Abstract

An uncoupling mat ( 1 ) includes a flexible plastic layer ( 2 ) made of a film-like plastic with structuring that defines indentations ( 6 ) provided with undercuts ( 5 ) on the first side ( 4 ) and cavities ( 8 ) positioned between the indentations ( 6 ) on the opposite second side ( 7 ). A fleece or fabric ( 3 ) is securely connected to the second side ( 7 ) and covers the cavities ( 8 ). The plastic layer ( 2 ) is provided with a plurality of weakening zones ( 12 ) which extend continuously between opposing side edges of the plastic layer ( 2 ).

First claim

I claim:

1. An uncoupling mat ( 1 ), comprising:
a flexible plastic layer ( 2 ) made of a film-like plastic with structuring that defines indentations ( 6 ) provided with undercuts ( 5 ) on a first, top side ( 4 ) and cavities ( 8 ) positioned between the indentations ( 6 ) on an opposite second, bottom side ( 7 ), and
a fleece or fabric ( 3 ) securely connected to the second side ( 7 ) and covering the cavities ( 8 )
the plastic layer including a plurality of weakening zones ( 12 ) which each extend between two rows of indentations ( 6 ) in a straight line and continuously between opposing side edges of the plastic layer ( 2 ) and allow the plastic layer ( 2 ) to move substantially transversely to the direction of extension of the weakening zones; wherein
a cross-section of the indentations ( 6 ) in at least some corner regions ( 10 ) increases towards the first, top side ( 4 ) from the second, bottom side ( 7 ) of the corresponding indentation ( 6 ).

2. The uncoupling mat ( 1 ) according to claim 1 , wherein the weakening zones ( 12 ) comprise grooves.

3. The uncoupling mat ( 1 ) according to claim 1 , wherein the plastic layer ( 2 ) has a substantially constant thickness (d), a thickness in the weakening zones being smaller than the thickness (d).

4. The uncoupling mat ( 1 ) according to claim 1 , wherein at least some of a first group of weakening zones ( 12 ) extend parallel to one another, said parallel weakening zones extending transversely to a longitudinal direction of the uncoupling mat ( 1 ).

5. The uncoupling mat ( 1 ) according to claim 4 , wherein at least some of a second group of weakening zones ( 12 ) extend parallel to one another, the second group of parallel weakening zones crossing the first group of parallel weakening zones at right angles.

6. The uncoupling mat ( 1 ) according to claim 1 , wherein the weakening zones ( 12 ) are arranged spaced apart from one another equally at distances being in the range of from 10 to 100 mm.

7. The uncoupling mat ( 1 ) according to claim 6 , wherein the weakening zones ( 12 ) are spaced at distances being in the range of from 10 to 50 mm.

8. The uncoupling mat ( 1 ) according to claim 1 , wherein the fleece of fabric ( 3 ) has through holes ( 13 ) with a cross-section in the range of from 0.5 to 1.0 mm 2 .

9. The uncoupling mat ( 1 ) according to claim 8 , wherein the through holes ( 13 ) include a cross-section in the range of from 0.5 to 0.8 mm 2 .

10. The uncoupling mat according to claim 1 , wherein the cavities ( 8 ) cross one another and define a grid- or net-like arrangement.

11. The uncoupling mat according to claim 1 , wherein the indentations ( 6 ) cross one another and define a grid- or net-like arrangement.

12. The uncoupling mat according to claim 11 , wherein the mat includes 100 to 3000 cavities ( 8 ) per square meter.

13. The uncoupling mat ( 1 ) according to claim 12 , wherein the cavities ( 8 ) at least partially have an annular cross-section.

14. The uncoupling mat ( 1 ) according to claim 13 , wherein the indentations ( 6 ) have a minimum width (B min ) in the range of from 3 to 20 mm.

15. The uncoupling mat ( 1 ) according to claim 1 , wherein the indentations ( 6 ) have a minimum width (B min ) in the range of from 3 to 20 mm and a maximum height (H max ) in the range of from 2 to 20 mm.

16. The uncoupling mat according to claim 1 , wherein at least some of a first group of weakening zones extend parallel to one another, said parallel weakening zones extending transversely to a longitudinal direction of the uncoupling mat.

17. The uncoupling mat according to claim 4 , wherein at least some of a second group of weakening zones extend parallel to one another, the second group of parallel weakening zones crossing the first group of parallel weakening zones at right angles.

18. An uncoupling mat ( 1 ), comprising:
a flexible plastic layer made of a film-like plastic with structuring that defines indentations provided with undercuts on the first, top side and cavities positioned between the indentations on the opposite second, bottom side;
a fleece or fabric securely connected to the second side and covering the cavities;
the plastic layer including a plurality of weakening zones which each extend between two rows of indentations in a straight line and continuously between opposing side edges of the plastic layer and allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones; and
the plastic layer having a substantially constant thickness, with a thickness in the region of the weakening zones being smaller than the substantially constant thickness.

19. The uncoupling mat according to claim 18 , wherein
a cross-section of the indentations in at least some corner regions increases towards the top side from the bottom side of the corresponding indentation.

20. An uncoupling mat, comprising:
a flexible plastic layer made of a film-like plastic with structuring extending down from a top surface of the film-like plastic that define indentations provided with undercuts on a first, top side and cavities positioned between the indentations on an opposite second, bottom side;
a fleece or fabric securely connected to the second side and covering the cavities;
the plastic layer including a plurality of weakening zones formed in the top surface of the film-like plastic, which each extend between two rows of indentations in a straight line and continuously between opposing side edges of the plastic layer and allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones;
at least some of a first group of weakening zones extend parallel to one another across the top surface of the film-like plastic, said parallel weakening zones extending transversely to a longitudinal direction of the uncoupling mat; and
at least some of a second group of weakening zones extend parallel to one another across the top surface of the film-like plastic, the second group of parallel weakening zones intersecting the first group of parallel weakening zones at right angles.
