Description
BACKGROUND OF THE INVENTION
In prior art space divider partition systems individual partition
panels are generally free standing and have perpendicular
supporting legs positioned at their lower portions. To form a wall
or space divider the panels are placed in abutting relationship.
Since the separate panels are not secured together some of them may
shift out of alignment rendering an unsightly appearance. Some
systems include an elongated hinge or the like connected between
adjacent pairs of panels allowing them to be shifted at an angle
with respect to each other. These systems are however, typically
complicated. Links have also been provided at the top and bottom of
a pair of panels to allow swinging with respect to each other but
these are generally found to be wobbly both laterally and
longitudinally with respect to each other. Also, when one partition
is rotated with respect to another, the inside corner defined by
the partitions takes on an unsightly, staggered appearance. In
other systems rigidly bolted connectors are used to fix pairs of
panels together. These rigidly fixed connectors however do not
facilitate the changing of the angle of the partitions with respect
to one another and separate angle connectors must also be provided.
These and other systems all suffer from the drawback that many
complicated brackets and special connectors must be provided for
each different arrangement of panels.
SUMMARY
The present invention overcomes the disadvantages of the prior art
partition systems in its provision of a single inexpensive link
member which makes it possible to provide in line or angular
arrangements of partitions using only a single basic linking
component. The link includes a first set of connectors for
cooperating with the fastening means on adjacent partitions to join
the partitions together in aligned relationship. A second set of
connectors are provided for cooperating with the partition
fastening means for joining them in an angular relationship with
respect to one another.
As a result of this construction, the first connectors can be made
to facilitate rigid, inline connection of the partitions and the
second set of connectors can be constructed so as to facilitate
pivotable, angular connection. Further, the second set of
connectors can be oriented with respect to the link as a whole in
such a way that when the second set of connectors is used to join
the link to a first partition, the joining point for a second
partition is actually out of alignment with the first partition.
This makes it possible to provide a smooth and less staggered
inside corner appearance when two partitions are joined together in
an angular relationship with respect to each other.
The many important objects and advantages of the present invention
will be more fully appreciated by those skilled in the art when
reading the following description with reference to the
accompanying drawings illustrating a preferred embodiment of the
invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The partition system of the present invention employs a specially
configured connector member 40 (FIG. 4) to connect pairs of
adjacent partitions 10 together in alignment or at angles with
respect to each other to efficiently provide a space divider system
for modern modular office layouts. A representative partition
assembly is shown in FIG. 1 wherein a plurality of partitions 10
are arranged in a space dividing layout. A number of modular
components as desks 30 a shelf 32 files 34 and the like are
positioned on the partitions and held in place by a conventional
hook-type bracket 36. Adjacent pairs of partitions 10 are secured
together in alignment with each other or at an angle with respect
to each other by means of special connector or link 40 (FIGS. 2, 3
and 4) as will be more fully described hereinafter.
Referring to FIGS. 5 and 6, partitions 10 have a general hollow
interior formed of sheet metal vertical channels 12 an upper
horizontal channel 14 and a lower horizontal channel 16. The
various channels are welded to each other to form the interior
framework. Cover panels 18 made of particle board or the like are
fixed over the interior framework and are covered with a decorative
fabric 20 or the like. The side edges of the partitions include
decorative trim strips 22 and the top edges are provided with a
removable decorative cap or cover 24.
Partitions 10 are supported at the bottom on support brackets 50
(only one is shown) positioned adjacent side trim strip 22. Lower
supports 50 are welded to the lower horizontal channel 16 and
support the entire weight of the panel. Leveling guides 52 threaded
into lower supports 50 serve to level the partitions on a floor
surface in a conventional manner. Support 50 includes an outwardly
extending, threaded, apertured portion 60 to receive fastening
means to secure linking member 40 as will be more fully described
hereinafter.
Upper horizontal channel 14 is shaped as an inverted U and extends
along the top of the partition assembly below cover 24. At its
ends, adjacent, and forming part of the side trim strip 22, upper
horizontal channel 14 has a threaded plate member 26 which includes
two spaced apart tapped openings 28 at the end corners of partition
10 to receive fastening means for securement of linking member 40
at the upper portion of the partition (FIG. 2). A third tapped
opening 28a is positioned rearwardly and centrally with respect to
openings 28.
Removable cover member 24 is equipped with spaced spring clips 25
adapted to engage and embrace upper horizontal channel 14. Cover
member 24 is also formed of sheet material and has a generally
hollow interior. When positioned to cover the top of a panel
assembly a slight gap exists at the ends of cover 24 adjacent side
trim strips 22 to allow link 40 to extend therefrom (FIG. 6).
Link 40 (FIG. 4) has a generally rectangular main body portion 42
with a series of spaced openings 43 placed generally at the corners
of the rectangle. An additional opening 44 is positioned generally
in the center of the rectangular main body portion. A leg 45
extends outwardly from the body from the longer side thereof and
includes an angular edge or wall portion 46 extending from one of
its longer sides outwardly to form an intersection with an
outermost rounded extremity or head 47 of the leg 45. An opening 48
is provided in the rounded end of the leg and another opening 49 is
positioned along the length of leg 45, generally adjacent the
intersection of angular edge 46 with the rounded end portion or
head 47.
It will be noted that the first set of connector holes 43 of link
40 are used to join the partitions 10 together in aligned
relationship while the holes 44, 49 and 48 provide a second set of
holes which facilitate joining the partitions together in a
pivotable, angular relationship with respect to each other. The
first set of holes 43 are oriented generally at the corners of the
main body portion 42 in a regular, rectangular fashion such that
when the respective fastening means 70 and 72 of the respective
adjacent partitions are passed therethrough, the entire link 40
lies in alignment with the two partitions. Even the projecting leg
45 is positioned in alignment with the first partition. This,
coupled with the relative size of link 40 with respect to the size
of the partitions insures that all of link 40 will lie within the
confines of the opposite faces, defined by surface panels 20, of
the partitions and, except for its side edge, will not be exposed
to view.
The second set of cooperating connector holes, however, are
oriented with respect to link 40 in such a way that when holes 44
and 49 are secured to one of the partitions 10 by means of bolt 72
passing through hole 44 and into hole 28a at the top of partition
10 and fastener 70 passing through hole 49 and into a corner hole
28, link 40 is cocked at an angle with respect to the longitudinal
plane defined by the partition 10 and leg 45 actually projects out
of alignment with respect to partition 10. In this way, the point
of connection for the adjacent partition, i.e., hole 48, is offset
from alignment with the first partition such that a smoother inside
corner is obtained when the two partitions are joined together
(FIG. 3). If the point of connection 48 for the second partition
were in alignment with the first partition, the inside corner
defined by the two partitions would have a more staggered
appearance and would not be as attractive to the user.
As an aid to the user, the face of link 40 is stamped with a line
40a which connects the first set holes 43. This advises the user
that these holes are to be used in conjunction. Similarly, the
second set holes 44, 49 and 48 are connected by a second line 40b
stamped into the face of link 40 to show the user that these holes
are used in conjunction.
It should be noted that the angle of angular wall 46 of link 40
with respect to the body 42 of link 40 is such that this edge wall
46 does not project beyond the confines of the space between the
opposing faces of the partitions when the second set of holes, 44,
49 and 48, are used. At the juncture of angular edge wall 46 with
the head 47 of leg 45, an inwardly recessed notch 51 is defined.
This makes it possible to provide an enlarged head 47 to ensure a
rigid connecting point for the angularly disposed partition, and
yet eliminates excess material which would otherwise project
outwardly into the space at the inside corner defined by the two
partitions.
Openings 43, 44, 48 and 49 in link 40 are slightly oversize with
respect to the bolt size which passes therethrough into the
retaining means in the panels and in the lower support bracket. The
holes are also spaced apart a predetermined distance on the link so
that any selected adjacent pair of openings will be in general
alignment with any selected pair of adjacent threaded openings in
the retainers. The link accordingly can be positioned in an
adjacent pair of threaded openings in the partitions to thereby
connect pairs of partitions at an angle or in line with respect to
each other as will be hereinafter described.
Lower support bracket 50 shown in FIG. 7 includes apertured portion
60 in which a series of spaced apart threaded openings 61, 62 and
63 are provided. The threaded openings 61 and 62 are positioned
adjacent the outermost ends at the corners of apertured portion 60
while opening 63 is generally centrally located and spaced inwardly
a slight distance. The spacing and alignment of the threaded
openings in the support bracket corresponds to that of the openings
28 and 28a in threaded plate 26 located at the upper portion of the
partitions. When the panels are assembled, threaded plate 26 and
the threaded apertured portion 60 of lower support 50 are arranged
to be in vertical alignment at the side edges of each individual
partition 10.
Lower support 50 includes a central threaded aperture 53 which
receives the corresponding threaded portion of leveling guide 52 in
a conventional manner. An aperture tongue like projection 54
opposite aperture portion 60 is utilized to support closure
mechanisms (not shown) for the base of the wiring channel formed in
the base of the panels. The structure and operation of lower
support 50 other than the aperture portion 60 form no part of the
present invention, and accordingly, will not be described in
greater detail. For a more detailed discussion of lower support 50
and its novel features, reference may be had to copending, commonly
assigned, application entitled SUPPORT SYSTEM FOR PARTITIONS, U.S.
Ser. No. 401,625 invented by Alexander A. Karrip, filed on even
date herewith, and incorporated herein by reference.
To facilitate assembly an upwardly extending tapered stud 70 is
fixed in one of the threaded openings 28 of plate 26 (FIGS. 2 and
5). The studs are preferably provided on each end of an individual
partition at opposite sides thereof so that when a pair of
partitions are placed in abutting relationship as shown in FIG. 2
the link may be conveniently dropped over the studs which serve to
temporarily hold the link in position. To secure a pair of
partitions in abutting relationship all that is required is to
insert bolts 72 through adjacent holes in link 40 and fasten them
securely into the top edge of the partition in threaded plate 26.
The lower portions of an adjacent pair of partitions are similarly
secured by removing the cover plate 21 at the lower portion (FIG.
5) and positioning a link over adjacent threaded portions 60 of
lower support bracket 50. The link is secured at the lower support
by a bolt 72 passing through the openings in the link and into
corresponding theaded openings 61 and 62 in the lower support.
Decorative cover plate 21 and top cover 24 are then replaced and
the assembled partitions are ready for use.
In FIG. 3 the angular relationship of a pair of partitions is
illustrated wherein openings 44 and 49 in the link are used to
secure the link to one of the partitions while opening 48 in the
leg is utilized to secure the adjacent partition at an angle with
respect to the first. In this arrangement stud 70 in the left hand
partition passes through opening 49 and the centrally threaded
opening 28 receives fastening means 72 through opening 44 in the
link. In the adjacent panel only one threaded opening is utilized
to receive fastening bolt 72 passing through opening 48 in the leg
of the link. Stud 70 is not utilized in the adjacent partition at
this time. The lower portion of the partitions are similarly
affixed by means of an identical link 40, bolts 72 and stud 70
passing through and secured in the threaded portion 60 of lower
support 50. One slight variation is that a stud 70 is used at the
bottom of partition 10 to pass through hole 48 in head 47 instead
of a bolt 72 so that connection is effected at this point by simply
setting the head 47 of link 40 over stud 70 at the bottom of
partition 10. Those skilled in the art will recognize that
virtually any desired angular relationship of a pair of adjacent
partitions can be achieved through the use of the novel link
structure of the invention. When not in use the link can be
conveniently stored within the partition assembly by simply facing
the leg inwardly and securing the link in place by means of the
bolts provided. When the cover 24 is fixed in place only the side
edge of the link is visible and it may be plated or finished to
complement the finish of the partition assembly.
Those skilled in the art will recognize other arrangements of the
invention can be provided. All modifications of the invention are
to be considered as included in the appended claims unless these
claims by their language expressly state otherwise.
