Description

[Detailed explanation of the idea] About this watch band.

Traditionally, the materials for watch bands have changed along with the diversification of watch bodies.
Various materials such as leather, metal, and plastic have been developed and used depending on purpose, economy, etc.

Among these materials, metal and stainless steel are relatively superior in terms of durability and design, and are currently the mainstream for watch bands.

However, metal watch bands have complex structures that make it difficult to reduce costs, stainless steel has poor color change, and trying to reduce weight may reduce strength. It had its own flaws.

This idea was made with these backgrounds in mind,
The aim is to provide a watch band that solves the above-mentioned drawbacks by taking advantage of the characteristics of materials such as metal and plastic.

This invention will be described in detail below based on embodiments shown in the drawings.

In the illustrated example, the button indicated by the symbol 1 is a piece body, the symbol 2 is a connecting piece disposed between this piece body 1, and the button denoted by numeral 3 is internally attached to the piece body 1 button and the connecting piece 2. core material, code 4
What is shown with is a decorative pin attached to the core material 3.

The piece body 1 is formed by punching and bending a metal plate as shown in FIG.
A notch hole 13 is formed in the center of the top plate part 11, and connecting pieces 14 are formed at both ends of the notch hole 130, so that the bent piece 15 and the top plate part 11 communicate in the width direction of the band. It is configured such that a fitting hole 16 is formed therein.

The twisted connecting piece 2 is formed as shown in FIGS. 1 to 3 by bending a metal plate or the like in the same way as the piece body 1. an engaging piece 21 that engages with the inside of the core 3; and a clamping piece 2 that supports the core 3.
2 is provided.

Additionally, the core 3 is fitted into the fitting hole 16 of the piece body 1 and between the engagement piece 2F and the clamping piece 23 of the connecting piece 2, and faces the through hole 12 of the piece body 1. The entire body is made of an elastic soft or semi-hard plastic material, and a small hole 31 is formed at a position facing the through hole 12 of the piece body 1, and the engaging piece 21 and the clamping piece 22 of the adjacent connecting piece 2 are A notch 32 that fits is formed.

Furthermore, the decorative pin 4 is made of a machine screw with a pointed tip, colored plastic, jewelry, etc., and has a size that fits into and closes the through hole 12 of the piece body 1, and has a core material. It is fitted into the small hole 31 of 3 by means of screwing 1 or force fitting. 3 Figures 1 and 2 show a state in which a plurality of these parts are connected, and Figure 3 shows a state in which a plurality of these parts are connected. indicates its assembled state.

To explain how to assemble a watch band, the core material 3 is fitted into the fitting hole 16 of the uncut piece body 1 as shown by the dashed line in FIG. 3, the through hole 12 and the small hole 31 are aligned, and then In a state where the pieces 1 and the core members 3 are combined, a plurality of sets are aligned, and the engaging pieces 21 and the clamping pieces 22 of the connecting pieces 2 are inserted into the two notches 3.
2, the piece body 1, the connecting piece 2,
A plurality of sets of core materials 3 are connected.

Next, the engaging piece 21 and the clamping piece 22 are each bent in the direction of the arrow in FIG. 3.

Due to this bending force, the engagement piece 21 of the connecting piece 2 is
It is in a state where it is wrapped around the connecting piece 14 of the piece body 1, and it is in a state where it can rotate freely due to the gap and roundness of this part.

Next, the top plate portion 11 of the piece body 1. The decorative pin 4 is attached to the bridge body 1 by polishing the connecting piece 2, etc., cutting both sides in the width direction, attaching a stopper, and attaching a mounting piece to the watch body. It fits into the small hole 31 of the core material 3 through the through hole 12.

In the illustrated example, the decorative pin 4 is shaped like a small screw, so the small hole 3
1 will be screwed in while being elastically deformed.

In the case where the tip of the decorative pin 4 has a needle-like point, the core material 3 may be fitted while being elastically deformed.

At this time, the through hole 12 of the piece body 1 guides the fitting of the decorative pin 4, and also supports the head of the decorative pin 40 after fitting to prevent the piece body 1 and the core material 3 from shifting in the width direction. It has the effect of

In the illustrated example, the core material 3 is inserted into the piece body 1 and the connecting piece 2, but if the piece body 1 itself has a connecting structure and the connecting piece 2 can be omitted. Of course, it can also be applied to

As is clear from the explanation on the ground, this idea involves forming a through hole in the front plate of the piece body to be connected, and inserting a decorative pin into the elastically deformable core material inserted into the piece body through the hole. Since it is designed to be attached in one piece, the engagement part that requires strength is handled by a piece made of metal, etc., and the core material is made of a material such as plastic that has a smaller specific gravity than metal. The weight can be reduced by placing the small decorative pin through the hole in the piece body, which improves the design and prevents misalignment between the piece body and the core material, and it is extremely easy to assemble. This has effects such as being able to reduce costs.
