Gate latch assembly
First Claim
1. A gate unit comprisinga gate mount,a gate mounted on a portion of the gate mount for movement between an opened position and a closed position,a latch mounted on the gate, the latch including a latch retraction pin and a spring-biased post carrier having a plunger post connected thereto, the plunger post being biased to an extended position via a spring coupled to the post carrier and to the gate, and the post carrier further including a peripherally enclosed opening having a plurality of walls, one of the walls forming a substantially linear latch retraction ramp and wall sections of two of the remaining plurality of walls each forming a stop at a respective end of the latch retraction ramp, the stops preventing the latch retraction pin from moving beyond the ends of the latch retraction ramp, andlatch drive means mounted on the gate for interacting with the latch retraction ramp via the latch retraction pin to urge the spring-biased post carrier and plunger post to a retracted position.

8. A gate unit comprising
a gate mount including a latch receiver frame having a post receiver, a gate mounted on a portion of the gate mount for movement on the gate mount between an opened position and a closed position, and a latch assembly including a latch having a peripherally enclosed opening having a plurality of walls, one of the walls forming a substantially linear latch retraction ramp and two of the remaining wall sections of plurality of walls each forming a stop at a respective end of the latch retraction ramp, the latch assembly further including a plunger post configured to mate with the post receiver, a latch base, and a latch mover mounted for movement on the latch base to move the latch, the plunger post being carried on a post carrier of the latch and the latch having a guide slot configured to receive a guide pin coupled to the latch base, and the latch mover including a latch retractor pin which rides on the latch retraction ramp between the stops, the stops preventing the latch retractor pin from moving beyond both ends of the latch retraction ramp, movement of the latch mover in a first direction permits the plunger post to be urged into an extended position and into the post receiver when the gate is in the closed position.
