Clutch Module For A Hoist Device And The Hoist Device Using The Same

A clutch module for the hoist devices comprising:

• A rotating body rotated by an external force;
• A first clutch member provided with a wrap spring integrally formed with the engaging portion;
• A clutch stator fixed to the bracket having a first spring frictional surface fitted to the first clutch member for providing a frictional force;
• A driving member including a first driving rotor for releasing the frictional braking force between the spring frictional surface of the clutch stator and the inner diameter of the wrap spring as the first clutch member, while rotated by rotation of the rotating body, by pushing the engaging portion of the first clutch member in the direction to be opened the body of the wrap spring as the first clutch member;
• A pickup member for increasing the frictional braking force between the clutch stator and the first clutch member by pushing the engaging portion of the first clutch member in the direction to be narrowed the wrap spring body of the first clutch member, while the rotational force of the driving member is transmitting to the power transmitting portion of the hoist device, conversely, the force is transmitted from the rotational force of the power transmitting portion of the hoist device;
• and
• An interference preventing means for preventing the phenomenon of decreasing the braking force due to the unnecessary interference between the driving member and the pickup member occurred while the rotational force of the power transmitting portion of the hoist device is transmitted to the pick-up member.
