[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for accommodating a striking mechanism which is mounted in a watch case by screw fixing.

[0002]

2. Description of the Related Art Generally, a belling mechanism case has a cam, a motor, a number of bells detecting switch and the like housed therein, and a stem is swingably mounted therein, and is mounted on a watch case. At this point, the striking mechanism case is already blocked.

By the way, there are resin and wooden receiving plates of the watch case to which the above-mentioned bell-swing mechanism case is attached. Conventionally, a bell-swing mechanism case for each of the above-mentioned attachment objects is provided. It was prepared separately.

[0004]

Therefore, conventionally, the number of cases of the striking mechanism to be manufactured has increased, the number of parts has increased accordingly, and the management of these has been difficult.

Therefore, an object of the present invention is to provide a versatile striking mechanism case which can be applied to both a resin watch case support plate and a wooden watch case support plate.

[0006]

[Means for Solving the Problems] That is, the present invention is a case in which a bellows mechanism is housed and mounted in a timepiece case by screw fixing, and is composed of a front plate and a rear plate, and the both plates are fitted together. A mating plate that undergoes phase polymerization is provided on the surface, a boss swallowing space portion is provided on each of the opposite mating surface sides of both the mating plates, and a through hole portion that communicates with the both plates is formed at another portion of the space portion. A screw fastening plate is provided at one end of the through hole.

[0007]

In general, the mounting form differs depending on whether it is mounted on the resin receiving plate or the wooden receiving plate.
In the former case, a boss is previously formed on the receiving plate,
Attach the attachment to the boss and screw it. On the other hand, in the latter case, the mounting member is directly brought into close contact with the receiving plate and fixed by wood screws.

The striking mechanism case according to the present invention has a structure capable of coping with the difference in the above-mentioned mounting form.

That is, with respect to the receiving plate made of resin, the both mating plates are abutted against each other, and the boss previously formed in the receiving plate is inserted into the boss swallowing space of one boss, and the other boss is inserted. Insert the screw from the swallowing space and fix it to the receiving plate with the striking mechanism case.

On the other hand, with respect to the wooden receiving plate, the front plate and the rear plate are abutted and integrated with each other, the screw fixing plate is brought into close contact with the wooden receiving plate, and the wood screw is inserted into the through hole portion. Insert the bellows and fasten it to the receiving plate with screws.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing an embodiment. Although the striking mechanism case of the present embodiment is provided with two lobes, the present invention can of course be applied to a case with one lobe.

In the figure, 1 is a front plate, 2 is a rear plate,
A striking mechanism case A is constituted by the plates 1 and 2.
Reference numerals 3 and 3 respectively indicate Maki. B is a resin-made receiving plate for mounting the above-mentioned bell-swing mechanism case A, and a boss b is formed on the mounting surface of the resin-made receiving plate B. C is a wooden backing plate.

Then, a belling mechanism case A according to the present invention
Has a configuration that can be used for both of the receiving plates B and C.

More specifically, phase-matching laminated plates 11 and 21 are provided on the mating surfaces of the front plate 1 and the rear plate 2 respectively (see FIGS. 1 and 5), and the both laminated plates 11 and 21. A space 1 for swallowing the boss b on each of the opposite mating surfaces.
2 and 22 are provided, the front plate 1 and the rear plate 2 are superposed, and the boss b is swallowed into the space 22 on the rear plate 2 side so that the bell-swing mechanism case A is made of a resin receiving plate B. , And under this condition, insert a screw D into the space 12 of the front plate 1 to screw the above-mentioned both-matching plates 11 and 21 to the boss b (see FIG. 5). As shown in FIG. A usage mode in which the front plate 1 is closely attached to the resin receiving plate B can also be adopted. in this case,
The boss b is swallowed into the space 12 and the screw D is inserted from the space 22 side.

In addition, in the above-mentioned striking mechanism case A (in which the front plate 1 and the rear plate 2 are assembled), the other parts of the space portions 12 and 22 are provided so as to be easily attached to the wooden receiving plate C. , Through holes 13 and 23 communicating with the front plate 1 and the rear plate 2 are formed, and one end of the through holes 13 and 23 is screwed to one end (the mounting side of the rear plate 2 in the illustrated example). It is configured to have a mounting plate 24. In other words, the bellows mechanism case A is brought into close contact with the wooden receiving plate C (the screw fastening plate 24 is brought into close contact with the receiving plate C), and under this state, wood screws are inserted from the front plate 1 side to the through holes 13 and 23. Insert E and screw the bellows mechanism case A to the wooden support plate C (see FIG. 7).

As described above, the striking mechanism case A of the present invention
Is also a wooden support plate C for a resin support plate B.
Also easy to install.

In the illustrated embodiment, the space 12,
22 (in other words, the laminated plates 11 and 21) and the through hole portion 13,
23 are provided for each one on the upper part of the bell mechanism case,
In the present invention, the location and the number of locations are arbitrary.

[0018]

[Effects of the Invention] As described above, the bell-swing mechanism case of the present invention can be easily attached to both a resin receiving plate and a wooden receiving plate, and is commonly used for both receiving plates. As a result, the case can be provided with versatility, and the production planning and inventory management of parts can be labor-saving.
