Good to see here is also that the recess 43 in the bending of the rail element, which serves the tilt adjustment, is made wider in both the height and in the lateral direction than the diameter of the adjusting screw 33 in the region of the groove. This allows the coupling in the adjustment direction of the adjusting screw 33 a relative movement transversely to their adjustment both in the height direction and in the width direction of the door.

The height adjustment is again in FIG. 11 shown. To adjust the height, the screws 23 of the zero position were unscrewed from the domes 4 and the bores 14 on the door-side fastening element and 37 on the adjusting element 30. Furthermore, the fastening screws 23, which connect the adjusting element 30 with the appliance door, loosened. As a result, a displacement of the door-side fastening element in the height and in the width direction is possible. The adjustment in the vertical direction is effected by turning the adjusting screw 31, which thereby causes an adjusting movement along its longitudinal axis between the door-side fastening element and the adjusting element 30. Since the adjusting element 30 is still fixed on the appliance door by means of the screws 23, this causes an adjustment movement of the appliance door relative to the door-side fastening element.

The width adjustment is in FIG. 12 shown in more detail. Again, the screws 21 of the zero position were removed and the mounting screws 23 loosened. The width adjustment is carried out by turning the adjusting screws 32, which thereby produce an adjustment along its longitudinal direction. The adjusting movement in turn takes place between the adjusting element 30 and the door-side fastening element 10. Since the adjusting element is fixed by the fastening screws 23 on the appliance door, this in turn results in an adjustment of the appliance door in the width direction relative to the door-side fastening element. In this case, two adjusting screws 32 are provided with a certain vertical distance to the adjusting element. As a result, on the one hand, a certain tilting is made possible when needed. For a uniform adjustment in the width direction, however, the two adjusting screws 32 are each rotated identically.

Since the door-side fastening element in the height and width direction of the rail-side fastening element, on this on the pull-out rail and is determined by this on the body of the household appliance, results from the adjustment of the door to the door-side fastener an adjustment of the door in the height and width direction relative to the body of the household appliance.

After height or width adjustment, the fastening screws 23 are tightened again, which thereby press the adjustment 30 on the connecting portion 11 of the door-side fastener and the door, so that all elements are fixed to each other.

In FIG. 14c Finally, the screw is shown, which passes through the holes 14 and 44 and thus provides the defined zero position according to the present invention.

In zero position while the screws 17, 18 and 14 are tightened. To adjust the tilt adjustment, the screw 14 must first be removed, while the screws 17 and 18 are slightly loosened. Now a tilt adjustment by turning the adjusting screw 33 is possible. This generates a linear adjustment movement in its longitudinal direction, which is converted by the distance to the rotation axis 17 in a rotational movement between the rail side and the door-side fastener. The adjusting movement initially takes place between the rail-side fastening element and the adjusting element 30, in which the adjusting screw 33 is screwed. Since the adjusting element 30 is fixed to the door-side fastening element takes place As a result, a twist of door-side and rail-side fastener, which in turn has a tilt adjustment of the door result.

According to the invention, the screw of the zero position, which was unscrewed from the holes 14 and 44, are screwed through the slot 22 on the door-side fastener into the bore 42 on the rail-side fastener. This can be z. B. done before a tilt adjustment is made. As a result, the screw for zeroing can not be lost. After adjusting the adjusting all screws are now tightened again to set the rail-side fastener on the door-side fastener.

In FIG. 15 now a door 70 is shown, which has been attached via door connections to pull-out rails 50 of a household appliance. In this case, a stand 80 is provided, which extends along the inner door 1 of the left pull-out rail to the right pull-out rail and is supported on this. The stand 80 has in each case on its underside a left and a right receptacle 81, with which it has been pushed over the door connections. In this case, the receptacles receive the components of the door connection arranged above the pull-out rail, in particular the components of a rail-side fastening element and a door-side fastening element and an adjusting device arranged above the pull-out rail. As a result, they are arranged protected and the risk of injury from protruding sharp components is reduced. The door connection is covered from above and from the side completely by the supporter. The door rack additionally serves to stabilize the door connection.
