A TORQUE-ADJUSTING DEVICE FOR USE IN A ROLLER BLIND |
摘要 |
A torque-adjusting device for twisting and untwisting a spring-motor built in a roller assembly is equipped with an easily operatable handle ring. The device includes a brake drum secured to a mounting bracket, a coil spring fitted on the brake drum, an intermediate disk disposed between the coil spring and the handle ring. The intermediate disk is integrally coupled with a stator to which one end of the spring-motor is fixed. The handle ring has an inner tongue inserted between the opposite projecting ends of the coil spring in a slit in the periphery of the disk with the result that the coil spring permits a rotational transmission from the handle ring to the stator but suppresses the counter transmission. |
