Description

【０００１】
【発明の属する技術分野】
本発明は、植樹された樹木をある程度大きくなるまで風等によって倒されないように支持するための樹木用支柱に関する。
【０００２】
【従来の技術】
図１１は従来より広く一般に使用されている樹木用支柱を示すもので、（Ａ）は正面図、（Ｂ）は側面図、（Ｃ）は平面図である。この樹木用支柱は、杉丸太よりなる左右一対の支柱部材イ，イと、両支柱部材イ，イの両端部同士をつなぐ杉丸太よりなる水平材ロと、間抜材等よりなる添え木ハとからなるもので、土中に埋まる支柱部材イ及び添え木ハの下端部側には防腐剤が塗布される。そして、この支柱を使用する時は、先ず添え木ハを樹木Ｔに添わせた状態で土中に打ち込み、次いで両支柱部材イ，イを樹木Ｔの近傍に土中に打ち込み、両支柱部材イ，イの上端部を水平材ロによりつないで（Ａ）に示すような鳥居形にした状態で、水平材ロの中央部をしゅろ縄ニによって樹木Ｔに縛りつけると共に、添え木ハをしゅろ縄ニで水平材ロに縛りつけ、また添え木ハの下端部をしゅろ縄ニで樹木Ｔに縛りつける。尚、樹木Ｔの結束部分には予め杉皮ホを巻き付けて傷が付かないようにする。
【０００３】
【発明が解決しようとする課題】
従来の樹木用支柱には上記のように木材が使用されていて、土中に打ち込まれる支柱部材イや添え木ハではその下端部側に腐食防止のための防腐剤が塗布されているが、樹木Ｔの成長により支柱が不要となって、支柱を焼却処分する際に、防腐剤の燃焼によって有毒ガスが発生すると云う問題があった。また従来の樹木用支柱では、支柱部材イそれ自体を土中に打ち込むようになっているため、その打ち込み作業に困難を要していた。
【０００４】
本発明は、支柱構成部材を金属で形成することによって上記の問題を解消すると共に、土中への打ち込み作業が容易に行える樹木用支柱を提供することを目的とする。
【０００５】
【課題を解決するための手段】
請求項１に係る発明は、植樹された樹木Ｔの近傍で土中に打ち込まれる左右一対の金属製杭部材１，１と、土中に打ち込まれる両杭部材１，１の夫々上端部に伸縮調整可能に接続される左右一対の金属製支柱本体２，２と、両支柱本体２，２の上端部同士をつなぐ金属製水平材３とからなり、水平材３の中央部が縛り紐４によって樹木Ｔに縛りつけられるようになっており、水平材３の中央部には、樹木Ｔの外周面部に対応する凹面状の係合部１８を備えたプラスチック製のカラー１６が外嵌固定されており、さらに支柱本体２および水平材３は、外周面の直径方向両側対称位置にリップ５，５付き溝６を全長に亘って形成すると共に両溝６，６の間に杭部材１を挿通案内する挿通案内路７を全長に亘って形成した同一断面形状の中空状のアルミ押し出し型材からなるもので、支柱本体２とこれの挿通案内路７に挿入された杭部材１とを連結するにあたり、支柱本体２の片方の溝６からねじ込まれるねじ具１０によって杭部材１を支柱本体２に押し付け固定するようにしたことを特徴とする。
【０００６】
請求項２は、請求項１に記載の樹木用支柱において、カラー１６の外周面部には、水平材３から樹木Ｔに亘って架け渡される縛り紐４を係合させる係合溝２０が形成されていることを特徴とする。
【０００７】
請求項３は、請求項１または２に記載の樹木用支柱において、水平材３の片方のリップ５，５付き溝６内に、この溝６に対し挿脱自在で且つ溝６内では一定角度範囲内しか回転しないナット１１を挿入配置し、このナット１１に、支柱本体２の一方の溝６内から他方の溝に亘って貫通させたボルト１２をねじ込むことにより、水平材３を支柱本体２に連結するようにしたことを特徴とする。
【０００８】
【発明の実施の形態】
図１は本発明に係る樹木用支柱の使用状態を示す正面図、図２はその側面図である。この樹木用支柱は、植樹された樹木Ｔの近傍で土中に打ち込まれる左右一対の鋼製杭部材１，１と、土中に打ち込まれた両杭部材１，１の夫々上端部に伸縮調整可能に接続される左右一対のアルミニウム製支柱本体２，２と、両支柱本体２，２の上端部同士をつなぐアルミニウム製水平材３とからなるもので、水平材３の中央部がしゅろ縄からなる縛り紐４によって樹木Ｔに縛り付けられるようになっている。
【０００９】
図３の（Ａ）は杭部材１を示し、（Ｂ）は支柱本体２を示す。（Ｃ）は（Ｂ）のＸ−Ｘ線拡大断面図で、支柱本体２の断面形状を示す。図４の（Ａ）は水平材３を示し、（Ｂ）は（Ａ）のＹ−Ｙ線拡大断面図で、水平材３の断面形状を示す。杭部材１は、鋼鉄材によって棒状に形成されたもので、先端部が尖っている。支柱本体２は、外周面の直径方向両側対称位置にリップ５，５付き溝６を全長に亘って形成すると共に、両溝６、６の間に杭部材１を挿通案内する挿通案内路７を全長に亘って形成した中空状のアルミ押し出し型材からなる。水平材３は、図４の（Ｂ）から分かるように、支柱本体２と全く同じ断面形状のアルミ押し出し型材からなるもので、外周面の直径方向両側対称位置にリップ５，５付き溝６を全長に亘り形成している。支柱本体２の上端部には合成樹脂製のキャップ８が、また水平材３の両端部には夫々合成樹脂製のキャップ９が装着される。
【００１０】
図５の（Ａ）は図１の矢印Ｖで示される部分の拡大正面図、（Ｂ）は（Ａ）のｖ−ｖ線断面図、（Ｃ）は（Ｂ）のボルト取付部分の横断面図であり、また図６の（Ａ）は図１の矢印Ｗで示される部分の拡大正面図、（Ｂ）は（Ａ）のｗ−ｗ線断面図、（Ｃ）は（Ｂ）のビス取付部分の横断面図である。先ず、図６を参照して杭部材１と支柱本体２とを連結するのに、杭部材１を支柱本体２の挿通案内路７に挿入した状態で、支柱本体２の下端部側と杭部材１の上端部側とを、支柱本体２の片方のリップ５，５付き溝６からねじ込まれるねじ具１０によって杭部材１を支柱本体２に押し付け固定するようにしている。詳しく説明すれば、支柱本体２には片方の溝６の底壁部６ａ下端部側の例えば３箇所にねじ挿通孔２５を明けておいて、この溝６内に３個の四角ナット１０ｂを回転不能状態に挿入し、そして各四角ナット１０ｂに螺入した六角孔付き止めねじ１０ａを前記ねじ挿通孔２５に挿通し、この止めねじ１０ａをねじ込んで先端部を杭部材１に押し付けることによって、杭部材１を支柱本体２に固定するようにしたもので、これによって杭部材１と支柱本体２とを任意の位置で簡単容易に連結固定でき、土中に打ち込まれた杭部材１の上端部に支柱本体２を伸縮調整可能に接続することができる。この場合、止めねじ１０ａの頭部及び四角ナット１０ｂを支柱本体２の溝６内に埋没させることができるので、体裁が良く、美観を損なうことがない。尚、上記止めねじ１０ａと四角ナット１０ｂとによってねじ具１０を構成する。
【００１１】
水平材３の両端部を両支柱本体２，２の上端部に連結して両支柱本体２，２の上端部同士をつなぐには、図５の（Ａ）〜（Ｃ）に示すように、水平材３の片方のリップ５，５付き溝６内に、この溝６に対し挿脱自在で且つこの溝６内では一定角度範囲内しか回転しない構造のナット１１を挿入配置し、このナット１１に、支柱本体２の一方のリップ５，５付き溝６の底壁部６ａから他方のリップ５，５付き溝６の底壁部６ａに亘って貫通させた六角穴付きボルト１２をねじ込んで締め付けることによって、水平材３を支柱本体２に連結することができる。この場合も、ボルト１２の頭が支柱本体２の溝６内に埋没されるので、体裁が良く、美観を損なうことがない。尚、図３の（Ｂ）及び図５の（Ｂ），（Ｃ）において、２４は支柱本体２の両溝６，６の底壁部６ａ，６ａを貫通するボルト挿通孔である。
【００１２】
図７の（Ａ）及び（Ｂ）は上記ナット１１を水平材３の片方のリップ５，５付き溝６内に挿入配置した状態を示し、（Ａ）は（Ｂ）のＵ−Ｕ線に沿って断面した断面図である。このナット１１は、水平材３の対向するリップ５，５の間隔ｓよりも径小の軸部１３と、長辺の長さａが水平材３の溝６の幅ｈより僅かに短く且つリップ５，５の間隔ｓよりは長く、短辺の長さｂがリップ５，５の間隔ｓより短く、そして１つの対角線上の両角部が夫々アール状に切除されてアール部ｒ，ｒを形成してなるヘッド部１４と、これら軸部１３及びヘッド部１４を貫通するねじ孔１５とから構成される。
【００１３】
従って、このナット１１を水平材３のリップ５，５付き溝６内に挿入するには、図７の（Ａ）の仮想線図示のようにヘッド部１４をその長手方向が水平材３の長手方向となるようにして挿入すればよく、こうして水平材３の溝６内に挿入したナット１１を、同図の仮想線図示位置から同図に関して時計回りに回転させると、９０度回転したところで同図の実線図示位置となって、それ以上回転せず、またこの実線図示位置から反時計回りに回転させると、１８０度回転して同図の実線図示位置となり、それ以上は回転しない。
【００１４】
しかして、図５の（Ｂ）及び（Ｃ）に示すように、ナット１１を水平材３のリップ５付き溝６内に同図の実線図示位置に挿入配置しておいて、このナット１１に、支柱本体２の一方のリップ５，５付き溝６から他方のリップ５，５付き溝６に亘って貫通させた六角穴付きボルト１２を螺入し、このボルト１２をねじ込み方向に回転させれば、ナット１１が伴回りせず、従って水平材３の表側からボルト１２による締付け作業を簡単に行うことができる。
【００１５】
また、図１及び図２に示すように、水平材３の中央部には、樹木Ｔの外周面部に係合可能な凹面状の係合部１８を備えたプラスチック製のカラー１６が外嵌固定されている。図８の（Ａ）はカラー１６を示す正面図、（Ｂ）はカラー１６の側面図、（Ｃ）はカラー１６の平面図である。また図９の（Ａ）はカラー１６の取付状態を示す正面図、（Ｂ）は同取付状態の側面図であり、図９は同取付状態の平面図である。
【００１６】
このプラスチック製カラー１６は、アルミニウム製の水平材３を直接樹木Ｔに当てて縛りつけると、気温の高い真夏時等においては樹木Ｔが焼けることから、これを防ぐために設けられるものであって、断面略Ｃ字形のカラー本体１７と、樹木Ｔの外周面部に対応する凹面部１８ａを形成した係合部１８と、からなり、カラー本体１７の基端部と係合部１８とに亘って貫通するボルト取付孔１９が２か所に設けられ、各ボルト取付孔１９は、係合部１８の凹面部１８ａに開口するボルト頭挿通孔部１９ａと、カラー本体１７の内面側に開口するボルト首部挿通孔部１９ｂとからなる。カラー本体１７の基端部に内向きに突出する断面略Ｔ字状の突出部１７ａは、図９の（Ｂ）に示すように、カラー１６を水平材３に外嵌させる時に水平材３の片方の溝６に嵌合するようになっている。カラー本体１７の外周面部には、水平材３と樹木Ｔとに亘って架け渡される縛り紐４を係合させる係合溝２０が正面視略Ｘ字状に形成されている。尚、図４に示すように、水平材３には中央部の２か所にカラー取付用のボルト挿通孔２１が両溝６，６を貫通するように設けてある。
【００１７】
上記のような構造のカラー１６を水平材３に取り付けるには、カラー１６を水平材３に対し図９の（Ｂ）に示すような状態に外嵌させ、水平材３の中央部において、ボルト２２を、係合部１８の凹面部１８ａに開口する各ボルト取付孔１９のボルト頭挿通孔部１９ａから水平材３側のボルト挿通孔２１を通して、カラー本体１７の突出部１７ａが嵌合している溝６と反対側の溝６に突入させ、その突入端部にナット２３を螺合して締め付けることによって、カラー１６を水平材３の中央部に固定する。
【００１８】
以上説明したような構成よりなる樹木用支柱を用いて樹木Ｔを支持するには、先ず、左右一対の杭部材１，１を、図１及び図２に示すように、樹木Ｔの近傍で土中に略はの字状に打ち込む。この時、各杭部材１の上端部が地面ＧＬから所要長さ突出する状態とする。この後、各杭部材１の上端部に支柱本体２を嵌挿すると共に、各支柱本体２の下端部を土中に埋め込んだ状態とし、この状態において図６の（Ａ）〜（Ｃ）に示すように支柱本体２の溝６内から六角穴付きビス１０を杭部材１に対し電動ドライバーでねじ込むことによって、杭部材１と支柱本体２とを接合する。
【００１９】
このように両杭部材１，１を先に土中に打ち込んだ後、これら杭部材１，１の上端部に両支柱本体２，２を夫々嵌合してビス１０止めすることにより、杭部材１，１に支柱本体２，２を接続するから、打ち込み作業が簡単且つ容易となる。また、樹木の種類や地盤の硬さなどによって支柱本体２の高さを所望に調整することができると共に、その調整作業を容易に行なうことができる。
【００２０】
上記のようにして左右両杭部材１，１の上端部に左右両支柱本体２，２を夫々接続したならば、両支柱本体２，２の上端部同士を、水平材３によって、図５の（Ａ）〜（Ｃ）により説明したような方法で連結固定する。こうして水平材３により両支柱本体２，２の上端部同士を連結固定した後、この水平材３の中央部にカラー１６を取り付ける。尚、カラー１６は、予め水平材３の中央部に取り付けておいてもよい。
【００２１】
しかして、水平材３に取り付けたカラー１６の係合部１８の凹面部１８ａを、樹木Ｔの外周面部に図１０に示すような状態に係合させ、この状態で縛り紐４を水平材３から樹木Ｔに亘って架け渡し、この縛り紐４によって、カラー１６を介して水平材３を樹木Ｔに縛りつける。縛り紐４は、図９の（Ａ），（Ｂ）及び図１０に示すようにカラー本体１７の外周面部に形成されている係合溝２０に係合することによって、縛り紐４がカラー１６の表面部から滑るなどして外れるようなことがなく、このカラー１６を縛り紐４によって樹木Ｔに対し長期間にわたり確実に縛りつけておくことができる。
【００２２】
また、カラー１６を水平材３に取り付けることによって水平材３が樹木Ｔに直接当たらないため、真夏時等において加熱された水平材３によって樹木Ｔが焼けるようなことがなくなる。しかも、このカラー１６は、樹木Ｔの外周面部に対応する凹面状の係合部１８を有するから、カラー１６を介して水平材３を樹木Ｔに的確に当て付けることができ、それよって樹木Ｔをより安定状態に支持することができる。
【００２３】
このような樹木用支柱によると、各杭部材１が鋼材で形成され、各支柱本体２及び水平材３が夫々アルミニウム材で形成されていて、腐食し難いから、樹木Ｔがある程度成長するまでの長期間、支柱としての機能を維持した状態で使用することができる。尚、この実施形態では、支柱本体２及び水平材３をアルミニウム材で形成しているが、これらをステンレスで形成してもよい。また、杭部材１もステンレスで形成することができる。
【００２４】
【発明の効果】
請求項１に係る発明の樹木用支柱は、樹木の近傍で土中に打ち込まれる左右一対の金属製杭部材と、土中に打ち込まれた両杭部材の夫々上端部に伸縮調整可能に接続される左右一対の金属製支柱本体と、両支柱本体の上端部同士をつなぐ金属製水平材とからなり、水平材の中央部を縛り紐によって樹木に縛りつけるようにしたもので、従来の木製支柱のように長期間使用しても腐ることがないため、防腐剤を塗布することがなく、従って防腐剤を使用した従来の樹木用支柱の焼却時における有毒ガス発生の問題がない。
【００２５】
また、この発明の樹木用支柱は、従来の樹木用支柱のように支柱部材全体を土中に打ち込むものではなく、杭部材を土中に打ち込んで、この杭部材の上端部に支柱本体を接続するようになっているから、打ち込み作業が簡単、容易となる。また、樹木の種類や地盤の硬さなどによって支柱本体の高さを所望に調整することができると共に、その調整作業を容易に行なうことができる。
【００２６】
さらに、この発明の樹木用支柱は、水平材の中央部に、樹木の外周面部に係合可能な凹面状の係合部を備えたカラーを外嵌固定することにより、水平材が樹木に直接当たらないため、真夏時等において加熱された水平材によって樹木Ｔが焼けるようなことがなくなる。またカラーは、樹木の外周面部に対応する凹面状の係合部を有するから、カラーを介して水平材を樹木に的確に当て付けることができ、それよって樹木をより安定状態に支持することができる。
【００２７】
さらにまた、支柱本体および水平材が、外周面の直径方向両側対称位置に溝を全長に亘って形成すると共に両溝の間に杭部材を挿通案内する挿通案内路を全長に亘って形成した同一断面形状の中空状のアルミ押し出し型材からなるもので、支柱本体とこれの挿通案内路に挿入された杭部材とを連結するにあたり、支柱本体の片方の溝からねじ込まれるねじ具によって杭部材を支柱本体に押し付け固定するようになっているから、杭部材と支柱本体とを任意の位置で簡単容易に連結固定でき、土中に打ち込まれた杭部材の上端部に支柱本体を伸縮調整可能に接続することができると共に、ビスの頭が支柱本体の溝内に埋没されるので、体裁が良く、美観を損なうことがない。
【００２８】
請求項２に係る発明のように、カラーの外周面部に、水平材と樹木とに亘って架け渡される縛り紐を係合させる係合溝を形成することにより、縛り紐がカラーの表面部から滑るなどして外れるようなことがなく、従ってカラーを縛り紐によって樹木に対し確実に縛りつけておくことができる。
【００２９】
請求項３に係る発明によれば、水平材の片方のリップ付き溝内に、この溝内でねじの緩み方向には回転するが、締め付け方向には回転しないようなナットを挿入配置し、このナットに、支柱本体の一方の溝から他方の溝に亘って貫通させたボルトをねじ込むことにより、水平材を支柱本体に連結するようになっているから、ボルトをねじ込み方向に回転させれば、ナットが伴回りせず、水平材の表側からボルトによる締付け作業を簡単に行うことができる。また、ボルトの頭が支柱本体の溝内に埋没されるので、体裁が良く、美観を損なうことがない。
