  • Patent number: 5839983
    Abstract: A ball bat grip for improving the gripping action of a batter for baseball or softball, which is useful for left handed or right handed players and which allows the grip to be comfortably adjusted for alignment of the knuckles. The grip includes independent upper and lower grip portions, manually moveable, made of a vinyl, rubber, or rubber-like material for aiding in the gripping power and frictional engagement with a bat surface, whether wood or aluminum bat. The upper and lower grip portions may be installed at the factory or provided with slots for joining the segments onto an existing bat. Finger channels may be included in both the upper and lower grip portions, with the upper grip portion longer, to allow a player to choke up or move the upper hand away from the end of the bat during batting. In an alternative embodiment a single elongated grip is used that can accommodate and receive both hands of the batter.
