The functionality of the door hinge 30 or the adjusting device 39 will be explained in summary below. With the help of the adjusting device 39, the first door 3 can be adjusted so that the first design and functional gap 17 can be adjusted. The same applies to the second door 8 and the corresponding second design and function gap 18. However, only the first door 3 will be discussed below.

To set the door 3, the cover caps 27, 28 are first removed from the door profiles 23, 24. As a result, the engagement portion 53 of the eccentric 50 and the engagement portion 55 of the locking member 54 are easily accessible. Subsequently, the locking element 54 is loosened. By means of a twisting of the eccentric element 50, the contact region 41 can now be moved in the longitudinal direction z due to the contact of the eccentric section 52 with the side wall 42 of the adjustment element 40. As a result, the corresponding door profile 23, 24 is displaced along the longitudinal direction z or against it. In addition, when the eccentric portion 52 of the eccentric element 50 is in contact with one of the side walls 43, 45, the corresponding contact area 47, 48 can also be moved in the transverse direction y. As a result, the door 3 is additionally lent to the door hinge 30 braced. As a result, a backlash of the door 3 can be achieved.

After adjustment of the eccentric element 50, the adjusting element 40 is locked again by means of the locking element 54 on the hinge arm 33. In this case, for example, on the rear side, that is to say facing the hinge arm 33, a particularly high surface roughness can be provided on the base 46, which prevents undesired adjustment of the adjustment element 40 along the longitudinal direction z. After fixing the

Locking element 54, the cover caps 27, 28 are pushed back into the openings 25, 26 of the door profiles 23, 24.

With the help of the adjusting device 39 is thus a simple and quick adjustability of the design and function gaps 17, 18 possible. On the hinge arm 33, only the two holes 37, 38 must be mounted for the installation of the adjusting device 39. This means that existing hinge arms 33 can be used or simply retrofitted.

The axis of rotation 66 includes an engagement portion 68, which may be formed, for example, as a slot. The axis of rotation 66 is rotatably disposed in the slots 64 provided in the side walls 60, 61. The eccentric member 65 is positioned between the end portion 35 of the hinge arm 33 and the side wall 59 of the adjustment member 58.

Furthermore, the adjusting device 56 also comprises a locking element 54 as already explained above. The locking element 54 is, as mentioned above, preferably a screw which is screwed into the bore 57 of the hinge arm 33. The functionality of the adjusting device 56 essentially corresponds to the functionality of the adjusting device 39 explained with reference to FIGS. 2 to 7. First, the covering caps 27, 28 are removed from the openings 25, 26 of the door profiles 23, 24. Subsequently, the locking element 54 is released and the eccentric 65 is actuated, wherein the eccentric portion

67 inside against the side wall 59 presses. As shown in FIGS. 10 to 13, the contact portion 41 can be displaced along the hinge arm 33 by rotating the eccentric member 65 in the longitudinal direction y. Here, FIGS. 10 and 11 show a minimal possible displacement of the contact region 41, and FIG. 13 shows a maximum possible displacement of the contact region 41. FIG. 12 shows an intermediate position.
