Abstract

Disclosed is a double opening lift-off door which solves problems inherent in accessing covered enclosures. The usual approach to opening covers is to hinge them (left or right side) or remove them. Each approach requires multiple pieces of hardware, separate part numbers, and the decision as to which one will be designed into the main frame. This disclosure identifies one door which performs all functions simultaneously.

Double Opening Lift-Off Door

      Disclosed is a double opening lift-off door which solves
problems inherent in accessing covered enclosures.  The usual
approach to opening covers is to hinge them (left or right side) or
remove them.  Each approach requires multiple pieces of hardware,
separate part numbers, and the decision as to which one will be
designed into the main frame.  This disclosure identifies one door
which performs all functions simultaneously.

      To achieve the double opening door spring-loaded, retractable
pins are located top and bottom of each vertical edge.  The pins
serve either as latch or hinge, allowing the door to be opened from
either side.  If both sets of pins are retracted simultaneously, the
door can be lifted off.

      The figure shows a typical arrangement of components: (A) latch
block, (B) compression spring, (C) lift latch, (D) pin, and (E)
end/corner block.  Each fully functional door would have two latch
blocks, four pins, and two (if full top and bottom molding) or four
(if each corner a separate molding) end/corner blocks.  All parts are
simple to make and low in cost.  Options include locking both latch
blocks to prevent any access or one latch block could be locked to
insure one side only hinging (with no lift off).
