JPS5853048Y2 - Core material for leather watch bands - Google Patents

Description

[Detailed description of the invention] This invention improves the core material of leather watch bands, making it possible to make this type of band extremely thin.The feature is that the core material is made of a thin mesh made of stainless steel. This is because the board 4 and the thin cloth 5 are bonded together.

The band, which is made by polymerizing a leather front piece 1 and a leather back piece 2 sandwiching a core material 3, has been required to be made thinner and thinner as watch cases have become thinner in recent years. A core material made of paper or reinforced paper is used, and these core materials have zero strength.
, it cannot be made thinner than about 7 mm,
Therefore, as long as such a core material is used, there is a limit to how thin a leather band can be made.

According to the present invention, by laminating the 0.04 mm stainless steel mesh plate 4 and Q, and the 1 mm fabric 5, the core material 3 is 0.04 mm.
It can be made as thin as 14 mm.

If the core material 3 of the present invention is used in this way, a leather watch band can be made dramatically thinner and meet the above requirements.

Further, by bonding the stainless steel mesh plate 4 and the fabric 5, it is possible to prevent the edges of the mesh plate 4 from unraveling.

Note that the fabric 5 is preferably a bias fabric that does not stretch in the longitudinal direction or the width direction.

Figure 1 shows bias fabrics 5, 5 with a thickness of about 0.1 mm on both sides of a mesh plate 4 made of stainless steel with a thickness of about 0.04 mm.
The figure shows a core material 3 constructed by laminating .

FIG. 2 shows a core material 3 in which a bias fabric 5 is applied and bonded to only one side of the mesh plate 4 described above.

The core material in the case of FIG. 1 has a thickness of about 0.24 mm, and the core material in FIG. 2 can be made even thinner to about 0.14 mm.

In both cases, the core materials are made of different materials and do not expand or contract in either the longitudinal direction or the width direction.

Further, since the entire surface of the mesh plate 4 is fixed by pasting the bias fabric 5, there is no fear that the edge portions will come undone.

As described above, by using the core material of the present invention, the watch band of the type in which the front piece 1 and the back piece 2 made of leather are polymerized by sandwiching the core material 3 can be made extremely thin with sufficient strength. This has the effect of meeting the above requirements.
