JP 10-277192 A

However, in Patent Document 1, the posture and head height of the golfer are fixed and the knee stretch is corrected, so that the lower body corrects the waist and legs, and the upper body corrects the vertical position of the head. It is not designed to correct shoulder movement.
Furthermore, in golf swings, it is important that the lower body (waist) rotation and the upper body (shoulder) vertical rotation operate in a coordinated manner, but such a coordinated operation is not corrected.

  The present invention has been made in view of the problems of the prior art described above, and its purpose is to acquire an appropriate swing form in the business zone in which the shoulder rotates smoothly along the stance as the waist rotates. An object of the present invention is to provide a golf swing correction device that can be used.

  In order to achieve the above object, in the first aspect of the golf swing correction apparatus, a flat base plate having a predetermined size on which a golfer can take a basic posture corresponding to an address, and a predetermined upper surface of the base plate are provided. A pulley mounted at a position via a tension coil spring and a single rope hung around the pulley are provided. The base plate is formed in a predetermined size that allows the golfer to take a basic posture corresponding to the address with respect to the virtual ball position, which is the pulley attachment position.

  (Operation) The golf swing correction device is used in a form in which a golfer rides on a base plate placed on, for example, a floor or the ground indoors and outdoors, and the weight of the golfer acts on the base plate.

  Specifically, on the base plate, the golfer grasps the predetermined positions on both ends of the rope hung around the pulley with the left and right hands, and the right and left legs are positioned so that the attachment position of the pulley to the base plate is directly facing the virtual ball position. The basic posture corresponding to the golf address is completed by determining the position, that is, the stance, and tilting slightly forward. In the basic posture corresponding to this address, adjust the position of the hand holding the rope so that both shoulders, both arms and the rope form an approximately isosceles triangle with the pulley at the apex, and the rope hung around the pulley is It is desirable to be straight with respect to the arm and pulled to some extent.

  From the basic posture corresponding to this address, the left and right shoulders and pulleys always form a triangle by bending and stretching the left and right arms while maintaining the tension of the rope within the business zone without breaking the posture. In other words, in other words, a half-swing compatible operation is performed in which the shoulders are vertically rotated along the stance direction in accordance with the rotation of the waist so as not to break the triangle having the shoulders and the pulleys as vertices. At this time, the center of gravity, which was near the center of the stance in the width direction of the stance in the basic posture, moves between the left and right hip joints by a half-swing compatible operation, but the golfer moves against the stationary pulley attachment position (virtual ball position). As long as the posture does not collapse, the golfer's head position hardly moves in any of the forward / backward, left / right and up / down directions.

  In this half-swing compatible operation, whether or not the waist and shoulders move properly in the half-swing compatible operation including the impact zone depends on whether the shoulder is rotated vertically along the stance and the center of gravity moves between the left and right hip joints. The golfer himself can determine.

  Also, in the business zone, the left and right shoulders and pulleys always form a triangle, and the half-swing where the shoulders rotate longitudinally along the stance direction as the hips rotate and the center of gravity moves between the left and right hip joints. When performing the corresponding operation, an inertial force resulting from the rotation of the waist and the vertical rotation of the shoulder acts as a tensile force on the pulley via the rope. Alternatively, even when the golfer's forward leaning posture collapses during the half-swing compatible operation, the inertial force resulting from the body's stretching action acts as a tensile force on the pulley via the rope.

  If the pulley is directly attached to the base plate, the tensile force acting on the pulley via the rope acts as a load on the golfer's body (waist, shoulders, and arms) and acts on this pulley. If the pulling force is large, the golfer's body may be damaged. However, in the first aspect, since the pulley is attached to the base plate via the tension coil spring, if a large tensile force acts on the pulley via the rope, the tension coil interposed between the pulley and the base plate. Since the spring is extended and the tensile force acting on the rope is reduced, the load acting on the golfer's body is also reduced. In other words, the tension coil spring has a buffering action to relieve the load acting on the golfer's body.

  Further, in a second aspect of the golf swing correcting device, in the first aspect, the base plate swings around a pivot shaft that connects the overlapped one end sides and can be freely opened and closed. A pair of left and right foot mounting plates having a predetermined width and a predetermined length for mounting the foot, and the other end side of the foot mounting plate is separated by a predetermined distance between the pair of left and right foot mounting plates A stance width adjusting mechanism for fixing and holding the pulley is provided, and the pulley is attached in the vicinity of the pivot shaft on the superimposed foot-placement plate on the upper surface side.

  (Operation) In the second aspect, the pair of left and right foot placement plates are swung around the pivot shaft and the other end side is opened at a predetermined angle, and the other end side of the foot placement plate is formed by the stance width adjusting mechanism. They are used after being fixedly held in a form separated from each other by a predetermined distance (a predetermined distance corresponding to the stance width of the basic posture of the golfer).

In particular, since the base plate is composed of a pair of left and right foot placement plates that swing around the pivot shaft, the weight is lighter than the base plate of the first aspect. When not used as a swing correction device, the pair of left and right foot placement plates are swung around the pivot axis and the other ends are closed, that is, the foot placement plates are folded into a compact form. Can be stored or carried.
Further, in the third aspect of the golf swing correction apparatus, a compact flat base plate that can carry at least one leg of an assistant, and a pulley that is attached to a predetermined position on the upper surface of the base plate via a tension coil spring, And a single rope hung around the pulley.

  (Operation) In the first and second embodiments described above, a golfer rides on a base plate placed on the floor or ground, for example, indoors and outdoors, and the weight of the golfer acts on the base plate. That is, the base plate is fixedly held to the floor or the ground by the golfer's own weight on the base plate.

  On the other hand, in the third aspect, since the golfer is used not in a room or on a base plate placed on the floor or the ground, for example, but in a position facing the base plate, the golfer performs a half-swing compatible operation. When it repeats, the force which moves or floats a baseplate with respect to a floor or the ground acts via a pulley. Therefore, it is necessary for an assistant to continue to press the base plate against the floor or the ground so that the base plate does not move or float with respect to the floor or the ground.

In other words, with the assistant stepping on the base plate with his / her foot against the floor or ground, the golfer grasps the predetermined position on both ends of the rope hung around the pulley with his left and right hands, and attaches the pulley to the base plate. The positions of the left and right feet, that is, the stances are determined so as to face each other as a virtual ball position, and the basic posture corresponding to the golf address is completed by slightly tilting forward.
Thereafter, as in the case of the first mode, the golfer bends the left and right arms from the basic posture corresponding to the address, while maintaining the tension of the rope within the business zone without losing the posture. Stretch out so that the shoulders and pulleys on the left and right always form a triangle, in other words, keep the shoulders along the stance direction as the hips rotate so as not to break the triangle with the shoulders and pulleys at the top. Operates for half-swing that rotates vertically. At this time, the center of gravity, which was near the center of the stance in the width direction of the stance in the basic posture, moves between the left and right hip joints by a half-swing compatible operation, but the golfer moves against the stationary pulley attachment position (virtual ball position). As long as the posture does not collapse, the golfer's head position hardly moves in any of the forward / backward, left / right and up / down directions.

The golfer himself / herself can determine whether or not the hips and shoulders are suitable for the half-swing compatible operation including the impact zone, depending on whether or not the shoulder is vertically rotated along the stance and the center of gravity is moving between the left and right hip joints.
The details of the golfer's half-swing compatible operation and the buffering action of the tension coil spring interposed between the pulley and the base plate are the same as in the case of the first aspect, and therefore redundant description thereof is omitted.

  Further, the base plate is compact enough to allow at least one leg of an assistant to be put on it, and is small in size, so it is convenient to carry and does not depend on the place where the golf swing correction device is used.

  Moreover, in the 4th aspect of the golf swing correction | amendment apparatus, in the 3rd aspect mentioned above, the to-be-latched part latched by the pile driven into the ground was provided in the said baseplate, It is characterized by the above-mentioned.

  (Operation) The pile driven into the ground hooks the hooked portion of the base plate, and the base plate is fixed and held so as not to move or float with respect to the floor or the ground. Accordingly, the stepping force on the base plate required by the assistant is reduced, and the golf swing correction device can be used by the golfer alone without any assistance from the assistant. Further, the pile can be driven into the ground using, for example, a hammer or a mallet, and after using the golf swing correction device, the pile can be extracted from the ground by lifting the base plate.

  Further, in a fifth aspect of the golf swing correction apparatus according to any one of the first to fourth aspects, the base plate side is disposed on the other end side of the tension coil spring having one end side connected to the pulley. A hook / engagement release hook is provided to form a pulley / spring unit, and the pulley / spring unit is detachably attached to the base plate. It is characterized by that.

  (Operation) If the engagement of the hook on the pulley / spring unit side with the hook engaged portion on the base plate side is released, the pulley / spring unit can be easily detached from the base plate. For example, in a caddy bag configured so that an umbrella can be carried, a hole for inserting an umbrella tip exposed on a side surface below the caddy bag is used as a hook engaged portion. That is, if the pulley / spring unit is attached to the umbrella insertion hole under the caddy back via a hook and the caddy is held so as not to move, for example, it can be used as a golf swing correction device. it can.

  Alternatively, the intersection of the horizontal frame and the vertical frame below the rear part of the caddy back loading cart is used as a hook engaged portion. That is, the pulley can be used as a golf swing correction device by attaching a pulley / spring unit via a hook at the intersection of the horizontal frame and the vertical frame below the caddy back loading cart when stopped.

  Further, in a sixth aspect of the golf swing correction apparatus, in the aspect according to any one of the first to fifth aspects, at least three of the bottom surfaces of the base plate can absorb unevenness of a region where the base plate is placed. The protrusion is provided.

  (Effect) Even if the place where the base plate is placed is on the ground where the earth and sand are exposed or on the turf grass in the course, the protrusion provided on the bottom surface of the base plate absorbs the difference in unevenness on the placement surface. It is held in a stable form with respect to the mounting surface.

  In particular, the rough and fairways in the course are inclined and not flat, but the protrusions enter the rough or fairway ground and prevent the base plate from sliding relative to the placement surface. In contrast, the base plate is held in a stable form.

  Further, in the seventh aspect of the golf swing correction device, a pulley in which a disk-shaped rotating wheel that is a pulley body is supported by a frame, a hook that is integrally attached to the pulley frame via a tension coil spring, And a single rope that hangs around the disk-shaped rotating wheel.

  (Operation) For example, in a caddy bag configured to carry an umbrella, a hook is secured to the hole for inserting the tip of the umbrella exposed on the side surface below the caddy bag, and a pulley, a tension coil spring, and a hook are used. The constructed golf swing correction device can be used as a golf swing correction device by attaching the golf swing correction device to the umbrella insertion hole of the caddy bag and holding the caddy so that the caddy does not move.

  Alternatively, a golf swing correction device comprising a pulley, a tension coil spring, and a hook is secured to a caddy back when the vehicle is stopped by hooking a hook at the intersection of the horizontal frame and the vertical frame below the rear of the caddy back loading cart. It can be used as a golf swing correction device by attaching it to the intersection of the horizontal frame and the vertical frame below the rear of the loading cart.

  In addition, the golfer's half-swing compatible operation and the buffering action of the tension coil spring interposed between the pulley and the hook when used as a golf swing correction device are the same as those in the first and third aspects. Therefore, the duplicate description is omitted.

  In the seventh aspect, compared with the first to sixth aspects described above, since the base plate is not provided, the device structure is simple, light and compact, and is more convenient to carry. In particular, it can be used as a golf swing correction device anytime and anywhere as long as there is an immovable place where a hook can be hooked.

  Further, in an eighth aspect of the golf swing correction apparatus, in the aspect described in any one of the first to seventh aspects, the spring constant of the tension coil spring is a beginner based on a maximum value corresponding to the expert specification. It is characterized by being set to become smaller as the specification.

  (Operation) Beginners with unstable swings tend to greatly change the tensile force acting on the rope during the half swing compatible operation using the golf swing correction device. The spring constant (spring hardness) is set so as to become smaller for beginners, with the maximum value corresponding to an advanced person as a reference.

  Specifically, it is assumed that an advanced user who has a stable swing has a substantially constant tensile force acting on the rope during the half-swing compatible operation, that is, does not change significantly. On the other hand, for beginners, it is assumed that the tensile force acting on the rope during the half-swing compatible operation changes greatly because the swing is not stable.

  Therefore, in the golf swing correction device, a tension coil spring having a spring constant suitable for golf proficiency and a golfer's needs is mounted.

  Specifically, the golf swing straightening device for advanced users is equipped with a basic, hard (large spring constant) tension coil spring that focuses on swing correction rather than reducing the load on the golfer's body. Yes. On the other hand, beginner-specific golf swing correction devices are equipped with a soft (small spring constant) tension coil spring, and focus is placed on reducing the load on the golfer's body rather than correcting the swing.

  As is clear from the above description, according to the present invention, the shoulders are vertically rotated along the stance by expanding and contracting the arms according to the rotation of the hips so as not to break the triangle with the left and right shoulders and the pulley at the top. By repeating the half-swing compatible operation of moving the center of gravity between the left and right hip joints, it is possible to acquire an appropriate form in the business zone without any cooperation.

  In addition, since the load acting on the golfer's body through the rope when the half-swing compatible operation is repeated is reduced by the buffering action of the tension coil spring, there is no risk of damaging the golfer's body.

  According to the second aspect, the pair of left and right foot placement plates constituting the base plate is lightweight, and when folded, it becomes a compact size, which is convenient for storage and carrying.

  According to the third aspect, in order to avoid breaking the triangle with the left and right shoulders and the pulley at the apex, the arms are extended and contracted according to the rotation of the waist, and the shoulders are vertically rotated along the stance between the left and right hip joints By repeating the half-swing compatible movement that moves the center of gravity, the appropriate form in the business zone can be worn with the assistance of the assistant.

In addition, since the load acting on the golfer's body through the rope when the half-swing compatible operation is repeated is reduced by the buffering action of the tension coil spring, there is no risk of damaging the golfer's body.
Further, since the base plate is very compact, it is easy to carry and can be used in a narrow place as required.

  According to the 4th aspect, even if it is a case where there is no assistant, it can be used only by a golfer.

  According to the fifth aspect, the pulley / spring unit removed from the base plate can be used with the pulley / spring unit attached to the base plate. Can be attached and used at the intersection of the horizontal frame and vertical frame below the rear of the caddy bag loading cart, making it easier to carry only the pulley / spring unit and rope except the base plate It is easy to use as a device.

  According to the sixth aspect, since the base plate is stabilized with respect to the mounting surface by the protrusion provided on the bottom surface of the base plate, the base plate can be used in places other than the flat floor surface indoors and outdoors. In particular, the golf swing correction device can be used not only on rough courses and fairways in the course, but also in soft places such as sandy ground where the surface is not flat.

  According to the seventh aspect, the golf swing straightening device can be used anytime and anywhere as long as it is a part that can be engaged with the hook of the pulley / spring unit and can be held so as not to move. Excellent.

  According to the eighth aspect, it is possible to provide a golf swing correction device that meets the needs of all golfers having different proficiency levels from advanced to beginners.

FIG. 2 is a front view showing a use state of the golf swing correcting device, wherein (a) shows a basic posture corresponding to a golfer's address, and (b) shows a takeback-supporting operation and a back when the golfer raises his right hand to the level of the right waist. The side half-swing compatible operation is shown, and (c) shows the follow side half-swing compatible operation in which the golfer raises his left hand to the height of the left waist. It is a disassembled perspective view of the golf swing correction apparatus which concerns on a 2nd Example. It is sectional drawing of the connection part of a left-right paired leg mounting plate which comprises a base plate. It is a top view at the time of use of the golf swing correction apparatus. It is a perspective view of the golf swing correction apparatus which concerns on a 3rd Example. It is a top view which shows the use condition of the golf swing correction apparatus. It is a perspective view of the golf swing correction apparatus which concerns on a 4th Example.

  Hereinafter, embodiments of the present invention will be described based on examples.

  FIG. 1 is a perspective view of the golf swing correcting apparatus according to the first embodiment, and FIG. 2 is a view showing a state in which the golf swing correcting apparatus is used.

  In these drawings, the golf swing correcting device 1A is used in a form in which a golfer rides on a base plate 10A placed on the floor or the ground, for example, and the weight of the golf player acts on the base plate 10A. In the figure, a state in which the base plate 10A is placed on the ground 8 where the outdoor soil is exposed is shown.

  That is, the golf swing correcting device 1A includes a flat base plate 10A formed in a predetermined size on which a golfer can take a basic posture corresponding to an address, and a tension coil spring at a predetermined position on the upper surface of the base plate 10A. The pulley 20 is attached via 30 and the single rope 40 is wound around the pulley 20. Specifically, the base plate 10A has a predetermined size that allows the golfer to take a basic posture corresponding to the address with respect to the virtual ball position that is the pulley 20 attachment position, for example, the front-rear width a is 60 cm and the left-right width b is 80 cm. , Plywood with a certain amount of weight (wooden board), which has a thickness of about 2cm, and is durable and does not damage or deform when the golfer moves his body ).

  Also, metal spike-like projections 12 are provided at the four corners of the back surface of the base plate 10A, so that the base plate 10A is stable even if the ground surface 8 has some irregularities. The protrusion 12 has a structure in which a male screw portion is provided on the proximal end side of the sharp spike main body 12a, and the protrusion 12 is fixed to the base plate 10A by screwing the male screw portion to the embedded nut 12b in the base plate 10A. Has been.

  Specifically, even if the place where the base plate 10A is placed is on the ground where the earth and sand are exposed or on the turf grass in the course, the protrusion 12 provided on the bottom surface of the base plate 10A absorbs the unevenness difference on the placement surface. The base plate 10A is held in a stable form with respect to the placement surface. In particular, the rough or fairway in the course is inclined and not flat, but the protrusion 12A is prevented from entering the ground of the rough or fairway, and the base plate 10A is prevented from sliding with respect to the mounting surface. The base plate 10A is held in a stable form with respect to the surface. Note that the protrusion 12 is not necessary when the base plate 10A is placed on a flat floor surface in the room.

  Further, a stance mark 14 indicating a position where the golfer stands is printed near the front side of the base plate 10 </ b> A substantially in the left-right direction, but the stance mark 14 is not always necessary. That is, the stance mark 14 merely indicates a general position in the basic posture corresponding to the address, and it is not necessary to match the stance mark 14. Of course, the distance from the ball to the stance position becomes shorter as the golf club to be used becomes shorter, as well as the width of the stance varies depending on the golfer. 1A can deal with swing correction according to all clubs used from approach shots to driver shots.

  Further, on the upper surface side of the base plate 10A, near the side edge portion extending to the left and right of the base plate 10A facing the stance mark 14, a metal fastener 16 for hooking the pulley 20 is projected. Yes. In the fastener 16, a semicircular arc-shaped retaining ring 16b projects vertically from a rectangular plate 16a that is screwed (16c) to the base plate 10A.

  The pulley 20 has a structure in which a disk-shaped rotating wheel 24, which is a pulley body, is rotatably supported by a U-shaped frame 22. A retaining ring 26 is relatively rotated on the U-shaped horizontal bar-shaped portion 22 a of the frame 22. The springs 30 are freely engaged, and a tension coil spring 30 is interposed between the retaining ring 26 and the fastener 16. That is, one end of the tension coil spring 30 is connected to the retaining ring 26 of the frame 22 on the pulley 20 side, and the other end is connected to the retaining ring 16b of the fastener 16 fixed to the base plate 10A. Is attached to the base plate 10 </ b> A via the tension coil spring 30.

  The pulley 20 is made of metal in consideration of durability, but when used as the correction device 1A, as shown in FIG. 2, the pulley 20 is slightly lifted upward by a rope 40 wound around the disk-shaped rotating wheel 24. Since it is held in a tensioned state, it is desirable that it is somewhat compact and does not become too heavy. Further, as will be described later, the pulley 20 is desirably compact from the image that both shoulders S1, S2, both arms A1, A2, and the rope 40 form a triangle having the pulley 20 as a vertex.

  Further, the rope 40 is engaged with the disk-shaped rotating wheel 24 of the pulley 20 so that the movement (running) of the rope 40 hung around the disk-shaped rotating wheel 24 of the pulley 20 and the rotation of the disk-shaped rotating wheel 24 are linked. For example, natural fibers such as cotton and hemp and synthetic fibers such as polyester and nylon are twisted to form one piece.

  The material of the rope 40 may be either natural fiber or synthetic fiber, but considering the adhesiveness with the disc-shaped rotating wheel 24 that is a pulley body, being difficult to slip by hand, light weight, etc. It is desirable to be composed of natural fibers. Although natural fibers are clearly inferior in tensile strength to synthetic fibers, natural fibers are desirable because the tensile strength of natural fibers is sufficient for use as a golf swing straightening device.

Hereinafter, the usage method of the golf swing correction apparatus 1A will be described based on FIGS. 2 (a), 2 (b), and 2 (c).
First, the golfer grasps the predetermined position on both ends of the rope 40 hung around the pulley 20 on the base plate 10A with his / her left and right hands so that the attachment position of the pulley 20 to the base plate 10A faces the virtual ball position. By determining the positions of the left and right feet, that is, the stance, and tilting slightly forward, the basic posture corresponding to the address of the golf swing is completed, with the center of gravity near the center of the stance in the width direction. Note that, since the stance mark 14 is present on the base plate 10A, the golfer can easily take the basic posture corresponding to the address on the base plate 10A.

  In the basic posture corresponding to this address, as shown in FIG. 2 (a), the ropes so that both shoulders S1, S2, both arms A1, A2 and the rope 40 form an approximately isosceles triangle having the pulley 20 as a vertex. The rope 40 hung around the pulley 20 (the disk-shaped rotating wheel 24) is adjusted straightly with respect to both arms A1 and A2 by slightly adjusting the position of the hands H1 and H2 that grip the arm 40. To do.

  From the basic posture corresponding to this address, the left and right arms A1, A2 are bent and stretched while maintaining the tension of the rope 40 within the business zone without breaking the previous posture, and the left and right shoulders S1, S2 In order to keep the pulley 20 constantly forming a triangle, a half-swing compatible operation is performed in which the shoulders S1 and S2 are vertically rotated along the stance direction L in accordance with the rotation of the waist. At this time, the center of gravity, which was near the center of the stance in the width direction of the stance in the basic posture, moves between the left and right hip joints by a half-swing compatible operation, but with respect to the stationary pulley 20 attachment position (virtual ball position). As long as the golfer's posture is not lost, the golfer's head moves little in any of the front, back, left, and right directions.

  Specifically, from the basic posture shown in FIG. 2 (a), the right hand H2 is pulled up to the level of the right waist while lowering the left arm A1 and bending the right elbow while the left arm A1 is lowered, and the left shoulder S1 is moved in the stance direction L. "Takeback compatible operation" in which both shoulders S1 and S2 are longitudinally rotated along the stance direction L to the halfway back so that the center of gravity moves onto the right hip joint (see FIG. 2 (b)) Next, in accordance with the rotation around the left of the waist, while stretching the right elbow, lowering the right hand H2 and bending the extending left elbow, raise the left hand H1 to the height of the left waist and move the right shoulder S2 in the stance direction. L is pushed forward to the left of L, and both shoulders S1 and S2 are vertically rotated along the stance direction L to the middle of follow after passing the impact zone, and the center of gravity moves onto the left hip joint. Operation "to (see FIG. 2 (c)) performed. After this, in accordance with the rotation of the waist around the right, while stretching the left elbow, lowering the left hand H1, bending the right elbow, pulling the right hand H2 up to the height of the right waist, and pushing the left shoulder S1 to the right rear in the stance direction L Thus, “back side half swing compatible operation” (see FIG. 2 (b)) in which both shoulders S 1 and S 2 are vertically rotated along the stance direction L to the half way back to move the center of gravity onto the right hip joint. The movement of the lower half (waist) and upper half (shoulder) of the golfer in the business zone is corrected by repeating the “following half-swing compatible operation” (see FIG. 2C).

  In particular, when the left and right arms A1, A2 are expanded and contracted while bending the elbows according to the rotation of the hips so that the triangles with the left and right shoulders S1, S2 and the pulley 20 as vertices are not broken, the shoulders S1, S2 are in the stance direction. Depending on whether or not the center of gravity moves on the right or left hip joint by longitudinally rotating along L, whether or not the waist and shoulders S1 and S2 move in the business zone including the impact zone can be determined by the golfer himself.

  Further, in this embodiment, on the base plate 10A, the “back half-swing compatible operation” shown in FIG. 2B and the “follow half-swing compatible operation” shown in FIG. Again, especially when shifting (switching) from “back-side half-swing compatible operation” to “follow-side half-swing compatible operation” or from “follow-side half-swing compatible operation” to “back-side half-swing compatible operation” At the time of switching (switching), inertial force resulting from the rotation of the waist, the vertical rotation of the shoulder, and the movement of the center of gravity acts on the pulley 20 via the rope 40 as a tensile force. That is, the rope 40 is pulled against the pulley 20 with an unexpected force. Further, even when the golfer's forward leaning posture collapses during the half-swing compatible operation, the force resulting from the rising of the body acts as a tensile force on the pulley 20 via the rope 40, that is, the rope 40 against the pulley 20. Will be pulled with unexpected force.

  If the pulley 20 is directly attached to the base plate 10 </ b> A without the tension coil spring 30, a large tensile force acting on the pulley 20 (an unexpected force that pulls the rope 40 against the pulley 20). It acts as a load on the golfer's body (waist, shoulders, and arms) and may cause injury.

  However, in this embodiment, since the pulley 20 is attached to the base plate 10A via the tension coil spring 30, if a tensile force more than necessary acts on the pulley 20 via the rope 40, that is, the golfer moves the rope. When pulling 40 with a force more than necessary, the tension coil spring 30 interposed between the pulley 20 and the base plate 10A extends, and the tensile force acting on the rope 40 is reduced, so that the load acting on the golfer's body. Is also reduced.

  Therefore, even if the golfer continues to use the golf swing correcting device 1A for a long time, the golfer can reduce the load acting on the body through the rope 40 by the buffering action of the tension coil spring 30. There is little possibility to hurt.

  As described above, the tension coil spring 30 is used to reduce a load that may act on the golfer's body through the rope 40 during use of the golf swing correction apparatus 1A. If the spring 30 is too large, the buffering action of the spring 30 is not sufficiently exhibited. Conversely, if the spring 30 is too soft, the movement of the golfer's lower body (waist) and upper body (shoulder) cannot be corrected sufficiently. For this reason, it is desirable that the hardness (spring constant) of the tension coil spring 30 is set in accordance with the proficiency level and needs of the golfer who uses the golf swing correction apparatus 1A.

  That is, an advanced player who has a stable swing is assumed to have a substantially constant tensile force acting on the rope 40 during the half-swing compatible operation. Therefore, by adopting the tension coil spring 30a having a large spring constant, Emphasis should be placed on correcting the movement of the lower body (waist) and upper body (shoulder) rather than reducing the load on the body. On the other hand, a beginner is assumed that the tensile force acting on the rope 40 during the half-swing compatible operation greatly changes as the swing is not stable. Therefore, by adopting the tension coil spring 30c having a small spring constant, the golfer It is desirable to focus on reducing the load on the body rather than correcting the movement of the lower body (waist) and upper body (shoulder).

Therefore, the golf swing correction device 1A has three types of specifications for advanced, intermediate, and beginners, which are equipped with tension coil springs 30a, 30b, and 30c having different spring constants, in order to meet the needs of golfers. It is prepared.
Specifically, in the advanced specification, a basic tension coil spring 30a (which has a large spring constant) is attached, and emphasis is placed on correcting the swing rather than reducing the load on the golfer's body. On the other hand, in the beginner specifications, a tension coil spring 30c having a softness (small spring constant) is attached, and emphasis is placed on reducing the load on the golfer's body rather than correcting the swing. In the intermediate specification, the tension coil spring 30b having the intermediate hardness (spring constant) between the tension coil springs 30a and 30b is mounted, and emphasis is placed on both the correction of the swing and the reduction of the load on the golfer's body. It is left.
