Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a line display apparatus with a golf swing path correction function,

[0001] The present invention relates to a line display device for golf, and more particularly to a line display device for golf, which is equipped with a diffraction grating for enlarging and forming a point-like laser light in a + line pattern and lines in a line display device, So that swing can be performed with the correct swing trajectory and the putting stroke can be maintained constantly and correctly.

Generally, a golf swing is to send a golf ball (ball) that is stationary on the ground to a desired distance and direction by rotating the club and putter such as driver, wood, iron and so on in a predetermined orbit.

On the other hand, all the golfers have different physique and competence, but the swing trajectory must be formed according to the basic principles, so if the posture and the swing trajectory are not correct, miss shot which can not seat the ball with the fairway or green is frequently occurred.

In addition to the influence of the swing trajectory, the main factors of such a miss shot are a head up which the golfer can not look at the golf ball before the golf ball is hit and the head is lifted or shaken.

The improper posture, swing trajectory, and head-up of such a golfer may cause the golf ball to swing at the sweet spot of the club face when swinging, It is difficult to accurately impose the golf ball on the desired distance and direction, which makes it difficult to obtain a good score and thus causes mental and physical damage.

Accordingly, there has been a demand for a swing line display device for golfers that can learn a proper posture and a proper swing trajectory in order to send a golf ball to a desired distance and direction, and a line display device of various configurations is proposed in accordance therewith .

However, in the prior art, as an example, a display lamp, to which a laser light source is irradiated, is attached to a headscarf of a cap to a registered trademark of Korean Patent Application No. 20-0336122 (head-up preventing cap for golf using a display lamp) The laser light source is configured to be pointed to the golf ball so that the gaze of the golfer can be focused on the golf ball to prevent the head-up due to the posture failure and correct the posture by itself. However, Or a short line shape, it is not possible to properly align the swing trajectory such as the takeaway (the front part of the backswing), and it is not possible to know at which portion the wrong posture occurs even if the head up occurs There is a problem that the swing correction efficiency is poor.

In addition, conventionally, since the laser light source is irradiated in a short line form, it is difficult to use it as an alignment display for putting practice. Therefore, it is necessary to use a tool such as a club or a plastic rod as an alignment mark for putting practice, However, there is a problem that correct exercise can not be performed properly because the movement of the head, torso, and legs can not be accurately recognized.

In addition, conventionally, since the laser light source has a point shape or an elongated short line shape, it is difficult to confirm the display in a golf course field, and it is difficult to know whether a right swing orbit is practiced correctly.

The case 110 is made of a disc or a rectangle using a synthetic resin so that it is easy to be attached to a cap which is light and wearable by a golfer and is resistant to breakage and is made to be smoothly assembled and disassembled for battery replacement and maintenance And includes an upper case 111 and a lower case 112.

A pair of brackets 112a are formed on the lower surface of the lower case 112 on one side of the case 110. The brackets 112a have an engaging hole h1 for accommodating the rotating shaft 113 on both sides.

A stopper coupling groove 112b for receiving a stopper to be described later is formed between the pair of brackets 112a.

A clamp 114 is coupled to the bracket 112a of the case 110 so as to be detachably attached to the shoulder 210 of the cap 200 worn by the golfer.

The clamp 114 includes a pair of upper clips 114a and a lower clip 114b having an elastic force and formed at one end with an engaging hole h2 which is coaxial with the engaging hole h1 of the bracket 112a, ).

An engaging hole h3 is formed in the width direction between the upper clip 114a and the lower clip 114b so as to be coaxial with the engaging hole h2 and a plurality of teeth are formed on the outer surface The rotation angle adjusting means 115 including the rotating body 115a and the stopper 115b is formed to adjust the irradiating position of the laser light irradiated from the laser device 120 mounted inside the case 110 up and down The rotation angle is adjusted.

The stopper 115b is inserted and fixed into the stopper coupling groove 112b formed between the brackets 112a of the case 110. [

Next, an upper clip 114a and a lower clip 114b accommodating a rotating body 115a having an engaging hole h3 which is coaxial with the engaging hole h2 between the engaging holes h1 of the bracket 112a And then assembled by using the rotating shaft 113.

At this time, the stopper 115b is engaged with any one of a plurality of teeth formed on the rotating body 115a to support rotation of the rotating body 115a.

The laser beam emitted from the laser device 120 can be displayed at a position where the swing trajectory of the golfer can be correctly guided by rotating the case 110 up and down about the rotation axis 113 do.

At this time, when the rotating body 115a rotates up and down about the rotating shaft 113 and the laser line is displayed at a position where the correct swing trajectory can be guided correctly, the stopper 115b is rotated by the rotating body 115a, So as to be prevented from rotating.

Here, the clamp 114 is preferably formed of a synthetic resin having elasticity or a metal such as stainless steel so as to prevent corrosion and firmly fix it.

The laser device 120 is mounted on one side of the inside of the case 110 and forms a line with a + pattern for correctly guiding the swing trajectory to a floor of a cramp or a field at any point, hole 121, a battery 122, and a PCB (Process Control Block) panel (not shown) as shown in FIG. 3, 123, and a laser diode 124. The PCB panel 123 includes a microprocessor, a memory, and a microcomputer circuit having an input / output interface.

The ON / OFF switch 121 is for selectively interrupting the power supply of the battery 122. The PCB panel 123 drives the laser diode 124 based on the power supplied from the battery 122 And the laser diode 124 generates laser light.

The diffraction grating 130 is an optical element made of a plurality of grooves on a plane or concave surface and capable of obtaining a spectrum by interference between diffracted lights in the respective grooves) And is formed in the form of a wafer using silicon.

The wafer-type diffraction grating 130 forms a + line pattern and lines in an optical nanolithography method using a mask having a line pattern and a line-shaped pattern on one side.

In addition, since the diffraction grating 130 can form a + line pattern and line of a minute size by a nanolithography method, the diffraction grating 130 can be made small as an optical element having a size of 3 mm to 5 mm while being a thin film.

Accordingly, the golf line display device 100 according to the present invention can be made light and compact, and is convenient to carry and use.

The diffraction grating 130 having the above-described structure diffracts the point-like laser light emitted from the laser diode 124 of the laser device 120 and expands the laser light into a + pattern and line, Such as grass and the like.

The golf line display 100 according to the present invention can convert a point-shaped laser light into a + pattern and a line, and can form a large and long grass, such as a floor, a ground, and a green. As a result, it is possible to improve the practicing efficiency remarkably.

5 to 7 are views schematically showing the outline of a line display device for golf according to another embodiment of the present invention.

The upper case 111, the lower case 112, the clamp 114, the rotation angle adjusting means 115, the laser device 120, the switch 121, the battery 122, and the like in the apparatus according to another embodiment of the present invention. The PCB panel 123, the diffraction grating 130, and the like are the same categories as those of FIGS. 1 to 4 described above.

However, the upper case 111 and the lower case 112 are formed to be curved so as to improve the adhesion when the laser device 120 is attached to the cap, and the angle of the laser device 120 can be adjusted while being accommodated in the lower case 112 . FIG. 5 shows a state in which the laser device 120 is vertically exposed, and FIG. 6 shows a state in which the laser device 120 is horizontally concealed. The rotation angle adjusting means 115 may apply the aforementioned rotating body 115a and the stopper 115b or may apply known means having the same function. A charging terminal 126 for charging the battery 122 and a charging lamp 127 are provided outside the case 110.

In this case, the laser device 120 is configured to be turned on and off at a predetermined angle corresponding to the signal of the tilt sensor 150. [ The inclination sensor 150 is installed in the PCB panel 123 and generates a signal at a set angle. The laser device 120 is turned on in a range of angles in which the golfer swings his or her head for swinging operation, and the laser device 120 is turned off when the swing is completed and the head is lifted. Of course, such automatic on / off function can be interrupted by the above-described switch 121 or a separate switch.

The operation state of the present invention constructed as shown in FIGS. 1 to 4 will now be described.

The golfer using the line display apparatus 100 according to the present invention is configured such that the upper clip 114a and the lower clip 114b of the clamp 114 formed on the lower surface of the lower case 112 are connected to the shoulder 210 And then the cap 200 is worn.

Next, when the golfer turns on the ON / OFF switch 121, the power of the battery 122 is applied to the PCB panel 123 to drive the laser diode 124 to output laser light.

The laser light output from the laser diode 124 is transformed into a + pattern and line through the diffraction grating 130 and is displayed to induce a swing trajectory to the floor, grass,

Here, the golfer operates the case 110 up and down so as to form a display capable of correctly guiding a clear swing orbit corresponding to the height of the golfer.

At this time, the case 110 is freely and smoothly rotated by the rotation angle adjusting means 115, and is firmly fixed.

Therefore, the golfer forms a display on the floor, lawn, ground, etc. that can correctly guide the swing trajectory formed by the straight and clear + pattern and the line.

Next, the golfer takes an address posture and swings using a club, such as a driver, wood, or iron along the indicated + pattern and line.

At this time, the golfer can immediately see whether the club is moving correctly along the + line pattern and line during the takeaway (front part of the backswing), or whether it moves out of line and into the wrong swing path.

In addition, the golfer can check whether the head is fixed, moved up or down, or head-up when the backswing is operated, depending on whether the alignment of the line with the + pattern is disturbed.

Therefore, when the alignment of the line with the + pattern is disturbed, or the club does not move along the + pattern and line, the golfer can repeat the exercise to stop the swing and maintain the correct posture and swing trajectory. Can be remarkably improved.

In addition, the golfer marks the putting line between the hole formed in the green and the golf ball with a line pattern and a line so as to perform accurate putting.

As described above, the line display device 100 for golf according to the present invention can guide the correct swing trajectory of the golf club during the golf swing, thereby preventing the head-up while inducing an accurate impact.

By showing the + pattern and lines on the floor, on the ground, and on the grass, it induces the swing along the lines and the + pattern without disturbing the aligned laser light, achieving the exact impact, Head-up or head bowing or head movement can be corrected immediately.

Accordingly, the golfer repeatedly repeats the right swing motion along the + line pattern and the line, thereby correcting the wrong posture and the swing trajectory, and at the same time preventing the head-up, thereby realizing the correct swing practice by the golfer himself.

5 to 7, since the laser device 120 is automatically turned on and off by the inclination sensor 150, the power of the battery 122 is used for a long time, and the eyes of the other person are inconvenienced or injured .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
