Description
BACKGROUND OF THE INVENTION
This invention relates to an illuminated display. It relates more
particularly to a display of this type which produces colored
patterns whose color and design constantly change in a random
fashion.
Kinetic display devices have wide application for attracting
potential customers' attention to store windows, shelf displays and
the like. There are various displays of this general type which are
currently in use. Some of these employ rotating colored discs,
flashing lights, and other kinetic elements to attract the eye.
Many of them are quite complex and expensive for the intended
application. On the other hand, other less costly display devices
do not produce the random design variations and color patterns
which most readily attract and hold the observer's attention.
Accordingly, this invention aims to provide an illuminated display
which produces a very wide variety of constantly changing,
random-colored patterns.
Another object of the invention is to provide illuminated display
apparatus which is relatively easy and inexpensive to make.
Yet another object of the invention is to provide illuminated
display apparatus which produces many different patterns with no
recognizable repetition thereof.
Still another object of the invention is to provide an illuminated
display whose pattern includes color shading and mixed colors
during different operating periods.
A further object of the invention is to provide an illuminated
display which is simple in nature, yet produces a lighting effect
for the observer which is very complex.
Other objects of the invention will in part be obvious and will in
part appear hereinafter.
The invention accordingly comprises the features of construction,
combination of elements and arrangement of parts which will be
exemplified in the construction hereinafter set forth, and the
scope of the invention will be indicated in the claims.
In general, the present display comprises a box-like housing having
a translucent front wall. A multiplicity of dividing walls are
arranged inside the housing generally perpendicular to the
translucent wall thereof. The dividing walls extend in various
directions for various distances so as to create within the housing
an array of compartments having different shapes and sizes.
A wheel is rotatively supported within the housing about an axis
generally perpendicular to the translucent housing wall. This wheel
also has a number of dividing walls which project outward toward
the walls within the housing. These dividing walls also define a
number of odd-shaped compartments on the front face of the
wheel.
Different colored lights are mounted on the wheel so that there is
at least one light in each compartment. The lights are all
connected by way of sliding contacts to an external power supply.
The wheel is rotated by means of a conventional electric motor
mounted on the housing.
When the lights are energized and the wheel is rotated, a
constantly changing color pattern is projected onto the translucent
wall of the housing. More particularly, different colored light
fills each compartment on the wheel. This light is projected into
the opposing compartments in the housing and appears on those areas
of the translucent housing wall bounded by the latter
compartments.
The wheel is constantly rotating so that the wheel compartments are
continually brought opposite different compartments in the housing.
Therefore, the light projected into a particular housing
compartment is constantly changing and may, in fact, comprise a
plurality of colors, depending upon the alignment of the two sets
of dividing walls.
The height of the dividing walls also contributes substantially to
the variety of color patterns obtainable from the present display.
This is because the walls produce a shadow effect which varies the
intensity of the colored light projected through the translucent
wall from the various housing compartments. In other words, as the
orientation of the wheel relative to the housing changes, the
angles of incidence on the various housing compartment walls of the
light emanating from a particular bulb on the wheel continually
change. Consequently, the amount of light reflected from these
walls through the translucent wall changes correspondingly, thereby
producing constantly changing gradations in color, intensity and
hue.
Even though the present display is constructed of simple,
relatively inexpensive parts, it produces a kinetic display which
is characterized by a vast range of color designs which constantly
change in a random way. Thus as a practical matter, the observer
never sees the same design more than once. For this reason, when
the display is placed in a store window or on a counter, it is able
to attract and hold the attention of even the most casual observer.
Consequently, it can function as a valuable advertising device as
well as an attractive piece of kinetic art.
BRIEF DESCRIPTION OF THE DRAWING
For a fuller understanding of the nature and objects of the
invention, reference should be had to the following detailed
description taken in connection with the accompanying drawing, in
which:
FIG. 1 is an isometric view of an illuminated display embodying the
principles of my invention;
FIG. 2 is an exploded perspective view showing the FIG. 1 display
in greater detail;
FIG. 3 is a side elevational view of the display with parts broken
away; and
FIG. 3A is an isometric view on a larger scale of the sliding
contacts used in the FIG. 1 display.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 of the drawing, the elements of my display are
contained in a box-like housing 10 having an enlarged base 12 for
stability. The walls of housing 10 are opaque except for the front
wall 14 which consists of a translucent sheet of glass or plastic
or frosted glass. The illuminated display shown generally at 16
which is produced by the subject apparatus is visible through
translucent wall 14.
This display comprises a kinetic portion indicated generally at 16a
and a static portion shown generally at 16b. In the illustrative
embodiment of my invention, the kinetic portion of the display
encompasses a circular area in the middle of wall 14 while the
static portion of the display fills the remaining area of the wall
14 surrounding that circular area.
As suggested in FIG. 1, the static display portion 16b consists of
angular areas of various sizes, shapes and colors, while the
kinetic portion 16a is comprised of rounded areas which constantly
change in size and shape as well as in color. The arrangement for
generating these static and changing color areas will be described
presently.
Turning now to FIGS. 2 and 3, housing 10 contains a multitude of
dividing walls 22 arranged generally perpendicular to the
translucent housing wall 14. Walls 22 are of varying length and
extend in various directions so as to divide the interior of
housing 10 into a multiplicity of odd-shaped compartments 24. As
best seen in FIG. 3, the wall 22 portions lying within a central
circular area 26 extend back from housing wall 14 a distance of
only about half the depth of housing 10. On the other hand, those
walls 22 portions lying outside area 26 extend the full depth of
the housing. In other words, the dividing walls within circular
areas 26 are recessed into the back of housing 10.
Still referring to FIGS. 2 and 3, a wheel shown generally at 28
fits within this recessed circular area 26. Wheel 28 comprises a
flat disc 32 whose diameter is slightly less than the diameter of
area 26 in housing 10. Several dividing walls 34 extend out
generally perpendicular to disc 32 for a distance slightly less
than the depth of the recessed area 26. Walls 34 are also of
varying lengths and extend in various directions so that they
define a number of compartments 36 on the face of the wheel. The
compartments 36 toward the center of the wheel are fully enclosed,
while those at the edge of the wheel are open-sided.
Preferably, but not essentially, walls 34 on wheel 28 have the same
arrangement as the walls 22 within recessed area 26 in housing 10.
Consequently when the wheel is in place as shown in FIG. 3 and
oriented at a particular angle relative to the housing, the
compartments 36 are all in register with the compartments 24 in the
housing. I have found that this arrangement produces an optimum
number of color and design variations.
Housing 10 has a rear wall 10a, shown in FIG. 3 and partially in
FIG. 2 covering the back of the housing outside area 26.
Consequently, the dividers 22 outside area 26 are normally not
visible from the rear of the display device.
Wheel 28 is connected at its axis to the shaft 38a of a small
electric motor 38. Motor 38 and the attached wheel 28 are supported
on the housing by means of straps 42 extending out in different
directions from the motor and attached to the housing rear wall 10a
by screws 44 or similar fasteners. When the motor and wheel are
properly mounted, the wheel can rotate about its axis within the
area 26 without its dividers 34 touching the dividers 22 in the
housing.
Still referring to FIGS. 2 and 3, a number of lamps 46 are
installed through openings (not shown) in the housing rear wall 10a
and in the wheel disc 32. Suitable clips (not shown) are used for
this so that the lights can easily be replaced. Lamps 46 project
into the compartments 24 and 36 and preferably there is at least
one lamp in each compartment. For best results, lamps 46 should be
colored differently and include heat-responsive circuit breakers so
that they blink on and off at different times in much the same
manner as some Christmas tree lights.
Turning to FIGS. 3 and 3A, lamps 46 on wheel 28 are all
electrically connected together in series or in parallel by
electrical leads 48 which lead to a pair of sliding contacts 52a
and 52b. These contacts make sliding contact with a pair of
concentric ring electrodes 54a and 54b, respectively, on the face
of an insulating disc 56 which is affixed to the front of the motor
38 housing. An opening 58 is provided at the center of the disc to
accommodate the motor shaft 38 and the ring electrodes 54a and 54b
are electrically connected to the power line which supplies the
motor 38. The lamps 46 in housing 10 are also connected by leads
48' (FIG. 3) to the power line.
When the unit is energized, the lamps 46 which are mounted in the
housing wall 10a illuminate the compartments 24 in which they are
located so as to produce the static color design 16b shown in FIG.
1. As mentioned previously, lamps 46 should be colored differently
and, most preferably, should blink on and off so that the design
portion 16b is not truly static in the strict mathematical
sense.
The kinetic portion 16a of the illuminated display is produced by
the blinking lamps 46 in the wheel compartments 36 which are
constantly changing position relative to their counterparts in the
compartments 24 within the area 26 of housing 10. The arrangement
is such as to create wavy areas having varying colors, hues and
intensities which can only be suggested in FIG. 1 and which are
continually changing. The illustrated pattern has distinct
divisions. However, in reality this is not the case because wall 14
is translucent or frosted.
The present device produces an extremely wide variety of color
designs in the kinetic portion 16a of the display. This is due in a
large measure to the shadow effect produced by the dividing walls
22 and 34. At any given moment, the light from one, two or even
three compartments on wheel 28 may be projected into a given
compartment in housing 10. Consequently, the area of the
translucent wall 14 corresponding to that housing compartment will
be a mixture of all those colors. However, the relationship between
these opposing compartments is constantly changing so that the
color contribution to the design from the various wheel
compartments is also continually changing. Thus, both the hue and
the intensity of the components making up the design portion in
question change correspondingly.
Furthermore, the angle at which the light from a lamp 46 on wheel
28 is projected into a compartment 24 in the housing varies as the
wheel turns. At one point, light from the lamp may be directed
straight into a housing compartment. At the next instant, the light
from the same lamp may reflect off one or another of the walls 22
defining that compartment and thence through the wall 14, thereby
causing a change in intensity of the portion of the kinetic design
contributed by that lamp. At the same time, light from another lamp
on the wheel may be projected into the same compartment in much the
same manner at varying angles so that the hue of that design
portion changes as well.
The movement of the lamps 46 relative to the housing divider walls
22 also creates constantly moving shadow effects which contribute
to the overall design playing upon the translucent wall 14. All of
these lighting effects contribute to making a very complex
illuminated multicolored pattern which continually changes in a
random fashion. Thus, as a practical matter, the observer never
sees the same design a second time.
If the arrangements of the dividing walls 22 within area 26 and the
dividing walls 34 are the same, then once during each revolution of
wheel 28, the compartments 24 and 36 will be in register. At that
instant, the kinetic portion 16a of the display will look very much
like the static portion 16b in FIG. 1. That is, it will be composed
of straight-sided areas having different colors, with some of these
areas blinking at that instant as well.
Even more complex display patterns are possible using the present
technique by employing two or more rotatable wheels which rotate
relative to one another and to housing 10. In other words, the unit
may include at least one intermediate wheel situated within area 26
between housing 10 and wheel 28. In this event, the intermediate
wheel does not include a disc 32, but is composed of divider walls
supported by a shaft extending to the geometric center of the array
of divider walls. That is, the intermediate wheel consists of
open-ended compartments through which the light from the lamps on
wheel 28 projects toward the translucent housing wall 14. The
intermediate wheel is geared to motor 38 so that if it runs at a
different speed than wheel 28, rotation of both wheels at once
produces very complex design patterns composed of different color
shades and shadows mixing and merging in a completely random
way.
Other variations on my principle also suggest themselves. For
example, some or all of the dividing walls 22 and 24 may be curved
instead of straight. Also, their heights may vary so as to provide
some light leakage from one compartment to another. Also, of
course, the speed of motor 38 can be made to vary to contribute
another kinetic component to the display portion 16a . Still
further design variations are possible by including a perpendicular
wall 39 around part or all of the circumference of disc 32 as shown
in dotted lines in FIG. 2.
While my display creates very complex kinetic designs, it is
constructed of relatively simple and inexpensive parts. Therefore,
its cost is relatively low so that store owners are well able to
afford to purchase the unit. Furthermore, the display has only one
moving part and, therefore, can be expected to have a long, useful
life even though it may be operated for long periods without
interruption. Still, however, when repairs are necessary, such as
when a lamp burns out, the parts are relatively accessible so that
maintenance costs are kept to a minimum.
It will thus be seen that the objects set forth above, among those
made apparent from the preceding description, are efficiently
attained and, since certain changes may be made in the above
construction without departing from the scope of the invention, it
is intended that all matter contained in the above description or
shown in the accompanying drawing shall be interpreted as
illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended
to cover all of the generic and specific features of the invention
herein described.
