芝生やその他の植物を育成させた広場として、ゴルフ場、運動場、公園、庭園、工場の路側、各種の敷地空間内があり、古くは芝生保護のため芝生内は立ち入り禁止とする場合が普通であった。最近では芝生内に立入る人の、あるいは車の踏圧から植物を保護するための図８ａに示すような踏圧部と透孔部からなる芝生保護材（特開平2-145137、特開平4-75541）が各種提案され使用されている。
さらにこれら芝生保護材を用いた際に人の踏圧を和らげるため、芝生保護材上に更に平坦な上部枠を設置し、人の足と上部枠との接触部の面積を大きくし踏圧部からの反力を軽減する図８ｂに示すような芝生保護材が特開平5-56724に開示されている。
芝生の保護は芝生保護材による保護以外に、施肥、日当たり、風の通り、水遣りなど通常の芝生保護のための手入れが必要であり、特開平2008-35856 にはエラストマー製の上端が閉鎖された筒状の踏み圧部を有する上部枠を使用し、踏み圧により踏み圧部内の空気を供給する手段を本発明者らが開示した。
上部枠の両面を使用することで、一つは空気を供給し、運動靴などで濡れた上部枠面を歩く際、滑らないようにする手段の使い分けが求められている。 There are golf courses, playgrounds, parks, gardens, factory roadsides, and various site spaces as open spaces where lawns and other plants were nurtured. there were. Recently, a lawn protective material composed of a treading pressure part and a through hole as shown in FIG. 8a for protecting a plant from the treading pressure of a person entering the lawn or a car (JP-A-2-145137, JP-A-4-75541). ) Have been proposed and used.
Furthermore, in order to relieve human treading pressure when these lawn protective materials are used, a flat upper frame is installed on the lawn protective material to increase the area of contact between the human foot and the upper frame, Japanese Patent Laid-Open No. 5-56724 discloses a lawn protective material for reducing reaction force as shown in FIG.
Lawn protection requires protection for normal lawn protection, such as fertilization, sunlight, wind, watering, etc., as well as protection by lawn protection material. The present inventors have disclosed means for supplying air in the stepping pressure portion by means of the stepping pressure using an upper frame having a cylindrical stepping pressure portion.
By using both sides of the upper frame, one is required to use different means to supply air and prevent slipping when walking on the wet upper frame surface with athletic shoes.

以下本発明を図により詳細に説明する。
図１は、本第1の発明を構成する芝生保護材を構成する下部枠の例を示す概念図である。
図１ａは、平面図、図１ｂはA-A’線における断面図である。図に示すように下部枠は基礎面から立ち上がる戴円錐形の筒部を連結したものであり、相接する2辺に雄継ぎ手、他の2辺に雌継ぎ手が設けられ、互いに左右に連結可能とされている。筒部が下部踏み圧部を形成し、筒部頂部が人あるいは車からの荷重を受ける部分であり、下部踏み圧部で囲まれた空間が下部透水部を形成し、土壌が充填され芝生等が生育する領域であると共に雨水等が地下に浸透していく領域でもある。下部踏み圧部は本図の構成を有するもの以外に、矩形あるいは多角形の各筒を連結したハニカム形状のものであってもよい。この場合、壁面が踏み圧部に該当し、角筒の内部が透水部に該当する。 Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing an example of a lower frame constituting the lawn protective material constituting the first invention.
FIG. 1A is a plan view, and FIG. 1B is a cross-sectional view taken along the line AA ′. As shown in the figure, the lower frame is a conical cylinder that rises from the base surface, and has a male joint on the two adjacent sides and a female joint on the other two sides. It is said that. The cylinder part forms the lower treading pressure part, the top part of the cylinder part receives the load from the person or the car, and the space surrounded by the lower treading pressure part forms the lower water permeable part, filled with soil, lawn etc. It is a region where rainwater etc. penetrates underground. The lower treading pressure portion may have a honeycomb shape in which rectangular or polygonal tubes are connected in addition to the configuration shown in this figure. In this case, the wall surface corresponds to the stepping pressure portion, and the inside of the square tube corresponds to the water permeable portion.

下部踏み圧部の頂部には十字の溝が切られ、後述する上部枠の網目の交点がその溝にはめ込まれ契合できるようになっている。 A cross-shaped groove is cut at the top of the lower stepping pressure portion, and an intersection of a mesh of an upper frame described later is fitted into the groove so that engagement can be made.

上部枠は網目状であり、図では格子状とされている。表面の格子には棒状の突起が設けられている。裏面には格子の交点を中心とする十字状の突起物が設けられ各格子に沿って低くなる滑り止めを形成している。上部枠には下部枠と異なり、上部枠同士を連結するための連結具は設けられていない。下部枠同士を連結した後、上部枠を下部枠上に契合し、上部枠同士を互いに連結すると広い面積に配設した場合、歪が蓄積し上部枠同士の連結が困難となる場合がありその不都合を避けるためである。 The upper frame has a mesh shape, and is a lattice shape in the figure. Bar-shaped protrusions are provided on the surface lattice. On the back surface, a cross-shaped protrusion centering on the intersection of the lattices is provided to form a slip stopper that is lowered along each lattice. Unlike the lower frame, the upper frame is not provided with a connector for connecting the upper frames. After connecting the lower frames, if the upper frame is engaged on the lower frame and the upper frames are connected to each other, if they are arranged in a large area, distortion may accumulate and it may be difficult to connect the upper frames. This is to avoid inconvenience.

図３は、本第１の発明を構成する芝生保護材を構成する第2の上部枠の例を示す概念図である。素材はエラストマーなどの柔らかい弾性に富んだ部材で成形することが好ましい。図に示すように、上端部が閉鎖し、下端が開放された筒状部を連結したものである。図２ａに示す上部枠の表面に設けられた棒状の突起物に、筒状部が突起物と筒状部の内壁面との間に隙間を設けて挿入される。人の踏み圧により筒状部がつぶれ、筒状部開放端から内部の空気を放出する。 FIG. 3 is a conceptual diagram showing an example of a second upper frame constituting the lawn protective material constituting the first invention.
