MECHANICAL LOCKING SYSTEM FOR FLOOR PANELS

摘要

Floor panels are shown, which are provided with a vertical locking system on short edges including a displaceable tongue that is displaced in one direction into a tongue groove during vertical displacement of two panels. Building panels provided with a locking system for vertical locking of a first and a second building panel by a vertical displacement of the panels relative each other, a displaceable tongue is in a sidewardly open displacement groove provided at an edge of a first panel, said tongue cooperates with a tongue groove provided at an adjacent edge of a second panel for locking the edge and the adjacent edge vertically.

1. Building panels provided with a locking system for vertical locking of a first and a second building panel by a vertical displacement of the panels relative each other, a displaceable tongue is in a sidewardly open displacement groove provided at an edge of a first panel, said tongue cooperates with a tongue groove provided at an adjacent edge of a second panel for locking the edge and the adjacent edge vertically, a strip protrudes:
below the displacement groove and outwardly beyond the upper part of the edge; or below the tongue groove and outwardly beyond the upper part of the adjacent edge, wherein the displaceable tongue comprises a pulling extension at its outer part configured to cooperate with a pulling protrusion formed at the adjacent edge such that the displaceable tongue is pulled out from the displacement groove and into the tongue groove when the edges of the panels are displaced vertically against each other.
