Abstract:
1. A system for making a flooring which comprises rectangular floorboards which are mechanically lockable, in which system the individual floorboards along their long sides have pairs of opposing connectors for locking together similar floorboards both vertically and horizontally and along their short sides have pairs of opposing connectors which lock the floorboards horizontally, the connectors of the floorboards are adapted so as to allow locking-together of the long sides by angling along an upper joint edge and of the short sides by vertical folding, the system comprises two different types of floorboards, the connectors of one of the types of floorboards along one pair of opposite edge portions being arranged in a mirror-inverted manner relative to the corresponding connectors along the same pair of opposite edge portions of the other of the type of floorboards, a first short side being lockable to a long side vertically and horizontally, and a second short side being lockable to a long side horizontally by vertical folding, and horizontal connectors on the short sides having cooperating locking surfaces which are formed different from the cooperating locking surfaces of the horizontal connectors of the long sides wherein part of a horizontal connector comprises a separate locking strip of metal, the locking strip is mechanically fixed to the floorboard by means of a joint which is operable by snapping-in and/or at least inward angling, the locking strip is designed for connecting the floorboard with another floorboard of the system by at least inward angling, the floorboard comprising a laterally open strip groove in one joint edge portion and the locking strip comprising a strip tongue, the locking strip is mechanically fixed to the floorboard by way of said strip tongue being mechanically fixed within the strip groove only forming a joint which is operable by snapping in and/or inward angling, and the locking strip extends horizontally beyond the outer parts of the laterally open strip groove, and that the separate strip is a bent metal sheet.
