Abstract

A training bat has a handle portion and a barrel portion. The barrel portion has a hollow cavity formed within and has an opening for accessing the cavity. A plurality of nestable weights can be disposed in the barrel cavity in combination. A means for closing the barrel opening is used so that the weights may be fixedly secured inside the barrel cavity.

Claims

1. A training bat comprising:

a baseball bat having an integral handle and barrel portion, said barrel having a hollow cavity formed therein and an opening for accessing said cavity;

a removable end cap for lockably closing said opening, the end cap cooperating with the hollow cavity to define the length of the barrel cavity when the end cap is secured to the bat;

a first weight having a length substantially equal to the length of said barrel cavity with a chamber therein, said first weight shaped to removably nest within said barrel cavity;

a second weight having a length substantially equal to the length of the chamber of said first weight shaped to removably nest within the chamber of said first weight; and

a means for measuring the speed of the bat when swung.

2. The training bat of claim 1 wherein said first weight is substantially frustoconical in shape.

3. The training bat of claim 2 wherein the second weight is substantially cylindrical in shape.

4. A training bat comprising:

a baseball bat having a handle and barrel portion, said barrel having a hollow cavity of fixed length formed therein and an opening for accessing said cavity; and

a plurality of removable nestable weights which can be selectively disposed in said barrel cavity in combination, one of said weights having a chamber therein, and another of said weights shaped to nest within the chamber, wherein at least one of said weights has a length equal to the length of said barrel cavity.

5. A training bat comprising:

a baseball bat having an integral handle and barrel portion, said barrel having a hollow cavity formed therein and an opening for accessing said cavity;

a removable end cap for lockably closing said opening, the end cap cooperating with said cavity to define the length of the barrel cavity when the end cap is secured to the bat;

a frustoconical first weight of a length substantially equal to the length of the barrel cavity having a cylindrical chamber therein, said first weight shaped to removably nest within said barrel cavity;

a cylindrical second weight of a length substantially equal to the length of the first weight chamber shaped to removably nest within the cylindrical chamber of said first weight; and

a means for measuring the speed of the bat when swung.
