(57) This safety device is intended to inhibit a door of a means of public transport from
being opened while it is subjected to a thrust force directed from the inside out.
The device is particularly useful with so-called inward rototransia- tion doors wherein
each door wing (2) has a top-mounted peg (9) guided slidingly in a track (11) overlying
the door, and comprises a section (16) of said track adapted to yield in an outward
direction, located at the peg (9) with the door wing (2) in the closed condition.
Thus, if the door wing (2) is thrusted upon, the peg (9) can be taken out of its track
(11) and prevented from sliding, thereby the door cannot be opened.
