Description

  The present invention relates to a golf shoe suitable for a golf swing that does not twist the body.

  Non-Patent Document 1 discloses a golf swing theory that does not twist the body. The theory is that the knee is bent forward, the toes are weighted, the weight is applied to the toes, the body is addressed in an unstable state, that is, the body moves cheaply, and in the case of right-handed, the backswing is turned to the right and the luggage is held with both hands. In this state, the hand is lowered while rotating the body, and in the follow swing, the player is directed to the left and lifts the load with both hands again.

  The above golf swing theory is conscious of the center of the body and does not involve arm strength or excessive wrist return, so even a weak woman or an elderly person with a hard body can obtain a sufficient flight distance and stable directionality. It is supposed to be done.

In order to practice the above golf swing theory, a shoe with a rotation function is preferable because the entire body is rotated without twisting the body. Examples of shoes having such a rotation function are disclosed in Patent Documents 1 to 4.

In Patent Document 1, a turntable provided on a shoe sole is coupled to a shoe sole by an elastic web provided on the periphery, and the elastic web elastically responds to rotation in any direction from a rest position of the turntable. A structure that can be deformed and applies an elastic bias so that the turntable returns toward its rest position has been proposed.

In Patent Document 2, a sole hole is provided in the shoe sole of the toe and the heel, an upper plate is attached to the inside of each bottom hole, and a central shaft is attached to the center of the upper plate in a direction perpendicular to the shoe sole. A structure for mounting a rotating body is disclosed.

Patent Document 3 proposes a shoe in which a root portion of a shoe sole toe of a shoe is formed thick, a mounting bracket is provided on this portion, and a rotating adapter is attached to the mounting bracket, thereby enabling rotational movement. .

In Patent Document 4, as a footwear such as a sandal, a rotating disk is disposed below the footrest member, a rotation axis is formed between the footrest member and the rotating disk, and the footrest member rotates with the rotation shaft. A structure in which a board is connected is proposed.

Japanese National Patent Publication No. 11-513286 JP 2005-95283 A JP 2005-124688 A JP 2006-192226 A “Don't twist, fly far, stop by the pin” by Tetsuhito Masuda Golf Digest New Book issued on December 16, 2007

The shoe disclosed in Patent Document 1 cannot be applied to a swing in which the turntable can rotate only slightly and the body is not twisted. Also, it cannot rotate around the base of the big toe.

In the shoes disclosed in Patent Documents 2 to 4, it is difficult to grasp how far the shoe has been rotated. It is difficult to determine the end point of the backswing, and the start of the swing is difficult to grasp.

Also, in order to stabilize the center of the body and rotate the whole body without twisting, the base of the big toe must be centered, but none of the prior art has such a structure. For example, in Patent Document 3, the rotation adapter is attached at the base of the finger, but specifically, the rotation adapter is attached to the center of the width direction of the shoe so that the rotation around the base of the big toe is possible. Can not.

In order to solve the above problems, the golf shoe according to the present invention is such that the front surface of the shoe sole is an inclined surface that rises forward toward the tip so that the heel portion floats while standing on the tip of the toe, and the base of the thumb of the foot of the inclined surface. A rotation mechanism having a rotation center located at a portion directly below the rotation mechanism, the rotation mechanism including a receiving member fixed to the shoe sole and a rotating member rotatably supported by the receiving member. An inner space is formed between the rotating member and the receiving member by forming a cap shape or the rotating member having a cup shape, and the rotating member includes a dividing plate that divides the inner space into left and right spaces. And a resilient member compressed by the dividing plate as the rotating member rotates is accommodated in each of the left and right spaces.

In addition to rubber, the spring member may be a spring, a disc spring, gas, or the like, and the setting is preferably made so that the compression member reaches the compression limit in a state in which the rotating member is rotated 90 degrees left and right from the neutral position. .

According to the golf shoe of the present invention, accurate directionality and sufficient flight distance can be ensured without twisting the body, which is optimal for women and elderly people. In addition, since it does not twist the body, it does not put a burden on the waist, and it is also effective for golfers who suffer from back pain.

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a golf shoe according to the present invention, and FIG. 2 is a view showing a bottom surface of the golf shoe.

The front portion 3 of about 1/3 to 1/2 of the entire shoe sole 2 of the golf shoe 1 is inclined upwards toward the tip so that the heel portion floats in a state where the toe stands up, and this portion has a rotation mechanism. 4 is provided.

The rotating mechanism 4 includes a receiving member 5 and a rotating member 6 fixed to the shoe sole. The receiving member 5 has a cap shape, and a screw shaft 7 is attached to the center. The rotating member 6 has a disc shape, and a cylindrical portion 8 is formed at the center, and a projection 9 serving as a spike is formed on the lower surface. A gap is formed between the cylindrical portion 8 and the screw shaft 7 in a state in which the cylindrical portion 8 is externally fitted to the screw shaft 7, and a cap nut 10 having a female screw portion formed on the inner peripheral surface is provided in the gap. By wearing, the rotating member 6 is rotatably held by the receiving member 5.

Since the rotation mechanism 4 has a cap shape partially closed by the wall 11, an internal space is formed between the rotation member 6 and the receiving member 5 while holding the rotation member 6. The internal space is divided into left and right spaces S1 and S2 by a dividing plate 12 provided in the space, and a resilient member 13 such as rubber is accommodated in each of the spaces S1 and S2.

The rotating member 6 and the receiving member 5 are brought into close contact as much as possible so that dust or the like does not enter the spaces S1 and S2. Further, in order to form a space, if the shape of the receiving member 5 is made cup-shaped, dust and the like are more difficult to enter.

The elastic member 13 is selected such that, for example, the rotating member 6 reaches the compression limit in a state where the rotating member 6 is rotated 90 degrees to the left and right from the neutral position.

Next, the operation of the golf shoe according to the present invention in accordance with the actual swing will be described with reference to FIGS. Here, FIG. 3A is a diagram showing the position of the golf shoe at the time of addressing, FIG. 3B is a diagram explaining the relationship between the rotating body and the resilient member at the time of addressing, and FIG. The figure which shows the position of the golf shoes of FIG. 5, (b) is the figure explaining the relationship between the rotary body at the time of backswing, and a resilient member, FIG. 5 (a) is the figure which shows the position of the golf shoes at the time of a follow-through. b) is a diagram illustrating the relationship between the rotating body and the elastic member during follow-through.

  First, in the address state, as shown in FIG. 3A, the front-rear direction of the left and right shoes 1, 1 is substantially perpendicular to the target direction. From this state, lean forward and stand on your toes without bending your knees. Then, bend your knees and make your toes stand in a stable center. Although this state is stable, the next operation can be started smoothly because the toes are standing.

  In the above address state, as shown in FIG. 3 (b), the dividing plate 12 of the rotating body is in a position that divides the internal space into two equal parts on the left and right, and in this position, the compression state of the left and right resilient members 13 is equal, This is a neutral state where no rotational force (resistance) is generated.

  From the above address state, the club is lifted while rotating to the right without twisting the body. Then, as shown in FIG. 4 (a), the left and right shoes 1, 1 rotate around the base of the big toe and turn to the right. At this time, the shoe sole 2 is actually rotating, but the rotating body 6 constituting the rotating mechanism 4 is relatively rotated. And as shown in FIG.4 (b) in the position which the rotary body 6 rotated relatively 90 degree | times, the right elastic member 13 reaches the compression limit, and rotation stops. This position is the end point of the backswing and the start point of follow-through.

From the back swing state, the club is lowered while rotating to the left without twisting, and the swing is started. Then, it passes through the address state, hits the ball at this point, and continues to rotate and lifts the club to follow-through. In this follow-through state, as shown in FIG. 5 (a), the left and right shoes 1, 1 rotate around the base of the big toe and turn to the left. Then, as shown in FIG. 5B, the left elastic member 13 reaches the compression limit at a position where the rotating body 6 is relatively rotated 90 degrees to the left, and the rotation stops. This position is the end point of follow-through.
