20140274497 | SPORTING-GOOD IMPLEMENT WITH ROTATABLE HANDLE - A sporting-good implement, such as a ball bat or a lacrosse stick, includes a first handle section rotatably connected to a second handle section. The second handle section may be attached to or integral with a tapered region or barrel region of a ball bat, or with a shaft section or head of a lacrosse stick, or with another sporting-good feature. This rotatable engagement allows the relative position of the user's hands to change during the course of a swing, shot, or pass, ideally placing the user's hands in a position to generate improved power or control. | 09-18-2014 |
20140349790 | BASEBALL BAT - Baseball bats described herein may have handle, throat and/or barrel portions that include non-circular cross-sections. | 11-27-2014 |
20150065278 | MULTI-COMPONENT BAT AND ASSEMBLY PROCESS - A baseball or softball bat includes an elongated handle having an interconnection member at one end. The handle is inserted through a bat barrel to position the interconnection member within the bat barrel, with the remainder of the handle extending outwardly from the bat barrel. The bat barrel and the interconnection member are attached to one another. The interconnection member may be turned relative to the bat barrel to engage threads of the interconnecting member and a connection region of the bat barrel to attach the interconnecting member and handle to the bat barrel. A knob and a grip are associated with the handle and an end cap attached to an open end of the bat barrel. | 03-05-2015 |
20160158617 | BAT WITH MULTIPLE HITTING PROFILES - A ball bat includes one or more stiffeners configured to provide an attenuating surface that limits the bat barrel's elastic deformation as the barrel deflects radially inwardly as a result of a particularly violent bat to ball collision. The stiffener is spaced apart from the inner surface of the barrel a predetermined distance to form a gap, wherein the gap extends only partially around the inner circumference of the barrel. The presence of the gap extending only partially around the barrel circumference provides multiple hitting profiles around the bat's circumference, with the best performance occurring adjacent the gap, and a reduced performance at all other locations around the bat's circumference. | 06-09-2016 |
