Abstract

A modular positive mechanical door latch mechanism for a copier or the like is disclosed in Figure 1 that is adapted to be easily attached to a copier door by the use of screws 10 - 14. In operation, with a small amount of pressure of approximately 4 pounds handle 20 of Figure 2 is lifted upward and through linkage 21 lifts pawl 25 through pin 26 from pawl anchor 28 in order to open the copier door. When the handle is released it returns to its original position due to the action of tension spring 30 against linkage 21. When the copier door is closed, handle 20 for safety purposes remains stationary since as pawl 25 rides over pawl anchor 28 link 22 is allowed to slide upward by way of recess 21 in linkage 21 without moving handle 20.

The door springs open when unlatched due to the force of spring 32 as seen in...
