Description

Device for aligning golf addresses

The present invention relates to a device for golf address alignment. Specifically, a device that assists in accurate alignment by visually confirming whether the golfer is aligning his or her body exactly as aimed when taking the address posture when swinging in the field. It's about.

During a golf swing, the golfer aims toward the target and then assumes an address posture. It is very important to have an accurate address posture not only for amateur golfers but also for golfers with old skills.

However, many golfers are unable to address accurately according to their aiming. Incorrect address causes unintentional miss shots. In particular, it is difficult for golfers to align both feet parallel to the target line where the golf ball flies.

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

For example, the target line through which the golf ball flies and the address line that the golfer takes in the address posture are parallel to each other but are separated from each other, so the golfer has the feeling that he 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 their address posture changes, resulting in mishits.

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

In this way, not only if you address incorrectly, but if you are not sure about your address, it becomes an obstacle to learning the correct swing and making accurate shots.

In the golf market, there are devices on the market that help golfers stand in a direction perpendicular to the target line to help address difficulties, but they cannot tell whether both feet are aligned exactly parallel to the target line.

Korean Registered Utility Model Publication No. 20-0494400 (announcement date: October 6, 2021) discloses a device that is mounted on the end of a shaft and irradiates a line laser to the ground to help align the foot. This device not only hinders swing by increasing the weight of the shaft, but also has the problem of making alignment difficult because the laser line irradiated to the ground varies depending on the movement of the hand.

In addition, Korea Registered Utility Model Publication No. 20-2248374 (announcement date: May 10, 2021) discloses a golf aiming display device that is mounted on a hat and implements a grid-shaped pattern on the ground. Since this display device is mounted on a hat, the alignment of the pattern changes depending on the movement of the head, which has the problem of low stability.

Therefore, in order to be able to consistently and confidently shoot in the desired target direction, it is necessary to visually check and adjust the alignment of one's body with respect to the target line when taking the address posture.

In order to solve the above-mentioned problems, the present invention aims to visually check and adjust the alignment of one's body with respect to the target line when taking an address posture.

Additionally, the purpose is to enable the device of the present invention to be used simply by moving both feet before and after a shot.

Hereinafter, embodiments of a golf address alignment device according to the present invention will be described in detail with reference to the attached 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. Figure 1 (a) is a front view of the address alignment device as seen from above from a golfer's perspective. Figure 1(b) is a side view of the address alignment device, and Figure 1(c) is a rear view of the address alignment device.

The wire reel 10 is provided with a wire 13 that is automatically wound inside the main body 11. When the wire 13 is pulled by holding the end of the wire, it comes out of the main body 11 through a wire entrance formed on one side of the main body. When the end of the wire held is released, the wire 13 automatically enters the inside of the main body 11. 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 installed inside the winding drum.

The reel spring 17 is composed of a leaf spring wound in a spiral structure. Inside the winding drum, one end of the reel spring is fixed to the center, and the other end is connected to the wire 13. When the wire 13 is pulled out, the winding drum 16 rotates, and the reel spring 17 is also pulled, so that the part closest to the center is wound first. At this time, as the length to which the wire 13 is drawn increases, the tension applied by the reel spring 17 to the wire 13 also increases. When the force applied to the drawn wire 13 is removed, the drawn wire 13 is automatically wound around the winding drum 16 and re-enters the main body 11 due to the elastic restoring force of the reel spring 17. . In the present invention, the wire reel is not limited to the structure described above, and there is no limitation to any structure as long as it holds the drawn wire and automatically winds it in when released.

As can be seen in Figure 1, the first coupling portion 15 is mounted on the end of the wire 13. Preferably, the first coupling portion 15 is a member made of a magnet or including a magnet.

Preferably, the first coupling portion 15 has a shock absorbing member 18 on a portion facing the main body. When the drawn wire 13 is automatically wound into the main body 11, it is wound at a fairly high speed. In this case, the first coupling portion 15 collides with the main body 11 of the wire reel 10. do. To reduce the shock that occurs 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 and fixed to the shoe, or may be formed integrally with the shoe. When fastening the wire reel 10 to a shoe, various fastening means can 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 with elasticity and is configured to be restored after opening on one side. For example, when the open portion of the clip 19 is pushed into a shoelace, the clip 19 opens and the shoelace is inserted into the inside of the clip 19, thereby fixing the wire reel 10 to the shoe. . In addition, clips can be made of hairpins, clothespins, etc., and there is no limit to the type of clip as long as it can be used to secure a wire reel to a shoe.

Meanwhile, a wire fixing device 20 is shown on the left side of Figure 1. The wire fixing device 20 is installed on shoes other than the shoe on which the wire reel 10 is installed.

The wire fixing device 20 includes a main body 21 and a second coupling portion 25 mounted on the main body. The second coupling portion 25 is a component that is coupled to the first coupling portion 15 of the wire ring 10, and may preferably be made of a magnet or may include a magnet.

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

Additionally, only one of the first coupling portion 15 and the second coupling portion 25 may be made of a magnet or may be configured to include a magnet. For example, the first coupling part 15 may be made of a magnet and the second coupling part 25 may be made of a metal to which a magnet attaches. Conversely, the second coupling part 25 may be made of a magnet and the first coupling part 25 may be made of a magnet. The part 15 may be made of metal.

It is sufficient for the first coupling portion 15 and the second coupling portion 25 to be formed in a structure in which they are coupled to each other, and there is no limit to their shape. For example, when the first coupling part and the second coupling part are magnets, each opposing surface of the first coupling part and the second coupling part may have a planar structure so as to be coupled to each other. Alternatively, as will be described later, the first and second coupling portions may be configured to be coupled in a concavo-convex shape.

Additionally, the first coupling portion and the second coupling portion are not limited to magnets or metal. Any means for coupling and separating the first and second coupling parts from each other is sufficient, and may be formed of, 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 a shoe including a clip 29, and may be configured in various ways, having the same or similar configuration as the clip 19 described above.

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

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

With the wire reel 10 and the wire fixing device 20 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) in Figure 3)

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

After the swing, the first coupling portion 15 and the second coupling portion 25 can be separated by moving the feet with a snap, spreading the 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 wound back into the main body 11.

By using the first and second coupling parts described above, the golfer can draw out the wire to create an alignment line while standing comfortably without bending his waist or using his hands, and the wire can be automatically released by simply releasing the coupling after the swing. can be inserted.

The first coupling portion 15 and the second coupling portion 25 must not only have sufficient coupling strength to allow the wire to be drawn out to form an alignment line, but the coupling must be well maintained. In order to maintain good bonding, it is desirable to structure it so that it cannot be released structurally.

For example, the joined portion of the first coupling portion 15 and the second coupling portion 25 may be made into a concavo-convex structure. As can be seen in FIG. 4, the second coupling portion 25 is configured to have a concave portion 28, and the first coupling portion 15 is configured to have a protrusion, so that the concave portion 28 of the second coupling portion is configured to have a protrusion. It is preferable to configure the protrusion of the first coupling portion 15 to be inserted into. Additionally, 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 part and the second coupling part are coupled by magnetic force, at least one of the protruding part and the concave part may be composed of a magnet. Alternatively, in the first coupling portion and the second coupling portion, the remaining portions excluding the protruding portion and the concave portion may be composed of magnets.

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

Furthermore, it may be considered to maintain good coupling by adjusting the force applied to the wire.

As described above, in a typical wire reel 10, when the wire 13 is pulled out, the tension applied by the reel spring 17 to the wire 13 increases, especially when the wire is pulled out almost to the end, the reel The tension applied by the spring 17 to the wire 13 is maximum. In this case, when the tension applied to the wire 13 exceeds the coupling force of the first coupling part 15 and the second coupling part 25, the coupling of the first coupling part and the second coupling part is not maintained and is separated. A problem arises.

According to one embodiment of the present invention, in order to prevent the above-described problem, that is, to prevent the tension applied to the wire from exceeding the coupling force of the coupling member, a reel spring 17 installed inside the winding drum 16 In relation to this, it is preferable that the width is formed to be smaller at the opposite end area (right side of the enlarged view of FIG. 5) than the portion where the reel spring is fixed in the center (left side of the enlarged view of FIG. 5). For example, the width of the reel spring 17 installed inside the winding drum 16 can be configured to gradually become thinner in a direction away from the centrally fixed portion. Alternatively, in relation to the entire 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 portion at the end farthest from the portion fixed at the center. By reducing the width in this way, it is possible to prevent the tension applied to the wire by the reel spring from greatly increasing when the wire is pulled out. That is, the amount of tension that interferes with maintaining the coupled state of the first coupling portion 15 and the second coupling portion 25 can be reduced.

In this regard, as can be seen in [Table 1] below, the applicant conducted a tension test. Using a spring-type hanging scale, the tension was measured while the wire was pulled out at 10 cm intervals, and finally, the tension was measured when the wire was pulled out to a 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 50 gf) are indicated together.

A: When the reel spring width is 4mm

B: When the width of the reel spring is 3mm for the 10cm length farthest from the center.

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

Additionally, as shown in FIG. 6, graduations or intervals may be displayed on the wire 13. Through this, you can check whether the golfer is standing at the desired stride by looking at the graduations or intervals marked on the drawn wire.

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, this allows the distance between the feet to be easily adjusted during alignment.

Furthermore, the wire 13 is made of nylon and may contain a fluorescent material or a luminous material. Therefore, the fluorescent material can improve identification during the day, and the luminous material allows it to be used at night.

According to one embodiment of the present invention, an LED device can 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 at the bottom of the wire reel 10 or the wire fixture 20. Accordingly, light is radiated 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 manually switched on, or may be configured to be automatically turned on when the first coupling portion 15 and the second coupling portion 25 are coupled. In the latter case, when the first coupling part and the second coupling part are coupled, the switch of the circuit part is automatically turned on, and when the coupling is released, the switch can be configured to 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. It is considered to be within the scope of the claims of the present invention to the extent that anyone skilled in the art can make modifications without departing from the gist of the invention as claimed in the claims.
