本考案は板材によりコイルばねガイドを構成し、製造が
容易で廉価なコイルばね装置を提供しようととするもの
である。[Detailed Description of the Invention] The present invention aims to provide a coil spring device that is easy to manufacture and inexpensive, by constructing a coil spring guide using a plate material.
一般に機器において用いられるコイルばね装置は、その
コイルばねの全長が長い場合、圧縮時に座屈するため、
コイルばねにガイドな組合せる。Coil spring devices commonly used in equipment buckle when compressed if the coil spring has a long overall length.
Combined with a coil spring as a guide.

１の端部な固定する係止用突子４を設けていたものであ
る。Most of these are constructed as shown in Fig. 2, that is, they are combined with a pipe-shaped or cylindrical guide 2 that matches the inner diameter of the coil spring 1, and a flange 3 that serves as a stopper is attached to the upper part of the guide 2. Alternatively, a locking protrusion 4 for fixing the end of the coil spring 1 is provided.
このような構造のものは、ガイド２がパイプあるいは円
柱部材より形成されるため、材料費が高くなり、また、
７ランジ３および係止用突子４の加工がしにくい欠点が
ある。In such a structure, since the guide 2 is formed from a pipe or a cylindrical member, the material cost is high, and
7. There is a drawback that machining of the flange 3 and the locking protrusion 4 is difficult.
本考案は上記従来の欠点を解消するものであり、以下そ
の詳細を一実施例を示す第１図とともに説明する。The present invention solves the above-mentioned conventional drawbacks, and its details will be explained below with reference to FIG. 1 showing one embodiment.
本考案におけるガイド５は長尺状の板材を長手方向の基
線に沿ってＶ字状に折曲して形成される。The guide 5 in the present invention is formed by bending a long plate material into a V-shape along a longitudinal base line.
そして折曲辺ａ、ｂおよび稜辺Ｃに外接する外接円が、
コイルばね６の内径の円と同じかあるいはやや小さい形
状にしである。And the circumscribed circle that circumscribes the bending sides a, b and the edge C is
The shape is the same as or slightly smaller than the inner diameter of the coil spring 6.
また、ガイド５の上端には、一部を外方向に折曲してス
トッパー片７を形成してあり、上部端辺に、コイルばね
係止用の突子８を設げである。Further, at the upper end of the guide 5, a stopper piece 7 is formed by bending a part outward, and a protrusion 8 for locking the coil spring is provided at the upper end side.
なお、上記ガイド５はＶ字状以外にＵ字状、Ｗ字状、△
状、Ｎ字状等に折曲してもよく、以下のべる作用効果に
差異を生じない。In addition to the V-shape, the guide 5 has a U-shape, a W-shape, and a △
It may be bent into a shape, an N shape, etc., and there will be no difference in the following bending effect.

、廉価に製造できる。In the coil spring device of the present invention, a long plate material is bent along the longitudinal base line as described above, and the circumscribed circle circumscribing each bent side or the bent sides and the end sides is formed inside the coil spring. A guide of a suitable shape is formed and a coil spring is fitted to this guide.The guide member can be easily obtained by bending plate materials, and can be manufactured at a lower cost than conventional pipes or cylindrical members. .
また、ストッパーおよびコイルばね係止用の突子の形成
も簡単であり、その実用的効果の太きいものである。Further, the stopper and the protrusion for locking the coil spring are easily formed, and the practical effects thereof are great.
