Description

  The present invention relates to a golf practice mat, and more specifically, a golf practice mat provided with a rough artificial turf part and a fairway artificial turf part having a turf length shorter than that of the rough artificial turf part on a substrate part. About.

For golf enthusiasts, the natural rough conditions on the course are extremely varied, and it is necessary to practice in accordance with those situations on a daily basis.
In general, on the course, there are many people who are not good at taking shots in a rough state where the turf is deep.
This is because the club heads such as irons are entangled with grass leaves, and resistance is required, so it is necessary to practice in the rough.

Usually, golf shots are practiced at a golf practice field or at home. In this case, a golf ball is placed on a practice mat to practice a shot.
It is effective to practice in places other than the actual golf course in a rough state simulating a natural golf course.
For this reason, various practice mats similar to the rough and fairway conditions have been developed.

As such practice mats, for example, those provided with artificial turf as disclosed in Japanese Utility Model Publication No. 62-50680, Japanese Utility Model Publication No. 63-201563, Japanese Utility Model Publication No. 3-16973, etc. are provided. ing.
In Japanese Utility Model Publication No. 62-50680, a plurality of turf sheets in which artificial turf longer than the diameter of a golf ball is planted are arranged in a plane on the substrate surface and are detachably fitted inside the frame-like frame body. A rough practice mat is shown (see Patent Document 1).

  Japanese Utility Model Laid-Open No. 63-201563 discloses a golf practice in which the matte foot of the follow-through side is longer than that of the take-back side so that the club head falls down and returns. A stepped mat is shown (see Patent Document 2).

Furthermore, Japanese Utility Model Laid-Open No. 3-16973 discloses a golf practice mat provided with both artificial turf with uneven turf length and uniform artificial turf (see Patent Document 3).
However, these golf practice mats are certainly made to resemble a natural rough, but the turf leaves are just a length similar to the rough, and the club head is entangled naturally. It is different from turf, and it is not possible to reproduce the so-called natural rough feeling.

In view of this, a golf practice mat capable of obtaining a hit feeling resembling a rough state as much as possible has been developed by the present applicant (see Patent Document 4).
The golf practice mat described in Patent Document 4 has artificial turf leaf widths randomly formed, and can provide a unique feel and turf feel similar to natural rough conditions. .
In addition, this golf practice mat has a lawn with a relatively long lawn and a lawn with a relatively short lawn, so naturally it is suitable for both rough and fairway practice on a golf course. be able to.

As described above, various functional improvements have been made for golf practice mats to improve practice efficiency.
However, in any of the conventional techniques, the address practice function has been forgotten as a golf practice mat.
In other words, in all of the conventional golf practice mats described above, the artificial turf is planted in a rectangular area, so that a golf practitioner can easily address compared to an address on an actual golf course. Can do it.
That is, by matching one side of the rectangular grass portion toward the target, it is possible to easily perform an address that matches the target.
However, for practice, it is preferable that it is difficult to perform addressing, and this is more likely to be practiced for address acquisition on an actual golf course as a golf practitioner.
This point has not been solved.

The present invention has been made on the basis of such a background art, and can overcome the conventional problems in a golf practice mat.
That is, the present invention includes a rough artificial turf portion and a fairway artificial turf portion having a turf length shorter than that of the rough artificial turf portion, which is difficult to address, in other words, for golf practice where address practice is possible. The purpose is to provide a mat.

  Thus, as a result of intensive research on the background of such problems, the present inventor made it difficult to address by making the rough artificial turf part and the artificial turf part for fairway into a curved surface shape, and the above problem The present inventors have found that the problems can be solved, and have completed the present invention based on this finding.

That is, the present invention is (1) a golf practice mat used for practice of golf having a substrate portion and an inclined support spacer for inclining the substrate portion with respect to a horizontal plane . A rough artificial turf portion and a fairway artificial turf portion having a turf length shorter than that of the rough artificial turf portion, the artificial turf portion for rough and the artificial turf portion for fairway are respectively a wide portion and the wide portion A wide portion of the rough artificial turf portion and the narrow portion of the fairway artificial turf portion are arranged correspondingly, and the narrow width of the artificial turf portion for rough And the wide portion of the artificial turf for fairway are arranged corresponding to each other, the outer shape of the artificial turf for rough and the artificial turf for fairway is formed in a curved shape, and the base plate has a trapezoidal cross section. A recess for fitting the inclined support spacer is formed, The central parts resides in a golf practice mat projections are formed to support one side of the inclined support spacer fitted in the recess.

  Moreover, this invention exists in the mat | matte for golf practice as described in said (1) by which the external shape of the said board | substrate part is formed in curve shape (2).

  The present invention also resides in (3) the golf practice mat according to (1), wherein the artificial turf planted in the rough artificial turf portion has a turf length of 4 cm to 6 cm.

  The present invention resides in (4) the golf practice mat according to (1), wherein the artificial turf planted in the fairway artificial turf portion has a turf length of 0.5 cm to 1 cm.

  Further, according to the present invention, (5), a gap is formed between one side periphery of the rough artificial turf portion and the other side periphery of the fairway artificial turf portion, and the gap is exposed in the gap. The golf practice mat according to the above (1), in which a scale for recognizing the position of a golf ball is attached to the base part and the end part of the base part.

In the present invention, ( 6 ), the substrate portion is made of a synthetic rubber material, and the hardness of the synthetic rubber material is 80 degrees to 90 degrees (JIS-type A6 type hardness tester or JIS-K6301 type JA hardness meter. (Measured value) in the golf practice mat according to the above (1).

  In addition, as long as the objective of this invention is met, the structure which combined said (1) to (7) suitably is also employable.

According to the golf practice mat of the present invention, the board portion includes the rough artificial turf portion and the artificial turf portion for fairway whose turf length is shorter than the artificial turf portion for rough, and the artificial turf portion for rough and the fairway The artificial turf part has a wide part and a narrow part formed continuously with the wide part, and the wide part of the rough artificial turf part and the narrow part of the fairway artificial turf part are It is arranged correspondingly, the narrow portion of the artificial turf for rough and the wide portion of the artificial turf for fairway are arranged correspondingly, and the outer shape of the artificial turf for rough and the artificial turf for fairway is curved Because it is formed, there is no standard of directionality compared to the case where two simple turf grass areas are arranged as in the prior art, so it is difficult to take an address, and as a result, a high practice effect can be obtained. .
The area where the club head sinks into the turf increases as the ball moves forward. However, the wide and narrow portions are matched, so even a compact mat can be used.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a golf practice mat according to the present invention.
The golf practice mat A of this embodiment has a rubber substrate portion 1.
The outer shape of the substrate portion 1 is formed in a curved rectangle.
The substrate 1 is made of a synthetic rubber material, and the hardness of the synthetic rubber material is 80 degrees to 90 degrees (measured value with a JISK6253 type A type or JISK6301 type JA hardness meter). Yes.
When the hardness is within this range, as will be described later, even when the inclined support spacer 5 is fitted into the substrate portion 1 in order to incline the substrate portion 1 with respect to the horizontal plane, the substrate portion 1 is not bent. Can be maintained.

The board portion 1 is provided with a rough artificial turf portion 2 and a fairway artificial turf portion 3 having a turf length shorter than that of the rough artificial turf portion 2.
As the artificial turf portion 3 for fairway, artificial turf (for example, a polyester carpet) having a short hair and directivity can be used.
When a directional carpet is used, if a golf club is swung when a golf club is swung, a trace remains, so that a golf practitioner can correct his / her swing posture.
Any carpet can be used as long as it has a directionality.

The rough artificial turf portion 2 and the fairway artificial turf portion 3 have wide portions 2a and 3a and narrow portions 2b and 3b formed continuously with the wide portions 2a and 3a, respectively. .
The wide width portion 2a of the rough artificial turf portion 2 and the narrow width portion 3b of the fairway artificial turf portion 3 are arranged correspondingly, and the narrow width portion 2b of the rough artificial turf portion 2 and the fairway artificial turf portion. 3 wide portions 3a are arranged correspondingly.
More specifically, the one side periphery of the wide portion 2a of the artificial turf portion 2 for rough and the other side periphery of the narrow portion 3b of the artificial turf portion 3 for fairway are arranged adjacent to each other. One side periphery of the narrow portion 2b of the artificial turf portion 2 and the other side periphery of the wide portion 3a of the fairway artificial turf portion 3 are disposed adjacent to each other.
The rough artificial turf portion 2 and the fairway artificial turf portion 3 are formed in a curved shape.

Since the outer shape of each turf portion is formed in a curved shape in this way, there is no indication of directionality and it is difficult to obtain an address as compared with the conventional case where two rectangular turf regions are arranged side by side. be able to.
In addition, the perspective of the position of the golf ball is visually dull, and it is difficult to obtain an address.
This can also be said by forming the outer shape of the substrate portion 1 into a curved rectangle.

This will be described with reference to FIG. 2 assuming a golf driving range.
FIG. 2A shows a rectangular turf portion M1 formed on a conventional rectangular mat M. In this case, when one side of the turf portion M1 is set toward the pole P, the golf ball B An accurate flying ball direction F1 can be set, and the address is easily determined.
On the other hand, with the golf practice mat A of the present invention as shown in FIG. 2 (B), since the orientation cannot be recognized, it is difficult to set the flying ball direction in accordance with the accurate pole P.
As a result, an accurate address cannot be obtained, and conversely, the practice effect is improved.

By the way, it is preferable that the artificial turf (for example, made of nylon) planted in the rough artificial turf portion 2 has a turf length in the range of 4 cm to 6 cm.
If it is shorter than 4 cm, it is difficult to reproduce the golf ball in a sunken state, and if it is longer than 6 cm, the artificial turf tends to fall asleep.
The artificial turf planted in the fairway artificial turf portion 3 preferably has a turf length of 0.5 cm or more and less than 1 cm.
Within this range, the practice ball is on the artificial grass and is relatively easy to reproduce the fairway state.

Further, a gap is formed between one side periphery of the rough artificial turf portion 2 and the other side periphery of the fairway artificial turf portion 3 which are disposed adjacent to each other, and the substrate portion 1 exposed through the gap is formed. In addition, a linear scale 4A for ball position recognition is provided at regular intervals.
A triangular scale 4B is also attached to the end portion of the substrate portion 1 at regular intervals with the scale 4A.
The scale 4A and the scale 4B are provided around the rough artificial turf portion 2 and the fairway artificial turf portion 3, and the position of the golf ball can be easily recognized for each turf portion. it can.

FIG. 3 is a view of the golf practice mat A of FIG. 1 as viewed from the back side.
As shown in the figure, a rectangular plate-shaped concave portion 1 a is formed on the back surface side of the substrate portion 1.
A rectangular protrusion 1b is formed at the center of the recess 1a, and the protrusion 1b can prevent the recess 1a of the substrate portion 1 from being dented.
Further, the concave portion 1a and the protrusion 1b play a role of fitting an inclined support spacer 5 (5A, 5B) used for inclining the substrate portion 1 with respect to the horizontal plane.
As will be described later, the protrusion 1b is a portion that can be used in common when the inclined support spacer 5 is changed.

FIG. 4 shows a state in which the inclined support spacer 5A is fitted in the recess 1a. The inclined support spacer 5A is a block having a trapezoidal cross section in the lateral direction, and one surface thereof is in contact with the side wall on the short side of the recess 1a, and the surface opposite to this surface is in contact with and fixed to the protrusion 1b.
The inclined support spacer 5A is preferably made of soft plastic, and can be fitted into the recess 1a and the projection 1b made of a hard synthetic rubber material by being strongly pressed and slightly deformed.
Therefore, even when the entire golf practice mat A is moved with the inclined support spacer 5A attached, the position of the inclined support spacer 5A does not shift or come off.

Then, when the golf practice mat A with the inclined support spacers 5A fitted therein is placed on the ground G or floor such as concrete, it is as shown in FIG. 5 (cross-sectional view).
That is, as shown in the cross-section in the figure, the golf practice mat A is inclined in the flying direction F of the golf ball B and is lowered to the left, and the undulation of the lower left on the golf course can be reproduced. it can.

As described above, the substrate portion 1 is made of a synthetic rubber material, and since the hardness of the synthetic rubber material is 80 degrees to 90 degrees, the substrate section 1 has sufficient waist and does not bend as a whole.
On the other hand, when the inclination of the inclined support spacer 5A is reversed and fitted in the position of the one-dot broken line in FIG. 4, the golf practice mat A is inclined in the flying direction F of the golf ball B and goes up to the left. Can be reproduced.

Next, FIG. 6 shows a state in which the inclined support spacer 5B is fitted in the recess 1a.
The inclined support spacer 5B is a block having a trapezoidal cross section in the vertical direction, and one surface thereof is in contact with the side wall on the long side of the recess 1a, and the surface opposite to this surface is in contact with the protrusion 1b.
The inclined support spacer 5B can also be pushed in and fitted between the recess 1a and the protrusion 1b in the same manner as the above-described inclined support spacer 5A.

FIG. 7 is a cross-sectional view showing a case where the golf practice mat A in a state where the inclined support spacer 5B is fitted is placed on the ground G or a floor such as concrete.
In the state where the inclined support spacer 5B is fitted, the golf practice mat A is inclined upward in the direction perpendicular to the flying direction F of the golf ball B as shown in the cross section of the figure, The rising undulation can be reproduced.

On the other hand, when the inclination of the inclined support spacer 5B is reversed and fitted in the position of the one-dot broken line in FIG. 6, the golf practice mat A inclines in the direction perpendicular to the flying direction F of the golf ball B and falls forward. It is possible to reproduce the undulation before the course.
As can be seen from FIGS. 5 and 7, when the inclined support spacer 5 is disposed at any position, the protrusion 1 b can always support one side of the inclined support spacer 5, and the spacer 5 is changed. It can be used in common.

FIG. 8 illustrates a part of a cross section of the golf practice mat A.
Artificial turf 6 for forming artificial turf parts 2 and 3 is implanted in the substrate part 1, and the artificial turf 6 is not directly implanted in the substrate part 1, but via the sheet body 7. The structure is attached to the substrate unit 1.
Moreover, it is preferable that the artificial turf 6 processes the tape body and randomizes the leaf width.

The artificial turf 6 is implanted in a sheet body 7, and a flexible member 8 is attached to the back side of the sheet body 7 for preventing slipping and mitigating impact.
In addition, since the flexible member 8 is bonded and fixed so as to press down the root of the artificial turf 6, the artificial turf 6 is difficult to come off even if the leaves are long.
As a material of the flexible member 8, it is preferable to use a synthetic rubber such as urethane rubber, acrylic rubber, or silicon rubber.
The thickness of the flexible member 8 is preferably about 2 to 10 mm in order to prevent disconnection and to reduce impact.

  The sheet body 7 in which the artificial turf 6 is implanted from the front side and the flexible member 8 is adhered to the back side is fitted into the recess 1c formed in the substrate portion 1 as it is.

  As described above, the golf practice mat A of this embodiment cannot be punched out so as to actually take a turf like a natural course, but at least the flexible member 8 is interposed so that the club head hits it. In such a case, a feeling of biting occurs instantaneously, and it becomes close to natural rough.

FIG. 9 shows a state where the golf practice mat A is placed at the feet of the golf practitioner during practice.
In the figure, S indicated by a two-dot chain line is a standing area addressed by the golf practitioner.

9A, the fairway artificial turf portion 3 is located on the standing area S side, and the rough artificial turf portion 2 is located on the far side from the tunding area S.
A golf practitioner usually places and hits a golf ball on the grass in front.
At this time, the fairway artificial turf part 3 has the wide part 3a positioned forward (leftward in the figure) and the narrow part 3b positioned rearward.
Therefore, for example, when a golf ball placed on the narrow width portion 3b is hit, the golf club head is shot to hit a region located in front of the golf ball, and the area in which the club head sinks into the turf is increased. However, this wide part 3a can sufficiently cope with this.

  By the way, in the present invention, in order to make it compact, the narrow portion 3b of one turf portion and the wide portion 3a of the other turf portion correspond to each other and a region located in front of the golf ball, which is a portion requiring a large area Was set as the wide portion 3a, and a region located in front of the golf ball, which is a portion that does not require as large an area as the difference, was set as the narrow portion 3b.

In the practice mat A at the position shown in FIG. 9B, the rough artificial turf portion 2 is located on the standing area S side.
The practice mat A is in the state shown in FIG. 9B regardless of whether it is turned clockwise or counterclockwise from the state shown in FIG.
Even when the fairway artificial turf portion 3 is positioned on the standing area S side or the rough artificial turf portion 2 is positioned on the standing area S side, the left side is always wide and the right side is right. Becomes a narrow part.
That is, even if the manner of placing the practice mat A is changed, the left side is always the wide part and the right side is the narrow part, which is extremely useful for ordinary golf practitioners.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that other various modifications are possible without departing from the essence thereof.

For example, the balance of the areas of the wide and narrow portions of the artificial turf for rough and the artificial turf for fairway is not limited to that shown in the figure.
Further, the scale 4A and the scale 4B can be attached to portions other than those shown in the figure.
It is also possible to increase the frictional force with the place so as to prevent a lateral shift by providing a fine groove in the substrate part.
For left-handed people, each grass portion may be provided on the substrate portion so that the wide portion is on the right side and the narrow portion is on the left side.
Further, the size of the inclined support spacer can be freely selected as much as the inclination of the practice mat is possible regardless of the size of the concave portion of the substrate portion.
