Abstract

PURPOSE:To achieve a double oscillation effect of a time piece body and a pendulum by arranging a time piece body as first vibration system to oscillate with respect to the first pendulum fulcrum while a suspension member as second vibration system, an electromagnetic drive receiving plate and a supporting base oscillate with respect to the second pendulum fulcrum. CONSTITUTION:A time piece body 10 maintains an oscillatory motion with respect to the first pendulum fulcrum of a supporting base 20 by a electromagnetic drive force between a magnet 24 and a drive coil 26. A latch section as the second pendulum fulcrum is made up of a nail 30 fixed on a wall 28 and a suspension member comprises a chain 32 whose one end is hooked on the nail 30 while the other end thereof is fixed on an upper end 22a of an electromagnetic drive receiving plate 22. Then, the chain 32, the electromagnetic drive receiving plate 22 and the supporting base 20 compose the second vibration system. Therefore, the engagement of the nail 30 and the chain 32 enables the chain 32, the electromagnetic drive receiving plate 22 and the supporting base 20 to oscillate with respect to the nail 30 as the second pendulum fulcrum.

The platform swings relative to the second pendulum fulcrum, and the swing state changes depending on the position of the nonolancer.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a first embodiment of a double body swing timepiece according to the present invention, and FIG. 2 shows its cross section.

In FIGS. 1 and 2, the clock body 10 is swingably supported with respect to a first pendulum fulcrum.
A predetermined time is displayed on the dial 16 by the watch body 10, and a pendulum 18 that swings integrally with the watch body 10 is mounted at the bottom of the watch body 10. Fixed.

The hour hand body 10 and the pendulum 18 form a first vibration system.

The watch body 10 is swingably supported on a first pendulum fulcrum of a support base 20, and the knife groove 10m of the watch body 10 is supported by the groove 20a of the support base 20. Further, a plate 22 is protruded from the top of the support base 20, and a magnet 24 is fixed to the plate 22, and the magnet 24 and the electromagnetic force are fixed to the plate 22. A drive coil 26 that is coupled to generate swing driving force in the watch body 10
is fixed. Therefore, due to the electromagnetic driving force between the iron magnet 24 and the drive coil 26, the watch body 1O can maintain the rocking motion with respect to the first pendulum fulcrum of the support base 20.

In the present invention, a hanging member is provided, one end of which is hooked to a hook part serving as a second pendulum fulcrum, and the other end of which the electromagnetic drive amount is fixed to a plate, and the clock body and the pendulum serve as the first pendulum fulcrum. The hanging member, the electromagnetic driving amount is characterized in that the plate and the abutment swing relative to the second pendulum fulcrum, and in the first embodiment, the suspension member and the electromagnetic drive amount are The hanging part is attached to a nail 30 fixed to the wall 28, and the hanging member has one end hooked to the nail 30 and the other end fixed to the upper end 22a of the electromagnetic drive plate 22. It consists of a chain 32. A second vibration system is formed by the chain 32, the electromagnetic drive plate 22, and the support base 20. Therefore, the engagement between the nail 3o and the chain 32 allows the chain 32, the electromagnetic drive plate 22, and the support base 20 to swing relative to the nail 3o as the second pendulum fulcrum.

3 to 7 show the oscillating motion of the Ml embodiment, and from the figures, the first oscillating system, the clock body 1° and the pendulum 18
The chain 32, which is the second vibration system, the electromagnetic drive receiver swings relative to the support 20, and the plate 22 and the support 20 swing against the nail 3o.
It will be understood that the watch body 1o and the pendulum 18 thus perform a double swing.

As described above, according to the coffin 1 embodiment, the watch body 10 and the pendulum 18 swing relative to the support 2° as the first pendulum fulcrum, and the chain 32 and the electromagnetic drive receiver are connected to the plate 22 and the support. stand 2
o can swing relative to the nail 30 as the second pendulum fulcrum, so the watch body 10 and the pendulum 18 undergo a double swing 1. ：You can make, , j-use. therefore,
In the conventional m' body swing clock, the hour hand body and the pendulum only make a single simple swing with the same amplitude, but according to the present invention, the hour hand body 10 and the pendulum 1B have a double swing. By performing extremely complex rocking motions, it is possible to improve aesthetics and other qualities, resulting in an interesting watch.

In the present invention, the vibration periods of the first vibration system and the second vibration system can be set arbitrarily, but the vibration periods of the first vibration system and the second vibration system can be set almost the same, that is, both vibration systems are synchronized. By vibrating, it becomes possible for the user to maintain the vibration mode in which the watch was initially driven for a long period of time. However, of course, in the present invention, even if these two vibration systems are not brought into a synchronized state and the vibration periods of the two vibration systems are different, the vibration mode given initially changes sequentially over time. This makes it possible to realize various complex vibration modes as time passes, and even with such asynchronous double vibration, in actual use of the watch,
It is possible to present a separate aesthetic that is different from that of a synchronous double-oscillation clock.

In order to synchronize the double swing, it is sufficient to adjust the mass of both vibration systems or the distance from the pendulum fulcrum to the center of gravity. However, in the present invention, the distance from the second pendulum fulcrum to the first
The distance L from the first pendulum fulcrum to the pendulum 18
Distance to the center of gravity! By setting K (see FIG. 2) to approximately the same value, both vibration systems can be brought into a synchronous relationship, and it is preferable to set such a distance between the fulcrums as a clock.

In the first embodiment, the electromagnetic drive receiver has the plate 22 and the magnet 24 fixed thereon housed in the gap 34 between the watch mechanism section 12 and the dial side lower plate 14. The watch body 1O and the pendulum 18 can be swung without the plate 22 and the magnet 24 being exposed to the outside from the watch body 10. Further, the electromagnetic drive receiver can be operated from the back side of the timepiece mechanism section 12 (that is, the back side of the hour hand body 10) to adjust the time hand without being obstructed by the plate 22.
