Abstract
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.
