Description

La présente invention a pour objet une chaussure de ski constituée d'une partie inférieure comprenant la semel­le et l'empeigne et entourant le talon et d'une tige, en une ou deux parties, articulée sur la partie infé­rieure en deux points opposés coïncidant au moins ap­proximativement avec l'articulation du pied de l'uti­lisateur.The present invention relates to a ski boot consisting of a lower part comprising the sole and the upper and surrounding the heel and of a rod, in one or two parts, articulated on the lower part at two opposite points coinciding with the less approximately with the user's foot joint.

Selon leur mode de chaussage on distingue essentiel­lement deux types de chaussures à coque en matière synsynthétique. Les chaussures du premier type, dites à chaussage par le haut, comprennent une tige en une seule pièce se fermant à l'avant, telle que décrite, par exemple dans le brevet CH 549.970. Les chaussures du deuxième type, dites à chaussage par l'arrière, com­prennent une tige formée d'une partie avant et d'une partie arrière venant s'emboîter dans la partie avant pour entourer le pied du skieur et rabattable en arriè­re pour le chaussage, telle que décrite, par exemple, dans le brevet FR 2.428.413.According to their fitting method, there are essentially two types of shell shoes made of synsynthetic material. Shoes of the first type, known as footwear from above, include a one-piece upper closing at the front, as described, for example in patent CH 549,970. Shoes of the second type, known as rear boot, include a rod formed by a front part and a rear part which fits into the front part to surround the skier's foot and can be folded back for the boot , as described, for example, in patent FR 2,428,413.

Dans les chaussures du premier type, comme ceci appa­raît clairement à la figure 2 du brevet CH 549.970, le basculement vers l'arrière de la tige autour de l'axe d'articulation passant par les malléoles, n'est pas possible, car la tige vient buter immédiatement contre l'arrière de la coque inférieure. Pour permettre un léger basculement en arrière il faudrait laisser un espace entre la tige et la coque inférieure, espace qui laisserait pénétrer la neige à l'intérieur de la coque. Un tel espace est donc inacceptable et il faut au contraire si possible assurer un contact permanent entre la tige et la coque inférieure.In shoes of the first type, as this clearly appears in FIG. 2 of patent CH 549,970, the rearward tilting of the upper around the articulation axis passing through the malleoli is not possible, because the rod abuts immediately against the rear of the lower shell. To allow a slight tilting backwards, a space should be left between the rod and the lower hull, a space which would allow snow to penetrate inside the hull. Such a space is therefore unacceptable and, on the contrary, if possible, ensure permanent contact between the rod and the lower shell.

Dans les chaussures du deuxième type, à chaussage par l'arrière, la partie arrière de la tige peut basculer en arrière, car son axe d'articulation, confondu avec l'axe d'articulation de la tige est situé en-dessous de l'articulation du pied du skieur. Une telle articu­lation de la tige n'est toutefois pas adéquate lors de la pratique du ski car elle ne correspond pas à l'ar­ticulation naturelle du pied et engendre une pression sur le talon lors de la flexion vers l'avant. L'écart entre l'articulation de la tige de la chaussure et l'articulation du pied du skieur produit en outre, lors de la flexion de la jambe, une zone de contact linéaire autour de l'appui tibial de la jambe.In shoes of the second type, fitted with the rear, the rear part of the upper can tilt back, because its axis of articulation, coincident with the axis of articulation of the upper is located below the articulation of the skier's foot. Such an articulation of the upper, however, is not adequate when skiing since it does not correspond to the natural articulation of the foot and generates pressure on the heel during forward bending. The distance between the articulation of the upper of the shoe and the articulation of the skier's foot also produces, during the flexion of the leg, a zone of linear contact around the tibial support of the leg.

On a déjà proposé d'obvier à ces défauts en articulant la partie arrière de la tige sur sa partie avant et non sur la coque inférieure et en articulant la partie avant sur la coque autour d'une seconde articulation coïncident avec l'articulation du pied du skieur. En position fermée, la chaussure est alors équivalente à une chaussure du premier type avec le même inconvénient c'est-à-dire l'impossibilité de basculer en arrière, de telle sorte que même libérée, la tige ne permet pas une marche normale, avec ou sans ski. On a en outre proposé d'obvier au défaut de l'appui tibial dans une chaussure à chaussage par l'arrière en montant une plaque de répartition de la pression, articulée, dans la partie antérieure supérieure de la tige (FR-A-2506135).It has already been proposed to obviate these defects by articulating the rear part of the rod on its front part and not on the lower shell and by articulating the front part on the shell around a second articulation coinciding with the articulation of the foot. of the skier. In the closed position, the shoe is then equivalent to a shoe of the first type with the same drawback, that is to say the impossibility of tilting backwards, so that even when released, the upper does not allow normal walking, with or without ski. It has also been proposed to obviate the defect of the tibial support in a shoe fitted with the rear by mounting a pressure distribution plate, articulated, in the upper front part of the upper (FR-A-2506135 ).

L'invention a pour but de permettre à la tige de la chaussure non seulement de se redresser en position libre, mais également de basculer en arrière d'un angle relativement important, tout en étant articulée autour d'un axe coïncidant avec l'articulation du pied du skieur.The invention aims to allow the upper of the shoe not only to straighten in the free position, but also to tilt backward at a relatively large angle, while being articulated around an axis coinciding with the joint. of the skier's foot.

Ceci a deux avantages : le premier, pour une chaussure du premier type, de faciliter le chaussage en rabattant au maximum la tige en une pièce vers l'arrière, de telle sorte que la chaussure à chaussage par le haut devient pratiquement une chaussure à chaussage par l'arrière; le deuxième de faciliter la marche au moyen des deux types de chaussure, notamment à la descente, en permettant à la tige de suivre le pivotement naturel du pied.This has two advantages: the first, for a shoe of the first type, to facilitate the fitting by folding the upper in one piece to the rear as much as possible, so that the shoe fitting from above becomes practically a shoe fitting rear; the second to facilitate walking by means of the two types of shoe, in particular when descending, by allowing the upper to follow the natural pivoting of the foot.

Ce but est atteint par la chaussure selon l'invention, telle que définie par la revendication 1.This object is achieved by the shoe according to the invention, as defined by claim 1.

Selon une forme d'exécution la région découverte par l'échancrure est recouverte par un capot en forme d'étrier articulé sur la partie inférieure de la chaus­sure en deux points opposés situés en dessous des points d'articulation de la tige de telle sorte que ce capot peut basculer en arrière, la partie postérieure de la tige et le capot basculant étant reliés entre eux par un organe de liaison rigide s'étendant dans un plan vertical et dont les extrémités sont articulées respec­tivement sur la tige et sur le capot basculant.According to one embodiment, the region discovered by the notch is covered by a stirrup-shaped cover articulated on the lower part of the shoe at two opposite points located below the points of articulation of the upper so that this cover can tilt back, the rear part of the rod and the tilting hood being connected together by a rigid connecting member extending in a vertical plane and the ends of which are articulated respectively on the rod and on the tilting hood.

Il est en outre sans autre possible de prévoir des moyens de verrouillage du capot du type décrit dans le brevet EP 0 086 908 pour verrouiller le capot sur la chaussure en position avancée de la tige et de prévoir un organe de liaison de longueur réglable permettant de régler l'inclinaison de la tige, comme défini dans les revendications dépendantes.It is furthermore without other possibility to provide means for locking the cover of the type described in patent EP 0 086 908 to lock the cover on the shoe in the advanced position of the upper and to provide a connecting member of adjustable length making it possible to adjust the inclination of the rod, as defined in the dependent claims.

Le capot basculant peut en outre être avantageusement utilisé pour l'attache de l'extrémité de câbles de traction destinés au serrage de la partie avant de la chaussure.The tilting cover can also be advantageously used for attaching the end of cables of traction for tightening the front part of the shoe.

La chaussure représentée au dessin est en matière syn­thétique moulée semi-rigide. Elle est constituée d'une partie inférieure 1 comprenant la semelle 2, l'empeigne 3 et une partie postérieure entourant le talon et pro­longée au-dessus du talon sous la forme d'une demi-tige, mieux visible à la figure 3. L'empeigne 3 présente deux oreilles superposées permettant le serrage du pied au moyen de deux câbles de traction 5 et 6. Sur cette par­tie inférieure 1 est articulée une tige 7 autour de deux rivets opposés 8 et 9 (figure 3) situés de telle sorte qu'ils soient en face de l'articulation naturelle du pied, c'est-à-dire de la malléole. Dans l'exemple d'exécution considéré, la tige 7 est en une partie, mais elle pourrait être également constituée de deux parties, soit une partie antérieure à une partie posté­rieure. La tige 7 se ferme à l'avant au moyen d'un ra­bat et de deux boucles 10 et 11 venant s'accrocher sur des leviers tendeurs 12 et 13. La chaussure comporte en outre un chausson intérieur 14 représenté uniquement à la figure 1. A son bord postérieur inférieur, la tige 7 présente une large échancrure arrondie 15 qui s'étend approximativement entre ses deux points d'articulation 8 et 9. Comme on le verra plus loin, cette échancrure 15 permet à la tige 7 de basculer très loin en arrière, contrairement aux tiges de ce type connues dont le bord antérieur inférieur vient très vite buter contre la partie inférieure de la chaussure. En position fermée de la chaussure, telle que représentée à la figure 1, cette échancrure 15 est recouverte par un capot 16 en forme d'étrier articulé sur la partie inférieure 1 de la chaussure, de chaque côté de celle-ci, en deux points opposés 17 et 18 situés en-dessous de la tige 7, au moyen de rivets, comme la tige 7. Ce capot 16 est relié à la tige 7 par un organe de liaison rigide 19 articulé par ses extrémités sur chacune des parties 7 et 16. Cet organe de liaison 19 est constitué par une tige métallique présentant deux parties filetées à pas opposés 20 et 21 s'étendant de chaque côté d'un poulet moleté 22 et se vissant dans deux cylindres 23 et 24 articulés respectivement sur la tige 7 et sur le capot 16. Au moyen du poulet moleté 22 il est donc possible de modifier la longueur de l'organe de liaison 19 et par conséquent l'inclinaison de la tige 7 relativement à celle du capot 16. Le capot 16 présente en outre un organe de verrouillage constitué par une bascule 25 articulée dans une échancrure du capot 16, autour d'un axe 26 et dont l'extrémité du bras inférieur 27 vient buter contre une butée constituée par une portée 28 formée sur la partie inférieure de la chaussure, en empêchant ainsi le capot 16 de basculer en arrière, c'est-à-dire en maintenant la tige 7 en position avan­cée pour la pratique du ski. La bascule 25 est mainte­nue dans cette position par un ressort 29 (figure 3) travaillant en compression entre le bras supérieur de la bascule 25 et le fond d'un logement formé dans le capot 16. La bascule 25 présente un creux visible à la figure 3 pour l'actionnement par un bâton de ski.The shoe shown in the drawing is made of semi-rigid molded synthetic material. It consists of a lower part 1 comprising the sole 2, the upper 3 and a rear part surrounding the heel and extended above the heel in the form of a half-upper, better visible in FIG. 3. L 'upper 3 has two superimposed ears allowing the clamping of the foot by means of two traction cables 5 and 6. On this lower part 1 is articulated a rod 7 around two opposite rivets 8 and 9 (Figure 3) located such so that they are in front of the natural articulation of the foot, i.e. the malleolus. In the embodiment considered, the rod 7 is in one part, but it could also be made up of two parts, either an anterior part to a posterior part. The upper 7 closes at the front by means of a flap and two loops 10 and 11 which hook onto tensioning levers 12 and 13. The shoe also includes an inner boot 14 shown only in FIG. 1. At its lower posterior edge, the rod 7 has a large rounded notch 15 which extends approximately between its two points of articulation 8 and 9. As will be seen later, this notch 15 allows the rod 7 to tilt very far behind, unlike uppers of this type known whose lower front edge abuts very quickly against the lower part of the shoe. In the closed position of the shoe, as shown in Figure 1, this notch 15 is covered by a cover 16 in the form of a stirrup articulated on the lower part 1 of the shoe, on each side thereof, at two points opposite 17 and 18 located below the rod 7, by means of rivets, like the rod 7. This cover 16 is connected to the rod 7 by a rigid connecting member 19 articulated by its ends on each of the parts 7 and 16 This connecting member 19 is constituted by a metal rod having two threaded parts with opposite pitches 20 and 21 extending on each side of a knurled chicken 22 and screwing into two cylinders 23 and 24 articulated respectively on the rod 7 and on the cover 16. By means of the knurled chicken 22 it is therefore possible to modify the length of the connecting member 19 and consequently the inclination of the rod 7 relative to that of the cover 16. The cover 16 also has a locking member constituted by a rocker 25 articulated in a notch of the cover 16, about an axis 26 and the end of the lower arm 27 of which abuts against a stop constituted by a bearing 28 formed on the lower part of the shoe, thereby preventing the cover 16 from tilting backward, that is to say by maintaining the rod 7 in the advanced position for skiing. The rocker 25 is held in this position by a spring 29 (Figure 3) working in compression between the upper arm of the rocker 25 and the bottom of a housing formed in the cover 16. The rocker 25 has a hollow visible in the figure 3 for actuation by a ski pole.

Lorsque le skieur désire se relaxer ou marcher, il lui suffit de déverrouiller le capot 16 en appuyant sur la bascule 25, ce qui lui permet de redresser la jambe. La tige 7, ainsi libérée, peut pivoter autour de son articulation. Par contre, dès que l'utilisateur se remet en position avancée pour skier, le capot 16 et la tige 7 se verrouillent automatiquement dès que le bord inférieur de la bascule 25 dépasse la portée 28.When the skier wants to relax or walk, he just has to unlock the hood 16 by pressing the rocker 25, which allows him to straighten the leg. The rod 7, thus released, can pivot around its articulation. On the other hand, as soon as the user returns to the advanced position for skiing, the cover 16 and the rod 7 are automatically locked as soon as the lower edge of the lever 25 exceeds the range 28.

Lors du déchaussage, après décrochage des boucles 10 et 11, la tige 7 peut basculer largement en arrière avec le capot 16, ce dernier pouvant basculer jusqu'à la semelle en raison de la position de ses points d'arti­culation 17 et 18 situés bien en dessous des points d'articulation de la tige 7. Il convient de souligner que l'articulation non anatomique du capot 16 n'a pas d'influence sur le mouvement de la tige 7, laquelle est par contre adaptée à l'anatomie du pied.During heaving, after loosening of the loops 10 and 11, the rod 7 can tilt far back with the cover 16, the latter being able to tilt up to the sole due to the position of its articulation points 17 and 18 located well below the articulation points of the rod 7. It should be emphasized that the non-anatomical articulation of the cover 16 has no influence on the movement of the rod 7, which on the other hand is adapted to the anatomy of the foot.

Les câbles 5 et 6, servant au serrage du pied, sont guidés dans des passages de la semelle et sont reliés au capot basculant 16 sur des portées duquel viennent s'appuyer des écrous moletés 30 et 31 permettant de régler la longueur active des câbles 5 et 6. Ainsi, le pied est automatiquement serré lorsque le skieur flé­chit la jambe vers l'avant et que le capot basculant 16 vient se verrouiller sur la partie inférieure de la chaussure. Inversement, lors de l'ouverture de la chaussure (figure 2), la tension sur les câbles 5 et 6 est largement relâchée, ce relâchement étant égal à la hauteur de basculement du capot 16.The cables 5 and 6, used for tightening the foot, are guided in passages of the sole and are connected to the tilting cover 16 on spans from which come use knurled nuts 30 and 31 to adjust the active length of cables 5 and 6. Thus, the foot is automatically tightened when the skier bends the leg forward and the tilting hood 16 is locked on the part bottom of the shoe. Conversely, during the opening of the boot (FIG. 2), the tension on the cables 5 and 6 is largely relaxed, this relaxation being equal to the tilting height of the cover 16.

Comme cela à déjà été mentionné plus haut, la partie inférieure 1 de la chaussure présente une demi-tige dont la partie postérieure 32 est séparée de la partie antérieure 33 par deux échancrures latérales 34 se pro­longeant obliquement dans la partie postérieure 32 par deux fentes obliques opposées 35 débouchant chacune dans deux découpes oblongues 36 s'étendant parallèle­ment le long du dos de la chaussure. Dans la zone 37 située à la hauteur des découpes 36, le dos de la chaussure présente dès lors une certaine souplesse per­mettant à la partie postérieure 32 de la demi-tige de fléchir en arrière, comme représenté à la figure 4, lorsque la chaussure est en position ouverte. Ce bascu­lement peut se faire soit sous la pression de la che­ville, soit par entraînement par la tige 7. Dans ce cas on prévoira une liaison à glissière entre la tige 7 et la partie 32.As already mentioned above, the lower part 1 of the shoe has a half-upper, the rear part 32 of which is separated from the front part 33 by two lateral notches 34 extending obliquely in the rear part 32 by two oblique slots opposite 35 each opening into two oblong cutouts 36 extending parallel along the back of the shoe. In the zone 37 located at the height of the cutouts 36, the back of the shoe therefore has a certain flexibility allowing the rear part 32 of the half-rod to flex backwards, as shown in FIG. 4, when the shoe is in the open position. This tilting can be done either under the pressure of the ankle, or by driving through the rod 7. In this case, a sliding connection will be provided between the rod 7 and the part 32.

Aux figures 3 et 4, le passage des câbles 5 et 6 à l'arrière de la chaussure est exécuté de façon un peu différente de celle représentée aux figures 1 et 2; les câbles ne s'étendent plus verticalement depuis le capot basculant 16 mais obliquement, ce qui réduit la lon­gueur de relaxation des câbles, mais réduit également fortement la courbure du câble au point de changement de direction et par conséquent les fottements.In FIGS. 3 and 4, the passage of the cables 5 and 6 at the rear of the shoe is carried out in a slightly different manner from that shown in FIGS. 1 and 2; the cables no longer extend vertically from the tilting cover 16 but obliquely, which reduces the relaxation length of the cables, but also greatly reduces the curvature of the cable at the point of change of direction and consequently the friction.

Il ressort particulièrement bien de la figure 4 que la chaussure peut être largement ouverte pour le chaussage et le déchaussage. Malgré l'échancrure 15 de la tige, l'étanchéité de la chaussure est assurée par la demi-­tige 32 et le capot basculant 16 qui vient non seule­ment recouvrir l'échancrure 15, mais également les fen­tes 35 dans leur partie inférieure.It is particularly clear from FIG. 4 that the shoe can be wide open for putting on and taking off. Despite the notch 15 of the upper, the tightness of the shoe is ensured by the half-upper 32 and the tilting cover 16 which not only covers the notch 15, but also the slots 35 in their lower part.

Les moyens selon l'invention sont bien entendu égale­ment applicables à une chaussure à bas de coque rigide comprenant des moyens de serrage diagonal du talon com­prenant un élément répartiteur de pression situé dans la région du cou-de-pied, entre la coque et le chausson intérieur. Il est bien entendu que la tige échancrée peut être seule, sans le capot basculant.The means according to the invention are of course also applicable to a shoe with a rigid shell bottom comprising means for diagonally tightening the heel comprising a pressure-distributing element situated in the region of the instep, between the shell and the liner interior. It is understood that the scalloped rod can be alone, without the tilting cover.

Le chausson intérieur 14 est représenté seul aux fi­gures 5 et 6. Il est du même type que le chausson dé­crit dans les brevets US 3 977 098 et 4 523 392, avec des modifications spécifiques pour son utilisation dans une chaussure du type décrit plus haut. Ce chausson comprend une partie supérieure ou tige 40 articulée sur une partie inférieure 41 autour d'un axe 42. Cette par­tie supérieure 40 est munie d'une poche 43 ouverte vers le bas et dans laquelle est engagée la partie posté­rieure 32 de la demi-tige de la chaussure. Le bord su­périeur de cette partie 40 du chausson est muni d'une partie flexible 44 qui recouvrir le bord supérieur de la tige 7 de la chaussure de telle manière que le chausson 14 reste parfaitement solidaire de la tige 7 de la chaussure lorsque celle-ci est ouverte. La partie flexible 44 du chausson est en outre munie d'une at­tache 45 à fixation de type Velcro (marque déposée). La languette 46 du chausson est fixée de manière conven­tionnelle.The inner boot 14 is shown alone in Figures 5 and 6. It is of the same type as the boot described in US Patents 3,977,098 and 4,523,392, with specific modifications for its use in a shoe of the type described above. This boot includes an upper part or upper 40 articulated on a lower part 41 around an axis 42. This upper part 40 is provided with a pocket 43 open downward and in which is engaged the rear part 32 of the half shoe upper. The upper edge of this part 40 of the liner is provided with a flexible part 44 which covers the upper edge of the upper 7 of the shoe so that the liner 14 remains perfectly integral with the upper 7 of the shoe when the latter is open. The flexible part 44 of the liner is further provided with a fastener 45 with Velcro type fastening (registered trademark). The tongue 46 of the liner is fixed in a conventional manner.
