Abstract

A pivotal control flap carried by the top section of one ski-braking arm is connected to an identical flap carried by the other braking arm by means of a top arcuate member. Each flap has two separate bores forming swivel-bearings respectively for the top section of the corresponding arm and for the respective leg of the arcuate connecting member. The angle made by the bores with respect to each other is such that the pivotal displacement of the two flaps under the pressure of the ski boot produces a movement of relative inward withdrawal of the bottom sections of the braking arms when they are in the raised position.

Description

La présente invention concerne les freins à ski comportant deux bras de freinage, disposés de part et d'autre du ski, et qui sont soumis à l'action d'un ressort tendant à les rappeler dans leur position active.The present invention relates to ski brakes comprising two braking arms, arranged on either side of the ski, and which are subjected to the action of a spring tending to return them to their active position.

Dans les freins à ski de ce type, chaque bras de freinage peut être avantageusement constitué par un fil métallique convenablement coudé pour former un tronçon inférieur portant un patin de freinage, un tronçon intermédiaire monté à pivotement sur le ski et un tronçon supérieur soumis à la pression de la chaussure lorsque celle-ci est en place.In ski brakes of this type, each braking arm may advantageously consist of a metal wire suitably bent to form a lower section carrying a brake shoe, an intermediate section pivotally mounted on the ski and an upper section subjected to the shoe pressure when it is in place.

En général l'extrémité supérieure des deux bras de freinage ainsi constitués prote une pédale de commande, ou un organe similaire, sur lequel la chaussure vient s'appuyer Lors de sa mise en place sur le ski. Ainsi la chaussure provoque automatiquement le pivotement des bras de freinage dans leur position escamotée de repos ; mais, sous l'effet du ressort de rappel, ceux-ci se déploient immédiatement dès l"échappement de la chaussure.In general, the upper end of the two braking arms thus formed protects a control pedal, or a similar member, on which the boot comes to rest When it is put in place on the ski. Thus the shoe automatically causes the brake arms to pivot into their retracted rest position; but, under the effect of the return spring, these are deployed immediately as soon as the shoe escapes.

Certains de ces freins à ski comportent des moyens assurant la rétraction des patins de freinage en position escamotée, de façon que ceux-ci ne débordent pas sur les côtés du ski.Some of these ski brakes include means ensuring the retraction of the brake pads in the retracted position, so that they do not overflow on the sides of the ski.

Ainsi dans le brevet français 76 11752 (publication 2.308.389), la rétraction des bras de freinage en position escamotée est obtenue par pression sur une plaquette défor- mable ou quadrilatère articulé, disposé sous l'emplacement de la chaussure de façon à être aplati par celle-ci lors de sa mise en place. L'agencement esttel que l'apatissement de cette plaquette ou de ce quadrilatère articulé provoque alors le rapprochement des deux bras de freinage, après que ceux-ci aient été relevés en position d'eacamotage.Thus, in the French patent 76 11752 (publication 2308389), the retraction of the braking arm in the retracted position is obtained by pressing a plate fin or - mable or articulated quadrilateral disposed under the location of the shoe so as to be flattened by it during its installation. The arrangement is such that the flattening of this plate or of this articulated quadrilateral then brings the two braking arms closer together, after they have been raised to the retractable position.

Cependant, si la plaquette de commande est une lame cintrée, celle-ci exerce une pression élevée sous la chaussure. Or, ceci est de nature à perturber les conditions de libération de la chaussure lors du déclenchement de la fixation de retenue de celle-ci sur le ski. Par ailleurs, si la plaquette de commande consiste en un quadrilatère articulé, le système prévu est particulièrement compliqué et coûteux. De plus, celui-ci est peu fiable d'autant plus que son fonctionnement est sensible au gel.However, if the control plate is a curved blade, this exerts a high pressure under the shoe. However, this is likely to disrupt the conditions for releasing the boot when the retaining binding is released on the ski. Furthermore, if the control plate consists of an articulated quadrilateral, the system provided is particularly complicated and expensive. In addition, it is unreliable especially since its operation is sensitive to frost.

Dans le brevet français 75 34137 (publication 2.330.419), la rétraction des bras de freinage est obtenue par l'action d'une ou plusieurs rampes pouvant être portées par une pédale auxiliaire. Mais, là encore, les solutions prévues;ne donnent pas satisfaction. En effet, la rétraction des bras étant obtenue par déformation du fil qui les constitue, il est nécessaire d'exercer une force très élevée à cet effet. De plus, ce système crée également des contraintes parasites perturbant les conditions de libération de la chaussure en cas de déclenchement de la fixation.In French patent 75 34137 (publication 2.330.419), the retraction of the braking arms is obtained by the action of one or more ramps which can be carried by an auxiliary pedal. But, here again, the solutions provided; are not satisfactory. Indeed, the retraction of the arms being obtained by deformation of the wire which constitutes them, it is necessary to exert a very high force for this purpose. In addition, this system also creates parasitic stresses disrupting the conditions of release of the shoe in the event of triggering of the binding.

D'autre part, pour éviter un trop grand encombrement, il est nécessaire de limiter la hauteur des rampes de commande, ce qui par conséquent limite l'amplitude de rétraction des bras de freinage.On the other hand, to avoid too much space, it is necessary to limit the height of the control ramps, which consequently limits the amplitude of retraction of the braking arms.

Selon une autre solution encore, la rétraction d'un bras de freinage peut être obtenue en faisant pivoter celui-ci dans un palier dont l'axe, situé dans un plan transver, sal au ski, est incliné par rapport à la face supérieure de celui-ci (figure 11 du brevet français 73 17074 : publication 2.228.506). Un tel système a l'avantage d'être extrêmement simple. Mais par contre, il a pour inconvénient que la moindre déformation du bras de freinage peut provoquer son frottement et éventuellement son blocage sur la tranche du ski, puisque la rétraction du bras s'effectue en même temps que son relevage. Un autre inconvénient réside dans le fait que pour obtenir une rétraction suffisamment importante, il est nécessaire que le palier d'articulation soit situé relativement haut, ce qui est inacceptable si le frein est placé sous la chaussure.According to yet another solution, the retraction of a braking arm can be obtained by pivoting the latter in a bearing whose axis, located in a transverse plane, sal to the ski, is inclined relative to the upper face of this one (figure 11 of French patent 73 17074 : publication 2.228.506). The advantage of such a system is that it is extremely simple. However, it has the disadvantage that the slightest deformation of the braking arm can cause it to rub and possibly block on the edge of the ski, since the retraction of the arm is carried out at the same time as its lifting. Another disadvantage lies in the fact that to obtain a sufficient retraction important, it is necessary that the articulation bearing is located relatively high, which is unacceptable if the brake is placed under the shoe.

D'une façon générale la plupart des systèmes proposés jusqu'ici pour réaliser la rétraction des bras de freinage présentent des inconvénients importants. C'est la raison pour laquelle la présente invention a pour but de réaliser un frein à ski dans lequel la rétraction des bras de freinage est obtenue au moyen d'un système simple, fiable et peu coûteux, ce système étant par ailleurs facile à manoeuvrer et exerçant sous la chaussure une poussée parasite négligeable.In general, most of the systems hitherto proposed for retracting the braking arms have significant drawbacks. This is the reason why the present invention aims to produce a ski brake in which the retraction of the braking arms is obtained by means of a simple, reliable and inexpensive system, this system being moreover easy to maneuver. and exerting a negligible parasitic thrust under the shoe.

Ce frein à ski est essentiellement caractérisé en ce que le tronçon supérieur de chacun de ses bras de freinage porte un volet pivotant de commande relié au volet du tronçon supérieur de l'autre bras par un arceau supérieur et en ce que chacun de ces volets présentedeux alésages distincts servant de paliers d'articulation respectivement au tronçon supérieur du bras correspondant et à la branche respective de l'arceau supérieur de liaison, ces alésages formant entre eux un angle tel que le pivotement des deux volets autour des branches de l'arceau supérieur de raison, sous l'effet de la pression de la chaussure, détermine un rapprochement des tronçons inférieurs des bras de freinage.This ski brake is essentially characterized in that the upper section of each of its braking arms carries a pivoting control flap connected to the flap of the upper section of the other arm by an upper hoop and in that each of these flaps has two separate bores serving as articulation bearings respectively for the upper section of the corresponding arm and for the respective branch of the upper connecting arch, these bores forming an angle between them such that the pivoting of the two flaps around the branches of the upper arch reason, under the effect of the pressure of the shoe, determines a bringing together of the lower sections of the braking arms.

Ainsi les patins de freinage de ces bras se trouvent automatiquement rétractés lorsqu'ils sont en position d'escamotage, ce qui évite leur débordement par rapport aux c8tés du ski.Thus the brake pads of these arms are automatically retracted when they are in the retracted position, which prevents them from overflowing relative to the sides of the ski.

Ce frein à ski comporte deux bras de freinage 1 disposés symétriquement par rapport au plan longitudinal médian du ski S. Chacun de ces bras est coudé dans un plan de manière à présenter un tronçon inférieur 2 portant un patin de freinage 3, un tronçon intermédiaire 4 monté à pivotement dans un palier 5, et un tronçon supérieur 6 de commande. Les deux paliers 5 sont portés par une platine 7 servant d'embase pour le montage de l'ensemble sur le ski S au moyen de vis 8. Ces deux paliers sont disposés de façon à matérialiser en quelque sorte un axe transversal XY pour le pivotement des deux bras de freinage 1. Cependant il convient de noter que les tronçons intermédiaires 4 de ceux-ci possèdent un certain jeu à l'intérieur de ces paliers.This ski brake comprises two braking arms 1 arranged symmetrically with respect to the median longitudinal plane of the ski S. Each of these arms is bent in a plane so as to have a lower section 2 carrying a braking pad 3, an intermediate section 4 pivotally mounted in a bearing 5, and an upper control section 6. The two bearings 5 are carried by a plate 7 serving as a base for mounting the assembly on the ski S by means of screws 8. These two bearings are arranged so as to somehow materialize a transverse axis XY for pivoting of the two braking arms 1. However, it should be noted that the intermediate sections 4 of these have a certain clearance inside these bearings.

Le tronçon supérieur 6 de chaque bras de freinage porte un volet pivotant de commande 9 et les deux volets ainsi prévus sont reliés par un arceau supérieur 10, en fil métallique, de même que les bras de freinage 1.The upper section 6 of each braking arm carries a pivoting control flap 9 and the two flaps thus provided are connected by an upper arch 10, made of metal wire, as are the braking arms 1.

Chacun des volets 9 présente deux alésages distincts 11 et 12 servant de paliers d'articulation, respectivement à l'extrémité du tronçon supérieur du bras correspondant et à la branche respective de l'arceau de liaison 10. Or, les axes de ces alésages ne sont pas dans le prolongement l'un de l'autre ni parallèles. En effet ils forment entre eux un angle tel que le rabattement à plat des deux volets 9 contre le ski, par pivotement autour de la branche de l'arceau supérieur de liaison 10, détermine un rapprochement des patins de freinage 3 par débattement des tronçons intermédiaires 4 des bras 1 à l'intérieur des paliers 5.Each of the flaps 9 has two separate bores 11 and 12 serving as articulation bearings, respectively at the end of the upper section of the corresponding arm and at the respective branch of the connecting arch 10. However, the axes of these bores do not are not in the extension one on the other nor parallel. Indeed, they form an angle between them such that the flat folding of the two flaps 9 against the ski, by pivoting around the branch of the upper link arch 10, determines a bringing together of the braking pads 3 by movement of the intermediate sections 4 of the arms 1 inside the bearings 5.

Le rappel des bras pivotants 1 dans leur position active de freinage est assuré par un ressort hélicoïdal 13 de traction dont une extrémité est attachée sur le coude de l'arceau supérieur de liaison 10, cependant que son extrémité opposée est accrochée à un axe fixe 14 porté par la platine 7 de montage.The pivoting arms 1 are returned to their active braking position is provided by a helical tension spring 13, one end of which is attached to the elbow of the upper link arch 10, while its opposite end is attached to a fixed axis 14 carried by the mounting plate 7.

A l'intérieur de ce ressort est disposée une tige 15 dont la/longueur est telle que celle-ci serve de butée limitant le déploiement des bras pivotants dans la position voulue pour le freinage.Inside this spring is arranged a rod 15 whose / length is such that it serves as a stop limiting the deployment of the pivoting arms in the desired position for braking.

En effet, en fin de déploiement de ces bras, l'arceau supérieur de liaison 10 vient en appui contre l'extrémité correspondante de la tige 15 tandis que l'extrémité opposée de celle-ci bute contre l'axe fixe 14. Ceci réalise donc un moyen très simple de limitation du déploiement des bras de freinage et ce moyen est très efficace puisque la tige 15 constitue en quelque sorte un arc-boutant entre l'arceau supérieur de liaison 10 et le ski.Indeed, at the end of deployment of these arms, the upper link arch 10 comes to bear against the corresponding end of the rod 15 while the opposite end of the latter abuts against the fixed axis 14. This achieves therefore a very simple means of limiting the deployment of the braking arms and this means is very effective since the rod 15 constitutes in a way a flying buttress between the upper link arch 10 and the ski.

Dans la position active des bras de freinage, les patins de freinage sont disposés de part et d'autre des chants du. ski comme représenté aux figures 1 et 2. Quant aux deux volets de commande 9 ils sont alors légèrement relevés vers l'extérieur.In the active position of the brake arms, the brake pads are arranged on either side of the edges of the. ski as shown in FIGS. 1 and 2. As for the two control flaps 9, they are then slightly raised towards the outside.

Lorsque la chaussure est mise en place, sa semelle vient s'appliquer sur ces deux volets ce qui provoque tout d'abord le pivotement des bras de freinage dans le sens de la flèche F par rotation des tronçons intermédiaires 4 à l'intérieur des paliers 5. Ce pivotement se poursuit jusqu'à ce que l'arceau supérieur de liaison 10 vienne en butée contre le dessus du ski. Les patins de freinage 3 se trouvent alors relevés au-dessus du niveau de la surface supérieure du ski.When the shoe is in place, its sole is applied to these two flaps which first of all causes the pivoting of the braking arms in the direction of arrow F by rotation of the intermediate sections 4 inside the bearings 5. This pivoting continues until the upper link arch 10 abuts against the top of the ski. The brake pads 3 are then raised above the level of the upper surface of the ski.

Dans cette position illustrée par la figure 3, les deux volets 9 continuent à être relevés vers l'extérieur et à former un dièdre comme représenté à la figure 6. Cependant la pression de la chaussure, qui continue à s'exercer sur ces deux volets, les fait pivoter dans le sens des flèches F1 et F2, par articulation autour des branches de l'arceau supérieur de liaison 10, jusqu'à ce que ces volets viennent se placer à plat sur le ski comme représenté à la figure 7.In this position illustrated in FIG. 3, the two flaps 9 continue to be raised towards the outside and to form a dihedral as shown in FIG. 6. However, the pressure of the shoe, which continues to be exerted on these two flaps , rotates them in the direction of arrows F1 and F2, by articulation around the branches of the upper link arch 10, until these flaps are placed flat on the ski as shown in FIG. 7.

¡Or le mouvement de pivotement de chacun de ces volets a pour effet d'exercer une traction vers l'intérieur sur le bras de freinage correspondant. Ceci provoque donc la rétraction des patins de freinage dans la position représentée à la figure 4, position pour laquelle ces patins se trouvent en retrait par rapport aux chants du ski.¡However, the pivoting movement of each of these components has the effect of exerting an inward traction on the corresponding braking arm. This therefore causes the brake pads to retract into the position shown in FIG. 4, the position for which these pads are set back relative to the edges of the ski.

Le mouvement particulier de débattement accompli alors par les deux bras de freinage ressort très clairement d'une comparaison des figures 3 et 4. Bien entendu ce mouvement est rendu possible par le fait que les tronçons intermédiaires 4 possèdent un certain jeu à l'intérieur des paliers 5.The particular movement of travel then accomplished by the two braking arms is very clear from a comparison of FIGS. 3 and 4. Of course this movement is made possible by the fact that the intermediate sections 4 have a certain play inside the bearings 5.

De plus, ce mouvement s'accompagne d'un léger déplacement de l'arceau de liaison 10 contre le ski à l'encontre de l'action du ressort 13. De ce fait, lorsque la chaussure se dégage et cesse d'appuyer sur les volets 9, la traction exercée par le ressort 13 provoque d'abord le relèvement des volets et par suite, l'écartement des patins de freinage qui peuvent alors passer de part et d'autre du ski pour pivoter dans leur position de travail.In addition, this movement is accompanied by a slight displacement of the connecting arch 10 against the ski against the action of the spring 13. As a result, when the boot comes off and stops pressing the flaps 9, the traction exerted by the spring 13 first causes the flaps to be raised and consequently the spacing of the brake pads which can then pass on either side of the ski to pivot in their working position.

La décomposition des mouvements des bras de freinage en deux temps est nécessaire pour éviter tout risque d'accrochage de ces bras contre les côtés du ski lors de leur déploiement ainsi que lors de leur relèvement.The breakdown of the braking arm movements in two stages is necessary to avoid any risk of hooking these arms against the sides of the ski during their deployment as well as during their lifting.

Le principal avantage du frein à ski selon l'invention réside dans la simplicité et l'efficacité des moyens prévus pour assurer la rétraction des patins de freinage dans leur position escamotée. De plus, dans le cas présent, cette rétraction nécessite un effort moindre que dans le cas où elle est obtenue par rabattement d'une pédale unique de commande pivotant autour d'un axe transversal. En effet dans le frein à ski selon l'invention cette rétraction est obtenue par le rabattement des deux volets 9 pivotant autour de deux axes s'étendant dans une direction longitudinale. Ce rabattement nécessite donc un effort moindre et les forces exercées sont beaucoup mieux réparties que dans le cas d'un appui sur une pédale unique. Or ceci facilite la mise en place de la chaussure dans la fixation du ski correspondante du fait même que le rabattement final des deux volets de commande est plus facile à réaliser.The main advantage of the ski brake according to the invention lies in the simplicity and efficiency of the means provided for ensuring the retraction of the brake pads in their retracted position. In addition, in the present case, this retraction requires less effort than in the case where it is obtained by folding down a single control pedal pivoting about a transverse axis. Indeed, in the ski brake according to the invention, this retraction is obtained by the folding of the two flaps 9 pivoting around two axes extending in a longitudinal direction. This folding down therefore requires less effort and the forces exerted are much better distributed than in the case of pressing on a single pedal. However, this facilitates the installation of the boot in the binding of the corresponding ski, because the final folding of the two control flaps is easier to achieve.
