Abstract

A ski boot with rear entry including a rigid shell integrally formed with a front part of an upper, opened towards the rear throughout its height and of a sort to be closed by a shield articulated on the boot in such a way as to be provided with at least two degrees of freedom, which permits every movement thereof, albeit limited, both in rotation and in translation in a substantially vertical plane, when the fastening means are in a closed position. It is possible, hence, to ensure the best possible fitting of the shield to the shape of the ankle and of the lower part of the calf. The shield may be articulated on the boot through its lower end in such a way as to permit play.

Description

La présente invention a pour objet une chaussure de ski à chaussage par l'arrière comprenant une coque rigide destinée à entourer le pied, le talon et la partie antérieure inférieure de la cheville, et une tige constituée d'une partie antérieure en forme de gouttière ouverte à l'arrière, solidaire de ladite coque, et d'une partie postérieure, en forme de gouttière, articulé sur la chaussure de manière à pouvoir pivoter autour d'un axe transversal à la chaussure et venant s'emboiter dans ladite partie antérieure pour former une manchette destinée à entourer la cheville, et des moyens de fixation de ladite manchette en position fermée.The present invention relates to a ski boot with rear boot comprising a rigid shell intended to surround the foot, the heel and the lower front part of the ankle, and a rod consisting of a front part in the shape of a gutter. open at the rear, integral with said shell, and with a rear part, in the form of a gutter, articulated on the shoe so as to be able to pivot around an axis transverse to the shoe and fitting into said anterior part to form a cuff intended to surround the ankle, and means for fixing said cuff in the closed position.

Plusieurs exécutions de ce type de chaussures ont été proposées à ce jour. Elles ont toutes en commun une articulation de la partie postérieure de la manchette par son extrémité inférieure, sur la coque, autour d'un axe fixe. Dans le brevet FR 2 428 413 la partie postérieure de la manchette, appelée capot arrière, est articulée sur la coque autour d'un axe fixe dans la zone des malléoles. C'est également le cas de la chaussure décrite dans la demande de brevet EP 0 053 340. On connaît également une chaussure monocoque dont la coque présente, sur sa partie postérieure, une large fente verticale s'étendant sur toute la hauteur de la coque et fermée par une languette articulée à la base de la coque par une patte venue d'une pièce avec cette languette (US-A-3 803 730). Cette forme d'articulation donne certes une certaine souplesse à la position de la languette, mais cette chaussure permet difficilement un véritable chaussage par l'arrière compte tenu de l'étroitesse de la fente de la coque. On a également proposé d'articuler la manchette dans la semelle par une partie souple reliée à une partie profilée (FR-A-2 358 119).Several versions of this type of shoe have been proposed to date. They all have in common an articulation of the rear part of the cuff by its lower end, on the shell, around a fixed axis. In patent FR 2 428 413 the rear part of the cuff, called the rear cover, is articulated on the shell around a fixed axis in the region of the malleoli. This is also the case of the shoe described in patent application EP 0 053 340. A monocoque shoe is also known, the shell of which has, on its rear part, a wide vertical slot extending over the entire height of the shell and closed by a tongue hinged to the base of the shell by a tab which comes in one piece with this tongue (US-A-3,803,730). This form of articulation certainly gives a certain flexibility to the position of the tongue, but this shoe hardly allows a real boot from the rear taking into account the narrowness of the slot of the shell. It has also been proposed to articulate the cuff in the sole by a flexible part connected to a profiled part (FR-A-2 358 119).

Compte tenu des points d'articulation du capot, respectivement de la languette, dans ces chaussures antérieures, une bonne adaptation, confortable, du capot à la jambe est difficile, car lorsqu'on ferme le capot et serre celui-ci contre la jambe, soit sa partie inférieure vient comprimer douloureusement le tendon d'Achille, soit il subsiste un espace entre cette partie inférieure et la cheville de telle sorte que la tenue du pied n'est pas suffisante et que la conduite du ski n'est pas parfaite. En outre, l'ouverture du capot par basculement en arrière est limitée par des raisons constructives et d'utilisations dans la neige, de telle sorte que l'on n'a pas véritablement un chaussage par l'arrière mais un chaussage facilité par le haut.Given the points of articulation of the hood, respectively of the tongue, in these anterior shoes, a good, comfortable adaptation of the hood to the leg is difficult, because when the hood is closed and it is pressed against the leg, either its lower part painfully compresses the Achilles tendon, or there remains a space between this lower part and the ankle so that the holding of the foot is not sufficient and the conduct of the ski is not perfect. In addition, the opening of the hood by tilting back is limited by constructive reasons and uses in the snow, so that there is not really a boot from the rear but a boot facilitated by the high.

La présente invention a principalement pour but d'obtenir une adaptation aussi bonne que possible de la partie postérieure articulée de la manchette à la jambe.The main object of the present invention is to obtain as good an adaptation as possible of the rear articulated part of the cuff to the leg.

A cet effet, la chaussure de ski selon l'invention est caractérisée par le fait que l'articulation de la partie postérieure de la tige sur la chaussure est telle qu'elle autorise en outre au moins un mouvement limité de translation en toutes directions de cette partie postérieure parallèlement au plan médian vertical de la chaussure en position fermé des moyens de fixation.To this end, the ski boot according to the invention is characterized in that the articulation of the rear part of the upper on the boot is such that it also allows at least a limited translational movement in all directions of this rear part parallel to the vertical median plane of the shoe in the closed position of the fastening means.

L'axe de pivotement n'occupe pas une position fixe, ni sur la partie postérieure articulée, ni relativement à la coque. Cette liberté de mouvement permet à la partie postérieure de la tige de s'adapter à la forme de la cheville et du mollet et de s'appuyer de façon quasi uniforme sur la jambe. Accessoirement ce mode d'articulation permet un dégagement total de la partie arrière de la chaussure, c'est-à-dire un authentique chaussage par l'arrière.The pivot axis does not occupy a fixed position, neither on the articulated rear part, nor relative to the hull. This freedom of movement allows the posterior part of the upper to adapt to the shape of the ankle and the calf and to rest almost uniformly on the leg. Incidentally, this mode of articulation allows total clearance of the rear part of the shoe, that is to say an authentic fitting from the rear.

La partie postérieure de la tige peut être articulée soit latéralement sur la partie antérieure par une liaison souple, soit par son extrémité inférieure par des moyens garantissant au moins deux degrés de liberté, tels qu'une biellette avec un jeu axial ou une articulation autour de deux pivots avec un jeu suffisant dans toutes les directions.The rear part of the rod can be articulated either laterally on the front part by a flexible connection, or by its lower end by means guaranteeing at least two degrees of freedom, such as a link with an axial play or an articulation around two pivots with sufficient play in all directions.

La chaussure représentée aux figures 1 à 6 est une chaussure du type monocoque, dont la coque en matière synthétique semi-rigide, par exemple en polyuréthane, est constituée d'une partie inférieure 1 entourant le pied et le talon et comprenant la semelle et d'une partie montante 2 constituant la partie antérieure de la tige de la chaussure. Cette partie 2 est en forme de gouttière ouverte à l'arrière et sur celle-ci est articulée une partie 3, de même matière que la coque 1, également en forme de gouttière, destinée à venir s'emboîter dans la partie antérieure 2 pour former une sorte de manchette destinée à entourer la cheville et la partie inférieure de la jambe. La partie postérieure 3 est articulée à la partie antérieure 2 au moyen de deux pattes latérales 4 et 5 traversant librement deux fentes verticales 6 et 7 ménagées dans une surépaisseur 8 de la partie 2 (fig. 5). La fixation de la partie 3 en position fermée est assurée par une sangle 9. Cette sangle 9 traverse une fente verticale 10 analogue aux fentes 6 et 7 et située entre celles-ci. Elle est retenue sur la partie 2 par un arrêt 11. Elle passe à travers un passant 12, approximativement au milieu de la partie postérieure 3 et elle est munie à son autre extrémité d'une boucle 13 coopérant avec un levier tendeur 14 articulé sur la partie 2. Pour empêcher un déplacement de la partie postérieure 3 le long de la sangle 9, celle-ci est fixée par un trou sur un téton 15 en métal rivé sur la partie 3. La sangle 9 présente plusieurs trous 16 permettant de régler la position relative de la sangle 9 de la partie 3.The shoe shown in Figures 1 to 6 is a shoe of the monocoque type, the shell of semi-rigid synthetic material, for example polyurethane, consists of a lower part 1 surrounding the foot and the heel and comprising the sole and d 'a rising part 2 constituting the front part of the upper of the shoe. This part 2 is in the form of a gutter open at the rear and on this is articulated a part 3, of the same material as the shell 1, also in the form of a gutter, intended to come to fit in the front part 2 for form a kind of cuff intended to surround the ankle and the lower part of the leg. The rear part 3 is articulated at the front part 2 by means of two lateral tabs 4 and 5 freely passing through two vertical slots 6 and 7 formed in an extra thickness 8 of part 2 (fig. 5). The fixing of the part 3 in the closed position is ensured by a strap 9. This strap 9 passes through a vertical slot 10 similar to the slots 6 and 7 and situated between them. It is retained on part 2 by a stop 11. It passes through a passer-by 12, approximately in the middle of the posterior part 3 and it is provided at its other end with a loop 13 cooperating with a tensioning lever 14 articulated on the part 2. To prevent displacement of the rear part 3 along the strap 9, the latter is fixed by a hole on a stud 15 made of metal riveted on the part 3. The strap 9 has several holes 16 making it possible to adjust the relative position of strap 9 of part 3.

La chaussure comporte en outre un chausson intérieur, non représenté aux figures 1,4 et 5, mais visible aux figures 2 et 3, chausson qui comporte une partie fixe 17 entourant le pied et la cheville comme les parties 1 et 2 de la coque et une partie postérieure 18 rabattante vers l'arrière. Ce chausson est en matière compressible et comprend une enveloppe extérieure étanche. En position fermée, telle que représentée aux figures 2, 3 et 4 la partie postérieure 3 de la tige vient s'emboîter dans la partie antérieure 2 et s'appuyer sur la partie 18 du chausson. Dans cette position la partie 3 peut se déplacer légèrement quasiment en tout sens, c'est-à-dire également autour d'un axe parallèle à la direction du pied, en raison de la souplesse des pattes 4 et 5, pour venir s'adapter à la forme de la jambe. Dans ce mouvement d'adaptation, les pattelettes 4 et 5 coulissent dans les fentes 6 et 7.The shoe also has an inner boot, not shown in FIGS. 1, 4 and 5, but visible in FIGS. 2 and 3, a boot which has a fixed part 17 surrounding the foot and the ankle like the parts 1 and 2 of the shell and a rear part 18 folding backwards. This liner is made of compressible material and includes a waterproof outer shell. In the closed position, as shown in Figures 2, 3 and 4, the rear part 3 of the upper fits into the front part 2 and rests on part 18 of the liner. In this position part 3 can move slightly almost in any direction, that is to say also around an axis parallel to the direction of the foot, due to the flexibility of the legs 4 and 5, to come adapt to the shape of the leg. In this adaptation movement, the flaps 4 and 5 slide in the slots 6 and 7.

Lorsque le skieur redresse la jambe ou la fléchit légèrement en arrière relativement à la plante du pied, la partie 3 a tendance à tourner sur elle-même dans le sens horaire à la figure 3. Pour limiter ce mouvement, qui aurait tendance à comprimer le tendon d'Achille par effet de levier, il est prévu une butée 19 sur la partie 3, butée qui vient buter contre le bord de la partie antérieure fixe 2.When the skier straightens the leg or bends it slightly back relative to the sole of the foot, part 3 tends to rotate clockwise in Figure 3. To limit this movement, which would tend to compress the Achilles tendon by leverage, there is a stop 19 on part 3, a stop which abuts against the edge of the fixed front part 2.

Dans des variantes d'exécution, la sangle de fixation pourrait être remplacée par tout autre disposition connu tel que les boucles utilisées couramment sur les chaussures de ski. Dans ce cas les pattes d'articulation 4 et 5 sont munies d'un arrêt analogue à l'arrêt 11 de la sangle.In alternative embodiments, the fastening strap could be replaced by any other known arrangement such as the buckles commonly used on ski boots. In this case, the articulation tabs 4 and 5 are provided with a stop similar to the stop 11 of the strap.

Une deuxième forme d'exécution est représentée aux figures 7 à 9. La chaussure est à nouveau constituée d'une coque 17 venue d'une pièce avec une partie antérieure 18 de la tige en forme de gouttière. La partie postérieure flottante 19 est ici articulée au talon de la coque 17 au moyen d'une biellette 20 a deux bras dont l'axe supérieur 21 est articulé dans une lumière 22 à la partie inférieure de la partie 19. La fermeture de la manchette formée des parties 18 et 19 est également assurée par une sangle 23 venue d'une pièce avec la partie antérieure 18 de la coque. Cette sangle est munie d'une boucle 24 coopérant avec un levier tendeur 25 analogue au levier 14. A l'intérieur de la coque 17 est monté un chausson intérieur 26 fendu du haut en bas de manière à présenter une partie arrière 27 sur laquelle s'appuie le capot 19 et susceptible d'être rabattue en arrière lorsque le capot 19 est ouvert. A l'endroit du passage de la sangle 23, le capot 19 présente une dépression 28 de section rectangulaire dans le fond de laquelle s'appuie la sangle 23 par une partie convexe 29 qui facilite la rotation du capot 19 dans le plan du dessin, comme indiqué par la flèche F1, en appui sur la partie convexe 29, mouvement autorisé par la biellette 20, la lumière 22 permettant en outre un déplacement en translation de haut en bas ou inversement, de telle sorte que le capot 19 peut prendre de lui-même la position la mieux adaptée à la jambe. L'articulation par la biellette 20 permet en outre de rabattre totalement le capot 19 en arrière, permettant ainsi un véritable chaussage par l'arrière.A second embodiment is shown in Figures 7 to 9. The shoe again consists of a shell 17 coming from one piece with a front part 18 of the rod in the form of a gutter. The floating rear part 19 is here articulated at the heel of the shell 17 by means of a link 20 with two arms whose upper axis 21 is articulated in a lumen 22 at the lower part of the part 19. The closure of the cuff formed of parts 18 and 19 is also provided by a strap 23 coming in one piece with the front part 18 of the shell. This strap is provided with a loop 24 cooperating with a tensioning lever 25 similar to the lever 14. Inside the shell 17 is mounted an inner liner 26 split from top to bottom so as to have a rear portion 27 on which s 'presses the cover 19 and can be folded back when the cover 19 is open. At the place of the passage of the strap 23, the cover 19 has a depression 28 of rectangular section in the bottom of which the strap 23 is supported by a convex part 29 which facilitates the rotation of the cover 19 in the plane of the drawing, as indicated by the arrow F1, pressing on the convex part 29, movement authorized by the link 20, the light 22 also allowing movement in translation from top to bottom or vice versa, so that the cover 19 can take it from itself - even the position best suited to the leg. The articulation by the link 20 also makes it possible to completely fold the cover 19 back, thus allowing true fitting from the rear.

Une troisième forme d'exécution est représentée aux figures 10 à 13. La coque est constituée des mêmes parties 17 et 18 que dans la forme d'exécution précédente. Cette chaussure est munie d'un capot arrière 30 qui ne diffère du capot 19 de l'exécution précédente que par son mode d'articulation à la coque 17. Cette articulation est ici constitué par deux pattes latérales 31 prolongeant le capot vers le bas de chaque côté du talon. L'extrémité coudée de ces pattes 31 est engagée dans un logement 32 formée entre la coque 17 et un flasque 33 solidaire de la coque. Ces extrémités présentent une lumière 34 traversée par un axe 35, les dimensions de la lumière 34 étant telles que l'articulation présente un jeu dans toutes les directions dans un plan perpendiculaire à l'axe 35 comme ceci est clairement visible à la figure 12. Le capot 30 comporte en outre, de chaque côté, une butée 36 venant buter sur les bords de la partie antérieure 18 pour limiter le basculement du capot 30 vers l'arrière. Ces butées 36 sont constituées par un plot amovible qui peut être fixé dans un autre trou 37 de manière à avoir une possibilité de réglage des butées. Pour le reste le capot et son dispositif de fixation sont identiques à ceux de la deuxième forme d'exécution, les mêmes parties étant désignées par les mêmes références. La chaussure comporte en outre un chausson intérieur en deux parties 26, 27 analogue à la forme d'exécution précédente. Pour l'ouverture de la chaussure le capot 30 est rabattu vers l'arrière autour des axes 35, comme représenté à la figure 13. Le jeu de l'articulation autour des axes 35, comme représenté à la figure 13, laisse une liberté suffisante au capot 30 pour s'adapter le mieux possible, naturellement, à la forme de la jambe.A third embodiment is shown in Figures 10 to 13. The shell consists of the same parts 17 and 18 as in the previous embodiment. This shoe is provided with a rear cover 30 which differs from the cover 19 of the previous embodiment only in its mode of articulation to the shell 17. This articulation is here constituted by two lateral tabs 31 extending the cover downwards. each side of the heel. The bent end of these legs 31 is engaged in a housing 32 formed between the shell 17 and a flange 33 secured to the shell. These ends have a light 34 crossed by an axis 35, the dimensions of the light 34 being such that the articulation has a play in all directions in a plane perpendicular to the axis 35 as this is clearly visible in FIG. 12. The cover 30 further comprises, on each side, a stop 36 abutting on the edges of the front part 18 to limit the tilting of the cover 30 towards the rear. These stops 36 are constituted by a removable stud which can be fixed in another hole 37 so as to have a possibility of adjusting the stops. For the rest, the cover and its fixing device are identical to those of the second embodiment, the same parts being designated by the same references. The shoe further comprises an inner liner in two parts 26, 27 similar to the previous embodiment. To open the boot, the cover 30 is folded back around the axes 35, as shown in FIG. 13. The play of the articulation around the axes 35, as represented in FIG. 13, leaves sufficient freedom. to the cover 30 to adapt as best as possible, naturally, to the shape of the leg.

Une quatrième form d'exécution représentée aux figures 14 à 16. La coque est à nouveau constituée des mêmes parties 17 et 18 que dans les formes d'exécution précédentes. Le capot flottant 38, constituant la partie postérieure de la manchette, est articulé ici à la partie antérieure 18 directement au moyen de la sangle 23 qui traverse un passant 39 au dos du capot 38. Ce capot peut être muni ou non d'un arrêt l'empêchant de coulisser librement le long de la sangle 23. La coque 17 abrite un chausson de confort 40 ouvert à l'arrière sur toute sa hauteur et fermé par une languette 41 en matière synthétique souple élastique injectée, par exemple en polyuréthane, cette languette 41 présentant une partie inférieure coudée et fixée par une vis 42 à une cale 43 occupant le fond de la chaussure ou directement à la coque. La vis 42 est recouverte par une semelle de confort 44. Immédiatement au-dessus de la partie de la coque 17 entourant le talon, la languette 41 présente un soufflet 45 donnant à cette partie la souplesse nécessaire à son adaptation àJa jambe et à son rabattement vers l'arrière (fig. 15) pour le chaussage. Le capot 38 vient prendre appui sur la languette 41 pour l'appliquer contre la jambe. Comme cela est visible à la figure 1, la sangle 23 traverse le passant 39 du capot avec un jeu horizontal et vertical qui permet au capot de se déplacer légèrement aussi bien en translation qu'en rotation. Pour le chaussage, le capot 38 peut être écarté totalement d'un côté et la languette entièrement rabattue, dégageant entièrement l'entrée du chausson 40, c'est-à-dire autorisant véritablement un chaussage par l'arrière.A fourth embodiment shown in Figures 14 to 16. The shell is again made of the same parts 17 and 18 as in the previous embodiments. The floating cover 38, constituting the rear part of the cuff, is hinged here to the front part 18 directly by means of the strap 23 which passes through a passer-by 39 on the back of the cover 38. This cover may or may not be provided with a stop preventing it from sliding freely along the strap 23. The shell 17 houses a comfort liner 40 open at the rear over its entire height and closed by a tongue 41 made of injected elastic flexible synthetic material, for example polyurethane, this tongue 41 having a bent lower part and fixed by a screw 42 to a wedge 43 occupying the bottom of the shoe or directly to the shell. The screw 42 is covered by a comfort sole 44. Immediately above the part of the shell 17 surrounding the heel, the tongue 41 has a bellows 45 giving this part the flexibility necessary for its adaptation to the leg and for its folding back (fig. 15) for putting on the shoes. . The cover 38 comes to bear on the tongue 41 to apply it against the leg. As can be seen in FIG. 1, the strap 23 crosses the passage 39 of the cover with a horizontal and vertical clearance which allows the cover to move slightly both in translation and in rotation. For the boot, the cover 38 can be moved completely to one side and the tongue fully folded down, completely freeing the inlet of the boot 40, that is to say truly authorizing a boot from the rear.

Toutes les formes d'exécution décrites pourraient comporter une partie avant de la manchette 2, respectivement 18 articulée sur la coque dans la région des malléoles.All the embodiments described could include a front part of the cuff 2, respectively 18 articulated on the shell in the region of the malleoli.
