Embodiment Construction

[0052] Within the scope of the present invention the term "ratchet" (except for the ratchet of the barrel) is extended to all toothed parts of a pallet for driving one or more bell hammers.

[0053] refer to Figure 1 to Figure 4 A chime mechanism according to a preferred embodiment of the invention for integration or addition to a movement of a timepiece, typically a watch, comprises in a base 1 a chime gear 2 connecting an energy source 3 with a regulator 4 . The energy source 3 is typically a bell barrel, which abuts against the wheel 2 a of the bell gear 2 and which can be wound by turning the winding rod 5 . The winding rod 5 is preferably the winding rod of the movement, also serving to wind the barrel of the movement. The regulator 4 is, for example, a centrifugal regulator (watt regulator). It is used to adjust the tapping speed (tempo) that needs to ring the bell. A clutch rocker arm 6 pivoting about an axis 7 supports two pinions 8 and 9 which rotate relative to t...

Abstract

The striking mechanism comprises at least one gong (29, 30), an actuating device (11, 20-28, 31-62) for actuating the gong(s), a striking barrel (3), a clutch device with a lever (6) for coupling the actuating device (20-28, 31-62) to the striking barrel (3), the lever (6) of the clutch device being arranged to pivot between a first position in which the actuating device (20-28, 31-62) is coupled to the striking barrel (3) and a second position in which the actuating device (20-28, 31-62) is uncoupled from the striking barrel (3), and a blocking device (18) for blocking the striking barrel (3). The blocking device comprises a blocking member (18) rigidly connected to the lever (6) and arranged so as to block the striking barrel (3) when the lever (6) is in the second position and to not block the striking barrel (3) when the lever (6) is in the first position.

Description

technical field [0001] The present invention relates to a chime mechanism for a timepiece, such as a wristwatch or pocket watch. The chime mechanism is, for example, a chime mechanism that repeats every minute or longer. [0002] The invention relates more particularly to a chime mechanism comprising at least one bell, means for driving the bell, a chime barrel, clutch means with rocker arms for connecting the driving means to the chime barrel, clutch The rocker arm of the device is arranged to pivot between a first position in which the drive means is connected to the bell barrel and a second position in which the drive means is disconnected from the bell barrel, and for locking the bell barrel Locking device. Background technique [0003] Such a bell mechanism is described in the patent application EP 1760554 . In this patent, the drive consists of three hour, quarter and minute rakes or hour, quarter and minute ratchets, which drive the pallet fork, which itself drives...
