Abstract

A training and coordination device including a projectile member such as a ball or sack secured to an elastic string is described. The first end of the elastic string is attached to a location and the second end is connected to the projectile member. At least an end portion of the elastic string secure to the projectile member comprises multiple strands of an odd number. The multiple strands of the elastic string in conjunction with the elasticity of the string generate a random motion of the sack when the sack moves relative to the string.

Claims

1. A training and coordination device for improving coordination of a user, comprising:

a string formed of a first section and a second section having first and second ends respectively,

the first end of said first section associated with a first end of said string, and the second end of said first section terminating at a predetermined point spaced from the second end of said second section, said first section being formed of a single, uninterrupted strand portion having elasticity,

the second end of said second section associated with a second end of said string, said second section including a multi-strand portion, said multi-strand portion including at least three separate strands and having a length of about one to two feet, said first end of said multi-strand portion attaching to said second end of said single, uninterrupted strand portion;

a projectile member associated with the second end of said string;

wherein said elasticity of said single strand portion and said at least three separate strands of said multi-strand portion produce random motion in said projectile member when the first end of the string is attached to a fixed location so that the projectile member is freely suspended from the fixed location and a user makes contact with the projectile member.

2. The training and coordination device of claim 1, wherein the string is made of polyester or rubber.

3. The training and coordination device of claim 1, further comprising a first loop attached to the projectile member;

and

wherein the string includes a second loop secured to the at least three separate strands and the second loop is attached to the first loop.

4. The training and coordination device of claim 1, wherein the single, uninterrupted strand portion and the multi-strand portion are formed from a single length of string, the multi-strand portion comprising adjacent loops in the single length of string, and extending at least from a junction with the single, uninterrupted strand portion to the second end of the second section, from said second end back to said junction, and from said junction back to said second end.

5. The training and coordination device of claim 1, wherein the projectile member comprises a sack containing a plurality of separate pellets, the sack being of a non-rigid material selected from the group consisting of woven material, synthetic fabric material, plastic, and leather.

6. The training and coordination device of claim 5, wherein the pellets are selected from the group consisting of seeds, beans, plastic pellets, and wooden pellets.

7. The device of claim 1, further comprising:

an attachment loop attached to the projectile member, for engaging the elastic string;

a location loop attached to the first end of the string, for engaging the fixed location; and

a string loop attached to the second end of the second portion of the string, for engaging the attachment loop; and

wherein the second end of the second portion of the string is attached to the projectile member indirectly via the string loop and the attachment loop.

8. The device of claim 1, wherein the multiple strand portion has an odd number of strands of the elastic string.

9. The device of claim 1, wherein the string has a length between the first end and the second end within the range of 4 to 15 feet.

10. A martial arts device for training and coordination of a user, the martial arts device comprising:

a sack including an outer portion containing a stuffing; and

a string member including a first end and a second end, the first end configured to attach to a fixed location, the second end attached to the sack, the string member having an elasticity that provides recoil of the sack when struck or thrown, the string member further including a single strand portion extending from the first end to a junction, and a multiple strand portion extending from the junction to the second end, the multiple strand portion configured to produce a random motion return path of the sack after being struck or thrown.

11. The martial arts device of claim 10, further comprising:

an attachment loop attached to the sack, for engaging the string member;

a location loop attached to the first end of the string member, for engaging the fixed location; and

a string loop attached to the second end of the string member, for engaging the attachment loop; and

wherein the second end of the string member is attached to the sack indirectly via the string loop and the attachment loop.

12. The martial arts device of claim 10, wherein the string member is made up of a single length of string and the multiple strand portion is made up of at least three sections of the single length of string bent over and adjacent each other, and knotted together at the junction.

13. The martial arts device of claim 10, wherein the multiple strand portion has an odd number of strands equal to or greater than three.

14. The martial arts device of claim 11, wherein the string member is made of polyester or rubber.

15. The martial arts device of claim 10, wherein the string member has a variable length between the first end and the second end within the range of 4 to 15 feet.

16. The martial arts device of claim 10, wherein the stuffing includes at least one of seeds, beans, plastic pellets and wooden pellets.

17. A device for training and coordination of a user, the device comprising:

a ball; and

an elastic string including a first end and a second end, the first end configured to attach to a fixed location, the second end attached to the ball, the elastic string having an elasticity that adds to a movement of the ball when the first end is attach to the fixed location and the ball is struck or thrown, the elastic string further including a single strand portion extending from the first end to a junction, and a multiple strand portion extending from the junction to the second end, the multiple strand section configured to produce a random motion return path of the movement of the ball after being struck or thrown.

18. The device of claim 17, wherein the elastic string is made up of a single length of string, the multiple strand portion being made up of at least three sections of the single length of string bent over and adjacent each other, and knotted together at the junction.
