Abstract
Abstract A spring and frame assembly, particularly for box springs for beds, consisting of a plurality of main springs arranged crisscross fashion on a rectangular supporting frame and internal support springs supported on the frame and secured to the main springs. Each of the springs has a resilient end portion mounted on the frame, and most of these end portions are constructed so that they terminate in mounting torsion bars which extend transversely of the frame members, thereby transmitting spring forces to the frame as compression forces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
210 words
A spring and frame assembly comprising a substantially horizontal rectangular frame, a plurality of spring-support members extending transversely of and supported on said frame, a plurality of substantially parallel transversely spaced first wire springs, each of said springs having a body portion and downwardly extending end portions, said springs being arranged so that said body portions are in a horizontally spaced relation, each of said end portions being disposed below said body portion and terminating in a mounting torsion bar, the mounting torsion bars at opposite ends of each said springs being engaged with the top side of one of said spring-support members at positions extending transversely thereof in a substantially centered relation therewith, a plurality of internal springs, each of said internal springs being secured to and extending between the body portions of adjacent ones of said first Springs, each of said internal springs including a body portion and end portions disposed below said body portion and terminating in mounting torsion bars which are supported on an adjacent pair of said spring-support members at positions substantially parallel to the first spring-mounting torsion bars engaged with said support members, and connecting means attaching said springs to said support members so as to maintain said mounting torsion bars in engagement therewith.
Claim 2
Dependent Claim
210 words
A spring and frame assembly comprising a substantially horizontal rectangular frame, a plurality of spring-support members extending transversely of and supported on said frame, a plurality of substantially parallel transversely spaced first wire springs, each of said springs having a body portion and downwardly extending end portions, said springs being arranged so that said body portions are in a horizontally spaced relation, each of said end portions being disposed below said body portion and terminating in a mounting torsion bar, the mounting torsion bars at opposite ends of each said springs being engaged with the top side of one of said spring-support members at positions extending transversely thereof in a substantially centered relation therewith, a plurality of internal springs, each of said internal springs being secured to and extending between the body portions of adjacent ones of said first Springs, each of said internal springs including a body portion and end portions disposed below said body portion and terminating in mounting torsion bars which are supported on an adjacent pair of said spring-support members at positions substantially parallel to the first spring-mounting torsion bars engaged with said support members, and connecting means attaching said springs to said support members so as to maintain said mounting torsion bars in engagement therewith.
Claim 3
Dependent Claim
128 words
A spring and frame assembly according to claim 1 wherein said frame has a pair of side rails arranged in a supporting relation with said spring-support members and a pair of end rails, and wherein said assembly further includes a plurality of substantially parallel transversely spaced second wire springs arranged substantially parallel transversely spaced second wire springs arranged substantially perpendicular to said first wire springs, each of said second wire springs having a body portion and downwardly extending end portions, means connecting the body portions in adjacent ones of said second wire springs to the same ones of said internal springs, and means connecting the end portions of said second wire springs to said frame end rails so that said end portions are in a supported relation thereon.
Claim 4
Dependent Claim
28 words
A spring and frame assembly according to claim 1 wherein said connecting means consists of staples extended across said mounting torsion bars and projected into said spring-support members.
Claim 5
Dependent Claim
48 words
A spring and frame assembly according to claim 1 wherein each of said end portions of said first and internal springs includes a plurality of torsion bars disposed in a substantially parallel relation with the torsion bars in the end portions of the remaining first and internal springs.
Claim 6
Dependent Claim
26 words
A spring and frame assembly according to claim 2 wherein said support members are arranged in a substantially equally spaced relation on said frame side rails.
Claim 7
Dependent Claim
137 words
A wire spring comprising a body portion adapted to be disposed in a plane and having a pair of ends, a pair of end portions formed integral with said ends of said body portion and extending downwardly from said body portion, each of said end portions including a torsion bar disposed in said plane at the juncture of said body and end portions, a plurality of torsion bars disposed below said juncture torsion bar, connecting bars extending between said torsion bars with at least some of said connecting bars being relatively inclined for movement toward and away from each other, and a mounting torsion bar at the lower end of each end portion, the mounting torsion bars for said spring being in a substantially parallel relation and being spaced apart predetermined distances both transversely and longitudinally thereof.
Claim 8
Dependent Claim
137 words
A wire spring comprising a body portion adapted to be disposed in a plane and having a pair of ends, a pair of end portions formed integral with said ends of said body portion and extending downwardly from said body portion, each of said end portions including a torsion bar disposed in said plane at the juncture of said body and end portions, a plurality of torsion bars disposed below said juncture torsion bar, connecting bars extending between said torsion bars with at least some of said connecting bars being relatively inclined for movement toward and away from each other, and a mounting torsion bar at the lower end of each end portion, the mounting torsion bars for said spring being in a substantially parallel relation and being spaced apart predetermined distances both transversely and longitudinally thereof.
Claim 9
Dependent Claim
43 words
A wire spring according to claim 6 wherein said body portion is formed at the ends thereof with substantially parallel attaching sections which are substantially perpendicular to said juncture torsion bars and are spaced apart in a direction transversely of said body portion.
Claim 10
Dependent Claim
178 words
In a spring and frame assembly which includes a substantially horizontal rectangular frame, a plurality of spring-support members extending transversely of and supported on said frame, and a plurality of main wire springs on said frame, each of said mainsprings having a body portion and downwardly extending end portions, said springs being arranged so that said body portions are disposed crisscross fashion in a substantially horizontal plane located above said frame, a plurality of internal springs, each of said internal springs including a body portion disposed substantially in said horizontal plane and end portions disposed below said body portion and terminating in mounting torsion bars which are supported on an adjacent pair of said spring-support members, the mounting torsion bars for each of said internal springs being substantially parallel to each other and extending transversely of said support members, connecting means attaching said springs to said support membErs so as to maintain said mounting torsion bars in engagement therewith, and means attaching the body portion of each of said internal springs to the body portions of adjacent mainsprings.
Claim 11
Dependent Claim
