Mechanism for moving an indicator of a clock
Abstract:
A mechanism for setting a clock hand indicates for example a date in defined positions of a scale. The mechanism includes a cam disc and a first rake which is connected to the cam disc in a force-transmitting manner and has teeth which engage into the teeth of a pinion and transmit a force. A second rake has teeth that engage into the teeth of the pinion. The second rake exerts a force on the teeth of the pinion that is opposite to the force exerted by the first rake exerts on the pinion. The first rake and the second rake are arranged so as to overlap, and the second rake can be borne pivotally around the first axle. The embodiment has the advantage that it is space-saving and the rakes stabilize one another mutually.
