A bat has an elongate tubular striking member of a first material, and an elongate handle member of a second material. The handle may be of composite material laid up in selected layers and orientation to produce selected weight distribution, strength, and stiffness and improved batting capabilities. The striking member and handle member may have juncture sections which are substantially rigidly interconnected through mating configurations.

This invention relates to a ball bat, and more particularly to a ball bat with a striking barrel member made to provide desired striking capabilities, and a handle member made to provide desired swinging capabilities, and a method for manufacturing such which produces a rigid interconnection between the barrel and handle members.
Tubular metallic baseball bats are well known in the art. A familiar example is a tubular aluminum bat. Such bats have the advantage of a generally good impact response, meaning that the bat effectively transfers power to a batted ball. This effective power transfer results in ball players achieving good distances with batted balls. An additional advantage is improved durability over crack-prone wooden bats.
Even though presently known bats perform well, there is a continuing quest for bats with better hitting capabilities. Accordingly, one important need is to optimize the impact response of a bat. Further, it is important to provide a bat with proper weighting so that its swing weight is apportioned to provide an appropriate center of gravity and good swing speed of impact components during use.
FIG. 1 is a sectional view through the longitudinal center of a bat in accordance with one embodiment of the invention.
FIG. 2 is a magnified sectional view of a juncture section of the bat of FIG. 1.
FIG. 3 is a cross sectional view taken generally along the line 3-3 in FIG. 2.
Referring to FIG. 1, an elongate tubular ball bat 10 having a longitudinal axis, or centerline, 20 comprises an elongate tubular striking member 12. The striking member has a proximal, or inner, end 12a and a distal, or outer, end 12b. A striking region 14 is disposed intermediate ends 12a, 12b. A frusto-conical juncture section 16 of the striking member adjacent end 12a converges toward centerline 20 on progressing toward end 12a.
In the embodiment illustrated in FIGS. 1 and 2 striking region 14 has a substantially cylindrical inner cavity, with an inner diameter D1. A cylindrical tubular insert 22 is received in the striking region cavity to form a multiple-wall bat. The insert has proximal, or inner, and distal, or outer, ends 22a, 22b, respectively. End 22a is disposed adjacent juncture section 16. The bat also could be made as a single-wall bat without insert 22.
Juncture section 16 has a major diameter equal to D1 and a minor diameter noted D2 at its end 12a.
