Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a watch band in which the pieces are connected by a hinge.

<Prior art> This type of watch band was first released in 1983.
There are No. 53065 and No. 59-29542. These publications describe that hinge portions are formed on both sides of the bridge body, and the bridge is connected by engaging the hinge portions and inserting a stop pin.

<Problems to be solved by the invention> However, when providing completed connecting hinges on both sides of the bridge body, there is a problem in that it is not possible to clearly differentiate the colors or polishing between the bridge bodies, and the connection There was a problem in that the hinge part loosened due to the frequent tensile pressure applied in the direction of opening the pieces, and the stop pin could be pulled out.

<Means for Solving the Problems> The present invention has protruding interlocking hinge bases arranged on both sides of the bridge body, and each of the interlocking hinge bases is provided with color coding and reinforcement against tension between the bridge body and the bridge body. A cylinder with an end, which also serves as a cylindrical body, is attached to fill the stepped portion between the bridge bodies, and the bridge bodies are connected by engaging the hinge base and driving the rivet body from the outside, This is an attempt to solve the above-mentioned problems.

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

FIG. 1 shows a first embodiment, in which a black substrate 11b is formed using Teflon resin and has a rectangular shape in plan view.
Hinge bases 12a, 12b and 13 are protruded from both sides of the board 12a, 12b and 13 are provided across the connection hole, and a top plate 11a of the same color is mounted on the board 11b to form a rectangular shape with a certain thickness in plan view. Black piece body 11
A hinge base is formed on both sides of the bridge body 11, and a white metal end cylinder (C ring) 14a, 14b is attached to each hinge base 12a, 12b,
Further, a gold-plated metal cylinder with ends 15 is attached to the hinge base 13 to form a double-structured hinge portion that fills the gap between the hinge base 13 and the bridge body. Each cylinder with ends sandwiches the base of the hinge base by widening the opening 16 between the end faces, and is tightly attached to each hinge base by the pressure of the opening 16 to return to its original shape. .

The pieces 11 are arranged in parallel with their hinge parts engaged and connected from the outside by driving a stud body 17 having a stepped enlarged head 17a to form a watch band. Furthermore, the stud body 17
By making the connecting hole in the hinge part a threaded hole, it can be replaced by inserting a removable screw. Further, the inner surface of the stepped enlarged head 17a of the stud body 17 and the screw comes into contact with the outer end surfaces of the end cylinders 14a and 14b, thereby preventing the end cylinders 14a and 14b from falling off. FIG. 2 shows a second embodiment, in which hinge bases 19, 20a, and 2
0b is formed, and a front plate 18a is mounted on a substrate 18b to constitute a piece body 18 having a predetermined thickness. This piece 18 constitutes a watch band finished in different colors in the same manner as in the previous example by attaching an end cylinder to each hinge base in the same manner as in the previous example.

<Effects of the invention> As described above, the present invention forms stepped interlocking hinge bases protruding from both sides of the bridge body, and covers each hinge base with an end cylinder that fills the stepped portions. Since each hinge part maintains the same plane with the bridge body and has a double structure, even if tensile pressure is frequently applied in the direction of opening between the bridge bodies, the hinge part will not deform. This has the effect of preventing the rivet body from loosening. By attaching the differently colored end tubes to the hinge base, it is possible to create a watch band with clearly colored hinge parts together with the bridge body.
