合成樹脂製フェンス本体１及び合成樹脂製結合部材２は、ポリエチレン、ポリプロピレン、ＡＢＳ樹脂、ポリカーボネート等の合成樹脂によって成形することができる。
【００１１】
合成樹脂製フェンス本体１は、通常図１に示すように左端から斜め上方に傾斜した左側傾斜縁部３、右端から斜め上方に傾斜した右側傾斜縁部４及び両傾斜縁部に連なる水平縁部５より成る上縁枠部６、左縁枠部７、右縁枠部８並びに下縁枠部９により構成されるフェンス枠部１０と、該フェンス枠部１０の内側に形成されたフェンス網目部１１と、該フェンス網目部１１の中央に垂直に形成されたフェンス骨部１２とを有している。本発明での合成樹脂製フェンス本体では、それが例えば横約１．５ｍ、縦約１ｍのように大きい場合は強度保持からフェンス骨部１２を有しているほうが好ましいが、強度をそれほど要求されない小さい場合にはフェンス骨部１２が形成されなくともよい。
【００１２】
上縁枠部６は、平板状や四角い筒状であってもよいが、図５に示すように断面がエの字状のリブによって形成されているのが好ましい。図５の上縁枠部６については、上下で平行する水平リブと両リブを連結する垂直リブによって構成されている。かかる上縁枠部６には、図７に示すように水平リブの内側に突出部２４を設けて合成樹脂製結合部材２を取り付けられるような形状であってもよい。また、上記垂直リブは上下の水平リブの長さ方向の全部にわたって形成されているのが強度の保持から好ましいが、場合によっては部分的に形成されてもよく、また水平リブの幅方向にわたって部分的に形成されていてもよい。
【００１３】
左縁枠部７には、上端に上方が開口して下方に底部１３を有する円筒状の嵌合用凹部１４が形成され、下端に下方が開口して上方に天井部１５を有する円筒状の嵌合用凹部１６が形成され、且つ嵌合用凹部１４と嵌合用凹部１６との間に左縁枠部７に沿って延びたリブ１７が形成されている。
【００１４】
右縁枠部８には、左縁枠部７と同様に上端に上方が開口して下方に底部１８を有する円筒状の嵌合用凹部１９が形成され、下端に下方が開口して上方に天井部２０を有する円筒状の嵌合用凹部２１が形成され、且つ嵌合用凹部１９と嵌合用凹部２１との間に右縁枠部８に沿って延びたリブ２２が形成されている。
【００１５】
下縁枠部９は、図７に示すように縦棒が横にずれた断面がエの字状のリブによって形成されているのが好ましい。即ち、該上縁枠部のリブが上下で平行する水平リブと両リブを連結する垂直リブによって構成されている。また、上記垂直リブは上下の水平リブの長さ方向の全部にわたって形成されているのが強度の保持から好ましいが、場合によっては部分的に形成されてもよい。また、該水平リブにはそれぞれ上下４箇の突出部２３及び突出部２４によって合成樹脂製結合部材２を係止する結合部材係止部２５及び結合部材係止部２６が形成されているのが好ましい。
【００１６】
本発明に於いては、上縁枠部６に結合部材係止部を形成した場合、下縁枠部９には突出部２３及び突出部２４を形成しなくてもよく、該突出部が形成されない場合図５に示すように断面がエの字状のリブによって形成されても、或いは水平リブの幅方向に部分的に形成されてもよい。この際、強度が充分保持でき得れば、下縁枠部９は図５に示す形状でなく平板状や四角い筒状等の他の形状であってもよい。
【００１７】
尚、下縁枠部９は、平坦な下縁枠部の左右の端部近傍から左右縁枠部に下方に向かって傾斜リブ３６が形成されているのが好ましい。
本発明の合成樹脂製フェンスは、上縁枠部６、左縁枠部７、右縁枠部８及び下縁枠部９より成るフェンス枠部１０の内側に斜め格子より成るフェンス網目部１１が形成されているのが好ましいが、フェンス網目部１１の網目が亀の子状や四角形状等の他の形状のものであってもよい。
【００１８】
フェンス網目部１１の中央には、フェンス骨部１２が形成されているのが好ましい。かかるフェンス骨部１２には、上端に上方が開口して下方に底部２７を有する円筒状の嵌合用凹部２８が形成され、下端に下方が開口して上方に天井部２９を有する嵌合用凹部３０が形成され、且つ嵌合用凹部２８と嵌合用凹部３０との間に断面がエの字状のリブが形成される。
【００１９】
本発明での合成樹脂製結合部材２は、右縁枠部、左縁枠部、必要によりフェンス骨部１２の嵌合用凹部に嵌合し、且つ該嵌合部よりも長くなるようにした円管状のものである。即ち、合成樹脂製結合部材２が左右縁枠部の下部の嵌合用凹部に嵌合される場合、コンクリートブロック等の嵌合用凹部に嵌合して接地され得るように、また、フェンス本体を逆さまにし、その上に同じ合成樹脂製フェンスを更に積む場合に上部のフェンスの左右縁枠部の嵌合用凹部に嵌合され得るような長さである必要がある。また、合成樹脂製結合部材２が左右縁枠部の上部の嵌合用凹部に嵌合される場合、フェンス本体の上に同じ合成樹脂製フェンスを更に積む場合に上部のフェンスの左右縁枠部の嵌合用凹部に嵌合され得るように、また、フェンス本体を逆さまにしてコンクリートブロック等の嵌合用凹部に嵌合して接地され得るような長さである必要がある。
【００２０】
本発明に係わる合成樹脂製フェンスでは、合成樹脂製結合部材２を結合部材係止部２５及び結合部材係止部２６に係止させることにより、合成樹脂製フェンス本体１から突出することなく合成樹脂製フェンス本体１内に取り外し可能に取り付けることができる。このように、合成樹脂製結合部材２が合成樹脂製フェンス本体１内に取り外し可能に取り付けられることにより、該フェンスと該結合部材とを別々に搬送しなくても済み、しかも保管するスペースも節約できるというメリットがある。さらに、本発明のフェンスを天地を逆さまにして使用する場合、該結合部材２を単に図３に示すように嵌合用凹部１４及び１９に取り付けることによって簡便に作業できることになる。さらにまた、該結合部材２が合成樹脂製フェンスに固定して設置されていないため、使用する際運搬等で結合部材が破壊するという問題がない。かかる合成樹脂製結合部材２は、フェンス本体１に取付可能にするほうが好ましいが、フェンス本体１に上記結合部材係止部２５及び結合部材係止部２６を形成せずにフェンス本体１とは分離して保管、使用することができる。
【００２１】
本発明に於いては、合成樹脂製フェンス本体１と合成樹脂製結合部材２とを個別に成形し、合成樹脂製フェンス本体１の結合部材係止部２５、２６に少なくとも２本の合成樹脂製結合部材２を取り付けて本発明に係わる合成樹脂製フェンスを構成した後に、建築現場、土木作業現場等に輸送し、建築現場、土木作業現場等に於いて合成樹脂製フェンス本体１の結合部材係止部２５、２６から合成樹脂製結合部材２を取り外し、図２に示すように１本目の合成樹脂製結合部材２の一端を合成樹脂製フェンス本体１の嵌合用凹部１６に嵌合させるとともに該合成樹脂製結合部材２の他端をブロック３１の嵌合用凹部３２に嵌合させ、且つ２本目の合成樹脂製結合部材２の一端を合成樹脂製フェンス本体１の嵌合用凹部２１に嵌合させるとともに該合成樹脂製結合部材２の他端を別のブロック３１の嵌合用凹部３２’に嵌合させることにより、合成樹脂製フェンスを設置すればよい。また、上記ブロック３１を使用せずに、地上に合成樹脂製結合部材２を嵌合する嵌合用凹部を形成し、該凹部に合成樹脂製結合部材２を嵌合してもよい。
【００２２】
ブロック３１は、高さの低い円柱状若しくは角柱状のブロックとし、２個の嵌合用凹部３２及び３２’を形成したものが好ましく、ポリエチレン、ポリプロピレン等の合成樹脂をブロー成形した外殻体の内部にコンクリートを充填して硬化させることにより、製造することができる。かかるブロック３１は、フェンス本体よりも荷重が重いものであり、しかも重心が高さ方向で半分より下となるように形状的に上部の面積が狭く、下部の面積が広くなるような形体のもので、更に底面の隅部が適度な角度、好ましくは４５°にカットされているものが特に好ましい。このようにブロック３１の底面の隅部が適度な角度にカットされていると、該ブロックの上に設置された合成樹脂製フェンスに側面から過度の荷重がかかった場合、ブロック３１のカット面で一旦停止し、直ちに転倒せず、もしカット部分の角部に適当にカール（丸み）を与えておけばかかった荷重が途中で解消すると転倒せずに復元することにもなる。
【００２３】
また、本発明に於いては、図３に示すように合成樹脂製フェンス本体１を引っ繰り返し、１本目の合成樹脂製結合部材２の一端を合成樹脂製フェンス本体１の嵌合用凹部１４に嵌合させるとともに該合成樹脂製結合部材２の他端をブロック３１の嵌合用凹部３２に嵌合させ、且つ２本目の合成樹脂製結合部材２の一端を合成樹脂製フェンス本体１の嵌合用凹部１９に嵌合させるとともに該合成樹脂製結合部材２の他端を別のブロック３１の嵌合用凹部３２’に嵌合させて合成樹脂製フェンスを設置することにより、フェンス枠部１０の下端と設置面との間隔を小さくすることができ、上縁枠部５を設置面に近づけることができるためフェンス枠部１０の下端と設置面との間から犬等が不用意に侵入することを防止することができる。
【００２４】
ブロック３１は、高さの低い円柱状若しくは角柱状のブロックとし、２個の嵌合用凹部３２及び３２’を形成したものが好ましく、ポリエチレン、ポリプロピレン等の合成樹脂をブロー成形した外殻体の内部にコンクリートを充填して硬化させることにより、製造することができる。
【００２５】
また、本発明に於いては、図４に示すように一段目の合成樹脂製フェンスを連続して設置した後に、合成樹脂製結合部材２の一端を二段目の合成樹脂製フェンス本体１の嵌合用凹部１６に嵌合させるとともに該合成樹脂製結合部材２の他端を一段目の合成樹脂製フェンス本体１の嵌合用凹部１４に嵌合させ、且つ別の合成樹脂製結合部材２の一端を二段目の合成樹脂製フェンス本体１の嵌合用凹部２１に嵌合させるとともに該合成樹脂製結合部材２の他端を一段目の合成樹脂製フェンス本体１の１９に嵌合させ、次いで二段目の合成樹脂製フェンス本体１の隣接した嵌合用凹部１４及び嵌合用凹部１９を連結片３３で連結することにより、合成樹脂製本体１を縦横に接続した合成樹脂製フェンスを設置することができる。連結片３３は、ポリエチレン、ポリプロピレン等の合成樹脂によって形成することができ、例えば板状部３４の下方に２本の脚部３５、３５’を有するものを使用することができる。尚、図４に示すように合成樹脂製フェンス１を縦横に接続した合成樹脂製フェンスを設置する場合には、更に合成樹脂製結合部材２を使用し、合成樹脂製結合部材２の一端を二段目の合成樹脂製フェンス本体１の嵌合用凹部３０に嵌合させるとともに該合成樹脂製結合部材２の他端を一段目の合成樹脂製フェンス本体１の嵌合用凹部２８に嵌合させることにより、強度を向上させることが好ましい。
【００２６】
【発明の効果】
本発明に係わる合成樹脂製フェンスは、合成樹脂製結合部材２がフェンス本体に固定して取り付けられていないため該結合部材２が破損され難く、しかも上縁枠部５が設置面に向くように設置するとフェンス枠部１０と設置面との間隔が小さくなり、フェンス枠部１０の下端と設置面との間から犬等が不用意に侵入することを防止することができる。
