Patent ID: 7841150

Claim:
A floorboard comprising: an upper side and a lower side opposite the upper side, the lower side configured to face a subfloor; connecting means integrated with the floorboard and adapted to connect a first edge of the floorboard with a second edge of an essentially identical floorboard, wherein upper joint edges of said floorboard and said essentially identical floorboard in a connected state define a vertical plane, said connecting means being adapted to connect said floorboard with said essentially identical floorboard in at least a horizontal direction perpendicular to said vertical plane, said connecting means comprising a locking strip which projects from said vertical plane and carries a locking element which is adapted to cooperate, in said connected state, with a downward open locking groove of said essentially identical floorboard, said locking strip is a separate part which is mechanically fixed to the floorboard in said horizontal direction and a vertical direction, wherein said locking strip is mechanically fixed to the floorboard at a joint by snapping-in or inward angling, said locking strip comprising a strip tongue, said locking strip adapted for connecting the floorboard with the essentially identical floorboard by at least inward angling, such that when the second edge is pressed against an upper part of the first edge and is then angled down, the locking element can enter the locking groove, wherein the joint comprises a strip groove adapted to receive the strip tongue and wherein the strip groove is a sideward open groove having an upper surface and a lower surface opposite the upper surface, the strip groove adapted for retaining the strip tongue in the strip groove when the strip groove is arranged in connection to the strip tongue, the locking strip is mechanically fixed to the floorboard by way of said strip tongue being mechanically fixed within the strip groove forming a joint which is only operable by snapping in and/or inward angling and wherein the locking strip extends horizontally beyond the outer parts of the strip groove.
