ABSTRACT:
An improvement to ratchet wheels having a releasable pawl for engaging the ratchet wheel to prevent rotation thereof so as to allow release of the pawl from engagement with the ratchet wheel at a lower force. The pawl is in two parts hingedly joined together for movement between a locked position in an over-the-center state and a released position where the pawl is free to flex. A cam disc is operably connected to the pawl to move the pawl to the released position. In the absence of pressure from the cam disc, the pawl returns to the locked state from gravity and/or a spring member.
