Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a watch band joint structure in which long metal wires are wound in parallel around a mesh core, or finely divided metal wires are attached in parallel to each other.

<Problems that this invention attempts to solve> A conical screw mounting hole is provided in a watch band in which metal wires are wound or adhered to a mesh core in parallel.
When forming a joint, conventionally the Utility Model 143320
As can be seen in Figure 1 of the publication, a pre-integrated joining part was brazed to the band end, but the solder overflowed and adhered to the surrounding area. In addition to being unsightly, it also has the disadvantage of discoloring the surrounding area, so the exposed part of the mesh core is provided at the end, similar to the so-called stacked board type watch band, in which board pieces with holes drilled in the mesh core are inserted in parallel. It is desired to attach the mating parts by welding.

However, in the case of watch bands in which metal wires are wrapped or adhered to a mesh core in parallel, the metal wires are thin, so the level difference at the exposed end of the mesh core is significantly shallower than in a layered plate band. Therefore, simply attaching the watch band to the upper plate and attaching the lower part to the upper plate causes problems such as insufficient strength and deformation or peeling. The present invention attempts to solve such problems.

<Structure of the invention> A watch band is made by wrapping metal wires around a mesh core in a parallel manner, or by adhering finely divided metal wires in a parallel manner to a watch band, and providing an exposed end of the mesh core, and winding the wire around the exposed end. The mounting allowance with folded parts for wrapping on both sides is wrapped and welded, the upper part extending from the mounting allowance is extended in front of the exposed end, and the two lower parts are formed with a mounting hole for a conical screw transversely formed. The parts are connected by a support plate, and the support plate is welded to the bottom of the mounting allowance, the lower part is welded to the bottom of the upper part, and the joining part is constructed by welding. be.

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

A long metal wire 2 is wound around a metal mesh core 1 in parallel,
Alternatively, the exposed end portion 1a of the mesh core 1 is formed by peeling off the metal wire 2 from a watch band 3 made by adhering and adhering the metal wire 2 cut into short pieces. The flat plate-shaped upper part 3 made of metal has a thin mounting allowance 4 extending along the upper surface of one side and having the same shape and thickness as the exposed end 1a. The installation allowance 4 is provided with folded parts 4a on both sides, and the installation allowance 4 is
is mounted on the exposed end portion 1a, the folded portion 4a is folded back to the back surface of the exposed end portion 1a, and the end surfaces are butted, and then the mounting allowance 4 and the folded portion are attached to the exposed end portion 1a by welding. 4a is attached, and then the lower part 5 is attached under the upper part 3 by contact welding. The lower part 5 consists of a pair of prismatic pieces 5b each having a conical screw mounting hole 5a formed transversely, and both pieces 5 are arranged in the middle of one surface.
A support plate 6 connecting between the pieces 5b and 5b is extended, and the support plate 6 is applied to the lower surface of the folding margin 4a, and both pieces 5b
These are placed on the bottom surface of the upper part 3 and attached by welding. All welding is spot welding.

In this way, a conical screw is used at the end of a watch band in which long metal wires 2 are wound around the mesh core 1, or finely divided metal wires are attached in parallel.
It becomes possible to attach the joint by welding.

<Effects of the invention> Since the invention is constructed as described above, even in a watch band in which metal wires are wound in parallel around a mesh core or finely divided metal wires are adhered in parallel to each other, the folded part can be attached to the upper part. We provided a mounting allowance for , provided a support plate on the lower part, wrapped the mounting allowance and folded part around the exposed end of the net core, and welded the support plate under the exposed end of the net core. Although the metal wire is thin and the height difference between the watch band and the other parts is shallow, the top surface remains flat and has sufficient strength, making it possible to use conical screws without fear of deformation or falling off. This has the advantage that the parts can be constructed by welding.
