Description

  The present invention relates to a golf tee that can reduce the resistance at the time of hitting as much as possible and can be easily pierced into the ground with a golf ball placed thereon.

In golf play, when the first shot is shot, a ball is placed on the golf tee and shot, but many conventional golf tees have a leg portion with a sharp tip and a top portion on which the ball is placed. It was used. However, in this type of golf tee, when the ball is hit, there is a problem that resistance is generated on the contact surface between the tee and the ball, and the flying distance is reduced accordingly.

  Therefore, in recent years, in order to reduce the resistance of the contact surface between the ball and the golf tee, a strut having a diameter of about 1 to 2 mm on the top surface on the top surface, such as the golf tee 100 shown in FIG. Golf tees that can be hit in a state in which about 6 to 8 pieces of 101 are formed and a ball is placed on the column have been developed and marketed. The area of the tip of the support that comes into contact with the ball is very small, so the ball and the golf tee have become point contact from the conventional surface contact, and the resistance generated on the contact surface between the ball and the golf tee is greatly increased. Reduced to As described above, various golf tees that can reduce the resistance and extend the flight distance by supporting the golf ball with a point instead of a surface have been devised, and numerous patent applications including utility models 1 to 3 and utility model registration applications have been filed. ing.

In Patent Document 1, a piercing portion to the ground, a ball mounting portion provided on the upper portion of the piercing portion, and a plurality of pieces integrally provided radially in plan view on the upper portion of the ball mounting portion to support the ball. A “golf tee” is disclosed that includes a post having a flexible support piece. This “golf tee” is intended to realize two points, that is, the resistance at the time of hitting is reduced as much as possible and that the ball can be easily pushed into the ground. For this purpose, eight ribs are integrally formed on the outer peripheral surface of the ball mounting portion, and a column group is formed on the upper portion of the ball mounting portion. Each rib has a thin upper portion and serves as a support piece for the ball at the time of hitting. Since it supports in the state which floated from the ball | bowl mounting part, the friction and hit | damage resistance of a tee and a ball at the time of hitting a ball are reduced. Also, when the ball is placed on the support piece and the ball and the ball placement portion are gripped, the support piece spreads when the piercing portion is pierced into the ground, but the spread is caused by the ball contacting the upper surface of the ball placement portion. Be constrained. Thereafter, when the hand is released, the ball is supported in a state of floating from the ball mounting portion by the support piece having a high restoring force.
By the way, if the struts on which the balls are placed are short and thick, there is resistance during shots, so thin and long struts are desired. The length of the support was limited to around 5 mm. In fact, most commercially available golf tees are about 4-5 mm. On the other hand, the current situation is that golf clubs having a large-sized head part whose volume exceeds 460 cc have been released one after another. This is because although the upper limit of the volume is defined as 460 cc in the golf rules, the upper limit may be exceeded in private golf other than the official competition. In order to cope with such an increase in the size of the head, in order to capture a golf ball with the core of the club, the length of the support is ideally 10 mm or more. In this regard, the integral molding described in Patent Document 1 requires a complicated and ultra-precise mold, and cannot meet the demand of 10 mm or more in terms of cost.

Patent Document 2 includes a fixed member formed of a hard material and a movable member formed of a soft material, and has a ball support portion in which the upper end portion of the movable member is divided into a plurality of support columns. A “golf tee” having a concave curved ball contact surface at the upper end of the member is disclosed.
When this golf tee is inserted into the ground via the ball, it can be inserted smoothly and easily by applying downward pressure to the ball while pushing the ball support portion and contacting the ball against the ball contact surface. . However, even during the tee shot, the ball is in contact with not only the ball support portion but also the ball contact surface (see FIG. 7). In other words, since the ball contact surface is always in contact with the ball, it becomes a resistance at the time of hitting and the flight distance is reduced. In order to reduce this resistance, at the time of a tee shot, the fixed member and the movable member are slid so that the ball is supported only by the ball support portion as much as possible. However, having such a mobility results in a complicated structure and is not suitable for practical use of an inexpensive product such as a golf tee. Further, since the golf tee described in Patent Document 2 is integrally formed with a support for supporting the ball at the time of a tee shot in the same manner as the golf tee described in Patent Document 1, a support having a length of 10 mm or more due to the restriction of the mold. It is difficult to realize.

  In Patent Document 3, a plurality of flexible struts are integrally provided on the upper part of the ball, and the golf ball is supported by the struts in a floating state, and a plurality of struts are also provided inside the struts. A “golf tee” is disclosed in which the bottom side of a golf ball is supported by an inner column. That is, when a ball is placed on the tee for a tee shot, the ball is stably supported by the outer support column and the inner support column in a stable state. However, since the ball is also in contact with the plurality of support columns on the inner side, the resistance at the tee shot is generated correspondingly, and the flight distance is reduced. As a countermeasure for this, the ball mount is slid upward using the impact of the tee shot so that the ball is supported only by the outer column, but the resistance with the inner column is completely eliminated. It is difficult and is not suitable for practical use as in Patent Document 2. Moreover, since the outer support | pillar is integrally molded similarly to patent document 1 and patent document 2, it is difficult to implement | achieve the support | pillar of length 10 mm or more.

JP 2004-254961 A JP 2007-130339 A JP 2007-301267 A

In view of the problems as described above, it is an object of the present invention to provide a golf tee provided with “thin and long struts” that can greatly reduce resistance during a shot and can cope with an increase in the size of a golf head. By the way, “thin and long struts” come with difficult problems. In other words, when a golf tee is inserted into the ground, many people operate with the ball placed on the support, and if the force to pierce the golf tee is applied to the support through the ball, the support cannot be restored. The problem is that there is a risk of deformation. To prevent this, conversely, it must be a "thick and short support". Another object of the present invention is to solve this contradictory request in a form that can be realized.

In order to achieve the above object, the golf tee of the invention according to claim 1 provides:
It has a tee body and a pedestal that allows the column to pass through.
The tee body is composed of a leg portion having a sharp tip and a pedestal receiving portion that fits the pedestal portion,
The struts are arranged at equal intervals on the outer circumference of two concentric circles centered on the center of the pedestal portion, and a plurality of outer struts made of a flexible and strong material, and on the inner circumference. There are inner struts arranged and lower in height than the outer struts, and the outer struts and the inner struts are separate bodies,
The pedestal part has a fitting hole for fitting the pedestal receiving part of the tee body in the center part, and a pillar through hole for inserting the outer pillar and the inner pillar,
When a golf ball is shot, the golf ball floats from the tip of the inner column and is placed on the tip of the plurality of outer columns. When the legs are pierced into the ground, almost no pressure is applied to the outer column. Without applying, the golf ball is pressed against the tip of the inner support and a downward force is applied through the golf ball.

  In the golf tee of the present invention, since the outer support column and the inner support column are separately formed, different materials that match the functions of the outer support column and the inner support column can be used, or different shapes can be used. If the outer strut and the inner strut are integrally molded, the outer strut could not be lengthened due to the structure of the mold and the strength of the inner strut required when piercing into the ground. However, according to the present invention, this problem can be solved by independently forming a support (inner support) for supporting the ball only when the tee is inserted into the ground, and a support (outer support) for only placing the ball during a shot. The point was solved. As a result, thin and long struts that could only be realized with a conventional brush-shaped resin golf tee can be set with a desired fineness, length, and shape.

According to a second aspect of the present invention, in the golf tee according to the first aspect, each of the plurality of outer struts has a ball support portion that is tapered toward the tip and is inclined outward toward the axis of the tee body. A large-diameter column base is integrally formed, and the column through-hole opening on the lower bottom side of the pedestal has a base accommodating portion for accommodating the column base.
In this way, since it is only necessary to form a plurality of outer struts one by one, it is possible to make the struts longer than before. Conventionally, when forming 6 to 8 curved struts at the same time, it was impossible to realize a long strut because of the structure of the mold. This makes it possible to make the length ideal for a golfer (10 to 15 mm). This is 2 to 3 times longer than conventional strut-type golf tees, and even if the golf ball hits with a larger club head, the club head will not hit the tip of the outer tee of the golf tee. It can be hit with the same feeling as hitting a golf ball placed on turf grass. Furthermore, since the area of the tip portion of the outer support is small, even if a golf ball is placed, the contact resistance is reduced and the flight distance is not reduced.
In addition, each outer support is thinner toward the tip, that is, the base is thicker, so even if a golf ball is placed, it does not easily fall down, and each outer support is inclined to the outside, so it can support the ball in a wide range The golf ball can be stably supported even with a small number of around eight.

According to a third aspect of the present invention, in the golf tee according to the first aspect, the outer support column is narrowed toward the tip at a strip-shaped support base and an upper end of the support base, and the support base is cylindrical. A plurality of ball support portions that are sometimes inclined outwardly are integrally formed, and the cylindrical support base is received in a base support provided in the support through-hole opening on the lower bottom surface side of the pedestal. The ball support portions are inserted into the support through holes.
In Claim 2, the outer support columns are formed one by one. However, in Claim 3, a plurality of outer support columns are integrally formed. In the case of integrally molding a three-dimensional support column due to restrictions on the mold, etc., there was a limit to the length of the support column. It is possible to make it sufficiently long. In addition, labor and time for mounting the outer support to the pedestal are reduced, which is advantageous in terms of cost.

According to a fourth aspect of the present invention, in the golf tee according to the first aspect, the inner strut is made of a flexible and tough material, and is narrowed toward the tip and inclined outward toward the axis of the tee body. A base support portion that includes a plurality of support posts integrally formed with a ball support portion and a large-diameter support base, and that stores the support base in the support through hole opening on the lower bottom side of the pedestal. It is characterized by having.
Since the inner support is separate from the outer support, only the following two points need be considered. That is, it is to provide a performance capable of withstanding the pressure applied through the golf ball during tee insertion, and to make the length shorter than the outer support so as not to touch the golf ball during a shot.
The inner strut of claim 4 meets these conditions.

According to a fifth aspect of the present invention, in the golf tee according to the first aspect, the inner strut is made of a flexible and tough material, and is narrowed toward the tip at the strip-shaped strut base and the upper end of the strut base. And a plurality of ball support portions that are inclined outward when the support base is formed into a cylindrical shape, and the support base that is formed in a cylindrical shape is formed in the support through hole opening on the lower bottom side of the pedestal It is accommodated in the base accommodating part provided in this, Each said ball support part is penetrated by the said support | pillar through-hole.
In Claim 4, the inner struts are formed one by one, but in Claim 5, the plurality of inner struts are integrally formed. In the case of integrally molding a three-dimensional column due to restrictions of the mold, etc., there was a limit to the length of the column, but in claim 5, since it is three-dimensionalized after first integrally molded in a flatly developed state, This saves time and labor when mounting the inner strut to the pedestal, which is advantageous in terms of cost.

According to a sixth aspect of the present invention, in the golf tee according to the first aspect, the inner strut is made of a hard and strong material, and has a thin ball support portion that stands substantially upright on the upper bottom surface of the pedestal portion, and a large It is composed of a plurality of struts integrally formed with a strut base having a diameter, and the base through-hole opening on the lower bottom side of the pedestal portion has a base accommodating portion for accommodating the strut base. To do.
Thus, by using a hard and strong material for the inner strut unlike the outer strut, it is not necessary to increase the thickness from the tip to the root as in the golf tee of claim 4, and the shape is thin and straight. Can be adopted.

According to a seventh aspect of the present invention, in the golf tee according to the first aspect, the inner support column is connected to a ball support portion having a substantially rectangular cross section perpendicular to the axis of the tee body, and a lower portion of the ball support portion. It is composed of a plurality of struts formed from a strut base to be provided, and the strut through hole opening on the lower bottom side of the pedestal portion has a base accommodating portion for accommodating the strut base.
One strut is plate-shaped (the cross section may be curved in an arc shape) and wide, so it makes line contact with the ball. Therefore, the number can be reduced as compared with the inner support column having a small area at the tip.

According to an eighth aspect of the present invention, in the golf tee according to the first aspect, the inner support column includes a cylindrical ball support portion and a support base portion provided at a lower end portion of the ball support portion. The ball support portion is divided into one or more ball support pieces by one or more notches, and the support base is provided in the support through hole opening on the lower bottom side of the pedestal. The ball support piece is inserted into the support through hole.
As described above, the inner support column is substantially cylindrical, so that the mold can be easily manufactured and can be easily mounted on the pedestal.
Further, even if the ball support portion is divided into a plurality of ball support pieces, the base portions of the support pieces are connected to each other, so that it is easy to mount on the pedestal portion.

According to a ninth aspect of the present invention, in the golf tee according to the first aspect, the outer strut has a length of approximately 10.0 to 12.0 mm protruding from the pedestal portion, and the front end portion of the inner strut Is characterized by being approximately 1.5 to 4.0 mm below the tip of the outer support.
In this way, the length of the inner support is made shorter than that of the outer support so that the golf ball placed on the tip of the outer support during the tee shot does not contact the inner support. Therefore, resistance between the golf club and the inner support does not occur, and the flight distance does not decrease. That is, the inner support column is provided only for applying pressure when the tee is inserted into the ground.

The outer strut and inner strut are separated, and the outer strut is specialized for the function of simply placing a ball when shot, and the inner strut is specialized for the function of receiving pressure when the golf tee is stabbed into the ground. It was. As a result, the outer strut can be made longer and thinner than before, so that it is possible to provide a golf tee that enables a shot with almost no resistance. In addition, since the ball does not even contact the inner support during a shot, there is no resistance that reduces the flight distance.
Furthermore, since both the outer support column and the inner support column are simply inserted into the pedestal portion, and the pedestal portion is fitted into the tee body, it does not require skilled work for manufacturing and can be provided to the customer at a low cost.

[First Embodiment]
A golf tee 1 according to a first embodiment of the present invention will be described with reference to the drawings.
In the following description, “upper” when expressing “upper” or “upper surface” refers to the upper side of the function of the golf tee. That is, a golf tee is used by piercing one end on the ground or turf and placing a golf ball on the other end, but in the following description, the side on which the golf ball is placed is “up” and the side that is pushed into the ground Is expressed as “below”.

  As shown in FIGS. 1 and 2, the golf tee 1 includes a tee body 2, a plurality of pillars 3 that support a golf ball, and a pedestal portion 4 that has a pillar through-hole through which the pillar 3 is inserted. .

The tee body 2 is integrally formed with a lower leg portion 21 and an upper pedestal receiving portion 22.
The lower end of the leg 21 is tapered so that it can be easily stabbed into the ground or grass.
As shown in FIGS. 2 and 3, the pedestal receiving portion 22 includes a pedestal placement surface 221 on which the pedestal portion 4 is placed, and a protrusion 222 protruding upward from the pedestal placement surface 221. A fitting portion 223 is provided between the protruding portion 222 and the base mounting surface 221. In addition, a hollow portion 224 that opens to the upper end of the protruding portion 222 is formed inside the tee body 2. The hollow portion 224 can reduce the weight of the tee body 2 and can absorb unnecessary force applied when the tee body 2 is fitted into the pedestal portion 4.
As the material of the tee main body 2, a strong tree, various synthetic resins, and the like are appropriate because the leg portion 21 is inserted into the ground or the like.

  A plurality of support columns 3 are attached to the pedestal portion 4. There are two types of struts 3, an outer strut 3A and an inner strut 3B that have different functions and materials. Thus, the provision of two types of struts is a major feature of the golf tee according to the present invention.

As shown in (1) of FIG. 4, the outer support 3A is integrally formed with a support base 32A and a ball support 31A that narrows upward from the support base 32A. The diameter of the tip portion of the ball support portion 31A is about 0.7 mm, and the diameter of the root portion is about 1.4 mm. The golf ball is supported by the tip portions of the eight outer struts 3A at the time of teeing up. However, since the area is extremely small, the golf ball is supported by the golf tee 1 in a point contact state. The length of the ball support portion 31A protruding from the pedestal portion 4 is 10.0 to 12.0 mm, and the golf ball can be supported at an ideal height for the golfer.
The support base portion 32A has a larger diameter than the base portion of the ball support portion 31A for preventing the base portion 4 from coming off, and a diameter of about 2 mm is appropriate. The shape of the support base 32A is not limited to the disk shape as shown in FIG. 3, but may be a tapered shape with a tip that is nearly flat.
For the outer support 3A, a synthetic resin or the like that is sufficiently strong even if it is thin, has a strong restoring force from deformation, and has high flexibility is suitable. This is because it is desired that the golf ball does not break when it is placed, can be immediately restored to its original state even if it is deformed by the weight of the golf ball, and it is less resistant even when hit by a golf club.

As shown in (2) of FIG. 4, the inner column 3B is integrally formed with a column base 32B and a ball support 31B that becomes thinner from the column base 32B upward. The diameter of the tip of the ball support portion 31B is about 0.7 mm, and the diameter of the root portion is about 1.4 mm. Further, the length of the ball support portion 31B protruding from the pedestal portion 4 is 7.0 to 10.0 mm.
The shape and dimensions of the column base 32B are the same as the column base 32A of the outer column 3A.
The inner strut 3B is made of a flexible material like the outer strut 3A, and the diameter of the tip and the base is the same as that of the outer strut 3A. However, since the length is shorter than the outer support 3A by about 1.5 to 4.0 mm, the ratio of the thickness to the length of the inner support 3B is larger than that of the outer support 3A. Therefore, it can withstand the pressure generated when the ball is placed and pushed into the ground, despite its thin and beautifully designed appearance. In a golf tee of a type that supports a ball on a conventional support, the support supports the ball at the time of a shot and also supports the ball when the golf tee is inserted into the ground. For this reason, a certain degree of strength has to be ensured, and there is a limit to reducing the resistance during shots. However, in the present invention, since the outer support 3A and the inner support 3B are separate bodies, they can be shaped and dimensioned according to the application. Therefore, the resistance at the time of a shot can be reduced as much as possible, and at the same time, the golf tee 1 can be easily inserted into the ground with a golf ball placed thereon.
Moreover, the inner support | pillar of (2) of FIG. 4 inclines toward the outer side. This is because the golfer can see the ball easily and stably.

As described above, the golf tee 1 of the present embodiment has the support pillars arranged twice. The thin and long outer support 3 </ b> A located on the outer ring supports the golf ball at the tip and does not give a sense of resistance when shot. On the other hand, the inner strut 3B located on the inner ring withstands a considerable pressure because the shape and size are selected with priority given to the strength despite the thin appearance. As described above, the golf tee 1 on which two kinds of thin and long support columns are mounted has an appearance in which a long and narrow turf is aligned on the pedestal portion 4 and the ball is stably installed.
The golf tee of Patent Document 3 is also provided with double struts on the outside and inside, but the inside strut is intended to support the golf ball in a stable state when teeing up both the outside struts. Thus, the object of the present invention is completely different.

As shown in FIGS. 3, 6, and 7, the pedestal portion 4 has a flat cylindrical shape, and the ball support portions 31 </ b> A and 31 </ b> B of the plurality of outer struts 3 </ b> A and inner struts 3 </ b> B are respectively connected from the lower bottom surface 43 to the upper bottom surface 44. Support post through holes 41A and 41B inserted into the base and base support portions 42A and 42B for storing the support base portions 32A and 32B are provided. A fitting hole 45 for allowing the protruding portion 222 to enter is provided in the center portion of the pedestal portion 4.
Since the pedestal portion 4 is fitted to the hard tee body 2, a flexible material such as resin is appropriate.
The material of the tee body 2 may be wood or synthetic resin, but the synthetic resin has the following merits. That is, since the pedestal 4, the outer support 3A, and the inner support 3B can all be manufactured by the same supplier, the manufacturing cost can be reduced.

Each column 3 is arranged on the pedestal portion 4 as shown in FIG. The outer support column 3A and the inner support column 3B are respectively arranged on two concentric circles C1 and C2 whose center is the center O of the upper bottom surface 44 of the pedestal part 4. Eight outer struts 3A are arranged at equal intervals on the outer circumference C1, and eight inner struts 3B are arranged at equal intervals on the inner circumference C2.
Here, the reason why all the support columns 3 are arranged at equal intervals on the circumference is to support the golf ball firmly and stably.
Further, it is desirable that all of these 16 support columns are arranged in different directions with respect to the center O. This is because the number of struts lined up in the batting direction can be reduced during the tee shot.

Next, how to assemble the golf tee 1 will be described.
First, the column 3 is attached to the pedestal 4.
As shown in FIG. 6, the outer support column 3 </ b> A passes through the support column through hole 41 </ b> A from the lower bottom surface 43 to the upper bottom surface 44. A base accommodating portion 42A corresponding to the shape of the column base 32A is formed in the opening on the lower bottom 43 side of the column through hole 41A, and the outer column 3A is inserted until the column base 32A is fitted in the base accommodating portion 42A. Is done. The outer support column 3A protruding upward from the upper bottom surface 44 extends obliquely upward toward the outside at a predetermined angle formed.
As shown in FIG. 7, the inner column 3 </ b> B passes through the column through hole 41 </ b> B from the lower bottom surface 43 to the upper bottom surface 44. A base accommodating portion 42B corresponding to the shape of the column base 32B is formed in the opening on the lower bottom surface 43 side of the column through hole 41B, and the inner column 3B is inserted until the column base 32B is accommodated in the base accommodating portion 42B. Is done. The inner support column 3B protruding upward from the upper bottom surface 44 extends obliquely upward toward the outside at a predetermined angle formed.
Thus, any of the columns 3A. 3B is also inclined outward with respect to the central axis of the golf tee 1. Here, the inclination angles of the columns arranged on the same circumference are made equal. This is because an equal force is applied to the golf ball supported by the support columns 3A and 3B.

The pedestal portion 4 on which the column 3 is mounted is fitted to the pedestal receiving portion 22 of the tee body 2.
When the protruding portion 222 of the pedestal receiving portion 22 is pushed out from the fitting hole 45 at the center of the pedestal portion 4 and the fitting portion 223 connected to the protruding portion 222 is fitted into the fitting hole 45, the lower bottom surface 43 of the pedestal portion 4 becomes the tee body. The pedestal portion 4 that is in contact with the pedestal placement surface 221 of 2 and to which the support column 3 is attached is coupled to the tee body 2.
At this time, the support bases 32 </ b> A and 32 </ b> B are securely fixed by being sandwiched between the base mounting surface 221 and the base housing parts 42 </ b> A and 42 </ b> B provided on the lower bottom surface 43 of the base 4. That is, all the columns 3 are firmly fixed to the tee body 2 via the pedestal portion 4. Therefore, even if a large impact is applied during the swing, it will not fall off.

  The use of the golf tee 1 will be described separately for the operation in which the player pushes the golf tee into the ground and the operation to tee up the golf ball.

First, the usage when piercing the golf tee 1 into the ground will be described with reference to FIG. The golf ball B is pressed against the upper end portion of the inner support 3B, and the golf ball B is wrapped with the palm of the hand, and a finger is applied to the outer side surface of the tee body 2 to apply a downward force P to the golf ball B. In this way, the golf tee 1 is easily pushed into the ground G via the golf ball B.
In order to pierce the ground G, a downward force P is exerted through the golf ball B, but the base portion of the inner column 3B is thicker than the tip, and the ratio of the thickness to the length is larger than that of the outer column 3A. Therefore, excessive bending can be prevented even if a downward force is applied.
As shown in FIG. 8, the downward force P is applied to the front end portion (the portion surrounded by a broken-line circle) of each inner support 3 </ b> B via the golf ball B, and is in contact with the outer support 3 </ b> A. The force P is hardly applied. For this reason, the outer strut 3A does not need to be strong enough to withstand a considerable force P. As a result, the resistance during shots can be kept low.

Next, the usage at the time of tee-up will be described with reference to FIG.
When the leg 21 is pushed into the ground to a desired depth, the golf ball B is placed on the upper end of the outer support 3A as it is. Here, since the inner strut 3B is shorter than the outer strut 3A by 1.5 to 4.0 mm, the golf ball B is in a state of floating from the eight inner struts 3B. That is, the golf ball is supported only by the tip portion (the portion surrounded by the broken-line circle in the figure) of each outer support 3A.
When the tee shot is performed in this state, the outer support 3A is thin and flexible, so that the resistance that the golf ball B and the golf club (not shown) receive at the time of hitting is extremely small. In addition, if the club hits, the inner strut 3B, which should receive resistance, is not even in contact, so that the resistance when the golf club passes at the time of the swing is small. In addition, since the area of the tip portion of each outer support 3A is very small, the contact resistance between each outer support 3A and the golf ball B is extremely small, and the flight distance of the golf ball B can be reduced.

[Second Embodiment]
This embodiment is different from the first embodiment in that each of the outer strut and the inner strut is integrally formed. Hereinafter, this difference will be mainly described.

The outer support 5A will be described with reference to FIG.
The outer support 5A is integrally formed with a belt-like support base 52A and a plurality of ball support parts 51A provided at the upper end of the support base 52A.
As shown in the side view shown in (2) of FIG. 10, the ball support portion 51A is tapered toward the tip. Further, as shown in FIG. 10 (3), when the support base 52A is formed into a cylindrical shape, the ball support 51A is inclined outward.
It is difficult to integrally form a long and thin three-dimensional support due to mold limitations. However, as long as the outer support 5A is expanded (substantially planar), a thin and long support can be realized by integral molding.
Here, when the pedestal portion 6 is mounted, both end portions 52Aa and 52Ab of the column base 52A are held by the pedestal portion 6. However, if there is a concern about the strength, it may be stopped with a snap or an adhesive.

As shown in FIGS. 11 and 12, the pedestal portion 6 of this embodiment includes a column through hole 61 </ b> A and a base accommodating portion 62 </ b> A. The outer strut 5A is inserted until the strut base 52A is accommodated in a ring-shaped base accommodating portion 62A provided in the opening of the strut through hole 61A on the lower bottom surface 63 side. Each ball support portion 51A protruding upward from the upper bottom surface 64 extends obliquely upward toward the outside at a predetermined angle formed.

The inner strut 5B is also integrally formed in the same manner as the outer strut 5A and is attached to the pedestal portion 6. However, it goes without saying that the length of the ball support 51B is 1.5 to 4.0 mm shorter than the ball support 51A of the outer support 5A. The column base 52B of the inner column 5B is formed into a cylindrical shape, the ball support 51B is inserted into the column through hole 61B, and the ring-shaped column base 52B is accommodated in the base accommodating portion 62B of the base portion 6. Note that the ball support 51A of the outer support 5A and the ball support 51B of the inner support 5B are not arranged on the same straight line (see FIG. 11).

Since this embodiment is different only in the molding and mounting methods of the outer support 5A and the inner support 5B, the appearance is the same as shown in FIGS. 1, 8, and 9 of the first embodiment.

The above embodiments are merely examples.
The shape of the inner strut can be considered other than the first and second embodiments.
The present invention provides a golf tee having two types: a strut (inner strut) for placing a ball on a tee, placing it on a tee pedestal and inserting it into the ground, and a strut (outer strut) for placing a ball on a shot. The purpose is to provide an inexpensive and good design. The outer strut is required to be long and flexible like turfgrass, but the inner strut is only used to insert the tee into the ground. Therefore, the inner strut can be made of any material and shape as long as it is simple and inexpensive to manufacture and has a good design.
From such a viewpoint, three modifications of the inner support will be described.

First, the first modified example uses a hard material having strength. Since the inner support is separate from the outer support, a material different from that of the outer support can be used. The inner column 7 shown in FIG. 13 is integrally formed from a thin and substantially upright ball support 71 and a large-diameter column base 72.

Next, a 2nd modification reduces the number by making the shape of each inner support | pillar into a substantially plate shape. As shown in (1) of FIG. 14, the inner support column 8 is formed by integrally forming a ball support portion 81 and a support column base portion 82 having a circular cross section. FIG. 14 (2) shows a state in which the four inner struts 8 are mounted on the pedestal, but the number may be determined based on the shape and material of one inner strut 8.

Next, as shown in FIG. 15 (1), the inner support column 9 of the third modified example is integrally formed with a cylindrical ball support portion 91 and a support base portion 92 provided continuously with the lower end portion. The ball support 91 may be provided with an arbitrary number of cuts 93 and divided into ball support pieces 94 corresponding to the number of cuts 93. In the example of FIG. 15, the ball support piece 94 is divided into two ball support pieces 94 by two cuts. The number of cuts and the width of one cut 93 may be determined in consideration of the strength of the material.

  The shape of the tee body of the above embodiment is merely an example. The pedestal receiving portion 22 of the tee main body 2 may be any shape that can be fitted into the fitting hole 45 of the pedestal portion 4. Moreover, the leg part of the tee body 2 is not limited to the one that becomes thinner toward the tip as shown in FIG. 1, and the middle part may be thickened. If it is this, it is easy to keep the depth when inserting a tee into the ground.

In the embodiment described above, the number of the outer support pillars 3A is eight. However, the number is not limited to eight, and it is necessary to support the golf ball B in consideration of the weight of the golf ball B and the material of the outer support pillar 3A. What is necessary is just to make the minimum number.
In the first embodiment, the outer support 3A and the inner support 3B are formed one by one, and in the second embodiment, they are integrally formed. However, two pieces may be integrally formed and connected at the root portion. If it is this, manufacture of a metal mold | die is also easy and the effort at the time of attaching to a base part is also reduced.

  Each member constituting the golf tee of the present invention can be formed of a synthetic resin. Recently, since a transparent synthetic resin has been available, it may be used for the golf tee of the present invention. When a golf ball is stabbed on the grass of the golf course and placed on the grass, it is as if the ball is floating at the desired height, and both players and visitors can play sports under nature You can feel and enjoy yourself. And at the time of a shot, it is possible to hit a ball placed only on a thin and long support.

Since the golf tee of the present invention can reduce the resistance at the time of hitting as much as possible, it can provide a comfortable shot feeling like hitting a golf ball on the lawn, and has a long flight distance, and can be applied to a recent large golf head. Furthermore, since it can pierce easily to the ground, many demands can be expected.
