Description
<Desc/Clms Page number 1>
Masse de remontage oscillante pour pièce d'horlogerie Certaines masses de remontage oscillantes pour pièces d'horlogerie comprennent une partie pesante supportée par une plaque elle-même montée rotati- vement sur le bâti de la pièce. On a déjà eu l'idée de pratiquer dans cette plaque un petit nombre de fentes de 2 à 4 radiales ou une grande ouverture circulaire ou semi-circulaire dans le but que cette masse puisse mieux absorber les chocs auxquels elle est soumise lors de sa rotation.
La présente invention a pour but d'augmenter ce résultat par un nombre plus grand de fentes faites selon une disposition spéciale de celles-ci.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention ainsi que deux variantes.
La fig. 1 est une vue en plan de la forme d'exécution, et la fig. 2, une coupe par II-II de la fig. 1.
Les fig. 3 et 4 représentent chacune, en plan, une variante.
La forme d'exécution représentée comprend une partie pesante 1 fixée à une :plaque mince 2, en forme de secteur, par le moyen de rivets 3 ; à son sommet, cette plaque est munie d'un axe 4 destiné à s'engager dans des paliers, non représentés, du bâti de la pièce d'horlogerie.
La plaque est ajourée de façon à présenter un grand nombre de fente 5 en arc de cercle, dont le centre se trouve sur l'axe de rotation 4a de la plaque. Elles sont disposées transversalement par rapport aux rayons 8 de cette plaque et .sont disposées sur quatre rangs en quinconce ; elles limitent entre elles des languettes élastiques 6 reliées par des ponts également élastiques 7 qui sont disposés suivant les rayons 8.
Supposons qu'un choc radial s'exerce sur le .pont 7 ; il sera transmis aux deux languettes 6a et 6b situées à droite et à gauche ; la languette 6a par exemple est reliée au pont 7a ; comme celui-ci est aussi élastique, il absorbera une .partie du choc et le transmettra à la languette 6c allant du pont 7a au pont 7b qui agira à son tour sur les languettes qui suivent ; de cette façon, à chaque choc, la presque totalité des languettes sera mise à contribution ; un phénomène analogue se passera lors d'un choc radial, et ceci quelle que soit la direction de ces chocs.
La variante de la fig. 3 présente ,des fentes rectilignes, et celle de la fig. 4 comprend, à côté d'une plage principale, 9, deux plages. latérales 10 également ajourées d'après le même principe.

Oscillating winding mass for timepieces Certain oscillating winding masses for timepieces include a heavy part supported by a plate which is itself rotatably mounted on the frame of the part. We have already had the idea of practicing in this plate a small number of slots of 2 to 4 radials or a large circular or semi-circular opening in order that this mass can better absorb the shocks to which it is subjected during its rotation. .
The object of the present invention is to increase this result by a greater number of slits made according to a special arrangement thereof.
The accompanying drawing represents, by way of example, one embodiment of the object of the present invention as well as two variants.
Fig. 1 is a plan view of the embodiment, and FIG. 2, a section through II-II of FIG. 1.
Figs. 3 and 4 each show, in plan, a variant.
The embodiment shown comprises a heavy part 1 fixed to a: thin plate 2, in the form of a sector, by means of rivets 3; at its top, this plate is provided with a pin 4 intended to engage in bearings, not shown, of the frame of the timepiece.
The plate is perforated so as to have a large number of slits 5 in an arc of a circle, the center of which is on the axis of rotation 4a of the plate. They are arranged transversely to the spokes 8 of this plate and are arranged in four staggered rows; they limit between them elastic tongues 6 connected by also elastic bridges 7 which are arranged along the spokes 8.
Let us suppose that a radial shock is exerted on the .bridge 7; it will be transmitted to the two tabs 6a and 6b located on the right and on the left; the tongue 6a for example is connected to the bridge 7a; as it is also elastic, it will absorb some of the shock and transmit it to the tongue 6c going from the bridge 7a to the bridge 7b which will in turn act on the following tongues; in this way, at each impact, almost all of the tabs will be used; a similar phenomenon will occur during a radial impact, regardless of the direction of these impacts.
The variant of FIG. 3 shows rectilinear slots, and that of FIG. 4 includes, next to a main beach, 9, two beaches. side 10 also perforated according to the same principle.
