Problems solved by technology

[0004] However, despite the use of these adjustment systems, adjusting the position of the reset member is a very complex operation and requires the chronograph to be made with particular precision, as well as the necessary machining operations during the assembly of the mechanism

Embodiment Construction

[0014] Figure 1 to Figure 3 It is a simplified plan view of one side of the dial, showing a part of the movement 1 including the chronograph mechanism according to the present invention, respectively the first, second and third layout forms, corresponding to the stop, running and reset states of the chronograph respectively .

[0015] Obviously, the movement shown is not limited to the example shown, but a person skilled in the art can also adapt the movement shown to a chronograph mechanism arranged on one side of the bridge, so as to be able to implement the subject matter of the invention, But none of this departs from the scope of the present invention.

[0016] Said movement 1 comprises frame members, in particular a plate 2 on which are mounted moving members, levers, rockers and other chronograph components, this description only details those components that are relevant to the chronograph mechanism .

[0017] The chronograph mechanism includes a chronograph counte...

Abstract

The invention relates to a chronograph stopwatch mechanism comprising at least one minutes counter (20), and one hours counter (30) which are located both on the same side of the plate, first and second resetting members (23,33,42,43) each having a bearing surface and being able to pivot between a low position, in which each bearing surface cooperates with the periphery of a resetting cam (22,32) of one of the counters, and a high position, in which each bearing surface is located at a distance from the corresponding cam. The mechanism comprises retaining means (48, 50, 60) for keeping each of the resetting members in its high position, comprising a first retaining member (48, 50) acting directly on a first resetting member (42) and able to be released in response to an action by a user, and a second retaining member (60) acting directly on the second resetting member(43) and able to be released in response to a pivoting of the first resetting member (42) in the direction of its low position.

Description

technical field [0001] The invention relates to a chronograph stopwatch mechanism of a mechanical or automatic chronograph movement. The invention relates in particular to such a mechanism mountable on a chronograph movement plate, said plate having a bridge side and a dial side, the chronograph mechanism comprising a minute counter and an hour counter, both located on same side of the board. [0002] The chronograph mechanism also includes first and second reset members, each member having a bearing surface mounted for rotation about the plate between a low position and a high position, in which each bearing surface is in contact with the The periphery of a reset cam of a counter cooperates, and in the high position, each bearing surface is located at a certain distance from the corresponding cam. The chronograph mechanism also includes fixing means for holding each return member in its high position, and elastic means arranged to rotate the return members towards their res...
