Abstract: A light weight, durable, easily recyclable pool cover includes a fabric covering with reinforcing and attachment straps wherein, the reinforcing and attachment straps are attached to said fabric in a criss-crossed pattern. The fabric covering and the straps are produced from a single polymer consisting of polypropylene. The pool cover is entirely recyclable at end of service life by chopping the pool cover components in a simple machine producing granules useful for injection molding of polypropylene products. The pool cover fabric is produced by subjecting three layers of polypropylene sheet material to heat and pressure forming a strong durable fabric wherein the top layer and bottom layer are a solid fabric and the middle layer is multi-filament mesh of polypropylene threads.

Abstract: A flexible safety barrier edge material contacts a wall of a poolside raised obstacle with a hollow loop crossection. The loop portion is slit at multiple intervals to permit the individual sections to conform to relatively sharp inside or outside corner contours of the obstruction. A continuous stainless steel cable is guided around the respective portion of the pool cover periphery in the vicinity of the obstruction, by passing it through fabric webbing loops sewn at the edge of the pool cover. This cable is attached to a top surface of the pool wall deck using pool anchors with split loops having a cable receiving slot. The cable is looped thru said turnbuckle and secured via cable clamps and then tightened by the use of turnbuckles at either end of the cable.

Abstract: The installation and removal of a portable but sturdy pool barrier fence uses the hardware installed for attaching a safety pool cover during the pool use season. Multiple rectangular panel frames support a mesh fabric. Spaced anchors mounted in said deck adapted to support a cover or said fence when said cover is removed. The fence has rectangular sections formed by upper, lower and side frame members enclosing the fencing material. Each lower frame member in the fence sections has a centrally located rib extending longitudinally along a top surface thereof. Anchor clips, preferably Z-shaped clips, are located and attached to the deck at the anchors in the deck. Each of the anchor clips has a keyway for engaging a respective rib on the lower frame member of the rectangular fence section to secure the fence to the deck.

Abstract: A safety enclosure cover for a portable air-inflatable swimming pool includes a mat spread on a horizontal surface, with the inflatable pool resting on the mat. An outer rim of the mat extends beyond an outer wall of the inflatable pool. Water is filled into the inflatable pool so that an inflated holding pillow floats on an upper surface of said water. A cover encloses the inflatable pool and the floating holding pillow. An outer edge of the cover is attached to an outer edge of the mat whereby the water and inflatable pool are completely enclosed, so that the floating pillow pushes up on the inside of the cover, thereby the cover is formed into a convex shape so that rainwater is shed from the convexly-shaped cover.

Abstract: A swimming pool gap securement assembly prevents the accessibility of persons, animals or other objects into swimming pools, because of gaps left between the edges of a swimming pool cover and the surfaces of vertically rising decorative landscape obstructions associated therewith. The assembly provides one or more protective extensions of a swimming pool cover which covers any gaps present when a swimming pool cover encounters these vertically rising obstructions. These panels, one for each gap encountered, are generally of triangular shape, of the same fabric as the main pool cover or any other pool cover materials, and are sewn into, or otherwise attached to, the reinforced webbing at the edge of the pool cover. The lower horizontal edge and the vertical end edge of the wing extension panel have an attached edge strip with a linear array of holes engageable with one or more anchors imbedded into the deck or on the side of the obstruction itself.

Abstract: A zipper system for a safety swimming pool cover provides a convenient method of navigating around any vertical obstacles that may be within the pool cover area, when installing the pool cover over the pool. When a vertically extending obstacle, such as an entrance stair hand rail extends above the surface of a swimming pool cover, the swimming pool cover is split in the area of the obstacle, the zipper enables the user to securely navigate around the obstacle without compromising the tight fit of the swimming pool cover. The zipper closes the split area around the obstacle quickly and neatly. The zipper also prevents the entrance of debris into the pool around the split area. The zipper alternatively provides access to a selected area of the pool, such as a spa area. The spa area, when not in use, can be zipped and covered.

Abstract: A cover for a swimming pool includes a flexible sheet of material covering substantially all of an opening into the swimming pool. A split extends within the cover. Zipper elements line edges of the cover along the split to close the split, thereby preventing debris from entering the swimming pool through the split. A locking plate member covers top and bottom sides of the zipper to secure the zipper during the off-season. The locking member includes spaced apart upper and lower plates, forming a slot therebetween, whereby the slot provides clearance for fabric edges of the zipper. A bridge section joins the plates adjacent to a rear side of the locking plate member. A recess is formed in facing surfaces of the lower and upper plates between the bridge section and a front side of the locking plate member, to accommodate the zipper elements therein.

Abstract: The installation and removal of a portable but sturdy pool barrier fence uses the hardware installed for attaching a safety pool cover during the pool use season. Multiple rectangular panel frames support a mesh fabric. Each panel has a lower horizontal frame member with a series of slots accommodating the same fastener used to attach the pool cover coupling during the off-season. Sections of fencing panels are attached together using bi-fold hinges, which permit 360 degree rotation of one panel relative to an adjacent one. This allows storage of the barrier fence as a dense rectangular three dimensional unit by folding the panels upon each other accordion-like. Sections of fencing panels are joined together to form respective fence units to form the fence around the pool.

Abstract: An expandable socket holds a fence pole for a flexible swimming pool fence. The socket, being generally cylindrical, but slightly tapered, is open at a top end and has a bottom end partially closed with a rectangular opening. The socket sits within a bore within a concrete swimming pool deck or within a cylindrical sleeve adapted to be imbedded in a hole in earth. The lower end of the fence pole has a shaft, with a locking plate mounted thereon. The locking plate fits through the opening in the socket and is twisted to lock the pole in place within the socket. The socket has one or more lengthwise expansion ribs extending from a sidewall. Each rib is capable of limited pivotal outwardly and inwardly movement and has an increased taper at the distal end. When the fence pole is inserted into the socket, each rib is forced outwardly to engage an inner surface of the cylindrical sleeve.

Abstract: A solid mesh swimming pool cover incorporates a mesh layer that has been successfully used as a porous mesh cover for several years with a thin impermeable base layer. A two-step polymer coating process seals the mesh to produce a solid safety swimming pool cover of unusual light weight and durability with an abrasion resistant bottom layer that has a low coefficient of friction to facilitate easy removal. The base layer is a plastic or resin product, such as a co-polymer resin, and the top layer is a mesh pool cover fabric, such as polypropylene. Ultraviolet (UV) inhibitors added to both coating step materials insure an extended service life. Since the mesh used for the centrally located mesh panels in the drain type solid cover of this invention uses the same mesh as the rest of the non-porous cover, it is more aesthetically pleasing since it blends in with the rest of the cover.
