Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a watch band.

"Prior art and its problems" This type of watch band is required to consider both functions such as strength and flexibility when wearing the watch on the wrist, and decorativeness in appearance such as design. .

Conventionally, as this type of watch band, there is a metal band in which, for example, a plurality of pieces formed by bending a stainless steel plate are connected by a connecting pin.

However, while a metal band with such a structure has the advantage that it does not spoil its appearance too much, since it is a combination of pieces made of so-called plate materials, the smoothness of bending of the connecting part is poor. In addition, the final finish must be applied after connecting multiple pieces in production, so the materials for the pieces are limited, and high-quality materials (such as gold) are used to improve the appearance. There were problems such as it was difficult to vary the material, bring out the high-class image of the material, and enhance the decorativeness. On the other hand, if a configuration is adopted in which multiple pieces made of different materials are connected to give a sense of luxury, this can be solved to some extent, but there is a dissatisfaction that the process becomes complicated and costs increase.

"Purpose of the invention and means for achieving the same" The purpose of this invention is to effectively solve these problems. In a watch band in which pieces are arranged alternately with decorative pieces, and a connecting pin for connecting the decorative piece and a connecting piece is inserted into the decorative piece so as to pass through the connecting piece, the decorative pieces are arranged opposite to each other. A through hole is provided into which a connecting pin is inserted, and a cylindrical body having a shape corresponding to the inner wall surface shape of the through hole is provided in the through hole, and the walls are cut inward on both sides of the cylindrical body. In addition to providing a locking piece that is raised up, the connecting pin is provided with a locking portion that is engaged with the locking piece when inserted into the decorative piece, and the connecting pin is After finishing, these are assembled using a connecting pin, and the connecting pin is prevented from coming off by the engagement between the locking portion of the connecting pin and the locking piece of the cylindrical body.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, this watch band is made up of decorative pieces 1 arranged horizontally, and decorative pieces 1 arranged alternately in rows at both ends of these decorative pieces 1. It is mainly composed of a connecting piece 2 and a connecting pin 3 that is inserted into each decorative piece 1 while passing through the connecting piece 2 and connects them, and the connecting pin 3 of each decorative piece 1 is inserted. A cylindrical body 4 that prevents the connecting pin 3 from slipping out is provided in the two through holes 1a.

The decorative piece 1 is formed in the shape of a pipe with a figure-8 cross section, in which two cylindrical bodies are arranged in parallel and connected together, and the two through-holes 1a extend along the length of the piece. They are arranged parallel to each other along the width direction. This can be obtained by, for example, forming stainless steel or its alloy into a long pipe shape by extrusion molding or the like, and cutting the pipe into a predetermined size.

Further, the connecting piece 2 is formed of a metal such as gold or silver into an elliptical flat plate that bulges in the minor axis direction, and a hole 2a through which the connecting pin 3 passes is provided in the flat plate. It is composed of
Holes 2a are arranged in two rows along the decorative pieces 1 with holes 2a overlapping each other at both ends of adjacent decorative pieces 1.

As shown in FIG. 3, the connecting pin 3 is formed into a cylindrical shape with one end inserted into the through hole 1a of the decorative piece 1, and its tip is engaged with the locking piece 4a of the cylindrical body 1. A locking portion 3a is provided, and the other end is formed into a cylindrical shape with a diameter larger than that of the one end.

On the other hand, the cylindrical body 4, which prevents the connecting pin 3 from coming out, is formed by punching out a flat plate having a cut and raised portion A, as shown in FIG.
This is pressed and rolled into a pipe shape corresponding to the shape of the inner wall surface of the through hole 1a, as shown in FIG. The cylindrical body 4 is installed in each through-hole 1a of the decorative piece 1 to prevent the connecting pin 3 inserted into the through-hole 1a from falling off.

To assemble a watch band having such a structure, as shown in FIG. The connecting pin 3 is inserted into the decorative piece 1 with the connecting piece 2 interposed at both ends, passing through the hole 2a of the connecting piece 2, and then the locking portion 3a and the locking piece 4a are engaged. Connect pieces 2 in sequence.
By fixing them to the decorative piece 1, they are connected to each other as shown in FIG. 1 and the like. In this case, the tip of the connecting pin 3 inserted into the cylindrical body 4 in the decorative piece 1 is connected to the locking piece 4 of the cylindrical body 4.
When the locking piece 4a crosses over the locking pin 4a, the locking piece 4a is pressed from inside and elastically deforms to expand outward, thereby easily engaging the connecting pin 3. Further, after these are engaged, the locking piece 4a closes inward due to its elastic force and can tightly engage with the locking portion 3a of the connecting pin 3, so that after the connecting pin 3 is inserted, Since it does not wobble and is supported in a securely held state, it is held in a stable state.

Note that by providing a connecting piece or a stopper for attachment to the watch body at the end where the decorative piece 1, connecting piece 2, and connecting pin 3 are connected in this way, the watch band is completed.

In addition, in the above-mentioned embodiment, the through hole 1a of the decorative piece 1, the connecting pin 3, the cylindrical body 4, etc. were each formed to have a circular cross section, but the present invention is limited to this embodiment. 4 cross sections rather than objects
It may be made into a square shape. Furthermore, the shapes of the decorative piece 1, the connecting piece 2, and the connecting pin 3 are not limited to those of the embodiment.

"Effects of the Invention" As explained above, the watch band of the present invention provides the following excellent effects.

(a) Pieces that make up the watch band (decorative pieces, connecting pieces)
are connected by a connecting pin that passes through the connecting piece from the side and is inserted into the decorative piece, so they can be assembled after finishing each piece, and the assembly work is easy. Cost can be reduced. In addition, since pieces made of different materials can be easily connected, it is possible to vary the appearance, bring out the high-class image of the material, and enhance decorativeness.

(b) Since the wall of the cylinder is cut inward to form a locking piece that engages with the locking part of the connecting pin, when the connecting pin is inserted into the cylinder inside the decorative piece, it will not lock. Since the locking piece elastically deforms outward, it is possible to reduce the resistance force during insertion, making it easier to attach the connecting pin, and the elastic force of the locking piece allows the connecting pin to be tightly engaged, thereby improving the connection. It can make it difficult for the pin to come out.

(c) Since it has a hinge structure with connecting pins,
It fits easily on your wrist when you wear the watch.
