    Abstract: There is provided a multi-purpose collapsible structure comprising a structure housing having front and base peripheral edges adjoined to each other. The structure housing has front and base apertures which are elongated adjacent the front and base peripheral edges, respectively. Front and base flexible rods are extended within the front and base apertures, respectively. The structure housing further has a biasing member disposed at each location where the front and base rods converge toward each other to engage the rods therewith. Each of the biasing members maintain the front rod generally perpendicular to the base rod in an extended position whereby the front rod is movable thereto via application of force opposing the biasing members. This forms a stowed position and collapse the structure housing.

    Abstract: An acoustic medium for temporary acoustic treatment of a room is formed from one or more continuous curtains, preferably, with pleated first and second major surfaces. Each pleated curtain preferably has one or more series of collapsible elongated tubular sections which form the pleats that make up the major surfaces of the curtain. Since the elongated tubular sections are collapsible, the curtain can be retracted by collapsing the elongated tubular sections and extended by opening the elongated tubular sections. The mat materials forming the elongated tubular sections and the pleated major surfaces of the curtain provide the curtain with an airflow resistance through the curtain, in a direction generally perpendicular to the planes containing the apexes of the pleats forming the first and second major surfaces of the curtain, that has the desired properties for absorbing or reflecting sound.

    Abstract: A colinear laminate honeycomb panel permits the use of two or more different materials to form a single panel. In this manner, a retractable cover for an architectural opening may be formed that has a different appearance depending upon which side of the panel is being viewed. The resultant panel is formed by attaching a plurality of elongated precursor tubular cells, wherein each precursor tubular cell itself comprises at least two strips of material held in proximity to one another by a common carrier strip.

  • Patent number: 6068903
    Abstract: Pop-up items are provided which can either be mounted in three-dimensional form on a suitable supporting surface by means of pressure-sensitive adhesive carried by the item or can be affixed to facing panels of a letter or pages of a book. Some preferred items include a pop-up element in the form of one or two panels carrying strategically located pressure-sensitive adhesive which permits instant mounting, e.g. between facing panels so that, upon opening, the pop-up element assumes a three-dimensional configuration as a result of the pressure-sensitive adhesive bonding to the surfaces of facing panels or pages. The 3-dimensional pop-up can also be mounted to a suitable supporting surface. A variety of methods for the mass production of such pop-up elements from a continuous web, e.g., a printed and die-cut web from a web press, facilitate their inexpensive fabrication. These pop-up elements are preferably marketed or distributed in groups, e.g.

  • Patent number: 6054194
    Abstract: An improved mathematically modeled family of bellow fold patterns, useful for making bellows from stiff but foldable materials, which forms a corner of a bellow consisting of a series of several single inversion fold patterns, each having a characteristic design angle which is mathematically computed to provide a desired initial wall angle for the bellow and to minimize wall tilting over a predetermined extension angle range, thereby allowing low cost bellows to be made which can extend long distances while using a minimal amount of stiff but foldable material.

  • Patent number: 6052966
    Abstract: A retractable cover for an architectural opening is described that includes a honeycomb insulating panel wherein each cell of the panel has multiple layers of material formed by embedding tubular cells. In this manner, the retractable cover may be formed that has superior insulating or light blocking capabilities in a volume comparable to one with a honeycomb panel made of tubular cells having a single layer of material. The panel of the resultant cover is formed by attaching a plurality of embedded tubular cell units, wherein each embedded tubular cell unit comprises at least one side having multiple layers of material.

  • Patent number: 6048591
    Abstract: An ornament includes a collapsible housing constructed preferably of polyvinyl chloride and provided with an air valve allowing of selective inflation and deflation of the housing. Contained within the interior of the housing is a tethered figurine, along with a measured amount of particulate material simulating snowflakes. By employing foamed polystyrene as the particulate material, a composition is utilized which exhibits a natural affinity towards clinging to the inner wall of the housing. Upon inflation of the housing, which includes a hanger formation at its top, the figurine is displayed as a freely suspended member within the housing while the particles of foamed polystyrene are attracted to and cling to the wall of the housing in a scattered or random manner. The material of the housing may be transparent or alternatively, be translucent with a slight degree of opacity.

  • Patent number: 6001434
    Abstract: Decorative structures comprising a flexible sheet-like member simulate universal conceptions of the appearance of floating and fixed ghosts. A structure for simulating a universal conception of the appearance of a floating ghost comprises a flexible sheet-like member draped over a support member, such as a balloon, to form a composite structure. The composite structure is suspended from a support structure to simulate the appearance of a floating ghost. A decorative structure for simulating a universal conception of a fixed ghost comprises a support bag member having a filling therein, and a flexible sheet-like member placed over the support bag member and having facial indicia simulating an appearance of a face of a ghost thereon. The free ends of the sheet-like member are secured to the ground at spaced apart positions, to provide a generally inverted conical shape, so that the resultant structure can flutter when subjected to wind or the like.
