Abstract

The boot is composed of a lower shell (1), on which an upper (2) is articulated about a pivot axis (5) coinciding at least approximately with the joint of the foot. The shell (1) has on the outside, at the rear, a rounded portion (12), the radius of curvature of which is centered on the pivot axis, (5), to allow the upper (2) to tilt to the rear. Means, such as ribs (17), are provided inside the part (11) of the shell in order to limit the space intended for receiving the skier's heel.

Description

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

Selon leur mode de chaussage on distingue essentiel­lement deux types de chaussures à coque en matière synthétique. 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 brevent FR-2.428.413.Depending on their fitting method, there are essentially two types of synthetic shell shoes. 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 brevent 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 tell 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. However, an articulation of the upper is not adequate when skiing since it does not correspond to the natural articulation of the foot and creates pressure on the heel when bending forward. 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 supérieure 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 upper 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 object of the invention is to allow the upper of the shoe not only to straighten in the free position, but also to tilt backwards at a relatively large angle, while being articulated around an axis coinciding with the articulation 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.

A cet effet la chaussure selon l'invention présente les caractéristiques défines à la revendication 1.To this end, the shoe according to the invention has the characteristics defined in claim 1.

Ce qui semblait impossible, en raison de la forme du pied et de la position de l'articulation de celui-ci, qui déterminent la forme de l'arrière de la coque de la chaussure, a été rendu possible en prolongeant la coque au-delà du profil déterminé par la forme du talon, c'est-à-dire, en quelque sorte, en trichant avec la forme naturelle qui semblait imposée.What seemed impossible, due to the shape of the foot and the position of the articulation thereof, which determine the shape of the rear of the shell of the shoe, was made possible by extending the shell to- beyond the profile determined by the shape of the heel, that is to say, in a way, by cheating with the natural shape that seemed imposed.

Un obstacle à cette mesure pouvait sembler être, dans le cas d'une chaussure en matière synthétique injectée, une surépaisseur importante de la coque dans la région du talon. Cet obstacle peut être écarté par des mesu­res adéquates, par exemple, en prévoyant à l'intérieur de la coque d'épaisseur habituelle, des nervures diri­gées vers l'avant et dont les bords limitent et défi­nissent l'espace prévu pour le talon du skieur ou par des alvéoles ou une double-paroi ou encore au moyen d'une pièce de remplissage rapportée .An obstacle to this measure could appear to be, in the case of a shoe of injected synthetic material, a significant excess thickness of the shell in the region of the heel. This obstacle can be removed by suitable measures, for example, by providing inside the hull of usual thickness, ribs directed forward and whose edges limit and define the space provided for the heel of the skier. or by cells or a double wall or by means of an attached filling part.

La chaussure représentée aux figures 1 à 3 comprend une coque 1 en matière synthétique moulée, cette coque 1 comprenant la semelle et l'empeigne de la chaussure et entourant le talon. Sur cette coque 1 est articulée une tige 2 en une pièce munie à l'avant de deux pattes 3 et 4 venant se rabattre l'une sur l'autre pour fermer la tige, cette position fermée étant maintenue par tous moyens adéquats, par exemple une boucle telle que re­présenté à la figure 8. La tige 2 entoure la partie supérieure de la coque 1, aussi bien à l'avant, au-­dessus du cou-de-pied, qu'à l'arrière autour du talon. La tige 2 est articulée sur la coque 1 autour d'un axe 5 correspondant au moins approximativement avec l'axe d'articulation du pied du skieur, au moyen de deux axes métalliques rivetés 6 et 7. L'intérieur de la chaus­sure comprend un chausson 8 et une cale 9 constituant un support plantaire donnant au pied une certaine inclinaison vers l'avant relativement à la semelle. Dans cette forme d'exécution, la partie supérieure antérieure 10 de la coque 1 monte relativement haut, de telle sorte que lorsque la tige est fermée et serrée, elle ne peut que très difficilement basculer en arrière.The shoe shown in Figures 1 to 3 comprises a shell 1 of molded synthetic material, this shell 1 comprising the sole and the upper of the shoe and surrounding the heel. On this shell 1 is articulated a rod 2 in one piece provided at the front with two legs 3 and 4 which fold over one another to close the rod, this closed position being maintained by any suitable means, for example a loop as shown in Figure 8. The rod 2 surrounds the upper part of the shell 1, both at the front, above the instep, and at the rear around the heel. The rod 2 is articulated on the shell 1 around an axis 5 corresponding at least approximately with the axis of articulation of the skier's foot, by means of two riveted metal axes 6 and 7. The interior of the boot comprises a liner 8 and a wedge 9 constituting a plantar support giving the foot a certain forward inclination relative to the sole. In this embodiment, the front upper part 10 of the shell 1 rises relatively high, so that when the rod is closed and tightened, it can only very easily tip back.

La partie arrière 11 de la coque entourant le talon présente extérieurement une surface 12 arrondie s'éten­dans sur la majeur partie de la hauteur de la coque et dont le rayon de courbure de la section verticale représenté à la figure 1 est centré sur l'axe 5 d'arti­culation de la tige 2. La tige 2, à ce même endroit du talon, présente également une surface intérieure 13 arrondie, dont la section verticale représentée à la figure 1 présente un rayon de courbure également centré sur l'axe d'articulation 5 et égal au rayon de courbure de la surface 12 de la coque. En outre, de part et d'autre du plan de coupe vertical de la figure 1, les surfaces 12 et 13 coïncident et sont jointives. La surface intérieure arrondie 13 est la continuité de la surface 12 de la coque au-dessus du talon et s'étend jusqu'au chausson où elle est raccordée à une surface quasiment cylindrique jointive avec le chausson 8. Dans cette zone, la rigidité de la tige est assurée par deux nervures verticales 15. On constate à la figure 1 que le talon 11 de la coque 1 ne correspond pas au talon 16 du chausson 8, c'est-à-dire à la position du talon du skieur, mais qu'il existe un espace relativement impor­tant entre le talon 16 du chausson et le talon 11 de la coque. Etant donné qu'il est essentiel que le talon du skieur soit bien maintenu en arrière dans la chaus­sure, cet espace doit être comblé. Dans la première forme d'exécution représentée aux figures 1 à 3, cet espace est occupé par deux nervures verticales 17 et 18 venues de moulage avec la coque et s'étendant vers l'avant, les bords antérieurs de ces nervures 17 et 18 définissant l'enveloppe de la surface d'appui du talon 16 du chausson.The rear part 11 of the shell surrounding the heel has an exterior rounded surface 12 extending over most of the height of the shell and the radius of curvature of the vertical section shown in Figure 1 is centered on the axis 5 of articulation of the rod 2. The rod 2, at this same location of the heel, also has a rounded inner surface 13, the vertical section of which shown in FIG. 1 has a radius of curvature also centered on the axis of articulation 5 and equal to the radius of curvature of the surface 12 of the shell. In addition, on either side of the vertical section plane of Figure 1, the surfaces 12 and 13 coincide and are contiguous. The rounded inner surface 13 is the continuity of the surface 12 of the shell above the heel and extends to the liner where it is connected to an almost cylindrical surface contiguous with the liner 8. In this zone, the rigidity of the upper is provided by two vertical ribs 15. It can be seen in FIG. 1 that the heel 11 of the shell 1 does not correspond to the heel 16 of the liner 8, that is to say the position of the heel of the skier, but that there is a relatively large space between the heel 16 of the liner and the heel 11 of the shell. Since it is essential that the skier's heel is well held back in the shoe, this space must be filled. In the first embodiment shown in Figures 1 to 3, this space is occupied by two vertical ribs 17 and 18 molded with the shell and extending forward, the front edges of these ribs 17 and 18 defining the envelope of the bearing surface of the heel 16 of the liner.

Lorsqu'on ouvre la chaussure en libérant l'une de l'au­tre les pattes 3 et 4 de la tige 2, comme représenté à la figure 3, on voit que la tige 2 peut basculer rela­tivement loin en arrière étant donné que la surface extérieure 12 de la coque et la surface intérieure 13 de la tige 2 coïncident. En outre, dans toutes les positions de la tige 2 relativement à la coque 1, les surfaces 12 et 13 sont jointives selon une surface de joint 14 relativement importante en toutes positions de la tige relativement à la coque, ce qui assure une bonne étanchéité de la chaussure. Dans la position extrême de basculement en arrière, représentée à la figure 3, la partie postérieure de la tige est prati­quement rabattue en arrière autant que dans une chaus­sure à chaussage par l'arrière de conception connue, alors que la chaussure représentée est conçue comme une chaussure à chaussage par le haut, ce qui a pour consé­quence de faciliter grandement le chaussage de la chaussure. Pour fermer la chaussure, il suffit de repousser la tige 2 vers l'avant et de fermer la boucle prévue sur cette tige. La chaussure peut bien entendu comporter des moyens de serrage additionels du pied, par exemple des moyens de serrage connus disposés à l'intérieur de la coque sur le cou-de-pied, entre le chausson et la coque.When the shoe is opened by releasing the legs 3 and 4 of the rod 2 from one another, as shown in FIG. 3, it can be seen that the rod 2 can tilt relatively far back since the external surface 12 of the shell and the inner surface 13 of the rod 2 coincide. In addition, in all the positions of the rod 2 relative to the shell 1, the surfaces 12 and 13 are contiguous according to a relatively large joint surface 14 in all positions of the rod relative to the shell, which ensures good sealing of the shoe. In the extreme rear tilting position shown in FIG. 3, the rear part of the upper is practically folded back as much as in a shoe with rear boot of known design, while the shoe shown is designed as a shoe with boot from the top, which has the consequence of greatly facilitating the fitting of the shoe. To close the shoe, simply push the rod 2 forward and close the loop provided on this rod. The shoe can of course include additional clamping means for the foot, for example known clamping means disposed inside the shell on the instep, between the liner and the shell.

D'autres moyens peuvent être prévus pour combler l'es­pace entre le talon 16 du chausson 8 et l'arrière 11 de la coque. Par exemple, comme représenté à la figure 4, le support plantaire 19, analogue au support plantaire 9, peut être muni d'une partie postérieure 20 s'éten­dant verticalement et présentant d'un côté une surface 21 épousant la surface intérieure de la partie 11 de la coque et, de l'autre côté, une surface 22 formant un logement adéquat pour le chausson 16, c'est-à-dire pour le talon du skieur.Other means can be provided to fill the space between the heel 16 of the liner 8 and the rear 11 of the shell. For example, as shown in FIG. 4, the plantar support 19, analogous to the plantar support 9, can be provided with a rear part 20 extending vertically and having on one side a surface 21 matching the internal surface of the part 11 of the hull and, on the other side, a surface 22 forming a adequate housing for the liner 16, that is to say for the heel of the skier.

Selon une autre forme d'exécution représentée à la figure 5, l'espace est occupé par une pièce rapportée 23, de préférence en matière plastique, fixée au moyen d'une vis 24 à la partie 11 de la coque 1.According to another embodiment shown in FIG. 5, the space is occupied by an insert 23, preferably made of plastic, fixed by means of a screw 24 to the part 11 of the shell 1.

Selon une autre forme d'exécution représentée aux fi­gures 6 et 7, des alvéoles 25, 26 et 27 sont formées lors du moulage dans une surépaisseur de la coque, de manière à laisser subsister une paroi intérieure 28. Cette structure est à la fois légère et rigide.According to another embodiment shown in Figures 6 and 7, cells 25, 26 and 27 are formed during molding in an extra thickness of the shell, so as to leave an inner wall 28. This structure is both light and rigid.

L'espace entre la paroi extérieure 11 de la coque 1 et le talon 16 du chausson, en particulier les nervures 17 et 18, ainsi que les nervures de renforcement 15 de la tige 2, peuvent être avantageusement utilisés pour monter un mécanisme de commande du basculement de la tige en arrière ou en avant et de verrouillage de la tige en position de fermeture lors de la pratique du ski. Un tel mécanisme est représenté aux figures 8 à 12. Ce mécanisme est un mécanisme à genouillère consti­tué d'un levier 29 articulé à son extrémité inférieure autour d'un axe 30 monté entre et dans les nervures 17 et 18 de la coque 1 et d'une biellette 31 articulée en un point intermédiaire du levier 29 au moyen d'un axe 32 monté entre deux joues 33 et 34 du levier 29 (figure 12) et, à son autre extrémité, entre et dans les deux nervures 15 de renforcement de la tige 2 au moyen d'un axe 35 susceptible de se déplacer dans des lumières 36 s'étendant dans le même sens que les nervures 15. Le levier 29 présente une extrémité d'actionnement 37 en forme de U comprenant les joues 33 et 34 et recouvrant l'articulation 32. Dans la position de verrouillage en position avancée de la tige, l'axe d'articulation 32 est situé entre la ligne droite joignant les axes 30 et 35 et la paroi de la tige 2. L'axe 35 est en appui, avec pression, contre l'extrémité supérieure des lumiè­res 36. Dans la position fermée, pour la pratique du ski, représentée aux figures 8 et 9, la tige est maintenue en position avancée par le mécanisme décrit. La tige est en outre fermée par une boucle convention­nelle 38 reliant la patte 4 au côté de la tige 2. Lors de la flexion de la jambe la tige 2 peut pivoter vers l'avant en raison de la lumière 36, calculée pour lais­ser un ébat suffisant à la flexion. La résistance élastique à la flexion vers l'avant peut être assurée par la matière même de la coque 1 et de la tige 2 ou par des moyens élastiques auxiliaires, sur le cou-de-­pied, entre la tige et la coque ou disposés dans la genouillère.The space between the outer wall 11 of the shell 1 and the heel 16 of the liner, in particular the ribs 17 and 18, as well as the reinforcing ribs 15 of the upper 2, can advantageously be used to mount a control mechanism for the tilting the rod backwards or forwards and locking the rod in the closed position when skiing. Such a mechanism is shown in Figures 8 to 12. This mechanism is a toggle mechanism consisting of a lever 29 articulated at its lower end about an axis 30 mounted between and in the ribs 17 and 18 of the shell 1 and d 'a link 31 articulated at an intermediate point of the lever 29 by means of a pin 32 mounted between two cheeks 33 and 34 of the lever 29 (Figure 12) and, at its other end, between and in the two ribs 15 of reinforcement of the rod 2 by means of an axis 35 capable of moving in slots 36 extending in the same direction as the ribs 15. The lever 29 has an actuating end 37 in the shape of a U comprising the cheeks 33 and 34 and covering the joint 32. In the locked position in advanced position of the rod, the articulation axis 32 is located between the straight line joining the axes 30 and 35 and the wall of the rod 2. The axis 35 presses against the upper end of the lights 36. In the closed position, for skiing, shown in Figures 8 and 9, the rod is held in the advanced position by the mechanism described. The rod is further closed by a conventional loop 38 connecting the tab 4 to the side of the rod 2. When bending the leg, the rod 2 can pivot forward due to the light 36, calculated to leave a frolic sufficient for bending. The elastic resistance to forward bending can be provided by the material of the shell 1 and the rod 2 or by auxiliary elastic means, on the instep, between the rod and the shell or arranged in the knee brace.

Lorsque le skieur désire déchausser sa chaussure, il tire sur l'extrémité 37 du levier 29 dans la direction de la flèche F1, figure 10. Compte tenu du non-aligne­ment des axes 30, 32 et 35, cette traction a tout d'abord tendance à écarter l'un de l'autre les axes 30 et 35. Si la boucle 38 est encore fermée et tendue, l'utilisateur rencontre une certain résistance, mais l'élasticité de la chaussure lui permet sans autre de passer le point d'alignement et d'ouvrir le mécanisme. Ceci est le cas lorsque le skieur ne désire pas dé­chausser, mais simplement libérer l'articulation de la tige 2 pour permettre une station debout confortable ou la marche. Si par contre la boucle 38 est préalable­ment ouverte, l'utilisateur ne rencontre que des résistances de frottement. On voit à la figure 10 que la tige 2 pivote largement vers l'arrière dans la di­rection de la flèche F2 permettant un dégagement aisé du pied de la chaussure.When the skier wishes to take off his shoe, he pulls on the end 37 of the lever 29 in the direction of the arrow F1, FIG. 10. Given the non-alignment of the axes 30, 32 and 35, this traction has first of all tendency to separate the axes 30 and 35 from one another. If the buckle 38 is still closed and tight, the user encounters a certain resistance, but the elasticity of the shoe allows him without other to pass the point d alignment and open the mechanism. This is the case when the skier does not wish to take off his shoes, but simply release the articulation of the rod 2 to allow comfortable standing or walking. If on the other hand the loop 38 is previously open, the user encounters only friction resistances. We see in Figure 10 that the rod 2 pivots widely backwards in the direction of the arrow F2 allowing easy release of the foot of the shoe.

Inversément, lors du chaussage, le skieur peut aisément introduire le pied dans la chaussure dans la position représentée à la figure 10, puis il appuie sur le levier 29 dans le sens de la flèche F3, figure 11, ce qui a pour effet de faire pivoter la tige 2 autour de l'axe 5 dans la direction de la flèche F4 lorsque l'axe 35 atteint l'extrémité supérieure des lumières 36.Conversely, during putting on, the skier can easily introduce the foot into the boot in the position shown in FIG. 10, then he presses the lever 29 in the direction of the arrow F3, FIG. 11, which has the effect of making pivot the rod 2 around the axis 5 in the direction of the arrow F4 when the axis 35 reaches the upper end of the lights 36.

Il serait bien entendu sans autre possible d'articuler l'extrémité inférieure du levier 29 sur la pièce rap­portée 23 de la figure 5 ou dans l'alvéole 26 des figures 6 et 7 ou dans le prolongement 20 du support plantaire 19. Dans le cas de la pièce rapportée 23 et de la partie 20 du support plantaire, il suffit de pré­voir une rainure horizontale pour loger l'extrémité inférieure du levier 29. On relèvera en outre que l'articulation de la genouillère à la chaussure ne né­cessite aucune pièce métallique auxiliaire.It would of course be without other possibility to articulate the lower end of the lever 29 on the insert 23 of Figure 5 or in the socket 26 of Figures 6 and 7 or in the extension 20 of the plantar support 19. In the case of the insert 23 and of the part 20 of the plantar support, it suffices to provide a horizontal groove to accommodate the lower end of the lever 29. It will also be noted that the articulation of the toggle joint to the shoe does not require any metal part auxiliary.

Les chaussures décrites ci-dessus et représentées au dessin comprennent une tige en une seule pièce. La tige pourrait toutefois aussi bien être en deux pièces, comme c'est le cas des chaussures connues dites chaus­sures à chaussage par l'arrière. Dans ce cas, la partie arrière de la tige peut être réalisée exactement de la même manière que la partie arrière de la tige 2 représentée et elle peut également recevoir l'extrémité d'un mécanisme à genouillère tel que représenté.The shoes described above and shown in the drawing include a one-piece upper. The upper could however also be in two pieces, as is the case with known shoes known as rear-fitting shoes. In this case, the rear part of the rod can be produced in exactly the same way as the rear part of the rod 2 shown and it can also receive the end of a toggle mechanism as shown.
