Abstract
A self-locking clutch mechanism comprising a base, an output member journalled to the base, a first spring engaged between the base and the output member, the first spring exerting a first spring force in a first direction, a clutch spring engaged with an intermediate member and frictionally engaged with a base cylindrical surface, an input member rotationally engaged with the base, the input member intermittently engagable with the clutch spring through a control member such that the clutch spring is temporarily released from the base cylindrical surface upon a rotary movement of the control member in a first direction, the intermediate member rotates upon release of the clutch spring from the base cylindrical surface, and a second spring engaged between the intermediate member and the output member, the second spring exerting a second spring force opposite the first spring force.
