Abstract: The present invention generally relates to golf club heads with improved mass distribution provided by novel structural features. The golf club head can include a main club head body and a face member that presents a ball striking face. The face member of the club head has at least one channel located thereon.

Abstract: The invention generally relates to a golf club with a channel area. The channel area includes a groove disposed alongside a ramp having a shallow slope with respect to the horizontal when the club head is at address. The channel area may extend across a portion of the club head such as the crown or the sole. The ramp is oriented such that, during a high speed drive, the ramped portion of the sole may distribute and neutralize torsional stresses, dampening unwanted and unpredictable twisting, preventing the ball from flying in unpredictable directions while the deeper groove contributes to a high coefficient of restitution of a ball-striking face, a large sweet spot area, or both, thus causing the ball to fly a long distance.

Abstract: The invention provides a golf club head with a fully removable component that can withstand the stress of repeated hits. When assembled, the removable component is held in place by a fastening mechanism that includes structural elements that distribute the holding force across the component and tend to equalize the forces around the periphery where the component meets the body. The fastening mechanism may include a post that reaches across the open space within the hollow club head, pulling the removable component towards an opposed main club head body. Since a golf club of the present invention can be opened, it may include a mechanism on the inside for use by a golfer, such as an electronic device or an adjustment mechanism. The golf club may include a weight adjustment system that allows the club to be custom-fitted to a golfer.

Abstract: A releasable connection system for assembling a shaft and a club head, e.g., a golf club shaft and a golf club head. The connection system provides interchangeability between a shaft and a club head and allows the head to be adjusted with respect to the shaft. The mating structures between the shaft and the club head may be indexed for reproducible placement. In an embodiment, the connection system also includes retaining structures that maintain the connection fastener position when the head and shaft are separated.

Abstract: A golf club head with a multi-component construction. The golf club head can include one or more components such as inserts, panels, plates, or body members that fasten to one another to form a club head body or that fasten to a club head body. The club head can include one or more components that snap-fit into a club head body. An insert can be made entirely or partially of plastic.

Abstract: The present invention relates to a golf club, and more particularly to a wood-type club head with a separable body component. In certain aspects, the invention provides a golf club head with a face and hosel body member and one or more of an interchangeable aft body member. The invention further provides a variety of insights and mechanisms for coupling the interchangeable member to the body member.

Abstract: A cover for a golf club is provided having a see-through panel. A club head cover with a see-through panel provides beneficial ease of use in the form of a view of the covered club while protecting the club from dirt, moisture, and damage. A head cover with a see-through panel can be manufactured affordably and include environmentally friendly “green” plastics. A cover further includes optional voids or plastic inserts to optimize flexibility, rigidness, and ease of gripping.
