Description

[Detailed explanation of the idea] This invention relates to a watch band.

In the past, a wide variety of watch bands have been devised and put into practical use depending on their purpose, but recently, watch bands that are more decorative or aesthetically superior than their original function as a watch band, that is, designs There has been a strong demand from the general public for highly effective products. Particularly in metal bands, stainless steel is often used because it is lightweight and resistant to corrosion, but it has drawbacks such as poor color change.

This idea was created in view of the above circumstances, and aims to improve the design effect and simplify the structure.
Moreover, it is an object of the present invention to provide a watch band that is easy to manufacture, inexpensive, and robust. This invention will be explained below with reference to the drawings.

Reference numeral 1 in the figure is a connecting upper piece made by punching and forming a metal plate material into a substantially H-shape.The cross section is U-shaped, and there are notches 2 on both side edges 1a and 1b.
The substantially middle portion of the upper surface 1c is formed to be slightly narrower, and two opposing locking pieces 3, 3, . Further, reference numeral 4 denotes a lower connecting piece, which has a U-shaped cross section similarly to the upper connecting piece 1, and has notched portions 5 provided on both side edges 4a and 4b in correspondence with the notched portions 2. The bottom portion 4c has a plurality of locking holes 6, 6 into which the locking pieces 3, 3, . . . are inserted.
... has been drilled. The dimensions of this locking hole 6 are such that between the locking hole edges 6a, 6a in the thin width direction, the locking piece 3a,
The length between the locking hole walls 6b and 6b in the longitudinal direction is set to match the length of both ends of the locking piece 3 in the longitudinal direction. Here, the bending line 1 of the connecting upper piece 1 shown in FIG. 1 and FIG.
d, 1d and the bending lines 4d, 4d of the connecting lower piece 3
The respective intervals are set to be a little more than twice the thickness of the plate material, and the plates are bent at right angles along bending lines 1d and 4d. In this case, in the connecting upper piece 1, the width of the upper surface 1c is the bending line 1d, 1d.
The notch 2 is formed so that the gap is smaller than the gap between the two, and when the two side edges 1a and 1b are arranged in contact with each other, a window hole 7 is provided. The height of the locking piece 3 is set so that the dimension between the bending line 1e and one edge 1f is three times the thickness of the plate material. A large number of the above-mentioned connecting upper pieces 1 and connecting lower pieces 3 are formed, and the inner walls of the side edges 1a, 1b, 4a, 4b of the connecting upper pieces 1 and the connecting lower pieces 4 are aligned in a third direction.
As shown in FIGS. 6 to 6, the connecting pieces are engaged with each other by meshing with each other. A decorative band 8 is interposed between each connecting piece, and this decorative band 8 is made of synthetic leather such as vinyl leather and is fixed by being sandwiched between the notches 2 and 5 of each connecting piece. In this way, each connecting piece is engaged with the decorative band 8 between the locking pieces 3, 3.
... are inserted into the locking holes 6, 6... to protrude, and bent 90 degrees inward along the bending lines 1e, 1e... to bring them into close contact with the locking hole edge 6a and side edges 1a, 1b, respectively. Concatenated.

In addition, in the embodiment, two sets of locking pieces are provided for one connecting upper piece, but three or more sets may be provided, and the locking holes for these pieces may be provided individually or several holes may be drilled in common. It may be something like that.

A watch band constructed in this manner has smooth surfaces on both sides, but is generally used with the upper connecting piece 1 facing forward as shown in FIG. At this time, the decorative band 8 can be seen through the window hole 7 continuous to the upper surface of the band, and the band surface has a three-dimensional color change. In addition, since the whole is integrated into a plate shape, it does not slide along the longitudinal and width directions, and there is little slippage or rattling, so it can be firmly connected. Due to the small gap, the whole can be curved into an arc shape on either side.

In addition, if the cosmetic band 8 is prepared in several colors,
By combining it with a watch or a buckle (not shown), it is possible to decorate the band surface with a change in color.

As explained above, the watch band according to this invention has upper connecting pieces and lower connecting pieces bent in a U-shape in cross section, which are alternately arranged with the inner surfaces of their side edges facing each other, and In a watch band in which a locking piece formed on a side edge of the upper piece is connected by engaging with a locking hole formed on a side edge of the lower connecting piece, the connecting upper piece is attached to each side edge of the connecting piece. A notch is formed between the connecting lower piece to allow a flexible band-shaped decorative band to be inserted, and the central part of the connecting upper piece is formed to be narrower than both ends so as to form a window hole when connected. Because of this configuration, it is easy to manufacture and can be mass-produced at low cost. In addition, due to the flexibility peculiar to metal plate materials and the minute gaps at the connecting points, not only can it be used by bending it to either the front or the back, but also the metal band can be It has excellent design effects, such as being able to decorate with color changes.
