Abstract: A drive and control system for controlling the movement of a pool cover comprised of interconnected rigid buoyant slats. The system relies upon a hydraulic drive section including a hydraulic motor drive which may be initially provided with fluid under pressure by a remote electric drive section. The hydraulic drive section is also provided with an effective means of controlling movement of the pool cover, both in a winding direction on a cover drum, which may be submerged, and/or in an unwinding direction where the pool cover is being unwound from the drum. Various mechanisms to control the movement of the cover are described herein.

Abstract: An invented dual, coupled check valve mechanism is described for a direct drive, reversible hydraulic power source for hydraulic circuits that includes a manifold hydraulically coupled to the respective input/output ports and a reservoir of the hydraulic power source defining a translation passageway having mid-passage drain hydraulically coupled to the reservoir, where each end of the translation passageway has an angled annular valve seat opening to larger diameter plenum containing a check valve ball. A translating rod with a length greater and a circumferential diameter less than that of the translation passageway located in the translation passageway prevents the respective check valve balls from simultaneously seating on the valve seats at the respective ends of the translation passage way.

Abstract: An invented track construct component system with a threaded radial bearing end pulley is described for pool cover systems that includes an extruded longitudinal cover track having a top longitudinal anchoring slot, a C-channel longitudinal slot along one side edge for capturing and holding a side edge of a pool cover and associated sliders carrying a leading (front) edge structures, a cable return channel with a longitudinal slot opening along the other side edge for receiving and protecting cabling connecting between sliders/front cover comers and associated cable reels. Each cover track is secured within separate extruded side wall channel structures having a top channel side wall with a depending longitudinal shaped for snuggly fitting into the longitudinal anchoring slot of the cover track. The extruded side wall channel structures are incorporated into the side wall of the pool. A longitudinal spacer plate is inserted between the bottom channel side wall of the wall channel structure and the planar base face of the anchor track for mechanically holding the cover track within the wall channel with its anchoring slot snuggly receiving the depending longitudinal land of the wall channel. A similar extruded wall channel structure is incorporated into the end wall of the pool for accommodating an extending coupling plate-radial bearing end pulley assembly fastened at the distal end of the cover track. The radial bearing end pulley includes a novel inner annular race with an interior helical thread for screwing onto a perpendicularly extending, complementarily threaded, post integral with the coupling plate, and a rotating outer annular race with a concave exterior, circumferential groove for receiving, carrying and returning cabling connecting between a slider/front cover corner and a cable reel.

Abstract: The present invention is a modular lid system for an underwater swimming pool cover or other underwater enclosure. The modular lid has a rigid lid portion which has an overall buoyancy such that the lid portion closes the enclosure underwater by force of gravity. The modular lid system also has a remote power pack for providing a source of hydraulic power to the modular lid. The remote power pack is located at a position remote from the swimming pool. The remote power pack includes a hydraulic pump and a hydraulic drive mechanism is actuated by the remote power pack. The drive mechanism has a predetermined range of movement. A decoupled linkage mechanism extends between the hydraulic drive mechanism and the lid portion for causing limited opening movement thereof. The limited opening movement corresponds to the predetermined range of movement of the hydraulic drive mechanism. Thus, the decoupled linkage mechanism disengages from the lid portion during closing movement of the linkage mechanism and allows for manual opening movement of the lid portion beyond the limited opening movement caused by the linkage mechanism for increased access to the underwater enclosure.

Abstract: A manually powered swimming pool cover drive for extending and retracting swimming pool covers and which includes a pair of overrunning one way clutch devices for intermittent coupled rotation with and also freewheeling about a drive shaft. A drum rotates with the drive shaft and allows winding of a cover about the drum when retracted from a covered position over a swimming pool. A pair of one way clutches may be trained around a drive shaft and coupled for rotating a cable reel allowing for the winding of cables used to extend a swimming pool cover. The respective pairs of overrunning, one-way clutches are reciprocated back and forth respectively in a type of indexing operation, manually and with long lever handles for rotating the drive shafts.

Abstract: A track assembly for allowing movement of a flexible enclosure cover over an area to be enclosed as, for example, a body of water in a swimming pool. The assembly comprises a pair of spaced apart tracks mounted on opposite sides of the area to be enclosed with each being comprised of an elongate strip. Each track strip comprises a cable receiving channel with a gutter or debris trough located generally beneath the channel for collection of debris. Preferably, a slider can be located in the cable receiving channel for locking to the cable and for securement of the cover to the cable. The track can be constructed to also allow for lubrication of the cable receiving channel enabling a slider mechanism to freely move therein. When a slider is used, it extends into each channel at approximately a 45.degree. angle with respect to a vertical direction. In accordance with this construction, debris which might otherwise collect in the cable receiving channel will drop into the gutter and will not interfere with movement of the slider mechanism or the leading edge of the cover. The slider may be adjustably secured to a rigid body which is, in turn, secured to the leading edge of the cover, and which allows side-to-side adjustment of the leading edge. Adjustment in the 45.degree. angulated plane could reduce bending moment forces on the slider and track.
