 Manual cover drive for swimming pools

Details
Inventors: Last, Harry J.;
Assignee:
Primary Examiner: Fetsuga; Robert M.
Assistant Examiner:
Attorney, Agent or Firm: Newhouse, Esq.; David E.

A manually powered swimming pool cover drive for extending and retracting swimming pool covers is described which includes a pair of overrunning, one-way clutch devices journaled around a drive shaft coupled for rotating a swimming pool cover drum for retracting a swimming pool cover and a pair of one-way clutch devices journaled around a drive shaft coupled for rotating a cable reel for extending a swimming pool cover. The respective pairs of overrunning, one-way clutch devices are reciprocated back and forth respectively, manually with long lever handles for rotating the respective drive shafts.

DETAILED DESCRIPTION I claim: 1.
A manual cover drive for winding a cover around a cover drum for retracting an extended cover comprising, in combination: a) a drive shaft coupled for rotating the cover drum in a winding direction to wind the cover around the cover drum, the cover drum being supported for rotation relative to a deck surface, b) a pair of overrunning, one way clutch mechanism overrunning around and engaging the drive shaft, oriented to engage the drive shaft when rotated in a winding direction, c) means for releasably coupling each overrunning, one way clutch mechanism to one end of a long lever handle, each long handle coupled to an overrunning, one way clutch mechanism journaled around the drive shaft having a length extending from the drive shaft providing sufficient mechanical advantage for winding the cover around the cover drum upon being reciprocated back and forth in a power and a return stroke responsive to human limb movement for rotating the drive shaft and the cover drum winding the cover around the cover drum retracting the extended cover.
2.
A manual cover drive for winding a cover around a cover drum for retracting a cover comprising, in combination: a) a drive shaft coupled for rotating the cover drum in a winding direction to wind the cover around the cover drum, the cover drum being supported for rotation relative to a deck surface, b) a part of long lever handles, each long lever handle having an overrunning, one way clutch mechanism on one distal end sized for slipping onto and off of the drive shaft, and for overrunning around and engaging for rotating the drive shaft, each long lever handle also having a length extending from the one way clutch mechanism at its distal end providing sufficient mechanical advantage for winding the cover around the cover drum upon being reciprocated back and forth in a power and a return stroke responsive to human limb movement when the one way clutch mechanisms at the distal ends of the pair of long lever handles are slipped onto for overrunning around and engaging for rotating the drive shaft
