Abstract: A collapsible shelter mounted on the roof of an automobile has a pair of pivotally connected platforms. A first platform is secured to a frame structure mounted on the roof of the automobile. A second platform is pivotally connected to the first platform and movable from a folded position over the top of the first platform to a second unfolded position adjacent the side of the first platform. A frame assembly cooperates with the platform to erect a tent cover during the pivot movement of the second platform to the open position. The frame assembly is associated with lifting and holding cords that move parts of the frame assembly to unfolded positions during the movement of the second platform to the open position. A ladder support attached to the outer side of the second platform supports the second platform on the ground in its open position.
