A golf putting practice device for improving accuracy by predicting, applying green speed to practice distance sense for the batted ball, and by using a binding device on the back of the backswing and hitting part of the putter head to familiarize the body with a 90-degree blow is about

Golf is a game in which you hit a golf ball with a golf club into a hole cup that is a certain distance away from a wide field to make a hole in.

In general, after a tee shot with a driver and a second shot that goes up to the green with an iron, the ball that rises on the green is finally put into the hole cup. it is said

However, with regard to putting practice, since the golf course is mainly located in the suburbs, it is difficult to practice normally, and there is a trend to simply practice putting indoors or outdoors by using a separately manufactured golf putting practice device.

In this regard, most of the conventional putting practice devices are provided with a simple configuration including an artificial mat, forming a hole cup on one side, placing a golf ball on the other side, and putting it into the hole cup. This is helpful in the case of a short putting distance and a flat green, but since the green of the actual golf course is not flat and the putting distance may vary, there is a problem that the conventional putting practice device alone is not very helpful on the green of the actual golf course.

In addition, there was a problem in that when the user swings the putter, the angle between the putter head and the golf ball is digitized when the golf ball is hit, and the swing speed of the putter is accurately quantified and cannot be shown to the user.

The first spring 211 , the second spring 212 , and the third spring 213 are sequentially disposed on one side of the movable body 200 , and when the user swings the putter 1 , the putter head moves to the first The spring 211 , the second spring 212 and the third spring 213 come into contact with each other.

When the putter head swings the putter to press the first spring 211 , the second spring 212 , and the third spring 213 , each of the springs 211 , 212 , and 213 changes in length. Information on such length change may be detected by the angle sensor unit 220 included in the movable body 200 .

The movable body 200 includes an angle sensor unit 220 therein, and the angle sensor unit 220 includes a first sensor unit 221 , a second sensor unit 222 , and a third sensor unit 223 . .

The first sensor unit 221 is disposed close to one end of the first spring 211 , and when the length of the first spring 211 is shortened by pressure, the shortened length may be detected.

The second sensor unit 222 is disposed close to one end of the second spring 212 , and when the length of the second spring 212 is shortened by pressure, the shortened length may be detected.

The third sensor unit 223 is disposed close to one end of the third spring 213 , and when the length of the third spring 213 is shortened due to pressure, the shortened length may be detected.

4A, 4B and 4C show the moment the putter 1 comes into contact with the first spring 211, the second spring 212, and the third spring 213 of the movable body 200 in the embodiment of the present invention. is a plan view of

Referring to FIG. 4A , when the putter 1 is closed and hit by the movable body 200 , such as when the putter is closed and hit by a golf ball during golf putting, the length change of the first spring 211 is the largest, and the third spring (213) has the smallest length change.

Referring to FIG. 4B , when the putter 1 is opened and hit by the movable body 200 , such as when the putter hits a golf ball when putting golf, the change in length of the first spring 211 is the shortest, and the third spring (213) has the largest length change.

Referring to FIG. 4C , when the putter 1 is accurately struck by the spring 210 of the movable body 200 as the putter accurately hits a golf ball during golf putting, the first spring 211 and the second spring 212 ) and each change in length of the third spring 213 will all appear the same.

The calculation unit 300 receiving the information on the length change as described above calculates the angle at which the putter 1 comes into contact, and the calculated angle information is transmitted to and displayed on the display unit 400 .

Accordingly, the user can easily determine whether his or her putting is correct through the angle information transmitted to the display unit 400 , and can repeatedly practice the putting swing so that his or her putting direction is correct.

6 is a plan view of another embodiment of the putting practice apparatus 10 according to the present invention.

Referring to FIG. 6 , the bottom part 100 further includes a putter connection part 130 .

The putter connection part 130 is located on the other side of the bottom part 100 and is attached to the guide rail 110 so that the longitudinal axis of the guide rail 110 and the axis of the putter connection part 130 coincide.

The putter connection unit 130 is configured so that a magnet is built-in therein, and when the material of the putter head of the putter 1 is magnetic, the putter connection unit 130 and attractive force can act.

The putter connection unit 130 is not directly attached to the putter head of the putter 1 by magnetic force, but when the user stands in front of the moving body 200 for putting practice and backswings the putter, the backswing trajectory serves to assist .

Specifically, when the user backswings the putter 1, it is preferable that the swing direction coincides with the longitudinal direction of the guide rail to accurately hit the movable body 200. The putter connection part located near the backswing point of the putter 1 Reference numeral 130 serves to provide a magnetic force to the putter head so that the direction of the backswing is parallel to the direction by magnetic force even if it is not parallel to the direction to be put.

That is, when the user swings the putter 1 toward the movable body 200 , the swing direction of the putter 1 does not deviate from the left and right of the desired direction by the magnetic force of the magnet, and the guide rail 110 in the longitudinal direction. It is possible to accurately swing the spring 210 of the movable body 200 along an imaginary line parallel to.

In addition, the putter connection unit 130 further includes a balance rubber band 132 and a display member 410 .

The balance rubber band 132 is configured to be connectable to the putter head of the putter (1).

When the user swings the putter 1 toward the movable body 200 by the elastic force of the balance rubber band 132 , the downswing can be maintained correctly.

Specifically, the balance rubber band 132 is to help the user's putting swing so that the direction of the downswing during putting can be formed in the longitudinal direction and the vertical direction of one side of the movable body 200 .

On the other hand, the putter connection unit 130 further includes a ring groove (131).

The ring groove 131 is formed through the putter head of the putter 1 in a ring shape so that it can be connected by a general rubber band (not shown).

When the general rubber band (not shown) is hung on the ring groove 131 and the general rubber band (not shown) is hung on the putter head at the same time, the swing trajectory is wrong when connecting the putter 1 and the balance rubber band 132 and swinging. We can help you avoid going.

Therefore, it is possible for the user to practice putting the putting practice device 10 so that the backswing or downswing does not deviate from the correct putting direction when putting.

The display member 410 displays information about the length displacement of the balance rubber band 132 when swinging the putter 1 to which the balance rubber band 132 is connected.

At this time, although not shown, the putter connection unit 132 calculates the information sensed by the balance rubber band sensor module (not shown) and the balance rubber band sensor module (not shown) for detecting information on the change in the length of the balance rubber band 132 . It includes a balance rubber band calculation module (not shown). Since the information calculated by the balance rubber band calculation module (not shown) is transmitted to and displayed on the display member 410, the user can visually recognize it.

7 is a block diagram showing the configuration of the putting practice apparatus 10 according to a preferred embodiment of the present invention.

In the illustrated embodiment, the putting practice apparatus 10 includes a control unit 600 as a configuration for control. The control unit 600 is connected to the distance sensor unit 120, the angle sensor unit 220, the calculation unit 300, and the communication unit 500 as a lower configuration, and the control unit 600 and the display unit 400 are energably connected. .

As described above, the distance sensor unit 120 is configured to detect information about a moving distance and a moving speed when the user hits the moving object 200 with the putter 1 as described above.

At this time, the information sensed by the distance sensor unit 120 is transmitted to the operation unit 300 . The calculator 300 calculates the moving distance and the moving speed by using the transferred information about the moving distance and the moving speed.

When the angle sensor unit 220 strikes the movable body 200 with the putter 1 as if the user is putting, the first spring 211 , the second spring 212 and the third spring 213 detect a change in length. The first sensor unit 221 , the second sensor unit 222 , and the third sensor unit 223 may detect and detect the putting angle based thereon. A description thereof will be omitted since it is the same as described above.

Meanwhile, the information sensed by the angle sensor unit 220 is transmitted to the operation unit 300 . The calculating unit 300 calculates the putting angle by using the information about the length change of each of the transmitted springs (211, 212, 213). At this time, the putting angle means an angle formed by a direction in which the putter 1 hits one side of the movable body 200 and a longitudinal direction of one side of the movable body 200 .

Specifically, the calculation unit 300 calculates the length of one side of the movable body 200 and the length of the first spring 211, the second spring 212, and the third spring 213 based on a change in the length of the golf ball in a trigonometric manner. You can calculate the putter face angle.

When the swing direction of the putter 1 and the angle of the putter face form 90 degrees, the user can perfectly send the golf ball in the desired direction. Based on this, the angle of the putter face can be inferred.

Since the display unit 400 described above also displays the angle information calculated by the calculation unit 300 based on the information of the angle sensor unit 220 , the user can visually recognize it and utilize it for putting practice.

Meanwhile, the operation unit 300 is energably connected to the communication unit 500 , and the communication unit 500 is energably connected to the display unit 400 . The movement distance information, movement speed information, and angle information of the operation unit 300 transmitted to the communication unit 500 are calculated in a format transmitted to the display unit 400 and transmitted to the display unit 400 .

In this case, the communication unit 500 and the display unit 400 may be connected to each other through wired or wireless communication.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains within the scope not departing from the technical spirit and scope of the present invention described in the claims to be described later.
