Especially for use with a door panel 8 hinged on a frame 6 for relative swinging movement is a device 13-14 for so swinging the panel relative to the frame, the swinging device being responsive to a switch. An arm 26 journalled on an eccentric hub 24 rotatable with the door frame is movable in one direction against a stop 28 and in the other direction against a switch 31 that controls the operation of the panel swinging device, in this way affording an easy and proper control of power door operation. The door controlling mechanism 13 is actuated either by hydraulic means acting against a spring mechanism mounted in a housing 14 or by compressed air supplied through a line 22 and a switch operated power source 21. <IMAGE> |
