Abstract
The invention relates to a joining system and method for floorboards, panels and sheaves, but foremost for parquetry. The system comprises boards intended to be joined together, wherein a first board has a groove fitting with a tenon in a second board. According to the invention, the first board (A) has has a groove (2) provided with a rib on the top side of a lower edge, and the second board (B) has a tenon (1) provided with a ridge on the underside. A cut (3) is provided in the lower corner of the groove. The cut (3) makes the lower edge of the groove more flexible and can also take up excessive glue. Through this, the joining will be very simple to perform, whilst at the same time providing a strong joint.
Claims22
A joining system for floor boards, comprising boards (A, B) intended to be joined with each other, wherein a first board (A) has a groove (2) provided with a rib (4) on the top side of a lower edge, and a second board (B) has a tenon (1) provided with a ridge (6) on the underside, and wherein a cut (3) is provided in the lower corner of the groove (2).
A board for a joining system, having a groove (2) on a first long side of the board, and a tenon (1) on a second long side of the board, wherein the groove (2) is provided with a rib (4) on the top side of a lower edge and the tenon (1) is provided with a ridge (6) on the underside, thus allowing identical such boards to be joined with each other, and wherein a cut (3) is provided in the lower corner of the groove (2).
A method of joining floor boards, using boards (A, B) intended to be joined with each other, wherein a first board (A) has a groove (2) provided with a rib (4) on the top side of a lower edge, and a second board (B) has a tenon (1) provided with a ridge (6) on the underside, and wherein a cut (3) is provided in the lower corner of the groove (2), comprising the steps of:
- laying a first board (A) in place;
- laying a second board (B) next to board (A) in such a way that the tenon (1) is located straight in front of the groove (2) of board (A);
- forcing the boards together, thereby letting the ridge (6) on the tenon (1) pass over the rib (4) pressing the lower edge (5) of the groove downward;
- and, when the tenon has passed into the groove (2), letting the lower edge (5) spring back locking the ridge (6) behind the rib (4).
