摘要： A header frame for a display system which is easily and quickly erected without tools and which is collapsible to a compact shape for packing, storage, and transport. The header frame is disassembled to only four portions for packing, storage, and transport, i.e., two frame portion assemblies and two elongate connector assemblies. Each of the frame portion assemblies comprises a plurality of members joined to be U-shaped when the header frame is erected and hingedly connected to be collapsible compactly so that the members are parallel to and lie alongside each other. Thumbscrews are provided for detachably attaching the connector assemblies to the frame portion assemblies so that tools are not required for erection or disassembly of the header frame.
