  • Publication number: 20140274449
    Abstract: Described herein are embodiments of golf club heads, such as fairway wood heads, having an adjustable sole. In some embodiments, a club head includes a body, a sole plate, and a platform. The body has a front portion comprising a striking plate, a rear end, a toe, a heel, a crown, and a lower portion opposite the crown. The sole plate is coupled to the lower portion of the body and is pivotably adjustable relative to the body about a pivot location adjacent to the front portion of the body. The platform is positioned between the sole plate and the lower portion of the body and is adjustable, such as frontwardly and rearwardly, to plural positions along the lower portion of the body to change a pivot angle between the sole plate and the body.

  • Patent number: 8827830
    Abstract: A golf club head designed for an open face approach is provided. Several factors encountered when hitting a ball from an open face position are addressed by the disclosed club head. As a result, precision, spin rate, loft, and stopping power are significantly improved from an open face strike. The club head includes a club face having a plurality of parallel, non-intersecting grooves extending across the club face and offset at an angle to optimize backspin and minimize sidespin when a ball is struck in the toe region. The club head also provides a sole and/or trailing edge designed to accommodate an open face position and to avoid “thinned” shots.

  • Publication number: 20140221123
    Abstract: A golf club apparatus includes a shaft, a grip and a head. The head is attached to the shaft. The head further includes a main body having a ball contacting surface or club face; a heel portion, a toe portion and a sole portion. The shaft attached to the main body proximate the heel portion and the toe portion is distal from an attachment point of the shaft. The sole portion corresponds to the bottom of the main body and is positioned between the toe portion and the heel portion and the leading edge to the trailing edge. A leading edge is an edge formed at the intersection of the club face and the sole portion. The sole portion has a plurality of substantially triangularly shaped or v-shaped grooves therein with axes. Each of the axes is between 0 degrees and 180 degrees to the plane of the club face. This angle is also combined with varying levels of bounce, camber, radius and sole width creating various options within a certain degree of a wedge or iron.

    Abstract: A golf club head includes a body member having a ball striking face, a crown, a toe, a heel, a sole, a rear, and a hosel region. The heel includes an airfoil-like surface shaped like the leading edge of an airfoil that extends over a majority of the length of the heel. The back may include a Kammback feature having a concavity extending from the heel-side to the toe-side of the back. The heel-side edge of the concavity may be shaped like the leading edge of an airfoil. Further, the sole may include a diffuser that extends at an angle of from approximately 10 degrees to approximately 80 degrees from a moment-of-impact trajectory direction. A hosel fairing that extends from the hosel region toward the toe may also be provided on the crown. A golf club including the golf club head is also disclosed.
