Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case that houses a bell-driving mechanism and is mounted in a watch case by screwing.

[0002]

[Prior Art]

 Generally, a bell mechanism case has a cam, a motor, a number-of-belts detection switch, and the like housed inside, and a stem is swingably mounted. The striking mechanism case is already blocked.

By the way, there are two types of receiving plates of the watch case to which the belling mechanism case is attached, one made of resin and the other one made of wood. Conventionally, the belling mechanism case for each of the attachment objects is used. Was prepared separately.

[0004]

[Problems to be solved by the device]

 Therefore, in the past, the number of cases with a striking mechanism that had to be manufactured increased and the number of parts also increased, and the management of these cases was difficult.

Therefore, the present invention aims to provide a belling mechanism case having versatility, that is, capable of responding 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 striking mechanism is housed and mounted by screw fixing in a watch case, which is composed of a front plate and a rear plate, and a mating plate that overlaps with the mating surface of each of the both plates. A boss swallowing space is provided on each of the opposite mating surface sides of the both facing plates, and a through hole communicating with the both plates is formed at another place of the space. It is configured such that a screw fastening plate is provided at one end.

[0007]

[Action]

 Generally, the mounting form differs depending on whether it is mounted on a resin backing plate or a wooden backing plate. In the former case, a boss is formed in advance on the receiving plate, and an attachment is applied to the boss to fix it with screws. On the other hand, in the latter case, the mounting member is attached directly to the receiving plate and secured with 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 a resin-made receiving plate, the both mating plates are abutted against each other, and a boss previously formed on the receiving plate is inserted into one of the boss-swapping spaces, 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, and the screw fixing plate is closely attached to the wooden receiving plate, and the wooden screw is attached to the through hole portion. Insert and screw the bellows mechanism case to the back plate.

【Example】

 Hereinafter, the present invention will be described with reference to the accompanying drawings illustrating an embodiment. Although the striking machine structure case of this 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, and both the plates 1 and 2 constitute a striking mechanism case A. Reference numerals 3 and 3 respectively indicate Koki. B is a resin-made receiving plate to which the bell-bell mechanism case A is attached, and a boss b is formed on the attaching surface of the resin-made receiving plate B. C is a wooden backing plate.

The striking mechanism case A according to the present invention has a structure that can be used for both the receiving plates B and C.

Specifically, on the mating surfaces of the front plate 1 and the rear plate 2, respectively, mating plates 11 and 21 which are phase-polymerized with each other are provided (see FIGS. 1 and 5 to 7). Spaces 12 and 22 for swallowing the boss b are provided on the opposite mating surface sides, respectively, and the front plate 1 and the rear plate 2 are superposed to form a space 22 on the rear plate 2 side. The boss b is swallowed and the bellows mechanism case A is brought into close contact with the resin receiving plate B. Under this condition, the screw D is inserted into the space 12 of the front plate 1 to put the above-mentioned both-matching plates 11 and 21 on the boss b. Although it may be screwed (see FIG. 5), as shown in FIG. 6, it is possible to use the front plate 1 in close contact with the resin receiving plate B. 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 above-mentioned 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 a screw is provided at one end (on the mounting side of the rear plate 2 in the figure) of one of the through holes 13 and 23. The fixing plate 24 is provided. That is, the belling mechanism case A is brought into close contact with the wooden receiving plate C (the screw fixing plate 24 is brought into close contact with the receiving plate C), and under this condition, the front plate 1 side is inserted into the through holes 13 and 23. Insert the screw E and screw the belling mechanism case A to the wooden support plate C (see FIG. 7).

As described above, the bell-swing mechanism case A of the present invention can be easily attached to the resin receiving plate B and the wooden receiving plate C.

In the illustrated embodiment, the space portions 12 and 22 (in other words, the laminated plates 11 and 21) and the through holes 13 and 23 are provided in the upper part of the bell-swing mechanism case, respectively. In this consideration, the place and the number of places are arbitrary.

[0018]

[Effect of the device]

 As described above, the bellows mechanism case of the present invention can be easily attached to both the resin-made receiving plate and the wooden receiving plate, and can be shared by both receiving plates. It is possible to provide general versatility, and the production plan and inventory management of parts can be labor-saving.
