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.

Plus particulièrement, l'invention se rapporte à un frein à ski comportant deux bras de freinage disposés symétriquement de part et d'autre des côtés latéraux du ski et dont chacun est coudé pour présenter un tronçon inférieur portant à son extrémité inférieure un patin de freinage, un . tronçon intermédiaire monté à pivotement avec un certain jeu dans un palier transversal fixé sur le ski et un tronçon supérieur soumis à la pression d'une chaussure lorsque celle-ci est en place sur le ski, le pivotement du tronçon inférieur jusque dans le plan supérieur du ski, suivi de son effacement vers l'intérieur dans ce plan au-dessus du ski est réalisé par rabattement du tronçon supérieur par la chaussure vers ledit plan suivi d'une portion de ce tronçon supérieur, le rappel des bras de freinage dans leur position active étant assuré par un ressort hélicoïdal attaché sur le dessus du ski.More particularly, the invention relates to a ski brake comprising two braking arms arranged symmetrically on either side of the lateral sides of the ski and each of which is bent to present a lower section carrying at its lower end a brake shoe , a . intermediate section pivotally mounted with a certain clearance in a transverse bearing fixed on the ski and an upper section subjected to the pressure of a boot when the latter is in place on the ski, the pivoting of the lower section into the upper plane of the ski, followed by its erasure inwardly in this plane above the ski is produced by folding the upper section by the boot towards said plane followed by a portion of this upper section, the return of the braking arms in their active position being ensured by a helical spring attached to the top of the ski.

Une forme de réalisation d'un frein à ski du genre rappelé ci-dessus est notamment décrite dans le brevet français FR-A-2 452 300 au nom de la demanderesse. Dans cette réalisation, les deux extrémités des bras pivotants opposés à leurs parties actives sont reliées directement l'une à l'autre par une articulation ou une zone flexible de liaison. Une pédale de commande s'articule sur les parties de ces bras située entre ce point de liaison et leur axe de pivotement, et ce, autour de deux axes inclinés en sens inverse par rapport à une ligne transversale au ski, de façon qu'après le relèvement des parties actives des bras de freinage sous l'effet de la pression de la chaussure de ski sur leurs extrémités opposées, le rabattement de la pédale de commande contre le ski provoque un rapprochement des parties actives des bras de freinage au-dessus du ski.An embodiment of a ski brake of the kind mentioned above is described in particular in French patent FR-A-2 452 300 in the name of the applicant. In this embodiment, the two ends of the pivoting arms opposite their active parts are connected directly to each other by a joint or a flexible connection zone. A control pedal is articulated on the parts of these arms situated between this connection point and their pivot axis, and this, around two axes inclined in opposite directions with respect to a transverse line to the ski, so that after the raising of the active parts of the braking arms under the effect of the pressure of the ski boot on their opposite ends, the folding of the control pedal against the ski causes the active parts of the braking arms to come together above the ski.

D'une façon plus particulière, le frein à ski selon le brevet français FR-A-2 452 300 met en oeuvre un étrier ou une pédale de commande centrale dont les extrémités sont fixées sur des manchons montés rotatifs autour des extrémités correspondantes des bras pivotants, ceux-ci étant articulés au centre autour d'un axe commun. Or une telle réalisation si elle permet d'obtenir une rétraction des patins de freinage en position escamotée de façon que ceux-ci ne débordent pas sur les côtés du ski, présente pour sa réalisation pratique certaines difficultés en raison notamment de l'utilisation d'un axe d'articulation entre les deux tronçons supérieurs des bras. Par ailleurs dans le frein à ski selon ce brevet antérieur, c'est un ressort central qui fait ouvrir les bras latéraux du frein, ces derniers en prenant appui sur les paliers s'écartant alors comme une paire de ciseaux. Il convient donc dans ce cas d'exercer sur la pédale fixée à la partie supérieure du frein à ski un effort relativement important.More specifically, the ski brake according to French patent FR-A-2 452 300 implements a caliper or a central control pedal, the ends of which are fixed on sleeves mounted to rotate around the corresponding ends of the pivoting arms. , these being articulated in the center around a common axis. However, such an embodiment if it makes it possible to obtain a retraction of the brake pads in the retracted position so that they do not overflow on the sides of the ski, presents for its practical realization certain difficulties due in particular to the use of an axis of articulation between the two upper sections of the arms. Furthermore, in the ski brake according to this prior patent, it is a central spring which causes the lateral arms of the brake to open, the latter being supported on the bearings which then move apart like a pair of scissors. It is therefore appropriate in this case to exert on the pedal fixed to the upper part of the ski brake a relatively large force.

La présente invention concerne un frein à ski qui apporte à une disposition générale du genre rappelé ci-dessus des perfectionnements particulièrement utiles en raison des contraintes et des conditions d'utilisation sévères d'un tel frein à ski. Notamment les dispositions de l'invention permettent d'assurer la commande du pivotement et la rétraction des bras latéraux du frein avec un effort moindre, l'action étant exercée sur ceux-ci en deux endroits distincts en une position médiane sur la longueur de ces bras. En outre chaque branche du frein étant réalisée de manière indépendante en deux tronçons distincts, les dispositions préconisées permettent d'assurer une sensible démultiplication de l'effort à exercer sur les bras.The present invention relates to a ski brake which brings to a general arrangement of the kind mentioned above improvements which are particularly useful because of the constraints and severe conditions of use of such a ski brake. In particular, the provisions of the invention make it possible to control the pivoting and the retraction of the lateral arms of the brake with less effort, the action being exerted on them in two distinct places in a median position along the length of these arms. In addition, each branch of the brake being produced independently in two distinct sections, the recommended arrangements make it possible to ensure a significant reduction in the force to be exerted on the arms.

Selon l'invention le frein à ski considéré se caractérise en ce que chaque tronçon supérieur d'un bras de freinage porte à son extrémité supérieure un volet latéral pivotant de commande, les deux volets étant reliés par un arceau supérieur médian et continu, en ce que chaque tronçon supérieur s'étend dans une direction sensiblement opposée à celle des tronçons inférieurs et en ce que son extrémité supérieure se termine dans le volet latéral pivotant correspondant, les deux volets prolongeant chaque tronçon supérieur, et en ce que chacun de ces volets présente deux alésages borgnes et opposés recevant respectivement du côté de chaque bras l'extrémité supérieure du tronçon supérieur et l'extrémité inférieure de l'arceau, ces alésages formant un angle l'un par rapport à l'autre et servant de palier d'articulation respectivement pour le tronçon supérieur et l'arceau, l'angle des axes des alésages d'un même volet étant tels que le rabattement à plat du volet contre le ski par pivotement autour de la branche de l'arceau supérieur provoque un rapprochement du patin de freinage correspondant vers l'axe médian du ski et le ressort hélicoïdal étant un ressort de traction attaché directement à l'arceau supérieur.According to the invention, the ski brake in question is characterized in that each upper section of a braking arm carries at its upper end a pivoting lateral control flap, the two flaps being connected by a median and continuous upper arch, in this that each upper section extends in a direction substantially opposite to that of the lower sections and in that its upper end ends in the corresponding pivoting side flap, the two flaps extending each upper section, and in that each of these flaps has two blind and opposite bores receiving respectively on the side of each arm the upper end of the upper section and the lower end of the arch, these bores forming an angle with respect to each other and serving as an articulation bearing respectively for the upper section and the arch, the angle of the axes of the bores of the same flap being such that the flat folding of the flap against the ski by pivoting automatically Our branch of the upper arch causes the corresponding brake shoe to move towards the median axis of the ski and the helical spring being a tension spring attached directly to the upper arch.

Ce frein à ski comporte deux bras de freinage 1 disposés systématiquement 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 systematically arranged 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 line with each other or 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 brake 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 coudé 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 return of the pivoting arms 1 to their active braking position is ensured by a helical tension spring 13, one end of which is attached to the bend 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 therefore achieves 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 Figures 1 and 2. As for the two control flaps 9 they are then slightly raised outwards.

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.In this position illustrated by FIG. 3, the two flaps 9 continue to be raised towards the outside and to form a dihedral as shown in FIG. 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.However, the pressure of the shoe, which continues to be exerted on these two flaps, makes them pivot in the direction of the 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 Figure 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 decomposition of the movements of the braking arms in two stages is necessary to avoid any risk of these arms hooking 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 this case, this retraction requires less effort than in the case where it is obtained by folding down a single control pedal pivoting about an axis. transverse. In fact, 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.
