Abstract: An automatically or manually operable closure system for a closing flap on a transport container is situated on the container frame and a docking stand at an unloading station. A rotating device for moving the closing flap is provided on the docking stand and a locking device for locking the closing flap in the closed position is provided on the container frame. A flap shaft, whose other end is mounted rotatably in the container frame and is implemented as a first connection element, engages axially to the rotational axis of the closing flap. The first connection element is axially coupled using a torsion-fixed tongue-groove pair to an axially displaceable second connection element. Formfitting coupling elements are provided on the second connection element and on the driveshaft for moving the closing flap.

Abstract: An automatically or manually operable closure system for a closing flap (4) on a transport container (1) is situated distributed on the container frame (2) and a docking stand (3) at an unloading station. A rotating device for moving the closing flap (4) is provided on the docking stand (3) and a locking device for locking the closing flap (4) in the closed position is provided on the container frame (2). A flap shaft (5), whose other end is mounted rotatably in the container frame (2) and is implemented as a first connection element (7), engages axially to the rotational axis (24) of the closing flap (4). The first connection element (7) is axially coupled using a torsion-fixed tongue-groove pair to an axially displaceable second connection element (10). An axially acting compression spring (11) is situated between the two connection elements (7, 10). The second connection element (10) engages in a rotationally-fixed locking element in the closed position of the closing flap (4).
