Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to display fountains, and more particularly
to a water fountain adapted to be readily connected to existing
water-pressure and filter systems found in swimming pools.
2. Description of the Prior Art
As is well known in the art, various problems and difficulties have
been encountered in providing a novel, maintenance-free,
water-display fountain that is suitably adapted to the various
existing water-pressure and filter systems of swimming pools,
reflecting ponds, and like bodies of water, wherein decorative and
aesthetic features can be easily added. For the average individual
who owns a swimming pool or a large pond, it is difficult to obtain
a water-display apparatus to enhance his pool or pond which can be
easily incorporated into the existing water-supply system. This is
the case with respect to swimming pools wherein the water-filtering
system is a large unit set apart from the pool area, requiring
complex plumbing connections and, in addition, a complex electrical
system which in a body of water could create a safety hazard. Thus,
a very limited number of water displays can be found for use in
such bodies of water wherein they are to be used in conjunction
with swimming or similar aquatic activities. Conventional hardware
and plumbing items do not permit a simple initial installation, nor
do they provide for ease of repair and maintenance.
Hence, to the applicants' knowledge, there is at the present time
no suitable, versatile, water-display unit that can be adapted to
operate in existing pools and ponds; and will, in addition, provide
an aesthetic water-display unit that can operate in conjunction
with varied pool water-filtering systems and can be easily
istalled, eliminating the necessity for unsightly, complex
plumbing.
SUMMARY OF THE INVENTION
The present invention discloses an illuminating, aquaticdisplay
fountain adapted to be installed within existing swimming pools,
fish ponds, and like bodies of water, wherein an aesthetic water
display is provided with a minimal amount of problems. The display
fountain comprises a floatable support structure forming a
channeled frame having a plurality of outwardly-extending,
radiating arms, each of which is adapted to receive light fixtures,
such as light bulbs, capable of being submerged in water during
their operation. There is a central tubular housing fixedly secured
within a central hole of the support structure and positioned
vertically, to rotatably receive a color wheel cover, said wheel
being formed as a circular frame having spaced openings in which
are disposed various colored panes of transluscent material. In
addition, there is provided a means by which the wheel is rotated
about the central housing, causing the various color panes to pass
over the light emanating from the bulbs. During the rotation of the
wheel, water is supplied by a water-pressure system to pass through
the central housing by means of conduits from the water-supply
system connected to the lower inlet of said housing into a
sprinkler-head nozzle. At this time, the water spray is illuminated
by the various colors emanating from the light fixtures.
Since most swimming pools are provided with built-in, water-filter
systems in which the filtered water is returned under pressure,
there is already provided the required pressure and water flow to
operate the apparatus effectively. Thus, the conduits of the
apparatus can be connected to the existing system by various means,
such as coupling the conduit line to the outlet opening of the
filter system which is normally found in the side wall of the pool.
However, it can be readily understood that this display unit can be
designed to be incorporated as an itegral part of the filter system
of any pool during construction. Or, it can be incorporated within
any type of body of water by adding its own pressure-supply
system.
OBJECTS AND ADVANTAGES OF THE INVENTION
The present invention has for an important object a provision
whereby an aesthetic water fountain can be incorporated within
existing swimming pools or the like bodies of water.
It is another object of the invention to provide an illuminated,
aquatic-display fountain that can be operated during the day or
night, with or without the use of its light fixtures, and still
provide a pleasing, effective display.
It is still another object of the invention to provide an
illuminated aquatic fountain that is equally capable of being
connected with an existing water-pressure system, such as a filter
system of a swimming pool, or being adapted with its own integral
pump system.
It is a further object of the present invention to provide an
apparatus of this character that is easy to install, service and
maintain.
It is still a further object of the invention to provide an
apparatus of this character that is relatively inexpensive to
manufacture.
Still another object of the present invention is to provide an
apparatus of this character that is simple and rugged in
construction.
It is still another object of the invention to provide an apparatus
of this character wherein the electrical system operates on a high
voltage input and a low voltage output, such as 12 volts or 28
volts, and wherein the wire thereof can be disposed within the
water conduit leading from the pool to the apparatus.
Other characteristics, advantages and objects of this invention can
be more readily appreciated from the following description and
appended claims. When taken in conjunction with the accompanying
drawings, this description forms a part of the specification
wherein like references and characters designate corresponding
parts in several views.
DESCRIPTION OF THE DRAWINGS
Referring more particularly to the accompanying drawings, which are
for illustrative purposes only:
FIG. 1 is an exploded perspective view of the preferred embodiment
showing a portion of a swimming pool;
FIG. 2 is an enlarged cross-sectional view of one portion of the
apparatus to illustrate its operational mode;
FIG. 3 is an enlarged perspective view of the rotating means
wherein a portion thereof is broken away;
FIG. 4 is a perspective view of an alternative embodiment;
FIG. 5 is an enlarged cross-sectional view of the electrical,
rotating, contact means adapted for use with the alternative
embodiment; and
FIG. 6 shows an alternative arrangement of connecting the water
conduit to an existing pool water-filter system.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings and particularly to FIG. 1, there is
shown a portion of a swimming pool, indicated generally at 10,
represented by a small fragment of a pool coping 12 and a body of
water 14. The pool is understood to be adapted with a recirculating
water-filter system, which is not shown, but is suitably connected
with the pool water 14 through return pipe system 16 provided with
a typical outlet receptacle 18 located below the water line and
generally found on the side wall of said pool 10. Generally,
recirculating water-filter systems in swimming pools include a
conventional motor, pump, filter and interconnecting plumbing
whereby water from said pool is drawn therefrom, circulated through
said system, and finally returned back into said pool at a
controlled rate of flow and pressure. Thus, such a system could
ideally incorporate a display fountain unit, generally indicated at
20, with the required operating means to effect an aesthetic water
display, either by night or day.
The water fountain 20, as seen in FIGS. 1 and 2, comprises a
floatable support structure, indicated generally at 22, formed as a
channeled frame 24 having a plurality of radially extending arms 26
which are centrally interconnected, at which point a central
opening 28 is therein disposed. Each outer free end of each arm is
provided with support brackets formed as annular rings 30, said
rings having a cross section of an upside-down, U-shaped channel in
which a floatable means is inserted therein, thereby providing the
support-frame structure 22 with the necessary buoyancy to float
said structure at water level. The floatable means can be of any
suitable material capable of floating in a body of water without
damage, such as cork, fiberglass, etc., but preferably a
polyurethane closed-cell foam. Thus, the floatable material, as
indicated at 32, has an annular configuration adapted to be fixedly
received in the channel of rings 30.
As previously mentioned above, there is provided a central opening
28 in said support structure 22 in which there is fixedly received
therein a central tubular housing 34 having an enlarged body
portion 35 arranged intermediate the threaded ends 36 and 38,
respectively. In addition, the enlarged body 35 is provided with an
annular flange 37 at its lower portion (as seen in FIG. 2) adjacent
the lower, reduced-diameter member 40 of said housing 34, said
member 40 being provided with an outer diameter substantially equal
to the inner diameter of opening 28 whereby said member 40 is
received therein and is secured in fixed relationship to said
support structure 22 by means of a washer 41 and a nut 42 threaded
to end 36.
Each of said annular rings 30 is adapted to removably support a
light fixture, generally indicated at 44, wherein said light
fixture comprises a light bulb 46 of the sealed-beam type which is
compatible for use in or out of water and operates within a
low-voltage system of between 6 volts and 28 volts. Said light is
interdisposed between a retainer clip 48 and a retainer-support
shield 50, as can be seen in FIG. 2, and is held in a central
position relative to the annular opening 52 of ring 30. The clip is
formed preferably of spring metal having a plurality of upstanding,
flexible fingers 54 integrally attached to an annular band 56
adapted to receive the lens portion of the light bulb 46. Said
fingers are formed to include a tongue member 58 at its upper free
end, which hooks over the top area of ring 30 when said fingers are
inserted within opening 52. The lower part of the fingers are then
formed with an annular clasp portion 59 which projects outwardly
just below the lower, inner edge of ring 30 and provides a holding
means for the annular shield 50, whereby said shield is held
against the lower edge of ring 30 by means of the inwardly bent
annular lip 60. The shield also includes an annular flange 62 that
projects inwardly, thereby providing the means by which light bulb
46 is held against the band 56. To allow for water circulation
about the light 46, a plurality of holes are disposed circumjacent
within flange 62.
Thus, it can be readily understood that when the bulbs are so
positioned light will shine upwardly through opening 52 in ring 30
and pass through a rotatable color wheel, generally indicated at
64. This color wheel covers each bulb because the radius thereof is
at least equal to the length of each arm 26. Color wheel 64
comprises a circular frame formed from either metal or plastic, and
has a plurality of radially-juxtaposed, transluscent panes 66
disposed in corresponding radial apertures 68, said apertures being
formed in the flat surface plate 69. Hence, it is contemplated that
panes 66 will be made from various colored sheets of plastic.
There is a central hole 70 disposed within the surface plate 69
whereby said wheel 64 fits over the upper, reduced-diameter member
72 of said tubular housing 34.
To provide a means by which the wheel is rotated, there is
interposed between the wheel 64 and the enlarged body portion 35 of
the housing 34 a drive ring 74 fixedly secured to the underside of
plate 69. Said drive ring has an outer depending flange 75 and an
inner depending flange 76 which defines an opening axially aligned
with hole 70 for rotation about central housing 34. Said wheel
cover 64 is thus held in operable placement by means of a washer 77
disposed over hole 70 and locked into position by a keeper, such as
a snap ring or a rubber grommet 78. (See FIG. 2.)
There are various operating means that can be employed to rotate
the wheel 64, one being an electric motor and another being a water
operated drive means, indicated generally at 80. Accordingly, the
water operated drive means is formed in such a manner as to have a
housing 82 provided with a bore 84 vertically disposed therein,
whereby said housing is received on said enlarged body portion 35
of said central housing 34 and supported by said annular flange 37.
As the housing 82 is positioned thereon, a passage 86 horizontally
disposed therein is aligned with a second passage 88 disposed in
said body portion 35, as seen in FIG. 2. Therefore, communication
between bore 90 of the central tubular housing 34 and chamber 92 of
the motor housing 82 is established. Thus, water flows from the
pool's water-pressure supply system through conduits 94 and enters
the central housing 34 under pressure, passing into and out of a
sprinkler nozzle head 96 which is threaded to end 38 of said
housing 34. As the water flow passes through bore 90, water
therefrom is allowed to enter passages 88 and 86, respectively,
entering chamber 92 in which there is operably mounted a vane-pump
means 98. The incoming pressurized water rotates the vanes as it
passes through chamber 92 and out of outlet 99. At this time, a
worm gear 100 attached to said rotatable vanes 98 causes gear 101
to move, thereby imparting a rotational torque movement to drive
disc 102 through shaft 103. In FIG. 2 it is thus shown that drive
disc 102 engages the outer depending flange 75, thereby propelling
the color wheel about said central housing 34. When light bulbs 46
are lit, the light beams therefrom are projected through the
various colored window panes as they pass over each bulb during
rotation. Hence, the light beams are reflected upon the droplets of
water emitted from the sprinkler head 96.
Referring now to the conduit 94, there is provided a plurality of
pipes that are interconnected end-to-end wherein one end thereof is
arranged with a connecting coupling means which is adapted to be
coupled to the outlet 18 of said water-supply system of the pool,
as seen in FIG. 1. This coupling means may vary from pool to pool,
but is shown herein as a plug adapter 103 which is fitted to outlet
18 in a somewhat permanent manner, and wherein pipe 104 of the
conduit 94 is shown as having means, such as a pair of extending
pins 105, to engage plug 103 which is provided with slots, not
shown. As mentioned, other suitable coupling arrangements can be
incorporated in place thereof. The opposite end of the conduit
includes and upright pipe 106 having threaded means whereby it is
directly secured to said end 36 of said central housing 34.
However, valves will most likely be required to adjust water flow
when more or less pressure is required in the system. Therefore,
valves 108 are shown disposed within the conduit 94.
In addition, there is also included a wiring system 110 that is
connected at one end to the light bulbs and the opposite end
thereof is attached to a low-voltage transformer 112. The provide
for ease of installation and safety, the wires are inserted and
passed through the water-flow conduits at any suitable point and
are shown entering through coupling tube 114 before ending in
outlet 18. Since the voltage in the wiring originates from
low-voltage transformer 112, there is no danger from the electrical
system.
Alternative Embodiment
Reference is made now to FIGS. 4 and 5 in which there is shown an
alternative arrangement for a plurality of water-display fountains
wherein each is provided with its own color-illuminating device
operably mounted thereon. Even though the apparatus is illustrated
with only two display units 200 and 202, respectively, it should be
understood that more units can be added, depending on the body of
water in which the apparatus is to be used.
Each unit 200 and 202 operates identically to display fountain 20
and is constructed in the same manner. However, as each color wheel
204 and 206 rotates about its own axis, both are interconnected to
a central, rotatable, carriage means, generally indicated at 208,
thereby providing a secondary simultaneous rotation for both
displays 200 and 202 about the rotational axis of said carriage
208. The lower portion of carriage 208 is connected to the
water-filter system in the same manner as described hereinabove for
the preferred form. That is, by use of said conduit system 94,
booms 210 and 212 extend oppositely from carriage 208, forming a
somewhat T-shaped configuration and having their outer ends adapted
with L members 214 in which upright members 215 are supported.
Thus, as water flows into carriage 208 through passages 216 and 217
(See FIG. 5.), then through booms 210 and 212, said water is
discharged from jets 218. Said jets 218 are positioned adjacent the
outer ends of the booms, wherein the jet 218 is disposed in boom
212 opposite the jet in boom 210 (not seen). It, therefore, can be
understood that the force from said jets will impart a rotating
movement to both displays as the water is sprayed under
pressure.
In order to provide electrical continuity, said carriage 208
includes a pair of electrical contacts 220, said contacts being
affixed to the stationary lower member 222 of said carriage (See
FIG. 5.), and engage circular contact bands 224 secured to the
upper rotatable member 228 of said carriage. Said contacts 220 and
224 are mounted oppositely to each other on extended horizontal
flanges 230 and 232, respectively, said flanges being held in
parallel relationship to each other by an annular guide rail 234.
Thus, a continuous electrical contact is maintained at all times
during the rotation of the boom members together with the display
units mounted thereto.
Referring to FIG. 6, there is shown an alternative arrangement for
connecting the water-display units to a water-pressure system where
it is not feasible to couple the conduit 94 within the body of
water. Thus, if a pool or other body of water does not have a
direct outlet, the conduit is then provided with additional
elements, such as pipe 240 which extends upward to a point just
above the pool's edge and is at the point demountably coupled to a
water-pressure system 16 by means of fittings, generally indicated
at 242. These fittings would include a flexible housing 244 that is
adapted to follow various configurations, depending on the
conditions between the pool's edge and the pressure system. It is
also contemplated that a two-way valve 246 will be disposed within
the pressure-return system, thereby permitting the flow of water to
be diverted to the display fountain when so desired.
The invention and its attendant advantages will be understood from
the foregoing description and it will be apparent that various
changes may be made in the form, construction and arrangement of
parts of the invention without departing from the spirit and scope
thereof or sacrificing its material advantages, the arrangement
hereinbefore described being merely by way of example, and we do
not wish to be restricted to the specific forms shown or uses
mentioned, except as defined in the accompanying claims.
