Abstract: A golf club having at least one directional based graphic on the golf club it disclosed. More specifically, the golf club in accordance with the present invention will have at least one directional based graphic that will only be visible when the golf club is oriented in a desirable direction while staying invisible in all other undesirable directions.

Abstract: The invention generally relates to golf clubs with sound tuning features. In certain aspects, the invention provides a flanged rib structure configured to provide improved sound tuning characteristics for a golf club head, particularly a hollow-bodied golf club head. In one embodiment, the rib includes a web portion extending from an internal surface of the club head body and a flange portion coupled to a top surface of the web portion. The inclusion of the flange portion to the web portion increases the overall stiffness of the rib, thereby resulting in an increase in the natural vibration frequency of the club head so as to provide a more appealing sound and/or feel upon ball impact, thereby improving the overall sound characteristics of the club head.

Abstract: A golf club head with multi-component construction. The golf club head includes heel and toe portions that generally provide ground contacting surfaces and a raised central region. A portion of a club head wall is spaced away from a second portion of the club head wall by a less than about 2 cm.

Abstract: Golf club heads comprising weighted materials that can be added, removed, and moved in order to change the weight and center of gravity of the club. In some instances, the weighted material is a polymer composition comprising metal and having a specific gravity greater than about 4. Also disclosed are methods of modifying the center of gravity of a golf club head and methods of manufacturing golf club heads.

Abstract: A golf club head having a low-density interchangeable insert located in a top portion thereof. The interchangeable insert may be only in the top line of the club head or extend from the heel around the toe and optionally be visible from above when the club is at address. The interchangeable insert may extend through a hosel and optionally be visible on a heel-side surface. The interchangeable insert may be mounted on a back surface of a striking face, and may extend a distance down the back surface. The interchangeable insert may extend into, and provide part of, a golf ball striking face.

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: The invention generally relates to golf bags. A golf bag of the invention may include a detachable and re-attachable storage compartments. A golf bag may include retractable straps. A golf bag of the invention may include power collection and power plug-in devices.

Abstract: A modular golf club includes a plurality of components that are removably coupled so that the physical attributes of the golf club head may be tuned. The inventive golf club head includes a body member and at least one of a removable sole member and a removable face member.

Abstract: A golf club head with multi-component construction. The golf club head includes heel and toe portions that generally provide ground contacting surfaces and a raised central region. A center of gravity of the club is located outside of an envelope defined by the outer surface of the club head below the raised central region.

Abstract: The invention provides methods and collections of golf clubs that offer a variety of golf club sets from a limited number of golf clubs. The golf clubs are designed such that a golfer can choose one of multiple different, distinct subsets of the collection based on matching the properties of the clubs of the subset to that golfer's needs. In this way, the club maker can provide several different subsets by manufacturing fewer clubs than would be otherwise required. For example, a manufacturer can make one collection of 16 clubs. From that collection of 16 clubs , one golfer could choose a first set of 8 irons, a second golfer could choose a second set of 8 irons, and a third golfer could choose a third set of 8 irons.

Abstract: A golf club can include a universal hosel and/or hosel spacer that allows the golf club to be used with a variety of different sized club head shafts. The universal hosel can include multiple steps or ledges, and various inner diameters to accommodate different sized shafts. The spacer can be a self-expanding spacer, and can be pre-coated with epoxy. The spacer can fill in gaps within a hosel, so as to accommodate different sized shafts.

Abstract: The invention provides a golf club head that includes a weight adjustment system inside of the club head. Preferably, when the club is played, no part of the adjustment system is directly accessible or exposed to an exterior of the club. The club head may include a panel that opens or is removable, or the club head may be disassembled to provide access to the internal weight adjustment system. A weight adjustment system generally includes at least one mechanism by which a mass distribution of the golf club head can be changed.

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.
