Abstract
Abstract A plurality of identical, reversible, rectangular display panels each has two cylindrical column members along one-half of the length of opposite sides, the panels being arranged side-by-side to form a display unit with the column members on one panel axially aligned with and pivotally attached to the column members of the two adjacent flanking panels by connector pins extending into the adjacent end sections of the members. Individual cylindrical extension members telescoped with the fixed frame members provide continuations of the column members along the other half of the panel edge of the end panels of the display unit. The panels forming the unit are supported vertically by tubular cylindrical legs having upright shanks received in the lower ends of the column members, and the support legs, column members and extension members appear as continuous panel supporting columns. The display panels are assembled and disassembled from their standards and with one another by telescoping slide joints.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
61 words
A display panel comprising a panel member having two oppositE upright parallel sides, and two column members attached thereto along said opposite sides, said column members each extending approximately from the same end and to approximately the midpoint of the respective sides of said panel member, said column members each having opposite ends formed to telescopingly receive portions of connecting parts.
Claim 2
Dependent Claim
61 words
A display panel comprising a panel member having two oppositE upright parallel sides, and two column members attached thereto along said opposite sides, said column members each extending approximately from the same end and to approximately the midpoint of the respective sides of said panel member, said column members each having opposite ends formed to telescopingly receive portions of connecting parts.
Claim 3
Dependent Claim
67 words
A display panel as defined in claim 1 further characterized by said panels having laterally projecting flanges extending therefrom along said opposite sides and said column members each comprising a tubular member open along one side and having oppositely facing groove formations along opposite sides of said opening with said flanges along the respective sides of said panel received therein to secure said members to said panel.
Claim 4
Dependent Claim
73 words
A display panel as defined in claim 1 further characterized by a tubular member, the major portion thereof having an outside diameter equal to that of one of said column members and having a shank portion at one end of said major portion of reduced diameter received in one end of said one column member, the length of said major portion of said tubular member being approximately one-half the length of said panel.
Claim 5
Dependent Claim
44 words
A display panel as defined in claim 3 further characterized by said column member having said one end terminating at the midpoint of one of said sides of said panel, said tubular member extending from said midpoint to the other end of said panel.
Claim 6
Dependent Claim
43 words
A display panel as defined in claim 4 further characterized by a tubular support leg having a major portion thereof of the same outside diameter as said members and having and end shank portion of reduced diameter telescoped into one of said members.
Claim 7
Dependent Claim
18 words
A display panel as defined in claim 5 further characterized by said one member comprising said column member.
Claim 8
Dependent Claim
18 words
A display panel as defined in claim 1 further characterized by said column members having a cylindrical form.
Claim 9
Dependent Claim
16 words
A display panel as defined in claim 5 characterized by said members being of cylindrical form.
Claim 10
Dependent Claim
97 words
A display panel structure comprising in combination, a plurality of rectangular panel members, each of said members having two tubular column members attached thereto at opposite sides and extending from the same end of the panel member and along approximately one-half the length of the respective opposite sides, a column member of one panel being axially aligned with a column member of an adjacent panel member and having ends thereof adjacent one another, and a connector member interconnecting said axially aligned adjacent ends of said column members and operative to maintain the last mentioned column members aligned.
Claim 11
Dependent Claim
97 words
A display panel structure comprising in combination, a plurality of rectangular panel members, each of said members having two tubular column members attached thereto at opposite sides and extending from the same end of the panel member and along approximately one-half the length of the respective opposite sides, a column member of one panel being axially aligned with a column member of an adjacent panel member and having ends thereof adjacent one another, and a connector member interconnecting said axially aligned adjacent ends of said column members and operative to maintain the last mentioned column members aligned.
