Embodiment Construction

[0028] The invention proposes to limit the rebound of the hammer. Here, it refers to the main rebound, ie the rebound from the large recoil of the hammer after impact, rather than the micro rebound which is also related to the vibration of the gong.

[0029] The invention relates to a timepiece striking mechanism 100 comprising a fixed part 105 and a control mechanism arranged to directly or indirectly control the movement of at least one hammer 1 . The control mechanism more particularly but not exclusively comprises a control wheel set 10 . European Patent Application No. 3079024 by the same Applicant describes the operation of a magnetic actuator for the striking hammer (which is suitable for the present invention) in order to initiate or release the hammer's strike on the gong.

[0030] In a broad sense, "striking mechanism" refers to any clockwork mechanism that produces sound: a striking or alarm mechanism, music box, or other mechanism.

[0031] Such a hammer 1 compri...

Abstract

The invention relates to a timepiece chiming mechanism 100 including a mechanism for controlling a hammer 1 arranged to strike a resonant component 3 in an impact position PP, and movable within a working zone ZP between a recoil and rest position PR and this impact position, this mechanism includes a device for limiting recoil of the hammer 1 after impact, formed either by eddy current braking means arranged to brake the hammer 1 when it enters a back zone ZA, connected and contiguous to the working zone ZP and opposite the impact position PP, and / or by mechanical friction and / or elastic return means integral with the hammer 1 or an anchor-piece 11 integral with the hammer 1, and arranged for friction and / or abutting engagement with a moving braking component or a surface of a fixed partof the chiming mechanism 100.

Description

technical field [0001] The invention relates to a timepiece striking mechanism comprising a fixed part and a control mechanism arranged to directly or indirectly control the movement of at least one hammer comprising a hammer arranged to strike at least one resonating part or gong or The impact area of ​​the disc gong, the at least one hammer is movable in the working area between the recoil (recoil) and rest position and the impact position, in which the impact area and At least one resonant component is engaged. [0002] The invention also relates to a timepiece mechanism comprising such a striking mechanism. [0003] The invention also relates to a timepiece comprising such a timepiece mechanism and / or such a striking mechanism. [0004] The invention relates to the field of sounding timepiece mechanisms such as striking or alarm mechanisms, music boxes and the like. Background technique [0005] A timepiece striking or alarming mechanism usually includes a hammer whic...
