DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] With reference firstly to FIG. 1 of the drawings, a safeguarding arrangement for restricting the movability of at least one transport container 17 storable or stored in a receptacle 16 of a support structure 14 is illustrated, the transport containers 17 of FIG. 1 being constituted by two half-size trolleys 18 arranged side by side in the receptacle 16 fitting flush with the support structure 14 in the area of a galley of an aircraft, not further shown here, as viewed in observation direction extending through the focal plane.

[0041] The safeguarding arrangement 10 has a safeguarding installation 11, comprising a first safeguarding means 12, the first safeguarding means 12 allows the transport containers 17 to be inserted into the receptacle 16 or to be retracted from the receptacle 16 via an opening 15, while in an open position.

[0042] Furthermore, the transport containers 17 are held in a hold position against removal from the receptacle 16 by the first safeguarding means 12, the safeguarding means 12 thereby overlaps a clean measure of the opening 15 of the receptacle 16, at least zonally, such that the safeguarding means 12 with a portion facing the outer of the two transport containers 17 in the hold position, shows such a small distance 26a with the transport container 17, that the two trolleys 18 are held securely in the receptacle 16. The external wall, indicated by a dashed line in FIG. 1, of the mentioned trolley 18 received in the receptacle 16 and facing the outside, fits flush with support structure 14 edging the opening 15 and just being covered by the trolley's wall in FIG. 1.

[0043] Such a configuration showing the safeguarding means 12 able to be swiveled about a swiveling axis 13 from an open position into a hold position is also known from the prior art.

[0044] Referring now to FIG. 2 of the drawings, the safeguarding means 10 according to the invention illustrated there shows structural similarity to the one shown in FIG. 1, but here, the first safeguarding means 12 is formed variable with regard to its engagement depth into the receptacle 16. The safeguarding arrangement 10 of FIG. 2 illustrates the transport container 17 in the form of a full-size trolley 19 received in the receptacle 16 and held by the safeguarding means 12 of the safeguarding arrangement 11 in the holding position.

[0045] The variability of the safeguarding means 12 shown in FIG. 2 results from its multipart configuration with a first holding part 20 and a second holding part 22. In addition, the safeguarding means is formed to be swiveled continuously between its open position and its hold position and it sweeps over a swivel range of about 90, which means a quarter turn of a full circle. For the sake of clarity, the fact that the first safeguarding means 12 is moveable against a spring force in the end positions being constituted by the open position and the hold position cannot be seen in FIG. 2.

[0046] However, one can clearly see that the first holding part 20 of the first safeguarding means 12 is, due to its shape, provided with a handle 21, at which it can be gripped and guided manually between the open position and the hold position, a fact depicted even better in FIGS. 3 and 4, described below.

[0047] Returning to the two holding parts 20, 22, one can see in FIGS. 2 to 4 that the first safeguarding means 12 is formed in a multipart manner with these holding parts 20 22, formed to be swiveled independent from one another about a common axis 13, which is represented by the swivel axis 13 mentioned before and which eccentrically extends through the holding parts 20, 22.

[0048] The two mentioned holding parts 20, 22 of the safeguarding means 12 comprise by this an essentially similar contour and cover one another in the same angular position, such that the second holding part 22 merely overlaps the first one in a partially circumferential peripheral zone 23, as arising again from FIGS. 3 and 4.

[0049] Further, it can be clearly recognized that the holding parts 20, 22 can be coupled, such as by frictional engagement, detents, and similar arrangements, that they are moveable synchronously, hence they can be swiveled. At this, the second holding part 22 comprises an edge 24 at its free end as a protruding portion, which edge projects into the receptacle 16 when the second holding part 22 and the coupled safeguarding means 12, respectively, are in the holding position, while its small distance or even its contact with the transport container 17 holds the latter in its position.

[0050] Accordingly, as can be clearly seen in FIG. 2, there exists no spacing, or a distance 26b falling below a predetermined maximum distance, between the edge 24 of the second holding part 22 in its holding position and a wall portion of the transport container 17 facing the edge 24 in the holding position.

[0051] Referring now to FIGS. 3 and 4, one recognizes that at first instance in FIG. 3, there is illustrated merely a securing installation 11 of the safeguarding arrangement 10 of FIG. 2. Firstly, one identifies the safeguarding means 12 of the safeguarding installation 10 with its two holding parts 20, 22 arranged to be swiveled jointly and synchronously and being situated jointly in the holding position, whereby the two holding parts 20, 22 are hence coupled and can be coupledly and synchronously moved, accordingly.

[0052] At this, the two holding parts 20, 22 are coupled via a coupling member 30, whose function is linked with the manner of the receptacle's 16 filling with trolleys, which additionally switches a switching element 32 of the coupling member 30. Due to insertion into the receptacle 16, which is not recognizable from FIG. 3, by a full-size trolley 19 representing the transport container 17, the switching element 32 is turned about its central axis by an amount of 90 using a mechanism not shown in detail for the sake of clarity. Thus, the switching element 32 performs a quarter turn such that the coupling member 30 provided with a bar-like actuation piece disengages from the slot 36 situated at the peripheral zone 23 of the second holding part 22. The coupling member 30 mechanically couples the holding parts 20, 22 to one another, whereas the coupling or decoupling of the holding parts 20, 22 is performed by moving of the coupling member 30 in the directions of the double arrow 38 between a release position shown in FIG. 3 and a locking position and vice versa, respectively.

[0053] The relevant locking position of the coupling member 30 may then be learned from FIG. 4, where the coupling member 30 is transferred along the direction of the arrow 39 in its locking position by the switching element 32, which has been switched in its other position turned about 90 by the insertion into the receptacle 16 of a half-size trolley 18 as the transport container 17. This, in turn, releases the coupling between the holding parts 20, 22, by which they are movable independently from one another. Through this, only the first holding part 20 moves into the holding position of the safeguarding means 12.

[0054] It can also be seen very clearly from FIG. 4 that the second holding part 22, which was not jointly moved into the holding position, comprises an edge 24 at its free end facing away from the swivel axis 13 forming a portion 25 protruding in the trolley insertion direction, which protrudes into the receptacle 16 when the second holding part 22 or the coupled safeguarding means 12, respectively, is in the holding position.

[0055] Moreover, one further recognizes a recess 28 provided with the support structure 14 in which the safeguarding means 12, especially the second holding part 22 of the safeguarding means 12, is stowable or stowed in the open position, at least partially. At this, at least the edge 24 is received in the recess 28 of the support structure 14 in the open position.

[0056] According to above explanations, the present disclosure pertains to a safeguarding arrangement 10 for restricting the movability of at least one transport container 17 storable or stored in a receptacle 16 of a support structure 14. The mentioned transport container 17 may be used for the transport of goods, for example, in an aircraft, and may be stowed in the area of the aircraft's galley as a so-called trolley 18, 19. The safeguarding arrangement 10 has a first safeguarding installation 11 with at least one first safeguarding means 12. The at least one first safeguarding means 12 allows the insertion or the removal of the at least one transport container 17 into the receptacle or from the receptacle, respectively, in its open position via an opening 15. At this, the safeguarding means 12 overlaps a clean measure of the opening 15 of the receptacle 16, at least zonally, in a hold position, in which the at least one transport container 17 is held against retraction from the receptacle 16.

[0057] Further, the first safeguarding means is formed variably with regard to its engagement depth into the receptacle 16.
