Description

[Detailed description of the invention] [Technical field] This invention is a method for applying artificial grass such as gateball, baseball, tennis, soccer, etc. to the surface of artificial turf laid in stadiums, etc.
This invention relates to display tape for drawing lines for various competitions such as volleyball, or for attaching competition indications.

[Conventional technology]

Recently, artificial turf has been increasingly installed in indoor or outdoor stadiums and used as courts for games such as gateball, tennis, and volleyball, or as grounds for various sports such as baseball and soccer. Conventionally, methods for drawing competition lines on artificial turf include embedding white artificial turf or applying white paint. However, with white artificial turf embedded, it is impossible to remove or change the position of the line.
If the line is coated with paint, the paint must be erased when removing or changing the position of the line, making the work complicated. Furthermore, when erasing the paint, the paint may not be completely erased, which may impair the aesthetic appearance of the artificial turf.

[Problem that the invention attempts to solve]

Therefore, in order to eliminate the above-mentioned disadvantages, display tape made of fibers or resin is placed on the artificial grass.
It is used as a competition line. However, with this method, if a player or the like touches the display tape, the line position can easily shift. Another method is to use an adhesive to attach the display tape to the artificial turf, but in this case, when the line is removed or changed, the adhesive remains on the surface of the artificial turf. and cause dirt.

Furthermore, on the back of the display tape, there is a hook-shaped tip.
It is also possible to fix the display tape by providing a plurality of mushroom-shaped or umbrella-shaped engaging protrusions and engaging the engaging protrusions with the artificial grass pile. In this type of display tape, it is preferable that the tip of the engagement protrusion has a curved shape such as a spherical surface so that the tip of the engagement protrusion can easily and reliably engage with the pile when installed on artificial turf. However, manufacturing each engagement protrusion with a spherical or curved tip is extremely complicated, and the process of implanting a large number of these engagement protrusions into the display tape is also extremely complicated. .

The present invention was made to solve the above-mentioned conventional problems, and it is possible to easily manufacture a large number of engagement protrusions that engage with the surface of artificial turf. The purpose is to provide a display tape for artificial turf that can be fixed.

[Specific measures to solve the problem]

The present invention is an indication tape for artificial turf that consists of a tape body that is installed on the surface of artificial turf and a plurality of engagement protrusions that protrude from the tape body and are latched to the surface piles of the artificial turf. The tape body is formed by weaving the tape body, and the engagement protrusion is formed by protruding a part of the synthetic resin fiber from the tape body, and a hemisphere is formed at the tip of the engagement protrusion by heat treatment. It is characterized by an integrally formed head having a diameter larger than the thickness of the synthetic resin fiber.

[Effect]

This display tape has multiple engaging protrusions, and the hemispherical protrusion, which has a larger diameter than the synthetic resin fibers provided at the tip of the engaging protrusions, is fixed by catching on the artificial turf pile. be done. In other words, since the surface of the head of the engaging protrusion is spherical, when the display tape is installed on artificial grass, the engaging protrusion easily engages with the surface pile. The neck of the shaped protrusion is reliably caught on the pile of artificial grass, and the display tape is installed without being easily displaced. In addition, the tape body is formed by knitting synthetic resin fibers, and the engaging protrusions are formed by protruding a portion of the synthetic resin fibers from the tape body, making it unnecessary to implant the engaging protrusions. . Furthermore, since the head at the tip of the engagement protrusion is formed by heat-treating synthetic resin fibers, the work of molding this head is easy.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings of FIGS. 1 to 4.

FIG. 1 is an enlarged side view showing a surface tape for artificial turf and artificial turf according to an embodiment of the present invention, FIG. 3 and 4 are side views showing a winding tool for display tape for artificial turf.

In FIG. 1, reference numeral 1 indicates artificial turf. This artificial turf 1 is laid indoors or outdoors and is used as a court or ground for various games such as gateball. In the artificial turf 1, surface piles 1b made of fibers such as polyvinylidene chloride, polypropylene, nylon, etc. are planted on a base material 1a made of polyester, polypropylene, etc.

Reference numeral 2 is a display tape for displaying competition lines on the artificial turf. The tape main body 2a of the display tape 2 is made of synthetic resin fibers such as nylon, polypropylene, and polyester. On the back side of this tape body 2a,
A plurality of engagement protrusions 3 that are engaged with the surface pile 1b of the artificial turf 1 are provided in an array. This engaging protrusion 3 is also made of synthetic resin fibers such as nylon, polypropylene, and polyester. As shown in FIG. 1, the engaging protrusion 3 has a hemispherical head 3a. This hemispherical head 3a is
The surface is spherical and has a diameter larger than the thickness of the engaging protrusion 3.

The engagement protrusion 3 is molded integrally with the tape body 2a. That is, the tape body 2a is made of nylon,
The engagement protrusion 3 is formed by knitting synthetic resin fibers such as polypropylene or polyester, and the engaging protrusion 3 is formed by making a large number of parts of the knitted synthetic resin fiber protrude from the back side of the tape body 2a.

As shown in FIG. 1, the tip of the engagement protrusion 3 is melted by heat to form a hemispherical head 3a.
Therefore, a step is formed at the boundary between the fiber portion of the engagement protrusion 3 and the head 3a (the neck of the head 3a).

Since the head 3a is formed by heat treatment, any synthetic resin fiber that can be melted by heat can be used as the material for the engagement protrusion 3, but the most preferred synthetic resin fiber is polypropylene.
Polypropylene is stronger than other resin fibers, and when installing the display tape 2 on artificial turf,
The engaging protrusion 3 is difficult to bend and easily gets into the surface pile 1b. In addition, when polypropylene synthetic resin fibers are used, they are strong and the cut surface cuts neatly at right angles when cut, and their melting point is low, so during the subsequent heat treatment, all the engaging protrusions are removed. 3, the molten state becomes uniform, and hemispherical engagement protrusions 3a with a uniform shape can be formed.

If the tape main body 2a manufactured as described above is made elongated, competition lines can be displayed on the surface of the artificial turf. Furthermore, if the tape main body 2a is shaped to match numbers or competition displays, it can be used for competition displays other than lines.

As shown in FIG. 2, the display tape 2 is laid by placing the tape body 2a on the surface of the artificial turf 1 and applying pressure. At this time, the head 3 of the engagement protrusion 3 provided on the back surface of the tape body 2a
Since the surface of a is spherical, and polypropylene is strong, the engaging protrusion 3 can easily enter the inside of the surface pile 1b.
In addition, the diameter of the head 3a is larger than the thickness of the fibers of the engaging protrusion 3, and a step is formed at the neck of the head 3a, so that the head 3a is securely attached to the curled surface pile 1b. The display tape 2 is fixedly installed by being locked or entangled with the display tape 2 so that it does not easily shift. Furthermore, the display tape 2 can be easily removed by peeling off the tape body 2a and pulling out the engaging protrusion 3 from the surface pile 1b.

FIG. 3 shows a winding tool 4 for the display tape 2. As shown in FIG. Attach one end of the display tape 2 to the roll in the winder 4 with adhesive tape or the like, and then attach it to the handle 4a.
By turning the display tape 2, the display tape 2 can be stored in the case. Winding tool 4 shown in FIG.
has a pressure roller 5 at its lower end. When pulling out the display tape 2 from inside the winding tool 4 and installing it on the surface of the artificial turf 1, if at the same time pressure is applied by the pressure roller 5, the engaging protrusion 3 provided on the display tape 2 can be moved to the surface pile 1b. You can make sure it gets pushed inside.

[Effect of idea]

As described above, according to the present invention, a hemispherical head with a diameter larger than the thickness of the fibers is provided at the tip of the engaging projection protruding from the tape body, so that the tape body can be installed on artificial turf. Sometimes, this head can easily get inside the artificial turf pile. Moreover, once inserted, the neck of the hemispherical head reliably engages with the pile, and the display tape is installed on the surface of the artificial turf without shifting.

In addition, the tape body is formed by weaving synthetic resin fibers, and the engaging protrusions are formed by protruding some of the synthetic resin fibers, so there is no need to implant a large number of engaging protrusions into the tape body. be. Furthermore, since the tip of the engaging protrusion is heat-treated to form a head with a curved surface, the shaping operation of the head is easy.
