Abstract

A block of springs for shaping mattresses and the like, characterized in that the block is constituted by a plurality of fundamental alignments, independent of each other, of spiral springs, each of which is formed by a single wire and in which each spring appears joined to the next one through a section of the wire itself that takes the form of "z", all these successive sections being located in correspondence with the upper and lower planes of the block, alternately and extending over said planes of shape its plant protrudes substantially on the periphery of the springs to the joining, being provided that said sections or areas in "z" are slightly overlapping at their ends in relation to its immediate the same row and overlapping at their vertices curved with respect to the corresponding vertices of the sectors in "z" of the adjoining rows, this last for etermining the connection points of each row with the next, which is accomplished by other helical wires of suitable diameter, which run parallel to the alignments of the fundamental and coincident springs with overlapping vertices of the rows determined, it being provided that all the spiral springs are curved in the same direction and that the greater surface amplitude presented by the sections or sectors in "z" of the wire itself, with respect to the springs that identify, is manifested only to one side of these and alternately, or on both sides and in an absolutely symmetrical way.
