Extendable/contractible frame cover for above-ground swimming pools

Abstract

A cover for an above-the-ground swimming pool includes a hard sloping frame for supporting the cover, with the frame being raisable and lowerable by hydraulic, electrical or piston mechanisms from inserted tubes within the spaced vertical struts which support the side walls of the pool in an original swimming pool manufacture or within adjacent struts additionally emplaced in the retrofitting of existing above-the-ground pools already in construction.

1 . A frame for supporting the cover of an above-ground swimming pool having a series of spaced verticals supporting the side walls of the pool, comprising:
 a plurality of tubular struts dimensioned to individually fit within or be secured to selected adjacent ones of said spaced verticals;   a series of spokes coupled with and upwardly slanting from said tubular struts to a central ring joining the spokes together;   a canopy of a mesh screen, plexiglass sheet or canvas layer between adjacent spokes of said series of spokes; and   means cooperating with said tubular struts in extending said struts upwardly and downwardly within the spaced verticals or adjacent thereto in the raising and lowering of the struts, the series of spokes coupled therewith, and the canopy with respect to a top railing of the above-ground pool.   
     
     
         2 . The frame of  claim 1  wherein the tubular struts are of a length of 4-5 feet. 
     
     
         3 . The frame of  claim 1  wherein the series of spokes upwardly slanting from said struts at a 2 inch per foot to a 5 inch per foot grade. 
     
     
         4 . The frame of  claim 1  wherein top ends of said spokes are connected with said central ring and bottom ends of said spokes are connected to top ends of said tubular struts. 
     
     
         5 . The frame of  claim 4 , also including a series of screen enclosures connected along a length of said spokes and downwardly unfurlable therefrom towards the top railing of the above-ground pool. 
     
     
         6 . The frame of  claim 1  wherein the tubular struts are of a length of 4-5 feet, wherein the series of spokes upwardly slanting from said struts at a 2 inch per foot to a 5 inch per foot grade, and wherein top ends of said spokes are connected with said central ring and bottom ends of said spokes are connected to top ends of said tubular struts. 
     
     
         7 . The frame of  claim 6  wherein the tubular struts are of a length of 4-5 feet, wherein the series of spokes upwardly slanting from said struts at a 2 inch per foot to a 5 inch per foot grade, and wherein top ends of said spokes are connected with said central ring and bottom ends of said spokes are connected to top ends of said tubular struts. 
     
     
         8 . The frame of  claim 4  wherein the tubular struts are inserted to individually fit within each of the series of spaced verticals. 
     
     
         9 . The frame of  claim 7  wherein the tubular struts are inserted to individually fit within each of the series of spaced verticals.
