Abstract: The invention is a quick-release connector to be used with a collapsible display frame structure as taught in U.S. Pat. No. 4,658,560. The invention permits quick coupling and release between a rear and front hub as taught in U.S. Pat. No. 4,627,210. During use, the quick-release connector provides a solid lock when mounted in a coupled position with a hub. The release of the connector from a coupled position occurs upon movement of a slidable sleeve. A spring maintains contact between the slidable sleeve and the connector collar during coupling. Engagement of the slidable sleeve separates the sleeve from the collar permitting the connector to be pulled free from the hub. A split housing couples the connector to the hub. A spring-loaded slidable sleeve maintains the split housing in a locked position. The rear end of the connector is releasably mounted to a hub of a collapsible display frame structure.

Abstract: A graphic display panel system formed in sections, wherein a graphic display image may be affixed to each section, the sections respectively having transparent edge caps and/or hinge connectors and/or locking pin assemblies for selectively interconnecting the sections to form an overall surface. The individual panel sections may be formed of a lightweight honeycomb structure or spaced apart plastic sheets.

Abstract: An improved hinge for portable multi-panel display systems, wherein the display system is formed by a plurality of individual composite panels having a cellular paperboard core the periphery of which has a relatively rigid, higher-density edging. The edging is adapted to receive either a flexible hinge for linking panels or an edge trim piece to form a finished periphery for a display system. The flexible hinge is a living hinge with two webs having parallel lines of weakness.

Abstract: A fabric-covered hinged connector for flat display panels with fabric exteriors. The hinged connector includes caps formed of semi-rigid PVC and having opposing channel portions and tapered ends which are integrally connected with an elongate hinge formed of flexible PVC. The exterior surface and a large portion of the interior surface of the hinge connector are overlaid with fabric. A display panel is inserted into each of the channel portions. The paired display panels may thus be oriented at numerous angles relative to each other while the hinge connector itself is concealed by the fabric. The semi-rigid caps and flexible hinge piece are integrally formed simultaneously in one extrusion process.

Abstract: An interlocking panel system having individual thin-walled sections, each section being supported by a rectangular frame formed of edge strip material. Each edge strip is constructed with an outwardly facing interlocking channel, to permit interlocking engagement of hinges and other connectors. The system includes a flexible hinge assembly which has outer edges shaped to slidably engage into the edge strips, and locking levers for indexing and affixing the respective flexible hinges in locked relationship to the panel sections. The edge strips also have selectively positioned locating holes and a slidable bar is movable into position along the edge strips, to permit the attachment of locating pins and feet for the various panel sections.

Abstract: A platform frame assembly for attachment to a portable exhibit display, the platform frame assembly having pivotal display frame members which are engageable against the portable exhibit display in an interlocking arrangement; the platform frame assembly having a plurality of horizontal shelves supportable by the frames for providing a projecting platform as an attachment to the portable exhibit display.

Abstract: A lightweight portable one-piece beam for attachment to a portable display structure and including two triangular, elongate, tubular portions running along elongate edges of the beam for lending stability to the beam. The beam is convertible from its stable folded form with tubular portions to a flat, portable form.

Abstract: An improved coupler for use in assembling display frames is provided. The coupler includes a male plug, a female receptacle and a locking lever. After insertion into frame members, the plug and receptacle are engaged and locked in place. The coupler enables a frame which can be assembled and disassembled by hand and which provides a smooth, finished appearance having no outstanding protrusions.

Abstract: A lightweight portable display support incorporating a display panel, including two vertical support columns, each column formed of two sections of elongated flexible material, typically plastic, wherein one section of material has a width dimension larger than the second section of material, both sections of material having an attachment device extending along their respective elongate edges to cause the wider section of material to bow outwardly when attached to the narrower section, and including an overhead horizontal beam supported between the two vertical support columns, the beam being constructed substantially the same as the respective vertical columns.

Abstract: A lightweight portable beam for attachment to a portable display structure by a simple hanging bracket, the beam formed of two pieces of elongated flexible material, typically plastic, wherein one piece of material has a width dimension larger than the second piece of material, both pieces of material having an attachment device extending along their respective elongate edges, to cause the wider material piece to become bowed outwardly when attached to the narrower piece.

Abstract: A lightweight knockdown table and cabinet structure adapted for ease of assembly and disassembly comprised of a plurality of hollow tubular frame members releasably interconnected by a plurality of fasteners and lock assemblies and having a multi-sectioned top which adds rigidity and support to the structure. The fastener and lock assemblies each include a fastening device with multiple end connectors. The fastening devices are slidably insertable into the frame members and have a guide slot bridging into a locking slot. The end connectors are also insertable into the frame members and have a projecting male connector end. The male connector end is insertable into the guide slot and movable into locking engagement within the locking slot to releasably interlock the frame members together at right angles. The multi-sectioned top includes adjacent middle and side sections with support flanges which rest upon opposing frame members.

Abstract: A fastening device for use in support structures wherein the fastening of support members is accomplished by slidably inserting end connectors into slotted fastening devices to produce a final locking fit between the support members and the fastening device. A keyed screw which holds the fastening device and support member in an intermediate locking position to aid in the overall assembly of the support structure.

Abstract: A box-like display header that is foldable to a flat orientation for transportation and storage. The header is mountable to an upper portion of a display frame and may include a fluorescent lamp to illuminate the display frame or provide a back lighting for various graphic symbols which may be imprinted on the display header.

Abstract: A portable display case formed in three sections, having hinging strips interconnecting the respective sections, the hinging strips each having a center line of perforations for facilitating bending, and also having a parallel line of perforations equally spaced on either side of the center line of perforations, the distance between the parallel lines of perforations being substantially equal to the thickness of the center section of the three sections.

Abstract: A first reflexively collapsible support and attachment structure for use in portable self-supporting frames for display panels, walls, podiums and tables. A horizontal elongate foot having front and back ends forms the base. Connected to the front end of the foot is a first brace adapted to swing to an inclined position. A biased support strut is provided between the foot and the first brace. The support strut is slidably collapsible and supports the first brace in the inclined position. Second and subsequent braces are interlockingly hinged such as to swing to generally vertical positions. Aligned in parallel fashion is a second like reflexively collapsible structure. The first and second structures are interconnected by at least two horizontal connecting rods. Display panels or sheets are connected between the first and second structures.
