Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the improvement of artificial turf laid on balconies, bathrooms, etc.

(Conventional technology) Conventional artificial turf has two types: one in which flexible nylon fibers are planted on the top surface of a polyethylene sheet, and the other in which the turf part is integrally molded (injection molding) using the same polyethylene material as the drainage base. It has been known.

(Problems to be solved by the invention) However, conventional artificial turf has the following problems.

In other words, the former type of artificial turf, in which flexible nylon fibers are planted on the top surface of a polyethylene sheet, has a texture similar to that of grass, but because the sheet itself does not have a horizontal drainage function, it has poor drainage. There was a problem with that.

In addition, the latter type of artificial turf equipped with a drainage base has a lateral drainage function, which improves drainage, but the texture of the turf is extremely poor, and moreover, the back surface of the substrate has a certain spacing. Since it had a structure in which the pillars were formed protruding from the top, there were problems in that it was easy to warp during or after molding, and it also lacked strength.

Therefore, the present invention aims to solve these problems and provide artificial turf that is soft to the touch, has good drainage, has excellent strength, and does not cause warping of the substrate.

(Means for Solving the Problem) In the present invention, as a means for achieving the above-mentioned object, an artificial turf in which flexible synthetic resin fibers are planted on a sheet having a large number of water holes, and a It consists of a combination with a drainage base laminated on the back side, and as the drainage base, each block defined by vertical and horizontal lines drawn in a grid pattern on the base plate is recessed every other vertically and horizontally to form a leg plate. forming a part, and
A side wall connecting the leg plate and the base plate is provided with a communication hole for drainage.

(Function) As mentioned above, in the artificial turf of the present invention, the drainage base is laminated on the back side of the artificial turf, which is made of a sheet with many water holes and flexible synthetic resin fibers planted on it.
Vertical water flow function in artificial turf sheets,
Due to the horizontal drainage function in the drainage base,
The water drainage efficiency is extremely high, and the flexible synthetic resin fibers provide a good texture.

Further, as the drainage base, each block defined by vertical and horizontal imaginary lines drawn in a grid pattern on the base plate is recessed every other block vertically and horizontally to form a leg plate portion, and the leg plate portion and By having a communication hole for drainage in the side wall that connects the base plate, it not only has a horizontal drainage function, but also has excellent strength, and the connection between the base plate and the leg plate. Since the areas are approximately the same, warping is less likely to occur during molding and thereafter, and since the lattice-like arrangement serves as a guide line, cutting work for size matching can be easily performed.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

First, the configuration of the embodiment will be explained.

The artificial turf A of this embodiment mainly includes an artificial turf 1 and a drainage base 2, as shown in FIGS. 1 to 7.

The artificial turf 1 is made by planting flexible synthetic resin fibers 12 on a sheet 11 having a large number of water holes 10. In this embodiment, the sheet 11 is made of nylon mixed with glass fiber. In addition, nylon fibers are used as the flexible synthetic resin fibers 12 that make up the grass.

The drainage base 2 is a base for providing a horizontal drainage function on the back surface of the artificial turf 1, and is a base that has vertical and horizontal lines m and n drawn in a grid pattern on the base plate 20. The leg plate portions 21 are formed by recessing every other block vertically and horizontally, and the leg plate portions 21
and each side wall portion 22 connecting between the substrate portion 20 and the substrate portion 20.
A communication hole 23 for drainage is provided in the drain.
In this embodiment, a circular hole 25 is provided in a portion other than the recessed portion 24, and one circular hole 25 is provided in each of the vertical and horizontal directions.
By forming the leg plate part 21 at a position slightly floating above the ground surface, it is possible to prevent water from accumulating by the thickness of the leg plate part 21.

In addition, in the example, the interval between vertical and horizontal virtual lines m and n drawn in a grid pattern is 10 mm, and the total length and width are 50 mm x 50 mm.
It is formed into a block of mm, and a large number of engagement pieces 26 for connection are protruded from two side surfaces that intersect at right angles. This engagement piece 26 fits from below into a recess 27 formed between the recesses 24 on the back side of the drainage base 2, and
Protrusions 28, 2 that fit into communication holes 23, 23 formed in the left and right side walls 22, 22, respectively.
8, and has a structure in which a slit 29 is formed at the center of the tip of the engaging piece 26 to facilitate fitting of both the projections 28, 28. There is.

Further, on the outer peripheral edge of the upper surface of the drainage base 2, a frame portion 30 that can surround the end surface of the sheet 11 of the artificial turf 1 is provided.
is formed protrudingly.

In addition, as the material for the drainage base 2, in this embodiment, polypropylene resin with rubber powder added is used to give the drainage base 2 appropriate cushioning properties, and also to improve the dimensions, which are the drawbacks of polypropylene. This compensates for the lack of accuracy.

By forming draft angles on the side surfaces of each member, the structure is such that it can be integrally molded using upper and lower split molds.

Then, the back surface of the sheet 11 of the artificial turf 1 is adhered to the upper surface of the substrate section 20 of the drainage base 2, thereby integrating the two.

Next, the operation of the embodiment will be explained.

Since this embodiment has the above-mentioned configuration, a plurality of pieces of artificial turf A are connected and used depending on the size of the area where it is to be laid.

When connecting the two, the engagement piece 26
With the protruding side facing down, insert the engaging piece 2 from above.
6 are overlapped from above, and in this state, when the side edges are pressed downward, both the left and right protrusions 28, 28 of each engagement piece 26 are made flexible by the slit 29. Therefore, each engagement piece 26 is fitted into the communication holes 23, 23 of the left and right side walls 22, 22 in the recess 27, and is maintained in the engaged state within each recess 27.

In addition, the water that flowed onto the top surface of artificial turf A is
into the recess 24 through the large number of water holes 10 provided in the sheet 11, or through the water holes 1 in the sheet 11.
0 and into the recess 27 through the circular hole 25 of the substrate portion 20, and the respective side wall portions 22
The liquid flows laterally through the communication hole 23 opened in , and is discharged to the outside.

As explained above, in the case of the artificial turf A of this embodiment, as described above, the back surface of the artificial turf 1 is made by planting flexible synthetic resin fibers 12 on the sheet 11 provided with a large number of water holes 10. By laminating the drainage base 2 on the artificial turf 1, the sheet 11 of the artificial turf 1 has a vertical water flow function and the drainage base 2 has a horizontal drainage function, resulting in extremely high drainage efficiency and flexibility. The synthetic resin fibers 12 provide a good texture.

Further, as the drainage base 2, each block defined by vertical and horizontal lines m and n drawn in a grid pattern on the base plate part 20 is recessed every other block vertically and horizontally to form a leg plate part 21, and , the leg plate portion 21 and the base plate portion 2
The side wall 22 that connects the base plate 20 and the base plate 20 has a communication hole 23 for drainage, which not only has a lateral drainage function but also has excellent strength. Since the areas of the portions 21 are approximately the same, warping is less likely to occur during molding and thereafter, and since the lattice-like arrangement serves as a guide line, cutting work for size adjustment can be easily performed.

Further, in the embodiment, by providing the engaging piece 26, it becomes possible to connect a plurality of artificial grasses A and use them in any desired area.

Furthermore, in this embodiment, the size of each block is as small as 10 mm square, so that the strength of the drainage base 2 is hardly affected no matter where it is cut.

In addition, in the embodiment, by forming every other leg plate 21 vertically and horizontally at a position slightly raised above the ground surface, it is possible to prevent water from accumulating due to the thickness of the leg plate 21, and drain water smoothly. It will be held in

In addition, in the embodiment, by using polypropylene with rubber powder added as the material for the drainage base 2, the drainage base 2 can be provided with a cushion function, and the molding accuracy of polypropylene can be improved. You will be able to do this.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. include.

For example, in the embodiment, polypropylene with rubber powder added was used as the material for the drainage base 2, but the material is not limited to this, and polypropylene, polyethylene, vinyl chloride, etc. may be used alone.

Moreover, the material of the artificial grass 1 is also arbitrary.

(Effects of the invention) As explained in detail above, the artificial turf of the invention has a drainage base on the back side of the artificial turf, which is made by planting flexible synthetic resin fibers on a sheet with many water holes. By laminating the artificial turf sheets, the water drainage function is extremely high due to the vertical water flow function of the artificial turf sheet and the horizontal drainage function of the drainage base.
Moreover, the soft synthetic resin fibers provide a good texture.

Further, as the drainage base, each block defined by vertical and horizontal lines drawn in a grid pattern on the base plate is recessed every other block vertically and horizontally to form a leg plate,
In addition, by having a communication hole for drainage in the side wall connecting between the leg plate part and the base plate part, it not only has a horizontal drainage function, but also has a horizontal drainage function.
In addition to having excellent strength, the areas of the base plate and the leg plate are approximately the same, so warping is less likely to occur during molding and afterward, and the grid-like arrangement serves as a guide wire, making it easy to cut for dimension matching. The effect is that the work can be done easily.
