Abstract

A cleaning tool for a floor cleaning machine is proposed which includes a cleaning-action device and a supporting part on which the cleaning-action device is arranged and by means of which the cleaning tool is fixable to the floor cleaning machine, wherein the supporting part includes a seating having a wall and a seating space for a tool holding head of the floor cleaning machine which is bounded by the wall, and the wall includes a holding region for the tool holding head, wherein the wall includes an insertion region for the tool holding head to which the holding region is adjoined, wherein the seating space is widened in the insertion region in comparison with the holding region and tapers towards the holding region.

First claim

1 . A cleaning tool for a floor cleaning machine comprising:
a cleaning-action device and a supporting part on which the cleaning-action device is arranged and by means of which the cleaning tool is fixable to the floor cleaning machine; wherein the supporting part comprises a seating having a wall and a seating space for a tool holding head of the floor cleaning machine which is bounded by the wall, and the wall comprises a holding region for the tool holding head; wherein the wall comprises an insertion region for the tool holding head to which the holding region is adjoined; and wherein the seating space is widened in the insertion region in comparison with the holding region and tapers towards the holding region.

2 . The cleaning tool in accordance with claim 1 , wherein the seating space tapers continuously in the insertion region in a direction towards the holding region.

3 . The cleaning tool in accordance with claim 1 , wherein the seating space is of greater diameter in the insertion region than in the holding region.

4 . The cleaning tool in accordance with claim 1 , wherein the insertion region is arranged in the seating space before the holding region taken with reference to an insertion direction of the tool holding head.

5 . The cleaning tool in accordance with any claim 1 , wherein a wall region which defines the insertion region is oriented at an obtuse angle to a wall region which defines the holding region.

6 . The cleaning tool in accordance with claim 5 , wherein the obtuse angle lies in a range of between 120° and 160°.

7 . The cleaning tool in accordance with claim 1 , wherein, with regard to an envelope thereof, an inner surface of the holding region facing the seating space is cylindrical.

8 . The cleaning tool in accordance with claim 1 , wherein, with regard to an envelope thereof, an inner surface of the insertion region facing the seating space is in the form of a frustum of a cone.

9 . The cleaning tool in accordance with claim 1 , wherein the wall is in the form of a ring.

10 . The cleaning tool in accordance with claim 1 , wherein the wall has a cylindrical outer surface.

11 . The cleaning tool in accordance with claim 1 , wherein the supporting part extends in an axial direction with an axial axis which coincides with a rotational axis of the cleaning tool.

12 . The cleaning tool in accordance with claim 1 , wherein one or more sub-regions of the wall protrude beyond a flange.

13 . The cleaning tool in accordance with claim 1 , wherein a plurality of spaced ribs are arranged on an inner surface of the wall at least in the holding region, wherein a mating element of the tool holding head is insertable into a space between spaced ribs.

14 . The cleaning tool in accordance with claim 13 , wherein the ribs are oriented in an axial direction and are spaced in a circumferential direction.

15 . The cleaning tool in accordance with claim 13 , wherein the ribs have an upper surface which is oriented at an acute angle to an axial direction.

16 . The cleaning tool in accordance with claim 15 , wherein the upper surface is arranged at least partly in the insertion region.

17 . The cleaning tool in accordance with claim 13 , wherein a rib comprises a tapering region towards a spaced rib in which a width of the rib in the direction of spacing from the neighboring rib reduces in a direction towards the insertion region.

18 . The cleaning tool in accordance with claim 17 , wherein a sloping surface serving as an insertion aid for a mating element of the tool holding head is formed in the tapering region.

19 . The cleaning tool in accordance with claim 1 , wherein a locating element for the tool holding head in an axial direction is arranged on the supporting part.

20 . The cleaning tool in accordance with claim 1 , wherein at least one meshing element for the tool holding head is arranged on the supporting part for axial fixing purposes.

21 . The cleaning tool in accordance with claim 20 , wherein at least one meshing element is arranged on a locating element for the tool holding head.

22 . The cleaning tool in accordance with claim 20 , wherein the at least one meshing element is seated on the supporting part in moveable manner and is latchable to the tool holding head.

23 . The cleaning tool in accordance with claim 1 , wherein the supporting part is formed in one piece manner.

24 . The cleaning tool in accordance with claim 1 , said cleaning tool being in the form of a brushing tool.

25 . A floor cleaning machine comprising at least one tool holding head to which a cleaning tool is fixable or is fixed in releasable manner, said cleaning tool comprising:
a cleaning-action device and a supporting part on which the cleaning-action device is arranged and by means of which the cleaning tool is fixable to the floor cleaning machine; wherein the supporting part comprises a seating having a wall and a seating space for a tool holding head of the floor cleaning machine which is bounded by the wall, and the wall comprises a holding region for the tool holding head; wherein the wall comprises an insertion region for the tool holding head to which the holding region is adjoined; and wherein the seating space is widened in the insertion region in comparison with the holding region and tapers towards the holding region.

26 . The floor cleaning machine in accordance with claim 25 , wherein the tool holding head is driven or is drivable in rotary manner.

27 . The floor cleaning machine in accordance with claim 25 , wherein the at least one tool holding head is moveable in a height direction taken with respect to a substrate on which the floor cleaning machine is placed.

28 . The floor cleaning machine in accordance with claim 25 , wherein the at least one tool holding head comprises a plurality of spaced grooves on an outer surface thereof, wherein a respective mating element is formed between each of the neighboring grooves, and ribs of the supporting part of the cleaning tool are insertable into the grooves and the mating element is insertable into a space between neighboring ribs of the supporting part.

29 . The floor cleaning machine in accordance with claim 25 , wherein the at least one tool holding head comprises at least one recess for a meshing element of the cleaning tool for the purpose of the axial fixing thereof.
