Abstract

An uncoupling mat includes a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side. The annular cavities on the bottom side each define a recess on the first side. The indentations have a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations. A plurality of weakening zones each extends between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones.

First claim

I claim:

1. An uncoupling mat, comprising:
a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side, the annular cavities on the bottom side each defining a recess in a middle thereof on the first side,
the indentations having a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations,
a plurality of weakening zones, each extending between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones,
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, and
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.

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

3. The uncoupling mat according to claim 1 , wherein the at least some of the first group of weakening zones are formed in bottom portions of the indentations.

4. The uncoupling mat according to claim 3 , wherein the indentations extend beneath a heating cable when a heating cable is held within the indentations.

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

6. The uncoupling mat according to claim 1 , wherein each recess is formed in a middle of each annular cavity.

7. The uncoupling mat according to claim 1 , wherein the first and second groups of weakening zones cross each other at right angles.

8. An uncoupling mat, comprising:
a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side, the annular cavities on the bottom side each defining a recess in a middle thereof on the first side,
the indentations having a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations,
a plurality of weakening zones, each extending between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones,
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, and
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; and wherein
the weakening zones are formed in bottom portions of the indentations such that the indentations extend beneath a heating cable when a heating cable is held within the indentations.
