A door mounted to slide across an opening in a structure (for example, a vehicle body) has a handle(11) pivotally, or slidably, mounted on the door and biassed to a central position by springs (18, 19) acting on an arm (14). Movement of the handle in one direction (to open the door) causes release of the door latch by the arm (14) pulling a rod(20) and operating a pivoted lever (24) and an operating rod (25). Simultaneously, a connecting rod (29) is pushed, rotating a lever (28) to open a second latch (27) for securing the door in an open position. Continued applioation of force to the handle (11 ) in the same sense draws the door across the opening to latch it in an open position. Pivoting of the handle (11) in the opposite direction causes the arm (14) to push the rod (20) and lever (24) pulling the connecting rod (29) and rotating the lever (28) to release the second latch (27). The operating rod (25) does not move because of a lost motion connection (26) with the lever(24). Continued application of force to the handle 11 draws the door back across the opening to latch it in the closed position. The latches may also be operated by a handle (31) of the second latch (27) inside the vehicle. |
