(57) Abstract :
A gate latch is adapted to be installed on a gate post and a complementary striker arm is secured typically to a gate so that, upon
closure of the gate, the striker arm engages a displacable latching element mounted in a housing of the latch to displace the latching
element. The latching element is biased towards its open position but when the striker arm engages with the latching element it is
displaced, thereby releasing an interference portion of a biased locking element, whereby the locking element is released to move
under its biasing into a locking position so that self-locking is provided for the latch. A rotary release mechanism may be actuated to
return the locking element so that they latching element can be released to release the striker bar and the gate may be opened.
