Abstract

A boot for gliding sports, and more specifically, for "snowboarding". The boot includes two distinct zones with different characteristics and functions, including a first relatively rigid energy/power circuit, distributed with respect to the foot, so as to centralize the forces, and especially the front and rear supports or the torsion control, during practice of the sport, and a second relatively flexible, sensitive circuit independent of the energy/power circuit, and adapted to ensure comfort of the foot as well as transmission of information originating from the gliding member towards the ankle. Both of the circuits are affixed to a common reference element.

Description

La présente invention concerne une chaussure destinée aux sports de glisse, dans lesquels le pied est lié à l'organe de glisse par l'intermédiaire d'une chaussure, et plus particulièrement une chaussure adaptée à la pratique du surf sur la neige ou "snow board" ou également à la pratique du patin, patin à glace, patin en ligne ou ski (ski de fond, télémark......). La pratique de ce type de sport a mis en évidence des problèmes liés à la construction des chaussures existantes à l'heure actuelle, et qui ne répondent pas aux sollicitations dynamiques, induites par ces sports.The present invention relates to a shoe intended for sports slides, in which the foot is linked to the sliding member by through a shoe, and more particularly a shoe suitable for snowboarding or snowboarding or also skating, ice skating, inline skating or skiing (cross-country skiing, telemark ......). The practice of this type of sport has highlighted problems with building existing shoes on time current, and which do not respond to dynamic requests, induced by these sports.

En effet, il s'avère nécessaire de garantir au pied un certain confort et une certaine tenue souple et de lui permettre de prendre des positions diverses en fonction des situations rencontrées ou souhaitées au cours de la glisse.Indeed, it proves necessary to guarantee a certain comfort to the foot and some flexible holding and allowing him to take various positions depending on the situations encountered or desired during the slide.

Contradictoirement, il se révèle tout aussi nécessaire de garantir au pied et au bas de jambe d'un utilisateur, des appuis rigides qui doivent être d'autant plus puissants que l'organe de glisse (patin, snow board) est d'une taille plus importante ou que la glisse est le plus souvent effectuée de manière rapide et selon des figures plus ou moins acrobatiques.Conversely, it is just as necessary to guarantee a user's foot and lower leg, rigid supports which must be all the more powerful as the gliding device (skate, snow board) is larger or the glide is most often performed quickly and according to figures more or less acrobatics.

Dans ces conditions, les bras de levier résultant des dimensions de l'organe de glisse induisent sur le pied ou le bas de jambe des efforts qui sont parfois très importants et le pied ou le bas de jambe demandent donc également à être fermement maintenus, selon des axes d'appui vers l'avant ou vers l'arrière, mais aussi latéralement et en torsion, ces exigences de maintien ferme étant antinomiques avec la notion de confort.Under these conditions, the lever arms resulting from the dimensions of the sliding device induces stress on the foot or lower leg which are sometimes very important and the foot or lower leg therefore also require to be firmly maintained, along axes support forwards or backwards, but also laterally and in torsion, these firm holding requirements being in conflict with the concept of comfort.

A l'heure actuelle, il est proposé sur le marché des chaussures soit de construction souple, soit de construction rigide ou semi rigide.At the present time, it is offered on the market for either flexible construction, either rigid or semi-rigid construction.

Concernant les chaussures souples, celles-ci assurent généralement la tenue du pied par déformation de la tige (cuir, tissu, plastique souple), en rapprochant celle-ci du pied par un système de laçage, tendant à appliquer le pied contre la semelle de la chaussure ou encore par un dispositif de serrage interne, plaquant le pied contre la semelle indépendamment de la tige externe.Regarding flexible shoes, these generally provide the hold of the foot by deformation of the upper (leather, fabric, plastic flexible), by bringing it closer to the foot by a lacing system, tending to apply the foot against the sole of the shoe or by an internal clamping device, pressing the foot against the sole regardless of the outer rod.

Concernant les chaussures rigides ou semi-rigides telles que celles développées pour le ski alpin, plus snow board, patin à glace ou patin en ligne, celles-ci comportent un chausson interne enveloppant le pied et le bas de jambe et lui même disposé dans une coque en plastique ou en cuir rigide.Regarding rigid or semi-rigid shoes such as those developed for alpine skiing, plus snow board, ice skating or skating in line, these include an internal liner enveloping the foot and the lower leg and itself arranged in a plastic shell or in rigid leather.

Une telle chaussure est divulguée par exemple par le document WO 90/05466.Such a shoe is disclosed for example by the document WO 05/05 466.

Le pied est alors tenu fermement par l'intermédiaire du chausson, soit par la déformation relative de la coque qui met sous contrainte ledit chausson et tend à l'immobiliser par l'intermédiaire d'organes de fermeture externe de la coque tels que des crochets et/ou un collier sur le bas de jambe, soit encore par des dispositifs de serrage internes à la coque et qui tendent également à immobiliser le chausson par rapport à la semelle tout en l'éloignant de ladite coque et cela par l'intermédiaire de cables et de plaques d'appui, commandés depuis l'extérieur de la chaussure par des organes de fermeture et de réglage.The foot is then held firmly by the slipper, either by the relative deformation of the shell which puts under stress said shoe and tends to immobilize it by means of external closure of the shell such as hooks and / or a collar on the lower leg, again by internal clamping devices at the shell and which also tend to immobilize the liner relative to the sole while moving it away from said shell and this via cables and support plates, controlled from outside the shoe by closing and adjusting members.

Chacun de ces types de chaussures connues qui viennnent d'être citées présente des avantages et des inconvénients qui leur sont propres et qui sont indissociables.Each of these known types of shoes which have just been mentioned has its own advantages and disadvantages which are inseparable.

En effet, si dans les chaussures souples, le pied et le bas de jambe sont très bien liés à la semelle grâce au serrage à l'aide de matériaux souples, ce qui procure une bonne transmission des informations en provenance de l'organe de glisse, en revanche les appuis sont peu puissants voire inexistants du tait de la souplesse de la tige, ce qui d'ailleurs peut s'avérer dangereux ou fatigant pour la résistance du pied et du bas de jambe qui auront à compenser, par des efforts plus importants, ce manque d'appui.Indeed, if in flexible shoes, the foot and the lower leg are very well linked to the sole thanks to the tightening using materials flexible, which provides good information transmission in origin of the sliding member, on the other hand the supports are little powerful or even non-existent was the flexibility of the stem, which moreover can be dangerous or tiring for the resistance of the foot and lower leg which will have to compensate, by more efforts important, this lack of support.

A l'inverse dans les chaussures rigides, il n'y a pas à souffrir du manque d'appuis mais par contre le pied est moins bien tenu dans la chaussure du fait des mouvements relatifs possibles entre la coque et chausson et donc entre le chausson et la semelle, à moins de déformer très fortement la coque sur le chausson ce qui génère de fortes pressions néfastes sur le pied et donc de l'inconfort.Conversely in rigid shoes, there is no need to suffer from lack of support but on the other hand the foot is less well held in the shoe due to possible relative movements between the shell and liner and therefore between the liner and the sole, unless it deforms very strongly the shell on the liner which generates strong harmful pressure on the foot and therefore discomfort.

Autrement dit, les prises d'appuis nécessitent d'utiliser des pièces ou parties rigides qui sont difficilement compatibles avec une adaptation précise à la morphologie du pied, nécessaire au confort à la tenue de pied et à la bonne transmission d'informations.In other words, support holds require the use of parts or rigid parts which are hardly compatible with an adaptation precise to the morphology of the foot, necessary for comfort when holding foot and good transmission of information.

Il a été démontré là, selon une première phase de la démarche inventive que tous les problèmes ne peuvent être traités ensembles dans les mêmes zones de la chaussure et que par conséquent ils devront être traités de manières distinctes, la tenue souple du pied et du bas de jambe ne devant pas avoir d'interférence sur les appuis rigides, afin de limiter la complexité de la chaussure à mettre au point selon ces critères et faisant l'objet de la présente invention. It was demonstrated there, according to a first phase of the process inventive that not all problems can be tackled together in the same areas of the shoe and therefore they will have to be treated in different ways, the flexible holding of the foot and the bottom of leg should not interfere with rigid supports, in order to limit the complexity of the shoe to be developed according to these criteria and subject of the present invention.

A cet effet l'invention concerne une chaussure de sport de glisse, telle que définie dans chacune des revendications indépendantes 1 et 5 correspondant à quatre modes de réalisation.To this end, the invention relates to a sliding sports shoe, as defined in each of independent claims 1 and 5 corresponding to four embodiments.

De cette façon, la chaussure selon l'invention cumule en fait les avantages des chaussures souples et rigides tout en dissociant le traitement géographique des deux critères recherchés tenue de pied souple et prise d'appui rigide. Par ailleurs, la liaison de chacun des circuits à un élément commun de référence permet de remédier aux problèmes évoqués ci-avant de mouvements relatifs générant une mauvaise tenue de pied.In this way, the shoe according to the invention actually combines the advantages of flexible and rigid shoes while dissociating the geographic treatment of the two criteria sought flexible and rigid support. In addition, the connection of each of the circuits with a common reference element makes it possible to remedy the problems mentioned above of relative movements generating a poor footing.

L'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit, en référence aux dessins schématiques annexés, illustrant, à titre d'exemple non limitatif, comment l'invention peut-être réalisée et dans lesquels :

    • The invention will be better understood and other characteristics thereof will be highlighted with the aid of the description which follows, with reference to the appended schematic drawings, illustrating, by way of nonlimiting example, how the invention can be carried out and in which:
  • - Figure 1 schematically shows a power circuit, alone, constituting a sub-assembly of a shoe to be produced, according to the invention.

    • La chaussure de sport de glisse 1 désignée dans son ensemble aux figures 1 et 2 est en l'occurrence une chaussure destinée à la pratique du patin, patin à glace, patin en ligne, ski (ski de fond, télémark......) ou encore au surf sur la neige ou snow board.The sliding sports shoe 1 designated as a whole to Figures 1 and 2 is in this case a shoe intended for practice skating, ice skating, inline skating, skiing (cross-country skiing, telemark ......) or still surfing on snow or snow board.

    Elle est constituée globalement, d'une part, par un circuit de puissance 2, 2A, 2B, 2C, 2D, 2E, 2F et 5, relativement rigide, réparti par rapport au pied, de manière à centraliser les efforts et notamment les reprises d'appui avant et arrière ou le contrôle de la torsion pendant la pratique du sport, et d'autre part, par un circuit sensitif 3, 3A, 3B relativement souple, indépendant du circuit de puissance cité, et apte à assurer le confort du pied et la transmission d'information en provenance de l'organe de glisse (non représenté sur le dessin) vers les zones sensitives du pied et notamment la cheville et le cou de pied, l'un et l'autre des circuits 2, 3 étant fixés à un élément de référence commun.It is made up, on the one hand, by a circuit of power 2, 2A, 2B, 2C, 2D, 2E, 2F and 5, relatively rigid, distributed by relation to the foot, so as to centralize the efforts and in particular the front and rear support or torsion control during the practice of sport, and on the other hand, by a sensitive circuit 3, 3A, 3B relatively flexible, independent of the cited power circuit, and capable of ensure foot comfort and information transmission in origin of the sliding member (not shown in the drawing) towards the sensitive areas of the foot and in particular the ankle and the instep, one and the other of circuits 2, 3 being fixed to a reference element common.

    En l'occurrence cet élément de référence commun est constitué par une semelle 5 relativement rigide de la chaussure 1, qui est destinée à être reliée à l'organe de glisse 4 et de toute autre partie attenante de cette semelle, formant une partie intrinsèque du circuit de puissance.In this case, this common reference element consists of a relatively rigid sole 5 of the shoe 1, which is intended to be connected to the sliding member 4 and any other adjoining part of this sole, forming an intrinsic part of the power circuit.

    La semelle 5 comporte par ailleurs des surfaces d'accrochage destinées à coopérer avec des moyens de fixation de l'organe de glisse 4 constitués par exemple par des étriers 6 (cf figure 4).The sole 5 also has hooking surfaces intended to cooperate with means for fixing the sliding member 4 constituted for example by stirrups 6 (see Figure 4).

    Comme cela est particulièrement clairement représenté sur la figure 1, le circuit de puissance rigide est constitué, outre la semelle 5, par une coque formant sabot 2A solidaire de ladite semelle 5 et comportant un contrefort arrière 2B apte à envelopper le talon et une butée avant 2C, ledit contrefort 2B étant prolongé vers la cheville et le bas de jambe par un collier 2D comportant des moyens de serrage 7 pour la tenue du bas de jambe.As is particularly clearly shown in the figure 1, the rigid power circuit is constituted, in addition to the sole 5, by a shell forming a shoe 2A integral with said sole 5 and comprising a rear buttress 2B capable of wrapping the heel and a front stop 2C, said buttress 2B being extended towards the ankle and the bottom of leg by a 2D collar comprising clamping means 7 for the lower leg hold.

    Préférentiellement, le collier 2D est articulé en 8 à sa partie postérieure inférieure a sur une partie associée b du contrefort 2B. Preferably, the 2D collar is articulated at 8 in its part posterior lower a on an associated part b of the buttress 2B.

    Plus précisément, dans l'exemple représenté sur les figures 1 et 2, l'articulation 8 est un axe transversal arrière situé dans la zone a d'extrémité inférieure du collier 2D et dans la zone centrale arrière b du contrefort 2B.More specifically, in the example shown in FIGS. 1 and 2, joint 8 is a rear transverse axis located in zone a of the lower end of the 2D collar and in the rear central area b buttress 2B.

    Dans le cas de la figure 1, le collier 2D est relié au sabot 2A ou à la semelle 5 qui en est solidaire par au moins un tirant latéral relativement rigide 2E pour constituer un appui avant ou un appui arrière de la jambe selon la position de la jambe par rapport à l'organe de glisse 4, de manière à mieux contrôler les efforts et les courses en latéral, en torsion et selon des mouvements arrière et avant du collier 2D par rapport au sabot 2A.In the case of FIG. 1, the 2D collar is connected to the shoe 2A or to the sole 5 which is secured to it by at least one lateral tie rod relatively rigid 2E to constitute a front support or a support back of the leg according to the position of the leg relative to the organ glide 4, so as to better control the forces and strokes in lateral, in torsion and according to back and front movements of the collar 2D compared to shoe 2A.

    Selon une variante illustrée à la figure 2, le collier 2D est relié au sabot 2A ou à la semelle 5 qui en est solidaire par au moins une sangle souple 2F formant hauban apte à constituer en tension, un appui arrière, alors que l'appui avant de la jambe est obtenu par un prolongement vers le haut c du contrefort arrière 2B du sabot 2A enveloppant le talon qui s'étend au-delà de l'articulation 8 du collier 2D. Ainsi la partie correspondante a du collier D prend appui sur le prolongement dans un sens de flexion postéro-antérieur de la jambe pour consituer l'appui avant.According to a variant illustrated in Figure 2, the 2D collar is connected to the shoe 2A or sole 5 which is secured to it by at least one strap flexible 2F forming a shroud capable of constituting in tension, a rear support, while the front leg support is obtained by an extension towards the top c of the rear buttress 2B of the shoe 2A enveloping the heel which extends beyond the joint 8 of the 2D collar. So the part corresponding to collar D rests on the extension in a posterior-anterior flexion of the leg to provide support before.

    Selon une variante de réalisation illustrée à la figure 3, le collier 2D1 est articulé à sa partie inférieure d sur deux axes d'articulation 9 situés sur les parties latérales du contrefort arrière 2B1 du sabot 2A1, dans la zone des malléoles du pied, les appuis avant et arrière s'effectuant au moyen d'une liaison 19 entre une partie arrière e dudit collier sur une partie supérieure arrière f du contrefort. La liaison entre ces deux parties e, f est avantageusement obtenue à l'aide d'une goupille 19 amovible, ce qui permet l'ouverture du collier par pivotement autour de ses axes 9 pour le chaussage ou la marche à pied.According to an alternative embodiment illustrated in Figure 3, the collar 2D1 is articulated at its lower part d on two axes of articulation 9 located on the lateral parts of the rear buttress 2B1 of the shoe 2A1, in the malleolus area of the foot, the front and rear supports by means of a link 19 between a rear part e of said collar on a rear upper part f of the buttress. The link between these two parts e, f is advantageously obtained using a removable pin 19, which allows the opening of the collar by pivoting around its axes 9 for putting on or walking.

    Selon la variante de réalisation représentée sur les figures 4 et 6, le collier 2D2 est articulé à sa partie arrière inférieure h sur un axe d'articulation 10 disposé à l'arrière d'une zone i du contrefort 2B2 du sabot 2A2. Dans ce cas la prise d'appui avant s'effectue par mise en contact d'un rebord inférieur j du collier 2D2 sur un rebord supérieur k du sabot 2A2, et la prise d'appui arrière est obtenue par l'intermédiaire d'un tirant 2F interposé entre le sabot 2A2 et le collier 2D2.According to the variant embodiment shown in Figures 4 and 6, the 2D2 collar is articulated at its lower rear part h on an axis hinge 10 disposed at the rear of a zone i of the buttress 2B2 of the shoe 2A2.
