Abstract
Abstract The present invention is concerned with a device for aiding the teaching and training techniques for hitting a baseball consisting of, a shirt to which is installed a flexible magnet within a tunnel to form a magnetic track which runs from the right front shoulder to the left front shoulder in an elliptical fashion; a baseball batting helmet with a chin strap attached thereto containing a magnetic sensor which contacts the magnetic track continuously as it travels from the right shoulder to the left shoulder as the batter swings at the ball; an alarm which notifies the batter of his position when he swings at the ball; an electrical power supply and means for connecting the power supply to the alarm and the magnetic sensor.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
A training device which can be worn by a user to teach the correct position when hitting a baseball comprising: a) a magnet means securing said magnet to a batter's body in an elyptical fashion such that said magnet extends across the batter's chest from the left shoulder to the right shoulder; b) a baseball batting helmet having a chin strap attached thereto and a magnetic sensor connected on said chin strap which contact said magnet running from said batter's right shoulder to said batter's left shoulder as said batter hits a baseball; c) an alarm; d) an electrical power supply of sufficient voltage to activate the alarm; e) means for connecting said power supply to said alarm system and said magnetic sensor.
Claim 2
Dependent Claim
123 words
A training device which can be worn by a user to teach the correct position when hitting a baseball comprising: a) a magnet means securing said magnet to a batter's body in an elyptical fashion such that said magnet extends across the batter's chest from the left shoulder to the right shoulder; b) a baseball batting helmet having a chin strap attached thereto and a magnetic sensor connected on said chin strap which contact said magnet running from said batter's right shoulder to said batter's left shoulder as said batter hits a baseball; c) an alarm; d) an electrical power supply of sufficient voltage to activate the alarm; e) means for connecting said power supply to said alarm system and said magnetic sensor.
Claim 3
Dependent Claim
31 words
A training device according to claim 1 wherein the magnet is secured within a tunnel to form a magnetic track running from the batter's right shoulder to the batter's left shoulder.
Claim 4
Dependent Claim
61 words
A training device according to claim 2 wherein the magnetic sensor connected to the chin strap detects the correct position of the head and shoulder as it moves from the batter's right shoulder to the batter's left shoulder along the magnetic track and transmit a signal to the batter by means of the alarm as he attempts to hit the baseball.
Claim 5
Dependent Claim
31 words
A training device according to claim 1 wherein the magnetic sensor connected to the chin strap contacts the magnet continuously from the batter's right shoulder to the batter's left shoulder elliptically.
Claim 6
Dependent Claim
13 words
A device according to claim 1 wherein the magnet is a flexible magnet.
Claim 7
Dependent Claim
14 words
A device according to claim 1 wherein the magnet is secured within a shirt.
Claim 8
Dependent Claim
40 words
A device according to claim 6 wherein the magnet is secured within a tunnel on the shirt to form a magnetic track running from the right front shoulder to the left front shoulder of the shirt in an elliptical fashion.
Claim 9
Dependent Claim
15 words
A device according to claim 1 further comprising a magnetic sensor with a protective shield.
Claim 10
Dependent Claim
24 words
A device according to claim 1 wherein the voltage of the power supply ranges from about 6 volts DC to about 12 volts DC.
Claim 11
Dependent Claim
18 words
A device according to claim 9 wherein the voltage of the power supply is about 9 volts DC.
Claim 12
Dependent Claim
26 words
A device according to claim 1 wherein the power supply is connected to the alarm and the magnetic sensor by means of an umbilical wire connection.
Claim 13
Dependent Claim
169 words
A training device which can be worn by a user to teach the correct position when hitting a baseball comprising: magnet and megnetic sensor means for securing said magnet to a batters body such that said magnet extends from a batter's right front shoulder to the batter's left front shoulder in an elliptical fashion, said magnet having sufficient energy to activate said magnetic sensor through an air space of up to one inch; a baseball batting helmet with a chin strap attached thereto said magnetic sensor being connected to said chin strap such that said air space between said magnetic sensor and the magnet is held substantially constant by the batter as said sensor is moved from the right shoulder to the left shoulder in an elliptical fashion thereby detecting the correct position of the batter's head and relative to his shoulder; an alarm; an electrical power supply of sufficient voltage to activate said alarm; and, means for connecting said power supply to said alarm and said magnetic sensor.
Claim 14
Dependent Claim
169 words
A training device which can be worn by a user to teach the correct position when hitting a baseball comprising: magnet and megnetic sensor means for securing said magnet to a batters body such that said magnet extends from a batter's right front shoulder to the batter's left front shoulder in an elliptical fashion, said magnet having sufficient energy to activate said magnetic sensor through an air space of up to one inch; a baseball batting helmet with a chin strap attached thereto said magnetic sensor being connected to said chin strap such that said air space between said magnetic sensor and the magnet is held substantially constant by the batter as said sensor is moved from the right shoulder to the left shoulder in an elliptical fashion thereby detecting the correct position of the batter's head and relative to his shoulder; an alarm; an electrical power supply of sufficient voltage to activate said alarm; and, means for connecting said power supply to said alarm and said magnetic sensor.
Claim 15
Dependent Claim
25 words
A device according to claim 12 wherein the magnet activates the magnetic sensor through an air space ranging from about 1/16 inch to 1/2 inch.
