초록 ▼

A ball bat includes a barrel having one or more integral features for selectively stiffening regions of the barrel. The barrel may include an indented region forming a rib projecting inwardly into the barrel. Alternatively, one or more inwardly projecting lips may be formed on adjoining barrel sections that are bonded, welded, or otherwise attached to each other, such that an integral, internal rib is formed in the barrel. The internal rib stiffens the barrel, thus reducing the barrel's BBCOR. One or more integral ribs may be provided at any desired barrel locations for selectively limiting the barrel's performance without appreciably increasing the moment of inertia of the ball bat. In another embodiment, a joint, to which two barrel sections are bonded, welded, or otherwise attached, includes an inwardly projecting member that stiffens the barrel, thus reducing the barrel's BBCOR.

1. A ball bat, comprising: a barrel including a shell;a handle attached to or integral with the barrel; andmeans for limiting the ball-bat coefficient of restitution of at least one region of the barrel relative to longitudinally neighboring regions of the ball bat, the means comprising: an indented region of the shell that forms a channel around the circumference of the barrel; anda filler material in the indented region having an external surface that is continuous and flush with longitudinally neighboring external regions of the barrel. 2. The ball bat of claim 1 wherein the filler material comprises a thermoplastic material. 3. The ball bat of claim 1 wherein the barrel includes a sweet spot, and wherein the indented region is located at the sweet spot. 4. The ball bat of claim 3 wherein the indented region has a width of approximately 0.625 inches, and a depth of approximately 0.25 inches. 5. The ball bat of claim 4 wherein the filler material has a coefficient of restitution of less than 0.80, resulting in a ball-bat coefficient of restitution of less than 0.50 at the sweet spot of the barrel. 6. A ball bat, comprising: a barrel including a first barrel section and a second barrel section;wherein an end of the first barrel section comprises an inwardly projecting, curved first portion;wherein an end of the second barrel section comprises an inwardly projecting, curved second portion that is attached to the curved first portion;a filler material on a radially outer surface of the curved first portion and the curved second portion, the filler material having an external surface that is continuous and flush with longitudinally neighboring external regions of the first and second barrel sections; anda handle attached to or integral with the second barrel section. 7. The ball bat of claim 6 wherein the curved first portion is bonded or welded to the curved second portion. 8. The ball bat of claim 6 wherein the filler material comprises a thermoplastic material. 9. The ball bat of claim 6 wherein the barrel includes a sweet spot, and wherein the curved first portion and the curved second portion are attached at the sweet spot. 10. A ball bat, comprising: a barrel including a first barrel section connected to a second barrel section via a joint, wherein external surfaces of the first and second barrel sections are continuous and flush with each other;a handle attached to or integral with the barrel; andmeans for limiting the ball-bat coefficient of restitution of at least one region of the barrel, the means comprising an inwardly projecting portion of the joint located substantially at the sweet spot of the barrel. 11. The ball bat of claim 10 wherein the joint includes first and second mating surfaces to which the first and second barrel sections, respectively, are attached. 12. The ball bat of claim 11 wherein the first and second mating surfaces are welded or bonded to the first and second barrel sections, respectively. 13. The ball bat of claim 10 wherein the barrel includes a sweet spot, and wherein the joint is located at the sweet spot.
