Abstract

A floor element for forming a floor covering, wherein the floor element comprises a decorative layer made of a ceramic material; a support layer arranged below the decorative layer; and a reinforcing layer arranged in between the decorative layer and the support layer, wherein the support layer comprises edges provided with coupling elements configured to realize a mechanical coupling with coupling elements of an adjacent floor element.

Claims (42)

1 . A floor element for forming a floor covering, the floor element comprising:

a decorative layer made of a ceramic material;

a support layer arranged below the decorative layer, the support layer comprising a rigid polyvinylchloride (PVC), wherein the rigid PVC comprises less than 15 phr of plasticizer; and

a reinforcing layer located between the decorative layer and the support layer,

wherein the support layer comprises edges provided with coupling elements configured to realize a mechanical coupling with coupling elements of an adjacent floor element,

wherein the coupling elements comprise at least one male part and at least one female part,

wherein in a coupled condition of adjacent floor elements, locking surfaces are formed limiting the mutual movement of the adjacent floor elements in at least in a vertical direction,

wherein the male part protrudes outwardly beyond an upper edge of the decorative layer and the female part extends inwardly beyond an upper edge of the decorative layer to thereby form an undercut underneath the decorative layer so that the locking surfaces limiting the movement in the vertical direction are at least formed by a top surface of the male part and an upper surface of the undercut formed by the female part,

wherein the upper surface of the undercut is a bottom surface of the decorative layer delimiting the undercut in an upward direction,

wherein the floor element has an impact strength greater than 1.91 Newton-meter (Nm),

wherein in a coupled condition of the adjacent floor elements, the locking surfaces are formed, limiting the mutual movement of the adjacent floor elements in at least one horizontal direction,

wherein in a coupled condition of the adjacent floor elements, first locking surfaces are formed limiting the mutual movement of the adjacent floor elements in a horizontal direction along the coupled edges, as well as second locking surfaces limiting the mutual movement of the adjacent floor elements in a direction that is substantially horizontal and perpendicular to the coupled edges, and

wherein the locking surfaces comprise portions positioned on resilient arms.

2 . The floor element according to claim 1 , wherein the reinforcing layer comprises a fiberglass layer or a fiberglass mat.

3 . The floor element according to claim 1 , wherein the reinforcing layer comprises a metal plate with a coefficient of thermal expansion higher than the coefficient of thermal expansion of the decorative layer.

4 . The floor element according to claim 1 , wherein the decorative layer has a thickness between 4 and 15 mm.

5 . The floor element according to claim 1 , wherein the floor element has a thickness of 13 mm or less.

6 . The floor element according to claim 1 , wherein the decorative layer comprises a brittle material and/or comprises natural stone, glass, or concrete.

7 . The floor element according to claim 1 , wherein the support layer further comprises fiber cement.

8 . The floor element according to claim 1 , wherein the coupling elements are configured to realize the coupling by means of a translational downward motion of the floor element with respect to the adjacent floor element.

9 . The floor element according to claim 1 , wherein the male part is in the form of a tongue and the female part is in the form of a groove, or wherein the male part and the female part are dovetail shaped in a top plane view.

10 . The floor element according to claim 1 , wherein the decorative layer is mounted on the support layer in such a way that, in a coupled condition of two of the floor elements an intermediate distance is available between the decorative layers.

11 . A floor covering comprising a plurality of adjacent floor elements according to claim 1 .

12 . A floor covering comprising a plurality of adjacent floor elements, wherein at least one floor element of the plurality of floor elements comprises:

a decorative layer of ceramic;

a support layer arranged below the decorative layer, the support layer comprising a rigid polyvinylchloride (PVC), wherein the rigid PVC comprises less than 15 phr of plasticizer,

wherein the at least one floor element of the plurality of floor elements has an impact strength greater than 1.91 Newton-meter (Nm),

wherein the floor covering comprises the combination of the following features:

coupling elements configured to realize a coupling with coupling elements of adjacent floor elements; and

a grout filling an intermediate distance separating the decorative layers of the floor elements,

wherein the coupling elements comprise at least one male part and at least one female part,

wherein in a coupled condition of adjacent floor elements, locking surfaces are formed limiting the mutual movement of the adjacent floor elements in at least in a vertical direction,

wherein the male part protrudes outwardly beyond an upper edge of the decorative layer and the female part extends inwardly beyond an upper edge of the decorative layer to thereby form an undercut underneath the decorative layer so that the locking surfaces limiting the movement in the vertical direction are at least formed by a top surface of the male part and an upper surface of the undercut formed by the female part,

wherein the upper surface of the undercut is a bottom surface of the decorative layer delimiting the undercut in an upward direction,

wherein the floor element has an impact strength greater than 1.91 Newton-meter (Nm),

wherein in a coupled condition of the adjacent floor elements, the locking surfaces are formed, limiting the mutual movement of the adjacent floor elements in at least one horizontal direction,

wherein in a coupled condition of the adjacent floor elements, first locking surfaces are formed limiting the mutual movement of the adjacent floor elements in a horizontal direction along the coupled edges, as well as second locking surfaces limiting the mutual movement of the adjacent floor elements in a direction that is substantially horizontal and perpendicular to the coupled edges, and

wherein the locking surfaces comprise portions positioned on resilient arms.

13 . The floor covering according to claim 12 , wherein the floor covering comprises an underlayment beneath the plurality of floor elements configured to act as a moisture and/or noise barrier.

14 . The floor covering according to claim 12 , wherein the plurality of floor elements lie on a subsurface and wherein the plurality of floor elements are separated from the subsurface.

15 . The floor covering according to claim 12 , wherein the plurality of floor elements have an elongated shape.

16 . The floor covering according to claim 12 , wherein the plurality of floor elements are disposed in an offset relationship.
