Abstract

An automatic batting tee apparatus includes a housing having a top opening, a chute for feeding balls one at a time to above the top opening, a drive member mounted upright in the housing for rotation about a vertical axis aligned with the top opening, and a tube disposed upright in the housing surrounding the drive member and aligned with the top opening. The tube is drivingly engaged with the drive member and coupled to the housing so that in response to rotation of the drive member in one and the other of opposite rotational directions the tube will undergo upward and downward reciprocal movement along the vertical axis relative to the rotating drive member through a ball receiving and positioning cycle. The apparatus also includes drive means for rotating the drive member in the one and other rotational directions to cause reciprocal movement of the tube through the ball receiving and positioning cycle, and drive control means for actuating the drive means to cause rotation of the drive member and reciprocal movement of the tube through the ball receiving and positioning cycle.

(e) drive means for rotating said drive member in said one and other of said pair of rotational directions to cause reciprocal movement of said tube through said ball receiving and positioning cycle.

2. The apparatus of claim 1 wherein said housing includes:

a base for resting on the ground; and

an enclosure supported at a bottom end portion on said base and extending upright therefrom to an open top end portion of said enclosure.

3. The apparatus of claim 2 wherein said enclosure includes:

an annular sidewall having said open top end portion; and

a top cover fitted over said open top end portion of said annular sidewall and defining a track extending in an inclined orientation from a side opening in said top end portion of said sidewall to an top opening in said top cover defining said top opening of said housing.

4. The apparatus of claim 1 wherein said ball feeding means includes a ball feeder chute mounted to said housing and extending inclined outwardly and upwardly therefrom, said chute having a discharge end located adjacent to said top cover.

5. The apparatus of claim 4 wherein said ball feeding means also includes a ball dispensing element pivotally mounted at a discharge end of said chute for undergoing movement from an upright ball-blocking position to a depressed ball-releasing position and back to said upright ball-blocking position so as to permit discharge of only one ball at a time from said chute to above said top opening of said housing during each ball receiving and positioning cycle.

6. The apparatus of claim 1 wherein said drive means includes:

an electrical power source;

an electric motor having a rotary drive shaft and being connected to said electrical power source; and

a drive motion transmission coupling drivingly interconnecting said rotary drive shaft of said electric motor to said drive member such that rotation of said rotary drive shaft of said electric motor causes rotation of said drive member.

7. The apparatus of claim 1 further comprising:

drive control means for actuating said drive means to cause rotation of said drive member and reciprocal movement of said tube through said ball receiving and positioning cycle.

8. The apparatus of claim 7 wherein said drive control means includes an activation element in the form of a transducer disposed on said housing and adapted to generate an electrical signal in response to the user striking said transducer.

9. The apparatus of claim 8 wherein said drive control means further includes a location sensing mechanism positioned adjacent to said tube and being operable to sense the arrival of said tube at vertically spaced lower and upper positions at which said tube terminates and changes direction of its reciprocal movement through said ball receiving and positioning cycle.

10. The apparatus of claim 9 wherein said drive control means also includes an electrical timer operable to cause a pause in operation of said drive means and thereby a pause in the rotation of said drive member and in the reciprocal movement of said tube when said tube reaches said lower position in order to permit transfer of a ball from said discharge end of said chute to above said top opening of said housing.

11. The apparatus of claim 10 wherein said drive control means further includes an electronic controller programmed to control operation of said timer and said drive means in response to the position of said tube sensed by said location sensing mechanism and in response to activation of said transducer by the user.

12. An automatic batting tee apparatus, comprising:

(a) a housing having a top opening;

(b) means for feeding balls one at a time to above said top opening of said housing;

(c) an elongated drive screw member mounted upright in said housing for rotation in one and the other of a pair of opposite rotational directions about a vertical axis aligned with said top opening of said housing, said drive screw member having external screw threads;

(d) an elongated tube disposed upright in said housing surrounding said drive screw member and aligned with said top opening of said housing, said tube having a lower end with internal screw threads threadably engaged with said external screw threads of said drive screw member;

(e) guide means in said housing for engaging said tube so as to prevent rotation of said tube with rotation of said drive screw member and in response to rotation of said drive screw member in one and the other of a pair of opposite rotational directions guide upward and downward reciprocal movement of said tube along said vertical axis relative to said rotating drive screw member through a ball receiving and positioning cycle in which, as said drive screw member rotates in said one rotational direction, said tube is lowered to a ball receiving position for receiving and supporting a ball on said upper end of said tube and then, as said drive screw member rotates in said other rotational direction said tube is raised to move said upper end of said tube supporting the ball through said top opening of said housing for positioning the ball in a ball hitting position spaced above said housing;

(f) drive means for rotating said drive screw member in said one and other of said pair of rotational directions to cause reciprocal movement of said tube through said ball receiving and positioning cycle; and

13. The apparatus of claim 12 wherein said guide means includes:

a guide member stationarily mounted upright in said housing laterally from and adjacent to said tube and having an elongated groove extending between upper and lower ends of said guide member; and

a guide element attached to said tube and extending laterally therefrom into said groove defined in said guide member so as to prevent rotation of said tube upon rotation of said drive screw member and thereby cause said upward and downward reciprocal movement of said tube relative to said drive screw member through said ball receiving and positioning cycle.

14. The apparatus of claim 12 wherein said housing includes:

an electrical power source;

an electric motor having a rotary drive shaft and being connected to said electrical power source; and
