An angular lever for guiding and moving a door leaf is rotatably mounted in a horizontal plane in the direct vicinity of the door frame. One limb of the angular lever is permanently connected to a guide rail of the door leaf, and the other limb temporarily engages with a control element on a guide unit to swing the door leaf. In order to open completely and subsequently close the door leaf, a guide arm of the door leaf is operatively connected to the control element. During the closing movement of the door leaf, an operative connection of the guide arm to the control element is released and the other limb of the angular lever engages again with the control element. When the angular lever assumes its home position, it presses the door leaf firmly against a door seal and locks the door leaf.

Swinging and sliding door for rail vehicles

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.

An engagement element is provided on the inside of the door leaf or of the door at a defined distance from the inside of the door. A spring-loaded locking hasp lies horizontally opposite the engagement element on the inside of the door frame. The locking hasp has a semicircular or claw-shaped recess and a laterally projecting locking section. A locking element is movably guided inside the door frame and connected to a vertically movable rod. During the closing movement of the door, the engagement element engages with the recess of the locking hasp, which swings with its locking section in the direction of the center of the door opening and assumes a position parallel to the door and is locked in this position by a movement of the locking element which is triggered in the vertical direction.
