摘要： The locking device is capable selectively of taking up a first operating e for use in the presence of the public in which it provides positive safety unlocking under remote control by interrupting the current feeding an electromagnet, and a second operating mode for use when the public is absent, and which is more secure. The device includes a bolt pivotally mounted about a bolt axis. The pivoting bolt co-operates with a retraction spring which has energy stored therein when the bolt is in its door-closing position, and also with a locking piston which is guided by a guide part to move perpendicularly to the axis. The bolt-locking means includes a toggle mechanism comprising a first link that pivots about a fixed first axis, and a second link hinged about a moving second axis to the first link and about a moving third axis to the piston. The moving second and third axes are parallel to the fixed first axis. In the locked position, the axes are substantially in alignment along the displacement direction of the piston and a toggle-collapsing spring has energy stored therein.
