Inventor: KIM KYUNG MIN
IPC: A63B57/30
Filed: 2020-11-18
Abstract: Provided is a golf ball discharge device in which an elevating member is formed on an inside of a flagpole to elevate and lower a ringing board, thereby allowing a golf ball to enter an inside of a hole cup without external interference so that a golf game can be played smoothly. Also, when the golf ball enters the hole cup and collides with the ringing board, a sound is generated from the ringing board so that golfers can easily recognize the sound. A shaft of the elevating member is positioned in a hollow of the flagpole so that a handle on an upper part of the shaft protrudes through an outside of the flagpole, and the ringing board is coupled to a lower part of the shaft by an elastic member so that the ringing board is elevated and lowered. Also, since the golf ball is allowed to enter the hole cup without getting caught in the flagpole or the elevating member and the golf ball placed on the ringing board is discharged from the hole cup, so the golfer can discharge the golf ball without bending the back. In addition, the ringing board is coupled to the elevating member by the elastic member, so that when the golf ball enters the hole cup, the ringing board effectively generates sound by vibration of the elastic member and transmits the sound to the golfer. The ringing board is spaced apart from an upper part of a seating tool, thereby preventing a phenomenon of sticking to the hole cup due to moisture in cold weather such as winter season, and thus the ringing board works smoothly.
