Gate latch assembly
First Claim
1. In a gate latch assembly for releasably holding a gate in a closed position relative to a gate post, said latch assembly, comprising a latch bar, connecting means adopted to connect the latch bar to said gate so that the latch bar extends beyond a free edge of said gate, a latch frame, including connecting means adapted to connect said latch frame to said gate post, said latch frame, including an outwardly opening slot into which said latch bar is received when said gate is closed, a pawl pivotally connected to said latch frame and including an outwardly facing cam surface to be engaged by said latch bar, causing said pawl to pivot upwardly when the gate is closed, said pawl, including a recess opening to receive the latch bar as the pawl is pivoted upwardly upon movement of the latch bar into the outwardly opening slot in the latch frame, the recess opening of the pawl being defined along one side by a wall surface thereof traversing the slot in the latch frame when the gate is closed to trap the latch bar in the slot, the improvement wherein spring means is provided in contact with said latch bar such that said latch bar, although being capable of deviating from a horizontal orientation, is biased to assume such an orientation.

Abstract
A gate latch assembly which includes a latch bar fixedly attached to a swingable gate is received into a slot in a latch frame. The latch frame is fixedly attached to a gate post enabling the gate to swing from the gate post upon the actuation of pawl releasing the latch bar. A number of modifications have been made to the standard gate latch assembly in order to improve its overall function and usability.

- 4. In a gate latch assembly for releasably holding a gate in a closed position relative to a gate post, said latch assembly, comprising a latch bar, connecting means adopted to connect the latch bar to said gate so that the latch bar extends beyond a free edge of said gate, a latch frame, including connecting means adapted to connect said latch frame to said gate post, said latch frame, including an outwardly opening slot into which said latch bar is received when said gate is closed, a pawl pivotally connected to said latch frame and including an outwardly facing cam surface to be engaged by said latch bar, causing said pawl to pivot upwardly when the gate is closed, said pawl, including a recess opening to receive the latch bar as the pawl is pivoted upwardly upon movement of the latch bar into the outwardly opening slot in the latch frame, the recess opening of the pawl being defined along one side by a wall surface thereof traversing the slot in the latch frame when the gate is closed to trap the latch bar in the slot, the improvement wherein said pawl is functionally attached to a cable at the proximate end thereof which passes through said gate post and is connected to a bell crank at a distal end thereof such that when pressure is applied to one end of the bell crank, the bell crank is caused to pivot about a fulcrum which, in turns, raises said pawl to release and eject said latch bar.
