摘要 | The invention relates to a clock movement including a frame (6) having a barrel (1) that contains a mainspring, a finishing gear train (2-4), an escapement mechanism (5, 7), and a spiral balance spring (8). The frame (6) comprises first clamp bodies (25, 24) for receiving respective pivotal movement members of the escapement wheel (5) and of the anchor (7), and second homologous clamp bodies (22, 26) alternating with the first clamp bodies (25, 24), the first and second clamp bodies (25, 22) of the escapement wheel being located on a circle centered on the axis of the mean wheel (3) of the finishing gear train and defining a plane that is orthogonal to said axis. | ||||||

说明书全文 | The present invention relates to a clockwork movement comprising a frame supporting a barrel containing a mainspring, a finishing gear train, an escapement mechanism and a spiral-balance. A clockwork movement is capable of receiving various “complications”, a name given by clockmakers to all the additional mechanisms designed to indicate time intervals other than the hours, the minutes and the seconds. These mechanisms often consist of additional modules that are fitted to the clockwork movement and are connected to it by one of its mobiles of the finishing gear train or of the motion-work gear train. In some cases, the presence of a seconds hand and therefore of a seconds wheel at the center may form an obstacle to the additional mechanism with which it is desired to furnish the clockwork movement. In other cases, the seconds wheel at the center of the clockwork movement is not an obstacle and is desired. The drawback arises from the fact that it is necessary to have two different clockwork movements to respond to these requirements. Two different clockwork movements involve two distinct production lines. The object of the present invention is to make it possible, from one and the same clockwork movement, to have a seconds wheel at the center and a seconds wheel off-centered. Accordingly, the subject of the present invention is a clockwork movement as claimed in claim 1. The advantage of such a movement is that it allows a more advanced rationalization of production on the basis of one and the same movement, while nowadays it is necessary to change movement depending on the type of complication with which it is desired to fit the timepiece. It is obvious that making it possible to fit one and the same movement with the largest possible number of complications substantially simplifies production planning. The appended drawings illustrate schematically and as an example, one form of execution of the clockwork movement that is the subject of the present invention. Since the minutes wheel 2 is not situated at the center of the clockwork movement, the third wheel 3 supports a second pinion (not shown) on the side of the movement turned toward the face and meshes with a minutes wheel which is situated at the center of the movement and which supports the cannon-pinion (not shown). These elements are known to those skilled in the art and are not necessary to the understanding of the present invention. The finishing gear train that has just been described is supported, as usually between bearings secured to a plate 6 and bearings secured to bridges fixed to the plate 6. These bridges have been removed to make it possible to see the finishing gear train. As illustrated in particular by As can be ascertained in With reference now to Moreover The pallets bridge 13 is moved angularly about the pivoting spindle of the spiral-balance 8 and the auxiliary frame 9 comprises means for the positioning and the fixing of the pallets bridge 13 by the screws 14 in the two positions, that of As can be seen, Moreover, the auxiliary frame 9 makes it possible to carry out the installation of this auxiliary frame 9 according to the version for seconds wheel at the center or according to the version for seconds wheel off-centered. It is then sufficient to install the version of this module preassembled with the escapement wheel 5 pivoted in the bearings or bearing seats 12, 25 and the pallets 7 in the bearings or bearing seats 15, 24 on a plate 6 with seconds wheel at the center or to install the version of this module preassembled with the escapement wheel 5 pivoted in the bearings or bearing seats 20, 22 and the pallets 7 in the bearings or bearing seats 15, 26 on a plate 6 with seconds wheel 4 off-centered. The total identity of all the components of the two versions of the clockwork movement is also an advantage for after-sales service, because all the parts can be used without distinction in both versions, which simplifies their replacement by removing the risk of errors. |
