Abstract

A hollow non-wood baseball or softball bat wherein the impact portion of the bat contains an inner barrel that is positioned by means of a (i) foam insert, (ii) tube extending from the bat'"'"'s knob, or (iii) line attached to the bat'"'"'s knob and end cap and extending throughout the bat such that the inner barrel does not come into contact with the inside wall of the bat when the bat is at rest yet when swung the inner barrel is allowed to move so as to amplify the rebound effect given to the ball upon impact with the bat.

Claims

1. A bat, comprising:

a tubular frame having a circular cross-section, the tubular frame including a large diameter hitting portion, an intermediate tapering portion, and a small diameter handle portion;

a tubular insert positioned within the large diameter hitting portion, the insert having a circular cross-section, the insert having first and second ends, the insert being separated from the tubular frame by a void gap along the entire length of the insert, the gap being largely of constant width, the gap having such width so that the insert and the tubular frame will elastically deform in conjunction with each other when a baseball is struck;

a foam fitted within the insert, the foam protruding beyond the first and second ends of the insert and expanding beyond first and second ends of the insert such that the diameter of the expanded foam is greater than an outer diameter of the insert, allowing the insert to be suspended within the tubular frame, to move independently of the tubular frame, and to elastically deform in conjunction with the tubular frame when a baseball is struck to improve the rebound effect;

a knob covering an exposed end of the handle portion; and

a cap covering an exposed end of the hitting portion.

2. The bat according to claim 1 in which the foam is adhered to the tubular frame by an adhesive.
