Abstract
A camper unit, adapted to be mounted on a vehicle, has a boxlike structure whose front, top and rear walls are formed in one piece of said foam plate sandwiched between aluminum layers with the angular junctions between these walls formed by mitering the hard foam and bending the outer aluminum layer so that edges of the hard foam plate are adhesively bonded together. The lateral walls are connected to the front, top and rear walls by connecting strips which are mitered at their ends to join one another all around the lateral walls and are welded to mitered junctions. A T-section member is affixed to the walls of the boxlike structure in a horizontal plane and circumferentially thereof to support the floor which is likewise formed as a hard foam plate sandwiched between layers.
Claims10
A camper structure adapted to be mounted on a vehicle chassis and comprising:
- a one-piece element defining a front wall, a top wall angularly adjoining the front wall and a rear wall angularly adjoining said top wall at respective angular junctions, said one-piece element being composed of a hard-foam plate sandwiched between aluminum layers, an outer one of said aluminum layers being bent at each of said junctions, said plate being mitered at each of said junctions to form adjoining edges adhesively bonded together;
- a pair of side walls extending perpendicularly to the front, top and rear walls, said front, top and rear walls being connected to said side walls by connector strips each receiving an edge of said side wall and an edge of a respective one of said front, top and rear walls, said connector strips extending peripherally all around said side walls and adjoining one another at abutting mitered edges at which said connector strips are welded together so that the connector strips around the periphery of each side wall form a closed stabilizing ring, each of said side walls being composed of a hard-foam plate sandwiched between aluminum layers;
- a T-section member lying substantially in a plane perpendicular to said front, rear and side walls and adhesively bonded to inner ones of said aluminum layers of said front, rear and side walls in a circumferentially closed configuration whereby a flange of said member projects inwardly all along said circumferentially closed configuration;
- a floor composed of an insulating foam plate sandwiched between upper and lower layers secured from below to said flange all around said circumferentially closed configuration;
- and
- reinforcing connecting strips extending along the bottom of said rear wall and across said front wall and welded to said rings whereby said strips, said walls and said floor form a self-supporting box.
