MECHANICAL LOCKING SYSTEM FOR FLOOR PANELS

摘要

Floor panels are shown, which are provided with a mechanical locking system comprising a tongue with rocker arms that allows locking by a vertical turning motion. The tongue has an inner part mounted in a sideward open fixation groove in a first edge and an outer part extending beyond a vertical plane, the inner part is fixed in the sideward open groove, wherein the tongue has at least one rocker arm extending in the length direction of the tongue, the rocker arm having a displaceable pressing protrusion that during locking is in contact with a second edge and a displaceable locking protrusion that in locked position cooperates with a tongue groove, wherein the locking protrusions are displaced outwardly away from the main tongue body when the pressing protrusion is pressed and displaced inwardly towards the inner part of the tongue.

主权项

1. A set of floor panels (1b, 1c) which are mechanically connectable to each other along one pair of adjacent edges by a vertical motion, so that upper joint edges of said floor panels in the connected state define a vertical plane (VP), each of said floor panels comprising:
a tongue (30) on a first edge of a panel (1b) having a length direction (L) extending parallel with the first edge; a tongue groove (31) on a second opposite edge (1c) of the panel for receiving the tongue of an adjacent panel for mechanically locking together said adjacent edges in a vertical direction; characterized in that the tongue has an inner part (IP) mounted in a sideward open fixation groove (32) in the first edge and an outer part (OP) extending beyond the vertical plane VP, the inner part (IP) is fixed in the sideward open groove (32), wherein the tongue comprises at least one rocker arm (20) extending in the length direction L of the tongue, the rocker arm comprising a displaceable pressing protrusion (22) that during locking is in contact with the second edge and a displaceable locking protrusion (23) that in locked position cooperates with the tongue groove (31), wherein the locking protrusions is displaced outwardly away from the main tongue body when the pressing protrusion is pressed and displaced inwardly towards the inner part of the tongue.
