Abstract

The swing training aid includes an arm band and an adjustable cord attached to the racket and the arm band through an adjustable hook. The arm band is adjustably and detachably secured around an arm of a player. A hook strap is attached on the outside of the arm band and defines an opening for receiving the hook. The elastic cord has one end having a loop whose diameter is sufficiently large to receive a handle of the sport swing instrument. The adjustable hook has a base and a hook portion extending from the base and terminating at a hook end. The hook portion is designed to be coupled to the hook strap and the base of the adjustable hook is designed to receive the end of the elastic cord and adjustably lock the cord once the cord length has been adjusted for the player.

Claims

1. A sport swing instrument training device comprising:

an arm band adapted to be adjustably and detachably secured around an arm of a player;

a hook receiver attached on the outside of the arm band and defining an opening for receiving a hook;

an elastic cord having a first end and a second end having a loop whose diameter is sufficiently large to receive a handle of the sport swing instrument;

an adjustable hook having a base and a hook portion extending from the base and terminating at a hook end, the hook portion adapted to be coupled to the hook receiver, the base of the adjustable hook adapted to receive the first end of the elastic cord and adjustably lock the cord;

wherein the arm band has an elastic inner band having an inner surface and an outer surface and the distal portion of the inner surface of the inner band is adapted to be fastened to the outer surface of the inner band.

2. The sport swing instrument training device of claim 1, wherein the elastic cord has a 50% stretch with 5 pounds or less of force.

3. The sport swing instrument training device of claim 1, wherein the elastic cord has a 50% stretch with 2 to 4 pounds of force.

4. The sport swing instrument training device of claim 1, wherein the inner diameter of the loop in unstretched form is between 5 inches and 11 inches, inclusive.

5. The sport swing instrument training device of claim 1, wherein the elastic cord has a clamped ring to define the loop and a heat shrunk tube surrounding the clamped ring.

6. The sport swing instrument training device of claim 1, wherein the arm band has a non-elastic outer band extending from the inner band.

7. The sport swing instrument training device of claim 6, wherein the hook receiver includes a hook strap positioned on the outer surface of the outer band to define hook receiving opening therebetween.

8. The sport swing instrument training device of claim 7, wherein the arm band includes a slit attached to the outer surface of the outer band through which a distal end of the outer band is inserted and looped back, and the distal portion of the outer surface of the outer band is adapted to be fastened to the outer surface of the outer band.

9. The sport swing instrument training device of claim 8, wherein the hook strap is attached to the outer surface of the outer band and positioned distally from the slit.

10. The racket swing training device of claim 1, wherein:

the base has a stationary flexible tongue whose free end is spaced from the hook end to define a hook entrance through which the hook receiver enters,

the base includes an entrance opening, an exit opening and a tapered cord locking slot positioned therebetween, wherein the first end of the cord is adapted to enter the entrance opening and exit through the exit opening while the tapered cord locking slot engages the cord to adjustably lock the cord.

11. The racket swing training device of claim 10, wherein the entrance opening is a closed opening and the exit opening is a partially open exit opening.

12. The racket swing training device swing training device of claim 1 wherein the base includes:

a fixed portion fixedly attached to the hook portion; and

a rotatable portion rotatably coupled to the fixed portion and adapted to adjustably lock the cord.

13. A racket swing training device comprising:

an arm band adapted to be adjustably and detachably secured around an arm of a racket sport player, wherein the arm band has an elastic inner band having an inner surface and an outer surface and the distal portion of the inner surface of the inner band is adapted to be fastened to the outer surface of the inner band;

a hook strap attached on the outside of the arm band and defining an opening therebetween for receiving a hook;

an elastic cord having a first end and a second end having a loop sufficiently large to receive a racket handle, the loop adapted to be securely attached to a throat of the racket;

an adjustable hook having a base and a hook portion extending from the base and terminating at a hook end,

the base having a flexible tongue whose free end is spaced from the hook end to define a hook entrance through which the hook strap enters,

the base including an entrance opening, an exit opening and a tapered cord locking slot, wherein the first end of the cord is adapted to enter the entrance opening and exit through the exit opening while the tapered cord locking slot engages the cord to adjustably lock the cord in use.

14. The sport swing instrument training device of claim 13, wherein the elastic cord has a 50% stretch with 5 pounds or less of force.

15. A method of using a racket swing training device comprising:

adjustably and detachably securing an arm band around an arm of a racket sport player, wherein the arm band has an elastic inner band having an inner surface and an outer surface and securing the arm band around the arm includes fastening the distal portion of the inner surface of the inner band to the outer surface of the inner band;

slidably inserting a loop defining a second end of an elastic cord over a handle of the racket;

inserting the elastic cord through an open throat of the racket;

pulling on a first end of the elastic cord to securely fasten the loop to the throat of the racket;

inserting a hook portion of an adjustable hook through an opening defined by a hook strap attached on the outside of the arm band, the adjustable hook securely and adjustably locking the elastic cord to place a wrist of the player in an extended position.

16. The method of claim 15, wherein the adjustable hook has a base including an entrance opening, an exit opening and a tapered cord locking slot, the method further comprising inserting the first end of the elastic cord through the entrance opening and then through an exit opening such that the tapered cord locking slot adjustably locks the cord.
