Golf putting practice device

Abstract

The present invention provides a novel golf putting practice device including a main body portion having at least a half mirror formed in a flat plate shape and a support portion maintaining the main body portion in the air.

1 . A golf putting practice device comprising:
 a main body portion (A) having at least a half mirror ( 1 ) formed in a flat plate shape; and   a support portion (B) maintaining the main body portion (A) in the air,   wherein the support portion (B) has a structure configured to maintain a mirror surface ( 4 ) of the half mirror ( 1 ), which is provided at the main body portion (A), in a substantially horizontal direction.   
     
     
         2 . The golf putting practice device of  claim 1 , wherein the support portion (B) further has a structure that allows an angle of the mirror surface ( 4 ) of the half mirror ( 1 ), which is provided at the main body portion (A), to be changed within 20° from the horizontal direction. 
     
     
         3 . The golf putting practice device of  claim 2 , wherein:
 the main body portion (A) further has a maintaining portion ( 2 ) configured to maintain the half mirror ( 1 ); and   the structure of the support portion (B) that allows the angle to be changed has a coupling portion ( 3 ) between the support portion (B) and the maintaining portion ( 2 ) and allows the angle of the mirror surface ( 4 ) of the half mirror ( 1 ) to be changed with the coupling portion ( 3 ) as a center of rotation by moving an end portion of the mirror surface ( 4 ), which faces the coupling portion ( 3 ), in a vertical direction relative to an installation surface (g) of the support portion (B).   
     
     
         4 . The golf putting practice device of any one of  claim 1 , wherein the support portion (B) has a structure configured to adjust a distance in a direction of gravity (height (h)) from the installation surface (g) of the golf putting practice device to the mirror surface ( 4 ) of the half mirror ( 1 ). 
     
     
         5 . The golf putting practice device of any one of  claim 1 , wherein the mirror surface ( 4 ) of the half mirror ( 1 ) has a substantially rectangular shape whose long side ranges from 5 to 60 cm and whose short side ranges from 2 to 30 cm. 
     
     
         6 . A combination-type putting practice device comprising:
 a golf putting practice device (I) including a main body portion (A) having at least a half mirror ( 1 ) formed in a flat plate shape and a support portion (B) maintaining the main body portion (A) in the air, wherein the support portion (B) has a structure configured to maintain a mirror surface ( 4 ) of the half mirror ( 1 ), which is provided at the main body portion (A), in a substantially horizontal direction, the main body portion (A) further has a maintaining portion ( 2 ) configured to maintain the half mirror ( 1 ), the mirror surface ( 4 ) of the half mirror ( 1 ) has a substantially rectangular shape, the maintaining portion ( 2 ) at least has two flat plates ( 10 ) that are disposed along two long sides of the mirror surface ( 4 ) having the substantially rectangular shape, are parallel to and face each other, and are perpendicular to the mirror surface ( 4 ) while the mirror surface ( 4 ) is disposed therebetween, and upper surfaces ( 11 ) of the two flat plates ( 10 ) are present on the same plane and each have a rectangular shape substantially parallel to the mirror surface ( 4 ); and   a putting practice mat (II) including two linear lines ( 12 ) that are parallel to each other, each have a rectangular shape, and are substantially parallel to long sides of the rectangular shapes of the upper surfaces ( 11 ) of the two flat plates ( 10 ) of the maintaining portion ( 2 ), wherein an inner distance (d 2 ) between two long sides of the rectangular shapes of the two linear lines ( 12 ) is greater than an inner distance (d 1 ) between the two long sides of the rectangular shapes of the upper surfaces ( 11 ) of the two flat plates ( 10 ), and widths (d 4 , d 4 ′) of the rectangular shapes of the two linear lines ( 12 ) are greater than widths (d 3 , d 3 ′) of the rectangular shapes of the upper surfaces ( 11 ) of the two flat plates ( 10 ).   
     
     
         7 . The combination-type putting practice device of  claim 6 , wherein the support portion (B) further has a structure that allows an angle of the mirror surface ( 4 ) of the half mirror ( 1 ), which is provided at the main body portion (A), to be changed within 20° from the horizontal direction. 
     
     
         8 . The combination-type putting practice device of  claim 6 , wherein the inner distance (d 1 ) between the two long sides of the rectangular shapes of the upper surfaces ( 11 ) of the two flat plates ( 10 ) ranges from 20 to 60 mm, the inner distance (d 2 ) between the two long sides of the rectangular shapes of the two linear lines ( 12 ) parallel to each other of the putting practice mat (II) ranges from 50 to 70 mm, the widths (d 3 , d 3 ′) of the rectangular shapes of the upper surfaces ( 11 ) of the two flat plates ( 10 ) both range from 3 to 10 mm, and the widths (d 4 , d 4 ′) of the rectangular shapes of the two linear lines ( 12 ) parallel to each other of the putting practice mat (II) both range from 8 to 12 mm.
