Description

[Detailed explanation of the idea] The present invention relates to a watch.

Conventionally, a watch mechanism case has been fixedly attached to the rear surface of a dial holder at multiple locations using screws.

However, using screws as the means for attaching the watch mechanical case not only increases the number of parts, but also takes time and effort to manufacture and assemble.

Taking this point into consideration, the present invention aims to provide a watch that has a small number of parts and is easy to manufacture and assemble.

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

In FIGS. 1 and 2, a dial plate holder 2 that also serves as a dial plate is provided on the front side of a watch frame 1.

A watch mechanism case 3 is disposed on the back side of the dial holder 2, and the watch mechanism case 3 consists of a lower case 4 and an upper case 5.

The lower case 4 is divided by a partition wall 6 into a watch mechanism storage section 4a and a battery case 4b.

The storage section 4a is connected to an upper case 5 that seals the storage section 4a.

In addition, according to the illustrated example as this coupling means, the storage section 4a
Engagement pieces 7a, 7b, and 7C, which are engagement portions, project laterally from both side edges of the opening end.

Pressing parts 8a, 8b, and 8C, which are locking parts, are formed downward from the top surface on both side walls of the opening end of the upper case 5, and the pressing parts 8a, 8b press a part of the battery case 4b. is occupying.

Inside the lower ends of the pressing parts 8a, 8b, 8C, each engaging piece 7a
, 7 b and 7 C are removably engaged.

For this reason, the upper case 5 is coupled to the lower case 4.

Of course, both the upper and lower cases 4 and 5 may be connected by screws.

Now, the means for attaching the watch body case 3 to the dial holder 2 will be explained.

On the outer surface of the elastic side wall 9 of the battery case 4b, engaging pieces 10a and 10b, which are engaging parts, project laterally.

Each engagement piece 10a. 10 b is removably engaged with locking claws 12 a and 12 b that are locking portions of support plates 11 a and 11 b that are erected on the sides from the back surface of the dial holder 2. There is.

Similarly, a side plate 13 is also placed on the side (left side) of the storage section 4a.
is provided upright, and the retaining piece 10C of this side plate engages with a locking claw 12C of a support plate 11C that stands up from the dial holder 2.

Therefore, the lower case 4 is attached to the dial holder 2 by the support plates 11a to 11C.

Engagement pieces 10 a , 10 b and 10 C that correspond to each other and locking claws 12 a , 12 b and 12
In order to fix the engagement with C and strengthen the attachment of the lower case 4, the following fixing means is provided.

That is, on one side (right side) of the lower case 4, the battery 14 in the battery case 4b presses the inner surface of the elastic side wall 9 with its outer peripheral surface.

Due to the pressing force, the engaging pieces 10 a and 10 b on one side
The engagement between the engagement claws 12 a and 12 b is fixed.

For this reason, the material of the side wall 9 is preferably flexible, and the supporting plates 11a and 11b, which are locking members, are preferably rigid.

Note that the pressing portion s of the upper case 5 also applies to the other nine circumferential surfaces of the battery 14.
a, sb are pressed laterally (leftward), and the engagement with the engagement pieces 7a, 7b of the lower case 4 is fixed, thereby reinforcing the connection between the upper and lower cases.

On the other side of the lower case 4, a fixing pin 15, which is a projection rising from the inner surface of the watch frame body 1, is press-fitted between the side plate 13 and the pressing portion 8C of the upper case 5.

Due to the pressing force of the fixing pin 15, the engaging piece 10C is fixedly engaged with the locking claw 12C of the support plate 11C, and at the same time, the engaging piece 7C of the lower case 4 is also engaged with the pressing part 8C of the upper case 5. Strongly connected.

In this way, both sides of the lower case 4 are connected to the battery 14 and the fixing pin 1.
Although it can be attached to the dial holder 2 without using screws with a pressing force of 5, screws may be used for the fixing pins.

That is, as shown in FIG. 3, the engaging piece 10d provided on the side wall 9 of the battery case 4b engages with the locking claw 12d of the support plate 11d protruding from the inner surface of the watch frame body 1, and this The mating state is fixed by the pressing force of the outer peripheral surface of the battery 14.

A holding plate 1 is provided on the side (left side) of the lower case 4.
6 is fixed to a support column 17 that stands up from the inner surface of the watch frame body 1 with a screw 18.

19 is a front glass, 20 is a pointer, and 21 is a battery removal lid.

As explained above, according to the present invention, it is possible to suppress the screwing of the watch mechanical case to the mounting plate as much as possible.
The number of parts is reduced, making manufacturing and assembly easier. Furthermore, by inserting the battery into the battery case, the deformation of the elastic side wall is restricted and the retention with the locking member is strengthened. have an effect.
