Abstract

Abstract This invention relates to an improved structure for a racket handle, particularly denoting a design which has a hooking/gripping and force applying point for the forefingers and separate areas for the hooking/holding of the middle, the force and the little fingers set in a descending order from the upper direction of the racket handle. Also designed are a circular swollen convexed section to facilitate the handle-holding motion performed by the center of the palm and the section of hypothenar emience keeping in close touch with the handle to provide similar functions to facilitate the performance of handle holding. This unique design will keep the palm of the player in close and comfortable touch with the racket handle and further match it with the natural structure of the elbow when a ball is being struck, so as to reduce the possibility of sporting injury and help beginners form a proper handle-holding posture to the ultimate end of bringing the skill of racket playing to its full play.
