Description

[Detailed Description of the Invention] Technical Field The present invention relates to a front pendulum timepiece, and particularly to an improvement in a front pendulum timepiece in which a pendulum is suspended and supported in a swingable manner on the front of the timepiece body, thereby increasing decorativeness.

PRIOR ART Despite the recent use of electronic clocks, classic pendulum clocks are preferred as table clocks or wall clocks, and pendulum clocks with built-in pendulums or decorative pendulums are widely used not only as timekeeping devices but also as a type of interior decoration. There is.

Also, as a type of pendulum clock of this kind, a front pendulum clock in which the pendulum swings from the front of the clock body is well known, and by having the pendulum swing from the front of the clock body, it is expected that a novel external design of the clock will be created. Can be done.

However, in conventional front pendulum clocks, a penetration part was provided in the clock body and the front pendulum was mechanically connected to the main pendulum so that the front pendulum swung on the front of the clock body, so the swing of the front pendulum caused the swing of the main pendulum. It was easily visible from the outside that the front pendulum clock was running in synchronization with the above, and as a result, despite the novel design of the front pendulum clock mentioned above, the overall appearance was relatively plain.

In addition, in conventional front pendulum clocks, the pendulum on the front of the watch body was mechanically interlocked with other decorative pendulums, making the mechanism for swinging the front pendulum complicated. This has the drawback of increasing the size of the device, and in particular, the increase in thickness due to the drive mechanism has the problem of greatly restricting the appearance of the watch.

Purpose of the invention The present invention was devised in view of the above-mentioned problems in the prior art. Our goal is to provide pendulum clocks.

Structure of the Invention In order to achieve the above object, the present invention includes a main oscillating rod body that is swingably supported on a watch body and in which a main pendulum engages, a driving magnet provided on the main oscillating rod body, and a driving magnet provided on the main oscillating rod body. a drive coil that is provided on the watch body and electromagnetically couples with the drive magnet to drive the main pendulum; a front oscillating rod body that is pivotally supported on the watch body and engages with the front pendulum that can swing freely in front of the watch dial; It is characterized by including an interlocking magnet fixed to the main vibrating rod body and the front vibrating rod body at positions facing each other and causing the front vibrating rod body to swing in accordance with the swinging of the main vibrating rod body by mutual magnetic force. .

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

1 and 2 show a preferred embodiment of the front pendulum timepiece according to the present invention, in which the timepiece body 10 is composed of a crystal clock. In this embodiment, the main pendulum 12
A decorative pendulum combination of a front pendulum 14 and a front pendulum 14 is shown, and the main pendulum 12 and front pendulum 14 are driven completely separately from the timekeeping function of the main body of the watch.

In the embodiment, the main pendulum 12 is longer than the front pendulum 14, and the main pendulum body 16 and the front pendulum body 18 are pivotably supported on the watch body 10, respectively.
is engaged with. Support bodies 20 and 22 are fixed to the upper ends of the swing rod bodies 16 and 18, and V grooves 20a and 20a provided on the lower surfaces of the supports 20 and 22,
22a is engaged with the knife edges 24 and 27 fixed to the watch body 10 described above, so that both the swinging rod bodies 16 and 18 are pivotally supported by the watch body 10 so as to be freely swingable.

The knife edge 27 is formed to protrude above the dial 25 provided on the front surface of the watch body, and as is clear from the figure, the front pendulum 14 swings in front of the watch dial.

A drive magnet 26 is fixed to the main oscillation rod body 16 in order to swing the main oscillation rod body 16 at a predetermined period, and a drive magnet 26 is fixed to the main oscillation rod body 16 at a predetermined position of the watch body 10 facing the drive magnet 26. The drive coil 28 is fixed, and due to the electromagnetic coupling between the drive magnet 26 and the drive coil 28, the main vibrating rod body 16, that is, the main pendulum 12
It can be driven swinging.

In the embodiment, an interlocking magnet 30 is fixed to the top of the support 20 fixed to the main swinging rod body 16, and a support fixed to the front swinging rod body 18 at a position facing the interlocking magnet 30. An interlocking magnet 32 is fixed to the body 22. Therefore, both interlocking magnets 3
A mutual magnetic force acts between 0 and 32, and this mutual magnetic force allows the front swinging rod body 18 to follow and interlock with the swinging of the main swinging rod body 16.

Therefore, according to this embodiment, there is no need to provide any device for magnetic coupling with the watch body 10 on the front pendulum body 18, that is, on the front pendulum 14 side, so that the front pendulum 14 does not receive any driving force. It is possible to give the user a mysterious feeling as if the rocking motion continues independently without any application of pressure.

In this embodiment, the pole arrangement of the magnets 30, 32 fixed to the supports 20, 22 can be arbitrarily selected, but if the pole arrangement is arranged in a manner in which different poles face each other as shown in FIG. 16 and 18, an in-phase movement occurs due to the attractive action of the magnets, and if the magnet 30 on the driving side moves to the left as shown by the solid arrow line in FIG.
That is, the magnet 32 on the front pendulum side also moves in the same direction,
Conversely, if the main drive side magnet 30 moves to the right, the front pendulum side magnet 32 also moves to the right as shown by the broken line.

Therefore, in a watch with magnets arranged with different polarities as shown in Fig. 3, both pendulums swing in the same phase;
When both the magnets 30 and 32 are arranged to face each other with the same polarity as shown in FIG. 16. The main swing rod body 18 will swing in the opposite direction.

In this embodiment, as shown in Fig. 1, by making a portion of the watch panel at the bottom of the watch dial transparent, the rocking motion of the main pendulum as well as the front pendulum can be seen from the outside. However, it is also possible to have a configuration in which only the front pendulum is visible without providing such a transparent part, and the main pendulum is simply used as a driving source for the front pendulum.

By configuring as above, the front pendulum 14
simply passes through the front swinging rod body 18 to the knife edge portion 24.
This creates the impression that the front pendulum clock is continuously swinging without using any driving force while suspended from the front pendulum clock, further enhancing the design effect of the front pendulum clock.

Effects of the invention As explained above, according to the invention, the main oscillation rod body is electromagnetically driven by a drive coil provided in the watch body, and the main oscillation rod body is driven forward by magnetic coupling with the main oscillation rod body. As a result of performing the oscillating motion of the oscillating rod body, the drive mechanism of the front pendulum itself is difficult for the user to discern, making it possible to provide novel and diverse design aspects of the front pendulum timepiece.
