Abstract

The plastic boot comprises a shell with a variable volume (1) having two longitudinal flaps (2, 3) which overlap each other over at least a part of the foot, and an upper in the form of a collar (7) articulated on the shell. Only the flap (3) on the inner side of the boot extends both over and at least partly above the instep. The missing part of the other flap (2) is replaced by an auxiliary piece (6) integral with a covering-over piece (5) enveloping the metatarso-phalangeal zone. Putting the boot on is thereby facilitated, whilst still ensuring satisfactory transmission of the forces of the leg on the internal side of the boot for edge gripping. <IMAGE>

Description

La présente invention a pour objet une chaussure de ski en matière plastique comprenant une coque à volume variable entourant le pied et le talon et présentant deux rabats longitudinaux se chevauchant sur au moins une partie du pied mais dont un seul s'étend à la fois sur et au-dessus le cou-de-pied, c'est-à-dire au niveau du bas de la jambe, une pièce auxiliaire rapportée coopérant avec ledit seul rabat pour recouvrir le cou-de-pied, une tige en forme de collier rapportée à la coque et des moyens de serrage de la coque et du collier.The present invention relates to a plastic ski boot comprising a variable volume shell surrounding the foot and the heel and having two longitudinal flaps overlapping on at least part of the foot but only one of which extends simultaneously and above the instep, that is to say at the level of the lower leg, an auxiliary attached piece cooperating with said single flap to cover the instep, a rod in the form of a collar attached to the shell and means for clamping the shell and the collar.

Du document EP-A-0 353 532, on connaît une chaussure de ce type, dans laquelle la pièce auxiliaire rapportée est constituée d'un volet fixé latéralement à la coque en un ou deux points et venant, d'une part, recouvrir le cou-de-pied avec le rabat de la coque s'étendant au-dessus du cou-de-pied et, d'autre part, recouvrir le bord transversal du rabat interrompu de la coque. Cette construction a pour but d'assurer une fixation optimale du pied à l'intérieur de la chaussure et en même temps une adaptation optimale au pied du skieur. Il n'a pas été tenu compte du fait que tous les appuis sur le ski se font par le côté intérieur de la chaussure, car dans cette construction l'appui interne a lieu sur une pièce rapportée donc peu rigide et la transmission des efforts au ski n'est pas optimale. En outre le serrage du pied se fait au moyen d'une boucle agissant sur la pièce auxiliaire, c'est-à-dire près du cou-de-pied. Avec les deux boucles du collier, on obtient une chaussure à trois boucles. Or, pour assurer une bonne tenue du pied, il est nécessaire d'avoir une quatrième boucle plus en avant sur le pied. Toutefois, en serrant le pied au moyen d'une quatrième boucle, on risque fort de créer un espace entre la coque et la pièce auxiliaire dans le cas où le serrage sur la pièce auxiliaire est plus faible que sur l'avant pied, ce qui est souvent le cas, car, près du cou-de-pied, il convient de laisser au tendon du pied un certain jeu pour se dilater. Le jeu créé à pour effet de supprimer l'étanchéité de la chaussure d'où, finalement, la nécessité de renoncer à la quatrième boucle.From document EP-A-0 353 532, a shoe of this type is known, in which the added auxiliary piece consists of a flap fixed laterally to the shell at one or two points and coming, on the one hand, covering the instep with the flap of the shell extending above the instep and, on the other hand, covering the transverse edge of the interrupted flap of the shell. The purpose of this construction is to ensure optimal fixation of the foot inside the boot and at the same time optimal adaptation to the skier's foot. It was not taken into account that all the supports on the ski are made by the interior side of the boot, because in this construction the internal support takes place on an insert therefore not very rigid and the transmission of forces to skiing is not optimal. In addition, the tightening of the foot is done by means of a loop acting on the auxiliary part, that is to say near the instep. With the two loops of the necklace, we obtain a shoe with three loops. However, to ensure a good hold of the foot, it is necessary to have a fourth loop further forward on the foot. However, by tightening the foot with a fourth loop, there is a strong risk of create a space between the shell and the auxiliary part in the case where the clamping on the auxiliary part is weaker than on the forefoot, which is often the case, because, near the instep, it is advisable to leave some clearance in the tendon of the foot to expand. The game created has the effect of removing the waterproofness of the shoe, hence, ultimately, the need to give up the fourth loop.

De la demande de brevet italien N° 22791B/73, on connaît par ailleurs une chaussure dont la coque présente deux fentes s'étendant parallèlement de chaque côté du pied et définissant une languette recouvrant le pied et le cou-de-pied, cette languette étant recouverte partiellement par un manchon fendu entourant la coque et recouvrant les fentes. La languette étendue facilite le chaussage, mais les fentes réduisent fortement la rigidité de la coque de chaque côté de celle-ci et partant sa capacité de transmettre les efforts au ski.From Italian patent application No. 22791B / 73, a shoe is also known whose shell has two slots extending parallel to each side of the foot and defining a tongue covering the foot and the instep, this tongue being partially covered by a split sleeve surrounding the shell and covering the slots. The extended tongue makes it easier to put on, but the slots greatly reduce the rigidity of the shell on each side of it and hence its ability to transmit forces to the ski.

Du document FR-A-2 498 431, on connaît d'autre part une chaussure en matière plastique dont le coque présente une ouverture disposée le long du cou-de-pied destinée à permettre l'introduction du pied dans la coque, cette ouverture étant recouverte par une langue articulée sur l'avant de la coque. Cette construction n'est toutefois pas utilisable avec une tige en forme de collier, mais avec une tige en deux parties en forme de gouttière.From document FR-A-2 498 431, a plastic shoe is also known, the shell of which has an opening disposed along the instep intended to allow the introduction of the foot into the shell, this opening being covered by a tongue articulated on the front of the hull. However, this construction cannot be used with a collar-shaped rod, but with a two-part rod in the form of a gutter.

La présente invention a pour but de réaliser une chaussure à coque à volume variable et tige en forme de collier dont le chaussage est facilité sans risque de perte d'étanchéité et assurant une transmission optimale des efforts de la jambe au ski.The object of the present invention is to produce a shoe with a variable volume shell and a collar-shaped upper, the boot of which is facilitated without risk of loss of tightness and ensuring optimum transmission of the forces from the leg to the ski.

La chaussure selon l'invention est caractérisée en ce que le rabat de la coque s'étendant jusqu'au-dessus du cou-de-pied est le rabat du côté intérieur de la chaussure et que ladite pièce auxiliaire rapportée est solidaire d'une pièce de recouvrement de la zone métatarsophalangienne.The shoe according to the invention is characterized in that the flap of the shell extending to above the instep is the flap on the inside of the shoe and that said added auxiliary part is secured to a covering piece of the metatarsophalangeal zone.

La transmission des efforts de la jambe du côté interne de la chaussure pour assurer la prise de carre s'effectue directement sur la coque elle-même et elle est donc beaucoup plus efficace.The transmission of the efforts of the leg from the internal side of the shoe to ensure the edge grip takes place directly on the shell itself and it is therefore much more effective.

D'autre part, une continuité étant assurée entre la pièce de recouvrement de la zone métatarsienne et la pièce auxiliaire, un serrage différencié en deux points de la pièce de recouvrement n'a aucun effet négatif sur l'étanchéité.On the other hand, since continuity is ensured between the covering part of the metatarsal zone and the auxiliary part, differentiated tightening at two points of the covering part has no negative effect on the seal.

En outre, il s'avère que la libération du côté extérieur de la chaussure facilite davantage l'introduction du pied dans la chaussure que la libération du côté intérieur.In addition, it turns out that the release from the outside of the shoe makes it easier to introduce the foot into the shoe than the release from the inside.

La pièce de recouvrement peut être soit enveloppante, en forme de bande entourant la coque sur un peu plus de 360° en position fermée et serrée, soit en forme de capot maintenu par des câbles de serrage.The covering part can be either enveloping, in the form of a band surrounding the shell over a little more than 360 ° in the closed and tight position, or in the form of a hood maintained by clamping cables.

La pièce auxiliaire peut être venue d'une pièce d'injection avec la pièce de recouvrement ou bien rapportée, par exemple par soudage à ultrasons ou surmoulage. Dans ce cas, la pièce auxilaire peut avantageusement présenter une résistance et une dureté différentes de la pièce de recouvrement. La pièce de recouvrement peut ainsi être réalisée en matériau relativement rigide, par exemple en polyuréthane chargé avec du KEVLAR (marque déposée), tandis que la pièce auxiliaire est réalisée en un matériau plus souple pour faciliter le chaussage. Une telle structure peut également être obtenue par la technique de bi-injection.The auxiliary part may have come from an injection part with the covering part or else added, for example by ultrasonic welding or overmolding. In this case, the auxiliary part can advantageously have a resistance and a hardness different from the covering part. The covering part can thus be made of relatively rigid material, for example in polyurethane loaded with KEVLAR (registered trademark), while the auxiliary part is made of a more flexible material to facilitate fitting. Such a structure can also be obtained by the bi-injection technique.

Le dessin annexé représente, à titre d'exemple, quelques formes d'exécution de l'invention.The accompanying drawing shows, by way of example, some embodiments of the invention.

La figure 6 représente une deuxième forme d'exécution d'une chaussure complète sans les boucles et levier-tendeur.Figure 6 shows a second embodiment of a complete shoe without the buckles and tensioner lever.

La figure 7 est une vue éclatée, analogue à la figure 1, d'une troisième forme d'exécution.Figure 7 is an exploded view, similar to Figure 1, of a third embodiment.

La figure 8 est une vue analogue d'une quatrième forme d'exécution.Figure 8 is a similar view of a fourth embodiment.

La figure 9 est un détail de la figure 8.Figure 9 is a detail of Figure 8.

La figure 1 représente une coque 1, par exemple en polyuréthane, comprenant la semelle et entourant le pied et le talon. Cette coque est à volume variable, c'est-à-dire qu'elle peut s'ouvrir selon une ligne longitudinale sur le pied, cette ouverture étant obtenue par deux rabats 2 et 3. Le rabat 2 s'arrête un peu au-dessus de la malléole, tandis que le rabat 3 s'étend sur et au-dessus du cou-de-pied par une partie 3a qui enveloppe partiellement le côté intérieur de la cheville. A l'arrière, la coque 1 est munie d'une languette 4 venant recouvrir le tendon d'Achille.FIG. 1 represents a shell 1, for example made of polyurethane, comprising the sole and surrounding the foot and the heel. This shell is of variable volume, that is to say that it can open along a longitudinal line on the foot, this opening being obtained by two flaps 2 and 3. The flap 2 stops a little above the malleolus, while the flap 3 extends over and above the instep by a part 3a which partially envelops the inner side of the ankle. At the rear, the shell 1 is provided with a tongue 4 which covers the Achilles tendon.

La coque est complétée par une pièce de recouvrement 5 en forme de collier, le côté extérieur de ce collier étant prolongé par une pièce auxiliaire 6 de forme galbée et s'étendant vers le haut et vers l'arrière et de forme à peu près symétrique à celle de la partie 3a.The shell is completed by a covering part 5 in the form of a collar, the outer side of this collar being extended by an auxiliary part 6 of curved shape and extending upwards and backwards and of roughly symmetrical shape. to that of part 3a.

Comme représenté à la figure 2, la pièce de recouvrement 5 vient entourer la coque 1 dans la région métatarsophalangienne, ses extrémités formant deux rabats 5a et 5b qui viennent se superposer de la même manière que les rabats 2 et 3 de la coque. La partie auxiliaire 6 vient recouvrir la partie laissée libre par le rabat 2 au-dessus de la malléole en remplaçant ainsi la partie manquante du rabat 2. La partie auxiliaire 6 est reliée à la pièce de recouvrement 5 par une partie relativement étroite facilitant la flexion de la partie 6 dans cette zone.As shown in Figure 2, the cover 5 surrounds the shell 1 in the metatarsophalangeal region, its ends forming two flaps 5a and 5b which are superimposed in the same way as the flaps 2 and 3 of the shell. The auxiliary part 6 covers the part left free by the flap 2 above the malleolus, thus replacing the missing part of the flap 2. The auxiliary part 6 is connected to the covering part 5 by a relatively narrow part facilitating bending from Part 6 in this area.

Lors de l'introduction du pied dans la chaussure, la partie auxiliaire 6 s'écarte ainsi aisément, facilitant l'introduction du pied dans la coque.During the introduction of the foot into the shoe, the auxiliary part 6 thus deviates easily, facilitating the introduction of the foot into the shell.

Le serrage de la partie métatarsienne de la coque se fait par le serrage de la partie de recouvrement 5, de la même manière que le serrage d'une coque conventionnelle à volume variable. Les boucles de serrage sont fixées sur la pièce de recouvrement 5, de telle sorte qu'il n'est nécessaire de faire aucun trou dans la coque elle-même, et que celle-ci présente par conséquent une continuité avantageuse et une plus grande résistance. La coque peut être également allégée.The tightening of the metatarsal part of the hull is done by the tightening of the covering part 5, in the same way as the tightening of a conventional hull with variable volume. The tightening loops are fixed on the covering part 5, so that it is not necessary to make any hole in the shell itself, and that the latter consequently has advantageous continuity and greater resistance. . The hull can also be lightened.

La réparation de la chaussure en cas de déchirement ou d'arrachement dans la bouclerie peut se faire en changeant simplement la partie 5, la coque elle-même n'étant pas concernée.The repair of the shoe in the event of tearing or tearing in the buckles can be done by simply changing part 5, the shell itself not being concerned.

La coque 1 et la pièce de recouvrement 5 peuvent également être assemblées comme représenté à la figure 3. Dans ce cas, le rabat 5b de la pièce de recouvrement 5 est pris entre le rabat inférieur 2 et le rabat supérieur 3 de la coque et la pièce auxiliaire 6 vient à l'intérieur de la coque, sous la partie 3a. On constate immédiatement que cette solution présente une meilleure continuité entre la zone métatarsienne et le cou-de-pied. Le comportement en flexion de la chaussure au niveau du cou-de-pied est donc meilleur, ainsi que l'étanchéité.The shell 1 and the covering part 5 can also be assembled as shown in FIG. 3. In this case, the flap 5b of the covering part 5 is taken between the lower flap 2 and the upper flap 3 of the shell and the auxiliary part 6 comes inside the hull, under part 3a. We immediately see that this solution has better continuity between the metatarsal area and the instep. The flexing behavior of the shoe at the instep is therefore better, as well as the waterproofness.

La chaussure, dont les éléments plastiques sont représentés en éclaté à la figure 4, utilise le mode d'exécution selon la figure 2. La coque est complétée par un collier 7 articulée sur la coque 1 et formant la tige de la chaussure. Ce collier 7 est échancré à l'arrière, l'échancrure étant fermée par un capot 8 également articulé sur la coque. Cette construction est décrite dans les brevets US 4 839 973 et EP 0 286 586.The shoe, the plastic elements of which are shown in exploded view in FIG. 4, uses the embodiment according to FIG. 2. The shell is completed by a collar 7 articulated on the shell 1 and forming the upper of the shoe. This collar 7 is scalloped at the rear, the scallop being closed by a cover 8 also articulated on the shell. This construction is described in US patents 4,839,973 and EP 0 286 586.

La figure 5 représente la même chaussure complète. On distingue la pièce de recouvrement 5 et le départ 6a de la pièce auxiliaire 6 recouverte ici par le collier 7 articulé en 9 sur la coque 1. Le capot 8 est articulé en 10 sur la coque. La partie métatarsienne du pied est serrée au moyen de deux boucles 11 et 12 fixées sur le côté extérieur de la pièce de recouvrement 5 et permettant d'exercer une traction sur deux câbles 13 et 14 ancrés dans le rabat 5a ou plus en arrière de celui-ci. Le collier 7 est fermé et serré de manière connue au moyen de deux boucles 15 et 16.Figure 5 shows the same complete shoe. There are the covering part 5 and the start 6a of the auxiliary part 6 covered here by the collar 7 articulated at 9 on the hull 1. The cover 8 is articulated at 10 on the hull. The metatarsal part of the foot is tightened by means of two loops 11 and 12 fixed on the outside of the covering part 5 and making it possible to exert traction on two cables 13 and 14 anchored in the flap 5a or more behind that -this. The collar 7 is closed and tightened in a known manner by means of two loops 15 and 16.

On reconnaît en outre un chausson intérieur 10 et une sangle 18 pour assurer l'appui du tibia lors de la flexion.We also recognize an inner boot 10 and a strap 18 to ensure the support of the tibia during flexion.

La figure 6 représente une autre forme d'exécution dans laquelle la pièce de recouvrement est en forme de capot 20. Au capot 20 sont attachés des câbles tels que les câbles 21 et 22, eux-mêmes reliés à des dispositifs tendeurs pour le serrage de l'avant pied et du cou-de-pied. Les câbles peuvent également servir à la retenue du capot 20. Le câble 21 peut former une boucle sur l'autre côté du capot 20. Le câble 22 est ancré au capot 20 en un point 23 et il passe au-dessous du rivet d'articulation 10 de l'étrier 8 pour ressortir sensiblement verticalement sur le collier 7 par un passage 24 où il est attaché à un levier-tendeur non représenté fixé sur le collier.FIG. 6 represents another embodiment in which the covering part is in the form of a cover 20. To the cover 20 are attached cables such as cables 21 and 22, themselves connected to tensioning devices for tightening the forefoot and instep. The cables can also be used to retain the cover 20. The cable 21 can form a loop on the other side of the cover 20. The cable 22 is anchored to the cover 20 at a point 23 and it passes below the rivet. articulation 10 of the stirrup 8 to come out substantially vertically on the collar 7 by a passage 24 where it is attached to a not shown tensioning lever fixed on the collar.

Une troisième forme d'exécution est représentée à la figure 7. Cette forme d'exécution diffère de la première forme d'exécution en ce que la coque 1 présente une découpe 25 sur le pied ne laissant subsister que des amorces de rabats 2 et 3 sauf sur le cou-de-pied en 26 et à leurs extrémités avant en 27 où ils se recouvrent comme dans la première forme d'exécution. La découpe 25 est recouverte par la pièce de recouvrement 5.A third embodiment is shown in Figure 7. This embodiment differs from the first embodiment in that the shell 1 has a cutout 25 on the foot leaving only primers for flaps 2 and 3 except on the instep at 26 and at their front ends at 27 where they overlap as in the first embodiment.
