Panel for producing a free-lying floor covering

A panel having a shape of a plank or a tile for a production of a floor covering, the panel comprising two pairs of opposed sides defining:

• a first two opposed edges for inclined assembly with adjacent panels, wherein one edge comprises male coupling provided from a lateral wall of the panel, and an opposed edge comprising complementary female coupling provided from a lateral wall of the panel;
• a second two opposed edges for vertical assembly with adjacent panels, wherein one edge comprises male coupling provided from a lower face of the panel, and an opposed edge comprising complementary female coupling provided from an upper face of the panel;
• wherein:
• the male coupling of the edges for the vertical assembly comprise a male groove extending along the edge and opening onto the lower face of the panel to define a male tenon, the male tenon having an outer wall and an inner wall both inclined with respect to a vertical plane and towards the outside of the panel at an angle of between 1° and 15°;
• the female coupling of the edges for the vertical assembly comprise a female groove extending along the edge and opening onto the upper face of the panel to define a female tenon;
• the male coupling of the edges for the vertical assembly comprise a lug or a notch and the female coupling of the edges for the vertical assembly comprise a complementary notch or lug forming, after assembly of two adjacent panels, abutment stops to counteract a vertical displacement between two adjacent assembled panels.
