ABSTRACT:
An emergency unlocking device for locking and unlocking systems for swinging sliding doors, in particular of rail vehicles. The emergency unlocking device has a traction device that engages on a first spring-loaded pivoted lever that is connected via a second lever to a third lever. The third lever is attached to the axial shaft of a spring-loaded rotary magnet and has elongate holes in which a bolt is displaceably mounted. When the traction device is subjected to tensile stress, the bolt engages with a fourth lever that is pivotably mounted on a shaft, and moves the fourth lever. The fourth lever is operatively connected via a coupling rod and deflection unit to a locking rod that moves the vertical direction. A rod, via which a force component that brings about the locking and unlocking of the door leaves can be applied, engages on the fourth lever.
