<p>A door and handle assembly (1) has a door (2) hinged about axis (3) on a door frame (4). A bar (8) is arranged across the door (2) and passes through a spring loaded latch member (5) retractable from recess (7) in the door frame (4) by cam means (8a, 8b, 8c) cooperating with detent means (5b). The bar (8) is moved longitudinally to retract the latch member (5) by actuation of either curved actuating plate (9b, 10b) in the direction of the arrows as shown in (Fig. 1). The plates (9b, 10b) are hinged to the bar (at 11 and 12) and hinged to flat plates (9a, 10a at 15, 16); the flat plates are screwed to the door. In one modification the plates (9a, 10a) are interconnected by a U-shaped bridge piece which extends around the edge of the door (2) and through which the latch member (5) passes. In a second modification the latch member (5) is hollow and the spring is located inside the latch member.</p> |
