Description
BACKGROUND OF THE INVENTION
Vertically extending panels are employed for a variety of purposes.
For instance, such panels can be employed for displaying material;
also, the same can be used as a room divider, and in instances
where the surface of the panel has been formed as a chalkboard, the
same can be used in a classroom or wherever else desired in order
to be used as a convenient surface for displaying or projecting
informative matter thereon. As can be appreciated, such vertically
extending panels must necessarily be supported and retained in such
vertically extending position by suitable means usually engaging
with the bottom or sides of the panel. In instances where the panel
is of considerable width and height in relation to thickness, some
difficulty is experienced in providing for a proper support which
will retain the panel in its vertical upright position.
With the above in mind, it is the primary object of the invention
to provide a pair of elongated feet members designed to each engage
with a horizontally extending pin or pintle mounted on the
undersurface of the bottom wall of the panel and when so mounted,
the feet will extend outwardly from the front and rear walls of the
panel so as to retain the panel in its vertically extending
position. The engagement is made by manual hooking without the use
of tools. The load acceptance then positions the hooks on the pins
according to the load deflection on the shoulder of the foot.
A still further object of the invention is to provide each of a
pair of supporting feet for panels and the like with a relatively
wide load bearing surface which will engage with the undersurface
of a bracket having a pivot pin therebetween so as to more evenly
distribute the load factor imposed on the supporting feet and to
likewise form a more stable support for the panel.
A still further object of the invention is to provide casters or
glides at one end of each of the pairs of supporting feet so as to
enable the panel supported thereby to be easily transferred from
one place to another.
A still further object of the invention is to provide a bracket
means adapted to be secured to the undersurface of the bottom wall
of a panel, said bracket having a pin or pintle mounted thereon
which will engage with the hook end of each of the pairs of
supporting feet for maintaining the panel in its vertical
position.
Another object of the invention is to provide a bracket mounted on
the undersurface of the bottom wall of a panel which will function
as a support for the panel when it is not necessary to employ pairs
of supporting feet for maintaining the panel in its vertical
position for its intended purpose.
Another object of the invention is to provide a panel which may be
maintained in its vertical position by means of pairs of supporting
feet which may be readily assembled and disassembled and which
require a minimum of shipping and storage space.
A still further object of the invention is to provide pairs of
supporting feet for engagement with a suitable pin or pintle
secured to a bracket mounted on the undersurface of the bottom wall
of a panel and which will enable the support to be used in the
support of a panel of any width and a wide range of wall
thicknesses.

PREFERRED EMBODIMENTS OF THE INVENTION
Referring now to the drawings, there is shown therein at FIG. 1 a
panel 10 comprising a conventional framework consisting of a top,
bottom and side walls adapted to have contained therein a display
surface 11. It should be pointed out that while I will refer to a
panel having a display surface contained within the said framework,
the invention is not to be construed as being limited to the proper
support of a display panel. For instance, if the panel illustrated
generally at 10 is to be used as a room divider, the display
surface would be in the nature of a decorative surface contained
within the aforesaid framework, or if the panel is to be employed
to support a projection screen within the confines of the
aforementioned framework, a suitable projection screen would be
confined within the confines of the framework, and yet still, if
the panel is to be employed for supporting a blackboard, then a
suitable erasable surface would be mounted within the aforesaid
framework, etc. Also, while FIG. 1 shows but one side of the panel
having a display surface thereon, it is obvious that a similar or
dissimilar surface can be mounted within the aforesaid framework
for the panel and caused to be exhibited on the opposite side of
the assembly.
Referring now more particularly to FIGS. 2 and 3 of the drawings,
there is shown therein a bracket 12 formed of any suitable material
such as metal, plastic, etc. The bracket 12 is of a generally
rectangular shape and is adapted to be secured to the undersurface
13 of the framework for the panel 10. The bracket may be adhesively
secured to the undersurface 13 aforesaid or the same may be secured
thereto as by means of screws, bolts, etc. (not shown). The bracket
has a pair of depending walls 14 and 15 between which is mounted in
any known manner a pin or pintle 16 for a purpose to be more fully
described hereinafter.
Wall 15 of bracket 12 is provided at either end thereof with
internally threaded portions 17 and 18 formed in bosses 19 and 20.
When desired, externally threaded pads or feet 21 and 22 can be
secured to the said internally threaded portions 17 and 18 in
instances where it is not deemed necessary to employ the supporting
feet of the present invention to maintain the panel in its vertical
position. The drawings, particularly FIG. 1 thereof, show but a
pair of brackets 12 secured to the undersurface of the panel 10.
However, it is to be understood that as many brackets 12 will be
employed with any given panel so as to insure the proper
maintenance thereof in its vertical position, thereby enabling the
same to perform its intended function.
The supporting feet of the present invention comprise a pair of
elongated members 23 and 24 formed of any suitable material such as
metal, plastic, etc. As clearly shown in FIG. 4 of the drawings,
each of the elongated members 23 and 24 forming the feet of the
present invention are provided on the undersurface thereof with
shallows or voids 25 which can be formed therein at the time of
molding or casting of the elongated members. The ribs 26 extending
between the voids 25 serve as strengthening members for the feet 23
and 24 when the feet engage with the brackets 12 for supporting the
panel in a manner to be more full described hereinafter.
The elongated members or feet 23 and 24 are each provided at one
end thereof with a curved or hook portion 27 and 28 formed integral
with the remainder of the feet 23 and 24, and when the feet are
employed to support the panel 10, the hook members 27 and 28 engage
with the pintle 16 and are caused to rest thereon, as clearly shown
in FIG. 2 of the drawings. Referring now more particularly to FIGS.
3, 4 and 5, it will be seen that the end of the feet 23 and 24,
adjacent the aforementioned hook members 27 and 28, is formed of a
relatively flat surface 29 and 30 which will contact with the
relatively flat undersurface 31 of bracket 12. These cooperating
flat surfaces will more evenly distribute the load factor imposed
on the supporting feet thus providing for a more stable supporting
surface. Also, as seen in FIGS. 4 and 5 of the drawings, the
supporting feet 23 and 24 taper downwardly toward the floor or
other surface and terminate in floor-engaging flat surfaces 32 and
33.
Thus, there has been described a support for panels and the like
which consists of a pair of elongated members or feet constructed
as aforesaid and which are adapted to engage with pins or pintles
extending between brackets mounted on the undersurface of the
bottom wall of the panel. As can be clearly understood from the
drawings, the supporting feet are assembled with the panel as
aforesaid and when thus assembled, the feet extend both forwardly
and rearwardly of the panel so as to afford a reliable support for
the panel and the like.
Shown in FIGS. 7 and 8 of the drawings are modifications which may
be made to the floor-engaging end of the supporting feet. FIG. 7
shows a slide type caster 34. The glide 34 is of conventional
structure and comprises a slide surface 35 formed of steel,
plastic, etc. The glide 34 is mounted to the supporting feet 23 and
24 as by means of a swivelled bolt connection 36 or by any other
known means for pivotally securing the slide caster to the
supporting feet. FIG. 8 shows a slightly different type of
swivelled caster mounted to the end of the supporting feet. In this
modification, a sphere 37 is pivotally connected to the supporting
feet as by means of a swivelled bolt connection 38. Secured in any
known manner to the sphere 37 is an inner race 39 and mounted for
rotation thereon is an outer race 40. Disposed between the inner
and outer races 39 and 40 are conventional roller bearings (not
shown).
Thus, the structure shown in FIG. 7 of the drawings will enable a
supported panel to be easily moved from place to place with the
glide type caster permitting for the easy moving of the assembly
whereas the modification of FIG. 8 provides for an anti-friction
means for movement of the supported panel from one place to
another.
While I have illustrated and described the preferred embodiments of
my invention, it is to be understood that I do not limit myself to
the precise constructions herein disclosed and the right is
reserved to all changes and modifications coming within the scope
of the invention as defined in the appended claims.
