Abstract
A baseball bat is shown having at the ball hitting portion a transverse cross section geometry of maximum frontal dimension and less mass than a full circular baseball bat, so as to improve the batting average, the speed, the distance and the directional accuracy of the batter. Moreover, the intermediate portion of the bat has optimum strength for its weight.
Claims2
A baseball bat comprising:
- a. a lower handle portion;
- b. an intermediate portion;
- and
- c. a ball-hitting portion;
- d. said ball-hitting portion having a transverse convex curvilinear cross section schematically divided into two ball-hitting half segments by a vertical cross plane that includes the longitudinal centerline of the bat, whereby one of the two ball-hitting half segments is less rounded and of a smaller sectional area than the other ball-hitting half segment while the two half segments join with each other generally on the vertical cross plane and are generally free of sharp corners, the said front ball-hitting half segment is formed substantially by a semi-ellipse, and the rear half segment is formed substantially by a semi-circle, where the major axis of the semi-ellipse substantially overlies both the diameter of the semi-circle and the said vertical cross plane.
