Abstract

Abstract A leveling and stabilizing device for trailers, campers and related vehicles. One or more skid members are pivotally mounted from supporting frame members on the underside of the vehicle for swinging rearwardly in vertical, longitudinally oriented planes. Corresponding pressure members are operatively connected between each skid member and the corresponding frame member from which it is mounted to depress the skid member in order to elevate one or both sides of the vehicle. An elastic member is also operatively connected between each skid member and the frame members to elevate the skid member. Stops are provided to maintain the dimension between each skid and the roadway over which the vehicle is traveling at a lesser dimension than that between wheel rims on the vehicle and the roadway.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 121 words
A vehicle comprising; a frame having side members, at least one wheel means on each side of the vehicle and supporting said frame, a tongue for drawing the vehicle, jack means mounted on said tongue to effect pitch-type leveling, means pivotally mounting a skid on each said side member adjacent each side wheel means, each said skid being directed downwardly and rearwardly with respect to the vehicle and movable in a vertical plane parallel to said wheel means, a pair of cylinders each operative selectively to extend an individual piston rod, one said cylinder and its associated, individual piston rod being connected between each side member and the skid member pivotally mounted therefrom for moving selective skids to effect roll-type leveling.
Claim 2
Dependent Claim 121 words
A vehicle comprising; a frame having side members, at least one wheel means on each side of the vehicle and supporting said frame, a tongue for drawing the vehicle, jack means mounted on said tongue to effect pitch-type leveling, means pivotally mounting a skid on each said side member adjacent each side wheel means, each said skid being directed downwardly and rearwardly with respect to the vehicle and movable in a vertical plane parallel to said wheel means, a pair of cylinders each operative selectively to extend an individual piston rod, one said cylinder and its associated, individual piston rod being connected between each side member and the skid member pivotally mounted therefrom for moving selective skids to effect roll-type leveling.
Claim 3
Dependent Claim 59 words
A vehicle, as set forth in claim 1, in which said wheel means have tires mounted on rims and a head is secured to said piston rod, said head engaging said cylinder to maintain the dimension between said rims and the roadway over which the vehicle is traveling greater than the distance between each said skid and the roadway.
Claim 4
Dependent Claim 19 words
A vehicle, as set forth in claim 2, in which further means are provided individually to elevate said skids.
