Description

Golf tee with fine height adjustment {MINUTE HEIGHT ADJUSTABLE GOLF TEE}

The present invention relates to a golf tee capable of fine height adjustment, and more specifically, to a golf tee capable of fine height adjustment that has a structure that allows the height from the ground to be adjusted.

In general, a golf tee is a device that positions the golf ball at a predetermined height from the ground, and is used to increase the distance of the golf ball by minimizing interference from the ground or grass when swinging a driver on a tee shot. Golf tees are widely used not only on the field but also at golf driving ranges.

However, since the grass condition at the tee point is not always even for each hole, golfers must have golf tees of various lengths depending on their height, swing method, grass condition, etc. In other words, it is inconvenient to carry around a set of golf tees with different heights, for example, a short tee, a normal tee, a long tee, etc., and there is a risk of loss.

To solve this problem, a golf tee height adjustment device that can adjust the height of the golf tee has been proposed. The golf tee height adjustment device is disclosed in Patent Document 1 and Patent Document 2.

The golf tee height adjusting device typically includes a driving motor, a lifting part that moves up and down by the driving motor, and a control part that controls the operation of the driving motor to adjust the lifting height of the lifting part. The golf tee height adjusting device has the advantage of being able to automatically adjust the height of the golf tee, but has a problem in that it has a complicated structure and is very expensive, and requires separate construction to be installed in an existing golf driving range.

As another alternative, Patent Document 3 includes a golf ball support portion for supporting a golf ball, a body portion formed on a lower surface of the golf ball support portion and extending downward, and a body portion formed on the lower side of the body portion to be driven into the ground. A golf tee capable of fine height adjustment was proposed, including a wedge and a plurality of height adjustment grooves formed on the body in the height direction.

However, the golf tee disclosed in Patent Document 3 is used because when adjusting the height, the coupling part must be moved along the guide groove to separate it from the height adjustment plate, and then the coupling portion at another position among the plurality of height adjustment grooves must be reinserted into the guide groove of the height adjustment plate. This has the disadvantage of being cumbersome and difficult to adjust quickly. In addition, since the height adjustment interval is related to the thickness of the height adjustment plate, if the height adjustment interval is finely configured, the thickness of the height adjustment plate becomes too thin, making it difficult to secure rigidity.

Patent Document 1: Registered Utility Model Publication No. 20-0197142 (registered on July 10, 2000) Patent Document 2: Registered Utility Model Publication No. 20-0199143 (registered on July 28, 2000) Patent Document 3: Publication of Patent No. 10-2022-0141215 (October 19, 2022, published)

The present invention was created in consideration of the above points, and its purpose is to provide a golf tee that allows fine height adjustment in addition to height adjustment by the support itself.

Another object of the present invention is to provide a golf tee with a structure that allows the fine height adjustment bar to be used as a short tee.

In order to achieve the above object, the present invention provides a support pole having a head portion, a body portion extending downward from the head portion in a bar shape, and a tip portion formed at the end of the body portion and capable of being driven into the ground; and a fine height adjustment bar that is assembled to the support and can be raised and lowered in the axial direction of the support and has a mounting portion at the top on which a golf ball can be mounted. It provides a golf tee capable of fine height adjustment, including a bar.

Additionally, it may further include a height plate fastened to the support.

The fine height adjustment bar may be a shorty provided with a tip that can be driven into the ground.

The shorty may be made of PLA (Poly Lactic Acid) plastic or biodegradable material.

The shorty may be inserted into a central hole formed in the upper center of the head portion.

The shorty has elasticity, and circular protrusions are provided on the outer peripheral surface of the shorty at regular intervals in the longitudinal direction, and the circular protrusions are press-fitted into the central hole, so that the finely adjusted height can be fixed.

The body portion of the support may further include a plurality of height adjustment grooves formed at predetermined intervals in the height direction.

The golf tee capable of fine height adjustment according to the present invention has the following effects.

First, precise height adjustment is possible through height adjustment according to the depth at which the tip of the prop is driven into the ground and fine height adjustment using the fine height adjustment bar installed at the top of the prop.

Second, with the strut inserted into the coupling groove of the height adjustment plate, the prop is moved in the longitudinal direction to select an appropriate tee height that can respond to the ground conditions at the tee shot point, and then the prop is raised horizontally and the plate is fastened with one touch to quickly adjust the height. and can be fixed.

Third, it can be carried with the height adjustment plate and support installed, preventing loss while moving.

Fourth, it is highly portable because the golf tee can be worn on the user's waistband by utilizing the long hole provided in the height adjustment plate.

Fifth, a structure that can hold a fine height adjustment bar (shorty) can be provided on a part of the height plate. Accordingly, the functions of two golf tees (for example, a normal tee and a short tee) with different heights can be implemented in one golf tee.

Sixth, if the fine height adjustment bar also functions as a short tee, it can be used for short distance tee shots, so it can support tee shots of virtually any distance.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

1 is a side view of a golf tee capable of fine height adjustment according to a preferred embodiment of the present invention.

Referring to FIG. 1, a golf tee capable of fine height adjustment according to a preferred embodiment of the present invention includes a strut 10 with a plurality of height adjustment grooves 13 formed in the height direction, and a head portion 11 of the strut 10. ) includes a fine height adjustment bar 30 installed to enable height adjustment.

The support 10 includes a head portion 11 on which a golf ball can be placed, a body portion 12 located below the head portion 11, and an end portion of the body portion 12, which is formed on the ground. It is provided with a tip portion 14 that is driven into the body portion 12, a plurality of height adjustment grooves 13 formed at predetermined intervals in the height direction, and a coupling portion 12a formed by the height adjustment grooves 13.

The head portion 11 may have an upper part in an upper-lower narrow shape and a lower part in a cylindrical shape. Protrusions 11a may be disposed around the top of the head 11 at predetermined intervals to prevent unnecessary movement of the golf ball raised.

The body portion 12 is configured in the form of a bar extending downward from the head portion 11. The body portion 12 can be detachably assembled to the head portion 11 by screwing or press fitting. Alternatively, the body portion 12 may be formed integrally with the head portion 11. The outer peripheral surface of the body portion 12 may be polygonal or cylindrical in shape.

The body portion 12 and the tip portion 14 may preferably be constructed as one piece, or alternatively may be constructed as separate pieces.

A plurality of height adjustment grooves 13 are formed on the body portion 12 at predetermined intervals in the height direction. The spacing between the plurality of height adjustment grooves 13 becomes the height adjustment unit of the support 10. For example, if the height adjustment grooves 13 are formed at 5 millimeter (mm) intervals on the body 12 of the strut 10, the height from the ground to the top of the strut 10 can be adjusted in 5 millimeter (mm) increments. possible.

The coupling portion 12a is the innermost part of the height adjustment groove 13 and is selectively coupled to the fixing hole 23 formed in the height plate 20. Here, the outer diameter of the coupling portion 12a is preferably smaller than the outer diameter of the body portion 12. If the outer circumferential shape of the coupling portion 12a is also polygonal (e.g., hexagonal) in response to the outer circumferential shape of the body portion 12, closer coupling between the strut 10 and the height plate 20 is possible. There is an advantage. More preferably, the periphery of the inner wall around the hole forming the coupling portion 12a and the fixing hole 23 may also have a polygonal (eg, hexagonal) shape.

The fine height adjustment bar 30 is inserted into a central hole formed in the center of the head portion 11 of the support 10 and is installed to be able to be raised and lowered in the axial direction. A mounting portion 31 on which a golf ball can be mounted is provided at the top of the fine height adjustment bar 30. The fine height adjustment bar 30 is made of an elastic synthetic resin material, and a plurality of circular protrusions 32 are provided on the outer peripheral surface of the fine height adjustment bar 30 at regular intervals in the longitudinal direction, and the circular protrusions 32 are By being press-fitted into the central hole, the finely adjusted height can be fixed. In other words, the spacing between the plurality of circular protrusions 32 formed on the fine height adjustment bar 30 becomes the height adjustment unit of the fine height adjustment bar 30. For example, when the circular protrusions 32 are formed at intervals of 4 millimeters (mm) on the fine height adjustment bar 30, the distance from the top of the head portion 11 of the support 10 to the top of the fine height adjustment bar 30 The height can be adjusted in 4 millimeter (mm) increments. In this way, the spacing between the plurality of circular protrusions 32 formed on the fine height adjustment bar 30 is formed to be smaller (closer) than the spacing between the height adjustment grooves 13 formed on the body portion 12 of the support 10. Fine height adjustment is possible. Figures 1 (a) to (c) show an example of finely adjusting the height to a lower level by gradually pushing the fine height adjustment bar 30 harder.

Figure 2 is a perspective view showing the appearance of a golf tee capable of fine height adjustment according to another embodiment of the present invention, and Figure 3 is a side view of Figure 1.

Referring to Figures 2 and 3, a golf tee capable of fine height adjustment according to another embodiment of the present invention includes a strut 10 with a plurality of height adjustment grooves 13 formed in the height direction, and the head of the strut 10. It includes a fine height adjustment bar 30 installed on the part 11 to enable height adjustment, and a height plate 20 that is inserted into the support 10 and fixes the height of the golf tee.

The support 10 can be adjusted in height by moving forward and backward in the axial direction (longitudinal direction) while accommodated in the coupling hole 22 of the height plate 20, and the coupling portion 12a is inserted into the fixing hole 23. The height from the ground to the top is fixed. Specifically, in Figure 4, as the height plate 20 moves away from the support 10 by the user's manipulation, the body portion 12 of the support 10 is separated from the fixing hole 23 and the coupling hole ( 22), and in this state, an example is shown in which the support 10 is relatively lowered and the height is adjusted to a lower level.

The height plate 20 is fastened to the height adjustment groove 13 of the strut 10 and serves to fix the height from the ground at the tee shot point to the top of the strut 10. Preferably, the height plate 20 is configured in a directional shape (for example, the front portion is relatively sharp) so that it also functions as an aiming plate for aiming during golf.

As shown in Figure 5, the height plate 20 has a coupling hole 22 having an inner diameter larger than the outer diameter of the body portion 12, and is in communication with the coupling hole 22 and has an inner diameter compared to the coupling hole 22. This small fixing hole (23), a first long hole (24) extending long inward from the edge of one side of both sides of the body, and a second long hole (25) extending long inward inward from the edge of the other side of both sides of the body. ) is provided. In order to neatly arrange each component and maximize space utilization efficiency, the first long hole (24), coupling hole (22), fixing hole (23), and second long hole (25) pass through the center of the height plate (20). Can be arranged in a straight line.

The coupling hole 22 and the fixing hole 23 are arranged adjacent to each other and in contact with each other. That is, the coupling hole 22 and the fixing hole 23 communicate with each other to form one large hole overall, including a portion with a relatively large inner diameter on one side and a relatively small inner diameter on the other side. Therefore, as shown in (a) of FIG. 5, the body portion 12 of the strut 10 is raised in a state accommodated in the coupling hole 22 and the base plate 20 is moved in the axial direction (longitudinal direction) of the strut 10. The height of the support 10 can be adjusted by moving it forward and backward (or up and down). In addition, after selecting the height adjustment groove 13 corresponding to the desired height, as shown in (b) of FIG. 5, the height plate 20 is moved in the transverse direction of the support 10 to connect the coupling portion 12a. The height can be fixed by fitting into the fixing hole (23).

The first long hole 24 has a shape cut by a predetermined length from one edge of the height plate 20. The first long hole 24 communicates with the coupling hole 22, thereby providing elasticity and elasticity to the fixing plate body 21.

The second long hole 25 has a shape cut by a predetermined length from the edge edge of the other side (opposite side) of the height plate 20. The second long hole 25 provides a user wearing portion that can be fitted with the user's waist band, etc. to attach the golf tee to the user's body to increase portability.

The first long hole 24 and the second long hole 25 may be formed simultaneously with the formation of the fixing plate body 21, for example, in the process of plastic injection molding the height fixing plate 20.

The reinforcing protrusion 26 protrudes to extend along the edge of the second long hole 25 to increase the durability of the height plate 20. That is, when wearing the user's waist band, etc. by fitting it into the second long hole 25 of the height plate 20, even if tension is applied to both sides of the second long hole 25, the height plate 20 is not easily split. It works. Among the reinforcing protrusions (26), the portion corresponding to the innermost part of the second long hole (25) has a protruding extension (see 26a in FIG. 8) that contacts a designated part of the body portion (12) in the direction of the fixing hole (23). It is formed to protrude to a certain length. The protrusion extension portion 26a further improves the tensile strength of the elevation plate 20 and can also serve as a stopper that limits the contact strength between the elevation plate 20 and the support column 10 to an appropriate level.

6 to 8 show examples of the use of golf tees capable of fine height adjustment. As shown in Figure 6, the golf tee can be used to position the golf ball 1 at a predetermined height from the ground at the tee shot point. Although not shown in the drawing, the support 10 maintains a vertical position by having the lower tip portion 14 embedded in the ground at the tee shot point.

If you want to adjust the height of the golf tee, raise the body portion 12 of the strut 10 to be accommodated in the coupling hole 22 and move the top plate 20 as shown in (a) of FIG. 7. ), the height of the support 10 can be appropriately adjusted by moving it forward and backward (or up and down) in the axial direction (longitudinal direction). At this time, height adjustment can be performed, for example, by moving up and down in units of 5 millimeters (mm).

After selecting the height adjustment groove 13 corresponding to the desired height, raise it as shown in (b) of Figure 7 and move the top plate 20 in the transverse direction of the support 10 to attach the coupling portion 12a to the fixing hole 23. The adjusted height can be firmly fixed by fitting together.

In addition, for example, if you want to slightly increase the height of the golf tee, gently pull the fine height adjustment bar 30 at the top of the head part 11 of the strut 10 as shown in FIG. 8 to finely adjust the height to the desired height. Just adjust it. At this time, fine height adjustment can be performed, for example, by moving up and down in units of 4 millimeters (mm).

Figure 9 is an exploded perspective view showing the appearance of a golf tee capable of fine height adjustment according to another embodiment of the present invention, Figure 10 is a plan view of the raised plate in Figure 9, and Figure 11 is a raised plate on the support in Figure 9. This is a perspective view showing this combined state.

Referring to FIGS. 9 to 11, a golf tee capable of fine height adjustment according to another embodiment of the present invention includes a strut 10 having a plurality of height adjustment grooves 13 formed in the height direction, and a strut 10. A height plate 20 that is inserted to fix the height of the golf tee, and a fine height adjustment bar 30' that is removably inserted into the head part 11 of the strut 10 and can be raised and lowered in the axial direction and has a tip portion at the bottom. ) includes.

As shown in Figures 11 and 12, the coupling hole 22 and the fixing hole 23 are arranged adjacent to each other. That is, the coupling hole 22 and the fixing hole 23 communicate with each other to form one large hole overall, including a portion with a relatively large inner diameter on one side and a relatively small inner diameter on the other side. Here, whether the inner diameter is relatively large or small can be defined by whether the body portion 12 of the strut 10 can pass in the axial direction. That is, when the body portion 12 of the strut 10 is accommodated in the coupling hole 22 and the height plate 20' is moved forward or backward (or up and down) in the axial direction (longitudinal direction) of the strut 10, The height of the support 10 can be adjusted. In addition, after selecting the height adjustment groove 13 corresponding to the desired height, the height plate 20' is moved in the transverse direction of the support 10, and the coupling portion 12a is fitted and coupled to the fixing hole 23. The height can be fixed. At this time, the coupling hole 22 and the fixing hole 23 may be formed by a pair of elastic arms 40 arranged substantially in a pincer shape. It is preferable that the pair of elastic arms 40 include a portion of the inner wall of the fixing hole 23 that is bent to correspond to a polygon (eg, hexagon). In this case, the body portion 12 of the support 10 is elastically fitted into the fixing hole 23, so there is an advantage that it is not easily separated.

The fine height adjustment bar 30' is provided with a mounting portion 31 provided at the top of the body portion to enable mounting of the golf ball 1, and a tip portion 33 provided at the bottom of the body portion so that it can be selectively driven into the ground. . At least one circular protrusion 32 is provided on the outer peripheral surface of the fine height adjustment bar 30 at regular intervals in the longitudinal direction, and the circular protrusion 32 is press-fitted into the center hole at the top of the support 10 to finely adjust the height. can be fixed.

The fine height adjustment bar 30' can actually function as a shorty by being driven into the ground through the tip part 33 at the end of the body. As shown in Figure 9, the length of the fine height adjustment bar 30' is significantly shorter than the length of the support in order to function as a shorty. In addition, a shorty mounting hole 27 is provided on a part of the height plate 20, which allows the fine height adjustment bar 30' to be separated from the support 10 and placed fixedly on the ground. Specifically, the shorty mounting device 27 is configured to have a concave shape that is recessed by a predetermined area from one edge of the height plate 20. A circular groove 29 may be formed on the inner wall of the shorty mounting hole 27 into which the circular protrusion 32 of the fine height adjustment bar 30' can be inserted. Therefore, the fine height adjustment bar 30', that is, the shorty, can be used independently by being driven into the ground and fastened to the shorty mounting device 27 at the required height, as shown in FIG. 13. Here, the height from the height plate 20' to the top of the shorty can be conveniently adjusted by selecting the circular protrusion 32 fitted into the shorty mounting hole 27 among the plurality of circular protrusions 32. In this case, there is an advantage in that one golf tee can implement the functions of two golf tees (for example, a normal tee and a short tee) with different heights.

The fine height adjustment bar (30'), or shorty, may be made of PLA (Poly Lactic Acid) plastic or various other biodegradable materials. In this case, even if the shorty is lost, it decomposes naturally, which has the advantage of being eco-friendly.

The second long hole 25 has a shape cut by a predetermined length from the edge of the other side (opposite side) of the height plate 20'. The second long hole 25 provides a user wearing portion that can be fitted with the user's waist band, etc. to attach the golf tee to the user's body to increase portability. The shorty mounting hole 27 and the second long hole 25 may be formed simultaneously with the formation of the fixing plate body 21, for example, in the process of plastic injection molding the height fixing plate 20'. In order to neatly arrange each component and maximize space utilization efficiency, the shorty mounting hole (27), coupling hole (22), fixing hole (23), and second long hole (25) are raised and pass through the center of the top plate (20). Can be arranged in a straight line.

In a portion close to the entrance of the second long hole 25, at least two or more protrusions 28 may be formed to alternate with each other. When carrying a golf tee, that is, when the split portion of the second long hole 25 is fitted into a waist band, pocket, ring, etc., the protrusion 28 prevents the golf tee from being lost due to separation due to the user's walking or other movement. .

As described above, the golf tee capable of fine height adjustment according to the present invention can be finely adjusted using the fine height adjustment bar (30, 30') mounted on the upper part of the strut (10), and when a short tee is needed, the fine height adjustment is possible. It is convenient to use the height adjustment bar (30, 30') as a shorty by detaching it from the support (10) and inserting it into the ground.

Although the present invention has been described above with limited examples and drawings, the present invention is not limited thereto and can be understood by those skilled in the art in the technical field to which the present invention belongs within the scope of equivalents of the technical idea of the present invention. Of course, various modifications and variations are possible.
