DISPLAY EXHIBIT MODULE
Abstract
A display exhibit module is assembled from a series of inner
sleeves and rectangular outer sleeves constructed out of
paperboard. Each inner sleeve has a stepped construction such that
the rectangular cross section of its lower portion is larger than
the rectangular cross section of its upper portion. The lower
portion of the inner sleeve is fitted snugly within an outer sleeve
with part of its upper portion extending above the outer sleeve.
The height of the exhibit module can be extended upward by placing
a second outer sleeve snugly over the extended portion of the inner
sleeve so that when it rests on the first outer sleeve, a portion
of the second outer sleeve will extend above the inner sleeve. The
display exhibit module can be further increased in height by adding
additional inner sleeves and outer sleeves.

Description
BACKGROUND OF THE INVENTION
This invention relates to exhibit modules constructed out of
paperboard, preferably fireproof, used to construct a display for
an exhibit area.
Exhibitors are continually faced with the problem of suitably
laying out and decorating exhibit areas. Usually, exhibit areas are
delineated by booths or stands usually constructed out of wood or
other relatively heavy materials. The booths may be provided but
quite often are specially constructed for each exhibit. To minimize
construction costs, the booth for an area often is constructed as a
single unit, or, if modular construction is employed, rather large
modules are utilized. This results in cumbersome exhibits which are
not easily modified should an unforeseen layout problem be
encountered. Other disadvantages of many booths or stands presently
in use are the high cost of shipping both the raw materials to make
the booths and the finished booths themselves and the high cost of
assembling, decorating and, finally, disassembling the booths after
the exhibition.
It can be seen that there is a need for a module which can be used
to build up a display exhibit. Each module should be light of
weight to facilitate handling before and after assembly. A small
number of standard modules could be designed to standardize the
manufacture of the modules. This modular approach also provides
increased flexibility in the shape of the completed display. It
would also be desirable for each module, in turn, to be
disassembled to facilitate handling during shipping and storage. It
would also be desirable that the overall volume of each module in
the disassembled state be considerably less than its volume in the
assembled state which will tend to reduce shipping and storage
costs.
It is an object of this invention to provide a lightweight exhibit
module suitable for constructing a display for an exhibit area.
Another object of this invention is to provide an exhibit module
which can be easily assembled and disassembled.
Another object of this invention is to provide a lightweight
exhibit module which can be easily moved in order to accommodate
sudden changes in the layout of an exhibit area.
It is another object of this invention to provide a reusable
exhibit module.
And yet another object of this invention is to provide an exhibit
module which, when disassembled, each assembly can be folded flat,
thereby minimizing the volume during shipping and storage.
SUMMARY OF THE INVENTION
In accordance with this invention, an exhibit module is assembled
from a series of inner sleeves and rectangular outer sleeves
constructed out of paperboard-like material preferably fireproof.
In one embodiment, an inner sleeve has a stepped construction such
that the rectangular cross section of its lower portion is larger
than the rectangular cross section of its upper portion. The lower
portion of the inner sleeve is fitted snugly within an outer
sleeve, thereby lending structural rigidity to the combined
assembly. Part of the upper portion of the inner sleeve extends
above the outer sleeve. The height of the exhibit module can be
extended upward by placing a second outer sleeve snugly over the
extended portion of the inner sleeve so that when it rests on the
first outer sleeve, a portion of the second outer sleeve will
extend above the inner sleeve. The display exhibit module can be
further increased in height by adding additional inner sleeves and
outer sleeves.

DETAILED DESCRIPTION
FIG. 1 shows the assembled display exhibit module 10 of this
invention. The display exhibit module 10 is comprised of a series
of rectangular outer sleeves, hereinafter referred to as the lower
outer sleeve 11, middle outer sleeve 12 and upper outer sleeve 13,
and a series of stepped inner sleeves, hereinafter referred to as
the lower inner sleeve 14 and the upper inner sleeve 15. In a
preferred embodiment of the invention, lighting fixtures 16 and 17
are supported within the display exhibit module 10 to illuminate
the front walls 18 and 19 of the display exhibit module 10. Power
is distributed to the lighting fixtures 16 and 17 by means of plug
21 and line cord 22 which extends through power cord hole 23 in the
sidewall of the display exhibit module 10. Since usually a
plurality of display exhibit modules will be grouped to form a
display, an extension cord 24 and extension socket 25 extend
through a power cord hole, not shown, in another wall of the
display exhibit module so that power can be supplied to the
lighting fixtures in an adjacent display exhibit module.
FIG. 2 shows how the assembled sleeves of FIG. 1 fit together to
make a display exhibit module. For the sake of convenience,
elements described with reference to a specific figure will retain
the same reference designation in the description of subsequent
figures. Referring now to FIG. 2, the lower outer sleeve 11 is a
box structure having two sidewalls 30 and 31, a front wall 32, a
rear wall 33 and a bottom 34. There is a power cord hole 23 near
the bottom of sidewall 30 to allow the passage of a line cord and
plug for lighting equipment which can be mounted within the
assembled exhibit module. Sidewall 31 and rear wall 33 may also
have such holes.
The lower inner sleeve 14 has two sidewalls 36 and 37, a rear wall
38, a lower front wall 39 and an upper front wall 40. The sidewalls
36 and 37 are stepped at edges 41 and 42 so that the rectangular
cross-section of the lower inner sleeve 14 formed by the sidewalls
36 and 37, the rear wall 38 and the lower front wall 39 is larger
than the rectangular cross-section formed by the sidewalls 36 and
37, the rear wall 38 and the upper front wall 40. There is a hole
(not shown) in the sidewall 36 so positioned that it will line up
with the hole 23 in the sidewall 30 of the lower outer sleeve 11
when the lower inner sleeve 14 is inserted within the lower outer
sleeve 11. Similar holes may exist in the rear wall 38 and the
sidewall 37 which will line up with corresponding holes in the rear
wall 33 and the sidewall 31 of the lower outer sleeve 11. Notches
43 and 44 are cut out of sidewalls 36 and 37 respectively to
facilitate the mounting and recessing of a lighting fixture within
the lower inner sleeve 14 as illustrated in FIG. 3. The lower inner
sleeve 14 is so dimensioned that its lower portion fits snugly
within the lower outer sleeve 11, thereby lending rigidity to the
combined structure. The height of the lower front wall 39 of the
lower inner sleeve 14 is such that the step edges 41 and 42 of
sidewalls 36 and 37 are at or just below the top edges of sidewalls
30 and 31 of lower outer sleeve 11 when the lower inner sleeve 14
is completely inserted within the lower outer sleeve 11. Thus, all
or substantially all of the upper portion of the lower inner sleeve
18 having the smaller cross section extends above the lower outer
sleeve 11.
The middle outer sleeve 12 is rectangular in shape and has two
sidewalls 47 and 48, a front wall 18 and a rear wall 50 and is
dimensioned to fit snugly over the upper part of the lower inner
sleeve 14. The upper portion of the lower inner sleeve 14 lends
structural rigidity to the middle outer sleeve 12 when they are
assembled to form an exhibit module.
The upper inner sleeve 15 is similar in construction to the lower
inner sleeve 14. The upper inner sleeve 15 has two stepped
sidewalls 51 and 52, a rear wall 53, a lower front wall 54 and an
upper front wall 55. The cross-sectional area of the upper inner
sleeve 15 as formed by stepped sidewalls 51 and 52, rear wall 53,
and lower front wall 54 is larger than the cross-sectional area as
formed by sidewalls 51 and 52, rear wall 53 and upper front wall
55. Notches 56 and 57 have been cut into the step edges 58 and 59
of the sidewalls 51 and 52 to facilitate the mounting and recessing
of lighting fixtures within the upper inner sleeve 15. The upper
inner sleeve 15 is dimensioned so that its lower portion fits
snugly within the middle outer sleeve 12, thereby lending rigidity
to the resulting structure. The sidewalls 51 and 52 are so
dimensioned that when the exhibit module is assembled, stepped
edges 58 and 59 will lie at or slightly below the top of the
sidewalls 47 and 48 of the middle outer sleeve 12 and all or most
of the upper portion of the inner sleeve 15 will extend above the
middle outer sleeve 12.
The upper outer sleeve 13 has two sidewalls 61 and 62, a rear all
63, a front wall 19, and a top 65 and is so dimensioned to fit
snugly over the upper portion of the upper inner sleeve 15. The
upper portion of the upper inner sleeve 15 lends rigidity to the
upper outer sleeve 13 when they are assembled to form an exhibit
module.
An exhibit module is assembled by inserting the lower inner sleeve
14 within the lower outer sleeve 11 with the lower edges of
sidewalls 36 and 37, rear wall 38 and lower front wall 39 resting
on the bottom 34 of the lower outer sleeve 11. The upper portion of
the lower inner sleeve 14 will extend above the lower outer sleeve
11. The middle outer sleeve 12 is placed over the extended upper
portion of the lower inner sleeve 14 with the bottom edges of
sidewalls 47 and 48 and rear wall 50 resting on corresponding top
edges of the sidewalls 30 and 31 and rear wall 33 of the lower
outer sleeve 11.
A slot 66 has been cut out of the top edge of sidewalls 30 and 31
of lower outer sleeve 11. Both sidewalls 47 and 48 of the middle
outer sleeve 12 terminate in a tab 67 positioned so as to engage
slot 66. The tabs have been formed with recesses 68a and 68b thus
forming tab ledges 69a and 69b. The dimension, a, of the tab 67 is
slightly greater than the length, b, of the slot 66. During the
assembly of the middle outer sleeve 12 on the lower outer sleeve
11, tab 67 is forced into slot 66.
Although the tab 67 and the slot 66 undergo a slight deformation
when the tab 67 is forced into the slot 66, the tab 67 and the slot
66 will recover sufficiently so that tab ledges 69a and 69b will
engage the underside of the edge of sidewall 30, thereby increasing
the stability of the assembled parts.
Part of the middle outer sleeve 12 extends above the upper portion
of the lower inner sleeve 14. The upper inner sleeve 15 is now
placed within the extended portion of the middle outer sleeve 12
with the bottom edges of sidewalls 51 and 52, rear wall 53 and
lower front wall 54 resting on the corresponding top edges of
sidewalls 36 and 37, rear wall 38 and upper front wall 40 of the
lower inner sleeve 14. The upper portion of the upper inner sleeve
15 extends above the middle outer sleeve 12. The upper outer sleeve
13 is fitted over the upper portion of the upper inner sleeve 15
with the lower edges of sidewalls 47 and 48 and rear wall 53 of the
middle outer sleeve 12. Tabs 71 protrude from sidewalls 61 and 62
and engage slots 70 in the edge of sidewalls 47 and 48 to lend
stability to the assembled parts. A portion of the upper outer
sleeve 13 extends above the upper portion of the upper inner sleeve
15.
It will be obvious to one skilled in the art that the height of the
exhibit module can be further extended by adding additional inner
sleeves and outer sleeves. It will also be apparent that extensions
can be accomplished with nonstepped inner sleeves or with stepped
inner sleeves in which the lower portion has a smaller
cross-section than the upper portion.
FIG. 3 shows how lighting fixtures 16 and 17 can be mounted in the
stepped inner sleeve to illuminate the front surfaces of an
assembled exhibit module. In FIG. 3, only those portions of the
inner sleeves necessary to illustrate the mounting of the lighting
fixtures has been show. Lighting fixtures 16 and 17 each contain
two fluorescent lamps 73a and 73b, and 74a and 74b. Attached to
each end of lighting fixtures 16 and 17 is a mounting bracket 75a
and 75b, and 76a and 76b.
As illustrated in FIG. 1, lighting fixture 16 is assembled into
lower inner sleeve 15. As shown in FIG. 3, the mounting brackets
75a and 75 are supported in the notches 43 and 44 of sidewalls 36
and 37, the notches so acting to retain the lighting fixture within
the lower inner sleeve, thereby concealing the fluorescent lamps
73a and 73b. In a similar manner, lighting fixture 17 is mounted in
the upper inner sleeve 15 with the mounting brackets 76a and 76b
resting in notches 56 and 57 of sidewalls 51 and 52.
Lighting fixture 16 has a main line cord 22 terminated in plug 21
which can be plugged into a source of power. Lighting fixture 16
has an auxiliary line cord 77 terminated in plug 78 for
transferring power to lighting fixture 17, and an extension line
cord 24 terminated in plug 25 for transferring power to lighting
fixtures in an adjacent exhibit module. Lighting fixture 17 has
only a single line cord 79 terminated in plug 80 for obtaining
power from lighting fixture 16 when plug 78 is plugged into plug
80.
As shown more particularly in FIGS. 4 and 5, a lower outer sleeve
is made from two rectangular sheets of paperboard appropriately
cut, scored and fastened together as described herein. As shown in
FIG. 4, the rectangular blank from which the sidewalls and front
wall are formed is originally defined by edges 82, 83, 84 and 85.
Sections 86 through 92, slots 66 and 66a, and holes 23 and 23a are
cut out of the blank. The blank is scored along lines 94 through
100 to facilitate the folding of the paperboard along those lines.
The score lines divide the cut blank into the following areas: glue
flaps 101 and 102, sidewalls 30 and 31, front wall 32, bottom flaps
34a, 34b and 34c, top flaps 103, 104 and 105, and top edges 106a,
106b, 107, 108a and 108b.
As shown in FIG. 5, the blank from which the rear wall 33 is formed
is originally defined by edges 110, 111, 112 and 113. Sections 114,
115, 166 and 117 as well as holes 118 and 119 are cut out of the
blank. The blank is then scored along lines 120, 121 and 122,
thereby dividing the blank into the following areas: bottom flap
34d, rear wall 33, top edge 123 and top flap 124.
To assemble the lower outer sleeve, sidewalls 30 and 31 are folded
along score lines 98 and 99 respectively, so that they are parallel
opposed and perpendicular to the front wall 32. Glue flaps 101 and
102 are then folded in toward the enclosure along score lines 97
and 100 so that they lie in a plane parallel to forward wall 32.
Glue glaps 101 and 102 are fastened to rear wall 33 so that edge
111 of rear wall 33 coincides with the edge of sidewall 31 formed
by score line 97, and edge 113 of rear wall 33 coincides with the
edge of sidewall 30 formed by score line 100.
The assembly of the bottom 34 of the lower outer sleeve as
illustrated in FIG. 6 is accomplished by bending bottom flap 34b
into the enclosure along the score line 96 so that it is
perpendicular to the forward wall 32 as shown in FIG. 6. Bottom
flaps 34a and 34c are then folded in toward the enclosure along
score line 96 until they are perpendicular to sidewalls 31 and 30
and partially resting on bottom flap 34. Bottom flap 34d is then
folded in toward the enclosure along score line 122. When bottom
flap 34d is perpendicular to the rear wall 33, edge 112 will be
resting on bottom flap 34b. Pressure is continued on bottom flap
34d which pushes bottom flaps 34a, 34b and 34c in toward the
enclosure until edge 112 of bottom flap 34d slips below edge 125 of
bottom flap 34b whereupon the pressure on bottom flap 34b is
suddenly decreased causing it to spring back toward the
perpendicular to rear wall 33. When pressure is now removed from
bottom flap 34d, edge 112 thereof will be underneath bottom flap
34b thereby forming an interlocked bottom. The top 65 of the upper
sleeve 13, as is illustrated in FIG. 2, is assembled in a similar
manner.
Referring now to FIGS. 4 and 5, to complete assembly of the lower
outer sleeve, top flap 103 is folded inside the enclosure about
score lines 94 and 95 so that the top edge formed by surfaces 106a
and 106b is perpendicular to sidewall 31, and top flap 103 is
parallel to sidewall 31. In a similar manner, top flap 105 is
folded inside the enclosure about score lines 94 and 95. Top flap
104 is then folded into the enclosure about score lines 94 and 95
so that top edge 107 is perpendicular to front wall 32, and top
flap 104 is parallel to front wall 32. Similarly, top flap 124 is
folded inside the enclosure about score lines 120 and 121 so that
top edge 123 is perpendicular to rear wall 33, and top flap 124 is
parallel to rear wall 33.
The edges of top flaps 103, 104, 105 and 124 have been designed so
that they will lock in place in the assembled position to prevent
the flaps from returning to the disassembled position nd to
increase the rigidity of the assembled exhibit module. The
interlocking feature is more particularly illustrated in FIG. 7. In
FIG. 7, top flap 105 is shown in the assembled position. Each end
of the top flap has a protrusive tab 127 and a recessed edge 128.
Each side of top flap 124, shown in the disassembled position, also
terminates in a protrusive tab 129 and a recessed edge 130. When
top flap 124 is folded into the assembled position, recessed edge
128 of top flap 105 cooperates with protrusive tab 129 to prevent
top flap 124 from returning to the disassembled position. In a
similar manner, recessed edge 130 of top flap 124 cooperates with
protrusive tab 127 of top flap 105 to prevent its return to the
disassembled position. A similar interlocking feature exists in
each corner of the assembly.
As shown in FIGS. 8 and 9, the lower inner sleeve 14 is made from
two rectangular sheets of paperboard appropriately cut, scored,
folded and fastened together as described herein. As shown in FIG.
8, the rectangular blank from which the sidewalls 36 and 37, the
upper front wall 40 and the lower front wall 39 are formed is
originally defined by edges 132 through 135. Section 136, notch 44
and holes 23b and 23c are cut out of the blank. The blank is then
cut along line 137. The blank is scored along lines 138 through
141, thereby dividing the blank into the following areas: sidewall
36, lower front wall 39, sidewall 37, upper front wall 40 and glue
flap 142.
As shown in FIG. 9, the rear wall 38 of the lower inner sleeve 14
is formed from a rectangular blank, only part of which is
illustrated, originally defined by edges 143 through 146. Each
corner of the blank is trimmed by removing the sections, such as
sections 147, 148 and 149, and holes 118a and 119a are also removed
from the blank. The blank is scored along lines 150 and 151,
thereby dividing the blank into a rear wall 38 and glue flaps 152
and 153.
In order to assemble the lower inner sleeve as shown more
particularly in FIG. 10, sidewalls 36 and 37 are folded along score
lines 141 and 139 respectively until they are parallel opposed and
perpendicular to lower front wall 39. Glue flaps 152 and 153 are
folded along score lines 149 and 150 until they are parallel
opposed and perpendicular to rear wall 38. Glue flaps 152 and 153
are fastened to sidewalls 36 and 37 respectively so that edge 133
of sidewall 36 coincides with score line 149 of rear wall 38, and
edge 135 of sidewall 37 coincides with score line 150 of rear wall
38. The assembly is completed by folding the upper front wall 40
into the enclosure at score line 138 so that it is perpendicular to
sidewall 37 and folding glue flap 142 into the enclosure about
score line 140 so that it is perpendicular to upper front wall 40.
The glue flap 142 is fastened to sidewall 36 so that edge 154 of
sidewall 36 coincides with the edge of upper front wall 40 formed
at score line 140.
FIG. 11 shows in detail how a typical upper outer sleeve is made
from a single paperboard blank, only part of which is illustrated.
The rectangular blank is originally defined by edges 156 through
159. Sections 160 through 169, as well as slots 70 and 70a are cut
out of the blank. Tab outlines 170 and 171 are cut to form tabs 67
and 67a. The blank is scored along lines 172 through 179, thereby
dividing the blank into the following areas: glue flap 180,
sidewall 47, rear wall 50, sidewall 48, front wall 18, top flaps
181 through 184, top edges 185a through 185f, bottom flaps 186
through 189, bottom edges 190a through 190f, and tabs 67 and
67a.
The assembly of a typical outer sleeve is accomplished by folding
the blank about score lines 177 and 178 so that front wall 18 and
rear wall 50 are parallel opposed and perpendicular to sidewall 47.
Sidewall 48 is folded into the enclosure about score line 179 until
it is parallel opposed to sidewall 47 and perpendicular to rear
wall 50. Glue tab 180 is folded into the enclosure about score line
176 until it is perpendicular to front wall 18. Glue tab 180 is
then astened to sidewall 48 so that edge 157 of sidewall 48
coincides with the edge of front wall 18 formed at score line 176.
Top flaps 182 and 184 are then folded into the enclosure about
score lines 172 and 173 so that they are parallel to sidewalls 47
and 48. Top flaps 181 and 183 are folded into the enclosure about
score lines 172 and 173 and interlocked with top flaps 182 and 184
as previously discussed and illustrated in FIG. 7. Similarly,
bottom flaps 186 and 188 are folded into the enclosure about score
lines 174 and 175 leaving tabs 67 and 67a in the same plane as
sidewalls 47 and 48 respectively. The assembly of the typical outer
sleeve is completed by folding bottom flaps 185 and 187 into the
enclosure so as to interlock with bottom flaps 186 and 188.
The description heretofore has been of a single display exhibit
module about 8 feet tall and about 2 1/2 feet wide. It is readily
apparent that a plurality of such display exhibit modules can be
used to construct a display for an exhibit area. Because of their
light weight, the exhibitor has added flexibility to adapt to
unexpected changes in the exhibit area.
The surfaces of the display exhibit module are particularly suited
to be decorated with posters or advertisements. The surfaces can be
predecorated, leaving only the assembly of the exhibit module for
the exhibit site. The step in each inner sleeve can be especially
adapted to receive a light fixture for illuminating the surface of
the assembled exhibit module, thereby enhancing the decorative
appearance of the exhibit module.
Each sleeve assembly can be folded into a flat configuration,
thereby reducing the volume for shipping, handling and storage and
encouraging reuse of the exhibit module. Another advantage of this
exhibit module is the ease of assembling and disassembling an
exhibit module.
While the present invention has been described with reference to a
specific embodiment thereof, it will be obvious to those skilled in
the art that various changes and modifications may be made without
departing from the invention in its broader aspects. For example,
the lower inner and outer sleeves can be constructed from a single
rectangular sheet of paperboard rather than from two sheets.
Similarly, the glue flaps can be fastened to the appropriate walls
of the sleeves by means of glue, staples or other fastening means
as is well known in the art. It is also obvious that the lower
outer sleeve can have tab assemblies while the upper outer sleeve
has the mating slot. It is contemplated in the appended claims to
cover all variations and modifications of the invention which come
within the true spirit and scope of my invention.
