Description




TECHNICAL FIELD OF THE INVENTION




The invention relates to a toy illuminated with a light to create unique visual illusions.




BACKGROUND OF THE INVENTION




Toys displaying visual effects, such as movement and light, are popular with children of all ages. Children enjoy playing with toys displaying visual effects, and adults delight in the enjoyment of children at play with such toys. Moreover, adults themselves can enjoy playing with amusing and entertaining toys displaying movement and light.




Light emitting diodes (LEDs) are light devices that have a longer user-life compared to filament light bulbs. LEDs also use less electrical energy, are usually smaller, and can flash more rapidly than filament light bulbs. LEDs can also exhibit various visual and optical effects involving different colors, blinking rates, and flashing patterns.




One aspect of human visual perception that has given rise to a number of optical effects devices is the phenomenon of visual memory. It has been known for several centuries that human vision displays a persistence phenomenon. This persistence phenomenon is based on the fact that humans retain visual images for a brief period after reception of the image.




This persistence phenomenon allows humans to ignore the hundreds of times per day their eyelids blink. Further, the persistence phenomenon eliminates the detection of the on-off electric light cycling, or flashing at rates of 60 Hz (e.g. cycles per second) or faster. Perhaps the most widely recognized and obvious example of the visual persistence phenomenon is motion pictures (movies), where still pictures flash upon a screen at a rate of 60 images per second. Because of the display rate, the visual persistence phenomenon allows such images to be perceived by humans as a seamless blend of continuous motion. Another example of the persistence phenomenon is human perception of a rapidly spinning wheel, which can appear to slow down, stop spinning, and even reverse direction at various rotation speeds. The visual refreshment rate is variable, but, in general, humans begin to perceive flickering images at about 24 Hz (e.g. 24 images per second).




A strobe light can also create a “stop motion” visual effect as it flashes bright light on visual scenes in rapid succession. Harold Edgerton, a scientist and photographer at the Massachusetts Institute of Technology, perfected a technique in 1931 for high-speed and stop-motion photography using strobe lighting. Photographs using this technique show such scenes as a bullet piercing an apple or a light bulb shattering. Strobe lighting is currently used at various entertainment events.




Well known children's toys include the use of animated cartoon characters and toy figures. Animated dolls and toy figures are almost universally found in a child's toy collection. Dolls and toy figures of all sizes displaying life-like movement have fascinated children for decades and remain very popular with children in a wide age range.




Various mechanisms have been used to impart movement to toy figures. These mechanisms range from purely manual mechanisms, such as strings on puppets, to purely mechanical, such as a wind-up spring mechanism. Attempts to use very complicated electro-mechanical designs in children's toys, including computer control technology, have been met with very limited success.




Imparting life-like movement in small toy figures has also proven to be very difficult, if not impossible. The smaller the figure, the more difficult it is to construct with an internal mechanism to impart movement. Moreover, a smaller figure dictates a smaller, and consequently more delicate, internal mechanism with a correspondingly higher breakage rate. Further, the constraints on movement schemes has limited the ability of toys to emulate life-like motion. There remains a need for new innovations and techniques to impart realistic movement in small toy figures. Moreover, there is also a present need to impart variable motion of a figure in a toy device.




SUMMARY OF THE INVENTION




The invention takes advantage of human persistence phenomenon to create a toy figure displaying realistic, life-like, and variable movements. The toy has a shaft or handle with at least one semi-flexible figure affixed to the top of the handle and a globe covering and surrounding the area where the figure affixes to the handle. An electric motor within the handle vibrates the affixed figure, and a light emitting diode (LED) strobe generator illuminates the toy figure at a specified flashing frequency.




The handle features a control for adjusting the LED strobe frequency, as well as an on-off switch for the electric motor and LED strobe light. Alternative embodiments allow the user to also control the rate and direction of the figure's movement, the intensity of the LED, a selection of LED combinations or color of LEDs, and a selection of different toy figures for movement in the toy device.




During operation, the electric motor causes the affixed figure on the handle to vibrate rapidly and become visually indistinct. The appendages on the figure in the toy device, as well the figure itself, vibrate and gyrate at a very high frequency. The LED illuminates the vibrating figure with an LED generated light source, and by adjusting the frequency of the LED strobe flashing, the strobe frequency and vibration frequency can be synchronized to induce a stop-motion or slow-motion visual effect. When in proper synchronization, the vibrating figure can be adjusted to vary the visual impression including an appearance of dancing or movement in a life-like manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIG. 1A

shows a side view of the external configuration of the invention. The toy device has a handle or shaft


5


. On the front of the handle


5


, there is an on-off switch


10


, and on the back, there is a thumb wheel


15


. On top of the handle


5


, there is an open-bottom, transparent globe


25


with hooks


30


to help hold the globe


25


in place.




The electrical components of the toy device are located inside the handle


5


. These components include a power source (batteries), the LED timing or strobe circuit, and the vibration assembly. An access cover


20


provides access to the interior of the toy device to allow easy replacement of the batteries. The on-off switch


10


selectively opens and closes the electrical circuit powering the toy device's vibration assembly and the LED strobe circuit. This switch is normally controlled by a user's index finger when held in its usual manner. The thumb wheel


15


on the back of the handle


5


connects to a frequency controller element, preferably a variable resistor, which adjusts the flashing or strobe frequency of the LEDs on the toy device. The handle


5


itself is constructed of plastic or some other light-weight, rigid or semi-rigid material.




The transparent globe


25


attached to the top of the handle


5


permits the user to view the figure, which is protected by the globe


25


. While the affixed figure can be viewed from many different perspectives or angles, a user holding the toy device will normally view the figure through the globe


25


from the backside of the toy device. The globe


25


has an open-bottom and may be secured to the handle


5


aided by the hooks


30


. Alternatively, the hooks


30


may be part of a friction fit or some other fastening mechanism for globe


25


, so the globe


25


can be selectively removed, providing access to the top of the handle


5


and permit the user to interchange a number of different figures.





FIG. 1B

shows a front view of the toy device. The front of the handle


5


includes the on-off switch


10


that controls the electric circuit located inside the handle


5


. This on-off switch


10


is normally operated by the index finger of the user. In normal usage, the front of the toy device faces away from the user.




A back view of the toy device is shown in FIG.


1


C. The handle


5


includes the thumb wheel


15


, which controls the LED strobe frequency. On the top of the toy device is an open-bottom, transparent globe


25


. Inside the globe


25


, there is a toy device

figure 50

attached to a vibration assembly mounted inside the handle


5


. While the figure can be viewed from many different angles, a usual viewing perspective of the figure is from the backside of the toy device. The hooks


30


on the side of the handle


5


help secure the globe


25


to the handle


5


.




In the embodiment described herein, the handle


5


will ideally be between 4.5″ to 5″ in length, 1″ to 1.25″ wide, and 1.5″ to 1.75″ in depth. The globe


25


will ideally be between 3″ to 4″ in diameter. Although not critical to the visual illusion of the invention, these dimensions provide a preferred base-line for the intended use of the toy device.




A top view of the handle


5


with the globe


25


removed is shown in

FIG. 2. A

platform stage


301


is the top surface of the handle


5


. In the center of the platform stage


301


is a circular opening


305


into the interior of handle


5


of the toy device. Extending from the opening


305


is a post


310


attached to the vibration assembly located inside the handle


5


of the toy device. The

figure 50

(not shown) can be attached to the post


310


securing the figure to the vibration assembly mounted inside handle


5


.




On the platform stage


301


are three light emitting diodes (LEDs)


315


,


316


, and


317


arranged in a 90° arc centered around the opening


305


. The LEDs


315


,


316


, and


317


emit the strobe light directed to the figure positioned on post


310


. By illuminating LEDs


315


,


316


, and


317


, the visual illusion of movement in the affixed

figure 50

(not shown) on post


310


is created. Although three LEDs


315


,


316


, and


317


in an arc provide good overall illumination in this embodiment, a different number of LEDs may be used. The LED(s) may illuminate the figure in an arc from as small as 30° relative to the center of the front of the figure to a full 360° arc. For example, eight LEDs could be arranged to completely illuminate the entire figure, or a number of arrays of two or more LEDs in different colors may be arranged around the figure Additional controls on the handle


5


can be used to control which combination of LED arrays illuminate, vary the angle of illumination, or vary the color of illumination.




The LEDs


315


,


316


, and


317


should be positioned between 0.75″ and 1.5″ , preferably between 1″ and 1.35″, from the figure to obtain the optimal visual effect of the illusion. Other configurations can be used in the toy device without departing from the spirit of the invention. For example, the distance of the LEDs can be varied to vary the visual illusion. One or more of the LEDs can also be elevated above the stage platform


301


. Moreover, LEDs can be placed on the globe


25


and direct light toward the figure from the front, side, or top of the globe


25


. The hooks


330


may also contain LEDs for illuminating the figure.




The outer edge


320


of the stage platform


301


is a raised lip or wall in which the open-bottom globe


25


fits. This outer edge


320


in the preferred embodiment is designed for permanently securing the globe


25


in place. Alternatively, this outer edge


320


may comprise screw-like threads or a surface enhancing a friction fit removably securing the globe


25


to the toy device. The hooks


330


also provide additional support and protection and enhance attachment.





FIG. 3A

shows a side view for an embodiment of a

figure 401

used in the invention. Viewed from the side, the

figure 401

is flat and made from a soft, semi-flexible material, such as rubber, which readily vibrates. The

figure 401

, however, may also be constructed of a rigid or semi-rigid material. A base


405


attaches to the post


310


(

FIG. 2

) securing the

figure 401

to the vibration assembly inside the handle


5


of the toy device.




A rigid metal or hard plastic mounting bracket


410


extends upwardly from the base


405


into the back of the figure


401


. The base


405


connects directly to the vibration assembly by the post


310


(

FIG. 2

) to impart the maximum amount of vibrating motion to the mounting bracket


410


. By attaching the mounting bracket


410


to the back of

figure 401

, the arms


415


and feet


417


, or any other appurtenances or appendages, freely respond to the vibration. Alternatively, the mounting bracket


410


can also be attached to other placements on the

figure 401

to vary the movement of the figure


401


.





FIG. 3B

is a front view of the figure


401


. The

figure 401

has two arms


415


and two legs


417


. The base


405


connects to the

figure 401

using a rigid mounting bracket


410


extending from the base


405


up to the mid-level of the back of the

figure 401

, where it attaches to the back of the figure


401


. During operation, the vibration from the vibration assembly causes the arms


415


and legs


417


to vibrate and gyrate along with rest of the body of figure


401


.




Other alternative embodiments for the

figure 401

include a base with multiple figures attached to the mounting bracket


410


or base


405


. Other whimsical objects, such as balls or rocketships, may be placed on the mounting bracket


410


or base


405


. A figure can also be used designed for viewing from a full 360° angle, with the mounting bracket


410


extending up through the bottom of the figure. Another embodiment can vary the type of movement of the figure to include slowly rotating the figure or rapidly twirling the figure The

figure 401

may also be permanently mounted, or the

figure 401

may be removably affixed allowing a multitude of figures to be attached to post


310


of the toy device. A flexible mounting bracket, such as a spring, may be used to dampen the vibration imparted to the figure


401


.





FIG. 4

shows a side sectional view revealing the interior of the handle


5


in the toy device. The handle body


501


is hollow and constructed of a rigid, or semi-rigid, light-weight material such as plastic. An electrical strobe circuit board


505


is mounted in the handle


501


. The thumb wheel


510


adjusts a frequency control element connected to the circuit board


505


by electrical connector


506


. The strobe circuit board


505


also connects to the LED


515


(or LED combination) by electrical connector


507


. Although only one LED


515


is shown, more than one LED can be connected with each other or in series to the strobe circuit board


505


.




The electrical circuit is also connected to a power source, such as two AA-size electric batteries, at electrical terminal


509


. The power source (not shown) are isolated from the actual internal electrical components and mechanism by a molded cavity or covering


530


. The electrical connector


526


connects the positive terminal


509


from the power source. An electrical connector


512


connects the ground terminal


508


of the batteries to the strobe circuit board


505


.




The electrical circuit and terminal


509


provide power to the vibration assembly


520


. The vibration assembly


520


mounts within the handle


501


using soft-mounts


521


that do not firmly anchor the vibration assembly to the handle


501


. This mounting configuration does not excessively restrict vibration. The mounting scheme surrounds the vibration assembly


520


with soft-mounts


521


to provide amble space for the vibration assembly


520


to impart vibration movement to the figure.




A post


523


extends upward from the vibration assembly


520


and fits into the base


405


(

FIG. 3A

) of the

figure 401

(FIG.


3


A). An on-off switch


511


selectively turns both the vibration assembly


520


and the strobe LEDs


515


on and off. Alternatively, a separate on-off switch or variable switch can also be provided for the vibration assembly


520


and the LEDs


515


.




The on-off switch


511


connects to the vibration assembly by electrical connector


522


and to the strobe circuit board


505


by electrical connector


528


. The on-off switch


511


also connects to the terminal


509


over electrical connector


526


.




In operation, the operator activates the on-off switch


511


to provide electrical power to the strobe circuit board


505


, LEDs


515


, and the vibration assembly


520


. The vibration assembly


520


consists of an electric motor rotating an off-center weight. When powered, the rotating off-center weight causes vibration. A figure (not shown) attached to the post


523


rapidly vibrates in response to the electric motor rotating the off-center weight and causing vibration of the post


523


in the vibration assembly


520


. The vibration frequency depends upon the mass of the rotating weight, the rotation speed of the motor, the mass of the character, the rigidity of the soft-mounts


521


, and the degree of freedom of movement within the handle


501


. Other types of vibration assemblies can be used and are contemplated by the invention. A variable control can also be used to modify the rate of vibration, and other controls can be added to control the direction of the figure's movement.




As a figure attached to the post


523


vibrates, the LEDs


515


illuminate the FIG. These LEDs


515


are positioned between 1″ and 1.25″ from the attached figure to achieve the optimal visual effect. The electrical circuit for the LEDs


515


includes the circuit board


505


, which produces an oscillating, pulsing electric current causing the LEDs


515


to intermittently illuminate and produce strobe lighting.




The thumb wheel


510


connected to the circuit board


505


by electrical connector


506


adjusts the frequency of the LEDs


515


illumination. Preferably, the thumb wheel


510


adjusts a variable resistor to vary the strobe frequency or, alternatively, the thumb wheel


510


may adjust a variable capacitor (not shown). The LEDs


515


in turn illuminate the figure, such as

figure 50

(

FIG. 1C

) and


401


(FIG.


3


A), with the variable frequency strobe light.




A toy device user can adjust the frequency of the strobe LEDs


515


using the thumb wheel


510


. By synchronizing the strobe frequency of the LEDs


515


with the frequency of vibration, a rapidly vibrating

figure 50

(

FIG. 1C

) or


401


(

FIG. 3A

) can be illuminated with the strobe lighting and create the illusion of variable movement. This visual illusion is the result of the persistence phenomenon of human vision.




Variable visual effects can be created by deftly varying the frequency of the flashing LEDs


515


. The vibrating illuminated

figure 401

(

FIG. 3A

) or


50


(

FIG. 1C

) can appear to be dancing or moving by varying the frequency of the strobe LEDs


515


using the thumb wheel


510


. Looking at

figure 401

(FIG.


3


A), the arms


415


and feet


417


can be made to appear to sway back and forth and up and down relatively slowly. Adjustment of the thumb wheel


510


can even “freeze” the

figure 401

(

FIG. 3A

) in place.




Alternative embodiments can also be used in the invention. A control can be added to control the speed of rotation of the electric motor, varying the vibration frequency of the vibration assembly


520


. Rather than rotating an off-center weight, the electric motor in the vibration assembly


520


may rotate an off-center cam which would vibrate the figure in a different manner. Although three LEDs


515


arranged in a 90° arc provide adequate illumination from a frontal aspect, more LEDs may be provided, including different colored LEDs to create different lighting effects. Moreover, an array of multiple LEDs


515


may be used to provide illumination over a greater aspect of the figure up to a full 360° range. Additional electrical components can also be added to provide sound and create one or more musical tunes.

Another alternative is to leave the strobe light frequency constant and adjust the vibration frequency to achieve the desired visual effects. Other alternate embodiments can include control over the direction of the figure's movement, the intensity of the LEDs, and different colored LEDs.
