Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to sporting goods
and toy products, and more particularly to a ball such as a
football, round ball, or any other game ball or play ball which is
internally lighted.
BACKGROUND OF THE INVENTION
[0002] A wide variety of games are played both in the field and on
the court where a ball is kicked, thrown, bounced, paddled, and
batted as part of game play. Such game balls must have a relatively
heavy-duty construction in order to survive the shock forces
resulting from the ball repeatedly rebounding off hard surfaces.
Such balls and toys stimulating ball play have always been very
popular. Many of the consumers of balls and toy products simulating
balls have expressed a desire to use said products in a darkened
environment as indicated by relatively large sales of such prior
art products. However, relatively expensive, heavy-duty, electrical
components must be used to survive the shock forces resulting from
a ball repeatedly rebounding off hard surfaces.
[0003] Several designs have been proposed for illuminating game
balls to enable play in dark conditions.
[0004] U.S. Pat. No. 6,117,030 describes an illuminated translucent
ball having an access opening in its side and in the opening is
mounted a case that contains batteries in a battery compartment, a
mount for a light source in the form of an light emitting diode
(LED), and a switch for selectively activating the light source.
The switch is formed in a cap that is used for closing the access
opening so is actuable from the surface of the ball.
[0005] U.S. Pat. No. 5,228,686 describes an illuminated translucent
ball that has LEDs mounted in the inner surface of the ball shell
and are connected to an interior rechargeable battery set via a
power switch for energizing the LEDs. The switch is mounted in the
interior of the ball and is actuated by a slender rod-like tool
that must be inserted into a switch access passage. The batteries
are recharged via a recharging connector mounted interior to the
ball and accessed via a passage that extends from the recharging
connector to the surface of the ball body, and a slender rod-like
electrical connector is inserted through the access passage to
engage the recharging connector for recharging the batteries.
[0006] U.S. Pat. No. 4,776,589 describes an illuminated translucent
ball having an opening in its side that accesses a compartment in
which are mounted a battery and lights. A switch is mounted in the
wall of the ball to connect the battery to the lights and
illuminate the ball. A cap with living hinge is used to create a
watertight seal for the opening. The cap is opened to access the
compartment and install or replace batteries.
[0007] U.S. Patent No. 4,133,528 describes an illuminated
translucent ball that has a passage there through into which an
insulating, rigid case is inserted. The ends of the case may be
substantially flush with the surface if the ball. The case has
mounted therein lights and a battery, and the ends of the case are
sealed by end caps that are also used to access the interior of the
case to replace the batteries. One end cap may serve as a switch to
turn the lights on and off.
[0008] These and other similar designs utilize components,
materials and construction that, while generally suitable for their
purposes, make the illuminate balls relatively complex and
expensive to manufacture and thereby render them undesirable for
applications where such design and high manufacturing cost is not
needed. Hence, there is a need for an illuminated game ball
designed for relatively simple, inexpensive manufacture, assembly,
and use.
SUMMARY OF THE INVENTION
[0009] The shortcomings of the prior are overcome by the present
invention. An illuminated ball is provided that is rugged enough
for use, but which is relatively simple and inexpensive to
manufacture, and is easy to use.
[0010] There is a hollow compartment of a soft membrane PVC layer
at the central part of a translucent ball in which one or more for
light emitting diodes (LEDs) and a capacitor or rechargeable
battery are mounted, so that the ball may be lighted to be played
with for fun even at night or in dark places such as a beach,
swimming pool or lawn in order to improve its practicability and
novelty.
[0011] The interior capacitor or rechargeable battery is connected
via wires to a charging connector mounted flush with the outer
surface of the ball. When the ball is to be lighted for play a
power supply with a mating charging connector is utilized to charge
the capacitor or batteries by inserting the mating connector into
the flush mounted connector. The charged capacitor or batteries
illuminate the LEDs for play.
[0012] The use of a charging connector and a sealed, hollow
compartment internal to the ball creates a game ball that is
impervious to water and can be used for play in the water.
DESCRIPTION OF THE DRAWING
[0013] The invention will be better understood upon reading the
following Detailed Description in conjunction with the drawing in
which:
[0014] FIG. 1 shows the illuminated ball in accordance with the
present invention; and
[0015] FIG. 2 is a schematic diagram of the illuminated ball.
DETAILED DESCRIPTION
[0016] In FIG. 1 is a preferred embodiment of the invention showing
details of an illuminated, inflatable game ball. There is shown a
game ball 10 having a translucent wall 20 defining a hollow
interior 21. The translucent material may be made of different
colors while still being translucent. Mounted in wall 20 is a valve
11 that is well known in the art and is used to inflate ball 10. At
opposite sides of ball 10 are manufactured openings 22 and 23 that
are used in assembling illumination means into ball 10.
[0017] Stretched between and fastened to openings 22 and 23 by
thermally fusing or a flexible adhesive (not shown) is a hollow
piece of flexible PVC tubing 12. After being fastened to the
openings 22 and 23 the interior of tubing 12 is accessible from the
exterior of ball 10.
[0018] Separately assembled is a module 13 with a charging
connector 17 attached thereto by wires (not shown). Module 13
contains a light emitting diode (LED) 14, a resistor (not shown in
FIG. 1, but shown in FIG. 2), and a capacitor 15 that is charged
and acts as a power source for LED 14. Alternatively, a
rechargeable battery may be used in lieu of capacitor 15. There is
a series circuit created through LED 14, the resistor, capacitor 15
and charging connector 17 when a mating charging plug 19 of a power
source/battery charger 18 is not plugged into connector 17. Thus, a
charged capacitor 15 will slowly discharge through LED 14, lighting
it and thereby illuminating ball 10. Charger 18 is preferably of a
type well known in the art and available in stores. Charger 18 can
be powered by replaceable batteries, or it can preferably have a
small power supply (not shown) that plugs into a standard 110 volt
household outlet to produce a d.c. voltage necessary to charge
capacitor 15. When charging plug 19 is plugged into charging
connector 17 it opens the series circuit there through created by a
normally closed contact (not shown in FIG. 1) and applies the d.c.
voltage to capacitor 15 to charge it. A schematic of the circuit
for ball 10 is shown in FIG. 2 and is described further in this
detailed description.
[0019] After ends of tubing 12 are fastened to openings 22 and 23,
module 13 is inserted into PVC tubing 12 using a long slender rod
like tool (not shown) to push module 13 into tuning 12, expanding
the tubing as seen in FIG. 1, until module 13 is in the center of
ball 10 as shown. With module 13 located in the center of ball 10
the wires are long enough that connector 17 is still outside ball
10. The wires, not shown in FIG. 1 but shown and described with
reference to FIG. 2, connecting module 13 to connector 17 are
positioned alongside the tool at the time of installation and the
diameter of the tool is small enough not to interfere with or
damage the wires or connector 17 during installation of module
13.
[0020] After module 13 is inserted into tubing 12 to the center of
ball 10, connector 17 is then inserted into opening 22 with some
adhesive (not shown) to permanently attached it to ball 10 such
that the entrance to charging connector 17 is flush with the
surface of ball 10. A small amount of adhesive 23 may also be
inserted through opening 23 to be in contact with module 13, as
shown, to assure that it stays positioned in the center of ball 10.
The use of charging connector 17 sealed into opening 22 and
creating a sealed, hollow compartment internal to ball 10 using
tubing 12 and sealant 23 creates a game ball that is impervious to
water and can be used for play in the water.
[0021] An on-off switch may be implemented, without changing the
design of ball 10 described above, so batteries 15 may be charged
and ball 10 be put away, or to preserve any remaining charge in
batteries 15 following a use of ball 10. Such a switch is
implemented by using a dummy plug (not shown) that is identical to
the dimensions of plug 19, but has no charger associated therewith.
When this dummy plug, which may be a real plug or a dummy one made
from plastic, is inserted into charging connector 17 the series
circuit described above is opened and batteries 15 cease
discharging through LED 14. When it is desired to use ball 10 the
dummy plug is removed from connector 17 closing the series circuit
described above and batteries 15 commence slowly discharging
through LED 14. Thus operation is better understood with reference
to FIG. 2 and the following description thereof
[0022] FIG. 2 shows an electrical schematic diagram of illuminated
ball 10. Module 13 is shown with capacitor 15, resistor 26 and LED
14. The wires 24 and 25 that connect charging connector 17 to
module 13 are also shown. Finally, the details of charging
connector 17 are shown.
[0023] As shown in FIG. 2 there is no charging plug 19 inserted
into connector 17. Accordingly, there is a circuit starting at the
uppermost terminal of capacitor 15, as shown in FIG. 2, and through
wire 24 to flexible contact 17a in connector 17. As shown, a
contact 17b is in electrical contact with contact 17a so the
electrical circuit is extended therethrough and via wire 25 to the
positive terminal of LED 14 in module 13. The circuit includes LED
14 and current limiting resistor 26 and is completed at the
lowermost terminal of capacitor 15 as shown in FIG. 2. With this
complete circuit current flows and LED 14 functions to emit light.
When capacitor 15 is discharged the LED ceases to emit light.
[0024] When a dummy plug 19 is inserted into connector 17 it causes
flexible contact 1 7a to be moved away from contact 17b thereby
opening the circuit. No electric current flows and LED 14 does not
emit light. The use of plug 19 permits capacitor 15 to be charged
ahead of time and to retain its charge until ball 10 is to be
used.
[0025] When plug 19 of battery charger 18 is inserted into
connector 17 it pushes against flexible contact 17a moving it away
from contact 17b opening the circuit. In this instance a portion of
plug 19 called the tip has a negative potential thereon from
battery charger 18 and this negative potential is connected via
contact 17a and wire 24 to one terminal of capacitor 15. At the
same time a portion of plug 19 called the sleeve and having a
positive potential thereon from capacitor charger 18 is in
electrical contact with terminal 17c. Current flows through the
circuit in the reverse direction, through now forward biased LED 14
and resistor 26, and capacitor 15 is charged. Preferably capacitor
15 is a polarized capacitor, such as an electrolytic capacitor,
having a positive and negative terminal, and it's positive terminal
is connected to resistor 26 while its negative terminal is
connected to contact 17a via wire 24.
[0026] While what has been described hereinabove is the preferred
embodiment of the invention, one skilled in the art will appreciate
that numerous changes may be made without departing from the spirit
and scope of the invention. For example, two or more LEDs may be
utilized, and/or additional LEDs may be strung out from module 13
to stretch from the center of the ball toward the surface of the
ball. Alternatively, the module, charging plug and any additional
LEDs (if any) may be pre-assembled inside the tubing before the
whole assembly is inserted through an opening and guided into
proper position using alignment rods.
