METHOD FOR PLACING AND MECHANISMALLY ASSEMBLING CHAO PAINTS AND A METHOD FOR PRODUCING A CHAO

摘要

A locking system for a pair of floor panels (1, 2), said floor panels (1, 2) for mechanically and releasably locking together adjacent short edges of pairs of adjacent panels (1, 2) when said adjacent panels are in a state of assembly where they are laying flat on a subfloor (12) with upper corner portions of said adjacent short edges being mutually spaced apart is disclosed. The mechanical locking system comprises a first mechanical connection (24, 30), formed by said adjacent short edges, for locking said adjacent short edges to each other in a vertical direction (D1), and a second mechanical connection (6, 8, 14) for locking said adjacent short edges to each other in a horizontal direction (D2) at right angles to said short edges. The second mechanical connection includes: (i) a locking groove (14) formed in the underside of the panel and extending parallel to and spaced from a short edge of one panel of said adjacent panels (1, 2) and being open at the rear side of said one panel (2), and (ii) a flexible and resilient locking strip (6) integrated with the other panel (1) of said adjacent panels (1, 2), said strip (6) extending throughout substantially the entire length of the corresponding short edge and being provided with a locking element (8) projecting from the locking strip (6).
