Description

【０００１】
【発明の属する技術分野】
本発明は、人工芝生の接続構造およびその接続方法に関するものである。
【０００２】
【従来の技術】
一般に、人工芝生製グラウンドは、アスファルトやコンクリートなどの下地層に直接もしくはクッション層を介して人工芝生を敷設したもので、多くの屋内外施設に採用されている。ここで、人工芝生は、ポリエステルやポリプロピレンなどの合成樹脂製基布にナイロンやポリプロピレンなどの合成樹脂製パイル糸を設定長さになるように植設して芝葉を形成したものであり、製造設備上の制約から一定幅以上に製造することはできない。したがって、広大な人工芝生製グラウンドを形成する場合は、一定幅の長尺状の人工芝生を設定数枚幅方向に順に敷設する必要がある。
【０００３】
この際、グラウンド面に人工芝生を単に敷設しただけでは負荷が作用すると人工芝生が移動するため、複数枚の人工芝生を接続して大きな幅の本体人工芝生を形成し、この本体人工芝生によってグラウンド面を覆うようにしている。例えば、実公昭５９−３１７６３号公報に記載されるように、面ファスナーを介して隣接する一対の人工芝生を接続したり、実公平１−４４５６２号公報に記載されるように、溶着フィルムを熱溶着させて接合布によって隣接する一対の人工芝生を接続したり、実開昭６０−９６４０３号公報の従来技術欄に記載されるように、隣接する一対の人工芝生の側端縁を縫製して接続するようにしている。
【０００４】
【発明が解決しようとする課題】
しかしながら、人工芝生を面ファスナーで接続する方式では、接続部の隙間や部分的な剥離によって段付きが発生し易いという問題がある。また、溶着フィルムを熱溶着させて接合布で人工芝生を接続する方式では、溶着フィルムを加熱して溶融させる必要があることから、作業者の熟練度や作業環境などの条件によっては接続強度を確保できない場合があり、信頼性が低いという問題がある。一方、人工芝生の側端縁を縫製する方式では、負荷が作用すると、縫製糸が合成樹脂製基布の織り組織を引っ張ることから、合成樹脂製基布の織り組織が乱れて接続部に隙間が出やすいという問題がある。
【０００５】
本発明は、このような問題点に鑑みてなされたもので、人工芝生の側端縁を縫製して接続する方式において、人工芝生の接続部分の強度を確保して接続部の隙間の発生を防止することのできる人工芝生の接続構造を提供するものである。
【０００６】
また、本発明は、人工芝生の接続部分の強度を確保しつつ簡単かつ短時間に接続して本体人工芝生を形成することのできる人工芝生の接続方法を提供するものである。
【０００７】
【課題を解決するための手段】
本発明のうち請求項１記載の発明は、合成樹脂製基布に合成樹脂製パイル糸を設定長さになるように植設して芝葉を形成するとともに、合成樹脂製基布の裏面にアンダーパッドを貼着してなる長尺状の人工芝生が幅方向に複数枚接続された本体人工芝生において、各人工芝生のアンダーパッドの裏面側側端縁部に補強テープが接着され、隣接する一対の人工芝生の側端縁が補強テープを通して縫製されていることを特徴とするものである。

【００１４】
【発明の実施の形態】
以下、本発明の実施例の形態を図面に基づいて説明する。
図１には、本発明の人工芝生の接続構造の第１実施形態が示されており、各人工芝生１は、ポリエステルやポリプロピレンなどの合成樹脂製基布１１にナイロンやポリプロピレンなどの合成樹脂製パイル糸を設定長さになるように植設して芝葉１２を形成するとともに、合成樹脂製基布１１の裏面にクッション層としてのアンダーパッド１３を熱融着して構成されている。そして、複数枚の長尺状の人工芝生１の側端縁を縫製して接続することにより、設定幅の本体人工芝生１０が形成されるものである。
【００１５】
ところで、各人工芝生１のアンダーパッド１３の裏面側側端縁部には、補強テープＴが接着剤を介して接着されており、この補強テープＴを通して隣接する人工芝生１，１の側端縁が縫製糸Ｓによって縫製されていることから、補強テープＴ自身が縫製糸Ｓを支持することができ、接続強度を確保することが可能となる。したがって、人工芝生１，１の縫製接続部分に負荷が作用しても、その負荷を確実に支持することが可能となり、合成樹脂製基布１１の側端縁部の織り組織を乱して接続部に隙間を発生させることを確実に防止することができる。
【００１６】
ここで、接着剤は、競技時の違和感や縫製の作業性を考慮すると、ウレタン系接着剤やゴム系接着剤などの可撓性接着剤が望ましい。
次に、前述した本体人工芝生１０を形成する場合について説明すると、まず、必要な長さに切断された長尺状の人工芝生１を設定幅となるように複数枚グラウンドに運び込み、それらの人工芝生１をアンダーパッド１３が上となるように幅方向に並設する。
【００１７】
ここで、複数枚幅方向に並設された人工芝生１のうち、中央に位置する人工芝生１を符号１ａで表記し、中央の人工芝生１ａの左側に並設された人工芝生１を符号１ｂで表記し、中央の人工芝生１ａの右側に並設された人工芝生１を符号１ｃで表記し、以下、人工芝生１ａの左側に順に並設された人工芝生１を符号１ｄ，１ｆ…と表記し、また、人工芝生１ｃの右側に順に並設された人工芝生１を符号１ｅ，１ｇ…と表記するものとする（図２参照）。
【００１８】
次いで、各人工芝生１のアンダーパッド１３の裏面側左右両側端縁部（最外側に位置する人工芝生１については左右内方の側端縁部）に接着剤を塗布し、補強テープＴを接着する（図３参照）。各人工芝生１のアンダーパッド１３の裏面側側端縁部に補強テープＴが接着されたならば、中央の人工芝生１ａをその芝葉１２が上となるように反転させる（図４参照）。そして、反転させた中央の人工芝生１ａの左側に並設された人工芝生１ｂを裏向きのまま中央の人工芝生１ａの上に引き上げ、それらの人工芝生１ａ，１ｂの側端縁を合わせた後（図５参照）、それらの人工芝生１ａ，１ｂの側端縁をミシンを用いて縫製する（図６参照）。人工芝生１ａ，１ｂの側端縁の縫製が終了すれば、人工芝生１ｂをその縫製部を中心に折り返すことにより、中央の人工芝生１ａとその左側に並設された人工芝生１ｂとをそれらの芝葉１２，１２を上にして接続することができる（図７参照）。
【００１９】
次に、中央の人工芝生１ａの右側に並設された人工芝生１ｃを中央の人工芝生１ａの上に裏向きのまま引き上げ（図８参照）、前述した人工芝生１ｂと同様に、それらの人工芝生１ａ，１ｃの側端縁をミシンで縫製し、人工芝生１ｃをその縫製部を中心として折り返すことにより、中央の人工芝生１ａとその右側に並設された人工芝生１ｃをそれらの芝葉１２，１２を上にして接続することができる。
【００２０】
この後、先に縫製した人工芝生１ｂの左側に並設された人工芝生１ｄを同様に作業して人工芝生１ｂに縫製接続し、次いで、先に縫製した人工芝生１ｃの右側に並設された人工芝生１ｅを同様に作業して人工芝生１ｃに縫製接続し、以下、先に縫製された人工芝生１に隣接する人工芝生１を左右交互に縫製接続し、設定幅となるまで必要枚数接続して本体人工芝生１０を形成する。
【００２１】
このように、複数枚の人工芝生１を左右交互に縫製して接続することにより、左右一方の人工芝生１を縫製する間に左右他方の人工芝生１を縫製するための準備作業に費やすことが可能となり、簡単かつ短時間に接続して本体人工芝生１０を形成することができる。
【００２２】
このようにしてグラウンド面に本体人工芝生１０を敷設して人工芝生製グラウンドを形成することができ、各種競技を行うことができる。
ところで、人工芝生製グラウンドを多目的に活用するためには、本体人工芝生１０をそのまま巻き取って撤去し、あるいは、繰り出して敷設する必要がある。この場合、本体人工芝生１０の重量は大きなものとなり、その巻き取りおよび繰り出しには機械力を利用しなければならないが、その際、本体人工芝生１０には、その重量による大きな引っ張り力が作用する。そして、本体人工芝生１０をロール状に巻き取ると、人工芝生１のアンダーパッド１３を縫製糸Ｓによって縫製していることから、ロール状の人工芝生１の外周面部分および内周面部分において人工芝生１の厚みによる内外径差によって縫製糸Ｓに作用する張力に差が生じ、その結果、人工芝生１，１の接続部にうねり状のしわが発生することがある。このようなしわが発生すると、競技に支障が生じることになる。
【００２３】
したがって、前述した本体人工芝生１０においては、グラウンドに本体人工芝生１０を常設する人工芝生製グラウンドの場合は問題はないが、グラウンドを多目的に活用するため、必要に応じて本体人工芝生１０を巻き取り、あるいは、繰り出して使用する人工芝生製グラウンドには採用することができない。
【００２４】
このような点を踏まえて、本発明の人工芝生の接続構造の第２実施形態においては、競技時に人工芝生１に負荷が作用してもその負荷を確実に支持して人工芝生１，１の接続部に隙間を発生させることがなく、かつ、機械力を利用して巻き取った場合、その接続部にしわを発生させることがない接続構造を提供するものである。
【００２５】
図９には、本発明の人工芝生の接続構造の第２実施形態が示されており、長尺状の人工芝生１を幅方向に複数枚接続して本体人工芝生１０Ａを形成している。ここで、各人工芝生１は、前述した実施形態と同様に、合成樹脂製基布１１に芝葉１２を形成するとともに、合成樹脂製基布１１の裏面にアンダーパッド１３を熱融着して構成されている。
【００２６】
そして、各人工芝生１の合成樹脂製基布１１の裏面側側端縁部には、補強テープＴが接着剤を介して接着されており、この補強テープＴを通して隣接する人工芝生１，１の合成樹脂製基布１１，１１の側端縁が縫製糸Ｓによって縫製されていることから、補強テープＴ自身が縫製糸Ｓを支持することができるとともに、硬化した接着剤が合成樹脂製基布１１の側端縁部の織り組織を補強することができ、大きな接続強度を確保することが可能となる。したがって、人工芝生１，１の縫製接続部分に負荷が作用しても、その負荷を確実に支持することが可能となり、人工芝生１の合成樹脂製基布１１の側端縁部の織り組織を乱して隙間を発生させることことを確実に防止することができる。
【００２７】
また、本体人工芝生１０Ａを機械力を利用して巻き取り、あるいは、繰り出した場合、アンダーパッド１３の厚みに比較してはるかに厚みの薄い合成樹脂製基布１１の側端縁を補強テープＴを通して縫製していることから、縫製部の内外径差は発生せず、しわの発生を確実に防止することができる。
【００２８】
ところで、各人工芝生１の合成樹脂製基布１１の裏面側側端縁部に補強テープＴを接着する際、その作業に先立って各人工芝生１，１のアンダーパッド１３の側端縁部が一定幅にわたって剥離されている。そして、隣接する一対の人工芝生１，１の合成樹脂製基布１１，１１の側端縁を縫製した後、隣接する一対の人工芝生１，１の合成樹脂製基布１１，１１のアンダーパッド１３が剥離された裏面側側端縁部に接着剤を介してアンダーパッド１３１が接着されている。
【００２９】
なお、接着剤は、競技時の違和感や縫製の作業性とともに、本体人工芝生１０Ａの巻き取り時の曲げ作用を考慮して、第１実施形態の場合と同様に可撓性接着剤が好ましい。
【００３０】
次に、本体人工芝生１０Ａを形成する場合について説明すると、第１実施形態の場合と同様に、必要な長さに切断された長尺状の人工芝生１を設定幅となるように複数枚運び込み、それらの人工芝生１をアンダーパッド１３が上となるように幅方向に並設する。
【００３１】
ここで、各人工芝生１に付す符号は、図２において各人工芝生１に付した符号と同一の符号を用いるものとする。
人工芝生１の運び込みが終了すれば、各人工芝生１のアンダーパッド１３の左右両側端縁部（最外側に位置する人工芝生１については左右内方の側端縁部）を一定幅にわたって剥離させた後（図１０参照）、アンダーパッド１３が剥離された合成樹脂製基布１１の裏面側側端縁部に接着剤を塗布し、補強テープＴを接着する（図１１参照）。
【００３２】
各人工芝生１の合成樹脂製基布１１の裏面側側端縁部に補強テープＴが接着されたならば、中央の人工芝生１ａをその芝葉１２が上となるように反転させる（図４参照）。そして、反転させた中央の人工芝生１ａの左側に並設された人工芝生１ｂを裏向きのまま中央の人工芝生１ａの上に引き上げ、それらの人工芝生１ａ，１ｂの側端縁を合わせた後（図５参照）、それらの人工芝生１ａ，１ｂの合成樹脂製基布１１，１１の側端縁をミシンを用いて縫製する（図１２参照）。人工芝生１ａ，１ｂの側端縁の縫製が終了すれば、人工芝生１ｂをさらに中央の人工芝生１ａ方向にずらし、両人工芝生１ａ，１ｂの合成樹脂製基布１１，１１の縫製された側端縁部を平坦な位置に横移動させる（図１３参照）。この後、両人工芝生１ａ，１ｂの合成樹脂製基布１１，１１の縫製部を含む裏面側側端縁部に接着剤を塗布し、先に人工芝生１ａ，１ｂから剥離されたアンダーパッドを埋めるように、アンダーパッド１３１を接着する（図１４参照）。次いで、人工芝生１ｂをその縫製部を中心に折り返すことにより、中央の人工芝生１ａとその左側に並設された人工芝生１ｂとをそれらの芝葉１２，１２を上にして接続することができる（図７参照）。
【００３３】
次に、中央の人工芝生１ａの右側に並設された人工芝生１ｃを中央の人工芝生１ａの上に裏向きのまま引き上げ（図８参照）、前述した人工芝生１ｂと同様に、それらの人工芝生１ａ，１ｃの側端縁をミシンで縫製し、両人工芝生１ａ，１ｃの合成樹脂製基布１１，１１の裏面側側端縁部に接着剤を介してアンダーパッド１３１を接着した後、人工芝生１ｃをその縫製部を中心として折り返すことにより、中央の人工芝生１ａとその右側に並設された人工芝生１ｃをそれらの芝葉１２，１２を上にして接続することができる。
【００３４】
この後、同様に作業することにより、先に縫製された人工芝生１ｂの左側に並設された人工芝生１ｄを人工芝生１ｂに縫製接続し、次いで、先に縫製した人工芝生１ｃの右側に並設された人工芝生１ｅを人工芝生１ｃに縫製接続し、以下、先に縫製された人工芝生１に隣接する人工芝生１を左右交互に縫製して接続し、設定幅となるまで必要枚数接続して本体人工芝生１０Ａを形成する。
【００３５】
この実施形態においても、左右一方の人工芝生１を縫製する間に左右他方の人工芝生１を縫製するための準備作業に費やすことが可能となり、簡単かつ短時間に接続して本体人工芝生１０Ａを形成することができるものである。
【００３６】
このようにして形成された本体人工芝生１０Ａは、その前後両端に導布２１にアンダーパッド２２を接着して形成された巻き取り側の主軸導布２および導布３１にアンダーパッド３２を接着するとともに導布３１に先端金具３３を巻回して固定された引き出し側の先端金具導布３の一端がそれぞれ接着された後（図１５および図１６参照）、詳細には図示しないが、ピット内に収容された巻き取り装置に前述した主軸導布２の他端を連結すればよい。
【００３７】
そして、図示しない巻き取り装置を駆動すれば、巻き取り側の主軸導布２から巻き取りが開始され、最終的に本体人工芝生１０Ａが巻き取られる。一方、本体人工芝生１０Ａを敷設する場合は、先端金具導布３の他端にワイヤーを連結し、図示しない巻き取り装置を介してワイヤーを巻き取ることにより、本体人工芝生１０Ａをピット内から引き出して敷設することができる。
【００３８】
このように、各人工芝生１を分離することなく接続された本体人工芝生１０Ａを一体に巻き取り、あるいは、繰り出すことにより、本体人工芝生をファスナーなど分離可能に接続した人工芝生によって形成し、本体人工芝生を構成する各人工芝生毎に巻き取り、あるいは、繰り出す方式に比較して巻き取りや繰り出しに要する作業時間を大幅に減少させることができる。
【００３９】
具体的実施例としては、ポリエステル織布製基布に高さ１４ｍｍのナイロン製芝葉を植設するとともに、基布の裏面に厚さ１０ｍｍのポリエチレンフォーム製アンダーパッドを貼着してなる幅３．６ｍ、長さ８０ｍの人工芝生を１７枚用意し、これらの人工芝生の基布の裏面側側端縁部を、ポリエステル基布の表面に塩化ビニルを被覆してなる補強テープで補強し、隣接する一対の人工芝生をポリエステル製縫製糸で縫製して縦８０ｍ、横６０ｍの本体人工芝生を形成した。
【００４０】
なお、前述した実施形態においては、人工芝生１の合成樹脂製基布１１の裏面側側端縁部に接着剤を介して補強テープＴを接着して例示したが、図１７に示すように、５ｍｍ未満、好ましくは３ｍｍ以下の厚みを残して剥離されたアンダーパッド１３に補強テープＴを接着して縫製し、本体人工芝生１０Ｂを形成するようにしてもよい。すなわち、アンダーパッド１３の厚みが５ｍｍを越えた状態で縫製すると、前述したように、本体人工芝生１０Ｂの巻き取り時、アンダーパッド１３の厚みによる内外径差によって縫製糸Ｓに作用する張力が不均一となり、しわの発生を招来するおそれがあるからである。このように、アンダーパッド１３を一部残して剥離する方式は、アンダーパッド１３が剥離可能な複数枚の積層構造である場合に適用することができる。
【００４１】
また、両人工芝生１，１の残されたアンダーパッド１３の裏面側側端縁部には、接着剤を介してアンダーパッド１３２が接着されるものである。
さらに、図１８に示すように、アンダーパッド１３を用いない人工芝生１の場合は、その合成樹脂性基布１１の裏面に直接補強テープＴを接着した後、同様に隣接する一対の人工芝生１，１を順に縫製して本体人工芝生１０Ｃを形成すればよい。
【００４２】
図１７および図１８に示した実施形態においても、人工芝生１，１の縫製接続部分に作用する負荷を確実に支持することができ、人工芝生１の合成樹脂製基布１１の側端縁部の織り組織を乱して隙間を発生させることを確実に防止することができる他、本体人工芝生１０Ｂ，１０Ｃを機械力を利用して巻き取り、あるいは、繰り出した場合、縫製部分の内外径差は発生せず、しわの発生を確実に防止することができるものである。
【００４３】
【発明の効果】
以上のように本発明の請求項１記載の人工芝生の接続構造によれば、隣接する一対の人工芝生の接続部分の強度を確保することができ、縫製接続部分に負荷が作用しても、人工芝生の合成樹脂製基布の側端縁部の織り組織を乱すことはなく、接続部の隙間の発生を確実に防止することができる。
【００４４】
また、本発明の請求項２および請求項３記載の人工芝生の接続構造によれば、隣接する一対の人工芝生の接続部分の強度を確保することができ、縫製接続部分に負荷が作用しても、人工芝生の合成樹脂製基布の側端縁部の織り組織を乱すことはなく、接続部の隙間の発生を確実に防止することができる。また、本体人工芝生を機械力を利用して巻き取り、繰り出した場合においても、接続部にしわを発生させることはない。
【００４５】
一方、本発明の請求項５記載の人工芝生の接続方法によれば、隣接する一対の人工芝生の接続部分の強度を確保した本体人工芝生を簡単かつ短時間に形成することができる。
【００４６】
また、本発明の請求項６、請求項７および請求項８記載の人工芝生の接続方法によれば、隣接する一対の人工芝生の接続部分の強度を確保するとともに、機械力を利用して巻き取っても接続部にしわを発生させることのない本体人工芝生を簡単かつ短時間に形成することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an artificial grass connection structure and a connection method thereof.
[0002]
[Prior art]
Generally, an artificial grass ground is one in which artificial grass is laid directly on a base layer such as asphalt or concrete or via a cushion layer, and is used in many indoor and outdoor facilities. Here, the artificial turf is a turf leaf formed by implanting a synthetic resin pile yarn such as nylon or polypropylene to a set length on a synthetic resin base cloth such as polyester or polypropylene. It cannot be manufactured beyond a certain width due to equipment restrictions. Therefore, when forming a vast artificial grass lawn, it is necessary to lay a predetermined number of long artificial grasses in the width direction in order.
[0003]
At this time, simply laying the artificial lawn on the ground surface causes the artificial lawn to move when a load acts, so a plurality of artificial lawns are connected to form a large width main body artificial lawn, and this main body artificial lawn It covers the surface. For example, as described in Japanese Utility Model Publication No. 59-31763, a pair of adjacent artificial grasses are connected via a hook-and-loop fastener, or as described in Japanese Utility Model Publication No. A pair of adjacent artificial grasses are connected by welding and joined together, or side edges of a pair of adjacent artificial grasses are sewn as described in the prior art section of Japanese Utility Model Publication No. 60-96403. I try to connect.
[0004]
[Problems to be solved by the invention]
However, the method of connecting artificial grass with a hook-and-loop fastener has a problem that a step easily occurs due to a gap or a partial peeling of a connecting portion. Also, in the method of connecting the artificial grass with a bonding cloth by heat-welding the welding film, it is necessary to heat and melt the welding film. In some cases, it cannot be secured, and there is a problem that reliability is low. On the other hand, in the method of sewing the side edge of the artificial grass, when a load is applied, the sewing thread pulls the woven structure of the synthetic resin base cloth, so that the woven structure of the synthetic resin base cloth is disturbed and a gap is formed in the connection portion. There is a problem that is easy to come out.
[0005]
The present invention has been made in view of such a problem, and in a method in which side edges of an artificial grass are sewn and connected, the strength of a connection portion of the artificial grass is ensured and generation of a gap in a connection portion is prevented. It is intended to provide an artificial grass connection structure that can be prevented.
[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a first embodiment of the artificial turf connection structure of the present invention. Each artificial turf 1 is made of a synthetic resin base cloth 11 such as polyester or polypropylene and a synthetic resin base cloth 11 such as nylon or polypropylene. Pile yarns are planted so as to have a set length to form turf leaves 12, and an under pad 13 as a cushion layer is thermally fused to the back surface of the synthetic resin base cloth 11. Then, the main artificial grass 10 having a set width is formed by sewing and connecting the side edges of the plurality of long artificial grasses 1.
[0015]
By the way, a reinforcing tape T is adhered to the back side edge of the under pad 13 of each artificial turf 1 via an adhesive, and the side edge of the adjacent artificial turf 1, 1 is inserted through the reinforcing tape T. Is sewn with the sewing thread S, the reinforcing tape T itself can support the sewing thread S, and the connection strength can be secured. Therefore, even if a load acts on the sewing connection portion of the artificial turf 1, 1, the load can be reliably supported, and the woven structure of the side edge of the synthetic resin base cloth 11 is disturbed and the connection is performed. It is possible to reliably prevent a gap from being generated in the portion.
[0016]
Here, the adhesive is desirably a flexible adhesive such as a urethane-based adhesive or a rubber-based adhesive in consideration of a sense of discomfort during a game or workability in sewing.
Next, a description will be given of a case of forming the main body artificial grass 10 described above. First, a plurality of long artificial grasses 1 cut to a required length are carried to the ground so as to have a set width, and the artificial grasses 10 are formed. The lawns 1 are arranged side by side in the width direction such that the underpad 13 is on top.
[0017]
Here, of the plurality of artificial grasses 1 arranged side by side in the width direction, the artificial grass 1 located at the center is denoted by reference numeral 1a, and the artificial grass 1 arranged side by side on the left side of the artificial grass 1a at the center is denoted by reference numeral 1b. , The artificial grass 1 arranged side by side on the right side of the artificial grass 1a in the center is represented by reference numeral 1c, and the artificial grass 1 arranged side by side on the left side of the artificial grass 1a is represented by reference numerals 1d, 1f,. The artificial turf 1 arranged side by side on the right side of the artificial turf 1c is denoted by reference numerals 1e, 1g,... (See FIG. 2).
[0018]
Next, an adhesive is applied to the left and right side edges of the underside of the underpad 13 of each artificial grass 1 (the left and right inner edges of the outermost artificial grass 1), and the reinforcing tape T is bonded. (See FIG. 3). If the reinforcing tape T is adhered to the back pad side edge of the underpad 13 of each artificial lawn 1, the central artificial lawn 1a is turned over so that the lawn leaf 12 faces upward (see FIG. 4). Then, the artificial grass 1b juxtaposed on the left side of the inverted artificial grass 1a is turned upside down on the artificial grass 1a in the center, and the side edges of the artificial grass 1a and 1b are aligned. Then, the side edges of the artificial turf 1a, 1b are sewn using a sewing machine (see FIG. 6). When the sewing of the side edges of the artificial grasses 1a and 1b is completed, the artificial grass 1b is folded back around its sewn portion, so that the central artificial grass 1a and the artificial grass 1b juxtaposed on the left side thereof are separated from each other. The connection can be made with the turf leaves 12, 12 facing up (see FIG. 7).
[0019]
Next, the artificial turf 1c juxtaposed on the right side of the central artificial turf 1a is lifted upside down on the central artificial turf 1a (see FIG. 8). The side edges of the lawns 1a and 1c are sewn with a sewing machine, and the artificial lawn 1c is folded around the sewn portion, so that the central artificial lawn 1a and the artificial lawn 1c juxtaposed on the right side of the lawn 1c are sewn. , 12 on top.
[0020]
Thereafter, the artificial lawn 1d juxtaposed on the left side of the artificial lawn 1b previously sewn was similarly connected by sewing to the artificial lawn 1b, and then juxtaposed on the right side of the artificial lawn 1c previously sewn. Similarly, the artificial grass 1e is sewn and connected to the artificial grass 1c, and then the artificial grass 1 adjacent to the previously sewn artificial grass 1 is sewn and connected alternately to the left and right, and the required number of sheets are connected until the set width is reached. To form the main body artificial grass 10.
[0021]
In this way, by sewing and connecting the plurality of artificial grasses 1 alternately to the left and right, it is possible to spend a preparation work for sewing the other left and right artificial grass 1 while sewing the left or right artificial grass 1. This makes it possible to form the artificial grass turf 10 by connecting it easily and in a short time.
[0022]
In this manner, the artificial grass turf 10 can be laid on the ground surface to form an artificial grass turf, and various sports can be performed.
By the way, in order to utilize the artificial turf ground for multiple purposes, it is necessary to wind up and remove the main body artificial turf 10 as it is or to lay it out. In this case, the weight of the artificial turf 10 becomes large and mechanical force must be used for winding and unwinding. At this time, a large pulling force acts on the artificial turf 10 due to its weight. . When the main body artificial grass 10 is wound into a roll, the underpad 13 of the artificial grass 1 is sewn with the sewing thread S. A difference in tension acting on the sewing thread S occurs due to a difference in inner and outer diameters due to the thickness of the lawn 1, and as a result, undulation-like wrinkles may be generated at a connection portion of the artificial lawn 1. If such wrinkles occur, the game will be hindered.
[0023]
Therefore, in the artificial turf 10 described above, there is no problem in the case of an artificial turf ground in which the artificial turf 10 is permanently installed on the ground. However, in order to utilize the ground for multiple purposes, the artificial turf 10 may be wound as necessary. It cannot be used for an artificial grass ground used for picking up or extending.
[0024]
In view of the above, in the second embodiment of the artificial lawn connection structure of the present invention, even if a load acts on the artificial lawn 1 during a game, the load is reliably supported and the artificial lawn 1, 1 An object of the present invention is to provide a connection structure that does not generate a gap in a connection portion and that does not generate wrinkles in the connection portion when the connection portion is wound by utilizing mechanical force.
[0025]
FIG. 9 shows a second embodiment of the artificial turf connection structure of the present invention, in which a plurality of long artificial turf 1 are connected in the width direction to form a main artificial turf 10A. Here, each artificial turf 1 forms a lawn leaf 12 on a synthetic resin base cloth 11 and heat-bonds an under pad 13 to the back surface of the synthetic resin base cloth 11 in the same manner as in the above-described embodiment. It is configured.
[0026]
A reinforcing tape T is adhered to the back edge of the synthetic resin base cloth 11 of each artificial turf 1 via an adhesive, and the artificial turf 1, 1 adjacent to the artificial turf 1, 1 is inserted through the reinforcing tape T. Since the side edges of the synthetic resin base cloths 11 and 11 are sewn with the sewing thread S, the reinforcing tape T itself can support the sewing thread S, and the cured adhesive is used as the synthetic resin base cloth. 11 can reinforce the woven structure of the side edge, and a large connection strength can be secured. Therefore, even if a load acts on the sewing connection portion of the artificial turf 1, 1, the load can be reliably supported, and the woven texture of the side edge of the synthetic resin base cloth 11 of the artificial turf 1 can be reduced. It is possible to reliably prevent a gap from being generated by being disturbed.
[0027]
When the artificial turf 10A is wound up or unwound using mechanical force, the side edge of the synthetic resin base cloth 11 which is much thinner than the thickness of the underpad 13 is reinforced with a reinforcing tape T. , The inner and outer diameters of the sewn portion do not differ from each other, and the generation of wrinkles can be reliably prevented.
[0028]
By the way, when the reinforcing tape T is adhered to the back side edge of the synthetic resin base cloth 11 of each artificial lawn 1, the side edge of the under pad 13 of each artificial lawn 1, 1 is prior to the work. Peeled over a certain width. Then, after sewing the side edges of the synthetic resin base cloths 11 and 11 of the pair of adjacent artificial grasses 1 and 1, the under pad of the synthetic resin base cloths 11 and 11 of the pair of adjacent artificial grasses 1 and 1 is sewn. An under pad 131 is adhered to the rear-side edge portion from which 13 has been peeled off via an adhesive.
[0029]
The adhesive is preferably a flexible adhesive in the same manner as in the first embodiment in consideration of the discomfort during the game and the workability of sewing, as well as the bending action at the time of winding the artificial turf 10A.
[0030]
Next, the case where the main body artificial grass 10A is formed will be described. As in the case of the first embodiment, a plurality of long artificial grass 1 cut into a required length are carried in a set width. The artificial grasses 1 are arranged side by side in the width direction such that the underpad 13 faces upward.
[0031]
Here, the reference numerals assigned to the artificial grass 1 are the same as those assigned to the artificial grass 1 in FIG.
When the transport of the artificial turf 1 is completed, the left and right side edges of the under pad 13 of each artificial turf 1 (the left and right inner side edges of the outermost artificial turf 1) are peeled over a certain width. After that (see FIG. 10), an adhesive is applied to the back edge of the synthetic resin base cloth 11 from which the underpad 13 has been peeled off, and the reinforcing tape T is bonded (see FIG. 11).
[0032]
When the reinforcing tape T is adhered to the back edge of the synthetic resin base cloth 11 of each artificial lawn 1, the artificial grass 1 a in the center is turned over so that the grass leaf 12 is on the upper side (FIG. 4). reference). Then, the artificial grass 1b juxtaposed on the left side of the inverted artificial grass 1a is turned upside down on the artificial grass 1a in the center, and the side edges of the artificial grass 1a and 1b are aligned. Then, the side edges of the synthetic resin base cloths 11, 11 of the artificial turf 1a, 1b are sewn using a sewing machine (see FIG. 12). When the sewing of the side edges of the artificial turf 1a, 1b is completed, the artificial turf 1b is further shifted toward the central artificial turf 1a, and the sewn sides of the synthetic resin base cloths 11, 11 of the artificial turf 1a, 1b. The edge is moved laterally to a flat position (see FIG. 13). Thereafter, an adhesive is applied to the back side edges including the sewn portions of the synthetic resin base cloths 11, 11 of the artificial grasses 1a, 1b, and the underpad peeled off from the artificial grasses 1a, 1b first is removed. The under pad 131 is adhered so as to be filled (see FIG. 14). Next, the artificial grass 1b is folded back around its sewn portion, so that the central artificial grass 1a and the artificial grass 1b arranged on the left side thereof can be connected with their grass leaves 12, 12 facing up. (See FIG. 7).
[0033]
Next, the artificial turf 1c juxtaposed on the right side of the central artificial turf 1a is lifted upside down on the central artificial turf 1a (see FIG. 8). The side edges of the lawns 1a, 1c are sewn with a sewing machine, and the underpad 131 is bonded to the back side edges of the synthetic resin base cloths 11, 11 of the artificial lawns 1a, 1c via an adhesive. By folding the artificial lawn 1c around its sewn portion, the central artificial lawn 1a and the artificial lawn 1c juxtaposed on the right side thereof can be connected with their grass leaves 12, 12 facing up.
[0034]
Thereafter, by performing the same operation, the artificial lawn 1d arranged side by side on the left side of the artificial lawn 1b previously sewn is connected to the artificial lawn 1b by sewing, and then arranged on the right side of the artificial lawn 1c previously sewn. The artificial grass 1e provided is sewn and connected to the artificial grass 1c, and then the artificial grass 1 adjacent to the previously sewn artificial grass 1 is alternately sewn and connected to the left and right, and the required number of sheets are connected until the set width is reached. To form the main body artificial grass 10A.
[0035]
Also in this embodiment, it is possible to spend a preparation work for sewing the other left and right artificial lawn 1 while sewing the left and right artificial lawn 1, and connect the main body artificial lawn 10A simply and in a short time. It can be formed.
[0036]
The artificial turf 10A thus formed has the underpad 32 bonded to the winding-side main shaft conductive cloth 2 and the conductive cloth 31 formed by bonding the underpad 22 to the conductive cloth 21 at the front and rear ends thereof. At the same time, after one end of the leading end fitting guide cloth 3 on the drawer side, which is fixed by winding the tip fitting 33 around the guiding cloth 31 (see FIGS. 15 and 16), it is not shown in detail, What is necessary is just to connect the other end of the main shaft guide cloth 2 to the housed winding device.
[0037]
Then, when a winding device (not shown) is driven, winding is started from the main shaft guide cloth 2 on the winding side, and finally the main body artificial grass 10A is wound. On the other hand, when laying the artificial grass turf 10A, a wire is connected to the other end of the tip metal fitting cloth 3, and the wire is wound up by a winding device (not shown) to pull out the artificial turf 10A from the pit. Can be laid.
[0038]
In this way, the artificial grass turf 10A connected without separating each artificial grass 1 is integrally wound or unwound, thereby forming the artificial grass turf by a separable artificial grass such as a fastener. The work time required for winding or unwinding can be greatly reduced as compared with the winding or unwinding method for each artificial grass constituting the artificial turf.
[0039]
As a specific example, a nylon turf having a height of 14 mm was planted on a polyester woven fabric, and a 10 mm-thick polyethylene foam underpad was adhered to the back of the fabric. .6 m and 17 m of artificial grass having a length of 80 m are prepared, and the back side edge of the artificial grass base fabric is reinforced with a reinforcing tape obtained by coating the surface of a polyester base fabric with vinyl chloride, A pair of adjacent artificial grasses was sewn with sewing thread made of polyester to form a main body artificial grass having a length of 80 m and a width of 60 m.
[0040]
In the above-described embodiment, the reinforcing tape T is bonded via an adhesive to the back side edge of the synthetic resin base cloth 11 of the artificial grass 1 as an example, but as shown in FIG. A reinforcing tape T may be adhered to the underpad 13 that has been peeled off while leaving a thickness of less than 5 mm, preferably 3 mm or less, and sewn to form the main body artificial grass 10B. That is, if the underpad 13 is sewn in a state where the thickness of the underpad 13 exceeds 5 mm, as described above, the tension acting on the sewing thread S due to the difference in inner and outer diameters due to the thickness of the underpad 13 at the time of winding the artificial grass turf 10B is reduced. This is because there is a possibility that wrinkles may be generated. As described above, the method of peeling while leaving a part of the underpad 13 can be applied to a case where the underpad 13 has a laminated structure of a plurality of peelable layers.
[0041]
An underpad 132 is adhered to the back side edge of the underpad 13 where the artificial grasses 1 and 1 are left via an adhesive.
Further, as shown in FIG. 18, in the case of the artificial lawn 1 not using the underpad 13, the reinforcing tape T is directly adhered to the back surface of the synthetic resin base cloth 11, and a pair of adjacent artificial lawns 1 is similarly formed. , 1 in this order to form the main body artificial grass 10C.
[0042]
Also in the embodiment shown in FIGS. 17 and 18, the load acting on the sewing connection portion of the artificial lawn 1, 1 can be reliably supported, and the side edge of the synthetic resin base cloth 11 of the artificial lawn 1, In addition to reliably preventing the occurrence of gaps by disturbing the weaving structure of the artificial turf, when the artificial turf 10B, 10C is wound up or unwound using mechanical force, the difference between the inner and outer diameters of the sewn portion is reduced. No wrinkles occur, and wrinkles can be reliably prevented from occurring.
[0043]
【The invention's effect】
As described above, according to the artificial grass connection structure of the first aspect of the present invention, the strength of the connection portion between the pair of adjacent artificial grasses can be secured, and even if a load acts on the sewing connection portion, The weaving structure of the side edge of the synthetic resin base fabric of the artificial turf is not disturbed, and the generation of the gap at the connecting portion can be reliably prevented.
[0044]
Further, according to the artificial grass connection structure of the second and third aspects of the present invention, the strength of the connection portion between the pair of adjacent artificial grasses can be secured, and a load acts on the sewing connection portion. In addition, the weaving structure of the side edge portion of the synthetic resin base cloth of the artificial turf is not disturbed, and the generation of the gap at the connection portion can be reliably prevented. Also, even when the artificial turf of the main body is rolled up and pulled out using mechanical force, wrinkles are not generated at the connection portion.
[0045]
On the other hand, according to the method for connecting artificial grass according to the fifth aspect of the present invention, it is possible to easily and quickly form a main body artificial grass in which the strength of the connection portion between a pair of adjacent artificial grasses is secured.
[0046]
According to the method for connecting artificial grass according to the sixth, seventh and eighth aspects of the present invention, the strength of the connecting portion between the pair of adjacent artificial grasses is ensured, and the winding is performed using mechanical force. The artificial turf of the main body, which does not cause wrinkles in the connection portion even when it is taken, can be formed easily and in a short time.
