Abstract

A cleaning system comprising a hand-guided cleaning cart having rollers that is movable over a supporting surface, for transporting and storing cleaning utensils for manual cleaning is provided. The cleaning system also has at least one receiving device arranged along the cleaning cart and two or more different functional devices for operation and/or use of the at least one cleaning cart. The functional devices are selectively connectable to the at least one receiving device, such that the at least one receiving device and the functional devices may be considered cooperating connecting elements.

First claim

What is claimed is:

1. Cleaning system comprising a hand-guided cleaning cart which comprises rollers and is movable over a supporting surface, for transporting and storing cleaning utensils for manual cleaning, wherein the cleaning system comprises at least one receiving device arranged at the cleaning cart and two or more different functional devices for at least one of operation and use of the cleaning system, wherein the functional devices are selectively connectable to the at least one receiving device, wherein the at least one receiving device and the functional devices comprise cooperating connecting elements, wherein at least one of the functional devices comprises a coupling device for coupling the cleaning cart to a further cleaning cart of the cleaning system, and wherein the cleaning system comprises at least one further cleaning cart which comprises a receiving device and a functional device in the form of a coupling device which is connected to the receiving device of the further cleaning cart, and wherein the cleaning carts are connectable together via the intercoupling coupling devices.

2. Cleaning system in accordance with claim 1 , wherein the cleaning system comprises at least one of more than two different functional devices and a plurality of identically configured functional devices.

3. Cleaning system in accordance with claim 1 , wherein the cleaning system comprises two or more cleaning carts, and wherein at least one receiving device is arranged at the respective cleaning cart, wherein at least one of the functional devices is selectively connectable to a receiving device of one of the cleaning carts.

4. Cleaning system in accordance with claim 1 , wherein the functional devices comprise at least one handle device having at least one element for the user.

5. Cleaning system in accordance with claim 4 , wherein at least one of the following applies:
a handle device is provided in which the at least one handle element is arranged at the functional device in a non-movable manner;
a handle device is provided in which the at least one handle element is adapted to be moved relative to a base element comprised by the handle device.

6. Cleaning system in accordance with claim 5 , wherein the at least one movable handle element is pivotable about a pivot axis relative to the base element, which pivot axis is oriented parallel to a contact plane of the cleaning cart defined by the rollers.

7. Cleaning system in accordance with claim 6 , wherein the handle device comprises or forms a securing device for securing the handle element against movement relative to the base element.

8. Cleaning system in accordance with claim 4 , wherein at least one of the following is provided:
a handle device is provided in which the at least one handle element is oriented in a plane parallel to a contact plane of the cleaning cart defined by the rollers;
a handle device is provided in which the at least one handle element is oriented in a plane transverse to a contact plane of the cleaning cart defined by the rollers.

9. Cleaning system in accordance with claim 1 , wherein at least one of the coupling devices and the receiving devices of the two cleaning carts are of identical configuration.

10. Cleaning system in accordance with claim 1 , wherein the cleaning system comprises at least one clamping holder for cleaning utensils which has an elastically deformable holding part that can be transferred from a holding position in which it at least partially engages behind the cleaning utensil to an expanded release position in which the cleaning utensil is removable from the clamping holder and insertable therein.

11. Cleaning system in accordance with claim 10 , wherein the at least one clamping holder is fixed or fixable to at least one of the at least one functional device and the at least one receiving device, at least one of the at least one functional device and the at least one receiving device comprising at least one fixing device for fixing the at least one clamping holder.

12. Cleaning system in accordance with claim 11 , wherein the at least one clamping holder is releasably connectable to at least one of the at least one functional device and the at least one receiving device via the at least one fixing device.

13. Cleaning system in accordance with claim 11 , wherein the fixing device and a projection arranged at the at least one clamping holder are configured to connect together in a push-and-twist type connection, wherein the projection is insertable in the fixing device in an insertion direction and lockable to the fixing device by rotation about an axis oriented in the insertion direction.

14. Cleaning system in accordance with claim 12 , wherein the fixing device is arranged at the at least one functional device which comprises a base element having at least one through-opening, and wherein the holding part, in the state of being fixed to the fixing device, and the fixing device are arranged on sides of the base element that face away from each other, and wherein the projection extends through the through-opening.

15. Cleaning system in accordance with claim 12 , wherein the at least one receiving device comprises or forms at least one recess in which the fixing device engages in a connection state of the at least one functional device to the receiving device.

16. Cleaning system in accordance with claim 1 , wherein the cleaning system comprises at least one holding part for cleaning utensils, which holding part has at least one hook element for suspending the cleaning utensil therefrom, wherein the at least one holding part is fixable to the cleaning cart via at least one functional device.

17. Cleaning system in accordance with claim 16 , wherein the at least one holding part, with at least one holding section thereof, engages in a recess which is formed between the at least one functional device assuming a connection state and the cleaning cart, and wherein the holding part is hangingly fixed to at least one of the functional device and the receiving device via the at least one holding section.

18. Cleaning system in accordance with claim 1 , wherein the cleaning system comprises at least one cover device which is connectable to the receiving device and which covers connecting elements arranged at the receiving device.

19. Cleaning system in accordance with claim 18 , wherein the at least one cover device does not project beyond an outer contour of the cleaning cart and/or wherein the cover device aligns with an outer contour of the cleaning cart.

20. Cleaning system in accordance with claim 1 , wherein at least one of the functional devices and at least one cover device which is connectable to the receiving device and which covers connecting elements arranged at the receiving device is releasably connectable to the at least one receiving device.

21. Cleaning system in accordance with claim 1 , wherein at least one of the functional devices comprises at least one blocking element by way of which the functional device is secured to the receiving device against release therefrom when the blocking element assumes a blocking position, and is releasable from the receiving device when the blocking element assumes a release position.

22. Cleaning system in accordance with claim 1 , wherein two or more functional devices comprise connecting elements of identical configuration.

23. Cleaning system in accordance claim 1 , wherein the functional devices each comprise a ba
