ABSTRACT:
A portable shelter assembly adapted to be mounted in a folded condition for transportation purposes preferably on the top of a motor vehicle, and to be unfolded and distended while supported either on the vehicle or on the ground to provide a tent for shelter purposes. The assembly includes a pair of rigid base sections hingedly secured together at inner edges and foldable to define a container in which the remainder of the tent can be stored, and unfoldable to define a planar platform with upturned forward and after edges on which a flexible cover and frame members can be supported to provide accommodations. A simplified hinge arrangement for the base sections and the associated pivotally supported frame members is provided, and the flexible cover, when distended, provides for interior ventilation and improved exterior drainage.
