The present invention relates generally to the field of covers or enclosures for pools, spas or hot tubs. More specifically, the present invention relates to an inflatable cover or enclosure having an inflatable body. The cover includes a side surface with an integrated retaining aid, a valve and an integrated pump. The cover or enclosure can be placed on top of a pool, hot tub or spa, or underneath an existing cover and can then be inflated to a shape such as a convex dome-like shape. Once inflated, the cover prevents debris or water from accumulating on the cover.

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 cover assembly for an indoor or outdoor item. The cover assembly is moveable between an expanded configuration and a collapsed configuration and includes panels of a textile material stitched together with inside seams and outside seams. The cover assembly receives the selected item within an interior area defined by the panels and the selected item holds the cover assembly in the expanded configuration. The outside seams are biased to close toward an interior area of the cover assembly and the inside seams are biased to close away from the interior area such that, when the cover assembly is removed from the selected item, the cover assembly is biased to close along the inside and outside seams to cause the cover assembly to move to the collapsed configuration to increase the ease of folding and storing the cover assembly.

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 device for covering a surface includes (a) a covering, each longitudinal edge of which is provided with a projecting element; (b) a rotatably mounted drum suitable for rolling up or unrolling the covering, and movable in translation on rails placed on either side of the surface; (c) a system for continuously locking/unlocking the projecting element in the rails during the translation of the drum. The projecting element includes a multitude of discreet elements distributed along each longitudinal edge separated from one another by an average distance (d).

Multilayer material may be made by applying bonding agent to a surface of a first-material and/or a second-material then bringing these materials adjacent to each other to bring the bonding agent into contact with opposing surfaces thereof and feeding the first-material and the second-material with the bonding agent therebetween into a machine to bond the first-material to the second-material to form the multilayer material. A cover for an object used outdoors may be made from a plurality of multilayer panels. A ventilation opening may be formed in a first multilayer panel, the ventilation opening may be covered with a ventilation cover, which may also be a handle, where the ventilation cover shields the ventilation opening from weather and defines walls of a passageway in an exterior space outside the cover, to provide for airflow through the ventilation opening between the exterior space and an interior space within the cover.

A reel for a swimming pool cover system includes an adjustable outer diameter that may receive a rope of the swimming pool cover system. The reel also includes an adjuster that may selectively change the outer diameter of the reel. A method for controlling an outer diameter of the reel includes controlling an adjuster of the reel such that the outer diameter of the reel changes.

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 drawbar assembly having a first continuous drawbar having an open end, a closed end, and an elongate body extending therebetween along an axis, and a spring anchor formed at the open end; a second continuous drawbar having an open end, a closed end, and an elongate body extending therebetween along the axis, and a spring anchor formed at the open end; the first and second drawbars oriented with respect to each other such that at least a portion of each elongate body overlaps with the other along the axis and the open end of one drawbar is proximate the closed end of the other; and a compression coil spring positioned over the overlapping elongate body portions and secured at each end by a respective spring anchor; wherein a region of at least one closed end is coined.
