摘要： A variable stiffness striking implement, such as, for example, a ball bat typically used in baseball, softball, or rubber ball. The striking implement, preferably has a separate barrel and handle. A wedge and joint attached directly to the handle or indirectly to the handle using an interface portion engage the interior surface of the barrel. Most preferably, the wedge and joint are molded about the interface portion and a handle preform is then inserted into the intention of the interface portion and the handle is then molded. Wedge hardness is selectable and a stiffness member may also be employed. Stiffness member hardness may be selectable or may be adjustable by varied adjustment of a cap in relation to the barrel. Alternatively, the cap may not be adjustable in relation to the barrel so that a selected stiffness member hardness is fixed.

摘要： A method of forming a barrel portion including obtaining a mandrel shaped to define at least an inner surface of a barrel portion of the bat, wrapping a first plurality of layers of fiber composite material about the mandrel, placing a removable material over a first portion of the first plurality of layers, and wrapping a second plurality of layers of fiber composite material over the removable material and the portion of the first plurality of layers not covered by the removable material for form an assembly. The method further includes separating the mandrel from the assembly, inserting an expandable member within the assembly, inserting the assembly into a barrel-forming mold, and molding the assembly in a single molding cycle, curing the first and second layers with the removable material to form the barrel portion of the bat, and removing the removable material and the member from the barrel portion.

摘要： A golf club includes a face coupled to a body. A composite axis extends from a heel to a toe of the club and parallel to ground. The face is formed of a fiber composite material including at least first and second sets of ply arrangements. Each of the ply arrangements includes a pair of plies having first and second pluralities of fibers defining first and second angles with respect to the composite axis, respectively. The face has a ball contact surface, an rear surface, and a mid-zone positioned equidistant between the contact and rear surfaces. A majority of the first and second pluralities of fibers of the ply arrangements between the mid-zone and the contact surface are formed of glass fibers, and a majority of the first and second pluralities of ply arrangements between the mid-zone and the rear surface are formed of carbon fibers.

摘要： A ball bat may include a handle portion and a barrel portion extending away from the handle portion to an end cap. The barrel portion has an outer wall formed from aluminum and includes at least two and no greater than four inwardly projecting circumferential humps spaced by intervening circumferential valleys.

摘要： A ball bat, extending along a longitudinal axis. The bat includes a barrel portion, an end cap and a handle portion. The barrel portion is formed of a fiber composite material and includes a proximal region having a continuous single wall construction, a central region and a distal region. The central region includes at least first and second central region walls longitudinally extending from the proximal region, and a distal region includes first and second distal region walls longitudinally extending from the central region. The central region walls and the distal region walls form a first inner barrel wall and an outer barrel wall, respectively. The barrel walls are spaced apart by a first separation. The first separation is unfilled and longitudinally extends over the central region and the first distal region wall. The end cap and the handle portion are coupled to the distal and proximal region, respectively.
