Abstract: A wheel suspension system for a vehicle such as a truck trailer. Wheels of the suspension system are attached to stub axles supported by pivoting trailing arm wheel supports. The wheel supports are arranged on a sub-frame which can be slidingly coupled to the underneath of the trailer. Each wheel support is urged apart from the sub-frame by a spring such as an air spring. In one embodiment the air springs are pressurized under the control of an electronic controller. The rotational axes of the wheels are staggered or spaced apart, such that the rotational axes of the wheels on one side of the sub-frame are not coincident with the rotational axes of the wheels on the other side of the sub-frame.

Abstract: Chairs constructed of fiberboard with an easily assembled core structure, reinforced arms, and an outer casing that economically consumes raw sheeting material by minimizing stamping waste. The chairs include a casing, a core structure, and a body panel. The core is built from aligned L-shaped members and transverse struts that mutually connect by interfitting slots. The casing is built from a rectangular tube. The tube has side sections, a front section and a rear section. For the versions with arms, the side sections carry flaps that reinforce the arm areas. For the versions without arms, the side sections carry flaps that fold over the L-shaped members. The body panel resides over the back support area and the seat support area of the L-shaped members and provides a uniformly smooth surface. The chairs may be combined or aligned in series to form a sectional couch.

Abstract: A wheel suspension including a wheel support pivotally attached to a vehicle frame at two, laterally-spaced locations, the wheel support being pivotable between uppermost and lowermost positions, a wheel rotatably mounted to the wheel support, a leaf spring mounted between the vehicle frame and the wheel support to bias the wheel support to a position intermediate the uppermost, and lowermost positions, and a second biasing device, such as an air bag or coil spring, mounted outside of the vehicle frame and biasing the wheel support to an intermediate position.

Abstract: Trailer suspension apparatus for increasing the cargo capacity of the trailer. The apparatus includes a U-shaped frame having a transverse structure and upright structures at the ends of the transverse structure. The trailer wheels are disposed in the upright structures with the upright structures being at least in part over the tracks of the wheels. The wheels are resiliently suspended from the upright structures. The transverse structure is positioned beneath the rolling axes of the wheels to permit the trailer body to provide cargo space between the wheels and over the transverse structure.
