Description

Two-way practice bat for golf swing {TWO-WAY PRACTICE BAT FOR GOLF SWING}

The present invention relates to a practice bat for a golf swing, and more particularly, to a two-way practice bat capable of practicing two types of golf swings with one practice bat.

BACKGROUND OF THE INVENTION [0002] Golf is an exercise in which a golf ball is hit while rotating the shoulder and waist around the spine, and it is a sport that requires a correct and comfortable address posture during a swing.

A series of postures, such as address, takeaway, backswing, downswing, impact, follow-through, and finish, are very important for a correct golf swing. Golf can be said to be an exercise in which posture is more important than any other sport. Elements of posture include swing angle and trajectory, swing time and rhythm, and weight shift during swing. It can be the goal of golf practice to always reproduce the same ideal posture when necessary.

As an outdoor sport, golf can be greatly affected by the weather, and it is difficult to enjoy it in rainy or windy weather. Accordingly, various golf practice devices that can be enjoyed indoors are being developed. For example, one golf practice device has a net screen installed on the front to practice swing posture and hitting by hitting the ball with a real golf club.

However, this practice also requires a fairly wide and high space, and since it is possible at an outdoor driving range or a membership-based indoor golf driving range, steady swing practice may be a hindrance. In addition, since the length from the pitching wedge of the actual golf club to the driver is about 90 to 115 cm, it may be impossible to swing because it hits the ceiling or surrounding furniture when swinging indoors, and only simple putting practice can be done indoors. practice may be limited.

Due to various limitations, there may be a problem in that a golfer cannot correct his or her golf swing posture and practice his or her swing in a place other than an official driving range, that is, at home or in an office.

In addition, applying an impact to a ball using the weight of the head of a club in a golf swing is one of advanced techniques pursued by amateur golfers. In the golf swing, which requires swinging with the whole body, there are not one or two things to keep. Therefore, considering the many factors to be protected, the concentration of power does not occur at the moment of impact, reducing the flight distance of the ball.

Therefore, even according to one's own swing, it is desirable to be able to obtain the maximum distance according to one's ability by putting the weight on the head of the club at the time of impact and impacting the ball with the weight of the head with the weight.

Korean Patent Publication No. 10-2018-0016747, an indoor golf swing trainer, Korean Patent Publication No. 10-2013-0097130, a golf club for swing practice, Korean Patent Registration No. 10-1464717, a golf practice device using a laser beam, Korean Patent Publication No. No. 10-2013-0028320 swing practice golf clubs are disclosed, but these practice equipment includes only one function and has a disadvantage in that it is impossible to practice for multiple purposes.

The present invention provides a two-way practice bat for a golf swing that is not limited by space even when used indoors, can be used for multiple purposes, and can be easily converted to a multi-purpose.

The present invention provides a two-way practice bat for a golf swing in which a rope type and a rod type can be alternately used for golf swing practice, and the use of the rope type and the rod type can be easily switched.

The present invention is a two-way practice bat for a golf swing in which the impact strength and head weight can be adjusted according to the user's physical condition, and the desired feel at impact and the sound of the shaft cutting the wind during swing can be maximized. provides

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, a two-way practice bat for a golf swing includes a flexible shaft, a first grip provided at one end of the flexible shaft, and a first grip provided at the other end of the flexible shaft. A second grip and a spinal core provided inside the flexible shaft, wherein the spinal core has different bending properties when a user swings while holding the first grip and swings while holding the second grip. can

In this embodiment, flexure means bending characteristics, and may be defined by various factors such as strength, repulsive force, and direction. When the first grip is centered on the swing, the shaft may be provided as a rod that does not bend, but it can be said that a case where the shaft has a relatively stronger restoring force than when the second grip is centered on the swing is included. Of course, depending on the direction, it does not bend in a specific direction, but it can be said that, for example, those that can be bent in a 180 degree rotation state have different elasticity.

As one of the configurations for varying the flexibility according to the selection of the grip, the flexible shaft may be provided in a hollow shape, and the spine core may include a row of a plurality of cylinder blocks accommodated in the flexible shaft. can Cylinder blocks may be provided in a row, and may have different flexures while bending or limiting the flexion in turn within the flexible shaft.

For example, the practice bat can be converted into a rod-type practice bat and a rope-type practice bat. Similar to a general golf club, the rod-type practice bat can be used so that the shaft is hardly bent in a straight line, and the posture correction and impact force can be used to improve The rope-type practice bat can be used in a state where the shaft can be bent, and can be used for accurate swing trajectory and speed improvement as it is for practicing swing in a state where power is subtracted.

For example, the cylinder block may include a locker, and the locker may be slidably movable relative to the cylinder block. Accordingly, when a user swings while holding a specific grip, the swing may become the center of the swing, and the rocker may move relative to the cylinder block by gravity or centrifugal force.

If the first grip is the swing center, the rocker can move to another cylinder block that is distal to the swing center by gravity or centrifugal force, and if the second grip is the swing center, the locker can move to another cylinder block that is adjacent to it. You can move in a direction away from the block.

The locker may be provided to include a protrusion that is located inside the cylinder block and protrudes or returns from the cylinder block. When the first grip becomes the swing center, the protrusion of the rocker protrudes from the cylinder block and can be bound to another adjacent cylinder block, and when the second grip becomes the swing center, the protrusion that is engaged is separated from the other adjacent cylinder block can be loosely released.

As another example, the locker may be positioned outside the cylinder block and may be provided to cover all or only a portion of the outer surface of the cylinder block. Accordingly, when the first grip is the swing center, the locker protrudes from the cylinder block and can be bound to another adjacent cylinder block, and when the second grip is the swing center, it can be separated from the other adjacent cylinder block.

When the locker wraps only one surface of the cylinder block, it may have different stiffness depending on the direction, and may be formed like a key to reciprocate between the outer surfaces of the two cylinder blocks.

A practice bat according to another embodiment may include a shaft and at least one wire penetrating the locker, and the wire may guide the movement path of the locker.

Further, when the wire connects the first grip and the second grip, the wire may limit a distance between the first grip and the second grip, and prevent the flexible shaft from extending beyond a certain length even when excessively swinging. Of course, if the purpose is to limit the length of the flexible shaft with a wire, the wire does not necessarily have to pass through the locker.

When using a stick grip or a relatively stiff practice bat, you can add an impact function to the practice bat. To this end, it may include a spring located in the second grip, an impact body supported inside the spring, and an impact adjusting screw exposed to the outside of the second grip from the outside of the spring, and compression of the spring within the second grip by adjusting the impact adjusting screw. The length can be adjusted, and the impact strength can be adjusted according to the user.

A mounting groove may be formed outside the impact adjusting screw, and a replaceable weight mounted in the mounting groove may be further included. The weight may be provided in various weights, and it is also possible to vary the weight according to the user.

For example, since women and men have differences in body structure and strength, the user can practice swing suitable for his/her constitution by varying the weight.

In addition to this, a mounting groove is formed outside the impact adjusting screw, and a replaceable club face or rotating ball mounted in the mounting groove may be further included, and various functions may be added to the practice bat.

The practice bat of the present invention can also be formed with a length of about 90 cm, can be used indoors without being restricted by space, and can be used for multiple purposes such as a rod-type or rope-type practice bat.

In addition, flexion can be directly adjusted by selecting the first grip or the second grip without a specific manipulation. When holding the first grip, it can be used in a rod shape, and when holding the second grip, it can be used directly in a rope shape.

In the practice bat of the present invention, the impact intensity can be adjusted through the impact adjusting screw to suit the user's physical condition, and the head weight can be adjusted by replacing the weight.

The first grip 120 and the second grip 130 may face each other at both ends of one shaft 110 . The first grip 120 and the second grip 130 may be formed to correspond to grips of a general golf club, and may be provided with the same or different shapes, textures, and materials.

For example, the first grip 120 and the second grip 130 may include grips made of rubber or leather, and may be formed in various shapes and materials to prevent slipping and provide excellent gripping feeling.

The flexible shaft 110 may include a single-layer or multi-layer outer shell 112 and may be formed using a material such as silicon. The flexible shaft 110 may be provided with a material capable of being bent, and may be maintained as rigidly as a general golf club according to the change in flexibility of the spinal core 140 located therein, or may be provided flexibly and flexibly. there is.

Spinal core 140 may be provided within hollow shaft 110 . Specifically, the spinal core 140 may include a plurality of cylinder blocks 142, and these cylinder blocks 142 may be provided in a row. The cylinder block 142 may be provided in the same shape and material, but may also be provided in slightly different shapes and materials in some cases.

In this embodiment, the cylinder block 142 is formed in a hollow shape, and a locker 150 may be slidably provided therein. The cylinder block 142 may be provided in a hollow shape, and a first hole 144 and a second hole 146 may be formed in the front and rear, respectively, and the locker 150 may be formed through the first hole 144. The protrusion 152 may be exposed to the outside, and the second hole 146 is formed on the opposite side of the first hole 144 so that the protrusion 152 exposed from the adjacent cylinder block 142 is the second hole 146. ) can be bound to

The first hole 144 and the second hole 146 may be formed in the same shape, but may be formed differently according to the shape of the protrusion 152 . In addition, the protrusion 152 of the locker 150 may always maintain a state of being bound to the first hole 144, and may be partially bound to the second hole 146 and then switch to a separated state.

Referring to (a) of FIG. 2 , when a user practices a swing while holding the first grip 120, the locker 150 in the cylinder block 142 moves in the direction of the second grip 130 while moving in the direction of another adjacent cylinder. It may be bound to the second hole 146 of the block 142 in turn. As the locker 150 is coupled to the adjacent cylinder block 142, the shaft 110 can be firmly fixed in a straight line.

As shown in (b) of FIG. 2 , conversely, when the user switches to the gripping state of the second grip 130, the locker 150 of the cylinder block 142 returns to the inside of the cylinder block 142 and the protrusion 152 It can also be separated from the second hole 146 of another adjacent cylinder block 142, and the shaft 110 can be flexibly bent according to the swing direction. At this time, the protrusion 152 may be designed to remain engaged with the first hole 144 of the cylinder block 142 .

According to this embodiment, two functions can be used using one practice bat 100, and the user can practice various golf swings, such as powerful impact swing practice and smooth speed swing practice. In addition, in this embodiment, impact swing practice can be performed by gripping the first grip 120 without any manipulation, and smooth speed swing practice can be performed by holding the second grip 130 inside out.

In Figure 2, it is switched between a rod-type practice bat and a rope-type practice bat, but in another embodiment, the flexibility can be adjusted in various ways by adjusting the movement amount of the rocker. For example, by adjusting the length and shape of the protrusion and the hole, the flexural characteristics can be variously adjusted, and the flexural properties can be adjusted within a relatively limited range even in a state in which the first grip is held.

In this embodiment, when practicing with the first grip 120 centered on swing, an impact function may be added to the practice bat. Referring to FIG. 3 , the practice bat 100 forms a cylindrical space within the second grip 130, and an impact body 164, a spring 162, and an impact adjusting screw 166 may be sequentially assembled therein. . The impact body 164 and the impact adjusting screw 166 are substituted at both ends around the spring 162, and when the user swings around the first grip 120, the centrifugal force reaches a specific value in the impact section. The impact body 164 may hit the impact adjusting screw 166 .

The user can adjust the basic pressure of the spring 162 by adjusting the impact adjusting screw 166, and can adjust the compression length of the spring 162 according to the user's skill or experience.

When the user uses the first grip 120 as a rod-shaped practice bat centered on the swing, the impact body 164 and the impact adjusting screw 166 are separated by the spring 162, and then the impact body ( 164) can make a 'tak!' bumping sound against the impact adjusting screw 166, and the user can maximize the effect of the swing by directing the sound of a real golf ball hitting it. In addition, the impact section can be confirmed by sound, so the exact position of the impact can be known.

When the user uses the second grip 130 as a rope-type practice bat centered on the swing, smooth speed swing practice can be performed. In addition to this, a sound hole may be formed near the first grip in order to check whether swing practice is performed in the correct direction and trajectory. In a swing using the second grip 130, a flute sound may be generated as the swing speed and direction coincide with the designed speed and direction.

A mounting groove 168 may be formed outside the impact adjusting screw 166, and a weight 170 may be fixed to the mounting groove 168. The user may add a weight 170 to the end of the impact adjusting screw 166 to adjust the weight of the practice bat to suit the user.

In addition, as shown in FIG. 4, by replacing the weights 170, 172, and 174 on the impact adjusting screw 166, various weights can be replaced according to physical conditions or skill levels. In this way, the user can practice swing suitable for his constitution according to age, skill level, gender, physical condition, and the like.
