Description
Masse pour montre à remontage automatique L'objet de la présente invention est une masse pour montre à remontage automatique.
Cette masse est caractérisée en ce qu'elle comprend un premier élément pendulaire sus ceptible de pivoter par rapport au bâti de la montre et dont les mouvements sont destinés à être transmis à l'arbre de barillet, et au moins un autre élément pendulaire pivotant librement dans le premier desdits éléments, en vue de lui transmettre une impulsion initiale destinée à faciliter son démarrage lors d'un changement de position de son axe de pivotement.
Une forme d'exécution de la masse, objet de l'invention, est représentée, à titre d'exem ple, au dessin annexé.
La fig. 1 en est une vue en plan, et la fig. 2 est une coupe selon la ligne <I>11-11</I> de la fig. 1.
La masse représentée est destinée à assurer le remontage d'une montre-bracelet. Elle com prend un premier élément 1 semi-circulaire, d'épaisseur uniforme, comprenant une pièce 2 chassée sur un axe 3 et présentant un évide ment cylindrique 4. L'axe 3 est perpendiculaire au plan de l'élément 1 et il est logé au centre du demi-cercle défini par cet élément (fig. 1).
L'axe 3 porte un pignon 5, en prise avec un dispositif de transmission relié à l'arbre de barillet de la montre, en vue d'effectuer le re- montage du ressort moteur sous l'action des déplacements de l'élément 1.
Un second élément 6, de forme semblable à celle de l'élément 1, à part l'évidement 4, est chassé sur un axe 7, par l'intermédiaire duquel il pivote dans l'élément 1, les paliers de l'axe 7 étant supportés, l'un par la pièce 2, et l'autre par une plaque 8 solidaire de la pièce 2 et re couvrant l'évidement 4.
La position de la plaque 8 par rapport à la pièce 2 est repérée par l'intermédiaire de deux goupilles 9 et elle est fixée sur cette pièce par deux vis 10.
La masse décrite constitue ainsi un pendule double et elle peut être pivotée dans le mou vement de la montre, par exemple entre la pla tine et un pont.
Elle a sur les masses constituées par un pendule simple l'avantage de démarrer plus facilement. La pratique a montré, en effet, que les organes de transmission du mouvement de la masse de remontage à l'arbre de barillet opposent souvent une résistance telle, qu'une masse habituelle immobile n'entre pas en mou vement lorsque la montre subit un déplacement lent.
Dans la construction décrite, en revanche, l'élément 6 se déplace très librement; il entre en mouvement lors du moindre déplacement de la montre et transmet de ce fait une impulsion initiale à l'élément 1, qui démarre en opérant le remontage de la montre.
Il est bien clair qu'on pourrait monter plu sieurs éléments 6 sur un même élément 1, ces éléments 6 étant tous pivotés librement autour d'axes parallèles. En particulier, dans le cas où l'élément 1 a la forme d'une masse de remon tage courante, comprenant une demi-couronne pesante reliée à un moyeu par des bras ou un voile mince, plusieurs évidements cylindriques pourraient être aménagés dans ladite couronne et de petits éléments pendulaires pivotés à l'in térieur de ces évidements.
Weight for a self-winding watch The object of the present invention is a weight for a self-winding watch.
This mass is characterized in that it comprises a first pendular element capable of pivoting relative to the frame of the watch and whose movements are intended to be transmitted to the barrel shaft, and at least one other pendular element pivoting freely in the first of said elements, with a view to transmitting to it an initial impulse intended to facilitate its starting during a change of position of its pivot axis.
One embodiment of the mass, object of the invention, is shown, by way of example, in the accompanying drawing.
Fig. 1 is a plan view thereof, and FIG. 2 is a section taken along the line <I> 11-11 </I> of FIG. 1.
The mass shown is intended for winding a wristwatch. It comprises a first semi-circular element 1, of uniform thickness, comprising a part 2 driven on an axis 3 and having a cylindrical recess 4. The axis 3 is perpendicular to the plane of the element 1 and it is housed in the center of the semi-circle defined by this element (fig. 1).
The axis 3 carries a pinion 5, in engagement with a transmission device connected to the barrel shaft of the watch, in order to carry out the reassembly of the mainspring under the action of the movements of the element 1 .
A second element 6, similar in shape to that of element 1, apart from the recess 4, is driven on a pin 7, through which it pivots in element 1, the bearings of pin 7 being supported, one by part 2, and the other by a plate 8 integral with part 2 and covering the recess 4.
The position of the plate 8 relative to the part 2 is marked by means of two pins 9 and it is fixed to this part by two screws 10.
The mass described thus constitutes a double pendulum and it can be pivoted in the movement of the watch, for example between the plate and a bridge.
Over masses formed by a simple pendulum, it has the advantage of starting more easily. Practice has shown, in fact, that the members for transmitting the movement of the winding mass to the barrel shaft often oppose a resistance such that a usual immobile mass does not move when the watch is subjected to a slow moving.
In the construction described, on the other hand, the element 6 moves very freely; it starts to move when the watch is moved the least and therefore transmits an initial impulse to element 1, which starts by winding the watch.
It is quite clear that several elements 6 could be mounted on the same element 1, these elements 6 all being freely pivoted about parallel axes. In particular, in the case where the element 1 has the form of a current winding mass, comprising a heavy half-crown connected to a hub by arms or a thin veil, several cylindrical recesses could be arranged in said crown. and small pendulum elements pivoted inside these recesses.
