Abstract
Floor panels (1, 1′, 1″) are shown, which are provided with a mechanical locking system on long and short edges (5a, 5b, 4a, 4b) allowing installation with vertical folding and where the long edge (5a, 5b) locking system prevents separation of the short edges (4a, 4b) during the folding action.
Claims20
A short edge locking system for vertical and horizontal locking of adjacent edges of two similar floor panels for locking of the adjacent edges, wherein the two panels are connected by moving one of the two panels vertically relative to the other one of the two panels, wherein the locking system comprises a strip, a locking element and a locking groove for horizontal locking of the adjacent edges and a flexible tongue formed of a separate material and connected to an edge of the floor panels for vertical locking of the adjacent edges, wherein the flexible tongue comprises two flexible parts comprised of an inner flexible part configured to be located in an inner part of a displacement groove at an edge of one of the floor panels, and an outer flexible part configured to be located at an outer part of the displacement groove, wherein the outer flexible part extends vertically upwards or downwards,
- wherein the outer flexible part includes a rigid protrusion and a flexible knee joint.
A flexible tongue for vertical locking of floorboards, the flexible tongue comprising two flexible parts comprised of an inner flexible part configured to be located in an inner part of a displacement groove formed in an edge of one of the floorboards, and an outer flexible part configured to be located at an outer part of the displacement groove and to extend vertically upwards or downwards, wherein the outer flexible part includes a rigid protrusion and a flexible knee joint,
- wherein the flexible tongue between the outer flexible part and the inner flexible part includes an upper flange and a lower flange connected by a vertical web, and wherein the inner flexible part and the outer flexible part, in an unbent state of the inner flexible part and the outer flexible, intersect a common horizontal plane of the web portion.
A short edge locking system for vertical and horizontal locking of adjacent edges of two similar floor panels for locking of the adjacent edges, wherein the two panels are connected by moving one of the two panels vertically relative to the other one of the two panels, wherein the locking system comprises a strip, a locking element and a locking groove for horizontal locking of the adjacent edges and a flexible tongue formed of a separate material and connected to an edge of the floor panels for vertical locking of the adjacent edges,
- wherein the flexible tongue comprises two flexible parts comprised of an inner flexible part configured to be located in an inner part of a displacement groove at an edge of one of the floor panels, and an outer flexible part configured to be located at an outer part of the displacement groove,
- wherein the outer flexible part extends vertically upwards or downwards, and
- wherein the flexible tongue between the outer flexible part and the inner flexible part includes an upper contact surface and a lower contact surface which are substantially parallel.
