Abstract

A nestably stackable bedding foundation assembly which replaces the traditional border wire and disposed coil spring foundation assembly in a so-called box spring. The nestably stackable foundation assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping.

Claims

1. A nestably stackable assembly for use in a bedding foundation comprising

a rectangular border wire having two parallel sides and two parallel ends, said parallel sides being longer than said parallel ends,

transversely-spaced, parallel, and longitudinally-extending support wires parallel to said border wire sides and having ends connected to said border wire ends, said support wires being formed so as to be generally corrugated along their lengths, said corrugatedly formed support wires having peaks and valleys, said peaks and valleys being flattened at their extrememost locations, said flattened peaks being generally coplanar with a plane defined by said border wire, said flattened valleys being vertically displaced beneath and intermediate of said flattened peaks,

longitudinally-spaced, parallel, and transversely-extending upper connector wires parallel to said border wire ends and having ends connected to said border wire sides, said upper connector wires being connected intermediate of their ends along their lengths thereof to said flattened peaks of said support wires, and

longitudinally-spaced, parallel, and transversely-extending lower connector wires parallel to said border wire ends and having ends connected to said flattened valleys of said outboardmost support wires, said lower connector wires being connected intermediate of their ends along their lengths to said flattened valleys of said support wires between said outboardmost support wires.

2. The nestably stackable assembly of claim 1 wherein longitudinal voids between said flattened peaks are of a dimension greater than said flattened valleys.

3. The nestably stackable assembly of claim 2 being a first assembly, which, when placed atop a second assembly of like construction, is nestedly stacked thereon when said flattened valleys of said first assembly enter into said voids between said flattened peaks of said second assembly, said nested assemblies having a total heighth dimension less than a sum of a heighth dimension of said first assembly and a heighth dimension of said second assembly.

4. A nestably stackable assembly for use in a bedding foundation comprising

a rectangular border wire having two parallel sides and two parallel ends,

transversely-spaced, parallel, and longitudinally-extending support wires parallel to said border wire sides and having ends connected to said border wire ends, said support wires being formed so as to be generally corrugated along their lengths, said corrugatedly formed support wires having peaks and valleys, said peaks being flattened at their tops, said flattened peaks being generally coplanar with a plane defined by said border wire, said valleys being vertically displaced beneath and intermediate of said flattened peaks, and

longitudinally-spaced, parallel, and transversely-extending upper connector wires parallel to said border wire ends and having ends connected to said border wire sides, said upper connector wires being connected intermediate of their ends along their lengths to said flattened peaks of said support wires.

5. A bedding foundation comprising

a rectangular base,

a nestably stackable wire core assembly fixedly attached atop said base,

a foam pad overlying said nestably stackable assembly, and

a fabric covering overlying said pad and surrounding said nestable assembly and base;

said nestably stackable assembly comprising

a rectangular border wire having two parallel sides and two parallel ends,

transversely-spaced, parallel, and longitudinally-extending support wires parallel to said border wire sides and having ends connected to said border wire ends, said support wires being formed so as to be generally corrugated along their lengths, said corrugatedly formed support wires having peaks and valleys, said peaks being flattened at their tops, said flattened peaks being generally coplanar with a plane defined by said border wire, said valleys being vertically displaced beneath and intermediate of said flattened peaks, and

longitudinally-spaced, parallel, and transversely-extending upper connector wires parallel to said border wire ends and having ends connected to said border wire sides, said upper connector wires being connected intermediate of their ends along their lengths to said flattened peaks of said support wires.
