Abstract: The table leg system meant for being blocked against the tabletop or against a set of tables combined in modules, characteristic in the fact that the upper end of the table leg system is equipped with a case (1) over the assembly mechanism, perpendicular to the longitudinal axis of the leg to which the casing (24) with formed hallows (27) is screwed from the side of the tabletop. It is also characteristic in the fact that in the case (1) there are the levers' (3) and (4) rotating axes in relation to the case (1) itself, and the levers (3) and (4) are on both ends terminated with fastening, blocking tangs (5) and (6) perpendicular to the lever (3) and (4) and one of the ends of each of the levers is attached to an oscillating hinged connector (7) which has a pivot handle (8) installed at the other end.
