Abstract
Floor panels (1b, 1c) are shown which are provided with a mechanical locking system comprising a tongue with rocker arms that allows locking by a vertical turning motion.
Claims24
A set of floor panels 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, each of said floor panels comprising:
- a tongue on a first edge of a panel having a length direction extending parallel with the first edge;
- a tongue groove on a second opposite edge of the panel for receiving the tongue of an adjacent panel for mechanically locking together said adjacent edges in a vertical direction;
- wherein the tongue has an inner part mounted in a sideward open fixation groove in the first edge and an outer part extending beyond the vertical plane, the inner part is fixed in the sideward open fixation groove,
- wherein the tongue comprises at least one rocker arm extending in the length direction of the tongue, the rocker arm comprising a displaceable pressing protrusion that during locking is in contact with the second edge and a displaceable locking protrusion that in locked position cooperates with the tongue groove,
- wherein the locking protrusion 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.
A tongue comprising a main tongue body having an elongated shape and a length direction and adapted to be connected into a groove formed in a building panel wherein the tongue comprises at least one rocker arm located along its length and extending in the length direction of the tongue and wherein the rocker arm is displaceable such that one part of the rocker arm is displaceable inwardly towards the main tongue body and another part of the rocker arm is displaceable outwardly away from the main tongue body,
- wherein displacement of the one part of the rocker arm inwardly towards the main tongue body causes the another part of the rocker arm to be displaced outwardly away from the main tongue body.
A tongue comprising a main tongue body having an elongated shape and a length direction and adapted to be connected into a groove formed in a building panel wherein the tongue comprises at least one rocker arm located along its length and extending in the length direction of the tongue and wherein the rocker arm is displaceable such that one part of the rocker arm is displaceable inwardly towards the main tongue body and another part of the rocker arm is displaceable outwardly away from the main tongue body,
- wherein the another part of the rocker arm is displaced outwardly away from the main tongue body when the one part of the rocker arm is pressed and displaced inwardly towards the main tongue body;
- and
- wherein the rocker arm comprises protrusions protruding outwardly from the main tongue body and spaced from each other in the length direction of the tongue.
