Description




FIELD OF THE INVENTION




This invention relates generally to a children's toy, and, more particularly to, a ball launching and collection activity device.




BACKGROUND OF THE INVENTION




Various amusement devices that allow children to collect balls or to collect and reinsert balls into a device are known in the art. For example, it is known to provide a ball collection game where balls are blown upward from an apparatus and collected by a basket or other hand held device. Since the balls are air blown, they are typically small and light in weight. The user typically stands next to the apparatus so that he may collect the balls with the hand held device as they are blown from the bottom of the apparatus. If a ball is not collected, it will drop back into the apparatus. The apparatus continues to blow the balls until the user collects all of the balls.




It is also known to provide a ball collection game where the user attempts to shoot balls into a cylindrical opening. Once the ball is correctly inserted through the opening, it travels through the device and is released at the bottom of the device so that the user may continuously shoot the ball towards the opening.




Additionally, it is known to launch balls from a machine in an athletic environment. Athletic ball launching machines are used to assist the development of motor skills, such as hand—eye coordination, as well as to practice various athletic skills. For example, a tennis ball launching machine duplicates various shots, such as a lob or a line drive wherein the user practices his shot by returning the various shots towards the tennis ball launching machine. A baseball launching machine duplicates line drives, pop ups and grounders wherein the user may practice fielding the baseballs from the baseball launching machine. Thus, both the tennis ball launcher and the baseball launcher simulate various environments that enable the user to develop various athletic skills.




Athletic ball launching machines, however, typically include a flywheel mechanism that is used to launch a ball out of the apparatus. Often, the timing of the launching mechanism is offset and the balls become jammed within the flywheel launching mechanism potentially causing the mechanism to malfunction.




Additionally, the prior art ball launching apparatuses do not provide children with the opportunity to collect balls that are randomly launched away from the top of the apparatus and to insert the collected balls back into the apparatus.




Thus, it is desirable to create an improved ball collection and launching apparatus that enables children to develop motor skills as well as burn energy.




Accordingly, it is an object of the invention to provide a ball collection and launching apparatus that shoots balls out of the top of the device in various directions and at various speeds.




It is another object of the invention to provide a ball collection and launching apparatus that may be used simultaneously by a number of children.




It is yet another object of the invention to provide a ball launching device with minimal parts thereby reducing the manufacturing costs of the product.




These and other objects of the present invention, as well as the advantages thereof over existing prior art forms, which will become apparent from the description to follow, are accomplished by the improvements herein after described and claimed.




SUMMARY OF THE INVENTION




The present invention is directed to a ball launching device having an outer housing, a bowl and a launch assembly. The bowl and launch assembly are disposed in the outer housing. The bowl has a cone shaped wall and a vertical linear wall. The launch assembly is coupled to the bowl. The launch assembly includes a pulley energized by a motor that rotates the bowl. When the bowl rotates at a high speed, the cone shaped wall enables balls in the bowl to ascend up an inner surface of the bowl and propel out of the device.











The following detailed description of embodiments of the invention, taken in conjunction with the appended claims and accompanying drawings, provide a more complete understanding of the nature and scope of the invention.

25


. The bottom half


30


of the bowl


20


has a generally vertical linear wall


31


that has a scalloped lining


23


(see FIG.


3


). The vertical linear wall


31


leads to a cone shaped wall


27


that forms the top half


26


of the bowl


20


. The cone shaped wall


27


curves upwardly and outwardly from the vertical linear wall


31


resulting in an open upper end


29


. The cone shaped wall


27


of the bowl


20


follows the curve of the outer housing


12


. The bowl


20


also includes a curved lip


28


that extends downwardly from the cone shaped wall


27


of the bowl. The curved lip


28


is disposed adjacent to the top edge


15


of the outer housing

is positioned adjacent to the launch assembly


60


when the bowl is placed on the launch assembly


60


. The bottom surface of the bowl is mounted to the pulley of the launch assembly


60


by a plurality of fasteners, such as screws. The launch assembly


60


of the present invention will be discussed in greater detail with respect to FIG.


4


.




A cylindrical member


40


with a generally cone shaped top portion


42


is positioned near the bottom of the bowl. The cylindrical member


40


is positioned on a circular platform


44


. The circular platform


44


includes a notch or groove (not shown) adapted to receive an axle


70


extending from the center of the launch assembly


60


(see FIG.


4


). As a result, the circular platform


44


is affixed to the axle


70


. The axle


70


defines the center axis of the device. As such, the cylindrical member


40


and circular platform


44


are positioned at the center of the bowl


20


.




The circumference of the cylindrical member is smaller than the diameter of the bowl. As a result, when the cylindrical member


40


is positioned inside of the bowl


20


, a gap


50


is formed between the outer surface


41


of the cylindrical member


40


and the scalloped lining


23


adjacent to the vertical linear wall


31


of the bowl


20


.




The cone shaped top portion


42


of the cylindrical member


40


also includes a plurality of ears


43


extending from the top portion. The ears


43


are spaced an equal distance from each other. The ears flare outwardly towards the inner surface


22


of the bowl


20


. The cone shaped top portion


42


may be molded with the cylindrical member


40


or the cone shaped top portion


42


may be formed as a separate piece that is affixed to the top of the cylindrical member


40


.




The cylindrical member


40


, the cone shaped top portion


42


, the ears


43


, and the circular platform


44


are molded from a plastic, such as ABS.





FIG. 3

illustrates the inner surface


22


of the bowl


20


with the lining


23


preferably having a scalloped shape. Alternatively, the lining may have various curved patterns. The scalloped shaped lining


23


prohibits long cylindrical shaped foreign objects, such as pencils or pens, from ascending up the vertical linear wall of the bottom half of the bowl. As a result, the scalloped shaped lining prevents cylindrical shaped foreign objects from being launched out of the bowl.





FIG. 4

illustrates the launch assembly


60


of the present invention. The launch assembly


60


is enclosed within: the outer housing


12


of the ball launching device. The launch assembly


60


includes a casing


62


that houses a motor


64


, a belt


66


and pulley


68


. The casing


62


includes a cylindrical opening


63


in the center. The pulley


68


also includes a cylindrical opening


69


through the center of the pulley


68


. The pulley


68


is positioned within the casing


62


such that the opening


69


in the pulley


68


aligns with the opening


63


in the casing


62


.




The pulley


68


includes a groove


71


formed along the outer rim of the pulley


68


. The belt


66


is disposed in the groove


71


along the outer rim such that the belt


66


surrounds the pulley


68


. The belt


66


is powered by the motor


64


. As a result, when the motor is running, the belt transmits its energy to rotate the pulley


68


thereby also rotating the bowl


20


attached thereto.




The openings


63


and


69


in the casing


62


and the pulley


68


, respectively, house an axle


70


and at least one sleeve bearing


72


that is positioned around the axle


70


. The axle


70


is fixed to the casing such that when the pulley


68


rotates, the axle


70


remains fixed at the center of the casing


62


. The sleeve bearing(s)


72


allow the pulley


68


to rotate about the axle


70


with minimal friction between the axle


70


and the pulley


68


.




The casing


62


includes a battery compartment


74


for receiving batteries that provide power to operate the ball launching device. The casing


62


also includes a controller, such as a controller number W528510 by Windbond Electronics Corporation, that is in communication with the on/off button


76


, the motor


64


and a speaker


79


(see FIG.


5


).





FIG. 5

is a schematic drawing of the launch system of the present invention. The on/off button


76


is in communication with the controller


78


. Once activated, the controller


78


sends a signal to the speaker


79


and the motor


64


which rotates the belt


66


thereby rotating the pulley


68


and the bowl of the launching device.





FIG. 6

is a flow diagram that illustrates the system of the ball launching device. When the user engages the on/off button at


100


, electronic sounds will be emitted from the speaker at


110


to signify that the ball launching device has been activated. The motor then runs for 60 seconds as indicated at


120


. More specifically, during the first 10 seconds, the motor turns on for 2 seconds and then off for 0.5 seconds for four cycles. During the remaining 50 seconds, the motor is on continuously. After 60 seconds have passed, electronic sounds are again emitted from the speaker at


130


, and the ball launching device automatically shuts off at


140


.




Alternatively, if the on/off button is pressed twice at


100


and at


105


, the ball launching device would emit electronic sounds at


130


to signify that the device is going to shut off. Then, the ball launching device shuts off at


140


.




In use, the ball launching activity device of the present invention enables children to develop hand—eye coordination skills while burning energy. As illustrated in

FIG. 5

, once the on/off button


76


is pressed, the controller


78


activates the motor


64


. The controller


78


is programmed to run the motor at least 500 rpm. As the motor begins to run, the belt


66


attached thereto begins to rotate. Since the belt


66


is disposed in a groove


71


around the outer rim of the pulley


68


, the belt


66


transmits its energy to the pulley


68


so that the pulley


68


also rotates.




As discussed above, the bowl


20


is attached to the pulley


68


and the cylindrical member


40


located inside the bowl is affixed to the stationary axle


70


. As a result, when the pulley


68


rotates, it spins the bowl


20


. However, since the cylindrical member


40


is affixed to the stationary axle


70


, the cylindrical member


40


remains stationary inside of the bowl


20


. The casing


62


of the launch assembly


60


balances the rotating pulley and bowl attached thereto so that the device functions properly. The outer housing


12


of the ball launching device also remains stationary while the bowl


20


positioned therein rotates.




The ball launching device of the present invention launches balls


80


from the upper end


29


of the open bowl


20


. The balls


80


are made from a soft durometer plastic, such as EVA. The balls


80


may be placed in the device before it is activated or the balls


80


may be tossed into the bowl


20


while the device has been activated and the bowl


20


is spinning. If the balls


80


are in the device before it is activated, once the bowl


20


begins to rotate, the balls


80


start to bounce or jump around the inside of the bowl


20


. The cone shaped top


42


and the ears


43


of the cylindrical member


40


maintain the balls


80


within the top half


26


of the bowl


20


. Foreign objects that were laying on top of the balls or between the balls, however, fall between the ears


43


and into the gap


50


between the scalloped lining


23


against the vertical linear wall


31


of the bowl


20


and the cylindrical member


40


. As discussed above during the initial 10 seconds of the system of the ball launching device, the motor runs for 2 seconds and then is off for 0.5 seconds for four cycles. This ramp up process also causes the foreign objects to fall into the gap since the contents of the bowl shift each time the bowl starts to rotate after the 0.5 seconds of rest. As a result, the foreign objects that were located in the top half of the bowl are collected and remain trapped on the bottom surface


25


of the bowl


20


.




The bottom half


30


of the bowl


20


has steep vertical sides


31


which prevent foreign objects from moving up the scallop lining of the vertical sides of the bowl


20


when the bowl


20


is rotating. Thus, once a foreign object falls below the top half


26


of the bowl


20


into the area of the bottom half


30


of the bowl


20


, it becomes trapped on the bottom surface


25


of the bowl


20


. The foreign objects remain trapped on the bottom surface


25


of the bowl


20


until the objects are removed by the user, preferably an adult, from the bottom surface


25


of the bowl


20


when the device is shut off.




The balls, however, might temporarily rest in the gap


50


between the inner surface


22


of the bowl


20


and the cylindrical member


40


. The cylindrical member


40


is sized to define a gap


50


that is smaller than the diameter of the ball


80


to prevent the balls from falling to the bottom of the bowl. If a ball


80


becomes jammed in the gap


50


, however, the bowl


20


will stop rotating.




Once the bowl


20


is rotating at a sufficient speed, such as 500 rpm, the balls


80


disposed within the top half of the bowl ascend or climb up the cone shaped wall


27


of the top half of the bowl


20


. As the bowl


20


spins and the balls


80


therein revolve around the central axis defined by the axle


70


, a centrifugal force is created on the balls


80


inside the bowl


20


. As the balls climb the cone shaped wall


27


and approach the open upper end


29


and the lip


28


of the bowl


20


, the balls


80


are spun out of the bowl


20


.




The ball launching device of the present invention is capable of launching approximately 1-10 balls at the same time. The device launches the balls such that they land in a 360 degree area around the device. This provides the necessary randomness to maintain the interest of young children thereby entertaining the children playing with the ball launching device.




As discussed above, the device is pre-programmed so that the motor runs for 60 seconds and then shuts off. When the device shuts off, the children playing with the ball launching device are given an opportunity to gather all of the launched balls and place them into the bowl of the launching device in preparation for restarting the device.




While the preferred embodiment of this invention has been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the spirit of the invention, the scope of which is defined by the appended claims.
