Abstract
Abstract A camper trailer which is collapsible and entirely made of rigid panels. The camper trailer comprises an open top box-like body, a main roof, means to raise the main roof, longitudinal wall panels hinged to the longitudinal sides of said body and, when erected, closing the space between the main roof and the said longitudinal body sides. Extensible parts, entirely made of rigid panels hinged one to the other, can be moved out to protrude from the body and main roof. Each extensible part comprises a horizontal platform mounted on slides, a roof made of panels hinged to the outer end of the platform and to the underside of the main roof and movable in slides under said main roof and of longitudinal panels hinged to the sides of the platform and capable of taking an upright position engaging the roof of the extensible part. The main roof is raised by a system of bars actuated by a winch and cable arrangement.
