摘要：A box spring assembly of the formed wire spring type comprising a plurality ofspring members mounted on a supporting frame and connected together to form aspring deck disposed above the frame and yieldably movable toward the frame. Some orall of the springs are of an improved construction wherein each consists of a substantiallyhorizontal body portion and depending end portions each of which comprises a pluralityof angularly arranged connecting bars and substantially horizontal torsion bars.Alternate ones of the connecting bars are substantially closer to being horizontal in theunloaded condition of the springs than the remaining ones of the connecting bars, theremaining ones of the connecting bars extending upwardly from the alternate ones sothat the remaining ones are more nearly vertical than the alternate ones. As a result,when the springs are subjected to downwardly directed loads, resistance to load isachieved by both twisting of the torsion bars and bending of some of the connectingbars.
