An assembly includes an inflatable, dome-like cover that is configured to rest atop an existing swimming pool. The cover has an inflatable portion that repels dirt, debris, water, and snow, preventing such debris from collecting thereon. The cover is produced from heavy duty, yet lightweight plastic or rubber material. The cover may sized and configured to fit a pool of any dimensions. Extending along a perimeter of the inflatable portion is a border about which openings are evenly spaced, through which tethers or cords may be tied for securing the assembly to the pool. At least one air valve is positioned proximal to the outer edge of the cover, enabling a user to inflate the assembly.

A roll-up spa cover for protecting and insulating an outdoor swim spa includes a multi-layer flexible insulation sheet structure is sized to at least cover a top of a spa and comprises at least two flexible layers. Support members may be attached to the plurality of support members in a parallel spaced relationship. Flexible rods can be removable located onto or into the support members to form an arcing framework over the support members. A rain fly may be overlaid on the flexible rods. The support members may include an angled aperture for receiving an end of the flexible rods and end caps may be provided over ends of the support members. The flexible rods are held in compression between the angled apertures and/or the end caps.

An inflatable pool cover assembly includes a top disk that is positionable in a pool and float on water in the pool. A bottom disk is positionable in the pool and float on the water in the pool. A bladder is positioned between the top disk and the bottom disk and the bladder is inflatable to a selected diameter. The bladder is inflated to engage an inside surface of a perimeter wall of the pool thereby covering the water in the pool. A plurality of engaging members is each coupled to the bladder and each of the engaging members releasably engages the perimeter wall of the pool. An inflation unit is coupled to the top disk and the inflation unit is in fluid communication with the bladder. A cartridge is provided that is filled with a compressed gas. The cartridge is fluidly coupled to the inflation unit thereby facilitating the compressed gas to exit the cartridge and inflate the bladder.

An inflatable spa liner to be placed in a tub or spa pedicure bucket to prevent a user from contacting the surface of the tub is disclosed. The inflatable spa liner includes a first layer and a second layer that are sandwiched. The inflatable spa liner includes air channels formed at one of the first layer and the second layer. The air channels are arranged in between the first layer and the second layer. The inflatable spa liner is placed in a tub such that the first layer is in contact with the surface of the tub. The air channels inflate such that a user sitting in said inflatable spa liner contacting said second layer does not come in contact with the surface of said tub.

A thermal insulation structure for liquid enclosures (4) is provided. The thermal insulation structure improves the liquid enclosure's thermal insulation thereby requiring less work by external components to maintain the temperature within the liquid enclosure (4). The thermal insulation structure includes a cover (10) and/or a plug (3). Both the cover (10) and the plug (3) each include a plurality of layers, which contribute to their insulating properties.

The present invention includes an inflatable spa pool with thermal insulative properties to maintain an elevated temperature of water stored in the spa pool. The inflatable spa pool can include a pool body including a wall and a bottom, where the wall includes an inner wall and an outer wall, where the inner wall and the bottom define a cavity with a first upper opening. The inflatable spa pool can include a thermal insulation pool sheath with a second upper opening to receive the pool body, where the thermal insulation pool sheath includes an outer sheath and a first thermal insulation structure. The inflatable spa pool can include a thermal insulation pool lid that includes an outer lid and a second thermal insulation structure, where the bottom includes an upper layer and a lower layer for receiving a third thermal insulation structure.

The present invention discloses a pool apparatus for a variety of recreational purposes. The pool apparatus includes a first tank having a first base, and a tapered section extending away from the first base. The tapered section includes holes. The pool apparatus includes a second tank having a second base and a cylindrical section extending from the second base. The first tank positions in the second tank such that the first base aligns the said second base. The cylindrical section includes pipe receiving sections. The pool apparatus includes pipes connecting the holes and are drawn through the pipe receiving sections. The pipes circulate water for filtration purposes in a closed loop system into the first tank. The second tank presents an air gap with the first tank and allows the first tank to keep cool water cool and warm water hot. The pool apparatus includes a cover at the top.

In one preferred form there is provide a pool cover arrangement (10) comprising: a body (12) having a first set of cells (24) and a second set of cells (26). The first set of cells (24) provide a first area (35) for floating on water. The first area (35) comprises the forward facing areas (27) of the first set of cells (24). The second set of cells (26) are spaced away from the forward facing areas (27), so as to sit above the water, when the first set of cells (24) sit on the water. In other preferred forms ventilation holes and layers are provided.

A spa cover constructed of layers of pliable insulation encapsulated within a weatherproof vinyl reinforced fabric or a rubber membrane which is attached to rigid square support tubes that run parallel to the short end of the spa. The encapsulated insulation is fastened to the bottom of the square support tubes with corrosion-free nylon anchors which allows the soft insulation assembly to span over the water and rest directly on the spa bartop surface sealing the heat in and keeping debris out. An arched fiberglass rod structure supports a weatherproof rainfly which is permanently affixed to the flat cover assembly to shed rain and debris. The entire assembly is held in place at each end with adjustable straps which stretch the cover from end to end keeping the rainfly taut. Removing the cover to access the spa involves undoing the straps on one end and rolling the cover assembly towards the other end until the desired amount of spa exposure is reached. Covering the spa after use is just the opposite procedure.
