Methods and systems for selecting and fabricating individualized golf clubs or golf club components. Using a website, for example, a golfer can input relevant information about his or her golf game, receive recommendations for golf club components, select from the recommendations, and have the desired golf club components manufactured and delivered. In some embodiments, the golf club components include custom golf club heads fabricated using layer by layer processing, such as direct metal laser sintering.

Method and system for sales of golf equipment

Golf club head

The invention provides a golf club head with a fully removable component that can withstand the stress of repeated hits. When assembled, the removable component is held in place by a fastening mechanism that includes structural elements that distribute the holding force across the component and tend to equalize the forces around the periphery where the component meets the body. The fastening mechanism may include a post that reaches across the open space within the hollow club head, pulling the removable component towards an opposed main club head body. Since a golf club of the present invention can be opened, it may include a mechanism on the inside for use by a golfer, such as an electronic device or an adjustment mechanism. The golf club may include a weight adjustment system that allows the club to be custom-fitted to a golfer.

Golf club head with removable component

The invention provides a golf club head that includes a weight adjustment system inside of the club head. Preferably, when the club is played, no part of the adjustment system is directly accessible or exposed to an exterior of the club. The club head may include a panel that opens or is removable, or the club head may be disassembled to provide access to the internal weight adjustment system. A weight adjustment system generally includes at least one mechanism by which a mass distribution of the golf club head can be changed.

Golf club head with accessible interior

The invention includes a releasable component for use on a golf club head, wherein the component itself may serve as a portion of the club head face, crown, sole, or other portion of the club head body when attached to the club head. The component includes an anti-over rotation mechanism configured to prevent overtightening of the component to a corresponding counterbore on the golf club head. The anti-over rotation mechanism is embodied as a taper design defined on a flange of a threaded component and a corresponding taper design on a flange surface of a counterbore. The counterbore is configured to receive and retain the releasable component by way of a threaded engagement, wherein the interaction between the corresponding taper flange designs of the releasable component and counterbore prevents over rotation of the releasable component, particularly resisting rotation due to ball strike impacts.

Releasable threaded component for a golf club having a mechanism for preventing over rotation

The invention provides a golf club head having a port for providing a view into the interior cavity of the club head. The club head further includes at least one rib positioned along an internal surface of the club head and adjacent to the port. The at least one rib is configured to provide sound tuning characteristics, increasing the frequency of the port, thereby improving acoustic properties of the club head, particularly the sound produced by the golf club head during ball impact.

A golf club head having an insert mechanically coupled to a frame. The construction allows a golf club head to be fabricated with a combination of dissimilar materials, resulting in a club head with improved performance. In some embodiments, the insert comprises an outer insert material, an inner insert material, and a sandwiched material. The sandwiched material may be constructed with a plurality of voids having a varying distribution, thereby resembling a biological structure. Methods for forming a golf club having an insert mechanically coupled to a frame are also disclosed.

Golf club head comprising multiple materials

This application generally relates to sets of golf clubs including at least one adjustable club to provide a set with no distance gap. The adjustable club may include a loft-adjustment mechanism and a mechanism to prevent unintended face-angle change. The club is reliable for shots covering the full range of distances associated with multiple loft settings. Thus, an adjustable club can be included in a golfer's golf bag and can play double-duty in terms of the ranges of shot distances it is reliably useful for. In this way, the golfer's bag can contain fourteen clubs that cover all desired ranges between the putter and the driver.

Distance gapping golf club set with dual-range club

The invention generally provides a golf club head having a sole with a region for surface contact such that, when an adjustable club is given different settings, if the club is held at address resting on a surface, the club naturally comes to a rest position in which it exhibits substantially the same face angle in any adjusted setting.

Golf club head with stablizing sole

A releasable connection system for assembling a shaft and a club head, e.g., a golf club shaft and a golf club head. The connection system provides interchangeability between a shaft and a club head and allows the head to be adjusted with respect to the shaft. The mating structures between the shaft and the club head may be indexed for reproducible placement. In an embodiment, the connection system also includes retaining structures that maintain the connection fastener position when the head and shaft are separated.
