Timepiece intended to indicate the power reserve

摘要

A horological instrument intended to indicate the power reserve, includes a barrel (1) provided with a drum (2) arranged to turn in one direction during operation of the horological instrument, the drum (2) including around the periphery thereof at least one power reserve scale (4). At least one hand (13) is arranged to turn with the drum (2) and cooperates with a corresponding power reserve scale (4). Furthermore, a mechanism for displacing the hand or hands (13) is arranged to displace the hand or hands by one step with respect to the corresponding scale of the drum (2) with each revolution or with each fraction of revolution of the drum (2) and the hand (13) in order to progressively indicate the power reserve.

1. A horological instrument for indicating power reserve, including:
a barrel (1) provided with a drum (2) arranged to turn in one direction during operation of the horological instrument, the drum (2) including on its periphery at least one power reserve scale (4) which extends around the periphery of the drum (2), at least one hand (13) arranged to turn with the drum (2) and which cooperates with a corresponding power reserve scale (4) located on the periphery of the drum (2), and a mechanism for displacing the hand or hands (13) arranged to displace the hand or hands by one step with respect to the corresponding scale of the drum (2) with each revolution or with each fraction of revolution of the drum (2) and the hand (13) in order to progressively indicate the power reserve on the periphery of the drum (2), wherein the barrel (1) drives a part (6) including one finger or several fingers (14, 15) distributed around the periphery thereof, this finger or these fingers (14, 15) drive with each revolution or each fraction of revolution a satellite wheel (7) carried by the cover (3) of the drum (2), said satellite wheel (7) being connected to a rotatable member carrying said at least one hand (13) in order to displace this rotatable member by one step for each revolution or each fraction of revolution, and wherein the part (6) includes two diametrically opposite fingers.
