Definitions
- the invention relates to a closure and clamping device for sports shoes, in particular ski boots, comprising a base, a lever-tensioner articulated on this base and having a longitudinal cut in which is engaged a tie rod articulated at an intermediate point on the lever-tensioner, a first fastening member at one end of the tie rod and a second fastening member for fastening the first fastening member for closing and tightening the boot.
- Such a device is known, for example, from US Pat. No. 4,051,611. Since the publication of this patent, the device has been the subject of numerous alternative embodiments and improvements. In particular, the lever-tensioner has been equipped with a spring tending to keep it folded against the boot, see for example FR2729547. Despite all the improvements made to this type of device, a significant disadvantage remains. After the opening maneuver of the device, the attachment member attached to the tie tends to fall on the fastening member attached to a flap opposite the shoe. However, the latter generally has several attachment points, so that the fastening member secured to the tie rod is hooked again to the other fastening member, preventing the opening of the shoe necessary for heaving. .
- DE 3132042 discloses a spring between the tie rod and lever to maintain the tie rod and the first fastening member along the boot.
- the invention aims to avoid this constraint.
- the closure and clamping device is characterized in that it comprises a spring bearing, on the one hand, on the tensioning lever and, on the other hand, on the tie rod tending to maintain the tie rod in an oblique position, spaced apart from the second attachment member.
- the spring is advantageously of the horn type wound around the axis of articulation of the tie rod.
- the first attachment member must not necessarily be hinged to the end of the tie, but it can be rigidly connected to the tie rod or even come from a room with the tie rod. In the case where the first attachment member is articulated to the end of the tie rod, this joint will be greasy friction so that the fastening member is raised with the tie rod.
- the first attachment member may also have some flexibility. It is thus seen that one retains a great freedom of execution of the first attachment member.
- the ends of the hunting horn spring rest on the inner face of the tensioning lever on either side of the hinge pin and the spring presents a first part wound on one side of the tie rod, a second portion wound on the other side of the tie rod and an intermediate portion bearing on the tie rod.
- the intermediate portion of the spring can be supported in different ways on the tie rod. It can rely on pulling only one side of its hinge pin on the lever-tensioner, in particular in an axial slot of the tie rod or on both sides of the hinge pin.

Description
L'invention concerne un dispositif de fermeture et de serrage pour chaussure de sport, en particulier chaussure de ski, comprenant une embase, un levier-tendeur articulé sur cette embase et présentant une découpe longitudinale dans laquelle est engagé un tirant articulé en un point intermédiaire sur le levier-tendeur, un premier organe d'accrochage à une extrémité du tirant et un second organe d'accrochage destiné à l'accrochage du premier organe d'accrochage pour la fermeture et le serrage de la chaussure.The invention relates to a closure and clamping device for sports shoes, in particular ski boots, comprising a base, a lever-tensioner articulated on this base and having a longitudinal cut in which is engaged a tie rod articulated at an intermediate point on the lever-tensioner, a first fastening member at one end of the tie rod and a second fastening member for fastening the first fastening member for closing and tightening the boot.
Un tel dispositif est connu, par exemple, du brevet US 4,051,611. Depuis la publication de ce brevet, le dispositif a fait l'objet de nombreuses variantes d'exécution et de perfectionnements. En particulier, le levier-tendeur a été équipé d'un ressort tendant à le maintenir rabattu contre la chaussure , voir par exemple FR2729547. Malgré tous les perfectionnements apportés à ce type de dispositif, un inconvénient important subsiste. Après la manoeuvre d'ouverture du dispositif, l'organe d'accrochage attaché au tirant a tendance à retomber sur l'organe d'accrochage fixé sur un rabat opposé de la chaussure. Or, ce dernier présente généralement plusieurs points d'accrochage, de telle sorte que l'organe d'accrochage solidaire du tirant vient s'accrocher à nouveau à l'autre organe d'accrochage, empêchant l'ouverture de la chaussure nécessaire au déchaussage. Il a déjà été proposé, dans le document FR2729547, de remédier à cet inconvénient en montant un ressort en cor de chasse autour de l'axe d'articulation du premier organe d'accrochage au tirant, ce ressort tendant à maintenir l'organe d'accrochage dans une position écartée de la crémaillère dans laquelle il est destiné à venir s'accrocher. Cette solution exige que l'organe d'accrochage soit articulé à l'extrémité du tirant et la présence d'un ressort à un endroit peu favorable sur les plans mécanique et esthétique.Such a device is known, for example, from US Pat. No. 4,051,611. Since the publication of this patent, the device has been the subject of numerous alternative embodiments and improvements. In particular, the lever-tensioner has been equipped with a spring tending to keep it folded against the boot, see for example FR2729547. Despite all the improvements made to this type of device, a significant disadvantage remains. After the opening maneuver of the device, the attachment member attached to the tie tends to fall on the fastening member attached to a flap opposite the shoe. However, the latter generally has several attachment points, so that the fastening member secured to the tie rod is hooked again to the other fastening member, preventing the opening of the shoe necessary for heaving. . It has already been proposed, in document FR2729547, to remedy this drawback by mounting a horn spring around the axis of articulation of the first attachment member to pulling, this spring tending to maintain the latching member in a position away from the rack in which it is intended to hang. This solution requires that the attachment member is articulated to the end of the tie rod and the presence of a spring in a location that is not very favorable mechanically and aesthetically.
DE 3132042 décrit un ressort entre le tirant et levier-tendeur afin de maintenir le tirant et le premier organe d'accrochage le long de la chaussure.DE 3132042 discloses a spring between the tie rod and lever to maintain the tie rod and the first fastening member along the boot.
L'invention vise à éviter cette contrainte.The invention aims to avoid this constraint.
Le dispositif de fermeture et de serrage selon l'invention est caractérisé en ce qu'il comprend un ressort prenant appui, d'une part, sur le levier-tendeur et, d'autre part, sur le tirant en tendant à maintenir le tirant dans une position oblique, écarté du second organe d'accrochage.The closure and clamping device according to the invention is characterized in that it comprises a spring bearing, on the one hand, on the tensioning lever and, on the other hand, on the tie rod tending to maintain the tie rod in an oblique position, spaced apart from the second attachment member.
Le ressort est avantageusement du type en cor de chasse enroulé autour de l'axe d'articulation du tirant.The spring is advantageously of the horn type wound around the axis of articulation of the tie rod.
Le premier organe d'accrochage ne doit pas être obligatoirement articulé à l'extrémité du tirant, mais il peut être rigidement relié au tirant ou même venu d'une pièce avec le tirant. Dans le cas où le premier organe d'accrochage est articulé à l'extrémité du tirant, cette articulation sera à frottement gras de telle manière que l'organe d'accrochage se relève avec le tirant. Le premier organe d'accrochage pourra également présenter une certaine flexibilité. On voit ainsi que l'on conserve une grande liberté d'exécution du premier organe d'accrochage.The first attachment member must not necessarily be hinged to the end of the tie, but it can be rigidly connected to the tie rod or even come from a room with the tie rod. In the case where the first attachment member is articulated to the end of the tie rod, this joint will be greasy friction so that the fastening member is raised with the tie rod. The first attachment member may also have some flexibility. It is thus seen that one retains a great freedom of execution of the first attachment member.
Selon des modes d'exécution préférés de l'invention, les extrémités du ressort en cor de chasse s'appuient sur la face interne du levier-tendeur de part et d'autre de l'axe d'articulation et le ressort présente une première partie enroulée d'un côté du tirant, une deuxième partie enroulée de l'autre côté du tirant et une partie intermédiaire prenant appui sur le tirant.According to preferred embodiments of the invention, the ends of the hunting horn spring rest on the inner face of the tensioning lever on either side of the hinge pin and the spring presents a first part wound on one side of the tie rod, a second portion wound on the other side of the tie rod and an intermediate portion bearing on the tie rod.
La partie intermédiaire du ressort peut s'appuyer de différentes manières sur le tirant. Elle peut s'appuyer sur le tirant d'un seul côté de son axe d'articulation sur le levier-tendeur, en particulier dans une fente axiale du tirant ou des deux côtés de l'axe d'articulation.The intermediate portion of the spring can be supported in different ways on the tie rod. It can rely on pulling only one side of its hinge pin on the lever-tensioner, in particular in an axial slot of the tie rod or on both sides of the hinge pin.
Le dessin annexé représente, à titre d'exemple, des modes d'exécution de l'invention.The appended drawing represents, by way of example, embodiments of the invention.
