Description

[Detailed explanation of the invention] This invention relates to a leather watch band, and its purpose is to make the watch band thinner to match the trend toward thinner watches, while also increasing the strength and tension of the watch band. The purpose is to try to strengthen it.

Conventionally, leather bands have been formed by inserting an intermediate material called a sponge-like floor material between the front and back pieces, so it is inevitable that the band will become a part, and it can quickly respond to the thinning of the watch side. The disadvantage has arisen that it is not possible to

Therefore, attempts have been made to insert a thin metal plate with strength and tension equal to or higher than that of the flooring material, but since the leather pieces on the front and back sides and the metal plate are qualitatively different, there is no way of adhering them together. Even if you pay attention to this, the front and back pieces will not adhere partially,
Alternatively, it has the disadvantage that it peels off in places, causing sagging and wrinkles.

The present invention eliminates such drawbacks, and will be explained in detail with reference to the accompanying drawings. FIG. A sword tip side band 6 formed by backing and bonding one end in advance, inserting a metal mesh plate 5 between the front and back pieces 1 and 3, and bonding with high frequency.
In addition, in Figure 1B (d), both ends of the backing piece 3 are backed and glued to the back side folded parts 2 and 2' provided at both longitudinal ends of the front piece 1 and the backing piece 3 to form a ring shape. A locking side band 7 is shown which has been formed, a metal mesh plate 5 is inserted, and high frequency bonding (thermal pressure bonding) is performed.

The metal mesh plates 5, 5' to be inserted are formed by punching a very thin metal plate material such as titanium alloy to a thickness of about 0.1 mm between upper and lower dies to have a relatively rough mesh.

The one to be inserted into the tip side band 6 has a back folded part 4 at one end of the longitudinal side and is placed inside the back side folded part 2 of the front piece 1, and the one to be inserted into the locking side band 7 has a back folded part 4 at one end of the longitudinal side. Back side folded parts 4, 4' are provided at both ends and are fitted inside the back side folded parts 2, 2' of the front piece 1.

Note that the metal mesh plate 5 to be inserted may be coated with rubber or the like on both the front and back surfaces to prevent sparks during high-frequency bonding.

In addition, the one inserted into the tip side band 6 has larger holes 8 arranged in parallel to make it easier to form a stop hole 9 to be drilled later.

The watch band thus formed has a metal net 5 interposed between the front and back pieces made of leather, and its strength and tension make it a thin, tight and neat band.

Although the metal mesh plate 5 has poor consistency and especially poor adhesion between the front and back pieces 1 and 3 made of leather, the metal mesh plate 5 Since it is held by the adhesive inner surfaces of the front and back pieces, there will be no partial adhesion failure or peeling that occurs when inserting a metal plate, so there will be no sagging or peeling on parts of the front and back pieces. Creation of wrinkles is also prevented.

In addition, since the metal mesh plate 5 is provided with folded parts 4 and 4' and is fitted inside the folded parts 2 and 2' of the front piece 1, the watch side mounting hole formed by the folded parts 2 and 2' is 10 and the lock attachment hole 11 can be strengthened.

In this manner, the present invention has the effect of providing a thin, firm and reinforced leather watch band that is responsive to the trend toward thinner watches.
