Abstract:
Golf club heads include: (a) a club head body having a ball striking face and defining a rear cavity; (b) a fluid-filled bladder in the cavity; and (c) a retaining member holding the fluid-filled bladder in the cavity. Other club heads include: (a) a club head body having a ball striking face and defining a rear cavity; and (b) an insert member in the rear cavity, wherein the insert member interior includes one or more chambers facing the rear surface of the ball striking face. The chamber(s) may cover at least 30% of a total surface area of the interior surface of the insert member and/or at least 30% of a total interior major surface area of the rear cavity. Golf clubs including these club heads and methods of making such golf clubs and golf club heads also are described.
Abstract:
Described is a set of golf clubs having a unique hosel position and orientation. The hosel position, along with different weight distributions of the clubheads, creates swing energy from a rear of the golf clubhead, maintains a player's hands in a proper position throughout the hitting zone and facilitates straight ball flight. The hosel position near an upper portion of the clubhead near its heel keeps the hosel clear of a clubface thereby providing a unobstructed clubface thus reducing the occurrence of shanks.
Abstract:
Golf club heads having an Al 2 O 3 material impact surface are described. All or a portion of the head may be made of an Al 2 O 3 material, or the Al 2 O 3 material may be in the form of a sheet or insert and applied to a golf club face. Embodiments of this disclosure have an enhanced coefficient of restitution value in the context of collision with a golf ball.

Abstract:
The performance of a golf club (100) may be enhanced through the provision of a void space (102) behind a face plate (104) and above a sole portion (106), to decrease club weight and provide single or combinations of selectable weighting elements within volumetric coordinates of an orthonormal matrix (112) about the void space (102). The weighting coordinates are provided in response to ball strike, flight analysis and physiologic observation of the golf strike swing. Ball backspin, trajectory, penetration and hook or slice may be modified through the use of a definable weighting strategy.
Abstract:
A golf club head having a striking wall, a front surface, a sole portion extending rearwardly from the rear surface, the sole portion having a forward end, a rearward end, an upper surface and a lower surface. The intersection of the upper surface and the rear surface defines an interior sole line. The intersection of the upper surface and the rearward end defines a trailing edge exterior sole line. The upper surface comprises a sink portion having substantial variation in the heel-to-toe contour.
Abstract:
The present invention attempts to replicate in footwear, orthotics, and other products the naturally effective anatomical structures like a bare foot that provide superior flexibility, cushioning, and stable support compared to existing products. More specifically, the invention relates to a device for such products including a unitary internal sipe component, said internal sipe providing increased flexibility for said device. Even more specifically, the invention relates to footwear, orthotic or other products with an outer chamber and at least one inner chamber inside the outer chamber; the outer chamber and the inner chamber being separated at least in part by an internal sips; and the internal sipe providing increased flexibility, cushioning, and stability.
Abstract:
A golf club head designed to act under impact load as a bridge comprising a face (510) ; an inertial support system (520) ; a rear structure (540) ; and a force transfer system (530) , under impact load the force transfer system, in cooperation with the inertial support system, elongating the rear structure and controlling the bending of the face, the pattern of bending of the face being a substantially bridge-like pattern of bending or a substantially modified bridge-like pattern of bending.
Abstract:
A golf club head having a striking wall, a front surface, a sole portion extending rearwardly from the rear surface, the sole portion having a forward end, a rearward end, an upper surface and a lower surface. The intersection of the upper surface and the rear surface defines an interior sole line. The intersection of the upper surface and the rearward end defines a trailing edge exterior sole line. The upper surface comprises a sink portion having substantial variation in heel-to-toe contour, including variation of at least one of: the height of the trailing edge or exterior sole line relative to the height of the interior sole line, measured in vertical alignment; the height of the interior sole line relative to the height of the general outer periphery of the golf club head measured in vertical alignment; the height of the trailing edge or exterior sole line relative to the height of the general outer periphery of said golf club head measured in vertical alignment; and concavity as defined by forward-to-rear contour.
Abstract:
A cavity back golf club head (14) having a bridge member (34) and a damping element (57) is disclosed. The bridge member (34) extends across a first rear cavity (32) connecting a heel (21) and a toe (23) of the golf club head (14) to control the trajectory of a golf ball. For the longer iron clubs, a damping element (57) extends from the sole portion (25) of the cavity back golf club head (14) to the bridge member (34) to define a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the damping element (57) extends from the top portion (24) of the cavity back golf club head (14) to the bridge member (34). The damping element (57) may reduce the vibration and sound of the golf club head (14) upon impact with a golf ball.
