[Industrial applications]

 INDUSTRIAL APPLICABILITY The metal band element of the present invention can be used to obtain a watch band that is firmly bonded by being inserted into a connecting hole using a pin.

[0002]

[Prior Art]

 Conventionally, this kind of thing is as follows. The “method for producing a stainless steel metal band” filed by the applicant as Japanese Patent Application No. 2-4736 is a stainless steel rod in which two or more semi-circular recessed tanks are provided on the bottom surface by applying pressure to stainless metal to extend and spread it. After forming the unfinished product, the unfinished product of the two stainless steel rods was put together with the semicircular recess facing each other and welded with solder to form a stainless steel rod having two or more pin holes. This is a manufacturing method in which stainless steel rods are cut and cut to form small unit blocks, and the pin holes of these small unit blocks are connected by pins. In addition, in Japanese Patent Application No. 2-4737, “Stainless Metal Band Manufacturing Method”, stainless steel is compressed with a punch press and two or more rows of parallel semi-circular concave tanks are engraved on the bottom surface. The two unitary lumps are formed into a unitary lump, and these two unitary lumps are put together in a model with the semicircular concave tanks facing each other and welded with solder to form a unitary lump with two pin holes. The method for producing a metal band is configured such that these unit blocks are connected to each other by pin holes in the unit block to obtain a metal band. In these two inventions, a pin is used to insert into a hole for connection, and the pin is engraved with a non-slip pattern.

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. The pins are a little cumbersome in manufacturing, and if they are not imprinted with a non-slip pattern, they will not be fixed firmly, and at the same time it is very inconvenient to take them out. Once taken out, it cannot be used repeatedly.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

That is, the present invention is composed of the element part 2 and the connecting pin 3, and the element part is composed of one half element 2A and the other half element 2B which are formed by the press method, and the one half element. In the structure in which the inner surface of the element 2A and the inner surface of the other half element 2B are joined together, one half element 2A has a planar U-shaped connecting recess at the center of the front side and a rear half. A planar U-shaped connecting protrusion is formed at the center of the side, and front and rear semi-circular grooves 2A1 and 2A2 are formed in parallel on the inner surface side of the half element 2A. A semi-spherical or conical projection 2A3 is provided in one semi-circular groove 2A1 of 2A2, and the other half element 2B has a planar U-shaped connecting recess at the center of the front side. A flat U-shaped connecting protrusion is formed in the center of the rear side, and The front and rear semicircular grooves 2B1 and 2B2 are formed in parallel on the inner surface side of the child 2B, so that the front and rear holes 2C and 2D are formed in the element portion 2 by the abutting semicircular grooves, and , The projection 2A3 is projected to one side of this hole, and the connecting pin 3 is made of stainless steel wire, and its length is almost the same as the length of the element part 2. Has ring-shaped grooves 3A and 3B formed at positions corresponding to the semicircular grooves, and when connecting the respective element parts 2, insert the connecting pin 3 into the holes 2C and 2D of the element part, and connect them. The metal band element is configured so that the projection 2A3 is projected and locked in the ring-shaped groove of the pin 3.

【Example】

 Examples will be described with reference to the drawings. Reference numeral 1 is a metal band element of the present invention, which is composed of an element portion 2 and a connecting pin 3. First, referring to FIGS. 1 and 2, the element portion 2 is composed of one half element 2A and the other half element 2B formed by a pressing method, and the inner surface of the one half element 2A, After being brought into contact with the inner surface of the other half element 2B, they are connected by an adhesive method or a bolt connecting method. One half element 2A is formed with a planar U-shaped connecting recess at the center of the front side and a planar U-shaped connecting protrusion at the center of the rear side, and at the inner surface side of the half element 2A. And the front and rear semi-circular grooves 2A1 and 2A2 are formed in parallel with each other, and a semi-spherical or conical projection 2A3 is projected by pressing in one of the semi-circular grooves 2A1 and 2A2. It is set up.

Further, the other half element 2B is formed with a planar U-shaped connecting concave portion at the center of the front side and a planar U-shaped connecting protrusion at the center of the rear side, and the half element 2B is also formed. Front and rear semi-circular grooves 2B1 and 2B2 are formed in parallel on the inner surface side by press working. Although not shown in the drawing, hemispherical or conical projections can also be formed by pressing in this semicircular groove 2B1. For this reason, front and rear holes 2C and 2D are formed in the element portion 2 by the abutting semicircular grooves 2A1, 2B1, 2A2 and 2B2, and the protrusion 2A3 projects into the hole 2C.

As shown in FIG. 3, the connecting pin 3 is formed by processing a stainless wire, and its length is substantially the same as the length of the element portion 2. The connecting pin 3 has semicircular grooves 2A1 and 2B1. Ring-shaped grooves 3A and 3B are formed at positions corresponding to which, and since the diameter of the connecting pin 3 is slightly smaller than the diameter of the holes 2C and 2D, the connecting pin 3 can be appropriately loosened. It can be inserted into the holes 2C and 2D of the section.

Therefore, as shown in FIGS. 4 and 5, when connecting the respective element portions 2, the connecting pin 3 is strongly struck and inserted into the holes 2C, 2D of the element portions. In this case, when the connecting pin 3 is forcibly passed through the projection 2A3 in the hole 2C, the projection 2A3 projects into the ring-shaped groove 3A and is locked. By continuing such an operation for an appropriate number of element parts 2, each element part 2 is connected to form a metal band for a timepiece. If the connecting pin 3 needs to be removed, it is a rod with a pointed tip, and the protrusion can be separated from the ring-shaped groove in the connecting pin 3 by simply pushing one end surface of the connecting pin 3, so The pin 3 can be pushed out of the hole.

The operation will be described together with the effect.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. The connection pin and the element part are easy to manufacture due to their configuration, and can be processed quickly. The connection between the connecting pin and the element portion is also extremely easy and reliable. Moreover, the connecting pin and the element portion can be easily separated and disassembled, and can be repeatedly used no matter how many times they are separated and disassembled.
