Abstract:
An improved thermal drapery construction to provide two thermally resistant air spaces behind a decorative drapery without increasing the bulk or stack when the drapery is pulled off the glass. The construction consists of hanging a three part thermal drapery consisting of a backing material with fibrous spacer and a material metallized on two sides from a wide tape that suspends the three part combination under a carrier on a retaining rod. The combination material is slightly thinner than the carrier so an air space is created between the thermal drapery and a decorative drapery that is attached to the opposite side of the same carrier. The air space between the two draperies is also increased by a recalculation of the spacing of the carrier fastening means on the headings of the two draperies.A critical feature of the thermal drapery is the means of assembly that makes it fold in regular reverse folds so that it enhances the appearance of the folds of the outer drapery. The means of assembly also allows the material to be uniformly opaque.Additional improvements have been made to the heat-cap and support brackets to facilitate installation of the heat cap and retainer rod or rods. The thermal drapery has a design feature that allows a sheer curtain to be hung behind the drapery with no danger of the outer drapery crushing the inner when the outer drapery is opened and closed.
Abstract:
A thermally protective drapery construction comprises retaining rod means and inner and outer panels of drapery material arranged in suspended, separated relationship on the retaining rod means. The separated drapery panels are supported in a manner such that a thermally resistant critical air spacing is provided and extends between the panels and at a substantially uniform value. In the case of folds of respective inner and outer panels which are moved toward and away from one another along the retaining rod means, uniformity of the spacing is maintained during such movement.The critical air spacing consists of a thermally resistant air space provided by locating the panels apart from one another a distance lying in a range of from 0.25 inches up to approximately 0.5 inches. Such a spacing between upper portions of the inner and outer panels of drapery material is achieved by securing together the panels with snap fastening carriers on the retaining rod and snap fastening tapes secured to the panels and attached to the carriers in spaced apart relation. Intermediate and lower portions of the inner panel also have fastened thereto fibrous separator means. The separator means may be of a thickness co-responding to the above-noted critical air spacing and extend into contact with the outer panel. The retainer rod means includes a heat cap attached by bracket means to a wall surface and located in closely spaced relation to upper edges of the drapery folds to constitute an air baffle which is maintained in effect when the drapery folds are opened and closed. The inner panel has a vertical edge seal which is also maintained when the inner and outer drapery folds are opened and closed and which permits access to a cord and pulley located between the panels without breaking the edge seal.
