Système de plancher comprenant des planches de plancher connectables mécaniquement

摘要

A flooring system comprises a plurality of floor panels (1,1'') which are mechanically connectable to each other along one pair of adjacent edges, said floor panels comprising a tongue (10) and a groove (9), formed in one piece with the panels for mechanically locking together said one pair of adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connections (D1) between the panels and a first locking element (8) at one first edge formed in one piece with the panel and a second locking element (15), formed of a separate material connected to the panel, said first and second locking elements form a mechanical connection locking the panels to each other horizontally parallel to the principal plane and at right angles to the joint edges (D2) whereby said floor panels (1,1') can be mechanically joined by displacement of said two panels horizontally towards each other, while the first locking element (8) and the second locking element (15) are displaced first vertically away from each other and than vertically towards each other. The second locking element (15) is made of a sheet shaped material which has a higher density than the material of the first locking element. The second locking element has a first (40) and a second (41) surface and an edge portion (42) between the first (40) and second (41) surfaces, whereby the edge portion (42) forms at least a part of a second locking surface (22) which is in contact with a first locking surface (20) of the first locking element and prevents horizontal separation of the panels.
