Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of a method of laying plants with stems, such as lawns, in areas where these plants are planted in order to protect them from trampling pressure from people, cars, etc. It concerns a creeping plant protection frame.

[Prior Art 1] The technology related to the above-mentioned creeping plant protection frame is based on the invention of the present inventor, and has been commercialized and provided to the market.

To describe its structure generally, it is plate-shaped as a whole,
Assemble the frame so that it can be freely ventilated in the thickness direction,
An annular body is constructed at each intersection of the frame, and legs extending downward and hanging are constructed at appropriate positions among the annular bodies.

These front plant protection frames are mainly used to protect lawns, and can be placed in series on a grassed area, or these front plant protection frames can be laid in a predetermined area and then placed on top of it. Grass is placed on top of the protective frame and then compacted to grow vegetation under the protective frame, which is then used for its protection. When the above-mentioned side plant protection frame is laid on a lawn vegetation area, the tread pressure of a person walking there or a car driving there is first applied to a part of the frame of the above-mentioned side plant protection frame, and this is connected. The pressure is widely transmitted to the many other frames installed, and the pressure is dispersed and applied to the ground. Therefore, this position of the vegetation is not pressed too hard and its solidification is prevented.

By the way, continuing with the example of a lawn, a lawn is made up of a collection of individual turfgrasses, and although these turfgrasses are perennial plants that belong to the species, many of them form underground rhizomes, and their roots are
It has the characteristic that it reproduces by extending in a ring shape from the leaf sheath.

In breeding this turfgrass and creating a lawn, the most important conditions are sunlight and soil structure. -Essentially, the development of plant roots is normally proportional to the development of the above-ground parts.
For this reason, plants such as lawns whose above-ground parts are constantly mowed and trampled have poor development of both leaves and roots, and require a lot of sunlight to carry out metabolic processes such as photosynthesis. In addition, grass is a plant that inherently dislikes moisture, so it is necessary to avoid moisture in the soil and improve ventilation.
The soil structure is also considered to be 50% soil particles and 50% pores, with the pores containing at least 25% air. If these environmental conditions are not sufficiently maintained, it will be difficult for turfgrass to reproduce, and even if it does reproduce, it will wither and die early.

When creating a lawn from the above points,
Choose a location with as much sunlight, ventilation, and drainage as possible, and if these conditions are not adequately maintained, artificial measures such as securing drainage channels or improving the soil structure should be taken. Grass is planted after conditions have been established. However, no matter how well conditions are prepared at the beginning of planting, the ground is covered with grass, and as mentioned above, when it is trampled and compacted by people, cars, and other heavy objects,
The air permeability of the ground is inhibited, and excess warm air becomes constantly stagnant, while the soil structure is also destroyed, and the pores in the soil become submerged and cannot hold enough air. On the other hand, as grass grows, its leaves cover the entire ground, making it extremely difficult to improve the deteriorating growing conditions. However, it is impossible to distribute air over a large area using this method.

Therefore, the growing conditions gradually deteriorate over time, causing the growth of mold and bacteria that cause disease, or the lack of air in the soil, which inhibits metabolism and causes the grass to wither prematurely. This can also lead to problems.

As mentioned above, the front plant protection frame solves these problems in the conventional method by widely dispersing the weight of people and vehicles stepping on it, preventing the destruction of soil pores, and preventing the destruction of grass, etc. This problem has been solved by ensuring ventilation between the plants and the ground.

[Problems to be Solved by the Invention] Although the above-mentioned side plant protection frame has achieved excellent effects in terms of the above-mentioned basic objectives, it has also been found that it has some drawbacks. In other words, the feeling of walking becomes slightly heavier for people walking on it. It may seem like a trivial thing, but it is important to ensure that the feeling of walking is as natural as walking on dirt.

An object of the present invention is to provide a side plant protection frame that provides a soft walking feeling by solving the above problems while retaining the advantages of the conventional crawler plant protection frame.

[Means for Solving the Problems] The gist of the configuration of the present invention is to configure a frame that is plate-shaped as a whole and to be able to ventilate freely in the thickness direction, and to form a frame that has a plurality of intersection points. The legs are suspended from a plurality of intersection points, and each of the legs is attached to a support plate placed in an area where side plants are grown,
This is a creeping plant protection frame that is combined with elasticity in the upward direction.

The frame can be configured, for example, in a lattice shape. Of course, the purpose is not limited to this.

Further, it is appropriate to construct an annular body at the intersection of the frames.

The leg body hanging down from the intersection of the frames can be configured, for example, in a cylindrical shape having a locking turn on the outer periphery of the lower end. Further, the support plate material is formed into a cylindrical body into which the leg can be inserted, and a locking slit is formed at the lower part of the corresponding side, through which the locking barb of the inserted leg enters and is locked at the upper end. make it stop. The above-mentioned locking slit shall have sufficient space downwardly.

Furthermore, an elastic member having an acting force is arranged at the upper end of the support plate of the cylindrical body to raise the frame, and a support plate with a large number of through holes is provided at the lower end of the support plate of the cylindrical body. It shall be fixedly installed at the location where it will be installed. Of course, other configurations may also be used.

[Function] Since the creeping plant protection frame of the present invention has the above structure, it can be used in the following manner.

Here, we will briefly explain this using a lawn as an example.

First, the ground in the target area is dug up and tilled, the soil clods are crushed into small pieces to make them as soft as possible, and the tilled soil is then exposed to sunlight for several days to weather. Thereafter, organic fertilizers and the like are applied, the soil is sterilized and disinfected as necessary, and soil conditioners are added as the case may be. After this, dig down a little and level the ground in the target area as much as possible. The upper soil will be set aside outside the area.

Next, an appropriate number of protective frames are prepared depending on the size of the area to be created, and these are laid in series over the entire area of the leveled ground as described above.

Next, the soil set aside above these protective frames is poured in, and then the lawn is placed above the protective frames. Since the grass is floating in this state, it will be further compacted and pushed into the lower part of the protective frame. This is how they are planted in the soil under the frame.

After this, work such as watering is carried out according to general techniques, and the work of planting the lawn using the front plant protection frame is completed.

The thus-planted lawn is protected by the creeping plant protection frame from the trampling pressure of people and vehicles due to the above-mentioned effect.

On the other hand, since the frame is elastically supported by the support plate material, pedestrians or vehicles walking on the frame have the advantage of having a softer walking or running feeling.

First, the ground in the target area is dug up and tilled, the soil clods are broken down as finely as possible to make them soft, and the tilled soil is then exposed to sunlight for several days to weather. Afterwards, apply organic fertilizer, etc., and sterilize the soil as necessary. Also, depending on the case, a soil improvement material or the like is added to the soil.

After this, the ground in the target area is leveled as much as possible while digging down a little. The upper soil will be set aside outside the area.

Next, an appropriate number of protective frames are prepared depending on the size of the area to be created, and these are arranged in series on the leveled ground as described above. Adjacent mutual protective frames connect the connecting male part 6.6 of one frame 1 to the connecting female part 7.7 of another frame 1.
They are arranged by fitting them together and connecting them to each other. In this way, a protection frame is placed in the entire target area.

Then, from above these protective frames, the soil that had been set aside earlier is poured in evenly until the top surface of the soil reaches just below the frame l. Next, the lawn 13 is placed over the entire surface of the frame 1 of the protective frame, and by rolling the lawn 13, the lawn 13 floating from the soil is pushed under the frame 1 and planted in the soil.

That is, it is as shown in FIG.

After this, work such as watering is performed according to general techniques, and the work of planting the lawn 13 using the front plant protection frame is completed.

Thus, the planted lawn 13 is protected by the frame 1 from the tread pressure of people and vehicles.

On the other hand, a pedestrian or a vehicle walking on the frame l is placed on the upper end of the support cylinder 9.9- and the disc spring body 11.1
