ABSTRACT:
The protective covering for a marquee consists of a casing (22) carrying a winding shaft and having a discharge opening extending along the entire length of the casing, which can be closed tightly by a top flap (42) and a bottom flap (46). Top flap (42) is pivoted upward during the discharge of the marquee by its outer tube (14) counter to the force of gravity and following the re-entry of the marquee drops back into its closed position. Bottom flap (46) drops during the discharge of the marquee by its own specific gravity into open position and is drawn back into closed position at the end of the re-entry movement by means of closing levers (76) remaining in the movement path of the outer tube. The quite small top flap (42) cleans off the marquee, but loads it with only a slight weight. The pressure of the outer tube (14) against the closing levers (76) holds flaps (42, 46) dependably closed tightly in the re-entry position/closed position.
