Embodiments of golf coupling mechanisms are presented herein. Other examples and related methods are also disclosed herein.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, a plurality of ports on the bottom portion and a plurality of inner wall portions in the hollow body portion. Other examples and embodiments may be described and claimed.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. The golf club head includes a frontal portion and a rear portion formed of a thermoplastic composite material. The thermoplastic composite material is mechanically captured by at least one first attachment feature provided in the frontal portion such that the thermoplastic composite material may be joined to the frontal portion without the use of additional adhesives or external fasteners.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, a plurality of ports on the bottom portion and a plurality of inner support portions in the hollow body portion. Other examples and embodiments may be described and claimed.

A golf club head has a body defining a crown opening and a sole opening, a forward portion of the crown opening having a lip recessed below an outer surface of the crown and extending rearwardly. A composite crown insert is connected to the lip and covers the crown opening. A ratio of an outer surface area of the body and a combined outer surface area of the crown and sole inserts is less than 0.9. The club head has a crown height as measured relative to a ground plane at address, and there is a first crown height at a face-to-crown transition zone, a second crown height at a crown-to-skirt transition zone, and a maximum crown height that is greater than the first and second crown heights, the maximum crown height being located on the crown insert at or rearward of the lip.

A golf club head comprising a ribbed region on at least one of a heel portion, a toe portion, sole, or crown. The ribbed region comprises a ribbed wall with an interior surface facing an interior of the golf club head, and a ribbed wall exterior facing an exterior of the golf club head. The ribbed region further comprises at least one rib protruding from the ribbed region. The first rib comprises a first rib length measured along a rib centerline of the first rib, a first rib interior section located at the ribbed wall interior surface, and a first rib exterior section located at the ribbed wall exterior surface.

A golf club head comprising a channel or a pair of parallel rails and a slidable weight assembly that can be removably fixed at any point within the channel or to the rails is disclosed herein. The slidable weight assembly preferably comprises a weight portion and base that can be turned 45 to 90 degrees to reversibly fix the slidable weight assembly within the channel or to the rails.

A balanced club head includes an encasing with a face plate, a rear side, left and right side, a top side, and a bottom side, defining an interior, right and left inner longitudinal walls, a shaft aperture, a shaft receptacle, a notch in one of the walls, such that the balanced club head is configured to receive a golf shaft, such that the shaft receptacle is configured to receive a lower end of the golf shaft, which protrudes through the shaft aperture with the notch accommodating an angled position of the golf shaft, thereby creating a counter weight and balance that maximizes distance and provides greater accuracy of direction when mounted on a golf club.

A golf club head includes a body, a recessed channel, and a weight assembly. The weight assembly has a weight, a cover, and a fastener coupling the cover to the body. The cover includes a first end, a second end, and a rabbet extending at least partially between the first end and the second end. The rabbet formed by at least two walls and sized and shaped to at least partially receive the weight and allow the weight to slide therein. One or more of the at least two walls have a retention rib extending therefrom. The retention rib is elongated in a direction between the first end and the second end and discontinuous in the elongated direction. The fastener is configured to move the cover between at least two positions, a first position whereby the weight is selectively slidable and a second position whereby the weight is secured.
