ABSTRACT:
The transformable low drawing-room table of the invention comprises a bearing surface formed by four upper flat rectangular, side by side arranged, elements which are equal to one another, overlapping according to the same direction and suitably hinged on two lower flat rectangular, side by side arranged, elements which are equal to each other and have the same length as the upper flat elements while being each twice the width of one of them.
The assembly of said upper and lower flat elements is supported by a pair of bearing M-shaped members each comprising two outer vertical legs integral with slanting central braces forming a "V" and carrying inside an eccentric sliding guide for support arms of the bearing surface. The slide of the arms upwardly in the oblique direction causes the bearing surface to be raised as well as the lower flat elements to be moved away from each other together with the associated upper flat hinged elements overlapping them to a predetermined extent equal to the width of the upper flat elements.
Engagements are provided to lock the arms in the raised position. Stiffening means are also provided, which are disposed crosswise under the lower flat elements and which comprise telescopic extension means supporting the upper flat elements.
