Description

[Detailed description of the invention] This invention relates to a watch band in which pieces are connected by a shaft.The purpose of this invention is to firmly connect the pieces, improve the feeling of wearing, and easily connect the pieces. .

An example of the invention will be explained based on the drawings.
The watch band of this invention has a plurality of intermediate pieces 2 arranged in the lengthwise direction of the band and supported on both sides adjacent to each other by a first shaft 1; They are arranged opposite to each other on both sides in the band width direction of the piece 2, and are supported by a second shaft 3 and a third shaft 4, which pass through the intermediate portion of the intermediate piece 2, on both opposing sides. It is composed of pieces 5 on both sides.

In the embodiment, the intermediate piece 2 has an upper piece 6 and a lower piece 7 fixed to each other by spot welding or the like, and is fixed to both sides of the upper and lower pieces by spot welding or the like.
It is composed of upper and lower overlapping pieces that are fitted adjacent to each other and have a cylinder 8 supporting the first shaft 1, and horizontal holes 9, 9 for passing through the second and third shafts 3, 4. There is.

The pieces 5 on both sides are the second pieces. The horizontal hole 10 of the third shaft 3, 4,
It is made up of solid pieces that form 10 pieces.

The second shaft 3 and the third shaft 4 are press-fitted into the horizontal holes 10 and 10, or the tips of the shafts 3 and 4 are made to protrude from the horizontal hole 10 and the tips are caulked, etc.
It is fixed to the pieces 5 on both sides by an appropriate method.

Regarding the configuration of each piece 2, 5, a solid piece is used for the intermediate piece 2, a top and bottom overlapping piece is used for both side pieces 5, and the tube 8 is exposed on the top surface of the band or decorative pieces are buried. You can change it as appropriate, such as adding more.

In a watch band, the pieces must rotate by the necessary angle depending on the user's arm, causing the band to curve. However, in conventional watch bands, the middle piece 2 and the pieces 5 on both sides are simply the second piece. , since it is only supported by the third axes 3 and 4, the rotation angle Y of the piece increases, the band curves more than necessary, and the band is unstable when wrapped around the arm, making it uncomfortable to wear. There is. Furthermore,
Because the rotation angle Y is large, the upper ends 11 on both sides of the piece stand up, damaging clothing. Also, with long-term use, the shafts 3 and 4 may become deformed, and the fitting between the shaft and the hole may deteriorate. be. In order to prevent unnecessary rotation of the piece, there is also a watch band in which the lower ends 12 of both sides of the piece are brought into contact with each other, but this has the drawback of biting the hair. Further, in the conventional watch band, the pieces 2 and 5 are connected at the same time by the shafts 3 and 4, and therefore, skill is required for the connection work.

However, in the watch band of this invention, in addition to pivoting the intermediate piece 2 and both side pieces 5 on the second shaft 3 and the third shaft 4, the two adjacent sides of the intermediate piece 2 are supported on the first shaft 1. By supporting the pieces 2 and 5 with the shafts, unnecessary rotation of the pieces 2 and 5 is prevented, and the band is appropriately curved, making it comfortable to wear.
Each piece can be firmly connected by the 4 pivots. Furthermore, when connecting the pieces, first the intermediate piece 2 is connected, and then the pieces 5 on both sides can be connected. Since the pieces can be connected in two steps, the connecting work can be facilitated.

Regarding the rotation of the piece and the curvature of the band of this invention,
To explain based on Fig. 2, the radius of curvature of the band is approximately 20 mm, and the distance X between axes 3 and 4 is approximately 3 to 4 mm.
mm, the rotation angle Y between the adjacent pieces 2, 2 and 5, 5 can be sufficiently curved at about 20 degrees, and the shaft 1 and the cylinder 8
Further, by providing an appropriate gap between the shafts 3, 4 and the hole 10, a rotation angle Y of about 20 degrees can be sufficiently obtained.
Note that the above numerical values are illustrative of standard numerical values, and are not intended to limit the numerical values.

As described above, this invention can achieve the purpose and provide an excellent watch band.
