DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to amusement parks, parks, hospitals,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creeping plant protection material for protecting creeping plants such as lawns in vegetation areas in exercise facilities or various other facilities, which protects these creeping plants from treading pressure of a person or a car.

[0002]

2. Description of the Related Art A creeping plant protection material is proposed by the present inventor, and is roughly classified into two types. One type has a tubular portion formed at each intersection of a lattice frame. There is a technique in which a creeping plant, such as a lawn, is laid on an area where vegetation, such as a lawn, is vegetated, to protect the creeping plant, such as a lawn, from human pressure. In another type, cylindrical depressions are erected at all intersections of the lattice-shaped substrate members, and ribs formed from the substrate members are formed between the adjacent depressions. Without digging down or digging down a predetermined area, these are arranged continuously in that area, the soil is laid between the treads of the arranged creeping plant protection material, and the soil is laid and spread, and then the upper part From the soil about 1cm thick for planting creeping plants such as lawns,
After a certain amount of chemical fertilizer is added, a creeping plant such as a lawn is placed thereon, rolled by a roller or the like, and pushed into the space between the treads and planted. A creeping plant such as a lawn planted between the treads is protected by the treads from the treads of a car or a person. That is, the former is of a type that protects against relatively light treading pressure like a pedestrian, and the latter is of a type that protects against heavy treading pressure like a car.

[0003]

SUMMARY OF THE INVENTION The present invention is to solve the latter problem of the above-mentioned prior art.
The latter protects creeping plants from the pressure of heavy objects such as automobiles for the first time, and therefore provides a parking lot or the like for the first time vegetation of creeping plants such as lawns. It is something that can be done. In that sense, it can be said that it is extremely innovative. However, in this creeping plant protection material, the soil surface on which the creeping plants are vegetated must be at the same height or slightly below the upper surface of the treads, and as a result, the treads of automobiles are mainly received by the treads. However, at the same time, the vegetation surface of creeping plants must be compacted to some extent. The present invention has as its main object to solve the above problems, and furthermore, in a vegetation area of a creeping plant, to prevent the growth of weeds and to facilitate the extension of runners in all directions. It is also what to say.

[0004]

The gist of the present invention resides in that a lower main frame is formed by arranging a plurality of openings vertically penetrating vertically on a plane as an average, and A plurality of protection pillars erected on the base frame, comprising protection pillars arranged on average from a plane so as to form a protection space for protecting creeping plants between them, and an upper auxiliary frame; At least a part of the protection pillar is a plurality of cylinder pillars positioned vertically corresponding to each other, and a cylinder pillar arranged to form an auxiliary protection space therebetween, and an upper part of the cylinder pillar mutually. An upper frame to be combined and a lower frame to mutually couple the lower part of the cylindrical column, and the upper auxiliary frame on the lower main frame,
This is a creeping plant protection material that is mounted on the latter cylindrical column corresponding to the former protective column, while externally ascending and descending.

[0005] The base frame may be formed as a frame, for example, in a lattice or honeycomb shape, and a rectangular or honeycomb gap in the frame may be used as the opening. Alternatively, the base frame may be formed of a plate material, and a plurality of circular or square holes may be formed as the openings in the plate material as described above on average when viewed from a plane. That is, any configuration can be adopted as long as it has the necessary components. The shape of the protective column is not limited. A column, a prism, a cylinder, a prism, a cross-shaped column, or the like can be freely used. Naturally, the arrangement is, on average, when viewed from a plane, for example, when a lattice-like member is used as the base frame, the arrangement is at a position corresponding to the intersection of the lattice. When a honeycomb-shaped member is adopted, it is arranged upright at each bent portion of the hexagon. It should be noted that the shape of the cylindrical column is also determined according to the shape of the protective column, as described later. For example, as described above, when adopting a configuration in which the protection columns are erected at the intersections of the lattice-like base frames, the protection space is configured to be surrounded by four protection columns at the four corners of each lattice. Is done. If it is a honeycomb-shaped member, it is constituted by being surrounded by six protection columns of each hexagonal bent portion around each honeycomb space.

It is appropriate that the same number of the cylindrical pillars as the protective pillars are arranged in correspondence with each other in a positional relationship viewed from a plane, but the number of the cylindrical pillars may be smaller than the number of the protective pillars. In the case of a small number, each position is thinned out to an average, and the remaining cylindrical columns are made to correspond to the protective columns in a positional relationship viewed from a plane. The cylindrical column is formed in a cylindrical shape that can be provided on the protective column. If the protection column is a column, it is formed into a cylindrical shape that can be externally lifted and lowered. It is appropriate to form stoppers on the outer periphery of the upper end of the protective column and the inner periphery of the lower end of the cylindrical column, respectively. It is appropriate that the height from the upper end to the lower end of the cylindrical column is about 10 mm. The upper frame and the lower frame are configured to have a sufficient gap that does not hinder the extension of the plant. In the upper frame, a ring-shaped stepping portion may be formed between the cylindrical columns as viewed from a plane.

[0007] The lower main frame is formed, if necessary, on its outer periphery with a connecting male portion and a connecting female portion for connecting adjacent ones to each other with a corresponding relationship. Similarly, the upper auxiliary frame can also be configured by associating a connecting male portion and a connecting female portion on the outer periphery thereof as necessary.

[0008]

The present invention is configured as described above and can be used as follows. For example, without digging or digging down the target area, crushed stone is first spread in the area to form a crushed stone layer at the bottom. Pile of sand is added as needed to create a flat layer of sand. A large number of the lower main frames are continuously arranged on the mountain sand layer. Adjacent ones, when constructed, are connected by their respective connecting male and female parts. On top of that, apply black soil or sand sand between the protection pillars of the lower main frame that was laid, spread them out, and then wipe off about 10 mm of the customer soil from the upper end of the protection pillars, and slightly use chemical fertilizer, etc. Is applied. After that, creeping plants, for example, lawns, are placed on their entire surface, and they are rolled with rollers and pressed into between the protection pillars. Apply a little more sand.

Thereafter, upper auxiliary frames are set on the laid lower main frames, respectively. Each of the cylindrical pillars of the upper auxiliary frame is set on the protective pillars of the lower main frame by externally ascending and descending. Thus, the upper auxiliary frame is placed on a creeping plant such as a lawn planted in the lower main frame or on the planting surface. In this way, the creeping plants such as the lawn are protected by the lower main frame and the upper auxiliary frame of the creeping plant protection material from the treading pressure of pedestrians walking above, vehicles parked or running, and the like.

First, a relatively light stepping force of a pedestrian or the like is received by the upper auxiliary frame. As described above, the upper auxiliary frame is in a state in which the lower frame rests on a creeping plant such as a lawn or on its planting surface, and when a pedestrian walks on this, the tread pressure is: First, it is received by the upper frame, and this is transmitted to the lower frame through the cylindrical column. As described above, the lower frame is in contact with the creeping plant such as the lawn and the planting surface thereof, and as much as the treading pressure, this lowers while pushing down the planting surface of the creeping plant. . Thus, the upper auxiliary frame distributes the treading pressure of the pedestrian walking on the creeping plant protection material to the whole, and transmits the creeping plant only at the lower frame to the planting surface of the creeping plant. By not transmitting to the surface, solidification of the planting surface is avoided as a whole and protection of creeping plants is aimed at. In addition, the upper auxiliary frame slightly moves up and down due to the elasticity of the planting surface of the creeping plant, so that a soft walking feeling can be obtained. As described above, since the upper auxiliary frame has its cylindrical column externally mounted on the protection column of the lower main frame so as to be able to move up and down, it is needless to say that it can be moved up and down.

When a heavy vehicle such as an automobile runs or parks on the crawling plant protection material, the lower frame of the upper auxiliary frame sinks below the planting surface of the crawling plant due to its weight. As a result, the upper end of the former cylindrical column and the upper end of the upper frame are substantially at the same height as the upper end of the latter protective column. Thus, the tread pressure of the heavy vehicle such as the automobile is received by the protection pillar, and the lower main frame is received instead of the upper auxiliary frame. As described above, since the lower main frame is for planting creeping plants in the protection space between the protection pillars, if the protection pillar can receive the treading pressure of the above-mentioned automobile or the like, there is a problem such as solidification on the planting surface. Does not exist. The treading pressure is received by the crushed stone layer and the like below the lower main frame. When a car or the like passes or moves from the parking position, the upper auxiliary frame rises due to the elasticity of the planting surface, and generally returns to the original position.

However, creeping plants may be subject to the pressure of a motor vehicle or pedestrian as a result of the grown leaves or stems extending above the guard post and further above the upper auxiliary frame. Since these planting surfaces are not compacted, it is possible to maintain a good growth state for a long period of time. From a further aspect, the creeping plant can run with its runners and the like freely extending through the auxiliary protection space between the upper frame and the lower frame of the upper auxiliary frame, and on the planting surface of the creeping plant. Since the upper auxiliary frame makes it difficult for sunlight to enter, there is also an advantage that growth of weeds is slowed down.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. Particularly, as shown in FIGS. 5 and 6, the lower main frame is formed. The protective pillars 1, 1,..., Which are cylindrical, are arranged vertically and horizontally on a substantially square base frame when viewed from a plane. In other words, they are arranged vertically and horizontally in five columns and five rows. The protection columns 1, 1,... Thus erected are joined by ribs 2, 2,. In the framework,
As described above, the ribs 2, 2,.
, An opening 3 penetrating the front and back is formed inside each of the square protection spaces surrounded by. Are formed on the outer periphery of the upper end of the protection pillars 1, 1,.

Further, on two adjacent sides of the base frame, an arm 6 is extended from each of a row of protective columns 1, 1... Located on both sides in a direction perpendicular to the side, and a connecting male portion 7 Is configured. As shown in FIGS. 5 and 6, the connecting male portions 7, 7,... It has a configuration having a groove reaching the upper and lower ends on the tip side. The arms 6, 6,... Have a length such that the distance between the centers of the protection pillars 1 from which the arms 6 extend and the coupling male portion 7 is the same as the distance between the centers of the adjacent protection pillars 1, 1. Determine the Furthermore, on the other two adjacent sides of the base frame, a connecting female portion corresponding to the connecting male portions 7, 7,... Is formed. Each of the protection pillars 1, 1,... Arranged on the corresponding side is formed with a cutout 8 for passing the arm 6 in a lower portion on a side orthogonal to the side so as to also serve as a coupling female part.

On the other hand, as shown in FIGS. 3 and 4, an upper auxiliary frame is formed. A plurality of cylindrical columns 4, 4,... Are positioned in the same arrangement as the protective columns 1, 1,.
Are connected to each other by an upper frame 10 composed of Respectively,
A tread ring 11 is formed at the intersection of one frame member 9 and the frame member 9 orthogonal to the frame member 9. Each of the cylindrical columns 4, 4
, The lower ends of the frame members 12 arranged vertically and horizontally,
.. Are connected to each other by a lower frame 13 composed of. The inner diameter of each of the cylindrical columns 4, 4,...
The outer diameter is slightly larger than that of the latter in order to be able to move up and down freely. A return 14 is formed at the lower end of the inner circumference. The direction of the return 14 is determined as shown in FIG. 4 so that it is not inconvenient to externally cover the cylindrical column 4 with the protective column 1 from the upper end.

In this embodiment, all the components of the lower main frame and the upper auxiliary frame are integrally formed of a plastic mainly composed of polypropylene.

In this embodiment, since the configuration is as described above, it is used as follows. It is a structural example of the parking lot of the lawn 17. The target area is dug down, and crushed stones are laid in the area to form a crushed stone layer 15 at the bottom as shown in FIG. Pile of sand is put on it to form a pile of sand 16 having a flat upper surface. A large number of the lower main frames are continuously arranged on the mountain sand layer 16. Adjacent mutuals, as shown in FIG.
Are connected by fitting the connecting male portions 7, 7... To the protection columns 1, 1,. After that, black soil is laid in the protection space between the protection pillars 1, 1, ... of the lower main frame that has been laid, and they are spread out, and then the protection pillars 1,
Remove about 10mm of soil from the top of 1 and apply some chemical fertilizer. Then, the lawn 17 is placed on the entire surface thereof, and is rolled by a roller to be pressed into the protection space between the protection columns 1, 1,. Further, the grass 17 is slightly sanded.

Thereafter, the upper auxiliary frames are set on the lower main frames laid as described above. Each of the cylindrical pillars 4, 4,... Of the upper auxiliary frame is set on the protective pillars 1, 1,. By pushing down the upper auxiliary frame corresponding to the protection columns 1, 1,..., The respective cylindrical columns 4, 4,. In the highest position, the return members 5 and 14 come into contact with each other to prevent slipping. At the time of loading, the former falls down to the outer circumference, and the latter falls down to the inner circumference, so that there is no problem in loading. 1 and 2
7 shows a state in which the upper auxiliary frame is set on the lower main frame together with FIG. Thus, the upper auxiliary frame is placed on the lawn 17 planted in the lower main frame.
Thus, the lawn 17 is protected by the lower main frame and the upper auxiliary frame of the creeping plant protection material from the tread pressure of a pedestrian walking above it and a car or a car parked or running.

First, a relatively light tread pressure caused by a pedestrian walking is received by the upper auxiliary frame. That is, the upper auxiliary frame has the lower frame 13 as described above,
When the pedestrian walks on the planting surface 18, the tread pressure is first received by the upper frame 10, which is passed through the cylindrical columns 4, 4,. Is transmitted to As described above, the lower frame 13 comes into contact with the lawn 17 and the planting surface 18 thereof, and the lower frame 13 descends while pushing down the planting surface 18 of the lawn 17 by an amount corresponding to the treading pressure. Thus, the upper auxiliary frame distributes the tread pressure of the pedestrian walking on the creeping plant protection material to the whole, and transmits the tread to the planting surface 18 of the lawn 17 only at the lower frame 13 and at the other portions. By not transmitting to the planting surface 18, solidification of the planting surface 18 is avoided as a whole, and the lawn 17 is protected. Further, the upper auxiliary frame is formed by elasticity of the planting surface 18 of the lawn 17.
A slight ascending and descending operation occurs, whereby a soft walking feeling can be obtained. It is needless to say that the upper auxiliary frame is vertically movable because the cylindrical columns 4, 4,... Are mounted on the protective columns 1, 1,.

When a heavy vehicle such as an automobile travels or parks on the crawling plant protection material, the lower frame 13 of the upper auxiliary frame is attached to the planting surface 18 of the lawn 17 due to its weight. Into the lower main frame, the upper ends of the former cylindrical pillars 4, 4,... And the upper end of the upper frame 10 become almost the same height as the upper ends of the latter protective pillars 1, 1,. Thus, the tread pressure of the heavy vehicle such as the automobile is
The protection pillars 1, 1,... Are received, and the lower main frame is received instead of the upper auxiliary frame. As described above, the lower main frame has its protective pillars 1, 1
The lawn 17 is planted in the protection space between the protection columns, and if the protection pillars 1, 1,... Can receive the treading pressure of the vehicle or the like, there is no possibility that a problem such as solidification of the planting surface 18 occurs. The treading pressure is further received by the crushed stone layer 15 and the like through the lower main frame. When a car or the like passes or moves from the parking position, the upper auxiliary frame is attached to the planting surface 18.
It rises due to the elasticity of the tire, and generally returns to the original height position.

Thus, the lawn 17 shows that their grown leaves or stems extend above the guard pillars 1, 1,. There is a possibility of receiving them, but their planting surface 1
8 is not compacted, so that a good growth state can be maintained for a long period of time. From a further aspect, the lawn 17 can travel with the runners and the like freely extending in the space between the upper frame 10 and the lower frame 13 of the upper auxiliary frame, and the planting surface 18 can support the upper auxiliary frame. Since the frame makes it difficult for sunlight to enter, there is also an advantage that growth of weeds is slowed down.

[0022]

According to the present invention, a creeping plant such as a lawn is
The upper auxiliary frame and the lower main frame protect the pedestrian and the vehicle from treading pressure and prevent solidification of the planting surface, so that a good growth state can be maintained for a long time. The upper auxiliary frame has its cylindrical column mounted on the protection column of the lower main frame so as to be able to move up and down, and the lower frame is placed on the planting surface of the creeping plant. When the person walks, the person descends according to the treading pressure, and rises when passing. Thus, the walking feeling of the pedestrian can be improved. When a heavy vehicle such as an automobile is parked or passes, the upper auxiliary frame is lowered by the weight of the automobile, and the upper end of the upper frame coincides with the upper end of the protection pillar. The weight of the vehicle is thus received by the protection pillar of the lower main frame, which is further received by the crushed stone layer 15 and the like via the mountain sand layer 16. Since the creeping plant is planted in the protection space between the protection pillars,
The stepping pressure is not received, the planting surface is prevented from being solidified, and a good growth state can be maintained for a long period of time. Runners and the like of the creeping plant can travel by extending the auxiliary protection space between the upper frame and the lower frame of the upper auxiliary frame.
