Description




FIELD OF THE INVENTION




The present invention relates generally to the field of athletic training equipment. More particularly, the invention relates to a baseball training apparatus for projecting a ball or holding a ball in an elevated position so that the ball can be hit by a baseball bat.




BACKGROUND OF THE INVENTION




Baseball is a popular sport among all ages in today's society. One of the more challenging aspects to the sport of baseball, particularly for younger players, is swinging a bat to hit a ball that is tossed in the air. Hitting a ball, which is tossed into the air, is one of the most difficult activities to perform for young children with developing motor skills. In order to practice the skills required to hit a baseball, typically a minimum of two people, a pitcher and a batter, are required. In order to allow a single person to practice hitting, a number of conventionally known devices have been developed to suspend or project a ball in the air for hitting. These devices typically include a base having a ball support such as a tee. In tee devices, the ball is placed at the end of a vertically positioned tee where it is hit by a batter. These devices can also include contact levers which when hit by a bat strike and propel the ball positioned at the end of the tee. Other commercially known devices include a mechanism for projecting a single ball from a base. The projection mechanisms can include a strike pad that is manually hit by a user's bat or the user's foot to cause a single ball to be tossed in the air. Alternatively, the mechanism can be a ball support connected to a spring that is manually compressed and held in compression by a pin. When the pin is released, typically by a second user, the spring projects a ball into the air. Other mechanisms can include mechanical or mechanical/pneumatic assemblies that provide a container for a single ball and a time delay between the actuation of a pedal by the user and the projection of the single ball into the air. Other commonly known devices project balls sequentially over long distance in a generally horizontal direction.




Existing ball supporting or ball projecting devices have a number of drawbacks. First, existing ball projecting devices typically project only one ball after contact or actuation by the user. Therefore, the user must reload the device after each ball is projected and then manually re-actuate the device for each ball. This requires a single user to leave a ready batting position to re-actuate the device and then return to the batting position to strike the next ball. This repeated movement in and out of the ready batting position often disrupts the continuity of the batter's stance and swing, and can negatively affect the batter's concentration, particularly for the novice user. Second, many devices provide little or no time between the actuation of the device and the projection of the ball, thereby requiring the user to quickly reach a ready batting position following actuation of the device and then swing a bat at the ball. The lack of sufficient time between actuation of the device and ball projection increases the difficulty level of using the device and can promote poor batting stance and swing practices. Third, the known devices that provide a time delay between the actuation of a pedal by the user and the projection of a single ball into the air provide no warning to the user when the ball will be projected from the device. The lack of a warning signal allows users, particularly young children, to become distracted, leave the ready batting position or lose concentration. Existing ball projection devices for projecting multiple balls sequentially are large, expensive machines which project the balls in a generally horizontal direction and over long distance. Such devices can be unsafe and are not suitable for operation by children, particularly young children. Moreover, such devices are configured for professional use or for use by more advanced athletes.




Accordingly, it would be advantageous to provide a baseball training apparatus capable of holding a plurality of balls and projecting the balls in a generally vertical direction, one at a time at a predetermined time interval, following a single actuation signal. A plurality of single ball projections at a predetermined time interval between projections following a single actuation signal allows the user to establish a ready batting position and maintain that position during multiple swings of a bat. It also allows the user to develop continuity between swings, and more easily adjust his or her batting position. What is needed in part is a baseball training apparatus that provides the user with an audible warning signal that a ball is about to project from the apparatus. A warning signal will assist the user in concentrating and focusing on the ball just prior to the ball's projection. Also, it would be advantageous to provide a baseball training apparatus that is lightweight, inexpensive and easy to operate. Further, it would be advantageous to provide a baseball training apparatus that is durable, safe to use and suitable for outdoor use. What is also needed is a baseball training apparatus that is capable of adapting to the user's skill level. This can range from a tee ball mode of operation where a ball is positioned in a stationary and elevated position that aids the user in developing the initial batting skills to an automatic ball projection mode of operation where a plurality of balls are automatically projected upward one at a time over an extended duration for hitting by a user.




SUMMARY OF THE INVENTION




The present invention provides a baseball training apparatus for use with at least one ball. The baseball training apparatus includes a body, a drive assembly connected to the body, and a ball interface device. The drive assembly is configured to impart motion to the ball. The ball interface device is connected to the body. The ball interface device is configured for movement between a first position in which the ball engages the drive assembly and a second position in which the ball is prevented from engaging the drive assembly. A control system is operably coupled to the ball interface device. The control system interacts with the ball interface device such that the ball interface device changes between first and second positions at a predetermined time interval for a predetermined duration.




According to another aspect of the invention, a baseball training apparatus for use with at least one ball includes a control system applying a signal to a ball interface device at a predetermined frequency. According to another aspect of the invention, a baseball training apparatus for use with at least one ball includes a ball feeder tube removably connected to a body. The ball feeder tube is configured to hold the balls. A ball projection means is connected to the body. The ball projection means is configured for projecting a ball upward from the body.




The present invention also provides a baseball training set. The baseball training set includes a plurality of balls, a body, a drive assembly connected to the body, and a ball interface device.

102


insulates sound emitted from the drive assembly


20


during operation and limits the exposure of the rotating components of the drive assembly to only the outer foam covering


104


of the wheel


98


. This feature prevents potential injury in the event that a user, specifically a child, inserts an extremity (e.g. arm) through the ball inlet opening


62


or the ball outlet opening


64


of the cover


18


and into the apparatus


10


. The housing


102


is made of hard plastic, but other materials, such as wood and aluminum, can be used. Alternatively, the drive assembly

is positioned in a substantially horizontal position such that the arcuate member


97


supports the lowest ball and prevents the remaining balls


12


within the ball feeder tube


22


from continuing to travel into the apparatus


10


and from contacting the wheel


98


. In the second position, the bracket


95


pivots enabling the single ball


12


in contact with the arcuate member


97


to travel further along the ramp


36


and to contact the wheel


98


. Upon receipt of a signal from the control system


40


, the ball interface motor


103


is configured to transfer the bracket

22


is a magazine capable of holding up to five balls. Alternate magazine sizes are contemplated. The second end


114


of the tube


22


is sized to allow the ball


12


to freely exit the tube


22


. In an exemplary embodiment, the tube


22


is made of plastic, but other materials, such as wood, aluminum, etc., can be used.




Referring to

FIGS. 7 and 8

, in the tee ball mode of operation, the second end


114


of the tube


22


is removably inserted into the tee opening


88


of the cover


18


. The first end


112


of the tube


22


includes a concave support surface


120


for maintaining the ball


12


above the apparatus


10


. The first end


112


further includes a tapered section


122


positioned adjacent to and directly below the support surface

of the tube


22


is open and tapered to allow a ball to rest at the second end


114


of the tube


22


, when the tube


22


is in the tee ball mode of operation.




The apparatus


10


is configured principally for outdoor use, therefore the control circuit case


78


and the power supply case


66


are constructed to prevent moisture and debris from contacting the control system and the power supply


38


. The opening


56


(see

FIG. 3

) of the ramp


36


and the drain hole


32


(see

FIG. 6

) in the disk


24


allow water, such as rain water, that enters apparatus


10


through ball inlet opening or the ball outlet openings


62


,


64


(see

FIG. 2

) to drain out of the apparatus


10


. Additionally, the flange of the pushbutton


76


seals out water and debris from entering the apparatus


10


at the pushbutton opening


92


(see FIG.


5


). Additionally, the flange of the pushbutton

).




Referring to

FIG. 9

, a representative embodiment of the control system


40


circuit diagram is illustrated. Other circuit diagrams are available and would be known to a person of ordinary skill in the art. The microcontroller


72


includes internal integrated logic, an internal clock, memory for storing a timer event and a processor for comparing time to the value of the timer event. The microcontroller


72


is coupled to the pushbutton


76


, the power supply


38


, the motor


94


, the piezo-electric chip


74


and the ball interface device. The microcontroller


72


sends out positive voltage signals, according to the microcontroller's internal logic to a first transistor


126


connected to the motor


94


, a second transistor


128


connected to the piezo-electric chip


74


and a third transistor


130


connected to the ball interface device. The positive voltage signals cause the motor


94


, the piezo-electric chip


74


or the ball interface device to activate or re-position. The piezo-electric chip


74


emits a “beep” sound when actuated in order to warn the user that the ball


12


is about to be projected from the apparatus


10


. This is achieved without the need for adding speakers to the control system


40


. Thus, the piezo-electric chip


74


provides an inexpensive and effective warning signal function to the apparatus


10


. In an alternative embodiment, at least one audio speaker is included in the control system


40


for emitting audible warning signals or messages to the user.




Referring to

FIG. 10

, one exemplary embodiment of control system


40


integrated logic is illustrated. Other logic configurations are available, are contemplated, and would be known to a person of ordinary skill in the art. In an exemplary embodiment, as shown in

FIG. 9

, the control system


40


integrated logic begins with the pushbutton


76


. When the pushbutton


76


is not pressed, nothing will occur, as shown at block


200


. If pushbutton


76


is pressed, internal timer within the microcontroller


72


is activated, as shown at


202


, the motor


94


receives a signal from the microcontroller


72


to activate, as shown at


204


, and a timer event, stored in the microcontroller


72


, is set at a first predetermined duration. In an exemplary embodiment, the first predetermined duration is set at approximately seven seconds, as shown at


206


. Other duration settings can be used. The microcontroller


72


then determines if time equals the timer event (e.g., seven seconds), as shown at


208


. If time does not equal the timer event, nothing further will occur. If time does equal timer event, the microcontroller


72


sends a signal to activate the piezo-electric chip


74


, as shown at


210


. In an exemplary embodiment, the microcontroller


72


signal to the piezo-electric chip


74


causes the chip


74


to emit a beeping sound at an increasing frequency until the chip


74


is reset. The microcontroller


72


also resets the timer event to a value equal to the previous timer event value plus a second predetermined duration. In an exemplary embodiment, the second predetermined duration is approximately three seconds, as shown at


212


, but other duration settings can be used. The microcontroller


72


then determines if time equals the time event (e.g., ten seconds), as shown at


214


. If time does not equal time event, nothing further will occur. If time equals the timer event, the microcontroller


72


sends a signal to re-position the ball interface device, as shown at


216


. The microcontroller


72


signal to re-position the ball interface device holds the ball interface device in a repositioned state for a third predetermined duration equivalent to the time required for one ball


12


to the pass of the ball interface device and contact the wheel


98


. When the third predetermined duration expires, the ball interface device returns to its original position. In an exemplary embodiment, the third predetermined duration is approximately one quarter of a second, but other duration settings can be used. The microcontroller


72


resets the piezo-electric chip


74


, as shown at


218


. The microcontroller


72


also resets timer event to a value equal to the previous timer event value plus a fourth predetermined duration. In an exemplary embodiment, the fourth predetermined duration is set at approximately three seconds, as shown at


220


. Other duration settings can be used. The microcontroller


72


then determines if time is greater than a total cycle time. In an exemplary embodiment, the total cycle time is approximately thirty-four seconds, as shown at


222


. If time is not greater than thirty-four seconds, the microcontroller


72


returns to


208


and determines if time equals the time event and steps


208


through


220


are repeated. If time is greater than thirty-four seconds, the microcontroller


72


stops the motor


94


, as shown at


224


, stops the timer, as shown at


226


, and resets the timer event, as shown at


228


. This automatic shutdown feature of the control system


40


preserves the life of the battery


42


.




In summary, the control system


40


logic causes the apparatus


10


to function in the following manner. The user activates the apparatus


10


by pressing the pushbutton


76


once. Once activated, the control system


40


starts an internal timer and the motor


94


. The control system


40


then provides a seven second warm-up period for the user to attain a ready batting position. At seven seconds, the apparatus


10


emits a beeping sound that increases in frequency for three seconds until first ball is projected from the apparatus


10


at a total time of ten seconds, at which time the beeping sound stops. Also, at ten seconds, the ball interface device repositioned for approximately one quarter of a second allows a single ball


12


to pass the ball interface device and contact the wheel


98


. The beeping sound emitted by the apparatus


10


provides the user with an accurate warning signal of when the ball


12


will be projected from the apparatus


10


. Three seconds later, the apparatus


10


re-initiates the beeping sound for a duration of three seconds, at which time a second ball is projected from the apparatus


10


. This cycle repeats itself for a third, fourth and fifth ball. After the fifth ball is projected, the apparatus


10


automatically shuts down.




In the tee ball mode of operation, the second end


114


of the tube


22


is removably inserted into the tee opening


88


of the cover


18


. The ball


12


is placed on the first end


112


of the tube


22


for hitting with the bat


14


by the user. In the automatic ball projection mode of operation, the second end


114


of the tube


22


is removably attached to the ball inlet opening


62


and the bracket


116


. The user activates the apparatus


10


by pressing the pushbutton


76


, with a foot, a hand or the bat


14


. The apparatus


10


proceeds to emit a warning signal seven seconds later. The warning signal continues for three seconds at which time the ball interface device changes positions allowing the ball


12


to pass under the pin


110


of the ball interface device, and roll along the ramp


36


under the force of gravity until the ball


12


contacts the exposed portion of the wheel


98


. The wheel


98


imparts motion on to the ball


12


causing the ball


12


to travel along the rails


54


of the ramp


36


and continue upward and exit the apparatus


10


through the ball outlet opening


64


, where the ball


12


can be hit by the user. Three seconds later the warning signal reinitiates for a duration of three seconds at which time a second ball is projected from the apparatus


10


. The warning signal and ball projection cycle repeats for a third, fourth and fifth ball. After the fifth ball is projected by the apparatus


10


, the apparatus


10


automatically shuts down.
