Abstract: There is provided a retractable covering device comprising a sheet for covering an object comprising sleeves for receiving cords, a plurality of cords having proximal ends secured to spools and distal ends secured to the sheet, a retraction device that can use a clutching system having a rotating member for winding the cords onto spools to retract the sheet and unwinding the cords from the spools to extract the sheet, wherein at least two sleeves are oriented essentially longitudinally in a proximal portion of the sheet and essentially in a medial lateral orientation in a distal portion of the sheet to prevent a lateral accumulation of the sheet at the retraction device during retraction. The spools can be fitted with one or more tangle prevention members (spool covers) to prevent tangling of cords during use of the retraction device.
