Claims17
Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels at a vertical joint plane defined by adjoining uppermost surfaces of the first edge and the second edge, wherein said locking system comprises:
- a tongue and a tongue groove, for vertical locking, and
- at the first edge, a strip provided with a locking element, which cooperates for horizontal locking with a downwardly open locking groove formed in the second edge,
- wherein the strip comprises a strip body with a cavity, the cavity extending outside of the vertical joint plane relative to the first edge,
- wherein the second edge comprises a local protrusion that extends downwards, and
- wherein the protrusion is located in at least a portion of the cavity when the panels are locked vertically and horizontally, and the portion extends entirely through the strip body.
Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels, said locking system is configured to lock the edges by a vertical displacement of the first and the second edge relative each other, wherein the locking system comprises a tongue, which cooperates with a tongue groove or an undercut for vertical locking, and a strip, at the first edge, provided with a locking element, which cooperates for horizontal locking with a downwardly open locking groove formed in the second adjacent edge,
- wherein the strip comprises a strip body with a cavity,
- wherein the second edge comprises a local protrusion that extends downwards, and
- wherein the protrusion is located in at least a portion of the cavity when the panels are locked vertically and horizontally, and the portion extends entirely through the strip body.
Resilient floor panels with long and short edges provided with a locking system for vertical and/or horizontal locking of a first edge and a second edge of adjacent panels at a vertical joint plane defined by adjoining uppermost surfaces of the first edge and the second edge, the floor panels comprising a resilient material that allows a bending with overlapping short edges,
- wherein the first edge is a long edge provided with a plastic locking strip extending along the first edge and protruding horizontally from the edge,
- wherein the locking strip comprises at least one vertically extending protrusion configured to be inserted into a locking groove formed at the second edge, which is a long edge of an adjacent panel, and a cavity extending outside of the vertical joint plane relative to the first edge, and
- wherein the second edge comprises a local protrusion that extends downwards, and the protrusion is located in at least a portion of the cavity when the panels are locked together vertically and horizontally, and the portion extends entirely through the strip body.
Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels at a vertical joint plane defined by adjoining uppermost surfaces of the first edge and the second edge, wherein said locking system comprises:
- a tongue and a tongue groove, for vertical locking, and
- at the first edge, a strip provided with a locking element, which cooperates for horizontal locking with a downwardly open locking groove formed in the second edge,
- wherein the strip comprises a strip body with a cavity that penetrates through the strip body from a top surface of the strip body to an opposing bottom surface of the strip body, the cavity extending outside of the vertical joint plane relative to the first edge,
- wherein the second edge comprises a local protrusion that extends downwards,
- wherein the protrusion is located in the cavity when the panels are locked vertically and horizontally, and
- wherein the locking element is continuous along the first edge.
Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels, said locking system is configured to lock the edges by a vertical displacement of the first and the second edge relative each other, the locking system comprises a tongue, which cooperates with a tongue groove or an undercut for vertical locking, and a strip, at the first edge, provided with a locking element, which cooperates for horizontal locking with a downwardly open locking groove formed in the second adjacent edge,
- wherein the strip comprises a strip body with a cavity that penetrates through the strip body from a top surface of the strip body to an opposing bottom surface of the strip body,
- wherein the second edge comprises a local protrusion that extends downwards,
- wherein the protrusion is located in the cavity when the panels are locked vertically and horizontally,
- wherein the locking element is continuous along the first edge.
