ABSTRACT:
A gate latch device shown for swinging and sliding gates. In the swinging gate embodiment, a latch bar rides over a strike plate until a notch in the latch bar is engaged. A pin is simultaneously depressed by contact with the strike plate which releases a latching pin or bolt to immobilize the latch bar until a manual release is effected from a visually non-obvious location. For a sliding gate, concentric mutually slideable tubular members are provided, one mounted to the sliding gate and the other carrying an articulated jaw which engages a pin or bolt on a fixed structure on a fixed structure to which the gate is closed. A combination lock is adapted to lock the tubular members together.
