Description
本発明は、ピン留め具に関する。
更に詳しくは、本発明は身体装飾品等に設けられたピンを留めるためのピン留め具に関する。本発明は、タイタック、ピンブローチ、ピアス、ネックレス等の装飾品のピン留めに適用されるが、装飾品以外の比較的小さなサイズの各種の物品のピン留めにも適用される。The present invention relates to a pin fastener.
More specifically, the present invention relates to a pin fastener for fastening a pin provided on a body ornament or the like. The present invention is applied to pinning ornaments such as tie tacks, pin broaches, earrings, necklaces, etc., but also to pinning various articles of relatively small size other than ornaments.
近年のピン留め具においてバネ材を使う構造が多い。しかし、小さいサイズである為に完全なフリーサイズ対応の金具は無く、部品の数も限られているため、大きいサイズと小さいサイズは無視されていた。
従来技術として、特許文献１に記載された金具を例示する
「特許文献１」特開２００８−３９４号公報
この金具は図示は省略するが、まず、ピン挿入用開口を有するハウジング内に内側壁面にテーパー部が掲載されている案内筒を設ける。そして、この案内筒の内側空間に、複数の球体と、該球体に対して下面が接触する顎部材を有し、かつ、弾性体により常にピン挿入用開口方向に付勢されている球体押圧部材が配置されている。その結果、テーパー部の所定の内径位置において、複数の球体で形成される環の内側においてピンを狭持するという構造である。ところが入れるピンの太さはさまざまである。細ければ抜けやすく、太ければロックの力が強くて解除が簡単にできない。Many pin fasteners in recent years use a spring material. However, since it is a small size, there is no metal fitting for completely free size, and the number of parts is limited, so the large size and the small size were ignored.
As a prior art, “Patent Document 1”, Japanese Patent Laid-Open No. 2008-394, which exemplifies the metal fitting described in Patent Document 1, although this illustration is omitted, first, an inner wall surface is provided in a housing having a pin insertion opening. A guide tube with a tapered portion is provided. And in this inner space of the guide cylinder, there are a plurality of spheres and a jaw member whose lower surface is in contact with the spheres, and a sphere pressing member that is always urged by the elastic body in the pin insertion opening direction. Is arranged. As a result, the pin is pinched inside the ring formed of a plurality of spheres at a predetermined inner diameter position of the tapered portion. However, the thickness of the pin to be inserted varies. If it is thin, it will be easy to remove, and if it is thick, it will have a strong locking force and cannot be released easily.
本発明は、ごく少数の部品でサイズの違うピンでも快適に安全にロック出来る金具を提供することを課題とする。It is an object of the present invention to provide a metal fitting that can be comfortably and safely locked even with pins of different sizes with very few parts.
ピンが挿入される筒体と、この筒体の外周に巻回されたコイルバネと、筒体及びコイルバネの外周を包囲する外筒体からなり、筒体には斜めにカーブ又は、多角した溝状又は窓状の切り込みを設けて、これにコイルバネの直線状の留め部を嵌合させることにより、この留め部と筒体の対向壁部との間にピン留め用の狭窄部を形成したことにより、太さの違うピンでも、ロックされる力が均一になり、細いピンは抜け落ちることもなく、太いピンはロックの解除が楽になって、安全な、快適なピン留め金具となった。いわゆる留め部と筒体の対向壁部との間にできる、ピン留め用の狭窄部の角度をピンの太さに応じて変えるのである。細いピンには狭窄部の角度を小さくして抜けにくくし、太いピンには狭窄部の角度を大きくしてロックの解除を柔らかくし形成することである。It consists of a cylindrical body into which a pin is inserted, a coil spring wound around the outer periphery of the cylindrical body, and an outer cylindrical body that surrounds the outer periphery of the cylindrical body and the coil spring. The cylindrical body has an obliquely curved or polygonal groove shape. Alternatively, by providing a window-shaped cut and fitting a linear retaining portion of the coil spring to this, a pinned narrow portion is formed between the retaining portion and the opposing wall portion of the cylindrical body. Even with pins of different thickness, the locking force became uniform, the thin pins did not fall out, and the thick pins became easier to unlock and became a safe and comfortable pin clamp. The angle of the pinned narrowing portion formed between the so-called fastening portion and the opposing wall portion of the cylindrical body is changed according to the thickness of the pin. For narrow pins, the angle of the stenosis is reduced to make it difficult to pull out, and for thick pins, the angle of the stenosis is increased to soften the release of the lock.
