Description

Technical Field

[0001] The present invention relates to a swing training device that can be used for practicing swings such as golf swings, and more particularly to an inexpensive swing training device that can experience the deflection and return of the shaft of a golf club and an accurate swing trajectory on a plane and master them.

Background Art

[0002] Conventionally, various training devices have been used for practicing golf swings. For example, a rod-shaped golf swing training device imitating a golf club is known. By repeatedly performing a practice swing, the device enables a user to acquire an accurate swing form while improving swing speed and swing power.

[0003] For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-204845) discloses a golf swing training device having a rigid shaft portion with a grip portion as a gripping part on the surface, and a pendulum portion extending from the tip of the shaft portion and having flexibility and a restoring elasticity to a substantially straight state.

[0004] Further, Patent Document 2 (Japanese Patent Application Laid-Open No. 2013-70926) discloses a golf swing training device in which one-side grip is provided on one end side of a shaft, the other-side grip is provided on the other end side, and when the one-side grip portion is vibrated with the other-side grip portion fixed, the vibration frequency is defined as "F1 (cpm)", and when the other-side grip portion is vibrated with the one-side grip portion fixed, the vibration frequency is defined as "F2 (cpm)", and it is characterized in that "F1 < F2" and "F1 = 90 cpm to 220 cpm".

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the golf swing practice device of Patent Document 1 described above is, for example, as shown in FIG. 6 of Cited Document 1, intended to greatly bend the golf swing practice device during a swing, and is composed of a very soft elastic material. For this reason, the golf swing practice device only makes a shadow swing imitating a club or an iron and only slightly feels the swing sensation. It is difficult to experience the bending and return during a swing, and there is a risk that the swing trajectory will become erratic.

[0007] In addition, the golf swing practice device of Patent Document 2 described above has a shaft made of glass fiber. Since the bending during a swing is insufficient, it is difficult to acquire the correct impact zone by making a shadow swing, and it is difficult to experience the bending and return during a swing. Also, there is a problem that it is difficult to experience an accurate swing trajectory.

[0008] Therefore, the present invention has been made to address the above problems, and the problem to be solved is to be able to experience the bending and return of the shaft during a swing while acquiring the correct form of a swing such as a golf swing, and at the same time, to be able to experience the swing trajectory in a plane and acquire an accurate swing trajectory. An object of the present invention is to provide a swing practice device.

Means for Solving the Problems

[0009] In order to achieve the above object, the present inventor conducted intensive research on the shape, structure, material, specifications, etc. of the swing practice device. As a result, it was found that it is extremely effective to use a resin shaft having a specific shape, dimensions, and bending / return for experiencing the bending and return during a swing and the swing trajectory. The present invention has been achieved.

[0010] To solve the above problems, the present invention provides: a resin shaft, a grip attached to one end of the shaft, and a weight of 1 g to 100 g attached to the other end of the shaft, characterized by a swing training device.

[0011] In the swing training device of the present invention, it is preferable that the shaft has a thickness of 6.0 mm to 13.0 mm, and the overall length of the swing training device is 90 cm to 117 cm.

[0012] Also, in the swing training device of the present invention, it is preferable that the shaft is hollow.

[0013] Also, in the swing training device of the present invention, it is preferable that the shaft has flexibility such that one end can be bent to contact the other end.

[0014] Furthermore, in the swing training device of the present invention, it is preferable that the weight is cap-shaped and has an opening penetrating in a direction perpendicular to the longitudinal direction of the shaft. is preferable.

[0015] Furthermore, in the swing training device of the present invention, it is preferable that the distance (bending width) from the tip portion during bending to the perpendicular line of the shaft at rest is 70 to 100 cm.

Advantages of the Invention

[0016] The swing training device of the present invention is preferable because it allows the user to experience an appropriate bend and return of the shaft during swinging while acquiring the correct form of swinging such as a golf swing, and also allows the user to experience the repeated swing trajectory in a plane, enabling the user to accurately acquire a preferable swing trajectory.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, representative embodiments of the swing training device of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto. In the following description, the same or corresponding parts may be denoted by the same reference numerals, and duplicate descriptions may be omitted. In addition, since the drawings are for conceptually explaining the present invention, the dimensions and ratios of the components shown may be different from the actual ones in some cases.

[0019] FIG. 1 is a front view (a) and a side view (b) of a swing training device 1 according to an embodiment of the present invention. As shown in FIG. 1, the swing training device 1 has a shaft 2 and a grip 4, and the grip 4 is attached to one end of the shaft 2. Further, a weight 6 of 1 g to 100 g is attached to the other end of the shaft 2 opposite to the end to which the grip 4 is attached.

[0020] As a result of intensive research on the shape, structure, material, specifications, etc. of the swing training device, the inventor has found that a swing training device having such a specific configuration is extremely effective for experiencing the swing trajectory because the deflection and return during swinging are appropriate.

[0021] First, various materials can be used for the shaft 2 as long as they are within the range where the effects of the present invention can be achieved. For example, it can be made of a resin such as polypropylene or polycarbonate. In this embodiment, it has a hollow pipe shape. Also, the thickness (outer diameter) is preferably, for example, 6.0 mm to 13.0 mm. Further, the inner diameter of the shaft 2 having a hollow pipe shape is preferably, for example, 2.0 to 4.5 mm.

[0022] And in this embodiment, it is preferable that the shaft 2 has flexibility such that one end can be bent to contact the other end. That is, when one end and the other end of the shaft 2 are respectively grasped with the right hand and the left hand and bent, it is preferable that the shaft 2 has flexibility such that even when one end and the other end of the shaft 2 come into contact, the shaft 2 bends beautifully without being damaged such as breaking.

[0023] Also, the overall length of the swing training device 1 including the shaft 2 is not particularly limited as long as it is within the range where the effects of the present invention can be achieved. For example, the overall length can be 90 cm to 120 cm, preferably 90 cm to 115 cm. Within these ranges, an appropriate length of the golf swing training device that can achieve the effects of the present invention can be selected according to the physique and height of the user, and for example, it can be suitably stored in a golf bag.

[0024] The manufacturing method of the shaft 2 is not particularly limited, and various conventionally known manufacturing methods can be used as long as the effects of the present invention are not impaired. From the viewpoints of productivity and product price, an extrusion molding method or an injection molding method can be used.

[0025] Next, the grip 4 attached to one end of the shaft 2 of the swing practice device 1 may be a grip used for various sports, but a golf grip is preferable. The shaft 2 may be inserted into the concave portion of the grip 4 and connected with an adhesive, double-sided tape, or the like.

[0026] The grip 4 is formed using an elastic material, and it is preferable that a fine uneven pattern or the like that also serves as an anti-slip is formed on the outer peripheral surface of the grip 4, for example, by knurling. Also, although the inner diameter of the grip 4 is constant, it is preferable that the outer diameter gradually increases as it approaches one end side (grip end side) of the grip 4.

[0027] As the elastic material of the grip 4, for example, rubber, synthetic resin elastomer, etc. are preferably used, but it is not limited to these, and any material that enables insert molding and has elasticity and flexibility suitable for the grip can be used.

[0028] The weight 6 attached to the other end of the shaft 2 only needs to have a weight that can impart appropriate deflection and return during the swing of the swing practice device 1, for example, it may be 1 g to 100 g, and in order to more surely obtain the effect of the present invention, it is particularly preferably 20 g to 50 g. The weight 6 of the present embodiment is in a cap shape and is externally inserted into the shaft 2 and connected, for example, with an adhesive or double-sided tape as shown in FIGS. 1(a) and 2.

[0029] According to the swing practice device 1 including the shaft 2, the grip 4, and the weight 6 configured as described above, ideal weight and mechanical characteristics (such as deflection and return and trajectory during swing) as a swing practice device can be exhibited. Therefore, for example, as shown in FIG. 3, during the swing practice using the swing practice device 1, the deflection and return of the swing practice device 1 are continuous (repeated) so as to transition in the direction of the arrow, and as shown in FIG. 4, during the swing practice using the swing practice device 1, the swing practice device 1 bends and returns while tracing on the virtual plane P so that the swing trajectory does not wobble, and the practice of capturing the swing trajectory can be repeated, which is suitable for acquiring the swing trajectory.

[0030] Here, it is preferable that the weight 6 has an opening 6a penetrating in a direction perpendicular to the longitudinal direction of the shaft 2. Due to the presence of this opening 6a, as shown in FIGS. 2 and 3, during swing practice, if the flexure and return of the swing practice device 1 are continuous (repeated) and the swing trajectory can be accurately captured on the plane P repeatedly, since the wind passes through the opening 6a and makes a "whoosh, whoosh" sound, it is useful for confirming whether the swing trajectory is correct and is suitable for its acquisition.

[0031] Also, as a member constituting the opening 6a, a flute member 8 having the structure shown in the side view and front view of FIGS. 2(c) and 2(d) may be incorporated in the weight 6. Due to the incorporation of this flute member 8, during swing practice, if the flexure and return of the swing practice device 1 are continuous (repeated) and the swing trajectory can be accurately captured on the plane repeatedly, since the wind passes through the opening 6a and the flute member 8 surely makes a sound, it is useful for confirming whether the swing trajectory is correct and is more suitable for its acquisition.

[0032] Note that the shape of the weight 6 is not particularly limited as long as the effects of the present invention are not impaired and the ease of swinging of the swing practice device 1 is not hindered. For example, various shapes such as spherical, disc-shaped, plate-shaped, and star-shaped can be adopted.

[0033] Next, FIG. 5 shows a schematic diagram for explaining the flexure width X during swinging in the swing practice device 1 of the present embodiment. As shown in FIG. 5, in the swing practice device 1 of the present embodiment, the distance (flexure width X) from the tip portion at the time of flexure P1 to the shaft at rest P2 of the perpendicular line during swinging is 70 cm to 100 cm, preferably 80 cm to 100 cm.

[0034] Since the swing practice device 1 of the present embodiment has the above-described structure, it is possible to realize unprecedented flexibility and the flexure width X during swinging. Note that this flexure width X can be measured by, for example, shooting a video during swinging and advancing the frames.

[0035] Due to such unprecedented flexibility and deflection width X, particularly as an advantage over ordinary golf clubs, it is possible to experience deflection and return equivalent to or better than those of ordinary golf clubs with an inexpensive and simple structure. Overall, while acquiring the correct form of the golf swing, one can also experience the deflection and return of the shaft of the golf club and master the optimal impact zone where the club head hits the golf ball. Additionally, it is possible to improve swing speed and swing power.

[0036] Furthermore, the swing training device 1 can exhibit ideal weight and mechanical characteristics (such as deflection, return, and trajectory during swinging). Therefore, during swing training using the swing training device 1, it is possible to continuously (repeat) the deflection and return of the swing training device 1 so as to transition in the direction of the arrow. During swing training using the swing training device 1, it is possible to practice repeatedly capturing the swing trajectory on the plane P, which is suitable for acquiring the swing trajectory (see FIGS. 3 and 4).

[0037] As described above, representative embodiments of the present invention have been explained, but the present invention is not limited to these alone, and various design changes are possible, and all of these design changes are included in the technical scope of the present invention.
