Description

[Detailed explanation of the idea] The present invention relates to a module support device for a watch.

Conventionally, the module has been pushed up by the back cover through the middle frame and fixed to the body of the watch case, and waterproofness between the body and the back cover has been achieved by interposing a gasket. The buttons that give various instructions to the module are attached to the side holes of the body and perform their functions.

However, in recent years, watches have become cheaper, and the conventional watch case structure is no longer able to achieve the lower prices.

The present invention solves the above-mentioned problems, facilitates the assembly of the module into the watch case, holds the module in a balanced manner, improves the operability of the push buttons, and improves the connection between the module and the case back. The purpose is to make the watch case thinner by making effective use of space.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. FIGS. 1A, 1B, and 2 are cross-sectional views of a timepiece, showing an embodiment of the module support device of the present invention. In FIG. 2, 1 is a watch case, which includes a case 2, a glass 4 attached to an inward protrusion 2a on the upper part of the case 2 with a packing 3 interposed therebetween, and a back cover 5 attached to the lower part of the case 2. It is composed of

6 is a module stored in watch case 1;
7 and 8 are two recessed portions 6a on the sides of the module 6.
Fixed contacts and movable contacts of the switch provided in 9
10 is a battery that is partially housed in the recess 6b of the module 6, and 10 is a module support member that fixes the module 6 to the watch case 1.

FIG. 1A is a bottom view of the main body of the module support device, and FIG. 1B is a sectional view taken along line BB in FIG. 1A. It is composed of a push button 12. The main body 11 is integrally molded from an elastic material such as rubber or soft synthetic resin, and has two concave holes on the rectangular base plate 13 of the main body 11 at one side edge of the module 6 in the longitudinal direction. A short cylindrical module presser 14 is integrally formed at the outer periphery of the entry portion 6a and protrudes from the side surface of the back cover.

A U-shaped module presser 15 is integrally formed on the other edge of the substrate 13 and protrudes toward the back cover. A flexible portion 16 is connected to the inner periphery of each cylindrical module presser 14 .

Each flexible portion 16 has an outer peripheral portion inclined toward the module 6 side, a central portion protruding toward the module 6 side, and a through hole 17 formed therein. The outer peripheral part of the substrate 13 is inclined in the direction in which the module pressers 14 and 15 protrude, and is formed horizontally following this inclined part,
Packing 18 is integrally formed around the periphery of the horizontal portion. Positioning protrusions 19 are integrally provided at appropriate locations on the substrate 13 (in the illustrated example, two locations adjacent to the outside of each cylindrical module holder 14) on the opposite side of the module holders 14 and 15, that is, in the module direction. The center part of the board 13 is the module presser 1
The recessed part 6 of the module 6 is projected toward the 4 and 15 sides.
A recess 20 for housing the battery 9 is formed in the side surface of the module. The push button 12 is molded from hard synthetic resin or metal, and a flange 22 is integrally formed on the outer peripheral edge of a main body 21, and the main body 21 is integrally provided with a protrusion 23 that protrudes in the direction of the module 6.

This push button 12 has a protruding portion 23 that is connected to the base plate 13.
The inner end of the push button 12 is in direct contact with the movable contact 8.
The push button 12 may be fixed to the through hole 17 by adhesive, or may be insert-molded and fixed when the substrate 13 is molded.

To explain the assembly procedure of the module support member 10 of the present invention, first insert the module 6 into the watch case 1, place the watch case 1 so that the recessed part 6b of the module 6 is at the top, and then insert the module 6 into the watch case 1.
Insert the battery 9 into the module support member 10, and then insert the positioning protrusion 19 of the module support member 10, on which the push button 12 has been attached in a watertight manner, into the positioning hole 6c of the module 6, and also insert a part of the packing 18 of the module support member 10 into the positioning hole 6c of the module support member 10. into the groove 2b in the body 2 of the watch case 1.

After that, fit the push button 12 into the hole 5a of the back cover 5,
Its peripheral edge is attached to the lower end peripheral edge of the body 2. As a result, the module pressers 14 and 15 are compressed between the module 6 and the back cover 5, and the upper periphery of the module 6 is pressed against the protrusion 2a of the body 2, and the module 6 is fixed so as to be able to be buffered, and the battery 9 is pressed against the module 6. I will support you. Therefore, the cylindrical module presser 14 serves both as a support for the push button 12 and as waterproof and dustproof packing for the inside of the watch case 1 from the hole 5a.

On the other hand, the packing 18 interposed between the case 2 and the back cover 5 can make the inside of the watch case 1 waterproof and dustproof from the periphery.

As described above, the present invention fixes the module in a watch case so as to be able to relax by pushing up the module holder protruding from the side surface of the back cover of the module support member with the back cover, and at least one of the module holders is fixed in a cylindrical manner. Since the push button is watertightly attached to the inner periphery of the push button via the flexible part, only the flexible part deforms when the push button is pressed, improving the resilience of the push button.
Since the push button is made of a hard material different from that of the module support member, the pressing feeling of the push button is the same as that of the conventional one, and the conventional operability can be maintained.

In addition, the module support member is equipped with packing to make the watch case waterproof, a push button made of synthetic resin or metal for external operation, and a recessed part to store and hold the battery, making it easy to attach the module to the watch case. In addition, since the module support member is pressed into contact with the module without any gaps, it is possible to make the watch case thinner. Further, since the push button is mounted in a watertight manner in a through hole formed in the center of the flexible part of the module presser, the push button is securely mounted and will not easily come off.
