A knob sleeve assembly for a ball bat extending along a longitudinal axis and having a tubular handle portion and a knob attached the handle portion. The knob sleeve assembly includes a plurality of annular bodies formed of a resilient material. Each of the bodies defines a central opening for receiving the handle portion of the bat. Each of the bodies has an annular body height within the range of 0.25 to 1.0 inch, and a maximum annular body outer diameter within the range of 1 to 3 inches. The plurality of annular bodies varies from one another according to at least one annular body characteristic. The knob sleeve characteristic is selected from the group consisting of annular body height, maximum annular body outer diameter, weight, color, material durometer value, annular body draft angle and combinations thereof.

A golf club shaft includes: a butt end; a tip end, where the golf club shaft is tapered between the butt end and the tip end; coils of fiber wound helically relative to an axis of the golf club shaft; and one or more layers of composite material wrapped around the coils of fiber and disposed radially outwardly of the coils of fiber.

A bat having a handle inner shaft and a grip sleeve surrounding and radially spaced from the handle inner shaft.

A split grip baseball bat for use in training batters to hit breaking or off-speed pitches with proper form comprises a barrel shaft with optional foam attachment on a distal end forking into two handles on the proximate end, the two handles each comprising a longitudinal axis not concentric to the longitudinal axis of the barrel shaft. The two handles may be welded onto a non-standard barrel shaft, or alternatively, clamped onto the barrel shaft of an existing bat, and may comprise a U-shaped, L-shaped, or horseshoe-shaped curvature.

A ball bat configured for impacting a ball. The ball bat extends along a longitudinal axis and includes a bat frame and a pivot joint. The bat frame includes a handle portion coupled to a barrel portion. The barrel portions has 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.

The invention describes a bat for baseball or softball having a composite or metallic outer barrel and an insert assembly formed from composite or metallic materials and soft foam materials. The invention describes a number of embodiments of the insert assembly which may include adjustable floating or fixed power cones and adjustable sleeves, as well as a dual wall construction with the radially outer wall having an annular gap to allow limited directional flex of the radially outer wall of the insert assembly upon impact with a ball.

A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes a rod disposed longitudinally in the hollow barrel, a ring attached to the rod, a deformable sleeve disposed around the ring and extending longitudinally in the hollow barrel. The sleeve can include an outer diameter smaller than an inner diameter of the hollow barrel. The bat can include an end cap attached to an end of the hollow barrel and having a recess configured to receive an end of the rod. The rod can be configured to maintain the deformable sleeve in a predetermined suspended position within the hollow barrel such that, when the bat is at rest, the sleeve is disposed a predetermined gap distance from an inner surface of the hollow barrel.
