Abstract
Abstract A portable, free-standing sight and sound barrier comprises a covered core of a lightweight, resilient foam. The core is flexible because it has alternating wall and hinge portions. The hinge portions are thinner parts of the core, generally being between about 3/8-1/2 inch thick. Suitable core materials are polyethylenes, polystyrenes, urethanes, or mosaic composites of these foams. Suitable coverings are fabrics, foils, paper, or paints, depending on the particular use contemplated for the barrier.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A portable, free-standing sight and sound barrier comprising: (a) an integral core of a lightweight, resilient foam which possesses cushioning and sound-absorbing properties, the core having alternating wall and hinge portions of foam defining a length of the barrier, the hinge portions allowing the barrier to assume smoothly curving configurations while the wall portions remain substantially straight and erect between successive hinge portions, each wall portion having a thickness sufficient to support the barrier when the barrier is placed on end, each hinge portion being defined by aligned pairs of grooves in spaced, substantially parallel array, each pair of grooves extending along the entire width of the barrier from end to end substantially perpendicular to the longitudinal axis of the barrier and impending by tapered side walls to substantially equal depths from opposite faces of the wall portions to form a thinned resilient hinge portion which is equally flexible in both directions; and (b) a fabric cover adhered to the foam over the wall and hinge portions to cover substantially the entire surface of the foam, the cover being adapted to provide additional strength and resiliency for the hinge portions.
Claim 2
Dependent Claim
190 words
A portable, free-standing sight and sound barrier comprising: (a) an integral core of a lightweight, resilient foam which possesses cushioning and sound-absorbing properties, the core having alternating wall and hinge portions of foam defining a length of the barrier, the hinge portions allowing the barrier to assume smoothly curving configurations while the wall portions remain substantially straight and erect between successive hinge portions, each wall portion having a thickness sufficient to support the barrier when the barrier is placed on end, each hinge portion being defined by aligned pairs of grooves in spaced, substantially parallel array, each pair of grooves extending along the entire width of the barrier from end to end substantially perpendicular to the longitudinal axis of the barrier and impending by tapered side walls to substantially equal depths from opposite faces of the wall portions to form a thinned resilient hinge portion which is equally flexible in both directions; and (b) a fabric cover adhered to the foam over the wall and hinge portions to cover substantially the entire surface of the foam, the cover being adapted to provide additional strength and resiliency for the hinge portions.
Claim 3
Dependent Claim
23 words
The barrier of claim 1 in which the core is about two inches thick and the hinge portion is about one-half inch thick.
Claim 4
Dependent Claim
17 words
The barrier of claim 1 in which the foam material of the hinge portions is not crushed.
Claim 5
Dependent Claim
50 words
The barrier of claim 1 in which the longitudinal side edge portions of the core are also covered with fabric strips adhered to the foam, the longitudinal side edges of said strips being cut away at the hinge portions of the core to match the end profile of the core.
Claim 6
Dependent Claim
26 words
The barrier of claim 4 in which at least one vertical end of said core is connected to a wood end cap covered by the fabric.
