JPS5853068Y2 - watch band - Google Patents

Description

[Detailed description of the invention] This invention relates to an improvement of a metal watch band.

Conventionally, the side pieces of such a band were formed by sequentially cutting a long board into the desired size and shape, so the outer corners of the side pieces were at right angles, and when worn on the arm, it looked like a dress shirt, suit, etc. There was a risk that the cuffs of underwear, stockings, etc. would get caught and be damaged.

This idea was devised to solve the above-mentioned problems, and by drawing and forming the side piece into a flat bag shape with an oval cross section, all the outer corners of the side piece were rounded. To provide a watch band which can surely prevent the cuffs of dress shirts, suits, underwear, etc., stockings, etc. from being damaged when worn on the wrist.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

As shown in the figure, the band of this invention consists of a center piece A press-formed into a flat cylindrical shape with an oval cross-section, a side piece B drawn into a flat bag-shape with an oval cross-section, and a center piece A.
A large number of longer connecting plates C having connecting portions 1 at both ends and connecting pins D having the same length as the connecting plates C are formed.

The connecting plate C has a front side connecting plate 2 and a back side connecting plate 3 overlapped with each other, and a side piece B is fitted into the corner of each connecting portion 1 that projects at right angles in the same direction at both ends thereof. The fitting portions 4 for the connecting portions 1 and 3 are respectively omitted, and a connecting hole 5 is formed approximately at the center of each connecting portion 1 of the back side connecting plate 3.

Then, the connecting plate C is inserted into one of the adjacent center pieces A, and the connecting pin D is inserted into the other center piece A so that both ends thereof are in contact with the end surface of the connecting part 1 of the connecting plate C. Then, insert the side pieces B from both ends of the connecting plate C and the connecting pin D, and press the approximate center of the back of each side piece B into the connecting hole 5 of each connecting part 1 of the connecting plate C. The components A, B, C, and D are combined and sequentially connected in a chain so that the protrusion 6 is fitted into the projection 6.

Further, as a connecting means between the side piece B and the connecting plate C,
A connecting hole 5 is bored in the connecting portion 1 of the connecting plate C, and this connecting hole 5
Although it is explained and illustrated that the protrusion 6 is inserted by pressing from the back surface of the side piece B, the invention is not limited to this, and the back surface of the side piece B and the connecting plate C can be connected by spot welding, caulking, etc. You may also do this.

Since this invention is constructed as described above, the connecting plates C and the connecting pins D are inserted through the adjacent center pieces A, respectively.
Since it can be connected sequentially by simply fitting the side pieces B from both ends of the body, assembly is not only extremely easy, but
By drawing and forming the side piece B into a flat bag shape with an oval cross-section, all the outer corners of the side piece B are rounded, so when worn on the arm, it can be easily attached to the cuffs of dress shirts, suits, underwear, etc., or stockings. It is possible to reliably prevent one equal force bow from being damaged.

In addition, by completely drawing and forming the side piece B into a flat bag shape, the strength of the side piece B is much stronger than that of conventional side pieces that are cut and formed from long plates, and the appearance is also better. It will be significantly better.

As explained above, according to this invention, when worn on the arm, it is possible to reliably prevent damage to the cuffs of dress shirts, suits, underwear, stockings, etc., and the strength of the side pieces is strong, and the appearance is The appearance is also very good, and furthermore, various effects such as ease of assembly can be obtained.
