Description
Pièce d'horlogerie à remontage automatique par masse oscillante. La présente invention a pour objet une pièce d'horlogerie à remontage automatique par masse oscillante. Cette pièce est caracté risée en ce que cette masse oscille autour du centre du mouvement et tourne autour d'un axe pivotant dans le bâti de ce mouvement et dans le fond de la pièce.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention, constituée par une montre- bracelet de forme ronde.
La fig. 1 en est une vue en plan et la fig. 2 une coupe axiale par II-II de la fig. 1; la fig. 3 est une coupe schématique à plus grande échelle du mécanisme de re montage.
La forme d'exécution représentée com prend une boîte 1 avec un fond 2 et un mou vement 3.
Le bâti du mouvement 3 porte en son centre une pierre 4 dans laquelle pivote l'axe 6 de la masse oscillante 5; l'autre extrémité de l'axe 6 pivote dans une pierre 7 fixée au centre du fond 2. La masse oscillante 5 affecte la forme d'un disque d'un diamètre sensiblement égal à celui du mouvement et échancré; elle est folle sur l'axe 6. Sur cet axe 6 sont figées deux roues dentées, l'une 8 au-dessous, l'autre 9 au-dessus de la masse oscillante. La roue 8 engrène avec une roue 10 qui transmet le mouvement par friction à une roue 11 qui coopère avec une roue 12 dont le pignon<B>13</B> entraîne une roue 14 dont le pignon 15 agit sur le rochet 16 du ba- rillet-moteur.
Avec la roue dentée 9 coopère un cliquet 17 porté par la masse et sollicité par un ressort 18 figé en 19 à la masse, le tout de manière que, le cliquet 17 engrenant avec la roue 9, la masse oscillante soit solidaire de son axe 6 lorsqu'elle se meut dans le sens correspondant au remontage du ressort; dans l'autre sens, le cliquet 17 glisse sur la roue 9 et libère la masse 5.
La forme de disque échancré donnée à la masse oscillante permet de réaliser une masse assez lourde dont le centre de gravité est re porté hors du centre de rotation. La disposition susdécrite présente<B>plu-</B> sieurs avantages: tout d'abord, la position de la masse en dehors du mouvement permet de donner à celle-ci un volume assez grand sans augmenter sensiblement le diamètre de la montre; ensuite, le pivotage de lamasse dans le bâti du mouvement et dans le fond écono mise un pont supplémentaire, simplifie la construction et diminue l'épaisseur de la montre.
Self-winding timepiece by oscillating weight. The present invention relates to a timepiece with automatic winding by means of an oscillating mass. This part is characterized in that this mass oscillates around the center of the movement and rotates around a pivoting axis in the frame of this movement and in the back of the part.
The appended drawing represents, by way of example, an embodiment of the object of the invention, constituted by a wristwatch of round shape.
Fig. 1 is a plan view thereof and FIG. 2 an axial section through II-II of FIG. 1; fig. 3 is a schematic section on a larger scale of the re-assembly mechanism.
The embodiment shown com takes a box 1 with a bottom 2 and a movement 3.
The frame of the movement 3 carries in its center a stone 4 in which the axis 6 of the oscillating weight 5 pivots; the other end of the axis 6 pivots in a stone 7 fixed to the center of the base 2. The oscillating mass 5 takes the form of a disc with a diameter substantially equal to that of the movement and notched; it is crazy on axis 6. On this axis 6 are fixed two toothed wheels, one 8 below, the other 9 above the oscillating mass. The wheel 8 meshes with a wheel 10 which transmits the movement by friction to a wheel 11 which cooperates with a wheel 12 whose pinion <B> 13 </B> drives a wheel 14 whose pinion 15 acts on the ratchet 16 of the ba - motor rillet.
With the toothed wheel 9 cooperates a pawl 17 carried by the mass and biased by a spring 18 fixed at 19 to the mass, all so that, the pawl 17 meshing with the wheel 9, the oscillating mass is integral with its axis 6 when it moves in the direction corresponding to the winding of the spring; in the other direction, the pawl 17 slides on the wheel 9 and releases the mass 5.
The scalloped disc shape given to the oscillating mass makes it possible to produce a fairly heavy mass, the center of gravity of which is brought out of the center of rotation. The above-described arrangement has <B> several </B> advantages: first of all, the position of the mass outside the movement makes it possible to give it a fairly large volume without appreciably increasing the diameter of the watch; then, the pivoting of the mass in the frame of the movement and in the economy caseback provides an additional bridge, simplifies construction and reduces the thickness of the watch.
