Mounting means for a door of sheet material

Abstract

This device includes: (a) an access opening, (b) support structure located adjacent an edge of the access opening and containing a plurality of slots, and (c) a sheet-metal door having one edge located adjacent the support structure, having a closed position covering the access opening, and having a fully-open position in which the door is perpendicular to its position when closed. The door is swingable between its closed and fully-open positions about a pivot axis located near said one door edge. The door includes a plurality of tabs projecting outwardly from said one edge, each tab being of a generally L-shaped cross-section when viewed from a reference plane perpendicular to the pivot axis. Each tab comprises a first arm located in the major plane of the door and a second arm extending transversely of the first arm. The second arm fits in an associated one of the slots and includes an extension extending laterally of the second arm beyond one end of the slot into a region behind the support structure when the door is in its closed position. When in its fully-open position, the door is laterally movable while the second arm is in its associated slot to a sufficient extent to shift the extension into a position of alignment with the slot, thereby allowing the door to be removed from the support structure.
