A member (e.g. baseball bat) including a switch manually operable to obtain the transmission of signals by a transmitter in the member to an apparatus for propelling an element (e.g. ball) toward an individual holding the member. The element is propelled by a propulsion mechanism in the apparatus toward the individual holding the member so that the individual can practice receiving the element (e.g. hitting the ball). The apparatus propels the element upon the receipt of the transmitted signals and prepares for the next element in the apparatus to be propelled upon a receipt of subsequent signals from the transmitter.
Description




BACKGROUND OF THE INVENTION




Many youngsters are interested in improving their skills in hitting a baseball. Because of this, machines have been provided on a commercial basis for pitching balls to a batter. The batter positions himself or herself in a batting cage and the machine then transmits a plurality of balls in sequence to the batter. The batter pays for this by inserting coins into a coin box or by paying a cashier.




There are at least three (3) problems with the arrangement described in the previous paragraph. One problem is that the batter cannot control when successive balls are propelled to the batter by the pitching machine. Another problem is that the batter has to travel to the site of the pitching machine, this being an inconvenience to the batter. A third disadvantage is that the pitching machines propel the balls at a high velocity toward the batter. This may be advantageous to teenagers and adults but it is not advantageous to pre-teenagers.




BRIEF DESCRIPTION OF THE INVENTION




This invention provides an apparatus for overcoming the disadvantages discussed in the previous paragraph. The apparatus of this invention provides for control by an individual (e.g. a batter) at times when a machine propels an element (e.g. a ball) for operation of a member (e.g. a bat) by the individual (e.g. batter). The apparatus of this invention is portable even by pre-teenagers so that the individual operating the member (e.g. the bat) can practice anywhere including the individual's backyard or a friend's backyard. The apparatus of this invention is especially designed to be used by pre-teenagers.




Although a pitching machine is shown in the drawings to be a preferred embodiment of the invention, it will be appreciated by persons of ordinary skill in the art that other embodiments are within the scope of the invention. For example, the apparatus of this invention can be adapted to propel hockey pucks to a player holding a hockey stick or to propel lacrosse balls to a player holding a lacrosse stick.




In one embodiment of the invention, a member (e.g. baseball bat) includes a switch manually operable to obtain the transmission of signals by a transmitter in the member to an apparatus for propelling an element (e.g. ball) toward an individual holding the member. The apparatus propels the element upon the receipt of the transmitted signals and prepares for a next ball in the apparatus to be propelled upon a receipt of a subsequent signal from the transmitter.




The element is propelled by the propulsion mechanism in the apparatus toward the individual holding the member so that the individual can practice receiving the element (e.g. hitting the ball).

DETAILED DESCRIPTION OF THE INVENTION




In one embodiment of the invention, apparatus generally indicated at


10


(

FIG. 1

) is provided for propelling an element (e.g. a ball)


12


toward a member (e.g. a ball) generally indicated at


14


., the force-imposing member (e.g. a bat)


14


having a first portion for manual grasping and movement by a player and a second portion for imposing a force on an element (e.g. a ball)


12


moving toward the member, wherein the first and second portions of the member are positioned in the direction of the elongation of the member, and the second portion of the member is wider than the first portion of the member. The ball


12


maybe a hard or a soft ball generally provided for baseball games. Preferably the ball is a hollow plastic ball having a light weight and constructed to limit the speed of the ball and the distance of travel of the ball. This ball is advantageous when the hitter is a child generally less than ten (10) years old.




A switch


16


(

FIG. 4

) is provided on the bat


14


, preferably at a position above the positions on the handle portion where the batter's hands


18


grip the bat when the batter is swinging at the ball


12


. The switch


16


is pressed by the batter when the batter desires to have the apparatus


10


propel the ball


12


toward the batter. The switch


16


is located between the first and second portions of the member in the direction of the elongation of the member.




A transmitter generally indicated at


20


in

FIG. 5

is disposed in the bat


14


to transmit signals to the pitching apparatus


10


for obtaining the propulsion of the ball


12


by the pitching apparatus toward the bat


14


. In one embodiment, the transmitter


20


may include an oscillator


22


for producing signals at a particular frequency such as approximately thirty-two megahertz (32 MHz). The oscillator


22


may be crystal controlled.




The signals from the oscillator


22


may be amplified at


24


and the amplified signals may be introduced to an antenna


26


which may be provided with an impedance preferably matching the impedance of the amplifier


24


. An energy source such as a battery


28


(

FIG. 4

) may be removably disposed in the bottom


30


of the bat to energize the transmitter


20


.




A receiver generally indicated at


32


in

FIG. 5

may be disposed in the pitching apparatus


10


to receive the signals transmitted from the bat


14


. The receiver


32


may include an antenna


34


which may be in the form of a coil. Amplifiers


36


may be provided to amplify the received signals. The amplified signals may then be mixed at


38


and the mixed signals may then be detected as at


40


to recover the signals at thirty-two megahertz (32 MHz). The detected signals may then be introduced to a driver


42


.




The apparatus


10


includes a base member


50


(

FIGS. 1-3

) and a housing


52


pivotably attached to the base member as at


54


. The base member is adapted to be supported on a support surface such as the ground. The base member


50


is adapted to hold a transportable energy source such as a battery


56


.




The housing


52


is provided with a hollow passage


58


. Holes


60


may be provided in the housing


52


at progressive positions along the passage


58


, primarily for aesthetic purposes. The ball


12


is adapted to be disposed in the hollow passage


58


against a plurality of annularly spaced fingers


62


in a rotatable detainer


64


having a shape such as a star wheel. The detainer


64


is normally engaged by a release mechanism


65


which is actuated to be withdrawn from engagement with the detainer when a solenoid


66


is energized.




The hollow passage


58


is initially disposed vertically and is progressively curved at progressive downward positions to have a horizontal disposition. A pair of pockets


70


are disposed in the housing


52


at the opposite sides of the housing at positions where the hollow passage


58


is substantially horizontal. Two (2) motors


74


are provided, one disposed in one of the pockets


70


and the other disposed in the other one of the pockets


70


. Two (2) actuators are provided, one disposed in one of the pockets


70


and the other disposed in the other one of the pockets


70


.




The motor


74


and the roller


76


in each pocket


72


are operatively coupled to each other to provide a rotation of the roller in accordance with the energizing of the motor. The rollers


76


are preferably made from a resilient material and are preferably extended into the hollow passage


58


to grip the opposite ends of the ball


12


in the passage and to propel the ball from the passage in accordance with the rotation of the rollers. The motors


74


and the rollers


76


may be considered as a propulsion mechanism.




The battery


56


and the motors


74


are disposed in a series circuit (

FIG. 6

) with a normally open switch


78


. The switch


78


becomes closed when the ball


12


is disposed on the finger


62


of the detainer


64


. The closure of the switch


78


at such time results from the fact that each finger


62


has some play in its positioning. This causes each finger


62


to be disposed upwardly, with no ball on the finger, from the position which it occupies when the ball


12


is disposed on the finger. In the upward position of the finger


62


, the switch


78


is open.




In this way, the motors


74


are energized only when the ball


12


is in the hollow passage


58


in a position to be propelled from the hollow passage when a signal from the transmitter


20


is received by the receiver


32


. Furthermore, energy is conserved in the battery


56


to prolong the life of the battery since the battery provides energy to the motors


74


only when the ball


12


is disposed in the hollow passage


58


.




The housing


52


is provided at its top end with a stanchion. A tube


82


forming a part of ramp generally indicated at


84


fits snugly on the stanchion in a removable relationship to the stanchion. The ramp


84


defines an inclined track


86


extending in a spiral path to a position at its bottom end above the hollow passage


58


. A plurality of the balls


12


are disposed on the track


86


for a movement of each ball in sequence into the hollow passage


58


when the ball previously in the hollow passage is propelled by the rollers


76


from the passage toward the batter holding the bat


14


.




Assume that the ramp


84


is disposed on the stanchion at the top of the housing


52


and that one of the balls


12


on the track


86


has dropped into the hollow passage


58


for disposition on the finger


62


extending into the hollow passage. This causes the finger


62


on the detainer


64


to be positioned to close the switch


78


in FIG.


6


and the motors


74


to be energized. The resultant rotation of the rollers


76


provides for the propulsion of the ball from the hollow passage


58


when the ball is released by the detainer


64


.




When the batter manually closes the switch


16


in

FIG. 4

, signals are transmitted by the transmitter


20


in

FIG. 5

to the receiver


32


in FIG.


5


. This causes the solenoid


66


(

FIG. 3

) to be energized and the release mechanism


65


to be retracted from the detainer


64


. The detainer


64


is now free to be rotated in a counterclockwise direction by the ball


12


on the finger


62


. This rotation frees the ball


12


to move downwardly in the hollow passage


58


to a position between the rollers


76


. Since the rollers


76


are already being rotated by the motors


74


, the rollers propel the ball


12


from the hollow passage toward the batter when the ball reaches the rollers. When the ball


12


is dropping through the hollow passage


58


, the next ball on the track


86


drops into the hollow passage for disposition against one of the fingers


62


.
