【考案の詳細な説明】
この考案はコイル状に巻かれたバネ主体部と、
バネ主体部の両側方に係止部を有するコイルバネ
についての改良に関するものである。[Detailed explanation of the invention] This invention consists of a main body of a spring wound into a coil,
The present invention relates to an improvement in a coil spring having locking portions on both sides of a spring main body.
一般にコイルバネの係止部はバネ主体部から延
長されたバネ端子の先端をＵ字状に短く折り返す
ことで形成され、係止部を例えば、取付部材に貫
通させたり、あるいは取付部材に引掛けることで
係止されるようになつている。 Generally, the locking part of a coil spring is formed by folding back the tip of a spring terminal extending from the main body of the spring into a U-shape. It is designed to be locked in place.
したがつて、係止部の係止巾を越える板厚の取

とられているが作業が大変面倒となり作業性の面
で望ましくない。 Therefore, if the mounting member has a thickness that exceeds the locking width of the locking portion, there will be a problem that the mounting member cannot be locked. As a solution to this situation, measures have been taken, such as providing a separate mounting portion on the mounting member, but this is not desirable in terms of workability as it becomes very troublesome.

必要となるのでコイルバネの取付けスペースに機
能部品取付け用のスペースがプラスされる結果、
取付場所に制約を受ける等の問題を招来する。 Also, depending on the installation location, there are cases where additional functional parts are installed inside the coil spring, that is, between the coil spring and the mounting base.If it is not possible to secure a large installation space inside the coil spring, there are cases where functional parts are installed inside the coil spring. In some cases, there was a risk that the layout would be disrupted and design changes would be required. In particular, coil springs require space from the point where they are wound into a coil to the diameter of the coil, so as a result of adding space for installing functional parts to the installation space of the coil spring,
This leads to problems such as restrictions on the installation location.
そこで、この考案は比較的厚い板厚に設けられ

コイルバネを提供することを目的としている。 Therefore, this idea allows for reliable installation even with mounting holes made in relatively thick plates, allows for quick installation work, and allows installation in parallel with coil springs even when there are restrictions on the installation location. The purpose of the present invention is to provide a coil spring that can secure the space required for the purpose.

ている。 Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 5. Reference numeral 1 in the figure indicates the spring main body of the coil spring A. The spring main body 1 is formed by tightly winding a spring wire in a coil shape around the coil center line l, and is formed on both sides of the spring main body 1. are provided with locking portions 3 and 5. Of the locking portions 3 and 5 provided on both sides of the spring main body 1, one of the locking portions 3 has a tip end of a spring terminal portion 3a extending from the spring main body 1 along the coil center line l. It is formed by being folded inward in a short U-shape, and has a shape that faces into the extension area of the spring main body 1 approximately on the coil center line l. The other locking part 5 includes a first spring terminal part 5a extending away from the spring main body part 1 and in the direction of the coil center line l, as shown in FIG. a second spring terminal portion 5b that is bent and stretched in a substantially extending direction of the first spring terminal portion 5a at a position that substantially intersects the center line l;
consists of a third spring terminal portion 5c which is bent and stretched outside the extension area of the outer diameter of the coil, in a direction away from the spring main body 1, and approximately parallel to the coil center line l; A space S 1 of a predetermined width is secured between the extension region of the spring main body 1 and the spring main body 1 .
なお、バネ端子部５ｂの領域は、取付部材の板
厚とほぼ同一に設定されている。 Note that the area of the spring terminal portion 5b is set to be approximately the same as the plate thickness of the mounting member.

しい引張力が得られる。 In the coil spring A configured in this way,
For example, as shown in Figures 2 and 3, there is a mounting hole on one side.
When attaching to the brackets 9 and 7 having 1,
A case will be explained in which the plate thickness of the bracket 9 having the mounting hole 11 is relatively thick. The third spring terminal portion 5c side, which is one of the locking portions 5, is made to face the mounting hole 11. At this time, the spring main body 1 is placed at an angle θ with respect to the center line W of the bracket 9, and then the third spring terminal 5c is forcibly inserted into the mounting hole 11. After the insertion is completed, by pulling the other spring terminal 3a and hooking it onto the other bracket 7, the assembly can be completed quickly. When the assembly is completed, the third spring terminal portion 5c is in strong contact with the side surface of the bracket 9, and the bent portions of the first spring terminal portion 5a and the second spring terminal portion 5b are in strong contact with the edge of the mounting hole 11, so that the center of the coil is With respect to the front-back direction along line l,
Further, movement in the width direction perpendicular to the coil center line l is reliably regulated, and the locking portion 5 does not come off.
In addition, since the bent part of the first spring terminal part 5a and the second spring terminal part 5b, which is the tension point of the locking part 5, is located on the coil center line l, a correct tension force without deviation can be obtained. It will be done.
また、第３バネ端子部５ｃとバネ主体部１との
間に所定巾のスペース空間S1が確保される。 Further, a space S1 of a predetermined width is secured between the third spring terminal portion 5c and the spring main body portion 1.

As shown in FIG. 5, in the reclining device 13 equipped with
By locking the other locking portion 3 to the fixed bracket 19, a space S1 of a predetermined width is secured inside the spring main body portion 1. As a result, the actuation lever 21
layout can be done without any problems.
