Description

  The present invention relates to a golf practice tool, and more particularly to a practice tool or a training tool suitable for performing a correct stroke for putting and a correct approach swing.

  Conventionally, in golf putting and approach, it is generally desirable to perform strokes and swings without breaking the pentagon formed by the gripping part of both hands holding the putter and club, both arms, and both shoulders. For this reason, various training tools or training tools have been proposed to assist golfers in practicing such strokes and swings.

  For example, in Japanese Patent Publication No. 7-507953 (Patent Document 1), a golf putting training tool in which semicircular members are attached to both ends of a long shaft so as to open outward, respectively. In this case, when practicing the putting stroke, both arms of the golfer (user) are used in a state of being accommodated in each semicircular member. It has been shown that by practicing the putting stroke, the golfer's arm and shoulder muscles can be trained.

  However, in the golf putting training tool proposed in Patent Document 1, only the user's arms are restricted during the putting stroke, and the user's hand part holding the putter can move freely. Therefore, during the putting stroke, the position of the user's hand gripping the putter is easy to move freely in the direction of the putting stroke or in a direction perpendicular to the putting stroke, and the putting operation using the wrist is thereby performed. The grip force that grips the putter is also likely to change, which makes it difficult to perform the putting stroke smoothly, and the practice of putting stroke in a state where the desired pentagon is maintained cannot be easily performed. is doing.

  In addition, in International Publication No. WO2002 / 055159 (Patent Document 2), a pentagonal arm device equipped with an arm pad and a putter or an iron golf club provided at the tip of the pentagonal shape are fixed. A stroke corrector with a golf club fixture has been proposed. And in such a stroke correction device, while holding and holding the arm of the practitioner (user) in the arm pad of the arm device, the golf club fixture is fixed with a putter or an iron club, It is said that the correct putting or approach can be acquired by practicing the putting or approach while the practitioner grips the fixed putter or iron.

  Thus, even in the stroke correcting device as proposed in Patent Document 2, the shaft of the putter or the iron golf club is fixed by the golf club fixing device provided at the tip of the arm device. Therefore, the practitioner can practice putting and approach without gripping the grip of the fixed putter or iron golf club with the required force, so that any gripping force can be achieved. It would be difficult for the practitioner to learn whether the target putting or approach could be performed effectively. In addition, even when the grip of the putter or iron golf club is strongly squeezed, the effect of the putting and approach stroke based on such gripping is small because the putter and iron golf club are fixed, As a result, it is difficult to know the proper gripping force during the stroke of the putting and approach, and there is a possibility that this may delay the progress of the practitioner's putting and approach. is there.

  Here, the present invention has been made in the background of such circumstances, and the problem to be solved is to break the pentagon formed by the user's shoulders, arms, and hands (gripping). In addition, as the body rotates, the stroke or swing can be effectively assisted so that the integral stroke or swing can be performed, and the user holds the grip of the golf club with an appropriate gripping force. Thus, it is an object of the present invention to provide a golf practice tool that can correctly practice strokes and approaches.

  In the present invention, in order to solve the problems as described above, a golf club to be practiced is placed at the lower end portion of the longitudinal longitudinal main body portion having rigidity, which is positioned in a vertically inclined state. A shaft holding portion on which the shaft is mounted and supported, while the upper end of the longitudinal body is positioned so as to cross the front chest of the user. Further, arm locking portions that are fixed to the user's upper arm portion are provided at both ends of the lateral body portion, respectively, and elastic by the tightening force between the user's arms. The gist of the golf practice tool is characterized in that an elastically deformable portion that can be bent is provided in at least one of the lateral body portion and the arm locking portion.

  According to a desirable aspect of the golf practice tool according to the present invention, the shaft holding portion is configured in an L-shape having rigidity composed of a vertical portion and a horizontal portion, and on the free end side of the vertical portion, While being attached to the lower end portion of the longitudinal body portion, the horizontal portion is arranged so as to extend in the same direction as the transverse body portion so that the shaft of the golf club can be placed thereon. Yes.

  Moreover, in another desirable aspect of the golf practice tool according to the present invention, a rotation mechanism is provided in which the horizontal portion of the shaft holding portion is rotated around the vertical portion, and the horizontal portion is rotated 180 °. And can be arranged so as to extend to the opposite side with respect to the longitudinal main body.

  Further, in the present invention, advantageously, the longitudinal body portion has a length adjusting mechanism capable of adjusting the longitudinal length thereof, and the transverse body portion is laterally arranged. A length adjusting mechanism capable of adjusting the length is provided.

  And according to one of the desirable aspects of the golf practice tool according to this invention, the said horizontal direction main-body part has a curved part so that the said user's front chest part may be met.

  According to another desirable aspect of the golf practice tool according to the present invention, the arm locking portions are configured to include L-shaped portions respectively provided at both ends of the lateral body portion, and The elastically deformable portion can be deformed by positioning the L-shaped portion so as to be sandwiched between both sides of the user and fastening both arms together.

  Furthermore, according to another desirable aspect of the present invention, each of the portions of the lateral body portion located on both sides of the attachment portion of the longitudinal body portion is provided with the elastic deformation portions, respectively, It is desirable that the arm locking portion is made of a material having rigidity so as not to be substantially deformed.

  In addition, according to a different preferred embodiment of the golf practice tool according to the present invention, the longitudinal body part, the transverse body part, the shaft holding part, and the arm locking part are constituted by a rod or a pipe.

  As described above, in the golf practice tool according to the present invention, the upper arm portion of the user is attached to the arm locking portions provided at both ends of the lateral body portion positioned so as to cross the front chest of the user. From the place where at least one of the lateral body portion and the arm locking portion can be elastically bent and deformed by the tightening force between both arms of the user. If the user tightens both sides to generate a required tightening force to cause bending deformation, the user's arms receive the reaction force against such elastic bending deformation. And by continuously applying a force against such reaction force with both arms of the user, it is possible to effectively suppress or prevent the user from applying a large force to both hands holding the grip of the golf club. Therefore, it is possible to play golf with an appropriate gripping force while maintaining the shape of the pentagon formed by the user's shoulders, arms, and hands (gripping) without breaking the pentagon. By holding the grip of the club, you can effectively perform putting strokes and approach swings.

  Moreover, in the golf practice tool according to the present invention, when used, the practice is performed on the shaft holding portion provided at the lower end portion of the longitudinal longitudinal main body portion having rigidity, which is positioned in an inclined state in the vertical direction. In a state where the shaft of the target golf club is placed and held, the stroke or swing is assisted by moving the golf club by rotating the body by grasping the grip of the golf club with both hands. However, stroke practice and swing practice will be performed, but at that time, the golf club is simply placed on the shaft holding part and supported, and never fixed. This is different from the conventional case of simply holding or supporting the grip of a golf club. If the golf club is not gripped with a certain degree of gripping force, the golf club cannot perform strokes or swings. Therefore, the required force for gripping the golf club during putting or approach is required. It is possible to perform effective stroke practice and swing practice in order to learn the strength and shape.

  Hereinafter, in order to clarify the configuration of the present invention more specifically, a representative embodiment of a golf practice tool according to the present invention will be described in detail with reference to the drawings.

  First, FIG. 1 shows an example of a golf practice tool according to the present invention as a front view in an upright configuration, and FIGS. 2 (a) and 2 (b) show a plan view and a bottom view, respectively. 3A and 3B are a left side view and a right side view, respectively. In addition, FIG. 4 shows a perspective view of such a golf practice tool laid sideways.

  And in those figures, 10 is a longitudinal longitudinal main body having rigidity, and here it is configured using a pipe made of hard resin or metal, and when used as a golf practice tool The structure does not substantially deform. Further, an adjusting screw cylinder 12 as a length adjusting mechanism is disposed at an intermediate portion of the vertical body 10, and the pipes 10 a and 10 b on both sides thereof are connected by the adjusting screw cylinder 12. As a result, the vertical body portion 10 is configured as a whole. Here, the adjusting screw cylinder 12 is assembled with the pipes 10a and 10b screwed in opposite directions to the opening portions at both ends, as shown in FIG. In the state, the pipes 10a and 10b can be made to approach each other in the axial direction by rotating in one direction around the axis of the adjustment screw cylinder 12, while By rotating in the opposite direction, the pipes 10a and 10b can be separated from each other in the axial direction, whereby the longitudinal length of the longitudinal body portion 10 is adjusted to the user. It can be adjusted.

  A connecting pipe 16 extends in a direction perpendicular to the pipe 10b and toward the user via an L-shaped joint 14 at the end of the pipe 10b on the lower side of the longitudinal main body 10. In addition, a rigid L-shaped pipe 18 having a horizontal portion 18a and a vertical portion 18b is fitted to the connecting pipe 16 at the vertical portion 18b. . When a torsional force having a predetermined magnitude is applied to the connection pipe 16, the L-shaped pipe 18 can be rotated around the axis of the connection pipe 16, and the horizontal portion 18a is formed as shown in FIG. In FIG. 2, it is rotated by 180 ° and can be arranged so as to extend to the side opposite to the longitudinal main body 10 (to the left in FIG. 1). Further, as will be described later, a golf club shaft (including a grip head side portion) to be practiced is placed on the horizontal portion 18a of the L-shaped pipe 18 so as to be supported. It is. The vertical portion 18b of the L-shaped pipe 18 can prevent free movement of the shaft toward the rear side in the swing direction (left side in FIG. 1), and can prevent the wrist from being bent during back swing. On the other hand, at the time of follow swing, a force that pushes the shaft forward acts as the body rotates, thereby assisting the follow swing in the correct direction. Therefore, the shaft holding part 20 is comprised from these L-shaped couplings 14, the connection pipe 16, and the L-shaped pipe 18 here.

  On the other hand, the upper end portion of the pipe 10 a located at the upper part of the vertical body portion 10 is fitted and attached to the leg portion of the T-shaped joint 22, and both ends of the head of the T-shaped joint 22 are opened. The resin pipes 24a and 24b having predetermined lengths that can be elastically deformed are detachably fitted to the respective parts, and the T-shaped joint 22 and the two resin pipes 24a and 24b will be described later. In addition, a longitudinal transverse body 26 is constructed which is positioned so as to cross the front chest of the user. Therefore, the two resin pipes 24a and 24b are formed of a resin material having a relatively soft elasticity (restorability), and when a tightening force between both arms of the user is applied, as will be described later. In addition, it is configured so as to be able to bend elastically, thereby forming an elastic deformation portion. In this way, in the lateral body portion 26 in which the longitudinal body portion 10 is attached to the intermediate portion via the T-shaped joint 22, the extending direction of the resin pipes 24a and 24b constituting the longitudinal body portion 10 is vertical. It is comprised so that it may correspond substantially with the direction where the horizontal part 18a of the L-shaped pipe 18 in the shaft holding part 20 provided in the lower end part of the direction main-body part 10 is extended.

  Furthermore, arm locking portions 28 and 28 each having a large L shape are disposed at both ends of the lateral body portion 26, and the end portions on the respective attachment sides are further bent by 90 °. Thus, it is configured so as to exhibit a crank shape as a whole, and the arm locking portions 28 and 28 are rotatable and detachable with respect to the ends of the resin pipes 24a and 24b at the bent portions. It is fitted and attached. The arm locking portions 28 and 28 are locked to the upper arm portion of the user, in other words, positioned so as to be sandwiched between both sides of the user and engaged with the upper arm portion including the elbow portion. In this case, even when such a tightening force is applied, the arm locking portions 28, 28 are arranged so that the arm locking portions 28, 28 can be applied with each other. It is made of a hard material having rigidity so as not to be substantially deformed, so that such a tightening force can effectively act on the lateral body portion 26. . Further, as shown in FIG. 3 and FIG. 4, the main body in the longitudinal direction is operated by a rotation operation with respect to the resin pipes 24a and 24b so that the arm locking portions 28 and 28 can be effectively sandwiched between both sides of the user. The unit 10 can be arranged to be inclined with a predetermined inclination angle.

  Then, for example, when practicing a putting stroke using the golf practice tool having such a configuration, first, as shown in FIGS. 6 to 9, the lateral body 26 is placed on the front chest of the user. In a state of being positioned so as to cross the arm, the L-shaped portions of the arm locking portions 28, 28 on both sides are positioned so as to be sandwiched between both sides of the user and locked to the upper arm portion including the elbow portion. On the other hand, the grip 32 of the putter 30 is correctly gripped by the user with both hands. Further, the shaft 34 of the putter 30 is placed on the horizontal portion 18a of the L-shaped pipe 18 in the shaft holding portion 20 provided at the lower end portion of the longitudinal main body portion 10 which is positioned in a vertically inclined state, While the user is supported, the user can tighten the arms to each other, so that the clamping force between the arms is applied to the lateral body portion 26 from the arm locking portion 28, thereby The resin pipes 24a and 24b serving as elastic deformation portions in the direction main body portion 26 are allowed to bend slightly elastically. By doing so, it becomes difficult for the user to grip the grip 32 of the putter 30 strongly, so that the grip 32 is gripped with an appropriate gripping force. In the state, the user rotates the body without breaking the pentagon formed by gripping both shoulders, both arms, and both hands, and accordingly, moves the putter 30 supported by the golf exerciser together with the golf practice tool. As a result, repeated putting practice is performed.

  Accordingly, in putting stroke practice using the golf practice tool as described above, tightening via the L-shaped portions of the arm locking portions 28 and 28 locked so as to be sandwiched between both sides of the user. Due to the action, the resin pipes 24a and 24b, which are elastically deforming portions of the lateral body portion 26, are elastically slightly bent and deformed, and the reaction force accompanying the bending deformation is caused by both of the users. Since it acts on the arm, the gripping force of the grip 32 of the putter 30 can be effectively suppressed or restricted, making it difficult to grip the grip 32 strongly. Then, by this, the user is reminded to grasp the grip 32 with an appropriate gripping force, and the putter 30 moves together with the golf practice tool by rotating the body in such a gripping state. Thus, the training of the putting stroke can be advantageously performed.

  In addition, in the illustrated golf practice tool, the shaft 34 of the putter 30 (including the head side portion of the grip 32) is an L-shaped pipe in the shaft holding portion 20 provided at the lower end portion of the longitudinal body portion 10. It is placed on the horizontal part 18a of the 18 and supported so that it is not fixed as in the prior art. In the right-handed user, the putter 30 is pushed out by the movement of the vertical body portion 10 as the body rotates during the follow swing, This allows the user to remember the proper gripping force and to wear the correct stroke.

  That is, the integrally constructed lateral body portion 26 and arm locking portions 28 and 28 at both ends of the golf practice tool are held by the user's body, while the lateral body portion 26 Since the shaft holding portion 20 is provided at the lower end portion of the longitudinal main body portion 10 integrally attached to the intermediate portion, the putting stroke of the putter 30 is difficult unless the user rotates the body. As the body rotates, the longitudinal main body 10 is also rotated about the body, and is thus constituted by the user's shoulders, arms and hands. If the putting stroke is not made without breaking the pentagon, the ball cannot be hit. During the follow swing, the putter 30 is pushed by the vertical body 10. By doing so, it will move smoothly forward without breaking such a pentagonal shape, so by practicing the putting stroke in such a form, the correct grip and the correct stroke are achieved, The user can easily understand and learn.

  The shaft 34 placed and supported on the horizontal portion 18a of the L-shaped pipe 18 in the shaft holding portion 20 is also moved backward in the putting stroke in contact with the vertical portion 18b during backswing. Since it can be prevented by this, it is not possible to put using the wrist, and for that reason, the correction of the putting stroke using the user's wrist can be performed advantageously. is there.

  1 to 5 show a golf practice tool according to the present invention as a right-handed user's follow swing (stroke) correction or practice tool. In order to use for (stroke) correction / practice, in FIG. 1, the horizontal portion 18 a of the L-shaped pipe 18 in the shaft holding portion 20 may be disposed on the left side of the longitudinal body portion 10. As a result, during back swing (stroke), the shaft 34 of the putter 30 is placed on the horizontal portion 18a as the body rotates, and is pushed backward and moved smoothly. Thus, the smooth movement of the backswing is correctly understood by the user. Here, since the L-shaped pipe 18 is fitted around the axis of the connecting pipe 16 so as to be rotatable at least 180 °, the L-shaped pipe 18 is rotated 180 ° around the axis of the connecting pipe 16. By doing so, the horizontal portion 18a is easily located on the side opposite to the longitudinal body portion 10, that is, on the left side in FIG. 1, and extends in the same direction as the lateral body portion 26. , Can be placed.

  As described above, the horizontal portion 18a of the L-shaped pipe 18 in the shaft holding portion 20 has a longitudinal main body portion depending on the purpose of the user's swing (stroke) correction or practice, and for each swing (stroke) symptom. 10 will be placed on the right or left side, but in the case of a left-handed user, the swing (stroke) will be completely opposite to that of a right-handed user. The arrangement of the horizontal portion 18a in the case of the user is completely opposite to that of the right-handed user described above. For this reason, it is desirable that the horizontal portion 18 a (L-shaped pipe 18) be rotated around the axis of the connection pipe 16 as in the illustrated specific example.

  Further, in the illustrated golf practice tool, the vertical body 10 is provided with an adjusting screw cylinder 12, and the length suitable for the user is selected by adjusting the vertical length according to the rotation direction. However, it is also possible to provide a similar length adjusting mechanism for the lateral body 26 so that the lateral length can be adjusted. However, since the resin pipes 24a and 24b are detachable from the T-shaped joint 22 and the arm locking portion 28, respectively, the resin pipes 24a and 24b can be attached according to the width of the chest of the user. By replacing the resin pipes prepared in advance with different lengths, it is possible to obtain the transverse body 26 having a length suitable for the user.

  Furthermore, the arm locking portions 28 and 28 that are locked to the upper arm portion of the user have rigidity that does not substantially deform when the user applies a tightening force between the arms. Although it is comprised by the pipe which consists of a material which has, with resin pipe 24a, 24b in the horizontal direction main-body part 26, or it replaces with it, it is from the comparatively soft resin material similar to such resin pipe 24a, 24b. It is also possible to use an elastically deformable resin pipe that is provided with an elastically deformable portion.

  In addition, as is apparent from the structure shown in FIGS. 3 and 4, even if the arm locking portions 28, 28 and the longitudinal main body 10 are at an angle, the body shape such as the height and the length of the arm and the use thereof are used. It is desirable that it can be adjusted as appropriate depending on the person's posture (posture) and the like. For this reason, in the illustrated specific example, the arm locking portion is provided with respect to the resin pipes 24a and 24b. It is configured to be rotatable around an axis. Accordingly, it is possible to employ an arrangement structure of the arm locking portions 28 and 28 that best suits the user.

  By the way, the golf practice tool according to the present invention is rotated by the rotation of the user's body without breaking the pentagon formed by gripping the user's shoulders, arms and hands, and the user grips. Because it is possible to hit a ball with a golf club that has been hit, swing that does not break such a pentagon is required, practice of approach of a short distance of up to about 2,30 yards, such as pitch end run and running The golf practice tool of the above example can also be used as it is for practice of the approach swing. However, especially in such a short distance approach swing, since the hand first posture is emphasized, as shown in FIG. This T-shaped joint 22 ′ is constructed in a state that is inclined at an angle such that the desired hand-fast angle can be provided, rather than at a right angle as shown in FIG. By adjusting the lengths of the resin pipes 24a ′ and 24b ′ so that they are positioned in a state of being biased to the arm locking portion 28 on one side, and thus, a golf practice tool suitable for approach swing Is desirable. Moreover, in this approach swing, unlike the putting stroke, there is a problem of bending of the wrist during follow swing, so the position of the horizontal portion 18a of the L-shaped pipe 18 in the shaft holding portion 20 is the longitudinal body. The part 10 is arranged opposite to that in FIG.

  In the golf practice tool shown in FIG. 10, it is used for right-handed use. To make it left-handed, the T-shaped joint 22 ′ is rotated 180 °. The left and right resin pipes 24a 'and 24b' are arranged in the left and right direction so that the legs are inclined in the direction opposite to that shown in FIG. The resin pipe 24b ′ having a short length is disposed, and the resin pipe 24a ′ having a long length is disposed on the right side, and is attached to and detached from the T-shaped joint 22 ′ and the left and right arm locking portions 28 and 28, respectively. By making the fitting possible, a left-handed golf practice tool in which the longitudinal body portion 10 is inclined in the direction opposite to that in FIG. 10 is configured.

  In the present invention, a structure in which the inclination angle of the leg portion with respect to the head in such a T-shaped joint 22 'can be changed as appropriate can be employed. Thus, there is an advantage that the angle can be arbitrarily adjusted according to the body shape of the user.

  Furthermore, it is also possible to dispose the leg portion of the T-shaped joint 22 ′ at a right angle with respect to the head as in the specific example shown in FIG. 1. In that case, it is also effective to place such right-angled T-shaped joints in a biased manner as shown in FIG.

  The representative embodiments of the present invention have been described in detail above, but these are merely examples, and the present invention is not limited to any specific description according to such embodiments. It should be understood that the interpretation is not intended.

  For example, in the embodiment described above, the horizontal body 26, specifically, the resin pipes 24a and 24b are all used in a straight shape, but as shown in FIG. In particular, it is also advantageous that the resin pipes 24a and 24b are respectively bent so that the resin pipes 24a and 24b are shaped along the outer contour line so as to be along the front chest 40 of the user.

  In the illustrated embodiment, the L-shaped pipe 18 in the shaft holding portion 20 is integrally formed of the horizontal portion 18a and the vertical portion 18b. Instead, the horizontal portion 18a and the vertical portion are formed. It is possible to make the horizontal part 18a detachable from the vertical part 18b while the horizontal part 18a is separated from the vertical part 18b. Further, a mounting part for the horizontal part 18a is provided at the axially symmetrical position of the vertical part 18b. Thus, by allowing the horizontal portion 18a to be attached around the vertical portion 18b with a phase difference of 180 °, it can be used not only for right-handed use but also for left-handed use.

  By the way, as the length adjusting mechanism, it is possible to adjust the length by using various known structures in addition to the adjusting screw cylinder 12 having the structure as shown in FIG. Any of them can be adopted. Of course, the pipes 10a, 10b; 24a, 24b constituting the vertical body 10 and the horizontal body 26 are detachably assembled, but pipes having different lengths are prepared. It is possible to adjust the overall length of each of the main body portions 10 and 26 by appropriately selecting and replacing them, and it is the simplest and easiest to do so. By adopting a mechanism that can adjust the respective fitting depths, the overall length of each of the main body portions 10 and 26 can be adjusted, and further, the end portions of the pipes can be screwed into other members and joints. It is also possible to adjust the overall length of each main body 10, 26 by adjusting the amount of screwing. It is.

  Furthermore, in the golf practice tool according to the present invention, a portion that touches the user's arm or side, for example, in the illustrated embodiment, the outer surfaces of the crank-shaped arm locking portions 28 and 28 are urethane foamed. It is also possible to advantageously employ covering with a material having cushioning properties such as a body to soften the feeling during use.

  In addition, in the illustrated golf practice tool, the longitudinal body portion 10, the transverse body portion 26, the shaft holding portion 20, and the arm locking portions 28, 28 are all configured by pipes, thereby reducing weight. However, some or all of them can also be constituted by rods, and can also be constituted by a combination of pipes and rods. Furthermore, as a material of these members, in addition to those made of resin or metal, it can also be made of bamboo or wood, and if a metal is used as a material, a light metal such as aluminum or titanium, Although it will be used advantageously, it is also possible to use a material such as stainless steel which does not easily generate rust.

  Furthermore, in the golf practice tool according to the present invention, it is possible to easily carry it by configuring it in a form that can be removed (disassembled) without fixing each member constituting the golf practice tool. It can have.

  In the present specification, the term “upper arm” includes the elbow, and the shaft of the golf club placed and supported on the shaft holding portion 20 (horizontal portion 18a) It should be understood that the golf club (30) is used including the grip (32) portion located on the tip side, in other words, on the head side relative to the gripping portion.
