Device for lifting convertible table tops, characterized by being constituted by two extensible frames that are mounted transversely in the lower part of the table top, conveniently separated, and joined by a rod of appropriately threaded ends, in which, respectively, two nuts are mounted, arranged symmetrically, in each of which is fixed the end of a bar-compass, articulated at its ends in said nut and the upper bar of the frame, so that by rotating the rod by means of a suitable handle, the nuts move on the respective threaded areas transmitting the movement to said bar-bars that in turn raise or descend to the upper part of the frame, determining the appropriate movement of the board of elevation or descent according to the direction of rotation of the rod.
