Description

{GOLF CLUB HAVING FUNCTION FOR GUIDING SWING DIRECTION}

The present invention relates to a golf club, and more particularly, to a golf club having a swing direction guidance function capable of predetermining a swing condition of a golfer's golf club.

A golf club called a golf club (hereinafter referred to as a "golf club") may be used in various types according to the rules of the competition, but generally used are generally referred to as wood, iron, . To understand the characteristics of these golf clubs, it is first necessary to understand how the game progresses.

The most standard golf competition is to end the game by putting golf balls in each of these 18 holes in turn, in all 18 holes.

In order to strike the golf ball, the distance between the starting point and the target hole differs depending on the type of the golf ball. Therefore, it is possible to first aim to hit the golf ball long along the distance, Or may require a mid-range swing.

In other words, 10 of the 18 holes (the first type hole) are defined as a standard two-tone non-negative wave (in the state of positive minus zero, that is, (Second type hole) is defined as an even wave, and the remaining four are defined as one wave (third type hole) as an even wave. Here Wood is used as a golf club for the purpose of sending the ball as far away as possible, so it can be used in the first type hole or the second type hole, . Irons are mainly used in the middle distance, but since the middle distance is very diverse depending on the ability or personality of the golfer, there are many kinds of irons corresponding thereto. (Irons are numbered according to their sizes. For example, 1 iron, 9 iron, etc.).

And, when the golf club used to put the ball into the hole is a putter, and when the golf ball is located at a distance close to the hole, it is generally referred to as "putting" It is a name given to the golf club in terms of functionality.

In addition, there is a special technique for raising a golf ball in a bunker such as a pitch wedge (P / W), a sand wedge (hereinafter, P / W and S / There is a golf club for use.

Thus, the main reason for the existence of various golf clubs is that, in order to put the ball into the hole in various environments with a small number of strokes, it is necessary to cope with countless number of hitting conditions and to vary the personality or individual ability difference This is the reason why we are trying to cope with this problem.

When the golfer hits the ball, the most important part is the strength and direction of the force. However, the strength of the force can be adjusted to some extent by the golf club. In other words, the more experienced golfers tend to adjust their strengths to the diversity of golf clubs possible. In other words, the better the ability to strike the ball while changing the golf club while maintaining a constant body stiffness, the more experienced the golfer can be. Therefore, one of the main functions of the diversity of golf clubs is to help control the strength of the force.

However, even the most skilled golfer in the batting direction has difficulty in coping with the diversity of golf clubs. In other words, despite the diversity of golf clubs, determining the direction of hitting and hitting in the determined direction is a difficult problem to be overcome individually for golfers.

Therefore, the practice of orienting during golf practice is a time-consuming part of golfers. In addition, many golf practice apparatuses have been developed to practice hitting on strength and direction.

A representative example of the golf training apparatus is the golf batting practice apparatus disclosed in the Utility Model Laid-Open Publication No. 1994-0001948 (March 30, 1994) (first publication). This device can detect the direction and speed of a hit golf ball, so that the golfer can check the direction and velocity of the hit ball, so that the golfer knows his or her own striking force (via velocity) You can develop your ability to correct yourself.

However, in the case of the technique disclosed in the above-mentioned first publication, since it is necessary to install in the dimension of the person who operates the golf course, it is possible to easily practice it in a realistic sense by preparing easily at an outdoor golf course, It is not suitable for practice like practice.

[0003] As an example of a golf practice apparatus of a simple structure capable of solving such a problem, there is an improved golf putter disclosed in, for example, Registration Utility Model No. 20-016742 (second publication).

The modified golf putter disclosed in the second publication guides the direction of hitting by irradiating the direction indicator light in a direction perpendicular to the upper portion of the putter face.

However, the putter of the second publication is merely indicating the hitting direction, not only not guiding the exact hit position of the golf ball and the putter, but also realistically, the accurate hitting direction tends to depend more on the golfer's striking posture As an invention that can not be considered, there is a problem in that it can not provide a realistic hitting direction guidance function.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a realistic hitting direction guidance function based on a hitting posture of a golfer, The present invention aims to provide a golf club having a simple structure which can be applied to various golf clubs such as woods and irons as well as putters, and can be prepared and used on the individual level of the golfer.

Second, since the ideal setting value can be constituted by only a single golf club, it is possible to establish an ideal golf swing posture suitable for the individual person at low cost without a huge exercise installation or a professional coach, It is possible. Thus, golf enthusiasts can save on equipment purchasing costs and coaching costs in their hobbies.

Other features and advantages of the present invention will become more apparent from the following description of preferred embodiments of the present invention with reference to the accompanying drawings.

1 is an external perspective view showing an external configuration of a golf club according to an embodiment of the present invention.
2 is an explanatory view showing an operation relationship of a light beam generator according to another embodiment of the present invention.
3 is a block diagram showing an electrical connection relationship between the components of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The accompanying drawings are for comprehension and may not be consistent with the measurement.

1 is an external perspective view showing an external configuration of a golf club 100 according to an embodiment of the present invention. For convenience, the putter will be described as an example of the golf club 100. However, the present invention is not limited to this, and can be applied regardless of kinds of golf clubs such as wood, iron, and the like.

In the drawings, a golf club 100 is roughly divided into a grip 10, a shaft 20, and a head 30. [ The grip 10 corresponds to the handle of the golf club 100 as the name implies and the shaft 20 is the middle portion connecting the grip 10 and the head 30, And has a head face 31 to which a golf ball is contacted.

1, the club head of the present invention includes a first light beam generator 61 installed on the upper end of the head 30 and a first light beam generator 61 installed on the upper end of the head 30, A second light beam generator 62 provided on the shaft 20, a controller 40 installed on the grip, a shaft 20, or a grip 10 mounted on the shaft 20, And a power supply unit 50 (see Fig. 3).

First, the first light beam generator 61 provided on the head 30 acts to project the first light beam 61a toward the target point or the hole 160 as a target. Therefore, in this case, there is a slope between the line of the first light beam 61a projected by the first light beam generator 61 and the ground located at the target point (ground), and the first light beam generator 61 Of the light source means (for example, an LED) of the light source can be adjusted. Further, for example, when the target is located at a high place, that is, when the ball is hit over a high ground from a low ground, the first light beam generator 61 can be adjusted such that the projection height of the first light beam 61a is high . In the case of FIG. 1, the adjustment is performed by the controller 40 provided on the grip 10. As another embodiment, the controller 40 may be configured in the form of a remote controller 45 separated from the golf club 100 (see FIG. 2, reference numeral 45).

The third light beam generator 62 disposed directly below the first light beam generator 61 generates a third light beam 63a that directly projects the golf ball 150 to be hit and also detects the projection angle (I.e., the slope of the light beam with respect to the ground). As the third light beam generator 62 is installed, the golfer can be visually guided to accurately hit the golf ball 150 on the head 30 through the light beam projected onto the golf ball 150. That is, if there is only the first light beam generator 61, the hit direction can be guessed, but the accurate hit of the golf ball 150 to be hit may not be achieved. As a result, (That is, the hole 160 in this case), but the third light beam generator 63 of the present invention provides a function that can solve this problem.

The third light beam generator 63 is positioned directly below the first light beam generator 61 in this embodiment. However, in another embodiment, as shown in Fig. 2, the fifth light beams 65a and 65b projected onto the golf ball 150 from either side or both sides of the head face 31 of the head 30, The first to fifth light beam generators 65-1 and 65-2 may be provided independently or independently of the third light beam generator 63. [ In the case of adding a fifth auxiliary light beam generating portion 65a or 65b for generating a fifth optical beam 65a or 65b projected to the golf ball on both sides of the head face 31, So that it is easier to focus the shot on the golf ball 150 by focusing.

The second light beam generator 62 mounted on the shaft 20 grasps the grip 10 and guides a plurality of second light beams 62a and 62b toward the golfer's foot in a posture to strike the golf ball 150 ). In the case of FIG. 1, the second light beams 62a and 62b are respectively projected toward both feet of the golfer, that is, at points P1 and P2. In this case, a virtual straight line connecting the points P1 and P2 is parallel to the traveling direction of the first light beam 61a. When the second light beams 62a and 62b are projected, the golfer can accurately position the gap between his / her stance position and the golf ball 150. [ The projection angle of the first light beam 61a and the third light beam 63a or the fifth light beams 65a and 65b as well as the second light beams 62a and 62b is transmitted to the input switch 41 of the condenser 40 And registers it in the memory 43 as the golfer's own swing setting value. Therefore, when the golf club 100 of the present invention is later used to perform a golf game or practice, it is possible to accurately find its own stance position (its own relative position with respect to the progress direction of the golf ball and the golf ball) have. Further, the projection angle of each set light beam may be individually updated and registered as necessary.

1, the second light beam generator 62 generates only the two second light beams 62a and 62b, but a plurality of light beams (i.e., three or more light beams) (See FIG. 2). In this case, the intervals between the light projection points P1, P2, P3, P4, P5, and P6 where the plurality of second light beams 62a, 62b, 62c, 62d, 62e, Therefore, the golfer may appropriately determine a stride suitable for the golfer based on these intervals, and may set and register the stride determined in advance in the memory 43 of the controller 40 in advance. In the embodiment shown in FIG. 2, the number of light projecting points projected by the second light beam generator 62 is six. However, the number of light projecting points may be more than ten, for example, Allowing the golfer to more precisely determine his or her stride.

The fourth light beam generator 64 located in the grip 10 also uses a plurality of fourth light beams for the same purpose as the second light beams of the second light beam generator 62 to the plurality of light projection points P1a, P2a, P3a , P4a, P5a, P6a. At this time, the first straight lines P1, P2, P3, P4, P5, P6 connecting the light projection points P1, P2, P3, P4, P5, P6 of the second light beams 62a, 62b, 62c, 62d, 62e, P1a, P2a, P3a, P4a, P5a, P6a of the fourth light beam (64a, 64b, 64c, 64d, 64e, 64f) And the distance between the first straight line and the second straight line is set to, for example, the dimension of the golfer's foot (or the distance between the two straight lines) The size of the shoe in the state of the footwear) and can be set through the input switch 41 of the controller 40. [ Then, the set value is stored in the memory 43 of the controller 40, and when the golf club 100 of the present invention is used again, the golfer can take his or her own stance posture at the set value.

On the other hand, the position detecting sensor 71 is provided on the shaft 20 or the grip 10 (in the embodiment shown in Figs. 1 and 2, the position detecting sensor 71 is mounted on the grip 10) The inclination of the shaft 20 with respect to the ground or the inclination with respect to the vertical line and the orientation of the shaft 20 can be sensed and stored in the memory 43.

The controller 40 includes an input switch 41 for inputting power on and off and a set value, a display section 42 for displaying the input output and setting state of the input switch 41, the first to fifth light beam generating sections 61 At least one of a set value of the light beam projection angle of the golf club 100 and a set value of the angle of inclination of the shaft 20 or the golf club 100 from the attitude detection sensor 71, The display unit 42, the memory, the position detection sensor 71, the speaker 72, and the like, as well as the memory 43 that stores the tilt state And a processor 44. That is, the processor 44 controls the operations of the input switch 41, the display unit 42, and the memory 43 and the operation of the first to fifth light beam generators 61, 62, 63, 64, 65-1, 65- 2), a memory input / output operation relating to the inclination from the posture detection sensor 71 and an azimuth signal, and an operation of the speaker 72, and the like.

The controller 40 of Fig. 1 may be constituted by a remote controller type controller 45 using a local area network such as Bluetooth as shown in Fig. In this case, only the wireless transmitting / receiving unit 41a is built in or enclosed in the grip 10 of the golf club 100, and the remote control type controller 45 is supplied with its own power source (for example, a battery or a battery, Are separately installed. However, the remote controller type controller 45 may provide only an input switch function for an operation command.

3, the power source unit 50 may be a battery or a rechargeable battery, for example, built in the shaft 20 or the grip 10 of the golf club 100, Supply.

The speaker 72 outputs a sound indicative of the result when the set reference value (inclination of the shaft, etc.) and the inclination value when the golfer swings the golf club 100 are substantially equal to each other, Ding-dong, beep, etc.).

The operation of the golf club 100 constructed as above will be described.

First, the golfer controls the direction and altitude of the first light beam 61a of the first light beam generator 61 (i.e., the position of the light beam 61 with respect to the ground) so that the target point, e.g., the hole 160 and the golf ball 150, Is set through the input switch 41 of the controller 40, and the set value (first set value) is stored (step S1).

The third light beam 63a of the third light beam generator 63 and the fifth light beam 63b of the fifth light beam generators 65-1 and 65-2 are transmitted to the golf ball 150 in a state where the first set value is set, (Second setting value) by projecting at least one of the projected angle, the projection angle, and the projection angle of the projection lens 65a and 65b through the input switch 41 (step S2).

The second light beam 62a (for example, the center of the golfer's foot or the forefoot end portion) is placed at the stance position of the golfer through the second light beam generator 62 in a state in which the first set value and the second set value are determined 62b, 62c, 62d, 62e, and 62f to set the angle of the light beam and the light beam projecting angle with respect to the ground to a third set value, and, if necessary, 64b, 64c, 64d, 64e, 64f to the stance position of the golfer (i.e., the heel end portion of the golfer) to project the light beam projection angle of the fourth light beam generator 64 to the input switch 41, And sets the set value as a stance spot suitable for the golfer himself / herself and stores it as a fourth set value (step S3).

The golf club 100 is positioned in a state in which the first set value, the second set value and the third set value (including the fourth set value as the case may be) are set, and at least the inclination and the azimuth of the tilt detection sensor 71 And sets one as a fifth set value (step S4).

When the golf ball 150 advances toward the hole 160 or enters the hole 160 by striking the golf ball by setting the first to fifth set values as the first set value (reference value) The processor 44 of the controller 40 determines that the slope and the azimuth measured from the attitude sensor 71 match the fifth set value (reference value) Accuracy, or expressed through the speaker 72 (step S5).

Thereafter, the first set value is recognized as a value suitable for the golfer's own stance, and the first set value is registered as a first registration set value by matching with a symbol (e.g., name) expressing itself and the first set value (step S6).

In step S5, the golf ball 150 advances in the direction of the hole 160 or enters the hole 160, but the inclination and azimuth measured from the attitude detection sensor 71 are set to a fifth set value (Step S7), the process proceeds to step S4 to set the inclination and the azimuth value, that is, the fifth set value again, and then proceeds to step S5 and step S6.

In step S5, the golf ball 150 does not advance in the direction in which the hole 160 is present, and the tilt and azimuth values measured from the attitude detection sensor 71 also do not coincide with the fifth set value (reference value) (Step S8), the procedure goes to step S1, which is the first step, and the process from step S6 to the final step S6 is repeated while setting all the first to fifth set values again.

In this way, the golfer can perform his / her posture correction while swinging in the guided direction with his / her accurate stance seat and swing angle using only the golf club 100 according to the present invention.

In other words, accurately determining the batting direction of the golf ball with respect to the target or target point requires precise hitting of the golf ball 150, accurate recognition of the golfer on the progress of the hit golf ball 150, , The relationship between the progress of the golf ball and the golf ball and the stance of the golfer (the parallel relationship between the straight line connecting the two legs and the legs and the golf ball advancing direction) and the swing angle of the golf club must be constant, , The inventor of the present invention has found that the golfer's posture is also corrected correctly. That is, the golfer's posture correction is not performed first, but the golfer's posture correction is performed only after the golfer's stance and swing angle suitable for his / . Thus, if the direction, swing angle, and stance position are determined to suit personal body conditions, then the swing intensity can be changed under this established basis, and since the swing strength can be assisted depending on the type of club, The golf club itself according to the present invention can act not only for a beginner but also for athletes to efficiently improve the golf skill. In addition, it has been found that the user can easily access and practically use the target position and the stance position determination with respect to the traveling direction by a simple device.

The present invention has been made on the basis of this finding, and it is an object of the present invention to provide a method for always maintaining a constantly maintained destination direction, a golf ball hit point, a striking stance (standing position of a golfer) Without the need for expensive maps or expensive equipment (including troublesome installations).

In addition, since the golf club of the present invention is suitable for practice, it can be used indoors and outdoors, but it can be simply manufactured so that it can be used for practical use. The efficiency of use of the present invention is high, and it is economically advantageous to not provide any special equipment for actual use.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. That is, although the present invention is applied to a putter in the above embodiment, the present invention is also applicable to wood, iron, and wedge. In the case of applying to the wood or iron, the direction of the target point and the hit position of the golf ball 150 are triangulated by using the third light beam generator 63 and the fifth light beam generator 65-1 and 65-2 And can be determined finely using. Other golf club swing angles and orientations (club positions when hit) are also the same as when applied to the putter of the above embodiment and to wood, iron, or wedge.

When operating with the remote control (45), a receiver can be used to hear the sound when comparing the club posture signal and the reference posture signal at the golf club swing, a non-golfer or co-worker manipulates the remote control, You can only concentrate on.

The first to fifth light beam generators 61, 62, 63, 64, 65-1, and 65-2 may be turned on and off through the input switch 41, It is also possible to separately provide a switch dedicated to turning on and off only the five light beam generators 61, 62, 63, 64, 65-1 and 65-2 so that the golfer can turn on and off only the specific light beam generator .

The light sources of the first to fifth light beam generators 61, 62, 63, 64, 65-1, and 65-2 may be, for example, LEDs, but may also guide the swing of the other golf clubs Other light sources may be used provided they are capable of producing a suitable light beam.

Although the first light beam generator 61 and the third light beam generator 63 are installed at the upper center line of the golf head 30, they may be installed at different locations as required.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of course, this is possible.
