## Background
This application is a continuation-in-part of application Ser. No. 10/189,904 filed Jul. 2, 2002 now U.S. Pat. No. 6,682,447.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to baseball bat training devices and more specifically it relates to a training bat system for increasing the batting skills of a baseball player.
2. Description of the Related Art
Batter training devices have been in use for years. A commonly utilized batter training device is comprised of a weight having a ring structure that surrounds the barrel of a baseball bat often times referred to as a “doughnut.” The weight placed upon a conventional baseball bat increases the overall weight of the baseball bat and the player then swings the baseball bat repeatedly with the weight placed upon thereof.
While weights for baseball bats assist the player in developing increased strength, they do not assist the player in developing increased ball engagement accuracy. Conventional baseball bat devices do not significantly increase the mental and physical focus required to engage a baseball with the bat.
Examples of patented devices which may be related to the present invention include U.S. Pat. No. 3,116,926 to Owen et al.; U.S. Pat. No. 6,050,908 to Muhlhausen; U.S. Pat. No. 4,682,773 to Pomilia; U.S. Pat. No. 339,621 to Briden; U.S. Pat. No. 6,280,353 to Brundage; U.S. Pat. No. 5,741,193 to Nolan; and U.S. Pat. No. 5,456,461 to Sulllivan.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for increasing the batting skills of a baseball player. Conventional baseball bat training devices do not significantly assist with developing mental and physical focus for engaging a baseball.
In these respects, the training bat system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of increasing the batting skills of a baseball player.

DETAILED DESCRIPTION OF THE INVENTION
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 5 illustrate a training bat system 10, which comprises a tubular member 20 having a center bore 27, a plurality of weight members 60 removably positioned within the center bore 27, an inner cap 40 secured to an inner end 23 of the tubular member 20, and an outer cap 30 secured to the outer end of the tubular member 20. A compression spring 50 is preferably positioned between the weight members 60 and the inner cap 40 for maintaining the weight members 60 non-movably adjacent one another. The tubular member 20 has an outer diameter similar to a handle gripping of a baseball bat.
As shown in FIGS. 1 through 5 of the drawings, the tubular member 20 is an elongate structure having a length similar to the length of a conventional bat. The tubular member 20 has an open distal end 21 and an open inner end 23 which are both interiorly threaded as best illustrated in FIG. 5 of the drawings. It can be appreciated that either the distal end 21 or the inner end 23 may be a closed structure as only one end is required to input the weight members 60 within the tubular member 20.
The tubular member 20 is comprised of a relatively rigid material such as but not limited to metal, plastic, polymer, or similar material. A suitable polymer material for the tubular member 20 is manufactured by DUPONT under the trademark KEVLAR. The tubular member 20 in the preferred embodiment is made of aluminum.
The tubular member 20 has a center bore 27 that extends from the inner end 23 to the distal end 21 thereof as best shown in FIG. 5 of the drawings. The bore 27 may stop before or extend through the distal end 21 of the tubular member 20. The bore 27 is preferably comprised of a consistent diameter, however the bore 27 may be comprised of varying diameters to accommodate similar sized weight members 60. The bore 27 may have various cross sectional shapes such as but not limited to circular, square and the like.
The exterior portion of the tubular member 20 has approximately the same outer diameter as a conventional bat for the user to grasp. The tubular member is approximately the same diameter along its entire length. Thus, the tubular member 20 diameter at the end for hitting the ball is considerably smaller than a conventional bat thereby making it relatively difficult for a user to engage a ball. The tubular member's 20 length is approximately the same as a regular bat.
The distal end 21 of the tubular member 20 is interior threaded within the bore 27 as best shown in FIG. 5 of the drawings. A recessed cavity 25 is preferably positioned within the distal end 21 of the tubular member 20 for allowing the outer cap 30 to be threadably inserted within relatively flush with the distal end 21 as shown in FIGS. 4 and 5 of the drawings. The outer cap 30 may have one or more slots for allowing a tool to engage for removal and insertion thereof within the tubular member 20.
As shown in FIGS. 1 through 4 of the drawings, an inner cap 40 having a threaded extended portion 42 is threadably engageable within the inner end 23 of the tubular member 20. The inner cap 40 preferably have a flanged structure that is similar to an inner portion of a conventional baseball bat. A compression spring 50 may be inserted after the inner cap 40 for maintaining the weight members 60 in a compressed structure as shown in FIG. 4 of the drawings.
As shown in FIGS. 3 and 4 of the drawings, a plurality of weight members 60 are provided that are removably inserted into the bore 27 of the tubular member 20 from either/both the inner end 23 and the distal end 21. The weight members 60 have an outer shape similar to the shape of the bore 27. The weight members 60 are formed to slidably fit within the bore 27 with reduced movement within the bore 27. The weight members 60 are preferably comprised of various lengths and weights to allow for the user to balance the tubular member 20 to simulate the weight and balance of their regular bat he would use in a game or a heavier bat. The weight members 60 may be comprised of various materials such as but not limited to metal, plastic, polymers and other well-known materials. The lengths of the weight members 60 may range from 0.5 to 8 inches.
In use, the user inserts a plurality of weight members 60 into the bore 27 of the tubular member 20 based upon an estimated overall weight of the normal bat he would use in a game. The user is able to insert heavier/denser weight members 60 comprised of metal within locations along the bore 27 in order to increase the weight of a specific section. The user is able to insert lighter weight members 60 comprised of plastic or other materials within locations along the bore 27 in order to decrease the weight of a specific section. The user then secures the inner cap 40 and the outer cap 30 with the compression spring 50 positioned between the inner cap 40 and the weight members 60 thereby maintaining the weight members 60 in a compressed state within the tubular member 20.
The user uses this training bat 10 to hit with in batting practice. Since the end of the tubular member 20 used to engage the ball when batting is much smaller than a conventional bat the user must focus both physically and mentally on making contact with the ball than when using a conventional bat. A smaller, lighter ball can also be used to further increase the mental and physical concentration. Thus, the bat training system 10 will improve the user hitting ability by causing him to concentrate and focus more on hitting the ball. It will also improve his hand/eye coordination.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed to be within the expertise of those skilled in the art, and all equivalent structural variations and relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
