Title: Electromechanical devices with emergency manual control for opening the doors of safety outfit boxes on aircraft
IPC: E05B17/20
Filed: 1975-04-10
Abstract: 1497617 Electromagnetically releasable fastenings R ALKAN & CIE 10 April 1975 [18 April 1974] 14811/75 Heading E2A  Door 2 may be opened by actuating an electromagnet. This pulls piston 6, against the bias of spring 21, so that ball-bearings 15, 16 are no longer in contact with portion 22 of the piston 6 but in register with a portion 24 of smaller diameter. Consequently, they may move towards each other leaving the holes 14 in wings 10; 11 of hook 7 and so allowing this hook to pivot, in response to the urging of spring 9, about axis 8. This tilting of the hook permits the bar 18, attached through strap 17 to door 2, to escape from the hook and the door 2 will then be opened by spring 4. The mechanism also provides means for keeping the door open. Hook 7 is prevented from pivoting beyond a certain point by means of lug 26 impinging on stop 27. At this point holes 23 in wings 10, 11 of the hook 7 are in register with the holes 14 and the ball bearings in them and so, removal of the electromagnetic stimulus permitting the piston 6 to return to its original position will mean that the wide portion 22 on the piston contacts the bearings, forcing them outwards and into holes 23. The door 2 is then held open and cannot be shut without a deliberate action.  Means for shutting the door, and also for opening it manually in an emergency, are provided by control device 31. To close the door a rod 28 may be inserted through hole 29 in the body of the container to push the head 35 of the device. This tilts lever 36 and so pushes against the end 30 of the piston 6. The piston then moves in the same manner as under the influence of the electromagnet, permitting the balls 15, 16 to fall out of the holes 23 and allowing the door to be closed.  A hole 29 is also provided in the door 2 and by inserting a push-rod 28 through either this hole 29 or the other the piston 6 may be actuated and the door 2 opened in an emergency.
