Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an artificial turf mat used in golf courses, golf driving ranges, two schoolyards, gardens, etc.

(Prior Art) Conventionally, for example, artificial turf mats used at golf courses, etc., are general artificial turf mats in which a large number of flanges are planted on the top surface of the base. Sand was filled in between so that the upper end of the flange protruded from the top surface.

Therefore, the conventional artificial turf mat has the advantage that the tee can be erected by the sand, and the flange is held in place by the sand, thereby preventing the flange from tipping.

(Problems to be Solved by the Invention) However, conventional artificial turf mats have the following problems.

Because Frente is planted at regular small intervals horizontally and vertically,
It is difficult for sand to enter between the fins (and sand filling becomes insufficient).

Since there is no drainage means on the base, water puddles on the mat when it rains.

Due to the inclusion of clayey soil, the filled sand gradually hardens.

In order to obtain a stance feeling similar to natural grass, it is necessary to make the sand layer thicker, but conventionally, if the sand layer is made thicker, the protruding length of the Frente becomes longer than necessary to correspond to the thickness of the sand layer. As a result, there are problems with durability such as the Frente falling over or bending, and the eyes of the Frente are disturbed, resulting in an unsightly appearance.

In cases where the club hits the sand when hitting the ball, so-called duffling, and a force is applied to the Frente in the direction of the pull, the Frente may be pulled off the base.

The present invention was made in view of the above-mentioned conventional problems, and it is easy to fill with sand, and it does not make the protruding length of the Frente longer than necessary. It is possible to obtain a sand layer thick enough to obtain a similar feeling of stance, has strong resistance to the removal of Frente, has good drainage of rainwater, and is easy to manufacture. The first objective is to provide mats, and the second objective is to provide artificial turf mats that can prevent the filling sand from solidifying.In addition, the second objective is to provide artificial turf mats that can prevent the filling sand from scattering or spilling. The purpose is 3.

(Means for Solving the Problem) In order to achieve the above-mentioned first object, in the artificial turf mat according to claim 1 of the present invention, a large number of protrusions are integrally molded and protrude in parallel on the upper surface of the base of the mat member. and a large number of permeable holes are formed through the base, and on the upper surface of the ridge, a large number of Frentes are planted continuously in the length direction of the ridge,
The Frente has a structure in which the root portions embedded in the protrusions are connected in a continuous direction with knitting threads, and the inside of the mat member is filled with sand-like material so that the upper end of the Frente protrudes from the upper surface. did.

In order to achieve the second object, in the artificial turf mat according to claim 2, a water permeable elastic layer having water permeability and elasticity is interposed between the base of the mat member and the filling sand. The configuration is as follows.

In addition, in order to achieve the third object, the artificial turf mat according to claim 3 has a structure in which the filling sand-like material is solidified with a coagulant, and the artificial turf mat according to claim 4, in which the mat member is It has a structure with standing walls all around the base.

(Function) In the artificial turf mat according to claim 1 of the present invention, the Frente is continuously planted in the longitudinal direction of the ridges, so that the Frente is arranged in a striped manner, and there is a constant width between the gaps. Since the spacing is maintained, filling with sand is facilitated.

Also, the thickness of the sand layer is determined by the depth to the top of the base, and the length of the Frente protrusion is sufficient to be the length to the top of the ridge, so it should be shortened by the height of the ridge. This allows you to obtain a stance similar to that of natural grass while preventing the Frente from falling over or bending.

Furthermore, depending on the height of the protrusions, the planting depth of the Frente can be set deep, and since the roots of the Frente are connected with knitting threads, strong resistance against removal is obtained.

In addition, rainwater permeates into the sand-like material and then drains underground through the permeable holes formed in the base, so that no water accumulates on the top surface of the mat.

In the artificial turf mat according to claim 2 of the present invention, when a load is applied to the upper surface of the filled sand, the water-permeable elastic layer is compressed in response to this load, causing the filled sand to sink downward. , sand filled with elasticity of water-permeable elastic layer, when the load is released,
Since the shaped body is pushed back upward, the solidification of the filled sandy body is prevented by the vertical movement of the filled sandy body itself.

In the artificial turf mat according to the third aspect of the present invention, since the sand-like material is solidified with a coagulant, the sand-like material is not scattered more than necessary (and a stable stance can be obtained).

In the artificial turf mat according to claim 4 of the present invention, the filled sand-like material is held by the vertical wall, so that it does not spill out from the mat member.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the first embodiment will be explained.

Fig. 1 is a plan view showing an artificial turf mat A according to the first embodiment of the present invention, Fig. 2 is a sectional view taken along Fig. 1 1-I, and Fig. 3 is Fig. 1
(2) It is a sectional view, and 1 in the figure indicates a mat member.

The mat member l has a standing wall 11 protruding from the entire periphery of a base 10, and a large number of protrusions 1 at a constant pitch on the upper surface of the base 10.
2 protrude in parallel, and a groove 13 for flange planting is formed on the upper surface of the protrusion 12 over the entire length, and between the protrusion ridges 12 and 12 and between the protrusion 12 and the standing wall 11. In between,
A water permeable hole 14 for drainage is formed through the base 10.

Moreover, this mat member 1 is made of foamed vinyl chloride resin, and the base 10, the vertical walls 11, and the protrusions 12 are integrally molded. In addition, in the embodiment, the planar outline of the mat member 1 is as follows:
It is formed into a rectangle with a length of 300mm and a width of 600mm, the thickness of the base 10 is 10mm, the height of the standing wall 11 is 67mm,
Further, the protrusions 12 are formed to have a width of approximately 10 mm, a height of 30 mm, and a pitch of 20 mm.

In addition, the water permeable holes 14 are formed in an oval shape with a total length of 50 mm, are arranged at intervals of 20 mm in the longitudinal direction of the protrusion 12, and are adjacent to each other with the protrusion 12 in between.
14 are arranged in a staggered manner.

A large number of flexes 2 are continuously planted on the upper surface of each ridge 12 of the mat member 1 in the length direction of the ridge 12, and the flexes 2 that are continuous on the ridge 12 are A root part 20 planted on the base part 2 is knitted with a knitting yarn 3 made of vinyl chloride and connected in a continuous direction. Incidentally, the flex 2 is made by applying vinyl chloride paste as an adhesive to the root portion 2 using a spatula or the like, and applying this to the groove 13 formed on the upper surface of the protrusion 12.
In this case, it is implanted by inserting it into the
Since the mat member 1, the knitting yarn 3, and the adhesive are all made of vinyl chloride, strong adhesive strength can be obtained. Also, Fletsk 2
is made of nylon 66, colored green, and has a total length of 5
0n+m, root part 20 is 20mm, protrusion length is 30mn
It is +.

Furthermore, inside the mat member 1, a sand-like material 4 is placed on the vertical wall 1.
As a result, the upper end 21 of the flex 2 is approximately 3.3 m from the upper surface 40 of the sand 4.
It protrudes with a length of n+m. Incidentally, silica sand colored green to match the color of the flange 2 is used for the sand-like body 4, and for the coloring, for example, "Product name: Vermicron Top AU413" manufactured by B-O Chemical Co., Ltd. A coating liquid containing an epoxy-based green pigment called "Light Green" and a hardening agent mixed in a ratio of 4:1 is used.
silica sand is colored green by mixing and stirring 500 to 600 g of silica sand No. 4. Although this will harden if left as is, it is desirable to heat it while stirring in order to prevent the silica sand from becoming enlarged due to adhesion between the silica sand particles.

Furthermore, the silica sand constituting the sand-like body 4 filled inside the mat member 1 is solidified by a coagulant, and this assimilation is performed by spreading the coagulant over the silica sand. As the coagulant at this time, for example, acrylic emulsion manufactured by Dainippon Ink and Chemicals Co., Ltd. [Product name: RYUDYE-WF I
The water permeability of the sand is maintained.

Next, FIG. 4 shows an example of construction in which the artificial turf mat A of this embodiment is laid on the teeing ground of a golf course.

In this construction example, a water-permeable block 6 is laid on the ground 5 of the teeing ground, and a plurality of artificial turf mats A are spread on the water-permeable block 6 without gaps. The water-permeable block 6 is made of, for example, epoxy resin mixed with pigment and a curing agent mixed therein.
It is formed by mixing and stirring with No. 1 silica sand, filling it into a mold such as a box, and allowing it to harden naturally, or by heating and hardening rapidly. If a wire mesh is buried as a core material in this water-permeable block 6, a water-permeable block with a thickness of 30 mm can reach 400 kg.
A transverse rupture strength of g is obtained. Incidentally, when laying the artificial turf pine 1-A, the water-permeable block 6 described above is not necessarily required, and the artificial turf pine 1-A may be laid directly on the ground 5.

Next, the operation of this embodiment will be explained.

In the artificial turf mat A of this embodiment, the flange 2 is
Since the flanges 2 are planted continuously in the length direction, the flanges 2 are arranged in a striped manner, and the intervals between the nodes are maintained at a constant width, making it easy to fill with the sand-like material 4. Moreover, the filled sand-like material 4 is stopped by the standing wall 11 and does not spill out from the mat member I.

Furthermore, since the thickness of the layer of sand 4 is determined by the depth (57 mm) from the top surface of the standing wall 11 to the top surface of the base 10, a stance feeling similar to that of natural grass can be obtained, and the flange 2 Since the flange 2 is planted on the top surface of the ridge 12, the protrusion length (30 mm) of the flange 2 is shorter than the height of the ridge 12 ( 30n
It becomes shorter by the length of time (on), which makes it more resistant to falling and bending.

Further, since the flange 2 is installed on the protrusion 10, the installation depth of the flange 2 (20 m+) can be increased. If the flange 2 were to be directly planted on the upper surface of the base IO, the planting depth would not be equal to the thickness (10 mm) of the base 10 at the maximum. In addition, since the root portion 20 of the flange 2 is connected by the knitting yarn 3,
The flange 2 becomes integral with each other, and strong resistance to the removal of the flange 2 is obtained.

Furthermore, when it rains, the rainwater percolates into the layer of sandy material 4 and then drains through the water permeable holes 14, so that no puddles form on the artificial turf mat A. still,
In the case of the construction example shown in FIG. 4, rainwater from the water-permeable holes 14 is immediately absorbed by the water-permeable blocks 6, so water on the artificial turf mat A can be absorbed extremely well. The rainwater absorbed by the block penetrates the inside of the permeable block 6 while being dispersed over a wide area, and is efficiently absorbed into the ground 5 from the bottom and sides.

Further, since the sand-like material 4 is solidified with a coagulant, the sand-like material 4 will not be scattered more than necessary when hitting the fifth ball, and a stable stance can be obtained because of the foothold.

In addition, the mat member l includes a base 10, a standing wall 11, a protrusion 12
Since it is a synthetic resin molded product with integral parts, it is easy to manufacture, and since the flange 2 is connected by the knitting yarn 3, there is no looseness or disorder of the flange 2 during planting work, and it can be arranged neatly. The flange 2 can be easily installed.

Next, an artificial turf mat according to a second embodiment of the present invention shown in FIGS. 5 and 6 will be described. In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted, and only the differences will be explained.

That is, the artificial turf mat A of this example has the mat member 10
Rubber is used as the material for the line grooves 12, 12, and the grooves between the protrusions 12, 12 are formed to have a semicircular cross section, and circular water permeable holes 14 are formed at the bottoms of the line grooves. In this embodiment, no standing wall is provided on the outer periphery of the mat member 10.

In addition, as shown in FIG. 7, the root portion 20 of the flange 2 is formed in an annular shape, and when the root portion 20 is buried in the protrusion 12, the rubber material of the same portion extends into the I-shaped gap. By being filled, the root portion 20 of the flange 2 is firmly connected and integrally fixed to the protrusion 12.

Further, a water-permeable elastic layer 100 is formed in the groove between each of the protrusions 12, 12, and the upper part of this water-permeable elastic layer 100 is filled with sand-like material 4. In this example, assimilation of the sand-like material 4 using a coagulant is not performed.

In this embodiment, as the water-permeable elastic layer 100, a structure is used in which a countless number of granular rubbers are bound and integrated with water-permeable spaces formed between each granular rubber. It is fitted between each protrusion 12.12.

In this embodiment, the planar shape of the mat member 1 is a square with the same length and width, the board thickness of the base 10 is 5 mm, the height of the protrusions 12 is 10 mm, and the height of each protrusion 12 is 5 mm.
, the pitch between 12 is 15I! I! 11. The protrusion length of each flange 2 is set to 25 mm.

Therefore, in the artificial turf mat A of this embodiment, when a load is applied to the upper surface of the filling sand 4, the water-permeable elastic layer 100 is compressed in response to this load, so that the filling sand 4 is compressed.
sinks downward, but when the load is released, the elasticity of the water-permeable elastic layer 100 pushes the filled sand-like body 4 back upwards. This will prevent solidification.

Further, when it rains, the rainwater permeates into the layer of the sandy body 4 and then passes through the water permeable holes 14 through the water permeable spaces formed between the granular rubber constituting the water permeable elastic layer 100. Since water is drained through the artificial turf mat A, there is no chance of water puddles forming on the artificial turf mat A.

Although embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to these embodiments.

For example, as for the method of planting the flanges, the root portions of the flanges may be buried in the protrusions at the same time as the mat member is formed.

In addition to the materials used in the examples, foamed plastic particles, sawdust, open-cell urethane ribbon, and the like can be used as the constituent material of the water-permeable elastic layer.

In addition to silica sand, perlite, shirasu balloons, sintered lightweight aggregate, synthetic resin particles, etc. can be used as the sand-like material to be filled.

Furthermore, although a case has been shown in which the base is integrally molded with a base that is a vertical wall, a vertical wall may be formed by attaching a frame member having a cross-sectional shape.

In addition, as an example of construction, we have shown the case of laying it on the teeing ground of a golf course, but it can also be laid alone on the batting area of a golf driving range, or you can create a butter golf course with artificial grass mats spread all over. In addition, it can be spread over the whole or part of each home's garden or kindergarten's garden.

(Effects of the Invention) As described above, the artificial turf mat according to claim 1 of the present invention provides the following effects.

In connection with the flanges planted on the protrusions, it becomes easier to fill the sandy material, so the sandy material can be packed densely, and the thickness of the sandy material layer can be reduced. It is possible to shorten the protruding length of the flange while increasing the depth, so you can get the stance of natural grass, and prevent the flange from falling over or bending, so it does not spoil the appearance. Since it can be planted deep, it can be planted firmly.

There are permeable holes in the base, so rainwater can drain and there is no chance of water puddles forming.

Since the base portions of the flanges are connected by knitting yarn, the flanges are integrated with each other, and have strong resistance against being pulled out and removed, and it is possible to prevent the flanges from becoming loose or disordered when they are planted.

Furthermore, in the artificial turf mat according to claim 2 of the present invention,
By interposing a water-permeable elastic layer with water permeability and elasticity between the base of the mat member and the filling sand, the load applied to the upper surface of the sand and the release of the load reduce the water-permeable elastic layer. The expansion and contraction action causes the sand-like body to move up and down, thereby providing the effect of preventing the sand-like body from solidifying.

Moreover, in the artificial turf mat according to claim 3 of the present invention,
Since the sand-like material is solidified with a coagulant, the sand will not scatter more than necessary when hitting the ball, and the footrest will provide a stable stance.

Moreover, in the artificial turf mat according to claim 4 of the present invention,
Standing walls were installed around the entire periphery of the foundation, so the filled sand would not spill out.
