Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urethane band for a wristwatch, and more particularly, to an improvement in a concave / convex portion on a timepiece mounting side of the urethane band.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Publication No. 63-68809 discloses this type of urethane band. This publication describes that a decorative member in which a thick ridge and a thin valley are integrally connected is fitted on the timepiece mounting side of the urethane band.

[0003]

However, in the above publication, since the decorative member mounting portion of the urethane band is flat, a stepped portion must be provided on both sides in the longitudinal direction and the decorative member to be inserted must be pinched and stopped. Therefore, there is a problem that it is not easy to insert the decorative member. There is also a problem that the decoration member cannot be color-coded because the decoration member is integrated.

[0004]

According to the present invention, several grooves are provided around the timepiece mounting side of the urethane band, and a ring is fitted into each of the grooves so that the outer half protrudes. It is to solve the problem.

[0005]

A plurality of rings of the same color or of different colors are fitted into the urethane band, and are sequentially guided and fitted into the grooves provided in the urethane band. The inner half of the ring fits into the groove so that the ring does not slide out of place.

[0006]

An embodiment will be described below with reference to the drawings.

FIG. 1 shows a first embodiment, in which three concave grooves 2a, 2b, 2c, 2d, 2e are alternately formed on the front and back surfaces of the urethane band 1 which forms a color such as yellow on the timepiece mounting side. Form a bend.

On the other hand, a somewhat small-diameter ring 3 is separately formed from a stretchable wire having a circular cross section, and the ring 3 is inserted into the urethane band 1 to be inserted between the front and back concave grooves 2a and 2b, and between the concave grooves 2c and 2d.
It is sequentially fitted between the space and between 2e and the step surface 2f. The three rings 3 fitted are aligned in the same color or
It is up to you to add the seed colors.

FIG. 3 shows an example in which three rings 3 are connected by connecting members 4a and 4b provided on both sides, and FIG. 4 shows an example in which three rings 3 are connected by a connecting member 4c in the middle of the back surface.
In this case, a fitting groove 4d is provided on the back surface of the urethane band 1 so that the connecting member 4c is fitted.

FIG. 5 shows another embodiment in which a flange 5 is provided around the timepiece mounting side of the urethane band 1 and a flat portion 6 is formed, and the flat portion 6 is formed in a different color from the urethane band 1. An example in which the wide-angle ring 7 is fitted is shown.

[0011]

[Effect of the Invention] As described above, in the present invention, several grooves are bent alternately on the front and back surfaces of the urethane band on the timepiece mounting side, and straddle the alternate front and back grooves. Since several rings having elasticity are fitted, the rings are easily fitted and have an effect that they do not come off easily. In addition, there is an effect that colors can be assigned between the rings.
