A spa pool cover lifter and a spa pool including a spa pool cover lifter are disclosed. The spa pool cover lifter may include a first arm pivotally attached to a first section of an articulated spa pool cover and a second arm pivotally attached to a second section of the articulated spa pool cover. The first and second arms may be configured such that rotation of the first arm causes the first and second sections of the spa pool cover to fold together. An actuator and controller is disclosed. A mechanical linkage between the actuator and first arm is disclosed. The mechanical linkage may be an over-rotation linkage.

A diving pool includes a first tiered section extending to a first depth of the diving pool, a second tiered section extending to a second depth of the diving pool that is deeper than the first depth, and a cover. The cover can be releasably positioned within the diving pool at a depth of the diving pool to isolate a shallower portion of the diving pool above the cover at the depth from a deeper portion of the diving pool below the cover at the depth.

A protective sleeve is disclosed herein consisting of a rectangular upper and lower panel with three edges of the panels permanently sealed together and at least one shorter edge unsealed to allow for full insertion and extraction by one person a swimming pool cover hold-down weight water tube and allows for airtight or non-airtight sealing of the unsealed end.

A latch system that attaches to a retractable load bearing pool cover. The latch system interconnects deployable and retractable load-bearing floor panels or pool cover panels that may be separable into individual sections for compact vertical stacking and storage when the panels are retracted.

A movement assistance device for a spa cover having at least two spa cover portions each spa cover portion having opposing lateral peripheral edges, hinge and end peripheral edges and wherein the spa cover portions are movable one relative to the other from a first coplanar orientation to a second, stacked orientation, and a biasing pneumatic cylinder which cooperates with and extends between a first bracket secured to one lateral peripheral edge of one spa cover portion and a hinge bracket secured to the same lateral peripheral edge of the same spa cover portion adjacent the hinge peripheral edge and the hinge bracket is further secured to an aligned lateral peripheral edge of a second spa cover portion and adjacent to the hinge peripheral edge thereof, and wherein the pneumatic cylinder assists and controls the movement one spa cover portion relative to the other spa cover portion.

A diving pool includes a first tiered section extending to a first depth of the diving pool, a second tiered section extending to a second depth of the diving pool that is deeper than the first depth. The diving pool may be configured to facilitate pressure-based therapeutic treatments at the various depths. The diving pool may include a cover. The cover can be releasably positioned within the diving pool at a depth of the diving pool to isolate a shallower portion of the diving pool above the cover at the depth from a deeper portion of the diving pool below the cover at the depth.

A lift assembly for a spa cover includes a lifting arm having a first end pivotally connectable to the spa cover and a second end pivotally connectable to a base of a spa, the connection of the second end of the lifting arm with the spa housing defining a pivot point, and a lift-assist device having a first end configured for coupling to the base at a point substantially directly below the pivot point and a second end operatively connectable to the lifting arm. The lift-assist device is configured to exert a generally upwards biasing force on the cover when the cover is received atop said spa.

Solar panels located on residential roofs can be unsightly in some cases. A swimming pool solar power generator can locate solar panels in or around the sides and/or bottoms of a swimming pool in a manner so as to create electricity from the sun without creating an eyesore. In an embodiment, a pool solar power generator includes a solar cell module disposed in a portion of a swimming pool. The solar cell module can include solar cells and be submerged under water held by the swimming pool. The solar cell module can convert sunlight incident on the solar cells to electricity and transmit the electricity for use at a location external to the swimming pool.
