Abstract
Abstract A mattress box spring and method of assembly comprising a plurality of substantially conical coil springs rigidly fastened at the spring ends of lesser diameter to a support frame such that the spring end coils of greater diameter lie in a substantially common plane, a wire mesh coated with elastomeric material overlying the end coils in the common plane with the spring end coils being unattached or free-floating with respect to the mesh and with respect to each other, and a cloth cover or pad disposed over the mesh and having a periphery attached to the frame to hold the assembly together. Preferably, the diameter of each spring end coil lying in the common plane is greater than the corresponding spring height. The coating on the wire mesh, which preferably is of latex material, provides enhanced frictional contact between the mesh and springs, and also deadens rattling between the opposing spring and mesh surfaces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
A method for constructing box springs or the like comprising the steps of attaching one end of a plurality of coil springs to a frame such that the other end of each said spring lies in a substantially common plane, locating a mesh having a border wire around the periphery thereof over said springs in said substantially common plane such that said other ends of said springs are free-floating with respect to said mesh and with respect to each other, locating a cover over said mesh such that a periphery of said cover encompasses said border wire, and attaching said cover periphery to said frame.
Claim 2
Independent Claim
105 words
A method for constructing box springs or the like comprising the steps of attaching one end of a plurality of coil springs to a frame such that the other end of each said spring lies in a substantially common plane, locating a mesh having a border wire around the periphery thereof over said springs in said substantially common plane such that said other ends of said springs are free-floating with respect to said mesh and with respect to each other, locating a cover over said mesh such that a periphery of said cover encompasses said border wire, and attaching said cover periphery to said frame.
Claim 3
Dependent Claim
37 words
The method set forth in claim 1 comprising the further step of pulling said cover taut over said mesh and springs such that said springs are slightly compressed when said cover periphery is attached to said frame.
Claim 4
Independent Claim
103 words
A method of constructing box springs or the like comprising the steps of attaching one end of a plurality of coil springs to a frame such that the other end of each said spring lies in a substantially common plane, placing a cover over a work surface, placing a mesh having border means around the periphery thereof over said cover, placing said attached frame and springs over said mesh such that said springs lie on said mesh and are unattached thereto and said border means is aligned with a periphery of said frame, and attaching a periphery of said cover to said frame.
Claim 5
Independent Claim
103 words
A method of constructing box springs or the like comprising the steps of attaching one end of a plurality of coil springs to a frame such that the other end of each said spring lies in a substantially common plane, placing a cover over a work surface, placing a mesh having border means around the periphery thereof over said cover, placing said attached frame and springs over said mesh such that said springs lie on said mesh and are unattached thereto and said border means is aligned with a periphery of said frame, and attaching a periphery of said cover to said frame.
Claim 6
Dependent Claim
27 words
The method set forth in claim 1, 2 or 3 further comprising the step of providing a layer of resilient elastomeric material between said mesh and springs.
Claim 7
Dependent Claim
28 words
The method set forth in claim 4 wherein said step of providing said layer comprises the step of precoating said mesh with a skin layer of elastomeric material.
Claim 8
Dependent Claim
18 words
The method set forth in claim 5 wherein said precoating step comprises the step of dip-coating said mesh.
Claim 9
Dependent Claim
14 words
The method set forth in claim 6 wherein said layer is of latex material.
Claim 10
Dependent Claim
18 words
The method set forth in claim 7 wherein said layer is on the order of 1/64 inch thick.
Claim 11
Dependent Claim
31 words
The method set forth in claim 1 or 3 wherein the diameter of said other ends of said springs is equal to or greater than the height of each said spring.
Claim 12
Dependent Claim
40 words
The method set forth in claim 9 wherein said springs comprise substantially conical springs, said step of attaching said springs to said frame comprising the step of attaching an end of lesser diameter of each said spring to said frame.
