Abstract
A low profile composite material bedding foundation system and methods of manufacture and assembly uses spring modules made of molded composite materials and supported by inner frame members. The low-profile of the spring modules, and the composite material spring property of return to uncompressed state from total depth deflection without set, greatly decreases the height of the bedding foundation in which the spring modules are attached directly to foundation frame members. The small size and simple geometry of the spring modules is especially suited for flexible arrangement and automated assembly of low-profile foundations.
Claims28
A low profile composite material bed foundation comprising,
- a frame including frame perimeter members and inner frame members arranged within said frame perimeter members,
- a plurality of individual spring modules made of composite material, each spring module separately attached at the point to said inner frame members, and
- a mattress support structure in the form of a grid attached at two upper points of each of said spring modules, whereby each of said individual spring modules is compressible in response to a force applied to said mattress support structure.
A bed foundation for use as a support structure for a sleeping mattress, the bed foundation comprising:
- a generally rectilinear frame,
- a plurality of inner frame members attached to said rectilinear frame,
- a plurality of individual composite material spring modules, each spring module separately attached at a lower point to said inner frame members, and each spring attached at two upper points to a grid supported in a horizontal plane above said spring modules, said grid providing a generally horizontal planar mattress support surface, and said composite spring modules providing deflectable support for said grid.
A low profile mattress foundation support structure, the foundation comprising:
- a generally rectangular frame defined by connected length and width perimeter members,
- a plurality of inner frame members attached to and within said generally rectangular frame,
- a plurality of individual spring modules made of composite material and attached at one point to said inner frame members and attached at two points to a grid disposed in a plane parallel to a plane in which said rectangular frame and said inner frame members are disposed, whereby said grid is flexibly supported at a distance from said rectangular frame and inner frame members by said plurality of individual spring modules.
A low profile bed foundation for use as a deflectable support structure for a sleeping mattress, the foundation comprising:
- a rectilinear frame formed by orthogonally connected length and width perimeter members,
- elongate inner frame members each having an upper and lower area, ends of the inner frame members attached at the lower area to the rectilinear frame and spanning the frame from one perimeter member to an opposite perimeter member,
- a plurality of spring modules made of composite material, each of said spring modules having a center section attached to an upper area of an inner frame member and an end section on either side of the center section, the end sections of each spring module attached to a grid positioned parallel to the frame, whereby the end sections of each of the spring modules are deflectable in response to forces exerted upon the grid.
A composite material spring module for use as a supporting element in a bedding foundation system, said composite material spring module having a substantially linear configuration and being attachable at one point to an inner frame member and a grid of a bedding foundation.
