A sporting implement, such as a blade for a hockey stick, may include an outer layer, a core, and a recovery gel positioned between the core and the outer layer. The recovery gel can form a film, and the recovery gel can be compressible, shape recoverable, and pressurized to a predetermined pressure. The recovery gel can be configured to provide an integrated agent for filling cracks that appear during use of the blade. The recovery gel can be configured to absorb energy impacts between the outer layer and the core. When a crack appears, the predetermined pressure can be relieved inside the crack and fills a cavity formed by the crack to provide cohesion between the outer layer and the core to recreate a new material in the place of the crack. The recovery gel can be configured to help prevent cracks from propagating and actively heals potential damages by reducing stiffness loss caused by cracks.

A golf club head has a body member and a sole plate member where each form a portion of the sole surface of the golf club head. A layer of resilient material is disposed between body member and the sole plate member.

A grip device is disposed on a handle of a piece of equipment. The grip device includes a lower concave surface contacting the handle and a lower concave surface oriented away from the handle. An adhesive tape is wrapped around the handle and grip device in one embodiment. In another embodiment, an adhesive layer is disposed between the handle and grip device. The lower concave surface includes a first taper at an end of the grip device oriented toward a knob of the handle. The upper convex surface includes a second taper at an end of the grip device oriented away from the knob of the handle. The grip device bends to follow a curvature of the handle.

A ball bat includes a barrel in which one or more stiffening elements or damping elements, or both, are located. The stiffening or damping elements may be positioned at a variety of locations, and may have a variety of configurations, for selectively reducing the barrel's performance without appreciably increasing the bat's moment of inertia.

A training bat having an elongated barrel of a substantially rectangular cross-sectional shape, a relatively short tapered section and a handle section with knob, wherein the hitting surface is substantially flat with rounded edges and is of a lesser width front to back than each side of the barrel and provides a relatively longer than the hitting surface of a standard bat having a standard cylindrical shaped barrel. The hitting surface and is oriented relative to the grain of a wood embodiment such that the grain of the bat will be perpendicular to the ball at contact. The elongated barrel and short tapered section create a longer sweet spot which extends further toward the handle than a standard bat. The barrel has uniformly perpendicular sides extending from the tapered section to the top of the bat.

A barrel of a baseball or softball bat is coupled to an end of a handle of the bat by means of a vibration absorber affixed to the end of the handle. Projections of a first locking section of the vibration absorber engage with depressions formed on an inner surface of the barrel. Adhesive disposed within gaps and channels of the vibration absorber adhere the vibration absorber to the barrel. A second locking section of the vibration absorber is attachable to a sleeve disposed over the handle. The sleeve may be of a material having shock absorbing or dissipating characteristics.

The present invention relates to a practice swing bat and, particularly, to a bat which is capable of, during golf swing practice, calculating and displaying swing speed, virtual driving distance of each club, etc., and transmitting the same to a terminal so as to enable management of the same. To this end, the bat of the present invention comprises a swing measurement module.

A ball bat barrel has an interior surface and a luminescent layer on the interior surface. The luminescent layer, upon being charged, emits light that indicates tampering with the interior surface.

Embodiments of golf clubs with adjustable loft and lie and methods of manufacturing golf clubs with adjustable loft and lie are generally described herein. The invention relates in particular to a golf club head with an adjustment portion that allows a user to change the loft and lie. The separate adjustment portion of the club head can couple the upper hosel to the body at a plurality of positions. An insert part of the adjustment portion has an upper section for receiving the upper hosel portion, a middle section, and a lower section. The sections of the adjustment portion can be coupled together by a fastener so that the sections are rotationally movable.

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.
