## Abstract

A swing training device and system that includes a sequence of LED lights that are used to simulate the movement of a pitched ball along a horizontal line and act as a cue for initiating a swing. The swing training device will help develop visual skills by using the eyes to track a light source along a path to the ball such that a bat or striking object hits the ball at the same time the moving light intersects or passes over the ball. The light carrying cable is of a durable design so that the user may practice with the game used bat.

## Claims

### Claim 1

In a swing training device consisting of:
a first horizontal member having a proximate end and a distal end, the distal end adapted for attaching to a substantially rigid frame;
an object assembly comprising an object located below the proximate end of the first horizontal member;
a first line having a first segment extending substantially along a vertical axis defined through a center of the object assembly and coupled to the proximate end of the first horizontal member, the first line having a second segment extending substantially along the vertical axis below the object assembly and coupled to the proximate end of second substantially rigid horizontal member, wherein the distal end is attached to the substantially rigid frame, the first line having a first end coupled to a top side of the object assembly and a second end coupled to a bottom side of the object assembly;
a second line that extends substantially perpendicular to the first line in a longitudinal direction substantially along a path of the object defining a horizontal axis, the second line having a proximate end coupled to the object assembly and a distal end coupled to a third substantially rigid member operatively connected to the sides of the rigid frame;
a V-shaped third line having a first end, a second end, and a cusp there between, the V-shaped third line being located substantially in the vertical plane, the first end of the third line is coupled to the first end of the first line, the second end of the third line is coupled to the second end of the first line, and the cusp is coupled to the proximate end of the second line; wherein the vertical axis defined through the centerline of the object assembly and the horizontal axis define a vertical plane, the object assembly having a vertical bore that extends through the vertical axis and a fourth line located through the bore, the fourth line having a first end extending above the object and a second end extending below the object;
a V-shaped fifth line having a first end coupled to the left side of the substantially rigid frame, a second end coupled to the right side of the substantially rigid frame, and at a cusp, the V-shaped fifth line being coupled to the cusp of the V-shaped third line;
the improvement which comprises a structurally modified second line formed into a resilient cable system designed to propagate a visual signal along its length so as to create a cue for the batter to initiate a swing wherein contact with the object of the object assembly occurs at the same time the visual signal reaches the object assembly and wherein the visual signal of the resilient cable consists of a series of spaced apart, Light Emitting Diodes (LED's) that are electrically connected for lighting in a manner that will create a cue for initiating a swing to contact the object of the object assembly.

### Claim 2 (depends on 1)

The improvement of claim 1 wherein the resilient cable system consists of:
a durable, substantially transparent and flexible outer sheath;
a main tension-bearing fiber having a proximate end coupled to the object assembly and a distal end coupled to a third substantially rigid member;
a substantially transparent inner sheath, designed to provide separation from the main tension-bearing fiber;
electric fibers contained in the inner sheath for connecting a plurality of equally spaced Light Emitting Diodes (LED's) along the length of the second line; and
a void filling material for reducing space between the LED's and the inner sheath and for absorbing shock and impact from hitting the object assembly.

### Claim 3 (depends on 2)

The improvement of claim 2, wherein the inner sheath extends beyond the distal end of the main tension-bearing fiber and operatively connects to a control unit.

### Claim 4 (depends on 3)

The improvement of claim 3, wherein the control unit contains a computing means that is programmable to control the pattern and timing of the LED lights and to create a speed adjustable, forward moving LED lighting sequence along the length of the second line in which the lighted LED progressively advances from the control unit to the object assembly.

### Claim 5 (depends on 4)

The improvement of claim 4, wherein the control unit contains means for a user to control the speed at which the lighted LED advances to the object assembly.

### Claim 6 (depends on 3)

The improvement of claim 3, wherein the control unit is operatively connected to means for detecting sound or motion so as to record a striking contact with the object.

### Claim 7 (depends on 6)

The improvement of claim 6, wherein the control unit includes computing means that is programmable to record a measurement of elapsed time from the lighting of the LED nearest the control unit to the detected contact with the object.

### Claim 8 (depends on 7)

The improvement of claim 7, wherein a desired performance goal is the swing event in which contact with the object is detected at about the same time the last LED is lighted at the proximate end of the second line.

### Claim 9 (depends on 7)

The improvement of claim 7, wherein the computing means is programmable to display a performance index of swing timing in milliseconds representing how early or late contact with the object was detected with reference to the lighting of the last LED.

### Claim 10 (depends on 7)

The improvement of claim 7, wherein the computing means is programmable to show a performance index representing a measured distance for how early or late contact with the object was detected with reference to the lighting of the last LED, through the lighting of an LED positioned at the measured distance from the last LED.

### Claim 11 (depends on 7)

The improvement of claim 7 wherein the control unit is connected to wireless means for transmitting performance index data to a receiving device for data analysis.

### Claim 12 (depends on 7)

The improvement of claim 7 wherein the computing means is programmable to continue the cycle of a forward moving LED lighting sequence wherein the lighted LED advances to the object and a swing performance index is calculated when contact with the object is detected.

### Claim 13 (depends on 6)

The improvement of claim 6, wherein the control unit further contains a display means for showing a calculated index of performance.

### Claim 14 (depends on 1)

The improvement of claim 1, wherein the equipment used to strike the object may be the same as those used in playing the physical game.

### Claim 15 (depends on 14)

The improvement of claim 14 wherein the equipment is a baseball bat.

### Claim 16 (depends on 1)

The improvement of claim 1 wherein the first line is formed of elastic fibers and the second line is formed of non-elastic fibers.

### Claim 17 (depends on 1)

The improvement of claim 1 wherein the resilient cable system is constructed to withstand the repeated flex and extension of the second line for allowing the object to be propelled to the frame after being hit and the corresponding tension created as the object rapidly rebounds to its original position through elastic properties of the first line.
