Abstract

The oscillating weight (9-10) which serves to drive the rotor of a current generator intended to charge a supply capacitor of the movement of the electronic watch is located above the dial (11) of the latter, which dial serves as its support board. The arm (10) of this weight is articulated to the centre of the movement on a ball bearing carried by the board/dial (11). The hour-circle (16) has a relatively small diameter, leaving free the annular part of the dial (11) opposite which the peripheral part (9) of the weight (9-10) moves. The dial (11) simultaneously acts as a support element for the outer ring of the ball bearing supporting the rotating oscillating weight (9-10) and is fixed to the housing of the movement by screws (12). The outer ring of the support bearing of the weight (9-10) is integral with a pinion engaged with a pinion (21) belonging to the train driving the rotor of the electric generator which the said weight drives. <IMAGE>

Description

La présente invention a pour objet une montre comprenant une masse rotative oscillante pro­ductrice de l'énergie nécessaire à la marche du mou­vement, pivotée au centre de celui-ci.The subject of the present invention is a watch comprising an oscillating rotary mass producing the energy necessary for the movement to run, pivoted in the center of the movement.

De telles montres sont connues. Leur masse rotative oscillante sert, le plus généralement, au remontage du ressort-moteur et, dans le cas de mon­tres électroniques, peut servir à l'entraînement du rotor d'un générateur de courant apte à charger un accumulateur ou un condensateur fournissant l'énergie motrice assurant la marche du mouvement.Such watches are known. Their oscillating rotary mass is used, most generally, for winding the mainspring and, in the case of electronic watches, can be used to drive the rotor of a current generator capable of charging an accumulator or a capacitor supplying the motor energy ensuring the movement's movement.

Dans les montres à masse rotative oscil­lante connues, la masse rotative se trouve placée, le plus généralement, à la périphérie du mouvement, le bras qui relie cette partie périphérique au centre de rotation passant sous le mouvement, du côté ponts de celui-ci, entre le fond de la boîte et le mouvement.In watches with known oscillating rotating mass, the rotating mass is most generally placed at the periphery of the movement, the arm which connects this peripheral part to the center of rotation passing under the movement, on the bridge side thereof, between the bottom of the case and the movement.

Le but de la présente invention est de four­nir une construction nouvelle d'une telle montre, plus particulièrement du montage de la masse rotative oscil­lante de celle-ci, qui soit à la fois peu encombrante et robuste, et qui, de surcroît, permette une liaison aisée entre la masse et le rouage conduisant à l'organe qu'elle doit entraîner.The object of the present invention is to provide a new construction of such a watch, more particularly the mounting of the oscillating rotary mass thereof, which is both compact and robust, and which, moreover, allows a easy connection between the mass and the gear train leading to the organ that it must drive.

Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.

  • La fig. 1 est une vue en plan d'une montre-­bracelet.
  • La fig. 2 est une coupe du mouvement de cette montre, passant par le centre de celle-ci, à plus grande échelle.
  • La fig. 3 est une coupe de la partie périphé­rique du mouvement de la montre de la fig. 1, également à plus grande échelle, et
  • La fig. 4 est une vue en plan d'un dé­tail de cette montre, également à plus grande échelle.
The drawing represents, by way of example, an embodiment of the subject of the invention.
  • Fig. 1 is a plan view of a wristwatch.
  • Fig. 2 is a section of the movement of this watch, passing through the center thereof, on a larger scale.
  • Fig. 3 is a section through the peripheral part of the movement of the watch in FIG. 1, also on a larger scale, and
  • Fig. 4 is a plan view of a detail of this watch, also on a larger scale.

La montre-bracelet représentée, désignée d'une façon générale par 1, comprend un mouvement 2 logé dans une boîte étanche comprenant un fond-carrure 3 et une glace 4 engagée dans la partie périphérique 3a du fond-carrure, constituant le corps de boîte proprement dit.The wristwatch shown, generally designated by 1, comprises a movement 2 housed in a sealed box comprising a case back 3 and a crystal 4 engaged in the peripheral part 3 a of the case back, constituting the body of box itself.

Cette montre étant électronique, elle est dépourvue d'organe de remontage mais comporte en re­vanche un organe de mise à l'heure constitué par un anneau 5, visible à la fig. 3, articulé sur une pièce 6 qu'il sert à entraîner en rotation, et qui peut soit occuper la position représentée, dans laquelle il est rabattu dans une creusure 7 du fond-carrure 3, soit occuper une position relevée permettant son ac­tionnement.This watch being electronic, it does not have a winding member but, on the other hand, includes a time-setting member constituted by a ring 5, visible in FIG. 3, articulated on a part 6 which it serves to drive in rotation, and which can either occupy the position shown, in which it is folded into a recess 7 in the backband 3, or occupy a raised position allowing its actuation.

Cette montre comporte un générateur de courant destiné à charger un condensateur électrique alimentant le mouvement. Le rotor de ce générateur, désigné par 8 (fig. 2) est actionné par une masse rotative oscillante pivotée au centre du mouvement, représentée en détail à la fig. 4, qui comprend une partie périphérique massive 9, en forme de segment de couronne, et un bras 10 reliant cette partie pé­riphérique 9 au centre de pivotement de ladite masse. La partie périphérique 9 est située, comme le montre la fig. 3, entre la périphérie du mouvement 2 et la carrure 3a. Quant au bras 10, en arc de cercle, il est disposé de façon à apparaître comme étant situé dans le prolongement de la partie périphérique 9. Ce bras 10 est situé au-dessus du cadran de la mon­tre, désigné par 11.This watch includes a current generator intended to charge an electric capacitor supplying the movement. The rotor of this generator, designated by 8 (fig. 2) is actuated by an oscillating rotary mass pivoted in the center of the movement, shown in detail in fig. 4, which comprises a massive peripheral part 9, in the form of a ring segment, and an arm 10 connecting this peripheral part 9 to the pivot center of said mass. The peripheral part 9 is located, as shown in fig. 3, between the periphery of the movement 2 and the middle part 3 a . As for the arm 10, in an arc, it is arranged so as to appear as being in the extension of the peripheral part 9. This arm 10 is located above the watch face, designated by 11.

Ce cadran 11 est relativement épais et sert de planche de soutien de la masse; il est fixé au bâti du mouvement 2 à l'aide de trois vis 12 vi­sibles à la fig. 1. Cette planche 11 présente une partie centrale 11a en retrait par rapport à son plan général (fig. 2), munie elle-même, en son cen­tre, d'un collet 11b sur lequel est chassée la bague intérieure, désignée par 13, d'un roulement à billes dont la bague extérieure, désignée par 14, porte, chassé sur elle, le bras de liaison 10 de la masse rotative oscillante. Il est à remarquer que cette bague extérieure 14 du roulement à billes est taillée en 14a de façon à constituer un pignon, ainsi solidai­re de la masse, qui forme le premier élément d'un rouage conduisant au rotor 8 du générateur de courant.This dial 11 is relatively thick and serves as a mass support board; it is fixed to the frame of the movement 2 using three screws 12 visible in FIG. 1. This board 11 has a central part 11 a set back from its general plane (fig. 2), itself provided, in its center, with a collar 11 b on which the inner ring is driven, designated by 13, a ball bearing whose outer ring, designated by 14, carries, driven on it, the link arm 10 of the oscillating rotary mass. It should be noted that the outer ring 14 of ball bearing 14 is cut in a manner that constitutes a pinion and integral with the mass which forms the first element of a gear train driving the rotor 8 of the current generator.

Le collet central 11b de la planche 11 formant cadran-support de masse est traversé par les canons supportant les aiguilles de la montre, désignés d'une façon générale par 15 (fig. 2). Le tour d'heures, désigné par 16 à la fig. 1, n'est pas situé à la périphérie du cadran, mais au centre de celui-ci, les aiguilles de quantièmes d'heures et de minutes, désignées par 17, 18 et 19, respectivement, étant dimensionnées, en longueur, de façon à corres­pondre à ce cadran central. Ainsi la partie périphé­rique du cadran, balayée par la partie 9 de la masse, est libre de toute indication.The central collar 11b of the plate 11 forming the dial-mass support is crossed by the barrels supporting the hands of the watch, generally designated by 15 (FIG. 2). The hour circle, designated by 16 in fig. 1, is not located at the periphery of the dial, but at the center of the latter, the date hands of hours and minutes, designated by 17, 18 and 19, respectively, being dimensioned, in length, so as to correspond to this central dial. Thus the peripheral part of the dial, swept by the part 9 of the mass, is free from any indication.

La planche 11 de soutien de la masse os­cillante rotative est percée d'un trou 20 (fig. 2) dans lequel est logé un pignon 21 en prise avec un pignon 22 monté sur l'arbre, désigné par 23, du rotor 8 du générateur. Ce pignon 21 est lui-même en prise avec la denture 14a de la bague extérieure 14 du rou­lement de masse. Comme le montre la fig. 2, l'engrè­nement du pignon 21 et de la denture 14a s'effectue sur une partie de leur hauteur seulement, le roule­ment étant logé dans une creusure 24 que ménage, sur la face extérieure de la planche 11, sa partie cen­trale 11a en retrait; le pignon 21 est logé sensible­ment dans l'épaisseur de cette planche 11.The support plate 11 for the rotary oscillating mass is pierced with a hole 20 (fig. 2) in which is housed a pinion 21 engaged with a pinion 22 mounted on the shaft, designated by 23, of the rotor 8 of the generator . This pinion 21 is itself in engagement with the toothing 14a of the outer ring 14 of the ground roll. As shown in fig. 2, the meshing of the pinion 21 and the teeth 14 a is carried out over part of their height only, the bearing being accommodated in a recess 24 that cleaning on the outer face of the board 11, its central portion 11a set back; the pinion 21 is housed substantially in the thickness of this board 11.

Il est à remarquer que le pignon 21 est visible, comme le montre la fig. 1, de même que le roulement central supportant la masse rotative os­cillante.It should be noted that the pinion 21 is visible, as shown in FIG. 1, as well as the central bearing supporting the oscillating rotary mass.

Les différents éléments du rouage du mouvement de la montre, dont certains sont visibles à la fig. 2, ne seront pas décrits ici, étant connus en soi.The different parts of the clockwork, some of which are visible in fig. 2, will not be described here, being known per se.
