Description

[Detailed explanation of the idea] [Technical field of invention] This invention relates to watch bands.

[Background of the idea]

In general, wristwatch bands are mainly classified into metal bands and plastic bands, each of which has advantages and disadvantages. In other words, metal bands have a luxurious design, but lack elasticity, are heavy, and are expensive.Plastic bands have elasticity, are easy to wear, are lightweight, and are inexpensive, but have a poor design. Inferior to metal bands.

For this reason, conventionally it has been considered to apply surface treatments such as plating, printing, and hot stamping (transfer) to the surface of a soft plastic band to give it a high-class feel. When surface treatments such as plating, plating, and printing are applied, there is a problem in that the surface coating caused by the surface treatment easily peels off.

[Purpose of invention]

This idea was developed against the background of the above-mentioned circumstances; it is elastic, lightweight, inexpensive, has a high-class design, and has a surface coating that does not peel off due to surface treatments such as plating or printing. To provide a watch band that is not easily damaged and can be firmly bonded.

[Key points of the idea]

In order to achieve the above-mentioned purpose, this invention consists of a sheet-like base material made of elastic synthetic resin, and on the surface of the base material, a number of bridge members made of a synthetic resin harder than the base material are spaced apart from each other. The bridge members are made of hard synthetic resin and the surfaces thereof are subjected to surface treatments such as plating and printing in order to improve the appearance.

〔Example〕

Hereinafter, one embodiment of this invention will be explained along the molding procedure with reference to FIGS. 1 to 3.

FIGS. 1A and 1B show the primary molded member. This primary molded member (corresponding to the second synthetic resin member mentioned above) 1 is made of ABS resin, vinyl chloride resin,
It is made of hard synthetic resin such as AS resin using a primary mold, and consists of a large number of pieces 2... and this piece 2.
It is composed of a connecting portion 3 that connects...
In this case, among the many pieces 2..., the pieces 2 on the end side (left side in the figure) that are attached to the watch case (not shown) are formed to gradually increase in size, and the pieces 2 on the leftmost side are 2 is partially thick and has an attachment hole 2a for attachment to a watch case.

FIGS. 2A and 2B show a state in which a secondary molded member 4 is joined to the primary molded member 1. FIG. This secondary molded member (corresponding to the first synthetic resin member described above) 4 serves as the base material of the band,
It is made of elastic synthetic resin such as polyurethane resin, and is molded integrally with the primary molding member 1 using a secondary molding mold. That is, when molding the secondary molded member 4, before the primary molded member 1 molded in the primary molding die is cooled and solidified, the primary molded member 1 is placed in the secondary molding die. In this state, elastic synthetic resin is injected into the mold for secondary molding.
Cool and solidify. Then, the primary molded member 1 is welded to the surface of the secondary molded member 4, and these are integrally molded. Secondary molded member 4 molded in this way
is in the form of a sheet that is slightly wider than the pieces 2 of the primary molded member 1, and is bendable.

Figures 3A and 3B show the finished product. This finished product is produced by cutting off the connecting portions 3 of the primary molded member 1 integrally formed on the surface of the secondary molded member 4 as described above using a predetermined processing means such as a cutter, or 4 is bent and separated, and then a surface coating 5 is formed by subjecting the surface of the primary molded member 1 made of a hard synthetic resin to a surface treatment such as printing, plating, or hot stamping.

However, according to the watch band configured as described above, the surface of the secondary molded member 4 made of elastic synthetic resin such as polyurethane resin is coated with a primary molded material made of a synthetic resin harder than the above synthetic resin. Since the member 1 is integrally molded, it is lightweight and inexpensive. In addition, since the primary molded member 1 made of hard synthetic resin is formed as a large number of bridge members at intervals on the surface of the secondary molded member 4, the watch band can be easily formed by the spacing between the many bridge members. Can be bent. Further, if the surface of the primary molded member 1 made of a hard synthetic resin is subjected to surface treatment such as printing or plating to form a surface coating 5, a more excellent design and a high-class feel can be obtained. In this case, it is possible to obtain an even better design by molding the secondary molded member 4, which serves as the base material, from a transparent synthetic resin, or by making it the same color as the surface coating 5 to make it less noticeable. It becomes possible.

In addition, in the above watch band, 2
Hard piece member 2 placed at the end of the next molded member 4
A part of the watch case is made thick so as to protrude from the end, and a mounting hole 2a is formed for attaching the watch case to the watch case, so that the attachment to the watch case can be done extremely firmly without damaging the part. . Moreover, since the surface coating 5... is formed on the surface of the primary molded member 1 made of hard synthetic resin, the surface coating 5...
It is difficult to peel off and can be strongly bonded.

Furthermore, if the joint surface of the primary molded member is subjected to primer treatment and then the secondary molded member is welded, the adhesive strength can be further increased.

In the above-mentioned embodiment, a large number of pieces 2 of the primary molded member 1 were connected to the secondary molded member by connecting portions 3, but this invention is not limited to this, and each piece 2 may be formed one by one and joined to the secondary molded member.

Further, in the above embodiment, the hard second synthetic resin member was used as the primary molded member, but the present invention is not limited to this. It may also be formed by joining synthetic resin members.

[Effect of idea]

As explained above, according to the watch band of this invention, a large number of bridge members made of a synthetic resin harder than the base material are arranged at intervals on the surface of a sheet-like base material made of an elastic synthetic resin. Since the band is bonded with the same structure, it is possible to obtain a lightweight and inexpensive product, and the band can be easily bent. Moreover, since the numerous bridge members, which are the second synthetic resin members, are hard, it is possible to firmly adhere a surface coating formed by surface treatment such as plating or printing to their surfaces, which is excellent in terms of design. It has excellent advantages such as being able to obtain something with a high-class feel.
