Description
[0001] The present invention relates to the field of storage cases,
and more particularly to storage cases suitable for the storage of
a folded display stand.
[0002] Folding display stands are commonly used at exhibitions,
trade fairs and so on. They typically comprise a lightweight
folding metal framework which can be covered with graphics (being
printed display material similar to posters).
[0003] In the particular application of small folding display
stands, the display stand should be capable of being transported,
assembled and disassembled by a single person. For this reason, the
display stand should be capable of being transported in the boot
(trunk) of a car.
[0004] It is preferable to transport and store the folded display
stand in some sort of case, to protect both the frame and the
graphics from damage.
[0005] During the exhibition, the case needs to be either hidden or
disguised, since otherwise it would represent unnecessary and
unsightly clutter, which would detract from the visual appeal of
the stand. Some cases are used as counters or display items in
themselves, if they are wrapped in a graphic.
[0006] However, known cases for such display stands have a number
of drawbacks. While a single frame may be used for many
exhibitions, it may be necessary for different sets of graphics to
be used. Typically, the storage case contains the graphics rolled
up, with the folded frame placed in the void in the centre of the
rolled graphics. To interchange two sets of graphics, therefore,
requires the case to be unpacked, the graphics removed, a
replacement set of graphics to be rolled up and placed in the case,
and the frame placed inside. Once this has been repeated a number
of times, it is clear that the graphics, and the frame, may suffer
damage from excessive handling.
[0007] A known alternative, to provide a dedicated case and frame
for each set of graphics, may be prohibitively expensive.
[0008] In addition, the mere fact of storing the folded frame in
the centre of the roll of graphics may cause damage to the graphics
during transport and storage.
SUMMARY OF THE INVENTION
[0009] The invention therefore provides a modular storage case with
separable cases for the frame, and for the graphics. The graphics
case may be interchanged with other graphics cases for transport to
a different exhibition, while avoiding the need to unpack any of
the cases. This reduces damage to the graphics and the frame by
reducing the amount of handling required.
[0010] A second aspect of the invention relates to the avoidance of
damage to either or both of a frame, and a roll of graphics. One or
more packing pieces may be provided in each graphics and/or frame
case, to prevent the folded frame or other equipment from moving
within the respective case, when it is handled.
[0011] In accordance with the present invention, there is provided
a modular storage case for storage of a folded display stand,
comprising a graphics storage case, having a substantially
cylindrical internal storage space; a first frame storage case,
having an external cross-section which is complementary to an
external shape of the graphics storage case; closure means for
closing the graphics storage case and the frame storage case; and
fastening means for detachably fastening the graphics storage case
to the frame storage case.
[0012] The modular storage case may further comprise a second frame
storage case, having an external cross-section which is
complementary to the external shape of the graphics storage case;
further closure means for closing the second frame storage case,
and further fastening means for fastening the second frame storage
case to the graphics storage case, at a location separated from the
first frame storage case.
[0013] In either example, the closure means may incorporate the
fastening means.
[0014] The closure means may comprise end pieces of suitable shapes
for the graphics case, and the frame case, and the fastening means
may take the form of co-operating features of the respective end
pieces. If so, an end-piece for the graphics case may comprise a
cylindrical, and/or truncated conical, boss on its internal
surface, for retaining stored graphics, at least part of the
external surface of the end-piece comprising a cavity corresponding
to at least part of the boss. Furthermore, the end-piece for the
frame storage case may comprise an overlap portion, not required
for closing the frame storage case; the overlap portion being sized
to overlap at least part of the cavity of the end-piece of the
graphics case when the cases are placed together. The overlap
portion may comprise a retaining lug suitably dimensioned to locate
within the cavity, when the cases are placed together, thereby to
engage the cases to each other. The upper end pieces may be
dimensioned such that the overlap portion has a thickness
substantially equal to the depth of a recess of corresponding shape
located in the graphics case end-piece, whereby the two end-pieces,
when engaged, form a substantially flat upper surface.
[0015] Similar arrangements of end-pieces, cavities, overlap
portions and retaining lugs may be provided at corresponding upper
and lower ends of the graphics case and the frame case.
[0016] The closure means may be lids attachable to the respective
cases. Alternatively, the closure means may be moulded features,
moulded unitarily with at least part of the respective case. The
closure means may comprise at least one lid attachable to one of
the graphics case and the frame case, and at least one moulded
feature, moulded unitarily with at least part of the respective
frame case or graphics case.
[0017] The lower end piece of at least one of the frame case and
the graphics case may carry wheels for transporting the case.
[0018] The graphics case may have a substantially cylindrical outer
surface. If so, the frame storage case may be substantially
cylindrical, having a parallel, part cylindrical recess to
complement the cylindrical outer surface of the graphics case.
Alternatively, the frame storage case may be shaped to have a
recess to complement the cylindrical outer surface of the graphics
case, and also shaped such that the frame storage case and the
graphics storage case, when engaged, form a substantially prismatic
structure, with a cross-section which is substantially oval, ovoid,
or comprising two semicircular rounded parts joined by
substantially straight sides.
[0019] The frame case and/or the graphics case may be provided with
at least one reusable packing piece for retaining equipment within
the case.
[0020] The present invention also extends to a storage case for
storage of a folded display stand, comprising at least one reusable
packing piece for retaining equipment within the case.
[0021] The present invention also extends to a reusable packing
piece for use in retaining equipment within a case for storage of a
folded display stand. The packing piece may comprise at least one
cut-out for retaining parts of the equipment, and/or at least one
recess for retaining further parts of the equipment, when the
equipment and the packing piece are located within the case.
[0022] The packing piece may be constructed from a compressible
material. In its uncompressed state, the packing piece may have at
least one diameter which is greater than a corresponding internal
diameter of the case, whereby the packing piece may be compressed
into engagement with an internal surface of the case.
[0023] The reusable packing piece may be for restraining equipment
within a roll of graphics, the packing piece having an
essentially-cylindrical shape, with at least one cut-out provided
therethrough.
[0024] The packing piece may be constructed from a compressible
material. In its uncompressed state, it may have at least one
diameter which is greater than a corresponding internal diameter of
roll of graphics, whereby the packing piece may be compressed into
engagement with an internal surface of the roll of graphics.
[0025] The reusable packing piece may be made of polyurethane foam
or polyvinyl chloride foam or other plastics foam.
[0026] The reusable packing piece may comprise at least one cutout
forming a handle for manipulation of the packing piece
[0027] The present invention also extends to modular storage system
comprising a modular storage case according to any described
embodiment, together with one or more further graphics storage
case, the graphics storage cases being interchangeably fastenable
to the frame storage case.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
[0041] The invention provides a modular storage case with separable
cases. Typically, one case stores the frame, while another stores
the graphics. The graphics case is interchangeable with other
graphics cases for transport to a different exhibition, while
avoiding the need to unpack any of the cases. This reduces the
likelihood of damage to the graphics and the frame by reducing the
amount of handling required. Similarly, the invention also provides
a modular storage system, which includes at least one frame storage
case, and a number of interchangeable graphics storage cases.
[0042] FIG. 1 shows basic a modular storage case according to an
embodiment of the present invention. As illustrated, a graphics
case 1 and a frame case 2 are provided.
[0043] The graphics case body 10 should be cylindrical, or at least
should have a cylindrical inner cavity. This is to allow the
graphics to be effectively rolled up and stored. The cylindrical
inner cavity may be defined by a continuous cylindrical wall, or by
a number of ribs tangent to an imaginary cylindrical surface.
[0044] According to an aspect of the present invention, the frame
case body 20 has an external cross-section which is complementary
to the shape of the graphics storage case body. That is, in the
illustrated embodiment, a part cylindrical recess 22 is provided,
which is shaped to accept a part of the outer surface of the
graphics case body 10. The graphics case body and the frame case
body are separable and independent. End pieces 14, 16 are provided
for closing upper and lower ends of the graphics case body. End
pieces 24, 26 are provided for closing upper and lower ends of the
frame case body.
[0045] In use, a roll of graphics is placed inside the graphics
case 1. The cylindrical inner cavity holds the roll in a stable
position, and protects it from damage. Preferably, nothing else
which could cause damage to the graphics is stored in the graphics
case. The folded frame is stored in the frame case 2. Packing
materials may be provided within the frame case to prevent the
frame from moving about inside the case, thereby protecting both
the frame and the case from damage.
[0046] The frame case 2 may be detached from the graphics case 1
and attached to a similar graphics case containing an alternative
set of graphics. This enables the graphics to be changed without
requiring them to be unpacked, reducing the likelihood of
damage.
[0047] Preferably, in a typical usage of the modular storage case
of the present invention, nothing else should be stored in the
graphics case. The graphics may be permanently stored in the
graphics case, further reducing the risk of damage. The graphics
case may be suitably labelled to identify the set of graphics it
contains, facilitating retrieval of the graphics, and reducing the
risk of damage since it is not necessary to sort through a large
number of stored graphics in order to retrieve a desired set.
[0048] According to a further aspect of the present invention, it
may be necessary to store a frame, or frame parts or accessories,
with the graphics, in the graphics storage case. In such
embodiments, packing pieces are provided to securely locate the
frame, or parts and accessories, so that they do not contact the
graphics, eliminating potential damage to the graphics, and so that
they do not move about inside the case when it is handled, reducing
the risk of damage to the frame or the parts or accessories
themselves. For example, if a particularly small display stand is
to be stored, the graphics and the frame may both be stored within
the graphics case. Alternatively, with a larger display stand, it
may be necessary to store some parts of the frame within the
graphics case, if the frame case has insufficient capacity to store
all of the required frame parts.
[0049] According to a related aspect of the invention, a modular
storage case system comprises a frame case and a number of
interchangeable graphics storage cases.
[0050] Referring again to FIG. 1, end pieces 14, 16, 24, 26 serve
to close the ends of the case bodies, and to protect the contents.
Preferably, as will be described in detail below, the end pieces
also provide means for engaging and fastening the frame case with
the graphics case.
[0051] FIG. 2 shows a cross-section of an embodiment of lower end
pieces 16, 26, which, in this embodiment, serve to close the lower
end of the associated case bodies and also to engage the cases
together.
[0052] End piece 16 comprises a cylindrical, conical,
truncated-conical, or other shaped boss 18 on its inner surface.
End piece 26 needs no such boss, since it serves to close the frame
case, in which no rolls are stored, and which does not require any
cavity to be provided on its external surface, as described
below.
[0053] A part of the external surface of the graphics case end
piece 16 comprises a cavity 19 whose shape corresponds to the
corresponding part of the boss 18, preferably to form a constant
wall thickness w in the region of the boss.
[0054] The lower end-piece 26 for the frame storage case includes
an overlap portion 32, which is not required for closing the frame
storage case, since it lies outside of the perimeter of the frame
storage case body, shown by the location of the walls of the case
body 20.
[0055] The overlap portion 32 is sized to overlap a part of the
end-piece of the graphics case, including at least part of the
cavity 19, when the cases are placed together. The overlap portion
also comprises a retaining lug 34, which is suitably dimensioned to
locate within the cavity 19, when the cases are placed together.
The lug 34 which engages within the cavity 19, serves to engage the
graphics case and the frame case to each other.
[0056] The boss 18 allows space for a retaining lug 34 of
sufficient size to be accommodated within cavity 19, while
nevertheless ensuring that a roll of graphics 40 can be
accommodated in a case of minimum height. The minimum height
requirement serves several purposes. There is a maximum height of
case that can still fit in the boot (trunk) of a car. A case of
this maximum height should be able to accommodate the tallest
possible roll of graphics. Therefore, it is important that the roll
of graphics 40 should extend as close to the end of the case as
possible. A roll of smaller graphics could be stored inside the
roll 40, the end of the roll of smaller graphics resting on top of
the boss 18.
[0057] The boss 18 therefore allows the roll of graphics 40 to
extend as low in the case as possible, while still providing a
cavity 19. The boss may also provide a support for any frame pieces
of accessories which the user may choose to store in the centre of
the roll 40, as will be further described below.
[0058] Preferably, similar end pieces with similar cavities,
overlap portions and retaining lugs are provided at corresponding
upper and lower ends of the cases. Then, the retaining lug 34 at
each end will be retained in its cavity by the action of the
retaining lug and cavity of the other end.
[0059] Alternatively, the upper end-piece of the graphics case may
have a cavity, and corresponding boss on the internal surface, of
only sufficient size to accommodate a retaining lug 34. In such an
embodiment, the space around the small boss may be used for storage
of ancillary equipment and accessories, while a flat plate or foam
layer is provided to retain the ancillary equipment and
accessories, while providing a safe surface for contacting the end
of the roll of graphics 40 without causing damage.
[0060] As illustrated in FIG. 2, the outer surface of the end piece
for the graphics case may include a recess 36, whose size, location
and depth at least correspond to the size, location and thickness
of the overlap portion 32 of the end piece for the frame case. This
ensures that the graphics case will be stable when stood on end. In
a similar case of an upper end piece having recess only sufficient
to accommodate the retaining lug, the two end-pieces, when engaged,
form a substantially flat upper outer surface.
[0061] The substantially flat outer surface at the upper end of the
cases will allow their top surfaces to be used as a counter on an
exhibition stand.
[0062] FIGS. 3, 4 respectively show outer and inner surfaces of the
end pieces of the graphics case and the frame case, when in
engagement, such as shown in FIG. 2.
[0063] FIG. 5A illustrates an end piece for a frame case,
particularly suitable for the lower end. It is similar to the one
shown in FIG. 2. In this embodiment, the end piece is unitarily
moulded (eg from a plastics material) with the lower part of the
case body 20.
[0064] FIG. 5B illustrates an alternative end piece 24 particularly
suitable for the upper end of a frame case. While still similar to
the end-piece shown in FIG. 2, this end piece is in the form of a
detachable lid for the upper end of the frame case. The retaining
lug 34 and overlap portion 32 are as shown in FIG. 5A. The lid
further comprises wall portions 20' which may form part of the wall
of the case. A ridge or groove may be provided around the surface
21 to engage with a corresponding groove or ridge in the remainder
of the wall portion 20. Alternatively, the wall portions 201 of the
lid may be designed to slip over or partially inside the wall 20 of
the case. Fastening means 23 should be provided to retain the end
piece (lid) in position. This may be a latching clamp, as
illustrated. This may also be lockable for security reasons.
Alternatively, straps with buckles or "Velcro"-type fastenings may
be used, or features may be included in the lid and body to provide
a snap-fit mechanism.
[0065] From consideration of FIGS. 1 and 2, it is clear that, by
placing the lid 24 in position, with its retaining lug in the
cavity 19 of the graphics case lid (14, FIG. 6C), both the graphics
case and the frame case are retained together and closed by their
respective lids. The fastening means 23 then serves to hold the
entire assembly together.
[0066] FIG. 6A shows a general end piece 14 for the graphics
container. A cavity 19 is provided, and is at least sufficiently
large to accommodate the retaining lug 34 of the corresponding end
piece of the frame case. Recess 36 is provided, to accommodate the
overlap portion of the frame case. Cavity 19 extends into the
graphics case, and is encased within a boss 18. Boss 18 may be a
full cylindrical and/or truncated conical boss, as shown.
Alternatively, the boss may be only as large as necessary to
accommodate recess 19 with a wall thickness w. In use, the
remainder of the surface of the end-piece 14 will serve either as a
part of a substantially flat upper surface, which may be used as a
counter, or serves as a lower surface on which the graphics case
can stably rest when stood on end.
[0067] FIG. 6B shows a lower end-piece for the graphics case. In
this example, the end piece is unitarily moulded with part of the
graphics case wall 10. In this example, the boss 18 is a
truncated-conical boss as discussed above. The cavity 19 occupies
substantially all of the boss 18, and is correspondingly
truncated-conical in shape. The recess 36 provided to accommodate
the overlap portion 32 of the frame case here extends over the
entire area corresponding to the graphics case wall 10. Protrusions
31, 31' are provided on opposite sides of the end-piece. The lower
surface of these protrusions serve as a stable base for standing
the graphics case on end. One protrusion 31 carries wheels 33 for
use in moving the case. The other protrusion 31' serves as a rest.
Preferably, the protrusions align with similar protrusions on the
base of the frame case to provide a pleasing appearance when the
cases are assembled together.
[0068] FIG. 6C shows an upper end-piece 14 for the graphics case.
In this example, the end piece is in the form of a detachable lid.
In a particular embodiment, the lid may be used as a step stool to
aid the assembly of the exhibition stand. Here, the cavity 19 is
only large enough to accommodate the retaining lug 34 of the frame
case. The boss 18 inside the lid is only large enough to
accommodate the cavity 19. Similarly, the recess 36 is only large
enough to accommodate the overlap portion 32 of the frame case.
[0069] Protrusions 35, 37 are provided on opposite sides of the
lid. Protrusion 37 may comprise a handle, and should be arranged to
locate on the same side of the graphics case as the wheels 33 of
FIG. 6B. Protrusion 35 is preferably provided, to increase the
upper surface area of the case for its use as a counter, and to
increase the visual appeal of the case. Protrusions 35, 37
preferably align with respectively similar protrusions on the lid
of the frame case.
[0070] FIG. 7A shows a perspective view of a graphics case and a
frame case according to a certain embodiment of the invention. The
frame case and the graphics case are each shown assembled, but not
linked together. Ribs 27 are shown, which protrude into the
graphics case and serve to define the substantially cylindrical
internal storage space by an imaginary cylindrical surface tangent
to the internal extremities of the ribs 27.
[0071] FIG. 7B illustrates the action of closing the frame case
such that the overlap portion 32 of the end piece 24 of the frame
case 2 engages into the recess 36 of the end piece 14 of the
graphics case 1. The retaining lug 34 locates within the cavity 19,
thereby to engage the cases to each other. Fastening means 23 are
then fastened, to retain the cases together, and to retain both end
pieces 14, 24. A corresponding lug 34 on a corresponding overlap
portion 32 at the lower end of the frame case 2 will already have
been engaged into a cavity 19 at the lower end of the graphics
case.
[0072] If the modular storage case of the invention is to be used
as a counter, or other display piece for the stand, it should be
wrapped in a graphic. The graphics case will have a height
approximately corresponding to the height of the roll 40 of
graphics, and so also corresponding to a dimension of a graphic.
The outer surfaces of the modular storage case are preferably
smoothly curved, to allow a graphic to be displayed in a pleasant
manner, while avoiding damage to the graphic. The embodiments shown
in FIGS. 1 and 7 fulfil these requirements by having a
substantially prismatic structure, in this case having a cross
section corresponding to two overlapping circles, or two
semicircles joined by straight sides, respectively.
[0073] Other embodiments of the invention may be provided, while
still fulfilling the above requirements. For example, prismatic
structures may be provided, having a cross section which
corresponds to an oval, or an ovoid. In each example, however, the
graphics case should have a cylindrical inner space for the storage
of the graphics. This may mean that the graphics storage case has a
wall of varying thickness, or that the frame case is of an exotic
cross section to accommodate a cylindrical graphics storage case to
provide the required shape of the combined storage case.
[0074] In any of the above-described embodiments, and as further
described below in relation to a further aspect of the present
invention, either or both of the graphics case and the frame
storage case may contain packing material for retaining a frame, or
other equipment, to avoid damage both to such equipment, the case,
and any graphics or other materials stored in the case. Several
interchangeable sizes of packing pieces may be provided, to allow
for storage of several different shapes of frame.
[0075] In a variant of the modular storage case of the present
invention, two frame storage cases may be provided for each
graphics storage case. For example, this would enable two
exhibition frames and associated graphics to be stored and
transported together, typically two complementary frames and sets
of graphics, which make up a single, larger, stand. The graphics
case would, of course, need to be large enough to hold two sets of
graphics. To provide such a modular case, the overlap and
engagement features of the end pieces, if used, should be repeated
on opposite sides. That is, the recess 36 and cavity 19 should be
provided on two, preferably diametrically opposed, parts of each
end piece for the graphics case. Similarly, the overlap portion 32
and engagement lug 34 should be provided on two, preferably
diametrically opposed, parts of each end piece for the frame case.
Suitable arrangements must be made for all handles and wheels, if
provided, to appear on the same or both sides of such a modular
case. Even in such an embodiment, the case is preferably still
small enough to fit into the boot of a car.
[0076] In any embodiments using recesses, cavities, lugs and
overlap portions, filler pieces may be provided, corresponding to
the overlap portion 32, including the lug 34, for use in obtaining
flat outer surfaces to the end pieces of the graphics case, when
the frame case(s) is/are not engaged to the graphics case.
[0077] In certain embodiments of the invention, the end pieces,
being closure means for closing the upper and lower ends of the
case walls, may be moulded unitarily with at least part of the
respective case. Alternatively, the various end-pieces may be lids
attachable to the respective ends of the respective cases.
[0078] In alternate embodiments of the modular storage case of the
invention, the overlap portions 32 and recesses 36 may take shapes
other than that defined by overlapping circles shown in the figures
In addition, the cases may be engaged to one another by other
means, such as other forms of co-operating features of the end
pieces; mechanical latches on the end pieces or on the walls; or
straps and buckles, recessed into the outer surfaces of the case to
allow a graphic to be wrapped around the outside of the case
without being deformed by the straps or buckles.
[0079] The end pieces may be attached to the case walls by the
clamps or latches described above, straps with buckles,
"Velcro"-type fasteners or a snap-fit mechanism.
[0080] In certain embodiments of the invention, the end pieces for
the lower end of the graphics case and the frame case may be
provided with wheels to facilitate transport. Similarly, the case
walls may be provided with carrying handles.
[0081] In any of the above-described embodiments, and as further
described below in relation to a further aspect of the present
invention, either or both of the graphics case and the frame
storage case may contain packing pieces for retaining a frame, or
other equipment, to avoid damage both to such equipment, the case,
and any graphics or other materials stored in the case. Several
interchangeable sizes of packing pieces may be provided, to allow
for storage of several different shapes of frame.
[0082] FIG. 8 shows an embodiment of storage cases according to an
aspect of the present invention. Reusable packing pieces 50, 60 are
located within the upper end pieces of the frame case and the
graphics case, respectively. Each reusable packing piece may be
made from a foam material such as polyurethane or other closed cell
plastics foam. Typically, each packing piece will comprise a recess
52, 62 suitably dimensioned to retain an end of a folded frame
stored within the respective case. Preferably, as will be further
explained with reference to FIGS. 11A and 11B, the packing pieces
preferably do not fill the entire cross-section of the respective
case, but voids may be included in the material of the packing
piece, or around the edges, to provide a handle for easy insertion
and removal of the packing pieces, or to allow lengthy pieces of
equipment to be stored, protruding through the voids in the packing
piece, yet still restrained from excessive movement.
[0083] The packing pieces may be adapted to restrain other types of
article, not necessarily folded frames, within the cases.
[0084] As shown in FIG. 8, a space 64 may exist, above the packing
piece 60 in the graphics case 2. This may be used to store small
accessories, fixtures and fittings. Further packing means (eg foam
sheets) may be provided to retain such items in the space 64.
[0085] FIG. 9 illustrates a graphics storage case provided with a
packing piece 70 according to a further embodiment of this aspect
of the present invention. The packing piece 70 may again be
constructed from polyurethane or other closed cell plastics foam.
The packing piece 70 is generally circular, and is designed to fit
within the roll 40 of graphics. The packing piece 70 may have an
external diameter corresponding to the outside diameter of the boss
18. The packing piece includes a hole 72 suitably dimensioned to
accept the frame 80 to pass therethrough. Typically, a folded frame
has an approximately square cross section, and the hole 72 is
shaped accordingly. Of course, if differently shaped folded frames,
or other objects, are to be stored within the roll 40, the hole 72
in the packing piece 70 will be shaped accordingly. If required,
several smaller holes 72 may be provided.
[0086] In an alternative embodiment, packing pieces such as 60 in
FIG. 8 may also be provided in the lower end piece of the graphics
case. In this embodiment, and that shown on FIG. 8, the packing
pieces may have the undesired effect that either full height rolls
40 of graphics cannot be stored, or that the overall height of the
graphics case would have to be increased to accommodate the packing
pieces.
[0087] FIG. 11A shows a plan view of a packing piece 60 installed
within a graphics case 2. The packing piece has a central recess 62
for retaining the folded frame (or other equipment) The packing
piece is shaped to contact the wall 20 of the case at several
points, with voids 68 being provided by cut-outs of the packing
piece. These voids allow long pieces of equipment (eg magnetic
rails used in assembly of the display stand) to be stored in a
controlled manner, preferably separated from contact with the roll
of graphics by careful sizing of the cutouts, and of the roll of
graphics (eg by placing elastic bands around the roll of graphics).
The cut-outs also allow the packing piece to have a sufficient size
(i.e. diameter/circumference) such that the contact points 69 are
compressed into contact with the wall 20, while still allowing the
packing piece to be easily installed and removed. The cut-outs may
be used as handles.
[0088] FIG. 11B shows a plan view of a packing piece 70 for use in
a frame case. It is similar in many respects to the packing piece
60 of FIG. 11A. The packing piece has a central recess 72 for
retaining the folded frame (or other equipment). The packing piece
is shaped to contact the wall 10 of the case at several points,
with voids 78 being provided by cut-outs of the packing piece.
These voids allow long pieces of equipment (eg magnetic rails used
in assembly of the display stand) to be stored in a controlled
manner, preferably separated from contact with the frame stored in
the centre of the frame case 1, by careful sizing of the cut-outs
The cut-outs also allow the packing piece to be sufficiently large
that the contact points 79 are compressed into contact with the
wall 10, while still allowing the packing piece to be easily
installed and removed. A dedicated cut-out 80 may be provided for
use as a handle, or the other cut-outs may be so used.
[0089] FIGS. 12A and 12B respectively show perspective views of the
packing pieces 60, 70 of FIGS. 11A, 11B.
[0090] Although the use of packing pieces as described has been
described in relation to their use in conjunction with a modular
storage case according to an aspect of the present invention, the
use of the packing pieces is in no way limited to such use. Indeed,
the packing pieces as described may be employed with any case for
the storage and transportation of folded display stands. This
applies regardless of whether the frame is stored with, or
separately from, the graphics 40.
[0091] The packing pieces will need to be shaped to fit into
whichever case they are intended to be used with, and will
preferably be provided with recesses to retain the frame or other
equipment that they are intended to work with. The provision of
cut-outs is optional, although they are advantageous in allowing
voids for the storage of lengthy articles, handles for easy
manipulation of the packing pieces, and to allow the packing pieces
to be sized appropriately to be slightly compressed when placed in
the storage case, thereby to retain themselves in position against
the walls of the case.
[0092] The modular storage system of the invention comprises at
least one frame storage case as described, together with at least
two graphics storage cases as described. The graphics storage cases
are interchangeably fastenable to the frame storage case, so that
the frame may be used with one of several sets of graphics without
having to unpack any of the cases.
