Abstract: A compact putter-type club head comprising a compact body profile and a small strike surface area is described herein. The compact putter head achieves distinct alignment and delivery advantages under a variety of putting conditions and is uniquely suited to produce accurate putting from the rough or fringe. The small body dimensions, including the strike face, force the player to focus on making a center strike, while also providing minimal resistance when travelling through tall grass. Certain features and characteristics of the compact putter head are specifically tailored to produce one of these benefits, while certain other features or characteristics provide benefits across multiple areas.

Abstract: A multi-wheel truck that minimizes wheel interactions with discontinuous and uneven surfaces. The truck provides a suspension system that absorbs impact force caused by uneven surfaces and a unique attack angle that allows obstacles to be traversed when approached from a wide range of angles.

Abstract: Embodiments of golf club weight attachment mechanisms are described herein. In some embodiments, a golf club head comprises a head body with an interior cavity, a shell portion, and a bracket with a weight member coupled to the bracket. In one embodiment, the bracket and the weight member can be configured to be fully contained within the interior cavity. Other examples and related methods are also described herein.

Abstract: 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.

Abstract: Embodiments of headcovers having a headcover body that includes a detachable pull strap with a plurality of leg portions that connect to the headcover body and methods to manufacture such headcovers are generally described herein. Other embodiments of the headcovers may be described and claimed.

Abstract: 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.

Abstract: Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion.

Abstract: Embodiments of collapsible wheels and methods of making collapsible wheels are generally described herein. Other embodiments may be described and claimed.

Abstract: A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

Abstract: A skateboard deck with multiple layers constructed from multiple materials is disclosed. Embodiments for design and manufacture are disclosed.

Abstract: A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

Abstract: Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole. The curved groove pattern provides consistent ball speed performance for any impact location on the putter face.

Abstract: Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

Abstract: Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves extend in a general vertical direction, and intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole.
