Problems solved by technology

[0005] In the conventional watchband described in the above-mentioned Japanese Patent Application Laid-Open No. 7-136008, it is intended to increase the strength of the band length adjustment hole fitted with the stud, but it does not take into account, for example, the connection between the main body case of the watch and the watchband. Reinforcement of the part (around the spring post hole) that does not address the problem of the strap breaking from the spring post hole of this connecting part
[0006] Moreover, during the use of the belt, there arises the problem of peeling off of the outer coating due to so-called breakage or twisting of the belt

Embodiment Construction

[0049] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. figure 1 It is an exploded perspective view of a wristwatch with a watch band according to an embodiment of the present invention. In the present embodiment, the wristwatch 100 indicates the time by rotating hands (not shown) such as a second hand, a minute hand, and an hour hand, for example. Of course, a watch without hands may also be a watch with hands and a liquid crystal display to indicate the time.

[0050] The watch 100 has a main body case 1 formed in a hollow short column shape. The belt mounting parts 2 and 3 are formed on the outer peripheral part of the main body case 1. In addition, a plurality of operation buttons 4 are provided on the outer periphery of the main body casing 1, and the operation buttons 4 are used to input various operation instructions such as a time synchronization instruction. figure 1 Only one operation button 4 is recorded in....

Abstract

A band and a wristwatch which can greatly improve the main body strength and a method of making the band are described. The band main body (10) provided with a plurality of band length adjusting holes in the longitudinal direction is formed by a support layer (12b) made of carbon fibers. The support layer respectively has a first resin layer on the front surface and a second resin layer on the back surface. The support layers are respectively inclined at a prescribed angle such as 45 degrees along the extension direction of the carbon fiber bundles of the support layer relative to the longitudinal direction H and horizontal direction of the band main body (10). The strength of the main body of the band is greatly increased and the possibility of peeling of other members is prevented in advance in application when the band is broken or twisted.

Description

Technical field [0001] The invention relates to a belt, a watch and a method for manufacturing the belt. Background technique [0002] In recent years, resin materials have been used as watch straps and floating rings. Such resin-made watchbands and floating rings have been used for many years, so there is a problem of so-called breakage during use. The reason is believed to be that the resin absorbs moisture, mold, etc., causing performance degradation. As a countermeasure against this so-called fracture problem, a resin that can be used for a long time has been selected. However, only by the selection of resin, there is a limit to improving the strength of the belt. [0003] Therefore, a watch band in which carbon fiber woven fabric is embedded in a resin band as a reinforcing material has been developed. [0004] For example, currently, as shown in Japanese Patent Application Laid-Open No. 7136008, there is known a watch band composed of the following band material as all or a...
