Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double body clock, in particular to a double body clock having two vibration systems.

In recent years, full-body swing clocks in which the clock body itself swings about a pendulum fulcrum have been widely put into practical use for decorative purposes.

This type of full-body clock has a clock body swingably supported on a pendulum fulcrum of a support, and usually has a structure in which a knife edge of the clock body is supported in a V-groove of the support. The rocking motion of the watch body is maintained by the electromagnetic driving force between the drive coil or magnet provided on the watch body and the magnet or drive coil of the electromagnetic drive receiving plate provided on the base. I can do it.

However, in conventional full-body clocks, the clock body forms a single vibration system with respect to the base for rocking motion, and the problem is that the rocking of the clock body is simple. .

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to allow the watch body and pendulum to swing, as well as the hanging member, electromagnetic drive receiving plate, and support to swing, so that the watch body can be rotated in two directions. The purpose of the present invention is to provide a double body swinging clock that performs heavy swinging.

In order to achieve the above object, the present invention provides a timepiece body that is swingably supported with respect to a first pendulum fulcrum, a pendulum that swings together with the timepiece body that is fixed to the timepiece body, and a timepiece body that is fixed to the timepiece body. an electromagnetic drive receiver plate provided with a magnet or drive coil that is electromagnetically coupled with a drive coil or magnet provided on the watch body to generate swing driving force in the watch body; and a first pendulum fulcrum provided on the electromagnetic drive receiver plate. and a hanging member having one end hooked to a hook part serving as a second pendulum fulcrum and the other end fixed to the electromagnetic drive receiving plate, and the watch body and pendulum are attached to the first pendulum fulcrum. It is characterized in that the pendulum swings relative to the pendulum fulcrum, and the hanging member, the electromagnetic drive receiving plate, and the support stand swing relative to the second pendulum fulcrum.

Further, the present invention provides a timepiece body that is swingably supported with respect to a first pendulum fulcrum, a pendulum that is fixed to the timepiece body and swings together with the timepiece body, and a drive coil or a drive coil provided on the timepiece body. an electromagnetic drive receiving plate provided with a magnet or a drive coil that is electromagnetically coupled with a magnet to generate swing driving force in the watch body; an abutment serving as a first pendulum fulcrum provided on the electromagnetic driving receiving plate; and one end. a hanging member that is hooked to a hooking portion serving as a second pendulum fulcrum and whose other end is fixed to the electromagnetic drive receiving plate; and a balancer that is adjusted and fixed to the hanging member and is movable in the vertical direction. The clock body and the pendulum swing relative to the first pendulum fulcrum, and the suspension member, electromagnetic drive receiving plate, and abutment swing relative to the second pendulum fulcrum, depending on the position of the balancer. It is characterized by a change in the swing state.

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

FIG. 1 shows a first embodiment of a double-body clock according to the present invention, and FIG. 2 shows a cross section thereof.

In FIGS. 1 and 2, a watch body 10 that is swingably supported with respect to a first pendulum fulcrum has a watch mechanism section 12 and a dial-side lower plate 14 therein, and the watch body 10 is provided with The time is displayed on the dial 16, and a pendulum 18 that swings together with the clock body 10 is suspended and fixed to the lower part of the clock body 10.
The clock body 10 and the pendulum 18 form a first vibration system.

The timepiece body 10 is swingably supported about a first pendulum fulcrum of a support base 20, and a knife edge 10a of the timepiece body 10 is supported in a V-groove 20a of the support base 20. Further, an electromagnetic drive receiving plate 22 is protruded from the upper part of the support base 20.
A magnet 24 is fixed to the watch body 10 , and a drive coil 26 is attached to the watch mechanism section 12 of the watch body 10 , and the drive coil 26 is electromagnetically coupled to the magnet 24 to generate swing driving force in the watch body 10 .
is fixed. Therefore, due to the electromagnetic driving force between the magnet 24 and the drive coil 26, the watch body 10 can maintain its swinging motion about 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 fixed to the electromagnetic drive receiving plate, so that the clock body and the pendulum are attached to the first pendulum fulcrum. As well as swaying against the
The suspension member, the electromagnetic drive receiving plate, and the support are characterized in that they swing relative to the second pendulum fulcrum, and in the first embodiment, the hanging portion serving as the second pendulum fulcrum is attached to the wall 28. The hanging member has one end hooked to the nail 30 and the other end attached to the upper end 22a of the electromagnetic drive receiving plate 22.
It consists of a chain 32 fixed to. And chain 32,
The electromagnetic drive receiving plate 22 and the abutment 20 form a second vibration system. Therefore, nail 30 and chain 3
2, the chain 32 and the electromagnetic drive receiving plate 2
2 and the abutment 20 are a nail 3 as a second pendulum fulcrum.
It can be oscillated relative to 0.

3 to 7 show the oscillating motion of the first embodiment, and from the figures it can be seen that the watch body 1 which is the first vibration system
0 and the pendulum 18 swing relative to the base 20, and the chain 32, which is the second vibration system, the electromagnetic drive receiving plate 22, and the support base 20 swing relative to the nail 30, and as a result, the watch body It will be appreciated that 10 and pendulum 18 perform a double swing.

0, and the chain 32, electromagnetic drive receiving plate 22, and pedestal 20 can also swing relative to the nail 30 serving as the second pendulum fulcrum, so the watch body 10 and the pendulum 18 are Can perform heavy swinging operations. Therefore, in the conventional integrated clock, the clock body and the pendulum only make a single simple swing with the same amplitude, but according to the present invention, the clock body 10 and the pendulum 18 have a double swing. Therefore, it is possible to perform extremely complex rocking motions, improve aesthetics and other qualities, and obtain interesting watches.

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 are set to almost match, that is, the two vibration systems are synchronized. By causing the watch to vibrate, it becomes possible to maintain the vibration mode in which the user originally gave the initial drive to the watch over 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 will fluctuate sequentially over time. As a result, it is possible to realize various complex vibration modes over time, and in actual use of the watch, a double vibration clock that is in an asynchronous relationship becomes a double vibration clock that is in a synchronous relationship. It becomes possible to present a separate sense of beauty that is different from the above.

In order to bring the double swing into a synchronous relationship, it is sufficient to adjust the mass of both vibration systems or the distance from the pendulum fulcrum to the center of gravity, but in the present invention, the distance from the second pendulum fulcrum to the first Distance L to
Distance l from the first pendulum fulcrum to the center of gravity of the pendulum 18
(See FIG. 2) can be set to substantially the same value to bring both vibration systems into a synchronous relationship, and it is preferable to set such a distance between the fulcrums as a clock.

In the first embodiment, since the electromagnetic drive receiving plate 22 and the magnet 24 fixed thereto are housed in the gap 34 between the timepiece mechanism section 12 and the dial side lower plate 14, the electromagnetic drive receiving plate The watch body 10 and the pendulum 18 can be vibrated without substantially exposing the watch body 22 and the magnet 24 to the outside of the watch body 10. Further, time hand setting, etc., which is operated from the back surface of the timepiece mechanism section 12 (that is, the back surface of the timepiece body 10), can be performed without being hindered by the electromagnetic drive receiving plate 22.

Next, FIG. 8 shows a second embodiment of a double-body clock according to the present invention, and FIG. 9 shows a cross section thereof.
