A golf tee for preventing breakage and loss

Technical Field The present invention relates to a golf tee, and more particularly, to a golf tee for preventing breakage and loss, whose lower portion is partially stuck in the ground and whose upper portion is provided for placing a golf ball thereon, wherein a portion of the golf tee is separated and bent when a golfer hits a golf ball with a driver, thereby absorbing an impact and preventing a breakage and a loss.

Background Art

In general, a golf tee, which has an upper portion for placing a golf ball thereon and a lower portion to be stuck in the ground, is a small device for placing the golf ball at a fixed height while being stuck in the ground. The golf tee is intended to adjust the height of the golf ball according to natural environments, such as wind or inclination of the ground, or a golfer's characteristics, such as the golfer's condition or body form. Especially, the golf tee is mainly used to send the golf ball away by a driver.

In case of a right-handed golfer, after sticking the golf tee in the ground before the golfer's left foot and placing the golf ball on the top portion of the golf tee, the golfer generally hits the golf ball with a driver. In this instance, due to a loft of a clubface of the driver, as shown in FIG. 1, the golf ball is hit with a little inclination to thereby obtain an advancing power and ascending power.

In this instance, an area of a head portion of the driver is larger than that of the golf ball, and due to the coupling force and the friction force between the golf tee and the golf ball, power is applied to the golf tee at the time of hitting, and so, the golf tee is pulled out from the ground and flies away.

In this case, if the golf tee is not pulled out and firmly fastened in the ground, it acts as resistance to the golf ball and the driver at the time of hitting, and so, it causes a

loss on power applied to the golf ball and a loss on a driver distance of the golf ball. So, to obtain an effective driver distance of the golf ball by reducing the resistance and prevent a breakage of the golf tee, it is good to make the golf tee get bent, or be pulled out or separated according to a hitting direction. Korean Utility Model Registration No. 20-0294422 discloses an improved golf tee, which is separated when a driver hits a golf ball. The golf tee has a spring mounted therein so that the golf tee can be bent to absorb the impact to the maximum when at the time of hitting.

As shown in FIG. 2, the golf tee includes: a main body 1; a height-adjustable seating portion 2 located on the upper portion of the main body 1, and adapted to be bent in an advancing direction of the golf ball; a sticking pin 3 separately formed beneath the main body 1 and elastically connected to the main body 1 through a connection pin 4 and a spring 5; and a small fixing spring 6 mounted at an end of the sticking pin 3.

When the golfer hits the golf ball, the main body is elastically bent and the spring is compressed to thereby absorb the impact, and at the same time, a direction of power is changed to prevent the breakage or pulling-out of the golf tee by impact. In addition, the golf tee can be automatically returned to its original state formed before the hitting by a restoring force of the spring and the connection pin.

However, when the impact is transferred at a rapid speed and tops the compression speed of the spring, the impact is transferred to the golf tee since the golf tee cannot sufficiently absorb the impact.

When a thing, such as a golf club, which transfers power at a rapid speed by the centrifugal force, hits the golf tee, since the spring 5 is accommodated in the inside space of the sticking pin 3 without a spare space, the impact is transferred to the golf tee before the spring 5 is compressed.

So, since the spring 5 cannot perfectly absorb the impact transferred to the sticking pin 3, the sticking pin 3 is pulled out by the impact, and so, the golf tee may be lost.

Furthermore, since the main body 1 is connected to the sticking pin 3 by the connection pin 4 and the spring 5 without the spare space, the impact is directly

transferred to the main body 1. In this instance, the main body 1 is bent and so is not broken, but an end portion of the connection pin 4 located inside the main body may be broken since power, which is not absorbed by the spring, is concentrated on the end portion of the connection pin. Alternatively, the sticking pin 3, which is not bent, may be broken.

So, the golf tee disclosed in Korean Utility Model Registration No. 20-0294422 also cannot sufficiently prevent breakage and loss of the golf tee.

Technical Problem

Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior arts. It is an object of the present invention to provide a golf tee for preventing breakage and loss, which can absorb an impact by a spring and has an upper portion completely separated when a golfer hits a golf ball strongly, thereby preventing a breakage of the golf tee and not having an influence on a driver distance.

It is another object of the present invention to provide a golf tee for preventing breakage and loss, which can change a direction of power applied to the golf tee by the impact generated at the time of hitting and increase a friction force between the golf tee and the ground to prevent the golf tee from being pulled out, thereby preventing a loss of the golf tee.

It is a further object of the present invention to provide a golf tee for preventing breakage and loss, which can automatically return the separated golf tee by virtue of a restoring force of the spring and take a correct posture by a magnet, thereby promoting the return of the golf tee to the original state.

Technical Solution

To achieve the above objects, the present invention provides a golf tee for preventing breakage and loss, which is to fix a golf ball at a predetermined height above the ground, the golf tee comprising: an upper tee 10 having a seating portion 11 for placing the golf ball thereon, an upper receiving space 12 formed therein, and a separation-preventing means 13 disposed inside the upper receiving space; a lower tee 20 having a sticking portion 21 for sticking the golf tee in the ground, a lower receiving space 22 formed therein, and a separation-preventing means 23 disposed inside the lower receiving space; a soft bendable member 30 for connecting the upper tee 10 and the lower tee 20 with each other in such a way that an end of the bendable member 30 is accommodated in the upper receiving space 12 and the other end is accommodated in the lower receiving space 22, the bendable member 30 having upper and lower retaining steps 31 and 32 respectively disposed at both ends thereof, the upper and lower retaining steps 31 and 32 being caught by the separation-preventing means 13 and 23 to thereby preventing separation of the upper tee and the lower tee; a first spring 41 fit around the upper portion of the bendable member and caught by the upper retaining step 31, the first spring 41 being accommodated in the upper receiving space 12 of the upper tee; and a second spring 42 fit around the lower portion of the bendable member and caught by the lower retaining step 31, the second spring 42 being accommodated in the lower receiving space 22 of the lower tee, wherein a free length of the first spring 41 or the second spring 42 is smaller than a vertical length of the upper receiving space 12 or the _s lower receiving space 22, in which the spring is accommodated, to thereby form a sufficient spare space.

Advantageous Effects

The golf tee according to the present invention having the above configuration and operation has the following effects.

First, the sufficient spare space is formed between the first spring 41 and the upper receiving space 12, so that the spring can absorb the impact and the upper tee can be completely separated from the lower tee at the time of hitting.

So, the golf tee according to the present invention can prevent the breakage by sufficiently bending a direction of power and does not have an influence on a driver distance since the upper tee is completely separated from the lower tee to remove resistance to a golf club. Second, since the upper tee 10 is completely separated from the lower tee 20, most of the direction of an ascending power applied to the golf tee by the impact generated at the time of hitting is converted into an advancing power, and a friction force and resistance formed between the golf tee and the ground are increased.

So, the golf tee according to the present invention prevents the loss of the golf tee since the lower tee is not pulled out.

Third, while the separated upper tee 10 is automatically returned by the restoring force of the first spring 41 and the bendable member 30, the golf tee takes a correct posture by a magnetic force between a magnet 15 and a fixing screw 25, so that the upper tee 10 can be seated on the lower tee 20 in stable.

Best Mode for Carrying Out the Invention

(First Embodiment)

A first embodiment of the present invention having the basic configuration of a golf tee is illustrated in FIG. 3.

In FIG. 3, an upper tee 10 includes a seating portion 11 for placing a golf ball on the upper end thereof; an upper receiving space 12 formed therein; and

separation-preventing means 13 disposed inside the upper receiving space 12.

The seating portion 11 is to place and fix the golf ball on the golf tee, and may adopt one of various forms. As a representative form, as shown in FIG. 3, the central portion of the seating portion 11 is hollowed, so that a round-shaped lower portion of the golf ball can be placed on the hollowed portion of the seating portion 11. The seating portion is the most fundamental structure of the golf tee, and has been widely known.

The upper receiving space 12 accommodates a bendable member 30 therein to allow the bendable member 30 to move vertically therein, the bendable member 30 is to bend the upper tee 10 and connect the upper tee 10 with the lower tee 20. The upper receiving space 12 may adopt any one form to allow that the bendable member moves vertically without any resistance. In the first embodiment shown in FIG. 3, the upper receiving space 12 has a cylindrical form.

The separation-preventing means 13 serves to prevent that the bendable member 30 accommodated in the upper receiving space 12 is separated from the upper receiving space 12 when a golfer hits the golf ball. According to the first embodiment of the present invention, FIG. 3 illustrates a jaw, which is the simplest form formed as the separation-preventing means 13. That is, the separation-preventing means 13 is protrudingly formed along the inner surface of the upper receiving space and has the inner diameter smaller than that of an upper retaining step 31 of the bendable member 30. The separation-preventing means 13 and 23 are respectively disposed in the upper receiving space 12 and a lower receiving space 22, and in the first embodiment, the two separation-preventing means 13 have the jaw form. So, in a lower tee 20, the separation-preventing means 13 is protrudingly formed along the inner surface of the lower receiving space 22 and has the inner diameter smaller than that of a lower retaining step 32 of the bendable member 30.

Even though the separation-preventing means 13 and 23 do not take the form shown in FIG. 3, if the separation-preventing means 13 and 23 can prevent separation of the bendable member and provide the above and other characteristics of the present invention, it belongs to the scope of the present invention. The upper tee 10 is made of soft synthetic resin, which has elasticity and is hardly

broken and cut. It is preferable that the upper tee 10 is made of silicon or urethane. Furthermore, combination of silicon and urethane may be also used, and the above materials have been widely known.

In FIG. 3, the lower tee 20 includes a sticking portion 21 formed at the lower portion thereof for allowing the golf tee to be stuck in the ground, the lower receiving space 22 formed therein, and the separation-preventing means 23 disposed in the lower receiving space 22.

The sticking portion 21 is to easily stick and fix the golf tee in the ground. The sticking portion 21 is also the essential part of the golf tee, and may adopt any one of various forms. In the first embodiment, as shown in FIG. 3, the sticking portion 21 has a conical shape having a point at the lower end thereof by getting narrowed downwardly, which is the most basic form.

The lower receiving space 22 is formed inside the lower tee 20, accommodates the bendable member 30 therein, and provides a space to vertically move the bendable member therein. The lower receiving space 22 may adopt any one form, which does not interrupt the movement of the bendable member 30. In the first embodiment, the lower receiving space 22 takes a cylindrical form like the upper receiving space 12.

Description of the separation-preventing means 23 will be omitted since it was previously described in the above. It is preferable that the lower tee 20 is made of hard plastic, which is hard and hardly broken, and generally known materials may be also used.

In FIG. 3, the bendable member 30 connects the upper tee 10 and the lower tee 20 with each other to prevent separation, and has a function to bend the upper tee 10. The bendable member 30 has an end accommodated in the upper receiving space 12 and the other end accommodated in the lower receiving space 22.

The upper and lower retaining steps 31 and 32 having the outer diameters larger than the inner diameters of the separation-preventing means 13 and 23 of the upper and lower receiving spaces 12 and 22 are protrudingly formed at both ends of the bendable member 30, so that the upper tee 10 and the lower tee 20 are not separated from each other by virtue of coupling between the upper and lower retaining steps 31 and 32 and

the separation-preventing means 13 and 23. The upper and lower retaining steps 31 and 32 are formed integrally with the bendable member 30 and made of the same material as the bendable member 30.

The retaining jaws 31 and 32 can adopt any one shape, which can prevent them from being easily separated from the separation-preventing means 13 and 23, and preferably, are formed in a conical shape to enhance convenience in assembly and intensity of coupling.

It is preferable that the bendable member 30 is made of soft synthetic resin, which is easily bendable, keeps elasticity, and is hardly fragile and broken, like the upper tee 10, and particularly, urethane or silicon, hi addition, combination of silicon and urethane may be also used.

A first spring 41 serves to absorb the impact applied to the bendable member 30 and the upper tee 10 and to return the upper tee 10, which is bent after being separated from the lower tee 20, to the original state by a restoring force so that the upper tee 10 can be coupled with the lower tee 20 again.

Furthermore, the first spring 41 also serves to prevent the retaining jaw 31 of the bendable member 30 from being broken due to a sudden collision with the separation-preventing means at the time of hitting. The reason is that the first spring 41 relieves the impact to the retaining jaw 31, on which stress is generally concentrated. The first spring 41 is an elastic body having a turning radius, which is smaller than the outer diameter of the upper retaining step 31 of the bendable member 30 but larger than the inner diameter of the separation-preventing means 13 of the upper tee 10 and the outer diameter of the bendable member 30, and in this embodiment, a cylindrical spring is used. The spring 41 is fit around the upper portion of the bendable member, caught by the upper retaining step 31, and accommodated in the upper receiving space 12 of the upper tee 10.

A second spring 42 serves to absorb the impact applied to the bendable member

30 and the lower tee 20 and to prevent the retaining jaw 32 of the bendable member 30 from being broken by a sudden collision with the separation-preventing means 23 at the time of hitting. As described above, the reason is that the second spring 42 relieves the

impact to the retaining jaw 32, on which stress is generally concentrated.

The second spring 42 is an elastic body having a turning radius, which is smaller than the outer diameter of the lower retaining step 32 of the bendable member 30 but larger than the inner diameter of the separation-preventing means 23 of the lower tee 20 and the outer diameter of the bendable member 30, and in this embodiment, a cylindrical spring is used. The spring 42 is fit around the lower portion of the bendable member, caught by the lower retaining step 32, and accommodated in the lower receiving space 22 of the lower tee 20.

In the first embodiment of the present invention, which has the above configuration, a free length of the first spring 41 is shorter than a vertical length of the upper receiving space 12 such that the golf tee has a sufficient spare space till the impact is applied to the spring 41. Here, the free length means a length in a state where the spring is not transformed since the impact is not applied thereto.

That is, the golf tee according to the first embodiment has a structure that the impact is applied to the first spring 41 located inside the upper tee 10 after the upper tee 10 is separated from the lower tee 20 by sufficiently ascending along the bendable member 30 at the time of hitting.

A characteristic of the first embodiment is the structure related with the upper tee 10 and the first spring 41, and it is to be appreciated that a structure related with the lower tee 20 and the second spring 42 also belongs to the scope and spirit of the present invention.

That is, the golf tee according to the first embodiment of the present invention has the same effect even though a free length of the second spring 42 is shorter than a vertical length of the lower receiving space 22 such that the golf tee has a sufficient spare space till the impact is applied to the spring 42.

(Second Embodiment)

As shown in FIG. 4, the second embodiment of the present invention is characterized in a form of the sticking portion 21 of the lower tee 20. That is, all components excepting the sticking portion 21 are not different from the first embodiment,

but the form of the sticking portion 21 is different from that of the first embodiment. The second embodiment of the present invention is characterized in that a prominent and depressed portion 24 formed on the outer surface of the sticking portion 21.

As an example of the prominent and depressed portion 24, the prominent and depressed portion 24 has at least one concave depressed portion 24-a formed inwardly from the outer surface of the sticking portion 21 in such a way as to extend longitudinally toward an end portion of the sticking portion, and in this instance, the concave depressed portions 24-a are arranged in such a way as to keep regular intervals radially with respect to a central axis of the sticking portion 21. The concave depressed portion 24-a widens a contact area between the golf tee and the ground and compactly accommodates soil in the concave depressed portion 24-a to thereby prevent the golf tee from being easily pulled out due to resistance of the ground or from falling down due to the rotation.

In this embodiment, at least one concave depressed portion 24-a is provided, but in case that at least two concave depressed portions 24-a are provided, it is preferable that the concave depressed portions 24-a are arranged at regular intervals to keep a balance in the entire power.

In FIG. 4, three concave depressed portions are illustrated as an example. The three concave depressed portions are arranged at an angle of 120°, which is the regular interval, radially against the central axis.

As another example of the prominent and depressed portion 24, the prominent and depressed portion 24 has a number of dimples 24-b inwardly formed from the outer surface of the sticking portion 21 in such a way as to be regularly or irregularly arranged on the outer surface of the sticking portion 21. As a further example of the prominent and depressed portion 24, the prominent and depressed portion 24 has a screw thread portion 24-c formed on the outer surface of the sticking portion 21. In this case, the sticking portion 21 can be more easily stuck and more firmly fixed in the ground than those of other examples since the sticking portion is inserted into the ground while being rotated in a rotational direction of the screw thread portion 24-c.

All of the examples of the prominent and depressed portion 24 of the sticking portion 21 mentioned the above provide an effect to prevent that the golf tee is easily pulled out by the resistance of the ground or falls down by the rotation, and are just different from each other in methods for expressing the technical scope of the present invention.

(Third Embodiment)

In the third embodiment of the present invention, the separation-preventing means 13 and 23 disposed in the upper and lower tees 10 and 20. As an example of the third embodiment, the separation-preventing means 13 and 23 have the basic configuration of the first embodiment as shown in FIG. 5, but further includes a female screw thread formed on the inner peripheral surface the lower receiving space 22 of the lower tee 20 and a fixing screw 25 having a male screw thread formed on the outer peripheral surface thereof so as to be screw-coupled to the female screw thread, so that the fixing screw 25 is screw-coupled to the lower tee 20.

The fixing screw 25 has a through-hole formed along a central axis there so as to allow the bendable member 30 to pass through the through-hole. After that, the lower retaining step 32 of the bendable member 30 is caught by the fixing screw 25, so that the bendable member 30 is not separated from the fixing screw 25. The above-mentioned structure provides functions to prevent that the bendable member 30 is easily separated from the lower tee 20 and to make the separation-preventing means 23, which may be structurally weak to the impact, strongly endure the impact in the lower tee 20. In addition, through the above-mentioned structure of the separation-preventing means 23, the bendable member 30 can be easily coupled to the lower tee 20.

As another example of the third embodiment, the separation-preventing means 13 of the upper tee 10 includes a fixing screw 25. That is, the separation-preventing means 13 includes a female screw thread formed on the inner peripheral surface the upper receiving space 12 of the upper tee 10 and a fixing screw 25 having a male screw thread formed on the outer peripheral surface thereof so as to be screw-coupled to the female

screw thread, so that the fixing screw 25 is screw-coupled to the upper tee 10.

(Fourth Embodiment)

In the fourth embodiment of the present invention, a structure to automatically return the separated upper tee 10 to the original state will be described. The structure to automatically return the separated upper tee 10 is configured on the basis of the third embodiment of the present invention.

As an example of the fourth embodiment, as shown in FIG. 6, the fixing screw 25 described in the third embodiment is made of an iron containing material, and the separation-preventing means 13 of the upper tee 10 has in a magnet receiving space 14 formed at the lower end of the separation-preventing means 13. A magnet 15 having a through-hole, through which the bendable member 30 passes, is accommodated in the magnet receiving space 14, so that the separation-preventing means 13 can be coupled with the fixing screw 25 by a magnetic force. Through the above-mentioned structure, the upper tee 10 separated at the time of hitting is moved near a position, where the upper tee 10 was not hit, by virtue of a restoring force by elasticity of the bendable member 30 and the upper tee 10. In this instance, the upper tee 10 is induced to a correct position by a magnetic force to surely seat the upper tee 10 on the lower tee 20. Even though a strong spring is mounted without the above-mentioned structure, the upper tee 10 may be easily returned to the original position by a strong restoring force, but if the spring gets strong, impact applied to the golf tee at the time of the initial hitting is stronger so much, and so, it may cause a breakage or a loss of the golf tee.

As a more preferable example of the fourth embodiment, the separation-preventing means 13 of the upper tee 10 has a retaining jaw protruding in such a way as to cover the magnet. The reason is to protect the magnet in a form of the protruding retaining jaw made of a soft material and to prevent separation of the bendable member 30 from the upper tee 10.

Even though the position of the magnet 15 and the position of the fixing screw 25 in the fourth embodiment may be changed with each other in the upper tee 10 and the

lower tee 20.

That is, the magnet receiving space 14 is formed at the upper end of the separation-preventing means 23 of not the upper tee but the lower tee, and the magnet 15 having the through-hole, through which the bendable member passes, is accommodated in the magnet receiving space, so that the separation-preventing means 23 can be coupled with the fixing screw 25 coupled to the upper tee 10 by virtue of a magnetic force. So, it would be also appreciated that the above structure belongs to the scope of the present invention.

(Fifth Embodiment) hi the fifth embodiment of the present invention, a coupling structure made between the spring and the bendable member to prevent a breakage of the retaining jaw of the bendable member due to impact applied at the time of hitting and to prevent the retaining jaw of the bendable member from being easily separated from the separation-preventing means.

The fifth embodiment is based on the configuration of the first embodiment, and particularly, the second spring 42 is a nonlinear spring having the turning radius getting narrowed downwardly. A diameter of the lower end of the spring 42 is equal to or smaller than the outer diameter of the bendable member 30, so that the lower end of the ^" second spring 42 is fixed to the bendable member 30.

That is, the spiral spring gets narrowed toward an end portion thereof and fixed to the bendable member. Through the above-mentioned structure, at the time of hitting, the spring 42 is not separated from the retaining jaw 32 of the bendable member to thereby relieve the impact by the spring 42 and prevent the bendable member 30, to which the spring is fixed, from being easily separated from the separation-preventing means 23 since the spring 42 having a larger turning radius at the other end portion is caught by the separation-preventing means 23.

Also in the fifth embodiment, the above structure is not restricted to the second spring, and can be applied to the first spring 41.

(Sixth Embodiment)

The sixth embodiment is a combination of the first to fifth embodiments, and, for instance, has a configuration shown in FIG. 7. A detailed description of the sixth embodiment will be omitted since it was previously mentioned in the above embodiments.

Hereinafter, focused on the sixth embodiment, operations of the above embodiments will be described referring to FIG. 8.

First, the golfer sticks the golf tee in the ground, and places the golf ball on the seating portion 11 of the upper tee 10. In this instance, the upper tee 10 and the lower tee 20 are coupled with each other, and particularly, also coupled by the magnet 15.

In addition, the bendable member 30 is not yet bent, and the first spring 41 and the second spring 42 are in a free length state. Particularly, the first spring 41 has a sufficient spare space till before compressed in the free length state since it is shorter than the upper receiving space 12. In the above state, when the golfer hits the golf ball using a driver, a strong impact is applied to the golf ball and the golf tee, and in this instance, in arrow directions shown in FIG. 1 , the applied power obtains an advancing power and ascending power by a loft of the club face of the driver.

The golf tee is bent by the advancing power, and the upper tee 10 is separated from the lower tee 20 by the ascending power.

A separation process of the upper tee 10 will be described. The upper tee 10 is lifted upwardly by the ascending power to thereby ascend in a longitudinal direction of the bendable member 30, and the bendable member 30 is bent by the advancing power, so that the upper tee 10 is finally ascended while being bent. In this instance, the upper tee 10 ascends with no resistance by the spring 41 since there is the spare space due to a difference in the vertical length between the first spring 41 and the upper receiving space 12. When the spare space is entirely exhausted, the upper tee 10 is completely separated from the lower tee 20.

After that, the first spring 41 receives power from the completely separated upper tee 10, and the power is transferred to the lower tee 20 through the bendable member 30.

In this case, the first spring 41 collides to the upper retaining step 31. In this instance, since the impact applied to the retaining jaw 31, on which stress is concentrated, is relieved, the spring 41 collides to the retaining jaw 31 slowly to thereby prevent the breakage of the retaining jaw. Generally, the spring transfers power in a direction of a rotational axis, but since the bendable member is bent, the power applied to the lower tee 20 directs not in an ascending direction but in a direction that the advancing power and the ascending power are combined together, and particularly, the advancing power is increase by a curve.

When the above power is applied, the lower retaining step 32 of the bendable member 30 collides to the fixing screw 25 by ascent of the bendable member 30. But, in this case, the retaining jaw 32 collides to the fixing screw 25 slowly since the impact is relieved by the second spring 42 to thereby prevent the breakage of the retaining jaw 32, and the bendable member 30 is not separated from the fixing screw 25 by virtue of the form of the second spring. Meanwhile, the upper tee 10, which is bent and ascended, collides to the ground when the upper tee 10 is bent to the maximum, and in this instance, most of the ascending power and the advancing power transferred through the bendable member from the upper tee is transferred to the ground and disappeared.

So, when the lower tee 20 receives the advancing power and the ascending power, the lower tee 20 is not pulled out due to a dispersion of power by the collision between the upper tee and the ground, a buffering effect by the spring 42, and a friction force and resistance to the ground by the forms of the sticking portions 24-1, 24-b and 24-c.

In the above state, the upper tee 10 is returned to the original state from the bent state due to the restoring force by elasticity of the bendable member 30, and lowers along the bendable member 30 due to the restoring force of the first spring 41.

The lowering upper tee 10 tends to vibrate by the residual impact, and in this instance, the first spring 41 recovers the free length thereof to thereby have a little influence on the upper tee since the upper receiving space has the spare space again.

The upper tee 10 has a magnetic force by virtue of the magnet 15 mounted therein and the iron fixing screw 25, and then, is seated on the lower tee 20 since the magnet 15

is attached on the fixing screw 25 by the magnetic force.

Through the above process, the operation of the golf tee after the golfer hits the golf ball has been described.
