Abstract
Abstract A box spring assembly in which the mattress support deck is supported by crosswires having integral, planar, sinuous end springs to provide improved peripheral support. Intermediate support springs are interwoven on the crosswires thus eliminating the need of retaining clips in assembly. The interweaving of the support springs on the crosswires allows the support springs, crosswires and integral sinuous end springs to act as a single entity. So constructed, the cost of manufacture is lowered and the ease of manufacture is increased.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
194 words
A box spring assembly comprising: a generally horizontal rectangular frame having a generally horizontal mattress support deck disposed a predetermined distance thereabove and formed of spring wire, said support deck including a border wire aligned substantially vertically with said frame, and a plurality of substantially straight wire members extending lengthwise of said frame and connected to said border wire; a plurality of crosswire members extending crosswise of said frame and being disposed a predetermined distance thereabove, said crosswire members having at opposite ends integrally formed end springs, said end springs being fixedly attached to said border wire and extending downward therefrom to said frame, each of said end springs being oriented in a substantially upright plane and being sinuous in shape and providing a desired stiffness to said border wire on opposite sides of said support deck, both said crosswire members and said end springs being formed of spring wire; and a plurality of intermediate deck support springs in interwoven engagement with said crosswire members and being arranged between said deck and said frame so as to yieldably support said deck on said frame, said intermediate springs further being fixedly attached to said frame.
Claim 2
Dependent Claim
194 words
A box spring assembly comprising: a generally horizontal rectangular frame having a generally horizontal mattress support deck disposed a predetermined distance thereabove and formed of spring wire, said support deck including a border wire aligned substantially vertically with said frame, and a plurality of substantially straight wire members extending lengthwise of said frame and connected to said border wire; a plurality of crosswire members extending crosswise of said frame and being disposed a predetermined distance thereabove, said crosswire members having at opposite ends integrally formed end springs, said end springs being fixedly attached to said border wire and extending downward therefrom to said frame, each of said end springs being oriented in a substantially upright plane and being sinuous in shape and providing a desired stiffness to said border wire on opposite sides of said support deck, both said crosswire members and said end springs being formed of spring wire; and a plurality of intermediate deck support springs in interwoven engagement with said crosswire members and being arranged between said deck and said frame so as to yieldably support said deck on said frame, said intermediate springs further being fixedly attached to said frame.
Claim 3
Dependent Claim
25 words
A box spring assembly as set forth in claim 1 wherein said intermediate deck support springs include a load bearing portion and a yielding portion.
Claim 4
Dependent Claim
32 words
A box spring assembly as set forth in claim 2 wherein said yielding portion is mounted at lower ends to said frame and terminates at upper ends in said load bearing portion.
Claim 5
Dependent Claim
38 words
A box spring assembly as set forth in claim 3 wherein said yielding portion has upwardly converging lower members, upwardly diverging upper members, and generally horizontally torsion bars connected at opposite ends to said upper and lower members.
Claim 6
Dependent Claim
31 words
A box spring assembly as set forth in claim 4 wherein said torsion bars are capable of abutting engagement with one another to thereby limit the deflection of said yieldable portion.

Dependent Claim
53 words
A box spring assembly as set forth in claim 2 wherein said load bearing portion includes torsion bars extending generally parallel to said straight wire members and under said crosswire members, a crossing member crossing over said crosswire members, and connecting members connecting said torsion bars to opposite ends of said crossing member.
Claim 8
Dependent Claim
21 words
A box spring assembly as set forth in claim 1 wherein said frame includes side rails, end rails, and cross rails.
Claim 9
Dependent Claim
18 words
A box spring assembly as set forth in claim 1 wherein said end springs are substantially vertically oriented.
Claim 10
Dependent Claim
21 words
A box spring assembly as set forth in claim 1 wherein said end springs include alternating substantially vertical and horizontal sections.
Claim 11
Dependent Claim
184 words
A box spring assembly comprising: a generally horizontal rectangular frame; a generally horizontal mattress support deck disposed a predetermined distance above said frame, said support deck including a border wire generally aligned with said frame, and a plurality of deck wires extending lengthwise of said frame and being connected at opposing ends to said border wire, said deck wires including integral sinuous end springs extending downward from said border wire to said frame; a plurality of spring units, each spring unit including a generally horizontal crosswire member extending crosswire of said frame and having at opposite ends thereof a pair of downwardly extending integral sinuous end springs, said sinuous end springs being secured to said frame at their lower ends and being secured to said border wire at their upper ends, each of said end springs being located in a substantially vertical plane extending downwardly from said border wire; and a plurality of limited deflection intermediate spring modules, said spring modules having an upper portion connected with said crosswire members and having a pair of downward extending yieldable portions fixedly attached to said frame.
Claim 12
Dependent Claim
184 words
A box spring assembly comprising: a generally horizontal rectangular frame; a generally horizontal mattress support deck disposed a predetermined distance above said frame, said support deck including a border wire generally aligned with said frame, and a plurality of deck wires extending lengthwise of said frame and being connected at opposing ends to said border wire, said deck wires including integral sinuous end springs extending downward from said border wire to said frame; a plurality of spring units, each spring unit including a generally horizontal crosswire member extending crosswire of said frame and having at opposite ends thereof a pair of downwardly extending integral sinuous end springs, said sinuous end springs being secured to said frame at their lower ends and being secured to said border wire at their upper ends, each of said end springs being located in a substantially vertical plane extending downwardly from said border wire; and a plurality of limited deflection intermediate spring modules, said spring modules having an upper portion connected with said crosswire members and having a pair of downward extending yieldable portions fixedly attached to said frame.
Claim 13
Dependent Claim
