Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
127 words
An article display system comprising a post having a plurality of openings therein angularly spaced around the periphery of said post at a predetermined position along its length, means for supporting said post in an upright position, a shelf having an article supporting surface and an opening therethrough dimensioned and shaped to fit freely around said post, wedge means for mounting said shelf on said post, said wedge means including a plurality of wedge members each having a lug extending from one surface thereof, said lug adapted to be inserted into one of said openings in said post to releasably secure said wedge members to said post, said wedge means adapted to snugly engage said shelf within said opening to support said shelf firmly on said post.
Claim 2
Dependent Claim
127 words
An article display system comprising a post having a plurality of openings therein angularly spaced around the periphery of said post at a predetermined position along its length, means for supporting said post in an upright position, a shelf having an article supporting surface and an opening therethrough dimensioned and shaped to fit freely around said post, wedge means for mounting said shelf on said post, said wedge means including a plurality of wedge members each having a lug extending from one surface thereof, said lug adapted to be inserted into one of said openings in said post to releasably secure said wedge members to said post, said wedge means adapted to snugly engage said shelf within said opening to support said shelf firmly on said post.
Claim 3
Dependent Claim
30 words
The article display system of claim 1 further including header means adapted to be secured to the upper end of said post and including surfaces adapted to carry advertising messages.
Claim 4
Dependent Claim
159 words
An article display system comprising: a post having a plurality of openings therein, a base for supporting said post in an upright position, at least one shelf having an article supporting surface and an opening therethrough dimensioned and shaped to fit freely around said post, and wedge means for mounting said shelf on said post, said wedge means including a plurality of like wedge members, each of said wedge members having a post-engaging side and an inclined surface opposite said post-engaging side, and at least one lug extending from said post-engaging side adapted to be received in one of said openings in said post, said wedge members thereby being adapted to be individually releasably secured to said post at a predetermined position along its length and at angularly spaced locations around the periphery thereof, said wedge means being adapted to snugly engage said shelf within said opening to support said shelf firmly on said post at said predetermined position.
Claim 5
Dependent Claim
159 words
An article display system comprising: a post having a plurality of openings therein, a base for supporting said post in an upright position, at least one shelf having an article supporting surface and an opening therethrough dimensioned and shaped to fit freely around said post, and wedge means for mounting said shelf on said post, said wedge means including a plurality of like wedge members, each of said wedge members having a post-engaging side and an inclined surface opposite said post-engaging side, and at least one lug extending from said post-engaging side adapted to be received in one of said openings in said post, said wedge members thereby being adapted to be individually releasably secured to said post at a predetermined position along its length and at angularly spaced locations around the periphery thereof, said wedge means being adapted to snugly engage said shelf within said opening to support said shelf firmly on said post at said predetermined position.
Claim 6
Dependent Claim
106 words
The article display system of claim 3 wherein the inclined surface of each of said wedge members diverges outwardly from top to bottom and the opening in each said shelf is defined by downwardly diverging walls for engaging each of the inclined surfaces of said wedge members, whereby with said wedge members secured to the post and the upper end of the post extending through the opening in the shelf, the shelf may be moved downwardly along the post to bring the diverging walls of said opening into engagement with the inclined surfaces of said wedge members, thereby to secure said shelf at said predetermined position.
Claim 7
Dependent Claim
45 words
The article display system of claim 4 wherein openings for receiving the lugs on said wedge members are provided at spaced intervals along the length of said post whereby one or more of said shelves may be mounted at different desired heights on said post.
Claim 8
Dependent Claim
55 words
The article display system of claim 5 wherein said post is polygonal in cross-section and the opening in said shelf is correspondingly polygonal in shape, the openings in said post for receiving the lugs of said wedge members being disposed in a plurality of the flat surfaces of said post at each shelf supporting position.
Claim 9
Dependent Claim
41 words
The article display system of claim 6 wherein said post cross-section and said shelf opening are square in shape and a wedge member is adapted to be secured to each of the four sides of said post for supporting each shelf.
Claim 10
Dependent Claim
29 words
The article display system of claim 4 wherein each of said wedge members includes an elongated foot portion extending outwardly of said inclined surface along the bottom edge thereof.
Claim 11
Dependent Claim
39 words
The article display system of claim 8 wherein each of said wedge members include a pair of lugs extending perpendicularly from the post-engaging side thereof and said lugs and said foot portion are integrally formed with said wedge member.
Claim 12
Dependent Claim
