Abstract:
1. A rolling support assembly for an article comprising: a longitudinal load bearing member defining a load bearing member upper extent, a load bearing member lower extent, and a load bearing axis centered between the load bearing member upper and lower extents, wherein the load bearing member is oriented substantially parallel to a support surface, wherein the load bearing member upper extent defines a load bearing member height, and wherein the load bearing member is configured to support an article above the support surface, and; a caster assembly supporting the load bearing member and defining a height, wherein the caster assembly has a frame, a hub pivotally mounted to the frame and rotatable around a vertical axis, a wheel pivotally mounted to the hub configured to support the caster assembly above the support surface, and a cover mounted above the wheel, the cover defining an opening; wherein the wheel defines a wheel upper extent and the load bearing axis is below the wheel upper extent; wherein the wheel extends into the opening in the cover; wherein the load bearing member height as it laterally approaches the caster assembly is less than the height of the wheel; and wherein the load bearing member extends laterally from the caster assembly.
