Abstract
Abstract A latch assembly for a hinged double gate structure which permits opening of one gate while the other gate remains latched in closed position or opening of both gates simultaneously. The latch assembly has a latch rod slidably supported by brackets to be attached to the outer vertical edge of one gate for vertical endwise movement of the lower rod end into and from latching engagement in a latch socket or the like embedded in the ground to releasably latch the gate in closed position. Pivoted on the upper end of the rod is a latch yoke which is swingable to and from a latching position wherein the yoke is disposed to straddle the outer edge of the other gate when in closed position to latch the latter gate closed. This latch yoke may be retracted from latching position to release the latter gate for opening while the remaining gate remains latched in closed position by the latch rod. The latch yoke and rod may be retracted from latching position simultaneously to release both gates for opening. The latch rod and yoke may be locked in latching position to lock both gates in closed position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A latch assembly for a hinged double gate structure including a pair of hinged gates swingable to and from closed positions wherein the gates are located substantially in a common plane with vertical edges of the gates adjacent one another comprising: a normally generally vertical latch rod having a normally upper end, mounting bracket means slidably receiving said rod including means for attaching said bracket means to said edge of one gate with said rod extending along the edge, anti-rotation means for restraining said rod against rotation on its longitudinal axes relative to said bracket means, a latch yoke including a pair of spaced yoke arms, a connecting portion joining said arms at one end, and a tongue extending from said connecting portion, and means pivotally connecting said yoke tongue to the upper end of said rod on a pivot axis transverse to the rod for swinging of the yoke between a gate latching position wherein said yoke arms extend transversely of the rod for straddling said edge of the other gate and gate releasing position wherein said yoke arms extend generally longitudinally of said rod.
Claim 2
Dependent Claim
