Abstract
Abstract The top of the van includes a perimetrical wall defining an opening with a hinged cover panel which opens to a horizontal position on one side of the van. A tent or enclosure is secured by the edges, around the perimetrical wall of the opening and around the free edges of the cover panel. A plurality of hoop braces are hinged to the wall and to the cover panel and the flexible enclosure is secured to these hoops so that the hoops are erected when the cover panel is opened. The cover panel is supported horizontally in the opened position by means of tension cables extending from the other edge of the opening, to the hoop braces to which it is secured, and is then secured to the distal edge of the cover panel by the other end thereof thus eliminating any need for vertical supports. If desired, a flexible porch can be detachably secured around the three edges of the cover panel when open, and can depend therefrom to the ground. Access to the upper tent portion is from the interior of the van through the opening in the roof thereof uncovered when the cover panel is open.
