INTERNAL ELASTIC SUMMER ASSEMBLY

摘要

Internal structure of box spring. /P P The closed end turns of classic vertical box spring springs are connected to each other by horizontal coil springs wound around their contiguous sections & These sections are on the one hand offset outwards with respect to the rest of these turns, on the other hand sinuous so as to form projections which, superimposed on those of the contiguous section of the neighboring turn, limit the movement of the turns thus assembled pivoting relative to each other. Application to the bedding industry.
