This invention relates to apparatus for, and methods of, providing an opportunity for young children to hit and catch an element such as a ball. More particularly, the invention relates to apparatus for, and methods of, popping upwardly the element (e.g. the ball) upwardly in a substantially vertical direction to provide practice for a young child to hit the ball with a member (e.g. a bat) and for popping the ball upwardly with a horizontal component to provide practice for the child to catch the ball.
BACKGROUND OF THE PREFERRED EMBODIMENTS OF THE INVENTION
Baseball is a national pastime in the United States and in a number of foreign countries including Japan, Mexico, Cuba and the Dominican Republic. Children as young as 3 or 4 years old attempt to swing a bat against a ball or catch a ball. Parents and grandparents and older brothers and sisters attempt to help the child develop skills in hitting and catching a ball. The most common way of providing this help is to provide a T-ball stick disposed in a base member. The stick has at its upper end a cup for receiving and holding a ball. When the ball is disposed in the cup, the child swings a bat against the ball to propel the ball from the tee. To help a child in learning how to catch the ball, the ball is thrown gently by a parent to the child from a relatively short distance. At a more advanced age, the child practices batting by swinging the bat against the ball when the ball is thrown gently toward him from a relatively short distance.
In both hitting and catching, someone closely related to the child (e.g. a parent or grandparent) has to place the ball on the tee or throw the ball gently toward the child. This creates inconveniences, particularly when a young child in the age range of 3 to 6 years old is involved. In addition, the procedure is inefficient since considerable time is lost between the successive times that the ball is thrown gently to the child. This is particularly true when the number of balls used in the batting or catching practice is limited.
BRIEF DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
In a preferred embodiment of the invention, a transmitter in a member (e.g. bat) transmits signals when a switch on the bat is pressed. A pop-up apparatus receives the signals. A member in the apparatus prevents an element (e.g. ball) from being popped up in a first positioning of the member and provides for the element pop-up in a second positioning of the member. Normally disposed in the first position, the member is operable to the second position by the received signals. The apparatus includes a housing and a bin pivotally coupled to the housing to hold the element. The bin provides for a substantially vertical element pop-up in a first pivotal position and for a pop-up with a horizontal component in a second position. In the vertical pop-up, a player hits the ball with the bat. In the other pop-up, the player catches the ball.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
In a preferred embodiment of the invention, apparatus generally indicated at 10 (FIG. 1) is provided for popping an element (e.g. a ball 12) upwardly to provide practice to a young child (e.g. age 3 to 6 years) in hitting the ball with a propulsion member (e.g. a bat 14) or in catching the bail. Preferably the ball 12 is a hollow plastic ball having a
A switch 16 (FIG. 10) is provided on the bat 14, preferably at a position above the position on the handle portion where the batter's hands 18 (FIG. 1) grip the bat when the batter is swinging at the ball 12. The bat 14 may be made from a relatively thin hollow plastic material having a relatively light weight to facilitate the swinging of the bat by the child player and to prevent anyone from being injured if he or she should be struck by the bat. The switch 16 is depressed by the batter when the batter desires to have the apparatus 10 pop the ball upwardly. Although it is preferred to provide the switch 16 on the bat 14, it will be appreciated that the switch may be displaced from the bat without departing from the scope of the invention.
An oscillator generally indicated at 20 in FIG. 7 is disposed in the bat 14, when the switch 16 is on the bat, to provide for the transmission of signals to the pop-up apparatus 10 for obtaining a pop-up of the ball 12 by the pop-up apparatus. In one embodiment, the oscillator 20 may be crystal controlled for producing signals at a particular frequency such as approximately thirty-two megahertz (32 MHz). When the switch 16 is displaced from the bat 14, the oscillator 20 is correspondingly displaced. The signals from the oscillator 20 may be amplified as at 22 and the amplified signals may be introduced to an antenna 26 which may be provided with an impedance preferably matching the impedance of the amplitier 22. An energy source such as a battery 28 (FIG. 7) may be removably disposed in the bottom of the bat to energize the oscillator 20. The antenna and matching circuits 26, the amplifier 22 and the battery 28 may be disposed within the bat 14 when the switch 16 and the oscillator 20 are respectively disposed on and in the bat.
A receiver generally indicated at 32 in FIG. 8 may be disposed in the pop-up 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. Since the signals are transmitted by the antenna 26 and are received by the antenna 34, they may be transmitted on a wireless basis. The amplified signals may then be mixed as at 38 and the mixed signals may then be detected as at 40 to recover the signals at thirty-two megahertz (32 MHz).
The apparatus 10 includes a housing 44. The housing 44 is provided at its upper end with a stanchion 46 (FIG. 3). A sleeve 48 included in a ramp generally indicated at 50 fits snugly on the stanchion 46 in a removable relationship to the stanchion. The ramp 50 defines an inclined track 52 extending downwardly in a spiral path to a position at its bottom end above a hollow cavity 54. A plurality of the balls 12 are disposed on the track 52 for a movement of each ball in sequence into the hollow cavity 54 when the ball previously in the cavity is popped upwardly by the apparatus 10.
A bin generally indicated at 56 is pivotally coupled as at 58 (FIGS. 10 and 11) to the housing 44. In one pivotable position (FIG. 10) of the bin 56, each of the balls 12 is popped upwardly substantially vertically to provide for the batter to hit the ball with the bat 14. In another pivotable position (FIG. 1) of the bin 56, the bin is tilted downwardly so that the ball 12 moves in a direction having a horizontal component when the ball is popped upwardly. This provides for the ball 12 to be caught by the player as indicated by a glove 60.
The cavity 54 is defined by a pair of side walls 62 (FIG. 2) and a bottom will 64 (FIGS. 4-6, 10 and 11). The cavity 54 is disposed to receive the ball 12 after the ball moves from the ramp 50. Guides 66 are disposed at spaced positions between the side walls 62 and extend downwardly at progressive positions between the back and front of the bin 56 to direct the ball 12 downwardly from the hollow passage 54 toward The front of the cavity 60. An opening 68 is provided in the lop wall 65 between the guides 66 at the front end of the cavity 60. A bridge 70 (FIG. 2) extends upwardly from the side walls 62 in an arched configuration. The bridge 70 confines each successive ball 12 within the cavity 54 so that the ball cannot fall out of the cavity.
An actuating member 72 (FIGS. 4-6 and 10-11) is pivotally disposed at its rear end in the bin 56. The actuating member 72 extends forwardly through the bin 56 to the opening 68. A hammer portion 74 (FIGS. 4-6, 10 and 11) extends upwardly from the free (or right) end of the actuating member 72. The hammer portion 74 is preferably tapered at its upper end as at 76 so that the force exerted by the hammer portion on the ball 12 will be concentrated when the hammer portion impinges on the ball. In the normal or rest position (FIGS. 4, 6 and 10) of the actuating member 72, the free (or right) end of the hammer portion 74 extends upwardly through the opening 68 in the bin 56 and prevents the ball 12 in the cavity from moving to a position above the opening. When the free (or right) end of the actuating member 72 is pivoted downwardly so that the hammer portion 74 is below the opening 68 (FIGS. 5 and 10), the ball 12 moves forwardly in the cavity 54 to a position above the opening 68.
A manually operated switch 88 (FIG. 9) is disposed on the housing 44 to activate the pop-up apparatus 10 when the switch is manually closed. The switch 88 is connected in a circuit with a portable source of energy such as a battery 90 and with a motor 92 disposed in the bin 56. A normally open switch 94 (FIGS. 4-6 and 9) is connected in series with a low impedance 95 across the motor 92. The battery 90, the switch 88, the motor 92 and a switch 97 are in series. The switch 97 becomes closed when a coil 96 is energized by current from the oscillator or detector 40. When the switch 88 is manually closed and the switch 97 becomes closed as a result of the reception of signals by the receiver 32 and the production of signals by the oscillator and detector 40, a circuit is established which includes the battery 90, the switch 88, the motor 92 and the switch 97.
When energized, the motor 92 drives a planetary gear arrangement generally indicated at 95 (FIGS. 4-6). The planetary gear arrangement rotates a pinion gear 98 which in turn rotates a drive gear 99 in a counterclockwise direction in FIGS. 4, 5 and 6. A drive member 100 on the front side of the drive gear 99 rotates with the drive gear 99 and engages the left end of the actuating member 72, thereby causing the left end of the actuating member to rise as the gear 99 rotates. This causes the free (or right) end of the actuating member 72 to move downwardly. This may be seen by a comparison in the positioning of the actuating member 72 in FIGS. 4 and 5 of the drawings.
A constrainable member such as a helical spring 102 is operatively coupled to the actuating member at the left end of the actuating member. The spring 102 is disposed in an unconstrained relationship in FIG. 4. As the drive gear 99 rotates in a counterclockwise direction in FIGS. 4, 5 and 6, the drive member 100 operates on the left end of the actuating member 72 to displace the actuating member from the position shown in FIG. 4 to the position shown in FIG. 5. As a result of the displacement of the right end of the actuating member 72, the element 12 in the cavity moves from the position shown in FIG. 4 to a position above the opening 68 as shown in FIG. 5.
In the position shown in FIG. 5, the drive member 100 is at a position where it is no longer coupled to the left end of the actuating member 72. This causes the actuating member to move instantaneously from the position shown in FIG. 5 to the position shown in FIG. 6. As a result of this movement, the ball 12 is popped upwardly as shown in FIG. 6. The movement of the actuating member 72 to this position is limited by a stop member 103 as shown in FIG. 6.
There is a lug 104 on the back side of the drive gear 99. When the lug 104 impinges on a switch contact 108 (FIGS. 5 and 12), it drives the switch contact 108 against a contact 110 to close-the switch 94, which is defined by the contacts 108 and 110. This causes the motor 92 in FIG. 9 to be short circuited so that no energy is provided to the motor. The motor then decelerates and stops at a position where it is ready to be energized for another cycle of operation when the switch 16 on the bat 14 is again closed. The position of the lug 104 in the stop position of the motor 92 is shown in FIG. 6. The drive gear 99, the drive member 100 and the lug 104 may be considered to be included in a control mechanism generally indicated at 120, which is cyclically rotatable. The drive gear 99 may be considered as a rotary member in the cyclically rotatable control mechanism 120.
Although this invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for use in numerous other embodiments which will be apparent to persons of ordinary skill in the art. The invention is, therefore, to be limited only as indicated by the scope of the claims.
