Problems solved by technology

This is not practical because in the game of tennis the player has to anticipate the movement of the ball and prepare stance and begin back swing to strike the approaching ball precisely at the right time in a fluid motion.

Embodiment Construction

[0014] A Plexiglas tube 23 / 4 ID holding 18 tennis balls is inserted vertically into the top of the device. The balls fall, and there is room for three at a time going into the ball chute inside of the device. The remainder stay in the tube, falling into the device one at a time as a ball is ejected. The balls in the device compress the upper micro-switch lever, completing the circuit and allowing the circuit board to operate at such time as 120-volt power is applied. When the device is turned on the circuit board delays for 14 seconds, allowing time for the player to get into position. At that time the circuit board illuminates the first light, simulating that an opponent has struck the ball. One half second later the circuit board illuminates the second light, simulating that the ball is crossing the tennis net. One half second later the circuit board illuminates the third light, simulating that the ball is bouncing. At that time the circuit board provides power to a solenoid which...

Abstract

The device allows a beginner to learn the game, or an advanced player to develop new skills by simulating ball movement from the time that the opponent strikes the ball until the first bounce of the bail in the player's court. At this time a real ball is delivered at a speed and trajectory preset by the player. This simulation allows the practicing player to interact with the device in preparing stance and having a fluid back swing and swing of the tennis racket. The real ball having been struck by the player hits a large catch net located immediately in front of the device. The devise can be used in an enclosure the size of a one car garage or small basement, allowing use during rain or winter months.

Description

[0001] 1. Field of Invention[0002] This invention relates to a machine utilized for the practice of the game of tennis in small enclosures.[0003] 2. Prior Art[0004] Prior art practice machines for the game of tennis are designed to be used on a tennis court in good weather by throwing a tennis ball the length of a tennis court, over tennis net. By watching the ball approach, a practicing player can time his / her stance and back swing in anticipation of the arrival of the ball, U.S. Pat. No. 3,989,245, Augustine.[0005] Back swing and swing must be a fluid motion. Several machines are on the market, however all are designed to utilize a fill tennis court. Existing machines can be slowed down, placed close to the player, and deliver a ball representing the ball flight after the first bounce. This is not practical because in the game of tennis the player has to anticipate the movement of the ball and prepare stance and begin back swing to strike the approaching ball precisely at the righ...
