Abstract

A tool cabinet has rollers depending from a bottom wall for rolling engagement with an underlying floor. A retractable step is carried by a support arm which extends laterally from the step and has an upstanding shaft portion which extends through an axial bore in a spiral cam which is fixed to the bottom wall of the cabinet. The shaft has a cam follower pin which extends therefrom and is slidably engageable with a spiral cam surface on the cam for accommodating simultaneous pivotal swinging movement and vertical movement of the step between a stowed position disposed beneath the cabinet and above the floor and a use position extending from beneath the cabinet in engagement with the floor.
