ABSTRACT:
A gate latch for use with a gate mounted for pivotal movement relative to a stationary fence includes a transversely extending latch bar secured to the gate and a latch member pivotally mounted on a mounting plate secured to the fence. In a first embodiment, a safety latch attachment includes an adapter plate configured for partial overlying attachment adjacent the latch mounting plate and having a reciprocal spring biased plunger in alignment with a transverse aperture formed through a latch frame on the mounting plate. When in a latched position, the plunger prevents the pivotal latch member from being unlatched. A pulley guided cable is connected to retract the plunger to allow the gate to be unlatched. In a second embodiment, the safety latch attachment mechanism is provided as an integral unit on a common mounting plate with the pivotal latch member.
