Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a mechanical body used in a watch or the like.

Conventionally, for example, a watch mechanical body is composed of a mechanical body and a watch case that houses the mechanical body.

Some of these watch mechanical bodies are attached to the back of the front frame of the watch at multiple locations with screws.

However, since all screws are used in this way, there is a drawback that the number of parts increases accordingly, and manufacturing and assembly operations are also time-consuming.

The purpose of this invention is to securely hold the machine body at the same time as connecting the front frame and the rear frame, and to reduce the number of parts required for this purpose and to facilitate assembly with a single screw. .

The present invention is characterized by a cylindrical holder that protrudes from the inner surface of the rear frame toward the front frame, and has a screwdriver insertion hole and a bottom surface with a hole. , a support column facing the bottom surface of the holder, a screw inserted through the hole and screwed into the support column to connect the support column and the holder, and a screw that is screwed into the support column and the support column. The present invention includes a mechanical case which is pressed and clamped by the lower end of the holder at the same time as it is coupled to the holder wheel projecting from the frame.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a front frame, and 2 is a rear frame, and these frames form, for example, the frame of a watch.

The front side of the front frame 1 serves as a dial holder 3 with a button, and a watch mechanical body 4 is attached to the back of this dial holder.

5 is a front cover, and 6 is a dial plate. As shown in FIG. 3, the watch mechanical body 4 includes a mechanical body (not shown).

), and an upper case 4a and a lower case 4b for sealing the main body.

Here, the mounting means for the timepiece mechanical body 4 will be explained based on FIGS. 1.3 and 4.

One location on one side (right side) of the lower case base 4c is screwed to a support column 8 that stands up from the back surface of the dial holder 3 using a screw 7.

At least one location on the other side of the lower case base portion 4c is
It is held at the tip of the holding body 9 of the rear frame 2.

That is, as shown in FIG. 4, the holder 9 is provided protruding from the inner surface of the rear frame 2 toward the front frame 1, and has an insertion hole for inserting a screwdriver and a bottom surface with a hole. It is an integrally formed cylindrical body with an H-shaped cross section, and its tip abuts against the base portion 4c of the lower case 4b.

A support column 10 standing up from the back of the dial holder 3 is inserted into the lower part of the holder 9, and a screw 11 is inserted from the other side through the hole in the bottom surface and screwed into the support column 10 from the upper end surface. This holder is fixed to this support column.

At the same time that the front frame 1 and the rear frame 2 are joined and fixed in this way, the lower end of the holder 9 presses the back surface of the lower case 4b, so that the lower case is connected to the holder and the dial holder 3. It is clamped and fixed between.

In addition, in order to reinforce the attachment of the other side of the lower case 4b, an elastically deformable locking pawl 12 is provided protruding from the back surface of the dial holder 3, as shown in FIGS. This locks the lower case base portion 4c.

As shown in FIGS. 1 and 3, the lower cane stand 4c has a plurality of (
In the drawing, there are three (3) positioning holes 13.・・・・・・・・・
・is provided.

Each hole 13. A protrusion 14 protruding from the front frame 1 is inserted into the lower case 4b to position the lower case 4b.

Alternatively, a positioning hole may be provided in the front frame 1 and a projection may be provided in the lower case 4b.

In FIGS. 1 and 2, reference numeral 15 denotes a buzzer horn, which is detachably attached to pillars 16, 16 that stand up from the dial holder 3 via a collar 15a.

The upper end portion of the horn 15 is detachably held by a holding portion 17 provided on the inner surface of the rear frame 2.

To attach the watch mechanism body 4 to the front frame 1, one side of the base 4c of the lower case 4b is fixed by screwing the screw 7 into the support column 8, and then the rear frame 2 is joined to the front frame 1. Then, the support column 10 fits into the holder 9, and by screwing the screw 11 into this support column, the rear surface of the lower case is fixedly held by the tip of the holder.

The present invention is not limited to those relating to watch mechanical bodies.

Since the present invention has the above configuration, by combining the front frame and the rear frame and inserting screws through the screwdriver insertion hole, the front frame and the rear frame are fixed simultaneously and the machine case is fixed. Since it can also be fixed, assembly is easy, and the machine body can be accurately attached with a single screw.

Furthermore, since the screws are not visible from the outside, it is effective in maintaining the aesthetic appearance of the design.
