Description

La présente invention concerne une chaussure de ski alpin, comportant un bas de coque sur la partie arrière duquel est montée au moins partiellement pivotante, autour d'un axe transversal à l'axe longitudinal du bas de coque, la tige de la chaussure.The present invention relates to an alpine ski boot, comprising a shell bottom on the rear part of which is mounted at least partially pivoting, around an axis transverse to the longitudinal axis of the shell bottom, the upper of the boot.

Les chaussures de ski alpin à tige pivotante offrent l'avantage, par rapport aux chaussures utilisées antérieurement, à tige formant une seule pièce avec le bas de la chaussure, que la tige peut suivre les mouvements de flexion vers l'avant et vers l'arrière du bas de jambe du skieur, pendant la marche et la pratique du ski, et que cette tige peut également basculer vers l'arrière, totalement ou partiellement, pour faciliter le chaussage et le déchaussage. La tige pivotante peut être constituée d'une seule pièce et elle forme alors un collier entourant la totalité du bas de jambe. Elle peut comprendre également deux parties constitutives, à savoir une partie avant ou manchette, coiffant le cou-de-pied, solidaire du bas de coque ou pivotant sur ce bas de coque, et une partie arrière ou capot arrière, entourant l'arrière du bas de jambe.Alpine ski boots with pivoting rod offer the advantage, compared to the shoes used previously, with rod forming a single piece with the bottom of the boot, that the rod can follow the movements of bending forward and towards the back of the skier's lower leg, while walking and skiing, and this rod can also tilt backwards, totally or partially, to facilitate putting on and taking off. The pivoting rod can be made in one piece and it then forms a collar surrounding the entire lower leg. It can also include two constituent parts, namely a front part or cuff, covering the instep, integral with the bottom of the hull or pivoting on the bottom of the hull, and a rear part or rear cover, surrounding the rear of the lower leg.

Parmi les chaussures de ski alpin connues à ce jour certaines comportent une tige dont la partie arrière présente une paroi postérieure sensiblement plane qui est légèrement inclinée de bas en haut vers l'avant, en position de pratique du ski, lorsque la tige de la chaussure est serrée autour du bas de jambe du skieur. La forme plane d'une telle paroi postérieure et son inclinaison vers l'avant sont choisies de manière à assurer une bonne rigidité de la partie arrière de la tige lors des appuis postéro-antérieurs ou antéro-postérieurs pendant la pratique du ski. En effet l'évolution de la technique de ski actuelle favorise des reprises d'appui arrière très importantes, ce qui nécessite une grande rigidité de la tige après le blocage de celle-ci par rapport au bas de coque. Pour augmenter cette rigidité il a été prévu, notamment dans les chaussures fabriquées par la demanderesse sous les marques SX82 et SX92, des chaussures qui présentent, sur la paroi postérieure de leur capot arrière, deux nervures latérales parallèles qui contribuent à augmenter la rigidité de ce capot arrière pendant les flexions de la tige vers l'avant ou vers l'arrière.Among the alpine ski boots known to date, some have a rod, the rear part of which has a substantially planar rear wall which is slightly inclined from the bottom upwards towards the front, in the skiing practice position, when the shoe upper is tightened around the lower leg of the skier. The flat shape of such a rear wall and its forward inclination are chosen so as to ensure good rigidity of the rear part of the rod during postero-anterior or antero-posterior supports during skiing. In fact, the evolution of the current ski technique favors very large rear support times, which requires great rigidity of the rod after the latter has been blocked relative to the bottom of the hull. To increase this rigidity, provision has been made, in particular in the shoes manufactured by the applicant under the brands SX82 and SX92, shoes which have, on the rear wall of their rear cover, two parallel lateral ribs which contribute to increasing the rigidity of this rear cover during bending of the rod forwards or backwards.

Dans d'autres chaussures de ski alpin on a cherché à faire en sorte que la paroi postérieure de la partie arrière de la tige soit aussi proche que possible, en tous points, du profil de l'arrière du bas de jambe du skieur. En effet une telle construction permet de réduire au minimum le volume de la chaussure et par conséquent d'utiliser moins de matériau pour sa fabrication, ce qui se traduit par une économie appréciable lors de la fabrication en grande série et également par l'obtention d'une chaussure plus légère. Toutefois une telle construction a pour conséquence que, par suite du contact étroit entre le bas de jambe du skieur et la paroi postérieure de la tige, cette paroi postérieure présente une surface courbe, à concavité tournée vers l'arrière et à grand rayon de courbure. Or une telle surface arrière concave entraîne une diminution de la rigidité de la partie arrière de la tige à l'encontre d'efforts s'exerçant, pendant la pratique du ski, sur sa partie supérieure, si bien que la paroi postérieure de la tige a une certaine tendance à fléchir, ce qui est contraire au résultat recherché.In other alpine ski boots, attempts have been made to ensure that the rear wall of the rear part of the upper is as close as possible, in all points, to the profile of the rear of the skier's lower leg. Indeed, such a construction makes it possible to minimize the volume of the shoe and therefore to use less material for its manufacture, which translates into appreciable savings during mass production and also by obtaining 'a lighter shoe. However, such a construction has the consequence that, as a result of the close contact between the lower leg of the skier and the rear wall of the rod, this rear wall has a curved surface, with a concavity turned towards the rear and with a large radius of curvature. . However, such a concave rear surface results in a reduction in the rigidity of the rear part of the rod against forces exerted, during skiing, on its upper part, so that the rear wall of the rod has a certain tendency to bend, which is contrary to the desired result.

La présente invention concerne des améliorations apportées aux chaussures de ski alpin précitées dans le but d'obtenir une rigidité renforcée à l'égard des appuis postéro-antérieurs ou antéro-postérieurs pendant la pratique du ski.The present invention relates to improvements made to the aforementioned alpine ski boots with the aim of obtaining increased rigidity with respect to postero-anterior or antero-posterior supports during skiing.

A cet effet, cette chaussure de ski alpin, comportant un bas de coque et une tige montée pivotante sur ce bas de coque, autour d'un axe horizontal et transversal, la partie arrière de la tige comprenant une paroi postérieure s'étendant le long de l'arrière du bas de jambe du skieur, est caractérisée en ce que la paroi postérieure de la tige est consolidée par une entretoise de rigidification monobloc qui s'étend, à distance de la paroi postérieure de la tige, entre les parties supérieure et inférieure de cette paroi postérieure, et en ce qu'au moins un tirant établit une liaison mécanique rigide entre une zone intermédiaire de l'entretoise de rigidification et une zone intermédiaire de la paroi postérieure de la tige.To this end, this alpine ski boot, comprising a shell bottom and a rod pivotally mounted on this shell shell, about a horizontal and transverse axis, the rear part of the rod comprising a rear wall extending along from the back of the lower leg of the skier, is characterized in that the rear wall of the rod is consolidated by a one-piece stiffening spacer which extends, at a distance from the rear wall of the rod, between the upper parts and lower of this rear wall, and in that at least one tie establishes a rigid mechanical connection between an intermediate zone of the stiffening spacer and an intermediate zone of the rear wall of the rod.

On décrira ci-après, à titre d'exemples non limitatifs, diverses formes d'exécution de la présente invention, en référence au dessin annexé sur lequel :Various embodiments of the present invention will be described below, by way of nonlimiting examples, with reference to the appended drawing in which:

La figure 1 est une vue en élévation d'une chaussure de ski alpin à entrée arrière suivant l'invention, en position de pratique du ski.Figure 1 is an elevational view of an alpine ski boot with rear entry according to the invention, in the skiing position.

La figure 2 est une vue en élévation de la chaussure de ski alpin représentée sur la figure 1, avec sa tige ouverte basculée vers l'arrière en position de chaussage-déchaussage.Figure 2 is an elevational view of the alpine ski boot shown in Figure 1, with its open upper tilted backwards in the boot-release position.

La figure 3 est une vue en perspective, prise de l'arrière et du dessus, de la chaussure de ski alpin de la figure 1.FIG. 3 is a perspective view, taken from the rear and from above, of the alpine ski boot of FIG. 1.

Les figures 4 et 5 sont des vues en élévation de variantes d'exécution de l'entretoise de rigidification de la chaussure de ski alpin des figures 1 à 3.FIGS. 4 and 5 are elevation views of alternative embodiments of the stiffening spacer of the alpine ski boot of FIGS. 1 to 3.

Les figures 5, 6 et 7, illustrent d'autres modes de réalisation de l'invention appliquée à des chaussures de type à entrée centrale ou par le dessus, à entrée par l'avant et à entrée mixte.Figures 5, 6 and 7 illustrate other embodiments of the invention applied to shoes of the central or top entry type, front entry and mixed entry.

La chaussure de ski alpin à entrée arrière suivant l'invention qui est représentée sur les figures 1 à 3, comprend un bas de coque rigide 1 et, à sa partie supérieure, une tige 2 entourant le bas de la jambe d'un skieur, représentée en trait mixte. Dans cette forme d'exécution non limitative, la tige 2 est d'une seule pièce et elle forme un collier dont les deux parties extrêmes antérieures se chevauchent l'une l'autre. Ce collier 2 est monté pivotant, à sa partie inférieure et postérieure, sur le bas de coque 1, autour d'un axe de pivotement horizontal et transversal 3 porté par la paroi postérieure 1a du bas de coque 1. Le collier 2 porte, à sa partie supérieure, un dispositif de serrage du bas de jambe, de tout type connu, comportant un câble ou une sangle de serrage 4, et, à sa partie inférieure et antérieure, un dispositif 5 de serrage du collier 2 sur le bas de coque 1. Ce collier 2 comprend deux parties latérales 2a qui sont percées de trous alignés transversalement et horizontalement et, dans ces trous, s'engagent des tétons respectifs 6 portés par les parties latérales 1b du bas de coque 1 et en saillie vers l'extérieur. Ces tétons 6 servent à immobiliser le collier 2 sur le bas de coque 1, lorsque ce collier 2 est serré sur le bas de coque au moyen du dispositif 5.The alpine ski boot with rear entry according to the invention which is represented in FIGS. 1 to 3, comprises a rigid shell bottom 1 and, at its upper part, a rod 2 surrounding the bottom of the leg of a skier, shown in phantom. In this nonlimiting embodiment, the rod 2 is in one piece and it forms a collar, the two anterior end parts of which overlap one another. This collar 2 is pivotally mounted, at its lower and rear part, on the shell bottom 1, around a horizontal and transverse pivot axis 3 carried by the rear wall 1 a of the shell bottom 1. The collar 2 carries, at its upper part, a lower leg tightening device, of any known type, comprising a cable or a tightening strap 4, and, at its lower and front part, a device 5 for tightening the collar 2 on the lower shell 1. This collar 2 comprises two lateral parts 2a which are pierced with holes aligned transversely and horizontally and, in these holes, engage respective studs 6 carried by the lateral parts 1b of the bottom of shell 1 and projecting towards the outside. These pins 6 serve to immobilize the collar 2 on the bottom of the shell 1, when this collar 2 is tightened on the bottom of the shell by means of the device 5.

Le collier 2 comporte également une paroi postérieure 2b qui est inclinée de bas en haut vers l'avant, en position de pratique du ski, comme il est représenté sur la figure 1. Cette paroi postérieure 2b peut être plane ou bien encore elle peut avoir une forme incurvée de manière à suivre au plus près le profil de l'arrière du bas de jambe du skieur tracé en trait mixte sur la figure 1. De ce fait la paroi postérieure 2b présente, vue de côté, une forme concave vers l'arrière, à grand rayon de courbure. Du fait de cette forme concave, la paroi postérieure 2b du collier 2 offre une résistance réduite aux efforts qui résultent des appuis arrière antéro-postérieurs et postéro-antérieurs du skieur pendant la pratique du ski. Pour compenser cette résistance relativement faible, une entretoise de rigidification monobloc 7 s'étend entre la partie supérieure et la partie inférieure de la paroi postérieure 2b du collier 2. Ainsi l'entretoise de rigidification monobloc7 s'étend entre une zone de liaison supérieure 8, voisine du bord supérieur du collier 2, et une zone de liaison inférieure 9, voisine de l'axe de pivotement inférieur 3 du collier 2. Cette entretoise de rigidification 7 peut être constituée par une pièce rapportée, fixée, à ses extrémités supérieure et inférieure, au collier 2 ou bien encore, ce qui est préférable, elle peut être formée d'une seule pièce avec le collier 2 en venant de moulage avec celui-ci, comme il est représenté sur le dessin.The collar 2 also includes a rear wall 2b which is inclined from the bottom upwards towards the front, in the skiing practice position, as shown in FIG. 1. This rear wall 2b can be flat or else it can have a curved shape so as to follow as closely as possible the profile of the back of the lower leg of the skier drawn in phantom in Figure 1. Therefore the rear wall 2b has, seen from the side, a concave shape towards the rear, with large radius of curvature. Due to this concave shape, the rear wall 2b of the collar 2 offers reduced resistance to forces that result from the anteroposterior and posterior anterior supports of the skier during skiing. To compensate for this relatively low resistance, a single-piece stiffening spacer 7 extends between the upper part and the lower part of the rear wall 2b of the collar 2. Thus the single-piece stiffening spacer 7 extends between an upper connection zone 8 , close to the upper edge of the collar 2, and a lower connection zone 9, close to the lower pivot axis 3 of the collar 2. This stiffening spacer 7 can be constituted by an insert, fixed at its upper ends and lower, to the collar 2 or even, which is preferable, it can be formed in one piece with the collar 2 by molding therewith, as shown in the drawing.

L'entretoise de rigidification 7 peut être rectiligne ou bien, de préférence, elle peut présenter une légère convexité vers l'arrière si bien que la paroi postérieure 2b et l'entretoise de rigidification 7 forment conjointement, vues de côté, une sorte de fuseau.The stiffening spacer 7 can be straight or, preferably, it can have a slight rearward convexity so that the rear wall 2b and the stiffening spacer 7 jointly form, seen from the side, a kind of spindle .

La rigidification de la paroi postérieure 2b du collier 2 est également assurée par au moins un tirant 11 reliant une zone intermédiaire de l'entretoise de rigidification 7 et une zone intermédiaire en regard de la paroi postérieure 2b du collier 2, de manière à empêcher que lesdites zones puissent s'écarter ou se rapprocher l'une de l'autre.The stiffening of the rear wall 2b of the collar 2 is also ensured by at least one tie rod 11 connecting an intermediate zone of the stiffening spacer 7 and an intermediate zone facing the rear wall 2b of the collar 2, so as to prevent said zones can deviate from or approach each other.

La chaussure peut comporter un seul tirant de rigidification 11 comme il est représenté sur les figures 1 à 3. Dans ce cas le tirant de rigidification unique 11 s'étend sensiblement entre les zones médianes de la paroi postérieure 2b et de l'entretoise de rigidification 7, c'est-à-dire les zones les plus exposées au flambage. Dans cette forme d'exécution également le tirant de rigidification 11 est incliné de bas en haut et d'avant en arrière.The shoe may comprise a single stiffening tie 11 as shown in FIGS. 1 to 3. In this case the single stiffening tie 11 extends substantially between the median zones of the rear wall 2b and of the stiffening spacer. 7, that is to say the areas most exposed to buckling. In this embodiment also the stiffening rod 11 is inclined from bottom to top and from front to back.

L'entretoise de rigidification 7 peut avoir une largeur constante de haut en bas ou bien encore, comme il apparaît plus nettement sur la figure 3, cette largeur peut aller en diminuant de haut en bas de la zone de liaison supérieure 8 à la zone intermédiaire où se trouve le tirant 11 et en augmentant ensuite progressivement jusqu'à la zone de liaison inférieure 9.The stiffening spacer 7 can have a constant width from top to bottom or even, as it appears more clearly in FIG. 3, this width can decrease from top to bottom from the upper connection zone 8 to the intermediate zone where the tie rod 11 is located and then gradually increasing to the lower connecting zone 9.

Dans la variante d'exécution représentée sur la figure 4, l'entretoise de rigidification 7 est reliée à la paroi postérieure 2b du collier 2 par l'intermédiaire de deux tirants 11a qui sont sensiblement perpendiculaires à la corde A, tracée en trait mixte, s'étendant entre les deux zones de liaison supérieure 8 et inférieure 9.In the variant shown in FIG. 4, the stiffening spacer 7 is connected to the rear wall 2b of the collar 2 by means of two tie rods 11a which are substantially perpendicular to the rope A, drawn in dashed lines, extending between the two upper 8 and lower 9 connection zones.

La figure 5 représente une variante d'exécution dans laquelle l'entretoise de rigidification 7 est reliée à la paroi postérieure 2b du collier 2 par l'intermédiaire de deux tirants parallèles 11b inclinés de haut en bas vers l'avant. De préférence le ou les tirants inclinés sont sensiblement parallèles à une droite passant par l'extrémité avant de la semelle de la chaussure et par un point situé à mi-hauteur de la tige.FIG. 5 represents an alternative embodiment in which the stiffening spacer 7 is connected to the rear wall 2b of the collar 2 by means of two parallel tie rods 11b inclined up and down towards the front. Preferably the inclined tie rod (s) are substantially parallel to a straight line passing through the front end of the sole of the shoe and through a point located halfway up the upper.

Les chaussures qui viennent d'être décrites en référence aux figures 1 à 5 précédentes comportent un collier 2 dont les parties latérales 2a s'accrochent sur des têtons 6 portés par les parties latérales 1b du bas de coque 1. Il est évident que la réalisation d'une poutre de rigidification conforme à l'invention peut avantageusement être appliquée à des chaussures non munies d'un tel accrochage de tige et également à des chaussures de ski d'un type différent de celui à "entrée par l'arrière" ; à titre d'exemples non limitatifs, les figures 6 à 8 qui suivent, illustrent, schématiquement des chaussures de types différents dans lesquels :The shoes which have just been described with reference to FIGS. 1 to 5 above include a collar 2, the lateral parts 2a of which hang onto pins 6 carried by the lateral parts 1b of the bottom of the shell 1. It is obvious that the embodiment of a stiffening beam according to the invention can advantageously be applied to boots not provided with such an attachment of upper and also to ski boots of a type different from that with "entry by the rear "; by way of nonlimiting examples, FIGS. 6 to 8 which follow schematically illustrate shoes of different types in which:

La figure 6 représente une variante d'exécution de l'invention appliquée à une chaussure de ski du type à entrée centrale et/ou par l'arrière dont la tige 2 est constituée de deux parties indépendantes à savoir une manchette avant 14 et un capot arrière 15. Ces deux parties indépendantes sont articulées, à leurs parties inférieures, sur le bas de coque 1, autour d'un axe horizontal et transversal commun 16. Dans ce cas l'entretoise de rigidification 7 et le ou les tirants 11 font partie intégrante du capot arrière 15. L'entretoise 7 s'étend entre les parties supérieure 8 et inférieure 9 de la paroi postérieure 15a du capot arrière et le ou les tirants 11 s'étendent entre l'entretoise 7 et la paroi postérieure 15a du capot arrière 15.FIG. 6 represents an alternative embodiment of the invention applied to a ski boot of the central entry and / or rear type, the upper 2 of which consists of two independent parts, namely a front cuff 14 and a cover rear 15. These two independent parts are articulated, at their lower parts, on the shell bottom 1, around a common horizontal and transverse axis 16. In this case the stiffening spacer 7 and the tie rod (s) 11 are part integral of the rear cover 15. The spacer 7 extends between the upper 8 and lower 9 parts of the rear wall 15a of the rear cover and the tie rod (s) 11 extend between the spacer 7 and the rear wall 15a of the cover rear 15.

La figure 7 illustre une chaussure de ski du type à entrée mixte ou à entrée par le dessus dans laquelle la tige 2 présente un capot arrière 25 qui est susceptible de basculer dans le sens antéro-postérieur autour d'un axe 16, tandis que le capot avant 24, constitué d'un capot d'un seul tenant, est articulé dans la zone du bout de la chaussure par l'intermédiaire d'une liaison articulée 23 pour permettre le chaussage et/ou le déchaussage par le dessus de la chaussure. Dans cet exemple de construction la poutre de rigidification 7 est reliée à la paroi postérieure 25a du capot arrière 25 par l'intermédiaire de ses deux extrémités de liaison 8, 9 et par l'intermédiaire de deux tirants 11c parallèles entre eux et inclinés de haut en bas vers l'arrière.FIG. 7 illustrates a ski boot of the mixed entry or top entry type in which the upper 2 has a rear cover 25 which is capable of tilting in the anteroposterior direction around an axis 16, while the front cover 24, consisting of a single-piece cover, is articulated in the area of the toe of the shoe by means of an articulated link 23 to allow putting on and / or taking off from above the shoe . In this example of construction, the stiffening beam 7 is connected to the rear wall 25a of the rear cover 25 by means of its two connection ends 8, 9 and by means of two tie rods 11c which are parallel to one another and inclined from above. down to the back.

La figure 8 montre une chaussure de ski du type à entrée mixte dans laquelle la tige 2 comporte un collier 35 de tenue du bas de jambe et une partie antérieurs 34 venue du bas de coque 1 destinée à être enserrée par ledit collier 35. La partie antérieure 34 de la tige est, dans ce mode de construction, constituée d'une languette transversale 30 qui vient en recouvrement d'une autre languette 30a, opposée, les deux languettes s'étendant respectivement, à partir d'un flanc du bas de coque 1. Il est ainsi possible d'ouvrir la zone de la chaussure correspondant à cette partie antérieur 34 après libération du collier 35 pour l'introduction ou l'extraction du pied par écartement desdites languettes. Toujours conformément à l'invention, la poutre de rigidification 7 est reliée dans sa zone médiane, à la paroi postérieure 35a du collier 35 par l'intermédiaire de deux tirants 11d sensiblement disposés en V à partir de ladite paroi 35a. Il est évident que les tirants 11d peuvent être inclinés l'un par rapport à l'autre selon des angles différents et être plus ou moins éloignés d'un de l'autre sans que l'on sorte pour cela du cadre de l'invention.FIG. 8 shows a ski boot of the mixed entry type in which the upper 2 comprises a collar 35 for holding the lower leg and an anterior part 34 coming from the bottom of the shell 1 intended to be clamped by said collar 35. The part anterior 34 of the rod is, in this construction method, constituted by a transverse tongue 30 which overlaps another tongue 30a, opposite, the two tongues extending respectively, from a flank of the bottom of shell 1. It is thus possible to open the zone of the shoe corresponding to this front part 34 after release of the collar 35 for the introduction or the extraction of the foot by spacing of said tabs. Still in accordance with the invention, the stiffening beam 7 is connected in its median zone to the rear wall 35a of the collar 35 by means of two tie rods 11d substantially arranged in a V shape from said wall 35a. It is obvious that the tie rods 11d can be inclined relative to each other at different angles and be more or less distant from one another without departing from the scope of the invention. .
