Description
本発明は、複数の枠を係合して使用する芝生保護材の係合技術に属する。 The present invention belongs to a lawn protection material engagement technique in which a plurality of frames are engaged and used.
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踏圧部と透孔部からなる図7aに示すような芝生保護材(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7b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。
更に特開2008-35856には3層構造の枠を組み合わせてより一層踏み圧の軽減を図る提案がなされている。
下部枠と上部枠からなる植物保護材の係合方法は、図8aに示す格子状の交点を輪とし、輪の上方に設けた縁片を有する上部枠及び図8bに示す格子状の交点に立設する棒の上端に笠片を有する下部枠とし、係合時縁片上で開いた笠片により係合するものである。しかし、一度係合が外れた場合人の踏み圧により再び係合される方法が求められている。
There are golf courses, playgrounds, parks, gardens, factory roadsides, and various site spaces as open spaces where grass and other plants have been nurtured. there were. Recently, a lawn protective material as shown in FIG. 7a comprising a treading pressure part and a through-hole part to protect the plant from the treading pressure of a person entering the lawn or the 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 as shown in FIG.
Furthermore, Japanese Patent Application Laid-Open No. 2008-35856 proposes further reducing the stepping pressure by combining a three-layer frame.
The method of engaging the plant protection material composed of the lower frame and the upper frame is based on the lattice-shaped intersection shown in FIG. The lower frame is provided with a cap piece at the upper end of the erected rod, and is engaged by the cap piece opened on the edge piece when engaged. However, there is a need for a method of re-engaging with a person's stepping pressure once the engagement is disengaged.
本発明は、上部枠と下部枠からなる芝生保護材で係合が外れた場合再度踏み圧により再係合する係合手段の提案である。 The present invention is a proposal of an engagement means that re-engages with a stepping pressure when the engagement is released by a lawn protective material composed of an upper frame and a lower frame.
本発明は、基盤上に敷設される下部枠と下部枠上に係合される上部枠からなる芝生保護材にあって、下部枠と上部枠は共に網目状とされ、互いに上下に係合されるときその網目の交点が一致し、下部枠の交点には上方に突出する棒が設けられ、その上端部に笠片が設けられ、上枠部の交点は輪とされ、当該輪の周囲には上方に立ち上がる筒部が設けられ、当該筒部の中間から筒内壁から筒中心に向かう縁片が設けられ、前記笠片が前記輪に挿入され、縁片上で広がることで下部枠と上部枠が係合した芝生保護材である。
上下枠の係合部分が外れた場合踏み圧で再係合されるよう、係合部の上部に踏み圧により縁片が下方に下がるよう縁片が設けられる筒部を更に上方に延ばした。
The present invention is a lawn protective material comprising a lower frame laid on a base and an upper frame engaged on the lower frame, and both the lower frame and the upper frame are meshed and are engaged with each other vertically. At the intersection of the lower frame is provided with a bar protruding upward, a cap piece is provided at the upper end, and the intersection of the upper frame is a ring, around the ring Is provided with a cylindrical portion that rises upward, an edge piece is provided from the middle of the cylindrical portion toward the center of the cylinder from the middle of the cylinder portion, the cap piece is inserted into the ring, and spreads on the edge piece, thereby lower frame and upper frame Is a lawn protective material engaged.
In order to re-engage with the stepping pressure when the engaging part of the upper and lower frames is disengaged, the cylinder part provided with the edge piece is further extended upward so that the edge piece is lowered downward by the stepping pressure on the upper part of the engaging part.
本発明は、(1)上部枠と下部枠の係合部分を形成する上部枠に設けた縁片と下部枠に設けた笠片が係合状態にある時、縁片を設ける筒部を更に上方に伸ばしたため、その筒部の上部を踏むことで筒部の中間部に設けた縁片が下方に下がり、外れた笠片が再び縁片の上方にくるため係合が再現される。 In the present invention, (1) when the edge piece provided on the upper frame forming the engaging portion of the upper frame and the lower frame and the cap piece provided on the lower frame are in the engaged state, Since the upper part of the cylinder part is stepped on, the edge piece provided at the intermediate part of the cylinder part is lowered downward, and the detached cap piece comes again above the edge piece to reproduce the engagement.

FIG. 4b shows a state in which the cylinder portion is bent by the stepping pressure, the edge portion of the cylinder portion moves outward, and the cap piece of the lower frame recovers the degree of freedom and moves above the edge piece. While repeating such a state, the cap piece moves above the edge piece and the engagement is reproduced.
以下本植物保護材の使用例を記述する。
本上部枠と下部枠の2層構造での使用例を図5に示す。
本使用例では従来の踏み圧部と透水部を有する植物保護材と同様、格子部が踏み圧部として機能し、格子の目に当たる部分が透水部として機能する。従い芝等の植物は透水部から延伸し、新芽に掛かる踏み圧は踏み圧部で支えられるため直接掛かることがない。
Examples of use of this plant protection material are described below.
An example of use in a two-layer structure of the upper frame and the lower frame is shown in FIG.
In this usage example, the lattice portion functions as a foot pressure portion and the portion of the lattice that corresponds to the eyes functions as the water permeable portion, as in the case of a conventional plant protection material having a foot pressure portion and a water permeable portion. Therefore, plants such as turf extend from the water-permeable part, and the treading pressure applied to the shoots is supported directly by the treading pressure part, so it is not directly applied.
図6は、より強い踏み圧を受ける場合の使用例である。最下層部に戴円錐形の頂部を踏み圧部とし、その下部で係合し、踏み圧部で囲まれた場所を透水部とする図7aに示す従来の基礎枠が用いられる。この場合下部枠の下及び基礎枠の踏み圧部頂部に互いに係合する係合具が用いられる。
いずれの使用例においても踏み圧部が人あるいは車の踏み圧を受け、透水部が土壌を充填し芝等の植物を育成させると共に雨水等が地中に浸透する場所となることは同様である。
FIG. 6 shows an example of use when receiving a stronger pedal pressure. A conventional basic frame shown in FIG. 7a is used in which the top of the cone shape is the bottom pressure part at the lowermost layer part, the bottom part is engaged, and the place surrounded by the step pressure part is the water permeable part. In this case, an engaging tool that engages with each other under the lower frame and the top of the foot pressure portion of the base frame is used.
In any use example, it is the same that the treading pressure part receives the treading pressure of a person or a car, and the water permeable part fills the soil and grows plants such as turf and rainwater penetrates into the ground. .
本芝生保護材の材質は、基礎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る。下部枠と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。上部枠と下部枠の透水部の少なくとも一部は雨水等が地中に浸透可能となるよう、上下に連通するように配列することが好ましい。上部枠の材質は、踏圧により筒部が撓む必要があ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 lawn protective material, the base frame is manufactured from a concrete product or an injection moldable polyolefin. The lower and upper frames are made of injection-mouldable polyolefin to reduce human treading pressure. It is preferable that at least a part of the water permeable portions of the upper frame and the lower frame are arranged so as to communicate vertically with each other so that rainwater can penetrate into the ground. The material of the upper frame is preferably made of an elastomer containing rubber or the like because the cylindrical portion needs to be bent by a stepping pressure.
