ABSTRACT:
BACKGROUND OF THE INVENTION
I. Field of the Invention
The present invention relates to improved display systems for holding display graphics including panels, photomurals, banners, signs or the like in tension and in a generally upright, but angularly adjustable, position and particularly to a collapsible lightweight system that is easily assembled with the item to be displayed or collapsed for transport or storage. The display system can be used indoors as a stand alone support or outdoors with a stake-down system or stabilizing counter weights.
II. Related Art
There often exists a need to provide a temporary or portable device for displaying a photomural or other information carrying banner or sign that is readily deployed to support and display a relatively large sign and yet can be collapsed into a lightweight, easily carried compact form for transport and storage. Such a device would find advantageous use in retail sales displays, trade shows, fairs, lawn signs or the like to provide a variety of information to those in view of it. Certain types of signs have been devised that are portable and at least to some extent collapsible.
One type of collapsible, multi-faceted, self-supporting systems with opposed displays is shown by Zeigler (U.S. Pat. No. 4,970,841) in which panels are held together in a back-to-back arrangement. Other collapsible systems are depicted in U.S. Pat. No. 4,700,498 to Perutz et al and U.S. Pat. No. 5,203,126 to Sorenson et al. Scissor connectors are used to interconnect a plurality of vertical frame units in Weinrub et al (U.S. Pat. No. 5,269,112).
While existing devices have certain attributes and provide a degree of flexibility and portability in display signs, there remains a need for a lightweight, durable, fully collapsible system that deploys from a knock-down transport or storage state to accommodate a variety of banners or photo-murals readily. There also exists a need for such a system in which a plurality of different banners or murals can be interchangeably displayed in a variety of combinations of multiple panels using the same frames to form a variety of larger multiple-frame displays of various configurations. There also would be an advantage if the size of the display frame could be varied to accommodate a variety of display sizes.
Accordingly, it is a primary object of the present invention to provide a versatile, lightweight, durable, readily deployed, readily collapsible display support system for a banner or photomural display panel that combines in a variety of configurations to accommodate a variety of banners.
A further object of the invention is to provide a lightweight, durable, readily deployed, readily collapsible display support system for a plurality of banner or photomural display panel units in which a variety of banners or photomurals can readily be accommodated on panels joined together in a manner that enables at least some individual panels to be pivoted relative to each other to form triangles, winged shapes and any number of other display shapes.
Another object of the present invention is to provide such a multi-panel display support system in which the posture of any display panel is variable and easily adjusted.
Still another object of the present invention is the provision of a collapsible self-supporting display panel unit of adjustable size.
Yet another object of the present invention is to provide such a display panel support system that is relatively rugged and economical.
A still further object of the invention is to provide a lightweight, durable, readily deployed, readily collapsible display support system for a plurality of banner or photomural display panels in which the banners or photomurals can be displayed in one or more directions.
A yet still further object of the invention is to provide a lightweight, durable, readily deployed, readily collapsible display support system for a plurality of banner or photomural display panels in which the banners or photomurals can be displayed a single direction consecutively in line.
Other objects and advantages associated with the display panel support system of the invention will become apparent to those skilled in the art upon further consideration of this specification, drawings and appended claims.
SUMMARY OF THE INVENTION
The present invention provides compact, lightweight, self-contained support systems that are easily deployed to carry and support one or more photomurals, banners, signs or the like under tension and that readily collapse to rather small sizes for transport and storage. As used herein, the terms “banner” or panel or photomural, etc. are defined to include all possible types of display articles susceptible of mounting using the support system of the invention.
The display support systems of the invention may take a variety of forms using relatively few interchangeable parts making them extremely versatile and easy to manufacture. The system may be constructed of segments of strong, light weight aluminum alloy tube connected using slip fittings, connecting hub devices and other unique parts. Other materials including other metals and polymeric materials or fiberglass may also be used for the rod segments. Connectors and hub devices may be machined from metals or made of any dimensionally stable material including cast, molded or otherwise processed polymer materials such as polyamides, for example. Successful parts here been made from various nylons.
In some cases, portions of the rods or other parts may be of solid construction. The parts may be snap-fit together using a variety of fittings. However, the panel support systems or individual units are generally made up of a plurality of hollow tube segments connected by one or more internal resilient cord (bungee) systems that allow easy assembly and disassembly (knock down) for transport or storage in a relatively small container. The support units can be sized to carry one or more rectangular banners of any size or shape or a banner of any other configuration capable of being tensioned between such spaced parallel tubes. The system is very light weight and, for example, a single 4′×8′ banner support of aluminum alloy may weigh less than a pound.
One single-banner embodiment incorporates a pair of spaced hollow mounting tubes which carry opposite edge loops of the banner threaded over the tubes. In an assembled system, the banner is carried on and between the mounting rods, spaced apart, the banner held in tension by a pair of hollow strut members crossed to form an X-bracing arrangement. The struts are made up from a plurality of slip-fit sections which combine to form elongated flexible tubular members which, when assembled in place, cross behind the banner and hold the mounting tubes in spaced parallel relation the flexible rods being somewhat longer than the transversal distance of the assembled structure and so assuming a bowed shape when connected to the mounting tubes. Both ends of each of the flexible struts of the X-bracing include terminal pins which are designed to be accommodated in openings in corresponding resiliently held hub members slip fitted into the ends of the spaced hollow mounting rod members. The openings in the hubs are elongated toward the surface to accommodate the struts over a range of angles between hub and strut. The X-bracing flexible strut members themselves are adjustably constrained at the intersection where they cross behind the banner by a central strap or loop member which allows relative displacement of the intersection along the X-bracing strut members.
Each hub end of one hollow mounting tube member, i.e., the one which carries the lower edge loop of the banner, and becomes the lower hollow mounting rod member in the combined structure, is also resiliently connected to one end of one of a pair of hollow base tube members, the other ends of which converge to intersect and form the legs of an isosceles triangle support base with the lower mounting tube member. The intersection of the base legs is connected by a hollow stabilizing tub
