Abstract

Extendable automatic table, characterized because it is composed of a tubular frame, in. The respective ends of which include bushings for coupling and fixing the legs that must support the assembly, anchor for this frame, somewhat elevated, a support for the fixed tabletop, which has. Some lugs in which reels are installed for stabilization of sliding or lateral slides formed by a rectangle devoid of one of its smaller sides, so that said slides extremely support, by means of articulated rods, forming a deformable parallelogram, to the lifting brackets that the extensible wings have to bear, said brackets relating to the runners, and in turn these to the fixed part of the table, by means of tension springs, whose effects provide the automatic extension and folding of the table and that in order to carry out the first operation it suffices to react of the wing or wings for once made by the runners, the total stroke, the extendable board to rise until it reaches the height of the fixed one, with which it will stop due to the force of the springs that try to attract it, who will be the one who, by oppressing said wing, will lightly introduce this part under the fixed central board, having been provided for greater ease and smoothness of movement, install on the crossbars of the main frame, two reels adjustable in height ..
