## Background
FIELD OF THE INVENTION
The present invention relates to a portable batting device and method, and more particularly, to a portable batting device and method that launches a ball to a predetermined height within a hitting zone.
BACKGROUND OF THE INVENTION
Ball launching mechanisms or ejectors have been used for practicing many sports, including baseball, softball, volleyball, tennis, and soccer. For example, a volleyball launcher is disclosed in U.S. Pat. No. 5,575,482 by Bill Butler, Jr. The volleyball launcher includes a housing, a ball cradle, a lift rod, a cross bar and two propelling arms. The propelling arms are actuated by a stored energy mechanism. Movement of the propelling arms generates a launch impulse from a lift rod which propels a volleyball upwards.
A ball tossing device is disclosed in U.S. Pat. No. 5,590,876 by Joseph P. Sejnowski. The ball tossing device includes a base and a tossing mechanism. The tossing mechanism includes a foot pedal for manual operation and a remote release pedal for remote operation. The tossing mechanism also includes a launching tube, a launching member, a timer, and a batting tee. Depression of either pedal compresses a spring and retracts the launching member downwardly from the launching tube. Again depressing the same pedal causes the launching member to rapidly move upwardly, engaging a ball positioned in the launching tube, and tossing the ball.
A machine for practicing baseball batting is disclosed in U.S. Pat. No. 6,684,872 by Chien-Wen Kao and Yao-Hui Tang. The practicing machine includes a base and a popping device. The popping device includes a loading stand, a suspending stand, an accommodating chamber, a pressure cylinder, and a spring. The pressure cylinder and the spring are disposed within the loading stand. The accommodating chamber is disposed above the loading stand. The suspending stand supports the pressure cylinder. A baseball positioned in the accommodating chamber is launched vertically by actuation of the pressure cylinder and the spring.
The prior-art ball launching mechanism are relatively complicated in design, expensive to manufacture, and not easily transportable or usable. There is a need for a ball launching device that is economical to manufacture, portable, and easy to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Like elements have been given like numerical designation in the figures described below to facilitate an understanding of the present invention. With reference to the embodiments illustrated in FIGS. 1-2, portable batting device 10 may include housing 12. Housing 12 may have top side 14, bottom side 16, side walls 18 that interconnect top side 14 and bottom side 16, and interior compartment 19. Pneumatically operated ball launching assembly 20 may be partially disposed within interior compartment 19 of housing 12. Launching assembly 20 may launch ball 44 (e.g., T-ball, baseball, softball) upward into hitting zone 22 (shown in FIG. 4) so that a batter may attempt to hit ball 44 with a bat or other hitting instrument (e.g., T-ball bat, baseball bat, softball bat). Hitting zone 22 may be a predetermined and adjustable vertical height selected based on a number of factors such as the height of the batter or the height from the batter's knees and chest. Funnel-shaped ball capturing assembly 50 may be positioned on top side 14 of housing 12. Capturing assembly 50 receives ball 44 that the batter has swung at but missed hitting with the bat and thereafter funnels the ball into position for subsequent launch by launching assembly 20.
As seen in FIG. 1, launching assembly 20 may include air compressor 24, flow regulator 26, solenoid air valve 28, air exhaust 30, air accumulator 32, cylinder 34, and piston 36, all in fluid communication. Piston 36 may be positioned within cylinder 34. Piston 36 may have proximate end 38 and distal end 40. Distal end 40 of piston 36 may be the launching end of the launching assembly that extends external of top side 14 of housing 12 and contacts ball 44 in a launching position to launch ball 44 upward into hitting zone 22. Launching assembly 20 may also include ball retaining member 42 for supporting ball 44 in the launching position. As shown in FIG. 3, distal end 40 of piston 36 (i.e., the launching end of the launching assembly) may extend through an opening in ball retaining member 42 to the ball launching position at the upper surface of ball retaining member 42. In an alternate embodiment, the launching end of the launching assembly may be integrated with the ball retaining member such that the integral part is capable of moving to launch ball 44.
Referring again to FIGS. 1-2, capturing assembly 50 may include upper circular frame 52, lower circular frame 54, plurality of support bars 56, and ball funneling member 58 extending from upper circular frame 52 to lower circular frame 54. Plurality of support bars 56 may each be affixed to base plate 60 positioned on top side 14 of housing 12. Plurality of support bars 56 may each be straight or have one or more bends. Base plate 60 may have a central opening through which the launching end of the launching assembly extends. Ball funneling member 58 may be formed of a net attached to upper circular frame 52 and lower circular frame 54 as shown in FIGS. 1-2. Alternatively, ball funneling member 58 may be formed of upper surfaces of the plurality of support bars 56 alone (with no net) spaced such that a ball will not fit between two of support bars 56. Capturing assembly 50 may also include retaining frame 55 positioned above upper circular frame 52 and supported by plurality of retaining bars 57 connected to upper circular frame 52 and retaining frame 55.
Batting device 10 may also include ball sensor 62. Ball sensor 62 may be positioned proximate to ball retaining member 42. Ball sensor 62 may detect whether or not ball retaining member 42 is retaining a ball (e.g., ball 44). Ball sensor 62 may be an infrared light source mounted on one side of ball retaining member 42 and a corresponding light detector on the opposite side of ball retaining member 42.
Referring again to FIGS. 1-2, batting device 10 may also include ball feeding assembly 70. Ball feeding assembly 70 may include ramp 72, selective retaining pin 78, and ball counter 80. Ramp 72 may have proximate end 74 and distal end 76. Proximate end 74 of ramp 72 may be positioned over upper circular frame 52 of capturing assembly 50. Selective retaining pin 78 may be positioned at proximate end 74 of ramp 72. A plurality of balls (e.g., second ball 45, third ball 46, fourth ball 47, fifth ball 48, and sixth ball 49) may be supported by ramp 72. Ramp 72 may support fifty or more balls at once. Selective retaining pin 78 may prevent the plurality of balls from rolling into the capturing assembly 50 until desired. Ball counter 80 may count as each of the plurality of balls rolls over it on ramp 72.
Batting device 10 may further include battery 98. Battery 98 may be capable of powering batting device 10 such that it may be used outdoors without the use of an extension cord. Battery 98 may be positioned on one of side walls 18 of housing 12 as shown in FIGS. 1-2, on top side 14 of housing 12, or within interior compartment 19 of housing 12.
Batting device 10 in FIGS. 1-2 may also include a control system. The control system may include power switch 90 and switch box 92 positioned on side walls 18 of housing 12. Switch box 92 may include speed control 94, pause switch 95 and duration control 96. To initiate activation of device 10, power switch 90 may be switched to an “on” position. Speed control 94 may control the frequency of launching ball 44. Duration control 96 may control the length of time over which device 10 continues launching ball 44. Activation of pause switch 95 may prevent device 10 from launching ball 44 until pause switch 95 is deactivated. This may allow a user to stop device 10 from launching ball 44 without switching off power switch 90.
Power switch 90 may be composed of any type of on/off switch. Speed control 94 and duration control 96 may be composed of any type of switch, including proximity switches. Pause switch 90 may be a remotely controlled switch and device 10 may also include a remote control for activating the remotely controlled pause switch 90. Device 10 may also include a computer chip for electronically activating or adjusting the setting of power switch 90, speed control 94, duration control 96, and pause switch 90.
Engaging power switch 90 illustrated in FIGS. 1-2 may activate air compressor 24. Air compressor 24 may generate air pressure. The flow of compressed air through a tubular system (e.g., hoses or conduits) in launching assembly 20 may be controlled by flow regulator 26 and solenoid air valve 28. Compressed air may flow into air accumulator 32. When the air pressure in air accumulator 32 reaches a pressure greater than atmospheric pressure, compressed air may expand in cylinder 34. The expansion of air in cylinder 34 may vertically displace piston 36. As piston 36 is vertically displaced, distal end 40 of piston 36 travels through the central opening in base plate 60 and through the opening in ball retaining member 42. Distal end 40 of piston 36 vertically launches ball 44 as distal end 40 contacts ball 44 at the launching position (on the upper surface of ball retaining member 42). Device 10 may also include mechanism for controlling the height to which ball 44 is launched. This height control may be a valve that adjusts the amount of air flowing to cylinder 34, which in turn adjusts the height to which ball 44 is launched. Duration control 96 may be adjusted to control the duration of actuation of piston 36.
Batting device 10 may be configured to eject any type of ball that is capable of being hit with a bat such as baseballs, softballs, T-balls, etc. By way of example, the operation of device 10 illustrated in FIGS. 1-2 will now be discussed with reference to ejecting baseballs or softballs. The present invention is not limited to this operation.
Referring now to FIG. 4, batter 100 or any other person may first engage power switch 90, activating air compressor 24 in interior compartment 19 of housing 12. Compressed air may then flow through the tubular system of ball launching assembly 20 into air accumulator 32. Air pressure may build in air accumulator 32. Compressed air may expand into cylinder 34. Piston 36 may be vertically displaced by air expanding in cylinder 34. Distal end 40 of piston 36 may vertically launch ball 44 resting on ball retaining member 42.
Batter 100 may swing bat 102 attempting to hit launched ball 44 in hitting zone 22. If bat 102 does not hit ball 44 while in the air and ball 44 is not otherwise disturbed in its vertical path, ball 44 may fall into capturing assembly 50 due to the force of gravity. Once within assembly 50, ball 44 may roll down ball funneling member 58 and may come to rest in the launch position on ball retaining member 42. Retaining frame 55 and plurality of retaining bars 57 may prevent ball 44 from bouncing out of ball funneling member 58. Ball sensor 62 may detect that ball retaining member 42 is retaining ball 44. Ball 44 may be launched again upon the next actuation of launching assembly 20.
If bat 102 hits ball 44 while in hitting zone 22 or otherwise, or if ball 44 is otherwise disturbed in its vertical path such that ball 44 does not fall into capturing assembly 50, ball sensor 62 may detect that ball retaining member 42 is not retaining a ball in the launch position. After a predetermined time, ball sensor 62 may signal selective retaining pin 78 of ball feeding assembly 70 to release second ball 45 from ramp 72 and into capturing assembly 50. Second ball 45 may roll down ball funneling member 58 and may come to rest in the launch position on ball retaining member 42. As second ball 45 rolls down ball retaining member 42, third ball 46 may roll past ball counter 80 which counts third ball 46. Upon the next activation of launching assembly 20, second ball 45 may be launched from the launching position.
While preferred embodiments of the present invention have been described, it is to be understood that the embodiments described are illustrative only and that the scope of the invention is to be defined solely by the appended claims when accorded a full range of equivalents, many variations and modifications naturally occurring to those skilled in the art from a perusal hereof.
