BACKGRO~ND OF INVENTION
Field of Invention
The present invention relates to a structural
connecting post and clamping connectors to secure space ;
division panels thereto as well as for supporting
articles of furniture in front of the panels and permit~
ting change of height and stackability of panels and
,.
wherein no tools are required to assemble one or more
panels to the connecting post.
Description of Prior Art
Various connecting mechanisms and panel systems
have been provided to divide a space into working
sub-areas and wherein desks, cabinets and other
components are integrated with the partition walls.
Various means of connecting the partition walls have been
suggested and such systems are for example described in
U.S. Patent No. 4,567,698. Many of such systems lack
versatility and flexibility and are usually unstable.
Some of the prior art connectors also act like hinges and
make the panels unstable and this is a major drawback,
particularly with panels where shelving, filing cabinets
or other such articles of furnitures are secured thereto.
This loading of the panels will stresses the connecting
joints and result in eventual breakage. Usually, the
panels are connected at two attachment points along their
vertical side edges with one connecting point at the top
"~
and the other at the bottom of the panels. Existing ~ ~
panel systems are also designed to be of a common height ` ~` ;`
and a change in the height is usually impossible or very
complex to achieve, often requiring a complete reassembly ~
of the system and rendering the system unstable. ~ - ;

2 ~ -d
-'';--...
Other disadvantages of known space division
systems is that they are difficult to install and modifi-
cations thereof can only be done by experienced personnel
thus preventing the user from modifying his space
division walls. Existing panel modules also do not stack
one over another in a vertical plane, nor do they come in
varying sizes or designs and constructions to create
various surface treatment or to simply raise the height
of an actual installation.
There is usually two types of panel systems,
the first one being the straight panel of rectangular
, :,:
shape that interconnects at a given height. It is
difficult with such a system to do a height change in the
panels. When this is required, the manufacturer is often
asked to provlde special components and this becomes
costly and time consuming to install.
The other type of panel system is a panel frame
to which is added tiles. The panel is usually an empty
metal frame available in limited widths and heights and
on which tiles are added on the surface to finish the
.~ . .
panel and create a visual or functional effect. Height
changes are easy in a straight row of panels but much ;
more difficult when the panels are disposed at an angle ;
to one another. These panels are also not stackable in a
common vertical plane.
Most panels of the prior art are difficult to -
assemble and often require special tools. Their assembly
is also time consuming and they cannot be easily modified
after they have been erected in a space division system. -~
They also do not provide flexibility for add-ons and ~-
often it is required to disassemble a large section of
the space division to make a small modification. - -

SUMMARY OF INVENTION
It is a feature of the present invention to
provide a panel connector which substantially overcomes
all of the above-mentioned disadvantages of the prior
art.
A further feature of the present invention is
to provide a panel connector comprised of a structural
connecting post which is the structural element in the
space dividing system for supporting panels, shelving, or
other articles of furniture and the entire weight of the
,:
system is transferred to ground through the connecting
post. ~ `
Another feature of the present invention is to `~
provide a panel connector having a structural connecting
post and to which panels are secured in a top end by a `
removable clamp and further at spaced intervals along the
, .
length of the post to provide a rigid connection with the -
panels.
Another feature of the present invention is to :~
provide a panel connector which can be constructed in .'.~`i,. ,
sections to provide adjacent panels of different heights .
and wherein panels can be connected one on top of each
other in a vertical plane along the post and further
wherein panels of different heights and design can be .-`.~, .
secured to the connecting post. .
Another feature of the present invention is to .-.~
provide a panel connector for interconnecting and ~; '
supporting panels along their side edges to form a space '~
division and wherein the panels are connected to the post , - .
without the use of screws or special tools.
- 3 ~
A further feature of the present invention is
that the panel is not a structural element in the space
dividing system, and is supported elevated (floating).
Accordingly, it can be of light weight construction
making it easy to install.
Another feature of the present invention is to
provide a panel connector having a structural connecting
posi which is provided with a leveling foot at the bottom
end thereof and wherein the foot is easily adjustable to
adjust its height and wherein the foot grips the floor
surface on which it is positioned.
Another feature is to provide hooks along the
side edges of the panels so that the panels can be
attached to the connecting posts quickly to form the
divisions, and thereafter the clamps can be engaged.
Accordingly, the panels are self-supporting without the
clamps permitting repairs to the clamps, if necessary.
Another feature of the present invention is to
provide a panel connector having a structural connecting
post to which end connecting blocks are secured whereby
to connect to other connecting posts and dispose panels
at angles to one another.
j According to the above features, from a broad
aspect, the present invention provides a panel connector
for interconnecting and supporting panels along their
side edges to form a space division. The panel connector
comprises a structural connecting post having a support-
ing bottom end and a securing top end. The connecting
post has opposed parallel side walls. The first pair of
the side walls has panel attachment means in at least one
side thereof and the second pair of side walls has a

the top corner of at least one panel to be secured to
the connecting post. A clamp is associated with the
bracket and has fastening means to rigidly connect the
panel attachment means to the clamp bracket to lock the
panel with the connecting post. The clamp has a
pivoting lever to permit the fastening means to be
located in engagement with the attachment means of the
connecting post and into the arresting means of the
clamp bracket to urge a side edge of the panel firmly
against the side wall of the first pair of side walls
of the connecting post. Hooking means is secured to a
connecting vertical edge of the panel for engagement
with the panel attachment means and spaced from the top
corner of the panel.
According to a further feature of the invention,
there is provided a panel connector comprised of a
structural connecting post and clamps to secure panels
,, -: -,. .
to the post and designed to allow maximum flexibility
to a space division system and which represents a
significant advance in terms of steadiness, ease of
assembly and layout flexibility. The panel system of
the present invention using the novel connector allows
, .: :
to erect a panel layout at a prefixed height with basic
panels and incorporates rows of panels having lower
heights to provide visual access or at much higher
heights to provide standing privacy. The system also ~ ~

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, and more particu-
larly to Figure i, there is shown generally at 10, a
space division system comprised of a plurality of panels
11 of different size, shape and construction, all inter-
connected to one another by the panel connector of the
present invention. As herein shown, furniture modules
such as shelf units 12, cabinet 13, and desk top 14 are
all supported directly by the panel connector of the
present invention and accordingly no load is attached to
the panels themselves. As herein shown, panels of
different height and construction are connected one on
top of another in a common plane and the manner in which
these are connected will be described later on.
~;~ Referring now additionally to Figures 2 to 4,
there is illustrated the basic component parts of a
division system constructed with the panel connectors~of
the present invention. The panel connector of the
invention comprises structural connecting posts 15 and
these may provided as a single post length or may
comprise of post sections 15'. The panels 11, herein
panels of different size, are interconnected to the posts
by a clamp 16 provided in the top end of the panels. At
the bottom end of the connecting post 15, there is also
provided a leveling foot 17 to adjust the level of the
panels after they are secured to the connecting posts 15.

Some of the panels are also provided with clamp brackets
18 which hook to the structural connecting posts lS
intermediate the ends of the posts to provide for a rigid
connection with the post both axially and laterally. As
shown in Figure 3 the panels are assembled in sequence
from the bottom ones to the top ones. The bottom edge of
the panels are supported elevated from the floor surface,
and such are known as "floating" panels. This provides
for ease of adjustment. Once completed, the exposed end
edges and top edges of the panels and connecting posts
are covered by panel top covers 18' connector end caps
19 and side covers 20 to form an aesthetically pleasing
assembly.
A detailed description of the panel connector
,. . .
of the present invention now follows with specific
refPrence to Figures 5 to 8D. As herein shown, the ;~
structural connecting post is a straight elongated post
of substantially square cross-section and defines a first
pair of side walls 21 having panel attachment means in at ~ ;~
least one of the side walls, as herein shown in both side ~;
walls with the said attachment means being constituted by
.,
hook receiving apertures 22. As herein shown there are
four groups of hook receiving apertures 22 along the post
15. The other pair of post side walls 23 are provided
with a plurality of equidistantly spaced connecting slots
24 to which articles of furniture such as the shelf 12,
cabinet 13, and desk top 14, may be connected.
The structural connecting post 15 is provided
with inner end channels 25 formed integral therewith
along corner areas of the first pair of side walls with
the channels 25 forming protrusions extending outwardly
of the side walls 21. The hook receiving apertures 22
:
-- 10 --
~, '
J ~
are formed in a foward end portion of these channels 25.
The hook receiving apertures 22 are also formed in
aligned pairs in the outer end portions of these channels ~ -
and transversely aligned with one another. The reason
for these hook receiving apertures is to interconnect the ~ -
post with the panels 11. As previously described, a
clamp is utilized in the interconnection. As shown in
Figures 5 and 6, a clamp bracket 26 is secured in a top ~;
corner of the top edge 27 and side edge 28 of the panel ' '
11. The clamp bracket is secured by fasteners 29. The -
clamp 16 is herein shown as a detachable clamp but it is ~ ,
conceivable that it could be permanently secured to the : ,
top wall of the clamp bracket and it is comprised by a ',' :,:
pair of hooking fingers 30 and 30' which are formed from ,
a flat metal plate and disposed spaced apart in parallel
relationship. These fingers each have a straight ' ','~
connecting arm 31 and a common ,interconnecting wall 32
and define hooking fingers formed by a bridge wall 33 and
inwardly turned end fingers 34 spaced parallel to the '' '"~
connecting arms 31. The connecting arms 31 are further i'" .'~:''~
~.... ...
;~ pivotally connected by a pivot connection 35 at a free
: end thereof to a pivoting lever 36. The pivoting lever ,'~"''':- '
- 36,,is provided with a wedge end 37 extending forwardly
: thereof. ' 'I.''''','
As better illustrated in Figure 6, the top wall ' ~
38 of the clamp bracket 26 has a clamp post 39 extending '~,.',,i;','~,.`-,
~:: thereabove and formed integral therewith. This clamp ;''~
, "; ~ ,, ~, -,
post 39 is provided with an undercut abutment wall 40 for ;',,''-, '
receiving the wedge end 35 of the pivoting lever in
locking engagement therewith, as illustrated in Figures ,'',~,.. ~,',".,
8A to 8D. The lever 36 has a finger engaging end portion
41 and a slot aperture 42 is formed in a free end wall '~,
thereof to permit entry of a wedging tool, such as a
screwdriver under the pivoting iever to disconnect it
from the top edge 27 of the panel 11 when it is in a
clamping position, as shown in Figure 8D. By wedging the
pivoting lever upwardly, it will snap open to cause it to
disconnect with the connecting post.
As shown in Figure 6, the clamp bracket 26 is a
right-angle bracket and defines a connecting end face 43
provided with a pair of hook receiving cavities 44
constituting an arresting means for the hooking fingers
30. As previously described, the side edge 28 of the
panel 11 is provided with one or more clamp brackets 18.
Each clamp bracket is provided with one or more pairs of
hooking fingers 45 projecting therefrom to engage with
two or more pairs of hook receiving apertures 22 provided
in the post 15. Accordingly for securing the panel to
the post, one firstly positions the hooking fingers 45
within respective ones of the apertures 22 in the top end
of the post aligned with the top edge 27 of the panel 11.
As shown in Figure 8A, the clamp, which is
herein a separate element, is positioned with the hooking
fingers 34 extending inside the post with the finger end
34 extending through the top aperture 22', as shown in
Figure 6, and entering into the hook cavities 44, as
shown in Figure 8B. The wedge end 35 is positioned
behind the clamp post 40 and the pivoting lever is pushed
downwardly towards the top edge 27 of the panel, in the
direction of arrow 47, as shown in Figure 8C. This
causes the bridge wall 33 of the hooking fingers to urge
the post and panel in clamping engagement, as shown in
Figure 8D. The hooking fingers 30, being located in the
hook cavities 44 prevent lateral movement of the panel
- 12 -
,? ~, ?J ~j ~
with the connecting post. Also, as shown in Figure 6,
the top edge and side edge of the panel are recessed from
the panel front wall 48 and rear wall 49 thereby further
preventing lateral movement. However, the main reason
for the hook receiving cavities 44 is to prevent axial
displacement between the post and the panel. When the
hooking fingers are received in the hook receiving
cavities, the hooking fingers 45 of the clamps 18 can no
longer move out of their respective hook receiving
apertures 22. The hook plates 18 have a flat connecting
wall 50 having holes therein to receive fasteners 51 to
secure it to the panel side edge 28.
As shown in Figure 5, the top edge 27 of the
panel 11 is provided with clips 52 having opposed
flexible prongs 53 to retain in snap-fit therewith the
, . . .
panel top cover strips 18' to provide an aesthetic finish
to the panels. The top cover strips 18' extend over the
clamp assemblies 16. As herein shown, the bases of the
panels are also provided with a hollow base channel 54 to
run communication and electrical cables therein, as is
well known in the art. The base of the post 15 is
provided with a support extension post 55 to which is
connected the leveling foot 17. As shown in this Figure,
there are two clamp brackets 18 in the side edge 28 of
the panels 11. These clamp brackets provide for a stable
connection of the panels with the posts, and further
provide for preinstallation of all the panels and posts
15 without using the clamp 16. Once the space division
set-up is completed, the clamps 16 are then engaged.
Accordingly, the system is more flexible and faster to
install and modify.
~ $ -~ .s ` .~
Referring now to Figures 9A, 9B and 9C, there
will be described the construction and operation of the
leveling foot. As herein shown, the leveling foot is
provided with an adjustment screw 57 which is in threaded
engagement with a threaded bore (not shown) provided in a
lower end of the extension post 55. The adjustment screw
57 is secured to a rotatable block 58 which is rotatably
supported on a gripper base 59. The gripper base 59 is a
flat nylon disc having sharp cone-shape prongs 60 formed
integral therewith and extending from a lower surface
thereof to constitute a gripper means to prevent shifting
or lateral displacement of the leveling foot on a support
surface which is usually carpeted surface. The nylon
disc 59 is also formed with a sleeve connector 61 extend-
ing above a top surface thereof and which is received in
rotatable engagement within an annular groove formed in a
bottom face of the rotatable block 58.
The rotatable block is also provided with two
or more, herein three tangential bores 63 in the side
wall 64 thereof for the insertion of a rod-like element,
such as the screwdriver 65, therein to rotate the block
58 on the gripper base 59 which remains stationary by the
prongs 60 firmly engaged in the support surface. Accord-
ingly, the screw 57 can be rotated and the level of the
panels connected to the post can be adjusted.
As previously described, panels of different
heights may be connected to a common structural connect-
ing post as is illustrated in Figures llA to llC. As
herein shown, the panel 11' is a taller panel than panel
11" with panei 11" terminating at an intermediate group
of hook receiving apertures 22 and being secured thereto
by the clamp assembly 16'. Accordingly, both panels are
~' .
- 14 -
~ '
2 ~ 2 ~
rigidly interconnected to the common connecting post 15'.
The panel top covers 18' are then secured to the top edge
of both panels 11' and 11", as shown in Figure llB.
Thereafter, a short side cover 20 is secured to the hook
receiving apertures 22 in the top portion 15" of the post
15' in a manner as illustrated in Figure 14A. The
connector end cap 19 is then snap-fitted into position.
Accordingly, an aesthetic configuration of two panels of
different heights is created. This configuration can
also be created with the panels extending at right
angles, as shown with further reference to Figures 12A to
12C. As herein shown the connecting post is formed of
connecting post sections 70 and 71 with the section 71
accommodating the longer panels sections 72. One of the
connecting sections 70 or 71, herein the top section 71
has a straight anchor tongue 73 welded between the end
~: . - . : -
channels 25 in one of the side walls 21. The anchor
tongue has an anchor bushing 74 secured to a free end
thereof, the bushing being formed of a plastic material
and defining two opposed flexible arms 75 each having an
engagement shoulder 76 configured to engage under a
respective one of the hook receiving apertures 22'
provided at the top of the lower connecting post section
70. As herein shown, the tongue member 73 is a flat
rectangular member which fits within the cavity 77
defined between the end channels 25. The length of the
tongue member 73 is such that the engaging shoulders 76
will engage under a pair of hook receiving apertures when
both ends of the bottom and top connecting post sections
meet. A side cover section 20 and connector end cap 19
.~' :',,'','

is then secured about the upper connecting post section
71, as shown in Figure 12C and the panel top covers 18'
are snapped into position to produce an aesthetically
finished product.
As shown in Figure 12A, the structural connect-
ing posts 70 are interconnected at right angle to one
another by two or more interconnecting rectangular bl.ocks
80. The configuration of the block 80 is better
illustrated in Figure 13A where two panels 11 and 11' are
connected in planar alignment but spaced from one another
by the interconnecting blocks 80. These blocks are
connected to flat outer side walls 81 of opposed connect-
ing posts 82 by conventional fastening means 83. The
connecting blocks 80 have opposed parallel connecting
faces 84 with the faces having pairs of aligned slots 85
therein and threaded bores 86 to connect to the connect-
ing posts 82. Accordingly, through these connecting
blocks 80, panels can be interconnected together to form
L-shape or right-angle corners as shown in Figure 15A or
to form a T-configuration as shown in Figure 17A.
Figures 15A and 17A will not be described as the descrip-
tion thereof is obvious in the light of the description
oflFigure 13A. Figures 15B and 17B are merely top views
of Figures 15A and 17A respectively but with the top
covers 18' and end caps 19 snap-fitted to the panels and
the connectors.
Referring now to E'igure 10, there is shown the
manner in which these connecting blocks are secured to
the connecting posts 82. As herein shown, connecting
blocks are secured in opposed ends of the two posts with
one being secured substantially midway therealong. An
elongated vertical side cover 20 is then secured to the
- 16 -
slots 85 of the connector blocks in a manner similar to
that as shown in Figure 13A where the cover strips 87 are
: : .
secured. These cover strips 87 are provided with hooks
88 which engage within the slots 85 and held in position
by their hooks. In order to remove the strlps all one
has to do is pull the strips upwardly and outwardly from - ;~
; ., .
the connecting blocks.
E'igure 16A is a top view showing the connecting
post of Figure 5 connected to opposed panels 11. Figure
16B shows the top cover plate 18' connected to the top
edge of the panel 11. As shown in Figure 16A, a shield~
: : . ,. :.
ing flexible strip 90 of opaque color or of a color
: ` ~ , . ::
matching that of the connector post 15 is slid from the
top end of the connector post to mask the connecting slot
24 provided in the front end rear side walls 23 of the
post 15. Other configuration of shielding strips, such
as the strip 91, as shown in Figure 17A is also used for
the same purpose. Figure 15A shows the two right-angle
panels 11 of Figure 10 interconnected together with a
connector side cover 20 being secured to the square
connecting blocks 80.
Referring now to Figures l9A and 20A, there is
shown a triangular interconnecting block 95 for inter-
1~ ' :': ' ,.' '' '' :',
connecting two or three connecting posts, such as thepost 82 at angles of 120 with respect to one another.
These triangular connectors are constructed similarly to
,. : ,,, :,:
the square connectors with the exception that they are
not provided with slots 85. Instead, a strip support
connector 96 is secured to an open face of the triangular
block and it is provided with slots 97 to receive the ;~
hooks 98 of an angle covering strip 99, as shown in `~
Figure l9A.
