Claims

1. A system for connecting along the adjacent edges (3, 4) of the joint of two building panels (1, 2), especially floor panels, in which the adjacent edges (3, 4) of the joint together form the first mechanical connection fastening the edges (3, 4) of the joint with each other in the first direction (D1) at right angles to the main plane of the panels (1, 2), and the locking device (6, 8, 14) on the rear side (18, 16) of the panels (1, 2) forms a second mechanical connection securing the panels (1, 2) to each other in the second direction (D2) parallel to the main plane and at right angles to the edges (3, 4) a joint, and the locking device (6, 8, 14) contains a locking groove (14), which runs parallel to and is located at a distance from the edge (4) of the joint of one (2) of the panels, called a panel with a groove, and which is open on the rear side (16) of the panel (2), characterized in that the locking device (6, 8, 14) further comprises a strip (6) made integrally with another (1) of panels called a panel with a strip, moreover, the strip ( 6) extends essentially along the entire length of the edge (3) of the junction of the panel (1) with the bar and is equipped with a locking element (8) protruding from the bar and so that when the panels are joined together, the strip (6) protrudes on the back side of the grooved panel (2) with its locking element (8) received by the locking groove (14) of the grooved panel (2) that the panels when they are joined together , can occupy a relative position in the second direction (D2), where there is a gap (Δ) between the locking groove (14) and the fixing surface (10) on the locking element (8), which faces the edges of the joint and is effective in the second mechanical connection that both the first and second mechanical joints The positions are made with the possibility of mutual displacement of the panels (1, 2) in the direction of the edges (3, 4) of the joint, and that the second mechanical connection is made in such a way that allows the locking element (8) to leave the locking groove (14), if the panel (2) with the groove is turned around its edge (4) of the connection (4) at an angle to the side of the panel (6).

2. The system according to claim 1, characterized in that when the panel (2) with a groove is pressed against the panel (1) with the bar in the second direction (D2) and rotated at an angle to the side from the bar (6), the maximum distance between the axis of rotation panels (2) with a groove and a locking surface of the locking groove (14) closest to the edges of the joint is such that the locking element (8) can leave the locking groove (14) without contact with the locking surface of the locking groove (14).

3. The system according to claim 1 or 2, characterized in that the fixing surface (10) of the locking element (8) protrudes from the front side (22) of the bar (6) to a height in the first direction, which is less than or equal to 2 mm.

4. The system according to any one of paragraphs. 1 to 3, characterized in that the first mechanical connection is formed by the edge (4) of the panel junction (2) with a groove engaged in the first direction between the edge (3) of the panel junction (1) with the bar and the front side of the bar.

5. The system according to any one of paragraphs. 1 - 4, characterized in that the strip (6) is made in one piece with the panel (1) of a material different from the material of the panel (1), and is fixedly attached to the panel (1) at the factory.

6. The system according to claim 5, characterized in that the strip (6) for at least one or two panels (1, 2) is received in the recessed groove (40, 42) on the rear side (18, 16) of this one panel (12).

7. The system according to claim 5 or 6, characterized in that the strip (6) is installed in the alignment groove (40), which is recessed on the rear side (21) of the panel (1); that the part of the strip (6) protruding beyond the panel (2) with the groove is inserted into the corresponding leveling groove (41), which is recessed on the rear side (16) of the panel (2) with the groove and has the same exactly specified distance (E) from its lower part to the front side (26) of the panel (2) with a groove, and that the strip (6) has at least such a height that the rear side (44) of the strip is flush with the rear sides (18,16) of the panels.

8. The system according to claim 7, characterized in that the strip (6) has such a thickness that it is only partially accepted by the alignment grooves (40, 42).

9. The system according to any one of paragraphs. 5 to 8, characterized in that the strip (6) is attached to the panel (1) with the strip through mechanical connection.

10. The system according to claim 6, characterized in that the mechanical connection between the strip (6) and the panel (1) with the strip contains a gripping edge (52) formed by two recesses (24, 50) on the rear side (18) of the panel with the strip protrusions, flanges or the like (54, 56) that are bent or knocked out of the bar (6) and which are pressed against the opposite outer sides of the gripping edge (52).

11. The system according to claim 6, characterized in that the mechanical connection between the strip (6) and the panel (1) comprises a recess (58) on the rear side (18) of the panel with the strip, and protrusions, flanges or the like, bent or knocked out of the bar (6) and which are pressed against the opposite inner sides of the recess (58).

12. The system according to any one of paragraphs. 5 to 11, characterized in that the strip (6) is attached to the panel (1) using a binder.
