a first vertical bar insert positioned between the first upper protrusion and the first lower protrusion; and
a second vertical bar insert positioned between the second upper protrusion and the second lower protrusion,
wherein the first and second vertical bar inserts have catching steps for securing door shelves to the first and second vertical bar inserts,
each of the first and second vertical bar inserts extending over a plurality of the catching steps,
the first vertical bar insert being closed at its ends by the first upper protrusion and the first lower protrusion,
the second vertical bar insert being closed at its ends by the second upper protrusion and the second lower protrusion,
the first and second vertical bar inserts each have an inner side surface, the inner side surface of the first vertical bar insert facing the inner side surface of the second vertical bar insert, and
wherein the catching steps are recesses in the inner side surfaces of the first and second vertical bar inserts.
2. The door as claimed in claim 1 , wherein the first vertical bar insert has a rear wall that rests against a first contact portion of the inner wall of the door, and second vertical bar insert has a rear wall that rests against a second contact portion of the inner wall of the door.
3. The door as claimed in claim 2 , wherein the rear walls of the first and second vertical bar inserts are aligned obliquely in relation to the outer wall of the door.
4. The door as claimed in claim 3 , wherein the first and second upper protrusions and the first and second lower protrusions protrude from a main surface of the inner wall farther than the rear walls protrude from the main surface.
5. The door as claimed in claim 3 , wherein the catching steps are L-shaped.
6. The door as claimed in claim 1 , wherein the catching steps are L-shaped.
7. A refrigerator door comprising:
an outer wall;
an inner wall, the inner and outer walls delimiting an intermediate space, the inner wall having:
a first upper protrusion,
a second upper protrusion,
a first lower protrusion, and
a second lower protrusion, the upper and lower protrusions being integrally molded parts of the inner wall;
a first vertical bar insert positioned between the first upper protrusion and the first lower protrusion; and
a second vertical bar insert positioned between the second upper protrusion and the second lower protrusion,
wherein the first and second vertical bar inserts have catching steps for securing door shelves to the first and second vertical bar inserts,
each of the first and second vertical bar inserts extending over a plurality of the catching steps,
each of the vertical bar inserts is an extruded profile formed of metal,
the first vertical bar insert being closed at its ends by the first upper protrusion and the first lower protrusion,
the second vertical bar insert being closed at its ends by the second upper protrusion and the second lower protrusion,
the first and second vertical bar inserts each have an inner side surface, the inner side surface of the first vertical bar insert facing the inner side surface of the second vertical bar insert, and
wherein the catching steps are recesses in the inner side surfaces of the first and second vertical bar inserts.
8. The refrigerator door as claimed in claim 7 , wherein the first and second vertical bar inserts are fastened to the inner wall by means of screws.
9. The refrigerator door as claimed in claim 8 , wherein the first and second vertical bar inserts each have a rear wall resting against the inner wall of the door, the first and second vertical bar inserts each have front wall, and the screws that fasten the first and second vertical bar inserts to the inner wall of the door penetrate the rear wall and are accessible through openings in the front wall.
10. The refrigerator door as claimed in claim 9 , wherein the rear walls of the first and second vertical bar inserts are aligned obliquely in relation to the outer wall of the door.
11. The refrigerator door as claimed in claim 7 , wherein each of the first and second vertical bar inserts is fastened to the inner wall by means of screws, each of which is positioned in threaded engagement with a respective backing piece accommodated in the intermediate space of the door.
12. The door as claimed in claim 11 , wherein each backing piece has limbs that protrude from the inner wall into the intermediate space delimited by the outer wall and the inner wall, and the limbs are embedded in an insulating material layer filling the intermediate space.
13. The door as claimed in claim 7 , wherein the first vertical bar insert has a rear wall that rests against a first contact portion of the inner wall of the door, and second vertical bar insert has a rear wall that rests against a second contact portion of the inner wall of the door.
14. The door as claimed in claim 13 , wherein the rear walls of the first and second vertical bar inserts are aligned obliquely in relation to the outer wall of the door.
15. The door as claimed in claim 14 , wherein the catching steps are L-shaped.
16. The door as claimed in claim 13 , wherein the first and second contact portions of the inner wall of the door protrude relative to other adjacent portions of the inner wall of the door.
17. The door as claimed in claim 16 , wherein the rear walls of the first and second vertical bar inserts are aligned obliquely in relation to the outer wall of the door.
18. The door as claimed in claim 16 , wherein the first and second upper protrusions and the first and second lower protrusions protrude from a main surface of the inner wall farther than the rear walls protrude from the main surface.
19. The door as claimed in claim 7 , wherein the catching steps are L-shaped.
20. The door as claimed in claim 19 , further comprising a shelf removably attached to the first and second vertical bar inserts, the shelf having:
an end face on each of two opposite sides of the shelf,
a recessed end region that is stepped in from each end face,
a step between each end face and its associated end region, and
a lug protruding from each recessed end region,
wherein each lug engages one of the catching steps, and each step rests on one of the first and second vertical bar inserts.
