Provided is a swing speed analyzer for mounting on a swinging implement and comprising a first accelerometer, a processor and a shock attenuator. The processor uses an output from the first accelerometer to compute a swing speed of the swinging implement. The shock attenuator is comprised of a material that is sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz. The material is preferably sized and dimensioned to dampen the impact shock wave from more than 1000 g to less than 500 g. Suitable attenuators can include viscoelastomeric materials such as foam. The swing speed analyzer can advantageously include any of a releasable attachment mechanism, a liquid crystal or other visual display, a second accelerometer, and a strain gauge. The analyzer can advantageously be attached to a golf club, a tennis racket, a baseball bat, or a hockey stick.

A warm-up bat includes a tubular shell with a handle section, a barrel section, and a tapered section connecting the handle section with the barrel section. The handle is attached at an end of the handle section of the bat. An end cap is attached at an end of the barrel section of the bat. A sliding weight mechanism is entirely contained within the barrel section of the bat, and is positionally supported on a shaft.

A hollow non-wood baseball or softball bat wherein the impact portion of the bat contains an inner barrel that is positioned by means of a (i) foam insert, (ii) tube extending from the bat's knob, or (iii) line attached to the bat's knob and end cap and extending throughout the bat such that the inner barrel does not come into contact with the inside wall of the bat when the bat is at rest yet when swung the inner barrel is allowed to move so as to amplify the rebound effect given to the ball upon impact with the bat.

A multi-walled, tubular baseball bat has a barrel portion with a mid-section wherein the radial stiffness of the overall barrel wall varies along the barrel length to provide an enlarged sweetspot, improved soft feel and performance, plus unique sounds upon impact. The bat has a frame with a barrel portion of consistent diameter. A secondary member, or members, of tubular form extend internally along the barrel. The secondary member provides the required radial stiffness variation by: 1) variations in the thickness of the wall of the secondary member or by, 2) secondary members with unique geometric external surface profiles or by, 3) the presence of functional air cavities, with or without closed ends, between the main bat frame and the secondary member or members or by, 4) the presence of numerous annular secondary members located side by side less than one-half the length of the barrel portion.

Assembling a multi-component baseball bat includes disposing a rigid sleeve coaxially over a portion of an elongate composite handle. The rigid sleeve encircles a second end of the handle and extends toward a first end of the handle. A ring is positioned near a second end of a bat barrel. A first end of the bat barrel is inserted into the second end of the handle; the first end of the bat barrel being secured within the second end of the handle. An illustrative bat includes an elongate composite handle and an elongate barrel, each having opposite first and second ends. The first end of the barrel is disposed within the second end of handle. A mechanism secures the first end of the barrel within the second end of the handle. A rigid sleeve encircles the second end of the handle, extending towards the first end thereof.

A vibration damping baseball bat includes a barrel portion and a handle portion. The barrel portion and the handle portion are interconnected in an aligned and spaced-apart relation. The mechanism by which the barrel and handle portions are interconnected dampens vibrations created when a ball contacts the bat and provides limited pivotal movement of the barrel portion relative to the handle portion.

A process for assembling a multi-component baseball bat includes providing a bat barrel having an end with a plurality of slots and selecting a bat handle. A section of the handle is enveloped by the end of the barrel. The barrel and handle are interconnected in coaxial engagement to define an intermediate tapered section which returns energy and power to the barrel that emanates from the barrel due to an impact of a ball on the barrel. An example of a multi-component baseball bat formed by the process includes a bat barrel having a plurality of slots; a bat handle; and a connector attached to an end of the handle. The connector engages the slots of the barrel and is coaxially disposed between the barrel and the handle for interconnecting the barrel and handle in an aligned relation, to return energy and power to the barrel.

A swing implement, such as a baseball bat (9), adapted for gripping by the hands of a user having a support surface (10) between the knob (20) and the handle (30) of the swinging implement. The support surface provides a gradual transition between the knob and the handle. The support surface supports the hand of the user while gripping the swinging implement. Another swinging implement (10) comprises a support surface extending at a shallow angle from the handle between the handle and the end surface of the knob for supporting the hand of the user while gripping the swinging implement. A support sleeve (6c) adapted to cooperate with a handle and knob of a conventional baseball bat including a support surface for providing added support for the hands of a user gripping the bat.
