【Example】

 As shown in FIG. 1 to FIG. 3, a dial 2 is fixed to the back of a frame 1 of a timepiece and is formed in the recess of the time display portion 1a. A pointer shaft 4 penetrates through the dial 2 and projects to the front from a timekeeping movement 3 mounted on the back of the dial 2, and a pointer 5 is attached to the projecting end. At the time display position on the outer peripheral portion of the front face of the dial 2, twelve rotating decorative plates 7 ... Simulating the shape of gears are rotatably provided. The front of each rotating decorative plate 7 starts from "1". Displayed characters 6 ... are written up to "12".

Another rotating decorative plate 8 is provided below the pointer shaft 4, and a human-shaped movable decorative member 9 is swingably provided beside the decorative plate 8.

As shown in FIG. 3, a support plate 10 is fixedly attached to the rear surface of the dial plate 2 at a predetermined interval. The support plates 10 for driving the rotary decoration plates 7 ... The train wheel 20 is located. As shown in FIGS. 3 and 4, the train wheel 20 has six large gears 21 ... And six small gears 22 ... which are concentric with the rotary decoration plates 7 ... and a concentric position with the rotary decoration plate 8. It is composed of one gear 23 in the. The gear ratio of the large gear 21 and the small gear 22 is 2: 1. In this embodiment, the large gear 21 corresponds to the even number and the small gear 22 corresponds to the odd number alternately. The gears are positioned and meshed with each other, and the meshing between the large gear 22 and the small gear 21 corresponding to the positions of 11:00 and 12:00 is broken. Further, the gear 23 meshes with the large gear 21 at the 6 o'clock position. The central shafts 21a, 22a and 23a of the respective gears are rotatably supported by the dial plate 2 and the support plate 10, and at the protruding ends of the central shafts 21a, 22a and 23a from the dial plate 2, a rotary ornament is attached. Plates 7 ... and 8 are fixed to each other. A decorative drive movement 24 is fixed to the back of the support plate 10, and a central shaft 21a of the large gear 21 at the 6 o'clock position serves as an output shaft of the decorative drive movement 24.

A mechanism for swinging the movable ornament (doll) 9 by the gear 23 that is interlocked with the rotation of the large gear 21 at the 6 o'clock position will be described. As shown in FIGS. 4 to 8, a star-shaped cam 23b is concentrically formed integrally with the gear 23. A movable lever 25 extending toward the cam 23b is swingably supported by the support plate 10 via a shaft 25a.

As shown in FIGS. 5 and 6, an engaging pin 25b that can engage with the cam 23b is integrally provided on the front side of the cam-side tip of the movable lever 25. A locking groove 25c is provided at the other end of the movable lever 25. A spring 26, which is a movable lever urging means, is hooked on the locking groove 25c, and urges the movable lever 25 with a counterclockwise spring force to elastically contact the engagement pin 25b with the cam 23b. The movable lever 25 is made to follow the cam 23b. A lock pin 25d that fits into a long groove 10a provided in the supporting plate 10 is integrally provided on the rear surface of the movable lever 25 on the cam side. The long groove 10a has an arc shape centered on the shaft 25a, and allows the movable lever 25 to swing about the shaft 25a.

The doll-shaped movable ornament 9 has its upper body swingably supported by a support plate 10 via a shaft 9 a penetrating the dial 2. A mechanism for transmitting the swing of the movable lever 25 to the movable ornament 9 will be described. As shown in FIG. 5 to FIG. 8, a pin 9b integrally protrudes from the movable ornament 9 toward the back, and the pin 9b penetrates the long groove 2a provided in the dial 2 to move the movable lever. It is fitted in the long groove 25e of 25. The long groove 2a has an arc shape centering on the shaft 9a, and allows the movable ornament 9 to swing about the shaft 9a. Further, since the gap between the long groove 25e and the pin 9b is made extremely small, the swing of the movable lever 25 is reliably transmitted to the movable ornament 9. The legs 9c of the doll are fixed to the front surface of the dial 2.

As shown in FIGS. 9 and 10, as a mechanism for restricting the swing of the movable lever 25, a locking projection 10b as a restriction means is provided in a part of the long groove 10a. As shown in FIG. 9, when the lock pin 25d is locked to the locking projection 10b, the engagement pin 25b is held at a position separated from the cam 23b, and the swing of the movable lever 25 is restricted.

As a mechanism for releasing the regulation of the movable lever 25 in the swinging regulation state and automatically returning to the swingable state, a return cam 23c as a releasing means is projectedly provided on the back side of the gear 23. .. The relative positional relationship between the two is set so that the engagement pin 25b in the swing-restricted state is positioned in the movement locus of the return cam 23c due to the counterclockwise rotation of the gear 23.

With such a structure, at the hour, for example, 10 o'clock, a time signal such as a melody is played, and the hour signal is supplied to the movement 24 for decoration drive, which serves as a drive axis. The central shaft 21a at the time position rotates, and all the large gears 21 and the small gears 22 in the train wheel 20 rotate. Further, since the gear ratio of the small gear 22 is 1/2 that of the large gear 21, the small gear 22 rotates twice while the large gear 21 makes one rotation. By this rotation, among the rotating decorative plates 7, ..., the even decorative plate 7 is rotated clockwise once, and the odd decorative plate 7 is rotated counterclockwise twice. .. Further, the gear 23 rotates in conjunction with the large gear 21 at the 6 o'clock position, and rotates the rotary decoration plate 8 counterclockwise. Then, as shown in FIG. 5, the engaging pin 25b elastically contacts and slides on the troughs and peaks of the cam 23b, and the movable lever 25 thereby repeatedly swings about the shaft 25a. This swinging motion is transmitted to the movable decoration 9 via the pin 9b, and the upper body of the movable decoration 9 is swung left and right. Since the hand portion of the movable ornament 9 is extended toward the rotary ornament plates 8, this swinging motion to the left and right makes it look as if the doll is turning these rotary ornament plates 8 and 7.

When the timepiece is transported, the movable lever 25 is manually swung clockwise, so that the lock pin 25d is locked by the locking projection 10b as shown in FIG. Is held, the movable lever 25 does not sway. When the user starts the use, the gear 23 rotates counterclockwise in FIG. 10 at the hour even if the swing restriction state is not canceled or the driver forgets to cancel it. Engages with and pushes the engagement pin 25b, swings the movable lever 25 counterclockwise, disengages the lock pin 25d from the locking projection 10b, and the engagement pin 25b elastically contacts the cam 23b. The state, that is, the state shown in FIG. 5, is automatically restored. After that, the above complicated exercise is repeated every hour.

In the above-mentioned embodiment, the hour movement signal is supplied from the movement 3 for clocking to the movement 24 for decoration driving, but the invention is not limited to this, and any time such as alarm time may be set. The time signal may also be supplied.

The movable ornament 9 is not limited to the one that is oscillated and driven only on the hour, and may be configured to be oscillated and driven at all times. In this case, the swinging restriction releasing means may be configured to be driven when the power is turned on. Further, the gear 23 is meshed with the gear 21 and interlocked with the train wheel 20, but the gear 23 is not limited to this, and may be separated from the train wheel 20 and rotationally driven by another driving means. In that case, an appropriate rotating wheel is used in addition to the gear.

[Effect of the device]

 As described above, the timepiece with the movable decoration of the present invention, in addition to the usual time signal sound and melody sound at the time of the hour, for example, causes each of the rotary decoration plates at the time display position to rotate in a complicated manner. As it becomes a fun and dreamy clock and has a simple structure, it can be offered at low cost and has the effect of meeting the needs of consumers.
