Abstract
The invention relates to a locking system for mechanical joining of floorboards () which have a body (), a lower balancing layer () and an upper surface layer (). A strip () is integrally formed with the body () of the floorboard () and extends under an adjoining floorboard (). The strip () has a locking element (), which engages a looking groove () in the underside of the adjoining floorboard () and forms a horizontal joint. A tongue () and a tongue groove () form a vertical joint between upper and lower plane-parallel contact surfaces () and are designed in such manner that the lower contact surfaces () are on a level between the upper side of the locking element () and a plane containing the underside () of the floorboard. The invention also relates to a floorboard having such a locking system, a floor made of such floorboards, as well as a method for making such a locking system.
