Shaft for a cleaning tool and a cleaning tool provided with such a shaft

1 . A telescopic shaft for a cleaning tool, comprising:

a first shaft portion for fastening of a cleaning tool thereto,

a second shaft portion which is slidably connected to the first shaft portion, and

a spraying device for distributing a liquid cleaning agent, the spraying device comprising a first fastening element which defines a passage extending in a longitudinal direction (L),

wherein the second shaft portion has, over at least part of its length, a cross section with a non-circular outer shape,

wherein the spraying device is removably connected to the second shaft portion, the second shaft portion is-being rotatable about a longitudinal axis (A) of the second shaft portion with respect to the first shaft portion and with respect to the spraying device fastened thereto, and

wherein the second shaft portion extends in the longitudinal direction (L) through the passage, such that the spraying device is connected to the second shaft portion, and wherein the second shaft portion is rotatable about its longitudinal axis (A) in the passage.

2 . The telescopic shaft for a cleaning tool according to claim 1 , wherein the telescopic shaft comprises a blocking device with a non-blocking state, in which the first and the second shaft portions are slidable with respect to each other in their longitudinal direction, and a blocking state, in which the first and the second shaft portions are retained in a fixed mutual position with respect to each other, and wherein the blocking device can be brought from the non-blocking state to the blocking state, and vice versa, by an axial rotation of the first and the second portions with respect to each other.

3 . The telescopic shaft for a cleaning tool according to claim 2 , wherein the blocking device comprises a movable retaining element which is connected to one of the first and the second shaft portions and which has a friction surface, the movable retaining element for placing the friction surface against a surface of another of the first and the second shaft portions when the blocking device is in the blocking state, such that the first and the second shaft portions are retained by friction with respect to each other.

4 . The telescopic shaft for a cleaning tool according to claim 1 , wherein a part of the second shaft portion which is located in a passage has an outer shape with a non-circular cross section, wherein the passage is laterally delimited by a cylindrical wall of a first fastening element, a diameter of the wall being at least approximately equal to a diameter of the circle described around the non-circular cross section of the second shaft portion, such that the second shaft portion can rotate about its longitudinal axis (A) in the passage.

5 . The telescopic shaft for a cleaning tool according to claim 1 , wherein the spraying device is fastened to the first shaft portion by a second fastening element, wherein the first shaft portion is connected to the spraying device in a rotationally fixed manner.

6 . The telescopic shaft for a cleaning tool according to claim 1 , wherein the second shaft portion has, over at least part of its length, an oval or tri-oval outer shape.

7 . The telescopic shaft for a cleaning tool according to claim 1 , wherein an end piece is fastened to the upper end of the telescopic shaft, and wherein the end piece is rotatable with respect to the telescopic shaft about an axis which virtually coincides with the longitudinal axis (A) of the shaft, and wherein the telescopic shaft comprises a mechanism to place the end piece in a rotatable state or a non-rotatable state as desired.

8 . The telescopic shaft for a cleaning tool according to claim 1 , wherein the first shaft portion comprises two virtually rectilinear end pieces which adjoin each other by way of a curve.

9 . A cleaning tool, wherein the cleaning tool is connected to a telescopic shaft according to claim 1 .

10 . The cleaning tool according to claim 9 ,

wherein the cleaning tool is a cleaning tool for cleaning a surface.

11 . The cleaning tool according to claim 10 , wherein the cleaning tool is a floor mop, a brush, or a floor wiper.

12 . A telescopic shaft for a cleaning tool, comprising:

a first shaft portion for fastening of a cleaning tool thereto,

a second shaft portion which is slidably connected to the first shaft portion, and

a spraying device for distributing a liquid cleaning agent,

wherein the second shaft portion has, over at least part of its length, a cross section with a non-circular outer shape,

wherein the spraying device is removably connected to the second shaft portion, the second shaft portion being rotatable about a longitudinal axis (A) of the second shaft portion with respect to the first shaft portion and with respect to the spraying device fastened thereto,

wherein a first fastening element comprises an access opening, which extends over the length of a passage, in the lateral delimitation of the passage, wherein the passage is laterally accessible via the access opening, such that the second shaft portion can be brought, in a position in which its longitudinal axis (A) is substantially parallel to a longitudinal direction (L) of the first fastening element, into the passage via the access opening in order to connect the spraying device to the second shaft portion.
