Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable partition and more
particularly to a portable partition for a table which when
unfolded will create a cluster of carrels.
2. Description of the Prior Art
It is well known in the prior art to use partitions to break-up a
large table area into several individual compartments or carrels.
It is also well known to make available to each compartment
separate audio and visual communication connections. However, the
prior art carrel systems were of a permanent nature having fixed or
permanently positioned walls and were not easily dismantled or
removeable to another location. It is toward elimination of these
problems that the present invention is directed.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide a portable,
collapsible partition for a flat table which when unfolded will
establish a cluster of individual carrels.
Another object of the present invention is to provide a separator
which will align each of the panels of the partition and which will
provide access to communication media in each of the carrels.
Still another object of the present invention is to provide a low
cost partition which will transform a table surface into a cluster
of individual carrels.
Yet another object of the present invention is to provide a
partition which is inexpensive to manufacture and lightweight.
A further object of the present invention is to provide a partition
which will allow for maximum utility of limited available
space.
A still further object of the present invention is to readily
convert open table areas into individual carrels for use in
independent educational instruction or study.
Generally the foregoing and other objects are achieved by a
portable collapsible partition for a table which consists of
different wall segments that are hinged to each other and can be
positioned so as to form a cluster of carrels. A separator is
designed to align the partitions and also makes communication media
available in each carrel.
Still further objects and advantages of the invention will in part
be obvious and will in part be apparent from the specifications.
The invention accordingly consists in the features of construction
combinations of elements and arrangement of parts which will be
exemplified in the portable, collapsible partition hereinafter
described in the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With specific reference to the form of the present invention
illustrated in the drawings and referring particularly to FIGS. 1
and 2, a portable collapsible partition is indicated generally by
the reference numeral 10. The portable collapsible partition is
depicted in its open position and is shown resting upon the top
surface 14 of a table 12. The portable collapsible partition 10 in
its unfolded state serves to divide the top surface 14 of the table
12 into several individual areas 16a, b, c, d, e and f.
While the partition shown in the drawings and hereinafter described
consists of seven panels, it is to be understood that the present
invention is not so limited. The partition may consist of any
number of panels sufficient to create a cluster of carrels
compatable with a particular size and shape table surface.
As illustrated, the partition is composed of seven panels or wall
segments 20, 22, 24, 26, 28, 30 and 32. The panels can be made of
any lightweight, rigid material such as plastic, wood or
fiberboard. In order to provide a collapsible partition, the
various panels are hinged together and the manner of hinging will
hereinafter be more fully described.
As may be seen in FIG. 4 a first hinge 21 enables panels 20 and 22
to be connected together and rotated relative to each other. The
hinge 21 may extend the length of the side 20a of panel 20 and can
be a piano hinge or a hinge of a similar type, as can any of the
other hinges used in the present invention. The hinge 21 is set
back from the edge 22a of the panel 22 so that when the panel 20 is
rotated away from the panel 22 the edge 20b of the panel 20 will
come in contact with the edge 22a to keep the panel 20
substantially perpendicular to the panel 22. Similarly a second
hinge 23 along edge 24a of the panel 24 enables panels 22 and 24 to
be rotated relative to each other. The hinge 23 is set back from
the edge 22b so that when the panel 24 is rotated away from the
panel 22 the edge 24b will come in contact with the edge 22b to
keep the panel 24 substantially perpendicular to the panel 22.
A third hinge 25 is provided along the edges 24c and 26a of panels
24 and 26 respectively which allows the panel 24 to rotate away
from the panel 26.
A fourth hinge 27 is provided along the edges 26b and 28a of panels
26 and 28 respectively to allow panel 28 to rotate away from panel
26.
Provided along edge 28b is a fifth hinge 29 which will allow the
panel 28 to be rotated relative to the panel 30. The hinge 29 is
mounted away from the edge 30a so that the end 28c will contact the
edge area 30a when the panel 28 is rotated away from the panel 30
to keep the panel 28 substantially perpendicular to the panel
30.
A last hinge 31 is provided along the edge 32a of panel 32 and set
back from the edge 30b so that when the panel 32 is rotated away
from the panel 30 edge 32c will contact 30b to keep the panels
substantially perpendicular.
When the partition is fully unfolded, as shown in FIG. 5, panels
22, 26 and 30 are in alignment and panels 20 and 24 are in
alignment and perpendicular to panels 22 and 26 and panels 28 and
32 are in alignment and perpendicular to panels 26 and 30.
In order to further align the panels of the unfolded partition and
to prevent them from moving relative to each other, separators 40
and 42 are placed over the two junctions formed by the unfolded
panels. As shown in FIGS. 6 and 7 the separators have a
platform-like portion 44 and a locking portion 46. The locking
portion 46 has essentially four legs 46a, b, c and d which are
spaced from one another so that slots 48a, b, c and d are formed
therebetween. The slots are all at right angles to one another and
are substantially the same width as the thickness of the panels so
that when the separator is placed over the panels the panels are
fixedly held in place perpendicular to each other and a rigid
partition is formed.
A partition constructed in accordance with the present invention
has many practical uses. Since it can be used to transform any open
table area into a cluster of individual carrels, it is of
particular value in the field of education. Communication media
being made available to the individual areas through a jack system
in the separators, hereinafter to be described, allows for
individual instruction and testing. For example, a library or
reading room can be quickly and economically transformed into a
testing area by placing the partitions on the tables. A master
communication system can be connected to a predetermined number of
carrels by means of the jack system in the separators.
The jack system consists of information-receiving jacks 50a, b, c
and d located in the separator 40 as shown in FIG. 7. As shown in
FIG. 9, circuit means 54 connects the information-receiving jacks
to information-distributing jacks 52a, b, c and d on the legs 46a,
b, c and d of the separator 40. Each information-receiving jack can
be connected to just one information-distributing jack or more than
one, as is desired. Since each of the legs has an
information-distributing jack, each area has access to the
communication system.
As shown in FIG. 1, individuals using the areas may use headphones
55, or other devices to receive the communications.
In the alternative, instead of connecting each of the areas to a
master communications system the platform-like portion 44 of the
separator 40 can serve as a table upon which a communication device
such as a tape recorder (not shown) may be placed. The
communication device can then be connected to the various areas by
means of the jack system hereinabove described.
A separator of an alternative construction is shown in FIG. 8. The
separator locking portion 50 is of a unitary construction. The
truncated legs 52a, b, c and d are spaced to create slots 54a, b, c
and d therebetween. The slots created have a width substantially
equal to the thickness of the panels so that when the separator is
placed over the panels the panels are fixedly held in place and a
rigid partition is formed.
Another alternative construction for the separator is shown in FIG.
11 wherein the separator locking portion 50' is of a unitary
construction, having legs 52a', b', c' and d' which are spaced to
create slots 54a', b', c' and d' therebetween.
In order to prevent the partition from sliding along the top 14 of
the table 12 when the partition is in use, the partition may be
releasably fixed to the top 14. As shown in FIG. 1, suction devices
60 may be placed on the bottom of the individual panels so that the
partition will be prevented from moving across the top surface 14
but can be easily removed from the top surface 14, when desired. In
the alternative, a high friction material may be placed on the
bottom of the individual panels to prevent slippage.
An alternative embodiment of the partition is shown in FIG. 10
wherein the table 12' has partition 10' placed upon the top 14'.
The partition is composed of three panels 20', 22' and 24' which
are aligned by separator 40' so that the panels 20, 22' and 24'
extend radially outward from the approximate center of the table
12' and each panel is disposed 120.degree. from the other. Suction
devices 60' prevent the partition from sliding on the top 14'.
It will be recognized by those skilled in the art that the objects
of the present invention have been achieved by a partition
consisting of different panels which are hinged to each other and
which are aligned and secured in place by separators. The
separators make communication media available in each carrel
through a system of jacks.
While in accordance with the patent statutes a preferred embodiment
has been described in detail, it should be understood that the
invention is not limited thereby.
