A keychain is sometimes used for the key to prevent the key from being lost and to improve usability.
Nowadays, there are various types of keychains with fashionability in mind, such as mascots, wallets, etc. However, such keychains are bulky and may be inconvenient to carry. A simple key holder is a ring-shaped key holder made of piano wire spirally wound at least once or usually twice. This uses a steel wire (piano wire) with a certain elasticity, so when inserting the key into the key chain or removing it, it is necessary to apply a force that exceeds the elasticity of the steel wire. When external force is applied, the elasticity of the piano wire is lost and it no longer returns to its original state.
本考案はこれに鑑みて、キーを簡易にキーホル
ダーに取り付け、取り外しが行え、しかも大きな
外力を加えても確実に復元するようになした簡便
なキーホルダーの提供を目的とする。 In view of this, it is an object of the present invention to provide a simple key chain in which a key can be easily attached to and removed from the key chain, and which can be reliably restored even when a large external force is applied.

Using an elastic alloy wire with shape memory properties, it is formed into a loop shape so that it can be kept at room temperature, and one end of the wire is fitted and fixed inside a pipe-shaped fitting, and the other end is inserted into the fitting. It can be removably inserted into the fitting hole.

A simple key chain is formed into a loop shape using an elastic alloy with shape memory properties, one end of which is fitted and fixed to a pipe-shaped fitting, and the other end is detachably fitted and locked to the fitting. Because it is shaped like this, it is easy to attach and detach the key to the key chain, and even when a large external force is applied to the key chain, the elastic properties are not impaired, making it easy to use.
次に本考案キーホルダーを図示の実施例にもと
づいて説明する。
Next, the key chain of the present invention will be explained based on the illustrated embodiment.
第１図は本考案キーホルダーにキーを装着した
状態を示す。 FIG. 1 shows a state in which a key is attached to the key chain of the present invention.
図において、１は形状記憶特性を備えた弾性合
金の線材をもつてループ状に形成したるキーホル
ダーで、この弾性合金としてNiTi合金を用い、
このNiTi合金を主体とし、キーホルダーとして

（Ｘ＝Si，So，Ａ□×など），Cu−Ａ□×−Ni，Au−
Cd，Ag−Cd，Ni−Ａ□×，Cu−Au−Zo，Cu−Soな
どを必要に応じ適量加えるものとする。 In the figure, 1 is a key chain formed into a loop shape with a wire made of an elastic alloy with shape memory properties, and NiTi alloy is used as the elastic alloy.
Based on this NiTi alloy, C u −Z o , C u −Z o −X
(X=S i , So , A□×, etc.), C u −A□×−Ni, A u −
Appropriate amounts of C d , A g −C d , Ni−A□×, C u −A u −Z o , C u −S o , etc. are added as necessary.
このようにして所要の弾性及び線径を有する線
材を用い、キーホルダーに適したループ状に屈曲
し、その両端部を互いに突き合わせるようにす
る。このときキーホルダー使用環境の常温では定
形状を保持するように加工する。 In this way, a wire having the required elasticity and wire diameter is bent into a loop shape suitable for a key chain, and both ends of the wire are butted against each other. At this time, the key chain is processed so that it maintains its regular shape at room temperature in the environment in which it is used.
そしてこの線材の一端にパイプ状で他の金属あ
るいは合成樹脂にて形成したる継金具２を嵌着す
る。これは線材の一端を継金具１の孔２２内に嵌
合し、その外周を圧着して固定し、他端を自由端
とする。そしてこの自由端１１を嵌合する継金具
２の孔２１は自由端１１の線径より若干大径とな
す。 Then, a pipe-shaped joint fitting 2 made of another metal or synthetic resin is fitted to one end of this wire. In this case, one end of the wire is fitted into the hole 22 of the fitting 1, the outer periphery of the wire is crimped and fixed, and the other end is left free. The hole 21 of the fitting 2 into which the free end 11 is fitted has a diameter slightly larger than the wire diameter of the free end 11.
従つて、第１図の鎖線で示したように自由端１
１を継金具２の孔２１より抜いて、この自由端側

この状態を第２図に示す。 Therefore, as shown by the chain line in FIG.
1 from the hole 21 of the fitting 2, and insert the key K from this free end side. After that, when the external force applied to the free end 11 is released, the wire returns to its original position due to its elasticity, and the free end 11 is fitted into the hole 21.
This state is shown in FIG.
また第３図に示すものは異なりたる実施例で、
継金具２を省き、線材をもつて少なくとも１回以
上螺旋状に巻回したものである。 Moreover, what is shown in FIG. 3 is a different embodiment,
The fitting 2 is omitted, and the wire is wound spirally at least once.
