Apparatus for Practicing Golf

Abstract

Provided is a target for golf practice. The target for golf practice includes a body, a sensing unit, a visual unit, and a controller. The sensing unit is disposed in the body to sense a trajectory and a speed of a driven golf ball and an impact of the golf ball on the body. The visual display unit is disposed in the body to visually display a result of a movement of the golf ball sensed by the sensing unit through flickering. The controller calculates the result of the movement of the golf ball by the sensing unit to control the flickering of the visual display unit.

What is claimed is: 
     
         1 . A target for golf practice, comprising:
 a body;   a sensing unit disposed in the body to sense a trajectory and a speed of a golf ball and an impact of the golf ball on the body;   a visual display unit disposed in the body to visually display a result of a movement of the golf ball sensed by the sensing unit through flickering; and   a controller for calculating the result of the movement of the golf ball to control the flickering of the visual display unit.   
     
     
         2 . The target of  claim 1 , wherein the visual display unit comprises at least one of:
 a light guide plate for receiving light from a light source to emit light from a surface of the body;   a plurality of light emitting lamps arranged in a concentric circle in the body and controlled so as to independently emit light; and   a plurality of indication light lamps vertically disposed in the body and controlled so as to independently emit light and a plurality of indication light lamps horizontally disposed in the body and controlled so as to independently emit light.   
     
     
         3 . The target of  claim 1 , wherein the controller allows the visual display unit to flicker when the sensing unit senses that the golf ball impacts the body. 
     
     
         4 . The target of  claim 1 , wherein the controller receives information on a wind direction and a speed in a spatial range in which a golfer drives the golf ball and controls the flickering according to patterns for indicating the wind direction and speed through the visual display unit. 
     
     
         5 . The target of  claim 1 , wherein the controller controls the flickering such that a direction of the movement of the golf ball is displayed through the visual display unit when the golf ball forms a movement trajectory deviating away from the body. 
     
     
         6 . The target of  claim 2 , wherein the controller receives information on a trajectory of the golf ball through the sensing unit and displays a result of the trajectory of the golf ball by controlling the flickering of the visual display unit corresponding to the trajectory of the golf ball. 
     
     
         7 . The target of  claim 1 , wherein the body has a through hole and a blocking screen is disposed in the through hole to close the through hole. 
     
     
         8 . The target of  claim 1 , wherein the body is axially attached to a fixing frame and is controlled so as to be folded and rotated toward a rear side when the golf ball impacts the body, and the fixing frame comprises an electric hinge such that the rotated body is restored to an original location. 
     
     
         9 . The target of  claim 8 , wherein the electric hinge comprises a cylinder that comprises an end portion thereof rotatably and axially coupled to the fixing frame and comprises an end portion of a piston rod rotatably and axially coupled to one side of the body.
