The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

An insulated spa cover (10) contains a thermal insulating core (30), a top cover (150) with an average permeance of at least 57.2 nanograms/Pascal*seconds*square meters, and a hydrostatic head test value of at least 5,000 Pascals, a vapor barrier (130) and optionally a bottom sheet (140) apart from the vapor barrier. Venting pathways are defined around the thermally insulating core to facilitate escape of water vapor.

An above-ground swimming pool with integral automatic raising and lowering hard cover, and an automatic raising and lowering retrofit hard cover for an existing in-ground and above-ground swimming pool. The raising and lowering of the hard cover takes place with the utilization of two or more linear actuators that are telescopic or non-telescopic and actuated through the use of mechanical (screw jack, rack and pinion or pulley types), hydraulic (piston type), pneumatic (piston type), electro-mechanical, Piezoelectric and linear motor devices. The hard cover provides several benefits to the user of the pool.

A spa cover lifting system is provided for selectively removing and replacing the cover of a spa. The spa cover lifter system has a frame configured to hold a cover of the spa and an actuator coupled to the frame. Selective actuation of the actuator by a user causes at least a portion of the frame and the cover to rotate about and between a first, closed position, in which access to the water of the spa is restricted, and a second, open position, in which access to the water of the spa is not restricted. The actuator and at least a portion of the frame are positioned below a deck that is around the outside of the spa so that the actuator and at least a portion of the frame are inaccessible to a user of the spa during normal usage.

A manual or motor activated enclosure, appropriate for any surface to be enclosed, comprising matching opposite cross-linked structures containing a set of profiles that fits in the field of telescopic modular pivoting roof structures, that upon retraction it is housed underground such that none of its components are visible above ground, and upon deployment it achieves complete enclosure of the area while proving for openings.

The present invention is directed to a plate settler cover that prevents algae growth, prevents contamination from organic material, and provides structural support for a user who is standing or walking on the plate settler system. The plate settler covers can either float directly on standing water present in the system or may be structurally supported such that the plate cover is positioned above the surface of the water.

A lift system for a spa cover includes a first lift assembly configured for coupling to a first side of a spa, the first lift assembly including a motor and a first lever arm, the first lever arm having a first end configured for driving connection to the motor, and a second end configured for operative connection to a spa cover, and a clutch assembly configured to transmit torque from the motor to the first lever arm, the clutch assembly including a drive plate rotatably driven by the motor, a clutch plate arranged parallel to the drive plate, and a plurality of projections extending from one of the drive plate and the clutch plate and being configured to engage a corresponding plurality of recesses in the other of the drive plate and the clutch plate.

A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.
