Abstract

The braking arms of the ski brake are carried solely by an operating pedal which is pivoted to the ski about a transverse axis. The corresponding control ends of the braking arms are elbowed so as to form a V, the point of which is directed away from the braking shoes and/or away from the top face of the ski. The control ends are rotatably mounted within bores having the same angular orientation and formed in the operating pedal. By means of an elastic plug applied against a flat face formed in each control end, the braking arms are caused to rotate upon completion of an upward displacement and the active ends of the arms are automatically restored to their inwardly withdrawn position above the ski.

Description

La présente invention est relative à un frein à ski comportant deux bras mobiles de freinage, destinés à être disposés de part et d'autre d'un ski, et dont les extrémités actives sont rétractées au-dessus du ski dans leur position de relèvement, tandis que leurs extrémités opposées sont réunies par une pédale de commande susceptible d'être actionnée par la chaussure correspondante du skieur, les bras de freinage étant exclusivement portés par la pédale de commande qui s'articule sur le ski autour d'un axe transversal.The present invention relates to a ski brake comprising two movable braking arms, intended to be arranged on either side of a ski, and the active ends of which are retracted above the ski in their raised position, while their opposite ends are joined by a control pedal capable of being actuated by the corresponding shoe of the skier, the braking arms being exclusively carried by the control pedal which is articulated on the ski around a transverse axis.

Plus précisément l'invention concerne les freins à ski de ce genre dont l'agencement est tel que les extrémités actives des deux bras mobiles de freinage soient rétractées au-dessus du ski lorsque celles-ci sont relevées en position d'escamotage.More specifically, the invention relates to ski brakes of this kind, the arrangement of which is such that the active ends of the two movable braking arms are retracted above the ski when these are raised in the retracted position.

Il existe déjà un grand nombre de freins à ski ainsi conçus de façon à éviter que dans leur position de relèvement, les extrémités actives des bras de freinage débordent par rapport aux chants latéraux du ski.There are already a large number of ski brakes thus designed so as to prevent the active ends of the braking arms from overhanging with respect to the side edges of the ski in their lifting position.

Ainsi la figure 7 du brevet français FR-A-2 055 424 décrit un frein à ski dans lequel les bras de freinage sont rétractés en position d'escamotage grâce à un pivotement autour d'un axe longitudinal.Thus, FIG. 7 of French patent FR-A-2 055 424 describes a ski brake in which the brake arms are retracted into the retracted position thanks to a pivoting around a longitudinal axis.

L'amplitude de cette rétraction est égale à la distance d'écartement des bras de freinage par rapport à cet axe. Cependant cette solution a pour inconvénient d'impliquer un encombrement important de ce frein dans le sens de la hauteur. C'est du reste la raison pour laquelle un frein de ce type ne peut pas être monté dans une position centrale d'escamotage au-dessous de la chaussure.The amplitude of this retraction is equal to the distance of separation of the braking arms relative to this axis. However, this solution has the drawback of involving a large size of this brake in the height direction. This is, moreover, the reason why a brake of this type cannot be mounted in a central retracting position below the shoe.

Par ailleurs, pour assurer la rétraction des bras de freinage, il est nécessaire de prévoir des organes mobiles de commande. Ceci entraîne une relative complexité de ce frein et un prix de revient élevé.Furthermore, to ensure the retraction of the braking arms, it is necessary to provide movable control members. This results in a relative complexity of this brake and a high cost price.

La demande de brevet français FR-A-2 447 208 décrit également un frein dont les bras de freinage se trouvent rétractés en position d'escamotage. Cette rétraction est obtenue par un mouvement de pivotement des bras de freinage assurant un relèvement de leurs extrémités actives au-dessus du ski. Cependant là encore, ceci a pour inconvénient d'impliquer un encombrement important de ce frein dans le sens de la hauteur.French patent application FR-A-2 447 208 also describes a brake, the braking arms of which are retracted in the retracted position. This retraction is obtained by a pivoting movement of the braking arms ensuring a raising of their active ends above the ski. However, here again, this has the drawback of involving a large size of this brake in the height direction.

Les demandes de brevets français FR-A-2451 754 et FR-A-2 452 300 ont pour objet des freins à ski dans lesquels la rétraction des patins de freinage est obtenue en quelque sorte par un mouvement d'oscillation des deux bras correspondants dans le sens transversal grâce à un débattement de ceux-ci à l'intérieur des paliers dans lesquels s'articulent leurs parties coudées servant d'axes de pivotement. Ce mouvement d'oscillation est alors commandé par le pivotement relatif qui se produit entre la pédale de commande et les extrémités correspondantes des bras de freinage en fin de mouvement de relèvement de ces derniers.French patent applications FR-A-2451 754 and FR-A-2 452 300 relate to ski brakes in which the retraction of the brake pads is obtained in a way by an oscillating movement of the two corresponding arms in the transverse direction thanks to a movement of these inside the bearings in which their bent parts are articulated serving as pivot axes. This oscillation movement is then controlled by the relative pivoting which occurs between the control pedal and the corresponding ends of the brake arms at the end of the lifting movement of the latter.

A cet effet les extrémités de ces bras sont coudées de façon à présenter une orientation particulière qui détermine ce mouvement d'oscillation lors du pivotement relatif de la pédale de commande par rapport aux bras de freinage.To this end the ends of these arms are bent so as to have a particular orientation which determines this oscillation movement during the relative pivoting of the control pedal relative to the braking arms.

Cette solution donne entière satisfaction. Toutefois les freins de ce type sont relativement coûteux du fait que leurs bras de freinage doivent présenter des coudes multiples correspondant à leurs diverses parties.This solution is entirely satisfactory. However, brakes of this type are relatively expensive because their braking arms must have multiple bends corresponding to their various parts.

Par ailleurs, pour faire passer ces bras de freinage de leur position relevée à leur position finale de rétraction, il faut exercer une force verticale importante sur la pédale de commande, en raison des frottements se produisant entre les bras de freinage et leurs paliers d'articulation. Du reste ceci peut gêner le chaussage du ski dans certaines conditions, par exemple dans le cas d'un skieur de faible poids, ou bien encore lorsque l'on se trouve sur de la neige poudreuse.Furthermore, to move these braking arms from their raised position to their final retraction position, it is necessary to exert a large vertical force on the control pedal, due to the friction occurring between the braking arms and their bearings. joint. Moreover, this can interfere with the ski boot in certain conditions, for example in the case of a skier of low weight, or even when one is on powder snow.

Comme ces frottements existent également dans le sens inverse, c'est-à-dire lors du déploiement du frein en position de travail, il est nécessaire de prévoir un ressort de rappel relativement puissant. Mais l'existence d'un tel ressort a pour inconvénient que le frein exerce, contre la chaussure, une poussée verticale appréciable qui peut nuire au bon rappel de celle-ci par une fixation élastique de sécurité.As this friction also exists in the opposite direction, that is to say during the deployment of the brake in the working position, it is necessary to provide a relatively powerful return spring. However, the existence of such a spring has the disadvantage that the brake exerts, against the shoe, an appreciable vertical thrust which can hinder the correct return of the latter by an elastic safety attachment.

C'est pourquoi la présente invention a pour but de réaliser un frein à ski du même type général, mais qui est conçu de façon à éviter les inconvénients rappelés ci-dessus. La conception de ce frein est donc telle que celui-ci soit particulièrement simple et peu coûteux. Cette conception est également telle que l'escamotage de ce frein puisse s'effectuer sans efforts importants et qu'il soit possible de prévoir un ressort de rappel de puissance limitée.This is why the present invention aims to achieve a ski brake of the same general type, but which is designed so as to avoid the drawbacks mentioned above. The design of this brake is therefore such that it is particularly simple and inexpensive. This design is also such that the retraction of this brake can be carried out without significant efforts and that it is possible to provide a return spring of limited power.

A cet effet les extrémités opposées des bras de freinage du frein à ski selon l'invention sont coudées pour former un V ayant sa pointe dirigée du côté opposé aux extrémités actives de ces bras et/ou du côté opposé au ski et sont montées tourillonnantes dans des alésages, de même orientation angulaire, ménagés dans la pédale, cependant qu'il est prévu des moyens provoquant la rotation des bras de freinage sur eux-mêmes dans ces alésages, après leur relèvement, pour que leurs extrémités actives se trouvent ainsi rétractées au-dessus du ski dans la position d'attente de ce frein.For this purpose the opposite ends of the braking arms of the ski brake according to the invention are bent to form a V having its point directed on the side opposite the active ends of these arms and / or on the side opposite to the ski and are mounted swiveling in bores, of the same angular orientation, formed in the pedal, however means are provided which cause the braking arms to rotate on themselves in these bores, after their raising, so that their active ends are thus retracted to the above the ski in the standby position of this brake.

Ainsi la rétraction des extrémités actives des bras de freinage est assurée par une simple rotation des extrémités opposées de ces derniers - à l'intérieur des alésages prévus dans la pédale de commande. Cette rétraction résulte alors de la forme coudée des extrémités correspondantes, des bras de freinage et de l'orientation angulaire correspondante des alésages servant de paliers à ces extrémités.Thus the retraction of the active ends of the braking arms is ensured by a simple rotation of the opposite ends of the latter - inside the bores provided in the control pedal. This retraction then results from the bent shape of the corresponding ends, the braking arms and the corresponding angular orientation of the bores serving as bearings at these ends.

Dans ces conditions le mouvement de rétraction et de déploiement des bras de freinage n'est pas perturbé par des frottements importants nécessitant l'emploi d'un ressort de rappel de faible puissance qui n'a pas l'inconvénient d'engendrer une poussée importante 'contre la chaussure, lorsque ce frein est en position d'escamotage.Under these conditions the back movement tion and deployment of the braking arms is not disturbed by significant friction requiring the use of a low-power return spring which does not have the disadvantage of generating a significant thrust 'against the shoe, when this brake is in the retracted position.

Dans une forme de réalisation particulière du frein selon l'invention, les moyens prévus pour commander la rotation des bras de freinage sur eux-mêmes dans leur position de rétraction, sont constitués par des organes élastiques tendant constamment à provoquer une telle rotation, celle-ci se trouvant empêchée de se produire tant que les bras de freinage n'ont pas été relevés au-dessus de la surface supérieure du ski.In a particular embodiment of the brake according to the invention, the means provided for controlling the rotation of the braking arms on themselves in their retracted position, are constituted by elastic members constantly tending to cause such rotation, ci being prevented from occurring until the braking arms have not been raised above the upper surface of the ski.

Dans une autre forme de réalisation, la rotation des bras de freinage dans leur position de rétraction est provoquée par une butée disposée au-dessus de la position de relèvement des extrémités actives de ces bras. Ainsi cette butée empêche que ces extrémités poursuivent leur mouvement de relèvement lors du rabattement de la pédale de commande contre le ski, ce qui oblige les bras de freinage à tourner sur eux-mêmes dans les alésages prévus à l'intérieur de cette pédale. Eventuel- lement la butée ainsi prévue peut être constituée par un autre élément d'équipement du ski correspondant, par exemple par la plaque rotative d'une talonnière pivotante de fixation.In another embodiment, the rotation of the braking arms in their retracted position is caused by a stop disposed above the position for raising the active ends of these arms. Thus this stop prevents these ends from continuing their lifting movement when the control pedal is folded against the ski, which forces the braking arms to turn on themselves in the bores provided inside this pedal. Optionally, the stop thus provided may be constituted by another element of the corresponding ski equipment, for example by the rotary plate of a pivoting heel piece for fixing.

Le frein à ski représenté aux figures 1 à 7 comporte deux bras mobiles 1, en fil métallique rigide, qui sont destinés à être disposés sur l'un et l'autre côtés du ski correspondant S. Contrairement à ce qui est le cas dans la plupart des freins à ski de ce genre, ces deux bras ne s'articulent pas directement sur le ski. En effet ils sont exclusivement portés par une pédale de commande 2 susceptible d'être actionnée par la chaussure correspondante du skieur. Cette pédale s'articule autour d'un axe 3 qui s'étend dans le sens transversal au-dessus du ski et parallèlement à la surface supérieure de celui-ci, cet axe étant porté par une platine 4 fixée sur le dessus du ski.The ski brake shown in FIGS. 1 to 7 comprises two movable arms 1, made of rigid metal wire, which are intended to be arranged on one and the other sides of the corresponding ski S. Contrary to what is the case in the most ski brakes of this kind, these two arms do not articulate directly on the ski. In fact, they are exclusively carried by a control pedal 2 capable of being actuated by the corresponding shoe of the skier. This pedal is articulated around an axis 3 which extends in the transverse direction above the ski and parallel to the upper surface thereof, this axis being carried by a plate 4 fixed on the top of the ski.

Les deux bras de freinage 1 sont montés sur la pédale de commande 2 par l'intermédiaire de l'une de leurs extrémités, en l'occurrence leur extrémité 5 qui est opposée à l'extrémité active 6 sur laquelle est prévu un patin de freinage 7.The two brake arms 1 are mounted on the control pedal 2 via one of their ends, in this case their end 5 which is opposite to the active end 6 on which a brake shoe is provided. 7.

Les extrémités 5 des deux bras de freinage 1 sont coudées l'une vers l'autre et montées rotatives sur elles-mêmes à l'intérieur d'alésages 8 ménagés dans l'épaisseur de la pédale de commande 2 et qui ont la même orientation angulaire. Ces extrémités sont retenues en place par une goupille 9, ou tout autre organe approprié, permettant leur rotation sur elles-mêmes.The ends 5 of the two brake arms 1 are bent towards one another and mounted to rotate on themselves inside bores 8 formed in the thickness of the control pedal 2 and which have the same orientation angular. These ends are retained in place by a pin 9, or any other suitable member, allowing them to rotate on themselves.

Le plan formé par les extrémités coudées 5 des deux bras de freinage est parallèle aux faces supérieure et inférieure de la pédale 2. Compte- tenu de leur inclinaison l'une par rapport à l'autre, les extrémités coudées 5 des deux bras de freinage 1 forment un V dont le sommet 0 est dirigé du côté opposé aux extrémités actives 6 de ces deux bras (voir figure 7). Bien entendu ce sommet est par ailleurs situé dans le plan perpendiculaire au ski qui passe par l'axe longitudinal médian XY de celui-ci.The plane formed by the bent ends 5 of the two braking arms is parallel to the upper and lower faces of the pedal 2. Given their inclination relative to each other, the bent ends 5 of the two braking arms 1 form a V whose apex 0 is directed on the side opposite the active ends 6 of these two arms (see FIG. 7). Of course this summit is also located in the plane perpendicular to the ski which passes through the median longitudinal axis XY thereof.

Il convient de noter que l'angle de coudage a des bras de freinage et l'orientation angulaire des alésages 8 prévus dans l'épaisseur de la pédale 2 sont tels que l'écartement des extrémités des patins de freinage puisse être modifié, par simple rotation des bras 1 sur eux-mêmes à l'intérieur des alésages 8, entre un écartement maximum L1 , correspondant à la position de travail de ces deux bras et une position d'écartement minimum L2 correspondant à la position de relèvement de ceux-ci au-dessus du ski, lorsque le frein est en attente de fonctionnement. Cet écartement minimum L2 est tel que les bras de freinage, et notamment leurs extrémités 6, se trouvent rétractés par rapport aux côtés latéraux du ski de façon à ne pas déborder par rapport à ceux-ci (voir figure 7).It should be noted that the bending angle has braking arms and the angular orientation of the bores 8 provided in the thickness of the pedal 2 are such that the spacing of the ends of the braking pads can be modified, by simple rotation of the arms 1 on themselves inside the bores 8, between a maximum spacing L1, corresponding to the working position of these two arms and a minimum spacing position L2 corresponding to the lifting position of these above the ski, when the brake is awaiting operation. This minimum spacing L2 is such that the braking arms, and in particular their ends 6, are retracted tees with respect to the lateral sides of the ski so as not to project beyond them (see FIG. 7).

Dans l'exemple représenté aux figures 1 à 7, il est prévu des organes élastiques de rappel qui tendent à faire tourner sur elles-mêmes, les extrémités coudées 5 des bras de freinage à l'intérieur des alésages 8, dans leur position correspondant à l'écartement minimum L2 des extrémités actives de ces mêmes bras. Ces organes élastiques peuvent consister en des tampons cylindriques 10 en caoutchouc, logés dans l'épaisseur de la pédale 2, et agissant chacun contre un méplat 11 prévu sur l'extrémité coudée 5 du bras de freinage correspondant. L'orientation angulaire de ce méplat est telle que celui-ci se trouve disposé tangentiellement à une génératrice du tampon élastique 10 correspondant lorsque le bras de freinage respectif 1 est dans sa position de rétraction (voir figure 4). Lorsque ce bras en est écarté, le méplat 11 peut comporter la position représentée à la figure 4a. Dans ce cas l'élasticité du tampon élastique tend à rappeler le bras correspondant dans sa position de rétraction.In the example shown in Figures 1 to 7, there are provided elastic return members which tend to rotate on themselves, the bent ends 5 of the braking arms inside the bores 8, in their position corresponding to the minimum spacing L2 of the active ends of these same arms. These elastic members may consist of cylindrical rubber pads 10, housed in the thickness of the pedal 2, and each acting against a flat 11 provided on the bent end 5 of the corresponding braking arm. The angular orientation of this flat is such that it is disposed tangentially to a generator of the corresponding elastic buffer 10 when the respective braking arm 1 is in its retracted position (see FIG. 4). When this arm is moved away from it, the flat 11 may include the position shown in FIG. 4a. In this case the elasticity of the elastic pad tends to return the corresponding arm to its retracted position.

Par ailleurs un autre ressort de rappel est prévu pour assurer le relèvement de la pédale 2 de commande dans la position représentée aux figures 1. 3 et 5. Ce ressort peut consister en un ressort de torsion 12 disposé autour de l'axe d'articulation 3 de cette pédale.Furthermore, another return spring is provided to raise the control pedal 2 in the position shown in FIGS. 1. 3 and 5. This spring may consist of a torsion spring 12 placed around the articulation axis. 3 of this pedal.

Dans la position de relèvement de la pédale de commande 2 du présent frein, les deux bras de freinage 1 se trouvent dirigés vers le bas comme représenté sur les figures 1, 3 et 5. Dans ces conditions les bras de freinage, et leurs extrémités actives 6, pénètrent dans la neige pour assurer le freinage désiré. Dans cette position, ce sont les côtés latéraux du ski qui empêchent que se produise la rétraction des extrémités actives 6 des bras de freinage sous l'action des organes élastiques de rappel constitués par les tampons cylindriques 10.In the position for raising the control pedal 2 of this brake, the two braking arms 1 are directed downward as shown in FIGS. 1, 3 and 5. Under these conditions the braking arms, and their active ends 6, enter the snow to ensure the desired braking. In this position, it is the lateral sides of the ski which prevent the retraction of the active ends 6 of the braking arms under the action of the elastic return members constituted by the cylindrical buffers 10.

Il faut observer que le pivotement de la pédale de commande 2 dans sa position de relèvement est limité par butée du chant 15 de cette pédale contre la platine 4. Or ce chant a une certaine inclinaison pour que la pédale 2 se trouve alors dans la position oblique représentée à la figure 5.It should be observed that the pivoting of the control pedal 2 in its raising position is limited by abutment of the edge 15 of this pedal against the plate 4. However, this edge has a certain inclination so that the pedal 2 is then in the position oblique shown in Figure 5.

Lorsque le skieur pose sa chaussure sur la pédale 2, pour procéder au montage de celle-ci dans la fixation correspondante, ceci provoque le pivotement de cette pédale dans le sens F autour de son axe 3, à l'encontre de l'action du ressort 12. Cette pédale entraîne alors les bras de freinage 1 dans son mouvement, ce qui assure le relèvement des extrémités actives 6 de ces deux bras au-dessus de la surface supérieure du ski.When the skier puts his shoe on the pedal 2, to mount it in the corresponding binding, this causes the pivoting of this pedal in the direction F around its axis 3, against the action of the spring 12. This pedal then drives the braking arms 1 in its movement, which ensures the raising of the active ends 6 of these two arms above the upper surface of the ski.

Cependant, tant que les patins de freinage 7 n'ont pas atteint le dessus du ski, les bords de celui-ci empêchent que puisse se produire la rétraction de ces patins de freinage.However, as long as the brake pads 7 have not reached the top of the ski, the edges of the ski prevent the retraction of these brake pads from occurring.

Mais dès que ces patins sont suffisamment relevés, les tampons élastiques 10 assurent la rotation des bras de freinage 1 sur eux-mêmes jusque dans leur position de rétraction représentée à la figure 7.But as soon as these pads are raised enough, the elastic buffers 10 ensure the rotation of the braking arms 1 on themselves as far as in their retraction position shown in FIG. 7.

Inversement, dès que la chaussure du skieur est soulevée de la pédale de commande 2, le ressort 3 provoque le relèvement de cette pédale et les patins de freinage 7 sont ainsi amenés en appui sur le ski. Ceci provoque la rotation des bras de freinage sur eux-mêmes à l'intérieur des paliers 8 prévus dans la pédale 2, jusqu'à ce que leurs patins de freinage présentent un écartement suffisant pour que ces bras puissent passer de part et d'autre des côtés latéraux du ski. Ainsi les patins de freinage 7 se trouvent amenés automatiquement dans leur position d'écartement maximum L1, qui est leur position de travail.Conversely, as soon as the skier's shoe is lifted from the control pedal 2, the spring 3 causes the lifting of this pedal and the brake pads 7 are thus brought to bear on the ski. This causes the braking arms to rotate on themselves inside the bearings 8 provided in the pedal 2, until their braking pads have sufficient spacing for these arms to pass on either side. lateral sides of the ski. Thus, the brake pads 7 are automatically brought into their maximum spacing position L1, which is their working position.

Comme on peut le constater, les mouvements d'écartement et de rapprochement des bras de freinage sont dus à la forme coudée de leurs extrémités 5 de commande et à l'orientation angulaire des alésages 8, ménagés à l'intérieur de la pédale 2, pour servir de paliers de rotation aux extrémités correspondantes de ces deux bras. Or ces mouvements s'effectuent sans frottement important des bras de freinage contre le ski ou contre des pièces annexes fixées sur celui-ci. De ce fait il suffit d'un ressort de rappel 12 de puissance relativement faible pour commander le déplacement de ces bras dans leur position active de travail. Ainsi, en position d'attente, la chaussure n'est pas amenée à subir une poussée verticale importante susceptible de perturber le déclenchement de la fixation de sécurité assurant la retenue de cette chaussure sur le ski.As can be seen, the spacing and approximation movements of the braking arms are due to the bent shape of their control ends 5 and to the angular orientation of the bores 8, formed inside the pedal 2, to serve as rotational bearings at the corresponding ends of these two arms. However, these movements are carried out without significant friction of the braking arms against the ski or against ancillary parts fixed on it. Therefore, a return spring 12 of relatively low power is sufficient to control the movement of these arms in their active working position. Thus, in the waiting position, the boot is not made to undergo a significant vertical thrust liable to disturb the triggering of the safety binding ensuring the retention of this boot on the ski.

Mais un autre avantage important de ce frein réside dans le fait que la structure de celui-ci est extrêmement simple. En effet les bras de freinage ne comportent pas une série de coudes successifs comme cela est le cas dans certains dispositifs antérieurs. Par ailleurs ces bras sont exclusivement portés par la pédale de commande qui s'articule directement sur le ski. La simplification de structure, qui en résulte a l'avantage d'entraîner une réduction sensible du prix de revient de l'ensemble.But another important advantage of this brake is that the structure of it is extremely simple. In fact, the braking arms do not comprise a series of successive bends, as is the case in certain prior devices. Furthermore, these arms are exclusively carried by the control pedal which is articulated directly on the ski. The resulting simplification of structure has the advantage of bringing about a significant reduction in the cost price of the assembly.

Un autre avantage encore du frein selon l'invention consiste en ce que celui-ci présente un encombrement extrêmement faible dans le sens de la hauteur. Ceci permet de le disposer sans inconvénient au-dessous de l'emplacement de la partie centrale de la chaussure correspondante.Yet another advantage of the brake according to the invention consists in that it has an extremely small size in the height direction. This allows it to be arranged without disadvantage below the location of the central part of the corresponding shoe.

Les figures 8 à 10 représentent une variante de la forme de réalisation décrite ci-dessus. Celle-ci s'en différencie uniquement par le fait que les organes élastiques de rappel des bras de freinage, dans leur position de rétraction, sont sup- ' primés et que le mouvement correspondant est alors commandé par une butée disposée au-dessus de la position de relèvement des patins de , freinage. Comme prévu dans l'exemple représenté, cette butée peut être avantageusement constituée par un autre élément d'équipement du ski correspondant, en l'occurrence la plaque' tournante 13 d'une talonnière de fixation 14.Figures 8 to 10 show a variant of the embodiment described above. It differs therefrom only in that the resilient members for returning the braking arms in their retracted position, are assumed 'winning and the corresponding movement is then controlled by a stop arranged above the lifting position of the brake pads. As provided in the example shown, this stop may advantageously be constituted by another element of equipment of the corresponding ski, in this case the turntable 13 of a fixing heel piece 14.

Si l'on fait abstraction de cette modification, l'ensemble de la structure du frein correspondant est la même que précédemment. C'est pourquoi lès différents organes de ce frein sont représentés par les mêmes chiffres de référence simplement affectés de l'indice « ".Leaving aside this modification, the entire structure of the corresponding brake is the same as before. This is why the various components of this brake are represented by the same reference numbers simply assigned the index "".

Dans cette variante, lors du rabattement de la pédale de commande 2a contre le ski, les patins de freinage 7a viennent buter contre la plaque tournante 13b. Ceci les arrête donc dans leur mouvement de relèvement alors que la pédale de commande 2a n'est pas encore complètement rabattue contre le ski.In this variant, during the folding of the control pedal 2a against the ski, the brake pads 7a abut against the turntable 13b. This therefore stops them in their raising movement while the control pedal 2a is not yet completely folded against the ski.

En conséquence la poursuite de ce rabattement provoque une rotation des extrémités coudées correspondantes des bras de freinage 1a jusque dans la position pour laquelle les patins 7a de ces bras se trouvent amenés en position de rétraction par rapport aux bords latéraux du ski (voir figure 10).Consequently, the continuation of this folding causes a rotation of the corresponding bent ends of the braking arms 1a until in the position for which the pads 7a of these arms are brought into the retraction position relative to the lateral edges of the ski (see FIG. 10). .

Les figures 11 à 13 représentent une autre forme de réalisation du frein à ski selon l'invention. Celle-ci se différencie de celle représentée aux figures 1 à 7 par une orientation différente des alésages ménagés dans l'épaisseur de la pédale de commande et qui servent de paliers de rotation aux extrémités coudées correspondantes des bras de freinage.Figures 11 to 13 show another embodiment of the ski brake according to the invention. This differs from that shown in FIGS. 1 to 7 by a different orientation of the bores made in the thickness of the control pedal and which serve as rotation bearings at the corresponding bent ends of the braking arms.

Cependant la structure générale de ce frein est la même que précédemment. Dans ces conditions ses divers organes constitutifs sont désignés par les mêmes chiffres de référence, simplement affectés de l'indice « b •.However, the general structure of this brake is the same as before. Under these conditions, its various constituent bodies are designated by the same reference numbers, simply assigned the index “b •.

Dans cette forme particulière de réalisation, le plan, formé par les extrémités coudées 5b des bras de freinage 1 b, est perpendiculaire aux faces supérieure et inférieure de la pédale de commande 2b. Par ailleurs le sommet 0 du V, formé par les axes de ces deux extrémités coudées, est dirigé vers le haut, et non plus du côté opposé aux patins de freinage (voir figure 12).In this particular embodiment, the plane, formed by the bent ends 5b of the braking arms 1b, is perpendicular to the upper and lower faces of the control pedal 2b. Furthermore, the top 0 of the V, formed by the axes of these two bent ends, is directed upwards, and no longer on the side opposite to the brake pads (see FIG. 12).

Cependant l'agencement est tel que dans la position de relèvement des bras de freinage 1b, correspondant au rabattement de la pédale de commande 2b contre le ski, les patins de freinage 7b présentent un écartement minimum grâce à quoi ils se trouvent alors rétractés par rapport aux côtés latéraux du ski (voir figure 11). Mais du fait de l'orientation angulaire des alésages 8b, prévus dans l'épaisseur de la pédale 2b, et du fait du coude des bras de freinage 1 b, le relèvement de la pédale de commande s'accompagne d'un écartement des patins de freinage 7b de part et d'autre du ski par rotation de ces bras dans les alésages correspondants.However, the arrangement is such that in the raising position of the braking arms 1b, corresponding to the folding of the control pedal 2b against the ski, the braking pads 7b have a minimum spacing whereby they are then retracted from on the lateral sides of the ski (see figure 11). But due to the angular orientation of the bores 8b, provided in the thickness of the pedal 2b, and due to the elbow of the braking arms 1b, the raising of the control pedal is accompanied by a spacing of the pads braking 7b on either side of the ski by rotation of these arms in the corresponding bores.

Dans cette forme de réalisation, le rappel des bras de freinage dans leur position de rétraction, représentée à la figure 11, peut être assuré soit par des organes élastiques, tels que les tampons cylindriques 10 prévus dans la forme de réalisation des figures 1 à 7, soit par une butée d'arrêt limitant le relèvement des patins de freinage, comme prévu dans la variante selon les figures 8 à 10.In this embodiment, the return of the braking arms to their retraction position, shown in FIG. 11, can be ensured either by elastic members, such as the cylindrical buffers 10 provided in the embodiment of FIGS. 1 to 7 , or by a stop limiting the raising of the brake shoes, as provided in the variant according to FIGS. 8 to 10.

Cependant le frein selon l'invention n'est pas limité aux seuls exemples qui ont été décrits ci-dessus à simple titre indicatif. Ainsi le plan formé par les extrémités coudées des bras de freinage pourrait être incliné par rapport aux faces supérieure et inférieure de la pédale de commande au lieu d'être parallèle ou perpendiculaire à celle-ci, le sommet du V formé par les axes de ces extrémités serait alors dirigé à la fois du côté opposé aux patins de freinage et vers le haut, c'est-à-dire du côté opposé au ski.However, the brake according to the invention is not limited to the examples which have been described above for information only. Thus the plane formed by the bent ends of the braking arms could be inclined relative to the upper and lower faces of the control pedal instead of being parallel or perpendicular to it, the top of the V formed by the axes of these ends would then be directed both on the side opposite to the brake pads and upwards, that is to say on the side opposite to the ski.

Par ailleurs au lieu de prévoir des organes élastiques de rappel ou une butée d'arrêt pour commander la rétraction des bras de freinage 6, il est possible de s'en abstenir en laissant jouer à la chaussure du skieur le rôle d'une butée provoquant ce mouvement. Dans ce cas lorsque la chaussure se pose sur le ski elle s'applique en premier contre la pédale de commande et provoque le relèvement des patins de freinage. Ensuite, en fin de course de relèvement, ces patins sont amenés à buter contre cette chaussure qui est presque à plat sur le ski. Ceci provoque donc la rétraction des patins de freinage au-dessus du ski. Ainsi la chaussure joue alors le même rôle de butée que la plaque tournante 13 de la talonnière 14 représentée aux figures 8 à 10.Furthermore, instead of providing elastic return members or a stop for controlling the retraction of the braking arms 6, it is possible to refrain from doing so by allowing the skier's shoe to play the role of a stop causing this movement. In this case, when the boot lands on the ski, it is applied first against the control pedal and causes the brake pads to rise. Then, at the end of the raising race, these skates are brought to abut against this shoe which is almost flat on the ski. This therefore causes the brake pads to retract above the ski. Thus, the shoe then plays the same role of abutment as the turntable 13 of the heel piece 14 shown in FIGS. 8 to 10.
