[0001] THIS INVENTION relates to a display system suitable for temporary exhibition displays,
for example and which comprises a plurality of panels which are readily connectable
and disconnectable for assembly and disassembly of the display, the panels being interconnectable
at choice to form any desired one of a variety of display structures.
[0002] Such display systems are known, per se, and typically comprise a plurality of upright
poles supported by respective bases and rectangular panels which extend from pole
to pole and are clipped or otherwise attached to the respective poles at their respective
edges. Such known display systems suffer from various disadvantages, ranging from
low structural integrity to excessive complexity. Furthermore, some such known systems
are aesthetically unsatisfactory, for example in having intervening poles, connectors,
etc. exposed to view, distracting attention from the advertising or informational
material which the display is intended to exhibit. In addition such known systems
generally suffer from a lack of standardisation in dimensions between components,
in some cases inherent in the nature of the components, so that the construction of
any but the simplest display structures may require a large number of basically similar
but dimensionally slightly different components. It is an object of the invention
to provide an improved display system by which the above disadvantages may be avoided
or mitigated.
[0003] According to the invention, there is provided a display system comprising a plurality
of panels interconnected along adjoining sides by interengaging hinge formations comprising
respective hinge knuckle or bearing units carried by the respective panels on the
respective sides thereof and removable hinge pins extended through cooperating knuckle
or bearing units of the adjoining panels to establish connections between the same.
Preferably, said panels form part of a modular system wherein the dimensions of each
panel, as measured between the axes of respective hinge formations, are equal to a
predetermined standard dimension or to an integral multiple thereof.
[0004] An embodiment of the invention is described below by way of example with reference

[0005] Referring to the drawings, a display system embodying the invention comprises a plurality
of panels having predetermined modular dimensions, (as shown in Figure 7) interconnected
in such a way as to ensure that the resultant composite structure is also modular
- i.e. has dimensions which are a simple integral multiple of the basic modular dimension
or dimensions. The modular nature of the system is of significance in minimising manufacturing
costs and in maximising efficient use of spaces allocated at exhibitions, for example,
for such spaces are nowadays often allocated on a modular basis - i.e. the area allocated
for each display has its length and breadth determined according to simple multiples
of predetermined modular dimensions.
[0006] In accordance with the principle of maintaining modularity, the system is so arranged
as to ensure that interconnections between adjoining panels are made along lines of
interconnection which have fixed predetermined positions in relation to the panels
themselves, irrespective, so far as possible, of variations in, for example, angular
relationships between adjoining panels.
[0007] In the embodiment illustrated, the connection between adjoining panels is by way
of hinge members carried by adjoining panels, with the respective line of interconnection
between adjoining panels being determined by the pivotal axis of cooperating hinge
members, as disclosed in detail below.
[0008] Figure 5 illustrates the form of a single such hinge member, referenced 30. Figure
5a is an end elevation view of a member 30, Figure 5b is a rear elevation view of
the member 30, Figure 5c is a side elevation view and Figure 5d is a front elevation
view of member 30. Figure 5e is an elevation view from the opposite end from Figure
5a and Figure 5f is a view in longitudinal section of the member 30. As shown, such
member 30 comprises an elongate body part 32 adapted to be secured to a respective
edge of a respective panel proper, the body part 32 having, integrally formed therewith,
a laterally projecting ring or eye 34 defining a bearing aperture 36 (see Figure 5a).
The central axis of the aperture 36 is parallel with the longitudinal dimension of
the part 32 and the length of the ring 34, measured along this axis, corresponds with
one sixth of the axial length of the part 32 (minus a predetermined dimension for
clearance purposes). The system utilises three different types of connector elements,
each with its respective ring 34 projecting therefrom at a different one of three
axial positions along the part 32, as indicated at A, B and C in Figure 5, the pitch
between the three positions corresponding to 1/6 of the effective length of the element
32. As the hinge members, apart from the rings 34, are substantially symmetrical about
the median centre line shown extending vertically in Figures 5a, 5b and 5d, it is
possible, in effect, to obtain six different locations of ring 34 relative to member
32 taking account of the possibility of reversing the members 30. In the type of element
shown in solid lines in Figures 5c and 5d and 5f, the outer end of the ring 34 has
a counter-recess 42 formed therein, which is substantially circular in plan apart
from a flat, indicated at 44 in Figure 5a extending chordally across the peripheral
wall of the counter-recess. This flat 44 cooperates with a complementary flat on a
retaining flange at one end of the hinge pin (see Figures 10a to 10d) used to connect
cooperating members 30 of adjoining panels together as explained below.
[0009] Referring to Figure 4, each panel, referenced 64, comprises a wooden frame with honeycomb
core, with skins of MDF or similar material pressed and adhered to the frame. The
frame is provided with a central groove on the outside edge, on all four sides. This
groove, on any such side, may receive a tongue 46 of a connector strip for example
of aluminium alloy, having a body portion 48. Such connector strips are formed, for
example, as extrusions of aluminium alloy having the constant cross section shown
in Figure 4. Figure 15 shows such a strip, in cross section, in greater detail.
[0010] Referring again to Figure 5, it will be noted that the body part 32 of each member
30 forms a longitudinally extending channel, on the side of the part 32 remote from
the ring 34, said channel including an outer region 52 and an inner region 54 separated
by inwardly extending ribs 56 on either side of the channel, the part 32 having inwardly
projecting flanges 58 which define a restricted longitudinally extending opening to
the channel portion 52. Midway along the part 32, a transverse web 60 extends across
the channel portion 54 for reinforcement purposes. The channel portions 52, 54, and
the inner edges of ribs 56, 58, preferably converge slightly from the free ends of
the part 32 to the plane of web 60.
[0011] The form of the head portion 48 of the connector strip is such as to be received
snugly within the channel portion 52 but to project sufficiently far between the ribs
56 to interfere with the web 54. Consequently, whilst a length of connector strip
may be extended into a body 32 from either end thereof, the member 32 is not entirely
free to slide along the connector strip so that each connector member 32 is located
longitudinally with respect to the panels to which it is fitted by two lengths of
connector strip extending into the member from either end thereof, to engage the web
60. The members 30, with intervening fill members 70 (see below), are fitted to the
vertical edges of the panels 64 at the upper and lower ends of such edges. In assembly,
a respective fill member 70 is slid along each panel vertical edge, on the respective
strip 46, 48, to an intermediate position along such edge, leaving end portions of
the respective strip 46 and 48 exposed. The hinge members 30 are then fitted over
the end parts of the respective strips 46, 48 and pushed into their final positions
in which their respective webs 60 engage the respective (slightly inset) ends of the
respective strips 48. Thus, for each panel, the respective members 30 project by half
of their axial extent above and below the upper and lower edges of the respective
panels. The rings 34, in superimposed relationship, of the hinge members of the panels
to be interconnected along a common vertical axis, are connected at the upper and
lower ends of the panels respectively by upper and lower hinge pins (see below) passed
through the aligned rings 34. For assembly reasons, in view of the use of headed hinge
pins retained by circlips at their lower ends, the desired hinge members 30 are preferably
interconnected by their respective hinge pins before fitting to the edges of their
respective panels.
[0012] Referring to Figures 5a to 5f, each body part 32, externally, has two planar side
faces 68 which converge, as shown in end view in Figures 5a and 5c, towards the axis
of the ring member 34, the included angle between these side faces being 60
° or slightly less. As shown in Figures 4 and 6g each fill member 70 has a cross section
similar to that of the body portion 32 but, in this case, the mutually inclined side
faces actually meet along a line which, in the assembled display, lies on the axis
of adjacent members 30. For convenience, the channel parts of the members 70 and the
flanges and ribs thereof, which correspond with the channel parts, flanges and ribs
of the members 30, have the same references. In the members 30, the body part 32 terminates,
at its closest approach to the axis of ring member 34, in a concave cylindrical surface
centred on that axis and at a radius corresponding substantially with the radius of
each ring member 34.
[0013] In assembly of a display using the system of the preferred embodiment, the panels
at each level are assembled before fitting the panels of the next panel above. Thus,
the panels of each row above the first are fitted between the upwardly projecting
halves of the members 30 carried by the row of panels below, with the ends of the
strips 46, 48 of the upper panels being fitted in the channel parts 52 of the upwardly
projecting halves of the members 30 carried by the lower panels.
[0014] In addition to the solid panels described above and shown in Figure 7, the preferred
display system also includes rectangular frames, in the same modular sizes as the
solid panels and which may carry posters, for example or glass or clear plastics "glazing"
sheets. Such frames are assembled using extrusions identical with the infill members
70 as the vertical frame members and rails of a cross section shown in Figure 8 as
the horizontal frame members.
[0015] In such frames, the horizontal rails 80 are connected at their ends to the respective
members 70 by screw and nut clamping arrangements as illustrated in Figure 12. The
screws in such screw and nut arrangements may be, for example, hexagon socket screws.
[0016] Referring to Figures 8 and 13, each horizontal rail 80 comprises two parallel transversely
spaced vertical webs 82 connected by an intermediate horizontal web 84 from which
project, at positions intermediate the web 82, a pair of upwardly extending inner
webs 86 and a pair of downwardly extending inner webs 86, the webs 86 being parallel
with the webs 82 and each upwardly extending web 86 being in substantially the same
plane as a respective one of the downwardly extending webs 86. The webs 86 extend
upwardly and downwardly slightly further than the webs 82 and each web 86 carries
along its free edge a respective flange or lip directed towards the opposing web 86
on the same side as the web 84 whereby there is formed, above and below the web 84
in each member 80, a central channel, (defined between the respective pair of webs
86) having a restricted mouth, bounded on either side by a respective side channel
(defined between the respective web 86 and the adjoining part of the adjacent web
80). Figures 14a to 14e illustrate one component of the screw and nut connection used
to connect an end of a rail 80 to the adjoining member 70. This component effectively
forms a nut having an elongate rectangular head 90 adapted to fit snugly within the
channel part 52 of the member 70 and having a rectangular spigot 92 extending from
the head portion 90 at right angles thereto. A screw threaded bore extends through
the head portion 90 and the spigot 92, along the axis indicated at 94 in Figure 14b
to receive a screw 96 (see Figure 12). The width of the spigot portion 92 corresponds
substantially to the spacing between adjacent webs 86 in the rail 80. As shown in
Figures 14c and 14d, a horizontal slot extends through the spigot 92 from its free
end to a position closely adjacent the head 90. The end portion of each rail 80 is
prepared by eliminating the portion of the web 84 lying between the webs 86 over a
predetermined distance from the free end of the rail 80 to form, as viewed in plan
(Figure 12) an elongate slot to receive the shank of screw 96, and eliminating the
webs 86 and a slightly larger part of the web 84 at an intermediate position along
said elongate slot to accommodate the head of the screw 96. The shank portion 92 fits
snugly between the webs 86, the slot receiving the residual portions of the web 84
between the opposing webs 86. The nut 90 thus serves to locate the screw 96 with its
axis lying in the plane of the web 84. With the nut and screw thus assembled to the
end of rail 80, the head 90 can be slipped into the channel 52' of the adjoining member
70 from the free end of the latter, whereafter, by tightening the screw 96 using an
appropriate tool, for example a hexagonal key, the head portion 90 of the nut may
be drawn towards the rail 80 until the flanges 58 of the member 70 are clamped firmly
between the head 90 and the end of the rail 80. A spigot 81 (see below) may be located
relatively loosely by the free end of the shank with the screw 96 extending therethrough
an aperture provided in such spigot.
[0017] Lengths of a glazing strip, formed as a plastics extrusion of the cross section shown
at 100 in Figure 13 (shown to a larger scale in Figure 9) are mounted on the vertical
and horizontal members of the frames. These glazing strips are constructed to support
plastics or glass glazing panels or other infill panels. The extrusion 100 comprises
a base portion 102 adapted to fit snugly within the outer portions of the channels
defined between opposing webs 86 and likewise to fit in the channel parts 52 of the
members 70. The extrusion 100 further comprises opposing web formations 104 extending
from such base portion 102 and defining a channel to receive plastics or glass glazing
strips, or the like. Each extrusion 100 has, on each side of its base portion, a respective
groove to receive the respective flange of the respective web 86, or the respective
flanges 58 of a member 70 whereby each strip of extrusion 100 is held snugly within
its respective channel. The lengths of extrusion 100 are, of course, fitted into such
channels by longitudinal sliding and are so fitted before the frames are assembled.
The ends of such strips 100 are mitred as shown in Figure 13a. The dimensions of the
base portion of the extrusions 100 are such as to provide clearance between the base
portions and the nut shanks 92 at the ends of the horizontal rails 80.
[0018] As shown at the intermediate level in Figure 13, the horizontal beams 80 also provide
a means of supporting horizontal members of the system, for example shelves, by providing
the latter with downwardly directed hooks or flanges which extend into the outer channels
of the rails 80 (defined between the upper webs 86 and the upper portions of the webs
80). As shown also in Figure 13, infill panels 110 may be fitted into such frames
by having their edges accommodated within the outer channels of the horizontal rails
and abutting or closely approaching the outer faces of the flanges 58 of the members
70.
[0019] The horizontal rails 80 may likewise be utilised to fill in the spaces defined, at
the top of the panel assembly, between the upwardly projecting portions, from the
uppermost row of panels, of the uppermost members 30. The nut and screw clamping arrangement
may be used to clamp the ends of the horizontal beams 80 to the members 30 in much
the same way as to the members 70 forming the vertical limbs of the rectangular frame.
[0020] A similar provision may be made at the lower ends of the panel assembly.
[0021] The frames shown in Figure 18 have spigots 81 projecting upwardly and downwardly
from the upper and lower ends of their respective members 70. These spigots 81 engage
in the channel parts 54 of the members 30 fitted to superimposed or underlying panels
of the type shown in Figure 7, in an assembled display, or into frames corresponding
to those shown in Figure 18 but without such spigots (not shown), or into intervening
infill panels. The spigots 81 at the top and bottom of a display may also engage in
grooves formed in the foot pads 107 or connector caps 107.
[0022] The spigots 81 (see Figure 17) are inserted into the channel parts 54 of the members
70 from which they project and are retained by the end of the respective screw 96
which projects through a transverse bore 83 in the spigot 81.
[0023] Referring to Figures 10a to 10d each of the hinge pins referred to comprises a tubular
externally cylindrical body or shank 120 dimensioned to fit snugly within the rings
34, a head 122 at one end of the shank which is in the form of a circular plate with
a flat cut along one side and is adapted to fit snugly and non-rotatably within the
recess 42 in an outermost ring member 34 to be held non-rotatably therein. At the
opposite end of the shank 120, a groove 124 is provided to receive a retaining circlip
(not shown). As shown in Figure 10d, the central bore, extending through the shank
portion 120 and head 122 is screw threaded from either end of the hinge pin, to receive,
where appropriate, a correspondingly screw threaded stud 106 on an upper or lower
foot pad or connector cap 107 (according to whether the item 107 shown in Figure 11
is fitted at the upper or lower end of the assembled panel system). The screw threaded
interengagement between the foot pad or cap and the hinge pin allows for vertical
adjustment of the foot pad or cap relative to the remainder of the panel system to
adapt to uneven floor surfaces. The cap has, on its side nearer the panel system,
in use, i.e. the side from which the threaded stud extends, circumferential grooves
adapted to receive the projecting portions 31 of the connector body parts 32.
[0024] In the same manner as the shelves may be mounted, ceiling panels may be extended
between rails 80 carried by transversely spaced panels, at the upper end of the display
structure.
[0025] The infill members 70 may be used as trunking to carry electrical cabling unobtrusively
(within their inner channels 54).
[0026] The preferred system according to the invention allows up to six adjoining panels
at the same level to be connected at a common vertical axis, the panels radiating
from said axis (see Figure 2). In the simplest arrangement illustrated (in plan and
side view, in Figure 6b), where two adjacent panels only are to be interconnected,
the adjacent panels are provided, on their adjacent edges, with respective hinge members
30 having their rings 34 displaced relative to each other, so that, in the assembled
condition, the rings 34 of the members 30 of the two panels lie one above the other,
the body parts 32 of the adjoining hinge members of the adjoining panels being, of
course, at the same level as each other. The otherwise unoccupied portions of the
axial length of the two adjoining parts 32 is occupied by spacer rings 111 which are
fitted over the respective hinge pins in the appropriate number, so that, for example,
where only two hinge members are interconnected, four such spacer rings are required.
Similarly, where three adjoining panels are to radiate from a common vertical axis,
(see Figure 6c), three interconnected hinge members 30 are utilised having their rings
34 at three different axial positions relative to the "common" axial extent of the
body parts 32 of the three members, the axial space unoccupied by the rings 34 being
occupied by spacer rings (in this case three in number). In the same way, as shown
in Figures 6d to 6f, four, five or six hinge members may be interconnected, using
two, one or no auxiliary rings to occupy the otherwise unoccupied space on the hinge
pins.
[0027] Whilst, for convenience, the term "hinge member" has been used in relation to the
components 30, 32, 34, it will be appreciated that, in practice, once a chosen display
is assembled, there will not normally be pivotal movement between adjoining interconnected
panels and indeed, where six adjoining panels are so interconnected, such pivotal
movement is substantially excluded because there is no freedom for any significant
pivotal movement between the members due to the interaction between the inclined vertical
flanks of the various body parts 32 and infill members 70. On the other hand, it may
well be desired to build a structure having a door and this can, of course, be done
simply by providing a standard panel, or two or more superimposed standard panels
connected along one vertical edge only by hinge members 30 to the adjacent stationary
panels and bearing on the other vertical edge, a member or members 70 to which may
also be fitted a handle attachment and/or a catch attachment.
