Title:
BATTING PRACTICING APPARATUS FOR BALL GAME
Document Type and Number:
WIPO Patent Application WO/2006/064681
Kind Code:
A1
Abstract:
A batting practicing apparatus for a ball game, wherein a wire system is divided into an upper wire system and a lower wire system through a hit ball (1), an upper wire (2) and a lower wire (3) are passed through a running block system (5) formed by the combination of a stationary pulley (20) and the running block (21) and fixed at one ends, and the running block (21) receives a pull-back force against a force applied to the hit ball (1) in a flyout direction and retains a pre-tension at the fixed position. Accordingly, since the running block stably and stationarily stands at the fixed position, the hit ball (1) flies along the hit direction (vector) and rapidly returns to the original position and stops without causing swing motion. Also, since the mechanism of the practicing apparatus is simple, the apparatus can be manufactured at low cost.
