Sicherheitstür

摘要

The securing bolts (15) can be pushed into guides by a lock so that in a bolt position they project over the corresp. peripheral edge of the door panel and in an unbolted position are accommodated in the door panel. The lock comprises a thrust bar (16) running crossways to the guides and displaceable in its longitudinal direction. The securing bolts are mechanically coupled to the thrust bar. In each guide a securing bolt is positioned and the bolts fitted to the one peripheral edge and to the opposing edge are displaced in relation to one another. Six laterally effective securing bolts are provided, of which the two lower and the two upper are effective on the lock side, and the two middle on the door-hinge side.
