Wheel for clock work in clock element, has dorsal notch whose internal end is located close to pivot axis, where internal end extends under pin foot or under internal prolongation of ventral notch along pivot axis

摘要

The wheel (10) has backlash teeth (2), where each tooth comprises a pin (3) that covers a pin foot (31). An elastic blade (4) projects from a blade foot (41). The blade foot is separated from the pin by a ventral notch (5) comprising an under-surface (43) on a side that is opposed to the pin. The pin delimits a dorsal notch (6). An internal end (61) of the dorsal notch is located close to a pivot axis (D). The internal end extends under the pin foot or under an internal prolongation (52) of the ventral notch along the pivot axis. An independent claim is also included for a clock element.
