Abstract

A holder for securing mop at the end of a handle, in which a plurality of relatively moveable, absorbent strips made of a textile material are affixed as a result of being clamped between a headpiece and a plate, essentially at right angles to the longitudinal axis of the handle. In the region where the strips are fastened, the holder has a surface area having a length greater than its width, and boundary edges of which are curved to form two corners, without changing the direction of the curvature.

Claims

1. A holder for securing a mop to an end of a handle, the mop including a plurality of relatively movable and absorbent strips of a textile material, the holder comprising:

a headpiece including at least two edge regions configured to cooperate with the strips, a ratio of a length of the headpiece to a width of the headpiece being between 1.2 and 4; and

plate, the strips being clampingly engageable between the headpiece and the plate;

wherein the edge regions extend in a direction of a longitudinal axis of the holder, each of the edge regions having a radius of curvature that is between 0.61 and 4.25 times the width of the headpiece, the radius of curvature being one of the following;

a) a constant radius of curvature, and

b) a sectionally changing radius of curvature.

2. The holder according to claim 1, wherein the strips are clampingly engageable between the headpiece and the plate at an angular displacement relative to each other.

3. The holder according to claim 1, wherein strips are clampingly engageable between the headpiece and the plate substantially at a right angle to a longitudinal axis of the handle.

4. The holder according to claim 1, wherein the ratio of the length of the headpiece to the width of the headpiece is greater than 1.6.

5. The holder according to claim 1, wherein the edge regions define at least two corners disposed at ends of the headpiece bordering the length of the headpiece.

6. The holder according to claim 1, wherein the edge regions define a flattened region at each end of the headpiece bordering the length of the headpiece, the flattened region preventing acute-angled corners.

7. The holder according to claim 2, wherein corners are disposed outside of ends of the headpiece bordering the length of the headpiece.

8. The holder according to claim 1, wherein each edge region includes at least one circular segment.

9. The holder according to claim 1, wherein, in the region that strips are clampingly engageable, the holder is in mirror symmetry about the longitudinal axis of the holder.

10. The holder according to claim 1, wherein the radius of curvature of a first one of the edge regions is greater than the radius of curvature of a second one of the edge regions.

11. The holder according to claim 1, wherein an angle formed between tangents to ends of the headpiece bordering the length of the headpiece is less than or equal to 90°

.

12. The holder according to claim 1, wherein the edge regions are curved downwardly toward corners thereof in a three-dimensional manner.

13. The holder according to claim 1, further comprising:

a tilting joint connecting the holder to the handle, the tilting joint configured to permit the handle to be tilted in the direction of the longitudinal axis of the holder.

14. The holder according to claim 10, further comprising:

an arrangement configured to restrict a tilting angle between a vertical to the longitudinal axis of the holder to ±

60°

with respect to the vertical.

15. The holder according to claim 14, wherein the arrangement is configured to restrict the tilting angle to ±

25°

with respect to the vertical.

16. The holder according to claim 1, wherein a surface area of the plate is greater than a surface area of the headpiece.

17. The holder according to claim 1, wherein at least one of the headpiece and the plate is dome-shaped.

18. The holder according to claim 17, wherein the at least one of the headpiece and the plate is concave.

19. The holder according to claim 17, wherein an edge is formed at an intersection of dome-shaped partial sections of the at least one of the headpiece and the plate.

20. The holder according to claim 1, wherein corners of the holder are rounded with a radius between 0.05 times the width and 0.25 times the width.

21. The holder according to claim 1, wherein the ratio of the length to the width is less than or equal to 2.4 and a ratio of the radius of curvature to the width is less than or equal to 3.38.
