Abstract
Floor panels are shown, which are provided with a vertical folding locking system on short edges that only locks vertically and a mechanical locking system on long edges that prevents displacement along the long edges. A locking system for primarily rectangular floor panels with long and short edges installed in parallel rows, which allows that the short edges may be locked to each other with a vertical movement without a horizontal connection and that such horizontal connection is accomplished by the locking system on the long edges including a first and second horizontal locking perpendicular to the edges and along the edges.
Claims16
Floor panels provided with a locking system comprising a tongue and a tongue groove for mechanically locking together adjacent first and second edges vertically to a horizontal plane, thereby forming a vertical mechanical connection between the floor panels, the second edge being opposite to the first edge, the locking system further comprising a locking element at the first edge and a locking groove at the second edge forming a first horizontal mechanical connection between the adjacent first and second edges for locking the floor panels to each other in a direction parallel to the horizontal plane and at right angles to said first and second edges,
- wherein the first and second edges are provided with a second horizontal mechanical connection configured to lock the floor panels to each other along said first and second edges, in a direction parallel to the horizontal plane and parallel to said first and second edges, while the floor panels are locked in the direction parallel to the horizontal plane and at right angles to said first and second edges, and
- wherein the locking element and the locking groove comprise two sets of cooperating locking surfaces,
- a first set of the two sets of cooperating locking surfaces being located closer to a vertical plane and upper joint edges than a second set of the two sets of cooperating locking surfaces, and
- wherein said second horizontal mechanical connection comprises friction cavities located at the locking element, the friction cavities extending to an uppermost surface of the locking element.
