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.
