Description

  The present invention relates to a golf tee used at a golf course or a golf tee used at a golf driving range or at home. In particular, the present invention relates to a golf tee in which a contact portion with a ball has a brush shape constituted by a plurality of hair bundles.

  When a first hit is made on a golf course, a golf tee is often used to hold the golf ball at a height that is easy to hit. Conventional golf tees are made of wood or resin rods, and one end is thin and sharp so that it can be inserted into the ground or grass, and the other end can support the lower part of the golf ball. Slightly hemispherically to form a hemispherical ball receiving portion.

  The diameter of the ball receiving portion of the conventional golf tee is considerably smaller than the diameter of the golf ball. The ball receiving portion and the golf ball are in contact with each other in a substantially circular region, but since the ball receiving portion is small, the contact area is very small and the stability of the ball is poor. For this reason, the golf ball once placed on the golf tee often rolls off. As one improvement method for placing the golf ball stably on the golf tee, it is conceivable to enlarge the ball receiving portion. However, when the ball receiving portion of the conventional golf tee is enlarged to increase the contact area with the golf ball, the contact resistance between the golf ball and the golf tee increases. An increase in the contact resistance between the golf ball and the golf tee leads to a decrease in the flight distance of the golf ball, so it is necessary to avoid it as much as possible. For this reason, in the conventional golf tee, it is not preferable to enlarge the ball receiving portion.

  Further, the conventional golf tee applies a reaction force to the club when the player hits the golf ball and the ball receiving portion at the same time with the club. When a player hits a golf tee and feels a reaction force, the player feels the swing of the club worse, and the club head speed often decreases. As a result, the kinetic energy transmitted to the golf ball decreases, and the flight distance of the golf ball decreases.

  Furthermore, when a conventional golf tee is struck by a club, the golf tee flies off from the ground or the grass and may be lost. It has been pointed out that the lost plastic golf tees become garbage on golf courses and are damaged by the lawn mower teeth.

  Various golf tees have been disclosed in order to improve various problems of the conventional golf tee as described above. For example, Patent Document 1 discloses a golf tee that is branched into a plurality of portions such that the tip of the ball receiving portion has the same height, and supports the golf ball at the tip of the branch portion. Since the tip of the ball receiving portion is branched into a plurality, the contact area between the ball receiving portion and the golf ball is smaller than that of the conventional golf tee, and the contact resistance is reduced. The golf tee of Patent Document 1 having such a configuration is expected to increase the flight distance of the golf ball. However, the diameter of the ball receiving portion of the golf tee of Patent Document 1 is almost the same as that of the conventional golf tee, and the stability of the golf ball placed on the golf tee is not improved.

  Patent Document 2 discloses a golf tee in which a pedestal portion is provided on an upper portion of a rod-like base portion, and hair bundles extending perpendicularly to the upper surface of the pedestal portion are planted in an annular shape. In the golf tee of Patent Document 2, the tip portion of the hair bundle planted in an annular shape makes a point contact to hold the golf ball, and the contact area with the golf ball is smaller than that of the conventional golf tee. Has been reduced. Each hair constituting the hair bundle is made of resin and is sufficiently thin, and is easily bent when the head of the golf club comes into contact during a swing. Therefore, even when the player strikes the hair bundle during the swing, the reaction force felt by the player is smaller than before, and an effect of improving the swing-out feeling and avoiding a decrease in the flight distance can be obtained. Further, the golf tee of Patent Document 2 has a low possibility that the entire golf tee will fly off the ground or the turf even if the hair bundle portion is hit, and the golf tee can be prevented from being lost. Golf tees having a configuration similar to that of Patent Document 2 are disclosed in Patent Documents 3 and 4.

  In the golf tees of Patent Documents 2, 3, and 4, hair bundles having a uniform length are implanted vertically in the pedestal portion. When a golf ball, which is a sphere, is placed on the tip of this hair bundle, some hairs constituting the hair bundle favorably support the golf ball at the tip, but the hair is planted at a position closer to the center of the pedestal. Some of the bristles are pressed down on the surface of the golf ball so that the golf ball reaches a lower position and support the golf ball in an irregularly elastic state. On the other hand, some hairs planted near the outer periphery of the pedestal do not reach the surface of the golf ball and do not support the golf ball at all. For this reason, when the golf ball is placed on the golf tees of Patent Documents 2, 3 and 4, only a part of the hair of the hair bundle is supported on the golf ball, and the golf ball is pressed down on the lower side of the golf ball. Then, the elastically deformed hair tries to return to its original state, and a force is applied in the direction of pushing up the ball.

  As a result, the golf tees of Patent Documents 2, 3 and 4 have poor stability of golf balls placed on the same level or more as conventional golf tees. For example, when a player drops a golf ball on the golf tee, if the golf ball slightly deviates from the center of the golf tee, the golf ball rolls down. Even when the golf tee is slightly tilted or a weak wind blows, the golf ball rolls off the golf tee.

  When a golf ball is placed on the golf tees of Patent Documents 2, 3 and 4, there is also a problem that the hair elastically deformed irregularly under the golf ball pushes the golf ball and moves the golf ball on the golf tee. To do. The change of the position of the golf ball on the golf tee is a very inconvenient phenomenon especially for a player who wants to confirm the direction of the hit ball by a mark drawn on the surface of the golf ball. In addition, when a golf tee is held by hand with the golf ball placed on it and stabbed into the ground or turf, it is difficult to hold the golf ball due to the reaction force from the hair bundle, which is inconvenient.

  Patent Document 5 discloses a golf tee in which a pedestal portion is provided on an upper portion of a rod-like base portion, and a hair bundle extending toward the upper side of the pedestal portion is planted on the upper surface of the pedestal portion. The tip of the hair bundle is processed so as to form a spherical surface that substantially coincides with the surface of the golf ball, and the golf ball can be stably supported. However, in the golf tee of Patent Document 5, since the contact area between the golf ball and the tip of the golf tee is wide, the resistance is large, and the flight distance of the hit ball may be lower than the conventional golf tee. Moreover, since it is difficult to process the front-end | tip part of a hair | bristle bundle in the shape substantially corresponded to the surface of a golf ball, production efficiency is bad and manufacturing cost starts.

  Patent Document 6 discloses a golf tee in which a pedestal portion is provided on an upper portion of a rod-like base portion, and a plurality of hair bundles extending obliquely upward of the pedestal are planted on the upper surface of the pedestal portion. In such a golf tee, it is necessary to optimize the angle at which the hair bundle is implanted on the pedestal. If the inclination angle of the hair bundle is too small, the angle of the hair bundle with respect to the golf ball is almost a right angle, and the number of hairs suitably contacting the spherical ball is reduced. The golf tee of Patent Document 6 having such a configuration cannot obtain the effect of stably supporting the golf ball, similarly to the golf tees of Patent Documents 2, 3, and 4. On the other hand, if the inclination angle of the hair bundle is too large, the hair bundle cannot be supported by the load applied in the vertical direction from the golf ball, so the hair bundle falls and the golf ball sinks into the hair bundle, and the player Cannot hold the ball in the intended position. When the golf ball sinks into the hair bundle, the contact area between the hair bundle and the golf ball increases, and the contact resistance between the golf ball and the golf tee increases. There is a fear that the flight distance of the golf ball may drop more than when it is used.

  As described above, in the golf tee of Patent Document 6, unless the angle at which the hair bundles are implanted is optimized, stable support of the golf ball placed on the tee and reduction of contact resistance with the golf ball can be achieved. Although the two problems of securing the distance cannot be solved, such examination contents are not disclosed. In addition, the golf tee described in Document 6 has a problem that it is very difficult to plant the hair bundle, and it takes time to adjust the length of the tip of the hair bundle.

  Patent Document 7 discloses a golf tee in which a pedestal portion is provided on an upper portion of a rod-like base portion, and a long hair bundle extending perpendicularly to the pedestal and a short hair bundle are planted on the upper surface of the pedestal portion. However, Patent Document 7 does not specifically disclose the heights of long and short hair bundles of long and short hair bundles. For this reason, in the golf tee of Patent Document 7, both the long hair bundle and the short hair bundle cannot stably support the golf ball, and the tip of the long hair bundle without contact between the short hair bundle and the golf ball. There is a possibility that the golf ball is supported only by the portion, or that the long hair bundle is elastically deformed and bent irregularly. Further, in the arrangement of short hair bundles disclosed in Patent Document 7, the contact area (region) with the golf ball is very narrow. As a result, it is clear that the golf tee of Patent Document 7 is a golf tee that cannot hold a golf ball stably, as in Patent Document 2, Patent Document 3, and Patent Document 4.

  Patent Document 8 discloses a golf tee in which short string-like materials are arranged in a ball receiving portion. The string-like materials are arranged in a funnel shape one by one on the outer peripheral portion and one by one in the center portion. The string-like material arranged upright functions merely as an impact absorbing portion at the time of hitting, and the golf ball is supported only by the string-like material arranged in a funnel shape on the outer peripheral portion.

  Since the golf tee of Patent Document 8 has a small number of string-like materials that substantially support the golf ball, each string-like material needs to be configured with sufficient strength. Therefore, even if this chordal material is flexible, the player feels the reaction force from the chordal material when the golf ball and the chordal material are hit at the same time in the club. End up. As described above, in the golf tee of Patent Document 8, the feeling of swinging out of the club is not sufficiently improved. Further, in the golf tee of Patent Document 8, as in the golf tees of Patent Documents 2, 3, 4, 6, and 7, optimization of the number, length, arrangement, or inclination angle of the members that support the golf ball is completely performed. Since it is not broken, the golf ball cannot be stably supported.

Conventionally, as shown in Patent Document 9, a cylindrical golf tee made of a flexible material such as rubber has been used in a driving range or at home.

  Conventional golf tees stably support the golf ball, reduce the contact resistance with the golf ball, and improve the feeling of swinging the golf club without feeling reaction force during the swing. It was impossible to achieve all of these simultaneously. The golf tee of the present invention overcomes the conventional problems, stably supports the golf ball, reduces the resistance to the golf ball, improves the feeling of swinging the golf club, and the golf ball flight distance It was created as an issue to provide a golf tee that can stretch the length.

  The invention of claim 1 is a rod-like base portion that can be inserted into the ground or turf, a pedestal portion that is provided perpendicularly to the base at the upper end of the base portion, and a plurality of hairs fixed to the upper surface of the pedestal portion The present invention relates to a golf tee composed of a flocked portion composed of a bundle. The flocking portion of the golf tee of the present invention is configured by regularly arranging a short hair bundle extending in the vertical direction with respect to the pedestal portion and a long hair bundle extending upward while inclining outward, At the same time as supporting the lower part of the golf ball on which the tip of the short hair bundle is mounted, the tip of the golf ball on which the tip of the long hair bundle is mounted is positioned higher than the reaching position of the tip of the short hair bundle. It is characterized by supporting.

  In the golf tee of the first aspect, the front end portion of the short hair bundle planted vertically supports the lower portion of the golf ball on which it is placed with almost no deformation. On the other hand, the slanted long hair bundle is regularly elastically deformed so as to be further opened in the direction tilted from the beginning by contacting with the golf ball. The tip of the deformed long hair bundle reaches the certain position higher than the tip of the short hair bundle and gives the golf ball a force to return to the position before the deformation. As a result, the golf tee of the present invention supports the golf ball at two different heights by the short hair bundle and the long hair bundle. And the long hair | bristle bundle has applied the equal force which clamps the outer periphery of a golf ball to the outer peripheral part of a golf ball in the direction which goes to the center part of a golf tee. For this reason, the golf ball is stably and efficiently supported by a small hair bundle.

  The long hair bundle exerts a uniform force on the outer periphery of the golf ball, so that the position of the golf ball once placed on the golf tee hardly moves. In addition, when the golf ball is placed at a position off the center of the flocked portion of the golf tee, a part of the long hair bundle is greatly deformed, and as a result, only a part of the long hair bundle is a long hair bundle of the other part. A greater force is applied to the golf ball. The golf ball moves to a position where the center of the flocked portion and the center of the golf ball substantially coincide with each other due to the force from a part of the long hair bundle. After this movement, the golf ball receives an equal force from the long hair bundle on the outer periphery. Stabilize. Thus, the golf tee of the present invention not only stably supports the golf ball, but also corrects the position when the golf ball is placed at an unstable position off the center on the golf tee. Has a function.

  In addition, the golf tee of the present invention supports the golf ball at the tip of the hair bundle, and the contact area between the golf ball and the tip of the hair bundle is small. For this reason, the contact resistance between the golf tee of the present invention and the golf ball is greatly reduced. Further, since the long hair bundle and the short hair bundle are easily bent when the golf club head comes into contact with the swing, the player hardly feels the reaction force even when the player strikes the hair bundle. As a result, the golf tee of the present invention can stably support the golf ball, and at the same time realize a reduction in contact resistance and a good feeling of swinging out of the club, as compared with a conventional wooden or resin rod-shaped golf tee. It is possible to increase the flight distance of the golf ball. In addition, the golf tee of the present invention can prevent the golf tee from being lost without hitting the hair bundle portion so that the entire golf tee does not fly off the ground or the turf.

  In the golf tee of the present invention, a rod-like base is inserted into the ground or turf and fixed. When a golf ball and golf tee are held by hand and are stabbed into the ground or turf, the long hair bundle of the golf tee against which the golf ball is pressed is regularly elastically deformed so as to open further in the outward direction which was inclined from the beginning. No irregular reaction force is generated. Therefore, the player can shoot the golf ball and golf tee together on the ground or turf without feeling uncomfortable.

  The long hair bundle constituting the flocked portion of the golf tee according to claim 2 is inclined at an angle of 2.0 degrees or more and 7.0 degrees or less obliquely outward with respect to the vertical direction of the pedestal section. And

  As a result of intensive studies, the inventor of the present invention has come to specify a preferable angle of the long hair bundle constituting the hair transplantation part of the golf tee. The preferred angle of the long hair bundle here means that when the golf ball is placed, it is elastically deformed regularly toward the outside of the pedestal, and its tip reaches a certain height on the outer periphery of the golf ball, An angle that can be supported by applying a uniform force toward the inside of the golf ball.

  As a result of various studies, when the inclination angle of the long hair bundle is smaller than 2.0 degrees, the long hair bundle bends irregularly when the ball is placed and contacts the golf ball. It has been found that the hair enters the bottom surface of the golf ball and exerts a non-uniform force that lifts the golf ball upward. Further, when the inclination angle of the long hair bundle is larger than 7.0 degrees, the amount of hair bundle collapse increases, so that most of the hair of the long hair bundle does not contact the golf ball, and the golf ball is short. It will sink into the hair bundle. For this reason, a short hair bundle is pressed on the surface of the golf ball and irregularly elastically deformed so that it contacts the golf ball, and exerts an uneven force to lift the golf ball upward, and at the same time, the hair bundle and the golf ball As a result, the contact resistance of the golf club increased and the swinging feeling of the golf club deteriorated.

  Thus, in the golf tee of the present invention, it is preferable that the long hair bundle is inclined outwardly at an angle of 2.0 degrees or more and 7.0 degrees or less with respect to the vertical direction of the pedestal portion, exceeding the range. It has been clarified that the long hair bundle planted in this manner cannot provide the effect of stably supporting the golf ball and supporting the golf ball and the golf club in a low resistance state.

  In the golf tee of claim 3, the height of the distal end portion of the long hair bundle fixed to the pedestal portion is 1.0 mm or more and 4.0 mm or less than the height of the distal end portion of the short hair bundle fixed to the pedestal portion. It is characterized by an increase.

  As a result of various studies, the inventor has found that the contact resistance value with the golf ball is low and the height difference between the short and long hair bundles that can stably support the golf ball with a small hair bundle. Succeeded in identifying. That is, a golf tee in which the height difference between the tip of the short hair bundle and the tip of the long hair bundle is smaller than 1.0 mm is the same as the golf ball height supported by the short hair bundle and the ball supported by the long hair bundle. The difference in height is not enough, and the deformation of the long hair bundle is small, so the golf ball is supported only in the vertical direction at almost the same height, and the golf ball has insufficient stability. There was found. On the other hand, golf tees in which the difference in height between the tip of the short hair bundle and the tip of the long hair bundle is larger than 4.0 mm often cause the lower surface of the golf ball to not reach the tip of the short hair bundle, Since the golf ball is supported only by the bundle, it has been found that the stability of the golf ball is insufficient even in this case. Thus, the height of the tip of the long hair bundle fixed to the pedestal portion is 1.0 mm or more and 4.0 mm or less higher than the height of the tip of the short hair bundle fixed to the pedestal portion. It is preferable that the golf ball cannot be stably supported by the golf tee in which the difference in the length of the hair bundle exceeds the range.

  In the golf tee of claim 4, at least eight flock holes are annularly arranged on the upper surface of the pedestal portion, and at least four long bristles and at least four short bristles are alternately arranged one by one in the flock holes. The hair transplantation part is formed by being fixed to. Accordingly, the short hair bundle regularly supports the golf ball, and at the same time, the long hair bundle can regularly support the golf ball at a position higher than the short hair bundle.

  Here, the number of flock holes can be 8 or more, but even in that case, the number of flock holes is preferably an even number. By alternately planting short hair bundles and long hair bundles in all even number of flock holes, short hair bundles and long hair bundles are always arranged alternately. The bundles are not planted next to each other. As a result, the distance between the short and short hair bundles can be made uniform, and at the same time, the distance between the long and long hair bundles can be made uniform, and the golf ball can be efficiently stabilized with a small number of hair bundles. Thus, it is possible to support with equal force.

  The golf tee of claim 5 includes at least eight flocked holes on the upper surface of the pedestal portion, and the flocked holes are annularly arranged in a region having a radius of 6.0 mm to 11.0 mm from the center of the upper surface of the pedestal portion. The long hair bundle and the short hair bundle are alternately fixed to the flock hole one by one to form a hair transplant portion. By fixing the long hair bundle and the short hair bundle alternately to the follicle hole one by one, the tip of the hair bundle is above the pedestal portion and has a radius of about 6.0 mm or more from the center of the upper surface of the pedestal portion. It is arranged in a ring shape in a region of 0.0 mm or less.

  As a result of the study, when the flocked hole is arranged in the region inside the radius 6.0 mm from the center of the upper surface of the pedestal portion, the long hair bundle and the tip of the short hair bundle to be implanted there are mostly the pedestal. It has been found that the region extends from the center of the upper surface of the portion within a radius of 9.0 mm. The tip of the hair bundle in this region supports the central portion of the lower surface of the placed golf ball, and it became clear that the golf ball cannot be stably supported only by the hair bundle in this region. In order to support the position on the outer side of the lower surface of the golf ball, a configuration in which the long hair bundle is further inclined to the outside is conceivable. However, as described above, the angle at which the long hair bundle is inclined to the outside is 2.0. From 7.0 degrees to 7.0 degrees is preferable, and long hair bundles planted at an angle larger than this cannot contribute to stably supporting the golf ball. For this reason, it has become clear that the position of the flocked hole is preferably arranged in a region outside the radius of 6.0 mm regardless of the angle of the long hair bundle to be flocked there.

  On the other hand, when the flocking hole is arranged in a region outside the radius of 11.0 mm from the center of the upper surface of the pedestal portion, most of the tip of the long hair bundle to be implanted here is outside the radius of 11.0 mm. Clearly located in the region. As a result of the study, the long hair bundle positioned in the region outside the radius of 11.0 mm cannot support the golf ball because a part of the tip portion does not contact the golf ball. And it was confirmed that the force which supports a golf ball becomes weak in the golf tee arrange | positioned in the area | region outside a radius of 11.0 mm from the center of the upper surface of a base part. From the above examination results, it is possible to support the golf ball efficiently and stably with a small hair bundle by arranging the flock holes in a ring shape in a region having a radius of 6.0 mm or more and 11.0 mm or less from the center of the upper surface of the pedestal. It turned out to be possible.

  In the golf tee of claim 6, at least eight flock holes are arranged in an annular shape on the upper surface of the pedestal portion, and either one of the flock holes in which long bristles are flocked or the flock holes in which short follicles are flocked. The marking corresponding to is performed.

  A flocking hole and a short hair bundle for reliably planting a long hair bundle by marking corresponding to either a flock hole for planting a long hair bundle or a flocking hole for planting a short hair bundle. It is possible to perform flocking by discriminating flock holes for flocking. According to the present invention, it is possible to efficiently and quickly produce a golf tee in which long hair bundles and short hair bundles are planted reliably. In addition, as marking, it is possible to apply the method of forming a linear convex part around the flocking hole of any one of a base part, the mark by a coating material, etc.

  In the golf tee of claim 7, the diameter of the hair constituting the long and short hair bundles of the flocked portion of the golf tee is 0.3 mm or more and 0.7 mm or less, preferably the hair diameter is 0.4 mm or more. It is 0.6 mm or less.

  When hair having a diameter smaller than 0.3 mm is applied to a short hair bundle, rigidity as the hair bundle is insufficient and it is difficult to support the golf ball at a certain height. In specifying the thickness of the hair bundle of the present invention, we also studied changing the material of the hair bundle to a highly rigid material, but the hair having a diameter of less than 0.3 mm and capable of stably supporting a golf ball is When it is applied to a long hair bundle, it hardly deforms to fall outward, and the golf ball is supported only by the long hair bundle, so that it cannot be applied to the golf tee of the present invention. On the other hand, when a hair having a diameter larger than 0.7 mm is applied to the hair bundle, the contact area with the golf ball is increased regardless of the material of the hair to be applied and the number of the hair bundle, and the contact resistance is increased. It has been found that the flying distance is lower than that of a conventional golf tee and the feeling of swinging out of the club is poor. The golf tee of the present invention is a golf ball that is stable and has a low contact resistance by setting the diameter of the hair constituting the long hair bundle and the short hair bundle of the flocked portion to 0.3 mm or more and 0.7 mm or less. Can be supported.

  As a result of further investigation, the golf tee of the present invention has a hair diameter to be applied by setting the diameter of the hair constituting the long hair bundle and the short hair bundle of the flocked portion to 0.4 mm or more and 0.6 mm or less. It was revealed that the golf ball can be stably supported regardless of the rigidity, the number of hair bundles, and the length of the hair.

  The golf tee of claim 8 has a hair diameter of 0.6 mm to 0.7 mm among the hair bundles constituting the flocked portion of the golf tee, and the hair constituting the long hair bundle. The diameter is 0.3 mm or more and 0.4 mm or less.

  By applying thick hair to the hair of the short hair bundle, the rigidity of the short hair bundle is increased and the force for supporting the golf ball vertically is increased. As a result, it is possible to prevent the golf ball from sinking into the hair bundle and increasing the contact resistance between the golf ball and the hair bundle. In addition, by applying hair that is thinner than short hair to long hair, it is easier for the long hair to be deformed more regularly toward the outer periphery, and to support the periphery of the golf ball more uniformly. It becomes possible.

  In the golf tee of claim 9, the number of hairs constituting the short hair bundle and the long hair bundle of the flocked portion is 10 or more and 20 or less per bundle, preferably 12 or more and 16 or less per bundle. It is characterized by being. When the number of hairs per bundle is 9 or less, the support for the golf ball as the whole hair bundle becomes too weak because there are few fulcrums. On the other hand, when the number of hairs per bundle is 21 or more, the contact area between the hair bundle and the golf ball increases, and the value of contact resistance increases. The golf tee of the present invention increases the resistance value of the golf tee and the golf ball by setting the number of hairs constituting the short bundle of hairs and the long bundle of hair to 10 to 20 per bundle. In addition, the golf ball can be stably supported. As a result of further investigation, the number of the hairs constituting the short hair bundle and the long hair bundle in the flocked portion is set to 12 or more and 16 or less per bundle, so that the hair material, strength, and hair length to be applied It has become clear that the golf ball can be supported stably regardless.

  In the golf tee of claim 10, at least eight flock holes are annularly arranged on the upper surface of the pedestal portion, and the side wall of the flock hole to which the long hair bundle is fixed is obliquely outwardly 2.0 degrees or more and 7.0 degrees. By inclining at the following angle and fixing the long hair bundle along the side wall of the flocked portion, the long hair bundle is at an angle of 2.0 degrees or more and 7.0 degrees or less obliquely outward with respect to the central axis of the base portion. Inclined at an angle.

  In the golf tee of claim 11, it is preferable that at least eight flocking holes are annularly arranged on the upper surface of the pedestal portion, and a concave portion or a circular groove is provided inside the flocking hole on the upper surface of the pedestal portion. .

  By providing a concave or circular groove on the upper surface of the pedestal, it is possible to reduce sink marks (deformation due to shrinkage during molding) when the pedestal is processed, and to accurately form the dimensions of each part of the pedestal It becomes. In particular, the shape of the flock hole arranged near the recess can be formed with high accuracy, and the angle of the hair bundle is arranged with high accuracy.

  The invention according to claim 12 is fixed to the upper surface of the base part, a rod-like base part that can be inserted into the ground or turf, a truncated cone-shaped base part provided perpendicularly to the base part at the upper end of the base part The present invention relates to a golf tee composed of a flocked portion composed of a plurality of hair bundles. In the golf tee of the present invention, the flocked portion is composed of a long hair bundle and a short hair bundle arranged on two or more concentric circles virtually imagined on the upper surface of the pedestal portion. The long hair bundles are arranged on the outermost circle that is virtually outside and are arranged at positions where the distances between the long hair bundles are equal, and are fixed so as to extend upward while being inclined outward. The short hair bundles are on one or more circles imaginary on the inner side, and are arranged at positions where the intervals between the short hair bundles arranged on the same circle are equal, and on the upper surface of the pedestal portion. It is fixed so as to extend in the vertical direction. The tip of the short hair bundle arranged on the inside supports the lower part of the mounted golf ball, and the tip of the long hair bundle arranged on the outermost side is the lower part of the mounted golf ball and has short hair. It is characterized by supporting a position higher than the arrival position of the tip of the bundle.

  The golf tee of the present invention supports the golf ball vertically at a position where the short hair bundle is closer to the center of the golf ball. Since the difference in height of the ball is small at a position closer to the center of the bottom of the golf ball, most of the hair of the short hair bundle does not cause elastic deformation and efficiently contacts the bottom of the golf ball to support the golf ball. To do. On the other hand, the long and slanted hair bundle disposed on the outermost side is regularly elastically deformed so as to open further in the direction inclined from the beginning by contacting with the golf ball. The deformed long hair bundle has a tip portion that reaches a position at a certain height of the golf ball, and applies a force to the golf ball to return to the position before the deformation. The golf tee of the present invention can support different positions of the golf ball at different distances because the flocking position in the radial direction at the center of the base portion of the short hair bundle and the long hair bundle is different. The ball can be supported stably.

First Example FIG. 1 schematically shows a side view of a golf tee 2 of this example. The golf tee 2 according to this embodiment includes a base portion 4, a pedestal portion 6, and a flocked portion 8.

  The base 4 is a rod-like member provided at the lower part of the golf tee 2. The base 4 is formed so as to gradually become thinner toward the lower end so that it can be inserted into the ground or the lawn. The base 4 is formed of an arbitrary material such as resin or wood having a strength that can be inserted into the ground.

  A cross-sectional view of the base 4 and the pedestal 6 is shown in FIG. The pedestal 6 has a frustoconical appearance. That is, the outer periphery of the upper surface and the outer periphery of the lower surface of the base part 6 are formed in a circular shape, and the positions of the centers of these circles coincide. The side surface portion of the pedestal portion is formed smoothly so as to connect the upper surface and the lower surface. In this embodiment, the upper surface of the pedestal 6 is a substantially flat circle with a radius of 11.5 mm, and the lower surface is a circle with a radius of 12.5 mm. A plurality of flock holes 14 are arranged on the upper surface of the base portion 6. The upper end of the base portion 4 is connected to the center of the lower surface of the pedestal portion with a smooth curve having a radius of 0.5 mm or more. The base 4 is connected perpendicularly to the pedestal 6, and the central axis of the base 4 coincides with the central axis of the golf tee 2. The pedestal portion 6 can be integrally formed of the same material as the base portion 4. It is also possible to use a material that can easily form the flocked portion 8 for the pedestal portion 6 and use a hard material for the base portion 4 to separately form the base portion 4 and the pedestal portion 6 and then join them together. In this embodiment, the base 4 and the pedestal 6 are integrally formed of the same material resin.

  In order to mold the base 4 and the pedestal 6 with a resin, the mold 4 can be molded integrally with the base 4 and the pedestal 6, and the mold dividing line (party) on the side of the pedestal 6 where the resin inlet is molded. It is preferable to use a mold provided at a position corresponding to the (grind line). By providing the resin inlet at this position of the mold, a very favorable effect is brought about when the base portion 6 having the flock holes 14 on the upper surface is molded. That is, since the injection port is provided at a position near the flock hole 14 on the upper surface of the pedestal 6, the resin is injected around the flock hole 14 with sufficient pressure applied, so the pedestal is molded. Occurrence of sink marks (shrinkage deformation at the time of processing) during processing is reduced.

  A circular recess 7 having a radius of approximately 1.5 to 5.0 mm is formed in the center of the pedestal 6. By forming such a recess 7, sink marks when forming the pedestal portion 6 are further suppressed. As a result, the shape and the inclination angle of the flock holes arranged on the outside of the concave portion 7 are formed with high accuracy. In addition, the same effect can be acquired also by shape | molding the circular groove | channel 9 on an upper surface instead of the recessed part 7 as shown in FIG.2 (b).

  A top view of the pedestal 6 is shown in FIG. On the outer side of the recess 7 on the upper surface of the pedestal portion 6, in order to alternately arrange long hair bundles and short hair bundles in an annular shape, 16 flocking holes 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h , 14i, 14j, 14k, 14l, 14m, 14n, 14o, 14p are arranged at equal intervals. The cross-sectional shapes of the flock holes 14a to 14p in this example are all circular with a radius of 1.25 mm. The distances from the center of the flock holes 14a to 14p to the center of the upper surface of the pedestal 6 are all 8.75 mm, and the recess 7 is formed on the inside. Here, the eight flock holes 14 a, 14 c, 14 e, 14 g, 14 i, 14 k, 14 m, and 14 o are inclined by 3.0 degrees in the obliquely outward direction with respect to the central axis of the golf tee 2. The distances from the center of the opening to the center of the upper surface of the pedestal 6 are all 8.75 mm. Here, FIG. 3B shows a top view of the pedestal portion 6 in which a circular groove 9 is formed instead of the recess 7.

  An elliptical marking is formed on the upper surface of the pedestal portion 6 and in a region between the flock hole and the concave portion 7 inclined obliquely outward by 3.0 degrees. In this embodiment, eight oval markings 15a, 15b, 15c, 15d, and 15e are provided so as to correspond to the eight flock holes 14a, 14c, 14e, 14g, 14i, 14k, 14m, and 14o, respectively. , 15f, 15g, 15h are molded. The shapes of the markings 15a to 15h are all the same. With the markings 15a to 15h, it is possible to easily identify a flock hole inclined obliquely outward and a vertical flock hole.

  A flocked portion 8 is formed on the upper surface of the pedestal portion 6. The flocked portion 8 is perpendicular to the upper surface of the pedestal portion 6 and has a short bunch of short bundles 10 extending parallel to the central axis of the golf tee 2 and a pedestal portion with respect to the central axis of the golf tee 2 6 is composed of eight long bundles of hair that are inclined 3 degrees in the direction toward the outer periphery, that is, obliquely outward. Short hair bundles and long hair bundles are alternately arranged one by one so that adjacent hair bundles are always different in height. In the side view of the golf tee 2 in FIG. 1, four bundles 10 a, 10 b, 10 c, and 10 d of the eight bundles of short bundles 10 are shown. Five bundles of hairs 12a, 12b, 12c, 12d, 12e are shown.

  In the present embodiment, the eight short bundles of hairs 10 are each formed by bundling 14 hairs (wires) having a diameter of 0.5 mm made of polyamide. The short hair | bristle bundle 10 is adjusted so that the height from the pedestal part lower surface when planted may be set to 45.0 mm.

  Each of the eight long bundles 12 in this embodiment is composed of 14 bundles of polypropene having a diameter of 0.5 mm. The height from the lower surface of the pedestal portion when the hair is implanted is adjusted to be 47.0 mm.

  A method for forming the hair transplant part 8 on the base part 6 will be described in more detail with reference to FIG. First, eight bundles of short hair bundles 10 are planted on the base 6, and then eight bundles of long hair bundles 12 are planted. A rod-shaped metal piece slightly longer than the diameter of the flock hole formed of a metal harder than the base portion 6 is used for flocking the hair bundle. Hereinafter, this metal piece is referred to as a flat wire.

  The method of planting the hair bundle 10a will be described as an example with respect to the eight short bundles 10 to be planted first. For the hair bundle 10a, seven polyamide hairs longer than 90.0 mm are used. The seven hairs are bundled and folded in half at the center. The flat wire is sandwiched between the folds of the seven hairs, and the hair bundle and the flat wire are pushed into the follicle hole with a strong force. The hair for the short hair bundle 10a is pushed into the flock hole 14b provided vertically. The hair fixed by being pushed into the vertical flock hole becomes a hair bundle 10a composed of 14 hairs.

  The remaining 7 bundles of short hair bundles are pushed into the vertical flock holes 14d, 14f, 14h, 14j, 14l, 14n, and 14p in the same manner, and fixed, thereby forming the 8 short bundles of hairs 10. FIG. 4A shows a side view of the golf tee 2 immediately after the eight short hair bundles 10 are fixed to the base portion 6. As shown in FIG. 4B, the fixed short hair bundle 10 is aligned by cutting the front end portion so that the height from the lower surface of the pedestal portion is 45.0 mm.

  When the planting of the short hair bundle 10 is completed, the planting of the next long hair bundle 12 is started. A method for flocking the hair bundle 12a in the eight long hair bundles 12 will be described as an example. For the long hair bundle 12a, seven polypropene hairs longer than 94.0 mm are used. The seven bristles are bundled and folded in half at the center to sandwich the flat wire. The hair for the long hair bundle 12a is pushed into the flock hole 14a identified by the marking 15a. Since the side wall of the flock hole 14a is inclined 3.0 degrees obliquely outward with respect to the central axis of the golf tee 2, the hair pushed into the flock hole is inclined with respect to the central axis of the golf tee 2. It tilts outward at an angle of 3.0 degrees and is fixed in that state.

  The remaining seven bundles of short hair bundles are pushed and fixed in order into the remaining seven flock holes 14c, 14e, 14g, 14i, 14k, 14m, and 14o inclined obliquely outward in the same manner as the hair bundle 12a, Eight long bundles of hair 12 that extend obliquely outward are formed. FIG. 4C shows a side view of the golf tee 2 immediately after the eight long hair bundles are fixed to the pedestal portion 6. As shown in FIG. 4 (d), the fixed long hair bundle is aligned by cutting the tip so as to have a length of 47.0 mm.

  Since most of the tips of the hairs constituting the long hair bundle 12 after being trimmed are inclined to the outside, the tips of the majority of the hairs constituting the short hair bundle 10 are implanted. , Reach the outside in the radial direction of the pedestal. The difference between the arrival position of the short hair bundle 10 and the arrival position of the tip of the long hair bundle 12 is 2.3 mm on average.

  FIG. 5 shows an s diagram in which the golf ball 16 is placed on the golf tee 2. The golf ball 16 used in this example has a diameter of 42.7 mm and a weight of 45.9 g. The size and weight of the golf ball 16 are most widely distributed in Japan and are almost the same as those used in official games.

  In the golf tee 2, the tips of the eight short bundles 10 support the lower part of the golf ball 16 with almost no deformation. At this time, the golf ball 16 receives a vertical force from a short hair bundle, so that the golf ball 16 can be efficiently supported by a small number of hair bundles. On the other hand, the eight long hair bundles 12 are regularly elastically deformed so as to be further opened in the outward direction inclined by 3.0 degrees by contacting the golf ball 16. The distal end portion of the long hair bundle 12 reaches a position higher than that of the short hair bundle 10 even after the elastic deformation, and acts on the golf ball 16 to return to the position before the deformation. As a result, the golf tee 2 of the present embodiment supports the golf ball 16 with two different heights in a balanced manner by the short hair bundle 10 and the long hair bundle 12, and the long hair bundle 12 tightens the outer periphery of the golf ball 16. As described above, the golf ball 16 is efficiently and stably supported by pressing with equal force.

  As described above, the long hair bundle applies an equal force for holding the ball around the golf ball 16, so that the golf ball 16 on the golf tee 2 is stably held at the center of the golf tee 2. The golf ball 16 rolls off from the golf tee 2 even when the wind blows or when the base 4 of the golf tee 2 is inserted into the ground or the turf with a slight inclination compared to the conventional golf tee. Hateful.

  FIG. 6 shows the result of verifying that the golf tee 2 stably supports the golf ball 16. FIG. 6 shows the results of measuring the angle at which the ball rolls by gradually tilting the base portion of the golf tee on which the golf ball 16 is placed in a horizontal state. The experiment was conducted with the golf tee 2 of the present example and two types of golf tees as comparative examples. The golf tee of Comparative Example 1 is a golf tee in which hair bundles having a height of 46.0 mm are planted vertically and annularly. The golf tee of Comparative Example 2 is a golf tee in which hair bundles having a height of 28.0 mm are planted vertically and annularly. The drop angle shown in FIG. 5 is an average of the results of three measurements under the same conditions.

  As a result of the measurement, in the golf tee 2 of this example, the golf ball 16 dropped when the pedestal portion 6 was tilted by an average of 18 degrees. On the other hand, in the golf tee of Comparative Example 1, the golf ball 16 dropped when the pedestal was tilted by an average of 14 degrees. In the golf tee of Comparative Example 2, the golf ball 16 dropped when the pedestal portion was tilted by an average of 13 degrees. The golf ball 16 can be held until the golf tee 2 of the present embodiment is tilted more greatly than the golf tees of the comparative example 1 and the comparative example 2 when the golf ball 16 is blown by the wind or when the golf ball 16 is dropped slightly from above. Even when the golf ball 16 dropped on the golf tee 2 is placed on a position deviated from the center of the flocked portion of the golf tee, the golf ball 16 is less likely to roll and more stable. The golf ball can be held.

  Further, the golf tee 2 of the present embodiment can hold the golf ball 16 even when the golf ball 16 is dropped from above the golf tee 2 and placed at a position slightly deviated from the center. FIG. 7 shows the result of verifying how far the golf ball 16 dropped from the center can be held without dropping, in the golf tee 2. For comparison, FIG. 8 shows the result of verifying whether or not the golf ball 16 can be supported under the same conditions with respect to a golf tee in which the height of the hair bundle is uniform and the hair bundle is vertically and annularly implanted. Show. In addition, the length of the hair bundle of the golf tee for comparison is 46 mm shorter than the golf tee 2 by 1 mm.

  The position at which the golf ball 16 is dropped on the golf tee is set at 6 levels at intervals of 2 mm from a distance of 2 mm to 12 mm from the center of the golf tee. Further, the height at which the golf ball 16 is dropped is measured by the height from the tip of the hair bundle of the golf tee, and five levels are set at intervals of 2 mm from 2 mm to 10 mm. Each experiment is performed three times. The experimental results shown in FIGS. 7 and 8 indicate the case where the golf ball 16 is held on the golf tee by ◯ and the case where the golf ball 16 falls from the golf tee by X.

  As shown in FIG. 7, the golf tee 2 of the present example is the first when the height from the tip of the hair bundle is set to 8 mm and the golf ball 16 is dropped to a position of 12 mm from the center of the golf tee 2. The golf ball fell. When the golf ball 16 is dropped from a height lower than that, the ball 16 does not drop at all, and when the golf ball 16 is dropped at a position where the distance from the center is 10 mm or less, It did not fall at all. On the other hand, as shown in FIG. 8, when the golf tee of the comparative example is set to a height of 2 mm from the tip of the hair bundle and the golf ball 16 is dropped to a position of 8 mm from the center of the golf tee 2 The golf ball 16 could not be supported and the golf ball 16 dropped. It is clear from this verification that the golf tee 2 of this embodiment can hold the ball even when the ball is dropped to a position farther from the center. From these results, it was shown that in actual play, even when the golf ball 16 is placed off the golf tee 2, the golf ball 16 is hard to drop and can be held more stably.

  Moreover, in the golf tee 2 of this embodiment, the tip of the short bundle of 8 bundles and the tip of the long bundle of 8 bundles support the golf ball 16 on a point. As a result, the actual area of the contact area between the golf ball 16 and the short hair bundle 10 and the long hair bundle 12 is very small despite being uniformly dispersed and wide. For this reason, the contact resistance between the golf tee 2 and the golf ball 16 of the present embodiment is greatly reduced. Furthermore, the short hair bundle 10 made of polyamide and the long hair bundle 12 made of polypropene cooperate with each other to support the golf ball 16 very efficiently, so that the number of hair bundles is small as in this embodiment. Even if it exists, the golf ball is stable. In addition to the small number of hair bundles, the short hair bundle 10 and the long hair bundle 12 are easily bent when the golf club head comes in contact with the swing, so that even when the player strikes the hair bundle, the reaction force is almost felt. Absent. As a result, the golf tee 2 of the present embodiment can stably support the golf ball 16 as well as a reduction in contact resistance and a feeling of swinging out of the club as compared with the conventional wooden or resin rod-shaped golf tee. Goodness and high stability in the direction of the hit ball are realized, and it is possible to increase the flight distance of the golf ball 16 and to hit the hit ball in the direction intended by the player. In addition, even if the golf tee 2 of this embodiment hits a portion of the hair bundle, it is unlikely that the entire golf tee 2 will fly off the ground or the grass, and the golf tee 2 is unlikely to be lost.

  Further, the golf tee 2 on which the golf ball 16 is placed can be held in a state shown in FIG. 5 so as to be wrapped with one hand, and can be accurately and easily inserted into the ground or turf. When the golf tee 2 is held with the golf ball 16 placed, the long hair bundle 12 that is inclined is regularly elastically deformed so as to open further in the direction inclined from the beginning, so that the player feels uncomfortable with the hand. There is nothing. Further, since the base portion 6 of the golf tee 2 has a truncated cone shape, it is easy to put a finger on the side surface, and the base portion 4 can be surely inserted into the ground or turf up to the lower surface of the base portion 6.

  In the present embodiment, the case where the hair transplantation part 8 is composed of eight short bundles 10 and eight long bundles 12 and each bundle consists of 14 hairs has been described. It is possible to set the number of bundles of hair bundles to be planted more closely to the interval of planting, and to even 10 bundles or more. In addition, it is possible to increase the diameter of the hair to be planted to reduce the number of hairs constituting the hair bundle, or to narrow the diameter of the hair to be implanted to increase the number of hairs constituting the hair bundle. is there.

The golf tee 2 of the present embodiment can stably support the golf ball 16 with a low contact resistance. In addition, the golf tee 2 is a golf tee that has a good feeling of swinging the club and can fly the golf ball 16 in a more stable direction than before.
(Second Example) The golf tee of the present example and the golf tee 2 of the first example are different in the thickness and length of the hair constituting the hair bundle and the angle toward the outer peripheral portion of the long hair bundle. . For short hair bundles, 14 strands of polyamide having a diameter of 0.6 mm are used per bundle. For long hair bundles, 14 hairs having a diameter of 0.4 mm of polypropene are used per bundle. The long hair bundle is inclined 6 degrees in the direction toward the outer peripheral portion of the pedestal portion 6 with respect to the central axis of the golf tee. A short hair | bristle bundle is adjusted so that the height from the base part lower surface when planted may be set to 30.0 mm. A long hair | bristle bundle is adjusted so that the height from the base part lower surface when planted may be 32.0 mm.

The golf tee of the present embodiment uses thick hair having a diameter of 0.6 mm for a short hair bundle and further strengthens the force for supporting the golf ball 16. Since the short hair bundle hardly causes elastic deformation even when the golf ball 16 is placed, the height for holding the ball can be made constant at all times. On the other hand, by using thinner hair having a diameter of 0.4 mm for a long hair bundle and increasing the inclination angle, the long hair bundle causes smooth and uniform elastic deformation to support the golf ball 16. Can do.
Third Embodiment FIG. 9 shows a side view of the golf tee 22 of this embodiment, and FIG. 10 shows a top view of the pedestal portion 26. About the thing of the same structure as 1st Example, the same code | symbol is provided and duplication description is omitted.

  As shown in FIG. 10, 20 flocking holes 36 a to 36 j and flocking holes 38 a to 38 j are virtually concentric with the central axis of the golf tee 22 on the upper surface of the base portion 26 of the golf tee 22 of this embodiment. Are arranged on two concentric circles. The arrangement of the flock holes is schematically shown in FIG. All the cross-sectional shapes of the flock holes in this example are circular with a radius of 1.0 mm. The distances from the center of the flocking holes 36a to 36j to the center of the upper surface of the pedestal 6 are all 10.0 mm. The distances from the center of the flock holes 38a to 38j to the center of the upper surface of the pedestal 6 are all 8.0 mm. That is, the flocking holes 36 a to 36 j and the flocking holes 38 a to 38 j are arranged in an area of 7.0 mm or more and 11.0 mm from the center of the upper surface of the base portion 6. Here, the ten flock holes 36 a to 36 j are inclined at an angle of 2.0 degrees in the obliquely outward direction with respect to the central axis of the golf tee 22.

  The hair transplantation part 28 of the golf tee 22 of the present embodiment has 10 short bundles 30 which are planted one by one in the tufts 38a to 38j and 10 long bundles which are planted one by one in the tufts 36a to 36j. It is composed of a hair bundle 32. In the side view of the golf tee 22 in FIG. 9, four bundles 30a, 30b, 30c, 30d of the ten short bundles 30 are shown, and among the ten long bundles 32, 5 bundles of hair 32a, 32b, 32c, 32d, 32e are shown.

  For the short hair bundle 30, polyamide 0.7 mm diameter hair is used. The number of hairs constituting the hair bundle is twelve. The short hair bundle 30 is vertically fixed to the flock holes 38a to 38j inside the upper surface of the pedestal portion 26 one by one using a flat line, and adjusted so that the height from the lower surface of the pedestal portion is 37.0 mm. The

  For the long hair bundle 32, a hair having a diameter of 0.3 mm of polypropene is used. The number of hairs constituting the hair bundle is 14. The long hair bundle 32 is fixed to the flock holes 36a to 36j near the outer periphery of the pedestal portion 26 one by one using a flat wire. Since the long hair bundle 32a is fixed along the angle of the flock hole, the long hair bundle 32a extends upward while inclining 2.0 degrees outward, and the height from the bottom surface of the pedestal portion is 40. It is adjusted to be 0 mm.

  The golf tee 22 of the present embodiment uses thick hairs for the short hair bundles 30 to further strengthen the force for supporting the golf ball 16. Since the short hair bundle 30 hardly undergoes elastic deformation even when the golf ball 16 is placed, the height for holding the ball can be made constant at all times. On the other hand, by using thinner hair having a diameter of 0.3 mm for the long hair bundle 32, the long hair bundle can smoothly and uniformly undergo elastic deformation. Although the hair of the long hair bundle 32 is thin, by arranging it on the outer side, the inclination angle is reduced, the number of hairs per bundle is increased, and the number of hair bundles to be planted is increased to 10 bundles. By narrowing the distance between the bundle and the hair bundle, a sufficient force is obtained to hold and support the outer periphery of the golf ball 16.

  FIG. 11 shows the result of verifying that the golf tee 22 of this example can hold the ball even when the golf ball 16 is dropped to a position slightly deviated from the center of the flocked portion 28. For comparison, the results of verifying how much the golf ball 16 can be held under the same conditions are shown for a conventional golf tee in which the hair bundle height is uniform and the hair bundle is vertically and annularly planted. 12 comparative examples 2 and FIG. 13 comparative example 3. The length of the hair bundle of the golf tee for comparison is 34 mm shorter than the long hair bundle of the golf tee 22 (Comparative Example 2) and 23 mm shorter than the long hair bundle of the golf tee 22 (Comparative Example). 3).

  As shown in FIG. 11, the golf tee 22 of the present example is the first when the height from the tip of the hair bundle is set to 4 mm and the golf ball 16 is dropped to a position of 12 mm from the center of the golf tee 22. The golf ball fell. When the golf ball 16 was dropped from a height of 10 mm, the ball 16 did not fall from the golf tee 22 and was held on the golf tee 22 if the amount of deviation from the center of the golf tee 22 was 10 mm or less. In addition, when the golf ball 16 is dropped from a height of 2 mm or less, the ball 16 does not fall from the golf tee 22 and is held on the golf tee 22 even when dropped to a position 12 mm away from the center of the golf tee 22. It was.

On the other hand, as shown in FIG. 12, when the golf ball 16 of Comparative Example 2 drops the golf ball 16 from a height 2 mm away from the tip of the hair bundle, the golf ball is positioned 6 mm away from the center of the golf tee. Even when 16 was dropped, the golf ball 16 dropped. Further, in the golf tee of Comparative Example 3, when the golf ball 16 is dropped from a height 8 mm away from the tip of the hair bundle, even when the golf ball 16 is dropped at a position 6 mm away from the center of the golf tee, The golf ball 16 has fallen. As described above, the golf tees of the comparative example 2 and the comparative example 3 are the golf balls 16 even when the golf ball 16 is dropped from a position lower than the golf tee 22 of the embodiment 3 to a position closer to the center. It became clear that it could not be retained. It is clear from this verification that the golf tee 22 of this example can hold the golf ball 16 more stably than the comparative examples 2 and 3 of the conventional product.
(Fourth Example) FIG. 14 schematically shows the arrangement of the flock holes arranged on the pedestal 44 of the golf tee 42 of this example. The golf tee 42 of the present embodiment and the golf tee 2 of the first embodiment differ in the arrangement of the flock holes in the pedestal and the number of hair bundles to be fixed.

  The pedestal 44 of the golf tee 42 of this embodiment has a circular recess 45, flocking holes 46a to 46l whose side walls are inclined 3.0 degrees obliquely outward of the golf tee 42, and vertical flocking holes 48a. .About.48d are provided. The flocking holes 46 a to 46 l and the vertical flocking holes 48 a to 48 d are regularly arranged at predetermined vertices of a regular polygon imagined on the upper surface of the pedestal portion 44.

  The flock holes 46a to 46l into which long hair bundles are planted are the 12 vertices remaining when the four vertices are regularly removed from among the 16 vertices when a regular hexagon is assumed on the upper surface of the pedestal portion 44. It is arranged at the position. As a result, in the long hair bundle fixed to the flock holes 46a to 46l, a collection of hair bundles composed of three bundles constitutes a substantially square shape on the pedestal.

  The vertical flock holes 48a to 48d into which the short hair bundles are flocked are positions of the four vertices regularly removed among the vertices of the regular hexagons that are hypothesized to determine the positions of the flock holes 46a to 46l. Are arranged at a position closer to the center of the pedestal 44. As a result, the four short bundles arranged in the flock holes 48a to 48d are fixed to the positions of the square apexes inside the long bundle.

  For short hair bundles, polyamide hair with a diameter of 0.5 mm is used. The number of hairs constituting the short hair bundle is 16. For long hair bundles, the hair of polypropene having a diameter of 0.5 mm is used. The number of hairs constituting the hair bundle is twelve.

In the golf tee 42 of the present embodiment, when the golf ball 16 is disposed, the load of the golf ball 16 applied to each bundle of short hair bundles becomes uniform, and the load of the golf ball 16 applied to each bundle of long hair bundles. Are all uniform. The golf tee 42 of the present invention can stably support a golf ball in a state where contact resistance is reduced by arranging a short hair bundle and a long hair bundle in a well-balanced manner.
(5th Example) The side view of the golf tee 52 of a present Example is typically shown in FIG. The golf tee 52 according to this embodiment includes a pedestal portion 54 and a flocked portion 8. The structure of the flocked part 8 is the same as that of the first embodiment, and the same reference numerals are given to omit redundant description.

  In the pedestal portion 54, a portion where the hair transplantation portion 8 is provided is formed of resin, wood, or the like having sufficient rigidity to support the hair transplantation portion. The pedestal portion 54 has a substantially flat appearance, and can be used by being embedded in an artificial turf or rubber mat provided with a hole substantially matching the shape of the pedestal portion 54. Moreover, it can attach to the artificial turf or rubber mat which has a hole corresponding to the magnitude | size of the flocked part 8 from a lower side, and can be used in the state which the flocked part 8 protruded from the artificial turf or the rubber mat.

  Since the golf tee 52 is supported by the artificial turf or rubber mat in addition to the base portion 54 being wider than that of the conventional golf tee, the golf tee 52 does not fall down even when placed in a place with some unevenness. Since the golf tee 52 stabilizes the golf ball 16 at two different heights by the long hair bundle 10 and the short hair bundle 12, the pedestal portion 54 of the golf tee 52 is arranged with a slight inclination. Even when the entire portion 8 is slightly inclined, the golf ball 16 is stably supported without rolling down.

As described above, the golf tee 52 of the present embodiment can stably support the golf ball 16 without falling down even if there is no base portion to be inserted into the ground or turf. The golf tee 52 is used to hit the golf ball 16 by using the brush-type golf tee at a place where the brush-type tee has not been improved up to now, that is, on a stone, concrete, driving range, etc. It became possible.
(6th Example) In FIG. 16, the side view of the golf tee 56 of a present Example is shown typically. The golf tee 56 according to this embodiment includes a pedestal portion 58 and a flocked portion 8.

  The pedestal portion 58 of the golf tee 56 according to the present embodiment has a cylindrical shape, and the flocked portion 8 is provided on the upper surface. The pedestal 58 is made of resin or wood having sufficient rigidity. The pedestal portion 58 has a substantially flat appearance, and is used in a state of standing on the ground.

The golf tee 56 according to the present embodiment can support the golf ball 16 in a state where the golf tee 56 is left on the ground even without a base portion to be inserted into the ground or the lawn. The golf tee 56 can be used on a course, and can also be used when practicing with a brush-type golf tee at home or the like.
(7th Example) In FIG. 17, the side view of the golf tee 62 of a present Example is shown typically. The golf tee 62 according to the present embodiment includes a pedestal portion 64, an attachment portion 66, and a flocked portion 8.

  The attachment portion 66 is provided on the lower surface of the pedestal portion, and can be inserted and fixed to a rubber tee fixed to the golf ball supply means of the golf driving range, or can be attached to the ball supply means instead of the rubber tee. It has a shape. The mounting portion 66 in the present embodiment is provided with a convex portion 68 and is fixed to the concave portion of the golf ball supply means. The golf tee 62 attached to the golf ball supply means moves according to the vertical movement of the golf ball supply means, so that the ball is placed on the flocked portion 8.

  The golf tee 62 of the present example has a better swing feeling than the rubber golf tee used in the conventional golf driving range, and hardly damages the golf club. Further, by applying the golf tee 62 of the present embodiment, it becomes possible to use the same golf tee as that used on the golf course at the practice field, and it is possible to practice golf more efficiently.

  The golf tee of this embodiment can change the shapes of the pedestal portion and the attachment portion in accordance with the shape of the attachment portion of the golf ball supply means. FIG. 18 shows an application example in which the shapes of the pedestal part and the attachment part are modified. The golf tee 72 of the application example has a shape suitable for fixing to the convex portion of the golf ball supply means of the driving range. The golf tee 72 has a pedestal portion 74 extending downward, and has a fitting hole 76 having a shape matching the convex portion of the golf ball supply means on the lower surface. The golf tee 72 is fixed to the golf ball supply means by the fitting hole 76.

  As mentioned above, although the specific example of this invention was demonstrated in detail in 1st Example-7th Example, these are only illustrations and do not limit a claim. For example, in the embodiments, golf tees having long hair bundle angles of 2.0 degrees, 3.0 degrees, and 6.0 degrees have been described. However, when the hair bundle is implanted at a position closer to the center, the inclination is inclined. The angle can be appropriately set within a range of 7.0 degrees or less. Similarly, the case where the difference in height between the long hair bundle and the short hair bundle is 2.0 mm and 3.0 mm has been described. By setting them on different concentric circles within a radius of 6 mm or more and 11 mm or less, it is possible to stably support the golf ball even when the difference in height between the tips of the hair bundles is made larger. As described above, the technical elements described in this specification or the drawings exhibit technical usefulness alone or in combination, and are not limited to the combinations described in the embodiments.

  In addition, the technology described in the claims includes various modifications and changes in the material, shape, dimensions, number, arrangement, and the like in the specific examples illustrated above.

  For example, as a method of fixing the hair bundle, in addition to the method of fixing the follicle hole using a flat wire, a method of inserting the hair bundle into the flock hole and embedding with a resin is also possible.

  For example, the structure and shape of the attachment portion for fixing the golf tee to the ball supply means of the golf driving range can be appropriately changed according to the shape of the attachment portion of the ball supply means.
