Abstract
Casters are detachably mounted upon the underside of the molded plastic frame of a dolly by the use of a single bolt. The caster is provided with a flat, horizontally disposed mounting plate which underlies and bears against a horizontal surface on the bottom of the frame enclosed within a peripheral sidewall integral with and projecting downwardly from the frame. The mounting plate can be vertically moved into face-to-face engagement with the horizontal surface on the frame when in a first angular orientation and then rotated about a vertical axis to a second angular orientation in which webs on the sidewall spaced below the horizontal surface underlie portions of the plate to retain it against vertical separation from the frame. A single bolt detachably retains the plate against rotation from this last position.
