Abstract: A golf club may include a head having a body and a faceplate coupled to the body. The faceplate may have a maximum thickness at a central location and a cross-section intersecting the central location. The cross-section may have continuously variable wall thickness across the faceplate. The faceplate may have a closed non-convex contour curve defined by constant faceplate wall thickness that encloses the central location.

Abstract: A golf club includes a face coupled to a body. A composite axis extends from a heel to a toe of the club and parallel to ground. The face is formed of a fiber composite material including at least first and second sets of ply arrangements. Each of the ply arrangements includes a pair of plies having first and second pluralities of fibers defining first and second angles with respect to the composite axis, respectively. The face has a ball contact surface, an rear surface, and a mid-zone positioned equidistant between the contact and rear surfaces. A majority of the first and second pluralities of fibers of the ply arrangements between the mid-zone and the contact surface are formed of glass fibers, and a majority of the first and second pluralities of ply arrangements between the mid-zone and the rear surface are formed of carbon fibers.

Abstract: An iron-type golf club head includes a body having a wall extending about an opening, a faceplate coupled to the body across the opening, and a fill material. The wall defines a first set of apertures and a second aperture, and includes an outer peripheral surface, a sole and a rear wall portion extending from the heel to the toe. The wall and the faceplate define a rearward-facing back cavity. The sole, the rear wall portion and the faceplate define a lower cavity that is continuous with the back cavity. The first set of apertures and the second aperture extend through the wall from the peripheral outer surface to, and are continuous with, the lower cavity. The first set of apertures and the second aperture extend about first and second planes, respectively. The fill material substantially fills the lower cavity and the first set of apertures and the second aperture.

Abstract: An example pickleball paddle may include a handle and a head coupled to the handle. The head may include an inner layer sandwiched between a first outer faceplate and a second outer faceplate. The inner layer may include a lattice. At least portions of the handle, the inner layer, the first outer faceplate and the second outer faceplate are integrally formed as a single unitary body.

Abstract: An iron-type golf club head includes a body having a wall extending about an opening, a faceplate coupled to the body across the opening, first and second sets of apertures, and a fill material. The wall has an outer peripheral surface, a sole, a toe, a heel, a topline and a rear wall portion extending from the heel to the toe. The wall and the faceplate define a rearward-facing back cavity, and the sole, the rear wall portion and the faceplate define a lower cavity that is continuous with the back cavity. The first and second sets of apertures extend through the wall from the peripheral outer surface to, and are continuous with, the lower cavity. The first and second sets of apertures extend about first and second planes, respectively. The fill material substantially fills the lower cavity and the first and second sets of apertures.

Abstract: The present invention relates to an iron-type golf club head having a lightweight hosel and a high, toe-ward located center of gravity. The golf club head preferably includes a hollow body with a hosel and an interior mold line that extends into the hosel and is separated from a shaft bore by a solid barrier that does not include any through-holes. An upper portion of the body may include a pocket to hold a high-density weight, and the hosel wall may include multiple through-bores to further lighten the hosel. The golf club head may also include one or more internal ribs extending from the hollow interior of the body into the interior of the hosel.

Abstract: A golf club head comprising an adjustable weighting feature including a tube extending from the crown to the sole of the golf club head is disclosed herein. More specifically, a golf club head formed from three pieces, namely a first piece comprising a face, a crown portion, a sole portion, and a hosel, a second piece comprising a rear end, a crown portion, and a sole portion, and a tube, wherein these pieces are welded to one another, is disclosed herein. Each of these pieces may be separately cast, forged, or formed from a metal material such as stainless steel, titanium alloy, and aluminum alloy.

Abstract: The present invention relates to a hosel for connecting a shaft to a club head. In one aspect of the invention, the hosel comprises a body having an undercut, wherein the undercut has a maximum cross section which tapers to a minimum cross section and increases to the maximum cross section immediately adjacent the club head. The hosel further comprises a flange section below the hosel and hosel bore above the undercut, the hosel bore section having a length of at least one inch. In another aspect of the invention, the hosel tapers in diameter from a maximum to a minimum width, and has a maximized interior mold line (IML) to improve bendability and weight savings.

Abstract: A golf club head comprising a channel and an expandable weight that can be removably fixed at any point within the channel is disclosed herein. The weight comprises at least an upper portion, a middle portion, a lower portion, and a bolt, and the upper portion and lower portion preferably are formed of metal materials while the middle portion preferably is formed of a polymeric material. The weight preferably is trapped within the channel so that it cannot fall out of the channel during use. The channel may also have an end that opens into a port, which can be filled with a plug or weight screw to prevent the weight from falling out of the channel, and also can be removed so that the weight can be removed and replaced with another expandable weight having a different overall mass.
