Description

  The present invention relates to a slide structure used as a slide-type lock mechanism or the like incorporated in a band fastener.

  Recently, a ceramic material has been considered as an option as a material for a band fastening device which is a connecting device for band-shaped chain members such as wristwatch bands and bracelets. In order to avoid allergies caused by nickel (Ni) -based metal materials generated by contact with the skin, stainless steel and titanium-based metal materials have been adopted as the material of the intermediate fastener, This is because the titanium-based metal material could not obtain sufficient satisfaction in terms of luxury and function.

  When a ceramic material is selected as the material of the slide structure, which is a slide-type locking mechanism incorporated in the band fastener, the ceramic material is far more than various surface treatments on stainless steel and titanium metal materials. There are advantages in that smooth sliding performance can be obtained, and there is little scratch damage and high-quality gloss with high durability can be obtained. However, since the ceramic material has a characteristic that it is difficult to perform post-processing after being molded and sintered, for example, it is not possible to perform caulking or the like normally used for metal materials, and a slide structure using the ceramic material. For this assembly structure, an improvement different from that of the metal material is required.

  By the way, as a conventional slide structure, for example, Patent Document 1 is a slide-type lock mechanism incorporated in a band fastener, and a pair of sliders are stacked inside a casing and slidably accommodated. A sliding structure is described.

The slide structure described in Patent Document 1 is based on the assumption that at least the casing is formed of a metal material. The casing is composed of two members, and a slider is accommodated in one half member and the other half member is formed. The assembly structure is such that they are brought into contact with each other and joined by caulking or the like.
