Apparatus for golf address alignment {APPARATUS FOR ALIGNMENT AT ADDRESS IN GOLF SWING}

The present invention relates to a device for golf address alignment, and more specifically, a device that visually confirms whether or not a golfer is aligning her body accurately as aimed when taking an address posture when swinging in a field, thereby assisting in accurate alignment. It is about.

During a golf swing, a golfer takes an address posture after aiming toward a target. It is very important not only for amateur golfers, but also for golfers with a long history to have an accurate address posture.

However, many golfers are not able to address accurately according to the aiming. A wrong address causes an unintentional miss shot. In particular, it is difficult for golfers to align both feet parallel to the target line on which the golf ball flies.

If the alignment of both feet is incorrect during the address process, the golf ball cannot fly in the desired direction even if the swing is perfect.

For example, since the target line through which a golf ball flies and the address line taken by a golfer in an address posture are parallel to each other but spaced apart from each other, the golfer has a feeling that the golfer is facing to the left of the target in the address posture. Because of this, many golfers unconsciously turn their bodies toward the target, and the alignment of the address posture is different, resulting in a miss shot.

In addition, golfers recognize that the ball will go in a different direction even though they have addressed it correctly, and golfers take unnecessary actions to compensate for this.

Not only if you take the wrong address like this, but if you are not sure about the address, it becomes an obstacle to learning the right swing and making accurate shots.

In the golf market, there is a device that helps a golfer stand in a direction perpendicular to a target line to help with address difficulties, but it does not tell whether the feet are accurately aligned in parallel with the target line.

Registered Utility Model Publication No. 20-0494400 discloses a device mounted on an end of a shaft and assisting alignment of feet by irradiating a line laser to the ground. This device not only hinders swing by increasing the weight of the shaft, but also has a problem in that alignment is not easy because the laser line irradiated on the ground changes according to the movement of the hand.

In addition, Utility Model Registration No. 20-2248374 discloses a golf aiming display device that is mounted on a hat and implements a lattice pattern on the ground. Since this display device is mounted on a hat, the alignment of the pattern changes according to the movement of the head, so there is a problem of low stability.

Therefore, it is necessary to visually check and adjust the alignment state of one's body with respect to the target line when taking an address posture so that one can consistently and confidently make a shot in a desired target direction.

Hereinafter, embodiments of a golf address alignment device according to the present invention will be described in detail with reference to the accompanying drawings.

1 shows a golf address alignment device 1 according to an embodiment of the present invention. The address alignment device 1 includes a wire reel 10 and a wire fixing device 20 . 1(a) is a front view of the address alignment device when viewed from above from a golfer's point of view. FIG. 1(b) is a side view of the address alignment device, and FIG. 1(c) is a rear view of the address alignment device.

The wire reel 10 has a wire 13 automatically wound inside the main body 11. When the wire 13 grabs the end of the wire and pulls it, it comes out of the main body 11 through the wire entrance formed on one side of the main body, and when the end of the wire held is released, the wire 13 automatically enters the main body 11 while The winding is a normal automatic wire reel.

Specifically, as can be seen in Figure 5, the wire reel 10 is provided with a winding drum 16 inside the housing of the main body. A wire 13 is wound around the outer diameter of the winding drum 16, and a reel spring 17 is mounted inside the winding drum.

The reel spring 17 is composed of a leaf spring wound in a spiral structure. Inside the reel spring, one end of the reel spring is fixed to the center, and the other end is connected to a wire (13). When the wire 13 is pulled out, the take-up drum 16 rotates, and the reel spring 17 is also pulled, so that the part closer to the center is wound first. At this time, as the length by which the wire 13 is drawn out increases, the tension applied to the wire 13 by the reel spring 17 also increases. When the force applied to the drawn wire 13 is removed, the wire 13 drawn out by the elastic restoring force of the reel spring 17 is automatically re-entered into the main body 11 while being wound around the winding drum 16. . In the present invention, the wire reel is not limited to the structure described above, and is not limited to any structure as long as it is automatically wound and entered when the drawn wire is held and released.

As can be seen in Figure 1, the end of the wire 13 is equipped with a first coupling portion (15). Preferably, the first coupling portion 15 is a member composed of or including a magnet.

Preferably, the first coupling portion 15 has a shock absorbing member 18 at a portion facing toward the main body. When the drawn-out wire 13 is automatically wound into the body 11, it is wound at a fairly high speed. In this case, the first coupling part 15 collides with the body 11 of the wire reel 10 do. To reduce the impact generated at this time, a shock absorbing member 18 may be provided. Preferably, the shock absorbing member 18 may be made of an elastomer such as rubber.

The wire reel 10 may be fastened to and fixed to the shoe, or integrally formed with the shoe. When fastening the wire reel 10 to the shoe, various fastening means may be considered. As can be seen in Figure 2, it can be fastened to the shoe using, for example, a clip 19. For example, the clip 19 is a bent metal member having elasticity and is configured to be restored again after one side is opened. For example, when the open part of the clip 19 is pushed into the shoelace, the clip 19 opens and the shoelace goes into the clip 19 and is inserted, thereby fixing the wire reel 10 to the shoe. . In addition, the clip may be configured with a hairpin or a clothespin, and the type is not limited as long as it is configured to fix the wire reel to the shoe.

On the other hand, the wire fixing device 20 is shown on the left side of FIG. The wire fixing device 20 is installed on the rest of the shoes other than the shoe in which the wire reel 10 is installed.

The wire fixing device 20 includes a body 21 and a second coupling part 25 mounted on the body. The second coupling part 25 is a component coupled to the first coupling part 15 of the wire ring 10 and each other, preferably composed of a magnet or may include a magnet.

When both the above-described first coupling portion 15 and second coupling portion 25 are magnets, they are magnets having different polarities.

In addition, only one of the first coupling portion 15 and the second coupling portion 25 may be composed of a magnet or may be configured to include a magnet. For example, the first coupling portion 15 is composed of a magnet and the second coupling portion 25 may be composed of a metal to which a magnet is attached, conversely, the second coupling portion 25 is composed of a magnet and the first coupling portion 25 is composed of a magnet. The portion 15 may be made of metal.

It is sufficient if the first coupling portion 15 and the second coupling portion 25 are formed in a mutually coupled structure, and there is no limit to their shape. For example, when the first coupling portion and the second coupling portion are magnets, the first and second coupling portions may have a planar structure such that each facing surface is engaged with each other. Alternatively, as will be described later, the first and second coupling parts may be configured to be coupled in a concavo-convex shape.

In addition, the first coupling portion and the second coupling portion are not limited to magnets or metals. It is sufficient if the first and second coupling parts are coupled and separated from each other, and may be configured with, for example, velcro, a member of a connecting ring structure, or the like.

As can be seen in FIG. 2, the wire fixing device 20 may also be installed on the shoe, including the clip 29, and may be configured in various ways with the same or similar configuration as the clip 19 described above.

3, it can be seen that the wire reel 10 is installed on the right shoe and the wire fixing device 20 is installed on the left shoe. Conversely, it is also possible to install the wire reel 10 on the left shoe and the wire fixing device 20 on the right shoe. For reference, below, a case in which the first coupling part and the second coupling part are magnets will be described as an example.

The first coupling portion 15 and the second coupling portion 25 are disposed to face each other. (See Fig. 3 (a)) For example, when a golfer looks down at his/her feet from above, the first coupling part 15 is disposed on the wire reel 10 so as to face the left side, and the second coupling part ( 25) is disposed on the wire fixing device 20 so as to face to the right.

In a state where the wire reel 10 and the wire fixing device 20 are installed in each shoe, when both feet are brought together, the first coupling portion 15 and the second coupling portion 25 are attached to each other by magnetic force. (See (b) of FIG. 3)

When both feet are spread in a state in which the first coupling part 15 and the second coupling part 25 are coupled, the wire 13 is drawn out from the main body 11 . The drawn wire 13 forms an alignment line in a straight line between the feet. (See Fig. 3(c)) Therefore, when addressing with both feet spread, the golfer can complete the address by moving both feet so that the target imaginary line on the ground and the line of the wire 13 are parallel.

After the swing, the first coupling part 15 and the second coupling part 25 may be separated by moving the foot while giving a snap, spreading both feet wider, or applying force to the wire with a club. When the first and second coupling parts are separated, the wire 13 is automatically re-entered into the body 11 and wound.

By using the above-described first coupling portion and the second coupling portion, the golfer can make an alignment line by drawing out the wire in a comfortable standing state without bending the waist or using hands, and by simply releasing the coupling after swinging, the wire automatically can be inserted.

The first coupling portion 15 and the second coupling portion 25 should have sufficient coupling force to form an alignment line by pulling out the wire, and the coupling should be well maintained. In order to keep the coupling well, it is desirable to configure it so that it is not released structurally.

For example, a coupled portion of the first coupling portion 15 and the second coupling portion 25 may have a concave-convex structure. As can be seen in Figure 4, the second coupling portion 25 is configured to have a concave portion 28, the first coupling portion 15 is configured to have a protrusion, the concave portion 28 of the second coupling portion It is preferable to configure the protrusion of the first coupling part 15 to be fitted. In contrast, the first coupling portion 15 may have a concave portion and the second coupling portion 25 may be fastened to the concave portion.

Meanwhile, when the first coupling portion and the second coupling portion are coupled by magnetic force, at least one of the protruding portion and the concave portion may be formed of a magnet. Alternatively, in the first coupling portion and the second coupling portion, except for the protruding portion and the concave portion, magnets may be used.

According to this uneven structure, when force is applied in a direction transverse to the direction in which the first coupling portion 15 and the second coupling portion 25 face each other, the first coupling portion 15 and the second coupling portion 25 ) can prevent the coupling from being released due to displacement in the transverse direction.

Furthermore, it is conceivable to adjust the force applied to the wire to maintain good coupling.

As described above, in the normal wire reel 10, when the wire 13 is pulled out, the tension applied to the wire 13 by the reel spring 17 increases, especially when the wire is drawn almost to the end. The tension applied to the wire 13 by the spring 17 becomes maximum. In this case, when the tension applied to the wire 13 exceeds the bonding force between the first coupling portion 15 and the second coupling portion 25, the coupling of the first coupling portion and the second coupling portion cannot be maintained and separated A problem arises.

According to one embodiment of the present invention, in order to prevent the above-mentioned problems, that is, to prevent the tension applied to the wire from exceeding the coupling force of the coupling member, the reel spring 17 installed inside the winding drum 16 In relation to the reel spring, it is preferable that the width is smaller in the area at the opposite end (the right side of the enlarged view of FIG. 5) than the part where the reel spring is fixed in the center (the left side of the enlarged view of FIG. 5). For example, the width of the reel spring 17 installed inside the winding drum 16 may gradually decrease in a direction away from the centrally fixed part. Alternatively, in relation to the overall length of the reel spring 17 installed inside the winding drum 16, the width of the reel spring may be reduced for a predetermined length at the end side away from the centrally fixed portion. By reducing the width as described above, it is possible to prevent a large increase in tension applied to the wire by the reel spring when the wire is pulled out. That is, it is possible to reduce the amount of tension that interferes with maintaining the coupled state between the first coupling portion 15 and the second coupling portion 25 .

In this regard, as can be seen in [Table 1] below, the applicant conducted a tensile test. Using a spring-type hanging scale, the tension was measured while the wire was withdrawn at 10 cm intervals, and finally, the tension was measured for the case where the wire was pulled out by the maximum length of 63 cm. In the table below, the value of the scale scale measured for the discharged length and the value of the force corresponding to the scale (one scale is 50gf) are displayed together.

In addition, in FIG. 7, based on [Table 1], the change in tension according to the wire discharge length is graphically displayed. As can be seen in Figures 7, Table 1 and Figure 7, at all measurement points, compared to the case of using a reel spring (A) with a constant width, a reel spring (B) with a reduced width for a length of 10 cm at the end It can be seen that the tension is relatively less when used. In particular, when the wire is pulled almost to the end, that is, when the length of the wire is increased from 60 cm to 63 cm, the tension of the reel spring (A) with a constant width increases by 150 gf, whereas the tension of the reel spring (B) with a reduced width In this case, it can be seen that the tension only increased by 50 gf. Accordingly, the possibility of separation of the first coupling portion 15 and the second coupling portion 25 may be reduced by relatively greatly reducing the tension applied when the wire is pulled out almost to the end.

Also, as shown in FIG. 6 , scales or intervals may be marked on the wire 13 . Through this, it is possible to check whether the golfer is standing with the desired stride by looking at the scale or interval marked on the wire drawn out.

The wire 13 may also have different colors based on a predetermined length, so that the length of the wire 13 can be distinguished and recognized. For example, if the wire 13 has a specific color for a predetermined length corresponding to the distance between the feet, the distance between the feet can be easily adjusted during alignment.

Furthermore, the wire 13 is a nylon material and may include a fluorescent material or a luminous material. Therefore, it is possible to increase discrimination during the day through the fluorescent material, and it can be used even at night according to the luminous material.

According to one embodiment of the present invention, an LED device may be added to at least one of the wire reel 10 and the wire fixing device 20 (not shown). The LED device may include a battery, an LED light source, and circuitry. Preferably, the LED light source is located on the lower side of the wire reel 10 or the wire fixing device 20. Accordingly, light is directed toward the ball and wire, making it easier to identify the ball and wire at night. The LED light source may be configured to be switched on manually, or may be configured to be automatically turned on when the first coupler 15 and the second coupler 25 are coupled. In the latter case, when the first coupling portion and the second coupling portion are coupled, the switch of the circuit unit is automatically turned on, and when the coupling is released, the switch may be turned off.

The scope of the present invention is not limited to the above-described embodiments, but may be implemented in various forms of embodiments within the scope of the appended claims. Anyone with ordinary knowledge in the art to which the invention pertains without departing from the subject matter of the invention claimed in the claims is considered to be within the scope of the claims of the present invention to various extents that can be modified.
