    [0045] In the figures, identical or functionally identical elements are provided with the same reference characters.

    [0046] In FIG. 1, a household refrigeration apparatus 1 is shown in a schematic representation, which can be a refrigerator or a freezer or a combined refrigerator-freezer. The household refrigeration apparatus 1, which is formed for storing and preserving food, comprises a housing 2, in which a first receiving space 3 for food and a second receiving space 4 for food separate thereto are formed in the shown embodiment. One of these two receiving spaces 3 and 4 can be a refrigerating compartment and the other one can be a freezing compartment. However, both receiving spaces 3, 4 can also be refrigerating compartments. Similarly, both receiving spaces 3, 4 can be freezing compartments.

    [0047] The receiving space 3 is disposed above the further receiving space 4 in height direction (y-direction). However, the two receiving spaces 3, 4 can also be disposed next to each other.

    [0048] Similarly, it is possible that one of the two receiving spaces 3, 4, for example the receiving space 3, is closed by two separate doors 5, 6, which are disposed next to each other in width direction (x-direction), and are disposed in the same or substantially the same height position to each other in height direction.

    [0049] The door 5 is pivotably disposed at the housing 2 around a vertically oriented rotational axis A. Similarly, the door 6 is disposed pivotably at the housing 2 around a vertically oriented rotational axis B.

    [0050] A horizontal gap 7 is formed between the two doors 5 and 6.

    [0051] Moreover, the household refrigeration apparatus 1 comprises hinges 8 and 9, by which the door 5 is pivotably supported at the housing 2. Correspondingly, it is provided that hinges 10 and 11 are provided, by which the door 6 is pivotably disposed at the housing 2.

    [0052] In FIG. 2, the hinge 8 is shown in an exemplary configuration. The hinge 8 comprises a base part 12, which is fixedly disposed at the housing. This base part 12 is also to be referred to as a bearing angle.

    [0053] Moreover, the hinge 8 comprises an in particular cylindrical pivot 13, which represents an adjusting part of the hinge 8. The pivot 13 is rotatably disposed on the base part 12. The door 5 is rotationally fixedly connected to the pivot 13.

    [0054] Moreover, the hinge 8 comprises a height adjusting device 14, which thus is formed integrated and thus integrally in the hinge 8. By means of the height adjusting device 14, the pivot 13 can be adjusted in its height position and thus in y-direction relative to the base part 12. Thereby, the door 5 is also correspondingly changed in its height position.

    [0055] The height adjusting device 14 is formed in discrete steps for changing the height position.

    [0056] The hinges 10 and 11 can also be correspondingly formed such that the door 6 is also adjustable in its height position.

    [0057] In FIG. 2, the assembled state between the base part 12 and the pivot 13 is shown.

    [0058] In FIG. 3, the hinge 8 is shown in an exploded view in a perspective partial representation, wherein the pivot 13 is here then removed from the base part 12, which is here only shown in certain areas. In the embodiment shown here, the pivot 13 is formed as a cylindrical part or pipe part. An upper pipe segment 15 is connected to a lower pipe segment 16. In particular, the pivot 13 is formed as an integral member. As is apparent in FIG. 3, the upper pipe segment 15 is formed with a larger radius than the lower pipe segment 16.

    [0059] In the implementation shown here, the lower pipe segment 16 plunges into a channel-like or duct-like receptacle 17 of the base part 12 in the assembled state as is shown in FIG. 2.

    [0060] As is moreover apparent in FIG. 3, the pivot 13 comprises an annular coupling disk 18, which is formed on the jacket wall of the pivot 13. This coupling disk 18 is a constituent of the height adjusting device 14. Here, the coupling disk 18 is preferably completely circumferentially formed.

    [0061] The base part 12 comprises a depression 19. In the assembled state, the coupling disk 18 can plunge therein. A coupling receptacle 20 of the height adjusting device 14 is integrally formed in this depression or recess 19. This coupling receptacle 20 is also configured as an annular area, which surrounds the duct-like receptacle 17 on the circumferential side at the upper end. The recess 19 can also be a constituent of the coupling receptacle 20.

    [0062] In FIG. 4, the integral pivot 13 according to a first embodiment is shown in an enlarged representation. As is apparent here, the coupling disk 18 comprises a first pedestal 22 on a bottom side 21, which faces the coupling receptacle 20 in the assembled state of the pivot 13. This first pedestal 22 is formed in the manner of a piece of cake and preferably formed in an angular interval with a circumferential extent between 20 and 70, in particular between 30 and 50, in circumferential direction around the axis A. As is apparent in FIG. 4, this first pedestal 22 extends raised to the bottom starting from the bottom side 21. This ii first pedestal 22 comprises a surface 23 spaced to the bottom side 21 in axial direction, which is preferably flatly formed and can also be regarded as the bottom side of the first pedestal 22 viewed in axial direction towards the bottom in this context. A coupling element 24 is formed on this surface 23 of the first pedestal 22. This coupling element 24 rises above this surface 23 and thus in axial direction towards the bottom in raised manner. This coupling element 24 is integrated in the first pedestal 22. In circumferential direction around the axis A, the coupling element 24 comprises ramp-like oblique flanks 25 and 26 on both sides. In the section in circumferential direction around the axis A, the coupling element 24 is trapezoidally or dome-like configured.

    [0063] As is moreover apparent, the coupling element 24 is formed substantially centrally on this bottom side 23. The bottom side 23 extends both in azimuthal direction around the axis A and in radial direction and thus perpendicular to the axis A respectively beyond the dimensions of the coupling element 24.

    [0064] Viewed in circumferential direction around the axis A, the height adjusting device 14 comprises a second pedestal 27 besides the already mentioned first pedestal 22 and the coupling element 24, which immediately adjoins to an edge side 28 of the first pedestal 22.

    [0065] This second pedestal 27 also rises from the bottom side 21 towards the bottom, but has a lower axial height in axial direction than the first pedestal 22, respectively viewed starting from the bottom side 21.

    [0066] The second pedestal 27 extends in a circumferential extent preferably between 20 and 70, in particular between 30 and 50, in circumferential direction around the axis A.

    [0067] The transitional flank 29 of the first pedestal 22, which joins to the second pedestal 27, is preferably also formed as an oblique flank.

    [0068] In particular, a terminating flank 30, which represents the end of the second pedestal 27 and faces away from the first pedestal 22, is also formed as an oblique flank, which then again joins to the bottom side 21.

    [0069] In an advantageous implementation, the second pedestal 27 is also a constituent of the height adjusting device 14.

    [0070] In the shown embodiment, it is provided that the first pedestal 22, the coupling element 24 and the second pedestal 27 are redundantly designed and duplicated in this respect. Here, it is in particular provided that the respectively mentioned partial elements in their duplicated design are offset to each other by 180 in circumferential direction around the axis A. This means, that a third pedestal 31 is here provided, which is offset to the second pedestal 27 by 180, but otherwise is correspondingly formed. Moreover, a fourth pedestal 32 is provided, which corresponds to the first pedestal 22 and is in particular identically formed with respect to the shaping and height configuration. This fourth pedestal 32 is also disposed offset to the first pedestal 22 by 180. The fourth pedestal 32 comprises a further coupling element 33, which is formed identical to the first coupling element 24 in shaping and position and disposed offset by 180 to the first coupling element 24.

    [0071] The surface 23, the surface 27a are flatly formed and thus the entire surfaces are each disposed in individual axial position. As is moreover apparent in FIG. 2 to 4, the coupling disk 18 comprises a plurality of separate receptacles 35 on its jacket wall 34, which are formed as insertion holes. Thereby, it can be engaged by an auxiliary tool 36 (FIG. 2) and a rotational movement of the pivot 13 around the rotational axis A relative to the base part 12 can be effected.

    [0072] In FIG. 5, the partial area of the base part 12, as it is also apparent in FIG. 3, is shown in an enlarged representation. As is apparent here, a staircase profile 37 of the coupling receptacle 20 surrounding the rotational axis at least in certain areas is integrally formed on a surface of the coupling receptacle 20 facing the coupling disk 18. This staircase profile 37 comprises a first step or first staircase 38 and a further staircase 39 directly adjoining thereto viewed in circumferential direction of the axis A, which is a staircase located at higher level in axial direction. A third staircase 40 is formed directly adjoining to the second staircase 39 again viewed in circumferential direction of the axis A, which is again located at higher level than the second staircase 39.

    [0073] In the shown embodiment, the staircase profile 37 extends around a circumferential extent of 180 around the axis A. Here, it is provided that this staircase profile 37 too is implicitly and thus redundantly designed. This means that the three staircases 38, 39 and 40 are again formed, wherein subsequent to the uppermost or highest staircase 40, a deepest or first staircase 37 is then again formed directly adjoining. Viewed in circumferential direction around the axis A, a second staircase 38 then again follows and a highest third staircase 39 again adjoining thereto, which then again directly adjoins to the first, deepest staircase 38 of the primary staircase profile 37.

    [0074] The staircases 38, 39 and 40 each comprise contact surfaces 38a, 39a and 40a, which are preferably each flat and horizontal (oriented perpendicular to the axis A). Receiving depressions 41, 42 and 43 are respectively formed in these contact surfaces 38a, 39a and 40a. A coupling element, in particular the coupling element 24, plunges into these receiving depressions 41 to 43. If a first, lowest height position of the pivot 13 to the base part 12 is adjusted, thus, the coupling element 24 is locked in the receiving depression 41. If a second discrete height position is adjusted, which is higher than this first height position, thus, the coupling element 24 is locked in the receiving depression 42. Moreover, if the coupling element 24 is locked in the receiving depression 43, the third, discrete and highest height position of the pivot 13 relative to the base part 12 is adjusted. The door 5 is then also correspondingly adjustable in the three different height positions here to be exemplarily understood.

    [0075] The further coupling element 33 then respectively correspondingly and complementarily plunges into the respectively other receiving depressions of the staircases 38 to 40 of the redundantly formed staircase or the staircase profile 37.

    [0076] Advantageously, it is provided that bounding walls of a receiving depression 41, 42, 43 viewed in circumferential direction around the axis A are obliquely and/or rounded formed. This is exemplarily shown by the bounding walls 42a and 42b in FIG. 5 with respect to the receiving depression 42. Thereby, a continuous and simpler sliding in as well as sliding out of the coupling element 24 from this receiving depression 42 is allowed. In an advantageous implementation, it can be provided that the oblique flanks 25 and 26 are adapted to the shaping of the bounding walls 42a and 42b such that a form-fit abutment over the entire surface area of these mentioned walls is substantially achieved in this respect.

    [0077] As is moreover apparent, the depression 19 is formed with such an axial depth that the coupling disk 18 is disposed completely recessed in the recess 19 in the assembled state as it is shown in FIG. 2.

    [0078] In FIG. 6, the base part 12 is shown in the area of the coupling receptacle 20 in a top view. A staircase profile 37 with its three staircases 38, 39 and 40 to be exemplarily understood here extends around a circumferential extent of 180. Here, the staircases 38, 39 and 40 form a discretely rising staircase profile and thus represent a section of a spiral staircase.

    [0079] As is apparent in FIG. 6 in the top view, the recess 19 is formed with a larger radius over a partial segment in circumferential direction around the axis A than in a further other area different thereto. This area 44 with the larger radius extends around a circumferential extent preferably between 50 and 120. As is moreover apparent in FIG. 6, an integrated web 45 as well as a further integrated web 46 are formed in this radially wider area, which each comprise oblique flanks 47 and 48. Therein, the web 45 is formed on a top side or contact surface 39a on a second staircase of the implied staircase profile 37. The further web 46 spaced thereto in circumferential direction is formed on the contact surface 40a of the staircase 40. The webs 45 and 46 preferably extend in radial direction only over the dimensions, over which the radially expanded area 44 radially extends beyond the other area of the recess 19.

    [0080] In this respect, it is provided in an advantageous implementation that the pivot 13, as it is shown in FIG. 4, comprises a radial coupling element 49, which can then couple to these webs 45 and 46.

    [0081] In FIG. 7, a top view to the representation in FIG. 6 is shown, wherein the pivot 13 according to FIG. 4 is here inserted in the recess 19 such that the coupling disk 18 is received in the recess 19 and the height adjusting device 14 is coupled. This means that the pedestals 22, 27, 31 and 32 as well as the coupling elements 24 and 33 are coupled to the staircase profiles 37.

    [0082] By this radial coupling element 49, a stop can also be formed such that the maximum capability of rotation of the pivot 13 around the rotational axis A can also be limited by the circumferential extent of the radially expanded area 44. In FIG. 7, it is shown how this radial coupling element 49 abuts on a first stop wall 50 of the radially expanded area 44. A further stop wall 51 of this radially expanded area 44 is shown opposing.

    [0083] In FIG. 8, the configuration according to FIG. 7 is shown in a sectional representation along the sectional line VIII-VIII in FIG. 7. Here, it is apparent how the coupling element 24 is locked in the receiving depression 41. Moreover, it is also apparent that the top side 23 of the first pedestal 22 rests on the contact surface 38a, and how the top side 27a of the second pedestal 27 rest on the next higher step 39 and there on the contact surface 39a.

    [0084] In FIG. 9, a further embodiment of a pivot 13 is shown. In contrast to the configuration of FIG. 4, here, the lower pipe segment 16 is not present. Thus, the coupling disk 18 here represents the lower termination of the pivot 13 in axial direction.

    [0085] In FIG. 10, the base part 12 is partially shown in a further embodiment in a perspective representation. In contrast to the implementation according to FIG. 5 and FIG. 6, here, it is provided that a cylindrical element 53 in particular protruding from the recess 19 is integrally formed, to which the pivot 13 according to FIG. 9 can then be fitted. In this context with regard to the coupling of the pivot 13 to the base part 12, an inverse configuration compared to the examples according to FIG. 3 to FIG. 8 is shown.

    [0086] In the example in FIG. 9 and FIG. 10, the remaining configuration of the height adjusting device 14 is corresponding as in the embodiment according to FIG. 2 to FIG. 8.
