초록 ▼

A ball bat includes one or more low-durability regions fortified by one or more reinforcing elements, such as a structural patch. If the reinforcing element is altered or removed, the durability of the ball bat is significantly reduced. For example, if the ball bat is subjected to internal shaving or external rolling in an attempt to increase the bat's performance, the reinforcing element would be removed or damaged such that the durability of the bat is reduced to the point that the ball bat's performance remains below a specified limit.

1. A ball bat, comprising: a handle;a barrel attached to or integral with the handle, the handle oriented in a longitudinal direction relative to the barrel, the barrel including: a first region having a first radially inner diameter;a second region having a second radially inner diameter that is substantially equal to the first radially inner diameter,a third region positioned longitudinally between the first and second regions, the third region having a third radially inner diameter that is greater than the first and second radially inner diameters;a structural patch attached to the first and second regions, the structural patch overlying the third region such that there is a void between the structural patch and the third region, wherein removal or detachment of the structural patch significantly reduces the durability of the barrel. 2. The ball bat of claim 1 wherein the structural patch comprises an aluminum alloy, annular ring with a thickness of approximately 0.040 inches. 3. The ball bat of claim 1 wherein the third region has a thickness that is approximately 75% or less of the thickness of the first and second regions. 4. The ball bat of claim 1 wherein the third region has a length in a longitudinal direction of the ball bat of approximately 0.5 inches. 5. The ball bat of claim 1 wherein the structural patch is bonded to the first region via a low-elongation adhesive. 6. The ball bat of claim 1 wherein the barrel comprises a material having a first stiffness, and wherein the structural patch comprises a material having a second stiffness that is greater than the first stiffness. 7. A ball bat, comprising: a handle;a barrel having a distal end and a proximal end that is attached to or integral with the handle, the barrel including: a first region having a first radially inner diameter;a second region adjacent to the first region having a second radially inner diameter that is greater than the first radially inner diameter;a structural patch attached to and protruding radially inwardly from the first region and overlying the second region, the structural patch not extending to the distal end of the barrel, wherein removal or detachment of the structural patch significantly reduces the durability of the barrel. 8. The ball bat of claim 7 wherein the structural patch comprises an aluminum alloy, annular ring with a thickness of approximately 0.040 inches. 9. The ball bat of claim 7 wherein the second region has a thickness that is approximately 75% or less of the thickness of the first region. 10. The ball bat of claim 7 wherein the second region has a length in a longitudinal direction of the ball bat of approximately 0.5 inches. 11. The ball bat of claim 7 wherein the barrel further comprises a third region having a third radially inner diameter that is substantially equal to the first radially inner diameter, wherein the second region is positioned between the first and third regions, and wherein the structural patch is attached to radially inner surfaces of the first and third regions. 12. The ball bat of claim 11 wherein the structural patch is bonded to the first and third regions via a low-elongation adhesive. 13. The ball bat of claim 7 wherein the barrel comprises a material having a first stiffness, and wherein the structural patch comprises a material having a second stiffness that is greater than the first stiffness. 14. The ball bat of claim 7 further comprising a void between the structural patch and the second region.
