Abstract
Abstract A foldable bed including at least two frame parts hingedly interconnected for folding movement toward and away from another between an extended in-use position and an upright storage position, there being a series of coil springs each connected at one end at similar intervals along the inner sides of the frame parts so as to be arranged in opposed pairs, a plurality of transverse resilient metal bands interwoven transversely of the major axis of the bed in extended position, at least two longitudinal resilient metal bands extending uninterruptedly from end to end of said frame parts, each band being connected to two coil springs and the longitudinal bands being interwoven with the transverse bands except those adjacent said hinge means so that when the frame parts are folded toward one another the longitudinal bands fold about such a radius of curvature as to prevent undue stressing or kinking.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
In a foldable bed, a frame means including at least two parts, hinge means about which the parts can fold toward and away from one another between an extended in-use position and an upright storage position, a spring-support means including a plurality of coil spring units connected to the frame means at one of their ends and spaced around the inner periphery thereof, and a plurality of transverse resilient metal bands interwoven transversely of the major axis of the frame in extended position and at least two longitudinal resilient metal bands extending uninterruptedly from end to end of said frame means, each band being connected to two coil spring units and the longitudinal bands being interwoven with said transverse bands except those adjacent said hinge means so that when the frame parts are folded toward one another, they fold about such a radius of curvature as to prevent undue kinking.
Claim 2
Dependent Claim
150 words
In a foldable bed, a frame means including at least two parts, hinge means about which the parts can fold toward and away from one another between an extended in-use position and an upright storage position, a spring-support means including a plurality of coil spring units connected to the frame means at one of their ends and spaced around the inner periphery thereof, and a plurality of transverse resilient metal bands interwoven transversely of the major axis of the frame in extended position and at least two longitudinal resilient metal bands extending uninterruptedly from end to end of said frame means, each band being connected to two coil spring units and the longitudinal bands being interwoven with said transverse bands except those adjacent said hinge means so that when the frame parts are folded toward one another, they fold about such a radius of curvature as to prevent undue kinking.
Claim 3
Dependent Claim
20 words
A foldable bed as claimed in claim 1 in which said transverse metal bands are arranged diagonally of the bed.
Claim 4
Dependent Claim
132 words
A foldable bed as claimed in claim 1 in which said coil spring units include a series of coil springs each connected at one end at similar spaced intervals along the inner sides of the frame parts so as to be arranged in opposed pairs, said transverse metal bands comprising two sets of equilength bands connected between the coil spring of one pair on one side of the frame and the opposite coil spring of the next adjacent pair on the other side of the frame, the bands of one set crossing the bands of the other set on the same side thereof so that each coil spring is connected to one band of each set whereby weight applied to any band is distributed through the coil springs to the other bands.
Claim 5
Dependent Claim
181 words
The foldable bed as claimed in claim 1 in which said two frame parts comprise a pair of generally U-shaped members, at least three U-shaped and shorter leg members, hinge brackets connecting the spaced-apart ends of two of the leg members to the first-mentioned U-shaped members, said hinge means comprising hinge bracket means connecting the ends of the first-mentioned U-shaped members to the ends of the other leg member so that the frame can be extended to dispose the first-mentioned U-shaped members in facing aligned relation with the leg members extending downwardly therefrom and folded to dispose the first-mentioned U-shaped members in spaced-apart parallel relation with the first two leg members folded against the first-mentioned U-shaped members and the third leg member between such U-shaped members, and said transverse metal bands each being connected at one end to one coil spring and at its other end to a diagonally arranged coil spring with the bands crossing one another in series from one end of the frame to the other, there being at least two bands connected to each side coil spring.
