Abstract
Floor panels provided with a mechanical locking system comprising a separate material in order to reduce snapping resistance during vertical displacement. For example, a separate flexible tongue, the flexible tongue including an inner part, which is connected to a holding groove at a second edge, and an outer flexible snap tab that extends upwardly and in the connected state into a cavity under a protruding tongue for locking a first and a second floor panel to each other in a vertical direction.
Claims18
A set of floor panels which are mechanically connectable to each other at a first edge and a second edge of a first floor panel and a second floor panel, respectively, wherein an upper end of said first edge and an upper end of said second edge in a connected state of the floor panels define a vertical plane, wherein
- the first edge is provided with a protruding tongue formed in one piece with a core of the first floor panel, said protruding tongue extends beyond the vertical plane,
- the second edge is provided with a separate flexible tongue,
- the flexible tongue comprises an inner part, which is connected to a holding groove at the second edge, and an outer flexible snap tab that extends upwardly in the connected state into a cavity under the protruding tongue for locking the first floor panel and the second floor panel to each other in a vertical direction,
- the first edge comprises a strip with a locking element that is provided farther beyond the vertical plane than the protruding tongue,
- the second edge comprises a locking groove, which is open towards a rear side of the second floor panel that faces a subfloor,
- a locking surface of the locking element is configured to cooperate, in the connected state, with a locking surface of the locking groove for locking the first floor panel and the second floor panel to each other in a horizontal direction, which is at a right angle to the first edge and the second edge,
- wherein the first floor panel and the second floor panel are mechanically connectable by a vertical displacement towards each other, wherein the flexible snap tab and the protruding tongue are configured to cooperate during said displacement such that at least a part of the flexible snap tab is, when the first floor panel and the second floor panel are vertically displaced towards each other, in a position, resiliently displaced towards the second edge by the protruding tongue, and that the flexible snap tab is, when the first floor panel and the second floor panel are in the connected state, displaced towards the first edge.
