Abstract

A tennis training simulation system is disclosed that improves both reaction time and ground stroke techniques within a limited physical training environment. This training system combines simulated service of a tennis ball from a service line over a virtual net, and delivery of real tennis ball to an awaiting tennis student. In the system of this invention, the tennis ball delivery system includes an automatic tennis ball machine equipped with an array of lights or LED'"'"'s that simulate the service of a tennis ball from a service line, a simulated trajectory of the tennis ball over a virtual net, and a simulated first bounce of a tennis ball coupled immediately thereafter with real in-flight delivery of an actual tennis ball to an awaiting tennis student.

Claims

1. In a tennis training simulation system which includes an array of lights or LED'"'"'s to denote the flight of a tennis ball, the improvement comprising:

An automated tennis ball delivery machine which includes a console having an array of visible indicators in a defined sequence relative to one another and positioned on a forward facing panel of said console,

A ball chute within said console for feeding of tennis balls, one at a time, to an impeller means for bounceless delivery of a single tennis ball from said ball chute to an awaiting tennis player, said ball chute being further provided with gating means for control of passage of a tennis ball along said ball chute and activation means, associated with said gate, to open and close said gate,

Timer means for coordinated control of movement of a tennis ball along said ball chute and for sequential activation of said visible indicators within said array, and

Impeller means for delivery of a tennis ball from said ball chute to an awaiting tennis player upon illumination of the last of said indicators within said indicator array.

2. The tennis training simulation system of claim 1, wherein said array of indicators comprises a series of lights or LED'"'"'s that can be sequentially activated in response to a timed pulse.

3. The tennis training simulation system of claim 1, wherein said impeller means comprises a pair of counter-rotating wheels positioned at the end of the ball chute.

4. The tennis training simulation system of claim 1, wherein said console further includes means for supplying tennis balls to said ball chute, said ball supply means including means for visual observation of the contents of ball supply means.

5. The tennis training simulation system of claim 1, wherein said timer means includes a programmable module and means for selection from among training system routines stored within said module.

6. The tennis training simulation system of claim 1, wherein said gating means including a solenoid activated reciprocating member for release of a tennis ball, one at a time, along said ball chute.

7. The tennis training simulation system of claim 1, wherein said ball chute further includes at least two sensors to detect the relative position of a tennis ball as it advances along said ball chute.

8. In a tennis training simulation system which includes an array of lights or LED'"'"'s to denote the flight of a tennis ball, the improvement comprising:

An automated tennis ball delivery machine which includes a console having an array of visible indicators in a defined sequence relative to one another and positioned on a forward facing panel of said console,

A netting located between said tennis ball delivery machine and a player,

A ball chute within said console for feeding of tennis balls, one at a time, to an impeller means for bounceless delivery of a single tennis ball from said ball chute to an awaiting tennis player, said ball chute being further provided with gating means for control of passage of a tennis ball along said ball chute and activation means, associated with said gate, to open and close said gate,

Timer means for coordinated control of movement of a tennis ball along said ball chute and for sequential activation of said visible indicators within said array, and

Impeller means for delivery of a tennis ball from said ball chute to an awaiting tennis player upon illumination of the last of said indicators within said indicator array.

9. The tennis training simulation system of claim 8, said netting having aperture means to allow ball delivery to said player.
