Abstract
Abstract A camper body of the type adapted to be carried in a ''''pickup'''' truck is provided with a pair of pivoted legs on each side. The lower ends of the legs on either side are pivoted to a longitudinal ground support member such as a channel member in the provision of a shoe. These ground support members or shoes provide a degree of stability which is not afforded by conventional jacks and make it possible to separate the camper body from the pick-up truck by simply moving the truck in reverse. A diagonal cable arrests the movements of the legs to positions of clearance between the camper body and the truck. To reload the camper body on the truck the truck is simply moved under the camper body and the two are coupled, such as by means of a cable, whereupon the truck is moved forwardly thereby reversing the process. When the camper body is resting on its ground support members removable lateral braces are also provided between the camper body of each ground support member to provide increased stability. Further increased stability is provided by a lateral cable which connecs the two ground support members or shoes and these ground support members are provided with tread means for anti-slip purposes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
263 words
The improvement in a camper body adapted to removably fit in a pick-up truck said improvement comprising parallelogram linkages connected to either side of the camper body and extending downwardly to ground level when the camper is on the pick-up truck, said linkages on either side of the camper body comprising a single elongated longitudinal ground engaging shoe member and front and rear legs pivotally connected at their lower ends to the ground shoe member and pivotally connected at their upper ends to the camper body to provide unitary structure, said legs of each unitary structure to each side of the camper body being longer than the vertical distance between their upper ends and ground level in the provision of a camper body lift with off center action of the said legs forwardly or rearwardly of the longitudinal axes of the truck and camper body, and a diagonal cable between the lower end of the front leg and the upper end of the rear leg to arrest the said off center action of the legs of the linkage in a given position of forward or rearward off center support for the camper body independently of the truck said improvement further including a lateral brace at each camper body corner, said brace comprising an elongated post, said post having an upper section mounted to each one of said camper body corners, and a lower section mounted to one of the corresponding ground engaging shoe members, said sections being formed to telescope together for manual adjustment, and means for locking said sections in adjusted positions.
