Abstract

Official abstract text for this publication.

A cleaning cart has a base plate and a working plate arranged at a vertical distance above the base plate, wherein the base plate and the working plate are connected to each other by a linkage arranged in the vertical distance. The linkage is formed by at least two struts extending non-parallel to each other.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cleaning cart, comprising: a base plate including a first outer boundary and a first fastening region having a first area; and a working plate including a second outer boundary and a second fastening region having a second area, the working plate being arranged at a vertical distance above the base plate, wherein the base plate and the working plate are connected to each other by a linkage arranged within the vertical distance, wherein the linkage includes first and second struts extending in a non-parallel manner with respect to each other, the first and second struts each having a first end-side end and a second end-side end opposite the first end-side end, wherein the first and second struts are in each case connected at the first end-side end of the strut to the first fastening region of the base plate, and in each case connected at the second end-side end of the strut to the second fastening region of the working plate, wherein the first area is smaller than the second area, and wherein the base plate includes a depositing area suitable for accommodating cleaning utensils inside the outer boundary of the respective plate and radially outside of the struts. 2. The cart of claim 1 , wherein the first end-side ends of the struts are at a first distance from each other, and the second end-side ends of the struts are at a second distance, and wherein the first distance is smaller than the second distance. 3. The cart of claim 1 , wherein the first and second struts are arranged trapezoidally with respect to each other, transversely with respect to a main travel direction of the cleaning cart. 4. 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. 5. The cart of claim 4 , 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 a main axis of accommodated struts is 1 to 3. 6. The cart of claim 1 , wherein the first and second struts are identical parts. 7. The cart of claim 1 , wherein the first and second struts each have a profile which is closed in a circumferential direction and does not include undercuts. 8. The cart of claim 1 , wherein the first and second struts each have a cross section differing from a circular shape. 9. The cart of claim 1 , wherein the first and second struts have an elliptical cross section, with a respective main axis which extends substantially in a main travel direction of the cleaning cart. 10. The cart of claim 9 , wherein main axes of the first and second struts arranged trapezoidally with respect to each other are arranged converging with respect to each other in a main travel direction. 11. The cart of claim 10 , wherein main axes of the first and second struts enclose an angle of 2° to 45° in a main travel direction. 12. The cart of claim 1 , wherein the working plate is larger than or the same size as the base plate, transversely with respect to a main travel direction. 13. The cart of claim 1 , wherein the first fastening region together with the first outer boundary bounds a depositing area for at least one cleaning utensil. 14. The cart of claim 13 , wherein the depositing area has a width of at least 50 mm. 15. The cart of claim 1 , wherein the base plate is larger than the working plate, transversely with respect to a main travel direction. 16. The cart of claim 1 , wherein the linkage includes no further strut beyond the first and second struts. 17. The cart of claim 1 , configured to accommodate elongated cleaning utensils extending from the working plate to the cleaning plate.
