Description

  The present invention relates to a golf swing and other equipment used for golf practice.

  One of the criteria for improving golf is whether the golfer can fly the golf ball at the intended distance in the intended direction using a golf club selected as appropriate. It is traditionally thought that attaching is important.

  A golf swing consists of an address posture, a grip mode, a body rotation, a wrist and arm turn, and the like, and so on. A series of operations from a backswing to a downswing and a follow swing is performed. It is ideal to be made along a virtual plane called a swing plane. It is extremely difficult to wear such an ideal swing through practice. For this reason, various instruments for swing practice have been proposed in the past (for example, see Patent Documents 1 to 4).

  A conventional swing practice device regulates the movement of a part of a golfer's body (for example, wrist) during a swing, and corrects the swing by repeated practice.

  By the way, as described above, the mechanism of the golf swing is complicated and its analysis is extremely difficult. Generally, a golf swing has a starboard turn centered on the right leg axis from an address state, an arm operation, a wrist operation and a chest operation performed simultaneously with the starboard turn (so-called back swing), and then switching to the reversing operation. (A so-called down swing), a left turn part around the left leg axis after impact, an arm action, a wrist action and a chest action which are performed simultaneously with the left turn part. In a golf swing, these operations are not performed sequentially but proceed simultaneously while being related to each other. Therefore, even if you repeat the practice of restricting the trajectory of a part of the swing exercise focusing on only the movement of the part of the body, the effect of the practice is difficult to obtain and the balance of the entire swing is lost. There is a risk that.

  The inventor of the present application studies the swing practice method, and in order to acquire a correct swing, the club head is carried along a predetermined virtual trajectory rather than correcting the body movement in accordance with a predetermined swing plane. As a result, it was learned that the practice of drawing an image of an ideal swing plane is effective.

  The present invention has been made based on such a background, and an object thereof is to provide a golf practice tool capable of effective swing practice and other practice.

  (1) A golf practice tool according to the present invention has an elongated rod-like main pillar, a leg that supports the main pillar, and an elongated straight rod connected to the main pillar via a connector. The connecting tool grips the first straight part that is fitted to the main pillar and is fixed at an arbitrary position of the main pillar, and the elongated straight bar, and the elongated straight bar extends in the longitudinal direction of the main pillar. And a second fixing portion that intersects at an arbitrary angle.

  In the present invention, the main pillar is supported by the leg portion. The main pillar can be supported in an arbitrary posture, but is typically supported in a posture along the vertical direction. The elongate straight bar is connected to the main pillar via the connector. Specifically, the connecting tool is fixed at an arbitrary position of the main pillar by the first fixing portion, and the elongated straight bar is gripped by the second fixing portion, whereby the main pillar is attached to the main pillar. Cross at an arbitrary angle. Accordingly, the elongated straight bar is disposed at an arbitrary height with respect to the practice ground at an arbitrary angle.

  (2) The leg may include a base and three support bars provided on the base. In that case, the base end of each support rod is rotatably connected to the base, and each support rod is bundled along the longitudinal direction, and the second posture is developed radially from the base. It is preferable that the posture can be changed between.

  In this configuration, the leg is configured as a tripod that can be folded. By changing the leg to the second posture, the main pillar can be stably supported. Further, when the leg is changed to the first posture, the main pillar, the elongated straight bar and the leg are arranged along the longitudinal direction of the main pillar, so that the golf practice tool can be easily stored in the caddy bag. Is done.

  (3) The first fixing portion is formed in an annular shape having an outer peripheral surface and an inner peripheral surface, and sandwiches the ring member with a ring member having a slit cut from the inner peripheral surface to the outer peripheral surface in the radial direction. And a pair of fastening plates erected on the outer peripheral surface so as to face each other, and a fastening member that engages with the pair of fastening plates and brings the pair of fastening plates close to or away from each other. .

  In this configuration, the elongated straight bar is inserted into the ring member, and is easily clamped and fixed by the pair of fastening pieces when the fastening member is operated.

  (4) The second fixing portion may have a holding block provided with a through hole. The inner surface shape of the through hole corresponds to the outer surface shape of the elongated straight rod, and the holding block and the elongated straight rod have a predetermined length so that the elongated straight rod is held by the holding block with a certain holding force. It is preferable that the fitting is performed by fitting tolerance.

  In this configuration, the elongate straight bar is simply held with a constant holding force simply by being inserted into the through hole of the holding section path section. Since the holding force is caused by the fit, the portion where the elongated straight bar is gripped by the holding block is easily changed. In other words, the holding block can hold an arbitrary position of the elongated straight bar.

  (5) The holding block according to any one of claims 1 to 4, wherein the holding block is rotatably provided on the first fixing portion.

  According to this structure, the angle which cross | intersects the said main pillar is changed easily and rapidly, when the said holding block rotates with respect to the said 1st fixing | fixed part.

  According to this invention, since the said elongate straight bar is arrange | positioned by arbitrary height and angle with respect to a practice ground, the said elongate straight bar is arrange | positioned in a required attitude | position according to a physique of a golfer. The golfer can practice swinging so as to carry the club head of the golf club along the elongated straight bar arranged as described above. The practice is effective as image training for forming a so-called ideal swing plane, and effective practice is possible.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings as appropriate.

  1 and 2 are external perspective views of a golf practice tool 10 according to an embodiment of the present invention. FIG. 1 shows a use state, and FIG. 2 shows a storage state.

  The golf practice tool 10 includes a tripod 11 (corresponding to “leg” described in claims), a main pillar 12, and a straight bar 13 (corresponding to “elongated straight bar” described in claims). And a connecting tool 14 for connecting the straight bar 13 to the main pillar 12. As will be described in detail later, this golf practice tool 10 is disposed in the vicinity of a golfer who performs swing practice, and is erected on a practice ground by a tripod 11.

  The golf practice tool 10 according to the present embodiment is characterized in that (a) the straight bar 13 is held at an arbitrary position and posture with respect to the main pillar 12, and the golfer can use this straight bar. Swing practice with 13 as a mark (see Fig. 1) and (b) The tripod 11 can be folded (see Fig. 2) and can be easily stored in a caddy bag It is.

  The tripod 11 includes a base block 15 (corresponding to a “base” described in claims), and three support rods 16 to 18 are attached thereto. In addition, as this tripod 11, what is marketed for cameras etc. can be employ | adopted. The support bar 16 has three blanks, and each blank is assembled in a nested manner. Thereby, the support bar 16 can expand and contract in the longitudinal direction. In this embodiment, the length of the support bar 16 is about 10 cm in the contracted state and about 25 cm in the extended state.

  The support bars 17 and 18 have the same structure as the support bar 16. Although not shown in detail, the base ends of the support rods 16 to 18 are rotatably connected to the base block 15 via hinges not shown. Thereby, each support rod 16-18 can change to the attitude | position (equivalent to the "2nd attitude | position" described in the claim) radially open from the base black 15 as FIG. 1 shows, Further, as shown in FIG. 2, the posture can be changed to a posture bundled along the longitudinal direction of the main pillar 12 (corresponding to a “first posture” described in the claims).

  In this embodiment, the main column 12 is composed of a resin cylindrical pipe. The color of the main pillar 12 is preferably a conspicuous color (for example, black). Specifically, the outer diameter of the main pillar 12 is set to about 12 mm to 20 mm, and the length of the main pillar 12 is set to about 80 cm to 120 cm. The main column 12 is preferably made of carbon fiber reinforced resin. The lower end of the main pillar 12 is fixed to the base block 15 of the tripod 11. The means for fixing the main pillar 12 is not particularly limited, and known means can be adopted.

  The main pillar 12 is not limited to the cylindrical pipe as described above, and may be any other as long as it can support the straight bar 13 at a predetermined height and at a predetermined inclination as described later. The shape may be made of other materials. However, when the main pillar 12 is formed of a cylindrical pipe made of resin, the golf practice tool 10 is reduced in weight, the manufacturing and assembling operations are easy, and the cost can be reduced.

  The straight bar 13 is also composed of a cylindrical pipe made of resin like the main pillar 12. Since the straight bar 13 functions as a landmark for the swing as will be described later, the color of the straight bar 13 is preferably conspicuous such as white. The outer diameter of the straight bar 13 is set to about 8 mm to 12 mm, and the length is set to about 80 cm to 120 cm. Since the straight bar 13 is held in a posture that protrudes from the main column 12 in a substantially horizontal direction as will be described later, weight reduction is required and high bending rigidity is required. For this reason, it is desirable that the straight bar 13 is formed of a carbon fiber reinforced resin.

  FIG. 3 is an enlarged view of the connector 14. FIG. 4 is an exploded perspective view of the connector 14.

  The connector 14 includes a first fixing part 19 and a second fixing part 20. The first fixing portion 19 positions the connector 14 at a desired position of the main pillar 12. The second fixing portion 20 is engaged with the first fixing portion 19 and holds the straight bar 13.

  The first fixing portion 19 includes a fitting member 21 and a fastening mechanism 22 that engages with the fitting member 21 and fastens the fitting member 21 to the main pillar 12 (“clamping member described in claims”). For example).

  In this embodiment, the fitting member 21 is made of a metal such as steel or an aluminum alloy. But the fitting member 21 may be comprised from resin and other materials. The fitting member 21 includes an annular ring portion 23 (corresponding to a “ring portion” recited in the claims), and fastening plates 24 and 25 provided on the ring portion 23. In the present embodiment, the ring 23 and the fastening plates 24 and 25 are integrally formed. However, these may be configured as separate members and fixed by known fixing means.

  The inner peripheral surface 26 of the ring portion 23 has a cylindrical shape and defines the inner diameter of the ring portion 23. The inner diameter of the ring part 23 corresponds to the outer diameter of the main pillar 12, and the main pillar 12 can be easily inserted into the ring part 23. A slit 27 is provided in the ring portion 23. The slit 27 is cut from the inner peripheral surface 26 of the ring portion 23 to the outer peripheral surface 28 in the radial direction.

  The fastening plates 24 and 25 are disposed so as to face each other with the slit 27 interposed therebetween. The fastening plates 24 and 25 are erected on the outer peripheral surface 28 of the ring portion 23. That is, the fastening plates 24 and 25 protrude outward in the radial direction of the ring portion 23, and a gap corresponding to the width dimension of the slit 27 is formed therebetween. This gap functions as a so-called fastening allowance, and when the fastening plates 24 and 25 come close to each other, the slit 27 becomes narrower and the inner diameter of the ring portion 23 becomes smaller. That is, the ring portion 23 fastens and fixes the main pillar 12. In addition, through holes 29 are provided in the fastening plates 24 and 25. The function of the through hole 29 will be described later.

  The fastening mechanism 22 includes a fastening bolt 30, an operation nut 31, and a coil spring 36 and a washer 37 interposed therebetween.

  The fastening bolt 30 is made of a metal such as steel or aluminum alloy in this embodiment. The tightening bolt 30 has a cylindrical head portion 32 and a shaft portion 33. A through hole 34 is provided in the head 32, and the through hole 34 penetrates the head 32 in the radial direction as shown in FIG. The inner diameter of the through hole 34 corresponds to the outer diameter of the straight bar 13. Further, the outer diameter of the shaft portion 33 corresponds to the inner diameter of the through hole 29 provided in the fastening plates 24 and 25, and the shaft portion 33 is inserted into the through hole 29. A male screw 35 is formed on the outer peripheral surface of the shaft portion 33. The male screw 35 is screwed with the operation nut 31.

  With the tightening bolt 30 inserted into the fitting member 21 from the tightening plate 24 side and passing through the tightening plate 24 and the tightening plate 25, the coil spring 36 and the washer 37 are arranged in order from the tightening plate 25 side. It is inserted into the part 33. Then, the operation nut 31 is engaged with the shaft portion 33. A female screw (not shown) is formed in the operation nut 31, and the female screw is screwed with the male screw 35. The operation nut 31 includes a handle 38, and the operation nut 31 is easily tightened to the tightening bolt 30 by operating the handle 38. When the operation nut 31 is rotated in the clockwise direction, the operation nut 31 is fastened to the tightening bolt 30 and the fastening plates 24 and 25 are brought close to each other. That is, the fitting member 21 fastens the main pillar 12. When the operation nut 31 is rotated counterclockwise, the operation nut 31 is loosened and the fastening plates 24 and 25 are separated from each other. In addition, since the coil spring 36 and the washer 37 are provided, loosening of the operation nut 31 is prevented.

  The second fixing portion 20 has a holding casing 39. The holding casing 39 and the head 32 of the tightening bolt 31 constitute the second fixing portion 20. That is, the head 32 of the fastening bolt 31 also serves as a part of the second fixing portion 20 (corresponding to a “holding block” described in the claims). As described above, the through hole 34 is provided in the head 32 of the fastening bolt 31. Specifically, a constant interference fit tolerance is set between the outer diameter of the straight bar 13 and the inner diameter of the through hole 34. For this reason, the straight bar 13 is pushed into the through hole 34, and as a result, a constant frictional force is generated between the straight bar 13 and the head 32. Therefore, in a state where the straight bar 13 is inserted into the through hole 34, the straight bar 13 is held by the fastening bolt 30 with a holding force corresponding to the friction force. When a constant external force that resists the frictional force is applied in the axial direction of the straight bar 13, the straight bar 13 can slide with respect to the tightening bolt 30.

  In this embodiment, the holding casing 39 is made of a metal such as steel or an aluminum alloy, and is formed in a cylindrical shape. The front end portion of the holding casing 39 is reduced in diameter, and an inclined surface 40 whose outer diameter gradually decreases is formed. The front end diameter of the holding casing 39 is smaller than the inner diameter of the through hole 29 provided in the tightening plate 25. Therefore, as shown in FIG. 4, when the holding casing 39 is pressed against the fastening plate 25, a part of the front end portion of the holding casing 39 is inserted into the fastening plate 25. In this state, the holding casing 39 can rotate around the axial direction (the direction indicated by the one-dot chain line in the drawing).

  A through hole 41 is provided in the holding casing 39. As shown in FIG. 4, the through-hole 41 penetrates the holding casing 39 in the radial direction (direction orthogonal to the axial direction). The inner diameter of the through hole 41 is the same as the through hole 34 provided in the head 32 of the fastening bolt 30. Although not shown in FIG. 4, the holding casing 39 is formed in a cylindrical shape. That is, a circular opening is provided at the rear end of the holding casing 39, and a cavity is formed in the holding casing 39 continuously with the opening. The inner diameter of the opening corresponds to the outer diameter of the head 32 of the fastening bolt 30. When the fastening bolt 30 is inserted into the holding casing 39, the shaft portion 33 penetrates the holding block 39, and the head portion 32 is received in the cavity. In this state, the through hole 34 provided in the head 32 and the through hole 41 provided in the holding block 39 are aligned, and the straight bar 13 is inserted into the through holes 41 and 34. Yes.

  That is, the holding casing 39 and the head 32 can be integrally rotated with respect to the fitting member 21 in a state where the head 32 of the tightening bolt 31 holds the straight rod 13. As shown in FIG. 1, the second fixing portion 20 can arrange the straight bar 13 at an arbitrary position with respect to the longitudinal direction of the main column 12 and intersect at an arbitrary angle.
