Description
RELATED APPLICATIONS
[0001] This application is a Continuation-In-Part of U.S. patent
application Ser. No. 09/383,914, entitled Whirling Amusement Device
And Associated Method Of Operation, filed Aug. 26, 1999.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to amusement devices that
contains an object that spins or whirls. More particularly, the
present invention relates to amusement devices that contain an
object that spins, a motor for spinning that object and a flexible
shaft disposed between the object and the motor.
[0004] 2. Description of the Prior Art
[0005] The prior art of toys and amusement devices is replete with
many examples of objects that spin and whirl. Many such devices are
powered by rotational momentum, such as tops and gyroscopes. Other
devices are powered by springs, such as windup ballerina figures.
Still many other devices utilize battery powered motors to create a
spinning motion.
[0006] One variation of a battery powered amusement device is when
the object being spun is connected to the battery powered motor by
a flexible shaft. In such devices, the forces of inertia and
centrifugal force cause the flexible shaft to oscillate at the
shaft spins. The oscillation of the shaft causes the object being
spun to move in an erratic manner. Such prior art devices are
exemplified by U.S. Pat. No. 5,146,702 to Belokin, entitled,
Display Having An Electric Motor For Simulating A Flying Object;
U.S. Pat. No. 4,100,697 to Ward, entitled, Hoop Top; and U.S. Pat.
No. 5,823,844 to Markowitz, entitled, Interactive Vibrating
Toy.
[0007] A limitation associated with such prior art amusement
devices is the fact that the length of the flexible shaft is
constant. As such, the object supported by the flexible shaft is
restrained by the flexible shaft should that object attempt to move
away from or closer to the rotating base.
[0008] It has been found that an the path followed by a rotating
object is far more complex and interesting to observe if the length
of the shaft supporting that object is not held constant. It is
therefore an object of the present invention to provide an
amusement device where an object is held at the end of a rotating
flexible shaft that has a variable length. In this manner, the
object is free to move both toward and away from its rotating base
as part of its erratic movement.
SUMMARY OF THE INVENTION
[0009] The present invention is an amusement device used to move a
supported display object through an erratic path. The amusement
device includes a base element in which is disposed a rotating
assembly. The rotating assembly can be battery powered, spring
powered or manually powered. A support spring is used to
interconnect a display object to the rotating assembly in the base
element. The support spring has a first end and a second end. The
first end of the support spring is coupled to the rotating assembly
within the base element, wherein the support spring is rotated by
the rotating assembly. The remainder of the support spring extends
freely from the base element.
[0010] The display object is coupled to the second end of the
support spring. As the display object rotates, it causes the
support spring to at least partially elongate, thereby causing the
display object to move erratically from point to point.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] For a better understanding of the present invention,
reference is made to the following description of exemplary
embodiments thereof, considered in conjunction with the
accompanying drawings, in which:
[0012] FIG. 1 is a partially fragmented front view of a first
embodiment of the present invention amusement device;
[0013] FIG. 2 is a perspective view of the embodiment of the
present invention amusement device shown in FIG. 1;
[0014] FIG. 3 is a perspective view of an alternate embodiment of
the present invention amusement device; and
[0015] FIG. 4 is a perspective view of third alternate embodiment
of the present invention amusement device.
DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to FIG. 1, an exemplary embodiment of the present
invention device 10 is shown. The device is comprised of three
primary parts, which are a base 12, a display object 14 and a
support spring 16 that interconnects the display object 14 to the
base 12.
[0017] In the shown embodiment, the base 12 is configured as a pen.
However, such an embodiment is merely exemplary. The base 12 can be
most any hand-held object. Alternatively, the base 12 can be a
self-supporting structure that can rest on a flat surface. As such,
it should be understood that the appearance of the base 12 is not
important to the functioning of the overall device 10. The base 12
can be dedicated to the function of the overall device 10 or the
base 12 can have a secondary purpose outside the functioning of the
overall device 10, as does the pen illustrated. Alternate
embodiments of the base are later described.
[0018] Regardless of the appearance of the base 12, contained
within the base is rotating assembly 20. Preferably, the rotating
assembly 20 includes a motor 22, a battery 24 for powering the
motor 22 and an on/off switch 26 for controlling the operation of
the motor 22, as is shown in FIG. 1. However, in alternate
embodiments, the rotating assembly 20 can be a spring wound
assembly, a flywheel assembly, a manual crank assemble or any other
known means for providing rotational movement at a predetermined
point in an amusement device. The rotating assembly 20 rotates the
support spring 16 that extends from the base 12.
[0019] The motor rotates at a speed that is sufficient to cause
visible oscillations in the support spring 16. It is these
oscillations that cause the display object 14 to move in an erratic
pattern.
[0020] In the shown embodiment of the rotating assembly, the motor
22 turns a drive shaft 28. The drive shaft 28 terminates with a
connector coupling 30 that can be accessed externally from the base
12. As is shown, the motor 22 directly turns the connector coupling
30, via the drive shaft 28. However, it will be understood that
gearing can be present between the motor 22 and the connector
coupling 30 that alters the rotation rate of the connector coupling
30 with respect to the motor 22. Such gearing is well known and
used in the field of motorized toys.
[0021] The support spring 16 is coil spring having a relatively low
spring constant. The spring constant is selected so that the
support spring 16 is just capable of maintaining full compression
when stacked vertically with the weight of the display object 14
aligned vertically at its top. Once the support spring 16 is turned
away from a vertical alignment, the weight of the display object 14
bends the support spring 16 and pulls the support spring 16 away
from full compression.
[0022] The support spring 16 has two ends. One end of coupled to
the base 12 and the other end is coupled to the display object 14.
The support spring 16 preferably contains at least ten full
revolution between its two ends. The support spring 16, when laid
straight, is symmetrically coiled around a mid-line M. The spring
constant of the support spring 16 is selected so that when the base
12 is held in a vertical orientation, such as is shown in FIG. 1,
the weight of the display object 14 will cause the mid-line M of
the support spring 16 to bend between 90 degrees and 180 degrees
with respect the vertical. As such, the support spring 16 enables
the display object 14 to droop to the side when the base 12 is held
in a vertical orientation.
[0023] As has been stated above, the support spring 16 has two
ends. One end of the support spring 16 attaches to the connector
coupling 30 on the base 12. A connector may be present at the end
of the support spring 16 to facilitate attachment between the
support spring 16 and the connector coupling 30.
[0024] The opposite end of the support spring 16 terminates with
the display object 14. The display object 14 can be either
permanently affixed to the support spring 16 or detachable from the
support spring 16. A detachable configuration can be used in
assemblies where multiple display objects are available and a
person selects which of the display objects is placed upon the
support spring 16.
[0025] The display object 14 can be any item desired. However,
since the display object 14 will whirl around in an erratic
pattern, it is desired that the display object 14 have no sharp
points and be light in weight, so as to prevent injuries if the
display object were to inadvertently contact a person's face. An
exception to this general design parameter is when a propeller is
attached to the support spring as the display object. As a
propeller is rotated, the propeller creates thrust that acts upon
the support spring an adds additional movement to the already
erratic path of the display object.
[0026] However, in the shown embodiment, the display object 14 is
an eyeball made from photoluminescent plastic that enables the
eyeball to be viewed in the dark. It will be understood that the
display object 14 can be any object, such as an airplane, an
insect, a cartoon character or the like. The display object 14 can
also be a confection such as a hard candy.
[0027] Referring to FIG. 2, it can be seen that the support spring
16 is rotated by the motor 22 (FIG. 1) in the base 12. During
rotation, the inertia and centrifugal force created by the combined
mass of the support spring 16 and the display object 14, causes the
support spring 16 to elongate and the display object 14 to move
erratically. As the display object 14 moves, the support spring 16
stretches and retracts, thereby altering the length of the support
spring 16. The forces created by the deformed support spring 16
combine with the inertial and centrifugal forces to rapidly vary
the movements of the display object 14.
[0028] The display object 14 erratically moves to different points
throughout a possible range, which is shown by the circle in FIG.
2. The possible range is spherical in shape and is has a radius
equal to the stretched length of the support spring 16. If the
forces experienced by the support spring 16 are insufficient to
fully extend the support spring 16, the radius of the possible
range will decrease to the maximum length at which the support
spring is stretched.
[0029] Referring to FIG. 3, a variation of the present invention
device 40 is shown. In this embodiment, the base 42 is a
self-contained hand-held unit. The base 40 may even be a
pre-existing assembly, such as battery operated lollipop holder.
Battery operated lollipop holders are exemplified by U.S. Pat. No.
5,209,692 to Coleman, entitled, Combination Novelty Toy And A Candy
Holding Device, the disclosure of which is incorporated into this
specification by reference.
[0030] However, from FIG. 3, it can be seen that multiple support
springs 44 and multiple display objects 46 can be supplied. The
different support springs 44 can have different lengths, coil
diameters and spring constants. As such, each type of support
spring 44 will move in its own unique manner.
[0031] The display objects 46 also can be come in a variety of
sizes and weights. Since size and weight effect the path followed
by the display object 46, each type of display object 46 will have
its own unique movement characteristics.
[0032] Referring lastly, to FIG. 4, another embodiment of the
present invention device 50 is disclosed. In this embodiment, the
base 52 is a self-supporting assembly that can rest on a flat
surface and does not need to be hand-held. As such, the display
object 54 will whirl around the base 52 as the base 52 is left on a
surface. Such a configuration can be used as an advertizement
promotion to attract the attention of customers. Such a
configuration is also useful as part of a game, wherein a whirling
display object 54 is used to knock down objects or is used to
combat other whirling objects.
[0033] It will be understood that the various figures described
above illustrate only preferred embodiments of the present
invention. Features from the different embodiments can be mixed to
produce yet further embodiments. A person skilled in the art can
therefore make numerous alterations and modifications to the shown
embodiments utilizing functionally equivalent components to those
shown and described. All such modifications are intended to be
included within the scope of the present invention as defined by
the appended claims.
