Mechanical locking of floor panels
Floor panels ( 1, 1 ′) are shown, which are provided with a mechanical locking system on long ( 5 a, 5 b ) and short edges ( 4 a, 4 b ) allowing installation with angling of long edges and where the short edge locking system has a displaceable tongue that is displaceable essentially in one direction from an inner unlocked position to an final locked position.
1. Method of locking a set of floor panels provided with a locking system comprising a separate flexible tongue arranged in a displacement groove at an edge of one floor panel, and a tongue groove at an adjacent edge of a similar floor panel, wherein the method comprises the step of inserting a needle shaped tool into the displacement groove and displacing the flexible tongue into the tongue groove to obtain a vertical locking of the edge of the one floor panel and the adjacent edge of the similar floor panel.
2. The method as claimed in claim 1 , wherein the locking system comprises a friction connection.
3. The method as claimed in claim 1 , wherein the one floor panel and the similar floor panel are installed in last row adjacent to a wall.
4. The method as claimed in claim 1 , wherein the one floor panel and the similar floor panel are installed in a first row adjacent to a wall.
5. The method as claimed in claim 1 , wherein the flexible tongue is bendable.
6. The method as claimed in claim 2 , wherein the friction connection is on the flexible tongue.
7. The method as claimed in claim 1 , wherein the displacing of the flexible tongue is by a bending principle.
8. The method as claimed in claim 1 , wherein the displacing of the flexible tongue is by a link principle in which a portion of the flexible tongue is rotated around a point.
9. The method as claimed in claim 1 , wherein the displacing of the flexible tongue is by a wedge principle.
10. The method as claimed in claim 1 , wherein the one floor panel and the similar floor panel are configured to be locked with angling or a vertical motion.
11. The method as claimed in claim 1 , wherein the displacing of the flexible tongue causes at least a part of the flexible tongue to be bent in a length direction of the flexible tongue.
