Modular display frame structure
Abstract
A modular frame assembly to which panels are attachable to
create partitions for dividing a large open area into cubicles,
alcoves and other sub-chambers defining an interior environment.
The assembly is composed of at least one I-shaped center component
having upper and lower pairs of outstretched arms which cooperate
with a pair of end components, each formed by a U-shaped element
whose extremities have L-shaped pieces swiveled thereon which in
the flat state of the end component form a complementary U
completing an O-form. When the pieces of the end components are
rotated to assume positions at right angles to the U-shaped
elements, they define horizontally-extending legs which are
connectable to the arms of the center component to create a
free-standing frame structure which may be linked to like
structures.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to modular frame structures, and
more particularly to a structural assembly composed of a set of
modular components which all lie flat when disassembled and which
define a free-standing display frmae when erected.
Flexibility, and versatility are the hallmarks of modern interior
architectural design, for when an interior space is intended for
diversified purposes, one must be able to readily transform this
space from an existing configuration to another form adapted to a
new use. It is for this reason that buildings designed to present
trade shows, exhibitions and other types of displays often make use
of detachable interior walls that may be set up in various patterns
to divide an available space into temporary sub-chambers or
compartments which meet the needs of the moment.
In public buildings, exhibition halls, department stores and
banking establishments having large unbroken floor areas, it is
often necessary, in order to make a special presentation, to
segregate a particular zone of the available space. One could, of
course, by means of temporary partitions, erect a special enclosure
for this purpose, but this involves relatively expensive carpentry
and may be disruptive to existing activity being carried out on the
floor.
Attempts have heretofore been made to solve this problem by
providing structural modules or building blocks capable of being
interconnected to define various structural forms. But such
modules, even though relatively heavy and cumbersome, have been
lacking both in strength and flexibility, so that only a limited
number of forms could be created.
Moreover, in evaluating the usefulness of a modular structure, one
must not only take into account the ability of the structure to
create a variety of walls and partitions, but it is also important
to consider storage and transportation factors. If the modular
structure, when disassembled, is bulky and has high space
requirements, this adds substantially to the cost of storing the
structure when not in use and to the expense of transporting the
structure to an exhibition hall or other site. Because existing
modular structures do not break down into flat, compact pieces,
they cannot be stored and transported at low cost.
SUMMARY OF THE INVENTION
In view of the foregoing it is the main object of this invention to
provide a modular frame structure to which panels are readily
attachable to create free-standing partitions for dividing a large
exhibition area into cubicles, alcoves and other sub-chambers.
More particularly, it is an object of this invention to provide a
basic modular frame assembly composed of a set of modular
components which all lie flat when disassembled to facilitate
storage and transportation thereof.
A significant feature of this invention resides in the fact that
the basic frame structure in combination with attached panels
creates a cubicle formed by a main wall and end walls extending at
right angles thereto, the end walls extending in the same or
opposite directions, depending on how the components are
assembled.
Also, an object of the invention is to provide a set of modular
components which together form a basic modular frame structure, the
components all being formed of light-weight, high-strength tubing
whereby the components may be handled and carried without
difficulty.
An important advantage of the invention is that it lends itself to
very rapid assembly without the need for special tools or
equipment, and that the resultant frame structure even though
movable and not in any way anchored to the floor, the ceiling or
the permanent walls of the area in which it is installed, is
nevertheless stable, safe and pleasing in appearance.
Yet another object of the invention is to provide a coupler adapted
to attach panels to the structural frame and also suitable for
interlinking two or more structural frames in end-to-end or in
vertically-stacked relation to produce a large variety of
structural patterns.
Briefly stated, these objects are attained in a basic modular frame
structure composed of at least one I-shaped center component having
upper and lower pairs of outstretched arms which cooperate with a
pair of end components each formed by a U-shaped element whose
extremities have L-shaped pieces pivoted thereto which in the flat
state have a complementary U-shaped form. When the pieces of the
end components are rotated to assume positions at right angles to
the U-shaped elements, the define legs which are connectable to the
arms of the center component to create a free-standing frame
structure to which wall panels may be attached.

DESCRIPTION OF THE INVENTION
Referring now to FIG. 1, a basic modular structural frame assembly
in accordance with the invention is shown, the assembly being
composed of a center component, generally designated as CC and a
pair of end components EC.sub.1 and EC.sub.2. All of these
components are preferably fabricated of metal piping such as
aluminum or stainless steel, although in practice, one may also use
synthetic plastic tubing of high strength.
Center component CC has an I formation constituted by a center post
10 having a pair of lateral arms 11 and 12 extending from opposite
sides of the upper end thereof and a like pair of arms 13 and 14
extending from the lower end thereof. Thus the center component is
provided with upper and lower pairs of outstretched arms.
Projecting axially from these arms are connector pins 11a, 12a, 13a
and 14a, respectively. All elements of the center component lie in
the same plane, hence this component may be laid flat for purposes
of storage and transportation. Center component CC is raised when
in use so that center post 10 is then vertical.
End components EC.sub.1 and EC.sub.2, when the structure is
disassembled, also lie flat to assume a generally rectangular form
as shown in FIG. 1. Each end component is constituted by a U-shaped
element 15 whose upper and lower arms have L-shaped pieces 16 and
17, swiveled thereto which in the flat state form a complementary U
and complete an O-form. Pieces 16 and 17 may be rotated relative to
the branches of the U-shaped element 15. As shown in FIG. 2, in
regard to piece 16, the pivotal connection to element 15 may be
effected by plugs 15A and 16A forced into the end of a branch of
tubular element 15 and the end of piece 16 respectively, the plugs
being joined by a pivot pin 18.
When in the flat state, the L-shaped pieces 16 and 17 of the end
components together assume a U-formation which complements the
U-form of element 15, but when the L-shaped pieces 16 and 17 are
rotated to assume positions at right angles to element 15, as shown
in FIG. 3, they then define two pairs of legs which are joinable to
the arms 11 to 14 of the center component. Connector pins 11A and
14A of the center component arms enter into the hollow legs of the
end components EC.sub.1 and EC.sub.2 with a snug fit, or are
latched therein by suitable retractable detent means (not
shown).
Thus, when end components EC.sub.1 and EC.sub.2 are joined to
center component CC in the manner shown in FIG. 4, the resultant
frame structure is free-standing in that the end components act as
right-angle brackets with respect to the center component. It then
becomes possible to attach panels 19 and 20 to the frame structure
to form a main wall serving as a partition and as a display surface
onto which posters and other display objects may be applied.
Panels 19 and 20 are of double-walled construction, each panel as
shown in FIG. 5 having parallel walls 19A and 19B and a spacer 21
sandwiched therebetween, the upper and lower ends of the spacer
falling short of the wall to define sockets for accommmodating the
horizontally-extending parallel pipes of the frame structure. The
upper socket is deeper than the lower socket so that the panel may
be elevated to align the lower socket with the lower pipe. Thus, to
install the double-walled panels, it is only necessary to insert
them between the parallel pipes of the structure. Similar
double-walled panels may be installed in the end portions of the
frame structure to provide end walls closing in the alcover formed
thereby.
In the arrangement shown in FIG. 4, the frame structure is
assembled so that the right angle end portions thereof both extend
in the same direction. But a more stable, free-standing arrangement
may be provided by assembling the center component with the end
components so that the resultant right angle portions extend in
opposite directions as illustrated in FIG. 6.
In FIG. 6 it will be seen that two panels 22 and 23 are attached to
the frame structure by means of double-ended couplers 24, two of
the couplers serving to connect the upper edge of each panel to the
upper bar of the frame and two to the lower bar.
As shown in FIGS. 9 and 10, each double-ended coupler 24 is
composed of a pair of complementary jaws 24A and 24B. Each jaw is
provided with a pair of like arcuate recesses such that when the
jaws are joined together by means of a removable bolt 25, the
recesses define a pair of mouths 26 and 27 which are dimensioned to
receive and clamp by cylindrical pipes of the frame, such as pipe
11 shown in FIGS. 9 and 10. In order to join a pipe to a panel, an
elastomeric insert plug 28 is provided which fits into and is
gripped by a mouth of the coupler, the plug having a slot 29 to
accommodate the edge of the panel.
Thus coupler 24, without the plug, is adapted to join two frame
pipes together, and thereby to interconnect adjacent frame
structures, and with the plug inserted therein, to join a panel to
a pipe. The entire assembly package is constituted by the frame
components, the panels and the couplers all of which may be housed
in a shallow box suitable for shipment.
As illustrated in FIG. 7, instead of having separate flat panels to
define the main and side walls of the assembly, one may use curved
panels 30 and 31 which are held to the bars of the frame structure
by couplers 24 which are so placed as to join all sides of the
curved panels to the frame. In practice instead of panels of wood
or metal to form the walls of the partition, one may use canvas or
other textile material for this purpose.
FIG. 8 shows one of the many design possibilities inherent in a
frame structure in accordance with the invention. Not only is each
of the basic modules capable of being set up so that the end
components lie in the same or in opposite directions, but it is
also possible to interconnect the modules by means of couplers 24
so that the modules are stacked one above the other to increase the
height of the partition. The modules may also be interconnected in
end-to-end relation to increase the length of the partition.
Thus module M.sub.1 in FIG. 8 is connected in end-to-end relation
to module M.sub.2, and above these modules and attached thereto are
modules M.sub.3 and M.sub.4. While in FIG. 8, the panels attached
to the frames are all curved, in practice the panel arrangement may
be planar, as in FIG. 4. It will be appreciated that because the
basic module may be erected with its end components in the same or
in opposite directions, because the end components of adjacent
modules may be joined together in face-to-face relation, in
opposition or in angular relationship, and because the modules may
be interconnected vertically or horizontally, the range of possible
structural configurations is very broad, and one may create
interior environments which are of relatively simple design or of
great complexity.
In the modules previously described, the end components EC.sub.1
and EC.sub.2 are united to a single center component CC. In order
to produce longer structural frames, one may provide two or more
serially-connected center components such as center components
CC.sub.1 and CC.sub.2 shown in FIG. 11.
While there has been shown and described preferred embodiments in
accordance with the invention, it will be appreciated that many
changes and modifications may be made therein without, however,
departing from the essential spirit thereof.
For example one may use coupler 24 not merely to interconnect
adjoining pipes or to attach panels to the pipes but also to mount
light fixtures and other appliances on the pipes. For this purpose
the light fixture, loud speaker or other appliance is secured to
the coupler by means of a suitable bracket having a bar component
which is clamped between one pair of jaws of the coupler, the other
pair of jaws being clamped on the frame pipe. The light fixture
itself may be swiveled on the bracket by means of a gimbal so that
one may orient the light fixture as desired.
