BALANCING SKILL GAME
Abstract
An elongated substantially cylindrical toy simulating the head
end portion of a snake including a throat portion, flanges, and
head having a base member opposite the head is adapted to be
balanced in an upright position in the palm of a player's hand. An
electrical circuit, including lamps selectively located in the toy
and a time delay circuit for each lamp, a source of electrical
energy and manually operated switches adjacent the base, is
contained by the toy which selectively energizes the lamps in a
predetermined sequence while the toy remains balanced. A plurality
of mercury switches are located in the body and are connected in
series between the source of electrical energy and lamps. If the
toy is caused to tilt beyond a certain point the mercury switches
open and deactivate the time delay circuits and lamps.

Description
BACKGROUND OF THE INVENTION
1. Field of the invention
The present invention relates to games of skill and more
particularly to a toy comprising an elongated hollow member
simulating a snake, such as a Cobra, or the like, which contains an
electrical circuit for illuminating portions of the toy during a
balancing act.
2. Description of the prior art
I do not know of any patents disclosing a game or toy which is
illuminated in a sequence determined by time lapse while the toy is
balanced by a user.
SUMMARY OF THE INVENTION
An elongated substantially cylindrical hollow toy, having a base
end, simulates, at its other end, the configuration of a snake,
such as a Cobra, having a neck portion, laterally projecting flange
portions and a head including eyes. The toy is preferably formed of
translucent plastic material. The hollow interior of the toy
contains an electrical circuit including a source of electrical
energy disposed adjacent the base end, a lamp located in the throat
area and a pair of lamps respectively located in the flanges, a
head illuminating lamp and a pair of lamps illuminating the eyes.
Time delay means in the circuit successively illuminate the lamps
and de-energize them in sequence during such time as the toy
remains balanced in an upright position while supported by the
user's hand in response to a starting switch adjacent the base end
of the toy. In the event balance of the toy is lost by a player
during a game, one or more of a plurality of gravity actuated
mercury switches opens the circuit and interrupts the lamp
illuminating sequence.
The principal object of this invention is to provide a game toy for
improving the balancing skill of users wherein portions of the toy
is illuminated in sequence by a plurality of lamps during a
predetermined period of time during which balance of the toy must
be maintained.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Like characters of reference designate like parts in those figures
of the drawings in which they occur.
In the drawings:
The reference numeral 10 indicates the toy, as a whole, which is
preferably formed of translucent plastic material elongated
cylindrical in general configuration having exterior roll threads
12 adjacent its base end 14 and having its other end portion
simulating a snake, such as a Cobra, having opposing longitudinally
extending laterally projecting flanges 16 defining a throat portion
18 and terminating in a snake head shape 20 including a pair of
eyes 22. The toy is provided with a hollow interior, indicated at
24, which extends upwardly from its base end 14 to at least the
position of the eyes 22. The base end 14 is normally closed by a
base member or cap 26 threadedly engaging the threads 12. This
hollow interior 24 contains an electrical circuit, indicated
generally at 28. The circuit 28 principally consists of four
interconnected identical time delay configurations or sections,
respectively contained by the shield lines W, X, Y and Z, employed
to illuminate a plurality of different colored lamps L1, L2, L3 and
L4 in a predetermined sequence for an interval of predetermined
time, for example, thirty seconds each for the lamp L, the pair of
lamps L2, the lamp L3 and a shorter interval of time, for example,
fifteen seconds for the pair of lamps L4. The lamp L1 is preferably
located in the throat area 18 while the pair of lamps L2 is located
in the respective flange 16. The lamp L3 is located in the head
portion 20 and the pair of lamps L4 is located adjacent the
respective eye 22.
A battery B or a pair of batteries, such as flashlight batteries,
are disposed in series within the base end portion of the toy and
maintained in electrical contact with each other and the circuit by
a spring 29. The negative side of the battery B is connected to
ground through an "off-on" switch S1. The positive side of the
battery B is connected in series through four miniature mercury
bulbs acting as normally closed switches S2, S3, S4 and S5. These
mercury switches are arranged in a four-quadrant cluster with the
contacts disposed toward the center of the cluster and arranged
with a slight tilt with the degree of tilt determined by the
accuracy of balance to be maintained by the player using the toy.
The purpose of these mercury switches is to interrupt the lamp
lighting sequence in the event balance of the toy is lost by the
player during a predetermined period of time. A positive current
source wire 30, connected with the mercury switch S5, is connected
with one terminal of a normally open push-button starter switch S6.
The other terminal of the starting switch S6 is connected to the
control gate 32 of a silicon controlled rectifier Q1 through a
resistor R1. The cathode 34 of Q1 is connected to ground. The anode
36 of Q1 is connected to the source wire 30 through a resistor
R2.
Each time delay section W, X, Y and Z basically includes a silicon
controlled rectifier, a PNP transistor, a unijunction transistor,
resistors, capacitors, at least one lamp and a potentiometer. In
the interest of brevity only the time delay section W will be
described in detail.
The anode of Q1 is also connected to the base 38 of a PNP
transistor Q2 through a resistor R3. The emitter 40 of Q2 is
connected to the source wire 30. The collector 42 of Q2 is
connected to ground in series through a potentiometer P1, a
resistor R4 and timing capacitor C1. The joined contacts of
resistor R1 and capacitor C1 are connected to the emitter 44 of a
unijunction transistor Q3. Base-two 46 of Q3 is connected to the
source wire 30 through a resistor R5. Base-one 48 of Q3 is
connected to ground through a resistor R6.
Base-one 48 of Q3 is also connected to the control gate 50 of a
second silicon controlled rectifier Q4. The anode 52 of Q4 is
connected to the source wire 30 in series through the lamp L1. The
cathode 54 of Q4 is connected to ground. A capacitor C2 is
connected in series between the anodes 34 and 52 of transistors Q1
and Q4.
This substantially completes the description of the time delay
section W. The capacitor C2 triggers the time delay sequence of the
next time delay section X as presently described.
The time delay section X, illuminating the pair of lamps L2,
includes a PNP transistor Q5, unijunction transistor Q6, silicon
controlled rectifier Q7, potentiometer P2, resistors R7, R8, R9 and
R10 and capacitors C3 and C4, similarly connected with each other
and the source wire 30 wherein current through the resistor R7,
connecting the anode 52 of transistor Q4 to the base of transistor
Q5, initiates the lamp lighting sequence of the lamps L2 as
presently explained.
The PNP transistor Q8, unijunction transistor Q9 and silicon
controlled rectifier Q10, interconnected by potentiometer P3,
resistors R11, R12, R13 and R14 and capacitors C5 and C6 forming
the time delay section Y and connected in the manner previously
described, illuminates the lamp L3 in sequence as presently
explained.
Similarly PNP transistor Q11, unijunction transistor Q12 and
silicon controlled rectifier Q13, connected with the potentiometer
P4 and resistors R15, R16, R17, R18 and capacitors C7 and C8
forming the time delay section Z in a like manner illuminate the
lamps L4.
OPERATION
In operation the "off-on" switch S1 is closed and the toy 10 is
positioned with the cap 26 supported by the upwardly disposed palm
surface of a player, not shown. The push-button switch S6 is
momentarily closed to start the time delay sequence. When the
switch S6 is closed, positive potential is applied from the battery
B through the balance switches S2, S3, S4 and S5 through the
resistor R1 to the control gate 32 of transistor Q1. Transistor Q1
conducts and applies a negative potential to the base 38 of
transistor Q2 through resistor R3. Transistor Q2 is normally
nonconductive by the positive potential applied to its base through
resistors R2 and R3. The negative potential applied to the base 38
of the transistor Q2 results in charging the timing capacitor C1 by
the rate of current through the potentiometer P1 and resistor R4.
When the capacitor C1 is fully charged its positive potential is
applied to the emitter 44 of unijunction transistor Q3 so that Q3
becomes conductive resulting in a positive potential at its
base-one connection 48 with the resistor R6 which is also applied
to the emitter 50 of the silicon controlled rectifier Q4 which then
conducts and illuminates the lamp L1. Current through the lamp L1
also results in the potential at one side of capacitor C2 to go
negative applying a commutating potential to the anode 36 of
transistor Q1 thus interrupting current through transistor Q1.
Current through the transistor Q4 is also applied to the base of
transistor Q5 through resistor R7 thus initiating the time delay
action in the second section X of the circuit 28. Current sequence
through the transistor Q5, potentiometer P2, unijunction transistor
Q6 and silicon controlled rectifier Q7 and their connected
resistors and capacitors is identical to that described for the
time delay action of section W and illuminates the pair of lamps L2
for the predetermined duration of time. Similarly conduction of the
silicon controlled rectifier Q7 turns off the silicon controlled
rectifier Q4 by the negative potential applied to its anode by the
capacitor C4. Similarly potential applied to the control gate of
silicon controlled rectifier Q10 causes it to conduct and
illuminate the lamp L3 and turn off the silicon controlled
rectifier Q7, by the capacitor C6 and after the predetermined time
delay current is applied to the control gate of silicon controlled
rectifier Q13 for illuminating the pair of lamps L4 and similarly
turn off silicon controlled rectifier Q10 by the charge on
capacitor C8.
As stated hereinabove, the time span or delay of the fourth or last
section Z is of shorter duration in accordance with the smaller
value timing capacitor C7. The sequence of illuminating the lamps
L1 through L4, as above described, progresses as long as the toy 10
is balanced in a substantially vertical position by the player. In
the event the player loses or almost loses balance of the toy 10
current from the battery B to the current source wire 30 will be
interrupted by the opening of one or more of the mercury switches
S2, S3, S4 or S5 in accordance with the degree of inclination of
the longitudinal axis of the toy with respect to the vertical thus
interrupting the time delay sequence and disqualifying the player
attempting to balance the toy 10 for the predetermined span of
time. Diametrically opposed prongs or pins 60, secured to the base
end portion of the toy, serve as handles which may be grasped by
the player when balance is lost to avoid damage to the toy
components as by dropping the toy. The lamp lighting sequence may
then be restarted by a subsequent closing of the starting switch
S6.
Obviously the invention is susceptible to changes or alterations
without defeating its practicability, therefore, I do not wish to
be confined to the preferred embodiment shown in the drawings and
described herein.
