Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a watch.

(Prior Art) Traditionally, watches have a clock mechanical body mounted in a hollow space between a front frame and a rear frame, and the front and rear frames are connected and fixed using screws or other connecting means. The structure is well known.

(Problem that the invention aims to solve) However, in a watch with such a configuration, apart from the structure of the watch mechanism itself, other structures are inevitably complicated, and therefore technical improvements are needed to reduce manufacturing costs. However, there were certain limits to improvements in the complexity of assembly work.

Therefore, the purpose of this invention is to make it extremely easy to manufacture.
The aim is to provide a watch that is easy to assemble.

(Means for Solving the Problems) The features of the present invention are that an engaging groove 11 is formed on the inner side of the lower side of the watch case 1 with a front opening, and that the end face of the side edge of the watch case is inclined rearward. Latching groove 1
2 and 12, and an engagement protrusion 21 that engages with an engagement groove of the watch case is formed at the lower end of the mounting plate 2 of the watch mechanical body that fits into the opening of the watch case,
Furthermore, hooking portions 22, 22, which are hooked into the hooking grooves, are formed on the side edges of this mounting plate.

(Function) To assemble the watch, first attach the watch mechanical body 6 and the hands 4 and 5 to the mounting plate 2, and then insert the engagement protrusion 21 on the mounting plate into the engagement groove 11 on the lower side of the watch case 1.
At the same time, while swinging the mounting plate 2 around this engagement protrusion to engage the latch portion 22 in the latch groove 11 of the watch case 1, the engagement protrusion 2 of the mounting plate
1 into the engagement groove 11 of the watch case, thereby attaching the mounting plate 2 to the watch case 1 and completing the assembly of the watch.

(Example) Next, an example of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 3, a watch case 1 made of synthetic resin and having a triangular cross section and an opening on the front side has an engaging groove 11 on the inside of the lower side, and on both side edges of the case. As shown in FIGS. 1 and 2, locking grooves 12, 12, which are inclined toward the rear, are formed in the end faces located slightly above the center portion, respectively. The mounting plate 2, which is fitted and attached to the opening edge of the watch case 1, is made of transparent synthetic resin, and has an engaging protrusion 21 formed at its lower end, and the length of this protrusion is as follows. The length of the protrusion is approximately half the width of the mounting plate (FIG. 2), and the protrusion can be engaged with the engagement groove 11 of the watch case. Also, mounting plate 2
At both side edges, there are formed hooking pieces 22, 22, which are hooking portions that are hooked into the hooking grooves 12, 12.
A dial plate 3 and hands 4, 5 are provided on the front surface of the mounting plate 2, and a timepiece mechanical body 6 is mounted on the back surface of the mounting plate. Also, the clock mechanical body 6
A pendulum 7 is suspended from the clock mechanism, and the swinging ball 8 of the pendulum makes a reciprocating swing motion, and the hands 4 and 5 are driven to display the time.
A reflecting plate 9 is attached to the inner wall of the rear half of the watch case 1. The reflecting plate 9 is made of an elastic synthetic resin plate whose surface is mirror-treated and bent into a V-shape. Therefore, the reflecting plate 9 reflects the swinging ball 8, and the reflected state of the swinging ball can be seen through from the front of the watch case 1. Note that both end surfaces of the reflection plate 9 are in contact with the back surface of the mounting plate 2.

To assemble the watch, first attach the watch mechanical body 6 and hands 4, 5 to the mounting plate 2, and then align the engagement protrusions 21 of the attachment plate 2 with the engagement grooves 11 on the lower side of the watch case 1 ( 1), the mounting plate is swung around the engagement protrusion, and the latching pieces 22 are inserted into the latching groove 1 of the watch case.
2 and 12, the engagement protrusion 21 of this mounting plate is dropped into the engagement groove 11 of the watch case (the state shown in FIG. 2).

(Effects of the invention) Since the present invention has the above-mentioned configuration, the other configurations except for the watch mechanical body are extremely simple, and it is extremely effective in improving manufacturing costs and assembly workability.

Claims (1)

[Scope of Claim for Utility Model Registration] An engaging groove is formed on the inner side of the lower side of the watch case with a front opening, and a locking groove that slopes backward is formed on the end face of the side edge of the watch case. The lower end of the mounting plate of the watch mechanical body that fits into the opening of the watch case is formed with an engaging protrusion that engages with the engaging groove of the watch case, and the side edge of this mounting plate is further formed with the above-mentioned latch. A watch with a hook that hangs in a groove.
