Description

[Technical Field]

[0001] The present invention relates to a swing trainer that can be used to practice a swing, such as a golf swing. [Background technology]

[0002] Conventionally, various training devices have been used to practice golf swings, and for example, a rod-shaped golf swing training device that imitates a golf club is known. This golf swing training device allows a player to master an accurate swing form by repeatedly practicing swings, while improving swing speed and swing power.

[0003] For example, Patent Document 1 (JP 2002-204845 A) discloses a golf swing training device having a rigid shaft portion with a grip portion on the surface as a gripping portion, and a pendulum portion extending from the tip of the shaft portion, which is flexible and has elasticity to return to an approximately straight state.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-204845 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the golf swing training device of Patent Document 1 is intended to bend greatly during a swing and is made of a very soft elastic material, as shown in Figure 6 of Patent Document 1. For this reason, the golf swing training device only allows practice swings as if using a club or iron, giving a slight feeling of swing, and it is difficult to feel the face during a swing, so it does not lead to strengthening the stability of the swing trajectory.

[0006] Therefore, the present invention has been made to address the above-mentioned problems, and the problem that it aims to solve is to provide a swing training device that allows a user to experience the face while swinging while mastering the correct form of a swing such as a golf swing, and also allows a user to master an accurate swing trajectory. [Means for solving the problem]

[Brief explanation of the drawings]

[0014] [Figure 1] 1A is a front view, FIG. 1B is a side view, and FIG. 1C is various cross-sectional views of a swing training device 1 according to one embodiment of the present invention. [Figure 2] 2 is a view of the shaft 2 of the swing training device 1 of FIG. 1 as seen from the tip side. DETAILED DESCRIPTION OF THE INVENTION

[0015] Representative embodiments of the swing training device of the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to these. In the following description, the same or equivalent parts will be designated by the same reference numerals, and duplicate explanations may be omitted. Furthermore, since the drawings are intended to conceptually explain the present invention, the dimensions and ratios of the components shown may differ from the actual ones.

[0016] 1A is a front view, FIG. 1B is a side view, and FIG. 1C is a cross-sectional view of a swing training device 1 according to one embodiment of the present invention. As shown in FIG. 1, the swing training device 1 is made up of a long rod.

[0017] As a result of extensive research into the shape, structure, materials, specifications, etc. of swing training devices, the inventors have discovered that a swing training device having the following specific configuration is extremely effective in improving head speed and mastering an accurate swing trajectory while feeling the face.

[0018] The swing training device 1 has a shaft 2 and a grip 4. The shaft 2 is a long rod body, and the grip 4 is provided at one end of the shaft 2.

[0019] The shaft 2 has a substantially planar front surface portion 21 and a substantially planar rear surface portion 23 on both sides. That is, the front surface portion 21 and the rear surface portion 23 are generally flat surfaces and face generally opposite directions on the circumferential surface of the shaft 2. Alternatively, the front surface portion 21 and the rear surface portion 23 can be said to face each other. Therefore, the front surface portion 21 and the rear surface portion 23 are in a generally parallel positional relationship.

[0020] In this embodiment, the front surface 21 and the rear surface 23 have approximately the same area, and either may be called the front surface or the rear surface. However, the front surface 21 and the rear surface 23 may have different areas, and either surface may be designated as the front surface.

[0021] The shaft 2 has a shape in which the longitudinal cross section increases from one end 2a (the end on the grip 4 side) to the other end 2b (the tip). Here, the longitudinal cross section is a cross section of the shaft 2 cut along a plane perpendicular to the axial direction of the shaft 2.

[0022] That is, as shown in FIG. 1(c), the shaft 2 has a generally circular or elliptical (or athletics stadium-like) cross section (see FF cross section) from the end 2a on the grip 4 side to a predetermined distance (i.e., the same as or slightly longer than the length of the grip 4; for example, 300 to 400 mm). This section has a generally uniform diameter, for example, about 10 to 20 mm. From one end 2a to the FF cross section, the shaft 2 is generally circular, but from there to the other end 2b, the widths of the front surface 21 and the rear surface 23 gradually increase, resulting in a flattened shape in the EE cross section, DD cross section, CC cross section, BB cross section, and AA cross section.

[0023] From the grip 4 to the tip side of the FF cross section, the thickness of the shaft 2 gradually increases, but the thickness (or thickness) is generally constant at the front surface 21 and the rear surface 23 (see FIG. 1(b)). This thickness, i.e., the distance between the front surface 21 and the rear surface 23, may be, for example, approximately 30 to 40 mm. Therefore, the width of the front surface 21 increases from one end 2a to the other end 2b, forming a teardrop or water drop (or rice paddle) shape (see FIG. 1(a)).

[0024] In contrast, in the plane connecting the front surface portion 21 and the rear surface portion 23, the thickness of the shaft 2 increases further toward the end portion 2b, and reaches its maximum near the end portion 2b (see the cross-sectional views from AA to EE in FIG. 1(c)). The maximum thickness of the shaft 2 (maximum width of the front surface portion 21 and the rear surface portion 23) may be, for example, 60 to 70 mm. In this case, the user can feel the face of the front surface portion 21 or the rear surface portion 23 when practicing swinging.

[0025] Various materials can be used for the shaft 2 as long as they achieve the effects of the present invention, and may be made of, for example, wood, bamboo, or resins such as polypropylene and polycarbonate. The shaft 2 according to this embodiment can be produced, for example, by preparing a rod having a substantially circular or substantially elliptical cross section and then carving or cutting the thick tip end side (end 2b side) of this rod into substantially parallel surfaces (front surface portion 21 and rear surface portion 23).

[0026] The shaft 2 may be flexible, which allows the user to swing the swing training device 1 while feeling the flex, which contributes to mastering an accurate swing trajectory.

[0027] The total length of the swing training device 1 including the shaft 2 is not particularly limited as long as it is within a range that achieves the effects of the present invention, but for example, the total length may be approximately 90 cm to 120 cm, and preferably approximately 90 cm to 117 cm. Within this range, an appropriate length for the golf swing training device that achieves the effects of the present invention can be selected according to the user's physique and height, and the device can also be conveniently stored in, for example, a golf bag.

[0028] Furthermore, it is preferable that the mass of the swing training device including the shaft 2 is roughly the same as or heavier than the mass of the golf club, for example, 300 to 900 g, but from the viewpoint of obtaining the effect of increasing head speed, it is particularly preferable that it be 500 to 900 g.

[0029] Next, the grip 4 may be a grip 4 used for various sports, but a golf grip is preferable. The shaft 2 may be inserted into the recess of the grip 4 and connected with adhesive, double-sided tape, or the like.

[0030] The grip 4 is molded using an elastic material, and it is preferable that a fine uneven pattern that also serves as an anti-slip feature is formed on the outer circumferential surface of the grip 4, for example, by embossing. It is also preferable that the inner diameter of the grip 4 is constant, but the outer diameter gradually increases as it approaches one end side of the grip 4 (grip end side).

[0031] As the elastic material for the grip 4, for example, rubber or synthetic resin elastomer is preferably used, but it is not limited to these, and any material that can be insert molded and has the elasticity and flexibility suitable for the grip 4 can be used.

[0032] Since the swing training device 1 of this embodiment has the structure described above, it is possible to master the correct form of a swing such as a golf swing, while repeatedly experiencing the swing trajectory while feeling the face, thereby accurately acquiring a preferred swing trajectory.

[0033] Representative embodiments of the present invention have been described above, but the present invention is not limited to these, and various design modifications are possible, all of which are included in the technical scope of the present invention. [Explanation of symbols]
