Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to a watch band structure.

[0002]

2. Description of the Related Art A hole is formed in an outer piece body and a pin is pressed into the hole.

[0003]

[Problems to be Solved by the Invention] The process of drilling a pin for the outer piece body is accompanied by difficulties such as accuracy and man-hours. There were many limiting factors in the dimensions of.

[0004]

[Means for Solving the Problems] Two parallel pin members arranged at intervals are connected to each other by a plate member to form an intermediate piece, and a rectangular hole is formed in a plate portion between the pin members. The watch band has a structure in which the outer piece body is welded to the middle piece through the plate portions from both sides of the pin member at both ends of the pin member, and the piece is connected through the middle piece through the rectangular hole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Here, the size of each drawing and the size and relative size between each drawing are for explaining the invention, and do not necessarily follow the actual size. FIG. 1 shows an intermediate piece 20 and four outer piece bodies welded to the left and right end portions of the piece from above and below. The figure shows four body portions which are moved in parallel around the middle piece and are welded to each other. 10a, 10b, 10c and 10d are shown. Here, the left body parts 10a, 10c sandwich the left side plate part 22 of the middle piece 20, and sandwich the left end parts of the circular parts 21, 21 ', and the semicircular grooves 11a, 11a', 11 of the body parts.
c and 11c 'are fitted from above and below and are integrally welded together by the projections 12a and 12c extending in the band width direction. Similarly, the right body parts 10b and 10d also sandwich the right side plate part 22 'and sandwich the right end parts of the circular parts 21 and 21' to form the grooves 11b and 1d.
1b ', 11d and 11d' are fitted from above and below and are integrally welded by the projections 12b and 12d. Here, the protrusions 12a to 12d do not have to be continuously formed, and may be formed by cutting in consideration of welding current and welding strength.

Next, FIG. 2 shows a rectangular hole 23 of the intermediate piece 20 in FIG.
1 shows one of the end pieces 31 or 31 'which is inserted into the hole 23 and the other end of which is inserted into the hole of the adjacent piece so that the end portions 31 and 31' are projected. It is closed to the position where it fits together, thus connecting the pieces one after another to complete the entire length of the watch band.

FIG. 3 shows an upper middle piece 41 and a lower middle piece 41 'which are divided into upper and lower parts, and two grooves 43a, 43b, 43a' of approximately semicircular cross section are respectively formed on the dividing surfaces 46, 46 '. ，
43b 'is formed, and the same protrusion 45 as the protrusions 12a to 12d is provided on either the upper or lower split surface. First, the upper and lower grooves 4 are formed in any of the circular portions 21 and 21 'of the middle piece of FIG.
3a, 43a 'or 43b, 43b' are fitted, and the same work is performed on the adjacent piece so that the central dividing surfaces are aligned and welded by the protrusions. At this time, the outer portions of the split surfaces 46 and 46 'are fitted into the holes 23 of the intermediate piece and the pieces are connected so that there is no rattling or displacement.

[0008]

[Effect of the Invention] Since the drilling process for the pin is unnecessary, the processing time and the processing cost can be reduced.

The step of forming the groove and the step of forming the circular portion and the rectangular hole in the intermediate piece are simple, and highly accurate work can be performed in general.

When using the divided middle piece of FIG. 3,
It is possible to provide a textured watch band.

[Brief description of drawings]

FIG. 1 is a perspective view in which an intermediate piece is centered and an outer piece body to be welded thereto is arranged in a relative assembly position relationship around the middle piece;

FIG. 2 is a perspective view of a plate winding middle piece before being closed;

FIG. 3 is a perspective view of a middle piece of a divided structure,
