Abstract:
A device for locking a container to a vehicle chassis, comprising a housing (1, 31) which on a housing side toward the container is provided with a protruding guide block (2, 32); having a rotary knob (3), which is supported in the housing (1, 31) and which has a shaft (4), guided in the guide block (2, 32), a hammerhead-shaped locking portion (5) protruding past the guide block (2, 32), and an actuation portion (6) disposed on an opposite housing side, the locking being effected by rotation of the rotary knob (3) about an actuation angle (15) of approximately 90.degree., in that the guide block (2, 32) having a rotation limiting portion (17) with at least two stops (18, 19) acting in the rotational direction; the rotary knob (3) having at least one radially protruding extension (22), which limits the rotation of the rotary knob (3) in both rotational directions, by contact with the respective stops (18, 19) of the rotational limiting portion (17), to the rotational range of the actuation angle (15) between a locking position (14) and a release position (13), the stops (18, 19) being formed by two opposed parallel walls (20, 21) of the rotational limiting portion (17); and the extension (22) of the rotary knob (3) having a cross section originating in a square basic shape with rounded corners, and two first rounded features (23) forming some of the rounded corners extending opposite one another, spaced apart essentially by the spacing (24) between the parallel walls (20, 21), over an angular range of approximately 90.degree., and second rounded features forming the remainder of the rounded corners and having a greater spacing from another than the first rounded features.
