Abstract
A double self-latching double-locking gate latch mechanism includes a first latch bracket for attachment to one gate member and supporting a rotatable latch element for movement between latched and unlatched positions and having a locking plate member at one end for registry with a locking element of the bracket each forming a lock opening to receive a padlock at the latched position of the rotatable latch element. At its opposite end the rotatable latch element defines a transversely oriented elongate head. A second latch bracket is provided for attachment to a second gate member and forms a latch chamber that receives an elongate latch slide having a bifurcated extremity forming an elongate slot of sufficient width for passage of the T-head therethrough when the rotatable latch element is at its unlatched position with the elongate head of the rotatable latch element oriented transversely of the elongate slot. At the latched position of the rotatable latch element the latch slide is linearly movable to a retracted position for unlocking. The latch slide is capable of being restrained at its retracted position until it is released by closing force for movement to its latched posit…
