Apparatus for, and method of, positioning movable elements on a T-ball mechanism for propulsion
A propulsion member (e.g. a bat) has an external switch and an internally disposed transistor which transmits signals when the switch is manually closed. A receiver in a tee mechanism receives the signals and causes a tee in the mechanism to move upwardly from a rest position to an operative position. As the tee moves upwardly to the operative position, an element (e.g. a wiffle ball) moves on a ramp to a supportive position at the top of the tee. When the tee is in the operative position, a player holding the propulsion member swings the member against the ball. This is helpful to young children (e.g. eight (8) years old or younger) in learning how to hit a baseball.
This invention relates to systems for, and methods of, providing a tee mechanism including a tee on which a ball can be disposed so that a child can practice hitting the ball with a bat. More particularly, the invention relates to a system for, and method of, controlling a disposition of a ball on a tee in accordance with the transmission of signals from the bat under the control of the child holding the bat.
BACKGROUND OF THE PREFERRED EMBODIMENTS OF THE INVENTIONBaseball has been designated for years in the United States as the national pastime. Actually, baseball constitutes the national pastime in a number of countries in the world including Japan and the countries in Central America. The fundamentals of baseball are in two (2) categories—hitting and catching. Hitting is perhaps more difficult than catching. Pitching machines have been in existence for decades to provide an opportunity for baseball players to practice hitting. When activated, the machines propel balls to a batter who stands in a batting cage. The balls are propelled on a sequential basis to the batter at a relatively high speed.
U.S. Pat. No. 6,190,271 issued on Feb. 20, 2001 to Mark J. Rappaport and Jose E. Leal as joint inventors and licensed to the same licensee as the licensee of this patent application discloses and claims a system for, and method of, propelling balls to a batter, who is primarily a youngster between the ages of about 9 to 12. The system and method disclosed in U.S. Pat. No. 6,190,271 provide a bat with a switch on the bat and a transmitter in the bat. When the batter presses the switch to close the switch, the transmitter sends signals to a propulsion mechanism. The propulsion mechanism then propels a ball toward the batter. The ball is preferably a wiffle type of ball so that it will not travel a long distance when hit and so that a bystander will not be injured if struck by the ball.
Special formats have been specially developed for young children (e.g. children below the age of about nine (9) years old) to help them practice hitting a baseball. In these special formats, a softball is disposed on the top of a tee which extends upwardly from a support surface. A child then swings a bat against the ball to hit the ball. Leagues have been formed with a plurality of teams each having a particular number of players eight (8) years old or younger.
BRIEF DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTIONIn a preferred embodiment of the invention, a propulsion member (e.g. a bat) has an external switch and an internally disposed transmitter which transmits signals when the switch is manually closed. A receiver in a tee mechanism receives the signals and causes a tee in the mechanism to move upwardly from a rest position to an operative position. As the tee moves upwardly to the operative position, an element (e.g. a wiffle ball) moves on a ramp to a supportive position at the top of the tee. When the tee is in the operative position, a player holding the propulsion member swings the member against the ball. This is helpful to young children (e.g. eight (8) years old or younger) in learning how to hit a baseball.
BRIEF DESCRIPTION OF THE DRAWINGSIn the drawings:
The bat 20 may be conventional. It has a narrow portion 22 for gripping by the hitter and it has an expanded portion 24 for impact with the ball 12. A manually operated switch 26 is disposed on the bat 20, preferably between the gripping portion 22 and the hitting portion 24. A transmitter 28 (
The tee mechanism 16 includes a housing 33 within which the tee 14 is disposed. The tee 14 in the tee mechanism 16 constitutes an elongated rod which preferably extends in a substantially vertical direction. The tee mechanism 16 includes a base 35 on which the tee 14 is supported. A rack gear 34 (
Ramp members 46a and 46b are provided to hold a plurality of the wiffle balls 12 in a stacked relationship. A movable detent 48 is provided at a leading position in the ramp 46a (
The circuitry for operating the motor 38 is generally indicated at 50 in
When the batter 18 desires to hit one of the wiffle balls 12, the batter presses the switch 26. This causes the circuit 32 in
The switch 62 then closes and the switch 56 opens. This causes the tee 14 to move upwardly. When the tee 14 reaches a position corresponding to that indicated in
The batter 18 may subsequently wish to hit another ball. The batter then closes the switch 26 to provide for the transmission of signals to the tee mechanism 16. The tee 14 then moves downwardly to the bottom position and thereafter upwardly to receive the next one of the wiffle balls 12 in the ramp 46a. In this way, the batter 18 is able to practice his hitting with wiffle balls 12 which, even when hit well, do not travel far so that they can be easily retrieved and used again. Furthermore, the wiffle balls 12 do not injure any bystander.
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.
