  • Publication number: 20190232129
    Abstract: A golf club head comprising a body and a stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The stiffening structure is entirely located within 0.500 inch of a rear surface of the face section measured along a plane normal to the center of the face, and within 1 inch of the center of the face section along a horizontal axis parallel to the face section, and comprises heel and toe connectors connected to one another by a middle connector, such that the stiffening structure has an approximately X- or H-overall shape.

  • Patent number: 10065085
    Abstract: A golf club head comprising a body, at least one weight cartridge, and a plurality of hollow tubes is disclosed herein. The body comprises a face section, a sole section, and a return section, and also defines a hollow interior. Each of the plurality of hollow tubes extends from the return section to the sole section to reduce stresses placed on the face during impact with a golf ball, and the at least one weight cartridge is sized to fit within at least one of the plurality of hollow tubes. The sole section and return section each comprise keyed apertures providing access to the hollow tubes with which they communicate, and the at least one weight cartridge comprises a keyed structure sized to fit through the keyed apertures.

  • Patent number: 9968834
    Abstract: A golf club head comprising a channel and a sliding weight that can be reversibly fixed at any point within the channel is disclosed herein. The channel preferably is disposed on the sole and extends from a heel side of the golf club head, around a rear side, and ends at a toe side of the golf club head. This channel is not constrained to a planar arc, but instead twists as it extends around the golf club head so that it follows the contours, and preserves the aesthetics, of the golf club head. The slidable weight comprises a base portion and a first cap, and a second cap that has the same dimensions as, and is interchangeable with, the first cap is disposed in a pocket in the sole proximate the face of the golf club head.

  • Patent number: 9101809
    Abstract: A face for a golf club head is disclosed herein. The face has an interior surface comprising a central region having a first perimeter having an elliptical shape, an outer edge having a non-elliptical, driver-face profile shape, a first intermediate region located between the first perimeter and the outer edge, the first intermediate region having a second perimeter with a shape that is more similar to the shape of the first perimeter than the shape of the outer edge, and a second intermediate region located between the second perimeter and the outer edge, the second intermediate region having a third perimeter with a shape that is more like the shape of the outer edge than the shape of the first perimeter. The thicknesses of the perimeters of the face disclosed herein may vary around their respective circumferences.

  • Patent number: 8715106
    Abstract: The present invention discloses an iron-type golf club head having features that permit adjustment to the principal moment of inertia angle, the center of gravity location, and overall club forgiveness. In particular, the golf club head includes a rear cavity sized to receive a weight cartridge composed of one or more materials, the adjustment of which changes one or more of the mass properties of the golf club head and may change the interaction of the golf club head with turf during play, and a composite face plate. The weight cartridge may comprise one or more high density materials, and may be located in or proximate the sole.
