20080293514STRUCTURE OF A GOLF CLUB HEAD OR OTHER BALL STRIKING DEVICE - Ball striking devices, such as golf club heads (including putter heads), have a high moment of inertia about their center, to help prevent twisting and mis-hits, particularly when the ball striking device hits the ball at a somewhat off-center position. The ball striking head of the ball striking device may be structured and/or weighted (optionally with separately attachable weight elements) to have a moment of inertia about a center of the ball striking surface of at least 10,000 g-cm11-27-2008
20090017933Putters with Enhanced Alignment Visualization - Putters and putter heads better camouflage the main body of the head and/or highlight the alignment aid. The top surface of the head (when viewed from a ball address orientation) may be finished in a non-reflective, matte finish, optionally, in a dark color and/or in a color or colors selected so as to blend into or match the color of a golf green. At least some portion of the shaft member may be colored and finished in this same manner. These features help in visualization of the alignment aid (which also may be designed to help in alignment). If desired, the club head and/or shaft color and finish may be customized based on the greens at a specific golf course, greens in a specific geographical region, greens of a specific grass type, greens at a specific time of year or under specific conditions, etc.01-15-2009
20090042664Golf Club Head Having a Bridge Member and a Damping Element - A cavity back golf club head having a bridge member and a damping element is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a damping element extends from the sole portion of the cavity back golf club head to the bridge member to define a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the damping element extends from the top portion of the cavity back golf club head to the bridge member. The damping element may reduce the vibration and sound of the golf club head upon impact with a golf ball.02-12-2009
20090062029Releasable and Interchangeable Connections for Golf Club Heads and Shafts - Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: (a) a cylindrical structure having a cylindrical interior chamber for receiving a golf club shaft, a rotation-inhibiting structure, and a securing structure; and (b) a securing system for releasably engaging the securing structure. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft may be bent or otherwise extend at an angle from the shaft connection assembly so as to allow adjustment of the shaft position with respect to the club head.03-05-2009
20090239679Golf Club Head Having a Bridge Member - A cavity back golf club head having a bridge member is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a wall extending from the sole portion of the cavity back golf club head to the bridge member defines a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the wall extends from the top portion of the cavity back golf club head to the bridge member.09-24-2009
20090286621Putter Heads and Putters Including Polymeric Material as Part of the Ball Striking Face - Putters include a putter body having a ball striking face member made of a material having a first hardness characteristic. A cavity is defined in the putter body behind the ball striking face member, and plural openings are defined in the ball striking face member extending rearward with respect to the ball striking face member and into the cavity. A polymeric material at least partially fills the openings and the cavity, wherein the polymeric material has a second hardness characteristic that is softer than the first hardness characteristic. The ball striking face member and the polymeric material exposed in at least some of the openings provide a ball striking surface of the putter. The ball striking surface may include grooves or scorelines to affect the launch angle, spin, and/or roll of the ball during a putt. Methods for making such putter devices also are described.11-19-2009
20100099511Golf Clubs and Golf Club Heads with Adjustable Center of Gravity and Moment of Inertia Characteristics - Golf clubs, club heads, and club weighting systems may include: (a) a club head body member; and (b) one or more weight members removably and/or movably engaged with the club head body member so as to move between a first position and a second position to change an overall exterior shape of the club head. This shape change may result in changes to the overall center of gravity, weighting, and/or moment of inertia characteristics of the club head. Alternatively or additionally, the weight member(s) may be removed from the club head body member, reoriented, and/or replaced with a different weight member, e.g., to change the overall exterior shape, center of gravity, weighting, and/or moment of inertia characteristics of the club head. Methods of making and using these clubs, club heads, and weighting systems also are described.04-22-2010
20100105500GOLF CLUB FACE WITH SPIN STRIP - A golf club head (such as a putter head), has a face that includes a ball-contacting region. The ball-contacting region has an inset containing an elastically deformable material and at least one rigid element disposed within the elastically deformable material. When a golf ball is struck, the elastically deformable material compresses and the rigid element imparts overspin to the ball that causes it to roll more accurately.04-29-2010
20100113182STRUCTURE OF A GOLF CLUB HEAD OR OTHER BALL STRIKING DEVICE - Ball striking devices, such as golf club heads (including putter heads), have a high moment of inertia about their center, to help prevent twisting and mis-hits, particularly when the ball striking device hits the ball at a somewhat off-center position. The ball striking head of the ball striking device may be structured and/or weighted (optionally with separately attachable weight elements) to have a moment of inertia about a center of the ball striking surface of at least 10,000 g-cm05-06-2010
20100234128Golf Club Face With Spin Strip - A golf club head (such as a putter head), has a face that includes a ball-contacting region.

20100304878Putters with Enhanced Alignment Visualization - Putters and putter heads better camouflage the main body of the head and/or highlight the alignment aid. The top surface of the head (when viewed from a ball address orientation) may be finished in a non-reflective, matte finish, optionally, in a dark color and/or in a color or colors selected so as to blend into or match the color of a golf green. At least some portion of the shaft member may be colored and finished in this same manner. These features help in visualization of the alignment aid (which also may be designed to help in alignment). If desired, the club head and/or shaft color and finish may be customized based on the greens at a specific golf course, greens in a specific geographical region, greens of a specific grass type, greens at a specific time of year or under specific conditions, etc.12-02-2010
20100317451ADJUSTABLE PUTTER ALIGNMENT AIDE - A golf club head with a body and a pivotable alignment aide non-removably housed on a top surface of the body is provided. The pivotable alignment aide is pivotable relative to the top surface and about an axis of rotation transverse to the top surface. The pivotable alignment aide may be coupled to the remainder of the golf club head through a resistive connection and may be shifted to assist a golfer in squaring the face of the golf club face to a perceived eye line and resulting in the golfer being able to better square the golf club head with the eye line at a point of contact. The golf club head may be a golf club head for a putter.12-16-2010
