Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a watch band piece.

<Problems that this invention aims to solve> Conventionally, this type of piece required cutting the hard piece part and forming connecting holes at alternate positions on both sides, which took a lot of time to process and was difficult to mass produce. There was a problem that was preventing the Therefore, as described in Japanese Utility Model Publication No. 54-37331, there has been a proposal to solve some of the above problems by forming a folded cylindrical part on the inner piece as a connecting piece, but this publication is only a folded piece. Because it stays against the back of the inner piece with a backing, when a tensile force is applied in the connection direction, the folded piece unfolds and expands or deforms the cylindrical part, which causes the pin to be inserted to loosen. There is a problem with extraction. The present invention attempts to solve such problems.

<Effects of the invention> This invention provides protrusions at alternate positions on both sides of the intermediate plate on which the upper plate is mounted in the connection direction, folds back the protrusions to form a connecting cylindrical part, and Following the folded end of the cylindrical part, a backing part is provided in an interlocking manner below the middle of the back surface of the intermediate plate, and the backing part is provided in the middle of the top surface of the lower plate which is backed and overlapped under the middle plate. There is a piece of a watch band characterized in that the paragraph part is sandwiched and covered.

<Example> Examples will be described based on the following aspects.

The intermediate plate 4 is provided with protrusions at alternate positions on both sides in the connection direction, and the protrusions are folded back to form the coupling cylindrical parts 2, 2', and 3.
2' makes the inside part of the folded end into a thin strip shape, extends to the full width of the intermediate plate 4, and backs it, and the other side cylindrical part 3
Coplanar meshing backing parts a, b, and c are formed across the wide extension part of the folded end. These interlocking backing parts a, b, and c are sandwiched and covered by a stepped part 5 provided at the middle of the upper surface of the lower plate 6 which is backed and overlapped under the intermediate plate 4. The upper plate 1 of the same shape is mounted on the upper surface of the intermediate plate 4, thereby forming pieces for a watch band having connecting cylinders at alternate positions on both sides.

This piece 7 has connecting cylindrical portions 2, 2' and 3 meshed with each other and arranged in parallel, and a pin 8 is inserted from one of the communicating cylindrical portions to form a watch band body 9 of a predetermined length.

In addition, as shown in FIG. 3, there are projecting parts 10, 1 on both sides of the upper plate 1 that cover half of the cylindrical parts 2, 2', 3.
0', the upper surface of each cylindrical portion in the connection shown in FIG. 1 is covered with the overhanging portions 10, 10' and is not visible from the upper surface.

<Effect of the invention> As described above, the pieces of the watch band are formed by folding back the protrusions provided on both sides of the intermediate plate 4 to connect the cylindrical parts 2, 2'.
and 3 can be formed, and the processing time can be significantly shortened compared to the conventional formation by cutting, resulting in the effect that the manufacturing efficiency can be dramatically improved. .

Moreover, these cylindrical parts 2, 2', and 3 have a backing part that engages and backs the bottom of the middle part of the intermediate plate. Since it is sandwiched and coated, it is significantly strengthened, and even if a strong tensile force is applied in the connection direction after forming the band body, or even if bending or twisting pressure is applied, each cylindrical part will not expand or deform. This has the effect of preventing the connecting pin from being pulled out. Moreover, since the lower plate 4 has a stepped part 5 on the upper surface of the middle part and is fitted and overlapped with the meshing backing part, regardless of the overlapping form of the upper plate and the following four pieces, as shown in FIGS. 1 to 3, Many effects are produced, such as a horizontal view of the three-layered structure of the upper plate, middle plate, and lower plate.
