Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting structure for an outer frame of a timepiece.

[Prior Art] Conventionally, as a mounting structure for an exterior frame of a timepiece, for example, in an alarm clock, a mounting boss formed on a front surface of a rear frame and a mounting boss projecting on a front surface of a rear frame are provided with screws from the rear of the rear frame. It is known that it is fixed through. Further, in the alarm clock of the prior art, a mounting plate having a timepiece mechanical body mounted on the back is fixed to a mounting boss formed on the inner surface of the rear frame via a first screw, and a front surface is provided with a recess for mounting a dial. The front frame provided is made to engage both outer peripheral portions of the front frame and the rear frame with each other, and is fixed to the front surface of the mounting plate through a second screw, and the second screw is covered so that the dial plate is recessed on both sides. It is known that the tape is attached, a front cover is provided in front of the dial, and the front cover is fixed to the front frame.

[Problems to be Solved] However, in the above-mentioned first conventional technique, there is a problem that the design of the outer frame is damaged because the screw is visible from the outside.
In the second prior art, when the first and second screws cannot be seen from the outside, dust is clogged in the teeth of the train wheel in the machine body and the clock stops or is delayed. Cannot be easily disassembled during repair. That is, the structure is difficult to understand from the appearance, the front frame and the rear frame are mistaken for only the elastic coupling means of the outer peripheral part, and the frame is damaged by trying to forcibly remove it with a tool such as a screwdriver, or the front cover is There was a problem that the dial that was removed was bent.

Therefore, an object of the present invention is to provide a mounting structure for an outer frame that not only allows the screws to be invisible from the outside but also can be easily disassembled and repaired by a simple watch repair technique.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the feature of the mounting structure of the exterior frame of the timepiece of the present invention is that the mounting plate has a dial on the front surface and a timepiece mechanical body on the back surface. In, the battery storage chamber is integrally formed, the mounting plate is fixed to the rear frame and is housed inside the front frame having the front cover and the rear frame,
The front frame and the rear frame are coupled by elastic coupling means formed on the outer edges of each other, and the support plate that constitutes one side of the battery storage chamber and the tongue piece that extends from the front frame to the rear frame are formed. It is fixed via a screw, and a battery cover is provided in the rear frame with a hole for inserting and removing a battery to be stored in the battery storage chamber and a screw so as not to be visible from the outside.

Is a pair of locking portions 1a, 1a protruding forward from the mounting plate 1.
Positioned and fixed by (1st and 6th illustrations).

In FIG. 1, a switch board 10 is electrically coupled to a circuit board 11 on which an electronic circuit (not shown) is formed, and the circuit board 11 is mounted on a mounting boss 1b ... It's stuck. A support plate 1c, which constitutes one side of a battery storage chamber 1e, which will be described later, extends and is formed at the lower part of the mounting plate 1 and the batteries 12, 12 (first 7) is vertically formed, and two insertion / removal holes 1d, 1d (7th illustration) are formed. Support pillars 13 are provided near the hole 1d.
A tip portion 13a thereof is provided so as to project through 1c. Tip 1
A plus battery contact piece 14 and a minus battery contact piece 15 are coaxially provided in 3a so as to be swingable in parallel with the opening surface of the hole 1d, and two pieces are provided in an electrically conductive state in a stacked manner. . A stopper seat 16 is attached to the tip portion 13a of the support column 13 so that both battery contact pieces 14 and 15 do not fall out. Holes 1 in both battery contacts 14 and 15
Vertical bending portion 14 that engages with the inner peripheral edge of d, 1d to regulate the swing angle
a and 15a are formed respectively.
