Definitions

  • the present invention pertains generally to plastic composite material springs for use as flexible elements in weight bearing structures, and more particularly for use in flexible human weight bearing structures such as bedding and seating and furniture .
  • torsional steel spring formed from heavy gauge steel spring wire bent into multiple continuous sections which deflect by torsion when compressed. See for example U.S. Patent Nos. 4,932,535; 5,346,190 and 5,558,315. Because torsional springs are dimensionally larger and stiffer than compression springs, fewer torsional springs are needed in the foundation. However, the manufacture of torsional-type springs from steel wire requires very expensive tooling and bending equipment. Elaborate progressive bending dies are required to produce the complex torsional spring module shapes which may include four or more adjoining sections.
  • FIG. 6C is an elevation view of a spring module of the invention engaged with a frame member and a grid in a mattress foundation of the present invention
  • FIG. 2 illustrates one embodiment of a low profile mattress foundation of the invention having a plurality of composite material spring modules 16 constructed in accordance with the invention.
  • the foundation 10 includes a novel low profile frame, indicated generally at 12 which supports a plurality of composite material spring modules
  • the assembly of the composite material mattress foundation system is highly flexible and greatly simplified by the relatively small size and simple geometry of the spring modules.
  • the spring modules 16 may be attached to the inner frame members (such as frame members 22) before or after attachment of the inner frame members to the other frame members .
  • the spring modules are secured to the frame members by insertion of the key 37 through the frame member key hole and rotated 90 degrees to a locked position.
  • the number of spring module attachment points (e.g., holes for receiving keys 37) will determine the maximum number of modules which one frame member can support.
  • a single frame member may include as many as forty module or more attachment points, though only twenty or fewer evenly spaced modules may be attached in the assembly process .
