Abstract
Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.
Claims7
A baseball training bat comprising:
- an elongated shaft having a portion of its interior being removed, defining an internal cavity;
- and
- at least one added weight made from a polymer material that is formed in only the portion of the internal cavity to provide the added weight in only a specific area of the elongated shaft,
- wherein the portion extends a length that is less than the entire length of the elongated shaft;
- wherein the added weight is configured to be cured to a sidewall of the internal cavity,
- wherein the weight of the baseball training bat with the cured polymer material is greater than the weight of the baseball training bat that does not have its interior removed,
- wherein the added weight is distributed evenly along the portion of the internal cavity over which the added weight is distributed.
