20100160073 | GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may include a strike face, a rear wall behind the strike face, and a perimeter-weighting element at least partially surrounding the rear wall. The club head may further include an insert, associated with the rear wall and the perimeter-weighting element, having a first portion and a second portion. Preferably, the second portion engages a supplementary component, associated with the perimeter-weighting element and dissociated from the rear wall. | 06-24-2010 |
20100113184 | PUTTER-TYPE GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may include a body comprising a front surface, having an opening therein for receiving a primary insert. One or more secondary inserts may be disposed in the primary insert and may include a leading surface and a trailing surface. The trailing surface may be physically exposed to the elements and the leading surface may be physically exposed and/or visually exposed. | 05-06-2010 |
20100029407 | Golf club head - A golf club may include a front surface, a rear surface having a recess, and an insert at least partially disposed in the recess. The insert may comprise a durometer hardness of less than about 95 Shore A and a cavity having a reinforcement member disposed therein. Preferably, the durometer hardness of the reinforcement member is also less than about 95 Shore A. The insert may further comprise an anterior perimetric boundary having a first length and a posterior perimetric boundary having a second length. The ratio of the first length to the second length may be less than 1 and greater than 0.5. In one example, the insert may have a triangular front profile and a triangular side profile. | 02-04-2010 |
20090239680 | GOLF CLUB HEAD - A hollow golf club head includes a sole, a crown, a skirt, and a striking face. The golf club includes a junction interconnecting the sole, crown, and skirt to the striking face, the junction including at least one stiffening member. | 09-24-2009 |
20090170625 | Set of Golf Clubs - At least three clubs of a set of golf clubs may have an average volume between about 75 cm | 07-02-2009 |
20090149275 | GOLF CLUB HEAD - An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head. | 06-11-2009 |
20090131198 | GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may include a strike face, a rear wall behind the strike face, and a perimeter-weighting element at least partially surrounding the rear wall. The club head may further include a preload spacer associated with the rear wall and a resilient component associated with the perimeter-weighting element. The preload spacer engages the resilient component to provide positive reinforcement of the coupling between the resilient component and the perimeter-weighting element. | 05-21-2009 |
20090124411 | GOLF CLUB HEAD - An exemplary golf club head having additional discretionary mass may be realized by utilizing light-weight materials, an favorable average crown height, and/or articulation points. By using a preferred break length, the additional discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head. | 05-14-2009 |
20090105008 | PUTTER-TYPE GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may include a body comprising a front surface having an opening therein for receiving a primary insert. One or more secondary inserts may be disposed in the primary insert and may include a leading surface, a trailing surface, and at least one intermediate surface. The leading surface may be physically exposed to the elements, the trailing surface may be exposed to the eye, and the at least one intermediate surface may be physically exposed to the elements and/or visually exposed. | 04-23-2009 |
20090088270 | GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may generally include a strike face, a top portion, a bottom portion, a heel portion, a toe portion, and a hosel having a central axis located in an first imaginary vertical plane. A discrete, at least partially curvilinear stiffening element, having generally vertical side surfaces, may be coupled to at least one of the top portion and the bottom portion to improve the dynamic-excitation response of the club head. Preferably, the stiffening element is oriented such that an imaginary horizontal line intersects at least one of the vertical surfaces at at least two points. Additionally, the stiffening element may have at least two inflection points located along a non-linear path characterized by the vertical projection of one of the side surfaces onto at least one of the bottom portion and the top portion of the club head. | 04-02-2009 |
20090075754 | GOLF CLUB HEAD - A golf club head according to one or more aspects of the present invention may include a heel, a toe, a crown, a sole, a strike face, and a lower transition region between the strike face and the sole. The lower transition region may have a plurality of nadir angles progressively increasing in size from the central region of the strike face to the heel and/or toe. The club head may further include an upper transition region between the strike face and the crown. The upper transition region may have a plurality of apex angles progressively increasing in size from the central region of the strike face to the heel and/or toe. | 03-19-2009 |
20080242444 | Golf club head - A golf club head according to one or more aspects of the present invention may include a main cavity having at least one auxiliary cavity and a base surface. An insert may be associated with the base surface and may comprise at least two contact elements, with a bridge member disposed therebetween. Different contact elements of the insert may be disposed in separate respective auxiliary cavities, such that each contact element may be associated with the base surface. The bridge member of the insert may be dissociated from the base surface. Moreover, a surface coating may be selectively applied to the head to permit a durable adhesive bond between the insert and the base surface. | 10-02-2008 |
20080207351 | Strike face insert - A golf club head, according to one or more aspects of the present invention, comprises a metallic striking wall having a striking surface and at least one through score-line opening. At least one complementary component may be disposed rearward of the striking surface such that at least a part of the at least one complementary component extends into only a part of the at least one through score-line opening. | 08-28-2008 |
