Abstract

A caster pad permanently attachable to the underside of a receptacle to permit a caster to be quickly mounted to the receptacle by insertion into the caster pad and to be quickly removed from the receptacle by releasing it from the caster pad. In one embodiment, the caster pad employs no specialized parts but instead is formed from a single piece of sheet metal to which standard bolts are affixed for locking the caster into the caster pad. In addition to the bolts, the caster pad consists of a unitary piece of metal whose edges are bent out of the plane of its flat central portion to form flanges which help to retain the caster and which include threaded holes for attaching the bolts. In another embodiment, the plate of the caster is inserted laterally into the caster pad and is retained in position by a spring which, after being compressed for installation, expands to an installed position under the caster pad's retaining lips which previously loosely embraced the edges of the inserted caster plate, to jam the caster plate flush against the caster pad and to retain it in that position.
