  • Publication number: 20130324280
    Abstract: A ball striking device, such as a golf club, includes a head that includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearward from the face. A face member formed primarily of a metallic material forms the face, and a body member is connected to the face member and extends rearward from the face member to form at least a portion of the body. The body member is formed at least partially of a polymer material, and has a doped portion containing a doping material dispersed within the polymer material. The doping material may have a different density than the polymer material, such that the doped portion has a different density than the portions of the body member not containing the doping material. A co-molding method may be used to form the ball striking device.

  • Patent number: 8535177
    Abstract: A cavity back iron type club head includes a striking plate having a substantially planar striking surface and a rear surface defining a thickness therebetween. The rear surface defines a striking plate rear cavity region. A perimeter support is coupled to a peripheral portion of the striking plate. The surface area of the striking surface is related to the club head loft angle by the equation SSA?14.4(L)+2875, where SSA is the surface area of the striking surface in units of square-millimeters and L is the club head loft angle in units of degrees.

  • Publication number: 20130225311
    Abstract: This application generally relates to sets of golf clubs including at least one adjustable club to provide a set with no distance gap. The adjustable club may include a loft-adjustment mechanism and a mechanism to prevent unintended face-angle change. The club is reliable for shots covering the full range of distances associated with multiple loft settings. Thus, an adjustable club can be included in a golfer's golf bag and can play double-duty in terms of the ranges of shot distances it is reliably useful for. In this way, the golfer's bag can contain fourteen clubs that cover all desired ranges between the putter and the driver.

  • Patent number: 8506425
    Abstract: A method is disclosed for matching a test golfer with a particular golf club selected from a group of golf clubs having a plurality of styles. The method utilizes data set derived in an initial procedure in which the club style preferences for each of a large number of pre-test golfers is recorded and correlated with a set of performance parameters for the golf swings of such pre-test golfers. This data enables the pre-test golfers to be classified into subgroups, in which golfers within the same subgroup generally prefer the same club style and golfers in different subgroups generally prefer different club styles. After this data set has been established, the test golfer takes a golf swing with a golf club, while performance parameters for the swing are measured. Based on the measured performance parameters and the previously established data set, the test golfer is classified according to swing type, and the optimum golf club is then selected from the plurality of styles of golf clubs.

  • Patent number: 8491407
    Abstract: An iron-type golf dub includes a conventional-weight section, a lightweight section and a heavyweight section. The conventional-weight section includes the hitting face and at least a portion of the hosel. The heavyweight section, made of a denser material than the conventional-weight section, includes the sole and an optional back flange. The lightweight section, made of a material less dense than either of the other sections, includes a core to which the other two sections are secured, such as by co-molding the core to the other two sections. The heavyweight section includes anchoring structures to which the lightweight section can securely attach. This arrangement maintains the overall weight of the club head compared to a similarly proportioned conventional club head while shifting the center of gravity low and aft. As such, the club head provides benefits such as forgiveness for thin shots, heel/toe shots, and provides longer drives with less roll.

  • Patent number: 8480506
    Abstract: A golf club head having a recess located in a top portion thereof is described and claimed. The recess is located between the heel and the toe and extends toward the sole. The recess may be in the top line of the club head. An insert may be placed within the recess. The insert has a density that is less than the density of the club head body, and the insert preferably is a light-weight insert. The insert may include one or more damping materials. The recess removes material from the club head, which in turn may do one or more of the following: increase the overall size of the club head, expand the size of the club head sweet spot, lower the club head center of gravity, and/or produce a greater club head moment of inertia. Thus, the recess and insert produce a more forgiving and playable golf club. As an alternative to a recess, a thin protrusion may be provided at the top line of the club head and the insert provided with a corresponding groove to facilitate attachment.
