Abstract:
A protective covering device for covering a physical object positioned on a planar surface comprising:a. a weather resistant, flexible sheet material of suitable dimension to cover a physical object, the flexible material having a leading edge, an inner surface adapted to face the object to be covered and an outer surface adapted to face away from the object to be covered,b. a reverse rotation biased roller adapted for positioning adjacent a location of the physical object to be covered and upon which the flexible material is stored,c. means to progressively extend a portion of the flexible material from a stored position upon the roller to intermediate positions, including partially covering the object, to a substantially fully covered position,d. shaping means positioned along the side edges of the weather resistant sheet material,e. the flexible sheet material and shaping means along the side edges of the sheet material being of a suitable, composition and form and the reverse bias of the roller as well as the trajectory of the means to progressively extend a portion of the flexible material being such that the force required to extend the flexible material from the stored position on the roller to the intermediate positions at least partially off the roller is greater than the force required to extend the flexible material from the intermediate positions to the covered position of the obiect as a result of air captured under the inner surface of the flexible material during the extension of the flexible material from the intermediate positions to the covered position, such air creating a parachute-like effect upon the flexible material.
