Title:	Ball bat including integral barrel features for reducing BBCOR
Abstract:	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.

Patent Claims:	1. A ball bat, comprising: a barrel including a first barrel section and a second barrel section, wherein the first section and the second section are arranged longitudinally relative to each other, such that neither of the first and second barrel sections is contained within the other, to define a hollow interior region; wherein an end of the first barrel section comprises a first lip projecting inwardly into the interior region, and a first end of the second barrel section comprises a second lip projecting inwardly into the interior region, wherein the second lip is attached directly to the first lip at a sweet spot of the barrel; and a handle attached to or integral with a second end of the second barrel section. 2. The ball bat of claim 1 wherein the first lip is bonded or welded to the second lip. 3. The ball bat of claim 1 wherein a region above the attachment location of the first and second lips includes a filler material having an external surface that is continuous and flush with longitudinally neighboring external regions of the first and second barrel sections. 4. The ball bat of claim 3 wherein the filler material comprises a thermoplastic material. 5. The ball bat of claim 4 wherein the filler material comprises Surlyn.RTM. or thermoplastic polyurethane. 6. A ball bat, comprising: a barrel including a first barrel section and a second barrel section arranged longitudinally relative to each other, such that neither of the first and second barrel sections is contained within the other, to define a hollow interior region; a joint connecting the first barrel section to the second barrel section at a sweet spot of the barrel, wherein the joint includes a stiffening member projecting inwardly into the interior region; and a handle attached to or integral with the second barrel section. 7. The ball bat of claim 6 wherein the joint includes first and second mating surfaces to which the first and second barrel sections, respectively, are attached. 8. The ball bat of claim 7 wherein the first and second mating surfaces are welded or bonded to the first and second barrel sections, respectively. 9. The ball bat of claim 6 wherein external surfaces of the first and second barrel sections are continuous and flush with each other.
