Gravity will return the hook-like member 36 to the latched position when the first actuator subassembly 72 is rotated or returned from the second position to the first position.
As best shown in FIG. 4, the first actuator subassembly 72 comprises a cylinder lock 76 mounted to or on the upper portion of the latch housing 20 having an arm or cam member generally indicated as 78 operatively coupled thereto. The arm or cam member 78 comprises a first arm or cam element 80 coupled to the cylinder element 82 and a second arm or cam element 81 coupled to the upper portion of the second actuator subassembly 74. Of course, a simple first rotatable actuator lever may be substituted for the cylinder lock 76.
The second actuator subassembly 74 comprises a substantially vertical block 84 including a substantially vertical centrally disposed slot 86 formed in the upper portion thereof and a recess or shoulder 88 formed to one side of the
8491199_1 (GHMatters) P104795.AU
2016269463 07 Dec 2016 substantially vertical centrally disposed slot 86 to receive the second arm or cam member 81.
As best shown in FIGS. 5 through 8, the second actuator assembly 18 comprises a first actuator subassembly generally indicated as 88 movable horizontally between a first position and a second position disposed in behind the latch housing 20 and a second actuator subassembly generally indicated as 90 movable between a first or rearward position (FIG. 5) and a second or forward position (FIG. 7) disposed between the first actuator subassembly 88 and the second or lower latch extension or element 42 such that the second actuator subassembly 90 engages the second or lower latch extension or element 42 when the first actuator subassembly 88 is moved from the first position to the second position to rotate the hook-like member 36 upwardly clearing or unlatching the substantially horizontal striker pin 60 from the striker pin recess 38 allowing the gate (not shown) to be opened. Gravity will return the hook-like member 36 to the latched position when the first actuator subassembly 88 is released and the bias 102 returns the first position actuator subassembly 88 and the second actuator assembly housing 94 from the second position to the first position.
As best shown in FIGS. 5 through 8, the first actuator subassembly 88 comprises a plunger 92 partially retained within a second actuator assembly housing 94 by an outer retainer flange 96 disposed around the periphery of an outer plunger opening 98 and an inner retainer plate 100 and a bias or spring 102 disposed within the second actuator assembly housing 94 to normally maintain the first actuator subassembly 88 in the first position.
