Abstract

A container locking device on a vehicle (F), for locking a container to be transported on a loading surface of the vehicle and having a corner fitting, comprising a lock housing (1), a locking bolt (2) and a drive (3), said locking bolt (2) having a shaft (20) and a locking head (21) which, in the unlocked state, can be introduced via an opening in the corner fitting of the container and, in the locked state, secures the container via projections engaging behind the opening in the corner fitting, the locking bolt (2) with its shaft (20) being mounted so as to be both axially movable in the lock housing (1) and also rotatable about its axis. A wedge slide (4) is mounted in the lock housing (1) so as to be movable to and fro laterally, that is to say perpendicularly to the axis of the locking bolt (2), and can be driven by the drive (3), and the wedge slide (4) has a lead-in slope which engages with the locking bolt (2) during the lateral movement of the wedge slide (4) and allows the locking bolt (2) an axial movement and a rotary movement about 90°, a horizontal lock bolt (7) being mounted in the lock housing (1) so as to be axially and horizontal movable. The invention also relates to a container locking method for said container locking device.

Dependent claims

A container locking device on a vehicle (F), adjustable between a locked state for locking a container with a corner fitting (9) to be transported on a loading surface (13) of the vehicle (F) and an unlocked state in which the container can be loaded and unloaded, comprising a locking housing (1), a locking bolt (2) and a drive (3), wherein

the locking bolt (2) has a shaft (20) and a locking head (21), which in the unlocked state the locking bolt (2) can be inserted via an opening in the corner fitting (9) of the container and in the locked state the locking bolt (2) secures the container via projections engaging behind the opening in the corner fitting (9),
the locking bolt (2) is mounted with the shaft (20) of the locking bolt (2) both axially displaceable and rotatable about an axis in the locking housing (1),
a wedge slide (4) is mounted in the locking housing (1) so that the wedge slide (4) can be moved back and forth laterally, i.e. perpendicular to the axis of the locking bolt (2), and can be driven by the drive (3),
the wedge slide (4) has a ramp which engages with the locking bolt (2) during the lateral movement of the wedge slide (4) and gives the locking bolt (2) an axial movement and a rotational movement through 90°,
a horizontal locking bolt (7) is mounted in the locking housing (1) so that the horizontal locking bolt (7) can move axially and horizontally, wherein a gooseneck container in a loaded state of the gooseneck container is arranged on the vehicle (F) with its corner fitting (9) horizontally adjacent and flush to the locking housing,
the horizontal locking bolt (7) has a free end (71) which, in an unlocked state of the horizontal locking bolt (7), does not protrude laterally beyond the locking housing (1) and, in a locked state of the horizontal locking bolt (7), engages in a lateral opening in the corner fitting (9) of the gooseneck container and secures the gooseneck container via the opening, and
the wedge slide (4) either
a) is mounted so that the wedge slide (4) can move back and forth in the horizontal direction of movement of the horizontal locking bolt (7) and is connected to the horizontal locking bolt (7),
or
b) is mounted so that the wedge slide (4) can move back and forth in a horizontal plane perpendicular to the direction of movement of the horizontal locking bolt (7) and the horizontal locking bolt (7) is operatively connected to the wedge slide (4) via a wedge drive (8).

A method for locking a container with a corner fitting (9) on a vehicle (F) with a container locking device adjustable between a locked state for locking the container on a loading surface (13) of the vehicle (F) and an unlocked state in which the container can be unloaded or loaded, comprising:

placing a container with a corner fitting (9) on a loading surface (13) of a vehicle (F), and
locking the container with the corner fitting (9) using a container locking device comprising a locking housing (1), a locking bolt (2) and a drive (3), wherein
the locking bolt (2) has a shaft (20) and a locking head (21) which, in an unlocked state of the locking bolt (2), can be the container inserted via an opening in the corner fitting (9) of the container and, in a locked state of the locking bolt (2), secures the container via projections engaging behind the opening of the corner fitting (9),
the locking bolt (2) with the shaft (20) is both axially displaceable in the locking housing (1) and rotatable about an axis of the locking bolt (2),
a wedge slide (4) in the locking housing (1) can be moved back and forth laterally by the drive (3), i.e. perpendicular to the axis of the locking bolt (2),
during the lateral movement of the wedge slide (4) by the drive (3) of the wedge slide (4), the locking bolt (2) first rotates axially by 90° when adjusting from the unlocked state to the locked state and then is lowered axially downwards towards the loading surface (13), and
when the locked state is reached, a spring-loaded safety lock (51) intrudes in the lateral movement path of the wedge slide (4) and the wedge slide (4) is prevented from being reset,
wherein simultaneously with the movement of the wedge slide (4), a horizontal locking bolt (7) in the locking housing (1) is displaced axially and horizontally, wherein the horizontal locking bolt (7) secures the gooseneck container in a loaded state of the gooseneck container arranged on the vehicle (F) with the corner fitting (9) of the gooseneck container horizontally adjacent and flush to the locking housing (1), engaging in a lateral opening in the corner fitting (9) of the gooseneck container and securing the gooseneck container.
