Description

  The present invention relates to a golf practice instrument used for swing practice of a golf club, and more particularly to a golf practice instrument capable of hitting a golf ball.

  As a conventional golf practice device, Patent Document 1 discloses a golf club having a club head at the tip of a curved shaft. The shaft is curved so as to form a hand first angle at the time of ball impact by the club head positioned behind the linear axis at the butt end, and the address mark provided on the club head allows the player to It is said that the correct hand first position can be recognized.

JP 2006-504140 A

  The conventional golf training apparatus has a problem that it is difficult for the user to feel a correct swing during the swing because the moment of inertia generated during the swing is as small as that of a normal golf club.

  Accordingly, an object of the present invention is to provide a golf practice device that allows a user to easily experience a correct swing and efficiently learn an ideal beautiful swing.

  The object of the present invention is that a shaft having a curved portion between a body portion and a mounting portion each formed in a straight line, a grip provided on the base end side of the body portion, and the mounting portion are mounted. A head capable of hitting a golf ball, and the curved portion is formed to be shorter than the length of the main body, and when the user soles the head on the ground in an addressed state, This is accomplished by a golf practice device that curves in a circular arc shape with a certain radius of curvature toward the front.

  In this golf practice device, the curvature radius of the curved portion is preferably 1300 to 1500 mm.

  Moreover, it is preferable that the angle which the axis line of the said main-body part and the axis line of the said mounting part make is 15-20 degree in side view.

  According to the present invention, it is possible to provide a golf training apparatus that allows a user to feel a correct swing easily and learn an ideal beautiful swing efficiently.

1 is a side view of a golf practice instrument according to an embodiment of the present invention. It is a front view of the golf practice instrument shown in FIG. It is a front view which shows the modification of the golf practice instrument shown in FIG. It is the figure which looked at the use condition of the golf training instrument shown in FIG. 1 from the user's back.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2 are a side view and a front view of a golf practice apparatus according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the golf practice device 1 is provided with a grip 3 and a head 4 on the proximal end side and the distal end side of the shaft 2, respectively. And the golf ball can be hit with the head 4.

  The shaft 2 is a cylindrical member made of metal, hard resin, or the like, and includes a curved portion 2c between a main body portion 2a and a mounting portion 2b that extend linearly. When the user soles the head 4 on the ground in the addressed state, the bending portion 2c is bent in an arc shape with a certain radius of curvature toward the front of the user. The length of the curved portion 2c is shorter than the length of the main body portion 2a. For example, when the entire length of the shaft 2 is set to 900 to 1000 mm, it can be set to 220 to 230 mm. . If the radius of curvature R of the curved portion 2c shown in FIG. 1 is too large, it will be difficult to feel the moment of inertia during the swing, while if it is too small, it will be difficult to hit the golf ball with the head 4; It is preferable to set the range.

  Both the grip 3 and the head 4 can be the same as a general golf club. The grip 3 is formed with a mark portion 3a such as a line or a character on the upper side in the bending direction of the shaft 2, and is attached to the base end portion of the main body portion 2a. The head 4 has a sole 4a, a face 4b, and a hosel 4c, and is mounted on the shaft 2 by inserting the entire mounting portion 2c into the hosel 4c. The shape of the head 4 is an iron type (for example, No. 7 iron) in the present embodiment, but may be another shape capable of hitting a golf ball such as a wood type as shown in FIG.

  As shown in FIG. 4, the golf practice device 1 having the above-described configuration is such that the user U holds the grip 3 so that the mark portion 3 a faces upward, and attaches the sole 4 a of the head 4 to the ground G to perform golf swing. When the address is taken, the curved portion 2c of the shaft 2 is curved in an arc shape with a constant radius of curvature toward the front of the user, so that both sides of the user U are naturally tightened, and desirable hand down Can be set up. Note that the mark portion 3 a of the grip 3 is not always necessary, and the user U may grip the grip 3 with reference to the bending direction of the shaft 2.

  In the address posture shown in FIG. 4, when the head 4 is solesed on the ground G, the angle α formed between the axis L1 of the main body 2a and the ground G (that is, the lie angle of a general golf club). The golf practice device 1 is formed so that the angle β formed between the axis L2 of the mounting portion 2b and the ground G (that is, the lie angle of the golf practice device 1 of the present embodiment) is reduced. Can be hit. The angle θ (= α−β) formed by the axis lines L1 and L2 is preferably set in a range of 15 to 20 degrees in a side view shown in FIG. 4, so that the moment of inertia during a swing can be experienced. Can be practiced easily, and the practice effect described later can be enhanced.

  When performing ball hitting practice, takeback is started from the state of the above address. If an incorrect opening operation is performed in the initial takeback action, the shaft 2 is bent and the sleeping state becomes large, so that the left side is vacant and the top position cannot be smoothly raised. Therefore, a square initial motion can be experienced naturally.

  Since the moment of inertia in the open direction acts from the middle of the takeback by the curved portion 2c of the shaft 2, the second half of the takeback toward the top position naturally rotates. Due to this rotation effect, the right wrist easily breaks correctly toward the back side, so that the weight of the golf practice device 1 can be easily felt at the top position, and errors such as shaft cross and overswing can be corrected. .

  In a downswing from the top, the left side is vacant when performed in an open state, and the impact is reached with the grip 3 floating, so that the movement of the shaft 2 standing and descending can be understood. Yes, you can do a downswing with the left side tightened. In impact, the square state can be confirmed visually and with a hand sensation depending on the direction of the curved portion 2c.

  In the follow-through after impact, since a large moment of inertia acts on the shaft 2, a correct for-arm rotation becomes possible. Thereby, the folding of the left elbow becomes smooth, and the error that the elbow can be pulled by follow-through can be corrected. As a result, the difference between the finish that has been correctly taken and the finish with the elbow can be felt greatly, and the place and angle of the shaft 2 in the finish can be correctly understood.

  As described above, the golf training device 1 of the present embodiment can naturally perform the entire correct swing when performing the ball hitting practice, so that a beautiful afterimage of the loop is formed around the user U's body. Remaining images of beautiful swings and swing planes are formed. As a result, beginners to advanced players can learn ideal swing efficiently, and swing problems that lead to power loss (hand-up impact, impact away from the body, swing plane swings, downswing) The release delay of the right elbow at the left, the left elbow closing at the follow-through, the loosening of the left grip at the time of impact, etc.) can be eliminated.
