FIG. 3 is a conceptual diagram showing a third example of the plant protection material constituting the first invention.
FIG. 3a shows the plane and cross section of the upper frame, and FIG. 3b shows the plane and cross section of the lower frame. FIG. 3c is a cross-sectional view showing a state in which the lower frame and the upper frame are connected.
As shown in FIG. 3a, the upper frame has a cylindrical treading pressure portion connected by a beam portion, the side wall of the cylindrical portion becomes the upper treading pressure portion, and the inside of the cylinder becomes the upper water-permeable portion. In order to reduce the reaction force from the treading pressure, the upper part of the tube part may be closed leaving a hole for water permeability. The lower part of the upper pedaling part can be inserted into the cylinder of the lower pedaling part, and a barb for connecting the lower frame and the upper frame is provided. In addition, the connection part which connects upper frames is not provided.
The lower frame is a square partition frame, and the partition wall of each partition forms a lower treading portion, and the interior of the partition forms a lower water permeable portion. A joint for connecting the lower frames to each other is provided at the bottom of the side surface of the lower frame. The connecting portion shown in the figure is the same as the connecting portion described above, but is not limited to this connecting method, and an existing connecting method can be selected.
図1、図3に示す植物保護資材では、上部踏圧部と下部踏圧部および上部透水部と下部透水部が一対一に対応しているが、図2に示す植物保護資材は上部踏圧部と下部踏圧部は一対一には対応していない。上部踏圧部の一部は土壌により支持されるため下部踏圧部上に存在しなくてもよい。このとき、下部踏圧部上に存在しない上部踏圧部の底部を土壌面との距離が保たれるよう、高く即ち、上部踏圧部の厚みを下部踏圧部上に存在する上部踏圧部より減じておくこともできる。こうすることで本芝生保護資材を用いて施工する際、下部枠を敷設し、土壌を下部枠内の透水部内に充填し、転圧してから上部枠を接続するが、上部踏圧部の下に隙間があるため転圧を省略あるいは簡略化することができる。 In the plant protection material shown in FIG. 1 and FIG. 3, the upper treading pressure part and the lower treading pressure part and the upper water permeation part and the lower water permeation part correspond one-to-one, but the plant protection material shown in FIG. The treading portion does not correspond one-on-one. Since a part of the upper pedaling portion is supported by the soil, it may not be present on the lower pedaling portion. At this time, the bottom of the upper treading part that does not exist on the lower treading part is high, that is, the thickness of the upper treading part is reduced from the upper treading part that exists on the lower treading part so that the distance from the soil surface is maintained. You can also. In this way, when constructing using this lawn protective material, the lower frame is laid, the soil is filled into the water permeable part in the lower frame, and the upper frame is connected after rolling, but under the upper treading part Since there is a gap, the rolling pressure can be omitted or simplified.
図1ないし図3に示す植物保護資材の上部枠をゴム、エラストマーなどの弾性のある物質で形成することができる。材質を弾性体に変えることにより上部踏圧部より人の足にかかる反力が軽減されるため子供たちが運動する校庭などの芝生保護に優れた効果を発揮する。 The upper frame of the plant protection material shown in FIGS. 1 to 3 can be formed of an elastic material such as rubber or elastomer. By changing the material to an elastic body, the reaction force applied to the person's feet from the upper treading part is reduced, so it has an excellent effect in protecting lawns such as schoolyards where children exercise.
図4は、本第2の発明を構成する植物保護資材の踏圧部の概念図である。
図4aは上部踏圧部の平面および断面、図4bは下部踏圧部の平面および断面、図4cは上部踏圧部を下部踏圧部に接続した状態を示す断面図である。第1の発明と同様上部枠は上部踏圧部を梁部で連結したものであり、下部枠は下部踏圧部を梁部で連結したものであるため踏圧部の図で説明する。なお、上部枠と下部枠との接続、下部枠同士の連結、上部枠間の連結部のないことなど上記と同様である。
図示したように上部踏圧部は筒状であり、筒状部の内部に十字形の硬い支持部と柔らかい支持部が設けられている。図では柔らかい支持部は硬い支持部の側面に設けられているが、独立に設けてもよい。柔らかい支持部と硬い支持部は、例えば同質樹脂製でその厚みを変えることで実現できる。
硬い支持部は下部踏圧部の頂部に設けた溝に嵌るようになっている。柔らかい支持部は下部踏圧部の頂部に直に接するように設けられている。また上部踏圧部と下部踏圧部とを接続する接続部が一部の上部踏圧部に設けられている。
下部踏圧部は戴円錐形状の筒部であり、その筒部の一部はその頂部に固い支持部を嵌めるための溝が設けられ、図では十字形の溝となっている。また他の頂部は上部踏圧部に設けた継手部を嵌めるメス継手となっている。
人の踏圧がかかると上部踏圧部の柔らかい支持部がたわみ、人の足にかかる反力を軽減できるようになっている。また車などの重量物が通過する場合は硬い支持部でその荷重を受けられるようになっている。

As in the first aspect of the invention, the upper frame is formed by connecting the upper treading portion with the beam portion, and the lower frame is formed by connecting the lower treading portion with the beam portion. In addition, it is the same as that of the above, such as the connection of an upper frame and a lower frame, the connection of lower frames, the absence of the connection part between upper frames.
As shown in the drawing, the upper stepping pressure portion is cylindrical, and a cross-shaped hard support portion and soft support portion are provided inside the cylindrical portion. In the figure, the soft support portion is provided on the side surface of the hard support portion, but may be provided independently. The soft support portion and the hard support portion are made of, for example, a homogeneous resin and can be realized by changing the thickness thereof.
The hard support portion is adapted to fit into a groove provided at the top of the lower stepping pressure portion. The soft support portion is provided so as to be in direct contact with the top portion of the lower stepping pressure portion. Further, a connection portion that connects the upper pedaling portion and the lower pedaling portion is provided in some upper pedaling portions.
The lower treading pressure portion is a cone-shaped cylindrical portion, and a portion of the cylindrical portion is provided with a groove for fitting a hard support portion on the top thereof, which is a cross-shaped groove in the drawing. Moreover, the other top part is a female joint which fits the joint part provided in the upper stepping pressure part.
When a person's treading pressure is applied, the soft support part of the upper treading pressure part bends so that the reaction force on the person's foot can be reduced. In addition, when a heavy object such as a car passes, the load can be received by a hard support portion.
上記第1、第2の発明も含め上部踏圧部を連結する梁部は上部踏圧部頂部より一定の距離以上に定めることができる。
本芝生保護材上でスパイクなどを履いた運動をする場合スパイクの刃が上記梁部にかからないように、上部踏圧部頂部から梁部頂部間の距離を調整することもできる。
Including the first and second inventions, the beam portion connecting the upper treading pressure portion can be determined at a certain distance or more from the top of the upper treading pressure portion.
When exercising with spikes or the like on the lawn protective material, the distance between the top of the upper treading portion and the top of the beam can be adjusted so that the blade of the spike does not hit the beam.

The lower frame has a shape in which square tubes are connected, and the frame of each square tube corresponds to the lower treading portion, and the inside of the tube corresponds to the lower water permeable portion.
上記植物保護資材の接続部は上部枠の上部踏圧部下端に設けたオス継手と下部踏圧部頂部に設けたメス継手からなる。上部枠の梁部で上部枠が下がることはなく、継手部で互いに契合しているため上部に動くことはない。
スパイクを使用するような場所においては、上部踏圧部をつなぐ梁部はスパイクの刃の届かない高さに設けることは前述の植物保護資材と同様である。
図7に示した連結部は、下部枠側面底部から突出する平板の先端に設けた突止具とその背後に設けた下部枠側面から下方に舌状に突出す舌片からなるオス継手と、対応する下部枠側面に設けた孔と当該孔内に存在する前記突止具を契合する孔を設けた平板からなるメス継手からなる。接続部、連結部とも本手段に限らず既存の方法が用いられる。
図8は本植物保護材を連結した状態を示す概念図である。
The connection part of the said plant protection material consists of the female joint provided in the male joint provided in the upper step pressure part lower end of the upper frame, and the lower step pressure part top. The upper frame is not lowered by the beam portion of the upper frame, and is not moved upward because the joint portion engages with each other.
In places where spikes are used, it is the same as the above-mentioned plant protection material that the beam portion connecting the upper treading pressure portion is provided at a height that does not reach the spike blade.
The connecting portion shown in FIG. 7 is a male joint composed of a stopper provided at the tip of a flat plate protruding from the bottom of the lower frame side surface, and a tongue piece protruding downward in a tongue shape from the side of the lower frame provided behind it, It consists of a female joint made of a flat plate provided with a hole provided on the corresponding side face of the lower frame and a hole for engaging the stopper present in the hole. For the connecting part and the connecting part, not only this means but also an existing method is used.
FIG. 8 is a conceptual diagram showing a state in which the plant protective material is connected.
図9は、第3の発明である本植物保護資材の第3の例を示す概念図であり、上部枠と下部枠との関係は同じなため、上部枠のみを示している。図9aは、上部枠を示し、図9bは中間枠を示し、図9cは上部枠と中間枠を接続した状態の断面図である。図に示すように、上部踏圧部は、上部枠と中間枠からなり、中間枠はその格子の交点上に突状部を設け、上部枠の踏圧部内に挿入できるようにしたものである。その結果、踏圧部内部に突状部をその周囲および上部に空間を保ちながら設けられる。踏圧により空気は突状部の側壁に沿って流れ、中間枠の格子間より下方に流れる。
突状部が内部にあることにより、踏圧により踏圧部が下方に押されても内部の突状部に邪魔されそれ以上下がることがない。踏圧部をつなぐ梁部の位置と踏圧部が下がる位置との間の距離が、スパイクなどの刃の長さ以上に保てれば運動中スパイクが上部踏圧部の梁部に引っかかり不測の転倒などによる事故、本植物保護材の上下部枠が分離したりする事故が防止できる。
図10は上記上部枠と中間枠を一体化したものを示している。
また、中間枠を使用せず、本第1ないし第2までの発明に使用した下部枠の踏圧部の頂部に第3の発明で説明した突状部を設け、上部踏圧部内に挿入可能としておくことでも実現できる。
FIG. 9 is a conceptual diagram showing a third example of the present plant protection material according to the third invention. Since the relationship between the upper frame and the lower frame is the same, only the upper frame is shown. 9a shows the upper frame, FIG. 9b shows the intermediate frame, and FIG. 9c is a cross-sectional view of the state in which the upper frame and the intermediate frame are connected. As shown in the figure, the upper stepping pressure portion is composed of an upper frame and an intermediate frame, and the intermediate frame is provided with a protruding portion at the intersection of the lattice so that it can be inserted into the stepping pressure portion of the upper frame. As a result, the projecting portion is provided inside the stepping pressure portion while maintaining a space around and above the pressing portion. By the stepping pressure, air flows along the side wall of the protruding portion and flows downward from between the lattices of the intermediate frame.
Since the protruding portion is inside, even if the stepping pressure portion is pushed downward by the stepping pressure, the protruding portion is not obstructed by the internal protruding portion and does not fall any further. If the distance between the position of the beam part connecting the treading part and the position where the treading part falls is longer than the length of the blade, such as a spike, an accident caused by an unexpected fall, etc., due to the spike being caught in the beam part of the upper treading part Accidents where the upper and lower frames of the plant protection material are separated can be prevented.
FIG. 10 shows the integrated upper frame and intermediate frame.
Further, without using the intermediate frame, the protrusion described in the third invention is provided at the top of the stepping pressure portion of the lower frame used in the first to second inventions so that it can be inserted into the upper stepping pressure portion. Can also be realized.
本第4の発明は、前記本第3の発明で説明した上部枠をそのまま植物保護資材として使用するものである。人の踏圧を対象とする植物保護資材では上部枠のみで十分踏圧を支えることが可能であり、踏圧に対する反力も軽減される。上部枠を単独で植物保護資材とする場合、上部枠相互を接続するための連結手段を設けておくことが好ましい。 In the fourth invention, the upper frame described in the third invention is used as it is as a plant protection material. With plant protection materials that target human treading pressure, it is possible to sufficiently support treading pressure only with the upper frame, and the reaction force against treading pressure is also reduced. When the upper frame is used alone as a plant protection material, it is preferable to provide a connecting means for connecting the upper frames to each other.
本植物保護資材の材質は、下部枠はコンクリート製品あるいは射出成形可能なポリオレフィンなどで製造され上部枠は人の踏圧を軽減するため射出成形可能なポリオレフィンなどで製造される。
本発明3に示す植物保護資材では、上部枠の材質は、踏圧により空気を供給するためゴムなどを含むエラストマー製が好ましい。
As for the material of the plant protection material, the lower frame is made of a concrete product or an injection-moldable polyolefin, and the upper frame is made of an injection-moldable polyolefin to reduce human treading pressure.
In the plant protection material shown in the third aspect of the present invention, the material of the upper frame is preferably made of an elastomer containing rubber or the like in order to supply air by stepping pressure.
本植物保護資材の使用方法は、路盤上に下部枠を連結敷き設し、土壌を下部透水部に充填し、転圧し、芝生をほぐして撒き上部枠を接続して、図11に示すような状態となるよう芝の生長を待つ、あるいは転圧後、上部枠を接続し、上部枠の頂部まで土壌と芝の種を混合して充填し芝の成長を待つなど適宜実施することができる。 As shown in FIG. 11, the plant protection material is used by connecting and laying a lower frame on a roadbed, filling soil into the lower water-permeable portion, rolling, loosening the lawn and connecting the upper frame. Waiting for the growth of turf to be in a state, or after rolling, connecting the upper frame, mixing the soil and turf seeds up to the top of the upper frame and waiting for the growth of the turf, etc.
