wherein the retaining element comprises a stop for resting against a pivotable locking lug of a locking device such that the locking lug holds the retaining element in the operative position thereof, wherein the stop is pivotally mounted at the retaining element such that the retaining element can be pivoted from a stop position of the stop into a lowering position of the stop, wherein the stop protrudes beyond the retaining element in the stop position of the stop along the longitudinal direction.
2. The cargo gate according to claim 1 , wherein the stop is pivotable by means of a stop articulation from the stop position into the lowering position.
3. The cargo gate according to claim 2 , including at least one spring element which preloads the stop into the lowering position.
4. The cargo gate according to claim 1 wherein the articulation for pivoting the retaining element from the operative position thereof into the inoperative position comprises a pivot articulation which defines a rotational axis.
5. The cargo gate according to claim 4 wherein the stop protrudes beyond the retaining element in the stop position in a direction parallel to the rotational axis.
6. The cargo gate according to claim 1 , wherein the fastening device comprises a holding device, the holding device comprising a holding slide for fastening in a perforated rail and/or seat rail of the cargo hold.
7. A cargo deck of an aircraft which extends along an X-direction and a Y-direction, comprising:
at least one cargo gate with at least one retaining element,
at least one fastening device having at least one articulation for articulatedly fastening the retaining element to a cargo hold floor of the cargo deck such that the retaining element can be pivoted from an operative position for holding at least one cargo item into an inoperative position, wherein the retaining element can be traversed by the at least one cargo item in the inoperative position, the retaining element having a stop,
at least one locking device having a locking lug which is pivotable from an operative position of the locking lug into a loading position, wherein the cargo gate is arranged in such a way that, in the operative position of the retaining element, the stop of the retaining element of the cargo gate rests against the locking lug in order to hold the retaining element in the operative position thereof, wherein the locking device comprises at least one pneumatic or electrical actuator for actuating the locking lug remotely.
8. A cargo deck of an aircraft which extends along an X-direction and a Y-direction, comprising:
at least one cargo gate with at least one retaining element,
at least one fastening device having at least one articulation for articulatedly fastening the retaining element to a cargo hold floor of the cargo deck such that the retaining element can be pivoted from an operative position for holding at least one cargo item into an inoperative position, wherein the retaining element can be traversed by the at least one cargo item in the inoperative position, the retaining element having a stop,
a plurality of locking devices having a locking lug which is pivotable from an operative position of the locking lug into a loading position, wherein the cargo gate is arranged in such a way that, in the operative position of the retaining element, the stop of the retaining element of the cargo gate engages the locking lug in order to hold the retaining element in the operative position thereof,
at least one side guide running along the X-direction of the cargo deck for holding and guiding cargo items, wherein the locking devices are arranged in such a way that the locking lugs protrude into a guiding region of the side guide;
fixing points for fixing the at least one cargo gate in at least a first and a second position, wherein for each position at least one of the locking devices is arranged such that the locking lug of the respective locking device engages the stop of the at least one cargo gate in the operative position of the retaining element.
9. The cargo deck according to claim 7 wherein the locking device comprises an adjusting mechanism for remotely controlled electrical and/or pneumatic actuation.
10. A cargo deck of an aircraft which extends along an X-direction and a Y-direction, comprising:
at least one cargo gate with at least one retaining element,
at least one fastening device having at least one articulation for articulatedly fastening the retaining element to a cargo hold floor of the cargo deck such that the retaining element can be pivoted from an operative position for holding at least one cargo item into an inoperative position, wherein the retaining element can be traversed by the at least one cargo item in the inoperative position, the retaining element having a stop,
at least one locking device having a locking lug which is pivotable from an operative position of the locking lug into a loading position, wherein the cargo gate is arranged in such a way that, in the operative position of the retaining element, the stop of the retaining element of the cargo gate rests against the locking lug in order to hold the retaining element in the operative position thereof wherein the locking device comprises an adjusting mechanism configured in such a way that the locking device can be brought into at least three states, namely:
a loading state, in which the locking lug is in the loading position,
a holding state, in which the locking lug is in the operative position thereof and is fixed, and
a release state, in which the locking lug is in the operative position thereof but can then be pivoted from the operative position of the locking lug into the loading position if a force acting on the locking lug exerted by the stop of the retaining element exceeds a predetermined amount.
11. The cargo deck according to claim 10 , wherein the adjusting mechanism comprises a spring assembly which defines the predetermined amount of the force (F) acting in the X-direction.
12. The cargo deck according to claim 11 , wherein the spring assembly comprises a tensioning device which, in particular, is electromotively adjustable, for adjusting a preload of a retention clip.
13. The cargo deck according to claim 7 wherein the retaining element comprises recesses to accommodate functional elements attached on the cargo deck in the inoperative position.
