Abstract

A cleaning cart having a base plate and a working plate arranged at a vertical distance above the base plate, the base plate and the working plate being connected to each other by a rod system arranged within the vertical distance. The rod system is formed by at least two struts extending in a non-parallel manner relative to each other, and the struts are connected to each other by a bridge-like holder, the holder being arranged in a self-retaining manner between the struts.

First claim

The invention claimed is:

1. A cleaning cart, comprising:
a base plate;
a working plate arranged at a vertical distance above the base plate; and
a linkage connecting the base plate to the working plate, the linkage disposed within the vertical distance,
wherein the linkage includes a first and a second strut, extending in a non-parallel manner with respect to each other,
wherein the first and second struts are connected to each other by a rack-shaped holder, and
wherein the holder is arranged in a self-locking manner, wedged between the first and second struts.

2. The cart of claim 1 , wherein the struts are in each case connected at a first end-side end to a first fastening region of the base plate and in each case at a second end-side end to a second fastening region of the working plate.

3. The cart of claim 2 , wherein the first fastening region includes a first area and the second fastening region includes a second area, and
wherein the first area is smaller than the second area.

4. The cart of claim 2 , wherein the first end-side ends of the struts are at a first distance from each other, and
wherein the second end-side ends of the struts are at a second distance, and
wherein the first distance is smaller than the second distance.

5. The cart of claim 1 , wherein the struts are arranged trapezoidally with respect to each other, from a front and/or rear elevational view colinear with a main travel direction of the cleaning cart.

6. The cart of claim 1 , wherein the end-side ends are arranged in a frictional and/or form-fitting manner in respective recesses of the base plate and/or of the working plate.

7. The cart of claim 1 , wherein all of the struts are designed as identical parts.

8. The cart of claim 1 , wherein the struts each have a profile which is closed in the circumferential direction and does not have undercuts.

9. The cart of claim 1 , wherein the struts each have a cross section differing from the circular shape.

10. The cart of claim 1 , wherein the struts have an elliptical profile, with a respective main axis which extends substantially in a main travel direction of the cleaning cart.

11. The cart of claim 10 , wherein the main axes of the struts arranged trapezoidally with respect to each other are arranged converging with respect to each other downwardly, from a front elevational view colinear with the main travel direction.

12. The cart of claim 11 , wherein the main axes enclose an angle of 2° to 45° in the main travel direction.

13. The cart of claim 6 , wherein the recesses have a depth, and
wherein a ratio of the depth of the recesses, in which corresponding struts are accommodated, to a length of the main axis of the struts is 1 to 3.

14. The cart of claim 1 , wherein the base plate and the working plate respectively include an outer boundary.

15. The cart of claim 1 , wherein the base plate is designed to be larger than the working plate, viewed perpendicular to a main travel direction of the cleaning cart.

16. The cart of claim 2 , wherein a relatively smaller first fastening region together with an outer boundary of a relatively larger base plate bounds a depositing area for cleaning utensils.

17. The cart of claim 16 , wherein the depositing area has a width of at least 50 mm.

18. The cart of claim 1 , wherein the holder is arranged substantially parallel to the base plate and to the working plate.

19. The cart of claim 1 , wherein the holder includes a respective holding clip on end sides on both sides, with which the holder is secured on corresponding struts.

20. The cart of claim 19 , wherein the holding clips each include two half shells which are connected to each other by a joint, and
wherein the half shells together enclose the corresponding struts in a manner bearing there against on an outer circumferential side.

21. The cart of claim 20 , wherein the joint is formed by a film hinge.

22. The cart of claim 1 , wherein the holder includes a respective shelf on the end sides, and
wherein the respective shelf is designed congruently with respect to a profile of corresponding strut and is supported on the strut.

23. The cart of claim 1 , wherein the holder includes receiving devices for cleaning utensils.

24. The cart of claim 23 , wherein the receiving devices are connected in a frictional and/or form-fitting manner to the holder.

25. The cart of claim 23 , wherein the receiving devices are of hook-shaped design.

26. The cart of claim 1 , wherein the holder and/or holding clips, included on end sides of the holder on both sides, and/or receiving devices, included on the holder for cleaning utensils, include a polymeric material.

27. The cart of claim 2 , wherein the first fastening region includes a first area and the second fastening region includes a second area, and
wherein the second area is smaller than the first area.

28. The cart of claim 2 , wherein the first end-side ends of the struts are at a first distance from each other, and
wherein the second end-side ends of the struts are at a second distance, and
wherein the second distance is smaller than the first distance.

29. The cart of claim 1 , wherein the base plate is designed the same size as the working plate, viewed perpendicular to a main travel direction of the cleaning cart.

30. The cart of claim 1 , wherein the working plate is designed to be larger than the base plate, viewed perpendicular to a main travel direction of the cleaning cart.

31. The cart of claim 1 , wherein the working plate is designed to be the same size as the base plate, viewed perpendicular to a main travel direction of the cleaning cart.

32. The cart of claim 2 , wherein a relatively smaller second fastening region together with an outer boundary of a relatively larger working plate bounds a depositing area for cleaning utensils.

33. A cleaning cart, comprising:
a base plate;
a working plate arranged at a vertical distance above the base plate; and
a linkage connecting the base plate to the working plate, the linkage disposed within the vertical distance,
wherein the linkage includes a first and a second strut, extending in a non-parallel manner with respect to each other,
wherein the first and second struts are connected to each other by a rack-shaped holder, and
wherein the holder is arranged in a self-locking manner between the first and second struts,
wherein the struts are in each case connected at a first end-side end to a first fastening region of the base plate and in each case at a second end-side end to a second fastening region of the working plate,
wherein the first fastening region includes a first area and the second fastening region includes a second area, and
wherein the first area is smaller than the second area.

34. A cleaning cart, comprising:
a base plate;
a working plate arranged at a vertical distance above the base plate; and
a linkage connecting the base plate to the working plate, the linkage disposed within the vertical distance,
wherein the linkage includes a first and a second strut, extending in a non-parallel manner with respect to each other,
wherein the first and second struts are connected to each other by a rack-shaped holder, and
wherein the holder is arranged in a self-locking m
