Abstract: To provide a bat structure that enables a batter to achieve a system of changing of the grip center position Gc of palm gripping by a bottom hand to Gc1 of palm gripping by bottom hand and a half of upper hands, which leads to move the batting centroids Pc to Pc1. Also, the bat structure is also provided in which by adding a weight ?M (10˜100 gr) to the bat head H of the bat having the grip structure of the kind referred to above, the batting energy at the sweet spot is improved to enhance the impact having the maximum batting effect together with change of the batting centroids Pc to Pc1.

Abstract: [Problem] To supply a composite type bat structure for achieving maximum hitting efficiency [Solution] A composite type bat structure comprises a barrel portion made from a metal cylindrical body for forming a center of percussion, a cap portion attached to the distal end of the barrel portion, a throat portion extending from the rear end of the barrel portion to a grip portion, and the grip portion made from fiber-reinforced plastic (FRP) and having a grip end on the rear end; wherein a distal end opening of the barrel portion comprising the hollow metal cylindrical body is closed by the cap portion, with a prescribed weight being added to the cap portion, so that the center of gravity of the barrel portion in the lower barrel portion is moved toward the distal end of the bat. The FRP grip portion and the FRP grip end are formed separately from each other, thereby allowing an atypical grip shape to be easily formed. The atypical grip has the function of locking the bottom hand at a hitting swing.

Abstract: To provide a bat gripping structure that enables a batter to achieve a proper grip, a grip structure is provided in which the bat is in the “top” position during the take-back of batting, in order to accomplish the swing “to put the bat outwardly from inside” along a line of the bottom hand, a locking structure that enables a lower region (bottom grip) of the grip portion to be gripped at the grip portion of the bat under the palmar grip is employed to provide the grip structure effective to lock the palmar grip of the bottom hand, so that a proper swing to “put the bat out from inside” may be achieved and the angular velocity during the bat swinging is increased. Also, the bat structure is also provided in which by adding a weight ?M (10˜100 gr) to the bat head H of the bat having the grip structure of the kind referred to above, the batting energy at the sweet spot is improved to enhance the impact having the maximum batting effect.

Abstract: A tool for catching a ball having an enhanced function to protect a thumb. A part into which the thumb is inserted is formed as a bag-shaped portion which fits a size of the thumb and which surrounds an entire periphery of the thumb. As another embodiment, a thumb insertion hole can be formed at a location which is on a side of a back of a hand and which corresponds to a joint part of the thumb, and a cover can be installed so as to fit a periphery on the side of the back of the thumb which extends outside from the thumb insertion hole.
