Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mat for gateball using artificial turf.

[Conventional technology]

The conventional artificial turf for gateball is made of cut fibers made of synthetic fibers with a cut length of about 6 mm to 7 mm, densely planted on one side of the base fabric, and bonded to the back side of the base fabric with an adhesive such as rubber. Therefore, the mats used for playing on conventional artificial turf do not have the so-called stiffness, which has fundamental drawbacks such as the fibers becoming loose and slipping during sparks. It has the disadvantage that it cannot be played immediately because it remains in the pine fibers for a long time.

[Problem that the invention attempts to solve]

The present invention was developed in view of the above-mentioned drawbacks of conventional gateball mats using artificial turf.(a) The ball rolls naturally.

(b) The ball should not slip and roll easily when sparking.

(c) Unlike conventional artificial turf, it does not contain much water and has good drainage, so it can be played smoothly even after rain.

(d) The gateball mat is resistant to so-called fatigue.

(e) Contrary to conventional mats, there is no directionality for the rolling of the ball.

As a result of repeated studies by the inventor of various prototypes, the inventor has completed a gateball mat using the artificial turf of the present invention.

[Means to solve the problem]

This invention uses continuous yarn of synthetic fiber or slit yarn made of synthetic resin with a pile length of 3 mm to 7 mm.
Thin piles and loops of monofilament coated with plastic synthetic resin are alternately knitted into a base fabric in rows, and an adhesive is applied to the back side of the base fabric. The present invention provides a gateball mat.

The continuous yarn of pile-like synthetic fibers or the slit yarn made of pile-like synthetic resin used in the present invention may be of any type or thickness, but the thickness of the slit yarn is preferably 500 to 5000 dale, In addition, continuous threads of pile-like synthetic fibers are made of polypropylene fibers, and slit yarns made of pile-like synthetic resins are made of polypropylene resin.
Furthermore, as the loop-shaped synthetic fiber monofilament coated with a thermoplastic synthetic resin, it is preferable to use a monofilament in which a polyester monofilament is coated with a vinyl chloride resin.

The length of the above pile is 3mm to 7mm, preferably 5mm
~6mm. Pile length less than 3mm or 7mm
If it exceeds the above, the gateball mat of the present invention as described below will not be effective.
It's inappropriate.

The thickness of the synthetic fiber monofilament coated with thermoplastic synthetic resin formed into a loop has an outer diameter of 0.4
The outer diameter is 1 mm to 2 mm, preferably 1 mm to 2 mm, and the loop length is 0.5 mm to 4 mm, depending on the pile length of the continuous yarn of piled synthetic fibers. As the adhesive to be bonded to the back side of the mat, synthetic resin, natural rubber, or synthetic rubber adhesives are used, but preferably
SBR coating material is used to knit continuous threads or slit yarns of pile-like synthetic fibers or monofilament of synthetic fibers formed into loops into the base fabric, which is then coated and bonded with SBR coating material. Or the loop portion is firmly adhered to the base fabric.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 shows a partial perspective view of an embodiment of a gateball mat using artificial turf of the present invention, and Fig. 2 shows a partial perspective view of a conventional gateball mat using cut fibers. be. 1st
As shown in the figure, the pile fibers of the gateball mat 1 are slit yarns made of polypropylene resin with a pile length of 6 mm, and the loop-shaped monofilament of synthetic fibers coated with synthetic resin is polyester. It is preferable to use synthetic fibers coated with vinyl chloride resin, and the ratio of synthetic fibers to vinyl chloride resin to be about 1:3. The size of one mat for gateball of this invention is, for example, if the width is 2.5 m, the length is 25 m, and the width is 20 m according to the standard for gate ball, there are 3 mats.
In the case of a width of 15 m, it is suitable to use six sheets, but of course the use is not limited to this, and various sizes can be manufactured.

Figure 2 shows a conventional gateball mat in which cut fibers 4 are densely implanted, which has the drawbacks mentioned above.
This figure is shown for comparison with the present invention.

Various colors can be used for gateball mats, but usually the playing part is green, and the regulating part, the so-called picture frame part, is yellow, whether it is a pile-like continuous yarn of synthetic fibers or a pile-like slit yarn.

According to the standards, the playing part of a gateball mat is a green pine measuring 25m long and 20m wide, or 20m long and 15m wide, with a height of 4mm, and therefore a loop height of 4mm, and a 1m wide yellow pine. However, in this invention, the height of the pile or loop of the playing mat is 4 mm.
If the pile length in the restricted area is at least 3.5
It is preferable to set it to mm.

If the difference between the playing part and the regulating part is 0.5mm,
Because the ball rolls down from the playing area toward the regulation area, it is much clearer to indicate whether the ball is in or out than when traditional strings or tape demarcate the playing area and the regulation area. (OUT) can be determined, which has the advantage of completely preventing troubles with the rules.

[Effects of this invention]

The effects of the present invention are summarized as follows.

(a) The ball rolls well and is similar to naturally reinforced soil.

(b) Contrary to conventional artificial turf, where the ball slides when sparking, this invention uses synthetic fiber monofilament coated with thermoplastic synthetic resin formed in a loop shape in every other row, so the spark does not occur. Sometimes the ball doesn't slide.

(c) Unlike conventional artificial turf, it does not contain water and has good drainage, so you can play immediately even after rain.

(d) Since it uses a continuous yarn of pile-shaped synthetic fibers, a slit yarn made of pile-shaped synthetic resin, or a monofilament of synthetic fiber coated with thermoplastic synthetic resin formed into a loop, it is possible to use mats for gateball. It is extremely strong against so-called fatigue.

(E) By making the height of the regulating part of the gateball mat at least 0.5 mm lower than the height of the playing part, when the ball comes to the boundary, it will roll down to the regulating part, so it will not be possible to use conventional strings or tape. Compared to determining boundaries, determining whether the ball is in or out is more accurate, and disputes over rules can be completely prevented.
