Abstract

PURPOSE:To make a cord reel compact, by providing the main rotary shaft of the cord reel with a stopper function to maintain a power cord in a pulled-out position. CONSTITUTION:To maintain a power cord 20 in a pulled-out position, the cord pulling-out force is eliminated, a reel 25 supported on a main shaft 23 of small diameter is made eccentric outwards from the axis of the main shaft, by a spiral spring 21, and a stopper 26 made of a material of high friction coefficient and provided on the periphery of the reel is pushed on the inside wall of a cose 24 so that the force of the spiral spring acting to wind the power cord is canceled by the frictional force between the stopper and the case. To wind the cord 20, the main shaft 23 is slid in the axial direction by an external force, the eccentricity of the reel 25 is eliminated, and the stopper 26 is separated from the inside wall of the case 24 so that the force of the helical spring 22 returns the cord into the case.

A reel 5 for winding the power cord 4, cases 6 and 7 for supporting the rotation of the power cord 4, a spring 8, and a spring 8 for preventing rotation of the ratchet portion 2 due to unwinding of the mainspring. Moreover, it generally has a pawl 9 that slides in the axial direction of the reel 5 and can be easily returned by the spring 8, and the case 7 is provided with a contact brush 10. However, this configuration had the following problems.

In order to achieve smooth rotation and sliding, the main shaft has a shaft diameter that forms an excessively large gap with the rotating and sliding part of the reel, and is capable of sliding movement in the axial direction. a coil spring that returns the sliding movement after the external force is released;
and a case that encloses the reel and supports sliding movement in the axial direction of the main shaft, and has a stop i4- made of a material with a large coefficient of friction on the outer circumference of the reel, so that the power cord can be pulled out. If you want to hold the cord in that position, release the cord pulling force, and the reel supported by the small diameter main shaft will be eccentric from the main shaft axis due to the mainspring, and the stopper made of a material with a high friction coefficient will press against the inner wall of the case. It is possible to stop by being stopped. In addition, if you want to rewind the power cord, you can use external force to slide the main shaft in the direction of the shaft center, which eliminates the eccentricity of the reel and moves it away from the inner wall of the main shaft and hook, making it possible to unwind it by the force of the mainspring. becomes.
