Abstract
A protective bumper attaches to a caster wheel assembly and substantially surrounds the assembly to act as a point of contact with other objects or articles, in order to limit or prevent damage to struck objects, and/or to the caster wheel assembly, and/or to a movable object or article supported on the caster wheel assembly. The protective bumper includes an outer bumper portion and an inner frame portion that attaches to a frame of the caster wheel assembly. The bumper may be attached to the caster wheel assembly via an axle that rotatably couples a wheel to the frame of the wheel assembly. Optionally, the outer bumper portion may be fitted with a relatively soft annular outer member or surface.
