Abstract
A door latch assembly operable from at least two remote positions including a pair of opposed latch arms pivotally supported by a latch bracket for engaging a latch bar, a movable link connected to the latch arms for pivoting the latch arms alternately toward a latched and unlatched position, a release lever for actuating the link to pivot the latch arms toward the unlatched position, and means for supporting the release lever, preferably a ball and socket connection, for movably supporting the release lever in engaging proximity to the link such that the release lever in engaging proximity to the link such that the release lever is movable about at least two angularly related axes.
Claims29
A door latch assembly comprising:
- support means;
- latch means for engaging a latch bar, said latch means being pivotally supported by said support means;
- movable link means connected to said latch means for pivoting said latch means alternately toward a latched position and an unlatched position;
- a release lever for actuating said link means to pivot said latch means toward the unlatched position;
- and release lever support means for movably supporting said release lever about at least two angularly related axes in engaging proximity to said link means such that said release lever is movable about each said axis to effect pivoting of said latch means.
A door latch assembly comprising:
- latch support means including at least one wall;
- means for attaching said latch support means to a door;
- a pair of opposed latch arms pivotally supported on a first side of said wall, one above the other and relatively laterally spaced apart;
- a movable link extending through an opening in said wall and connected to said latch arms for alternately pivoting said latch arms toward and away from one another;
- a release lever for actuating said link to pivot said latch arms away from one another;
- and release lever support means for movably supporting said release lever on the second side of said wall in engaging proximity to said link such that said release lever is movable about at least two angularly related axes whereby movement of said release lever about each said axis against said link moves said link through said wall causing said latch arms to pivot away from one another.
