Abstract: A retractable cover for protecting designated area and spaces. A stationary rigid portion receives telescopically extending portions movable over guiding assemblies to house vehicles and other objects and protect them. When the telescopic rigid portions are fully extended, they engage and interlock with seals resulting in a water tight structure. Also, the engagement is used to move and/or stop contiguous portions through the use of outwardly extending tabs at the rear and front ends of the telescopic portions. The guiding assemblies include channels through which wheels that are rotatably mounted to the lowermost ends of the portions. The stationary portion can be mounted to a cover member that is hingedly mounted to the area adjacent to a cooperative hole for selectively housing the retractable cover.
