Abstract
Chiming timepiece comprising a movement and an acoustic indication mechanism with a control mechanism controlling the performance of a chime or tune by setting control lifts in motion that each actuate a hammer arranged to strike a gong, and each control lift is releasable between a released position, in which it is decoupled from the control mechanism, and a resting position, in which it is able to be driven for actuation of the hammer by the control mechanism that is set in motion by the movement, or by a manual actuator, and tune selection devices for the selection of at least one particular chime or tune are controlled by this movement or by a manual selector and control the passage of each control lift from its released position to its resting position or vice versa.
Claims26
A chiming timepiece comprising a timepiece movement and a manual control operable by a user and comprising at least one acoustic indication mechanism with a control mechanism arranged to control the performance of at least one chime or tune by setting in motion at least one control lift to actuate at least one hammer arranged to strike a gong, where at least one said control lift is movable between at least one released position, in which it is decoupled from said control mechanism, and a resting position, in which it is able to be driven for the actuation of said hammer by said control mechanism that is set in motion, or also by said timepiece movement, or also by an actuator forming part of said manual control, and where said timepiece also comprises tune selection devices for the selection of at least one particular chime or tune, which are controlled either by said timepiece movement or by a selector forming part of said manual control, and where said tune selection devices are arranged to control the passage of said at least one control lift from its released position to its resting position or vice versa, where said acoustic indication mechanism comprises a plurality of control levels parallel to one another and parallel to lift planes, in which said control lifts are arranged, and in each of these control levels said control mechanism comprises a control part, which, when said control part is set in motion by said timepiece movement or said actuator, is arranged to drive at least one said control lift positioned in its said resting position and located in a lift plane coplanar with said control level of said control part, wherein said tune selection devices are arranged to simultaneously control in a given lift plane the passage of each control lift controlled by said control part located at a said control level controlling said given lift plane from one to the other of its said released or resting positions.
