Locking device for fastening a container
A locking device for fastening containers for an aircraft. The locking device comprises at least one locking arrangement that can be affixed to an aircraft floor and that comprises a retaining element. The locking arrangement can be fastened to the aircraft floor such that a gap for adjusting the container is provided between the container and the locking arrangement. The retaining element of the locking arrangement can subsequently be moved in the direction of the payload such that a gap between the locking arrangement and the payload can be adjusted.
1. A locking device for fastening a container in an aircraft, the locking device comprising:
at least one locking arrangement comprising a retaining element;
wherein the at least one locking arrangement is attachable to an aircraft floor such that a gap for adjusting the container is provided between the container and the at least one locking arrangement;
wherein the retaining element of the at least one locking arrangement is adapted for moving in the direction of the container such that the gap between the at least one locking arrangement and the container is adjustable;
wherein the retaining element comprises an eccentric detent element with engaging teeth and an engaging element; and
wherein the detent element is adapted to be inserted in the gap, and the position of the detent element is adapted to be locked into place in that the engaging teeth of the detent element engage the engaging element.
2. The locking device of claim 1 , wherein the retaining element comprises a threaded rod for adjusting the gap.
3. The locking device of claim 1 , wherein the engaging element comprises a foot lever for locking the detent element into place.
4. The locking device of claim 1 , further comprising a fastening rail with adjustment holes, which fastening rail is affixed to the aircraft floor; and
wherein the at least one locking arrangement is adapted to be adjustably affixed in a defined position along the fastening rail to provide the gap between the container and the at least one locking arrangement.
5. The locking device of claim 1 , further comprising at least one damping element affixed between the retaining element and the container to dampen movements of the container.
6. The locking device of claim 1 , further comprising an inspection element;
wherein the inspection element is designed such that in the case of a malfunction of the at least one locking device an indication signal is generated.
7. The locking device of claim 1 , wherein the at least one locking arrangement is a plurality of locking arrangements with retaining elements;
wherein the plurality of locking arrangements enclose the container in such a way that the gap for adjusting the container is provided; and
wherein the retaining elements of the plurality of locking arrangements are adapted for moving in the direction of the container such that the gap between the plurality of locking arrangements and the container is adjustable.
8. A method for fastening a container in an aircraft, comprising:
affixing at least one locking arrangement with a retaining element to an aircraft floor;
wherein the at least one locking arrangement is fastened to the aircraft floor such that a gap for adjusting the container is provided between the container and the at least one locking arrangement;
wherein the retaining element of the at least one locking arrangement moves in the direction of the container such that the gap between the at least one locking arrangement and the container is adjustable;
inserting the retaining element into the gap with an eccentric detent element with engaging teeth; and
fixing the position of the detent element in the gap by engagement of an engaging element with the engaging teeth.
9. The method of claim 8 , further comprising:
damping a movement of the container by a damping element attached between the retaining element and the container.
10. The method of claim 8 , further comprising:
monitoring the at least one locking arrangement by an inspection element with electrical sensors; and
generating an indication signal in the case of malfunction of a locking device.
11. The method of claim 8 , wherein the at least one locking arrangement is a plurality of locking arrangements with retaining elements, further comprising:
locking in the container by the plurality of locking arrangements with retaining elements in such a way that the gap for adjusting the container is provided between the plurality of locking arrangements and the container; and
setting the gap between the plurality of locking arrangements and the container by the retaining elements that are adapted for moving in the direction of the container.
12. An aircraft comprising a locking device for fastening a container, the locking device comprising:
at least one locking arrangement comprising a retaining element;
wherein the at least one locking arrangement is attachable to an aircraft floor such that a gap for adjusting the container is provided between the container and the at least one locking arrangement;
wherein the retaining element of the at least one locking arrangement is adapted for moving in the direction of the container such that the gap between the at least one locking arrangement and the container is adjustable;
wherein the retaining element comprises an eccentric detent element with engaging teeth and an engaging element; and
wherein the detent element is adapted to be inserted in the gap, and the position of the detent element is adapted to be locked into place in that the engaging teeth of the detent element engage the engaging element.
