Abstract
Abstract The portable exhibit system includes a plurality of display modules each of which has a pair of identical mirror image side support extrusions having a plain display panel or an illuminated display panel detachably connected therebetween. Up to three modules may be vertically interconnected at oblique angles relative to each other to define a display unit having a substantially concave continuous display surface with the bottom module having a pair of horizontal extruded support arms identical to said side support extrusions extending rearwardly therefrom. An illuminated header module may be detachably connected to the top end of the upper module. A plurality of display units each of which is comprised of a plurality of modules may be interconnected in side-by-side or back-to-back relation to provide an expanded exhibit system.

Claim 5
Dependent Claim
48 words
A portable exhibit system as set forth in claim 3, further comprising an illuminated header module having means adapatedto detachably secure said header module to the upper ends of the side support extrusions of said third module in overlying relation to said display means of said third module.
Claim 6
Dependent Claim
25 words
A portable exhibit system as set forth in any one of claims 1-3, wherein said display means is comprised of a rectilinear flat display panel.
Claim 7
Dependent Claim
31 words
A portable exhibit system as set forth in claim 5, wherein said flat panel is comprised of a sheet of fire retardent polyurethane foam sandwiched between two thin skins of fiberglass.
Claim 8
Dependent Claim
45 words
A portable exhibit system as set forth in any one of claims 1-3, wherein said display means is comprised of a rectilinear support panel having lighting means thereon, a flat rectilinear translucent panel and means for detachably connecting said translucent panel to said support panel.
Claim 9
Dependent Claim
106 words
A portable exhibit system as set forth in any one of claims 1-3, wherein each of said support extrusions is comprised of an elongated relatively flat strip having a plurality of parallel projections extending the entire length thereof defining a plurality of parallel slots, first flange means extending the length of said strip at opposite sides of said strip to define an oppositely opening channel at each side of said strip and second flange means extending from said first flange means in parallel overlying spaced relation to said strip to define a pair of opposed recesses on the opposite side of said strip from said protrusions.
Claim 10
Dependent Claim
48 words
A portable exhibit system as set forth in claim 8, wherein said display means is comprised of a rectilinear flat panel having a thickness sufficient to provide a close frictional fit of the edges of said panel in a pair of opposed slots on said side support extrusions.
Claim 11
Dependent Claim
34 words
A portable exhibit system as set forth in claim 9, wherein said side support extrusions are provided with three pairs of equally spaced apart slots in which said display panels may be selectively placed.
Claim 12
Dependent Claim
81 words
A portable exhibit system as set forth in claim 4, wherein said illuminated header module is comprised of a support panel having light means thereon, a pair of header support extrusions detachably connected to said support panel at opposite sides thereof, a lens member connected to said header support extrusions at opposite sides thereof and a header interlock molding extending along and secured to the lower edge of said lens and detachably secured to the lower edge of said support panel.
Claim 13
Dependent Claim
100 words
A portable exhibit system as set forth in claim 11, wherein each of said side support extrusions is provided with a pair of oppositely opening C-shaped channels extending along opposite longitudinal edges thereof and said header support extrusions are provided with flange means complimentary to said Cshaped channels for slidable reception therein to receive and support said illuminated header module between the side support extrusions of a module which includes a flat display panel, said illuminated header module further having stop means for limiting the sliding movement of said illuminated header module in said C-shaped channels of a display module.
Claim 14
Dependent Claim
35 words
A portable exhibit system as set forth in claim 12, further comprising cover means detachably connectable to said C-shaped channel means to cover the opening to said C-shaped channel means in said side support extrusion.
Claim 15
Dependent Claim
34 words
