Description

[Detailed description of the invention] The present invention relates to an exterior body for a watch or the like.

The exterior body of a watch or the like generally has two frames, a front frame and a rear frame, which are screwed together, and a transparent front cover is press-fitted into the front frame. The dial is then fixed to the dial holder on the front frame. In addition, a dial holder is formed on the front frame,
There is also an exterior body in which a dial is inserted, a transparent cover is press-fitted, and the rear frame is screwed to the front frame. These have a large number of parts, require time and effort to assemble, and are expensive.

The present invention eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In Figures 1 to 3, reference numeral 1 denotes the exterior body of the watch, which is an integrally molded product in which each member constituting the exterior body is integrally formed of transparent resin such as transparent polypropylene. As shown in the figure,
In the unfolded state, the dial part 2, the front frame 3, and the rear frame 4 are connected to each other via bendable thin parts 5 and 6, respectively, around the front frame 3. The dial portion 2 has a pointer shaft protruding from the center thereof and a center hole 2a into which the timepiece mechanical body 7 is attached. Dial part 2
A dial leg 2b protrudes from below, and a mounting hole 8a forming a fixing means 8 for assembling and fixing the exterior body 1 is bored in this leg. The front frame 3 is made up of an outer peripheral edge 3a, a front face 3b, and a front frame leg 3c facing the dial leg 2b via a joint 5.
The center is hollow and serves as a space for the pointer. The dial portion 2 can be seen through from the front of the front frame. A boss portion 8b constituting the fixing means 8 is provided on the front frame leg portion 3c.
This boss portion is located symmetrically to the attachment hole 8a with respect to the coupling portion 5, and a screw hole 8c is bored therein. The rear frame 4 is composed of a side wall portion 4a, a rear surface portion 4b, and a base portion 4c, and is recessed in the center to provide a space for storing a watch mechanism body. The front part of the base part 4c is a recess 4d, into which the dial leg part 2b and the front frame leg part 3c can be fitted. A through hole 8d constituting the fixing means 8 is bored in the base portion 4c, and this through hole is connected to the connecting portion 6 by a screw hole 8d.
It is located symmetrically to c. A paragraph 4e is formed at the inner peripheral corner of the side wall portion 4a of the rear frame 4, and the dial portion 2 can be fitted into this paragraph. The dial part 2 is housed in a front frame 3 and a rear frame 4. Rear part 4b
A through hole such as a needle turning knob is perforated in the holder.

Next, the assembly of this exterior body 1 will be explained.
First, as shown in the second diagram, the watch mechanical body 7 is attached to the dial part 2.
Install. That is, in this example, the center fixing screw protruding from the watch mechanical body is fitted into the center hole 2a,
It is fixed with a locking nut. Then, attach the pointer 9 to the pointer shaft. A dial part 2 to which a watch mechanical body 7 and hands 9 are attached is rotated 180 degrees by a bendable thin part 5 and brought into contact with a front frame 3. As a result, the pointer 9 is located in the pointer space of the front frame 3, and the boss portion 8b is located within the attachment hole 8a. Next, with the dial part 2 facing the front frame 3, the front frame 3 is rotated 180 degrees by the bendable thin wall part 6, and the front frame 3 is brought into contact with the rear frame 4. As a result, the timepiece mechanism body 7 is stored in the timepiece mechanism body storage space. Further, the dial part 2 is fitted into the paragraph 4e of the rear frame 4, and the dial leg part 2b
fits into the recess 4d. The through hole 8d and the screw hole 8c face each other, and the set screw 10 constituting the fixing means 8 is screwed into the screw hole 8c through the through hole 8d and fixed.

In this way, the exterior body 1 includes the dial part 2, the front frame 3,
Since the rear frame 4 is joined and integrated by the thin parts 5 and 6, the structure is simple and manufacturing is easy, and the exterior body 1 can be assembled by simply bending the joint parts 5 and 6. The assembly can be easily performed by simply fixing with the fixing means 8.

Since the exterior body 1 is made of transparent synthetic resin, the rear frame 4 and the like may be made opaque by painting, etc., if necessary.

Further, characters may be directly formed on the dial plate portion 2, or characters may be fixedly attached thereto, or a dial plate on which characters are printed may be attached.

Next, other embodiments of the present invention will be described with reference to FIGS. 4 to 6.

Reference numeral 11 denotes the exterior body of the watch, which is an integrally molded product made of opaque resin such as polypropylene and integrally formed with each member constituting the exterior body, as shown in FIGS. 4 and 5. , dial part 1
2. In the unfolded state, the front frame 13 and the rear frame 14 are connected to each other via bendable thin parts 15 and 16, respectively, centering on the front frame 13. Dial part 1
2 has letters integrally formed on the front side, and a mounting boss 12 for attaching the watch mechanism body 17 on the rear side.
A is provided protrudingly, and a hook 18a constituting the fixing means 18 is provided below. A pointer 19 is attached to the pointer shaft of the timepiece mechanical body 17. The front frame 13 consists of an outer peripheral edge portion, and a central portion is depressed to provide a space for a pointer and an opening 13a. A front cover 20 made of a transparent member is attached to this opening. This front cover is attached by an appropriate method such as gluing or press-fitting, or it may be attached by integrally molding a front cover made of transparent synthetic resin by two-color molding.

The rear frame 14 includes a side wall portion 14a, a rear surface portion 14b, and a base portion 14c, and is recessed in the center to serve as a space for storing a watch mechanism. A paragraph 14d is formed on the inner periphery of the front end of the side wall portion 14a, and the dial portion 12 can be fitted into this paragraph. The rear portion 14b has an opening 14e for storing batteries or for adjusting the pointer.
is provided, and a small lid 21 is attached. Further, a hook hole 18b constituting a fixing means 18 with which a hook claw 18a can be engaged is provided below the side wall portion 14a. 14 is a notch into which the coupling portion 15 is fitted. The dial portion 12 is housed in a front frame 13 and a rear frame 14.

Next, assembly of the exterior body 11 will be explained.

First, attach the watch mechanical body 17 to the dial part 12,
Attach the pointer 19 to the pointer shaft. And dial part 1
2 is rotated 180 degrees by the bendable thin wall portion 15 and brought into contact with the front frame 13. As a result, guideline 19
is located within the pointer space of the front frame. Next, with the dial part 12 and the front frame 13 facing each other, the front frame 13 is rotated 180 degrees by the bendable thin part 16 and brought into contact with the rear frame 14. As a result, the watch mechanism body 17 is stored in the watch mechanism body storage space of the rear frame.
The dial part 12 is fitted into the paragraph 14d, and
The hooking claw 18a engages with the hooking hole 18b, and the exterior body 1
1 is assembled and fixed. And exterior vs. 11
Since everything except the front cover is made of opaque synthetic resin, there is no need to hide the inside of the exterior body by painting or the like.

As described above, according to the present invention, the dial part,
Since the front frame and the rear frame are connected to each other through bendable thin parts with the front frame in the center in the unfolded state, the configuration is extremely simple, and manufacturing is easy, and assembly is also extremely easy. .
