Mechanical locking of floor panels
Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.
1. A set of floor panels provided with a locking system comprising a separate part in a first edge of a first floor panel and a groove in a second edge of a similar second floor panel,
wherein the separate part is configured to cooperate with the groove to lock the first edge of the first floor panel and the second edge of the second floor panel into a locked state in which the first and second edges are locked horizontally adjacent to one another, the first and second edges extending in a longitudinal direction,
wherein the separate part is positioned in a displacement groove and is configured to turn during locking,
wherein the separate part comprises a turning extension which, in the locked state, is positioned outside the displacement groove and extends beyond a longitudinal end of the first edge when viewed in a direction orthogonal to a horizontal plane, and
wherein the turning extension is configured to turn the separate part during locking when the first floor panel and the second floor panel are positioned in a same plane to obtain the locked state.
2. The set of floor panels as claimed in claim 1 , wherein the turning extension is at an outer edge of the separate part.
3. The set of floor panels as claimed in claim 2 , wherein the first edge of the first floor panel is a short edge and the turning extension is positioned at an adjacent long edge of the first floor panel.
4. The set of floor panels as claimed in claim 3 , wherein the first edge of the first floor panel comprises a locking strip with an upwardly directed locking element which is configured to cooperate with a downwardly open locking groove at the second edge of the second floor panel for locking the first edge of the first floor panel and the second edge of the second floor panel in a horizontal direction.
5. The set of floor panels as claimed in claim 4 , wherein the turning extension, in the locked state, is positioned outside the locking strip and extends beyond a longitudinal end of the locking strip when viewed in the direction orthogonal to the horizontal plane.
