Abstract

In an embodiment, the present invention provides a torsion wringer including: a contraction device for receiving a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base. A reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part.

First claim

The invention claimed is:

1. A torsion wringer comprising:
a contraction device configured to receive a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base,
wherein a reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part.

2. The torsion wringer according to claim 1 , wherein the distance of travel is in the range of from 1 cm to 20 cm, and the angle of rotation is in the range of from 5° to 180°.

3. The torsion wringer according to claim 2 , wherein the distance of travel is in the range of from 3 cm to 8 cm.

4. The torsion wringer according to claim 3 , wherein the distance of travel is in the range of from 3 cm to 5 cm.

5. The torsion wringer according to claim 1 , wherein the reduction unit comprises at least one spring element which is operatively connected to the contraction device such that said element is configured to push the contraction device into its starting position counter to the reciprocating force.

6. The torsion wringer according to claim 1 , wherein the reduction unit comprises spring lamellae arranged on the carrier device, which spring lamellae are configured to push the contraction lamellae radially inwards when the contraction device is moved relative to the carrier device.

7. The torsion wringer according to claim 6 , wherein at least one spring lamella of the spring lamellae has a first leg which is hinged to a collar of the carrier device, and a second leg hinged to a support base of the carrier device.

8. The torsion wringer according to claim 6 , wherein at least one spring lamella of the spring lamellae comprises at least one stop lug.

9. The torsion wringer according to claim 6 , further comprising a traction cable which is fastened at one end to a spring lamella of the spring lamellae or a support base and at its other end to a collar of the carrier device.

10. The torsion wringer according to claim 1 , wherein the contraction lamellae extend from the upper part of the contraction device to the lower base of the contraction device, the lower base remaining rotationally fixed when the upper part is moved relative to the carrier device.

11. The torsion wringer according to claim 1 , wherein the contraction lamellae are arranged so as to be inclined with respect to the lower base of the contraction device, the contraction lamellae being configured to bend radially inwards in regions when the upper part is moved relative to the carrier device.

12. The torsion wringer according to claim 1 , wherein the lower base of the contraction device is configured to be locked into a spring-mounted support base of the carrier device.

13. The torsion wringer according to claim 1 , wherein a mounting device is provided on the carrier device, the mounting device being configured to stably mount a handle of the mop.

14. The torsion wringer according to claim 1 , wherein support elements configured to prevent deformation of a bucket are arranged on the carrier device.

15. A set comprising a torsion wringer and a bucket;
the torsion wringer comprising:
a contraction device configured to receive a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base,
wherein a reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part;

wherein the torsion wringer is interlockingly connected to the bucket.

16. A torsion wringer comprising:
a contraction device configured to receive a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base,
wherein a reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part, and
wherein the contraction device comprises on the upper part thereof guide cams which are in engagement with guides which are associated with the carrier device.

17. The torsion wringer according to claim 16 , wherein a guide comprises a curved or inclined groove in which a guide cam is configured to be guided.

18. The torsion wringer according to claim 17 , wherein the groove is inclined with respect to the horizontal by a slot angle which is in the range of from 20° to 89°.

19. A torsion wringer comprising:
a contraction device configured to receive a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base,
wherein a reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part, and
wherein the contraction lamellae extend from the upper part of the contraction device to the lower base of the contraction device, a contraction lamella of the contraction lamellae being hinged to the upper part by a pivot element, and the pivot element being configured to bend radially inwards when the upper part is moved relative to the carrier device and relative to the lower base.

20. The torsion wringer according to claim 19 , wherein the pivot element comprises a curved portion with a circular segment shape.
