Abstract: A golf club comprises a shaft, a club head, and a connection assembly that allows the shaft to be easily disconnected from the club head. In particular embodiments, the connection assembly includes a removable hosel sleeve that allows a shaft to be supported a desired predetermined orientation relative to the club head. In this manner, the shaft loft and/or lie angle of the club can be adjusted without resorting to traditional bending of the shaft. In another embodiment, the club head has an adjustable sole that can be adjusted upwardly and downwardly relative to the strike face of the club head, which is effective to adjust the face angle of the club head.

Abstract: The present invention relates to golf balls having a low specific gravity core with specific gravities less than 1.05 and one or more high specific gravity intermediate layers with specific gravities greater than or equal to 1.05. The resulting golf balls exhibit significantly decreased spin and long distance and have the added benefit that the high specific gravity intermediate layer can be easily injection molded around the low specific gravity core.

Abstract: A golf club incorporating a stress reducing feature in contact with a shaft connection system socket. The location and size of the stress reducing feature and the shaft connection system socket, and their relationship to one another, selectively increase deflection of the face and maintain stability of the shaft connection system.

Abstract: A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. In some embodiments, the crown includes a lattice-like structure having thin regions surrounded by a web of relatively thicker regions. In some embodiments, the club head includes one or more stiffening tubes attached between the sole and the crown to improve the acoustic performance of the golf club head.

Abstract: This invention pertains to a golf ball which includes a core, optionally one or more intermediate layers; and an outer cover layer, and where one or more of the outer cover or intermediate layers includes a carboxylated elastomer composition, which has an elastomer backbone and one or more pendant carboxy groups.

Abstract: Disclosed herein is a six piece golf ball wherein each part of the golf ball has certain characteristics.

Abstract: This invention pertains to a golf ball which includes a core, optionally one or more intermediate layers; and an outer cover layer. The outer cover layer and/or one or more intermediate layers (if present) includes a blend of from about 2 to about 60 wt % (based on the total weight of the blend composition) of an liquid crystalline polymer (“LCP”) having the general formula; and from about 40 to about 98 wt % (based on the total weight of the blend composition) of one or more additional polymer components.

Abstract: An iron-type golf club head is disclosed having a first piece including a portion of an iron-type face. A second piece including a heel portion, a sole portion, a toe portion, a top-line portion, a hinge region, and a front opening for receiving the first piece is also disclosed. A first contact surface of the first piece is connected with a second contact surface of the second piece at a contact interface. A continuous weld extends along the contact interface attaching the first and second pieces together at the contact interface. The continuous weld includes a fusion zone occurring substantially on the iron-type face outside the hinge region of the club head.

Abstract: Embodiments of a putter-type golf club head with an increased moment of inertia about the X axis (MOIXX) and an increased moment of inertia about the Z axis (MOIZZ) are disclosed. Generally, the MOIZZ is increased by designing the putter such that the center of gravity (CG) of the putter head is located at or behind the geometric center of the putter head. Additionally, the mass of the putter head is concentrated at the outer edges of the putter head. To accomplish this, the ratio of the width of the front of the putter head to the width of the rear of the putter head is no greater than 0.55:1. The MOIXX is further increased by locating the CG relatively close to the bottom of the putter head.

Abstract: A high volume aerodynamic golf club head having a post apex attachment promoting region with a club head volume of at least 400 cc and a front-to-back dimension of at least 4.4 inches producing reduced aerodynamic drag forces. The post apex attachment promoting region is on the surface of the crown section at an elevation above a maximum face height and begins at the crown apex and extends toward the back of the club head. The post apex attachment promoting region is a relatively flat portion of the crown section that is behind the crown apex, yet above the maximum top edge plane, and aides in keeping airflow attached to the club head once it flows past the crown apex.

Abstract: An iron-type golf club head is disclosed having a heel portion, a sole portion, a toe portion, a top-line portion, a front portion, a rear portion, and a striking face. A back wall is also disclosed in the rear portion enclosing a portion of the rear portion to create an enclosed cavity. The cavity is defined by at least a rear surface of the striking face, an inner back wall surface, and the sole portion. A plug and a filler material is located within the enclosed cavity. The filler material surrounds the plug and is configured to hold the plug in place. The plug is lighter than the filler material.

Abstract: A golf club head is provided having a club body having a front portion, a rear portion, a toe portion, and a heel portion. The club head also having a central portion connected with the front portion. A frame is connected with the central portion configured to provide a lightweight crown portion being located above an offset plane.

Abstract: An exemplary golf club head can comprise a body comprising a hosel bore defining a hosel bore axis and an adjustable sleeve comprising a plurality of longitudinal splines that engage with the body within the hosel bore such that the sleeve is configured to be secured within the hosel bore in a plurality of discrete rotational positions relative to the hosel bore axis. The sleeve can further comprise a shaft bore defining a shaft bore axis that forms a sleeve angle with the hosel bore axis when the sleeve is secured within the hosel bore. The square loft angle of the golf club head can be adjusted by changing the rotational position of the sleeve within the hosel bore. The club head can further comprise an adjustable sole piece that can be locked on the sole at a plurality of discrete positions to adjust face angle.

Abstract: A golf club head with an increased moment of inertia (MOI) about the X axis and the Z axis. Generally, the MOI about the Z axis is at least about 4400 g•cm2 and the MOI about the X axis is at least about 2500 g•cm2. The radius of the bulge of the club face is increased while the radius of the roll is reduced to compensate for the gear effect produced by the increased MOIs. The bulge curvature is generally between about 0.016 cm?1 and about 0.028 cm?1, and the roll curvature is between about 0.033 cm ?1 and about 0.066 cm?1. The roll curvature is greater than the bulge curvature.

The body portion defines a front opening and an upper opening, and it includes a sole and a side section that extends rearward of the front opening. The striking plate is secured to the body portion, enclosing the front opening. While partially assembled, final weighting and/or other attachment of other members to the inner surface of the club head can be preformed, as desired. The crown is secured to the body portion, enclosing the upper opening. A surface veil may also be provided about a junction of the crown and body. The crown has a maximum thickness no greater than about 2 mm. The density of the crown is less than the density of the body portion.
