Abstract
Abstract An improved wire grid for connecting an array of coil springs in a box spring assembly includes perpendicularly-connected lengthwise-extending and widthwise-extending wires with the widthwise-extending wires arranged in sufficient number of possible groupings, each of three successively adjacent wires, spaced along the length of the grid to enable the grid to accept plural differing arrays of coil springs by utilizing varying combinations of the wire groupings for use of the grid without modification in box spring assemblies having differing spring-supporting base frame constructions.

Claim 1
Independent Claim
302 words
A wire grid for connecting an array of coil springs supported in a box spring bedding assembly on a plurality of transverse slats arranged in spaced parallel relation longitudinally along the box spring bedding assembly to form a base frame thereof, said wire grid being characterized by the capability of being selectively alternatively used for connecting at least two differing arrays of differing numbers of coil springs in at least two respective differing box spring assemblies having differing numbers of transverse slats at differing longitudinal spacings from one another without requiring structural modification of said wire grid, said grid comprising a plurality of relatively rigid longitudinal wires arranged in spaced parallel relation to one another and a plurality of relatively rigid transverse wires arranged in spaced parallel relation to one another and rigidly connected to said longitudinal wires in substantially perpendicular relation thereto, said longitudinal and transverse wires collectively forming said grid in an overall rectangular configuration, said transverse wires being arranged at selected spacings from one another forming a plurality of groupings of said transverse wires immediately adjacent one another and the respective transverse wires of each said grouping being cooperative with one another for connection thereto of a plurality of coil springs laterally spaced across the width of said grid, said groupings being of a number and being arranged at differing longitudinal spacings relative to one another in correspondence to the collective number and spacings of the respective transverse slats of said two box spring assemblies to be capable of selective alternative use in either of said two differing box spring assemblies for connecting either of said at least two differing arrays of coil springs without structural modifications of said wire grid, selected ones of said transverse wires being arranged to form a part of two different adjacent groupings thereof.
Claim 2
Dependent Claim
302 words
A wire grid for connecting an array of coil springs supported in a box spring bedding assembly on a plurality of transverse slats arranged in spaced parallel relation longitudinally along the box spring bedding assembly to form a base frame thereof, said wire grid being characterized by the capability of being selectively alternatively used for connecting at least two differing arrays of differing numbers of coil springs in at least two respective differing box spring assemblies having differing numbers of transverse slats at differing longitudinal spacings from one another without requiring structural modification of said wire grid, said grid comprising a plurality of relatively rigid longitudinal wires arranged in spaced parallel relation to one another and a plurality of relatively rigid transverse wires arranged in spaced parallel relation to one another and rigidly connected to said longitudinal wires in substantially perpendicular relation thereto, said longitudinal and transverse wires collectively forming said grid in an overall rectangular configuration, said transverse wires being arranged at selected spacings from one another forming a plurality of groupings of said transverse wires immediately adjacent one another and the respective transverse wires of each said grouping being cooperative with one another for connection thereto of a plurality of coil springs laterally spaced across the width of said grid, said groupings being of a number and being arranged at differing longitudinal spacings relative to one another in correspondence to the collective number and spacings of the respective transverse slats of said two box spring assemblies to be capable of selective alternative use in either of said two differing box spring assemblies for connecting either of said at least two differing arrays of coil springs without structural modifications of said wire grid, selected ones of said transverse wires being arranged to form a part of two different adjacent groupings thereof.
Claim 3
Dependent Claim
64 words
A wire grid for a box spring assembly according to claim 1 and characterized further in that said wire groupings are more closely spaced relative to one another in a central region along the length of said grid than in end regions at the opposite ends of said grid to permit a greater concentration of coil springs to be mounted in said central region.
Claim 4
Dependent Claim
36 words
A wire grid for a box spring assembly according to claim 1 and characterized further in that each said wire grouping is arranged for interlocking engagement with an end coil of each coil spring mounted thereon.
Claim 5
Dependent Claim
29 words
A wire grid for a box spring assembly according to claim 3 and characterized further in that each said wire grouping comprises a set of three adjacent transverse wires.
Claim 6
Dependent Claim
28 words
A wire grid for a box spring assembly according to claim 1 and characterized further in that said transverse wires provide at least eleven groupings of adjacent wires.
Claim 7
Dependent Claim
28 words
A wire grid for a box spring assembly according to claim 1 and characterized further in that said transverse wires provide at least thirteen groupings of adjacent wires.
Claim 8
Dependent Claim
28 words
A wire grid or a box spring assembly according to claim 1 and characterized further in that said transverse wires provide at least fifteen groupings of adjacent wires.
