ABSTRACT:
A linearly reversible caster assembly (30) capable of carrying a load (L) on a surface (S) comprising a pivotable U-shaped frame (34) coaxially mounted with a caster wheel (32) on an axle (48). A translatable U-shaped frame (36), suitably attached to the load (L), has a planar surface (56) that coacts with a rollable surface (42) carried by the pivotable frame (34). The rollable surface (42) has a radius greater than the wheel (32) whereby when it is desired to reverse the direction of travel of the load (L), and thus the assembly (30), the frame (34) will pivot about the axle (48) and the wheel (32) will remain substantially motionless. As a result, the eccentricity of the caster assembly (30) is changed and the wheel (32) is linearly reversed.
