ABSTRACT:
A door panel latching apparatus including first and second elongated rods telescoped together for relative sliding movement. The first rod is mounted to the door with a free end for latching near an upper door edge and free to rotate about its longitudinal axis but is prevented from moving longitudinally. The second rod is mounted to the door with a free end for latching near a lower door edge and free to rotate about its longitudinal axis and to move along its longitudinal axis. A handle is connected to the rods by a linkage for longitudinally moving the second rod when the handle is rotated about an axis perpendicular to the longitudinal axis of the rods and for rotating both rods when the handle is rotated about an axis which is coincident with the longitudinal axes of the rods.
