本考案は内燃機関用のリコイルスタータにおけ
るリールのロープ収納溝に関するものである。[Detailed Description of the Invention] The present invention relates to a rope storage groove of a reel in a recoil starter for an internal combustion engine.
従来のこの種ロープ収納溝には第１図に示すよ
うに、リール１の外周から内方へロープ２が１列
に巻かれるように溝３を深く設けたもの。また、
第２図に示すように２列に巻かれるように横幅を
広くした溝４を設けたものがある。 As shown in FIG. 1, the conventional rope storage groove of this type has a deep groove 3 so that the rope 2 is wound in a row from the outer periphery of the reel 1 inward. Also,
As shown in FIG. 2, there is one in which a groove 4 with a wide width is provided so that the winding can be wound in two rows.
然し、リコイルスタータでエンジンを始動する
場合、その性能と操作性の良否はロープを引張る
ときの張力とリールの回転スピードによつて左右
される。この関係を第３図により説明る。 However, when starting an engine with a recoil starter, its performance and operability depend on the tension when pulling the rope and the rotational speed of the reel. This relationship will be explained with reference to FIG.
先ず、ロープの引張り速度を一定とし、横幅に

列巻きの方が有利であるという二律背反の関係に
ある。 First, the pulling speed of the rope is set constant, the width is the length of the rope, and the vertical axis is the rope tension and the rotation speed of the reel. Then, the rotational speed of the reel decreases faster when the diameter of the rope wound in the reel groove is wound in one row, and thus reaches a high rotational speed faster than when wound in two rows. Therefore, when the characteristics are shown in FIG. 3, the case of one row of winding is represented by straight line A, and the case of two rows of winding is represented by straight line A2 . Next, the tension in the rope becomes higher in single-row winding, where the winding diameter of the rope decreases faster due to inertial resistance on the engine side. Therefore, the characteristic curve can be expressed as the third
As shown in the figure, the case of one row of winding is the B1 curve, and the case of two rows of winding is the B2 curve. For these reasons, single-row winding is advantageous in obtaining a high starting rotation speed.
On the other hand, in order to obtain low rope tension from the viewpoint of operability, 2
There is a trade-off relationship in which row winding is more advantageous.
言いかければ、１列巻きでロープ張力を下げる
にはリールの径を大きくしなければならないが、
そうするとリールの回転スピードが下がつてしま
う。反対に２列巻きでリールの回転スピードを上
げるにはリール径を小さくしなければならない
が、そうするとロープ張力が上がつてしまうとい
う欠点があつた。 In other words, in order to reduce the rope tension by winding in one row, the diameter of the reel must be increased,
This will slow down the rotation speed of the reels. On the other hand, in order to increase the rotational speed of the reel with two rows of winding, the reel diameter must be made smaller, but this had the disadvantage that the rope tension would increase.

したものである。以下本考案の一実施例を図面に
より詳細に説明する。 The present invention aims to eliminate these conventional drawbacks and improve the performance and operability of the recoil starter. An embodiment of the present invention will be described in detail below with reference to the drawings.
第４図は本考案リールのロープ収納溝の縦断面
図で、図に示すように、ロープ２を収納するリー
ル１の溝幅を外周部分ではロープ２が２列に巻け

る。 FIG. 4 is a vertical cross-sectional view of the rope storage groove of the reel of the present invention. As shown in the figure, the width of the groove of the reel 1 that stores the rope 2 is set so that the rope 2 can be wound in two rows at the outer circumferential portion, and at the other end. One of the two rows is provided with grooves 5 that are one row wide and deepen inward.
次に、このような構成の特性について述べる。 Next, the characteristics of such a configuration will be described.
先ず、第３図と同じように、ロープ引張り速度

要なリール回転スピードが得られる。 First, as in Fig. 3, the rope pulling speed is kept constant, and the horizontal axis is the rope pulling length,
The rope tension and reel rotation speed are plotted on the vertical axis. Then, a characteristic curve as shown in FIG. 5 is obtained.
That is, as shown in the A3 curve in Figure 5, the rotational speed of the present invention is such that the rope winding diameter of the reel is large in the part to the left of point P where the inertial resistance of the engine is high, and the rope tension is low due to the two-row winding. It is held low. Then, in the part to the right of point P where the engine starts to rotate and the inertial resistance becomes low, the reel rope winding diameter becomes smaller, and the necessary reel rotational speed is obtained because of single row winding.

ある。 As described above in detail, the present invention has the effect of rationally improving both the performance and operability of the recoil starter with a simple configuration.
