DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0049] The exemplary embodiments described are merely examples which can be modified and/or supplemented in a variety of different ways in line with the claims. Any feature which has been described for a specific exemplary embodiment can be utilized on its own or in combination with other features in any other desired exemplary embodiment. Any feature which has been described for an exemplary embodiment of a certain category can also be used correspondingly in an exemplary embodiment from some other category.

[0050] FIG. 1 shows a schematic illustration of a system 10 comprising a mobile-foundation apparatus 12 and a parcel locker 14. The mobile-foundation apparatus 12, for its part, comprises, in turn, a mobile foundation 16, which in this exemplary embodiment is configured in the form of a concrete base 16, and a height-adjusting apparatus 18, which will be explained in more detail hereinbelow and by means of which the mobile foundation 16 can be adjusted in terms of height.

[0051] FIGS. 2 and 3 show sectional illustrations through the system 10 shown in FIG. 1, the sections being taken along the lines indicated by A and B in FIG. 1. It can be seen in FIGS. 2 and 3 that the height-adjusting apparatus 18 comprises a rod 20 with a threaded portion, which in the present exemplary embodiment extends over the entire length of the rod 20, a threaded plate 24, which is retained in an adjustable manner on the threaded portion and has a supporting surface 22, and a tube 28, which has a cavity 26. The tube 28 here is configured in the form of a rectangular tube 28 and has two mutually parallel outer sides 30a, 30b. On one of the outer sides 30a, the tube 28 comprises a wall aperture 32, through which the rod 20 projects into the cavity 26. The wall aperture 32 gives the rod 20 an amount of play, so that the rod 20 can be rotated relative to the tube 28 at least in part about an axis 34 parallel to the longitudinal axis of the tube 28. The axis of rotation 34 runs directly through the wall aperture 32 and, in FIG. 2, is located perpendicularly in relation to the drawing plane. Accordingly, the axis of rotation 34 in FIG. 2 is illustrated in the form of a circle with a cross in it. The rotary movement is indicated in FIGS. 2 and 3 by the arrow 36, wherein, in FIG. 2, the rod 20 performs a rotary movement in the drawing plane.

[0052] It can be seen in particular in FIG. 3 that the mobile foundation 16 additionally comprises an upper side 38 with a bearing surface 40 and comprises a bottom underside 42, which is located opposite the upper side 38. The parcel locker 14 is arranged on the bearing surface 40 and is connected, by means of threaded pins 44, to fastening means—in the present case threaded inserts with an internal thread—incorporated in the mobile foundation 16. The bearing surface 40 of the mobile foundation 16 is flanked on two sides by a vertical extension 46. The rear side of the parcel locker 14 is connected, by means of a further threaded pin 44, to the vertical extension 46, which butts against the rear side.

[0053] In order for the mobile foundation 16 to be connected to the height-adjusting apparatus 18, the mobile foundation 16 has openings 48, which run perpendicularly in relation to the bearing surface 40 and are continuous all the way to the underside 42. In the present case, the openings 48 run through the vertical extensions 46. As can be seen in particular in FIG. 2, the rod 20 of the height-adjusting apparatus 18 projects into the opening 48 of the mobile foundation 16 by way of an end which is directed away from the tube 28, wherein the supporting surface 22 of the threaded plate 24 is arranged on the underside 42 of the mobile foundation 16.

[0054] As can additionally be seen to good effect in FIGS. 2 and 3, the mobile foundation 16 has an aperture 50 in order for the threaded plate 24 to be mounted in a rotationally fixed manner on the underside 42, the aperture 50 establishing a form fit to prevent the threaded plate 24 from rotating relative to the mobile foundation 16. The mobile foundation 16 also has further apertures 52 in order for the tubes 28 to be incorporated in a recessed state on the underside 42 of the mobile foundation 16. As FIGS. 1 to 3 show, the further apertures 52 make it possible for the entire tube 28, which functions as a standing rail, to be accommodated in the further aperture 52, so that, in the state which is shown in FIGS. 1 to 3, a considerable proportion of the weight of the mobile foundation 16 is transferred, via the bottom underside 42, to the underlying surface. For this purpose, the further apertures 52 extend over the entire underside 42 of the mobile foundation 16. It is also the case that, in order for the threaded plate 24 to be mounted in a rotationally fixed manner, the apertures 50 are configured in the form of depressions in the further apertures 52. At the location of the depression, in addition, an overall height of the further aperture 52 and the depression 50 corresponds to the sum of a height of the tube 28 and a thickness of the threaded plate 24.

[0055] FIG. 4 shows a further schematic illustration of a further preferred embodiment of the mobile-foundation apparatus 12 comprising the mobile foundation 16 and the height-adjusting apparatus 18. In the case of this embodiment, the mobile foundation 16 has no vertical extensions on the upper side 38. Instead, the entire upper side 38 is formed by the bearing surface 40. FIG. 4 clearly illustrates, in particular, the height-adjusting function and inclination-compensating function of the height-adjusting apparatus 18. The position of the threaded plate 24 can be changed by rotation of the rod 20 about an axial extent axis 54 of the rod 20, which is illustrated symbolically by the arrow 56 in FIG. 4, this resulting in a change in the position of the underside 42 of the mobile foundation 16, the underside being arranged on the supporting surface 22. In the case of an inclined underlying surface, as illustrated in FIG. 4, the bearing surface 40 of the mobile foundation 16 can be horizontally adjusted, and the difference in level compensated for, via the height-adjusting apparatus 18.

[0056] In particular, it can be seen in FIG. 4 that, in the case of an inclined underlying surface, the rod 20, in relation to the two mutually parallel outer sides 30a, 30b of the tube 28, rests in a sloping state in the cavity 26 of the tube 28.

[0057] In addition, it can be seen schematically in the exemplary embodiment which is shown in FIG. 4 that the connection between the tube 28 and rod 20 is such that the rod 20 can be rotated relative to the tube 28 by 360 degrees about a further axis of rotation 58, which is illustrated by the arrow 60. The further axis of rotation 58 here runs through the wall aperture 32 of the tube 28 and parallel to a normal vector of the plane of the underlying surface.

[0058] Coming back to the exemplary embodiment which is shown in FIGS. 1 to 3, it can additionally be seen, in particular in FIGS. 2 and 3, that, at the end which is directed away from the tube 28, the rod 20 comprises a torque-transmission device 62 based on a form fit—in the present case a hole with a hexagon socket.
