Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. First, the configuration of the golf tee 1 will be described with reference to FIGS. 1 to 8. The golf tee 1 includes a rod-shaped pin body 10 on which a golf ball is placed, and a plate 20 through which the pin body 10 penetrates. In the present specification, the lower end side of the pin body 10 inserted into the ground at the time of a tee shot is the tip end side, and the upper end side on which the golf ball is placed is the hand side.

The pin body 10 includes a ball pedestal 11 located at the upper end, a pull-out prevention protrusion 13 formed on the tip end side, and an insertion slit 18 formed in the vicinity of the pull-out prevention protrusion 13. The tip of the pin body 10 is sharp so that it can be pierced into the ground, and the pin body 10 has a tapered shape that gradually tapers toward the tip at the tip.

The ball pedestal 11 has a structure in which a golf ball is held at the upper end thereof, and a plurality of protrusions 11a project upward in a bowl shape as a whole, and golf is performed at the upper ends of the plurality of protrusions 11a located on the same plane. The ball can be supported stably. Of course, the shape of the ball pedestal 11 can be changed as appropriate.

The pull-out prevention protrusion 13 is formed near the tip (tip side) separated from the tip of the pin body 10 by a predetermined distance, and is installed so as to protrude at two opposing positions 180 ° apart about the longitudinal axis of the pin body 10. Has been done. The pull-out prevention protrusion 13 functions to prevent the pin body 10 once inserted into the insertion hole 22 of the plate 20, which will be described later, from coming off.

The pull-out prevention protrusion 13 includes a tip-side gentle slope portion 14 located on the tip side and a pull-out prevention steep slope portion 15 formed on the hand side from the maximum protrusion 13a that protrudes most. Here, in the present embodiment, the total length of the pin body 10 is 85 mm, the outer diameter (diameter) is 4.2 mm, and the outer diameter (diameter) of the maximum protruding portion 13a of the pull-out prevention protruding portion 13 is 4.8 mm. The maximum protrusion 13a of the pull-out prevention protrusion 13 protrudes 0.3 mm from the outer surface of the pin body 10.

The tip-side gently inclined portion 14 is a tapered surface inclined at a gentle angle with respect to the outer surface of the pin body 10, and is a portion that gradually narrows from the maximum protruding portion 13a toward the tip. In the present embodiment, the length of the tip side gently inclined portion 14 in the longitudinal direction is 4 mm, and the tip end side end portion of the tip side gently inclined portion 14 is located 12 mm from the tip of the pin body 10.

The pull-out prevention steeply inclined portion 15 is a steeply inclined surface that intersects the outer surface of the pin body 10 at a large angle, and in the present embodiment, it is an R surface (radius of about 0.4 mm) that is obliquely upwardly convex in the front view. It intersects the outer surface of the pin body 10 substantially vertically.

The insertion slit 18 is a slit hole formed on the tip end side of the pin body 10 that horizontally penetrates the pin body 10, and the insertion slit 18 is orthogonal to the opposite direction in which the two pull-out prevention protrusions 13 face each other. It penetrates the pin body 10 in the direction of

The insertion slit 18 is formed at a position overlapping with the pull-out prevention protrusion 13 in the longitudinal direction. The width of the insertion slit 18 is 1 mm, the length in the longitudinal direction is 10 mm, and the tip end portion in the longitudinal direction is located 10 mm from the tip of the pin body 10.

In the region where the insertion slit 18 of the pin body 10 is formed, the outer surface of the pin body 10 is inside in a direction horizontally orthogonal to the penetrating direction of the insertion slit 18 (opposite directions of the two retaining protrusions). When pressed to, the insertion slit 18 is deformed so that the width becomes smaller, and the pin body 10 can be made thinner. In the present embodiment, the thickness can be reduced by a maximum of about 1 mm in the direction orthogonal to the penetration direction.

In the present embodiment, the length of the insertion slit 18 in the longitudinal direction is longer than that of the pull-out prevention protrusion 13, and the insertion slit 18 is installed so as to overlap the entire formed region in the longitudinal direction of the pull-out prevention protrusion 13. Therefore, as will be described later, when the pin body 10 is inserted into the insertion hole 22 of the plate 20, the maximum protruding portion 13a of the pull-out prevention protruding portion 13 can be temporarily thinned and inserted.

The plate 20 includes a circular plate-shaped elastic sheet 21 formed of an elastic body and a tubular reinforcing member 25. An insertion hole 22 through which the pin body 10 passes is formed in the center of the elastic sheet 21. The elastic sheet 21 is formed of an elastic synthetic resin, and in this embodiment, a transparent silicone gel is used. The elastic sheet 21 has a diameter of 40 mm, and the insertion hole 22 has an inner diameter of 4.5 mm.

The tubular reinforcing member 25 is a metal (stainless steel) reinforcing member having a substantially cylindrical shape as a whole, and is installed in the elastic sheet 21 so as to surround the insertion hole 22. The tubular reinforcing member 25 has a two-stage structure including a small-diameter upper cylindrical portion 25a and a large-diameter lower cylindrical portion 25b. The boundary portion between the upper cylindrical portion 25a and the lower cylindrical portion 25b is connected by a middle flat portion 27 which is in the shape of a horizontal strip plate.

A reinforcing insertion hole 28 located at substantially the same position as the insertion hole 22, which is one size smaller than the outer diameter of the upper cylindrical portion 25a, is formed in the center of the upper surface of the upper cylindrical portion 25a, and the pin body 10 is reinforced and inserted. It is inserted into the hole 28. The inner diameter of the reinforcing insertion hole 28 is about 4.5 mm.

As shown in FIGS. 5 and 6, the inside of the tubular reinforcing member 25 is a hollow portion 29 in which the elastic sheet 21 does not exist. That is, the elastic sheet 21 is installed so as to cover the outer surface such as the upper surface, the outer surface, and the lower surface of the tubular reinforcing member 25.

When the pin body 10 is inserted into the insertion hole 22 of the plate 20 from above from the tip, the diameter of the pin body 10 is 4.2 mm, whereas the inner diameter of the reinforcing insertion hole 28 is 4.5 mm. The main body 10 can be inserted into the reinforcing insertion hole 28, but since the maximum diameter of the maximum protruding portion 13a of the retaining protrusion 13 is 4.8 mm, which is larger than the inner diameter of the reinforcing insertion hole 28, the maximum protruding portion 13a is left as it is. Is caught in the reinforcing insertion hole 28 and cannot be inserted. Here, the maximum diameter is the size of the longest portion of the retaining protrusion 13 in the radial direction (horizontal direction orthogonal to the longitudinal direction).

However, in the present embodiment, the insertion slit 18 is formed inside the installation area of the pull-out prevention protrusion 13, and at the time of insertion, the tip-side gently inclined portion 14 of the pull-out prevention protrusion 13 is the peripheral edge of the reinforcing insertion hole 28. When pushed inward in the radial direction by contacting with, the insertion slit 18 is deformed so as to become smaller in the width direction (diameter direction) (see FIG. 6).

As a result, the diameter of the portion of the maximum protruding portion 13a is also reduced, and the maximum protruding portion 13a can pass through the reinforcing insertion hole 28. The width of the insertion slit 18 is 1 mm, and the maximum protrusion 13a can be as thin as about 1 mm, that is, as thin as about 3.8 mm.

As shown in FIG. 7A, once the pin body 10 is inserted into the plate 20 until the entire pull-out prevention protrusion 13 passes through the reinforcing insertion hole 28, the portion of the pin body 10 having a diameter of 4.2 mm is formed. It is slidable with respect to the reinforcing insertion hole 28 having an inner diameter of 4.5 mm, and the pin body 10 can be inserted into the insertion hole 22 until the lower surface of the ball pedestal 11 contacts the plate 20.

That is, once the pin body 10 is inserted into the insertion hole 22, the pin body 10 and the plate are located between the position where the plate 20 contacts the dropout prevention protrusion 13 and the position where the plate 20 contacts the ball pedestal 11. It becomes relatively slidable in a state where the 20 is connected through the penetration.

Further, in the present embodiment, the inner diameter (4.5 mm) of the reinforcing insertion hole 28 (insertion hole 22) is slightly larger than the outer diameter (4.2 mm) of the pin body 10, and there is play in the insertion connection portion, so that the pin body 10 is swingable in all directions with respect to the plate 20 within a predetermined inclination angle.

On the other hand, when the inserted pin body 10 moves in the direction of exiting from the insertion hole 22, the ejection prevention steep slope portion 15 on the hand side (upper side) of the maximum protrusion 13a having a diameter of 4.8 mm is reinforced from below. It collides with the peripheral edge of 28 (insertion hole 22) and cannot move in the direction of exiting further.

At this time, even if the pull-out prevention steeply inclined portion 15 comes into contact with the lower edge of the reinforcing insertion hole 28, the inclination angle of the pin body 10 with respect to the outer surface is large, and in particular, the portion of the pin body 10 rising from the outer surface is approximately 90. Since the temperature is set to °, the force in the direction of pushing the pull-out prevention steeply inclined portion 15 inward in the radial direction, that is, in the direction of slightly deforming the insertion slit 18, hardly acts.

Therefore, once the pin body 10 is inserted into the insertion hole 22 of the plate 20, it will not easily come off unless the pull-out prevention protrusion 13 is artificially deformed. The shape of the pull-out prevention steeply inclined portion 15 located at the hand side end of the pull-out prevention protrusion 13 can be changed as appropriate, and may be a flat surface perpendicular to the surface of the pin body 10, and the insertion hole 22 of the plate 20 may be formed. The shape may be such that the force for deforming the insertion slit 18 and thinning the pull-out prevention protrusion 13 does not act when colliding with the peripheral edge.

The configuration of the golf tee 1 has been described above, but subsequently, the usage mode of the golf tee 1 will be described with reference to FIG. As shown in the figure, the golf tee 1 is used by inserting it into the tee ground at the time of a tee shot.

When the golf tee 1 is inserted into the ground, the pin body 10 is inserted into the ground to a predetermined depth so that the golf ball 5 placed on the ball pedestal 11 has a desired height. At this time, since the plate 20 located between the ball pedestal 11 and the pull-out prevention protrusion 13 is slidable in the longitudinal direction with respect to the pin body 10, it does not interfere with the ground when it is inserted into the ground. It can be appropriately slid to the contact position.

When the golf tee 1 is set, when the lawn of the teeing ground enters the hollow portion 29 of the tubular reinforcing member 25 of the plate 20 that comes into contact with the ground, the pin body 10 and the plate 20 are stably supported by the lawn. Will be done.

Subsequently, when the head of the golf club collides with the golf tee 1, particularly the ball pedestal 11 of the pin body 10 in the horizontal direction at the time of a tee shot, the pin body 10 comes out of the ground and is blown in the collision direction.

At this time, the pin body 10 is inserted into the insertion hole 22 and connected to the plate 20, and the plate 20 also flies integrally with the pin body 10. At this time, since the plate 20 has a certain mass and also receives air resistance, the flight distance of the golf tee 1 becomes short.

Further, even if the skipped golf tee 1 falls to the ground, the pin body 10 and the plate 20 intersect at a predetermined angle (within a predetermined swing angle), so that the pin body 10 is horizontal to the ground. Since the pin body 10 and the plate 20 project upward without lying down, it is easy to find even if the pin body 10 or the plate 20 falls on a grassland or the like.

Further, when the head of the golf club collides with the golf tee 1, an impact is applied to the connecting portion between the pin body 10 and the plate 20, but there is play in the connecting portion between the pin body 10 and the plate 20, so the pin body 10 By swinging with respect to the plate 20, the impact can be released and damage can be prevented.

Subsequently, a modified example of the present embodiment will be described. First, the pin bodies 10 ″ and 10 ″ according to the modified examples 1 and 2 will be described with reference to FIG. FIG. 9A is a front view of the pin body 10 ′ according to the first modification. In the first modification, the structure of the pull-out prevention protrusion 13'is different from that of the above-described embodiment, and the pull-out prevention protrusion 13'is a male screw.

The maximum diameter of the male screw of the pull-out prevention protrusion 13'is larger than the inner diameter of the reinforcing insertion hole 28 of the tubular reinforcing member 25, and the male screw cannot pass through the reinforcing insertion hole 28 simply by inserting it straight, but the pin body 10 It is configured so that it can pass through the reinforcing insertion hole 28 by screwing in while twisting. Therefore, the same effect as that of the above-described embodiment is obtained in the present modification 1.

FIG. 9B is a front view of the pin body 10 ″ according to the second modification. In the second modification, the structure of the insertion slit 18'is different from that of the insertion slit 18 of the above embodiment, and the insertion slit 18'is formed up to the tip of the pin body 10'', and the pin body 10'' is formed. The tip of is divided into two.

According to the second modification, the same effect as that of the above embodiment is obtained, and the insertion slit 18'is formed up to the tip, so that the tip of the pin body 10'is easily thinned at the time of insertion. , The pin body 10 ″ can be more easily inserted into the reinforcing insertion hole 28.

Next, the plate 20'according to the modified example 3 will be described with reference to FIG. FIG. 10 is a cross-sectional view of the plate 20'according to the third modification. In the third modification, the elastic sheet 21'is different from the elastic sheet 21 of the above embodiment, and the elastic sheet 21'is also installed inside the tubular reinforcing member 25.

In the third modification, since the elastic sheet 21'also exists inside the reinforcing insertion hole 28 of the tubular reinforcing member 25, the pin body 10 to be inserted is not the inner edge of the tubular reinforcing member 25, but the elastic sheet 21. Contact'.

Therefore, according to the third modification, the same effect as that of the above embodiment is obtained, and when the head of the golf club collides with the golf tee 1, it acts on the connecting portion between the pin body 10 and the plate 20'. The impact can be softened by the elastic sheet 21'.

Subsequently, the pin body 10 ″ ″ according to the modified example 4 will be described with reference to FIGS. 11 and 12. FIG. 11 is a front view of the pin body 10 ″ ″ according to the modified example 4. FIG. 12 is an enlarged cross-sectional view of the connected portion after insertion according to the modified example 4.

In the present modification 4, as a second pull-out prevention protrusion located between the plate 20 and the pull-out prevention protrusion 13 after insertion, an elastic body such as an elastic resin or elastic rubber (for example, elastic rubber) is attached to the pin body 10''''. , NBR, silicone gel, polyurethane, polypropylene, polyethylene, EVA, etc.), which is a tubular member, characterized in that a second dropout prevention protrusion 16 is installed.

The second drop-out prevention protrusion 16 has a two-stage cylindrical shape, with a small diameter portion on the upper side and a large diameter portion on the lower side, but the cylinder holes penetrating up and down have the same inner diameter. Since the inner diameter of the cylinder hole is smaller than the outer diameter of the pin body 10 ″, the second pull-out prevention protrusion 16 is movable in the axial direction with respect to the pin body 10 ″ penetrating the inside of the cylinder. Moreover, it can be fixed at a predetermined position in the axial direction of the pin body 10 ′ ″ penetrating the inside of the cylinder by tightening an elastic force.

According to the fourth modification, the pin body 10'' is further provided with a second pull-out prevention protrusion 16 having an outer diameter larger than the maximum diameter of the pull-out prevention protrusion 13 in addition to the pull-out prevention protrusion 13. Therefore, it is possible to more reliably prevent the pin body 10 ′ ″ inserted into the insertion hole 22 of the plate 20 from coming off.

Further, since the pull-out prevention protrusion 13 is located on the tip side of the second pull-out prevention protrusion 16, the second pull-out prevention protrusion 16 that is movable with respect to the pin body 10'''' is from the pin body 10''''. It can also be prevented from coming off.

Further, the second pull-out prevention protrusion 16 is an elastic body, and as shown in FIG. 12B, even if the pin body 10'''' is tilted with respect to the plate 20, the pin body 10'''' and the cylinder By interposing the second pull-out prevention protrusion 16 of the elastic body between the shape reinforcing member 25, the pin body 10'''strongly collides with the metal tubular reinforcing member 25 and is damaged. Can be prevented.

In particular, if the head of the club hits the pin body 10 ″ during a tee shot, the pin body 10 ″ may be strongly pressed against the tubular reinforcing member 25 and break, but the pin body 10 and the tubular shape Such damage can be prevented by interposing the second pull-out prevention protrusion 16 between the reinforcing member 25 and the reinforcing member 25.

Subsequently, the second embodiment of the present invention will be described with reference to FIGS. 13 and 14. Since the golf tee 2 according to the second embodiment has the same configuration as the golf tee 1, the same name will be given to the same configuration, the description will be omitted, and different configurations will be mainly described.

The golf tee 2 includes a rod-shaped pin body 30 on which the golf ball 5 is placed, and a plate 40 through which the pin body 30 penetrates. The pin body 30 includes a ball pedestal 31 and a pull-out prevention rubber cylinder 33 installed on the tip side as a pull-out prevention protrusion, and does not include the insertion slit 18 as in the first embodiment.

The pull-out prevention rubber cylinder 33 is a cylindrical member formed of an elastic body, and since its inner diameter is slightly smaller than the outer diameter of the pin body 30, it can move in the axial direction of the pin body 30 penetrating the inside of the cylinder. In addition, the pin body 30 penetrating the inside of the cylinder can be fixed at a predetermined position in the axial direction by an elastic force.

The plate 40 includes a circular plate-shaped elastic sheet 41 formed of an elastic body and a tubular reinforcing member 45. An insertion hole 42 through which the pin body 30 passes is formed in the center of the elastic sheet 41.

The tubular reinforcing member 45 is a reinforcing member formed of an elastic body such as an elastic resin or elastic rubber having a substantially cylindrical shape as a whole (for example, made of NBR, silicone gel, polyurethane, polypropylene, polyethylene, EVA, etc.). It is installed in the elastic sheet 41 so as to cover the insertion hole 42. The tubular reinforcing member 45 has a circumferential groove 46 formed in the middle step portion in the vertical direction, and the middle step portion is narrowed.

By fitting the peripheral edge of the insertion hole 42 of the elastic sheet 41 into the circumferential groove 46, the tubular reinforcing member 45 is fixed around the insertion hole 42 of the elastic sheet 41. Therefore, the upper portion 45a of the tubular reinforcing member 45 covers the upper surface of the peripheral edge of the insertion hole 42 of the elastic sheet 41, and the lower portion 45b also covers the lower surface of the peripheral edge of the insertion hole 42 of the elastic sheet 41.

When using the golf tee 2, the pin body 30 is passed through the insertion hole 42 of the plate 40 from the tip with the removal prevention rubber cylinder 33 removed, and then the removal prevention rubber cylinder 33 is passed from the tip side to the pin body 30. Fit and fix in place.

Then, the removal prevention rubber cylinder 33 is fixed at a predetermined position of the pin body 30 so as to tighten the pin body 30 by elastic force, and even if the plate 40 tries to come off from the pin body 30, the peripheral edge of the insertion hole 42 is prevented from coming off. It collides with the rubber cylinder 33 and cannot be pulled out.

According to the second embodiment, the same operation and effect as that of the first embodiment is obtained, and it is not necessary to integrally mold the pull-out prevention protrusion 13 with the pin body 30, and the pin of the conventional golf tee is used as the pin body 30. It can be diverted. That is, if the plate 40 is combined with the pin of a conventional golf tee, the golf tee 2 according to the present embodiment can be made.

Subsequently, the modified examples 5 and 6 of this embodiment will be described with reference to FIG. FIG. 15 (a) is a diagram showing the configuration of the golf tee 2 ″ according to the modified example 5, and FIG. 15 (b) is a diagram showing the configuration of the golf tee 2 ″ according to the modified example 6.

In the second modification 5 and 6, similarly to the modification 4 of the first embodiment described above, the second modification is located between the plate 40 and the rubber cylinder 33 to prevent the pin from coming off after being inserted into the pin body 30', 30''. The second pull-out prevention protrusions 36, 36', which are tubular members formed of an elastic body, are installed as the pull-out prevention protrusions.

The outer diameters of the second pull-out prevention protrusions 36, 36'are larger than those of the pull-out prevention rubber cylinder 33. Further, since the inner diameter of the second pull-out prevention protrusion 36, 36'is slightly smaller than the outer diameter of the pin bodies 30', 30', the second pull-out prevention protrusion 36, 36'is inside the cylinder. It is movable in the axial direction with respect to the pen bodies 30'and 30'' penetrating, and can be fixed at a predetermined position in the axial direction by an elastic force.

Therefore, according to the present modifications 5 and 6, the same action and effect as those of the present embodiment are obtained, and by providing the two pull-out prevention protrusions 33 and 36, the same action and effect as the above-mentioned modification 4 is obtained.

Although the embodiments of the present invention have been described above including modifications, the embodiments of the present invention are not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention. Is. For example, the size and shape of each member constituting the golf tee can be changed as appropriate.
