Abstract
Description
Technical Field
[0001] The present invention relates to a golf swing practice machine, and more particularly to a golf swing practice machine that can recognize whether a body turn is made through separation of the upper body and the lower body during the rotational movement of a practitioner during a golf swing.
Background Art
[0002] Recently, the number of people enjoying golf has been increasing rapidly. For example, in 2018, the number of golf course visitors was 43 million (four times that of baseball), the number of screen golf course visitors was 12 million, and the number of golfers was 7 million, which can be said to be an era of golf popularization. In particular, as of May 2020, even during the corona situation, golf courses are booming, and the golf clothing market is also growing rapidly. In particular, the number of golfers, who are young people with a relatively stronger will to learn golf, is increasing rapidly.
[0003] When learning golf, it is important to practice the golf swing in a preferable manner. The golf swing motion includes a backswing in which the club is turned backward to strike a golf ball (impact), a reversing motion in which the swing direction is reversed from the highest point of the backswing, a downswing in which the arm is lowered after the reversing motion to strike the golf ball, that is, to reach the impact, and is finished with a release or a finish by the inertia of the swing motion.
[0004] However, although people who try to learn the above-described golf swing take lessons from teaching pros and imitate videos on YouTube (registered trademark), it is difficult to learn the golf swing, it is difficult to practice anytime and anywhere, and continuous practice is impossible.
[0005] In particular, when learning a golf swing, it is important that the knees, pelvis, and shoulders move or rotate in a preferred order and at preferred angles in the continuous motion leading to the backswing, the transition, the downswing, the impact, the release, and the finish. It is difficult for beginners to learn the sequential movement or rotational movement of each part of such a practitioner, and it is difficult for them to recognize how they are actually rotating.
[0006] For example, in a golf swing, a body turn swing is widely known as a desirable one. In the above-mentioned body turn swing (body turn swing: body release), during the downswing, the lower body is first primarily rotated counterclockwise toward the direction of the ball's travel, and subsequently, the upper body follows and rotates secondarily in a torsional swing. In this case, the separation movement between the upper body and the lower body can be effectively performed.
[0007] In the case of the above-mentioned body turn swing, there is a possibility that the centrifugal force during the golf swing increases by increasing the increase in the rotational angular velocity of the torso and further making the center of the torso the center of rotation of the golf swing. Therefore, the above-mentioned body turn swing can increase the club speed and improve the distance of the golf ball.
[0008] In the case of the impact motion by the downswing to realize the above-mentioned body turn swing, the direction in which the front of the upper body faces can increase the centrifugal force only when it rotates ahead of the position of the left arm performing the grip motion of holding the club.
[0009] Therefore, there is a need for a convenient golf swing practice machine that allows a practitioner to directly recognize whether the golf swing motion is a body turn swing or not.
Summary of the Invention
Problems to be Solved by the Invention
[0010] Accordingly, an object of the present invention is to provide a convenient golf swing practice machine that allows a practitioner to directly recognize whether a golf swing motion is a body turn swing or not.

Embodiments for Carrying Out the Invention
[0018] In this specification, the present invention will be described with reference to the attached drawings. However, the present invention can be embodied in various different forms, and thus is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts not related to the description are omitted, and similar parts are denoted by similar reference numerals throughout the specification.
[0019] Throughout the specification, when a part is said to be "connected (connected, contacted, coupled)" to another part, this includes not only the case where it is "directly connected", but also the case where it is "indirectly connected" with other members interposed therebetween. Also, when a part is said to "include" or "have" a certain component, this means that, unless otherwise stated to the contrary, it does not exclude other components, but can further include other components.
[0020] The terms used in this specification are merely used to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly has a different meaning. In this specification, terms such as "including" or "having" are intended to specify the presence of the features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should not be understood as precluding the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.
[0021] FIG. 1 is a perspective view for explaining a golf swing practice machine according to an embodiment of the present invention. FIG. 2 is a perspective view for explaining the main body portion and the coupling portion of FIG. 1. FIG. 3 is a perspective view showing a touch portion coupled to the main body portion of FIG. 1. FIG. 4 is a perspective view for explaining a unit member constituting the touch portion of FIG. 1. FIG. 5 is a cross-sectional view for making the unit member of FIG. 4 vertical.
[0022] As shown in FIGS. 1 to 6, a golf swing practice machine (1) according to a first embodiment of the present invention includes a main body portion (10), a coupling portion (20), and a touch portion (40).
[0023] The club includes a driver, a wood, a hybrid, or an iron club. The grip portion is located at the end of the club. The grip portion corresponds to the portion opposite to the head portion of the club. The grip portion is generally made of a rubber material and corresponds to the portion where the club is held by the palm of the hand.
[0024] The golf swing practice machine (1) can directly confirm whether or not the body turn of the practitioner is formed during the swing practice. That is, when the practitioner practices the swing, a continuous swing motion including a backswing, a turning motion, a downswing, an impact, a release, and a finish is performed. At this time, the practitioner maintains a state in which the grip portion of the golf club is held by the hand.
[0025] Among the above operations, when the hand part holding the grip portion touches the touch portion (40) during the impact operation, it can be determined that it is not a body turn swing.
[0026] The main body portion (10) can be fixed around the abdomen of the practitioner. The main body portion (10) can have a square plate shape. When the practitioner uses the golf swing practice machine (1), the main body portion (10) can be located around the buckle of the belt (refer to reference numeral 2 in FIG. 7) or around the hook of the trousers.
[0027] The main body part (10) can be formed of a material having a certain hardness such as a metal material or a plastic material. Thereby, the main body part (10) can be stably fixed around the abdomen of the practitioner.
[0028] The connecting part (20) extends from each of both side parts of the main body part (10). The connecting part (20) can be bent and extended from both side parts of the main body part 10 at a certain angle. The above angle can be adjusted according to the rounded curvature of the practitioner's abdomen. It may be suppressed that the parts formed by the main body part (10) and the connecting part (20) compress the abdomen of the practitioner. The connecting part (20) can be integrally formed with the main body part (10).
[0029] A mounting groove (25) extending upward from the lower end is formed in each of the connecting parts (20). When the main body part (10) descends to be fixed to a belt or a part of underwear, a part of the belt or underwear is inserted into the mounting groove (25). Thereby, the golf swing practice machine can be mounted on the underwear or belt worn by the practitioner.
[0030] The touch part (40) extends along the normal direction of the main body part (10) from the center of the main body part (10). The touch part (40) can have a variable length. The length of the touch part (40) can be adjusted according to the gender, age, height, and arm length of the practitioner. Therefore, the golf swing practice machine (1) can be easily adjusted according to the build of the practitioner.
[0031] The touch part (40) has a rear end connected to the main body part (10) and a front end opposite to the rear end.
[0032] The front end is touched by the hand of the practitioner holding the club during the swing of the practitioner, and is provided so that it can be confirmed whether the body turn regarding the golf swing of the practitioner has been made.
[0033] The body turn swing (body release) is a twisting form of swing where, during the downswing, the lower body rotates primarily first in the counterclockwise direction, which is the direction of the ball's travel, and then the upper body rotates secondarily. In this case, the separation movement of the upper body and the lower body can be effectively performed.
[0034] Conversely, if the lower body rotates simultaneously with the upper body or the upper body rotates before the lower body, it no longer corresponds to the body turn swing. In this case, since an accurate strike on the golf ball is not performed, there may be problems such as loss of flight distance and deviation of the golf ball's travel direction.
[0035] If the body turn swing is performed smoothly, the lower body rotates counterclockwise first. At this time, the touch part (40) included in the golf swing training machine (1) fixed to the belt or lower clothing of the lower body also rotates counterclockwise together. Subsequently, while the upper body rotates secondarily, the hands and grip part of the practitioner connected to the upper body rotate, enabling the head part to perform an impact operation of hitting the golf ball.
[0036] In the case of the body turn swing, since the touch part (40) is already in a state of being rotated by a predetermined angle, the practitioner can perform the impact operation, subsequent release operation, and finish operation with the tip of the touch part (40) not touching around the hand holding the grip part.
[0037] Conversely, in the case of not performing the body turn swing, the tip of the touch part (40) touches around the hand holding the grip part during the above impact operation. Thereby, the practitioner can recognize whether they are performing the body turn swing or not by themselves.
[0038] In the second embodiment of the present invention, the main body portion (10) can additionally include a hollow first ball (12) with its tip cut off. The first ball (12) extends along the normal direction from the center of the main body portion (10). The hollow formed in the first ball (12) can be connected to the rear end portion of the touch portion (40). The first ball (12) can function as a coupling member that mutually couples the main body portion (10) and the touch portion (40).
[0039] On the other hand, the touch portion (40) is detachably provided on the first ball (12). The touch portion (40) includes a plurality of unit members (41) that can be mutually fastened. As a result, the length of the touch portion (40) can be changed according to the number of unit members (41) that are mutually fastened. The unit member (41) can be formed of a flexible material such as rubber or plastic.
[0040] In the third embodiment of the present invention, each unit member (41) includes a second ball (42), a pocket (44), and an inclined portion (45).
[0041] The second ball (42) has a first outer diameter and can have a hollow with its tip cut off. The second ball (42) can have substantially the same size and shape as the first ball (41).
[0042] The pocket (43) has a second inner diameter that is larger than the first outer diameter. Thus, the pocket (43) is provided so that the second ball (42) that constitutes another unit member to be mutually fastened is inserted and fixed therein.
[0043] The inclined portion (44) connects between the second ball (42) and the pocket (43). The inclined portion (44) can have an inner diameter that increases from the second ball (42) toward the pocket (43).
[0044] The second ball (42), the pocket (43), and the inclined portion (44) can be integrally formed.
[0045] In the fourth embodiment of the present invention, the touch portion (40) is provided so as to entirely cover the first ball (12) and a plurality of unit members (41) that are mutually fastened, and may further include a cover (refer to reference numeral 46 in FIG. 7) made of a soft material. Thereby, when the cover (46) is not in a body turn swing during the downswing of the practitioner, even if the hand part of the practitioner touches the tip of the touch portion (40), the impact on the hand part can be mitigated.
[0046] In the fifth embodiment of the present invention, the touch portion (40) may further include an optical member (refer to reference numeral 48 in FIG. 7) provided at the tip so that the user can turn it on and off.
[0047] The optical member (not shown) is a light generating element and can generate an LED or a laser. For example, when an LED element or a laser generator generates light, the practitioner can visually confirm the rotation angle during the rotation of the lower body.
[0048] FIG. 7 is a perspective view showing a state in which the golf swing practice machine of FIG. 1 is fixed to a belt.
[0049] Referring to FIGS. 3 and 7, by inserting a part of the belt (2) downward into the mounting groove (25) formed in the pair of coupling portions (20), the golf swing practice machine (1) can be easily and stably fixed to the lower body.
[0050] FIG. 8 is a schematic view showing a state in which an address posture is taken using the golf swing practice machine of FIG. 1.
[0051] Referring to FIGS. 7 and 8, in a state where an address posture is taken using the golf swing practice machine, a cover made of a soft material provided so as to entirely cover the touch portion (40) is shown.
[0052] Depending on the number of unit members constituting the touch part (40), the touch part (40) can have a variable length. By having an adjustable length, the touch part (40) enables the user to assume an appropriate addressing posture according to the user's physique or body type.
[0053] The above description of the present invention is merely illustrative, and those with ordinary knowledge in the technical field to which the present invention pertains will understand that it can be easily transformed into other specific forms without changing the technical idea and essential features of the present invention. Therefore, it must be understood that the embodiments described above are exemplary in all aspects and not restrictive. For example, each component described as a single type can also be implemented dispersedly, and similarly, components described as dispersed can also be implemented in a combined form.
[0054] The scope of the present invention is indicated by the claims, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts shall be construed as being included within the scope of the present invention.
