Description

  The present invention relates to a golf swing practice device that makes it easy for a user to learn the entire golf swing.

  A golf swing does not produce good results unless it satisfies several conditions in a fast motion. In order to solve these problems, an L-shaped arm that rotates at a position where the rotation axis is set to an extended position of the swing center point of the user is provided, and the tip of the L-shaped arm is coaxial. An apparatus has been developed that includes a means for applying a load during a downswing to a main shaft of an apparatus provided with a rotating means and having a holding means that can rotate back and forth across the club shaft near the tip of the club grip. Patent Document 1).

  When the practitioner swings the apparatus by himself, a load is applied during the downswing. By repeating this operation, the swinging force can be acquired and a stable swing form can be obtained.

  The effect is recognized in that this device can always swing in the same trajectory. However, although there is a high possibility of problems in the swing plane and ergonomics, it is an advantage that a load is applied during this downswing to acquire muscle strength.

It is also true that the swing-pivot swing training device enables operations that are impossible or difficult, and swing muscle strength can also be obtained by applying a load. In addition, there is an advantage that an effect that a swing motion can be quickly learned can be expected.
JP 2000-325523 A

  Golf swings are most rationally impacted by a plane that matches the club's own lie angle (hereinafter referred to as the swing plane). However, from an ergonomic point of view, if you trace the swing plane, the left arm is disturbed by the body and stops near the bottom of the chest, resulting in an insufficient swing, so the action of raising both arms straight above this position Join. The reason is that if you hold the club with both hands, you can only use the arm itself by bending one arm because of the triangle formed by both shoulders and arms. In order to keep this triangle and move the arm effectively and use it for acceleration, if you have the same shape as the posture of the upper stage of kendo, you can hold the club with both hands and make a triangle, and you can move the arm widely and from the middle of the back swing This movement adds to the club's swing plane. Many golfers misunderstand that the position of the top arm is about the right shoulder and that the shaft tilts the ball toward the ball, tracing the correct swing plane. It is shifted to. If you're crazy like this, you won't get a good result if you swing around the ball.

  Furthermore, recent swings have been changed to swings that raise the hand position and obtain effective acceleration of both arms. If swinging as it is, the result becomes worse because the correct swing plane cannot be obtained. The world's proficient golfers get good results regardless of whether their arms are up or down, instead of swinging on the plane from the top, instead of swinging the hand position and club position off the swing plane at the beginning of the downswing This is because it gradually returns to the swing plane. This is because the club swing plane P shown in FIG. 1 is shifted from the one-dot chain line to the top of P1 and moved to the top, and in the case of a downswing, it is returned to the swing plane in the same way toward the impact.

  In addition, there are changes that occur during the swing in terms of arc size. This also happens for ergonomic reasons. When the back swing enters from the address and the swing plane P comes off and the cock starts from the position of the chest, the arc drawn by the grip destination shaft portion must be close to the body and the arc must be reduced, and the shoulder returns to the down And the downward movement of the arm (the action of returning to the swing plane P) is added, the position of the hand approaches the body and the wheel becomes even smaller. In a bad movement, casting is performed and the position where the right arm extends is away from the body, and the contact point of the arm of the simulated club is further away from the body, so that the ring becomes large and cannot be placed on the swing plane P. This can be said to be a drawback in that the ring through which the casting passes and the ring of the down swing using the swing axis swing training device are similar. There is no change in the arc in the conventional rotating shaft swing practice device.

  An object of the present invention is to solve the above-mentioned problems, and when a swing is strengthened through a load on a rotating shaft that can only be achieved by a conventional rotating shaft swing training device, basically a flat surface is traced. A golf swing practice device that solves the problem of difference and can learn a swing that is close to reality.

  The present invention relates to the ergonomics that occurs in an actual swing while passing the face direction, the incident angle, the trajectory, etc. under good conditions while tracing the motion before and after the impact of the club satisfying the key of a good swing, that is, by tracing the lie angle plane. To solve the contradiction between the upper movement and the swing axis swing training device on the device, the arm is equipped with the movement of the arm up and down, elbow break, arm twist, wrist cock and hinge, etc. It is reproduced by combining movement, sliding, expansion and contraction, etc., and the user eliminates the gap with the actual swing motion and has a device obtained by overcoming the load braking provided on the rotating shaft.

  That is, a golf swing practice device according to the present invention includes an arm whose tip is pivotally supported on a pivot shaft so as to be rotatable along a swing plane, and a grip provided at the tip of the arm, The grip is attached so as to be slidable along the axis of the arm, rotatable about the axis of the arm, further rotatable in the axial direction of the arm, and rotatable about the axis of the grip. It is characterized by.

  By using the golf swing practice device of the present invention, it is possible to acquire a habit of satisfying the essentials of a good swing and performing a swing with high reproducibility in a short period of time even if a user's favorite swing is added. Furthermore, for fast muscles that increase the speed of the body, repeated high-load braking has the advantage of increasing the possibility of speeding up the swing.

  The golf swing practice device according to the present invention includes an arm whose tip is pivotally supported on a pivot shaft so as to be rotatable along the swing plane as described above, and a grip provided on the tip of the arm. The grip is slidable along the axis of the arm, rotatable about the axis of the arm, further rotatable in the axial direction of the arm, and rotatable about the axis of the grip. It is attached.

The arm case is connected to the rotation shaft, and is rotatable with the rotation of the rotation shaft. An arm is inserted into the arm case so as to be extendable and fixed. In one preferred form, the arm includes a fixed part parallel to the inclined surface, a swing part inclined at substantially the same angle in the opposite direction, and a connecting part for connecting the fixed part and the swing part. It has a nearly trapezoidal shape. Therefore, the tip of the swing part of the arm draws a swing plane trajectory as the pivot shaft rotates.

  In a preferred embodiment of the present invention, a sliding cylinder is provided at the tip of the swing part of the arm so as to be slidable and rotatable along the swing part of the arm. A grip is provided on the sliding cylinder. Thus, the grip is ensured to slide along the axis of the arm and can be rotated about the axis of the arm. In one form, the said grip is attached to the plane part provided in the said sliding cylinder via the grip support part, and the said support part is being fixed to the said plane part so that rotation is possible. This allows the grip to rotate about the axis of the grip. One end portion of the grip is pivotally connected to the grip support portion via a pivot shaft, thereby being pivotable in the axial direction of the arm.

  In a preferred form according to the present invention, the arm case into which the arm is inserted is provided with a long hole, while the arm fixing part is provided with a bolt, and by locking the bolt and the long hole of the fixing part, It is possible to change the total length of the arm.

  In another embodiment of the present invention, instead of the sliding cylinder, a fitting cylinder is provided in the arm connecting portion, and the swinging portion is inserted into the fitting cylinder so as to be slidable. Allows axial sliding. In one preferred embodiment, the grip has a structure in which the grip support portion is provided at the tip of the swing portion of the arm.

  In another preferred embodiment of the present invention, the cylindrical case is provided on the arm swing portion so as to be rotatable along the arm axis and slidable, and the rotatable portion protruding from the side of the cylindrical case protrudes. In addition, a grip is provided on the rotating portion so as to be rotatable about the axis of the grip. At this time, the grip passes through the rotating part and is attached to the rotating part via a spring.

  Examples will be described below, but the present invention is not limited thereto.

  FIG. 1 is a schematic view of an embodiment of a golf swing practice apparatus according to the present invention. As is clear from this figure, the golf swing practice apparatus according to the present invention is a support vertically installed on a support base 1. A column 2 is provided, and an arm control unit 3 slidable along the support column 2 is provided above the support column 2. The arm control unit 3 includes a control unit main body 31 having an inclined surface 311 on the practitioner side, and a support unit 32 that fixes the control unit main body 31 to the support pillar 3 so as to be slidable. Further, the support part 32 and the control part main body 31 are fixed via a rotation shaft 321 so that the control part main body 31 can be rotated about the rotation shaft 321. That is, the control unit main body 31 is slidable in the vertical direction of the support column 2 and is rotatable.

  An arm rotation shaft 33 penetrates and protrudes from the inside of the control unit main body 31 to the inclined surface 311. The arm rotation shaft 33 can brake the torque of rotation by a load braking device unit housed in the control unit main body 31. The load braking device section includes a one-way clutch 34 provided at the front end of the arm rotation shaft 33 in the control unit main body 31, a disk 35 provided on the one-way clutch 34, and a braking load section 36. The strength of braking is performed by means for controlling the strength of pressing the pad 37.

  The arm rotation shaft 33 is connected to an arm case 4 provided in parallel to the inclined surface 311, and the arm case 4 rotates as the arm rotation shaft 33 rotates. It has become. The arm 5 is inserted and fixed to the arm case 4 so that the length can be adjusted. Specifically, the overall length of the arm 5 can be controlled by a long hole 41 provided in the arm case 4 and a bolt 51 provided at one end of the arm 5.

  The arm 5 includes a fixed part 52 parallel to the inclined surface 311, a swing part 53 inclined at substantially the same angle in the opposite direction to the fixed part 52, and a connection part 54 connecting the fixed part 52 and the swing part 53. It has a basically trapezoidal shape. The other end 55 of the arm 5 is provided with a sliding cylinder 6 that can slide along the axis of the swing portion 53 of the arm 5, and the sliding cylinder 6 is provided at the tip of the arm 5. The stopper ring 57 provided on a predetermined portion of the swing portion 53 and the stopper ring 57 provided on a predetermined portion of the swing portion 53 can be slid (arrow A1). Further, as shown in FIG. 2, the sliding cylinder 6 is attached so as to be rotatable about the axis L1 of the arm 5 (see arrow A2).

  As shown in FIG. 2, the sliding cylinder 6 is provided with a flat surface portion 61, and a grip 7 is provided on the flat surface portion 61 via a grip support portion 8 rotatably provided on the flat surface portion 61. It is fixed. As shown in FIG. 3, one end 71 of the grip 7 is supported by a grip support 8 via a grip rotation shaft 81. For this reason, the grip 7 can be rotated in the direction of the axis L1 of the arm 5 by the grip rotation shaft 81 (see arrow A3). A grip stopper 82 is provided at the upper end portion of the grip support portion 8 so that the grip 7 does not rotate in the direction of the connecting portion 54 of the arm 5.

  The grip support portion 8 is attached to the flat surface portion 61 of the sliding cylinder 6 by the grip support portion rotation shaft 83 so as to be rotatable (arrow A4) as described above. For this reason, the grip support portion 8 is rotatable about the grip support portion rotation shaft 83, and therefore the grip 7 is also rotatable about the axis (L2) of the grip 7 (arrow A5). . The grip support portion 8 is provided with a locking claw 84 on the tip end side of the arm 5, and on the other hand, a stopper pin 85 that is movable on the arm connection portion 54 side of the flat surface portion 61 is provided. When the grip 7 rotates, the locking claw 84 comes into contact with the stopper pin 85 so that no further rotation occurs. The degree of rotation of the grip 7 can be controlled by moving the stopper pin 85 in a direction perpendicular to the axis L1.

  When practicing using such an apparatus, the axis L3 of the arm rotation shaft 33 is set in accordance with the swing plane P and the center point of the swing (near the practitioner's chest). Such setting is performed by rotating the control unit main body 31 about the rotation shaft 321 and sliding the support unit 32 about the support column 2.

  When the practitioner performs swing exercise, first, the grip 7 is gripped. At this time, since the grip 7 can be rotated in the direction of the axis L1 of the arm 5 by the grip rotation shaft 81, the grip 7 can be held at a desired angle with respect to the swing plane P. When the swing practice is started, the arm 5 and the arm case 4 rotate about the arm rotation shaft 33, and the distal end portion 55 of the swing portion 53 of the arm 5 rotates along the swing plane P. The arm of the practitioner is raised from the middle of the backswing and lifts off the swing plane P. The sliding cylinder 6 slides along the axis L1 of the arm 5 and further rotates about the axis L1 of the arm 5. . At this time, the grip 7 is also rotated about the axis L2 when the grip support 8 is rotated about the grip support rotation shaft 83, and the arm can be raised smoothly. For this reason, the sliding cylinder 6 is disengaged from the swing plane P (the sliding cylinder 6 is separated from the distal end portion 55 of the arm 5), and the path of the plane P1 is drawn. The trajectory of the plane P1 is controlled by the sliding amount of the sliding cylinder 6. This sliding amount can be controlled by the stopper ring 57. By changing the position of the stopper ring 57, the trajectory of the plane P1 can be controlled. Further, as the top swing is approached, the direction of the left back turns about 90 degrees from the time of addressing and faces the arm rotation shaft 33. This rotation is also possible by the rotation of the grip 7. The stopper ring 57 controls the top position of the back swing.

  In addition, cocking starts gradually from the time when the aforementioned arm movement is applied. Since early cocking is an operation of raising the tip of the simulated club, it can be dealt with by sliding along the axis L1 of the arm 5 of the sliding cylinder 6 and rotating the arm rotating shaft 33. As the cock further advances, the grip end 72 of the grip 7 faces downward. In this process, the grip 7 rotates about the axis L2 (A5) and the arm 7 of the grip 7 rotates in the direction of the axis L1 (A3). Realize with.

  In the wrist cock operation, the arc drawn by the tip of the simulated club is gradually reduced, and the inner circle moves about 15 cm when the final arc is drawn. In this movement, the fixed portion 52 of the arm 5 inserted in the arm case 4 fixed to the arm rotating shaft 33 is positioned higher than the arm rotating shaft 33, and its own weight is added to slide inwardly. The bolt 51 provided in 52 slides the elongated hole 41 formed in the arm case 4 from one end and stops at the other end of the elongated hole 41.

  To enter the downswing and pass a good line, turn your shoulders and pull your arms down from the waist to the chest. With this operation, the arm case 4 in which the fixing portion 52 of the arm 5 is inserted is lowered to the vicinity of the swing plane P. At this time, the direction of the wrist cock and the left back is kept facing the arm rotation shaft 33 and the arm 5 Is lowered toward the retaining ring 56 of the front end portion 55.

  The preparation for drawing the trajectory of the swing plane P is now complete. Here, since the wrist cock is relatively maintained, the locking claw 84 of the grip support 8 is only slightly separated from the stopper pin 85, and the grip (shaft) 7 is also inclined to the arm 5 near the diagonal line. When the hand descends from this state to the waist level, the sliding cylinder 6 slides to the stop ring 56 and at the same time, the grip 7 rotates in the opposite direction, leaving the movement of tracing the swing plane P at the same time as the sliding. The cylinder slightly contacts the retaining ring 56. Turn the shoulder, swing out on the swing plane P, and the sliding cylinder 6 remains in contact with the retaining ring 56 until the hand reaches the level of the left waist and chest. After passing the position of the waist, the arm is naturally raised up and off the swing plane P and enters the finish.

  In the case of an impact, it is said that the driver should have a straight line from the left shoulder to the head when viewed from the front, but when viewed from the back of the flying ball line, it is bent into a character with the grip position as the boundary correct. In some cases, it is better for the hand to be in the flying direction than the head when viewed from the front. In the case of an iron, in many cases, it is better to have an impact with the hand coming out in the flying direction than the head. These movements also have the advantage that they can be freely experienced by the practitioner's consciousness because the sliding cylinder 6 can rotate the arm 5. This consciousness is too early for general swings to be recognized, so it is difficult to remember.

  In the back swing, the arm 5, the sliding cylinder 6, the grip support portion 8, the grip rotation shaft 81, the weight of the grip 7, and the like are loaded, and the top swing is reached. As means for applying a load from the downswing to the finish, a one-way clutch 34 provided at the tip of the arm rotation shaft 33 in the control unit main body 31 in the inward direction, a disk 35 provided on the one-way clutch 34, and a braking load part 36 are provided. I have. The strength of braking is performed by means for controlling the strength of pressing the pad 37. As another rotation control means, a gear is provided on the arm rotation shaft 33, and the rotation is changed to a vertical movement by a rack gear, and an air cylinder pump or a hydraulic cylinder pump can be used.

  FIG. 4 is a view showing an embodiment of the table 2 of the present invention. As is clear from this drawing, in this embodiment, the sliding cylinder 6 for sliding the arm 5 is not provided. Instead, the swing portion 53 of the arm 5 is inserted into a fitting cylinder 58 provided in the connection portion 54, and the swing portion 53 slides in the fitting cylinder 58, whereby the arm 5 of the grip 5. The action of moving along the axis of the swing part 53 is ensured.

  5 (a) and 5 (b), a structure in which a sliding cylinder 9 that can slide along the axis of the arm 5 is provided for the arm 5 and a rotating portion 91 that rotates to the side of the sliding cylinder 9 is provided. Indicates. Further, the grip 7 is passed through the turning portion 91 and a spring 92 is fixed between the grip tip portion 71 and the turning portion 91 to control and hold the expansion and contraction and rotation of the grip 7. 2, 4, and 5, the grip angle can be directed in all directions with respect to the axis of the arm tip, and by controlling each rotation and slide, both the motion control and the degree of freedom required for the swing are achieved. It is now possible to meet the incompatible conditions.
