Abstract
An expandable framework for attachment of display panels and the like. The linkage is lockable in one or more configurations intermediate the collapsed and fully expanded configurations so that the same framework may be used for more than one type of display, such as floor display and table-top display. A shipping case for containing the framework, when collapsed, is convertible into a podium by wrapping a decorative panel about the case and fastening the panel thereto to be flush with an upper platform on the case.
Description
The present invention relates generally to expandable folding frame portable display structures, commonly referred to in the industry as “pop-ups”, for use in tradeshows, but they may have other purposes.
Examples of such pop-up displays are found in U.S. Pat. Nos. 4,658,560; 4,986,016, 5,125,205; and 4,995,212 which patents are incorporated herein by reference.
Such pop-up displays are available in a variety of either full-height free-standing configurations (such as 10 feet wide curved, 8 feet wide curved, and full-size flatwall) or small table-top configurations (such as 8 feet wide table-top, 6 feet wide table-top, and 6 feet wide flatwall). The full-height displays may have a height of perhaps about 8 feet while the reduced-height table-top displays may have a height, not including a table, of perhaps about 5 feet.
The variety of various pop-up displays on the market utilize various means for holding the frameworks erect in their expanded positions. For example, the aforesaid '560 patent shows at 16 buttons at hubs of its framework to which are attached braces, illustrated at 24 in the '560 patent, for holding the framework in its expanded position, each brace extending between two vertically adjacent hubs. The '016 and '205 patents illustrate another example of holding a framework at an expanded position, i.e., by frame-latching mechanisms, illustrated in FIG. 6 thereof, extending between corresponding front and rear hubs.
It is an object of the present invention to provide a pop-up structure which desirably has versatility for use as more than one version, i.e., such as, for example, a full-height freestanding configuration and a reduced-height table-top configuration.
Both the pop-up display framework, hardware (panel attachment bars), full-size panels for use with the full-height configuration, reduced-size panels for use with the reduced-height configuration, and other components are housed in a wheeled case for storage, shipping, and transport.
It is considered desirable to be able to utilize the shipping case as a podium. Previous efforts to so convert the shipping case have utilized a separate lid or top for hiding or covering up the top of the case and several side pieces or components to visually hide the sides of the case.
It is another object of the present invention to be able to more easily and quickly convert the case to a podium.
In order to provide such a versatile framework, in accordance with the present invention means are provided for locking the linkage in at least one configuration which is intermediate a collapsed configuration and a fully expanded configuration.
In order to convert a shipping case to a podium, in accordance with the present invention a decorative panel is wrapped about the case and is detachably fastened thereto to be flush with a platform thereof.
The above and other objects, features, and advantages of the present invention will be apparent in the following detailed description of the preferred embodiments thereof when read in conjunction with the accompanying drawings wherein the same reference numerals denote the same or similar parts throughout the several views.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 1
to
4
, there is shown generally at
10
an expandable folding frame portable display unit or pop-up display framework which may be used for supporting cladding or graphics, as illustrated by panels
114
in
FIG. 16
, covering the framework when it is in use. The display comprises a plurality of linkages
12
which are pivotly connected at front and rear hubs
14
and
16
respectively for expansion from a compact position for storage and transport, such as illustrated in FIG. 9 of the '016 and '205 patents, to a display position, such as illustrated in
FIGS. 1
to
4
, wherein panels
114
are attached to the front and sides thereof similarly as fabric is illustrated at 70 in FIG. 12 of the '560 patent to be attached to the front of a pop-up framework. Panels may also be attachable to the rear side of the framework. The framework may have open quads, as illustrated, or may have support bracing within quads, such as shown in FIG. 1 of the '560 patent. The framework
10
may be composed of aluminum or other suitable materials.
In accordance with the present invention, braces
18
, which may be called channel bars, struts, or mag bars, extend vertically and may be composed of perhaps three foldably connected portions
19
,
20
, and
21
each of which extends between two vertically adjacent hubs
14
when the framework is in a full-height or fully expanded configuration, as illustrated in
FIGS. 1 and 2
. At least one end portion of each bar portion
19
,
20
, and
21
has a suitable hub attachment means, illustrated at
15
, for detachable attachment of the bar
18
to the vertically aligned hubs
14
so that the framework height is approximately equal to the length of the bar
18
. In addition to holding or locking the framework
10
in the expanded configuration, the mag bars
18
may also serve the purpose of providing magnetic strips, illustrated at
110
in
FIG. 16
, or other suitable means for attachment of panels
114
to the front or rear and sides of the framework, as commonly known in the art. Thus, all of the front vertical rows of hubs as well as the rear vertical rows of hubs at the ends of the framework are shown to be connected by mag bars
18
. However, it should be understood that only a single mag bar is sufficient for maintaining the framework
10
in the expanded condition in accordance with the present invention.
In accordance with the present invention, the uppermost bar portion
19
has an additional hub attachment means, illustrated at
22
, which is located about ⅔ of the distance from the top end thereof, and the middle bar portion
20
has an additional hub attachment means, illustrated at
23
, which is located about ⅓ of the distance from the top end thereof. The attachment means
22
and
23
as well as hub attachment means
15
on end portions of the bar portions may be any suitable means for attachment detachably to the hubs and can be provided using principles commonly known to those of ordinary skill in the art to which this invention pertains. For example, the hub attachment means may be a recess, such as illustrated at 42 in FIG. 11 of the aforesaid '212 patent, which engages a peg, illustrated at 26 in FIG. 5 of the '212 patent, on the respective hub. This peg or button may be shaped to have a mushroom head, as seen at
87
in
FIG. 15
, molded directly with the hub. The front face of the hub may have an aesthetically-pleasing knurled or recessed checkerboard pattern. The mag bar portions may be foldably connected together such as illustrated in FIGS. 11 to 13 of the '212 patent or by other suitable means. Thus, the framework may be erected to the full height of perhaps about
8
feet of
FIGS. 1 and 2
by expanding it to the full height, then connecting the hub attachment means
15
on the end portions of the bar portions to the hubs. The framework may be erected to the reduced table-top height of perhaps about 5 feet of
FIGS. 3 and 4
wherein its height is about ⅔ of its normal full height by expanding or pushing it down to this configuration or allowing it to come down by gravity to this configuration, then attaching the hub attachment means
15
on the upper end portion of the bar portion
19
and the hub attachment means
22
to the upper two hubs
14
respectively and attaching hub attachment means
23
and the hub attachment means
15
on the lower end portion of the middle bar portion
20
to the lower two hubs
14
respectively. The lower bar portion
21
, being foldable relative to the middle bar portion, is folded to underlie the framework or otherwise laid so that it is out of the way.
Alternatively, the bar portions
19
,
20
, and
21
may constitute individual bars which are unattached to each other in which event the lower bar portion
21
would be left out when the framework is erected to the smaller configuration. It should be understood that each bar
18
may comprise any number of connected or individual bar portions depending on the number of quads which the framework has. It should also be understood that, in accordance with the present invention, a single bar portion connecting two hubs may be sufficient to lock the framework in an expanded configuration. Furthermore, the braces
18
may be provided with additional hub attachment means for locking the framework alternately at more than two configurations. Such a system as illustrated in
FIGS. 1
to
4
may, for example, be applied to the frameworks of any of the aforesaid patents or of various other frameworks.
As seen in
FIGS. 2 and 4
, the distance between front and rear hubs
14
and
16
respectively increases as the height of the framework decreases. Thus,
FIGS. 5 and 6
illustrate the framework at full height and a reduced height respectively.
FIG. 5
illustrates an alternative means of holding the framework at the full-height position, i.e., braces or bars
30
(only one shown) which extend between and are detachably attached to corresponding pairs of front and rear hubs
14
and
16
respectively. In order to lock the framework at a reduced-height position, the length of each bar
30
is suitably increased, such as by making the bar telescopingly or otherwise expandable, providing an extension piece, or by substituting a longer bar, illustrated at
31
, from the length, illustrated at
32
, for the full-height position to the length, illustrated at
34
, for the reduced-height position. It should be understood that, in accordance with the present invention, a single set of bars
30
and
31
may be sufficient to lock the framework in either of the expanded configurations. Furthermore, a set of more than two such bars may be provided to lock the framework alternately in more than two configurations. Such a system as illustrated in
FIGS. 5 and 6
may, for example, be applied to the frameworks of any of the aforesaid patents or of various other frameworks.
In accordance with another embodiment of the invention, referring to
FIGS. 11
to
17
, there is illustrated generally at
70
an alternative mag bar extruded from a rigid PVC or other suitable plastic material so that it may desirably have increased flexibility and be manufactured at reduced cost. Mag bar
70
has upper, central, and lower portions
72
,
74
, and
76
respectively which are hinged together with hinges
78
similarly as shown in FIG. 21 of U.S. Pat. No. 5,483,779 which patent is hereby incorporated herein by reference. The upper end of the upper portion
72
terminates in a reduced diameter portion
80
which is press-fit in a bore
82
in a light holder
84
, as seen in
FIG. 11
, which is suitably connected to the respective upper front hub
14
. Elongate hub attachment openings
86
are provided on the mag bar
70
for receiving mushroom-shaped heads
87
on the hubs
14
as well as on hubs
16
when the framework
10
is erected to full height and similar hub attachment openings
88
and
90
are provided in portions
72
and
74
respectively for receiving respective heads
87
when the framework is erected to a partially expanded configuration, similarly as described with reference to
FIGS. 1
to
4
. Alternatively, the heads
87
may have slots therein in which suitably shaped portions of the mag bars are snap-fitted.
However, mag bar
70
as described, while serving as a panel attachment means, may not be intended to serve also as a brace. At least one of a plurality of light arms
92
(one shown) may be adapted to also serve as a brace to hold the framework at the desired configuration. A light assembly
94
containing perhaps a halogen lamp is mounted to an end of the light arm
92
to slide within a yoke
96
of the holder member
84
and within a yoke
98
of a holder member
100
attached to the rear hub
16
during expanding and collapsing of the framework
10
. Suitable spaced enlarged portions or upsets
102
and
104
are provided on each of perhaps
2
of the arms
92
for locking the arm in position at the expanded positions respectively for full and reduced height configurations, thereby locking the framework
10
in the desired configuration. Thus, the yoke
96
is sized to receive the upsets
102
and
104
, as seen in FIG.
17
. After passage through the yoke, the respective upset drops downwardly to lock the framework at the desired height. There may of course be more than two upsets on a light arm to lock the framework at more than two heights respectively. Suitable fixtures other than lights may similarly be provided on arms which are similarly adapted to lock the framework at a desired height.
Instead of offsets, the light arm may alternatively be provided with spaced reduced-diameter depressions, illustrated at
106
, and the light holders
84
provided with upsets
108
on the lower portions of the yokes
96
. The depressions
106
“catch” on the upsets
108
respectively for locking the framework in position.
Referring to
FIG. 16
, the front face of each portion of the mag bar
70
has two side-by-side recesses in which may be contained a pair of flexible magnets
110
engageable by magnets
112
on panels
114
for connection thereof to the framework.
Referring to
FIG. 7
, there is illustrated generally at
40
a molded shipping case having a pair of rear wheels
42
for housing all of the components for the convertible pop-up display
10
including the framework, full-size panels, smaller-size panels, endcaps, lighting, and panel attachment bars. The case has a lid
43
hingedly connected to the body of the case by hinge
45
for opening the case for receiving and for stowing the components. The lid
43
has an upper platform
46
providing an upper surface
56
upon which papers, literature, or the like may be placed when the case is used as a podium. The case
40
also has upper and lower handles
49
on its rear side and a leveling bar
51
on its front side.
In accordance with the present invention, the shipping case
40
is convertible to a freestanding podium/counter unit by attaching a one-piece flexible fabric wrap or panel
44
around the sides or perimeter. The upper edge of the fabric covered wrap
44
abuts the platform
46
so that it is flush therewith for a pleasing appearance, as seen in FIG.
8
. For the purposes of this specification and the claims, the term “flush” is meant to refer to an abutting relationship between the platform
46
and panel
44
to form an unbroken view of the platform with the panel extending downwardly therefrom. The wrap
44
, which is composed of, for example, PVC, Lexan plastic, or other suitably flexible material, is also housed in the case
40
for shipment and stowage. A recess, illustrated at
48
, extends about the case
40
just below and adjacent the platform
46
. A continuous strip of hook-type fastener material
50
, commonly known as Velcro material, which may be self-adhesive, is adhesively attached therein. Rivets
59
, spaced along the length of the recess
48
, or other suitable mechanical attachment means may also attach the fastener material
50
to the case to further assure a positive permanent bond therebetween.
Decorative fabric material, illustrated at
52
, is provided along the upper edge portion of the wrap
44
on the inner as well as outer side thereof for attachment to Velcro material
50
and extends over the entirety of the outer side
47
thereof. A strip of hook-type fastener or Velcro material
60
is provided on the inner side of an end edge portion
61
of the wrap for attachment thereof to the cloth material on the other end edge portion
63
along the case rear. The wrap
44
is thus provided to cover and provide a pleasing appearance over the entire front, sides, and rear of the case
40
from flush with the platform
46
downwardly.
Alternatively, the wrap
44
may be covered with another suitable decorative graphics material. If such a material is not suitable for attachment of the Velcro strip
50
, then a separate strip of fabric or other suitable material may be placed along the upper inner edge of the wrap
44
for engagement with the Velcro strip.
The case upper surface
56
, which is suitably decoratively textured, acts as the counter top thereby eliminating the need for an actual separate top to be placed on the case. The single-piece wrap
44
is thus provided to easily and quickly convert the case into a freestanding podium/counter.
It should be understood that the invention can be embodied otherwise than as described herein without departing from the principles thereof For example, other frameworks, currently existing or developed in the future, may have means other than those described herein for holding them in an expanded position, and suitable alternative embodiments may be provided for converting the frameworks between configurations of at least two different erected heights. Such other embodiments are meant to come within the scope of the present invention as defined by the appended claims.
