DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a full swing timepiece 1, particularly to a full swing timepiece in which the timepiece body itself swings.

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.

In this full-body seconds clock, the clock body is swingably supported on a pendulum fulcrum of a fixed support, and in normal cases, the knife of the clock body is supported in the V-groove of the fixed support. Become. The oscillating 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 on the fixed support plate. I can do it.

However, in such conventional comprehensive swing training, the plate of a fixed receiver equipped with a magnet or a driving coil is located outside the time division body, for example, the plate of a fixed receiver is fixed to a wall, or The holder held by the pedestal Donaru Goddess statue etc. is made of a plate, and the fixed holder (j plate is exposed outside the clock body. Therefore, when the time division body swings, the fixed holder is connected to the plate and magnet or drive coil. There was a problem in that this was visible to the user, significantly detracting from the appearance of the h1.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to store a small pendulum inside a watch body, change the center of gravity position of the hour 31 body by the rocking of the small pendulum, and create a fixed receiver. The object of the present invention is to provide a comprehensive photographic timepiece in which a timepiece body swings without exposing a 1:6 movement mechanism such as a plate or a magnet to the outside.

In order to achieve the above object, the present invention provides a watch body, etc., which is supported swingably about a pendulum fulcrum and has a time display section.
A small pendulum is housed inside the watch body and changes the position of the center of gravity of the watch body, and a small pendulum is provided on the small pendulum. c) A drive coil or magnet provided on the watch body, a small pendulum detection means for detecting the position of the small pendulum, and a drive coil or magnet provided on the watch body and a small pendulum by the small pendulum detection means.
a small pendulum drive circuit that operates A2 when it detects that the magnet or the drive coil has come to an opposing position, and excites the drive coil to swing the small pendulum; The pendulum consists of a swinging rod body which is swingably supported by A pair of swing regulation pins are installed that restrict the swing of the small pendulum to a range smaller than the maximum amplitude when the pendulums collide. The center of gravity of the hour 81 body is changed to cause the hour 81 body to swing, and the repulsive force when the small pendulum collides with the swing regulating bottle is absorbed by the swing of the weight against the shaking rod body, causing the small pendulum to swing. The small pendulum contacts the swing regulating bottle and follows the tilting movement of the time division body until the movement of the timepiece body reaches its maximum amplitude.

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

FIG. 1 shows a preferred embodiment of a full-body camera watch according to the present invention, and FIG. 2 shows a side view of the watch body.

The time division body 10, which is shown at J5 in FIG. 1.2 and is supported so as to be swingable about the pendulum fulcrum, has a time display section 12 that displays a predetermined time on its upper part, and a time display section 12 on its lower part. Part 12
It has a pendulum 14 that swings together. The time 81 body 10 is swingably supported about the pendulum fulcrum of the identification support 16, and the knife 10a of the time division body 10 is supported in the V-groove 16a of the fixed support 16.

A characteristic feature of the present invention is that a small pendulum is housed inside the hour if body, and the swing of the small pendulum changes the center of gravity position of the watch body, causing the time body to swing. In the embodiment, a small pendulum 20 that swings about a small pendulum support shaft 18 is housed inside the watch body 10. As shown in FIG. 1, when the small pendulum 20 swings in the direction of arrow A1, the time division body 10 swings in the direction of arrow B1 due to a change in the center of gravity of the timepiece body 10, and When the small pendulum 20 swings in the direction of arrow A2, the time sharing body 10 swings in the direction of arrow B2 due to a change in the center of gravity of the timepiece body 10.

Therefore, the position of the center of gravity of the timepiece body 10 can be changed by the rocking of the small pendulum 20, and the rocking motion of the timepiece body 10 can be maintained.

Next, the structure for swinging the small pendulum 20 will be explained.

In FIG. 1.2, the time display section 12 includes a lower plate 22, and the small pendulum 20 is swingably supported by a small pendulum support shaft 18 whose one end is fixed to the lower plate 22. In order to apply swing driving force to the small pendulum 20, a magnet 24 is provided on the small pendulum 20, and a drive coil 26 is provided on the watch body 10.

That is, a magnet 24 is fixed to the lower end of the small pendulum 20,
A drive coil support plate 30h is provided on the lower plate 22 via drive coil support columns 28a128b, and a drive coil 26 that is electromagnetically coupled to the magnet 24 is fixed to the drive coil support plate 30. 24 and a drive coil 26 provided corresponding to the magnet 24, the small pendulum 2
The swing driving force will be applied to 0.

In order to swing the small pendulum 20, it is necessary to excite the drive=1 coil 26 as soon as the small pendulum 20 passes the drive coil 26, and it is necessary to detect the passage of the small pendulum 20. be. Therefore, in the present invention, a small pendulum detection means for detecting the position of the small pendulum is provided. Consists of.

FIG. 3 shows a small pendulum drive circuit for swinging the small pendulum 20. In the figure, the C1 detection coil 34 is connected between the pace and emitter of the amplification transistor 36, and the drive coil 2G is connected between the collector and emitter of the amplification transistor 36. can be detected, and the swinging motion of the small pendulum 20 can be maintained. Zunawara, small pendulum 2
0 swings to the left or right and comes off the detection coil 34, the detection current 100 is not generated in the detection coil 34, so the drive coil 26 is not excited and the small pendulum 20
When the current passes through the detection coil 34, a detection current 100 is generated in the detection coil 34 due to the passage of the magnet 24 fixed to the small pendulum 20, and a drive current 102 is generated in the drive coil 26.
flows. As a result, the drive coil 26 is excited, and the small pendulum 20 continues to swing.

As described above, in the embodiment, the position of the small pendulum 20 is detected by the detection coil 34, and the drive coil 26 is excited when the small pendulum 20 passes the drive coil 26. Since a swinging driving force is generated in the small pendulum 20 by the electromagnetic coupling between the drive coil 26 and the magnet 24, the swinging motion of the small pendulum 20 can be maintained.

Here, the period of the clock body 10 and the period of the small pendulum 20 are the first
As is clear from the figure, the period of each body 10 is longer and the period of the small pendulum 2o is shorter. For this reason, the small pendulum 20 is moved according to the natural period of the small pendulum 20 (oscillation C
The small pendulum 20 began to swing faster, and at 51
It is not possible to swing the body 1o.

Therefore, it is necessary to make the period of the small pendulum 20 coincide with the period of the clock body 1o, and in the present invention, the small pendulum 20 collides with the small pendulum 2° before the small pendulum 20 reaches the maximum amplitude, so that the small pendulum A pair of swing regulating pins 38a and 38b that regulate the swing of 2o to a range sufficiently smaller than the maximum amplitude are KQL.
I'm getting fucked. Then, the small pendulum 20 is positioned in contact with its swing core swing regulating pins 38a and 38b, and when
The small pendulum 2o contacts the swing regulating pins 38a and 38b and follows the tilting of the body 1o until the swing of the body 1o reaches its maximum amplitude, so the period of the small pendulum 2o is changed to the period of the body 1o. Can be matched. Furthermore, the small pendulum 20 is comprised of a oscillating rod body 44 which is pivotally supported on the clock body 10 and is swingably held on the oscillating rod body 40 via an M fitting arm 42. , when the small pendulum 20 collides with the swing regulating pins 38a, 38b, the small pendulum 2o
Return due to repulsion can be prevented. That is,
When the small pendulum 20 collides with the swing regulating pins 38a and 38b, the repulsive force at the time of the collision is absorbed by the swing of the peg 44 against the swinging rod body 4o, thus preventing the small pendulum 2° from returning 1)
I can do it.

Therefore, the period of the small pendulum 2o can be matched with the period of the clock 1o by the swing regulating pins 38a, 38b and the shaft 44, and the swing of the hour body 1o becomes possible.

Next, the swinging operation of the small pendulum 20 will be explained in detail based on the drawings.

FIG. 1 shows the small pendulum 20 in a resting state, and the pendulums 4 to 8
The figure shows the swinging state of the small pendulum 2o.

In FIG. 1, the small pendulum 2o and the hour 81 body 1o are stationary, and when the drive coil 26 is excited from this stationary state, the small pendulum 2o swings in the direction of arrow A2. As the small pendulum 2o swings in the A2 direction, the center of gravity of the timepiece body 10 changes, and the hour body 10 swings in the arrow B2 direction.

In FIG. 4, the small pendulum 20 is swinging in the direction of the arrow Ch, and due to the change in the center of gravity of the time body 10, the time body 10 is
swings in the direction of arrow Dh.

In FIG. 5, the small pendulum 20 is positioned in contact with the swing regulation bin 38a, and the collision of the small pendulum 20 with the swing regulation bin 38a restricts the swing of the small pendulum 20 to a range smaller than the maximum amplitude. .

FIG. 6 shows a weight that absorbs the repulsion of the small pendulum 20 when the small pendulum 20 collides with the swing regulating bottle 38a, prevents the small pendulum 20 from returning, and maintains the contact position of the small pendulum 20. 44. FIG. In the figure, when the small pendulum 20 collides with the swing regulation bottle 388, the weight 44 appears on the swing rod body 40 and swings in the direction of the arrow C. The repulsive force of time is absorbed, and the small pendulum 20 is prevented from returning in the direction of the arrow.

In FIG. 7, the small pendulum 20 contacts the swing regulating bin 38a and follows the tilting of the clock body 10 until the swing of the watch body 10 in the direction of the arrow G reaches its maximum amplitude.

Therefore, the period of the small pendulum 20 can be made to match the period of the hour body 10.

Then, sometimes after the swing of one body 10 reaches its maximum amplitude,
The small pendulum 20 and the time ff1 body 10 begin to return, and the small pendulum 20
When the current passes through the detection coil 34, the drive coil 26 is excited. When the drive coil 20 is excited, the drive coil 26
Due to the electromagnetic coupling between the magnet 24 and the small pendulum 20
A direction shooting driving horn is generated.

In FIG. 8, the drive coil 26 and the magnetic? Due to the electromagnetic coupling with i24, the small pendulum 20 receives a swing driving force in the direction of arrow 1, and the swing of the small pendulum 20 changes the center of gravity position of the watch body 10. Therefore, the watch body 10 moves in the direction of arrow J. Thereafter, the same action as shown in FIG. 4 is performed.

As described above, the swinging motion of the small pendulum 20 can be understood from FIGS. 1.4 to 8. That is, the position of the small pendulum 20 is detected by the detection coil 34, and when the small pendulum 20 passes the detection coil 34, the drive coil 26 is excited, and the electromagnetic coupling between the drive coil 2G and the magnet 24 causes the small pendulum 20 to swing. Since the driving force is generated, the swinging motion of the small pendulum 20 can be maintained. Furthermore, the swing regulation bin 38a138b
Since the small pendulum 20 is prevented from returning by the weight 44, the period of the small pendulum 20 can be adjusted to match the period of the temporal body 10, making it possible to swing the temporal body 10.

As explained above, according to the total swing clock according to the present invention, a small pendulum is housed inside the timepiece body, and the center of gravity of the four hour bodies is changed by the swing of the small pendulum, and the hour eighty-one body is oscillated. can be moved. Therefore, the fixed receiver allows the watch body to swing without exposing the swinging mechanisms such as plates and magnets to the outside. Furthermore, since the swing mechanism is all housed within the timepiece, there is no need to provide a plate for the fixed receiver on the back of the watch body, reducing design constraints.
