Abstract

A mop cover has a planar main body with four outer edges, wherein a longer first outer edge is oriented parallel to a longer second outer edge, the first outer edge being longer than the second outer edge, two shorter outer edges respectively extending between the longer outer edges, the main body having at least two pockets, into which mop wings or tensioning elements can be introduced to tense the planar main body, being configured such that the mop cover can be readily gripped, and tensioned, by rectangular wings, wherein the mop cover can be guided effectively for cleaning purposes with the greatest possible degrees of freedom in corner regions, a mop cover of the type mentioned in the introduction is characterized in that at least one outer edge and/or at least one pocket are/is assigned at least one stiffening element for the partially reinforced stiffening of the main body.

First claim

The invention claimed is:

1. A mop cover, comprising:
a planar main body including a first, second, third, and fourth outer edge,
wherein the first outer edge is longer than other outer edges and oriented in parallel with the second, also longer, outer edge, the first outer edge being longer than the second outer edge,
wherein the third and fourth outer edges, which are shorter than the first and second outer edges, each extend between the first and second outer edges,
wherein the main body further includes a first and a second pocket, configured such that, one or more wings or tensioning elements of a mop can be inserted into the pockets in order to stretch out the planar main body,
wherein at least one of the outer edges and/or pockets includes at least one stiffening element, configured to provide increased stiffening to regions of the main body.

2. The cover of claim 1 , wherein the at least one stiffening element makes the main body stable in a region adjoining either the first or the second pocket such that the main body retains its geometric shape in a self-supporting manner in this region, even if the one or more wings having a rectangular free end is received in the pocket or if the one or more wings not having a trapezoidal free end is received therein.

3. The cover of claim 1 , wherein the stiffening element is produced or shaped from a synthetic sheet or from a plastic sheet.

4. The cover of claim 1 , wherein the stiffening element completely overlaps at least the first or the second pocket.

5. The cover of claim 1 , wherein the stiffening element partially overlaps at least the first or the second pocket.

6. The cover of claim 1 , wherein the stiffening element is strip-shaped, runs along either the first or second outer edge, and extends as far as to a corner region of the first or second outer edge which a shorter outer edge joins.

7. The cover of claim 1 , wherein the at least one stiffening element comprises two stiffening elements, and
wherein the two stiffening elements are opposite one another in mirror image with respect to an axis of symmetry.

8. A mop, comprising:
the mop cover of claim 1 ; and
a first and a second wing, which wings can pivot relative to one another and each include a rectangular free end.

9. The cover of claim 1 , wherein at least one of the outer edges includes the at least one stiffening element.

10. The cover of claim 9 , wherein the at least one stiffening element comprises a first stiffening element, the first stiffening element being the at least one stiffening element included with the at least one of the outer edges, and a second stiffening element, and
wherein at least one of the pockets includes the second stiffening element.

11. The cover of claim 1 , wherein at least one of the pockets includes the at least one stiffening element.

12. The cover of claim 1 , wherein the at least one stiffening element comprises a plurality of stiffening elements, and
wherein two or more of the outer edges each include one of the plurality of stiffening elements.

13. The cover of claim 12 , wherein two or more of the pockets each include one of the plurality of stiffening elements.

14. The cover of claim 1 , wherein the at least one stiffening element comprises a plurality of stiffening elements, and
wherein two or more of the pockets each include one of the plurality of stiffening elements.

15. The cover of claim 1 , wherein the stiffening element includes a synthetic.

16. The cover of claim 1 , wherein the stiffening element includes a plastic.

17. The cover of claim 1 , wherein the stiffening element includes a sheet including a synthetic.

18. The cover of claim 1 , wherein the stiffening element includes a sheet including a plastic.
