A cue or golf club head having a sighting aid, a golf club having the golf club head, and uses thereof.

A chalk-holder for billiard-cues system including a chalk holder having a receptacle including an inner volume and a securing member. The inner volume is configured to store chalk for removeable use. The securing member is configured to engage and be secured at a handle-end of a pool cue for providing ready access to the chalk. The securing member comprises threading. The handle-end comprises an aperture configured to mate with the threading of the securing member. The device may be used to store chalk between uses during billiards.

The present invention relates to two integrated billiard balls for training, which include an image ball and an object ball assembled together by a connecting means and integrated through spherical contact therebetween so that, at the time of billiard training, a trainee can figure out a situation in which the trainee can hit the object ball coupled to the image ball of the training billiard balls, with a predetermined thickness, just by accurately hitting a cue ball while aiming the center of the image ball. Therefore, the present invention enables a trainee to easily practice thickness adjustment of an object ball and thus improve his or her billiard capability.

A configurable butt for a cue stick comprising a body comprising an elongate chamber having an internal thread and a movable weight coaxially located within the elongate chamber and having an external thread, the movable weight being threadingly coupled to the internal thread of the elongate chamber. An internal shaft extends through the movable weight is adapted to rotate the movable weight within the internally threaded chamber thereby causing the movable weight to move between respective ends of the elongate chamber by virtue of the threaded coupling for adjusting a centre of gravity of the cue stick. An indicator arrangement is coupled to the internal shaft and adapted to provide an indicate of the location of the movable weight within the elongate chamber.

Embodiments of a glove including a cut out portion and a reinforcing panel are described herein. In many embodiments, a glove comprises a glove body with a dorsal side, a palmar side, a plurality of finger portions, a thumb portion, and a wrist portion. The wrist portion defines a glove opening in communication with an interior portion defined within the glove body. A reinforcing panel is secured on an outer surface of a palm portion adjacent the wrist portion of the glove body. A cut out portion defines an opening formed through the reinforcing panel and in communication with the interior portion of the glove body to minimize bunching up of the glove body. Other embodiments are also described herein.

Embodiments of golf gloves having a cut out portion and methods to manufacture gloves having a cut out portion are generally described herein. Other embodiments of gloves may be described and claimed.

A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.
