Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a plastic watch band.

<Problems to be solved by this invention> Conventionally, plastic watch bands have been simply molded into a band shape with unevenness on both sides, resulting in the problem of being monochromatic and monotonous. The present invention attempts to solve such problems.

<Structure of the invention> The present invention has a step-expanded tube part for attaching to a watch case at one end, and a plurality of thin pieces that can be cut and adjusted and a plurality of step-expanded semicircular shaft parts arranged in parallel at the other end. A core member made of urethane, a number of plastic pieces that are removably inserted in parallel to the core member, and one end of the pieces are brought into contact with each other at the stepped expanded shaft portion. stop it,
The piece at the other end is removably fitted onto the semicircular shaft, using a middle clasp having a split groove on one side and a step-widening semicircular hole following the split groove. This is a plastic watch band characterized by a contacting surface.

<Example> Examples will be described below based on the drawings.

One end is provided with a stepped enlarged cylindrical part 1 having a mounting hole 1a inside, and the other end is provided with a stepped enlarged semicircular shaft part 2 for inserting a middle clasp in several threads, and a shaft part 2 for cutting adjustment is provided between each shaft part 2. A urethane core member 4 provided with a thin piece portion 3 is integrally formed, and an insertion hole 5 is formed in this urethane core member 4.
The pieces 6 made of plastic of different colors and having a substantially rectangular shape in plan view are inserted alternately, and the piece 6 located at one end is fixed in contact with the side surface of the stepped expanded cylinder part 1, and the other pieces are The piece 6 at the end is fixed in contact with one half of the middle clasp 7a or 7b fitted to the semicircular shaft 2 to form watch bands 9a, 9b. In addition, 8 is a mounting groove for the middle clasp, which is formed by a semicircular groove of the same shape as the semicircular shaft part 2 following the split groove 8a, so that once it is fitted to the shaft part 2, it cannot be pulled out by elastic action. becomes.

The watch bands 9a, 9b are secured by a spring bar 12 by inserting the stepped enlarged tube portion 1 into the mounting box portions 11a, 11b of the watch case 10, which are formed into a P-shape in plan view.

The watch band formed in this manner can be flexibly stretched based on the urethane core member and can be comfortably worn around the wearer's wrist. Remove the middle clasps 7a and 7b fitted to one or both of them against the pressure, then pull out a part of the piece body 6, expose the thin piece part 3, and press either of the arrows AB in FIG. The length can be adjusted by cutting at a point.

At this time, the arrangement of the colored pieces 6 can also be changed. After adjusting the length, the bridge body 6 is refitted and the clasp is reinstalled for use.

<Effects of the invention> As described above, the present invention forms a plastic watch band using a urethane core member and a number of pieces that fit into the core member. It has the appearance of a band made up of pieces arranged in parallel, and since the piece bodies are made of plastic that can be easily colored, the effect is that a multi-colored band can be obtained, which is not possible with metal bands. In addition, the watch band of the present invention has a step-expanded tube portion formed at one end of the core member with a large number of pieces that fit into the urethane core member, and a middle clasp that fits onto the shaft at the other end of the core member. Since the band is fixed by contacting with the contact surface, it is possible to assemble the band extremely easily.

In addition, if the band length is longer than the wearer's wrist, remove the middle clasp from the urethane core member, release the contact stop on the bridge body, and remove it to expose the thin piece that can be cut and adjusted. This has the effect that the required thin piece can be cut and adjusted between the semi-circular shaft and fit around the wearer's wrist very easily.

In addition, since the watch band is made by inserting plastic pieces into the urethane core member in parallel, the watch band bends and stretches flexibly based on the urethane core member and fits comfortably around the wrist. Furthermore, it has the effect of repelling sweat and water and preventing deterioration and generation of bad odors due to penetration and retention.
