Abstract

A pool cover assembly for covering a swimming pool includes a cover, a pool cover box, and a reel positionable within the pool cover box and configured for carrying the cover. The reel includes a tube and an end piece. The tube includes an end with at least one keying feature and the end piece includes at least one mating keying feature. The keying feature and the mating keying feature coact to allow relative axial movement between the tube and the end piece, but not allow relative rotational movement between the tube and the end piece.

Claims

exact text as granted — not AI-modified
1 . A swimming pool, comprising:
 a plurality of side walls; and   a pool cover assembly for covering the swimming pool, said pool cover assembly including:
 a cover; 
 a pool cover box mounted along at least one of said side walls; and 
 a reel positioned within said pool cover box and carrying said cover, said reel including a tube and an end piece, said tube including an end with at least one keying feature and said end piece including at least one mating keying feature, said keying feature and said mating keying feature coacting to allow relative axial movement between said tube and said end piece, but not allow relative rotational movement between said tube and said end piece. 
   
   
   
       2 . The swimming pool of  claim 1 , wherein said end piece is a drive end piece, and further including an idler end piece, said tube including an idler end with at least one keying feature and said idler end piece including at least one mating keying feature, said keying feature of said idler end and said mating keying feature of said idler end piece coacting to allow relative axial movement between said tube and said idler end piece, but not allow relative rotational movement between said tube and said idler end piece. 
   
   
       3 . The swimming pool of  claim 1 , wherein said at least one keying feature in each of said drive end and said idler end are a plurality of recesses, and said at least one mating keying feature on each of said drive end piece and said idler end piece are a plurality of mating projections. 
   
   
       4 . The swimming pool of  claim 3 , wherein said plurality of recesses have a cross section with one of a circular, rectangular and square shape, and said plurality of projections have a mating cross section with one of a circular, rectangular and square shape. 
   
   
       5 . The swimming pool of  claim 1 , wherein each said keying feature is one of a recess and a projection, and each said mating keying feature is one of a mating recess and mating projection. 
   
   
       6 . The swimming pool of  claim 1 , wherein each said keying feature is a recess, and each said mating keying feature is a mating projection. 
   
   
       7 . The swimming pool of  claim 6 , wherein each said recess and each said mating projection have a cross section with one of a circular, rectangular and square shape. 
   
   
       8 . A pool cover assembly for covering a swimming pool, said pool cover assembly including:
 a cover;   a pool cover box; and   a reel positionable within said pool cover box and configured for carrying said cover, said reel including a tube and an end piece, said tube including an end with at least one keying feature and said end piece including at least one mating keying feature, said keying feature and said mating keying feature coacting to allow relative axial movement between said tube and said end piece, but not allow relative rotational movement between said tube and said end piece.   
   
   
       9 . The pool cover assembly of  claim 8 , wherein said end of said tube is one of a drive end and an idler end, and said end piece is one of a drive end piece and an idler end piece. 
   
   
       10 . The pool cover assembly of  claim 8 , wherein said at least one keying feature is a plurality of recesses, and said at least one mating keying feature is a plurality of mating projections. 
   
   
       11 . The pool cover assembly of  claim 10 , wherein said plurality of recesses have a cross section with one of a circular, rectangular and square shape, and said plurality of projections have a mating cross section with one of a circular, rectangular and square shape. 
   
   
       12 . The pool cover assembly of  claim 8 , wherein each said keying feature is one of a recess and a projection, and each said mating keying feature is one of a mating recess and mating projection. 
   
   
       13 . The pool cover assembly of  claim 8 , wherein each said keying feature is a recess, and each said mating keying feature is a mating projection. 
   
   
       14 . The pool cover assembly of  claim 13 , wherein each said recess and each said mating projection have a cross section with one of a circular, rectangular and square shape. 
   
   
       15 . A reel for use with a pool cover assembly, comprising:
 a tube and an end piece, said tube including an end with at least one keying feature and said end piece including at least one mating keying feature, said keying feature and said mating keying feature coacting to allow relative axial movement between said tube and said end piece, but not allow relative rotational movement between said tube and said end piece.   
   
   
       16 . The reel of  claim 15 , wherein said end of said tube is one of a drive end and an idler end, and said end piece is one of a drive end piece and an idler end piece. 
   
   
       17 . The reel of  claim 15 , wherein said at least one keying feature is a plurality of recesses, and said at least one mating keying feature is a plurality of mating projections. 
   
   
       18 . The reel of  claim 17 , wherein said plurality of recesses have a cross section with one of a circular, rectangular and square shape, and said plurality of projections have a mating cross section with one of a circular, rectangular and square shape. 
   
   
       19 . The reel of  claim 15 , wherein each said keying feature is one of a recess and a projection, and each said mating keying feature is one of a mating recess and mating projection. 
   
   
       20 . The reel of  claim 15 , wherein each said keying feature is a recess, and each said mating keying feature is a mating projection. 
   
   
       21 . The reel of  claim 20 , wherein each said recess and each said mating projection have a cross section with one of a circular, rectangular and square shape.
