Abstract (en)
[origin: EP0255991A2] This safety device is effective to inhibit opening of a door in case of failure of the pneumatic system; it is primarily useful with so-called inward rototranslation doors wherein each door wing has a top-mounted peg (4,5,103,202,302) guided slindingly in a track (6,104,203,303) overlying the door. The device comprises a checking member (7,8,105,209-210,315) in said track which is movable between a home position whereat it does not interfere with the peg (4,5,103,202,302) and an operative position whereat it holds the peg back; this member (7,8,105,209-210,315) is held at its home position by the pneumatic system against the bias of springs (16,23,120,215,320) in such a manner as to be automatically brought to its operative position on the occurrence of a failure.
