Abstract

The ski brake consists of a plate (3) with two arms (1) which pivot about a spindle (4). The skier's boot is normally pressed over the plate so that the arms lie above the level of the ski under normal use. If for any reason the ski becomes detached from the boot a torsion spring swings the arms downwards into the snow to bring the ski to rest. In order to prevent the arms from projecting over the edges of the ski during normal use, a guide (8) with inclined surfaces is fitted to the plate. As the plate is swung towards the ski, the guide is pushed into a recess in the plate and its inclined surfaces press the arms inwards over the upper surface of the ski so that they lie within the ski edges.

Description

La présente invention a pour but de réaliser un frein pour ski du type à bras rentrants, muni d'un dispositif de commande à plans inclinés actionné par le poids du skieur.The object of the present invention is to provide a ski brake of the retractable arm type, provided with an inclined plane control device actuated by the weight of the skier.

On sait que de nombreux freins pour ski ont été jusqu'ici proposés, qui permettent d'arrêter automatiquement le ski dès que pour une raison quelconque celui-ci doit se détacher de la chaussure de l'utilisateur, ces freins opérant en général l'abaissement, au-dessous de la face inférieure du ski, d'une paire de bras qui en pénétrant dans la neige assurent le freinage de ce ski, et ce même sur des pentes accentuées.We know that many ski brakes have been proposed so far, which allow to automatically stop the ski as soon as for some reason it must detach from the shoe of the user, these brakes generally operating the lowering, below the underside of the ski, of a pair of arms which, penetrating into the snow, ensure the braking of this ski, even on steep slopes.

Cependant les dispositifs de freinage actuellement en usage présentent l'inconvénient qu'à la position de repos les bras font quelque peu saillie latéralement sur les côtés du ski, en provoquant des contraintes dans l'utilisation de celui-ci, en particulier dans le slalom ou de manière générale lorsque le ski se déplace en position assez inclinée par rapport à la surface enneigée.However, the braking devices currently in use have the disadvantage that in the rest position the arms protrude somewhat laterally on the sides of the ski, causing constraints in the use thereof, in particular in the slalom or generally when the ski is moving in a fairly inclined position relative to the snow-covered surface.

Par contre avec l'adoption de la présente invention, en position de ski chaussé tout le dispositif rentre presque complètement dans l'étendue de la largeur du ski, en annulant donc toute possibilité de contact dudit dispositif avec la neige, avec des avantages considérables pour l'utilisateur aussi bien sur le plan psychologique que sur le plan de la réalité.On the other hand, with the adoption of the present invention, in the ski-in position, the whole device almost completely falls within the width of the ski, thus eliminating any possibility of contact of said device with the snow, with considerable advantages for the user both psychologically and in terms of reality.

Le dispositif suivant l'invention prévoit que les bras de freinage sont portés par une platine basculant sur un pivot passant dans la semelle de base qui soutient l'attache arrière du ski, cette platine mobile comportant dans son étendue une plaquette profilée, munie de deux coins faisant saillie vers l'intérieur de ladite platine et qui sous l'action de compression de la chaussure du skieur déplace les bras de freinage vers l'intérieur de la surface supérieure du corps du ski, grâce aux plans inclinés présentés par les coins dont elle est dotée, en agissant alors à l'encontre d'un ressort de rappel. .The device according to the invention provides that the braking arms are carried by a plate tilting on a pivot passing through the base plate which supports the rear attachment of the ski, this mobile plate comprising in its extent a profiled plate, provided with two wedges protruding towards the inside of said plate and which under the compression action of the skier's shoe displaces the braking arm towards the inside of the upper surface of the ski body, thanks to the inclined planes presented by the corners with which it is provided, while acting against a return spring. .

Ce dernier tend à ramener les bras à la position élargie dès que la platine mobile, à nouveau libérée par la chaussure de l'utilisateur, revient à se soulever sous l'action d'un second organe élastique.The latter tends to bring the arms back to the enlarged position as soon as the movable plate, again released by the user's shoe, comes back up under the action of a second elastic member.

L'invention va maintenant être ci-après décrite plus en détail, avecl'aide des planches de dessin annexées, dans lesquelles :

  • La fig. 1 est la vue de côté d'un ski avec la platine mobile du frein en position soulevée.
  • La fig. 2 est une vue en plan de ce ski.
  • La fig. 3 montre en vue de dessous la platine mobile, la plaquette de commande ayant été démontée.
  • Les fig. 4, 5 et 6 représentent respectivement en élévation par l'avant, en plan et par côté la plaquette de commande à l'état isolé.
  • Les fig. 7 et 8 montrent en élévation par l'arrière, aux deux positions de travail du frein, la platine mobile avec la plaquette de commande montée.
The invention will now be described in more detail below, with the help of the attached drawing boards, in which:
  • Fig. 1 is the side view of a ski with the movable plate of the brake in the raised position.
  • Fig. 2 is a plan view of this ski.
  • Fig. 3 shows a view from below of the mobile stage, the control plate having been dismantled.
  • Figs. 4, 5 and 6 represent respectively in elevation from the front, in plan and by side the control board in the isolated state.
  • Figs. 7 and 8 show in elevation from the rear, at the two working positions of the brake, the movable plate with the mounted control plate.

Le frein suivant l'invention comprend deux bras 1 et 2 (fig.l et 2) montés sur une platine 3 qui bascule sur la charnière 4 retenue en place sur la semelle fixe 5, laquelle est rendue solidaire du ski 6 par des mâchoires latérales 7.The brake according to the invention comprises two arms 1 and 2 (fig.l and 2) mounted on a plate 3 which switches on the hinge 4 retained in place on the fixed sole 5, which is made integral with the ski 6 by lateral jaws 7.

La plaquette mobile 8 qui à la position soulevée de la platine 3 fait saillie par rapport à celle-ci sous l'action d'un ressort, rentre à l'intérieur de ladite platine lorsque le ski est chaussé par l'utilisateur, en faisant rentrer les deux bras 1 et 2 à la position dessinée en trait plein. En fig. 3 on voit la platine mobile 3 vue par dessous avec la plaquette 8 démontée.The movable plate 8 which in the raised position of the plate 3 protrudes relative to the latter under the action of a spring, enters the interior of said plate when the ski is put on by the user, making return them two arms 1 and 2 in the position drawn in solid lines. In fig. 3 shows the movable plate 3 seen from below with the plate 8 removed.

Les bras 1 et 2 ont été dessinés en trait plein à la position élargie et en tracé interrompu à la position resserrée.Arms 1 and 2 were drawn in solid lines in the extended position and in broken lines in the constricted position.

Ils sont soumis à l'action du ressort 9 qui tend à les écarter tandis que les ressorts 10 et 11 tendent à rappeler la platine 3 à la position soulevée lorsqu'elle n'est pas comprimée par le pied de l'utilisateur.They are subjected to the action of spring 9 which tends to separate them while the springs 10 and 11 tend to return the plate 3 to the raised position when it is not compressed by the foot of the user.

La plaquette mobile 8, avantageusement réalisée en matière plastique, apparaît mieux en fig. 4, 5 et 6 où l'on peut clairement apercevoir les plans inclinés 12 et 13 qui agissent sur les parties courbes des bras 1 et 2, au niveau des dépressions 14 et 15 visibles en fig. 3.The movable plate 8, advantageously made of plastic, appears better in FIG. 4, 5 and 6 where we can clearly see the inclined planes 12 and 13 which act on the curved parts of the arms 1 and 2, at the depressions 14 and 15 visible in fig. 3.

Les ailettes latérales 16 et 17 (fig. 4 et 5) qui font latéralement saillie sur les côtés de la plaquette mobile 8 font fonction d'organes d'arrêt afin d'empêcher à cette dernière de sortir de la platine 3.The lateral fins 16 and 17 (FIGS. 4 and 5) which protrude laterally from the sides of the movable plate 8 act as stop members in order to prevent the latter from coming out of the plate 3.

Les ailettes 16 et 17 peuvent évidemment être remplacées par un plan incliné ménagé sur la partie antérieure de la plaquette 8.The fins 16 and 17 can obviously be replaced by an inclined plane formed on the front part of the plate 8.

En fig. 7 et 8 la plaquette 8 est montrée retenue sur la platine 3 (fig. 3) par l'intermédiaire de l'encadrement métallique 18, respectivement en position soulevée (fig. 7) et en position abaissée (fig. 8).In fig. 7 and 8 the plate 8 is shown retained on the plate 3 (fig. 3) by means of the metal frame 18, respectively in the raised position (fig. 7) and in the lowered position (fig. 8).

Dans le premier cas les bras 1 et 2 se trouvent en position élargie sous l'action du ressort 9, tandis que dans le second ils se trouvent en position resserrée sous l'action des plans inclinés 12 et 13 de la plaquette mobile 8.In the first case, the arms 1 and 2 are in the enlarged position under the action of the spring 9, while in the second they are in the tightened position under the action of the inclined planes 12 and 13 of the movable plate 8.

Les avantages présentés par le frein de ski suivant l'invention sont évidents, l'abaissement de la platine mobile 8 sous l'action de la chaussure de l'utilisateur provoquant le soulèvement des bras mobiles de freinage 1 et 2 et en même temps leur déplacement vers l'intérieur du ski sous l'action des plans inclinés 12 et 13 de la plaquette mobile 8, ces plans inclinés travaillant à l'encontre du ressort de rappel 9.The advantages presented by the ski brake according to the invention are obvious, the lowering of the movable plate 8 under the action of the shoe of the user causing the lifting of the mobile braking arms 1 and 2 and at the same time their displacement towards the interior of the ski under the action of the inclined planes 12 and 13 of the mobile pad 8, these inclined planes working against the return spring 9.

En revanche lorsque pour une raison quelconque le ski doit se libérer de la chaussure de l'utilisateur, la platine mobile 3 se soulève sous l'action des ressorts 10 et 11 tandis que les bras de freinage 1 et 2 s'écartent et s'abaissent sous l'action du ressort 9.On the other hand when, for any reason, the ski must be released from the shoe of the user, the movable plate 3 is raised under the action of the springs 10 and 11 while the braking arms 1 and 2 move apart and are lower under the action of spring 9.

Bien évidemment les détails précis de construction du frein pour ski ont été décrits ici et représentés dans les planches de dessin annexées suvant une forme particulière de réalisation structurelle, indiquée à simple titre d'exemple non limitatif, ces détails pouvant affecter des formes et des aspects différents tout en restant conformes aux caractéristiques de l'invention, sans pour celà sortir de l'étendue du brevet.Obviously the precise details of construction of the ski brake have been described here and represented in the appended drawing boards following a particular structural embodiment, indicated by simple non-limiting example, these details being able to affect shapes and aspects. different while remaining consistent with the characteristics of the invention, without thereby departing from the scope of the patent.
