Description

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

Conventionally, wall clocks have been proposed in which the front cover is removed in order to simplify manufacturing and assembly and reduce costs, but these types of clocks do not take protection of the hands or dust-proofing into consideration.

Furthermore, even if the watch has a front cover, as long as the outer periphery of the front cover is attached to the frame using special means as in the past, manufacturing and assembly will be labor-intensive and high-cost. Inevitable.

The purpose of the present invention is to provide a watch that is easy to manufacture and assemble, and is inexpensive, as well as having a protection for hands and dustproof effect.

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a front cover made of a highly elastic transparent plastic plate.

As shown in FIG. 3, the front cover 1 has a cover part 2 whose central part is bent forward and left and right sides are open.

A hooking portion 3 is provided which integrally extends rearward from the center of the upper edge 1a of the cover portion 2 and whose tip is bent downward at a right angle.

The latching portion 3 is provided with a latching hole 3a.

Although it is advantageous to provide the hooking portion 3 integrally with the front cover 1 in that the configuration is simplified, the present invention is not necessarily limited to this example.

On the left and right sides of the upper edge 1a of the cover part 2 are provided folded parts 4, 4 which are integrally folded back, and mounting grooves 4a, 4a are formed inside each folded part.

Similarly, the lower edge 1b is also formed with a folded part 5 which is folded back, and a mounting groove 5a is provided inside the folded part 5.

Folded parts 4, 4 of the upper edge 1a and folded part 5 of the lower edge 1b
is opposite to.

The folded parts 4 and 5 are mounted on the upper and lower edges of the dial body 6, which is disposed on the back surface of the front cover 1, through grooves 4a.

It is engaged and supported via 5a.

The folded portion 5 of the front cover 1 is positioned by a groove 6a provided on the lower surface of the dial body 6.

A watch mechanical body 7 is attached to the dial body 6 at the center of the back.

The mechanical body is fixed to the dial body by attaching a nut 9 to a shaft pipe 8 which protrudes from this and passes through the dial body 6.

Note that the method for attaching the watch mechanical body 7 to the dial body 6 is not limited to this example, and an appropriate method may be selected and used, such as directly fixing it to the back of the dial body.

A pointer 10 driven by the watch mechanism 7 is located within the cover part 2 of the front cover 1.

Note that the dial body 6 has a time display portion (not shown) formed by, for example, printing clock characters on the front surface thereof or pasting a film on which clock characters are printed.

The front cover 1 may have a structure in which only the part 2 of the cover facing the hand 10 (time display section) is made transparent, and the other parts are colored.

To assemble the watch constructed in this way, the watch mechanical body 7 and the hands 10 are assembled into the dial body 6 in advance, and this dial body is inserted from one side of the front cover 1 into the upper and lower folded parts 4.
, 5 are assembled as shown in FIG. 1 by slidingly inserting them along i4a+5a.

Another way of assembling is to attach the lower edge (or upper edge) of the dial body 6 to the lower folded part of the front cover 1 in the groove 5a.
(Alternatively, the upper folded parts 4, 4 can be removed using the grooves 4av 4a.
), then bend the front cover and engage the folded part 4.4 (or folded part 5) on the upper edge (or lower edge) with the upper edge (or lower edge) of the dial body 6. It may be something.

As described above, in the watch of the present invention, although the side surface of the front cover 1 is open, the pointer 10 can be protected from the front and the dustproof effect can be sufficiently achieved.

In addition, as another embodiment of the present invention, as shown in FIG. 4, if a cover part 12 is provided in a cap-like manner protruding from the center of the front cover 11, the upper edge 11a1 of the lower edge of the front cover Since no open portions are formed in the left and right edges 11d1 and 11d, the dustproof effect can be further enhanced.

In this case, the combination of the cover 11 and the dial body 6 is such that the cover is warped and the folded portions 4 and 5 are engaged with the dial body.

As described above, according to the present invention, the protection of the pointer and the dustproof effect can be obtained with a simple structure, and in addition, the folded part is provided integrally with the front cover and is manufactured so as to be engaged and supported by the dial body. Assembly is extremely easy, and costs can therefore be reduced.
