Abstract
Floor panels are shown, which are provided with a vertical locking system on short edges comprising a displaceable tongue that is displaced in one direction into a tongue groove during vertical displacement of two panels. The displaceable tongue may be provided in a sidewardly open displacement groove at an edge of a building panel, the displaceable tongue including a main body extending along the edge of the panel and a tongue locking surface located at an upper and outer part of the tongue.
Claims21
Building panels comprising a first building panel and a second building panel, the building panels comprising:
- a horizontal locking system comprising a locking element provided in the first building panel and a locking groove provided in the second building panel;
- and
- a vertical locking system comprising a tongue groove provided in the first building panel and a displacement groove provided in the second building panel,
- wherein a displaceable tongue is provided in the displacement groove,
- wherein the displaceable tongue has a first portion and a second portion along a longitudinal direction of the displaceable tongue, the longitudinal direction being perpendicular to a transversal direction of the displaceable tongue, a width of the first portion along the transversal direction being larger than a width of the second portion along the transversal direction,
- wherein the first portion contacts said locking element during locking of the building panels for displacing the displaceable tongue into said tongue groove,
- wherein juxtaposed upper parts of respective first and second edges of the first and second building panels in a locked position define a vertical plane having opposite first and second sides, the upper part of the first edge of the first building panel being located on the first side of the vertical plane, and the entire locking element of the first building panel being located on the second side of the vertical plane,
- wherein an upper surface of an innermost portion of the displaceable tongue is free from contact with the second building panel.
Building panels comprising a first building panel and a second building panel, the building panels comprising:
- a horizontal locking system comprising a locking element provided in the first building panel and a locking groove provided in the second building panel;
- and
- a vertical locking system comprising a tongue groove provided in the first building panel and a displacement groove provided in the second building panel,
- wherein a displaceable tongue is provided in the displacement groove,
- wherein the displaceable tongue has a first portion and a second portion along a longitudinal direction of the displaceable tongue, the longitudinal direction being perpendicular to a transversal direction of the displaceable tongue, a width of the first portion along the transversal direction being larger than a width of the second portion along the transversal direction,
- wherein the first portion contacts said locking element during locking of the building panels for displacing the displaceable tongue into said tongue groove,
- wherein the locking element comprises an inner surface facing an inner or a center part of the first building panel,
- wherein the first portion engages at least a portion of the inner surface during locking, said inner surface being inclined with respect to a horizontal plane which is parallel with a surface layer of the first building panel,
- wherein the locking element is provided adjacent to a strip protruding outwardly beyond an uppermost part of an edge of the first building panel, and
- wherein said inclined inner surface extends from an upper portion of the locking element to said upper part of the strip.
