Description

【０００１】
【発明の属する技術分野】
本発明は、地面用境界材に関し、詳しくは、材質や植裁、性質の異なる地面の境界を区画するために使用する地面用境界材であって、特に、隣接する地面用境界材同士の連結構造に関するものである。
【０００２】
【従来の技術】
従来、材質や植裁等が異なる地面を区画する際には、木板や樹脂製の波板等を適当に使用しており、地面用境界材として専用に用意されたものはなかった。また、海外においては、帯状の樹脂製境界材が用いられているが、これらは、可撓性を有する境界材にアンカー部材を貫入させ、これを地面に斜めに打込んで施工するようにしている。
【０００３】
【発明が解決しようとする課題】
しかし、近年では、多様な植裁、圃路等を造成する場合が多く、境界線も長くなる傾向にあるため、複数の地面用境界材同士を必要に応じて連結する必要があるが、従来は、専用の連結具を別途用意してその都度連結しているのが実状である。
【０００４】
そこで本発明は、地面用境界材同士の連結を容易にかつ確実に行うことができる地面用境界材を提供することを目的としている。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本発明の第１の地面に境界線を画するための地面用境界材は、地面用境界材の両端に、隣接する地面用境界材同士を上下方向に嵌合する雄雌嵌合構造で連結するための連結部をそれぞれ一体形成し、該両端の連結部のうち、一方が雄連結部、他方が雌連結部であり、前記雌連結部は、水平方向断面が正多角形で形成され、前記雄連結部は、雌連結部の正多角形の対向する二辺の内面に沿って挿入される二枚の弾性突片からなり、この弾性突片の先端には、結合時に雌連結部の下辺に係合する係合爪が設けられていることを特徴としている。
【０００６】
さらに、本発明の第２の地面に境界線を画するための地面用境界材は、地面用境界材の両端に、隣接する地面用境界材同士を上下方向に嵌合する雄雌嵌合構造で連結するための連結部をそれぞれ一体形成し、該両端の連結部のうち、一方が雄連結部、他方が雌連結部であり、前記雌連結部及び雄連結部は、水平方向断面が正多角形で形成されていることを特徴としている。
【０００７】
また、本発明の第３の地面に境界線を画するための地面用境界材は、地面用境界材の上下両側縁部に異なる形状の境界表示部を形成するとともに、両境界表示部の内部形状又は外部形状を共通の連結具で連結可能な形状に形成したことを特徴としている。
【０００８】
【発明の実施の形態】
図１乃至図３は、本発明の地面用境界材の一形態例を示すもので、図１は正面図、図２は平面図、図３は要部の平面図である。この地面用境界材１０は、適当な幅及び長さを有する射出成形材であって、適当な厚さの板状本体部１１に所定間隔で薄肉の折曲可能部１２を設けるとともに、この折曲可能部１２の上方を除く板状本体部１１の上端に幅広の天板部１３を設けたものである。また、天板部１３の中央には地面用境界材１０を打込む際の打撃目標となる頭部１４が設けられており、この頭部１４の下方には、打込み力を本体下部に確実に伝達するための補強リブ１５が設けられている。さらに、板状本体部１１の下端部は、打込み力を軽減するために先鋭化されるとともに、補強リブ１５部分が最下端部となり、折曲可能部１２が最上部となるような凹凸形状に形成されている。
【０００９】
また、板状本体部１１の下部には、板状本体部１１から側方に突出した抜止め部１６が設けられており、前記折曲可能部１２の側方には、該折曲可能部１２に沿う厚肉の強化部１７が本体部表面に交互に突出するようにして設けられている。
【００１０】
そして、板状本体部１１の長さ方向の両端部には、板状本体部１１同士を接続するための雄連結部１８と雌連結部１９とが設けられている。なお、天板部１３の下方に設けられている小通孔２０は、地面用境界材１０を折曲可能部１２に沿って折曲げたときに、折曲げ状態を保持するための固定具を装着する固定具装着部である。
【００１１】
前記雌連結部１９は正方形の筒状に形成されており、雄連結部１８は、雌連結部１９の対向する二辺の内面に沿って挿入される二枚の弾性突片１８ａ，１８ａからなるものであって、この弾性突片１８ａ，１８ａの先端には、結合時に雌連結部１９の下辺に係合する係合爪１８ｂが設けられている。また、雄連結部１８の根元には、雌連結部１９への挿入量を規制する規制部２１が設けられており、地面用境界材１０同士を連結する際に、この規制部２１が雌連結部１９の上辺に当接するまで雄連結部１８を押込むと、前記係合爪１８ｂが雌連結部１９の下辺に係合するとともに、天板部１３の高さが揃うようにしている。
【００１２】
したがって、この地面用境界材１０を連結する際には、雄連結部１８と雌連結部１９とを上下方向から嵌合させるだけでよく、専用の連結具を使用するものに比べて容易に連結作業を行うことができる。また、雌連結部１９を正方形状としているので、隣接する地面用境界材１０を直角方向に連結することもできる。
【００１３】
すなわち、図４及び図５の平面図に示すように、雄連結部１８及び雌連結部１９を正六角形状とした場合は、直線方向や直角方向だけでなく、４５度方向にも容易にかつ確実に連結することができる。
【００１４】
図６は本発明の地面用境界材の他の形態例を示す断面図である。この地面用境界材３１は、ポリエチレン、ポリプロピレン、ポリ塩化ビニル等の可撓性の合成樹脂からなる押出成形材であって、所定の高さ寸法を有する帯状の長尺材となっている。地面用境界材３１の上下両側縁部には、境界線における地表部分の形状を円形あるいは四角形に選択できるように、一方に断面円形の中空体からなる境界表示部３２が、他方に断面四角形の中空体からなる境界表示部３３が設けられている。
【００１５】
このような地面用境界材３１同士の連結は、図７に斜視図で示すように、両地面用境界材３１同士の境界表示部３２内に、棒状の連結具４１の両端をそれぞれ挿入することにより行われる。したがって、図６に示すように、円形の境界表示部３２の内径と、四角形の境界表示部３３における内接円の直径とが同一になるように、境界表示部３２，３３の内部形状を設定しておくことにより、一種類の丸棒状の連結具４１によって境界表示部３２，３３同士を接続することができ、境界表示部３２と境界表示部３３とを連結することもできる。
【００１６】
また、円形の境界表示部３２の外径と、四角形の境界表示部３３における外接円の直径とを同一とした形状に形成しておくことにより、図８に側面図で示すように、境界表示部３２，３３の外側に嵌合する円形状の連結具４２を使用することができる。さらに、四角形の境界表示部３３の外側形状に対応する四角形の内接円の直径と、円形の境界表示部３２の外径とを同一とした形状に形成しておくことにより、図９に側面図で示すように、境界表示部３２，３３の外側に嵌合する四角形状の連結具４３を使用することができる。このように、境界表示部の外側に嵌合する連結具４２，４３の場合は、境界表示部が中実のものにも対応することができる。
【００１７】
このような連結具の形状は、地面用境界材３１の上下に形成する境界表示部の形状に応じて選択することができ、例えば、図１０に断面図で示すように、一方に五角形の境界表示部３４を、他方に四角形の境界表示部３５を設けた地面用境界材３１の場合は、五角形の境界表示部３４に、四角形の境界表示部３５の内部形状に対応した四角形部分を形成しておくことにより、四角形の棒状連結具４４を用いて両境界表示部３４，３５を連結することができる。
【００１８】
さらに、図１１に示すように、中空形状の境界表示部３６同士を連結する場合は、芯材部４５の周囲に複数の可撓性突片４６を設けた連結具４７を使用し、可撓性突片４６を変形させて境界表示部３６内に圧入することにより、様々な形状の境界表示部同士を連結することができる。
【００１９】

The ground boundary material 10 is an injection-molded material having an appropriate width and length, and is provided with a thin bendable portion 12 at a predetermined interval on a plate-like main body portion 11 having an appropriate thickness. A wide top plate portion 13 is provided at the upper end of the plate-like main body portion 11 except above the bendable portion 12. In addition, a head 14 is provided at the center of the top plate 13 as a hitting target when the ground boundary material 10 is driven, and the driving force is surely applied to the lower part of the main body below the head 14. Reinforcing ribs 15 are provided for transmission. Further, the lower end portion of the plate-like main body portion 11 is sharpened to reduce the driving force, and has a concavo-convex shape such that the reinforcing rib 15 portion is the lowermost end portion and the bendable portion 12 is the uppermost portion. Is formed.
[0009]
Further, a retaining portion 16 that protrudes laterally from the plate-like main body portion 11 is provided at the lower portion of the plate-like main body portion 11, and the foldable portion is located on the side of the foldable portion 12. 12 are provided so as to protrude alternately on the surface of the main body.
[0010]
And the male connection part 18 and the female connection part 19 for connecting the plate-shaped main-body parts 11 are provided in the both ends of the length direction of the plate-shaped main-body part 11. As shown in FIG. The small through hole 20 provided below the top plate portion 13 is a fixing tool for holding the bent state when the ground boundary material 10 is bent along the bendable portion 12. It is a fixture mounting part to be mounted.
[0011]
The female connecting portion 19 is formed in a square cylindrical shape, and the male connecting portion 18 includes two elastic protrusions 18a and 18a inserted along the inner surfaces of two opposite sides of the female connecting portion 19. In addition, an engagement claw 18b that engages with the lower side of the female connecting portion 19 at the time of coupling is provided at the tip of the elastic protrusions 18a, 18a. Further, at the base of the male connecting portion 18, a restricting portion 21 for restricting the amount of insertion into the female connecting portion 19 is provided. When the ground boundary material 10 is connected, the restricting portion 21 is connected to the female connecting portion 19.

Therefore, as shown in FIG. 6, the internal shapes of the boundary display portions 32 and 33 are set so that the inner diameter of the circular boundary display portion 32 and the diameter of the inscribed circle in the quadrangular boundary display portion 33 are the same. By doing so, the boundary display units 32 and 33 can be connected to each other by one type of round bar-shaped connector 41, and the boundary display unit 32 and the boundary display unit 33 can also be connected.
[0016]
Further, by forming the outer diameter of the circular boundary display portion 32 and the diameter of the circumscribed circle in the quadrangular boundary display portion 33 into the same shape, as shown in the side view of FIG. A circular connector 42 that fits outside the portions 32 and 33 can be used. Further, by forming the quadrilateral inscribed circle diameter corresponding to the outer shape of the quadrangular boundary display portion 33 and the outer diameter of the circular boundary display portion 32 into the same shape, FIG. As shown in the figure, a rectangular connector 43 that fits outside the boundary display portions 32 and 33 can be used. Thus, in the case of the couplers 42 and 43 fitted outside the boundary display portion, the boundary display portion can correspond to a solid one.
[0017]
The shape of such a coupling tool can be selected according to the shape of the boundary display portions formed above and below the ground boundary material 31. For example, as shown in the sectional view of FIG. In the case of the ground boundary material 31 provided with the display section 34 and the quadrangular boundary display section 35 on the other side, a quadrangular portion corresponding to the internal shape of the quadrangular boundary display section 35 is formed on the pentagonal boundary display section 34. Thus, both the boundary display parts 34 and 35 can be connected by using a rectangular bar-shaped connector 44.
[0018]
Further, as shown in FIG. 11, when connecting the hollow boundary display portions 36 to each other, a connecting tool 47 in which a plurality of flexible protrusions 46 are provided around the core member portion 45 is used. By deforming the protruding protrusion 46 and press-fitting it into the boundary display section 36, the boundary display sections of various shapes can be connected to each other.
