A swim spa cover having a first bottom protection layer and may be positioned over the body of water. The first bottom protection layer includes a first radiant barrier. The swim spa cover includes a series of support rods that are adapted to engage across the first bottom protection layer. The swim spa cover includes a second rounded support layer positioned on top of the support rods. A third waterproof top layer is adapted to engage across the second rounded support layer. A first air gap is created between the body of water and first bottom protection layer. A second air gap is created between the series of support rods, the first bottom protection layer and the second rounded support layer. A third air gap is created within the second rounded support.

The present invention relates to a cover assembly including a frame including at least one inflatable portion. At least one cover is supported by the frame to define a chamber. Adjustment means is provided for adjusting the air conditions (e.g. pressure or oxygen content) of the pressure chamber.

A modular removable covering and barrier system. In one embodiment, a removable pool or pond covering system includes a track assembly installed on a deck along the perimeter of a pool, a sheet of plastic or other suitable material spanning the area enclosed by the track assembly, a bottom seal between the track assembly and the deck, and a top seal between the track system and the sheet of plastic. The track assembly may be modular such that the track assembly can be installed on any size and shape of pool or pond and can be easily stored when not in use.

A pool cover assembly includes a first encapsulation member defining a first side of a pool cover encapsulation, the first encapsulation member comprising a first mating feature. The pool cover assembly further includes a second encapsulation member defining a second side of the pool cover encapsulation, the second encapsulation member comprising a second mating feature. And the pool cover assembly further includes a corner endcap member comprising a third mating feature and a fourth mating feature. The first encapsulation member is coupleable to the corner endcap by the first mating feature and the third mating feature, and the second encapsulation member is coupleable to the corner endcap by the second mating feature and the fourth mating feature. The corner endcap member couples with the first encapsulation member and the second encapsulation member to form a corner of the pool cover encapsulation.

A swimming pool cover assembly including a frame, at least one cover, and an adjustment means. The frame including at least one inflatable portion and an interconnected three-dimensional (3D) lattice of inflatable straight tubes. The at least one cover is supported by the frame to define an exercise chamber including at least part of a swimming pool. The adjustment means reduces an oxygen content of air in the exercise chamber compared with air external the exercise chamber. The exercise chamber has elongate sidewalls.

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.

A dome shaped roof structure for outdoor pools, both above ground pools and with minimal modification inground pools, that does not interfere with the use of the pool consisting of a plurality of flexibility poles supported by the pool, with a flexible tension ring holding the pole ends together over the center of the pool and a net fabric material that covers the pole and tension ring frame which is secured around the top of the pool. The roof structure works for all shapes and many sizes of pools providing protection from bugs and debris while still maintaining the outdoor experience. The high flexibility of the frame and tension ring allows winds and rain to flow thru without damage to the roof during inclement weather. The low number of elements that make up the roof structure make it inexpensive as well as easy to assemble, dismantle and store.

A cover for a hot tub or spa is disclosed having a flat cross beam positioned across on a first axis of the tub, the flat cross beam having first and second ends, and being configured to support an interior cover, a curved joist disposed above the flat cross beam, and arranged in substantially the same plane as the cross beam, and pivotably connected to the flat cross beam at respective first and second ends, the curved joists being configured to support an exterior cover, a vertical connector engaged to the flat cross beam on one end and engaged to the curved joist on a second end, wherein upon applied motive force in a direction, the vertical connector is configured to collapse and flatten the exterior cover. A method of using the same is also disclosed.

A pool cover assembly includes a first encapsulation member defining a first side of a pool cover encapsulation, the first encapsulation member comprising a first mating feature. The pool cover assembly further includes a second encapsulation member defining a second side of the pool cover encapsulation, the second encapsulation member comprising a second mating feature. And the pool cover assembly further includes a corner endcap member comprising a third mating feature and a fourth mating feature. The first encapsulation member is coupleable to the corner endcap by the first mating feature and the third mating feature, and the second encapsulation member is coupleable to the corner endcap by the second mating feature and the fourth mating feature. The corner endcap member couples with the first encapsulation member and the second encapsulation member to form a corner of the pool cover encapsulation.

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.
