Embodiment Construction

[0019] In the following description, elements of a timer reset system well known in the art are only briefly described.

[0020] Figure 1a and 1b Shown is a bottom view of the main elements of the chronograph reset system 1 for resetting the chronograph to a position prior to the reset operation. The timer reset system is usually also included in the following description Figure 4 and Figure 5 There is a more detailed description of the timer counting gear train 2. It is conceivable to install reset system 1 in a timepiece comprising a basic time movement and a chronograph movement, capable of running autonomously with its own movement and thus with its own barrel. However, it is also possible to use the basic movement of a timepiece with a chronograph.

[0021] The reset system 1 comprises a chronograph wheel set 3, which is usually a seconds wheel set, for Figure 4 and Figure 5 The timer in counts the gear train 2 part. The chronograph counting gear train compris...

Abstract

The invention relates to a system (1) for resetting a chronograph, which is provided with a chronograph counting geartrain (2), which includes a minute counter having a minute wheel set (4), and a seconds counter, which includes a chronograph wheel set (3). The system (1) includes a hammer (6) blocked by a blocking means (11) and displaceable from an inactive position, where the hammer (6) is blocked by the blocking means, to an active position, when the hammer (6) is unblocked, for resetting the chronograph in contact with the various wheel sets (3, 4); a flexible element (10), such as an embedded spring, connected between a reset control means (12) and the hammer (6) used for resetting the chronograph, the flexible element being configured to store energy during a displacement of the control means before unblocking the hammer (6) blocked by the blocking means (11), when the hammer (6) is unblocked, to restore the stored energy and drive the hammer (6) to reset the chronograph,.

Description

technical field [0001] The present invention relates to timer reset systems. The chronograph reset system is provided with a chronograph counting gear train comprising at least a minute counter with a minute wheel set and a seconds counter with a chronograph wheel set. The chronograph reset system includes a hammer blocked by a blocking mechanism, and the hammer is movable from an inactive position in which the hammer is blocked by the blocking mechanism to an active position in which the hammer is not blocked for use with a plurality of The timer for wheelset contact is reset. Background technique [0002] Typically, a chronograph mechanism includes a chronograph counting gear train that allows time to be counted from seconds by a chronograph wheel set or seconds counter, to minutes by a minutes counter, and optionally to hours by an hours counter. Each counter includes an indicator mechanism that moves on a corresponding scale. When the chronograph is reset, the indicat...
