Abstract: The present invention is directed to a golf club having a playing characteristic that is communicated to a player based upon a vibration damping material that is colorized and visible from outside of the club head, thereby communicating to a golfer information about the playing characteristics of the club.

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

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: 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 golf club head having a translucent insert disclosed. The club head includes a body defining a striking face, a top line, a sole, a back, a heel, and a toe. The back contains a cavity that extends in a direction substantially perpendicular to the face. A recess is provided within the cavity, with the recess extending away from the cavity and toward the sole. The recess causes more of the club head mass to be oriented towards the perimeter of the club head, and optionally also toward the back of the club head. This enlarges the club sweet spot and increases the moment of inertia, and facilitates imparting a desired flight path to a struck golf ball, producing a more forgiving club. The recess may have a varying depth and/or a varying draft angle. A rear wall of the recess may be provided with a cutout to further reposition mass toward the club head perimeter. A translucent insert, such as a vibration dampening member, may be provided within the recess.

Abstract: A golf club head formed of multiple materials is disclosed. Those portions of the club head that are subject to high stresses during normal use of the golf club head are formed of a metallic material. Most of the material beyond what is required to maintain structural integrity, however, is removed and replaced with a lightweight material. This freed-up mass that can be redistributed to other, more beneficial locations of the club head. The lightweight material also damps vibrations generated during use of the golf club. This vibration damper may be retained in a state of compression to enhance the vibration damping. One or more weight members may be included to obtain desired center of gravity position, moments of inertia, and other club head attributes. An insert formed of multiple materials and having regions of varying thickness may also be included on a rear surface of the club head.

Abstract: The invention provides a golf club head with a truss member that attenuates unwanted vibration while allowing for precise control of mass distribution. In certain aspects, the invention provides a club head with a perimeter body including a top line and a sole portion coupled to a face and a hosel. The club head further includes at least one truss member extending between and coupling two portions of the perimeter body, for example, from the top line to the sole.

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 set of progressive golf clubs with an elliptical pad construction on the back of the striking face that corresponds to a location, shape and size of a predetermined golfer's impact pattern for the lofts and lengths of each of the golf clubs in the set. The elliptical pad progressively changes in location, shape and size from the long irons, to the mid irons, to the short irons, and to the wedges, based on the location, shape and size of a predetermined golfer's impact pattern for each of the long irons, mid irons, short irons, and wedges.

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: 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 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 head with a face insert that is only partially connected to the body of the golf club head is disclosed herein. More specifically, the present invention discloses a golf club head with a face insert wherein the face insert is only connected to the body of the golf club head at specific engagement portions around the perimeter of the face insert while keeping the remainder of the perimeter unengaged. The golf club head disclosed in accordance with the present invention will allow for removal of excessive weight traditionally needed to connect the face insert to the body of the golf club head, therefore improving the performance of the golf club head.

Abstract: A composite material golf club head is provided having a body made from a first metal and a face insert press fitted to a portion of the body and made from a second metal The metals are chosen so that the first metal is heavier than the second metal. The second metal is disposed towards the front and top of the body, and is preferably hard-anodized. In addition, an interlocking structure, for example rectangular or dove tail shaped channels, is provided in the body so that the face insert becomes embedded in the interlocking structure to anchor the face insert to the body. Portions of the golf club head, such as the face insert or sole plate, are anodized to protect against corrosion. The anodized coating is colored to improve aesthetic characteristics or infused with a polymer to increase or reduce friction. Disclosed herein is a golf club head having a body portion and a face insert. The front of the body portion further comprises a cutout sized and dimensioned to receive the face insert.
