[Solution] A swing training device comprising a shaft, a head attached to one end of the shaft, and a grip attached to the other end of the shaft, wherein the head has substantially planar front and rear surfaces, and the widths of the front and rear surfaces increase from the end on the shaft side toward the tip.

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]

[0007] In order to achieve the above object, the inventor has conducted extensive research into the shape, structure, materials, specifications, etc. of swing training devices, and has discovered that using a shaft with a specific shape and dimensions is extremely effective in feeling the face during a swing and mastering the appropriate swing trajectory, leading to the present invention.

[0008] In order to solve the above problems, the present invention provides: A club includes a shaft, a head attached to one end of the shaft, and a grip attached to the other end of the shaft, The head having substantially planar front and rear surfaces; the widths of the front surface portion and the rear surface portion increase from the shaft side end toward the tip end; To provide a swing training device characterized by:

[0009] In the swing training device of the present invention, it is preferable that the front surface and the rear surface are substantially parallel to each other.

[0010] In the swing training device of the present invention, it is preferable that the overall length of the head is 25 to 35 cm.

[0011] In the swing training device of the present invention, it is preferable that the overall width of the head is 5 to 7 cm.

[0012] In the swing training device of the present invention, it is preferable that the mass of the head is 50 to 500 g.

[0013] In addition, the swing training device of the present invention preferably has a total length of 106 to 127 cm. [Effects of the Invention]

[0014] The swing training device of the present invention allows a person 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 desirable swing trajectory. [Brief explanation of the drawings]

[0015] [Figure 1] 1 is a schematic diagram of a swing training device 1 according to one embodiment of the present invention. [Figure 2] 2A, 2B, 2C, 2D, and 2E are a front view, a right side view, a left side view, a top view, and a cross-sectional view along line AA, of a head 4 constituting the swing training device 1 of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] 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.

[0017] Fig. 1 is a schematic diagram 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 generally formed of a long rod body.

[0018] As a result of extensive research into the shape, structure, materials, and specifications of swing training devices, the inventor has discovered that a swing training device with the following specific configuration is extremely effective in improving head speed and mastering an accurate swing trajectory while feeling the weight of the head and the face of the club head (the hitting surface or horizontal surface) that hits the golf ball.

[0019] That is, there is no particular limit to the overall length of swing training device 1 as long as it is within a range that achieves the effects of the present invention, but it is preferable that the overall length be approximately 106 cm to 127 cm (approximately 42 in to 50 in).Within this range, an appropriate length of 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. The mass of swing training device 1 is preferably roughly the same as or heavier than the mass of a golf club, for example 300 to 900 g, but is preferably 500 to 900 g from the viewpoint of obtaining the effect of increasing head speed.

[0020] The swing training device 1 has a shaft 2, a head 4, and a grip 6. These components will be described in detail below.

[0021] The shaft 2 is a long rod with a circular cross section that has approximately the same thickness (outer diameter) from one end to the other, and a head 4 is attached to one end (tip end) of the shaft 2, and a grip 6 is attached to the other end (base end). The shaft 2 may be solid or hollow.

[0022] Various materials can be used for shaft 2 as long as the effects of the present invention are achieved, such as wood, bamboo, or resins such as polypropylene and polycarbonate. Shaft 2 may also be flexible, allowing the user to swing swing training device 1 while feeling the flex, contributing to mastering an accurate swing trajectory. That is, a known golf club shaft or a practice shaft can be used as shaft 2.

[0023] Head 4 is a component attached to the tip of shaft 2 that also functions as a weight, increasing the centrifugal force generated in swing training device 1 during a swing and allowing the user to feel the face of the club head hitting the golf ball. Shaft 2 can be inserted into recess 45 of head 4 and connected with adhesive, double-sided tape, or the like. Therefore, head 4 may be made of various resins including rubber and silicone, and may have a metal component built in.

[0024] The head 4 has a substantially flat front surface 41 and a rear surface 43 that are substantially parallel and face each other (see FIGS. 2(c) and 2(d)). The front surface 41 and the rear surface 43 each increase air resistance during a swing, just like the ball-hitting surface of the club head. The reason for providing two surfaces, the front surface 41 and the rear surface 43, is so that either surface can be used.

[0025] The front surface portion 41 and the rear surface portion 43 are generally flat surfaces, facing generally in opposite directions on the circumferential surface of the head 4, and facing each other. Therefore, the front surface portion 41 and the rear surface portion 43 are in a generally parallel positional relationship, and the distance (thickness) between the front surface portion 41 and the rear surface portion 43 is generally constant.

[0026] As shown in Figures 2(a) and 2(c), the shaft-side end 4a of the head 4 is the narrowest and circular, and as shown in Figure 2(a), the widths of the front surface 41 and rear surface 43 of the head 4 gradually increase from the shaft-side end 4a toward the other end 4b (tip), with the widest portion P being located closer to the end 4b (tip) than the center of the head 4 over the entire length, and the width at the end 4b (tip) being preferably wider than the shaft-side end 4a. In this embodiment, the front surface 41 and rear surface 43 have roughly the same area, and either may be referred to as the front surface or the rear surface. However, the front surface 41 and rear surface 43 may have different areas, and either one may be designated as the front surface.

[0027] The head 4 has a substantially circular or elliptical (or athletics stadium-like) cross section from the end 4a on the shaft 2 side up to a predetermined distance (approximately 1 / 4 to 1 / 3 of the total length of the head 4). This portion has a substantially uniform diameter, which may be, for example, about 20 to 30 mm. From there to the other end 4b, the distance (thickness) between the front surface 41 and the rear surface 43 remains roughly constant as shown in Figures 2(b) and 2(c), while the width of the front surface 41 and the rear surface 43 gradually increases, resulting in a flatter shape as shown in Figure 2(a). This width may be, for example, roughly 55 to 65 mm.

[0028] Therefore, the width of the front portion 41 and the rear portion 43 increases from one end 4a to the other end 4b, forming a teardrop, a water drop, or a rice paddle shape (see the dashed line in Figure 2(a)).

[0029] In contrast, in the surface connecting the front surface 41 and the rear surface 43, the thickness of the head 4 increases slightly from the end 4a toward the end 4b, but remains roughly constant (see FIGS. 2(c) and 2(d)). The maximum thickness of the head 4 (the distance between the front surface 41 and the rear surface 43) may be roughly 25 to 35 mm. With the above-described configuration, the user can practice swinging while more reliably feeling the centrifugal force generated in the swing training device 1 and the face of the club head hitting the golf ball through the front portion 41 and the rear portion 43. In addition, the user can feel the face of the front portion 41 or the rear portion 43 (i.e., moderate air resistance) when practicing swinging.

[0030] In addition, the overall length of the head 4 is preferably about 25 to 35 cm, and the mass of the head 4 is preferably about 50 to 500 g.

[0031] Next, the grip 6 may be a grip 6 used for various sports, but a golf grip is preferable. The shaft 2 may be inserted into a recessed portion (not shown) of the grip 6 and connected with adhesive, double-sided tape, or the like.

[0032] The grip 6 is molded using an elastic material, and a finely textured pattern that also serves as an anti-slip feature may be formed on the outer circumferential surface of the grip 6, for example, by embossing. The inner diameter of the grip 6 is constant, but it is preferable that the outer diameter gradually increases toward one end of the grip 6 (the grip end side). Alternatively, the grip 6 may have projections and depressions formed along the shape of the user's hand (see FIG. 1), which allows the user to learn the correct way to hold the device.

[0033] As the elastic material for the grip 6, 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 6 can be used.

[0034] 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.

[0035] 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]
