Abstract
Floor panels are shown, which are provided with a mechanical locking system having 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.
Claims32
A set of floor panels provided with a locking system comprising a displaceable tongue in a displacement groove at a first edge of a first floor panel and a tongue groove in an adjacent first edge of a similar second floor panel for connecting the edges vertically, the first floor panel including a second edge orthogonal to the first edge, the second edge having a vertical joint plane on an upper part of the second edge for abutting against an edge of a third floor panel, wherein the tongue and the tongue groove are displaceable in relation to each other and the tongue is displaced in a direction essentially along and parallel with the adjacent first edges during locking of the floor panels, the tongue comprises a pressing part that protrudes from the vertical joint plane on the upper part of the second edge and a protrusion extending horizontally beyond the upper part of the first edge, and wherein the tongue groove comprises a protrusion and a cavity configured such that the adjacent first edges can obtain a vertically unlocked position where the protrusion of the tongue matches the cavity of the tongue groove and a vertically locked position where the protrusion of said tongue vertically overlaps the protrusion of said tongue groove.
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 an adjacent first edge of a similar second floor panel for connecting the first edges vertically and/or horizontally, the first floor panel including a second edge orthogonal to the first edge, the second edge having a vertical joint plane on an upper part of the second edge for abutting against an edge of a third floor panel, wherein the separate part comprises a pressing part that protrudes from the vertical joint plane on the upper part of the second edge, and the separate part is displaceable in a direction along and parallel with the adjacent edges during locking of the floor panels and the adjacent edges are configured to be locked vertically and/or horizontally by only a displacement of the separate part along and parallel with the adjacent edges.
A set of floor panels provided with a locking system comprising:
- a tongue at an edge of a first floor panel and a tongue groove in an adjacent edge of a similar second floor panel for connecting the edges vertically;
- a locking strip with an upwardly directed locking element at the edge of the first floor panel and a downwardly open locking groove at the adjacent edge of the similar second floor panel for connecting the adjacent edges in a horizontal direction perpendicular to the adjacent edges, the locking strip being vertically lower than the tongue on the edge of the first panel and extending continuously along the edge of the first floor panel;
- wherein the tongue and the tongue groove are displaceable in relation to each other, and the tongue comprises a protrusion extending horizontally beyond the upper part of the edge and the tongue groove comprises a protrusion and a cavity configured such that the adjacent edges can obtain a vertically unlocked position where the protrusion of the tongue matches the cavity of the tongue groove and a vertically locked position where the protrusion of said tongue vertically overlaps the protrusion of said tongue groove.
