Abstract

PURPOSE:To obtain a cheap cord wind-up device having a small number of component parts by providing a support means for supporting a reel, rotatably and movably in the diametrical direction of the reel. CONSTITUTION:When a cord 9 is wound up, a clamp means is released so that the cord 9 is wound up onto a reel due to energy stored in a spring 13. At this time, the reel 10 is rotated. Even though the reel 10 is manufacture with a high degree of accuracy, the cord wound on the reel 10 causes rotational unbalance. The bore of a shaft insertion hole in the reel 10 is greater than the diameters of shafts 11, 12, the reel 10 carries out eccentric motion. Then, outer peripheral surface of the reel 10 abuts against the inner peripheral surface of the reel 10, and accordingly, the rotation of the reel 10 is braked. The braking force increased as the rotational speed of the reel increases while it decreases as the rotational speed decreases.

It is. The difference between the diameters of the shafts 11 and 12 and the inner diameter of the shaft insertion hole of the reel 10 is D2. The relationship between dimensions D1 and D2 is Di<D2. 13 is a winding spring, one end is fixed to the case 8, and the other end is a beam.
It is stopped at Le 10.

When winding up the cord 9 after using an electrical device, the seven winding springs 6 release the clamping means.
Code 9 becomes reel 10 due to the energy stored in
It is wound up. At this time, the reel 10 rotates. Even if the reel 10 is made with good precision, the rotational balance of the reel 10 is off due to the winding of the cord 9. Also, the diameter of the shaft 11, 12
3~ Since the inner diameter of the shaft insertion hole of the reel 10 is larger, the reel 10 moves eccentrically. Then, the outer peripheral surface of the reel 10 comes into contact with the inner peripheral surface of the case 8, and the rotation of the reel 10 is braked. This braking force increases as the rotational speed of the reel 1o increases, and weakens as the rotational speed of the reel 10 decreases.

As described in detail, the cord winding device of the present invention is provided with a support means that supports the reel so that it can rotate freely and can move in the radial direction of the reel by an amount greater than the distance between the inner surface of the case and the outer periphery of the reel. Therefore, the speed at which the reel winds the cord can be adjusted appropriately without using any special parts for controlling the rotation of the reel. Therefore, it can be manufactured at a lower cost than the conventional one which includes parts for controlling the rotation of the reel.
