ADJUSTABLE POLE SUPPORT SYSTEM
Abstract
A system of shelves, cabinets, lighting fixtures and other
accessories is adjustably horizontally supported on vertical poles
removably located between the floor and ceiling of a dwelling or
other structure without structural damage thereto. The poles are
designed for easy vertical alignment, provide numerous locations
for article support mounting pins and may be easily decorated with
caps which conceal mounting pin apertures from view. The wide
variety of articles supportable by the pole system are prevented
from relative rotational movement with respect to the poles by
coaction between article supports and channels formed in the
poles.

Description
The present invention relates generally to adjustable, supported
furniture assemblies, and in particular to a pole supported
furniture system in which furniture and accessories are removably
mounted on vertical poles in a stable, horizontal arrangement.
The desire for variation in furniture arrangement, changing needs
with regard to type and style of furniture and the need for
semi-permanent location of changeable furniture units without
attendant structural damage of leased premises has resulted in the
popularity of adjustable pole-supported furniture systems. In
addition to residential requirements, various commercial
establishments require flexible storage and display facilities to
cope with changing needs and the desire for presentation of
attractive and decorative displays.
In typical examples of pole-supported furniture assemblies on the
market, article support means are attached to poles by complicated
and expensive mechanical contrivances in order to ensure rigid
semi-permanent attachment of articles thereto along with resistance
of the supported articles to rotational movement. Other attempts at
solution of the problems of semi-permanent rigidity and rotational
stability require the use of screws or other semi-permanent
fastening means resulting in marring of the poles thereby greatly
reducing flexibility of the system due to the appearance of
unsightly remnants of previous arrangements.
Although, as noted above, pole supported adjustable furniture
systems are available on the market, such systems are often
expensive, limiting in the use which can be made therewith of
"ordinary" furniture, difficult to assemble and adjust, unsightly
when used in conjunction with electrical apparatus, and unstable
when subjected to unbalanced loads. It would be desirable to
provide a stable, easily installed and easily varied pole supported
furniture system which was simple and inexpensive to manufacture,
capable of maximum decorative use and adornment, and which could
utilize cabinets, shelving materials and panelling of many
different manufacturers. Further, a desired apparatus should be of
a stable construction and permit the concealment of electrical
conductors for lamps, radios, clocks, electronic equipment and the
like which might be contained on or in the furniture suspended from
the poles. Still further, a desirable system should be sufficiently
flexible to permit the arrangement and easy rearrangement of a
mixture of all of the various items of furniture mentioned.
Broadly, it is an object of the present invention to provide an
adjustable pole supported furniture system which realizes one or
more of the aforesaid objectives. Specifically, it is within the
contemplation of the present invention to provide a pole supported
adjustable furniture system for supporting articles of furniture
and the like which is simple to assemble and disassemble, permits
virtually unlimited variety in arrangement and use of materials and
results in a stable, non-permanent, variable furniture unit.
In accordance with an illustrative embodiment demonstrating objects
and features of the present invention, there is provided an
adjustable pole support system comprising, in combination, at least
two vertical support poles and means for vertically mounting said
poles. Each of the poles comprises a vertically extending body
having first, vertically extending left and right channels each
having a rear wall. Left and right side walls extend outwardly from
said left and right channel rear walls defining said left and right
channels therebetween. Front and rear flanges extend outwardly from
each of the left and right side walls with the ends of the flanges
forming lips in a manner that second, front and rear channels are
defined thereby and are bounded respectively by the side walls, the
flanges and the lips. A plurality of horizontally opposed pairs of
vertically spaced apertures appear in at least two of the side
walls of the poles, each of said apertures extending between one of
said first channels and one of said second channels. The apertures
are of a size to accept pin means, two of which are provided and
are supported by a pair of said horizontally opposed vertically
spaced apertures. At least two article supports are provided for
use in horizontally supporting an article between the poles. The
article supports comprise a face which is constructed and arranged
to horizontally support at least a portion of the article. A first
attachment means on the article support removably fixes the article
support to the pin means. A second attachment means on the article
support is vertically spaced from the first attachment means and is
constructed and arranged to coact with a channel of a pole to
maintain the article support substantially horizontal under the
application of torsional forces to said article support.
The above description, as well as further objects, features and
advantages of the present invention will be more fully understood
by reference to the following detailed description of a presently

Referring now specifically to the drawing, and first to FIG. 1,
there is shown an illustrative adjustable pole support system
embodying features of the present invention, generally designated
by the reference numeral 20, which includes four substantially
identical poles 22 which are vertically supported between a ceiling
C and a floor F in a manner to be described in detail hereinafter.
In this illustrative form of the invention, a number of articles
are shown horizontally supported by the poles 22 including shelves
24, a cabinet 26, a chest of drawers 28 and a light bar 30.
The constructional details of the pole 22 are best seen in FIGS. 2
and 3 wherein the pole, which may be fabricated of brake-formed or
roll-formed steel or other suitable material, is shown as being
composed of two substantially identical vertically extending
channel bars designated herein for convenience of notation as left
and right pole sections 22a, 22b. The letters a and b are used
throughout the description to denote, respectively, left and right
substantially identical structures.
Centrally located, vertically extending left and right rear walls
30a, 30b of left and right pole sections 22a, 22b are attached to
one another by any convenient means of permanent fastening, such as
by spot welding or the like. Front and rear left and right side
walls 32a, 34a, 32b, 34b extend outwardly from left and right rear
walls 30a, 30b at right angles thereto in opposite directions from
said rear walls on opposite sides of the pole 22. Front and rear
left and right flanges 36a, 38a, 36b, 38b extend outwardly from the
respective side walls 32a, 34a, 32b, 34b at right angles thereto
and terminate in right angle, inwardly directed lips 40a, 42a, 40b,
42b.
Thus, due to the constructional configuration of the pole sections
22a, 22b, vertically extending left and right channels 44a, 44b are
formed within the pole 22, bounded respectively by the rear walls
30a, 30b, the front side walls 32a , 32b and the rear side walls
34a, 34b. In addition, vertically extending front and rear channels
48, 50 are formed within the pole 22, defined respectively by the
juxtaposed substantially co-planar front and rear, left and right
side walls 32a, 32b and 34a, 34b, the substantially parallel front
and rear, left and right flanges 36a, 36b and 38a, 38b, as well as
the front and rear, left and right lips 40a, 40b and 42a, 42b.
A plurality of vertically spaced apertures 52 (best seen in FIG. 5)
appear within each of the side walls 32a, 32b, 34a, 34b (see FIG.
3) and extend between two adjacent channels, i.e., channel 44a and
either channel 48 or 50, and channel 44b and either channel 48 or
50 (see FIG. 2). Consequently, both the front and rear channels 48,
50 are in communication with the left and right channels 44a, 44b
for a purpose to be described hereinafter.
In order to conceal the apertures 52 from view at the front of the
pole system 20, vertically extending front and rear channel caps
54, 56 are provided which include ears 58, 60 thereon for
engagement with lips 40a, 40b, 42a, 42b, permitting removable
attachment of said caps to the front and rear channels 48, 50. The
caps 54, 56 may be plain on their outer faces 62, 64 as
illustrated, or the outer faces thereof may include various designs
thereon. The caps 54, 56 may be made of any suitable material such
as plastic in colors or various wood grain effects, or may be made
of metals or other material to match or contrast with the material
and finish of the poles 22.
The lower ends of the poles 22 are maintained in a relatively fixed
position on the floor F (see FIG. 1) by the use of a floor bearing
pad 66, which is made of any suitable material such as rubber or
the like. The floor bearing pad 66 may be supplied in a set of
three similar pads of three different thicknesses to aid in
vertical mounting and positioning of the pole described more fully
hereinafter. The floor bearing pad 66 includes a countersunk
opening 68 located centrally therein (see FIGS. 3 and 4) for use in
fastening the pad to the floor F as by screws or the like. The
floor bearing pad 66 includes front and rear channel engaging
bosses 70, 72 which, when the floor bearing pad 66 is fastened to
the floor F and the pole 22 is placed thereon, extend into the
lower ends of the front and rear channels 48, 50 to aid in
stabilizing the lower end of the pole (see FIG. 4).
In the event that it is desired or necessary to use the pole system
20 on a rug or carpet, a rug bearing pad 74 (See FIG. 4) is
provided which may be made of the same material as the floor
bearing pad 66 and which includes a plurality of teeth 76 on the
bottom thereof for engagement with carpet pile thereby rendering
the rug bearing pad relatively immobile with respect thereto. The
floor bearing pad 66 is inserted into the bottom of the pole 22 and
the combination is inserted into a depression 78 within the rug
bearing pad 74. In the event that a more permanent affixation of
the rug bearing pad 74 to the carpet is desired than can be
accomplished by the use of the teeth 76 alone, a countersunk
opening 80 is provided in the rug bearing pad to permit a more
secure fastening of the rug bearing pad to the sub-flooring as by
screws or the like (not shown).
The upper portion of the pole 22 is held between the ceiling C and
the floor F by virtue of compressive forces exerted on the pole 22
by any one of a variety of means. In the preferred embodiment
illustrated, a generally cylindrical sleeve 82 (see FIG. 4)
includes a slot 84 therein of sufficient width to enable the slot
to straddle the top of the combined rear walls 30a, 30b. A ceiling
bearing pad 86 is inserted on the top of the sleeve 82, is secured
thereto by, e.g., pin means (not shown), and is designed to bear
against the ceiling C. The aforementioned compressive force is
supplied by a spring 88 contained within the sleeve 82 which bears
against the ceiling bearing pad 86 and the combined rear walls 30a,
30b. The spring 88 is compressed by the positioning of the pole 22
between the floor F and the ceiling C. The compressive force may be
varied by, for example, shortening the length of the sleeve 82 by
any convenient means.
In order to support the shelves 24 in relatively fixed relation to
the poles 22, a shelf support bracket 90 is provided (see FIGS. 9
and 10) which may be made of any suitable material such as sheet
steel or the like. The shelf support bracket 90 includes a face 92
which has a flanged lower portion 94 bent at a right angle thereto
which is designed to support one end of a shelf 24. The upper
portion of the shelf support bracket 90 is of a width equal to the
width of the left or right channels 44a or 44b and has two right
angle bends therein forming a shelf support bracket hook 96.
The shelf support bracket hook 96 is designed to engage a bracket
support pin 98, in a manner to be more fully described hereinafter.
A suggested form for the bracket support pin 98, shown in FIGS. 4
and 6, includes a pin of generally circular cross section and of a
length to be supported by a pair of horizontally opposed apertures
52 in either the left or right channel 44a or 44b. The bracket
support pin 98 includes ends which lie in non-parallel planes to
prevent accidental disengagement of the pin from the apertures
52.
To aid in providing lateral stability and the maintenance of a
horizontal attitude for the shelves 24, even when subjected to
torsional forces due to unbalanced loading thereof, a lateral
support tab 100 (see FIG. 10) is formed in the face 92 of the shelf
support bracket 90. The lateral support tab 100 is of a width
substantially equal to the width of the left or right channels 44a
or 44b and projects rearwardly from the face 92 to contact side
walls 32a and 34a or 32b and 34b of the pole's left or right
channel to provide the required lateral stability.
FIGS. 11 and 12 best illustrate an alternate shelf support bracket
90c, which has a face 92c, which vertically spans a number of the
vertically spaced apertures 52. A flange 94c projects outwardly
from the face 92c of the shelf support bracket 90c, and may either
be of sufficient outward extent to support a shelf 24 in the manner
of flange 94 of shelf support bracket 90 or, in the alternative,
may be somewhat shorter and designed to mate with a cove 102 of a
shelf 24c, as shown in FIG. 12.
The upper end of shelf support bracket 90c is of a width
approximately equal to the width of left or right pole channels 44a
or 44b, and forms a shelf support bracket hook 96c with a forward
facing opening for engaging an upper bracket support pin 98. The
lower end of shelf support bracket 92c is likewise of the width of
the left or right pole channels 44a or 44b and forms a rearwardly
opening hook 104 for engaging a vertically spaced, lower bracket
support pin 98.
Numerous articles of "standard" manufacture, other than shelves,
may be supported from the pole system 20 such as the cabinet 26 and
the chest of drawers 28. The poles 22 are spaced sufficiently apart
to accommodate the width of the "standard" articles. Any shelves 24
to be included between poles 22 which will support other articles
of furniture must, naturally, be selected of a length compatible
therewith.
For mounting "standard" articles of furniture on the pole system
20, a mounting strip 106 is provided (see FIG. 14) which includes,
formed in the face thereof, a plurality of mounting hooks 108 of a
width substantially equal to the width of the left or right
channels 44a or 44b. A number of openings 110 are provided in the
face of the mounting strip 106 for use in attachment of the
mounting strip to, for example, the cabinet 26 by the screws 112 as
shown in FIG. 13. One or more mounting strips 106 may be attached
to the articles of furniture to be supported by the pole 22,
depending on the size thereof and the support required.
In addition to the shelves 24 and 24c and the other articles of
furniture which may be supported by the pole system 20, various
other items may be similarly added thereto. For example, support
bar 30 has a mounting strip 114 (see FIG. 15) attached to each of
the ends thereof. The mounting strip 114 includes hooks 116 spaced
to engage support pins 98 for mounting of the support bar 30
between adjacent poles. In the embodiment illustrated, a plurality
of incandescent bulbs 118 are shown contained within fixtures 120
attached to the interior of the support bar 30 by brackets 122.
In assembling the adjustable pole support system 20, components of
equal length are selected to be supported between adjacent poles 22
and floor bearing pads 66 are located predetermined distances apart
on the floor F. If additional stability is desired, the floor pads
66 are affixed to the floor F by the use of a screw or the like
inserted through the aperture 68 within each floor bearing pad.
The spring 88 is placed within the sleeve 82, the ceiling bearing
pad 86 placed on the top of the sleeve and the entire sleeve
assembly is placed with the slot 84 straddling rear walls 30a and
30b of a pole 22. The pole 22 is located in registry with the
positioned floor bearing pad 66 by placing the ceiling bearing pad
against the ceiling over the floor bearing pad and the spring 88 is
compressed by forcing the pole 22 upward. The pole 22 is then
lowered over the floor bearing pad 66 in a manner that the front
and rear channel engaging bosses 70, 72 engage the front and rear
channels 48, 50 of the pole. If necessary, the sleeve 82 may be
shortened by any convenient means, e.g., a hacksaw, to increase the
compressive force applied to the pole.
The next adjacent pole 22 is positioned in a like manner, the
above-mentioned predetermined distance from the first pole with the
left and right channels of the respective poles facing each other.
One or more floor bearing pads 74 of varying thickness is inserted
beneath the second pole to horizontally align corresponding
apertures of adjacent poles and also aid in providing the necessary
compressive force to maintain vertical stability.
Naturally, if the adjustable pole system 20 is to be assembled on a
rug or carpet, the rug bearing pad 74 would be placed on the rug
prior to the placement of the pole 22. Also, if it is desired, the
rug bearing pad 74 may be used as the sole lower stabilizing means,
the floor bearing pad 66 being dispensed with, if the proper
horizontal alignment of corresponding apertures and sufficient
compressive force is obtainable without the use thereof.
To support one of the shelves 24, a bracket support pin 98 is
placed in two horizontally opposed apertures 52 in the side walls
of, for example, the right channel 46 of a pole 22. A shelf support
bracket 90 is placed with the shelf support bracket hook 96 over
the bracket support pin 98. Another bracket support pin 98 is
placed at a corresponding vertical location within two horizontally
opposed apertures 52 of the left channel 44 of a facing, adjacent
pole 22 and another shelf support bracket 90 is placed with the
shelf support bracket hook 96 thereof over the other bracket
support pin 98. The shelf 24 is then placed with its ends on the
flanges 94 of the facing shelf support brackets 90. Fastening means
such as screws 124 (see FIGS. 9 and 10) may be used to fasten the
shelf 24 to the shelf support brackets 90. In position in this
manner, tabs 100 of the shelf support brackets 90 provide the
required lateral stability and maintenance of horizontal position
despite subjection of the shelf 24 to torsional forces by
nonsymmetrical loading thereof.
As an alternative to the bracket support pin 98 designed to fit
within apertures 52, a bracket support pin 98c (see FIG. 8) may be
provided which is straight for its entire length and which has
enlarged end pieces 126 requiring alternate apertures 52c as shown
in FIG. 7. Naturally, other variations in brackets, support pins
and shape and arrangement of apertures are possible beyond those
illustrated.
To use the shelf support bracket 90c shown in FIGS. 11 and 12, two
bracket support pins 98 are required for each shelf support bracket
and are positioned a vertical distance apart determined by the
vertical spacing of the upper and lower shelf support bracket hooks
96c, 104. The poles 22 are arranged as described hereinbefore and
the upper shelf support bracket hook 96c is initially forced to
engage an upper bracket support pin 98. The lower shelf support
bracket hook 104 is then forced to engage a lower bracket support
pin 98 which, due to the distance between the centers of the hooks
96c and 104, causes the lower bracket support pin to be raised
within the aperture 52. The just-described arrangement of the
bracket support pins 98 ensures rigid support of the shelf support
bracket 90c by both the upper and lower bracket support pins. A
similar shelf support bracket 90c is attached at a corresponding
vertical location on an adjacent pole 22 and a shelf 24c having
coves 102 at either end thereof is placed so as to have the coves
engage the flanges 94c of the respective shelf support brackets
90c.
Cabinets 26, chests of drawers 28, or other like articles of
furniture are attached by securing mounting strips 106 to the sides
thereof and engaging hooks 108 thereof with correspondingly placed
bracket support pins 98 within appropriate apertures of properly
spaced and secured poles 22.
Light bar 30 which is shown supporting incandescent bulbs 118, may
also support fluorescent bulbs (not shown) or other devices. In any
event, the light bar 30 and associated structure is supported by
the adjustable pole support system 20 by the use of mounting
bracket strips 114, the hooks 116 of which engage properly placed
bracket support pins 98.
With the incandescent lights 118, as with other electric or
electronic apparatus (not shown) electrical connection to a power
source is required. The necessary wiring for such apparatus may be
passed through appropriate openings in the mounting plates, for
example the opening 128 in mounting strip 114 (see FIG. 15), and
led through one of the apertures 52 to be carried within a front or
rear channel 48 or 50. The wiring may then exit from the channel 48
or 50 through an aperture 52 at or near the bottom of the rear of
the pole 22. The front and rear channels thus function as
convenient conduits for any required electrical connections.
To conceal any included wiring, as well as the apertures 52, the
channel caps 54, 56 may be snapped in place on the pole 22 thereby
decorating the front and rear channels 48, 50 as well.
Additionally, portions of channel caps 54, 56 may be positioned
between unoccupied vertical portions of right and left channels as
the channel openings of all channels are substantially the same,
thereby providing a finished appearance to the completed system. In
addition, the left and right channels 44a, 44b of the first and
last poles 22 of an assembled system can be completely covered with
channel caps.
Among the many variations possible which are considered to be
within the scope of the present invention would be the use of a
generally U-shaped support bar 130 (see FIGS. 16 to 19) which may
be used for a variety of functions to be described.
The bar 130 includes a central longitudinally extending top leg 132
and front and rear longitudinally extending legs 134, 136 extending
perpendicularly downward therefrom (see FIGS. 16 and 17). A support
bar hook 138, of a width approximating the width between side walls
32, 34 of a pole 22 extends downwardly from the central leg 132 in
the same direction therefrom as the front and rear legs 134, 136.
The support bar hook 138 is adapted to fit over a pin 98 supported
by the pole 22 with a similar support bar hook 138 appearing on the
opposite end of the support bar 130 (not shown) to support the bar
between two poles 22.
A table 140, or the like (see FIGS. 16 and 17), may have one end
thereof supported on the top of the central leg 132 of the support
bar 130 and extend between the poles 22 supporting the supporting
bar 130. The distal end of the table 140 may be supported by a
support leg (not shown). For added stability, the table 140 may be
secured to the support bar 130 by fastening means such as the screw
142 inserted therein through an opening 144 in the central leg 132
of the support bar 130.
Alternately, a support bar 130a may be provided (see FIGS. 18 and
19) which is similar to the support bar 130, except that the hook
138a thereof is bent in the opposite direction from the front and
rear legs 134a, 136a with respect to the central leg 132a. The
support bar 130a is mounted with the hook 138a thereof over a pin
98 supported by a pole 22. When mounted in this position, the
central leg 132a is usable as a bottom support and a panel 146 of a
thickness approximating the distance between the front and rear
legs 134a, 136a is supportable by the support bar 130a within the
U-shaped channel formed by the front, central, and rear legs 134a,
132a, 136a.
In a like manner, a support bar 130 may be used to secure the upper
portion of the panel 146 within the U-shaped channel therein, as
shown in FIGS. 18 and 19. Here again, fastening means such as a
screw 142 or the like may be used to provide secure support of the
panel 146 by the support bars 130, 130a by being inserted through
openings 144, 144a therein. The support bars 130, 130a extend
completely between two poles 22 and thus completely support a panel
146 therebetween useful as, for example, a chalk board or display
board.
As yet another variation of the present invention, a generally
cylindrical support bar 148 (see FIG. 20) may be provided with a
support bar hook 150 at each of its outer ends. The support bar 148
is of a length to be supported upon pins 98 of adjacent poles 22.
The cylindrical support bar 148 may be utilized in much the same
manner as the support bars 130, 130a described hereinbefore if the
upper and lower portion thereof are open. Alternately, in
commercial applications, the cylindrical support bar 148 may be
used for the display of merchandise on hangers or other supports,
thus permitting easy manipulation in combination with firm support
of the merchandise hangers.
Also, a mounting bracket strip 106a (see FIG. 21) is considered
within the scope of the invention. The mounting bracket strip 106a
is similar to the mounting bracket strip 106 (see FIGS. 13 and 14),
but includes an additional lower support flange 152 to aid in
positioning the cabinet 26 or chest of drawers 28 which is mounted
thereby.
Naturally, there are other variations considered to be within the
scope of the present invention, which have not been shown, such as
the adoption of channels 44a, 44b, 48 or 50 which are other than
orthogonal. For example, triangular channels could be used with
similar triangular shaped shelf support bracket hooks 96. Further,
various combinations of shapes of hooks and shapes of channels
would function to provide the necessary resistance to torsional
forces, though the presently illustrated combination is
preferred.
As will be readily apparent to those skilled in the art, the
invention may be used in other specific forms without departing
from its spirit or essential characteristics. For example, the
presently illustrated pole 22 can be made and sold with the
substantially identical sections 22a, 22b spaced and apart from one
another. The sections may then either be fastened together by upper
and lower fastening means, auxiliary fastening means between the
top and the bottom thereof, or may be used singly with articles
being supported from a single pole at one or a multitude of levels.
The present embodiment is, therefore, to be considered as
illustrative and not restrictive, the scope of the invention being
indicated by the claims rather than by the foregoing description,
and all changes which come within the meaning and range of
equivalence of the claims are therefore intended to be embraced
therein.
