ABSTRACT:
A portable display frame combination is claimed which provides a display combination which is easy and quick to assemble, sturdy and portable. The combination comprises a support frame, a plurality of support devices attached vertically to the display frame and a plurality of display panels attached to the support devices. The support devices are each comprised of a plurality of individual bars which telescope into one another for ease of storage and transport. As the bars are telescopically expanded, unique connection pieces cause each of the inner bars to snap forward to provide a smooth support surface disposed in a single plane. The connection pieces are made up of a forward section and a rearward section, the rearward section is affixed to one end of the inner bar. The forward section is separated from the rearward section by a spring in such a way that the forward section can be compressed toward the rearward section by applying pressure to the forward section. The forward section has a first portion which is affixed flush with the inner bar and a second section which is recessed from the first section by a distance equal to the thickness of the wall of the outer bar. As the inner bar is drawn out of the outer bar, the spring causes the forward section to snap forward so that the inner bar and the first section of the connection device are flush with the outer bar.
