【００１１】
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。
【００１２】
合成樹脂製フェンス本体１は、通常図１に示すように上縁枠部３、左縁枠部４、右縁枠部５及び下縁枠部６より成るフェンス枠部７と、該フェンス枠部７の内側に形成されたフェンス網目部８と、該フェンス網目部８の中央に垂直に形成されたフェンス骨部９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９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９が形成されなくともよい。
【００１３】
上縁枠部３は、平板状や四角い筒状であってもよいが、図４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４の上縁枠部３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３には、図６に示すように水平リブの内側に突出部２１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部分的に形成されていてもよい。
【００１４】
左縁枠部４には、上端に上方が開口して下方に底部１０を有する円筒状の嵌合用凹部１１が形成され、下端に下方が開口して上方に天井部１２を有する円筒状の嵌合用凹部１３が形成され、且つ嵌合用凹部１１と嵌合用凹部１３との間に左縁枠部４に沿って延びたリブ１４が形成されている。
【００１５】
右縁枠部５には、左縁枠部４と同様に上端に上方が開口して下方に底部１５を有する円筒状の嵌合用凹部１６が形成され、下端に下方が開口して上方に天井部１７を有する円筒状の嵌合用凹部１８が形成され、且つ嵌合用凹部１６と嵌合用凹部１８との間に右縁枠部５に沿って延びたリブ１９が形成されている。
【００１６】
下縁枠部６は、図６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２０及び突出部２１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２２及び結合部材係止部２３が形成されているのが好ましい。
【００１７】
本発明に於いては、上縁枠部３に結合部材係止部を形成した場合、下縁枠部６には突出部２０及び突出部２１を形成しなくてもよく、該突出部が形成されない場合図４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わたって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６は図４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。
【００１８】
尚、下縁枠部６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３３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３、左縁枠部４、右縁枠部５及び下縁枠部６より成るフェンス枠部７の内側に斜め格子より成るフェンス網目部８が形成されているのが好ましいが、フェンス網目部８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。
【００１９】
フェンス網目部８の中央には、フェンス骨部９が形成されているのが好ましい。かかるフェンス骨部９には、上端に上方が開口して下方に底部２４を有する円筒状の嵌合用凹部２５が形成され、下端に下方が開口して上方に天井部２６を有する嵌合用凹部２７が形成され、且つ嵌合用凹部２５と嵌合用凹部２７との間に断面がエの字状のリブが形成される。
【００２０】
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９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。
【００２１】
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２２及び結合部材係止部２３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、該結合部材を単に図２に示す嵌合用凹部１１及び１６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。
【００２２】
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、例えば合成樹脂製フェンス本体１の結合部材係止部２２、２３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２２、２３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１３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２８の嵌合用凹部２９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１８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２８の嵌合用凹部２９’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２８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。
【００２３】
ブロック２８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２９及び２９’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２８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２８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２８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。
【００２４】
また、本発明に於いては、図３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１３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１１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１８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１６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１１及び嵌合用凹部１６を連結片３０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３０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３１の下方に２本の脚部３２、３２’を有するものを使用することができる。尚、図３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２７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２５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。
【００２５】
更に、本発明の合成樹脂製フェンスは、図２に示すのとは逆に上縁枠部３を下にし、嵌合用凹部１１及び１６に合成樹脂製結合部材２を嵌合し、さらにブロック２８の嵌合用凹部に嵌合して用いることができ、上縁枠部３には外側に傾斜リブ３３が形成されていないため、上縁枠部３の高さが地表面から比較的低くすることができ、従来かかる開口部に使用している覆い板等を用いなくとも済むというメリットがある。
【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が合成樹脂製フェンス本体１の脚部に固定して取り付けられていないで、合成樹脂製フェンス１内に取り外し可能に取り付けられている為に合成樹脂製結合部材２が破損され難い。

As shown in FIG. 1, the synthetic resin fence body 1 generally includes a fence frame portion 7 including an upper edge frame portion 3, a left edge frame portion 4, a right edge frame portion 5 and a lower edge frame portion 6, and the fence frame portion. 7 has a fence mesh portion 8 formed inside the fence mesh portion 8 and a fence bone portion 9 formed perpendicularly to the center of the fence mesh portion 8. In the synthetic resin fence main body of the present invention, when it is large, for example, about 1.5 m in width and about 1 m in length, it is preferable to have the fence bone portion 9 from strength maintenance, but strength is not so required. When it is small, the fence bone portion 9 does not have to be formed.
[0013]
The upper edge frame portion 3 may be a flat plate shape or a square tube shape, but it is preferable that the upper edge frame portion 3 is formed by ribs having a cross section as shown in FIG. The upper edge frame portion 3 in FIG. 4 is configured by horizontal ribs that are parallel in the vertical direction and vertical ribs that connect the two ribs. As shown in FIG. 6, the upper edge frame portion 3 may have a shape in which a protruding portion 21 is provided inside the horizontal rib and the synthetic resin coupling member 2 can be attached. The vertical ribs are preferably formed over the entire length of the upper and lower horizontal ribs from the viewpoint of maintaining strength. However, in some cases, the vertical ribs may be formed partially, or may be partially formed in the width direction of the horizontal ribs. It may be formed automatically.

That is, the ribs of the upper edge frame portion are constituted by horizontal ribs that are parallel in the vertical direction and vertical ribs that connect the two ribs. Moreover, although it is preferable from the maintenance of intensity | strength that the said vertical rib is formed over the whole length direction of an up-and-down horizontal rib, depending on the case, you may form partially. Further, the horizontal rib is formed with a coupling member locking portion 22 and a coupling member locking portion 23 for locking the synthetic resin coupling member 2 by the upper and lower four protruding portions 20 and the protruding portions 21, respectively. preferable.
[0017]
In the present invention, when the coupling member locking portion is formed in the upper edge frame portion 3, the lower edge frame portion 6 does not need to form the protruding portion 20 and the protruding portion 21, and the protruding portion is formed. If not, the cross-section may be formed by ribs having a square shape as shown in FIG. 4, or may be partially formed across the width direction of the horizontal ribs. At this time, if the strength can be sufficiently maintained, the lower edge frame portion 6 may have another shape such as a flat plate shape or a rectangular tube shape instead of the shape shown in FIG.
[0018]
The lower edge frame portion 6 is preferably formed with inclined ribs 33 from the vicinity of the left and right end portions of the flat lower edge frame portion to the left and right edge frame portions downward.
The synthetic resin fence of the present invention has a fence mesh portion 8 made of an oblique lattice inside a fence frame portion 7 consisting of an upper edge frame portion 3, a left edge frame portion 4, a right edge frame portion 5 and a lower edge frame portion 6. Although formed preferably, the mesh of the fence mesh portion 8 may have another shape such as a turtle shape or a square shape.

It is tubular. That is, when the synthetic resin coupling member 2 is fitted into the fitting recess at the lower part of the left and right edge frame portions, the fence body is turned upside down so that it can be fitted into the fitting recess such as a concrete block and grounded. In addition, when the same synthetic resin fence is further stacked thereon, the length needs to be able to be fitted into the fitting recesses of the left and right edge frame portions of the upper fence. Further, when the synthetic resin coupling member 2 is fitted in the fitting recesses at the upper part of the left and right edge frame parts, when the same synthetic resin fence is further stacked on the fence body, the left and right edge frame parts of the upper fence The length needs to be such that it can be fitted into the fitting recess, and can be grounded by turning the fence body upside down and fitting into the fitting recess such as a concrete block.
[0021]
In the synthetic resin fence according to the present invention, the synthetic resin coupling member 2 is engaged with the coupling member engagement portion 22 and the coupling member engagement portion 23 so that the synthetic resin fence does not protrude from the synthetic resin fence body 1. It can be removably mounted in the fence body 1. In this way, the synthetic resin coupling member 2 is detachably attached to the synthetic resin fence body 1 so that the fence and the coupling member do not have to be transported separately, and the storage space is also saved. There is a merit that you can. Further, when the fence of the present invention is used upside down, the connecting member can be simply operated by attaching it to the fitting recesses 11 and 16 shown in FIG. Furthermore, since the coupling member 2 is not fixedly installed on the synthetic resin fence, there is no problem that the coupling member is broken during transportation when used.
[0022]
In the present invention, the synthetic resin fence main body 1 and the synthetic resin coupling member 2 are individually molded, and for example, at least two synthetic resins are formed on the coupling member locking portions 22 and 23 of the synthetic resin fence main body 1. The synthetic resin fence according to the present invention is constructed by attaching the coupling member 2 and then transported to the construction site, civil engineering site, etc., and the coupling member of the synthetic resin fence main body 1 at the building site, civil engineering site, etc. The synthetic resin coupling member 2 is removed from the locking portions 22 and 23, and one end of the first synthetic resin coupling member 2 is fitted into the fitting recess 13 of the synthetic resin fence body 1 as shown in FIG. The other end of the synthetic resin coupling member 2 is fitted into the fitting recess 29 of the block 28, and one end of the second synthetic resin coupling member 2 is fitted into the fitting recess 18 of the synthetic resin fence main body 1. And let The other end of the synthetic resin connecting member 2 by fitting into the fitting recess 29 of another block 28 ', may be installed synthetic resin fence. Further, without using the block 28, a fitting recess for fitting the synthetic resin coupling member 2 on the ground may be formed, and the synthetic resin coupling member 2 may be fitted into the recess.

It can be manufactured by filling concrete with a hardened material. The block 28 is heavier than the fence body, and has a shape in which the area of the upper part is narrow and the area of the lower part is wide so that the center of gravity is lower than half in the height direction. Further, it is particularly preferable that the bottom corner is cut at an appropriate angle, preferably 45 °. Thus, when the corner of the bottom surface of the block 28 is cut at an appropriate angle, if an excessive load is applied to the synthetic resin fence installed on the block from the side surface, the cut surface of the block 28 It stops once and does not fall immediately. If the curl (roundness) is appropriately given to the corner of the cut part, it will be restored without falling if the applied load is eliminated halfway.
[0024]
In the present invention, as shown in FIG. 3, after the first-stage synthetic resin fence is continuously installed, one end of the synthetic resin coupling member 2 is connected to the second-stage synthetic resin fence main body 1. The other end of the synthetic resin coupling member 2 is fitted into the fitting concave portion 11 of the first-stage synthetic resin fence body 1 and one end of another synthetic resin coupling member 2 is fitted into the fitting concave portion 13.

It is preferable to improve the strength.
[0025]
Further, the synthetic resin fence of the present invention has the upper edge frame portion 3 down, and the synthetic resin coupling member 2 is fitted into the fitting recesses 11 and 16, as shown in FIG. Since the upper edge frame portion 3 is not formed with the inclined rib 33 on the outer side, the height of the upper edge frame portion 3 should be relatively low from the ground surface. Thus, there is an advantage that it is not necessary to use a cover plate or the like conventionally used for the opening.
