Baseball swing training device

Abstract

A baseball swing practicing device according to the present invention includes a fixed weight (20) fixed at one end of a shaft (10), a grip unit (30) fixed at the other end of the shaft (10), a movable weight (42) fitted onto the shaft such that the movable weight moves via centrifugal force along the shaft (10) during a swinging action, an elastic repulsion member (44) fitted to the shaft (10) at the side between the movable weight (42) and the fixed weight (20) to provide an elastic repulsion force for an accurate timing by adjusting the speed where the movable weight (42) collides with the fixed weight (20) in accordance with the swing speed, and a stopper (46) fitted to the shaft (10) at the side between the movable weight (42) and the grip unit (30) to adjust the moving range of the movable weight (42). The baseball swing training device of the present invention enables the timing of an impact moment in a swinging action and the timing of a hitting moment in an actual hitting action to accurately correspond to each other, and allows adjustment of the device in accordance with the ability of the player using the device. The repeated actual swing training not only increases the wrist force but also improves power and swing speed in an efficient manner, and enables a player to visually confirm the impact moment and the arc trajectory during the daytime and the nighttime via the light emitted from a luminous body or a flicker as well as the sound (hitting sound) at the impact moment during the swing training, thus correcting the hitting posture and increasing the concentration at the hitting moment.
