  • Golf Club Head or Other Ball Striking Device
    Publication number: 20150072799
    Abstract: A head for a ball striking device, such as a golf club head, includes a face member having a face with a striking surface configured for striking a ball and a rear surface opposite the striking surface, a weight member connected to the face member behind the rear surface of the face member, and a resilient member positioned between the weight member and the face member. The resilient member is connected to the rear surface of the face member to connect the weight member to the face member. The resilient member is compressible to permit energy and/or momentum to be transferred between the weight member and the face member through the resilient member during impact, including an off-center impact on the striking surface. Momentum transferred from the weight member to the face member during an off-center impact may reduce energy loss and twisting of the face on impact.

  • Golf club head or other ball striking device with weighted body member
    Patent number: 8968114
    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.

  • Putter heads and putters including a ball striking face body member and a rear body member
    Patent number: 8961334
    Abstract: Putter heads have a ball striking face portion and a rear body portion (as one or more parts). These putter heads may have a DCG/B ratio of at least 0.425 (where B is the overall breadth dimension and DCG is the depth of the center of gravity). Some putter heads may include: (a) a ball striking face body member having a ball striking face with plural openings defined in its central portion; (b) a polymeric material mostly located behind an exterior surface of the ball striking face, wherein a portion of the polymeric material is exposed at the exterior surface of the ball striking face through the openings; and (c) a rear body member engaged with the ball striking face body member. Rear body members or portions thereof can be interchanged to allow for customization and/or better fitting of the putter to the user's putting stroke and/or tastes.

  • Golf club head having a bridge member and a damping element
    Patent number: 8852023
    Abstract: 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.
