F16F 3/00

US Classification:

5247, 5255, 5719, 267103

Abstract:

A support module for use in a bedding foundation to support a support surface above a bedding foundation base, the support module being of an independent wire form configured to define a top portion, a bottom portion, and four predominantly straight support legs, wherein the support legs are skewed with respect to each other, such that each respective support leg is not parallel to any of the other support legs. The top of each support leg is bent to be oriented into a common first plane to form the top portion, which may be connected to a wire grid assembly to form a nestable bedding foundation.

International Classification:

F16F 3/00
A47C 23/02

US Classification:

5247, 5255, 267103

Abstract:

A support module for a bedding foundation comprises two wire-form elements each a single length of wire configured to have a central bridge portion, two spaced legs extending in a common direction therefrom, and feet at terminal ends of the legs. The bridge portion the feet lie in parallel planes with the legs extending therebetween. The feet of one wire-form element are affixed to the bridge portion of the other wire-form element with the respective legs of both elements extending in a common direction and with the bridge portion of the one element and the feet of the other element in a common plane. The bridge portion of the other wire-form element is secured to a base of a bedding foundation and the feet of the other wire-form element and the bridge portion of the one wire-form element are secured to a support surface of a bedding foundation.

Hickory Springs Manufacturing Company - Hickory NC

International Classification:

A47C 27/04

US Classification:

5716, 5727, 5269, 5271

Abstract:

A spring cushion assembly for a one-sided mattress includes a plurality of spring coils. Each spring coil has a length of spring wire formed at opposite upper and lower ends in respective upper and lower end turns and in an intervening coil extent therebetween. The spring coils are characterized in that the lower end turns of each coil is closed by a knot formed between the lower wire end and the coil extent. The spring coils are further characterized in that the upper end turn of a first selected number of the spring coils is open with the upper wire end unknotted to the coil extent and the upper end turn of a second selected number of the spring coils is closed by a knot formed between the upper wire end and the coil extent.

International Classification:

F16F 300
A47C 2302

US Classification:

267103

Abstract:

A nestable box spring foundation includes support modules each formed of a single length of wire defining a top base, a bottom base, and four straight legs. The top base is welded to a wire grid assembly and includes two upper wire segments each having a straight wire portion and respective first and second curved end portions, each upper wire segment lying in a first plane with the straight wire portions lying in angularly converging mirror image relation to each other, each upper wire segment being spaced from one another with first end portions thereof lying closer together than second end portions thereof. The bottom base includes two straight lower wire segments lying in parallel relation to and in a second plane with one another and a straight cross wire segment fixedly intersecting orthogonally the lower wire segments proximate first ends thereof, with the first plane being parallel with the second plane. A first leg extends from the first end portion of an upper wire segment to a second end of a lower wire segment, a second leg extends from the first end portion of the other upper wire segment to a second end of the other lower wire segment; a third leg extends from the second end portion of the first upper wire segment to a first end of the cross wire segment; and a fourth leg extends from the second end portion of the second upper wire segment to a second end of the cross wire segment.

International Classification:

F16F 300

US Classification:

267103

Abstract:

A wire spring module and wire grid for use in a furniture spring assembly for mounting an array of multiple spring modules to the wire grid and the resulting furniture spring assembly. The wire grid includes a plurality of straight, coplanar wires arranged in a first sub-plurality of parallel spring placement wires and a second sub-plurality of parallel spring seating wires extending in generally perpendicular relation to the spring placement wires, the spring seating wires being arranged in a plurality of seating wire pairs with the spring seating wires of each seating wire pair disposed at a first predetermined spacing from one another and with each seating wire pair disposed at a second greater predetermined spacing from each seating wire pair adjacent thereto. The unitarily-formed wire spring module comprises a generally coplanar top and a pair of legs extending from opposite ends of the top and in spaced relation to one another. The top is comprised of a pair of generally J-shaped end segments arranged in spaced reverse mirror image relation to one another and connected together by an intermediate straight segment.
