Description
BACKGROUND OF THE INVENTION
This application pertains to the art of wall assemblies, and more
particularly to assemblies of the type wherein modular structural
units are hung on walls assembled from a plurality of panels.
In previous assemblies of the type described, separate heavy gauge
vertical posts are required between the panels for hanging
structural units. The need for heavy structural posts makes the
assembly more expensive.
Previous assemblies of the type described often have the mounting
member slots visible and this presents an unsightly appearance.
Previous assemblies of the type described have also used structural
units having complicated hanging arrangements for hanging the
structural units to the mounting members.
SUMMARY OF THE INVENTION
An assembly of the type described includes substantially
rectangular panels formed of spaced-apart light gauge sheet metal
faces. The sheet metal faces are bent, folded and overlapped at
their opposite edges to define reinforcing and mounting panel
edges. With such an arrangement, heavy gauge structural posts are
not required and longitudinally-spaced mounting member slots can be
provided directly in the panel edges.
In accordance of another aspect of the invention, a pair of panels
are positioned with mounting edges thereon facing one another in
spaced-apart relationship. A relatively light gauge structural post
is positioned between the panel mounting edges. Elastomeric gasket
members are positioned between the post and the panel mounting
edges, and include gasket flanges overlying the
longitudinally-spaced slots. The gaskets also provide a sound
barrier to seal the joints between adjacent panels.
In accordance with another aspect of the invention, a structural
unit for hanging to the wall assembly includes a rear sheet metal
panel having opposite side flanges bent rearwardly to define
securing flanges. The upper edge of the rear panel is bent
rearwardly in the same direction as the securing flanges to form an
integral mounting hook. Side walls are secured to the securing
flanges and a bottom panel is secured to the side walls. In a
preferred arrangement, the bottom edge of the rear panel is bent
rearwardly in the same direction as the mounting hook and securing
flanges to define an assembly flange. The bottom panel has a rear
edge reversely bent to form an assembly hook. The assembly flange
and assembly hook are interdigitated for locking the bottom panel
to the rear panel.
In accordance with another aspect of the invention, an elongated
protector strip is positioned between the mounting members and the
mounting hook on a structural unit for protecting the panel outer
surfaces against damage by the mounting hook.
In accordance with another aspect of the invention, a load bar
assembly is provided for hanging onto the mounting members and
supporting smaller structural units which do not extend completely
across a panel. The load bar assembly also distributes the load
from the smaller structural units and transfers the load to the
panel edges. The load bar has opposite longitudinal edges bent into
load bar hooks. Both longitudinal edges of the load bar assembly
have substantially the same cross-sectional configuration so that
the load bar assembly may be hung from the mounting members in
either of two reversed positions.
In accordance with still another aspect of the invention, improved
mounting members are provided for attachment to the panel edges to
hang structural units thereon. The mounting members include a
mounting flange having longitudinally-spaced locking tabs
receivable in the slots in the panel edges. The mounting member
includes a web extending laterally from the mounting flange. The
mounting member web has a spacer flange extending outwardly
therefrom in the same direction as the mounting flange. With the
locking tabs received in the slots, the spacer flange engages a
side portion of the panel outer surface to locate the web in
outwardly-spaced substantially parallel relationship to a side edge
portion of the panel outer surface. The mounting member has upper
hooking means for reception in a mounting hook pocket on the
structural units.
It is a principal object of the present invention to provide an
improved structural panel having integral strengthened panel
edges.
It is also an object of the present invention to provide an
improved arrangement for connecting adjacent panel edges.
It is a further object of the present invention to provide improved
wall-hanging structural units.
It is an additional object of the present invention to provide
improved mounting members for hanging structural units to wall
assemblies.
It is another object of the present invention to provide an
improved load bar assembly for hanging relatively narrow structural
units to wall assemblies and distributing the load of the
structural units.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein the showings are for
purposes of illustrating preferred embodiments of the invention
only and not for purposes of limiting same, FIG. 1 shows a
substantially vertical wall assembly constructed from a plurality
of vertically-positioned generally rectangular panels A. Panels A
have opposite side edges B which also define panel mounting edges.
Vertical cylindrical posts C are positioned between panel edges B
on adjacent panels for holding adjacent panels A together and in a
substantially vertical position.
In one arrangement, panel edges B have longitudinally-spaced
vertically-elongated slots 12 therein for attaching mounting
members D to panel edges B. Vertically-elongated elastomeric gasket
members E are positioned between posts C and panel edges B. Gaskets
E include gasket flange portions overlying slots 12. A structural
unit F has an upper rear mounting hook G engageable over the upper
portions of mounting members D for hanging structural unit F on
panel A. Structural unit F may take many different forms, such as
an open-topped box, a shelf, a cabinet, or a drawer unit. The
structural unit may also be defined by chalk board or bulletin
board.
In a preferred arrangement, an elongated non-metallic protector
strip H is positioned between the upper portions of mounting
members D and structural unit mounting hook G for protecting the
outer surfaces of panels A against damage.
With reference to FIG. 10, panel edge portions B are shown
positioned in spaced-apart facing relationship with cylindrical
posts C interposed therebetween. Each of panels A is constructed
from a pair of substantially parallel spaced-apart light gauge
sheet metal faces I having substantially rectangular plain central
portions 16 and opposite edge portions 18. The space between
central portions 16 of faces I may be filled with a honeycomb
structure or any other suitable filling material. Each edge portion
18 of faces I is bent inwardly as at 20 to define a web portion
extending the full length of metal sheets I. Web portions 20 extend
substantially perpendicular to central portions 16 of faces I. End
portions 18 are bent outwardly from webs 20 and reversely folded to
define a main folded portion 22 and a terminal folded portion 24.
Main folded portion 22 extends outwardly from web 20 substantially
perpendicular thereto. Terminal folded portion 24 extends outwardly
from main folded portion 22 and is inclined back toward web 20.
Terminal folded portions 24 terminate at terminal folded portion
edges 26 which are spaced outwardly from webs 20 to define mounting
spaces 30. Longitudinally-spaced slots 12 are formed through main
folded portions 22 and are in alignment with mounting spaces 30.
The edge portions of metal sheets I are bent outwardly and then
back to form main and terminal folded portions 22 and 24, and are
then bent inwardly to define terminal flanges 32 and 32'.
Terminal flanges 32 extend in alignment with webs 20, while
terminal flanges 32' are offset from webs 20 by an amount
substantially equal to the thickness of flanges 32 or 32'. Flanges
32 and 32' can then be overlapped and secured together. Webs 20 and
flanges 32 will be in alignment with one another. The offset of
flange 32' will also allow terminal end edges 26 of terminal folded
portions 24 to lie in a common vertical plane extending
perpendicular to panels A. Each face I has a flange 32 along one
side edge thereof, and a flange 32' along the opposite side edge
thereof.
With the arrangement described, a pair of faces I having the bent
and folded end configuration described are reversely positioned
with central portions 16 thereof spaced apart, and with terminal
flanges 32 and 32' thereof overlapping one another. Overlapping
terminal flanges 32 and 32' are then secured together as by a
plurality of longitudinally-spaced sheet metal screws 36.
Obviously, overlapping terminal flanges 32 could also be secured
together by other fasteners, such as rivets, or welded
together.
The described bending and folding of sheet metal faces I, and their
manner of securement together, provides opposite panel edges B with
a generally channel-shaped cross-sectional configuration. The
channel-shaped cross-sectional configuration includes spaced-apart
longitudinally extending channel legs defined by main folded
portions 22 and a channel base defined by overlapping terminal
flanges 32. With such an arrangement, opposite panel edges B are
very strong and capable of serving as structural supporting members
themselves. This makes it unnecessary to provide a heavy gauge post
C. This also eliminates the need for securing additional heavy
gauge channels or the like to the opposite edges of panels A. With
the arrangement described, outwardly opening channel spaces 40 are
defined between main folded portions 22 on each panel edge B. At
least a portion of post C extends into channel spaces 40 between
main folded portions 22 for preventing lateral displacement of
panels A relative to posts C.
In accordance with a preferred arrangement, elastomeric gasket
members E are positioned between post C and panel edges B. Gaskets
E may be formed of natural or neoprene rubber, or any suitable
synthetic plastic material, such as polyvinylchloride compounded to
be relatively soft and flexible. Gaskets E preferably extend the
full length of panel edges B. Gaskets E include a central arcuate
portion 42 spanning channel spaces 40. Gaskets E have inclined
flange portions 44 overlying terminal folded portions 24. Gaskets E
have terminal gasket flanges 46 which extend over terminal ends 26
of terminal folded portions 24 and substantially span across
mounting spaces 30 toward webs 20 for overlying and concealing
slots 12 in main folded portions 22. Gaskets E may be compounded in
any desirable color for complementing the decorative surface color
provided on metal sheets I and posts C.
Any one of terminal gasket flanges 46 may be deformed outwardly or
inwardly for attaching a mounting member D to a panel edge B.
Mounting members D may be positioned on either or both sides of
panels A. Gaskets E provide a decorative covering which hides
vertical slots 12 and presents a pleasing appearance. Gaskets E
also provide a sound barrier to prevent or minimize transmission of
sound from one side of panels A to the other through the joint
portions therebetween.
With reference to FIG. 3, one arrangement for structural unit F is
shown. Structural unit F is specifically shown as an open-top file
box or the like. However, it will be recognized that the structural
unit may also be formed as a shelf or cabinet unit having an open
front, or having doors at the front or top. Structural unit F
includes substantially rectangular metal rear panel J having
opposite side edges bent rearwardly to define securing flanges 52.
The upper edge portion of rear panel J is bent to form mounting
hook G. The upper edge of rear panel J is first bent rearwardly to
form a first mounting hook flange portion 54 extending rearwardly
from panel J in the same direction as securing flanges 52 and
having substantially the same width as securing flanges 52.
Securing flanges 52 and mounting hook flange 54 extend
substantially perpendicular to plain rectangular main portion 56 of
rear panel J. The upper edge of rear panel J is then bent upwardly
to form a second hook flange 58 extending substantially
perpendicular to first mounting hook flange 54. The upper edge of
rear panel J is then bent rearwardly again to define a third
mounting hook flange 60 extending substantially parallel to first
mounting hook flange 54 and spaced above first mounting hook flange
54. The upper edge portion of rear panel J is then bent downwardly
from third mounting hook flanges 60 to define a mounting hook
terminal flange 62 extending downwardly from third flange 60 and
extending substantially parallel to second mounting hook flange 58.
Mounting hook G preferably extends substantially the full length of
rear panel J. The bottom portion of rear panel J is bent rearwardly
in the same direction as securing flanges 52 to define an assembly
flange 66 extending substantially the full length of panel J.
A bottom substantially rectangular sheet metal panel K is provided
for structural unit F. The rear edge portion of bottom panel K is
reversely bent to define an assembly hook having vertically-spaced
assembly hook flanges 68 and 70 defining an assembly hook pocket 72
therebetween. As shown in FIG. 4, the assembly hook and assembly
flange are interdigitated for securing bottom panel K to rear panel
J. That is, assembly flange 66 is tightly received in assembly hook
pocket 72 between assembly hook flanges 68 and 70 in the manner
shown in FIG. 4.
Bottom panel K may be bent intermediate its front and rear edges to
provide a longitudinally extending reinforcement rib 74 which
stiffens panel K against deformation. Panel K has downwardly bent
side edge securing flanges 76 extending substantially perpendicular
to bottom panel K. Bottom panel K also has a downwardly bent front
securing flange 78 extending substantially perpendicular to panel
K. Securing flanges 52 and 76 have suitable longitudinally-spaced
holes therethrough generally shown by numeral 80 for receiving
screws 81 which are threaded into suitable holes in side walls 82.
Side walls 82 may be formed of any suitable material, such as
boards, plywood, particle board, or synthetic plastic material. The
described arrangement securely attaches side walls 82 to rear panel
J and bottom panel K. Resilient bumpers as at 84 in FIG. 3 may be
attached to the rear vertical edges of side walls 82 for bearing
against an outer surface of panel A when structural unit F is hung
on mounting members D. Structural unit F may have a front wall
defined by a substantially rectangular panel 86. The opposite side
edges of panel 86 may have elongated recesses 88 formed therein for
receiving bracket members 90. Screws or the like may be used for
securing bracket members 90 within recesses 88, with the outer
surfaces of brackets 90 substantially flush with the outer opposite
side edges of panel 86. Screws, as at 92, may be threaded into the
inside edge surfaces of side walls 82 and have enlarged heads
receivable in keyhole slots in brackets 90 for securing front panel
86 to side walls 82. It is obvious that many known arrangements may
be provided for securing front panel 86 to side walls 82. Front
securing flange 78 on bottom panel K has a plurality of
longitudinally-spaced holes therethrough for receiving screws which
thread into the inside bottom portion of front panel 86.
In accordance with one arrangement, elongated nonmetallic protector
strip H may be extruded of any suitable synthetic plastic material
or the like compounded to be somewhat rigid. For example, strip H
may be formed of polyvinylchloride compounded to be somewhat rigid.
Protector strip H has a cross-sectional configuration defined by a
pair of reversely positioned generally U-shaped portions 102 and
104. Inverted U-shaped portion 104 has a downwardly facing opening
106 and is substantially larger than U-shaped portion 102 which has
an upwardly facing opening 108. Inverted U-shaped portion 104 is
dimensioned for snug reception within downwardly facing hook pocket
112 in mounting hook G on rear panel J. That is, the outer surfaces
of inverted U-shaped portion 104 on protector strip H are in snug
engagement with the inner surfaces on mounting hook flanges 58, 60
and 62. Terminal mounting hook flange 62 is snugly received within
elongated upwardly facing opening 108 on U-shaped portion 102. That
is, the opposite inner surfaces in upwardly opening pocket 108 are
in snug engagement with the opposite surfaces of terminal mounting
hook 62. With such an arrangement, mounting and dismounting of
structural unit F will result in only protector strip H contacting
panels A so that the outer surfaces thereof will not be damaged or
scratched.
In accordance with one arrangement, mounting members D may be
constructed of relatively heavy gauge metal and include an
elongated upright mounting flange 116 having an inner mounting
flange edge 118. Inner mounting flange edge has a plurality of
longitudinally-spaced mounting hook tabs 120, 122 and 123. Mounting
hook tabs 120 and 122 having hooking portions extending generally
downwardly, while mounting hook tab 123 has an outer hooking
portion extending generally upwardly. Mounting member D includes a
central web portion 126 extending substantially perpendicular to
mounting flange 116. Web portion 126 has a spacer flange 128
extending inwardly from the lower edge thereof. In the arrangement
described, it is obvious that main folded portions 22 are spaced
inwardly from the outer surfaces of central portions 16 on sheet
metal panels I. Uppermost mounting hook tab 123 is first positioned
through one of slots 12. Mounting member D is then moved upwardly
as far as it will go and its lower end is swung toward panel A
until mounting hook tabs 120 and 122 extend through others of slots
12. With mounting hook tab 123 upwardly in contact with a top edge
of one of slots 12, mounting hook tabs 120 and 122 will just clear
the bottom edges of other slots for reception therethrough.
Mounting member D is then released and drops down slightly so that
mounting hook tabs 120 and 122 are locked behind bottom edges of
certain slots 12, while tab 123 is locked behind an upper edge of
its slot 12.
Mounting flange 116 is dimensioned to have a width greater than
spacer flange 128 so that when mounting member D is mounted to
slots 12 in the manner described, spacer flange 128 will bear
against a side outer surface portion of panel A with web portion
126 extending substantially parallel to the outer surface of panel
A. Mounting members D have upper hooking portions for reception in
mounting hook pocket 12 on a structural unit F. In one arrangement,
the upper hooking portion is defined by hooking flange 130
extending inwardly from the upper edge of web portion 126
substantially perpendicular thereto. Hooking flange 130 has a width
less than the width of spacer flange 128 so that terminal hooking
flange edge 132 is spaced outwardly from the outer surface of panel
A. Hooking flange edge 132 is spaced outwardly from the outer
surface of panel A a distance which is just sufficient for
receiving U-shaped portion 102 on protector strip H. That is, the
opposite outer surfaces on U-shaped portion 102 are spaced-apart
substantially the same distance or slightly less than the distance
from mounting flange edge 132 to the outer surface of panel A when
mounting members D are attached to panels A in the manner
described. Structural units F may then be hung from mounting
members D by use of integral mounting hooks G on structural units
F. In the preferred arrangement, protector strip H is first mounted
onto mounting hook G before structural unit F is hung onto mounting
members D.
In accordance with another aspect of the invention, a load bar
assembly M in FIG. 2A is provided for securing structural units N
to a wall assembly of the same type described with respect to FIGS.
1 and 10. In this arrangement, mounting members P are provided.
Load bar assembly M comprises a substantially rectangular sheet
metal panel having opposite side edges 140 and spaced-apart
longitudinal edges extending substantially perpendicular to side
edges 140. Load bar assembly M includes a substantially rectangular
central portion 142 having outer and inner surfaces. The opposite
longitudinal edges of panel 142 are bent to have substantially the
same cross-sectional configuration. The configurations at the
opposite longitudinal edges are simply inverted relative to one
another. The opposite longitudinal edges of load bar assembly M are
bent to define load bar mounting hooks R. Each mounting hook R
includes a first web 144 extending toward the inner surface of
panel 142 substantially perpendicular to panel 142. A second web
146 extends downwardly from first web 144 in outwardly-spaced
overlying relationship to the inner surface of panel 142 and
substantially parallel to panel 142. A third web 148 extends
outwardly from second web 146 substantially parallel to first web
144 and spaced inwardly therefrom. Load bar mounting hooks R
terminate in terminal web 150 extending perpendicular to third web
148 and parallel to second web 146. Terminal web 150 is spaced
outwardly from the inner surface of panel 142 in overlying
relationship thereto.
With the arrangement described, load bar assembly M may be hung
from mounting members P in either of two inverted positions. The
load bar mounting hook R which is located along the bottom edge of
load bar assembly M provides a spacer for engaging mounting members
P and spacing panel 142 outwardly from the outer surface of a panel
A in substantially parallel relationship thereto. A pair of
spaced-apart elongated reinforcing metal beams 154 are spot welded
to the inner surface of panel 142. Reinforcing beams 154 extend in
a direction between opposite side edges 140 of panel 142.
Reinforcing beams 154 have opposite ends 156 spaced inwardly from
opposite side edges 140 by a distance generally the same as the
total width of mounting members P.
Load bar assembly M may be hung on mounting members P when
structural units N have a total width less than the distance
between opposite panel edges B. Therefore, a plurality of
relatively short structural units may be hung from load bar
assembly M. Load bar assembly M will distribute the force or weight
of the structural units and carry the load over to reinforced
opposite panel edges B so that deformation of thin gauge sheet
metal sheets I will not occur. Structural unit N may be assembled
in the same manner as described with respect to structural F in
FIG. 3, the only difference being that structural unit N has a
width substantially less than the width of structural unit F.
Structural unit N, or other structural units, may be in the form of
shelves, drawers and cabinets for suspension on load bar assembly
M.
Mounting members P are adapted to be mounted on opposite panel
edges B in the same manner as described with respect to mounting
members D. Mounting members P include a mounting flange 160 having
a mounting flange inner edge 162 with longitudinally-spaced tab
hooks 164, 166 and 168 extending outwardly therefrom. Tab hooks
164, 166 and 169 correspond with tab hooks 120, 122 and 123 on
mounting members D. Therefore, mounting members P are secured to
panel edges B with the described tabs received in elongated slots
12 in the same manner as described with respect to mounting members
D. Mounting members P have web portions 170 extending inwardly from
mounting flange 160. A spacer flange 172 extends inwardly from the
opposite edge of web portion 170. Like the arrangement described
with respect to mounting members D, mounting flange 160 has a width
greater than the width of spacer flange 172. With tabs 164, 166 and
168 received in slots 12, the inner edge of spacer flange 172
engages the outer side surface of panel A for spacing web portion
170 outwardly therefrom in parallel relationship thereto. The upper
portion of mounting members P have upwardly facing hooking portions
thereon for cooperation with load bar mounting hook R. Mounting
flange 160 has a top edge 176, and web 170 has an upper hooking
projection 178 extending upwardly above mounting flange top edge
176. Adjacent web portion 170, mounting flange 160 has a hooking
projection 180 integral with projection 178 and extending
substantially perpendicular thereto. In one arrangement, mounting
flange 160 is deformed inwardly as at a perpendicular shoulder
portion 182. Load bar mounting hook R is hung onto the top portion
of mounting members P in the manner shown in FIG. 2B. The width of
hooking projection 180, from an inner edge of hooking projection
180 to the outer surface of hooking projection 178, is
substantially the same as the distance between the inner surface of
second web 146 and the inner surface of panel 142. The distance
from the inner edge of hooking projection 180 to the inner surface
of shoulder 182 is substantially the same as the distance between
the inner surface of second web 146 and the inner surface of
terminal web 150. With mounting members P assembled to the wall
assembly, the inner surface of shoulder 182 is spaced outwardly
from the outer surface of panel A a sufficient distance that
terminal web 150 on load bar mounting hook R can be received
between the inner surface of shoulder 182 and the outer surface of
panel A. The upper edge of spacer flange 172 is preferably cut-away
a sufficient distance that terminal web 150 will not contact spacer
flange 172. Protector strip H is assembled to mounting hook G on
structural unit N in the manner previously described. The distance
between the opposite inner surfaces of downwardly facing pocket 106
on protector strip H is substantially the same as the distance
between the outer surface of panel 142 and the outer surface of
second web 146. Therefore, strip H may be assembled to mounting
hook G and then hooked over load bar mounting hook R. Protector
strip H preferably has a length at least as great as the distance
between opposite side edges 140 of panel 142. Structural units N
may be hung in any desired position along load bar assembly M and
may be shifted relative to load bar assembly M.
FIGS. 5 and 6 show a shelf unit S having a substantially
rectangular sheet metal rear panel 186. Rear sheet metal panel 186
has opposite side edges bent rearwardly to form securing flanges
188. The upper edge portion of rear panel 186 is bent to form an
integral mounting hook G in the same manner as described with
respect to the mounting hook in FIG. 3. Protector strip H also
cooperates with mounting hook G on panel 186 in the same manner as
previously described. A rectangular top shelf board 190 has
longitudinally-spaced holes in the bottom edge portions thereof as
at 192 for receiving screws 92 having enlarged heads receivable in
keyhole slots of brackets 90 which are secured within recesses in
the upper edges of side boards 194 in the same manner as described
with respect to recesses 88 in front panel 86 of FIG. 3. Securing
flanges 188 have longitudinally-spaced holes therethrough for
receiving screws 196 which are threaded into the inner rear edge
portions of side boards 194. First flange 54 of mounting hook G may
also have a plurality of longitudinally-spaced openings
therethrough for receiving screws 198 which are threaded to the
bottom rear portion of shelf board 190. The top surface of shelf
board 190 will then be substantially flush with the top surface of
second mounting hook flange 60. Shelf unit S is then hung to
mounting members D, or onto load bar assembly M, in the same manner
as described with respect to hanging structural units F and N.
A pair of spaced-apart drawer slide members 202 of FIG. 7 may be
secured to the underside of shelf board 190 by screws 204 extending
into longitudinally-spaced holes 206 in the bottom surface of shelf
board 190. A drawer unit 210 may then have its opposite side edges
212 extending outwardly beyond its bottom opposite edges 214 for
slidable reception on drawer slides 202. Various other arrangements
for mounting drawers for hanging onto the wall assembly may also be
used.
FIGS. 8 and 9 show another structural unit T. Structural unit T is
substantially the same as structural unit F except for having a
different bottom panel. Rear sheet metal panel 220 of structural
unit T has opposite side edges bent rearwardly to define securing
flanges 222. The upper edge portion of rear sheet metal panel 220
is bent in the same manner as described with respect to panel J of
FIG. 3 to form an integral mounting hook G. Securing flanges 222
have longitudinally-spaced holes therethrough for receiving screws
224 which are threaded into the inner rear portions of sidewalls
226. A bottom panel board 228 has recesses 88 in the opposite side
edges thereof for receiving mounting brackets 90 having keyhole
slots therein for cooperation with enlarged heads on screws 92
attached to the inner surfaces of side walls 226 for mounting
sidewalls 226 to bottom panel board 228.
FIG. 11 shows another unit U having a sheet metal rear panel bent
to provide an integral mounting hook G in the same manner as
previously described. Structural unit U has opposite side walls 230
and a front wall 232. A cover 234 may be hingedly connected with
the rear upper portion of side walls 230 or with first flange 54 on
mounting hook G. Obviously, various other types of structural units
may also be provided. Each structural unit is common in that it
includes a rear sheet metal panel having an integral mounting hook
G formed thereon. Various types of shelves, cabinets, drawers and
boxed may be provided for hanging onto the wall assembly in the
manner described. Various other structural units, such as chalk
boards or bulletin boards, may also be hung from the wall assembly
in the same manner. In such arrangements, a small sheet metal panel
having an integral mounting hook G thereon would be secured to the
upper rear surface of the chalk board or bulletin board.
Although the invention has been shown and described with respect to
certain preferred arrangements, it is obvious that equivalent
alterations and modifications will occur to others skilled in the
art upon the reading and understanding of this specification. The
present invention includes all such equivalent alterations and
modifications, and is limited only by the scope of the claims.
