Abstract
Floor panels are shown, which are provided with a mechanical locking system that may be locked with a vertical displacement of a first panel against a second panel. The locking system includes a flexible strip that during locking bends upwardly or downwardly. The locking system includes a first and a second joint edge section with different locking functions. One section provides a horizontal locking and another section provides a vertical locking.
Claims19
A set of floor panels, wherein a first edge and a second edge of each floor panel are provided with a mechanical locking system comprising a strip extending horizontally from a lower part of the first edge and a downwardly open locking groove formed in the second edge, the strip comprising an upwardly protruding locking element configured to cooperate with the locking groove for locking the first edge and the second edge,
- a first edge section and a second edge section being located along both the first edge and the second edge,
- wherein in a locked position:
- the first edge section is configured such that an outer groove wall of the locking groove and an inner surface of the locking element lock the first edge and the second edge in a horizontal direction parallel to a main plane of the floor panels,
- the second edge section is configured such that there is a space between the locking groove and the locking element, and
- an upper locking surface of the locking element and a lower locking surface of the locking groove are configured to lock the first edge and the second edge in a vertical direction perpendicularly to the horizontal direction,
- wherein the upper locking surface is provided in the second edge section and the first edge section is free of the upper locking surface, or wherein the lower locking surface is provided in the second edge section and the first edge section is free of the lower locking surface.
A set of floor panels, wherein a first edge and a second edge of each floor panel are provided with a mechanical locking system comprising a strip extending horizontally from a lower part of the first edge and a downwardly open locking groove formed in the second edge, the strip comprising an upwardly protruding locking element configured to cooperate with the locking groove for locking the first edge and the second edge,
- a first edge section and a second edge section being located along both the first edge and the second edge,
- wherein in a locked position:
- the first edge section is configured such that an outer groove wall of the locking groove and an inner surface of the locking element lock the first edge and the second edge in a horizontal direction parallel to a main plane of the floor panels,
- the second edge section is configured such that there is a space between the locking groove and the locking element, and
- an upper locking surface of the locking element and a lower locking surface of the locking groove are configured to lock the first edge and the second edge in a vertical direction perpendicularly to the horizontal direction,
- wherein the locking system is configured such that a vertical displacement of the second edge against the first edge during an initial stage of the vertical displacement bends the strip upwards towards a second panel of the set of floor panels such that the upper locking surface and lower locking surface overlap each other.
A set of floor panels, wherein a first edge and a second edge of each floor panel are provided with a mechanical locking system comprising a strip extending horizontally from a lower part of the first edge and a downwardly open locking groove formed in the second edge, the strip comprising an upwardly protruding locking element configured to cooperate with the locking groove for locking the first edge and the second edge,
- a first edge section and a second edge section being located along both the first edge and the second edge,
- wherein in a locked position:
- the first edge section is configured such that an outer groove wall of the locking groove and an inner surface of the locking element lock the first edge and the second edge in a horizontal direction parallel to a main plane of the floor panels,
- the second edge section is configured such that there is a space between the locking groove and the locking element, wherein the space is bounded by the inner surface of the locking element in the second edge section along a horizontal plane, and
- an upper locking surface of the locking element and a lower locking surface of the locking groove are configured to lock the first edge and the second edge in a vertical direction perpendicularly to the horizontal direction.
