Abstract:
A trailer having earth-traversing and stowing modes, comprising:a load-supporting frame having front and rear ends and opposite sides, said frame providing a trailer bed lying in a generally horizontal plane when in the earth-traversing mode;a pair of transversely spaced suspension arms having front ends individually pivotally mounted on the front end of the frame for independent elevational movement of the arms relative to the frame when the trailer is in its earth-traversing mode, said arms extending rearwardly and outwardly and having rear portions restively extending along opposite sides of the frame;a pair of transversely spaced ground-engaging wheels individually mounted on the rear portions of the arms adjacent to the opposite sides of the frame for elevational movement with the arms, the peripheries of the wheels extending upwardly in adjacent relation to the trailer bed in said earth-traversing mode and also extending rearwardly in adjacent relation to the rear end of the frame; anda pair of shock-absorbers connected to the frame and the respectively adjacent rear portions of the arms so that each shock-absorber, working through elevational movement of its associated arms can maintain the trailer bed in a generally horizontal attitude when stationary and during earth-traversing movement and can also maintain traction of the wheels with the ground.
