Floor panel

1. A floor panel, comprising a core and a top layer of wood functioning as a visible decorative layer, the core comprising a first material and a different second material,

wherein the floor panel is rectangular and oblong and thus comprises a pair of opposite long sides and a pair of opposite short sides;

wherein the floor panel comprises, at the pair of opposite long sides, coupling parts, which, in a coupled condition, offer a horizontal as well as a vertical locking and which allow a mutual coupling by means of a pivoting movement between two floor panels to be coupled;

wherein the floor panel comprises, at the pair of opposite short sides, coupling parts;

wherein the coupling parts at the opposite short sides form a horizontally active locking system and a vertically active locking system;

wherein the horizontally active locking system comprises a male part and a female part, which allow that two of such floor panels can be connected to each other at the aforementioned short sides by providing one of these floor panels with the pertaining male part, by means of a downward movement obtained as a result of the aforementioned pivoting movement, in the female part of the other floor panel;

wherein the male part is formed by a downward-directed extremity of a hook-shaped part, whereas the female part comprises a seat formed by an upward-directed hook-shaped part;

wherein the vertically active locking system comprises a locking element provided in the form of an insert in one of the short sides;

wherein the core comprises, at least at one of the short sides, a strip made of the first material;

wherein at least the male or female part is machined from the first material of the strip;

wherein the insert extends a greater width at a locking portion compared to a support portion; and

wherein the locking portion extends generally vertically from the support portion, the support portion extending downwardly into and tangent to a seat defined by a surface of the hook-shaped part, the locking portion in the coupled condition contacting and extending tangent to the female part;

wherein the insert comprises a press-on portion extending inclinedly away from the locking portion and the support portion into the male part.

2. The floor panel of claim 1 , wherein the first material is MDF or HDF.

3. The floor panel of claim 1 , wherein at least the male or female part is milled in the first material of the strip.

4. The floor panel of claim 1 , wherein the core comprises at each short side a strip made of the first material; and wherein both the male and female part are machined from the first material of the respective strips.

5. The floor panel of claim 1 , wherein the second material is wood.

6. The floor panel of claim 1 , wherein the core is substantially composed of strips, comprising said strip made of the first material and strips made of the second material, which is wood.

7. The floor panel of claim 1 , wherein the floor panel comprises a backing layer of wood.

8. The floor panel of claim 1 , wherein the floor panel is of the engineered wood type.

9. The floor panel of claim 1 , wherein the insert is provided in a recess formed in the strip made of the first material.

10. The floor panel of claim 1 , wherein the insert is made of synthetic material.

11. The floor panel of claim 1 , wherein the insert comprises a pivotable lock-up body.

12. The floor panel of claim 1 , wherein the first material is located at an extremity of the floor panel, and the second material is located interiorly adjacent to the first material; and wherein the first material and the second material form discrete sections of the core.

13. The floor panel of claim 1 , wherein the support portion defines and/or extends below a junction between the press-on portion and the locking portion.

14. The floor panel of claim 1 , wherein the support portion defines a junction between the locking portion and a press-on portion that forms a v-shape.

15. The floor panel of claim 1 , wherein the insert is configured to define a gap between a lock-up body and the press-on portion of the insert.

16. The floor panel of claim 1 , wherein the support portion extends above a bottom surface of the hook-shaped part.
