Abstract: A pole sign construction comprising a vertical pole support;pairs of upper and lower brackets secured to the pole and having outwardly projecting aligned bolts; a pair of rectangular base sign boards of corrugated plastic material having a series of connecting holes formed in their lateral edges; a plurality of first clear plastic locking washers and clear plastic bolts connecting the corrugated sign boards in back-to-back relation around the vertical pole; spaced pairs of mounting holes formed in the upper and lower edges of each of the corrugated sign boards; locking washers securing the boards to the brackets on the projecting bolts, the bolts passing through the upper and lower mounting holes;overlay sign boards congruent with the base sign boards and secured to the plastic bolts with second clear plastic locking washers.

Abstract: A new and improved pole sign consisting of several simple but effective elements, namely, a one-piece upper sign engaging framing unit; an identical lower sign-engaging frame unit; and a laminated, flexible roll-up sign of sheet material which is gripped and mounted at its upper and lower edges in the aforementioned frame units; and a conventional strap mount for affixing said upper and lower frame units to a vertical pole. Where back-to-back units are desired for mounting on the same pole, the strap hardware simply affixes a pair of upper frame members and a pair of lower frame members in tandem to the mounting pole.

Abstract: A free-standing display system comprising a base, an upright post supported from the base and a plurality of shelves mounted on the post, is described. Each of the shelves has an opening dimensioned and shaped to fit freely around the post. The shelves are securely mounted on the post at desired height by means of wedges releasably held on the post by lugs which engage corresponding holes in the post. With the wedges in place, the shelf is moved downwardly around the post until the walls of the shelf opening, which are inclined to match the wedging surface of the wedges, snugly engage the wedging surfaces. Differently shaped and dimensioned shelves may be employed in the system and the shelf opening may be at the shelf centers or adjacent an edge. No tools are required to assemble or disassemble the shelves to the post. A header may be fastened to the upper end of the post, after the desired number of shelves are in place, to carry product identifying indicia or an advertising message.

Abstract: A display device comprises a rectangular transparent plastic envelope formed from two sheets of flexible plastic material which are seamed together adjacent their top, one side and bottom margins. The sheets also include horizontal enclosed sleeves at the top and bottom of the envelope in which tubular arms are located. Flexible coupling means are provided in engagement with the upper tubular arm while the lower tubular arm is engaged by laterally spaced tension means which permit the lower arm to turn ninety degrees with respect to the upper arm. A zipper-type closure means may be provided along the open side of the envelope to removably seal the envelope.
