ABSTRACT:
A child resistant latch having a latch operating assembly comprising a latch operating assembly and a striker bar or keeper plate assembly, one of which is supported on a gate and the other of which is to be supported on a gate post. The latch operating assembly comprises a closed box supported a predetermined distance above the striker bar or keeper plate assembly to permit operation only by an adult or tall child. A locking latch member is supported for vertical movement into and out of latching engagement with the striker bar or keeper plate. A guard box surrounds the striker bar or keeper plate when the latch member is in latching position to prevent opening other than by said operating means. A guide tube extends to a point just above the guard box and has a reciprocally movable rod guided for movement therein which interconnects a key-operated, latch operating lever and the latch member for movement in a vertical direction. A flange is provided on the latch control rod at a desired height for lifting the locking latch from its position atop the striker bar. The latch encasement, length of the control rod, and protective and concealing tubing, serve to prevent the opening of the gate by individuals who cannot reach the flange. An opening is the back wall of the guard box allows the latch control rod to move in and out of the box during opening and closing movement of the gate.
