Floor covering, floor element and method for manufacturing floor elements
View Patent ↗Floor covering, made of floor elements, which, at least at two opposite sides, comprise a male and a female coupling part, which allow that two of such floor elements can be interconnected at the respective sides at the respective sides by pushing one of these floor elements with the associated male coupling part, by means of a downward movement, home into the female coupling part of the other floor element, wherein at least one of said coupling parts, either the male coupling part or the female coupling part, is made as least partially in a filled synthetic material composite, such as extruded wood.
1. A floor element comprising:
a substrate; and
a top layer located above the substrate;
wherein the substrate comprises a filled synthetic material composite, including a synthetic material and a filling material;
wherein a mixing ratio between the synthetic material and the filling material is applied of between 70/30 and 20/80;
wherein the top layer is a wooden top layer or comprises a paper sheet immersed in synthetic material or resin;
wherein the floor element comprises coupling parts at a first pair of opposite sides;
wherein the coupling parts are performed as a male coupling part and a female coupling part;
wherein the coupling parts are provided with horizontally active locking portions, which, when two of such floor elements are coupled to each other, effect a locking in horizontal direction, perpendicular to respective sides of the first pair of opposite sides and in the plane of the coupled two of such floor elements;
wherein the coupling parts are provided with vertically active locking portions, which, when the two of such floor elements are coupled to each other, effect a locking in vertical direction, perpendicular to the plane of the coupled two of such floor elements;
wherein the coupling parts are arranged to couple the two of such floor elements at the respective sides by providing one of the two of such floor elements, with the associated male coupling part, by means of a turning movement, in the female coupling part of another one of two of such floor elements; and
wherein the substrate forms at least one side of the first pair of opposite sides, such that at least one of the coupling parts, either the male coupling part or the female coupling part, is made of the filled synthetic material composite.
2. The floor element of claim 1 , wherein the filled synthetic material composite comprises at least two zones of different composition.
3. The floor element of claim 2 , wherein the zones are obtained via co-extrusion.
4. The floor element of claim 1 , wherein the synthetic material comprises a thermoplastic material.
5. The floor element of claim 1 , wherein the synthetic material comprises a material chosen from a list containing polyethylene, polypropylene, polyurethane and polyvinylchloride.
6. The floor element of claim 5 , wherein the synthetic material comprises polyvinylchloride.
7. The floor element of claim 1 , wherein a ratio of the synthetic material and the filling material lower than 50:50 is applied.
8. The floor element of claim 1 , wherein the filling material comprises an inorganic filling material.
9. The floor element of claim 8 , wherein a ratio of the synthetic material and the filling material lower than 50:50 is applied.
10. The floor element of claim 1 , wherein the top layer is a wooden top layer.
11. The floor element of claim 1 , wherein the top layer comprises a paper sheet immersed in synthetic material or resin.
12. The floor element of claim 11 , wherein the top layer comprises a laminate layer of the DPL (Direct Pressure Laminate) or HPL (High Pressure Laminate) type.
13. The floor element of claim 1 , wherein the floor element comprises a backing layer located below the substrate.
14. The floor element of claim 1 , wherein the coupling part made of the filled synthetic material composite is entirely made of this filled synthetic material composite.
15. The floor element of claim 1 , wherein the substrate forms both sides of the first pair of opposite sides, such that the male coupling part and female coupling part are made of the filled synthetic material composite.
16. The floor element of claim 15 , wherein the male coupling part and the female coupling part are entirely made of the filled synthetic material composite.
17. The floor element of claim 1 , wherein the floor element comprises second coupling parts at a second pair of opposite sides;
wherein the second coupling parts are made as a male coupling part and a female coupling part;
wherein the second coupling parts are provided with horizontally active locking portions and vertically active locking portions; and
wherein the second coupling parts are arranged to couple the two of such floor elements at respective sides of the second pair of opposite sides by pushing the one of the two of such floor elements, with the associated male coupling part, by means of a downward movement, home into the female coupling part of the other one of the two of such floor elements.
18. The floor element of claim 17 , wherein a snap-on or engaging action takes place when coupling the two of such floor elements at the respective sides of the second pair of opposite sides.
19. The floor element of claim 18 , wherein said snap-on or engaging action is realized by means of a compressible portion present at the male or female coupling part; and
wherein the compressible portion is compressed during the snap-on or engaging action and relaxes at least partially at the end of the snap-on or engaging action.
20. The floor element of claim 19 , wherein the compressible portion is present at the female coupling part.
