Description

  The present invention relates to a golf tee for practice.

  Conventionally, when performing golf practice, for example, a golf mat that is a mat imitating a lawn and a practice golf tee (see Patent Document 1) attached to the golf mat are used.

The golf tee for practice is a state in which the golf ball is lifted from the ground to a predetermined height by placing the golf ball on the tip thereof.
Among practice golf tees, a practice golf tee called “Hesso tee” includes, as shown in FIG. 11, a bottom plate portion 1 that is placed on the ground, and a cylinder that stands vertically with respect to the bottom plate portion. And a golf ball support portion T having a shape.
By placing the golf ball on the tip of the golf ball support portion T, the golf ball is lifted from the ground by a certain height.
JP 2005-137621 A

However, since golf tees are usually pierced into the ground and used at golf course sites, there is little resistance to impact when a golf club is shaken. However, conventional practice golf tees are attached to a golf mat and impact is low. At the moment, a large resistance is generated.
Moreover, since the golf ball support portion of the practice golf tee is cylindrical, it is relatively poor in flexibility and hard.
Therefore, the resistance at the moment of impact is even greater.

On the other hand, the appropriate height of the practice golf tee used varies depending on the type of club used, such as wood or iron. Therefore, golfers need to purchase practice golf tees for each club.
However, since commercially available practice golf tees are standard products, the types of height are limited.
Therefore, in the unlikely event that the height of the purchased practice golf tee does not fit the golfer, the golfer must cut the practice golf tee himself and adjust the practice golf tee to an appropriate height. It was.

However, the golf ball support portion of the practice golf tee is cylindrical with a certain thickness and is made of vulcanized rubber, so it is hard and it is not always easy to cut the golf ball support portion.
In addition, even if it is cut, the state of the cut surface becomes distorted and the golf ball spills down, and there is a problem that the golf ball cannot be stably placed on the golf ball support portion.

  In addition, the conventional practice golf tee has no mark indicating the length of the golf ball support portion, and the golfer cannot accurately cut the practice golf tee to a desired height.

The present invention has been developed to solve the above problems.
That is, an object of the present invention is to provide a golf tee in which the resistance at the moment of impact is as small as possible and the height can be easily adjusted.

  As a result of intensive studies based on the background of the problems as described above, the present inventor has provided the above-mentioned problems by providing a plurality of support pillars in a ring shape on the bottom plate part and providing a connecting part for connecting them. The present invention has been completed based on the findings.

That is, according to the present invention, (1) a plurality of support columns are vertically and annularly provided on the bottom plate, and a connecting portion for connecting adjacent support columns is formed integrally with the support column. The practice golf tee is a practice golf tee in which a plurality of the connecting portions are annularly formed at predetermined intervals along the longitudinal direction of the support post .
In the present invention, the “ring” is a concept including not only a perfect circle but also a closed figure such as an ellipse or a polygon.

The present invention, (2) the distal end of the strut, the inclined surface inclined in the direction downward toward the center of the bottom plate portion is formed (1) consists in practice golf tee as claimed.

Further, the present invention provides ( 3 ) the practice golf tee according to the above (1), wherein the column part and the connecting part are integrated with each other up to a certain height on the bottom plate part to form a cylindrical integrated part. Exist.

The present invention, (4) the lower surface of the connecting portion, the are inclined in the direction downward toward the center of the bottom plate (1) consists in practice golf tee as claimed.

The present invention also resides in ( 5 ) the golf tee for practice according to the above (1), which is formed of a thermoplastic elastomer, synthetic rubber or natural rubber.

Moreover, this invention exists in the separation golf tee cut | disconnected and cut | disconnected from the lower surface of the said connection part in the golf tee of ( 6 ) said (1) description.

In addition, as long as the objective of this invention is followed, the structure which combined suitably said (1) to ( 6 ) is also employable.

  In the golf tee for practice of the present invention, a plurality of support columns are vertically and annularly provided on the bottom plate, and a connecting portion for connecting the adjacent support columns is formed integrally with the support column. Therefore, a plurality of through windows are inevitably formed by the support portions and the connecting portions.

  By forming the through window, the flexibility of the golf ball support portion on which the golf ball is placed is increased, and the resistance generated at the moment of impact is reduced as much as possible.

Since a plurality of connecting portions are provided at predetermined intervals along the longitudinal direction of the support column, the golfer can easily grasp the height after cutting with reference to the connecting portions.
In addition, the golfer can easily cut off the practice golf tee simply by cutting the strut along the connecting portion.

Since the lower surface of the connecting part is inclined toward the center part of the bottom plate part, the golfer can incline the cutting surfaces of all the supporting pillars at the same inclination angle by cutting the supporting part along the lower surface of the connecting part. Can do.
Also, the golfer can make the height of the cut surface from the ground the same overall.
As a result, the golf ball is stably placed on the practice golf tee after cutting.

Since the inclined surface which inclines toward the center part of the baseplate part is formed in the front-end | tip part of a support | pillar part, when a golf ball is mounted in the said front-end | tip part, a golf ball is supported only by the edge of the said front-end | tip part. It is done.
As a result, the frictional force between the tip and the golf ball is reduced.

Since the column portion is integrated to form a cylindrical integrated portion, only the portion of the golf ball support portion has increased rigidity.
As a result, when the golf ball is placed on the golf ball support portion, the golf ball support portion can maintain an upright state without causing buckling due to the weight of the golf ball.

[First embodiment]
An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a golf tee for practice according to the present embodiment, FIG. 2 is a front view and a top view of the golf tee for practice according to the present embodiment, and FIG. 3 is shown in FIG. FIG. 4 is a cross-sectional view taken along line AA shown in FIG. 4 and FIG. 4 is a cross-sectional view taken along line BB shown in FIG.

As shown in FIG. 1, a golf tee for practice A according to this embodiment includes a flat bottom plate portion 1 placed on the ground and a plurality of standing golf balls A on the bottom plate portion 1 (in the figure, 8) strut portions 2 and a connecting portion 3 for integrally connecting the strut portions 2 to each other.
In addition, it is preferable that the fixing hole E for fixing the golf tee A for practice which concerns on this embodiment to the ground is formed in the baseplate part 1. As shown in FIG.

Each support column 2 is erected in an annular shape from the bottom plate 1 and forms a golf ball support T for placing a golf ball on the tip.
At this time, it is preferable that each support | pillar part 2 is erected at equal intervals.
The golf balls are stably placed on the tips of the golf ball support portions T by the support portions 2 being erected at equal intervals.

The number of support columns 2 erected on the bottom plate 1 is not particularly limited, but both the flexibility of the golf ball mounting portion T and the stability when the golf ball is mounted on the golf ball support portion T. From the viewpoint, it is preferable that the number is 3 to 10.
In other words, when the number of the support portions 2 is less than 3, the golf ball is hardly stably placed on the tip portion 21 of the support portion 2.
On the other hand, when the number of the support portions 2 is more than 10, the flexibility of the golf ball support portion T is lowered, and the resistance force at the time of impact is increased.

Immediately above the bottom plate portion 1 is formed a cylindrical integrated portion 4 in which the support portions 2 are integrated.
By forming the cylindrical integrated portion 4 below the golf ball support portion T, when the practice golf tee A is inserted into the golf mat, the golf ball support portion T stably maintains an upright state.
That is, the bendability of the cylindrical integrated portion 4 is smaller than that of the column portion 2 formed above the cylindrical integrated portion 4 and has so-called rigidity.
When the practice golf tee A is attached to the golf mat, the practice golf tee A (particularly the support post 2) is accurately held in the hole of the golf mat because the cylindrical integrated portion 4 is not easily deformed (FIG. 1). reference).

An inclined surface 22 is formed at the distal end portion 21 of the support column portion 2 so as to be inclined toward the center portion of the bottom plate portion 1 (see FIGS. 3 and 4).
FIG. 5 is a view showing a state in which a golf ball is placed on the practice golf tee of FIG.
As shown in FIG. 5, the inclined surface is formed at the tip portion 21, so that the golf ball is supported by the outer edge of each column portion 2 when the golf ball is placed on the tip portion 21.
Therefore, the contact area between the golf ball and the practice golf tee A is reduced as much as possible, and the frictional force therebetween is reduced.

Here, the inclination angle of the inclined surface 22 is preferably a depression angle of 65 ° or more and a depression angle of 75 ° or less.
When the inclination angle of the inclined surface 22 is smaller than the depression angle 65 °, the golf ball is likely to come into contact with the inclined surface 22 when the golf ball (usually used) is placed on the tip portion 21.
When the inclination angle of the inclined surface 22 is larger than the depression angle of 75 °, the tip end portion 21 is extremely tapered, and the supporting force for supporting the golf ball is reduced. Therefore, it becomes difficult for the golf ball support portion T to support the golf ball.

Here, the diameter D of the ring formed by the column groups 2 is preferably 8 mm or more and 20 mm or less (see FIG. 2A).
When the diameter D is smaller than 8 mm, the support stability of the golf ball is deteriorated, and when the diameter D is larger than 20 mm, the resistance to the golf ball is increased.
Further, if the diameter D is larger than 20 mm, it is difficult to install the golf mat on the market.

On the other hand, the connecting part 3 is for connecting the support parts 2 to each other, and is formed in an annular shape integrally with the support part 2 in a direction perpendicular to the longitudinal direction of the support parts 2 (hereinafter referred to as “circumferential direction”). (See FIG. 1).
A plurality of through windows W are inevitably formed in the golf ball support portion T by the connection portion 3 being formed in the support portion 2 in an annular shape.
By forming this through window W, the flexibility of the golf ball support portion T is increased, and the resistance at the time of impact is reduced.

It is preferable that a plurality of the connecting portions 3 are formed at predetermined intervals (for example, 10 mm intervals) along the longitudinal direction of the column portions 2.
By forming the connecting portion 3 at a predetermined interval, the connecting portion 3 serves as a standard when cutting the practice golf tee A. Therefore, the golfer can easily grasp the length of the golf ball support portion T after cutting, that is, the height at which the golf ball is lifted from the ground.

The lower surface of the connecting portion 3 is inclined in a direction of descending toward the center portion of the bottom plate portion 1 (see FIG. 4). The golfer can easily make the inclination angle of the cut surface of each support column 2 the same by cutting the support column 2 along the lower surface of the connecting portion 3.
Like the inclination angle of the inclined surface 22, the inclination angle of the lower surface of the connecting portion 3 is preferably a depression angle of 65 ° or more and a depression angle of 75 ° or less.

  The golf tee A for practice according to the present embodiment is manufactured by injection molding using an elastomer such as a thermoplastic elastomer, a synthetic rubber, or a natural rubber, which is excellent in shape restoration, but the manufacturing method is not limited to this. .

The golf tee A for practice according to the present embodiment manufactured from a thermoplastic elastomer has a greater flexibility than the golf tee A for practice made of vulcanized rubber.
Further, the practice golf tee A made of a thermoplastic elastomer is easier to cut than the vulcanized rubber, so that the height can be easily adjusted.

FIG. 6 is an explanatory diagram illustrating a usage example when the golf tee for practice according to the present embodiment is used together with a golf mat.
As shown in the drawing, the practice golf tee A according to the present embodiment is attached by being inserted from the back side of the golf mat 5 into a hole H formed in the golf mat 5 imitating the lawn of a golf course.
In this state, the golf ball B is placed on the tip of the golf ball support portion T.
When the golf ball B is placed on the tip of the golf ball support portion T, the golf ball B is lifted up to the height L of the support portion 2.

Next, FIG.7 and FIG.8 is explanatory drawing which shows the example of a cutting | disconnection of the golf tee for practice which concerns on this embodiment in a cross section.
FIG. 7 shows a state before cutting, and FIG. 8 shows a state after cutting.
As shown in FIG. 7, as a cutting example of the practice golf tee A according to this embodiment, there is a method of cutting along the lower surface of the connecting portion 3.

By cutting along the lower surface of the connection part 3, as shown in FIG. 8, the front-end | tip part of the golf tee A for practice after cut | disconnecting can also be made into the state inclined.
Moreover, by cutting along the lower surface of the connection part 3, the situation where the height of a cut differs for every support | pillar part and it becomes distorted as a whole can be avoided.
The portion cut and separated here can be used independently as the separation golf tee C.

FIG. 9 is an explanatory view showing a state where the separated golf tee C is used alone as a golf tee.
As shown in the figure, the separated golf tee C has a shape in which the connecting portion is exposed as it is, so that it can be used as a small golf tee (for example, for a short course) by being placed on the ground.

  That is, when the ground is stable, as shown in FIG. 9 (a), the tip of the support golf ball C is directed upward, and a golf ball is placed on the tip.

When the ground is unstable, as shown in FIG. 9B, the separated golf tee C is placed on the ground with the tip portion of the support portion facing downward.
Thus, the separated golf tee C has an advantage that it can be used upside down.

FIG. 10 is a front view showing a state in which the practice golf tee and the separation golf tee according to the present embodiment are fitted.
As shown in the figure, the separation golf tee C is temporarily held by the practice golf tee A by inserting the support C1 of the separation golf tee C between the pillars 2 of the practice golf tee A according to this embodiment. The

  By temporarily holding the separation golf tee C and the practice golf tee A for storage or carrying, it is convenient to avoid the separation golf tee C being lost.

Although the present invention has been described above, the present invention is not limited to the embodiments, and various modifications can be made.
For example, various shapes such as a rectangular shape and a circular shape can be adopted as the shape of the support column.
In that case, the through window W has a different shape.
The size of the cylindrical integrated portion in the golf ball support portion is appropriately determined from the viewpoint of the mounting stability to the golf mat and the flexibility of the golf ball support portion.
