摘要： Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

摘要： A composite ball bat comprising a handle, a tapered portion extending from an attachment end of the handle, and a barrel portion extending from the tapered portion to an end-cap end is provided. The barrel portion includes an inner surface and an outer surface. A foam core insert is preferably located within the barrel portion so that it is friction fit within the inner surface of the bat. The specific strength of the foam core insert may be 40 kNm/kg or more, and the specific modulus of the foam core insert may be at least 1,000 kNm/kg. The foam core insert is preferably less than 0.5 g/cc and preferably has a compressive strength greater than 16,500 kPa.

摘要： A ball bat configured for impacting a ball. The ball bat extends along a longitudinal axis and includes a unitary bat frame and a pivot joint. The unitary bat frame includes a handle portion and a barrel portion having a distal region. The pivot joint is coupled to the distal region of the barrel portion. The pivot joint movably supports the barrel portion relative to the longitudinal axis such that the distal region of the barrel portion may pivot towards and away from the longitudinal axis about the pivot joint.

摘要： 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.

摘要： A ball bat includes a barrel wall with a composite laminate structure that includes an outwardly facing skin, an inwardly facing skin, a stack of composite laminate plies positioned between the outwardly facing skin and the inwardly facing skin, and a discontinuity in the stack forming a gap along a longitudinal axis of the bat. A rigid or semi-rigid appliance may be positioned in the gap. The appliance may be a ring element, which may have a cross-section that traverses the composite laminate plies in the stack in a direction that is perpendicular or oblique to the longitudinal axis of the bat. The cross-section of the ring element may be triangular. A second ring element may be positioned in the barrel wall. The second ring element may be connected to the other ring element with an adhesive bond or a connecting element.

摘要： 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.

摘要： A barrel of a ball bat may include a composite laminate with a plurality of composite plies. One or more translaminar elements may pass through the composite plies and around a circumference of the barrel to reduce relative movement between the plies. The translaminar elements may include a first line of stitching, which may include aramid fiber. In some embodiments, the first line of stitching forms two or more coils around the barrel. Lines of stitching may be positioned on opposing sides of a center of percussion of the ball bat. In some embodiments, the translaminar elements may include a line of staples distributed around the circumference of the barrel. A method of making a ball bat may include arranging plies of composite material to form a cylinder, passing a first translaminar element through the plies, and curing the assembly of plies to form a barrel of the ball bat.

摘要： A system for determining information associated a bat includes a bat having a handle, a barrel extending from the handle, and a cap connected to the barrel opposite the handle. The cap is connected to a first portion of a chip, and a second portion of the chip is connected to a portion of the bat other than the cap. A user device communicates with the chip on a network to receive the information associated with the bat or to receive second information used to obtain the information associated with the bat. The information associated with the bat may be whether the cap has been removed, which may identify whether the bat has been modified.
