Problems solved by technology

Such a device is disadvantageous because the curved flexible strip and the return spring are difficult to manufacture and shape
Moreover, such a device takes up too much space in the direction of the axis of the carriage, which makes it difficult to incorporate said device into a movement of small thickness
Finally, such devices are not suitable for balance wheels with interrupted, scalloped or split rims

Embodiment Construction

[0023] refer to Figures 1 to 3 , a timepiece movement according to a particular embodiment of the invention comprising a drive unit in the form of a barrel 1 , a gear train 2 and a tourbillon mechanism (tourbillon) 3 . In the framework of the present invention, by "tourbillon" is meant any rotary adjustment system, such as an actual tourbillon or a carousel. Tourbillon mechanism 3 comprises a carriage 4 mounted around an axis 5 and composed of a lower carriage part 6 and an upper carriage part 7 connected to each other by struts 8 . Struts 8 (whose number is three in the example shown) each pass through screws 11 (see image 3 ) connected to each other constitutes a portion 9 defined by the lower bracket portion 6 and a portion 10 defined by the upper bracket portion 7 . Axel 5 of carriage 4 carries a seconds hand (not shown). In carriage 4 , balance 12 , balance spring 13 and escapement 14 are mounted parallel to the plane of carriage 4 in a conventional manner. Strut 8 ...

Abstract

The invention relates to a clockwork with a tourbillon mechanism and a balance stop mechanism. The tourbillon mechanism includes a cage (4) and a rocker (12) mounted in the cage (4). The cage (4) comprises a lower cage portion (6) and an upper cage portion (7) connected by pillars (8). The stop mechanism includes a stop member (18) which is in rigid fixing without rotating with respect to the cage (4) and is capable of coming into contact with the balance (12) for the stop and a device (27, 28, 38-40 ) for actuating the stop element (18). The stop member (18) is in the form of a disk coaxial to the cage (4) through which the pillars (8) and having an outer periphery located radially beyond the pillars (8). The actuating device (27, 28, 38-40) comprises at least one actuating element adapted to cooperate with the outer periphery (20a) for moving the disc along the axis of the cage (4) so as to cause the stopping of the rocker (12) by friction between the disc and the rocker (12).

Description

technical field [0001] The invention relates to a timepiece movement with a tourbillon and a balance stop. Background technique [0002] A Tourbillon is a well known device used to compensate for rate changes caused by gravity by having the adjustment unit occupy all vertical positions. Tourbillon mechanisms include in particular a rotating carriage in which a spring-loaded balance and an escapement are mounted. Basically, the rotating carriage is driven by the movement's running wheel train, and the escapement gear meshes with a fixed fourth wheel. [0003] The balance stop mechanism, also called "balance wheel stop" or "seconds stop", has the function of stopping the balance wheel during time setting in order to restart the movement at a selected moment in order to, for example, set the seconds hand Synchronized with reference to seconds. As described for example in patent EP1840677, these mechanisms generally consist of elastic arms actuatable by a time setting lever a...
