摘要:
A ball bat extending about a longitudinal axis. A bat includes a tubular bat frame. The bat frame includes first and second frame pieces. The first frame piece has a gripping portion integrally formed to a transition portion, and the transition portion has a distal end region. The second frame piece has a proximal end region. The distal end region of the first piece is coupled to the proximal end region of the second piece. One of the distal and proximal end regions overlaps the other of the distal and proximal end regions. The bat has a center of percussion, and the mid-length of the overlap of the distal and proximal end regions is positioned within plus or minus three inches of the center of percussion of the bat.
摘要:
A bat has an elongate tubular striking member of a first material, and an elongate handle member of a second material. The handle may be of composite material laid up in selected layers and orientation to produce selected weight distribution, strength, and stiffness and improved batting capabilities. The striking member and handle member may have juncture sections which are substantially rigidly interconnected through mating configurations.
摘要:
A ball bat extending about a longitudinal axis. The bat includes a bat frame, a knob and an annular member. The bat frame has a handle portion and a tubular barrel portion. The bat has a proximal end, a distal end, a center of percussion and a length of at least thirty inches. The barrel portion has an inner surface. The knob is coupled to the handle portion. The annular member is coupled to the inner surface. The annular member has a center of mass and is positioned within the barrel portion such that the center of mass is longitudinally spaced apart from the center of percussion by a first distance of at least 0.25 inches. The annular member increases the moment of inertia of the bat measured about an axis positioned six inches from the base of the knob of the bat by no more than twenty percent.

摘要:
A ball bat extending about a longitudinal axis. The bat includes a handle and a barrel portion. The barrel portion has an outer surface and includes a proximal member and a distal member. The proximal member has first and second end regions and the distal member has third and fourth end regions. The first end region is coupled to the handle portion, the second end region of the proximal member is coupled to the third end region of the distal member, and the fourth end region of the distal member is coupled to an end cap. At least a portion of each of the proximal and distal members defines the outer surface of the barrel portion. One of the second and third end regions overlaps the other of the second and third end regions.

摘要:
A ball bat includes a substantially tubular frame having a handle portion and a primary hitting portion. The handle portion is formed of a non-steel material. The hitting portion is formed separately from, and coupled to, the handle portion. The hitting portion is formed of a steel and has an inner surface and an outer surface. At least a portion of hitting portion is carburized forming a carburized layer.
摘要:
A bat includes a substantially tubular frame, a substantially tubular body and at least one sheet. The frame extends along a longitudinal axis. The frame has a handle portion and a primary hitting portion. The body is coaxially aligned with the hitting portion of the frame. The sheet has a proximal edge, a distal edge, and first and second side edges. The sheet is coupled to at least a portion of one of the hitting portion of the frame and the body such that the first and second edges each extend from the proximal edge to the distal edge along a path that is substantially non-parallel with the longitudinal axis.
