Floor panel assembly

1. A floor panel assembly comprising:

sheet-shaped floor panels having edges, a lower side and an upper side, each floor panel being provided on at least a first edge with a first joining member and, on a second edge, with a second joining member, the first and second joining members of two adjacent panels configured to be joined by a movement of the two adjacent panels with their first and second edges towards each other such that in a joined position the two adjacent panels meet each other near their upper side along a scam, the first and second joining members locking the two adjacent panels at adjacent first and second edges at least in a direction perpendicular to the upper side and in a direction parallel to the upper side but perpendicular to the adjacent first and second edges in their joined position; and

at least one locking element which is provided on one of the first and second joining members and comprises a first locking surface co-operating with a second locking surface on the other of said first and second joining members, wherein the locking surface of the locking element is movable from a first position allowing the first and second joining members to be joined, to a second position in which the locking surface locks the first and second joining members to each other, said locking clement having a locking portion on one end bearing said first locking surface and a control portion near a second end as well as a connecting portion between the locking portion and the control portion, said connecting portion being slidably accommodated in a channel and is pushed towards a first end of the channel when the locking surface is moved from the first to the second position by a movement of the control portion extending from an opposite end of the channel for co- operation with the other of said first and second joining members wherein the first and second joining members arc configured as a male and female joining member, the locking element being connected to the male joining member.

2. The floor panel assembly of claim 1 , wherein the control portion of the locking clement has a control surface, such that the control surface of the control portion co-operates with a control surface of the other of said first and second joining members, at least one of the control surfaces being inclined with respect to a direction of movement of the locking portion and with respect to a direction of movement of the panel edges to move the locking portion and the locking surface of the locking clement from the first to the second position.

3. The floor panel assembly of claim 1 , wherein the male joining member is provided with a protrusion extending away from the upper side of the panel, the channel extending through said protrusion.

4. The floor panel assembly of claim 1 , wherein the female joining member comprises a control portion for cooperation with the control portion of the locking clement to move the locking clement when the panel edges move towards each other.

5. The floor panel assembly of claim 4 , wherein the female joining member comprises a lip protruding substantially parallel to and from the lower side of the panel at the first edge, said lip having a depression to accommodate the protrusion of the male joining member, said depression having an upright projection near a free end of the lip forming the control portion of the female joining member.

6. The floor panel assembly of claim 1 wherein the locking portion of the locking clement extends at least along a part of a length of the respective panel edge and is accommodated in a groove extending along the length of the panel edge, the locking clement having a plurality of connecting portions connected to the locking portion, each connecting portion disposed in a channel, the locking clement further having a control portion connected to each connecting portion opposite the locking portion.

7. The floor panel assembly of claim 1 , wherein the connecting portion of the locking element includes a spring to absorb the movement of the control portion and to cause movement of the locking portion when the first and second locking surfaces arc allowed to engage.

8. The floor panel assembly of claim 1 , wherein the first and second locking surfaces arc inclined with respect to the upper surfaces of the adjacent panels when connected.

9. The floor panel assembly of claim 1 , wherein the male joining member is provided with a protrusion extending away from the upper side of the panel, the channel extending through said protrusion and substantially parallel to the upper side of the respective panel.

10. The floor panel assembly of claim 2 , wherein the control surface of at least the control portion is inclined with respect to a direction of movement of the locking portion.

11. The floor panel assembly of claim 10 , wherein the control surface of the other of said first and second joining members is inclined with respect to a direction of movement of the locking portion.

12. The floor panel assembly of claim 1 , wherein the locking portion of the locking element is a tongue slidingly accommodated in a groove extending parallel to the respective edge, the channel having a height greater than that of the groove.

13. The floor panel assembly of claim 12 , wherein the channel is a slit opening to the lower side of the panel.

14. The floor panel assembly of claim 1 , wherein the other of said first and second joining members comprises a control portion for cooperation with the control portion of the locking element to move the locking element when the panel edges move towards each other.

15. A floor panel configured to be fixed to a second floor panel along edges thereof, the floor panel comprising:

a lower side;

an upper side;

first joining member on a first edge that joins the lower side to the upper side;

a second joining member on a second edge opposite the first edge wherein the second edge connects the lower side and upper side, the first and second joining members being complimentary configured such that when two adjacent panels are joined by a movement of the two adjacent panels with their first and second edges towards each other the two adjacent panels meet each other near their upper side along a seam in a joined position, the first and second joining members being configured so as to lock the two adjacent panels at adjacent first and second edges at least in a direction perpendicular to the upper side and in a direction parallel to the upper side but perpendicular to the adjacent first and second edges in the joined position, wherein the first joining member includes a channel extending from the first edge to a recess opening to a lower surface of the panel, the recess having an upper recess surface facing in a direction of the lower side and an end recess surface facing in a direction of the first edge; and wherein the second joining member includes a projection configured to extend into the recess when the adjacent panels are in the joined position.
