    摘要： Embodiments of golf club heads with face deflection structures are described herein. Other examples and related methods are also disclosed herein. The golf club head described herein can have a deflector located adjacent a front end of the golf club head near a faceplate. The deflector can have front, heel, toe, and rear edges. The golf club head can also have a wave surface with a plurality of external wave troughs and crests. The plurality of external waves are surrounded by the deflector edges. In some embodiments, a forwardmost wave of the wave surface touches or extends to the heel and toe edges of the deflector. In other embodiments, a rearmost wave of the wave surface touches or extends to the heel and toe edges of the deflector.

    摘要： Embodiments of collapsible wheels and methods of making collapsible wheels are generally described herein. The collapsible wheels can each comprise a plurality of wheel sections, a plurality of rims, and spokes connecting the plurality of wheel sections to the plurality of rim portions. The plurality of rim portions are positioned along a perimeter of a circle that defines a central plane of the wheel. Each wheel section supports one or more spokes that connect to one or more of the rim portions. The wheel sections are rotatable relative to each other around an axis from a collapsed configuration to an expanded position. Other embodiments may be described and claimed.

    摘要： Improved skateboards and methods of obtaining or providing skateboards with improved trucks. Trucks have two axles or axes, two primary wheels, and two secondary wheels, and skateboards have eight wheels, four in front and four at the rear portion of the skateboard. The four primary wheels support most or all of the weight of the skateboard when the skateboard is on a flat surface, and the two secondary wheels support the weight of one portion of the skateboard (e.g., front or rear) when the primary wheels cross a crack (e.g., a sidewalk contraction joint). In various embodiments, the secondary wheels are located outboard of the primary wheels. Further, in a number of embodiments, the axis of rotation or axle of the primary wheels remains parallel to that of the secondary wheels, whether the skateboard is going straight or turning.

    摘要： Disclosed herein is a grip comprising an internal bore with an opening having an internal tapered edge. The grip can engage with a tool or a piece of sports equipment. Further disclosed herein is a method of installing a grip onto a tool or piece of sports equipment, including providing a grip having a tubular body; grinding an open first end of the body, wherein the open first end comprises a greatest diameter closest to the exterior of the bore and tapers internally at an angle towards the interior of the bore; providing a shaft or handle; applying an adhesive to a top portion of the handle; sliding the handle into the grip bore until the shaft contacts the a capped second end of the grip; and coupling a surface of the bore to the handle by allowing the adhesive to dry.
