Description

Golf swing exerciser with LED for golf swing impact practice and swing trajectory check {GOLF SWING PRACTICE TOOL WITH LED FOR GOLF SWING IMPACT PRACTICE AND SWING TRACK CHECK}

The present invention relates to a golf swing exercise device. Specifically, when the rotary blade rotates at the time of swing impact, the LED lights up so that it can be easily checked with the naked eye, and when the rotary blade is attached to the strength control ring, the distance is displayed according to the strength of the magnetic force. This relates to a golf swing exerciser equipped with an LED for golf swing impact practice and swing trajectory confirmation that allows the user to easily adjust the strength adjustment ring.

Golf clubs can be divided into a driver for hitting the golf ball a long distance, an iron for sending the golf ball from the fairway to the green, and a putter, a club for short-distance rolling. It consists of a shaft, a head connected to the bottom of the shaft, and a grip connected to the top of the shaft and corresponding to the handle.

Golfers swing a golf club and hit a golf ball using rotational torque obtained by the inertia and centrifugal force of the head.

Meanwhile, in order to improve the distance by hitting the golf ball, the swing trajectory of the golf club, that is, the entire process from the first half of the swing (address-takeaway-swing top) to the second half of the swing (downswing-impact-follow-up) must be perfected. It is important to perform well.

Meanwhile, golf practice that is currently generally conducted indoors includes swing movements using wood or iron or putting using a putter, and in such practice processes, a lot of space is needed for swing movements, and these swing movements are usually You can directly hit the golf ball placed on the tee and determine whether the swing is performed accurately through the sound of the golf ball being struck.

However, in this practice process, a lot of space is required because sufficient swing space must be secured for safety, including the minimum distance of the golf ball. Additionally, the ball must be placed on the top of the tee every time, causing a lot of inconvenience. There was a problem that a large amount of practice balls had to be provided.

To solve this problem, practice golf clubs are posted to practice golf swing movements in a narrow space without a golf ball or in a large space.

An example of such a practice golf club is the practice golf club registered in Korea Patent No. 10-1101280.

As shown in Figures 1 and 2, the practice golf club is formed in the shape of a circular bar and a shaft 10 with a grip 11 formed on the distal end, and is inserted in the shape of a triangular pyramid at the top so that the lower end of the shaft is inserted inside. A main body 20 in which a protrusion 21 is extended, a slit 22 is formed vertically at the other end, a screw tab 23 is formed on the outer surface, and a magnet 25 is stored and fixed on one side, and a cylindrical shape It is formed by a strength adjustment ring 30 that is coupled to the screw tab of the main body and is raised and lowered in the main body, and a fixed wing 40, which is formed in a plate shape with a metal material and one end of which is bolted to the slit of the main body, and a magnet. It is formed in the form of a plate with an attached metal material, and one end is hinged at the center of the fixed wing and is coupled to the magnet of the main body, and by swinging the shaft, the coupling with the magnet is released by the force generated at the time of impact, and the wing is struck from the fixed wing. It includes a rotary blade 50 that rotates to the side.

However, these conventional practice golf clubs allow you to correct your swing posture while practicing your swing by changing the color and hitting sound through the rotation of the rotor blades during the swing. However, there is a problem in that the color change cannot be confirmed with the naked eye in a dark place, and the strength of the golf club is low. There is a scale displayed on the adjustment ring, but there is a problem in that it is difficult to adjust it while checking it with the naked eye.

In addition, these conventional practice golf clubs have a problem in that they do not have versatility because their weight cannot be changed.

Hereinafter, the configuration of a golf swing exercise machine equipped with an LED for golf swing impact practice and swing trajectory confirmation according to the present invention will be described in detail with reference to the attached drawings.

Figure 8 is an explanatory diagram illustrating the process of adjusting the magnetic force intensity using the strength control ring of a golf swing exercise machine equipped with an LED for golf swing impact practice and swing trajectory confirmation according to the present invention, and Figures 9 and 10 are diagrams of the present invention. This is an operation explanatory diagram to explain the operation of a golf swing exercise machine with an LED attached for golf swing impact practice and swing trajectory confirmation.

First, as shown in FIG. 8, the user raises or lowers the strength adjustment ring 130 to change the angle of the rotary blade 144 of the main body 140 through the downward inclined surface 135 to adjust the first magnet 141. The strength of the magnetic force is controlled by adjusting the distance from the device. At this time, as the magnetic force strength of the first magnet 141 is measured by the magnetic force measurement sensor S2, the flying distance is displayed on the display 146 according to the magnetic force strength, so that the user can easily adjust the magnetic force strength according to the distance.

In this state, the reflective film (F) attached to the right side of the rotary blade 144 and the reflective film (F) of the fixed cover 148 located at the bottom are exposed and maintain the same color (for example, green).

And, as shown in FIGS. 9 and 10, the user swings with the same motion as the golf swing motion while holding the grip 111 so that the upper surface of the main body 140 is located at the rear, that is, on the opposite side of the hitting surface. You just need to practice. As the shaft 110 and the main body 140 rotate due to the swing motion, the rotary blade 144 is separated from the magnet 141 by centrifugal force, and the rotary blade 144 rotates, causing the fixed cover at the bottom. When it collides with (148), a ‘clicking’ sound is generated.

At the same time, as the rotary blade 144 collides with the fixed cover 148, the magnetic reed sensor (S1) detects the magnetic force of the second magnet 145 of the rotary blade 144, turns on the LED (L), and rotates the rotary blade 144. ) visually confirms to the user whether or not it is rotating.

And, since the striking sound is generated and the rotary blade 144 rotates at the same time, the reflective film (F) on the opposite side of the rotary blade 144 and the reflective film (F) of the fixed cover 148 located at the top are exposed and have the same color ( For example, orange) appears.

Then, the user can check the color by fixing the gaze on the rotary blade 144 and the LED (L) at the moment of impact, thereby preventing heads-up, and only when an accurate impact is made can the rotary blade 144 rotate to generate a striking sound. Therefore, swing practice is carried out properly.

On the other hand, when the user holds the grip 111 so that the upper surface of the main body 140 faces the user's front and practices the swing with the same motion as the golf swing motion, the address and takeaway are slowly progressed through accurate motion. And, if it stops at the swing top, the rotary blade 144 remains attached to the first magnet 141, but due to an incorrect posture, the address and takeaway proceed quickly, and if it does not stop at the swing top, the swing top The rotary blade 144 is fixed by the first magnet 144 due to centrifugal force at the position, and as it rotates, it hits and generates a 'clicking' sound, and the LED (L) lights up.

Through this, users can practice accurate swings according to the manual.

The present invention can be modified in various ways and can take various forms, and in the detailed description of the invention, only special embodiments thereof have been described. However, it should be understood that the present invention is not limited to the particular form mentioned in the detailed description, but rather is understood to include all modifications, equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims.
