ABSTRACT:
A space divider and method for making same, the space divider comprising a peripheral frame, having at least two portions lying in different planes and a fabric sleeve stretched over and entirely covering the peripheral frame, forming at least two double-curvilinear surfaces. The peripheral frame may comprise side rail members and a plurality of braces connecting the rail members. The fabric sleeve may be impregnated with a resinous material, thereby providing a substantially rigid omni-directional sound reflecting and dispersing surface, or left soft, with fill or padding optionally disposed between opposite surfaces of the fabric sleeve, thereby providing a omni-directional sound absorbing surface. The fabric sleeve may be a one-piece, two-way stretch member, such as different types of knitted materials or a non-stretch member of different types of woven materials. The space dividers are easily shaped in keeping with the requirements of space and sound control by stretching the fabric over a designed contour, thereby providing an inexpensive means for producing customized articles on a large scale. The space divider can also be filled with a thermal mass for temperature control.
