Description

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

Conventionally, the movement was placed on the back of the mounting plate, and the time display, front cover, and glass edge were placed on the front, and the watch was assembled into an integral part, which was then attached to the frame to assemble the watch. be. In this case, a plurality of pillars are provided protruding from the back of the mounting plate, and mounting brackets with spring properties are screwed to the pillars, the outer circumferential back of the mounting plate is brought into contact with the front of the frame, and the tips of the mounting brackets are attached to the frame. The frame is clamped by locking onto a stepped portion provided on the inner peripheral surface of the mounting hole and tightening the screw. Furthermore, a plurality of other pillars are provided protruding from the back of the mounting plate, and the rear frame is screwed to these pillars. With this structure, it is possible to withstand changes in the dimensions of the wood due to changes in humidity, such as when the frame is made of wood.
Although it has the advantage of being able to cope with the spring properties of the mounting brackets, it is structurally complex due to the provision of multiple pillars, and the number of parts such as multiple mounting brackets and screw fastening work is large, making assembly work complicated. There was a drawback.

According to the present invention, the clock part can be attached to the frame by simply screwing the rear frame, and by pressing the mounting piece protruding from the back of the mounting plate of the clock part against the frame with the rear frame itself. To provide a clock which has a small number of parts, can cope with dimensional changes such as a wooden frame, has a simple structure, and is easy to assemble.

An embodiment of the present invention will be described with reference to the drawings.
First, the configuration of the clock section 1 is as follows. The movement 3 is fixed to the back of the mounting plate 2.
A dial plate 4 is fixed to the front. A pointer 6 is attached to a pointer shaft 5 protruding from the front of the dial, and constitutes a time display section. A front cover 7 covering the time display portion is supported at the front end of the facing 2a of the mounting plate 2, and is prevented from falling off by a glass edge 8. The glass edge 8 is attached to the mounting plate 2 by a locking claw 8a.
It is locked in. A plurality of mounting pieces 9 and a shorter mounting post 10 are protruded from the back surface of the mounting plate 2. The mounting piece 9 has an outwardly inclined inclined surface 9a protruding from its tip.

A mounting hole 12 for the timepiece portion 1 is bored in the frame 11, and a pressure contact portion 13 against which the mounting piece 9 is pressed is formed on the inner peripheral surface of the mounting hole. Further, the peripheral portion of the mounting hole 12 on the front surface of the frame 11 serves as a mounting surface 14 against which the back surface of the glass edge 8 comes into contact.

The rear frame 15 is in the shape of a bowl and is located inside the mounting hole 12, and the center portion 15a is shaped so that it can enter inside the mounting piece 9 and can come into contact with the rear end surface of the mounting post 10. , the peripheral wall portion 15b is expanded toward the rear, and the outer peripheral portion 15c is connected to the mounting hole 1.
It has a shape that can be inserted into the rear opening of No. 2. A pressing rib 16 is provided on the surface of the peripheral wall portion 15b facing the mounting piece 9. The rear frame 15 is attached by screwing screws 17 into the mounting post 10, and at this time, the mounting piece 9 is pushed open by the peripheral wall portion 15b and the pressing rib 16 and pressed against the pressure contact portion 13.

To assemble the timepiece of the present invention, the timepiece section 1 is first assembled, and then inserted from the front into the mounting hole 12 of the frame 11 so that the back surface of the glass edge 8 is brought into contact with the mounting surface 14 of the frame 11. Next, the rear frame 15 is inserted from the back of the mounting hole 12 and screwed to the column 10 with the screws 17. As the screws are tightened, the rear frame 15 moves forward as shown by arrow A in FIG. Pressure contact portion 13 is pushed outward as shown by arrow B.
being pushed to. By pressing the inclined surface 9a of the mounting piece 9 against the pressure contact portion 13 with sufficient force,
The clock part 1 is firmly connected to the frame 11 and cannot escape any longer.

In the embodiment shown in FIG.
Although the tip of 9 does not have a protruding slope,
By making the pressure contact portion 23 of the frame 21 a corner portion, when the mounting piece 29 is pushed apart by the peripheral wall portion 25b and the rib 26 of the rear frame 25, it is strongly pressed against the pressure contact portion 23 of the mounting hole 22, and as shown in the above example. In exactly the same way, sufficient force can be obtained to connect the watch part to the frame 21.

As described above, according to the present invention, the clock part can be connected to the frame by simply bending the mounting piece protruding from the mounting plate of the clock part with the rear frame and pressing it against the frame, which reduces the number of parts. It has a simple structure and is easy to assemble, can sufficiently cope with changes in dimensions due to humidity, such as with a wooden frame, provides a strong connection, and has the effect of reducing costs.
