Description
Pare-choc pour paliers de pièces d'horlogerie. Il est des paliers pare-choc pour pièces d'horlogerie dans lesquels la pierre percée ,est suspendue à un ressort ou dispositif élas tique en forme de spirale ou d'une autre forme, pincé dans un corps de palier. Ceci se fait :généralement au moyen d'une bague fendue qui maintient ce ressort en place sans en gêner les mouvements.
Dans le dispositif pare-,choc selon l'invention, la pierre contre- pivot, qui fait toujours partie de ces genres de palier, est maintenue par un ressort dans une feuillure de la bague fendue. Ceci permet de gagner quelques dixièmes de milli mètres dans la hauteur du ,dispositif.
Le -dessin annexé montre, à titre,d'exem- ple, une forme d'exécution du dispositif pare choc selon l'invention.
La fig. 1 en est une vue en plan avec parties en coupe, et la fig. 2 en est une coupe, par le plan II-II de la fig. 1, passant par l'axe du mobile à protéger.
Le coq est désigné par 1, le coqueret par 2. Dans la planche -de coq est ajusté à frottement dur un corps de palier 3 qui a la forme d'un contenant cylindrique dont le fond est percé d'un trou pour laisser passer l'axe 5 -du mobile à protéger. Le pignon 6 de cet axe tourne dans une pierre percée 7 chassée dans la partie centrale d'un dispositif élastique 8 qui est maintenu dans le corps de palier par une bague 9 fendue et faisant ressort. Cette bague possède une feuillure 10 dans laquelle le contre-pivot_ 11 est maintenu par un ressort étoilé 12.
Le fonctionnement d'un pareil dispositif est connu: les composantes radiales des chocs sur la montre sont absorbés par le dispositif élastique 8, tandis que les composantes axiales tendent à ,soulever le contre-pivot à l'encontre de l'action du ressort étoilé 12.
Bumper for bearings of timepieces. There are bumper bearings for timepieces in which the pierced stone is suspended from a spring or elastic device in the form of a spiral or of another shape, clamped in a bearing body. This is done: generally by means of a split ring which keeps this spring in place without hindering its movements.
In the bumper device according to the invention, the counter-pivot stone, which still forms part of these types of bearing, is held by a spring in a rebate of the split ring. This makes it possible to save a few tenths of a millimeter in the height of the device.
The attached drawing shows, by way of example, one embodiment of the bumper device according to the invention.
Fig. 1 is a plan view thereof with parts in section, and FIG. 2 is a section through the plane II-II of FIG. 1, passing through the axis of the mobile to be protected.
The cock is designated by 1, the cockerel by 2. In the cock board is fitted with hard friction a bearing body 3 which has the shape of a cylindrical container, the bottom of which is pierced with a hole to allow the passage of l. axis 5 - of the mobile to protect. The pinion 6 of this axis rotates in a drilled stone 7 driven into the central part of an elastic device 8 which is held in the bearing body by a split ring 9 and springing. This ring has a rebate 10 in which the contre-pivot_ 11 is held by a star spring 12.
The operation of such a device is known: the radial components of the shocks on the watch are absorbed by the elastic device 8, while the axial components tend to raise the counter-pivot against the action of the star spring. 12.
