Claims

1. A floor system comprising a plurality of rectangular floor panels (1, 2) that are mechanically connected to each other in parallel rows, respectively, along adjacent long edges (3, 4) and short edges (3 ', 4') panels, wherein said floor panels are provided with means for mechanically joining together their long edges (3, 4), as well as their short edges (3 ', 4') in the first direction (D1) at right angles to the main plane of the panels, thereby forming the first mechanical connection between the panels (1, 2), characterized in that each panel on its rear side is provided with: (1) a locking bar (6, 6 ′) on one long edge (3) and one short edge (3 ′), each locking bar (6, 6 ′) made integrally with the panel (1, 2) and forms a continuation of the lower part of the corresponding edge of the panel (1, 2) runs essentially along the entire length of the corresponding edge of the panel, and is equipped with a protruding locking element (8), and (ii) locking a groove (14, 14 ') on the opposite long edge (4) and on the opposite short edge (4'), each locking groove (14, 14 ') runs parallel and at a distance from the corresponding edge (4, 4 ') and is open on the rear side of the panel, while the locking strips (6, 6') and the locking grooves (14, 14 ') form a second mechanical connection that joins the panels to each other in the second direction (D2) parallel to the main plane and at right angles to the connecting edges (3, 4; 3 ', 4'), so that the strip (6, 6 ') of the first of the two connected panels protrudes on the rear side of the second panel, and its locking element (8) is placed in the locking groove (14 14') of the second panel (2), that the first mechanical connection is made with the possibility of mutual movement of the panels (1, 2) in the direction of the long edges (3, 4), that the panels, being connected along their long edges (3, 4), can occupy a relative position in the specified second direction (D2 ) at which there is a gap (Δ) between the locking groove (14) and the fixing surface (10) on the locking e element (8), which is facing the long edges (3, 4), so that the second mechanical connection also allows mutual movement of the panels (1, 2) in the direction of the long edges (3, 4), that the second mechanical connection along the long edges ( 3, 4) is configured to exit the locking element (8) from the locking groove (14) by turning (2), to which the locking groove (14) belongs, around its long edge (4) in the angular direction from the strip (6), and that each locking bar (6 ') on the short edges (3', 4 ') is elastic and resilient, so that two panes spruces (1, 2), which are already mechanically connected to the common long edge of the third panel, can be mechanically connected together at their adjacent short edges (3 ', 4') by shifting the two panels horizontally towards each other, while elastically bending the elastic the bar (6 ') on one (3') of the indicated short edges down until the specified adjacent short edge (4 ') of the two panels (1, 2) comes into full engagement with each other in a horizontal position, and the locking element (8 ) on the indicated short edge (3 ') will not enter with the latch the obtainable locking groove (14 ') at the second short edge (4').

2. The floor system according to claim 1, characterized in that the first mechanical connection, as well as the second mechanical connection along the long edges (3, 4), are configured to enter the locking element (8) into the locking groove (14) if the panel (2 ), to which the groove (14) belongs, is rotated around its connecting edge (4) in an angular direction to the bar (6) while holding the upper part of the connecting edge (4) of the panel (2) to which the groove belongs, in contact with the upper part of the connecting the edges (3) of the adjacent panel (1) to which the bar belongs.

3. The floor system according to claim 1 or 2, characterized in that the first mechanical connection, as well as the second mechanical connection along the long edges (3, 4), are arranged to allow the locking element (8) to enter the locking groove (14) if the panel (2) to which the groove belongs is rotated around its connecting edge (4) in an angular direction from the strap (6) while holding the upper part of the connecting edge (4) of the panel (2) to which the groove belongs, in contact with the upper part of the connecting the edges (3) of the adjacent panel (1) to which the plan belongs ka.

4. The floor system according to any one of p. 1-3, characterized in that for the elastic deflection of the elastic strip (6 ') down while simultaneously displacing these adjacent short edges (3', 4 ') horizontally towards each other, these adjacent short edges (3 ', 4') are provided with interacting upper and lower chamfers (70, 72), so that the panels (1, 2) are forced to move vertically towards each other when adjacent short edges (3 ', 4') move up to each other , and the panels (1, 2) are compressed together in the horizontal direction.

5. The floor system according to any one of paragraphs. 1-4, characterized in that the fixing surface (10) of the locking element (8) extends from the front side (22) of the strip (6, 6 ') in the indicated first direction at a height that is less than or equal to 2 mm

6. The floor system according to any one of paragraphs. 1-5, characterized in that the locking element (8) consists of a locking edge extending continuously along the strip (6, 6 ').

7. The floor system according to any one of paragraphs. 1-6, characterized in that the lower layer (46) of floorboards, polystyrene foam, felt, etc. attached to the rear sides (18, 16) of the panels.

8. The floor system according to claim 7, characterized in that the lower layer is attached so as to close the strip (6, 6 ') in the specified second direction, at least until the locking element (8), so that the connection between the lower layers ( 46) two adjacent panels (1, 2) are offset in the indicated second direction with respect to the connecting edges (3, 4, 3 ', 4').

9. The floor system according to any one of paragraphs. 1-8, characterized in that the sealing means, for example, a sealing mixture, a sealing strip or the like. it is provided on the front side (22) of the strip (6, 6 ′) between the locking element (8) and the connecting edge (3, 3 ′) of the panel (1) to which the strip belongs, for sealing with another panel (2).
