Abstract: A shock resistant caster includes two structures one of which is connectable to a unit to be supported, and the second of which carries a wheel and is connected to the first structure for pivotal movement relative thereto. A cushion formed of elastomeric material is positioned to be compressed upon imposition of a load on the caster, to attain a cushioned support of the load, and may be held in position by a locating pin connected to one of the two relatively movable structures and extending through a passage in the cushion. The wheel preferably has an elastomeric portion formed of a material which is softer than the elastomeric material of the cushion, with the overall effect of the entire assembly being to produce a ride which is soft under low load conditions and becomes progressively stiffer in non-linear fashion as the load increases to optimize the support of the carried unit under all conditions.

Abstract: A shock resistant caster assembly having a wheel positioned in a housing formed of at least two sections vertically displaceable with respect to each other, one of the housing sections being coupled to the wheel at its rotational axis. A shock pad of elastomeric material is positioned between the housing sections for resiliently cushioning the vertical displacement between the housing sections.
