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.

Description

TECHNICAL FIELD[0001]The present invention relates to practice baseball swings applied to practice baseball bats. In particular, to deal with the pitcher's fast pitches the impact using the baseball swing practicing device exactly matches actual hitting moment. The device strengthens the wrist and optimizes the power and speed of the hitter's swing. The strike sound and swing trajectory is visible, which enables the hitter to adjust their swing and enhance their concentration when swinging.BACKGROUND ART[0002]Generally, players use conventional hitting devices that automatically pitch balls or hit a fixed object several times using the bat.[0003]Players practice their swings many times before the actual match to maintain the efficiency of swinging senses.[0004]Currently, players swing two or three bats, according to the hitter, and practice their hitting.[0005]This method is used before the player is actually put into the game because they remember the weight of the bat at practice....

AI Technical Summary

Benefits of technology

[0011]The present invention not only provides hitting sounds at the impact moment during practice regardless of the time, but also provides visual confirmation on the swing trajectory and enhances concentration at the hitting moment.

[0022]Also, the grip unit and shaft are removable, where subsidiary movable weight can be additionally setup or an elastic repulsion member with greater elastic repulsion force can be replaced to the shaft, so that players can adjust according to their abilities.

Problems solved by technology

However, when repeating this method may cause problems in their swinging stance and cause issues that the hitter cannot actually confirm their balance at swinging point and may not perform a proper stance.

However, this type of swinging practice device cannot prepare the hitter for various pitching and fast pitching of the pitcher and also cannot strengthen the wrist and optimize the power and speed of swings, which causes issues hitting and long hitting rates, due to the reason that the movable weight hitting the fixed weight according to centrifugal force does not completely help find the hitting moment.

Furthermore, correcting swinging stances and concentration is a great issue because the impact and trajectory of the swing at day and night cannot be visually confirmed.
