A biasing arrangement for a door 54 for closing an opening in a frame 50 comprising a pivotal door 54 mounted to a frame 50, and a stop member 72 provided on the frame 50 with a lever member 74 provided on the door 54 such that when the door 54 is moved relative to the frame 50, the stop member 72 and the lever member 74 interengage causing the door 54 to pivot around its pivot axis to draw the door 54 and frame 50 closer together. Adjustment in the position of the stop member 72 and the use of an hydraulic ram (fig 5a, 88) and solenoid may be used for closing and locking the door 54 in place against the frame 50. |
