One end of the spring 6 abuts on the flat surface 31. The V-shaped protrusions 32 are formed on the back side of the direction plate 3 from the outer edge of the flat surface 31 every 90 ° outward in the circumferential direction. That is, a total of four V-shaped convex portions 32 that protrude in a V shape so as to form a cross shape from the outer edge portion on the back side of the flat surface 31 are formed. Moreover, the V-shaped convex part 33 is formed along the longitudinal direction slightly to the right of the center of the direction plate 3 shown in the upper part of FIG. These V-shaped convex portions 32 and 33 pivotally support the direction plate 3 with respect to the mounting plate 2 and each V-shaped portion of the mounting plate 2 when the direction plate 3 is positioned along the longitudinal direction. They are formed in a positional relationship such that they fit into the grooves 24 and 26, respectively. Further, the V-shaped convex portions 32 are formed in such a positional relationship that the V-shaped convex portions 32 are respectively fitted into the respective V-shaped grooves 24 of the mounting plate 2 when the direction plate 3 is rotated 90 ° toward the back side of the head 11. ing.

  As shown in FIGS. 3 and 7, the mounting plate 2 and the direction plate 3 are pivotally supported using a bolt 4 and a nut 5 so as to be rotatable with respect to each other. A substantially cylindrical spring 6 is interposed between the direction plate 3 and the nut 5. The bolt 4 has a bolt head 4a having an outer diameter of less than 3 mm and a screw portion 4b. A screw groove 4c (see FIG. 3) is formed at the tip of the screw portion 4b. The nut 5 has a substantially cylindrical outer shape. Further, the circumferential side surface of the nut 5 is knurled for the purpose of preventing slipping or the like. Further, on the back side of the nut 5, there are a large-diameter opening 5a that opens with a large diameter, and a small-diameter opening 5b that is smaller in diameter than the large-diameter opening 5a and is formed from the large-diameter opening 5a toward the front side. Have. A contact portion 5c having a substantially ring shape is formed at the boundary between the large diameter opening 5a and the small diameter opening 5b. A screw groove (not shown) is formed on the inner peripheral surface of the small diameter opening 5b so that the screw 4b can be screwed. As shown in the lower part of FIG. 7, in the state where the bolt 4 and the nut 5 are fastened and the direction plate 3 is rotatably supported with respect to the mounting plate 2, the end surface on the back side of the nut 5 and the surface of the direction plate 3 are A gap G1 is formed between them.

  When assembling the putting auxiliary tool 1, first, the direction plate 3 is placed on the mounting plate 2, and the screw portion 4 b of the bolt 4 is connected to the circular hole 22 of the mounting plate 2 and the circular hole 30 of the direction plate 3. Through the back side. In this state, the bolt head 4a enters the recessed portion 27 and comes into contact with the end surface of the recessed portion 27, and the screw portion 4b protrudes to the front side from both the mounting plate 2 and the direction plate 3 (see FIG. 7). ). Next, the spring 6 is disposed outside the screw portion 4b protruding from the mounting plate 2 and the direction plate 3 (see FIG. 7). In this state, the nut 5 is fastened to the screw portion 4b of the bolt 4. Then, the screw portion 4 b is screwed into the small diameter opening portion 5 b of the nut 5, and the gap G 1 is formed between the end surface on the back side of the nut 5 and the surface of the direction plate 3. Further, as the screw portion 4b is screwed into the small-diameter opening 5b of the nut 5, the spring 6 is pushed down by the contact portion 5c and contracts.

  Thus, when the spring 6 is contracted, the direction plate 3 is pressed toward the mounting plate 2 by the restoring force of the contracted spring 6, that is, the V-shaped convex portions 32 and 33 are in the V-shaped groove 24, 26, the direction plate 3 and the mounting plate 2 are in a parallel state. In this state, as shown in FIG. 2, when the direction plate 3 is rotated 90 ° toward the back side of the head 11, the four V-shaped protrusions 32 and the V-shaped protrusions 33 provided on the direction plate 3. However, it tends to come out from the four V-shaped grooves 24 and the longitudinal V-shaped grooves 26 formed in the mounting plate 2. The force becomes a force that pulls the direction plate 3 upward from the mounting plate 2, and the spring 6 further contracts. When the V-shaped convex portion 32 and the V-shaped convex portion 33 are disengaged from the engagement with the V-shaped grooves 24 and 26, the direction plate 3 is smoothly rotated by 90 °. When the direction plate 3 is rotated by 90 °, the four V-shaped convex portions 32 are again fitted into the four V-shaped grooves 24 and are held in that position. At this time, the spring 6 is in the same state as when the direction plate 3 and the mounting plate 2 are parallel, and the direction plate 3 is pressed toward the mounting plate 2 by the restoring force. The putting auxiliary tool 1 having the direction plate 3 set in this way is attached to the head 11 with a double-sided tape interposed between the face upper end surface 12 and the back surface of the mounting plate 2. As a result, the player can perform putting while confirming the directionality of the target line X using the line guide 29 of the direction plate 3 as a guide. It can also be confirmed whether or not the player's eyes are positioned directly above the golf ball or the sweet spot S on the face with the nut 5 as a mark. The operation of rotating the direction plate 3 by 90 ° toward the back side of the head 11 may be performed after the putting auxiliary tool 1 is mounted on the head 11.

  When the direction plate 3 is parallel to the mounting plate 2, the four V-shaped protrusions 32 provided on one end side of the direction plate 3 are formed into four V-shapes formed on one end side of the mounting plate 2. The direction plate 3 is securely held in a state parallel to the mounting plate 2 by fitting into the groove 24 and fitting the V-shaped convex portion 33 into the longitudinal V-shaped groove 26 formed in the engaging convex portion 21. The Further, when the directional plate 3 is moved 90 ° toward the back side of the head 11 from this state, the spring 6 is pressed and contracted by moving the directional plate 3 upward to disengage from the V-shaped groove 24 and the long V-shaped groove 26. . That is, the four V-shaped convex portions 32 and the one V-shaped convex portion 33 that are fitted into the four V-shaped grooves 24 and the one long V-shaped groove 26 are the rotating convex portion 20 and the engaging convex portion 21. Get on the top. Thereafter, when the head 11 is turned by 90 ° toward the back side, the four V-shaped protrusions 32 are formed again along the longitudinal direction and the short direction of the mounting plate 2. Will fit in.

  As shown in FIG. 4, the player performs putting in a state where the direction plate 3 is moved 90 ° toward the back side of the head 11. In the present embodiment, a case where a right-handed player performs putting is exemplified. For this reason, when the player puts the player's left eye so that it is directly above the nut 5 (vertically above) and the player's right eye is near the tip on the line guide 29, the player can play golf. The ball B (see FIG. 4) is viewed from vertically above, and the face 13 is set at a right angle to the target line X (see FIG. 4) for putting. In this state, if the player swings the head 11 of the golf putter 10 linearly along the target line X direction, accurate putting can be performed.

  In the putting auxiliary tool 1 configured as described above, the direction plate 3 is slid by 90 ° toward the back side of the head 11 with respect to the mounting plate 2, and the line of the direction plate 3 slid to the back side. Putting can be performed using the guide 29 as a guide. For this reason, the player can easily align the face 13 with the target line X at a right angle. Further, the player can confirm whether or not the golf ball B can be viewed from vertically above with the nut 5 as a mark. That is, when the golf ball B is viewed from vertically above, the top view of FIG. 8 is obtained. When the player's eyes are on the shaft side, the nut 5 is on the other end side (head 11). Conversely, when the player's eyes are on the tip side of the head 11, the nut 5 approaches one end side (shaft side) as shown in the lower part of FIG. For this reason, the player can swing the head 11 linearly along the target line X using the line guide 29 and the nut 5 as a guide, and can easily roll the golf ball B along the target line X. It becomes.

  Moreover, the putting auxiliary tool 1 can be attached to the face upper end surface 12 using a double-sided tape or the like. For this reason, it becomes possible to attach the auxiliary tool 1 for putting to the head 11 simply. In addition, since the putting auxiliary tool 1 is provided as a separate body from the golf putter 10, it is not bulky and is convenient to carry. In addition, after the putting auxiliary tool 1 is attached to the head 11, the direction plate 3 is disposed so as to overlap the mounting plate 2 as shown in FIG.

  Further, since the putting assisting tool 1 is configured to rotate the direction plate 3 by 90 ° toward the back side of the head 11, the rotation of the direction plate 3 is not necessary when assisting is not required during putting. It can be used as a general golf putter 10 without being moved, and the assistance of the direction plate 3 can be used only when assistance is required at the time of putting. For this reason, it is possible to determine whether or not the putting auxiliary tool 1 can be used according to the will of the player.

  The putting assisting tool 1 is configured to be assembled by fastening the mounting plate 2 and the direction plate 3 with bolts 4 and nuts 5. Therefore, the player can easily assemble the putting aid 1. Furthermore, since the number of parts which comprise the putting assistance tool 1 is small, it becomes possible to reduce cost.

  In the putting assisting tool 1, the spring 6 is interposed between the direction plate 3 and the nut 5, and the urging force of the spring 6 is used to connect the V-shaped convex portions 32 and 33 of the direction plate 3 to the mounting plate 2. The direction plate 3 is positioned with respect to the mounting plate 2 by being fitted in the V-shaped groove 24. For this reason, it is possible to position the direction plate 3 with a simple structure.
