Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a golf practice mat, and more particularly to a golf practice mat capable of obtaining a hit feeling resembling a rough state as much as possible.
[0002]
[Prior art]
The rough conditions on the course of nature are very varied and it is necessary for golf enthusiasts to practice according to their circumstances on a daily basis.
In general, in the course, there are many people who are not good at shots in the rough state where the grass 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.
[0003]
When a golf shot is practiced, it is often performed at a golf practice field or at home. Usually, 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, practice mats are currently being developed that assume rough and fairway conditions.
[0004]
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).
[0005]
Also, Japanese Utility Model Publication No. 63-201563 discloses a golf practice in which the matte foot of the follow-through side has a takeback longer than that of the sail, so that the club head falls down and returns. A stepped mat is shown (see Patent Document 2).
[0006]
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, although these golf practice mats are certainly made to resemble a natural rough, they simply have a grass leaf length similar to a rough.
In addition, the artificial turf leaves are uniform, which is very different from natural ones.
For this reason, the entangled state of the club head is different from that of natural turf, and it is impossible to reproduce a hit feeling close to a so-called natural rough state.
[0007]
On the other hand, for example, when a golfer goes out on the course and actually hits the ball on the turf with the club head, it is usually a shot to scrape the turf on the front side of the ball.
In other words, the club head is cut into the ground where the turf is planted.
Therefore, when an advanced player makes a shot using the above-mentioned golf practice mat, it is in a state of hitting the rear side of the ball placed on the mat, that is, the club head directly collides with the mat surface. A phenomenon occurs.
[0008]
However, unlike the natural surface, the mat ground cannot be cut off, so when the mat ground and the club head collide, the impact is directly transmitted to the grip and hurts the hand.
In this way, in the conventional golf practice mat, the artificial turf leaf looks like a rough state in appearance, but it realizes a hit feeling with a club head like an actual course. I can't.
[0009]
In other words, it was not satisfactory for expressing the natural rough state.
Thus, at present, no practice mat has yet been provided for obtaining a hit feeling in consideration of the turf form and the mat ground condition when shot.
[0010]

[Problems to be solved by the invention]
The present invention has been made in order to overcome such conventional problems, and it is an object of the present invention to provide a golf practice mat capable of obtaining a hit feeling resembling a rough state as much as possible.
[0012]
[Means for Solving the Problems]
Thus, as a result of earnest research on the background of such problems, the present inventor has focused on the width and material of artificial turf leaves and their planting sites, and adjusted their conditions so as to be unique. It has been found that a hit feeling can be obtained, and the present invention has been completed based on this finding.
[0013]
In other words, the present invention provides (1) a practice mat having a plurality of turf areas with artificial turf having different lengths on the mat, wherein artificial turf leaves of uniform width are provided in one turf area. The split film to be formed is scratched and finely cut along the stretching direction to form artificial turf leaves with a random width of 0.5 to 3 mm. The root of the artificial turf is on the front side of the sheet. The sheet body is embedded in a V-shape, and the sheet body exists on the back side of the golf practice mat fixed to the mat via a flexible member having a thickness of 2 to 10 mm .
[0014]
And (2), it exists in the mat | matte for golf practice of the said (1) description which has two turf areas.
[0016]
( 3 ) The golf practice mat according to the above (1) , wherein the artificial turf is formed of a polyolefin resin.
[0020]
And ( 4 ), it exists in the manufacturing method of the mat for golf practice characterized by having the following processes.
1. The process of weaving a split film into a sheet, bending it into a wave shape,
2. Cutting the bend at the tip of the split film to form leaves of artificial turf of uniform width made of split film ;
3. A step of scratching the artificial turf leaves of uniform width and finely cutting along the stretching direction to form artificial turf leaves having a random width of 0.5 to 3 mm;
4). Adhering a flexible member having a thickness of 2 to 10 mm to the back side of the sheet body;
5. A step of bonding and fixing the sheet body to the mat via the flexible member .
[0021]
As long as this invention meets this purpose, it is naturally possible to adopt a golf practice mat configuration in which two or more selected from the above (1) to ( 4 ) are combined.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the golf practice mat of the present invention will be described with reference to the drawings.
FIG. 1 is an external view showing a golf practice mat of the present invention, and FIG. 2 is a partial cross-sectional view thereof.
[0023]
The golf practice mat A of the present invention has a plurality of areas each including a mat 4 and an artificial turf 1 having different lengths thereon.
In this embodiment, a golf practice mat A having two areas, an area A having an artificial grass 1 having long leaves 11 and an area B having an artificial grass 1 having different short leaves 11 is shown. .
Further, the mat 4 has a portion where the artificial turf other than the region provided with the artificial turf 1 is not implanted, and a cutout hole is formed here.
[0024]
For example, the rectangular cutout hole H1 is used for a portion where a finger is hooked by hand when carrying it.
The circular cut-out hole H2 is used to fit a rubber pedestal (tee) from the back side and is used in a practice field.
The mat 4 is made of synthetic rubber, natural rubber or the like, and has an appropriate weight so as not to slip when shot.
Further, it is preferable to form means for preventing slippage, for example, an uneven groove on the back surface of the mat 4.
[0025]
The practice mat of the present invention includes the artificial turf 1, but the artificial turf 1 is structured to be implanted in the mat 4 via the sheet body 2 without being directly implanted in the mat 4. .
The length of the leaf 11 of the artificial grass 1 is preferably 4 to 6 cm.
The artificial turf 1 processes and processes the tape body to randomize the leaf width, which will be described later.
[0026]
By setting the length to such a length, it is possible to practice to make a shot with the golf ball B buried in the same manner as a rough golf course.
If the turf is shorter than 4 cm, the state in which the golf ball B is buried cannot be reproduced, and if the turf is longer than 6 cm, the artificial turf 1 tends to sleep and fall down.
[0027]
The artificial turf 1 is planted in a sheet body 2, and a flexible member 3 is attached to the back side of the sheet body 2 to prevent it from coming off and to reduce an impact.
As a material for the flexible member 3, it is preferable to use a synthetic rubber such as urethane rubber, acrylic rubber, or silicon rubber.
The thickness of the flexible member 3 is preferably about 2 to 10 mm in order to prevent disconnection and to reduce impact.
[0028]
The slip prevention effect and the impact relaxation effect will be described later.
The sheet body 2 in which the artificial turf 1 is implanted from the front side and the flexible member 3 is attached to the back side is bonded and fixed to the mat 4 as it is.
A recess 41 is formed in the mat 4, and the flexible member 3 is preferably fixed so as to be embedded in the recess 41.
[0029]
(Shock relaxation)
As described above, when a shot is made at a golf course, the more advanced players tend to scrape the soil behind the ball B, that is, the tendency to “take turf”.
FIG. 3 shows a state in which the ball B is buried in the artificial grass 1 of the long leaf 11 corresponding to the rough.
[0030]
FIG. 4 is a view showing a state in which the rear side of the ball B is scraped.
When the ball B on the artificial turf 1 of the practice mat A is shot in the practice field, the club head C tries to pass so as to scrape the mat 4 in the area behind the ball B after impact.
[0031]
At this time, since the club head strongly collides with the mat 4, the club head is hit and the impact is transmitted to the hand.
As described above, in the conventional practice mat A, not only the artificial turf 1 itself but also the state of the base provided with the artificial turf 1 (that is, the state of the artificial turf 1 planting place) has a great influence. Become.
[0032]
Therefore, in the present invention, the flexible member 3 is intentionally provided on the back side of the sheet body 2 in which the artificial turf 1 is implanted.
In other words, the flexible member 3 is attached to the back side of the sheet body 2 to enhance the cushioning property with the mat 4.
Therefore, the club head is prevented from strongly colliding with the hard mat 4 (for example, synthetic rubber), and the impact is softened and the hand is not damaged.
[0033]
However, the practice mat A of the present invention cannot be punched out so as to actually take a turf like a natural course, but at least when the club head hits the flexible member 3 because it is interposed. A feeling of biting occurs instantly, and it becomes closer to a natural rough than the conventional practice mat A.
[0034]
(Retaining)
If the leaf 11 of the artificial turf 1 is lengthened to resemble a rough state, for example, if the length exceeds 4 cm, which is a depth at which the ball B is hidden, the friction with the club head will increase and the turf will inevitably be hit. Easy to fall off.
In the present invention, since the flexible member 3 is bonded and fixed from the back side of the sheet body 2 so as to press down the root portion 12 of the artificial turf 1, the artificial turf 1 is not easily removed even if the leaves 11 are long.
Thus, in the practice mat of the present invention, the flexible member 3 has both functions of impact mitigating action and retaining prevention function.
[0035]
(Randomization of leaf width)
Natural turf has different leaf 11 widths one by one and they are not uniform.
The natural turf-likeness is a very important element that the individual widths of the leaves 11 are different.
[0036]
In the present invention, the width of the leaves 11 is positively formed so as to be unevenly distributed so as to resemble natural grass as much as possible.
As described above, in the artificial turf 1, as a method of randomly forming the width of the leaves 11, it is preferable to randomize the width of the leaves 11 using a tape body, for example, a split film T, as the artificial turf 1.
[0037]
The split film T is a tape-like film obtained by stretching a film in a uniaxial direction, and has a characteristic that a cut or a crack is generated in the stretching direction.
Utilizing this property, the split film T is finely cut along the stretching direction by applying an external force to the tape (for example, giving a scratching action in the stretching direction as will be described later).
The split film T is preferably a polyolefin resin, and more preferably a polypropylene resin.
[0038]
FIG. 5 is an enlarged view showing the state of the grass 11 in the present invention.
It can be understood that the split film T is divided in the length direction as a portion corresponding to the individual leaves 11 to generate the cracks P and have a random width.
In this way, the leaf width is random, and the shape is similar to the shape of a natural lawn.
Therefore, when practicing, the club head entanglement feels very similar to natural grass.
[0039]
(Implantation method)
In the golf practice mat A of the present invention, the artificial turf 1 is directly implanted in the sheet body 2 without being implanted in the mat 4 and is further attached to the mat 4 via the flexible member 3. Have various merits as described above.
An example of a method for manufacturing such a golf practice mat A will be described below.
[0040]
FIG. 6 is a block diagram showing the manufacturing process of the golf practice mat, and FIG. 7 is a schematic diagram showing the manufacturing process of the golf practice mat A.
Here, the case where the aforementioned split film is used as the artificial turf 1 will be described.
[0041]
1. (Planting process)
First, a large number of split films continuous on the sheet 2 are bent into a wave shape and implanted (A → B).
At this time, as can be seen in the figure, the split film is continuously bonded.
That is, each one corresponding to the leaf 11 of the artificial turf 1 (consisting of the leaf 11 and the root portion 12) is continuously integrated.
Although the case where a single split film is implanted in a wave shape is shown here, it goes without saying that the density of artificial turf increases when a plurality of split films are implanted simultaneously.
[0042]
2. (Cutting process)
Next, the bent portion at the tip of the split film is cut (B → C).
By cutting the tip with a knife or the like in this way, the split film becomes U-shaped at the root and becomes independent one by one, and forms the individual leaves 11 of the artificial grass 1. At this stage, since the split film has not yet been divided, the so-called leaf width remains uniform.
[0043]
3. (Backing process)
The flexible member 3 is attached to the back side of the sheet body 2 by adhesion (C → D).
A flexible member 3 such as urethane rubber is attached from the back side of the sheet body 2 using an adhesive or the like, and the root portion 12 (V-shaped portion) of the artificial turf 1 is pressed and fixed.
A part of the base of the split film (that is, the root portion 12 of the artificial turf 1) is exposed on the back side of the sheet body 2, but since the sheet is pressed down by the flexible member 3 and bonded and fixed, There is no omission.
[0044]
4). (Division process)
In the previous step, the leaves 11 of the artificial turf 1 are formed by the split film, but the width of the leaves 11 is still equal to the same width.
In order to bring this closer to natural turf, the split film is divided using the comb tool of the artificial turf 1 of the split film and divided in the direction of stretching (D → E).
By receiving the scratching action in this way, the split film is cracked at an arbitrary position and individually separated to form the artificial turf 1 having a random leaf 11 width.
[0045]
5. (Attaching process with mat)
The sheet body 2 in a state where the artificial turf 1 is implanted is attached to the mat 4. Usually, the sheet body 2 is fixed to the mat body using an adhesive (E → F).
The manufacturing process of the golf practice mat A is thus completed.
In addition, in the said manufacturing process, if it has passed through the cutting process, the adoption process of a division | segmentation process is free.
[0046]
FIG. 8 is a block diagram showing another manufacturing process of the golf practice mat, in which (A) shows the case where the dividing process is after the cutting process, and (B) shows that the dividing process is attached to the mat. This is the case after the process.
Also, in the planting process, as shown in FIG. 9, when the split film is alternately bent and planted in a wave shape [see (A)], the cutting process results in twice as many grasses (see (B)). ].
[0047]
[Other Embodiments]
As described above, in the golf practice mat of the present invention, the flexible member has a function of preventing slipping and impact mitigation.
However, it is sufficiently useful because at least the width of the artificial grass leaves is randomly formed.
[0048]
FIG. 9 is a schematic view showing a cross section of a golf practice mat in which the mat 4 is bonded and fixed directly to the back side of the sheet body 2 with an adhesive R without providing a flexible member.
Since the leaf width of the artificial turf is random, the club head entanglement feels close to natural turf when practicing.
[0049]
Although the present invention has been described above, the present invention is not limited to the embodiments, and it goes without saying that various other modifications are possible without departing from the essence thereof.
[0050]
For example, an anti-slip function can be provided below the mat 4 of the golf practice mat A, and other functions can naturally be provided.
It is also possible to provide a hole for attaching a string that connects the ball B for practice. The mat 4 provided with the artificial turf 1 has a uniform thickness, but the area of the artificial turf 1 with the long leaves 11 is the lower stage, and the area of the artificial turf 1 with the short leaves 11 is the upper stage. In addition, it is possible to have four mats with different heights for each region.
In addition, in the plurality of turf areas, the area occupied by the areas can be appropriately set differently.
[0051]
【The invention's effect】
When shot with the golf practice mat of the present invention, it is possible to obtain a hit feeling and a turf feel similar to a natural rough state as much as possible, and even a senior can obtain a practice effect sufficiently. .
Further, unlike a golf practice mat in which a long artificial turf is planted, the artificial turf is difficult to fall out and has excellent durability.
