Patent attributes
Floor laying system for joining together floorboards, including grooves made in opposing side edges of the boards, and a separate profiled rail, which is disposed between the side edges of the boards and couples together the boards and which has legs projecting to opposite sides from a central section of the rail, which legs are designed to lockingly engage in the grooves in the respective opposing side edges of the floorboards. The legs of the profiled rail delimit a channel-shaped cavity which can accommodate at least one line element. The profiled rail has legs, which supportively bear against diagonally opposing beveled faces of the grooves in two adjacent boards, in addition to which a slot running substantially parallel with the top and bottom sides of the respective board opens into the groove to form a resilient tongue.
