  • Lift mechanism for a camper top
    Patent number: 3981529
    Abstract: A camper having a wheeled body and a top shiftable between collapsed and elevated positions relative to the body. A crank mechanism having a friction-held ratchet wheel is utilized to raise and lower the top between its extended and collapsed positions. In one direction of rotation of the crank mechanism the ratchet wheel is interlocked for rotation with the crank mechanism and in turn interlocks with a pawl to prevent reverse rotation of the crank mechanism as the top is raised. Reverse rotation of the crank mechanism releases the ratchet to permit movement of the lift mechanism relative to the ratchet wheel and a lowering of the top.
