  • Publication number: 20260108787
    Abstract: Described herein are embodiments of an iron-type golf club head comprising a rear opening and an insert. The insert either partially or fully occupies the club head interior cavity. The insert damps vibrations occurring within the club head at impact to provide a desirable sound and feel. The insert is formed of a low-density material, thereby providing a significant damping effect while also creating discretionary mass.

  • Publication number: 20260054139
    Abstract: Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.

  • Publication number: 20260021359
    Abstract: Embodiments of mallet-style putter-type golf club heads comprising a first color and an alignment system to draw a golfer's eye towards a particular desirable location are described herein. The alignment system includes a central line extending rearward from a top edge centerpoint toward the rear portion and comprising a second color different from the first color. The alignment system further includes a focus element having a first grouping of lines and a second grouping of lines each extending rearward parallel to the central line and comprising a base abutting a top edge. Each of the first grouping of lines and the second grouping of lines further comprise at least the second color, a color saturation that changes as the lines extend rearward from the top edge, and line lengths that decrease as the first grouping of lines and the second grouping of lines are distributed further from the central line.

  • Publication number: 20250360383
    Abstract: Embodiments of a co-molded putter-type golf club head comprising a high-density chassis made of a first material and a low-density putter-type body made of a second material. The first material can be a high density metal (i.e., steel or tungsten, but not limited to). The second material can be a low density thermoplastic composite (i.e., polyphenylene sulfide (PPS), polyamide (PA), but not limited to). The chassis comprises a flow aperture, and one or more interlocking features. The putter-type body portion encases the entirety of the at least one interlocking feature. Further, the putter-type body encapsulates the chassis such that the body extends through, and completely fills the flow aperture, to interlock the body and chassis, and thus form the club head. Other embodiments may be described and claimed.

  • Publication number: 20250269248
    Abstract: A golf club head includes a rear body having a crown member coupled to a sole member, and a front body coupled to the rear body to define a substantially hollow structure. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. At least a portion of an outer wall of the club head comprises a thermoplastic composite having a plurality of lamina layers. The plurality of lamina layers include at least a fabric reinforced thermoplastic composite layer and a filled thermoplastic layer, and the fabric reinforced thermoplastic composite layer and the filled thermoplastic layer are directly bonded to each other without an intermediate adhesive.

  • Publication number: 20250269254
    Abstract: Described herein are various embodiments of a pickleball paddle comprising a first clamshell component and a second clamshell component. The first clamshell component includes a first head portion, a first rim portion surrounding the first head portion, and a first handle portion. The second clamshell component includes a second head portion, a second rim portion surrounding the second head portion, and a second handle portion. When the first rim portion is joined to the second rim portion, the first and second clamshell components together define a cavity. A core is disposed in the cavity and may be formed of a foam material.

  • Publication number: 20250229144
    Abstract: The golf club head described herein can have a metal body and a non-metal insert. The insert forms an entire toe end of the club head. The insert can have an offset surface, located behind the strike face of the body, wherein the insert and strike face form a gap therebetween. The insert offset surface can comprise a backstop that temporarily restricts bending of a center of the strike face during a golf ball impact. The gap between the strike face and the insert allows the strike face to flex while the backstop prevents the strike face from over flexing. In one embodiment, the golf club head can comprise a body having an interior cavity that opens towards a toe end. The insert can form an outermost surface of the toe end and fill a portion of the cavity.

  • Publication number: 20250177829
    Abstract: A pickleball paddle has a perimeter weighting system to improve performance characteristics and/or to provide swing weighting. The weighting system may include flexible weight strips disposed in recesses formed about a perimeter of the paddle. Alternatively, the weighting system may include slidable weights disposed in one or more channels. The weighting system may further include handle weighting to provide swing weighting. The at least one weight can have a relatively high mass, sufficient to noticeably alter CG of the paddle.
