A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Adjustable length shaft and an adjustable mass for a golf club

A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.

Skateboard with multi-wheel truck

A golf club head comprising a deflection feature to increase ball speed and launch distance, while producing desirable acoustics and optimized mass distribution. The deflection feature can include any one of or any combination of an insert comprising a gap or an insert comprising voids. The insert manipulates the mass distribution while allowing face deflection and positively damp vibrations in the club head. The deflection feature can also include a thin uniform sole, a cutout in the top rail, optimized face material, a thin sole, a reinforcement device, or a multi material weight. The reinforcement element transfers stress away from the face into the reinforcement device, allowing face element to bend at impact. The multi material weight is a dual-density weight comprising a higher density weight base portion and a lower density weight shell portion.

Golf club head having deflection features and related methods

Adjustable putter shaft stiffener

Described herein is a golf club head comprising a deflection feature to increased ball speed and launch distance, while producing desirable acoustics and optimized mass distribution. The deflection feature can include any one of or any combination of an insert comprising a gap, an insert comprising voids, a thin uniform sole, a cutout in the top rail, optimized face material, a thin sole, a reinforcement device, or a multi material weight. The rear cavity insert comprises voids within the body of the insert providing a change of insert density. The faceplate comprises a reinforcement element allowing the faceplate thickness to be reduced while simultaneously reducing faceplate stress.

Skateboards with a multi-wheel truck

Some embodiments include a golf club head with an insert. Other embodiments for related golf club heads and methods are also disclosed.

Golf club heads with insert and related methods

Golf club heads with cavities and inserts, and methods to manufacture golf club heads with cavities. Various embodiments include a golf club head comprising a body. The body comprises a strikeface at a front of the golf club head, a backface opposite the strikeface, a heel region, a toe region opposite the heel region, a sole, a rear portion at a rear of the golf club head, and a cavity located between the backface and the rear portion. In many embodiments, the body further comprises an insert within the cavity.

Golf club heads with cavities and inserts and related methods

Some embodiments include a golf club head with an arcuate port structure and tuning element. Other embodiments for related golf club heads and methods are also disclosed.

Golf club heads with arcuate port structures and tuning elements

A golf club head and a method of manufacturing a golf club head are described herein. The golf club head comprises a club face with a face portion, and grooves positioned on the club face. The grooves each comprise a bottom, a first side wall adjacent the bottom, a second side wall adjacent the bottom, a first top radius adjacent the first side wall, and a second top radius adjacent the second side wall. The club face further comprises a second portion positioned between the face portion, and the first top radius and the second top radius. The second portion of the club face allows for the grooves to appear visually wider to a player, which can provide psychological effects to benefit performance, while still conforming to USGA groove widths standards.
