Embodiment Construction

[0020] figure 1 The striking mechanism is shown mounted on a frame 1 which forms the frame of the striking unit or an additional module of the striking unit. This mechanism comprises a strike spring 10 with a drum surrounded by teeth 11 . A prime mover spring 12 is housed inside the drum. The teeth 11 are combined with a gear wheel 15 which is attached to a striking wheel 20 . The teeth 21 of this wheel alternately drive the anchor 30 , which is mounted to oscillate about a pivot axis 33 . The anchor 30 is attached to a striking hammer 40 and forms a striking part therewith. The anchor is used to cause the striking hammer to swing so that it is timed to strike the resonating member 50, in this case a striking bell.

[0021] To this end, the anchor has two lugs or pawls 31, 32 against which the teeth 21 of the striking wheel 20 alternately slide in abutment when the motive element 10 drives the striking wheel 20 in rotation, thereby causing the anchor 30 to oscillate, and ...

Abstract

This watch movement part comprises a frame (1) bearing a striking work mechanism which comprises: a motor member (10) kinematically linked with a striking work wheel (20), a striking work hammer (40), an anchor (30) with two pallets (31, 32) engaged alternately with said striking work wheel (20) and cooperating with said striking work hammer (40) to make it oscillate between a first position striking a resonant member (50) and a second position, and a limiting spring (60) defining said second position, and wherein the anchor (30) and the striking work hammer (40) form a single striking work member mounted to pivot on the frame (1).

Description

technical field [0001] The invention relates to watch movement components. Background technique [0002] The watch movement according to the present invention comprises a frame carrying a striking mechanism including a motive part which is kinematically connected with a striking wheel, a striking part mounted to pivot on the frame, and a striking hammer attached to the The anchor on the anchor has two pawls (pallet), the pawl alternately engages with the striking wheel, so that the striking hammer is in the first position of striking the resonance member (resonant member) and is limited by the limiting member swing between the formed second positions. [0003] The frequency of oscillation of the striking hammer must be low enough to allow the sound to be diffused when the gong of the striking mechanism comes into resonance, while at the same time maximizing the duration of the gong. [0004] A typical striking mechanism includes a mainspring combined with a gearwheel attac...
