Down-blow swing practice apparatus

Abstract

The present invention relates to a down-blow swing practice apparatus comprising: an object to be hit-part of which a portion protrudes from a curved part formed on a part spaced at a predetermined distance in the proceeding direction of a golf ball from the position, at which the golf ball is put, on the upper surface of an artificial turf mat and protrudes upwards from the artificial turf mat in correspondence to the strength of the force applied through a leading edge of a golf club head only when a person who is practicing takes a desirable down-blow swing; and a returning part formed in the direction opposite to the object to be hit-part so as to return the state of the object to be hit-part into the state before swing practice, wherein the object to be hit-part protrudes only when the person who is practicing takes an accurate down-blow swing, and thus the person who is practicing can practice the accurate down-blow swing.

1 . A down-blow swing practice apparatus comprising:
 a body ( 20 ) provided under an artificial turf mat ( 10 ) to support the artificial turf mat ( 10 ), the artificial turf mat ( 10 ) being configured to support a golf ball placed thereon;   a strike unit ( 40 ) configured such that a portion thereof protrudes from a concave portion ( 10   a ) formed at a predetermined distance from a spot on a top surface of the artificial turf mat ( 10 ), on which the golf ball is to be placed, in a moving direction of the golf ball and configured to protrude further upwards from the artificial turf mat in proportion with a magnitude of force applied by a leading edge of a head of a golf club when a golf trainee performs a down-blow swing; and   a returning unit ( 50 ) provided opposite the strike unit ( 40 ) to restore a state of the strike unit to an initial state before a swing practice,   wherein the strike unit ( 40 ) includes:   a protruding part ( 41 ) configured to be struck by the leading edge of the head of the golf club when the golf trainee performs a down-blow swing; and   a strike line ( 42   a ) connected to two ends of the protruding part ( 41 ) and disposed inside the body ( 20 ) supporting the artificial turf mat ( 10 ).   
     
     
         2 . The down-blow swing practice apparatus according to  claim 1 , wherein the protruding part ( 41 ) of the strike unit is formed in an arc shape. 
     
     
         3 . The down-blow swing practice apparatus according to  claim 1 , wherein the protruding part ( 41 ) includes a covering material for enveloping the strike line. 
     
     
         4 . The down-blow swing practice apparatus according to  claim 1 , wherein the body ( 20 ) includes:
 a rubber plate ( 21 ) disposed under the artificial turf mat ( 10 );   a rubber bar ( 22 ) provided at a bottom surface of the rubber plate ( 21 ) to support the artificial turf mat ( 10 ) and the rubber plate ( 21 );   a support part ( 23 ) provided under a portion of the artificial turf mat ( 10 ) that is located slightly ahead of the spot on which the golf ball is to be placed, configured to be elastic enough to allow the artificial turf mat ( 10 ) to be pushed down in accordance with a degree of impact applied thereto by the leading edge ( 200   b ) of the head ( 200   a ) of the golf club ( 200 ), and configured to be pushed down in accordance with a degree of impact applied by the golf club when the golf trainee performs a down-blow swing; and   a connection part ( 24 ) for receiving the returning unit ( 50 ) inserted thereinto.   
     
     
         5 . The down-blow swing practice apparatus according to  claim 4 , wherein the returning unit ( 50 ) includes:
 two guide rails ( 51   a  and  51   b ) extending from the connection part ( 24 ) and connected at ends thereof to each other;   a returning line ( 42   b ) configured to be moved in a moving direction of the golf ball by protruding movement of the strike unit ( 40 ) and to be moved in a reverse direction by external force applied thereto, the returning line ( 42   b ) forming a separate closed loop at a position opposite the strike line ( 42   a ) of the strike unit ( 40 ); and   a rotary roller ( 52 ) configured to receive the strike line ( 42   a ) and the returning line ( 42   b ) so that the strike line ( 42   a ) and the returning line ( 42   b ), extending along the two guide rails ( 51   a  and  51   b ), pass through the rotary roller ( 52 ).   
     
     
         6 . The down-blow swing practice apparatus according to  claim 4 , wherein the returning unit ( 50 ) includes:
 two guide rails ( 51   a  and  51   b ) extending from the connection part ( 24 ) and connected at ends thereof to each other;   a returning line ( 42   b ) configured to be moved in a moving direction of the golf ball by protruding movement of the strike unit ( 40 ) and to be moved in a reverse direction by external force applied thereto, the returning line ( 42   b ) forming a separate closed loop at a position opposite the strike line ( 42   a ) of the strike unit ( 40 ); and   a rotary roller ( 52 ) configured to receive the strike line ( 42   a ) and the returning line ( 42   b ) so that the strike line ( 42   a ) and the returning line ( 42   b ), extending along the two guide rails ( 51   a  and  51   b ), pass through the rotary roller ( 52 ).
