ABSTRACT:
An expandable retractable portable structure having a movable portion hingedly connected to a stationary portion and wherein the movable portion pivotally encloses the stationary portion of the structure in its retracted position and wherein, in its expanded position, the structure provides maximum interior space for use. An actuating mechanism includes one or more hydraulic or pneumatic cylinders connected to a linkage system. The actuator is located inside the structure on the floor of the stationary portion and the linkage system driven by the actuator is connected to the floor of the movable portion so that the movable portion is rotated by the actuator and linkage system between its expanded and retracted positions. The actuator and linkage system are removably mounted inside the structure and may be readily removed from the structure and used to open or close other structures. Alternatively, the actuator may be left inside the structure.
