  • Patent number: 10195497
    Abstract: An oversized golf club head and golf club having a large volume, large head dimensions, and/or large face characteristics, as well as unique mass property attributes driven by relationships not often considered in conforming club head design, to achieve a resistance to squaring the oversized club head during a golf swing that is comfortable to the novice golfer, a feel similar to a non-oversized golf club, stability during off-center impacts, and preferred launch characteristics. This is achieved in part via establishing a club head configuration and associated center of gravity location that results in a preferred magnitude of Delta1 and Delta2 values, CG angle, moments of inertia, and associated ratios, relationships, and club head mass property characteristics influenced by these variables, to account for the significant scale of the oversized club head and achieve improved performance.

  • Patent number: 9266000
    Abstract: A golf club includes a tubular shaft, a golf club head affixed to a first end of the tubular shaft, and a grip disposed about the tubular shaft and abutting a second end of the tubular shaft. An adjustable counterbalance extends within a hollow recess of the shaft and is selectively secured to the second end. The adjustable counterbalance includes an elongate member and an annular weight disposed about the elongate member. The annular weight is movable along the elongate member and configured to be selectively affixed to the elongate member.

  • Patent number: 9192833
    Abstract: A golf club with improved weight distribution is disclosed herein. More specifically, the present invention discloses a golf club with a lightweight shaft allowing the golfer to achieve higher swing speed, while shifting the weight savings of the shaft to a grip portion of the club; counterbalancing some of the undesirable performance characteristics associated with a lightweight shaft.

  • Patent number: 9155945
    Abstract: Clubs and clubheads are disclosed that allow the swing-weight thereof to be easily changed by attaching or exchanging a “weight-assembly” having a first portion configured as a “weight insert,” a second portion configured as an overcap, and a third portion configured as a drive screw. The drive screw extends through the overcap and into the weight-insert to assemble the weight-assembly, which fits into a weight-receiving cavity on the clubhead. These three components are made of respective materials (having respective densities) that are selected so that each component contributes a desired fraction of the total mass of the weight-assembly to the clubhead to achieve a desired change in swing-weight. By mix-match selection of the components, a wide range of masses of the weight assemblies can be made, with small increments therebetween.

  • Patent number: 8998742
    Abstract: The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The long irons have a first center of gravity positioned horizontally from the face center by a first distance. The mid-irons have a second center of gravity positioned horizontally from the face center by a second distance. The short irons have a third center of gravity positioned horizontally from the face center by a third distance. The first distance and the second distance are preferably similar and the third distance is at least about 30 percent greater than the first and second distances. Preferably, the first and second distances are between about 1 mm and 3 mm and the third distance is between about 3 mm and 4 mm.

  • Publication number: 20150087434
    Abstract: A golf club set 2 includes a plurality of golf clubs 41 to 45 having different club lengths. Each of the golf clubs 41 to 45 includes a head 6, a shaft 8, and a grip 10. The club length of each of the clubs 41 to 45 is 38.5 inches or greater and 42 inches or less. Face progression of the head 6 is substantially constant. If a moment of inertia of the head about an axis line of the shaft is defined as MI, an MI difference ratio between the adjacent clubs is equal to or less than 3%. Preferably, a loft angle is equal to or greater than 17 degrees in each of all the clubs 41 to 45.

  • Patent number: 8974317
    Abstract: The present invention discloses an iron-type golf club head formed from multiple materials that increase torsional stiffness of the club and aid in sound performance. In particular, the iron-type golf club head includes a rear flange and a composite component bonded to an external surface of the rear flange. The composite component may cover an entire surface of the rear flange, and may also extend upwards to make contact with a top portion of the club head and thus close off a rear cavity of the club head. The iron-type golf club head may further comprise a face support structure extending from the rear flange, to which the face plate may be affixed via welding or brazing.

  • Patent number: 8951141
    Abstract: A set of iron-type golf clubs and a set of iron-type golf club heads are disclosed. The loft angles of the heads are gradually increased from the lowest numbered golf club to the highest numbered golf club in the set. Given that a coefficient of inertia of the head is the ratio Ms/M of a moment of inertia Ms (gram sq·cm) of the head around a horizontal axis extending in a toe-heel direction of the head passing through the center of gravity of the head, to the mass M (g) of the head, the coefficient of inertia is gradually increased with the increase in the loft angle, and the difference of the coefficient of inertia of the head of the highest numbered club from that of the lowest numbered club is 0.3 or more.

  • Publication number: 20150038251
    Abstract: In accordance with the present invention, a set of golf club heads is disclosed. The set includes golf club heads with peripheral weights. The dimensions and configuration of at least the peripheral weights are changed from club-to-club along the set so that the center of gravity rises from the long irons to the short irons. By raising the center of gravity from the long irons to the short irons, a golfer will see a peak trajectory height along a line for each club head that is substantially more consistent along that line throughout the set than prior art clubs provide.

    Abstract: Golf club heads which include an iron type golf club head body include a ball striking face, a rear surface opposite the ball striking face (e.g., including a perimeter weighting member) and a multi-legged bridge member which indicates the location of the center of gravity of the golf club head body. Golf clubs including these club heads and methods of making such golf club and golf club heads also are provided.
