  • Patent number: 8087704
    Abstract: A latch for a pivotal door has a respective pair of bolts on each of two opposite edges of the doors. The bolts are independently movable between latching positions projecting from the respective door edge and freeing positions at least partially recessed in the respective door edge, respective rods having outer ends connected to the bolts and inner ends. Respective actuating elements each connected to two of the inner ends are independently operable to shift the respective bolts between the respective latching and freeing positions. Respective adjacent handles coupled to the actuating are both shiftable independently of each other in generally the same direction between an unactuated position with the respective element setting the respective bolts in the latching positions and an actuated position setting with the respective element setting the respective bolts in the freeing positions.
