Box-spring assembly

Abstract

A box-spring assembly includes two frames, a resilient member, a plurality of lateral springs, and a plurality of clips. The frames are spaced apart from each other, and each of the frames has a looped lateral frame rod. The resilient member includes an array of spring coil units disposed between the frames, and a plurality of connecting elements connecting the spring coil units to each other. Each of the lateral springs is connected between the looped lateral frame rods so as to reinforce the looped lateral frame rods. The clips connect the spring coil units and the lateral springs to the looped lateral frame rods.

1 . A box-spring assembly, comprising:
 two frames spaced apart from each other and each having a looped lateral frame rod;   a resilient member including an array of spring coil units disposed between said frames, and a plurality of connecting elements connecting said spring coil units to each other;   a plurality of lateral springs each connected between said looped lateral frame rods so as to reinforce said looped lateral frame rods; and   a plurality of clips connecting said spring coil units and said lateral springs to said looped lateral frame rods.   
     
     
         2 . The box-spring assembly as claimed in  claim 1 , wherein each of said lateral springs includes two fastening end portions extending parallel to and fastened to said looped lateral frame rods correspondingly, a resilient helix portion between said fastening end portions, and two supporting portions each extending between a corresponding one of said fastening end portions and said resilient helix portion and oblique to said corresponding one of said fastening end portions. 
     
     
         3 . The box-spring assembly as claimed in  claim 2 , wherein each of said lateral springs is a one-piece bent metal rod that substantially resembles a figure of M. 
     
     
         4 . The box-spring assembly as claimed in  claim 1 , wherein each of said connecting elements is a metal wire that is coiled helically.
