Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a watch band composed of a molded plastic substrate and a metal plate wrapped around the core plate of the substrate.

<Problems to be solved by this invention> Conventionally, watch bands made by connecting block pieces require a lot of steps and assembly, as they are connected by forming connecting holes in each block piece and inserting pins. In particular, when an adjustment piece for length adjustment is also provided, the problem becomes even more complicated, and a solution to this problem is desired.

<Structure of the invention> The present invention has a band board integrally molded from plastic, which has a cylindrical part for pin insertion on both sides, or a core plate part for length adjustment on the negative side through which the pin can be inserted. By wrapping a metal plate around the outer surface of the core plate part and the adjustment core plate part of this board, a watch band in the form of connected block pieces can be easily obtained.
This satisfies the above requirements.

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

Fig. 6 shows a synthetic resin integrally molded band substrate 5, which has cylinder parts 1 and 1' arranged at both ends, and a rectangular core plate part 2 parallel to each other with two short connecting parts 8 sandwiched between them. An example of a watch band is shown in which a metal winding plate 6 having a notch 9 provided on the side to avoid the connecting part 8 is wound around the outer surface of each core plate part 2 as shown in FIG. ing.

By abutting each winding plate 6, the upper surface of the joint part 8 is hidden, creating a beautiful watch band.

This watch band is attached to a watch case and a stopper (not shown) by inserting pins 7 into the cylindrical parts 1 and 1' on both sides.

FIGS. 1 to 5 show a band board 5a and a watch band in which several length-adjusting core plate parts 2a are arranged in parallel so that a pin 7 can be inserted into the terminal end of the core plate part 2.

The core plate portion 2a for adjustment has an open groove 3 between the parallel plates 4 and 4', and the pin 7 can be inserted into the open groove 3.

Between the core plate parts 2a are two joint parts 8c and a bottom joint part 8.
It is connected at a.

The band board 5a has the above shape, that is, the rectangular core plate part 2 is parallel to the cylindrical part 1 sandwiching the two short connecting parts 8, and a plurality of core plate parts 2a for adjustment are arranged in parallel. It is integrally molded from synthetic resin, and a metal winding plate 6 is wound around the outer surface of each core plate part 2 and 2a, so that the adjustment piece part 2a/2a is formed as shown in FIG.
A watch band consists of several pieces arranged side by side.

Note that a removable filler metal 10 is inserted into the adjustment piece portion 2a' through which the pin 7 is not inserted to prevent melting and collapse due to dents or the like.

When the band is long, the length of the adjusting piece 2a' is cut off along the dotted line A--A as shown in FIG.

<Effects of the invention> As described above, the watch band with the metal block pieces and the length adjustment piece is made using the extremely simple procedure of winding the winding plate around the synthetic resin integrally molded substrate and the core plate, which prevents pieces from coming off. This has the effect of making it robust and easily obtainable without fear.
