[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is used not only for all seasons at baseball fields and soccer grounds, but also for temporary exhibitions at exhibitions, exhibitions, and other event venues, such as entrances, for a predetermined period of time. Relates to a hybrid lawn sheet that is used in the past.

[0002]

2. Description of the Related Art Conventionally, a green area or a spectator seat of a ball field such as a baseball field or a soccer ground, or a tee ground of a golf course is complicated in terms of maintenance and cost.
In recent years, the use of artificial turf has been mostly used.

However, in the above-mentioned exhibitions and exhibitions, an environment in which green is emphasized is often created,
For example, when the theme is environmental problems or pollution problems, it is often the case that the use of artificial grass is avoided and natural grass is planted to create the atmosphere of the venue.

However, the above-mentioned natural lawn is very costly to maintain because it is complicated to maintain as described above, and there is a problem that the cost increases considerably as the area increases.

Therefore, it was devised to use the artificial grass and the natural grass in a mixed state. For example, as shown in FIG. 6, a natural lawn 3'developed by the inventor of the present application was ground 9 '
There is an artificial turf 2'knitted by Russell weave or the like on the upper surface thereof (see Japanese Patent Laid-Open No. 4-207123).

[0006]

[Problems to be solved by the invention] However, the artificial turf
In the case of a mixture of 2'and natural turf 3 ', all the construction work must be done on-site.First, the seed of natural turf 3'is planted on the ground of the site, and then the natural Turf 3'bud
The artificial turf 2'has to be laid so that the 11 'can pass through, and due to the size of the site area, the construction work took a very long time, and the work could not be performed smoothly.

Furthermore, once the natural turf 3'is on the ground 9'as described above.
When planted in, the root 10 'of the natural grass 3'is fixed to the ground 9', so even after the event is over, the lawn can hardly be removed from the place, After the end, it was just released as it was.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is intended to create an atmosphere based on natural grass, and its operation is very easy, and it is performed for a predetermined period. It is an object of the present invention to provide a hybrid lawn sheet composed of a mixture of artificial grass and natural grass that can be reused even after use.

[0009]

[Means for Solving the Problems] The technical means taken by the present invention to solve the above-mentioned problems are the cutting grass on the upper surface of the base sheet 1 having the air insertion space 5 in which the roots 10 of the cutting grass 3 intertwine. 3 is laid and the pile thread 6 is placed on the upper surface of the cut grass 3.
It is characterized in that an artificial turf sheet 2 constructed by weaving the above into a coarse stitch 7 is laid.

[0010]

[Function] In the hybrid lawn sheet of the present invention, the root 10 of the cut grass 3
A base sheet 1 having an air insertion space 5 in which
Since the cut grass 3, that is, the dry grass in the dormant state is laid between the artificial grass sheet 2 formed by weaving the pile yarn 6 into the coarse stitches 7, the mixed grass sheet of the present invention can be used in advance. By placing the artificial turf sheet 2 side as the upper surface on the ground 9 at the site, and setting the environment to satisfy the growth factors (for example, light and water), the entire surface of the cut grass 3 becomes the growth point,
3 roots in a state of being entwined with the air insertion space 5 of the base sheet 1, and also germinates by passing between the pile yarns 6 woven in the stitches 7 of the artificial grass sheet 2.

As described above, the air insertion space 5 of the base sheet 1 and the stitches 7 of the artificial turf sheet 2 greatly improve the air permeability of the base sheet 1,
Cut grass 3 sandwiched between 1 and artificial grass sheet 2 roots and germinates easily and in a short time.
First, the sprouts 11 are activated in a state of being entangled with the artificial turf sheet 2, so that the growth rate is very good, and it is a sturdy and stable hybrid lawn sheet. By pulling in the direction, the entire hybrid lawn sheet can be peeled off the ground 9.

[0012] Therefore, if the rolled grass sheet is directly transported and shipped to the necessary event site in the roll state, and the mixed grass sheet is laid again at the site, the cut grass 3 is easily rooted on the ground of the site and planted. To be done.

When the lawn is no longer needed at the site, the root 10 of the already activated cut grass 3 is intertwined with the mesh sheet 1 so that the mesh sheet 1 can be simply pulled. It can be easily removed and can be transported to the next site for reuse.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The hybrid lawn sheet according to the present invention, as shown in FIGS. 1 and 2, has a grid-like stitch as a base sheet 1.
A synthetic resin mesh sheet 1a having 5a (which becomes the air insertion space 5) is used, and an artificial grass sheet is placed on the upper surface of the mesh sheet 1a.
2 is laid, and natural loosened cut grass 3 is sandwiched between the mesh sheet 1a and the artificial grass sheet 2.

The mesh sheet 1a is made of polyethylene,
It is made of composite fiber yarn 4 made of polypropylene, polyester, etc., which is very weatherable and has a mesh shape of about 5 mm.
² to 5 cm ^2, stitches preferably of 1cm ² ~3cm ² size of
Base sheet of a certain size by continuously and firmly knitting 5a
It is one.

When the cut grass 3a is composed of the above-mentioned size, the air permeability and elasticity of the air when the cut grass 3 is laid are very good, and the rooting and germination of the cut grass 3 takes a short time. Along with that, the growth rate also improves.

The artificial grass sheet 2 is made of pile yarn 6
Is woven in a coarse stitch 7 shape using Russell weaving,
When the cut grass 3 is activated and grows, the lower surface side of the cut grass 3 is continuously knitted to such a degree that the shoots 11 of the cut grass 3 can pass through, or is connected by another fiber thread. A sheet of a predetermined size is formed in a grass shape by cutting the tip portion 8 of the pile yarn 6 on the upper surface side.

As the pile yarn 3, a monofilament or yarn made of polypropylene, polyethylene, nylon, polyester, polyvinylidene chloride, polyvinyl chloride or the like is used, and its pile length is 5 mm or more, preferably
10 to 50 mm and total denier of 1,200 to 12,000 d,
Preferably, those having 2,500 to 8,500 d are used.

The natural cut grass 3 is a dry grass in a dormant state and is usually called a runner. It is carefully loosened and juxtaposed on the upper surface of the mesh sheet 1a.
If the entire surface becomes a growth point and essential growth factors such as water and soil are prepared, healthy germination and rooting will start from all nodes.

When actually using the hybrid lawn sheet configured as described above, for example, by utilizing a resting field or vacant land, first lay the mesh sheet 1a on the ground 9, Next, the carefully cut loose grass 3 is laid on the upper surface of the mesh sheet 1a, the artificial grass sheet 2 is further laid on the upper surface of the cut grass 3, and soil may be slightly covered in this state. Give water.

Then, the spaces between the meshes 5 of the mesh sheet 1a and the stitches 7 of the artificial turf sheet 2 become the air insertion space 5, and the air permeability is greatly improved.
As shown in FIG. 2, the roots 10 pass between the meshes 5 of the mesh sheet 1a to take roots easily and in a short time due to the gravity and light-reflecting property of the cut grass 3, and the sprouts 11 are The artificial grass sheet 2 passes through the stitches 7 of the woven pile yarn 6 to germinate and be activated in a well-balanced manner.

After that, in a short period of time, the root 10 is entangled with the mesh sheet 1a and the sprouts 11 are entangled with the artificial grass sheet 2, and after this state, the mesh sheet 1a is pulled, thereby As shown in, it is possible to peel off the entire mixed lawn sheet from the ground 9 and wind it in a roll.

Therefore, if the mixed lawn sheet wound in the roll state is directly transported and shipped to a necessary event venue or the like, cut into an appropriate size, and the hybrid lawn sheet is laid again on the ground of the venue, The activated cut grass on the ground
The root 10 of 3 is rooted through the mesh sheet 1a,
3 is reactivated and planted.

When the roots 10 and the shoots 11 of the cut grass 3 activated in the sheets 1 and 2 at one end as described above are entangled with each other, the mixed lawn sheet can be freely removed, and the above-mentioned event is performed. When finished and the need for the hybrid lawn sheet is no longer needed, the mesh sheet is always available.
It can be easily removed simply by pulling off 1a, and the removed mixed lawn sheet can be rewound around the roll core 12 or the like and transported to the next site for reuse.

Therefore, the hybrid lawn sheet according to the present invention is
Not only when it is used all-season at a baseball field or soccer ground, but also when it is temporarily used only during a predetermined period, such as at an exhibition, exhibition, or other event venue, such as an entrance. , Can be used easily.

At this time, even if the activated cut grass 3
Since the green state can always be maintained by the artificial turf sheet 2 even when the seeds have withered, it is not necessary to take special care not only for short-term use but also for long-term use. Even without the mesh sheet
It can be easily repaired by simply sandwiching and refilling a new cut grass 3 between 1a and the artificial grass sheet 2, so that it can be used semi-permanently at any time and in any place.

The base sheet 1 is not limited to the mesh sheet 1a. For example, as shown in FIG. 4, the base sheet 1 is made of the same material as the artificial grass sheet 2 and is provided at an interval of 1 to 2 cm. The pile yarn 14 may be folded back and forth between the two layered base fabrics 13, 13 and the air insertion space 5b may be provided between them to form a woven sheet 1b, or as shown in FIG. It may be a stitch sheet 1c in which fiber yarns are three-dimensionally formed into stitches 5c. In short, the root of the cut grass 3 is essential.
A sheet having any structure may be used as long as 10 can be intertwined with each other and has a space 5 through which air can be inserted and is strong against weathering.

[0029]

The hybrid turf sheet of the present invention has natural loosened grass laid on the upper surface of the base sheet having an air insertion space where the roots of the grass are entwined, and pile yarn is laid on the upper surface of the grass. Since it is constructed by laying an artificial grass sheet that is woven into a coarse mesh, when the mixed grass sheet is placed on the ground, the root of the cut grass is in the air insertion space of the base sheet. It can be a hybrid lawn sheet in which buds are planted on the ground through the base sheet by entanglement and aeration, and the buds are moderately entangled with the artificial turf sheet and integrally connected.

In addition, in the green state of both the cut grass and the artificial grass sheet, it is possible to enjoy the all-season green without stopping, and even if the cut grass has withered, it can be used as the base sheet. Since repair can be done by a simple operation of just replenishing new cut grass between artificial grass sheets, one sheet can be used semipermanently.

Further, the hybrid lawn sheet according to the present invention can be removed very easily by pulling the base sheet, so that it can be used at temporary exhibitions, exhibitions and other event venues. When it has been used and the event is over and the need for the hybrid turf sheet is no longer needed, it can be removed at any time, and the removed hybrid turf sheet is transported to the next venue again and re-loaded. It can be used.

In particular, when a synthetic resin mesh sheet having a stitch size of about 5 mm ^{2 to} 5 cm ² is used as the base sheet, it is very strong against weathering and
Since the air insertion space is maintained in a well-balanced manner, it can be used without any problems even when it is recycled several times.

Further, since the mixed lawn sheet can be wound into a roll, it is easy to carry and
Since it can be used by appropriately cutting it into a size according to need, it is possible to easily perform construction work at any place and on any site area.
