Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wristwatch band, and particularly to a bridge structure in which bridge bodies are sequentially connected.

As a type of watch band, a recess is provided on the back side of the edge piece body, a connecting piece is engaged in this recess, a pin is inserted into the connecting piece through a through hole provided in the edge piece body, and the edge piece body and the connecting piece are connected. There is a band that is sequentially combined. In such a band, when assembling the band, the edge piece and the connecting piece must be finished integrally, making the assembly process difficult, requiring long processing time, and increasing costs. Furthermore, in terms of design, it had to be formed into a monotonous continuous piece band, which had the disadvantage of lacking in luxury.

The present invention aims to provide a bridge connecting structure in which the edge piece and the connecting piece constituting such a wristwatch band are structured not only for simple connection but also for decorative purposes. .

In order to achieve the above object, the wristwatch band according to the present invention has both side walls, an edge piece body having a concave groove passing through the band in the longitudinal direction on the back side, and a width that is approximately equal to the lateral width of the edge piece body. and a connecting piece having a main body and a connecting part protruding from both sides of the main body and fitting into a groove of the edge piece body, and a connecting piece having a main body having a main body having Make a hole,
This is characterized in that the connecting portions are inserted into the grooves of adjacent edge piece bodies, and the connecting shafts are engaged with the opposing holes, thereby connecting the edge piece bodies and the connecting piece so as to be able to rotate in sequence.

This will be explained below with reference to the drawings.

As shown in FIG. 1, one connection structure of a watch band includes a plurality of edge piece bodies 1, a connecting piece 2 connected so as to be exposed between each adjacent edge piece body 1, and the edge piece bodies 1. The connecting shaft 3 rotatably connects the connecting piece 1 and the connecting piece 2. The wristwatch band as a whole is formed into a connecting structure in which the edge pieces 1 and the connecting pieces 2 are arranged alternately on the front side and each can be expressed in a desired design.

That is, the edge piece body 1 has a substantially rectangular planar shape as shown in FIGS. 1 and 2, and has a groove 6 provided on the side wall 5 at the lateral end of the band and on the back side and penetrating in the longitudinal direction of the band. A locking hole 7 corresponding to a shaft hole 9 provided in a connecting portion 8 of a connecting piece 2, which will be described later, passes through both side walls 5 thereof. The connecting piece 2 has approximately the same width as the lateral width of the edge piece body 1, has a height that is the same as or slightly protrudes from the exposed surface 4 of the edge piece body, and has a surface that is It consists of a main body 10 having an arcuate cross-sectional shape and connecting parts 8, 8 which protrude from both sides thereof and have tapered surfaces T formed on their upper surfaces, and the connecting parts 8, 8 are formed so as to be able to be fitted into the groove 6. has been done. Also, holes 9,
9 is bored, and this hole 9 is connected to the groove 6 of the edge piece body 1.
The connecting portion 8 is positioned so as to be coaxial with the locking hole 7 when the connecting portion 8 is inserted into the locking hole 7.

FIG. 3 shows a cross-sectional structure showing a state in which the adjacent edge piece bodies 1 and the connecting pieces 2 are connected, and as described above, the connecting pieces 2 are connected to each other from below in the concave groove 6 of the edge piece body 1. The parts 8, 8 are inserted. A coupling shaft 3 having an end portion 11 formed with a small diameter is inserted into the shaft hole 9 and the locking hole 7 and is press-fitted into the locking hole 7.

In this way, the adjacent edge pieces 1 and the connecting pieces 2 are rotatably connected via the connecting shaft 3 at the connecting portions 8 of the connecting pieces 2 to form a series of wristwatch bands.

Generally, the connecting piece 2 and the edge piece body 1 are processed separately, and after the connection and assembly, the surfaces are further subjected to integral finishing processing, but in the case of the present invention, the structure is simple, so it can be easily formed by cutting. Since the connecting shaft 3 only needs to be press-fitted when connecting, it is possible to finish the surface separately and form them separately.In particular, it is possible to create a design effect by changing the upper surface of the protruding part of the main body 10 of the connecting piece 2 to a shape other than an arc shape. It has a planar shape, uneven pattern, and cut carvings, and can also be changed to different colors, and has a surface finished structure with a metal plating treatment different from that of the surface of the edge piece body 1. is also possible.

Due to the above structure, when assembling, a plurality of edge piece bodies 1 and connecting pieces 2 are formed by cutting, and then decorative finishing is applied to each separately, and then connected between adjacent edge piece bodies 1. Both connecting parts 8, 8 of the piece 2 are inserted into the grooves 6, 6 from below. Next, after positioning the shaft holes 9, 9 and the locking holes 7, 7 of both connecting parts 8, 8 fitted into the mutually adjacent edge pieces 1, 1, the connecting shaft 3 is inserted from both side walls 5, 5. It may be press-fitted into the locking holes 7, 7. In this manner, each edge piece 1 is rotatably connected to the shaft hole 9 of both connecting portions 8 of the connecting piece 2 by the connecting shaft 3. In this way, a set of chained bendable bands is formed.

In the above-mentioned embodiment of the present invention, the coupling shaft 3 is a press-fit pin, but the same effect can be achieved by using a coupling screw with a thread machined on the press-fit portion, but in this case, the locking of the edge piece 1 The hole 7 may be a screw hole so that each connecting piece 2 itself can be replaced in various ways.

As is clear from the above, according to the present invention, the surfaces of the parts can be manufactured separately through simple cutting of metal materials, and a decorative wristwatch that is inexpensive, easy to assemble, and rich in design effects can be produced. You can get a band for it.
