Disclosed herein is a latch mechanism which can be easily opened by disabled individuals. On one side of a door or panel is a knob which can be pushed to unlatch the door by urging a plunger from an extended position to a retracted position. Further pushing on the knob moves the door to an open position. On the other side of the door is a knob which can be pulled to unlatch the door. Further pulling on this knob moves the door to an open position. Each knob is substantially flush with the door so that the latch is not opened by accidental bumping, and so that, prior to installation, the door can be stacked with other like doors or panels for storage or transportation.

A push-pull door latch mechanism for use with a door having first and second opposite side surfaces each having therein an aperture and having an edge surface between said first and second side surfaces, the end surface having therein an aperture, said mechanism comprising: a first escutcheon for being housed in the aperture of the first surface of the door, said first escutcheon having therethrough an aperture and defining a first recess; a second escutcheon for being housed in the aperture of the second surface of the door, said second escutcheon having therethrough an aperture that is aligned with said aperture of said first escutcheon along a push-pull axis, said second escutcheon defining a second recess; a push knob housed in said first recess and movable between a rest position and a pushed in position such that said push knob is substantially flush with said first escutcheon when said push knob is in said rest position; a pull knob housed in said second recess and movable between a rest position and a pulled out position such that said pull knob is substantially flush with said second escutcheon when said pull knob is in said rest position; a first shaft member movable along said push-pull axis between a rest position and a displaced position, said first shaft member including a first end connected to said pull knob and a second end having therein a socket; a plunger movable in the aperture in the edge surface of the door between an extended position and a retracted position; a lever mechanism between said first shaft member and said plunger, said lever mechanism moving said plunger from its extended position to its retracted position in response to said first shaft member moving from its rest position to its displaced position; and a second shaft member having a first end connected to said push knob, a second end movable in said socket of said first shaft member and a shoulder which engages said second end of said first shaft member to move said first shaft member from its rest position to its displaced position when said push knob is moved from its rest position to its pushed in position whereby movement of said pull knob from its rest position to its pulled out position does not cause movement of said push knob to its pushed in position.
