Description

Le domaine de l'invention est celui des chaussures de ski dans lesquelles di moyens spéciaux sont prévus pour le maintien du pied dans la chaussure. The field of the invention is that of ski boots in which di special means are provided for maintaining the foot in the shoe.

Selon des réalisations déjà connues, par ex. According to previously known embodiments, eg. le brevet français 2.204.106, existe des chaussures de ski pourvues d'un sac intérieur à double paroi, aye pour but de maintenir le pied à l'intérieur de la coque externe rigide. French Patent 2,204,106, there ski boots provided with an inner bag double wall aye intended to hold the foot inside the rigid outer shell.

Ce sac est fixé à la partie supérieure de la coque, et il est rempli d'un mélange réactionnel gonflant, généralement du type polyuréthanne ou du type latex expansible de caoutchouc. This bag is attached to the upper part of the shell, and is filled with a foaming reaction mixture, typically polyurethane or the expandable latex rubber.

Toutefois dans la pratique, lors de l'expansion du mélange réactionnel, le sn épouse pas aussi parfaitement les extrémités du pied qu'on pourrait le cro et par conséquent à ces endroits particulièrement importants, le pied ne reç pas de butée significative, et peut donc se déplacer pour prendre une positi incorrecte dans la chaussure aux moments où les efforts les plus violents so exercés. However in practice, during the expansion of the reaction mixture, sn not as perfectly marries the ends of the foot as you might cro and therefore particularly important to these places, the foot does not stop REC significant and can thus move to take incorrect positi in the shoe to the times when the most violent efforts so exercised.

D'autres réalisations comportent des coussins gonflables à l'air, c1 est le c par exemple des brevets canadiens nO 951.117 et 951.118, du certificat d'uti français n" 2.356.384 et du brevet français nO 2.252.820. Other achievements include airbags air, c1 is the c example of Canadian patents nO 951 117 and 951 118, the French certificate of uti n "2356384 and the French patent nO 2,252,820.

Dans ce dernier est décrite une chaussure équipée d'un coussin constitué de deux ailes latérales attachées à un coussin central gonflables au moyen d'un pompe à piston incorporée à la chaussure. In the latter there is disclosed a shoe equipped with a cushion formed of two lateral wings attached to a central inflatable cushion by means of a piston pump incorporated in the shoe. Les coussins latéraux maintiennent cheville, mais exercent surtout leur pression le long du tendon d'Achille su lequel presse directement le coussin central. The side cushions keep ankle, but above all exert their pressure along the Achilles tendon which managed directly press the center cushion. La résultante des forces qu'il exercent presse le pied vers l'avant de la chaussure, accentuant l'effet de coincement du à l'assiette du pied, déjà négative vers l'avant. The resultant forces that exert press on foot toward the front of the shoe, highlighting the wedging effect of the base of the foot, already negative forward.

Le certificat d'utilité français nO 2.356.384 aboutit au même résultat avec coussins latéraux comme ci-dessus, et un coussin situé sous le pied, mais conformé en pointe, I'extrémité la plus épaisse se situant sous le talon et l'extrémité la plus mince au bout du pied. The French utility certificate nO 2,356,384 leads to the same result with side cushions as above, and a cushion located under the foot, but shaped in a point, I'extrémité thickest lying under the heel and the end the thinner the toe.

Dans la demande de brevet allemand DOS nO 2.365.329,on décrit une chaussure qui possède deux coussins latéraux comme ci-dessus et un coussin sous l'empei de la chaussure externe. In the German Offenlegungsschrift nO 2,365,329 describes a shoe which has two side cushions as above and a cushion under the empei of the outer boot.

Ce dernier coussin est introduit par une fente dans la chaussure, du genre Pc marsupiale et vient directement en contact du pied. This cushion is inserted through a slot in the shoe, the kind Pc marsupial and directly contacts the foot. Pour pouvoir le placer correctement jusqu'au bout du pied, une deuxieme fente est nécessaire pour ti l'extrémité avant de ce coussin. To place it correctly to the end of the foot, a second slot is needed to ti the front end of the cushion. Ces deux fentes sont des points faibles de 1 chaussure qu'il n'est pas possible de rendre absolument étanche. These two slots are weaknesses of shoe 1 that it is not possible to make absolutely tight.

La présente invention élimine les inconvénients des solutions de la technique antérieure énumérées ci-dessus. The present invention eliminates the disadvantages of the prior art solutions listed above. Son objet est une chaussure de ski munie d'arceaux et de boudins gonflables simultanément ou séparément selon que l'utilisateur veut skier ou marcher. Its object is a ski boot provided with arches and inflatable tubes simultaneously or separately depending on whether the user wants to ski or walk. Ces arceaux et boudins assurent le maintien du pied bien serré contre la semelle. These poles and rods provide foot support tightly against the sole.

Les boudins portés par l'intérieur de ces arceaux retiennent le pied dans son glissement vers l'avant et évitent l'effet de coincement. The flanges carried by the inside of these hoops hold the foot in its forward sliding and prevent the wedging effect.

Par ailleurs, l'inclinaison sur l'horizontale de l'arceau le plus proche du coude-pied fournit une composante horizontale importante au niveau de chacune des deux attaches de l'arceau sur la semelle. Moreover, the inclination to the horizontal of the nearest arch of the instep provides a large horizontal component at each of the two attachments of the hoop on the sole. Cette composante horizontale sert au maintien transversal du pied lors des mouvements brusques du skieur, par exemple lors des virages. This horizontal component is used for transverse retention of the foot during sudden movements of the skier, for example during cornering.

Enfin ces deux boudins permettent de loger dans une même chaussure (coque extérieure rigide) des pieds de pointures différentes, en jouant sur le taux de gonflage des dits boudins. Finally, these two tubes suitable for mounting in the same shoe (rigid outer shell) of the legs of different sizes, by varying the inflation rate of said strands.

D'autres caractéristiques et avantages de l'invention apparaitront au cours de la description qui suit, qui est illustrée de façon non limitative par les dessins annexés parmi lesquels la figure I représente en coupe de profil une chaussure de ski suivant l'invention à deux arceaux munis de boudins gonflables ; Other features and advantages of the invention appear from the following description, which is illustrated without limitation by the accompanying drawings in which Figure I shows in side sectional a ski boot according to the invention with two hoops provided with inflatable tubes; la figure 2 est une vue éclatée des différentes pièces constituant la chaussure ; Figure 2 is an exploded view of the different pieces constituting the shoe; la figure 3 est un schéma de principe du circuit de gonflage des boudins. Figure 3 is a block diagram of the strands inflation circuit.

Selon une réalisation préférée de l'invention, la chaussure de ski se compose d'une coque inférieure rigide ou sabot 1 sur laquelle s'articulent une coque supérieure mobile 2 ou jambiere et un contrefort 3. La jambiere 2 est montée sur le sabot I par l'intermédiaire de tourillons 13,14 ; In a preferred embodiment of the invention, the ski boot consists of a rigid lower shell or shoe 1 on which are articulated a movable upper shell 2 or 3. JAMBIERE and buttress the pad 2 is mounted on the shoe I via pins 13,14; le contrefort 3 par l'intermédiaire de glissières 15,16. the stiffener 3 via rails 15,16.

A l'intérieur du sabot 1 prend place une semelle 5 fixée à lui par I'intermé- diaire d'un tenon d'extrémité 19 et d'une vis 18 sous le talon. Inside the shoe 1 takes up a sole 5 fixed to it by I'intermé- mediary of an end stud 19 and a screw 18 under the heel.

Selon une réalisation préférée de l'invention deux arceaux gonflables, l'un dans la partie antérieure de la chaussure, l'autre dans la partie médiane de celle-ci sont solidaires de la semelle, dans l'épaisseur de laquelle se trouvent les canaux 20 d'amenée d'air sous pression produit par une pompe appropriée 1 1 incorporée à la chaussure. According to a preferred embodiment of the invention two inflatable arches, one in the front part of the boot, the other in the middle portion thereof is secured to the sole in the thickness of which the channels are located 20 pressurized air supply generated by a suitable pump 1 1 incorporated into the shoe. Cette pompe peut être conçue sur le meme principe que les gonfleurs d'appareils pneumatiques de plage. This pump can be designed on the same principle as the inflators range of pneumatic devices.

Ces deux arceaux viennent compenser exactement l'espace vide en forme de coin existant entre la coque externe et le chausson interne, dans lequel se trouve le pied. These two hoops are exactly compensate the empty space in the form of existing wedge between the outer shell and the inner shoe, wherein the foot is located.

Ce dernier se trouve ainsi maintenu vers l'avant et latéralement. The latter is thus kept forwardly and laterally.

Les arceaux gonflables se composent d'une armature proprement dite, 6,7, en matériau rigide ou semi-rigide tel que le cuir, le polypropylene etc... contenant, à l'intérieur de sa concavité, un boudin-en forme de demi-tore aplati,8,9. Inflatable arches consist of an actual reinforcement, 6,7, rigid or semi-rigid material such as leather, polypropylene etc ... containing, within its concavity, a coil-shaped half-flattened torus, 8.9.

Ces boudins 8,9 peuvent être gonflés à volonté par la pompe 11 simultanément ou séparément, et ceci constitue un objet de l'invention, par l'intermédiaire d'un clapet anti-retour 21 et d'un robinet à trois voies 22. These flanges 8,9 can be inflated at will by the pump 11 simultaneously or separately, and this is an object of the invention, via a check valve 21 and a three-way valve 22.

Le dégonflage peut intervenir de la même façon, simultanément ou séparément en utilisant le robinet à trois voies dans les positions adéquates, ainsi qu'unie valve de mise à l'air 23 qui est normalement fermée pendant l'utilisation de la chaussure sur skis. The deflation may occur in the same way, simultaneously or separately using the three-way valve in the appropriate positions, and qu'unie vent valve 23 which is normally closed during use of the shoe on skis.

Un avantage des chaussures selon l'invention est qu'elles permettent une marche aisée par mise à l'air du contenu de l'arceau médian, ce qui débloque le pied vers l'carrière et permet le débattement de celui-ci autour de la cheville pendant les mouvements de la marche. An advantage of the shoe according to the invention is that they allow easy operation by venting the contents of the central hoop, which unlocks the foot towards the career and allows the movement thereof to around the ankle during the movements of walking.

Un autre avantage des chaussures selon l'invention réside dans le fait que les deux boudins décollent le pied de la coque extérieure et l'isolent ainsi du froid. Another advantage of the shoe according to the invention lies in the fact that the two tubular take off the bottom of the outer shell and thus isolate the cold.

Bien que l'application décrite ici concerne les chaussures de ski, on comprend aisément que l'invention puisse aussi s'appliquer aux chaussures de patinage sur glace, bottes, chaussures de montagne, chaussures de hockey, bottes de motocyclette etc... sans pour autant sortir de son cadre. Although the application described herein relates to ski boots, one can easily understand that the invention may also be applied to ice skating shoes, boots, hiking boots, hockey shoes, motorcycle boots etc ... without thereby departing from its scope.
