Description

[Detailed Description of the Invention] This invention relates to a separation prevention structure for a full-body swing timepiece in which a swing body to which a movement is attached is swung relative to a support.

Generally, in a full-body swing clock, a support body is placed and fixed on a fixed member such as a wall, a pillar, a shelf, or a stand, and a swing body with a time display section is swingably supported on a support part that protrudes from the support body. It is something to do. That is, the supporting portion is provided with a concave bearing such as a pivot bearing, the swinging body is provided with a sharp pivot support such as a pivot, and the pivot support is engaged with the concave bearing for support. The swing body is provided with a movement, a battery, and a time display section, and its swing is caused by the magnetic action of a magnet provided on the support and a drive coil provided on the swing body.

In the case of conventional full-body clocks, the pivot support was simply placed on a concave bearing. Therefore, the structure is such that the support body and the swinging body can be easily separated, and there is a risk that the swinging body may separate from the support body and fall due to unexpected force. This meant that it could not be installed in a high place, and in reality it was limited to general swing clocks as table clocks, so its range of use was narrow and it was not possible to use it effectively.

This invention was made in view of the above circumstances, and has the purpose of providing a separation prevention structure for a full-body swing clock that enables the emergence of a full-body swing clock as a wall clock that can be installed in a high place.

Therefore, in order to achieve the above object, the separation prevention structure of the overall swing clock according to this invention has a separation distance within a range where the concave groove of the pivot bearing and the sharp shaft support of the pivot do not come out of engagement. A regulating stopper is removably fixed to either one of the support part and the swinging body located below the engagement position of the concave groove part and the shaft support part.

Embodiments of this invention will be described in detail below based on the drawings.

FIG. 1 is a front view of the full-body swing clock with the front plate removed, and FIG. 2 is a central vertical sectional view of the full-body swing clock. In the figure, reference numeral 2 is a support body, and 4 is a swinging body.
The base plate part 12 of the support body 2 has a plate shape, and a hook part 6 is provided at the center of the upper end thereof. The hook part 6 is hung on the head of a fixture 10 of a wall 8, which is a fixture member. A support part 14 is provided to protrude forward from the base plate part 12 of the support body 2, and two pivot bearings 16, which are concave bearings, are provided on the upper surface of the support part 14. A pivot 18, which is a shaft support of the swinging body 4, is engaged with the pivot bearing 16, and the swinging body 4 is supported so as to be swingable.

The swing body 4 has two pivots 18 above it.
are fixedly installed so as to engage with the pivot bearings 16, respectively. Further, in consideration of the overall balance, a battery storage section 20 is provided in the center of the swinging body 4, and a movement 22 is provided below. A front plate 24 having a time display section is attached to the front of the swinging body 4, and a pointer pipe 2 passes through the front plate 24.
A pointer (not shown) is attached to 6.

A guide groove 27 is provided on the back of the battery storage section 20 of the swinging body 4.
is provided, and the stopper 28 can be fixed in a detachable manner from the front of the swinging body 4. This stopper 28 is for regulating the separation distance between the pivot bearing 16 and the pivot 18 that occurs when the swinging body 4 is lifted, and is thick enough to regulate the distance without the pivot 18 coming off the pivot bearing 16. It is shaped like a piece of wood. The stopper 28 is the battery storage part 2
The swing body 4 is disposed between the back part of the swing body 4 and the support part 14, and a slight gap is provided between the support part 14 and the stopper 28 to provide a degree of freedom that does not hinder the movement of the swing body 4.

In the above embodiment, the concave bearing for supporting the swinging body 4 is the pivot bearing 16, and the pivot support is the pivot 18. However, the present invention is not limited to this configuration, and the shaft support may be formed into a knife edge, and the concave bearing may be formed into a V-shaped groove or a groove in cross section and engaged with the knife edge. In this case, the stopper installed between the support part and the swinging body may have a thickness to the extent that the knife edge does not come off the V-groove or groove.

Further, in the above embodiment, the stopper 28 is fixed to the swinging body 4 in a detachable manner, but it is of course possible to fix it to the support part 14. The reason why the stopper is detachably fixed is to allow the support body and swing body to be separated during transportation or repair.

Next, the operation of the total swing clock according to this invention will be explained. A swing body is supported on the support part of the support body which is suspended and fixed to a fixed member such as a wall, and although not shown, the swing body is swung by the magnetic action of the magnet provided on the support body and the drive coil provided on the swing body. A rocking force is applied to the body. The swinging body swings smoothly due to the engagement between the concave bearing with low frictional resistance and the sharp shaft support. Now, when the swinging body is lifted by some force, the pivoting part lifts up, and before the pivoting part is removed from the concave bearing, the stopper comes into contact with the support body or the swinging body, and the lifting of the pivoting part is prevented. Therefore, the pivot support does not come off the concave bearing, and the swinging body cannot be separated from the support.

As explained above, according to this invention, by providing the stopper on either the support part or the swinging body, the swinging body will not be separated from the support, and a full-body swinging clock as a wall clock will appear. I can do it. In addition, the stopper can be easily removed manually during repairs, etc., making the work easier.

In addition, since the stopper is provided inside the swing body,
This has the advantage that the user does not need to remove the stopper unnecessarily, which reduces malfunctions, and the stopper is not visible from the outside, resulting in a good appearance.

Claims (1)

[Scope of utility model registration request] In the general swing clock, a stopper that regulates the separation distance between the concave groove of the pivot bearing and the sharp shaft support of the pivot within a range that does not disengage the concave groove of the pivot bearing, etc. is placed between the engagement position of the concave groove and the shaft support of the pivot. A separation prevention structure for an all-in-one swing clock, characterized in that it is detachably fixed to either one of a lower support part and a swing body.
