This invention relates to displays of the type used by exhibitors at trade
shows, exhibitions and conventions to advertise and promote their goods or
services.
BACKGROUND OF THE INVENTION
Collapsible displays have become increasingly popular with exhibitors due
to the fact that they may be readily assembled and disassembled, and can
be stored in shipping cases for transportation from one location to
another. In general, such displays comprise a series of components,
primarily in the form of panels, which when assembled form a display
booth. Such displays come in various sizes ranging from so-called tabletop
displays to floor supported displays which are of normal room height. By
having a series of interconnected panels, the displays may take different
shapes so as to accommodate the display to the space available or to the
particular needs of the exhibitors.
A popular type of display currently in use comprises a series of modular
panels formed from laminated sheet material, the panels being framed in
aluminum, usually in the form of channel-shaped members which engage the
edges of the panel forming sheet material. The panels are normally hinged
together using conventional metal hinges. Many exhibitors have, however,
objected to displays of this character in that the protective aluminum
framing along the abutting side edges of adjacent panels interrupts the
continuity of the display and its colorscheme by dividing the display into
a series of discrete and readily discernable panels. While various efforts
have hitherto been made to eliminate the metallic borders and conventional
hinges, as by utilizing fabric or plastic hinges, these expedients have
not been very successful due to the lack of stability of the hinge forming
materials which, in turn, decrease the stability of the entire display. In
many instances, the lack of firm support for the panels along the hinge
lines result in warping or bowing of the panels, and in addition the
resultant hinge lines are often unattractive and detract from the
appearance of the display.
In contrast to the foregoing, the present invention provides a unique
system of articulated display panels which effectively eliminates the
difficulties experienced with prior art panel systems and at the same time
provides an extremely attractive and versatile display.
SUMMARY OF THE INVENTION
In accordance with the present invention, a series of display panels is
formed from a single length of panel forming material comprising a
honeycomb core formed from kraft paper, the core being faced on both sides
with paperboard stock. For convenience in description, the basic panel
forming material will be described herein as honeycomb sheeting. Such
honeycomb sheeting is commercially available and is normally treated with
flame retardant chemicals and polymers to increase its fire resistance and
strength. In addition, the facing panels may have a thin layer of aluminum
foil laminated to their outer surfaces to further enhance the fire
resistance and strength of the honeycomb sheeting. While light in weight,
the sheeting is nonetheless rigid and not readily subject to warping or
bowing.
In accordance with the invention, a continuous length of honeycomb sheeting
of a size to form a series of articulated display panels is covered on
both sides with a continuous length of facing material, preferably a
fabric engagable by Velcro type fasteners, although other fabrics or
plastic materials may be used, the facing material being securely
laminated to the honeycomb sheeting by means of a suitable bonding
adhesive. Preferably, the opposite sides of the honeycomb sheeting will be
covered by a continuous length of facing material which bridges the edge
of the honeycomb sheeting defining the uppermost edges of the panels being
formed, thereby providing a finished upper edge.
Following the lamination of the facing material to the honeycomb sheeting,
the panel forming material is then subjected to a scoring operation in
which the panel forming material is scored from both sides to define a
series of articulated panels hinged together in side-by-side relation. The
panels are separated by spaced apart pairs of score lines which define
hinge forming bridges in the areas between the pairs of score lines. The
scoring of the panels is such that the honeycomb sheeting will be
flattened to near its center line from both sides in the areas of the
spaced apart score lines, and in addition the honeycomb sheeting will be
compressed and partially crushed in the areas defining the hinge forming
bridges, the bridge areas displaying a convex curvature on both sides of
the panels. Such curvature is both decorative and functional, the curved
bridge areas forming attractive yet unobtrusive hinges while at the same
time providing strength and rigidity in the areas of the hinges. Such
bridging areas readily lend themselves to folding in either direction and
provide smoothly rounded edges when adjacent panels are folded relative to
each other.
Following scoring, the top, bottom, and free side edges of the outermost
panels are bordered with channel-shaped strips, preferably aluminum, the
strips which extend along the top and bottom edges of the panels
terminating short of the hinge forming bridges so that the panels are free
to fold relative to each other. However, when it is desired to secure
adjacent panels in a particular fixed relation relative to each other,
channel-shaped locking elements are provided which clamp over and extend
between the frame forming channels extending along the top edges of
adjacent panels, the locking elements serving to effectively lock the
adjoining panels together in their desired position of use. Where a series
of adjoining panels is to extend in a straight line relative to each
other, the locking elements comprise straight lengths of channel-shaped
material; whereas if an adjoining pair of panels is to be angularly
disposed relative to each other, the locking element is composed of a pair
of channel-shaped locking members interconnected by a metal strap bent to
the desired angle. To this end, the metal strap is preferably formed from
an essentially dead-soft metal which may be repeatedly bent as desired and
which, when bent to a particular angle, will retain that configuration
until bent to a different angle. Consequently, the exhibitor may readily
lock the panels in any desired position of use utilizing a minimal number
of different locking members.
Accordingly, a principal object of the present invention is the provision
of a display composed of a plurality of articulated panels provided with
integral hinge forming bridges which are both decorative and functional.
A further object of the invention is the provision of an articulated panel
display in which the hinges do not interfere with the continuity of the
display, such as its color scheme, and at the same time the configuration
of the hinge forming bridge areas provides an attractive adjunct to the
panels together with strength and rigidity.
Still a further object of the invention is the provision of a panel display
system incorporating locking elements which enable the exhibitor to secure
the panels together in any desired positions of use, the securing elements
themselves being unobtrusive and blending in to the channels which border
the marginal edges of the system. The foregoing, together with other
objects of the invention which will appear hereinafter or which will be
apparent to the worker in the art upon reading this specification are
accomplished by those constructions and arrangements of parts which will
now be described in detail.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to FIG. 1 of the drawings, an articulated panel display is
indicated generally at 1, the display in this instance comprising a series
of panels 2, 3, 4, 5, 6 and 7 hingedly connected together along their
adjoining side edges by means of integral hinge forming bridges 8.While in
the display illustrated there are six articulated panels, the number of
panels may be varied as desired, as may the height and width of the
panels, depending upon whether the display is for tabletop or floor usage.
It is also within the spirit of the invention to provide upper and lower
sections adapted to be connected together by fastener means of known
character, thereby permitting storage and shipment of the panels in
convenient length for handling. The top and bottom edges of the panels are
provided with borders 9 and 10, respectively, preferably in the form of
channel-shaped aluminum edging, which serves both to mask and protect the
edges of the panels as well as strengthen the exposed edges. The free side
edges of the outermost panels 2 and 7 are also provided with
channel-shaped borders 11 and 12, respectively, which protect and
reinforce the exposed side edges of the panel display. While aluminum
channels are preferred, the channel-shaped borders may be formed from
other materials, such as extruded plastic. It will be understood, of
course, that the border forming channels will be of a size to snuggly fit
over the edges of the sheeting, and they are preferably secured in place
by means of adhesive, although rivet-like fasteners or other fastening
means may be employed, if desired. It is also preferred to provide feet
10a along the bottom edges of the panels, the feet being in the form of
rubber or plastic buttons secured to the undersurfaces of the
channel-shaped edge forming members 10.
As illustrated in FIG. 1, the panels are in erected condition in which they
form a display, the outermost panels 2 and 7 being inclined with respect
to the adjoining panels 3 and 6, respectively, whereas the panels 3, 4, 5
and 6 are arranged in a straight line. This arrangement is exemplary only
since the panels may be arranged in any desired angular relationship with
respect to each other, or they may be arranged in semicircular or even
circular fashion, depending upon the desired configuration of the display.
It will be understood that the display may include additional components,
such as headers, lighting fixtures, copy signs, shelving and the like,
which as such do not form a part of the present invention. For shipping
and storage purposes, the panels may be folded relative to each other to
form a flat-folded compact unit, the folded condition of the display being
illustrated in FIG. 2.
In accordance with the invention, the panel display is formed from a
continuous length of panel forming material of the desired size; that is,
the panels 2, 3, 4, 5, 6, and 7 initially comprise a unitary sheet of
laminated stock which is scored to define the various panels and their
interconnecting bridge forming hinges as an incident of the fabrication of
the panel display. The base material from which the panel display is
fabricated comprises honeycomb sheeting composed of a honeycomb core,
indicated at 13 in FIG. 3, which is faced on both sides with facing
sheets, one of which is indicated at 14, the facing sheets being formed
from paperboard or boxboard with the end edges of the honeycomb cells
bonded to the inner surfaces of the facing sheets. While the thickness of
the honeycomb sheeting does not constitute a limitation on the invention,
thicknesses of approximately 3/8 to 1/2 inch have been found particularly
suited for display panel use. Preferably the honeycomb core and the facing
sheets will be chemically treated to render them fire retardant, and
polymers also may be used to enhance the strength of the honeycomb
sheeting. In addition, it is preferred to use honeycomb sheeting having a
thin layer of aluminum foil, indicated at 15 in FIG. 3, laminated to the
outer surfaces of the facing sheets 14, the foil serving to enhance the
fire retarding properties of the sheeting as well as provide a moisture
barrier.
The honeycomb sheeting is covered on both sides with a facing material 16,
preferably a fabric capable of being engaged by a Velcro type fastener,
having a multiplicity of tiny fabric engaging hooks, thereby facilitating
the attachment of display materials, lighting fixtures and the like
equipped with Velcro type fasteners. Other types of fabrics and plastic
facing materials may be utilized, depending upon the desired surface
finish for the panels. Interesting decorative effects can be achieved by
combining fabrics of different colors and/or textures. It is preferred,
however, that the fabric bridges at least the edge of the honeycomb
sheeting which defines the upper edges of the panel display being formed.
If, for example, a single color fabric is to be utilized, it is preferred
that the fabric be of a size such that a continuous length of the fabric
will cover both sides of the honeycomb sheeting. In instances where
different fabrics are utilized, it is preferred that the fabrics are
arranged so that a continuous length of fabric will bridge the edge of the
honeycomb sheeting which forms the uppermost edges of the panels, thereby
providing a neatly finished edge in the areas of the bridge forming hinges
8. If desired, both the upper and lower edges of the panels may be bridged
by the fabric, or the edges of the material may be tucked into the edges
of the honeycomb sheeting to form finished edges. The facing material
preferably will be adhesively secured to the facing sheets 14 by the use
of any suitable adhesive material. While a water base adhesive is
preferred, either heat activated or pressure sensitive adhesive may be
used.
Following lamination of the facing material to the honeycomb sheeting, the
material is next subjected to a scoring operation to define the hinge
forming bridges 8, the scoring being carried out by sets of scoring rules
positioned to contact the opposite sides of the laminated sheeting. The
scoring rules are configured to define spaced apart sets of mating score
lines 17, 17a and 18, 18a which define the adjacent side edges of an
adjoining pair of panels, such as the panels 6 and 7 seen in FIG. 4, the
area lying between the score lines 17, 17a and 18, 18a defining the hinge
forming bridges, the opposite sides of which are designated 8a and 8b.
Preferably the width of the bridge areas 8a and 8b will be greater than
the thickness of the surfaced honeycomb sheeting but not substantially
greater than twice the thickness thereof, the objective being to have the
hinge forming bridges form neatly rounded edges when the panels are
folded. As will be apparent from FIG. 4, the sheeting is crushed and
flattened in the areas of the mating score lines to near the center line
of the honeycomb sheeting. The bridge forming areas 8a and 8b lying
between the pairs of score lines 17, 18 and 17a, 18a are not completely
flattened; rather, the sheeting is only partially crushed, the scoring
rules being configured to provide a convex or rounded curvature to the
bridge areas 8a and 8b when viewed in cross-section. By reason of this
configuration, the hinge forming bridges are reinforced and strengthened
and yet the adjoining panels are free to fold in either direction. When
adjoining panels are folded relative to each other, as illustrated in FIG.
5, the score lines 17 and 18 on the outside of the fold tend to flatten
and disappear, the curved portion 8b defining an essentially smooth
rounded edge. On the inside of the fold, the panels 6 and 7 effectively
pivot about their respective score lines 17a and 18a, and the curved
portion 8a retains its bead-like configuration. Thus, due to the internal
reinforcement of the hinge forming bridges provided by the honeycomb
sheeting, the hinge areas maintain their integrity and their strength and
rigidity contribute to the overall stability of the display.
While the panels making up the display may be arranged in any desired
angular configuration with respect to each other, once the display has
been erected it is desirable to secure the panels against accidental
displacement. To this end, the panel display system of the present
invention utilizes locking elements which may be readily attached to the
uppermost edges of the panels, the locking elements being in the form of
channel-shaped members of a size to snuggly fit over the channel members
forming a border for the uppermost edges of the panels. By making the
locking elements correspond in depth to the border forming channels and of
the same material or color, they blend into the borders and are barely
discernable.
Where adjoining channels are to be joined together in a straight line, the
locking element may comprise a straight length of channel-shaped aluminum
or the like, as indicated at 19 in FIG. 6, the locking element being of a
length to span the hinge forming bridge 8, with its opposite end edges
engaging about the end edges of the border channels 9. When the locking
element 19 is in place, it will be evident that the panels 6 and 7 cannot
be folded relative to each other and hence will retain their straight line
relationship.
Where adjoining panels are angularly disposed with respect to each other,
the locking element 20 illustrated in FIGS. 7 and 8 is used. This element
has a pair of channel-shaped members 21 and 22 each of a size to clamp
against the border forming channel members 9. The two members are
interconnected by a metallic strap 23 having its opposite ends secured to
the members 21 and 22, as by means of rivets 24. By bending the strap 23,
the channels 21 and 22 may be disposed at any desired angle with respect
to each other, and when the locking element is clamped to the upper edges
of an adjoining pair of panels, the panels will be secured at the angle
established by the locking element. Preferably the strap 23 will be formed
from an essentially dead-soft metal so that the locking elements may be
readily bent by the exhibitor to any desired angle, thereby enabling the
exhibitor to lock the panels in any selected configuration. Of course, the
straps 23 may be permanently set in a given bent condition so as to
establish a fixed angle between the channel members 21 and 22.
As should now be apparent, the present invention provides an improved
articulated panel display having integral hinges which are both functional
and decorative, the panel system including locking elements by means of
which the panels may be secured in any desired positions of use relative
to each other. It will be understood that modifications may be made in the
invention without departing from its spirit and purpose, the invention
being limited only in the manner set forth in the claims which follow.
