Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to collapsible structures, and
in particular, to collapsible support frames that can be used to
support various items, and that can be folded and collapsed to
reduce the size of the frames.
[0003] 2. Description of the Prior Art
[0004] Collapsible objects have recently become popular with both
adults and children. Many of these collapsible objects have a
plurality of panels which may be twisted and folded to reduce the
overall size of the object to facilitate convenient storage and
use. Each panel is comprised of a fabric or material that is
supported by a resilient frame member, with the fabric or material
spanning a portion of, or entirely across, the area supported by
the frame member. The frame member supports the periphery of each
panel, and is capable of being twisted and folded to reduce the
size of each panel.
[0005] Examples of such collapsible objects are shown and described
in U.S. Pat. Nos. 5,467,794 (Zheng), 5,560,385 (Zheng) and
5,778,915 (Zheng) in the form of collapsible structures. These
structures are currently being enjoyed by many people in many
different applications. For example, these structures have been
provided in many different shapes and sizes for children's play
indoors and outdoors. Smaller versions of these structures have
been used as infant nurseries. Even smaller versions of these
structures have been used as dollhouses and action figure play
houses by toddlers and children. As another example, these
structures have been made into tents or outdoor structures that can
be used by adults and children for camping or other outdoor
purposes. These structures have also been used as beach cabanas.
Even animals can enjoy these structures. Some of these structures
have been made into shelters that can be used by pets, both indoors
and outdoors.
[0006] The wide-ranging uses for these collapsible structures can
be attributed to the performance, convenience and variety that
these structures provide. When fully expanded, these structures are
stable and can be used as a true shelter without the fear of
collapse. These structures are easily twisted and folded into a
compact configuration to allow the user to conveniently store the
structures. The light-weight nature of the materials used to make
these structures makes it convenient for them to be moved from one
location to another. These structures also provide much variety in
use and enjoyment. For example, a child can use a structure both
indoors and outdoors for different play purposes, and can use the
same structure for camping.
[0007] Another example of collapsible objects include collapsible
game and play structures, such as those illustrated in U.S. Pat.
Nos. 5,722,446 (Zheng) and 5,816,954 (Zheng). These structures
provide a multitude of game structures that can be enjoyed by
children and adults indoors and outdoors.
[0008] Yet another example of a collapsible object includes
collapsible sunshields, such as illustrated in U.S. Pat. No.
4,815,784 (Zheng). These sunshields have two interconnecting panels
that span the width of the windscreen.
[0009] In all of the above-mentioned collapsible structures, the
fabric or material is permanently attached (e.g., by stitching) to
the resilient frame members so that each panel is provided with a
fabric or material that cannot be changed unless the existing
fabric or material is cut or torn, which essentially destroys the
panel. As a result, these structures suffer from the drawback that
they lack variety in play and use, since they can only be used for
their originally intended applications.
[0010] However, there is a great benefit in providing users with
variety of play and use to increase amusement value, and the number
of applications to which a product can be used. Thus, there still
remains a need to provide collapsible objects and structures that
provide the user with increased variety of play, and which increase
the number of useful applications for these objects and
structures.
SUMMARY OF THE DISCLOSURE
[0011] In order to accomplish the objects of the present invention,
the collapsible structures according to the present invention have
one or more support frames, each having a foldable frame member
that has a folded and an unfolded orientation, with the frame
member defining a periphery for the support frame. Where more than
one support frame is provided, the support frames can be hingedly
coupled to each other. The frame member(s) can be used, for
example, to support panel pieces, objects and coverings, among
others. In some embodiments, one or more objects can be coupled to
and supported by the support frame(s). In other embodiments, a
covering may be placed over the support frame(s).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] The following detailed description is of the best presently
contemplated modes of carrying out the invention. This description
is not to be taken in a limiting sense, but is made merely for the
purpose of illustrating general principles of embodiments of the
invention. The scope of the invention is best defined by the
appended claims.
[0025] The present invention provides collapsible objects and
structures that have an underlying support frame structure. The
support frame structure has at least one resilient frame member
that can be folded and collapsed to reduce the size of the support
frame structure. The frame member(s) can be used, for example, to
support one or more removable panel pieces or objects, or to
support a removable covering. The principles of the present
invention can be used to provide collapsible support frame
structures for sunshields, dividers, partitions, play structures,
game structures, shelters, tents, cabanas, displays, cabinets, or
the like.
[0026] FIGS. 1A and 1B illustrate a collapsible support frame
structure 20 that embodies the underlying principles of the present
invention. Referring to FIG. 1A, the support frame structure 20 is
actually a singular support frame 20. The support frame 20 can
assume any configuration, such as polygonal (see FIGS. 3 and 5),
triangular (see FIG. 4), circular, oval, rectangular, square (as
shown in FIG. 1A), trapezoidal, or irregular. The support frame 20
has four side edges, a left side edge 22, a bottom side edge 24, a
right side edge 26, and a top side edge 28. Referring also to FIG.
1B, the support frame 20 has a continuous frame retaining sleeve 30
provided along and traversing the four edges of its four sides. A
continuous frame member 32 is retained or held within the frame
retaining sleeve 30 to support the support frame 20.
[0027] The continuous frame member 32 may be provided as one
continuous loop, or may be a strip of material connected at both
ends to form a continuous loop. The frame member 32 is preferably
formed of flexible coilable steel, although other materials such as
plastics may also be used. The frame member 32 should be made of a
material which is relatively strong and yet is flexible to a
sufficient degree to allow it to be coiled. Thus, the frame member
32 is capable of assuming two positions, an open or expanded
position such as shown in FIG. 1A, or a folded position in which
the frame member 32 is collapsed into a size which is much smaller
than its open position (see FIG. 2E).
[0028] The frame member 32 may be merely retained within the frame
retaining sleeve 30 without being connected thereto. Alternatively,
the frame retaining sleeve 30 may be mechanically fastened,
stitched, fused, or glued to the frame member 32 to retain the
frame member 32 in position.
[0029] Optional fabric corner pieces 34 can be attached to and held
taut at the corners of the support frame 20. The term fabric is to
be given its broadest meaning and should be made from strong,
lightweight materials and may include woven fabrics, cloth, sheet
fabrics, straps, nylon, string, rope or even films. These corner
pieces 34 function to provide the support frame 20 with a
pre-defined configuration, especially if the support frame 20 is
large in size. For example, if corner pieces 34 were omitted from
the support frame 20 and the support frame 20 was large, the
resilient nature of the frame member 32 may cause the support frame
20 to coil into an undefined shape. Therefore, providing four
corner pieces 34 as shown in FIG. 1A would define a generally
square or rectangular support frame 20, providing three corner
pieces 34 would define a generally three-sided support frame (see
FIG. 4), and so on, as will be illustrated in greater detail in
connection with FIGS. 3-5 below.
[0030] As best illustrated in FIG. 1B, the frame retaining sleeve
30 may be attached to each fabric corner piece 34 by applying a
stitching 36 that extends along a portion of the side edges 22, 24,
26, 28. The stitching 36 is also applied to enclose the frame
retaining sleeve 30 at the other portions of the side edges 22, 24,
26, 28 where no corner pieces 34 or other fabric are attached
thereto.
[0031] A removable panel piece 38 may be supported from the support
frame 20. The panel piece 38 can be of any size (i.e., it can even
be large enough to cover the entire support frame 20, as shown by
panel piece 38a in FIG. 1C) and can take the form of a fabric piece
having a message, sign, indicia, illustration, amusement feature
(e.g., netting or basket or bulls-eye target, etc.), game feature,
or anything else provided thereon. For example, the panel piece 38
is illustrated in its simplest form in FIG. 1A as having an indicia
or illustration 40 provided or printed on one or both surfaces. The
panel piece 38 can have any shape or size, and is provided with a
plurality of attachment mechanisms 42 (such as straps, strings,
ropes, ties, hooks, opposing Velcro.TM. pads, etc.) that couple the
panel piece 38 to the sides 22, 24, 26, 28 of the support frame 20,
yet allows the panel piece 38 to be detached therefrom when
desired. For example, FIG. 1A shows the use of strings 42 that have
one end 44 permanently attached (e.g., by stitching) to the panel
piece 38 and an opposing free end 46 that can be tied to the
support frame 20. As another example, Velcro.TM. pads or straps 42a
can be permanently attached (e.g., by stitching) to the panel piece
38a in FIG. 1C for coupling to the support frame 20. Although
certain attachment mechanisms 42 are illustrated herein, it is
possible to use any known and conventional attachment mechanism
that is adapted for use with the specific size, shape and other
requirements of the panel piece 38.
[0032] Thus, the user can conveniently replace the panel piece 38
shown in FIG. 1A with a different panel piece that has a different
display, or game, or feature, by simply untying or detaching the
attachment mechanisms 42 from the support frame 20, removing the
panel piece 38, and securing a different panel piece to the support
frame 20. This allows the same support frame 20 to be used for
supporting different panel pieces 38. In addition, even though only
one panel piece 38 is illustrated in FIG. 1A, it is possible for
the support frame 20 to support a plurality of panel pieces 38, as
illustrated in the other embodiments below.
[0033] The support frame 20 can also be folded and collapsed into a
compact configuration for storage, as illustrated in FIGS. 2A-2E.
FIG. 2A shows the support frame 20 without the panel piece 38,
ready to be folded. First, as shown in FIG. 2B, two opposite sides
of the support frame 20 are folded in opposite directions (see
arrows 50 and 52) cause the support frame 20 to be coiled and
collapsed (see FIG. 2C). As shown in FIG. 2D, the collapsing is
continued so that the initial size of the support frame 20 is
reduced. Finally, the support frame 20 is collapsed on itself to
provide for a small essentially compact configuration having a
plurality of concentric frame members 32 so that the collapsed
support frame 20 has a size which is a fraction of the size of the
initial support frame 20, as shown in FIG. 2E. Thus, the support
frame 20 can be folded and stored very quickly using the steps
illustrated in FIGS. 2A-2E.
[0034] To re-open the support frame 20 to its expanded
configuration, the collapsed support frame 20 is unfolded. The
memory (i.e., spring-load) of the frame member 32 will cause the
frame member 32 to uncoil on its own and quickly expand the support
frame 20 to the expanded configuration shown in FIG. 1A. The
above-described methods and principles for folding and collapsing a
support frame 20, and for re-opening the support frame 20 to deploy
it for use, can be applied to all the embodiments illustrated
hereinbelow.
[0035] FIG. 3 illustrates a singular support frame 20a that is the
same as support frame 20 of FIG. 1A, except that support frame 20a
has five sides defined by the five corner pieces 34a. Similarly,
FIG. 4 illustrates a singular support frame 20b that is the same as
support frame 20 of FIG. 1A, except that support frame 20b has
three sides defined by the three corner pieces 34b. Note that one
of the corner pieces 54 is provided in the form of a strap that is
held taut between the two adjacent sides 22b and 24b. Similarly,
FIG. 5 illustrates a singular support frame 20c that is the same as
support frame 20 of FIG. 1A, except that support frame 20c has six
sides defined by the six corner pieces 34c. Panel pieces 38 are not
shown in FIGS. 3-5, 9, 10, 12 and 14-16 to simplify those
illustrations, but it is intended that any of the support frames in
these FIGS. can be used to support one or more panel pieces 38.
[0036] In the support frames 20, 20a, 20b and 20c described above,
the panel piece 38 can be supported from the sides of the support
frame itself. However, to increase the number of panel pieces 38
that can be supported by a support frame, and to allow for
variations in how these panel pieces 38 can be arranged in a
support frame, it is possible to provide one or more support
pieces, such as 60 in FIG. 6A. Referring to FIG. 6A, a singular
support frame 20d is provided that is the same as support frame 20
of FIG. 1A, except that the corner pieces 34 have been omitted, and
instead, a cross-shaped support piece 60 having four legs is
provided. Each leg of the support piece 60 has an end 62 that is
attached (e.g., in a permanent manner by stitching, or in a
detachable manner by Velcro.TM. pads, straps, ties, hooks or
similar mechanisms) to a separate side 22d, 24d, 26d and 28d of the
support frame 20d. The support piece 60 and its legs also help to
define the shape of the support frame 20d, since the four separate
ends 62 each define one side of the support frame 20d. The support
piece 60 can be made of a durable fabric, wire, strap, rubber, or
soft plastic material. For example, the support piece 60a in FIG.
6B can be either a wire, strap, rubber piece or soft plastic piece.
The support piece 60 or 60a can be used alone, or together with the
support frame 20d, to support one or more panel pieces or
items.
[0037] This is illustrated in greater detail in FIG. 7, where the
singular support frame 20e has an irregular shape that is defined
by the various ends 66 of the support piece 68. The support frame
20e is essentially the same as support frame 20d of FIG. 6, except
that the support piece 68 has an irregular shape having six
separate legs 70, each having different lengths to cause the
support frame 20e to assume the irregular configuration shown in
FIG. 7. For example, leg 70a is longer than leg 70b, which causes
the same "side" 26e to be curved in several locations. A large
variety of items can be supported by the support frame 20e and the
support piece 68. For example, a picture frame 72 can be supported
by attaching straps, strings or ties 76 to the picture frame 72 and
the sides 26e and 28e of support frame 20e, and legs 70a and 70f of
support piece 68. A rotating ball 74 can be supported by a shaft 78
that has opposing ends attached to legs 70a and 70b. An arrangement
of rotating balls 80 can be supported by shafts, strings or ties 82
that have opposing ends attached to sides 24e and 26e and to legs
70b and 70c. A rotatable tin can 84 or other object can be
supported by a shaft or string 86 that has opposing ends attached
to leg 70d and side 22e. Thus, as shown in FIG. 7, some items (such
as picture frame 72, the arrangement of balls 80, and tin can 84)
are supported by both a side of the support frame 20e and a leg of
the support piece 68, while other items (such as ball 74) is
supported by two or more adjacent legs 70 of the support piece 68
without support from the support frame 20e.
[0038] The support frame structures of the present invention can
have two or more support frames. Referring to FIG. 8A, the support
frame structure 100 has two support frames 102 and 104, each of
which can have the same construction as support frame 20 of FIG.
1A. Each support frame 102, 104 has four sides, and are hingedly
coupled together along their top sides 106 and 108, respectively.
This hinged coupling can be accomplished in a permanent manner by
stitching the frame retaining sleeves of the support frames 102,
104 along the top sides 106, 108, or in a detachable manner by
using a detachable attachment mechanism such as Velcro.TM. pads,
ties, straps, hooks and similar mechanisms. When coupled in the
manner shown in FIG. 8, the support frames 102, 104 together form
an inverted V-shape structure with each support frame 102, 104
angled with respect to the ground and each other, and with a bottom
side 107, 109 of each support frame 102, 104, respectively, adapted
to rest on the ground or surface. Each support frame 102, 104 can
support one or more panel pieces 110, 112, respectively, that can
be coupled to the support frames 102, 104 according to the
techniques described above. In this embodiment, the panel piece 110
can display a "sale" sign, and the other panel piece 112 can
display another message.
[0039] The support frame structure 100 of FIG. 8A can be folded and
collapsed by first folding one support frame 102 or 104 on to the
other support frame 104 or 102 about the hinged coupling of the top
sides 106, 108 to create a stack of two support frames 102, 104.
This stack of two support frames 102, 104 can then be twisted and
folded according to the method of FIGS. 2A-2E.
[0040] FIG. 8B illustrates a modification that can be made to the
structure 100 of FIG. 8A. In FIG. 8B, the structure 100a is
essentially the same as structure 100, except that each support
frame 102a, 104a is provided with a cross-shaped support piece 111
and 113, respectively, similar to support piece 60 in FIG. 6A.
Objects and panel pieces can be supported from these support pieces
111, 113 and the support frames 102a, 104a.
[0041] FIG. 9 illustrates a four-sided support frame structure 120
having four support frames 122, 124, 126 and 128, each of which can
have the same construction as support frame 20 of FIG. 1A but
having a different shape. Each support frame 122, 124, 126, 128 has
three sides, and the left side 130 of each support frame 122, 124,
126, 128 is hingedly coupled to a right side 132 of an adjacent
support frame to form an enclosed space inside the four support
frames 122, 124, 126, 128. These hinged couplings can also be
accomplished in a permanent manner or in a detachable manner by
using the mechanisms described above. Three corner pieces (which
can be fabric pieces 134 or straps 136) are provided at the three
corners of each support frame 122, 124, 126, 128. Each support
frame 122, 124, 126, 128 can support one or more panel pieces (not
shown) that can be coupled to the support frames 122, 124, 126, 128
according to the techniques described above. For example, a user
can provide a panel piece that completely covers a frame to act as
a side wall. In this manner, if each support frame 122, 124, 126,
128 is provided with a panel piece that covers the frame, then the
user can essentially provide a collapsible shelter having four
different panel pieces. These panel pieces can be removed and
replaced by other panel pieces having different designs or patterns
or amusement features to vary the appearance of the collapsible
shelter.
[0042] The support frame structure 120 of FIG. 9 can be folded and
collapsed by first pushing support frames 122 and 124 against
support frames 128 and 126, respectively, about the hinged coupling
of the left and right sides 130, 132. The combined support frames
122, 128 can then be folded on to the combined support frames 124,
126 about the hinged couplings to create a stack of four support
frames 122, 128, 126, 124, in this order. This stack of four
support frames can then be twisted and folded according to the
method of FIGS. 2A-2E.
[0043] FIG. 10 illustrates a support frame structure 120a that is
essentially the same as support frame 120 of FIG. 9, except that
the top corner pieces 134a are attached in a taut manner between
adjacent support frames 122a, 124a, 126a, 128a (also known as
"external corner pieces"). Specifically, the top corner pieces that
are normally provided within the confines of a corner of a specific
support frame 122a, 124a, 126a, 128a (also known as "internal
corner pieces") are now omitted, and replaced by external corner
pieces 134a that are attached to two adjacent support frames 122a,
124a, 126a, 128a in the space between these adjacent support
frames. The external corner pieces 134a provide the benefit of
keeping the interior of the support frames 122a, 124a, 126a, 128a
open and clear for use in supporting objects or other items, since
the internal corner pieces will invariably intrude into the space
defined by the interior of the support frames 122a, 124a, 126a,
128a. Both the interior corner pieces and the external corner
pieces perform the same function of defining the shape of the
support frames 122a, 124a, 126a, 128a.
[0044] FIG. 11 illustrates a four-sided support frame structure 140
having four support frames 142, 144, 146 and 148, each of which can
have the same construction as support frame 20 of FIG. 1A. Each
support frame 142, 144, 146, 148 has four sides, and the left side
150 of each support frame 142, 144, 146, 148 is hingedly coupled to
a right side 152 of an adjacent support frame to form an enclosed
space inside the four support frames 142, 144, 146, 148. These
hinged couplings can also be accomplished in a permanent manner or
in a detachable manner by using the mechanisms described above.
Four corner pieces (e.g., straps 156) are provided at the four
corners of each support frame 142, 144, 146, 148. One support frame
142 has longer left and right sides 150, 152, so that a fabric
piece 158 can be attached (e.g., by stitching) to the top side 160
of support frame 142. A basket or netting 162 can be attached to
fabric piece 158 so that support frame 142 can be used to support a
backboard. The support frame 142 can support one or more other
panel pieces that can be coupled to the support frame 142 according
to the techniques described above. Another support frame 144 can
support a panel piece 164 that includes a "bulls-eye" target.
Although not shown, the other support frames 146 and 148 can
support one or more panel pieces that can be coupled to the support
frames 146, 148 according to the techniques described above. Thus,
the structure 140 allows the user to change panel pieces for each
support frame 142, 144, 146, 148 to increase the variety of
play.
[0045] The support frame structures of the present invention can
also be used to support different coverings. Referring to FIGS. 12
and 13, a support frame structure 180 is provided having seven
support frames 182, 184, 186, 188, 190, 192 and 194, each of which
can be the same as support frame 20 of FIG. 1A. Each of the six
outer support frames 182, 184, 186, 188, 190, 192 has four sides,
and the left side 196 of each of these support frames 182, 184,
186, 188, 190, 192 is hingedly coupled to a right side 198 of an
adjacent support frame to form an enclosed space inside the six
outer support frames 182, 184, 186, 188, 190, 192. The inner
support frame 194 is provided inside the enclosed space, with one
side 200 of the inner support frame 194 hingedly coupled to the
hinged coupling between support frames 190 and 192, and another
side 202 of the inner support frame 194 hingedly coupled to the
hinged coupling between support frames 184 and 186. These hinged
couplings can also be accomplished in a permanent manner or in a
detachable manner by using the mechanisms described above. Support
frame 194 is positioned to provide additional stability to the
structure 180.
[0046] The structure 180 can be folded and collapsed by first
pushing support frames 182 and 184 against support frames 192 and
194, respectively, and by pushing support frames 186 and 188
against support frames 194 and 190, respectively, about the hinged
couplings of the left and right sides 196, 198 of the respective
support frames. The combined support frames 182, 192 can then be
folded on to the combined support frames 184, 194, and the combined
support frames 188, 190 can then be folded on to the combined
support frames 186, 194, about the hinged couplings, to create a
stack of seven support frames 192, 182, 184, 194, 186, 188, 190, in
this order. This stack of seven support frames can then be twisted
and folded according to the method of FIGS. 2A-2E.
[0047] Referring now to FIG. 13, a covering 208 can be draped or
otherwise placed over the support frame structure 180. The covering
208 can be sized and shaped to correspond to the size and shape of
the support frame structure 180, and can be made from a fabric,
cardboard, meshed, or other material. In this regard, the covering
208 also has four sides to create a rectangular shape, and can
include a top or roof cover 209. The bottom of the covering 208 can
be open so that the covering 208 can be draped over the support
frame structure 180 in the direction of arrow 210 as shown in FIG.
13. Each covering 208 can be provided with different designs,
patterns, indicia, games or amusement. For example, the covering
208 shown in FIG. 13 can be decorated to look like a school bus,
including an opening 212 cut from a side of the covering 208 to
allow ingress and egress to and from the interior of the structure
180, and an opening 214 cut from the front side to form a front
windshield. Thus, the user can replace this covering 208 with
another covering bearing a different theme, pattern, design, game
or amusement, so that the support frame structure 180 can be used
to support a wide variety of coverings, thereby increasing the
utility of the support frame structure 180.
[0048] FIG. 14 illustrates a four-sided support frame structure 220
having four support frames 222, 224, 226 and 228, each of which can
have the same construction as support frame 20 of FIG. 1A, except
that each support frame 222, 224, 226, 228 is generally circular in
configuration, with each support frame 222, 224, 226, 228 hingedly
coupled to an adjacent support frame at their circumferences to
form an enclosed space inside the four support frames. These hinged
couplings can also be accomplished in a permanent manner or in a
detachable manner by using the mechanisms described above. Since
the shape of each support frame 222, 224, 226, 228 is generally
circular, no corner pieces (such as 34) are needed. The structure
220 can be folded and collapsed using the same technique for the
support frame structures 120, 120a and 140 in FIGS. 9-11.
[0049] FIG. 15 illustrates a support frame structure 240 having two
support frames 242 and 244, each of which can have the same
construction as support frame 20 of FIG. 1A, except that each
support frame 242, 244 has a different shape. The support frames
242 and 244 are hingedly coupled along the right side 246 of
support frame 242 and the left side 248 of support frame 244. This
hinged coupling can also be accomplished in a permanent manner or
in a detachable manner by using the mechanisms described above. The
shapes of the support frames 242, 244 are defined by the various
corner pieces. For example, each support frame 242, 244 has two
internal corner pieces 250 attached within the respective support
frame 242 or 244. In addition, two external corner pieces 252 are
attached to the outside of the other corners of the support frames
242, 244, such that these external corner pieces 252 actually
attach and couple between the two support frames 242, 244 in a
manner similar to external corner pieces 134a in FIG. 10. The
structure 240 can be folded and collapsed using the same technique
for the support frame structure 100 in FIG. 8.
[0050] FIGS. 16 and 17 illustrate another embodiment of a support
frame structure 260 according to the present invention. The support
frame structure 260 has two support frames 262 and 264, each of
which can be the same as support frame 20 of FIG. 1A. The support
frames 262, 264 cross or intersect at an angle, and can be provided
in this intersecting configuration by providing one support frame
(e.g., 264) with a slightly smaller width so that it can be fitted
inside the confines of the other support frame 262, and then
coupling the two support frames 262, 264 at their two crossing or
intersection points 266 and 268. One intersection point 266 is
shown in greater detail in FIG. 17 (the other intersection 268
being the same), where a string or tie 270 can be used to tie the
support frames 262, 264 together in a manner that allows them to
pivot with respect to each other at these intersection points 266,
268. Thus, to deploy the structure 260, the support frames 262, 264
can be pivoted about the intersection points 266, 268 so that the
bottom side 272 and 274 of each support frame 262 and 264,
respectively, can be rested on a floor or surface (see FIG. 16).
When in this configuration, the structure 260 is essentially
self-supporting. As an alternative, a tie or strap 271 can have
opposing ends secured (either permanently or detachably) to the
support frames 262, 264 above an intersection point 266 or 268 to
limit the extent to which the support frames 262, 264 can pivot.
Corner pieces or straps 276 can be provided for each support frame
262, 264. To fold and collapse the structure 260, the support
frames 262, 264 can be pivoted so that they are generally parallel
to each other to form a stack of two support frames 262, 264. This
stack of two support frames can then be twisted and folded
according to the method of FIGS. 2A-2E.
[0051] Although not expressly shown in FIGS. 8-16, the structures
shown in FIGS. 8-16 can also have support pieces like the support
pieces 60 and 68 shown in FIGS. 6 and 7.
[0052] Thus, the present invention provides collapsible support
frame structures that allow a variety of games, designs, indicia,
messages, etc., to be supported thereon, and to be removed and
replaced by others. This increases the utility and use of these
collapsible support frame structures since they can be used to
support many different games, designs, indicia, messages, etc., and
also provides the user with increased variety in play and
amusement.
[0053] While the description above refers to particular embodiments
of the present invention, it will be understood that many
modifications may be made without departing from the spirit
thereof. The accompanying claims are intended to cover such
modifications as would fall within the true scope and spirit of the
present invention. For example, although the panel pieces 38,
objects and other items have been described as being removable, it
is also possible to attach panel pieces 38, objects and other items
to the support frames in a permanent, non-removable manner.
