Abstract
A device for locking two building boards connected to one another in a direction (V) perpendicular to a visible side. The device includes a first building board with a lateral edge (I) and a first groove and running parallel to the visible side. The device further includes at least one second building board with a lateral edge (II) and with a second groove and running parallel to the visible side, and a locking element that is placed in the first groove of the first building board to engage in the second groove of the second building board, when both grooves have reached an overlapping position after the connection of the building boards by a vertical lowering movement.
Claims14
A device for locking two building boards connected to one another in a direction (V) perpendicular to a visible side, comprising:
- a first building board with a lateral edge (I) and a first groove provided in a core of the building board and running parallel to the visible side;
- at least one second building board with a lateral edge (II) and with a second groove provided in the core of the building board and running parallel to the visible side;
- and
- a locking element that is placed in the first groove of the first building board in order to engage in the second groove of the second building board, when the first groove and the second groove have reached an overlapping position after connection of the building boards by a vertical lowering movement,
- to lock the two building boards in a direction (H) parallel to the visible side, on one of the lateral edges (I), a lower lip projecting laterally beyond the lateral edges with an outer projection projecting upwards is provided and on the lateral edge (II) lying opposite the lateral edge (I), a depression is provided directed towards an underside, the depression is embodied in a manner corresponding to the projection,
- the locking element is configured to be bent out in a transverse direction (H) by forces acting thereon in a longitudinal direction (L), and the locking element has at least one projection facing a groove base, a portion of the projection at least partially extends and is fixed in a depression provided in said groove base of the first groove and projecting into the core and locked in place based on the longitudinal direction (L).
