Panel

1. A panel, which, at least at two opposite sides, comprises coupling parts, with which two of such panels can be brought in a coupled condition;

wherein these coupling parts 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 panels can be connected to each other at said sides by providing one of these panels with the pertaining male part, by means of a downward movement, in the female part of the other panel;

wherein the vertically active locking system comprises a locking element, which, in the form of an insert, is provided in the side having the male part;

wherein this locking element comprises at least a pivotable lock-up body, said lock-up body being directed upward;

wherein the lock-up body, at one extremity, forms a stop-forming locking portion, which can cooperate with a locking portion of a similar coupled panel, the locking element comprising a strip which is attached in a recess in the panel by means of an attachment portion which retains the strip in the recess, wherein said pivotable lock-up body in the non-coupled condition extends horizontally at least for a part underneath the attachment portion, however, wherein a vertical mutual distance is maintained between the lock-up body and the attachment portion;

wherein the locking element comprises an elastic bending zone, which forms a connection between the attachment portion and the pivotable lock-up body;

wherein the bending zone is a hinge portion; and

wherein the bending zone and the lock-up body are formed from synthetic material with different material characteristics such that a material of the bending zone is more flexible than a material of the lock-up body.

2. The panel of claim 1 , wherein the smallest vertical distance between the respective portions of the lock-up body and the attachment portion is smaller than 0.4 millimeters.

3. The panel of claim 1 , wherein the locking element consists of a coextruded synthetic material strip with, seen in cross-section, a plurality of zones of synthetic material with different characteristics including at least a first zone formed by said lock-up body and at least a second zone formed by said elastic bending zone.

4. The panel of claim 1 , wherein said pivotable lock-up body, in the non-coupled condition, adopts an orientation which forms an angle of less than 60° with the panel surface.

5. The panel of claim 1 , wherein said lock-up body, in the coupled condition of two of such panels, extends over a vertical distance which is smaller than 1.4 times the vertical distance defined by said attachment portion.

6. The panel of claim 1 , wherein said pivotable lock-up body, in the coupled condition, extends horizontally at least for a part underneath the attachment portion.

7. The panel of claim 1 , wherein the lock-up body defines a surface which, when performing said downward movement, comes into contact with an upper edge of the other panel, wherein the surface, when said contact occurs, shows a tangent line forming an angle (A3) of 45° or less with an upper surface of the panels.

8. The panel of claim 1 , wherein the lock-up body has a surface which, when performing said downward movement, comes into contact with an upper edge of the other panel, wherein the surface, when contact is effected, shows a tangent line forming an angle (A3) of 20 to 45° with an upper surface of the panels.
