<p>Regards a coupling and supporting device of additional planes of an extensible table, where the additional planes are contained below the main plane, and they are extracted when they are to be used. Such device is characterised in that it comprises a mechanism substantially consisting of a pair of parallel rods, sliding into guides, applied below the main plane of the table. Such rods - when needed - are made to protrude from a side of the same table, usually from the side exhibiting a smaller length, so as to form the support of an additional plane. The main characteristic of the device according to the finding is that each of the two rods of each pair is provided, at its end, with a spring leverage which provides to coupling the additional plane and keeping it locked when it is aligned with the same main plane. <IMAGE></p> |
