Description
BACKGROUND OF THE INVENTION
This invention relates to changeable copyboards and in particular
to hanging devices for detachably mounting various indicia bearing
elements on the copyboard.
Conventional copyboards or displays containing changeable
characters are often used at various establishments such as
theaters, motels, restaurants, supermarkets, etc. Such copyboards
normally include a number of parallel, horizontal hanger bars or
tracks mounted in spacially separated, vertical positions on the
copyboard and with the individual changeable characters normally
detachably mounted between two adjacent hanger bars. Recently, it
has been desirable to mount other indicia bearing display members,
such as panels containing pictorial displays onto the standard
hanger bars forming the copyboard background.
However, such pictorial displays are normally much larger in
overall dimensions than the changeable characters, and are thus
conventionally placed on large panels which extend over a number of
hanger bars on the copyboard background. Since the pictorial
display panel is usually hung by providing slots in the vicinity of
the top and bottom of the panel frame for engagement with the
hanger bars, if the hanger bars are mounted slightly off horizontal
alignment, the location of the slots may not coincide with the
position of the top and bottom hanger bars making panel hanging
difficult if not impossible. In some instances, while the pictorial
panel may be hung, it will not be aligned on the copyboard, and
instead will be noticeably tilted.
Additionally, since there are a number of different types of hanger
bars or tracks currently in use, it is desirable to mount the new
type of pictorial display panels onto any of such copyboard
backgrounds. Examples of the variety of copyboard backgrounds are
shown for instance in U.S. Pat. Nos. 2,607,146; 2,633,652;
3,274,719; 3,274,720; 3,142,124; 3,258,869; 3,298,123; 3,531,884;
3,532,317 and 3,574,964, and in various patents cited thereiin,
many of which are repetitive of the above. Presently, there exists
not only the problem of matching the hanger bars with the mounting
slots in the pictorial panel, but the additional problem of
mounting the panels in the desired position and providing some
means for position adjustment so as to enable proper alignment and
use of the panel on at least some of the currently available
copyboard backgrounds.
SUMMARY OF THE INVENTION
Therefore, in accordance with the principles of the present
invention, there is provided a hanging device adjustably mountable
on an indicia bearing member, such as a pictorial display panel for
securably hanging the panel to a copyboard background, with the
position of the panel being adjustable on the background so as to
afford desired alignment therewith. Additionally, in accordance
with another aspect of the invention, there is provided a
reversible hanging device so that the pictorial display panel can
be hung on any one of the several currently available hanger bars
or tracks of the particular copyboard background.

DETAILED DESCRIPTION
Referring now to FIG. 1, there is illustrated a standard changeable
copyboard display 10 as used in a theater marquee and having a
number of substantially parallel, horizontal hanger bars or tracks
12 securely mounted thereto and forming the copyboard background.
Changeable indicia bearing members, such as the changeable
characters 14 extend between and are normally mounted to two
adjacent parallel hanger bars.
Any of a variety of hanger bars 12 are currently in use with
corresponding changeable characters 14 so that the characters can
be readily mounted and changed when desired on the copyboard
background.
As shown in FIG. 1, a pictorial display panel 16 is also mounted to
the copyboard background. The panel 16 is formed of a lightweight,
transparent plastic material to which is taped, cemented, or
otherwise attached a pictorial display sheet 17 (see FIGS. 2, 4,
5). At least two reversible hanging devices 18 are provided on
opposite flange sides of pictorial display panel 16 for mounting
the panel on the copyboard. The present invention is particularly
concerned with providing a reversible hanging device for pictorial
display panels such that the mounting position is adjustable and
can be accomplished on any of the hanger bars or tracks 12
currently in use.
Referring now to FIGS. 2-4, there is illustrated one embodiment of
a hanging device in accordance with the principles of the present
invention adjustably mounted on opposite side flanges of a
pictorial display panel for mounting the panel on an angled hanger
bar 20. The hanging device 18 comprises a block of resilient
material having an H-shaped cross section as shown for instance in
FIGS. 3 and 4. An intermediate web 22 generally divides the block
into two sections--one for receiving a side flange such as flange
24 of the panel 16 and the other for mounting on a copyboard
background such as the angled hanger bar 20. A pair of legs 26, 28
extend from the intermediate web 22 on one side of the hanging
device 18 with an open space between the legs to define a receiving
portion. As illustrated in FIGS. 3 and 4, one of the side flanges
24 of the panel 16 can be inserted into the receiving portion
between legs 26 and 28. Two or more threaded apertures 30 are
provided through the legs 26 and 28 and threaded fastening members
32 are insertable into the threaded apertures for securely
attaching the hanging device 18 to the pictorial display panel
16.
As shown in FIG. 1, the panel 16 is of generally rectangular
outline and is positioned on the copyboard background with the
shorter side extending across a number of the hanger bars 12. While
only a top and bottom hanging device have been illustrated as
attached to the panel 16, three or more of such devices can be
used, depending of course on the size of the panel and the various
other factors such as wind conditions, etc., encountered. Whereas
in the past each panel 16 incorporated a slot within its opposite
side flanges such as flanges 24 so that the panel was in effect
custom made for the particular copyboard background, the hanging
device 18 can readily be adjusted on the side flanges to any
position required. After adjustment of the hanging device to the
proper desired position, the fastening members 32 are tightened so
as to securely attach the hanging devices to the panel.
It is advisable that the panel 16, and particularly the flanges 24
be formed of a resilient plastic material which provides
flexibility, durability and compressibility. Compressibility is
especially desired to insure secure attachment of the hanging
devices. Particularly if the fastening members 32 are formed of
nylon, the members 32 can compress directly into the flanges 24 so
as to provide exceptional holding power. Thus, proper alignment of
the panel 16 on the copyboard 10 is readily provided with the
hanging device 18 of the present invention.
The hanging device 18 also includes another pair of legs 34 and 36
extending from the intermediate web portion 22 in a direction
opposite to that of the legs 26, 28. Each of the legs 34, 36
includes a generally V-shaped slot 38 extending from a closed end
40 adjacent the intermediate web 22 and opening outwardly along the
legs towards the leg ends 42. The V-slots 38 are shaped so as to
accommodate in a wedged locking engagement an angled hanger bar 20
generally in use and as shown for instance in U.S. Pat. No.
3,274,720.
In use, the desired number of hanging devices 18 are loosely
attached to the panel side flanges 24 and the panel 16 hung on the
copyboard 10. After proper placement and alignment of the panel 16
are attained, the threaded fastening members 32 are tightened to
securely attach the hanging device to the panel.
Referring to FIG. 5, there is illustrated another aspect of the
invention, wherein the hanging device 18 can be utilized for
hanging display members on another type of hanger bar or track
currently in use. As noted most clearly in FIGS. 2 and 3, the legs
34, 36 each includes at least two threaded apertures 44. Also, as
shown in FIGS. 3 and 4, there is an open space provided between the
legs 34 and 36 extending from the intermediate web 22 to the leg
ends 42 for defining an alternative receiving portion for mounting
display members to the hanging device 18.
Thus, FIG. 5 illustrates an indicia bearing member such as a
pictorial display panel 16 having opposite side flanges 34 one of
which is inserted between the legs 34 and 36 for securely mounting
thereto by means of the threaded fastening members 32. A suitably
shaped slot 46 is provided in the legs 26 and 28 for hanging the
panel onto an alternative hanger bar 48 of copyboard 50. The hanger
bar or track 54 is an alternative type of hanging element currently
in use for hanging changeable characters thereto. Thus, simply by
reversing the hanging device 18 from the position shown in FIGS. 2,
3 and 4 to that shown in FIG. 5, the same hanging device can be
utilized for mounting onto both the angled tracks and the T or L
shaped tracks which are currently in use. In either instance, the
hanging device 18 is readily adjustable on the panel 16 so that
proper placement and alignment of the panel on the particular
copyboard can readily be accomplished.
FIGS. 6 and 7 show alternative means for mounting the hanging
device 18 to the panels 16. As shown in FIG. 6, a series of grooves
50 are provided in opposite side flanges 52 of an indicia bearing
member such as panel 54, so that the grooves 50 alternate with a
smooth surface 56. The hanging device 18 is then adjusted on the
side flange 52 until proper placement and alignment of the panel 54
is achieved on the particular copyboard. The threaded fastening
members 32 are then tightened so as to engage the respective
grooves 50.
FIG. 7 illustrates another alternative mounting arrangement wherein
a series of cavities 58 are provided in a side flange 60 of indicia
bearing member such as panel 62. The hanging device 18 can be
attached to the panel by tightening the fastening members 32 until
they securely engage the cavities 58 after suitable adjustment for
proper panel alignment on the copyboard background.
It is to be understood that although the hanging device 18 has been
illustrated herein in connection with a pictorial display panel 16,
this is by way of example only, and the hanging device can as well
be applied to other indicia bearing members, such as the changeable
characters 14, and particularly to those changeable characters 15
(see FIG. 1) which extend over more than two hanger bars or tracks
on the copyboard background.
The foregoing detailed description has been given for clearness of
understanding only and no unnecessary limitations should be
understood therefrom as modifications will be obvious to those
skilled in the art.
