Claim:
A floor panel comprising, at least at two opposite sides, coupling parts with which two of such floor panels can be coupled to each other; wherein the 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 enable connection between first and second floor panels at said sides by providing one of the floor panels with the respective male part, by means of a downward movement, in the female part of the other floor panel; wherein the vertically active locking system comprises a locking element, which is provided in the form of an insert in one of the sides concerned; wherein the locking element comprises at least a pivotable lock-up body; wherein the lock-up body at a first extremity has an outer peripheral surface forming a stop-forming locking portion arranged to abut a locking surface of the first floor panel when the first and second floor panels are coupled; wherein the pivotable lock-up body has a second extremity opposite from said first extremity forming an outer peripheral surface including a support portion arranged to abut and rotate against a support surface of the second floor panel as the stop-forming locking portion of the lock-up body is brought into engagement with the locking surface of the first panel; wherein said support portion mainly defines a local pivot zone, said pivotable lock-up body being angularly movable with respect to said pivot zone, the support portion is rotatable about a support point defined along a vertical line as the first and second panels are brought into a coupled condition, the locking portion defines a contact point arranged for abutment against the first floor panel, and the contact point is displaced from at least a first position to at least a second position as the first and second panels are brought into engagement, wherein the second position is closer to the vertical line than the first position.
