Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a lawn pine that is laid on a lawn and is intended to prevent damage to the lawn caused by walking as much as possible.

(Prior technology) In areas where grass is planted, such as golf courses, where people frequently walk, the grass is damaged by trampling, and the ground is compacted, eventually causing the grass to wither and the surface of the soil to be exposed. Was.

Therefore, in the past, perforated grass pine or other matting was laid down on the lawn to protect it.

There was also a pine with protrusions on its surface (Utility Model Application No. 39347/1983).

Also known is a vegetation protection board in which a ventilation tube is provided at the intersection of the frames (Utility Model Publication No. 62-9799).

(Problem to be solved by the invention) However, with conventional lawn pine, the pores are not only small but also have a flat surface, which prevents direct damage to the grass roots from sewage such as spikes. There is a problem in that the leaves of the grass are damaged by being trampled and sometimes twisted between the underside of the shew and the surface of the pine.

Also, even if the pine has protrusions on the surface,
Since the area of the perforations was significantly smaller than the area of other parts, it was difficult to grow the lawn in a healthy manner.

In addition, in the case of a pine in which ventilators are connected at appropriate intervals, the weight of the person may cause the ventilator to be inserted into the soil, and the top surface of the ventilator may eventually become almost equal to the soil surface, reducing the effectiveness of the pine. Ta.

(Means for Solving the Problems) In order to solve the above-mentioned problems, this invention aims to create a plurality of rectangular through holes in a staggered pattern that penetrates the front and back surfaces of a flat pine that is laid on a lawn. The above-mentioned problems of the conventional method were solved by forming a large number of protrusions on the front surface and forming a flat surface on the back surface to prevent insertion into the soil.

In addition, the shape and number of the protrusions are not limited, but there is sufficient space (the recess between the protrusions) to accommodate the grass blades protruding from the hole, and there is also a space for direct use of spikes and other spikes. The spacing and shape should be such that support does not hinder walking.

That is, in this invention, in a flat pine having through-holes laid on a lawn, the through-holes are rectangular and arranged in a staggered manner, and a large number of protrusions are formed on the surface of the pine, The lawn pine is characterized in that the upper surface of the short side wall forming the connecting portion of the through hole is formed lower than the upper surface of the projection. Further, the number of protrusions is set at a density sufficient to support the sole of the shoe during walking.

(Function) According to this invention, by laying the lawn pine on the lawn, the lawn protrudes from the rectangular hole, so it is not crushed by the pine and therefore its growth is not hindered. In addition, when walking on this pine, spikes and other shoes are supported by the protrusions, and the grass blades protruding from the holes are inserted into the gaps (spaces) between the protrusions. It was stored, and this became a place of escape.
Prevents damage to grass caused by trampling by grass such as grass.

(Example 1) An example of this invention will be described below based on FIGS. 1 to 3.

A large number of rectangular through holes 2 whose long sides are in the longitudinal direction are formed at regular intervals in a rectangular flat plate 1 made of rubber.
They are provided in a staggered manner so as to be offset by half the length in the width direction of the flat plate 1.

In this way, the adjacent through holes 2, 2 are arranged in parallel.
The long side walls 2a, 2a are parallel to each other, and truncated quadrangular pyramid-shaped protrusions 3 are formed at regular intervals in the longitudinal direction on the surface side between the long side walls 2a, 2a.

Therefore, the surface side space 5 between the projections 3, 3 is continuous with the through holes 2, 2.

Moreover, the upper part of the short side wall 2b of the through hole 2 is formed with an inclined surface 2c, and no protrusion is provided between the short side walls 2b of the adjacent through holes 2,2. Moreover, the surface of the long side wall 2a is designed to be as low as possible without any protrusions. Further, the upper surface of the short side wall is formed lower than the upper surface of the protrusion.

The back surface (not shown) of the flat plate 1 is a flat surface except for the through holes 2.

The state of use of this invention will be explained below.

The lawn pine constructed as described above is laid on the lawn.

Since the grass sprouts its leaves from within the large number of through holes 2, 2, it propagates relatively easily and is relatively less likely to be blocked by the underside of the pine.

Therefore, the growth of the grass is less hindered, and the long leaves 4 of the grass protrude from the hole 2 (as shown by the chain line in FIG. 2). In this state, even if you walk on the mat with the shoe 5 equipped with spikes, its lower surface is supported by the upper surface of the protrusion 3, and the protrusion 3,
The space above the surface of the mat except for 3 is secured as a gap.

There, the grass leaves were forced to protrude from the hole 2,
While being pressed by the shoe 5, it is guided into the gap created by the projections 3, 3, and the shoe 5
Since the grass is not crushed by the sole of the shoe and the surface of the mat, a place for the grass to escape is secured, so there is no damage to the grass. The gap is formed by adjacent through holes 2,
2. Both the long side and the short side are continuous, so that the escape area of the grass is not contained. Further, since the protrusion 3 has a truncated quadrangular pyramid shape and has sloped side surfaces, the grass leaves 4 can be quickly and easily introduced into the gap.

Note that after walking, the grass leaves 4 stored in the space will return naturally, so there is no risk of inhibiting growth.

In addition, if the above-mentioned lawn pine is placed upside down on a flat floor surface such as concrete or a board, the pine will be supported by the protrusions, and the protrusions will create a water passage on the bottom surface. This ensures good drainage, resulting in a rug that has the same effect as slats.

Furthermore, with this invention, protrusions can be provided not only on the front surface but also on the back surface. If such pine is laid on the lawn, drainage will be improved and the back of the pine will have a place for the grass to escape, which will effectively prevent the lawn from being crushed by the back of the pine. There is.

(Embodiment 2) Next, another embodiment of this invention will be described based on FIGS. 4 to 6.

This embodiment has the same basic structure as the first embodiment, but differs in that the through holes provided in the mat are larger on the front side and smaller on the back side. That is, in a rectangular flat plate 1 made of rubber, a large number of rectangular through holes 2 whose long sides are in the longitudinal direction are bored at regular intervals in a staggered manner. The through hole 2 is formed in the flat plate 1
Make the front side larger and the back side smaller.
The long side wall 2a of the through hole is formed into a tapered shape (FIG. 6). By forming it in this way, the grass blades 4 can be bent more easily and fit into the gap 5. The connection surface 6 between each of the through holes 2 (in the width direction) is formed lower than the top surface of the protrusion 3 (FIG. 5).

There is no particular limitation on the inclination angle of the long side wall of the through hole in the above embodiments. An angle of about 10 to 30 degrees is often used.

(Effects of the invention) As explained above, according to this invention, a large number of rectangular protrusions are formed in a staggered manner in the flat pine that is laid on the lawn, so that the grass grows from inside the through-holes. , and there is no risk of inhibiting the growth of the grass by fitting it into the gap, and if the front side of the hole is made larger and the back side is made smaller, a place for grass leaves to escape when walking is secured, and the grass grows. This has the effect of preventing leaf damage as much as possible.

Furthermore, since the rectangular through holes are arranged in a staggered manner, the short side walls are also necessarily arranged in a staggered manner. Therefore, there is an effect of reliably preventing the long side walls from collapsing due to trampling.
