Abstract: A metal wood-type golf club includes a weight member disposed along the interior surface of the bottom wall. The weight member is sized and distributed so as to increase the moment of inertia of the golf club about a vertical axis extending through the center of gravity as well as lowering the center of gravity of the club head itself. The longitudinal position of the weight member is selected as a function of the loft angle of the club face. The weight member is moved forward for a club having a small loft angle and moved rearward for a club having a high loft angle so that the vertical gear effect about the center of gravity partially offsets the natural backspin of the club to a greater or lesser degree depending on the loft angle of the club.

Abstract: In a golf bag that includes a body with a top end and a bottom end, a throat structure is mounted in the top end of the body. The throat structure has a substantially ring shaped outer wall and a substantially ring shaped inner wall spaced inwardly from the outer wall. The inner wall defines a first compartment. First and second divider bars extend between the inner and outer walls and are arranged generally parallel to each other to define a second compartment on one side of the first compartment. Third and fourth divider bars extend between the inner and outer walls and are arranged generally parallel to each other to define a third compartment on the opposite side of the first compartment. The first compartment has a generally elliptical shape and is preferably sized to hold a plurality of golf clubs while the second and third compartments each have a generally square shape and are each preferably sized to hold a single golf club.

Abstract: An iron-type golf club head includes a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole. The beveled sole has leading and trailing edges with a ridge located between them. The beveled sole includes a primary surface and a secondary surface, both of which vary in width from the heel end to the toe end. The primary surface is located between the leading edge and the ridge, and the secondary surface is located between the trailing edge and the ridge. The primary surface has a first width dimension adjacent the heel end, a second width dimension measured along a center line located substantially between the heel and toe ends, and a third width dimension adjacent the toe end. The first and third width dimensions of the primary surface are less than the second width dimension of the primary surface.

Abstract: A golf bag has a generally tubular body and a dual shoulder strap assembly for supporting the golf bag on both shoulders of a golfer. The dual shoulder strap assembly includes first and second shoulder straps, and a lower end of the first shoulder strap is received in and connected to a pocket on the body. An elongated plate is located within the lower end of the first shoulder strap so that an upper portion of the first shoulder strap is formed into a loop that extends generally laterally from the body in a standing position to make it easier for a golfer to identify which shoulder strap should be grasped first when preparing to lift the golf bag and carry it.

Abstract: A customizable golf putter head includes a face member and a back body both of which may be selected from a plurality of differently configured face members and back bodies. The face member has a cavity formed in its rear surface, and the back body has a mating section that is positioned within the cavity of the face member so that a parting line between the face member and the back body is concealed below a top ledge of the face member when the putter head is assembled. A hosel selected from a plurality of differently configured hosels is mounted on the face member, and an elastomeric membrane is positioned within the cavity of the face member so as to be interposed between the face member and the back body.

Abstract: A golf club head includes a body with a top wall, a bottom wall, and a front wall arranged for impacting a golf ball. The front wall has an inner surface and an outer surface. The front wall varies in thickness and has a bulging area of increased thickness on its inner surface. The bulging area of increased thickness includes a generally ring shaped mass that projects rearwardly from the front wall. A generally cone shaped mass, that also projects rearwardly from the front wall, may be located inside the ring shaped mass.

Abstract: A golf club having suppressed vibration modes is disclosed. The club comprises a shaft, a golf club head, a grip and a plurality of discrete shaft stiffeners. The shaft stiffeners are strategically located along the shaft so as to shift the nodes of at least the second and third flexural vibration modes of the club shaft such that a node of each of the second and third flexural vibration modes occurs both at the club face and within the region underlying the golf club grip. Preferably, the stiffeners are made of a shape memory alloy that can be shrunk onto the outside surface of the shaft, then expanded to permit the position of the stiffeners to be adjusted to suit the boundary conditions imposed by the human user.
