Definitions

  • the present invention relates to a joining system for floorboards, panels and sheaves, but foremost for parquetry.
  • the invention will replace the traditional groove and tenon technique.
  • the boards can be joined in a substantially vertical movement and then be locked by a horizontal movement in the longitudinal direction of the boards.
  • the protrusion is shaped like hooks engaging the groove. Through this, the joining will be very simple to perform, whilst at the same time providing a strong joint.
  • the present inventor has realised that the joining will be simpler if the necessary angle between the boards is reduced and the boards can be joined with an almost vertical movement. This is achieved by providing milled slots in the protrusions and in the lower edge of the recesses, allowing the board to be joined to be inserted into the already laid-down board more or less from above. The new board can then be displaced longitudinally to obtain the final locking thereof.
  • the invention allows for simple floor-laying that can easily be performed by one person. At the same time, the board manufacturing process is not made notably more complicated.
  • the invention thus relates to a joining system for floorboards, comprising boards intended to be joined together.
  • the first board has a protrusion fitting into a recess in the second board.
  • the protrusion on the first board exhibits hooks with intermediate slots
  • the recess of the second board is delimited in the upwards direction by a solid edge, and in the downwards direction by an edge with heads, sized so as to enable insertion through the slots in the first board.
  • the lower edge of the recess has shoulders between the heads.
  • the invention also relates to a corresponding board for such a joining system.
  • the invention will be illustrated by means of an embodiment where the floorboards are made of wood. It should be understood that other materials, such as laminates, plastic, etc. could be used just as well.
  • Figs 1 and 2 two boards A and B are shown in a cross sectional view from their short sides.
  • the boards have an upper wear layer 8 of hardwood and a carrier layer of simpler wood, as is conventional. It should be understood that the boards A and B are identical, but Figs 1 and 2 show only the joint between a right hand long side of board A and a left hand long side of board B.
  • board A exhibits hooks 1 with intermediate milled slots or cuts 2.
  • Board B has a recess 11, corresponding to a traditional groove. The recess is delimited on the top side by a solid edge 3, and on the bottom side by a non-solid edge comprising heads 4 with intermediate milled slots. Preferably, these slots do not extend to the full depth of the recess 11 but there is a shoulder 7 remaining. The function of the shoulder 7 will be described below.
  • the joining is performed as follows:
  • Board A is laid in place and is to be joined with the next board B.
  • Board B is fitted from above in such a way that the heads 4 will pass through the slots 2 of board A. Through angling board B somewhat, and holding it at an appropriate distance from board A, the shoulders 7 will be allowed to pass the hooks.
  • board B can be displaced longitudinally, into its correct position in relation to the walls and the other floorboards.
  • the heads 4 will thereby also be displaced to a location below the hooks 1, to form a strong joint.
  • the joint may be further reinforced by glue, applied e.g. to the top side 5 of the hooks before mounting board B.
  • the shoulders 7 may for example be about 2 mm long. It is also conceivable to mill away the shoulders 7 completely, down to the bottom of the recess.
  • Board B can then be laid down entirely vertically, but at the same time, the joint will be weakened, as the entire head 4 generally will not happen to be located below a hook 1.
  • the top side 5 of the hook 1 is preferably angled, as is the matching underside 6 of the recess 11.
  • a suitable angle is about 45°.
  • the hooks may also have other profiled shapes than the configuration shown with straight edges and a flat exterior end surface, e.g. convexely or concavely rounded shapes or other curved and hook-shaped configurations (not shown).
  • the recess will have a complementary shape. The main point is that the configuration should result in that the boards A and B cannot be pulled away from each other sideways after having been joined.
  • the wear layer 8 should preferably not have any remaining gap between the boards. If the boards, after the joining, should become warped, or if the underlying floor is uneven, the boards can pivot in relation to one another about a point located at the top side of the hooks and the underside 6 of the recess 11. It is advantageous for this point to be located as high as possible, thus avoiding the creation of any gap in the wear layer if the angle between the boards is changed.
  • the widths of the hooks 1 and the intermediate slots 2 are the same. This may be varied as long as the heads 4 have a width corresponding to the slots 2.
  • the heads 4 (and the hooks 1) should be about 8 mm wide and the slots 2 (and the shoulders 7) should be about 10 mm wide. As the tenon at the short side is 6 mm, the displacement will be at least 6 mm. If the heads are made wider, e.g. 20 mm, the total surface locking the boards will be reduced.
  • the short sides of the boards may be provided with conventional groove-and-tenon joints. This is illustrated in Figs. 3, 4, 5 and 6 by a groove 10. The corresponding tenon is located at the other short end and thus is not visible.
  • the illustrated embodiment may be varied e.g. through modification of the thickness of the wear and carrier layers, the angles and configuration of the hook, the width and the length of the boards, etc., all of which should be obvious to a person skilled in the art.
  • the scope of the invention will only be limited by the appended claims.
