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.

Bat with barrel pivot joint

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.

Knob sleeve for a ball bat handle assembly

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.

A variable stiffness striking implement, such as, for example, a ball bat typically used in baseball, softball, or rubber ball. The striking implement, preferably has a separate barrel and handle. A wedge and joint attached directly to the handle or indirectly to the handle using an interface portion engage the interior surface of the barrel. Most preferably, the wedge and joint are molded about the interface portion and a handle preform is then inserted into the intention of the interface portion and the handle is then molded. Wedge hardness is selectable and a stiffness member may also be employed. Stiffness member hardness may be selectable or may be adjustable by varied adjustment of a cap in relation to the barrel. Alternatively, the cap may not be adjustable in relation to the barrel so that a selected stiffness member hardness is fixed.

Variable stiffness striking implement

An endcap assembly for a bat may include a body across an open end of a bat barrel and a core received by the body. In one implementation, the body and the core may be retained relative to one another by a bayonet connector radially spaced from interior sides of the bat barrel by at least 0.3 inch. In one implementation, the body may include a cup having a mouth and receiving the core. In one implementation, the cup is to be radially spaced from interior sides of the bat barrel by at least 0.3 inch. In one implementation, the mouth is axially recessed. In one implementation, the cup and the core are joined by a bayonet connector having a U-shaped slot facing away from a mouth of the cup.

Bat end cap assembly

A ball bat extending along a longitudinal axis. The bat includes a handle portion, a barrel portion and an end cap. The barrel portion includes a proximal region and a distal region. The proximal region of the barrel portion is coupled to the handle portion by a first pivot joint. The distal region of the barrel portion is coupled to the end cap by a second pivot joint. The first and second pivot joints movably support the barrel portion relative to the longitudinal axis.

A knob sleeve for a ball bat extending along a longitudinal axis and having a tubular handle portion and a knob attached to the handle portion. The knob sleeve includes a tubular body having a distal end and a proximal end. The body defines a central bore for receiving the handle portion. The body includes at least first and second regions positioned adjacent the distal and proximal ends of the body, respectively. The first and second regions have first and second maximum outside diameters, respectively. The second maximum outside diameter is greater than the first maximum outside diameter. Each of the first and second regions has a height measured with respect to the longitudinal axis of at least 0.4 inch.
