Wire mesh pad for mattress box springs

Claim 2

A wire mesh pad for a box spring unit using torsion bar springs which comprises two side border members, each of said side border members including a metal rod having a coating selected from the group consisting of paper and plastic, a plurality of wire elements extending transversely between said side border members and having their ends attached thereto, said transverse wire elements being made from a material selected from the group consisting of oil-tempered spring steel and high strength steel, said wire elements being spaced from one another in the range of about 3/4 to 1 3/4 inches and having a tensile strength greater than 200,000 lbs. per square inch, said wire elements being mounted on said torsion bar springs upon assembly of said box spring unit, and paper cords extending parallel to said side border members and attached to said wire elements to maintain the position of said wire elements relative to one another.

Claim 3

The wire mesh pad of claim 1 wherein said metal rods have a diameter in the range of about 0.0625 to 0.162 inches and a tensile strength greater than 200,000 lbs. per square inch.

Claim 4

The wire mesh pad of claim 1 wherein said wire elements have a diameter in the range of about 0.023 to 0.062 inches.

Claim 5

The wire mesh pad of claim 1 wherein the wire elements at each end of said pad have been distorted to shorten their length so that they are still taut where said side border members curve toward one another to conform to the contour of the corners of a box spring unit.

Claim 6

In a mattress box spring utilizing torsion bar springs wherein a wire mesh pad is placed on said torsion bar springs and a layer of padding is placed on said wire mesh pad and said box spring is enclosed in suitable fAbric, the improvement comprising a wire mesh pad comprising two side border members, each of said side border members including a metal rod, said metal rod being coated with material selected from the group consisting of paper and plastic, a plurality of wire elements extending transversely and tautly between said side border members and having their ends attached thereto, said transverse wire elements being made of a material selected from the group consisting of oil-tempered spring steel and high strength steel, said wire elements being spaced from one another in the range of about 3/4 to 1 3/4 inches and having a tensile strength greater than 200,000 lbs. per square inch, said wire elements being mounted on said torsion bar springs, and paper cords extending parallel to said side border members and attached to said wire elements to maintain the position of said wire elements relative to one another.

Claim 7

In a mattress box spring utilizing torsion bar springs wherein a wire mesh pad is placed on said torsion bar springs and a layer of padding is placed on said wire mesh pad and said box spring is enclosed in suitable fAbric, the improvement comprising a wire mesh pad comprising two side border members, each of said side border members including a metal rod, said metal rod being coated with material selected from the group consisting of paper and plastic, a plurality of wire elements extending transversely and tautly between said side border members and having their ends attached thereto, said transverse wire elements being made of a material selected from the group consisting of oil-tempered spring steel and high strength steel, said wire elements being spaced from one another in the range of about 3/4 to 1 3/4 inches and having a tensile strength greater than 200,000 lbs. per square inch, said wire elements being mounted on said torsion bar springs, and paper cords extending parallel to said side border members and attached to said wire elements to maintain the position of said wire elements relative to one another.

Claim 8

In the mattress box spring of claim 5 wherein said metal rods have a diameter in the range of about 0.0625 to 0.162 inches and a tensile strength greater than 200,000 lbs. per square inch.

Claim 9

In the mattress box spring of claim 6 wherein said wire elements have a diameter in the range of about 0.023 to 0.062 inches.

Claim 10

In the mattress box spring of claim 5 wherein said box spring has rounded corners, the ends of said border members curving toward one another to conform to said corners, said wire elements attached to said curved portions being distorted to reduce their length so that they remain taut.
