A composite ball bat includes a bat body made of a multilayer fiber composite material and including a hollow barrel, a handle and a tapered section joining the barrel to the handle and having an outer diameter reducing gradually from the barrel toward the handle, and a tube member coaxially mounted in the hollow barrel of the bat body and having a hardness higher than that of the hollow barrel of the bat body. In this way, the composite ball bat of the present invention can use the tube member to improve the hitting effect while reducing the weight.

A composite ball bat includes a bat body made of a multilayer fiber composite material and including a hollow barrel, a handle and a tapered section joining the barrel to the handle, and a core material mounted in the hollow barrel of the bat body. The core material includes a rod member longitudinally set in parallel to the axial direction of the bat body, a plurality of rings attached onto the rod member and arranged along the axial direction of the rod member at equal intervals, and a plurality of elastic bands wrapped around the outer periphery of the rings within the inner peripheral surface of the hollow barrel in a one-to-one manner. In this way, the composite bat of the invention can use the core material to increase the structural strength, improve the hitting effect.

An end-cap assembly is configured to be attached to a distal end of a barrel of a ball bat. In some embodiments, the end-cap assembly includes a sprung-mass portion, a base portion, and one or more flexible members connecting the sprung-mass portion to the base portion. The sprung-mass portion is movable relative to the base portion along one or more directions, such as one or more directions transverse to the longitudinal axis of the ball bat. A ball bat may include a handle, a barrel attached to the handle, and an end-cap assembly attached to the barrel. The end-cap assembly may include a sprung-mass portion, a base portion, and one or more flexible members connecting the sprung-mass portion to the base portion to allow the sprung-mass portion to move relative to the distal end of the ball bat.

An end-cap assembly for a ball bat or other sporting-good implement includes one or more removable weights, so that the weight of the end cap—and of the ball bat—may be adjusted. The one or more weights may reside in a receiving space or recess in an end-cap cup of the end-cap assembly. A fastener removably attaches the one or more weights to the end-cap cup. In some embodiments, the fastener may include threads that engage threads in a bore in the end-cap cup.

A bat includes a ball hitting portion. The ball hitting portion includes a plurality of fiber-reinforced resin layers stacked in a radial direction relative to a center axis of the ball hitting portion. The plurality of fiber-reinforced resin layers include a first fiber-reinforced resin layer disposed at an outermost circumference in the radial direction among the plurality of fiber-reinforced resin layers. The first fiber-reinforced resin layer has a plurality of first fiber bundles and a plurality of second fiber bundles. The plurality of first fiber bundles are disposed side by side in a short side direction of each of the plurality of first fiber bundles. The plurality of second fiber bundles are disposed side by side in a short side direction of each of the plurality of second fiber bundles. The plurality of first fiber bundles and the plurality of second fiber bundles are woven across one another.

A ball bat includes at least one disc member in the bat barrel. The at least one disc member may include at least one solid disc member or at least one non-solid disc member with an opening, or both. The outer perimeters of the disc members may optionally be separated from the inner wall of the ball bat by a buffer layer, such as a layer of open-cell foam or adhesive. In some embodiments, the ball bat may further include at least one positioning member, such as an insulation foam member. The at least one positioning member may be located between two disc members, and multiple positioning members may optionally be arranged in alternating fashion with disc members within the bat. The at least one positioning member may be an insulation foam member having a hollow center portion.

A strung bat for use in playing cricket includes an elongate handle for a user to hold and a blade elongated in the direction of the handle. The blade includes a perimeter defining an internal space that is strung with an array of strings for hitting a ball. The perimeter frame has a leading edge and an opposing trailing edge, and the array of strings lies in a plane that may be substantially aligned with the leading edge of the frame or is closely adjacent to the leading edge of the frame. An apparatus for playing the game using the strung bat is also disclosed.
