking off the type known per se covering an internal lacing system.

De manière classique un ski 30 est fixé à une partie avant 11a de la semelle 11 par l'intermédiaire d'une fixation 16 représentée schématiquement.Conventionally, a ski 30 is fixed to a front part 11a of the sole 11 by means of a fixing 16 shown diagrammatically.

La tige 10 est en matériau souple et est munie au niveau du talon d'un contrefort arrière 12 pouvant être réalisé de toute façon connue en soi.The rod 10 is made of flexible material and is provided at the heel with a rear buttress 12 which can be produced in any way known per se.

Ce contrefort 12 est de préférence réalisé en matière synthétique rigide et s'étend sur toute la partie arrière de la chaussure tout autour du talon de celle-ci.This buttress 12 is preferably made of rigid synthetic material and extends over the entire rear part of the shoe all around the heel thereof.

Ce contrefort 12 s'étend, dans la zone des malléoles, jusqu'en haut de la tige 10 pour la réception d'un collier articulé 13, et présente à son extrémité supérieure, au niveau de ces malléoles, de chaque côté de la chaussure, une saillie ou bossage (non visible) s'étendant vers l'extérieur sensiblement perpendiculairement à la paroi du contrefort et apte à être introduit dans un trou cylindrique associé et ménagé sur chaque côté du collier et recevant un cou par exemple, apte à constituer une articulation 14.This buttress 12 extends, in the region of the malleoli, to the top of the rod 10 for receiving an articulated collar 13, and has at its upper end, at the level of these malleoli, on each side of the shoe , a projection or boss (not visible) extending outward substantially perpendicular to the wall of the buttress and adapted to be introduced into an associated cylindrical hole formed on each side of the collar and receiving a neck for example, capable of constituting an articulation 14.

Par cette disposition le collier 13 peut donc être monté articulé sur les parties en salle du contrefort 12 de la tige 10 à l'extrémité supérieure de celle-ci.By this arrangement the collar 13 can therefore be hinged mounted on the room parts of the buttress 12 of the rod 10 at the upper end thereof.

Les têtes des clous, une fois engagées dans les clous servent d'arrêt au collier 13, tandis que les bossages matérialisent l'axe d'articulation de ce collier 13 sur la tige 10.The heads of the nails, once engaged in the nails serve to stop the collar 13, while the bosses materialize the axis of articulation of this collar 13 on the rod 10.

On notera que les clous peuvent être remplacés par tous autres modes de liaison permettant une rotation telle que des rivets. Cependant, l'utilisation de clous est particulièrement avantageuse, car elle permet une pose par simple application d'une pression sur la tête, sans nécessiter de contre-pièces comme dans le cas des rivets.It will be noted that the nails can be replaced by any other connection method allowing rotation such as rivets. However, the use of nails is particularly advantageous, because it allows installation by simple application of pressure on the head, without requiring counterparts as in the case of rivets.

Le collier articulé 13 est constitué par une manchette en matériau rigide et notamment en un matériau synthétique tel que du Poly (ether-bloc-amide) Pébax.The articulated collar 13 is constituted by a cuff made of rigid material and in particular of a synthetic material such as Poly (ether-block-amide) Pébax.

Ce collier 13 s'étend vers le haut jusqu'au bas du mollet et entoure tout le bas de jambe. Il est ouvert à sa partie avant pour permettre la mise en place du pied dans la chaussure et est également muni de moyens de serrage 15 de type connu en soi et constitué par exemple par des moyens auto-agrippants.This collar 13 extends up to the bottom of the calf and surrounds the entire lower leg. It is open at its front part to allow the foot to be placed in the shoe and is also provided with clamping means 15 of a type known per se and constituted for example by hook-and-loop means.

Ce collier 13 est par ailleurs muni à l'arrière d'une échancrure 13a destinée à faciliter la rotation vers l'arrière de ce collier.This collar 13 is also provided at the rear with a notch 13a intended to facilitate the rearward rotation of this collar.

Ainsi qu'on le concevra aisément, la hauteur importante du collier 13 permet une excellente tenue latérale de la jambe lors de la pratique du skating, une telle hauteur permettant en outre une plus grande répartition sur la jambe des efforts de réaction et, par conséquent, un meilleur confort pour l'utilisateur.As will be readily appreciated, the large height of the collar 13 allows excellent lateral holding of the leg during skating, such a height also allowing greater distribution of the reaction forces over the leg and, consequently, , better comfort for the user.

Par ailleurs la chaussure de skating selon l'invention comporte également des moyens élastiques 40 de contrôle angulaire longitudinal du ski 30, lorsqu'il est en l'air, par rapport à la semelle 11 de la chaussure pendant la phase de ramené dudit ski 30 permettant de remédier à certains inconvénients rencontrés dans la pratique du skating et qui ont été énoncés ci-dessus.Furthermore, the skating shoe according to the invention also comprises elastic means 40 for longitudinal angular control of the ski 30, when it is in the air, relative to the sole 11 of the shoe during the phase of bringing back said ski 30 allowing to remedy certain drawbacks encountered in the practice of skating and which have been stated above.

Ces moyens 40 sont, dans le ces de la figure 1, disposés entre une zone arrière du collier 13 de la chaussure et une partie inférieure de la tige basse 10, à proximité de la semelle 11 et comprennent deux organes élastiques 41 disposés symétriquement de part et d'autre de la chaussure le long de ses flancs et constituant une source d'énergie desdits moyens de contrôle, qui est appliquée au collier articulé 13 par rapport à la tige basse 10 afin de soumettre celle-ci à une contrainte élastique permanente tendant à rappeler ladite tige 10 vers le collier articulé 13 dans un mouvement de pivotement vers le haut dans le sens F1 provoquant conséquemment le relevage automatique de l'extrémité avant ou spatule 30a du ski 30, lorsque celui-ci n'est pas dans une phase motrice.These means 40 are, in the FIG. 1, arranged between a rear zone of the collar 13 of the shoe and a lower part of the lower upper 10, near the sole 11 and comprise two elastic members 41 arranged symmetrically apart. and other of the shoe along its sides and constituting a source of energy of said control means, which is applied to the articulated collar 13 with respect to the low upper 10 in order to subject the latter to a permanent elastic stress tending to recall said rod 10 towards the articulated collar 13 in an upward pivoting movement in the direction F1 consequently causing the automatic lifting of the front end or tip 30a of the ski 30, when the latter is not in a phase motor.

Dans ce cas de figure, chaque organe élastique 41 est constitué par une bride en tissu élastique dont l'une des extrémités 41a est cousue sur le flanc 10a de la tige basse 10 approximativement à mi longueur de la chaussure, par des coutures 41b, alors que l'autre extrémité 41c passe librement dans une boucle fixe 42 fixée sur le flanc 13b du collier 13. Après passage dans la boucle 42, l'extrémité 41c de la bride 41 se referme sur elle-même par tous moyens de fixation, selon une tension élastique choisie.In this case, each elastic member 41 is constituted by an elastic fabric flange, one of the ends 41a of which is sewn onto the side 10a of the low upper 10 approximately at mid-length of the shoe, by seams 41b, then the other end 41c passes freely in a fixed loop 42 fixed on the side 13b of the collar 13. After passing through the loop 42, the end 41c of the flange 41 closes on itself by any fixing means, according to a chosen elastic tension.

En l'occurence les moyens de fixation de la bride élastique 41 sont constitués par une pluralité de boutons pressions 43 constitués de manière connue de deux parties mâle et femelle respectivement 43a et 43b complémentaires dont l'une d'elles, femelle, 43b est située à proximité de l'extrémité 41c de la bride 41 et coopère avec l'une des autres mâles 43a disposées alternativement le long d'une zone intermédiaire de la bride 41 pour permettre une fixation avec réglage selon la tension souhaitée, après passage de l'extrémité 41c dans la boucle 42, les positions des éléments mâles et femelles pouvant être inversées.In this case, the means for fixing the elastic flange 41 are constituted by a plurality of snaps 43 constituted in a known manner of two complementary male and female parts 43a and 43b, one of which, female, 43b is located near the end 41c of the flange 41 and cooperates with one of the other males 43a arranged alternately along an intermediate zone of the flange 41 to allow fixing with adjustment according to the desired tension, after passage of the end 41c in the loop 42, the positions of the male and female elements can be reversed.

Bien entendu, les moyens de fixation de la bride élastique 41 peuvent également être constitués par des segments de matériaux auto-agrippants rapportés sur ladite bride élastique 41 selon une longueur même de façon à permettre son réglage pour l'obtention d'une tension choisie. D'autres modes de fixation avec réglage peuvent également être prévus.Of course, the means for fixing the elastic flange 41 can also be constituted by segments of self-gripping materials attached to said elastic flange 41 along a same length so as to allow its adjustment to obtain a chosen tension. Other fixing methods with adjustment can also be provided.

Selon une variante d'exécution, représentée sur la figure 2, les moyens élastiques 40A sont constitués par un organe élastique 50, qui est constitué par un ressort métallique obtenu à partir d'un élément filiforme formant une boucle 50a dans une zone intermédiaire, et à partir de laquelle sont issues deux branches élastiques 50b, 50c engagées sous contrainte derrière deux butées de retenue fixes 51, 52, ces butées étant disposées respectivement sur au moins un flanc 13b du collier 13, et sur au moins un flanc 10a de la tige 10 vers sa partie arrière. De cette manière, l'organe élastique 50 se trouve en précontrainte permanente tendant à toujours ramener la tige 10 vers le collier 13 dans le sens F1 aidant comme dans l'exemple précédent, le relevage de la spatule 30a du ski 30 dans la phase de ramené.According to an alternative embodiment, shown in FIG. 2, the elastic means 40A are constituted by an elastic member 50, which is constituted by a metal spring obtained from a filiform element forming a loop 50a in an intermediate zone, and from which come two elastic branches 50b, 50c engaged under stress behind two fixed retaining stops 51, 52, these stops being disposed respectively on at least one side 13b of the collar 13, and on at least one side 10a of the rod 10 towards its rear part. In this way, the elastic member 50 is in permanent prestressing, tending to always bring the rod 10 towards the collar 13 in the direction F1 helping, as in the previous example, the raising of the tip 30a of the ski 30 in the phase of brings back.

Selon une autre variante d'exécution représentée à la figure 3, les moyens élastiques 40B sont constitués par un ressort métallique 60 agissant en compression et disposé entre une butée 12a ménagée sur une partie arrière du contrefort 12 de la tige 10 et une butée 13c ménagée en correspondance sur le collier 13. Selon cette configuration, le ressort 60 agit en compression sur l'arrière de la tige 10 dans un sens F2, se traduisant par un relevé de la spatule 30a dans le sens F1 recherché.According to another alternative embodiment represented in FIG. 3, the elastic means 40B consist of a metal spring 60 acting in compression and disposed between a stop 12a formed on a rear part of the buttress 12 of the rod 10 and a stop 13c formed in correspondence on the collar 13. According to this configuration, the spring 60 acts in compression on the rear of the rod 10 in a direction F2, resulting in a reading of the tip 30a in the direction F1 sought.
