Abstract
Abstract A cabinet having an access opening and sliding panels each occupying more than slightly one half of said opening with notches aligned with each other at the base of each opening, a base for said cabinet comprising upper and lower base plates with a space therebetween, a relatively elongate rod having a finger section at its front end and secured near its rear end to the underside of the said upper base plate, the finger section extending into an aperture in the central front portion of said base plate disposed below the aligned notches in the panel, said finger section of the rod being accommodated in the notches when the panels are in closed position, a cross member secured at right angles to the rod intermediate the rod rearwardly of the finger section, a trim piece covering the space between the upper and lower base plates having a slot therethrough and a channel member forming a guideway with the slot extending toward the rear of the cabinet and secured to the front upper portion of the lower base plate, plus a shaped tool of predetermined dimension for extending into the slot in the trim piece and the guideway to the rear thereof for engaging the cross member to move it downwardly whereby the finger section on the rod is also moved downwardly out of contact with the blocking relation to the panels which are then free to move to open the cabinet, said finger section returning into blocking position automatically when the panels are closed and the notches realign above the aperture accommodating the finger section of the rod.
