Description

【０００１】
【発明の属する技術分野】
本発明は、植樹後、所定期間にわたり樹木を安定保持せしめるために使用する樹木安定装置に関する。
【０００２】
【従来の技術】
樹木を植付ける際には、強風等に耐え得るようにするため、掘削した植付け穴の底部に植樹安定装置を設置し、その上に樹木の根鉢を載置すると共に、根鉢を植樹安定装置に縛りつけ、その後、植付け穴を土により埋め戻すことが行われている。
【０００３】
このような植樹安定装置は、種々のものが公知であり、通常、金属製のフレームにより枠組形成した台座を構成しており、台座に根鉢を載置した状態でフレームに係止環を係止すると共に、該係止環に連結されたスリング等の緊締条片を根鉢の肩部に掛け渡し、これにより根鉢を台座に縛りつけている。
【０００４】
一般的に、台座は、相互に９０度に直交して井桁状に配置される第一フレームと第二フレームとから構成され、直交部分を連結固着される。尚、係止環は、第一フレーム及び第二フレームのそれぞれに外挿せしめられる矩形枠状の環状金具により構成されており、スリング等の緊締条片を該環状金具に挿通せしめると共に根鉢の肩部に掛け渡し、ウインチ等の締結手段により締結することにより、根鉢を台座に縛りつけている。
【０００５】
台座を構成する第一フレーム及び第二フレームの端部には、抵抗板が設けられており、植付け穴を埋め戻すことにより土中に埋入され、上下移動を阻止された状態で台座を安定的に固定する。
【０００６】
【発明が解決しようとする課題】
従来技術によれば、次のような種々の問題がある。
【０００７】
第一に、台座は、相互に９０度に直交して井桁状に配置した第一フレームと第二フレームを固定状態に固着する構成とされている。即ち、第一フレームと第二フレームの交差角度を変更することができない。このため、植付け穴を掘削した後、台座を穴底に設置しようとする際、穴の形状の歪み等により、井桁状の台座が穴壁に干渉するため穴に装入できないときは、改めて穴を拡大するように掘削作業を再開しなければならないという不便がある。
【０００８】
第二に、第一フレームと第二フレームをそれぞれ１本のパイプ材等により形成するときは、台座に載置された根鉢の底部にフレームが食い込み、根鉢を好適に支持できないため、第一フレームと第二フレームをそれぞれ平行な複数本のパイプ材により形成することが好ましい。この点に関して、従来においては、樹齢等による根鉢の大小に応じて、寸法を相違した小型のものから大型のものまで数種類の台座が提供されており、コスト高の要因となっている。
【０００９】
第三に、製品の梱包や運搬の便宜のためには、第一フレームと第二フレームを分解組立自在に構成することが好ましい。この場合、両フレームは、現場において井桁状に組付けられることになるが、パイプ材等から成る第一フレームと第二フレームを交差せしめた状態で連結したとき、一方のフレームが下側に位置し、他方のフレームが上側に位置するような構成においては、両フレームの上面が全体として面一状に配置されない。このため、根鉢の底面を好適に支持することができないという問題がある。
【００１０】
【課題を解決するための手段】
本発明は、その実施形態により上記課題を解決すると共に、特に、第１の発明として、根鉢を底部から側部にかけて好適に支持できると共に、根鉢に掛け渡した緊締条片を支持部材の係止部に係止した状態で締結したとき、該締結条片が緩むことなく常に緊張した状態で根鉢を保持できるように構成した植樹安定装置を提供し、また、第２の発明として、根鉢に掛け渡した緊締条片を支持部材の係止部に係止した状態で締結したとき、根鉢を底部から側部にかけて支持する湾曲部材を引き上げることにより、根鉢の底部から側部に好適に沿わしめることができるようした植樹安定装置を提供するものである。
【００１１】
そこで、本発明が第１の手段として構成したところは、枠組状のフレームを備えた台座に設けた支持手段 (18) に樹木の根鉢を載置せしめた状態で、該支持手段 (18) の係止手段 (26) に連結された緊締条片を根鉢の肩部に掛け渡すことにより該根鉢を台座に締結する植樹安定装置において、前記支持手段 (18) は、前記台座のフレームに設けられた枠部材 (21) と、該枠部材 (21) に設けられた連結環 (23) と、枠部材 (21) と連結環 (23) の間に架設された弾性変形自在な湾曲部材 (24) とから構成されており、前記枠部材 (21) は、根鉢の底部に臨む内側部 (21a) と根鉢の側部に臨む外側部 (21b) を備えており、前記連結環 (23) は、該連結環の下端部を前記枠部材 (21) の外側部 (21b) に連結軸 (22) を介して回動自在に連結されると共に、上端部に前記緊締条片を係止する係止部 (26) を備え、該連結軸 (22) と係止部 (26) の間に取付軸 (25) を設けており、前記湾曲部材 (24) は、前記枠部材 (21) の内側部 (21a) と前記連結環 (23) の取付軸 (25) との間に架設され、根鉢の底部に沿わしめられる受け部 (24a) と根鉢の側部に沿わしめられる抱持部 (24b) を備えており、根鉢の肩部に掛け渡した緊締条片を前記係止部 (26) に係止した状態で締結したとき、連結環 (23) が連結軸 (22) を介して上向き直立姿勢へと回動することにより、湾曲部材 (24) を弾性変形せしめるように構成されて成る点にある。
【００１２】
また、本発明が第２の手段として構成したところは、枠組状のフレームを備えた台座に設けた支持手段 (18) に樹木の根鉢を載置せしめた状態で、該支持手段 (18) の係止手段 (26) に連結された緊締条片を根鉢の肩部に掛け渡すことにより該根鉢を台座に締結する植樹安定装置において、前記支持手段 (18) は、前記台座のフレームに設けられた枠部材 (21) と、該枠部材 (21) に設けられた連結環 (23) と、枠部材 (21) と連結環 (23) の間に架設された弾性変形自在な湾曲部材 (24) とから構成されており、前記枠部材 (21) は、根鉢の底部に臨む内側部 (21a) と根鉢の側部に臨む外側部 (21b) を備えており、前記連結環 (23) は、該連結環の下端部を前記枠部材 (21) の外側部 (21b) に連結されると共に、該連結環の上下方向に延びる支持杆 (22a) に摺動自在なスライド部材 (25a) を介して取付軸 (25) と係止部 (26) を設けており、前記湾曲部材 (24) は、前記枠部材 (21) の内側部 (21a) と前記連結環 (23) の取付軸 (25) との間に架設され、根鉢の底部に沿わしめられる受け部 (24a) と根鉢の側部に沿わしめられる抱持部 (24b) を備えており、根鉢の肩部に掛け渡した緊締条片を前記係止部 (26) に係止した状態で締結したとき、係止部 (26) をスライド部材 (25a) を介して上方移動せしめると共に、取付軸 (25) を上方移動せしめることにより、湾曲部材 (24) を引き上げるように構成されて成る点にある。
【００１３】
【発明の実施の形態】
以下図面に基づいて本発明の好ましい実施形態を詳述する。
【００１４】
（台座におけるフレームの構成）
図１ないし図３に示すように、植樹安定装置を構成する台座１は、相互に交差して配置される第一フレーム２と第二フレーム３から構成され、第一フレーム２及び第二フレーム３は、それぞれ平行な複数本の単位フレームから構成されている。図例の場合、それぞれ２本の単位フレームを備えており、第一フレーム２は単位フレーム２ａ、２ｂにより構成され、第二フレーム３は単位フレーム３ａ、３ｂにより構成されている。尚、図例において、単位フレームは、丸パイプにより構成されているが、角パイプ、その他により構成しても良い。
【００１５】
（フレームの交差部における折曲偏位構成）
図示のように、第一フレーム２（単位フレーム２ａ、２ｂ）は、第二フレーム３に対する交差部２ｃ、２ｃから放射方向に延びる脚部２ｄ、２ｄを備え、同様に、第二フレーム３（単位フレーム３ａ、３ｂ）は、第一フレーム２に対する交差部３ｃ、３ｃから放射方向に延びる脚部３ｄ、３ｄを備えている。そこで、第一フレーム２と第二フレーム３を交差配置した状態で、それぞれの脚部２ｄ及び３ｄの上面が相互に面一となるように、交差部２ｃ、２ｃ及び３ｃ、３ｃのうち、少なくとも一方を下側に折曲偏位せしめている。図例の場合、第一フレーム２の交差部２ｃ、２ｃを単位フレームの丸パイプの直径に相当して下側に折曲偏位せしめ、これにより、第一フレーム２の交差部２ｃ、２ｃの上側に第二フレーム３の交差部３ｃ、３ｃを交差して重ね合わせたとき、両フレーム２、３の脚部２ｄ及び３ｄの上面が面一となるように構成している。然しながら、例えば、第一フレーム２の交差部２ｃ、２ｃを丸パイプの直径以上に折曲偏位せしめる場合は、第二フレーム３の交差部３ｃ、３ｃも下側に折曲偏位せしめ、全体として脚部２ｄ及び３ｄの上面が面一となるように構成すれば良い。
【００１６】
（フレームにおける単位フレームの間隔連結手段）
第一フレーム２を構成する単位フレーム２ａ、２ｂと、第一フレーム３を構成する単位フレーム３ａ、３ｂは、間隔連結手段を介して、それぞれにおける相互の間隔Ｗを変更可能となるように連結されている。即ち、図２に示すように、単位フレーム２ａ、２ｂ及び３ａ、３ｂは、それぞれにおいて相互に対向する内側部分に、伸縮自在に嵌合されたパイプ４とロッド５から構成され、パイプ４とロッド５を任意の伸縮位置において固定するセットボルトを備えた間隔連結手段６を設けている。従って、このような間隔連結手段６により、第一フレーム２の相互に連結された単位フレーム２ａ、２ｂの間隔Ｗ２と、第二フレーム３の相互に連結された単位フレーム３ａ、３ｂの間隔Ｗ３は、広狭自由に調節することができる。尚、図例の場合、間隔連結手段６は、交差部２ｃ、２ｃ及び３ｃ、３ｃに設けているが、脚部２ｄ、２ｄ及び３ｄ、３ｄに設けても良い。
【００１７】
（フレームの交差部における交差連結手段）
交差部２ｃ、２ｃ及び３ｃ、３ｃを介して交差配置された第一フレーム２及び第二フレーム３は、図１に示すように、交差連結手段７を介して、相互に交差角度を変更可能に連結されている。図例の場合、交差連結手段７は、交差部２ｃ、２ｃ及び３ｃ、３ｃを上下から挟持する上板８と下板９とから構成され、第一フレーム２と第二フレーム３を所定の交差角度θで交差せしめた状態で、両板８、９の中心部をボルト・ナット等の着脱固着手段１０により締結すると共に、両板８、９の隅部をボルト・ナット等の着脱固着手段１１により締結した構成を示している。従って、第一フレーム２と第二フレーム３は、着脱固着手段１０、１１を緩めることにより、上板８と下板９の間において交差角度θを変更することが可能であり、着脱固着手段１０、１１を締結することにより、交差角度θを固定するように上板８と下板９により挟持される。然しながら、交差連結手段７は、図示の構成に限られるものではなく、要するに、第一フレーム２と第二フレーム３を交差部分において相互に交差角度θを調節変更可能となるように連結するものであれば良い。
【００１８】
（フレームの隣り合う脚部の伸縮連結手段）
このようにして相互に交差配置され連結された第一フレーム２と第二フレーム３は、交差部２ｃ、２ｃ及び３ｃ、３ｃの周囲において、伸縮連結手段１２を介して連結されている。伸縮連結手段１２は、例えば、ターンバックルのような伸縮かつ固定自在な装置や、ダンパーのような伸縮自在な装置等から成る伸縮体１３と、伸縮体１３の両端に設けられた回動自在な連結手段１４、１４から構成されており、第一フレーム２及び第二フレーム３の取付位置に設けた取付金具１５に対して、連結手段１４を回動自在に連結せしめている。図例の場合、取付金具１５は、脚部２ｄ及び３ｄに摺動自在に外挿せしめたパイプ片にブラケットを設けた構成とされ、セットボルト（図示省略）により脚部２ｄ及び３ｄの所定位置に固定されているが、このような構成に限定されるものではない。従って、上述のように、交差連結手段７により第一フレーム２と第二フレーム３の交差角度θを変更することにより隣り合う脚部２ｄ及び３ｄの間隔が変わる場合でも、伸縮連結手段１２により脚部２ｄ及び３ｄを相互に連結できる。そして、伸縮連結手段１２は、外側（台座１の外周方向）に向けて延びる埋設板１６を設けており、後述するように台座１を植付け穴に設置した後、土砂により植付け穴を埋め戻した際、土中に埋入され、台座１を固定する。尚、図例の場合、埋設板１６は、基部１６ａと平坦部１６ｂを有する断面Ｌ形の金属板から成り、伸縮体１３に対して反転自在に取付けられている。即ち、伸縮体１３には取付金具１７が固着されており、該取付金具１７の軸部１７ａに回転自在に外挿されたスリーブ１６ｃに対して、埋設板１６の基部１６ａを固着しており、平坦部１６ｂを外側に水平姿勢となるように展開せしめた状態で、取付金具１７のストッパー１７ｂを基部１６ａに当接せしめる構成とされている。
【００１９】
（緊締条片の係止手段と根鉢の支持部材）
第一フレーム２を構成する単位フレーム２ａ、２ｂの脚部２ｄ、２ｄ、並びに第二フレーム３を構成する単位フレーム３ａ、３ｂの脚部３ｄ、３ｄには、それぞれ支持部材１８が設けられており、支持部材１８は、後述するように、根鉢を底部から側部にかけて支持する支持手段と、根鉢を締結するための緊締条片を係止せしめる係止手段として機能する。
【００２０】
図２に示すように、支持部材１８は、脚部２ｄ及び３ｄに摺動自在に外挿されセットボルト等の固定手段（図示省略）により固定された座金具１９に対して、脚部に交差する横軸となる枢軸２０を介して回動自在に軸支された枠部材２１と、枠部材２１に対して前記枢軸２０と平行な連結軸２２を介して回動自在に連結された連結環２３と、枠部材２１と連結環２３の間に架設された湾曲部材２４とから構成されている。
【００２１】
枠部材２１は、枢軸２０の近傍部から、第一及び第二フレーム２、３の中心側に向けて内側に延びる内側部２１ａと、第一及び第二フレーム２、３の中心側とは反対側に向けて延びる外側部２１ｂとを備え、内側部２１ａと外側部２１ｂを相互に上向きに屈折せしめた構成とされている。
【００２２】
連結環２３は、枠部材２１の外側部２１ｂに設けられたパイプ材から成る連結軸２２に対して回動自在に連結されると共に、連結軸２２と平行なパイプ材から成る取付軸２５を該連結環２３の横杆に回動自在に設けており、連結軸２２から第一及び第二フレーム２、３の中心側とは反対側に向けて延びる環部により緊締条片のための係止部２６を構成している。
【００２３】
湾曲部材２４は、弾性変形可能なスリングロッドから成り、枠部材２１の内側部２１ａと連結環２３の取付軸２５との間に架設され、後述するように、根鉢の底部に沿わしめられる受け部２４ａと、根鉢の側部に沿わしめられる抱持部２４ｂを形成する。図例の場合、受け部２４ａと抱持部２４ｂは、一連に湾曲せしめられた構成とされている。
【００２４】
従って、上記支持部材１８の構成を要約すると、図５（Ｂ）に示すように、支持部材１８により根鉢３６を支持する際に、枠部材２１は、内側部２１ａを根鉢３６の底部に臨ませると共に外側部２１ｂを根鉢３６の側部に臨ませる。そして、連結環２３は、下端部を前記枠部材２１の外側部２１ｂに連結軸２２を介して回動自在に連結されており、上端部に緊締条片を係止するための係止部２６を備え、連結軸２２と係止部２６の間に取付軸２５を設けている。そして、湾曲部材２４は、枠部材２１の内側部２１ａと連結環２３の取付軸２５との間に架設されている。そこで、根鉢の肩部に掛け渡した緊締条片を前記係止部２６に係止した状態で締結したとき、連結環２３が連結軸２２を介して上向き直立姿勢へと回動することにより、湾曲部材２４を弾性変形せしめるように構成されている。
【００２５】
支持部材１８は、枢軸２０を介して回動自在であり、図５（Ａ）に示すように、枠部材２１の内側部２１ａと湾曲部材２４の受け部２４ａを第一及び第二フレーム２、３の中心側（交差部）に向けて上向き傾斜せしめた姿勢においては、枠部材２１の外側部２１ｂと湾曲部材２４の抱持部２４ｂを伏臥せしめた姿勢とする。この状態から、枢軸２０を介して回動せしめることにより、図５（Ｂ）に示すように、枠部材２１の内側部２１ａと湾曲部材２４の受け部２４ａをほぼ水平とした姿勢においては、枠部材２１の外側部２１ｂと湾曲部材２４の抱持部２４ｂを起立せしめた姿勢とする。この際、枠部材２１の外側部２１ｂは、第一及び第二フレーム２、３の中心側とは反対側に向けて上向き傾斜する姿勢で起立するが、連結軸２２を介して連結環２３を上向きに直立するように回動せしめると、スプリングロッドから成る湾曲部材２４は、枠部材２１の内側部２１ａと連結環２３の取付軸２５との間において、湾曲を強めるように弾性変形する。
【００２６】
（抵抗板）
第一フレーム２を構成する単位フレーム２ａ、２ｂの脚部２ｄと、第二フレーム３を構成する単位フレーム３ａ、３ｂの脚部３ｄは、それぞれの端部に、平行配置された単位フレーム２ａ、２ｂ及び３ａ、３ｂの離反方向に延びる翼状の抵抗板２７を設け、該抵抗板２７を脚部２ｄ及び３ｄよりも下位（好ましくは交差部のうち下側に位置する交差部２ｃよりも下位）に配置しており、各抵抗板２７を平行配置された単位フレーム２ａ、２ｂ及び３ｄ、３ｄの対向方向に反転自在とする反転手段２８と、該抵抗板２７の高さ位置を変更可能とする高さ調整手段２９を設けている。
【００２７】
図例の場合、図２に示すように、一対のパイプ片から成る取付金具３０、３０が脚部２ｄ及び３ｄに摺動自在に外挿され、セットボルト（図示省略）により固定されており、取付金具３０、３０に架設されたＵ形の支持金具３１と、基部３２ａと平坦部３２ｂを有する断面Ｌ形の回動金具３２により反転手段２８を構成している。即ち、支持金具３１の軸部３１ａに回転自在に外挿されたスリーブ３２ｃに対して回動金具３２の基部３２ａを固着しており、平坦部３２ｂを脚部２ｄ及び３ｄの離反方向に水平姿勢となるように展開せしめた状態で、支持金具３１のストッパー３１ｂを基部３２ａに当接せしめる構成とされている。
【００２８】
抵抗板２７は、回動金具３２の平坦部３２ｂの下方位置において、上下間隔を調節可能とするボルト・ナット等から成る高さ調整手段２９を介して連結されている。従って、回動金具３２と抵抗板２７は、図２に示すような展開状態から、回動金具３２のスリーブ３２ｃを回動せしめることにより、図３に示すような反転位置に折り畳むことが可能である。
【００２９】
（台座のジョイント用コネクタ）
第一フレーム２の脚部２ｄ、２ｄと、第二フレーム３の脚部３ｄ、３ｄには、複数の台座１を相互に連結可能とするジョイント用コネクタ３３を設けることができる。図例の場合、ジョイント用コネクタ３３は、図２に示すようなパイプ片から構成され、隣り合って敷設される台座１、１のうち、一方の台座１のジョイント用コネクタ３３に他方の台座１の脚部２ｄ又は３ｄを嵌挿せしめ、セットボルト等（図示省略）の固定手段により固着する構成とされている。このようなジョイント用コネクタ３３は、図２に示すように抵抗板２７のための取付金具３０に固着することにより設けても良く、或いは、脚部２ｄ及び３ｄ又は抵抗板２７に設けても良い。
【００３０】
（実施形態に基づく作用及び効果）
上記実施形態によれば、台座１を構成する第一フレーム２及び第二フレーム３は、図３に示すように、分解した状態で梱包され、保管又は運搬することができる。この際、抵抗板２７を反転することにより折り畳み、第一フレーム２と第二フレーム３を平行に重ね合わせることができるので、嵩張ることなくコンパクトである。尚、交差連結手段７及び伸縮連結手段１２は、第一フレーム２及び第二フレーム３から分解し、同梱又は別梱することができる。
【００３１】
台座１を植樹安定装置として実施するに際しては、図１に示すように、第一フレーム２と第二フレーム３を交差状に組立すると共に、交差連結手段７により連結固着することにより組付ける。同時に、第一フレーム２及び第二フレーム３の隣り合う脚部２ｄ及び３ｄを伸縮連結手段１２により連結し、更に、埋設板１６及び抵抗板２７を展開せしめた状態で、台座１を完成する。この際、単位フレーム２ａ、２ｂ及び３ａ、３ｂのそれぞれは、間隔連結手段６を介して、脚部２ｄ、２ｄ及び３ｄ、３ｄの間隔Ｗ２及びＷ３を変更可能とされているので、随時、間隔を調節すれば良い。即ち、植樹を目的とする樹木における樹齢等による根鉢の大小に応じて、脚部２ｄ、２ｄ及び３ｄ、３ｄの間隔Ｗ２及びＷ３を設定することにより、１台の台座１により根鉢の大きさに自在に対応せしめることができる。そして、第一フレーム２の交差部２ｃ、２ｃの上側に第二フレーム３の交差部３ｃ、３ｃを交差して重ね合わせ、交差連結手段７により連結した状態で、交差部２ｃ、２ｃに設けた折曲偏位の手段により、両フレーム２、３の脚部２ｄ及び３ｄは、上面を面一とする。
【００３２】
図６（Ａ）に示すように、地面に植樹を行う場合は、地面に植付け穴３４が掘削され、穴底に台座１を設置されるが、穴の形状の歪み等により、第一フレーム２と第二フレーム３を交差せしめた台座１の端部が干渉するような穴壁３４ａが存在する場合は、交差連結手段７の着脱固着手段１０、１１を緩め、図示の鎖線から実線に示すように第一フレーム２と第二フレーム３の交差角度θを変更せしめた後、交差連結手段７の着脱固着手段１０、１１を締結することにより、台座１を穴壁３４ａに干渉しない状態で穴底に設置することができる。従って、従来のように、改めて穴を拡大するように掘削作業を再開する必要はない。
【００３３】
図６（Ｂ）に示すように、例えば、屋上緑化等の目的で、比較的浅い土床に樹木を植樹する場合は、複数の台座１、１を相互に連結せしめた状態で敷設し、台座の全体的な重量増により樹木の支持を行わしめる。この点に関して、上記実施形態によれば、隣り合って敷設される台座１、１のうち、一方の台座１のジョイント用コネクタ３３に他方の台座１の脚部２ｄ又は３ｄを嵌挿せしめ、セットボルト等の固定手段により固着することができる。この際、図２に示すように、ジョイント用コネクタ３３を抵抗板２７の取付金具３０に設けた場合、一方の台座１のジョイント用コネクタ３３、３３の間隔と、他方の台座１の脚部２ｄ、２ｄ及び３ｄ、３ｄの間隔が合致せず、そのままでは脚部２ｄ、２ｄ及び３ｄ、３ｄをジョイント用コネクタ３３、３３に挿入できないことになるが、上述のように、単位フレーム２ａ、２ｂ及び３ａ、３ｂのそれぞれは、間隔連結手段６を介して、脚部２ｄ、２ｄ及び３ｄ、３ｄの間隔Ｗ２及びＷ３を変更することができるので、随時、間隔を調節することにより、一方の台座１のジョイント用コネクタ３３、３３に対して、他方の台座１の脚部２ｄ、２ｄ及び３ｄ、３ｄを挿着することができる。
【００３４】
植付け穴の穴底が起伏を有すると、台座を水平に設置することが困難となるため、植付け穴は、穴底が平坦な水平面となるように掘削しなければならない。この点に関して、上記実施形態によれば、図４に示すように、植付け穴３４の穴底が起伏を有する場合でも、高さ調整手段２９により抵抗板２７の高さ位置を調節することができるので、これにより第一フレーム２及び第二フレーム３を水平に設置せしめることが可能であり、従来のように特に穴底が水平面となるような掘削作業を必要とする煩雑はない。
【００３５】
このようにして植付け穴３４に設置された台座１は、上述のように間隔Ｗ２及びＷ３を調整された単位フレーム２ａ、２ｂ及び３ａ、３ｂにおいて、交差部分の周囲に支持部材１８を配置している。即ち、図例の場合、８個の支持部材１８が周方向に配置されている。従って、植樹すべき樹木３５の根鉢３６を台座１に載置すると、根鉢３６は、これらの支持部材１８により好適に支持される。
【００３６】
支持部材１８は、根鉢３６を載置せしめる前においては、図５（Ａ）に示すように、枠部材２１の内側部２１ａと湾曲部材２４の受け部２４ａを第一及び第二フレーム２、３の中心側（交差部）に向けて上向き傾斜せしめ、枠部材２１の外側部２１ｂと湾曲部材２４の抱持部２４ｂを伏臥せしめた姿勢とされている。この際、図示矢印Ｆで示すように、座金具１９はフレーム２、３の長手方向に摺動自在であり、支持部材１８の位置を自由に調整できる。
【００３７】
そこで、根鉢３６を載置すると、支持部材１８は、根鉢３６の重量により、枢軸２０を介して自動的に回動せしめられる。即ち、上向き傾斜姿勢とされた枠部材２１の内側部２１ａ並びに湾曲部材２４の受け部２４ａが、根鉢３６の底部を受けることにより下方に向けて回動され、図５（Ｂ）に示すように、ほぼ水平姿勢とされ、枠部材２１の外側部２１ｂ並びに湾曲部材２４の抱持部２４ｂを起立せしめる。この際、枠部材２１は、根鉢３６の荷重を受けることにより、内側部２１ａの先端部２１ｘをフレーム２、３に圧接せしめるので、座金具１９の摺動を阻止し、当該位置に支持部材１８を位置決めする。
【００３８】
従って、自立せしめられた枠部材２１の外側部２１ｂにおける連結環２３の係止部２６に対して、スリング等の緊締条片３７ａを容易に挿通せしめることができる。尚、緊締条片３７ａは、樹木３５の外周に環状に設けた緊締条片３７ｂを介して根鉢３６の肩部に掛け渡された後、ウインチ等の締結手段により締結され、根鉢３６を台座１に縛りつける。
【００３９】
この際、緊締条片３７ａの引き上げ方向の力により、連結環２３は、連結軸２２を介して、図５（Ｂ）に示すように、鎖線で示す傾斜姿勢から実線で示す上向き直立姿勢へと回動せしめられ、これにより、スプリングロッドから成る湾曲部材２４が湾曲を強めるように弾性変形する。即ち、このように弾性変形せしめられた湾曲部材２４は、実線で示す上向き直立姿勢から鎖線で示す傾斜姿勢に向けて復元しようとするスプリング力を蓄積する。尚、緊締条片３７ａの引き上げ力により、前述したようなフレーム２、３に対する枠部材２１の先端部２１ｘの圧接力が益々増すことになる。
【００４０】
その後、植付け穴３４を土砂により埋め戻し、作業を完了するが、この状態において、根鉢３６は、台座１の交差部分の周囲に配置された支持部材１８により好適に支持されている。特に、根鉢３６の底部は、支持部材１８の受け部２４ａにより支承され、根鉢３６の側部は、支持部材１８の抱持部２４ｂにより抱持されており、このように根鉢３６は、底部から側部にかけて支持部材１８により直接に支持されている。従って、時間の経過や、雨水その他の天候の影響等により、植付け穴３４の内部において土砂が固く締まるような場合でも、それにより生じる土痩せとは無関係に、常に根鉢３６を良好に支持せしめた状態を持続することができる。
【００４１】
ところで、締め付けた緊締条片３７ａが、その後、万一、緩むような現象を生じた場合においても、緊締条片３７ａを連結せしめた連結環２３には、湾曲部材２４により蓄積されたスプリング力が作用している。即ち、緊締条片３７ａが緩むとき、連結環２３は、図５（Ｂ）に実線で示す上向き直立姿勢から鎖線で示す傾斜姿勢に至るまで湾曲部材２４の復元スプリング力を作用せしめられているので、これにより、緊締条片３７ａの緩みを吸収し、常に緊締条片３７ａを緊張した状態のまま維持せしめることができる。

（交差連結手段の別の実施形態）
本発明に係る交差連結手段７の別の実施形態を図７に示している。同図において、第一フレーム２及び第二フレーム３を構成するそれぞれの単位フレーム２ａ、２ｂ及び３ａ、３ｂは、それぞれの間隔Ｗ２及びＷ３を変更できないように固定した状態で連結されている。連結方法は問わないが、図例の場合、単位フレーム間に架設した連結パイプ３８を溶接している。そこで、第一フレーム２は、交差部２ｃ、２ｃを第一連結板３９により連結され、第二フレーム３は、交差部３ｃ、３ｃを第二連結板４０により連結されており、第一連結板３９の上に第二連結板４０を重ね合わせた状態で、相互に回動自在かつ固定自在となるように交差連結手段７により固着されている。
【００４３】
交差連結手段７は、第一連結板３９と第二連結板４０のほぼ中央部を貫通して着脱自在に固着するボルト・ナットから成る軸手段４１と、第二連結板４０に形成されたガイド孔４２と、第一連結板３９から起立してガイド孔４２を挿通するボルト・ナットから成る案内固定手段４３とから構成されている。前記ガイド孔４２は、軸手段４１を中心として円弧を描く細長い孔とされており、従って、第一連結板３９と第二連結板４０は、相互に軸手段４１の軸回りに回動自在であり、その際、案内固定手段４３がガイド孔４２に沿って移動し、これにより第一フレーム２と第二フレーム３の交差角度θを自在に変更する。そして、交差角度θが設定された後、軸手段４１及び／又は案内固定手段４３のボルト・ナットを締着すれば、第一連結板３９と第二連結板４０が回動不能に固着される。尚、これらのボルト・ナットを取外すと、第一連結板３９と第二連結板４０が相互に離脱され、第一フレーム２と第二フレーム３を分解できる点は、図３に示した実施形態と同様である。
【００４４】
（支持部材の別の実施形態）
本発明に係る支持部材１８の別の実施形態を図７及び図８に示している。支持部材１８は、枢軸２０を備えた枠部材２１と、該枠部材２１に対して前記枢軸２０と平行な連結軸２２を介して回動自在に連結された連結環２３と、枠部材２１と連結環２３の間に架設された湾曲部材２４とから構成されており、このような基本的な構成は、上述した実施形態における支持部材１８と同様である。
【００４５】
図７に示すように、枠部材２１は、枢軸２０をフレームの脚部２ｄ、２ｄ（３ｄ、３ｄ）の下側を横断するように配置せしめており、枢軸２０の両端部から、第一フレーム２、３の中心側となる内側に向けて脚部２ｄ（３ｄ）の上方に延びる内側部２１ａと、前記中心側とは反対側に向けて脚部２ｄ（３ｄ）の上方に延びる外側部２１ｂとを備え、内側部２１ａと外側部２１ｂを相互に上向きに屈折せしめた構成とされている。
【００４６】
連結環２３は、枠部材２１の外側部２１ｂに回動自在に連結されたパイプ材から成る連結軸２２と、該連結軸２２の両端近傍に交差して延設された平行な一対の支持杆２２ａ、２２ａから構成されており、支持杆２２ａ、２２ａに摺動自在に外挿せしめたパイプ材から成るスライド部材２５ａ、２５ａを相互に取付軸２５により連結せしめている。更に、一対のスライド部材２５ａ、２５ａに架設され回動自在に軸支されたロッドにより、緊締条片のための係止部２６が構成されている。
【００４７】
湾曲部材２４は、枠部材２１の内側部２１ａと連結環２３の取付軸２５との間に架設され、後述するように、根鉢の底部に沿わしめられる受け部２４ａと、根鉢の側部に沿わしめられる抱持部２４ｂを、一連に湾曲せしめられた構成とされており、好ましくは、図７に示すように、取付軸２５に対して折曲ループ部により形成された長孔２４ｃを介して連結されている。
【００４８】
支持部材１８は、図８（Ａ）に示すように、枢軸２０をフレーム２、３の下側に位置せしめ、枠部材２１の先端部２１ｘ及び連結軸２２をフレーム２、３の上側に位置せしめられており、湾曲部材２４と共に連結環２３を伏臥せしめた状態において、図示矢印Ｆで示すように、フレーム２、３の長手方向に摺動自在とされている。従って、支持部材１８の位置は、自由に調整可能である。
【００４９】
支持部材１８をフレーム２、３の所定位置に設置した状態で、根鉢３６を載置すると、内側に向けて上向き傾斜姿勢とされていた枠部材２１の内側部２１ａと、湾曲部材２４の受け部２４ａが、図８（Ｂ）に示すように、下向きに回動せしめられ、内側部２１ａの先端部２１ｘと枢軸２０によりフレーム２、３を上下からクランプし固定するので、支持部材１８の摺動を阻止し、当該位置に強固に固定する。
【００５０】
そこで、連結環２３の係止部２６に挿通せしめたスリング等の緊締条片３７ａを引き上げると、連結環２３が連結軸２２を介して回動しつつ起立するだけでなく、図８（Ｂ）において鎖線から実線に示すように、係止部２６の引き上げに伴い、スライド部材２５ａを支持杆２２ａに沿って上方に移動せしめ、同時に上方移動する取付軸２５により湾曲部材２４を引き上げるので、湾曲部材２４の抱持部２４ｂにより根鉢３６の側面を好適に保持することが可能になる。
【００５１】
従って、この別の実施形態に係る支持部材１８の構成を要約すると、図８（Ｂ）に示すように、支持部材１８により根鉢３６を支持する際に、枠部材２１は、内側部２１ａを根鉢３６の底部に臨ませると共に外側部２１ｂを根鉢３６の側部に臨ませる。そして、連結環２３は、下端部を前記枠部材２１の外側部２１ｂに連結されると共に、該連結環の上下方向に延びる支持杆２２ａに摺動自在なスライド部材２５ａを介して取付軸２５と係止部２６を設けている。そして、湾曲部材２４は、前記枠部材２１の内側部２１ａと前記連結環２３の取付軸２５との間に架設されている。そこで、根鉢の肩部に掛け渡した緊締条片を前記係止部２６に係止した状態で締結したとき、係止部２６をスライド部材２５ａを介して上方移動せしめると共に、取付軸２５を上方移動せしめることにより、湾曲部材２４を引き上げるように構成されている。
【００５２】
【発明の効果】
請求項１に記載の本発明によれば、支持部材１８により根鉢３６を支持する際に、枠部材２１は、内側部２１ａを根鉢３６の底部に臨ませると共に外側部２１ｂを根鉢３６の側部に臨ませる。そして、連結環２３は、下端部を前記枠部材２１の外側部２１ｂに連結軸２２を介して回動自在に連結されており、上端部に緊締条片を係止するための係止部２６を備え、連結軸２２と係止部２６の間に取付軸２５を設けている。そして、湾曲部材２４は、枠部材２１の内側部２１ａと連結環２３の取付軸２５との間に架設されている。そこで、根鉢の肩部に掛け渡した緊締条片を前記係止部２６に係止した状態で締結したとき、連結環２３が連結軸２２を介して上向き直立姿勢へと回動することにより、湾曲部材２４を弾性変形せしめるように構成されている。

【００５４】
そして、緊締条片３７ａの引き上げ方向の力により、連結環２３は、連結軸２２を介して上向き直立姿勢へと回動せしめられ、これにより、スプリングロッドから成る湾曲部材２４が湾曲を強めるように弾性変形し、スプリング力を蓄積する。このため、締め付けた緊締条片３７ａが、その後、万一、緩むような現象を生じた場合においても、緊締条片３７ａを連結せしめた連結環２３には、湾曲部材２４により蓄積されたスプリング力が作用しているので、緊締条片３７ａの緩みを吸収し、常に緊締条片３７ａを緊張した状態に維持できるという効果がある。
【００５５】
また、請求項２に記載の本発明によれば、支持部材１８により根鉢３６を支持する際に、枠部材２１は、内側部２１ａを根鉢３６の底部に臨ませると共に外側部２１ｂを根鉢３６の側部に臨ませる。そして、連結環２３は、下端部を前記枠部材２１の外側部２１ｂに連結されると共に、該連結環の上下方向に延びる支持杆２２ａに摺動自在なスライド部材２５ａを介して取付軸２５と係止部２６を設けている。そして、湾曲部材２４は、前記枠部材２１の内側部２１ａと前記連結環２３の取付軸２５との間に架設されている。そこで、根鉢の肩部に掛け渡した緊締条片を前記係止部２６に係止した状態で締結したとき、係止部２６をスライド部材２５ａを介して上方移動せしめると共に、取付軸２５を上方移動せしめることにより、湾曲部材２４を引き上げるように構成されている。

[0003]
Various types of tree planting stabilizers are known, and usually constitute a pedestal formed by a metal frame, and a locking ring is engaged with the frame with a root pot placed on the pedestal. At the same time, a tightening strip such as a sling connected to the locking ring is hung over the shoulder of the root pot, thereby binding the root pot to the pedestal.
[0004]
In general, the pedestal is composed of a first frame and a second frame which are arranged in a cross pattern perpendicular to each other by 90 degrees, and the orthogonal portions are connected and fixed. The locking ring is constituted by a rectangular frame-shaped annular metal fitting that is externally inserted into each of the first frame and the second frame, and a fastening strip such as a sling is inserted through the annular metal fitting and the root pot The root pot is tied to the pedestal by being hung on the shoulder and fastened by a fastening means such as a winch.

(Operations and effects based on the embodiment)
According to the said embodiment, as shown in FIG. 3, the 1st flame | frame 2 and the 2nd flame | frame 3 which comprise the base 1 are packed in the decomposed | disassembled state, and can be stored or conveyed. At this time, since the resistance plate 27 can be folded by being inverted and the first frame 2 and the second frame 3 can be overlapped in parallel, it is compact without being bulky. In addition, the cross connection means 7 and the expansion / contraction connection means 12 can be disassembled from the first frame 2 and the second frame 3 and bundled or separately packaged.
[0031]
When the pedestal 1 is implemented as a planting stabilization device, as shown in FIG. 1, the first frame 2 and the second frame 3 are assembled in a cross shape, and are assembled by being connected and fixed by the cross connection means 7. At the same time, the legs 2d and 3d adjacent to each other of the first frame 2 and the second frame 3 are connected by the expansion / contraction means 12, and the pedestal 1 is completed with the embedded plate 16 and the resistance plate 27 deployed. At this time, each of the unit frames 2a, 2b, 3a, and 3b can change the intervals W2 and W3 of the leg portions 2d, 2d, 3d, and 3d via the interval connecting means 6. You can adjust. That is, the size of the root pot is set by one pedestal 1 by setting the distances W2 and W3 of the legs 2d, 2d and 3d, 3d according to the size of the root pot depending on the age of the tree intended for tree planting. It can be freely adapted to the height. Then, the intersections 3c and 3c of the second frame 3 are crossed and overlapped on the upper side of the intersections 2c and 2c of the first frame 2, and are provided at the intersections 2c and 2c in a state of being connected by the cross-connecting means 7. By the means of bending deflection, the leg portions 2d and 3d of both the frames 2 and 3 are flush with each other.
[0032]
As shown in FIG. 6A, when tree planting is performed on the ground, the planting hole 34 is excavated in the ground and the pedestal 1 is installed at the bottom of the hole. If there is a hole wall 34a that interferes with the end of the pedestal 1 that intersects the second frame 3, the attachment / detachment fixing means 10 and 11 of the cross connection means 7 are loosened, as shown by the solid line from the chain line in the figure. After the crossing angle θ between the first frame 2 and the second frame 3 is changed, the attachment / detachment fixing means 10 and 11 of the cross connection means 7 are fastened so that the base 1 does not interfere with the hole wall 34a. Can be installed. Therefore, unlike the prior art, there is no need to resume the excavation work so as to enlarge the hole again.
[0033]
As shown in FIG. 6 (B), for example, when planting trees on a relatively shallow floor for the purpose of rooftop greening or the like, a plurality of pedestals 1 and 1 are laid together and connected to each other. The tree will be supported by the overall weight increase. In this regard, according to the above-described embodiment, of the bases 1 and 1 laid adjacent to each other, the leg 2d or 3d of the other base 1 is fitted into the joint connector 33 of the base 1 and the set It can be fixed by fixing means such as bolts. At this time, as shown in FIG. 2, when the joint connector 33 is provided on the mounting bracket 30 of the resistance plate 27, the distance between the joint connectors 33, 33 of one pedestal 1 and the leg portion 2 d of the other pedestal 1. 2d and 3d and 3d do not match and the legs 2d, 2d and 3d and 3d cannot be inserted into the joint connectors 33 and 33 as they are, but as described above, the unit frames 2a, 2b and Each of 3a and 3b can change the intervals W2 and W3 of the leg portions 2d, 2d and 3d and 3d via the interval connecting means 6, so that by adjusting the interval as needed, one base 1 The leg portions 2d, 2d and 3d, 3d of the other pedestal 1 can be inserted into the joint connectors 33, 33.
[0034]
If the bottom of the planting hole has undulations, it is difficult to install the pedestal horizontally. Therefore, the planting hole must be drilled so that the bottom of the planting hole becomes a flat horizontal surface. In this regard, according to the above embodiment, as shown in FIG. 4, even when the bottom of the planting hole 34 has undulations, the height position of the resistance plate 27 can be adjusted by the height adjusting means 29. As a result, the first frame 2 and the second frame 3 can be installed horizontally, and there is no need for excavation work in which the hole bottom becomes a horizontal plane as in the conventional case.
[0035]
The pedestal 1 thus installed in the planting hole 34 has the support members 18 arranged around the intersecting portions in the unit frames 2a, 2b, 3a, and 3b adjusted in the intervals W2 and W3 as described above. Yes. That is, in the case of the illustrated example, eight support members 18 are arranged in the circumferential direction. Accordingly, when the root pot 36 of the tree 35 to be planted is placed on the pedestal 1, the root pot 36 is suitably supported by these support members 18.
[0036]
Before the root pot 36 is placed on the support member 18, the inner portion 21 a of the frame member 21 and the receiving portion 24 a of the bending member 24 are connected to the first and second frames 2, as shown in FIG. 3 is inclined upward toward the center side (intersection), and the outer portion 21b of the frame member 21 and the holding portion 24b of the bending member 24 are in a prone posture. At this time, as indicated by an arrow F in the figure, the metal fitting 19 is slidable in the longitudinal direction of the frames 2 and 3 and the position of the support member 18 can be freely adjusted.
[0037]
Therefore, when the root pot 36 is placed, the support member 18 is automatically rotated via the pivot 20 by the weight of the root pot 36. That is, the inner portion 21a of the frame member 21 that is inclined upward and the receiving portion 24a of the bending member 24 are rotated downward by receiving the bottom portion of the root pot 36, as shown in FIG. Furthermore, the posture is almost horizontal, and the outer portion 21b of the frame member 21 and the holding portion 24b of the bending member 24 are erected. At this time, since the frame member 21 receives the load of the root pot 36, the tip portion 21x of the inner portion 21a is brought into pressure contact with the frames 2 and 3, so that the seat bracket 19 is prevented from sliding, and the support member is placed at the position. 18 is positioned.
[0038]
Therefore, the fastening strip 37a such as a sling can be easily inserted into the locking portion 26 of the connecting ring 23 in the outer side portion 21b of the frame member 21 that is self-supported. The tightening strip 37a is looped over the shoulder of the root pot 36 via a tightening strip 37b provided annularly on the outer periphery of the tree 35, and then fastened by a fastening means such as a winch. Tie to pedestal 1.
[0039]
At this time, due to the force in the pulling-up direction of the fastening strip 37a, the connecting ring 23 is changed from the inclined posture shown by the chain line to the upward standing posture shown by the solid line through the connecting shaft 22 as shown in FIG. As a result, the bending member 24 made of a spring rod is elastically deformed to increase the bending. In other words, the bending member 24 elastically deformed in this manner accumulates a spring force that is to be restored from the upward standing posture shown by the solid line toward the inclined posture shown by the chain line. Note that the pulling force of the tightening strip 37a further increases the pressure contact force of the tip 21x of the frame member 21 to the frames 2 and 3 as described above.
[0040]
Thereafter, the planting hole 34 is backfilled with earth and sand, and the operation is completed. In this state, the root pot 36 is suitably supported by the support member 18 arranged around the intersection of the base 1. In particular, the bottom part of the root pot 36 is supported by the receiving part 24a of the support member 18, and the side part of the root pot 36 is held by the holding part 24b of the support member 18. Thus, the root pot 36 is It is directly supported by the support member 18 from the bottom to the side. Therefore, even when the earth and sand are firmly tightened inside the planting hole 34 due to the passage of time, rain water, or other weather, the root pot 36 is always well supported regardless of the earthiness caused by it. Can maintain the state.
[0041]
By the way, even if the tightened tightening strip 37a is loosened after that, the spring force accumulated by the bending member 24 is applied to the connecting ring 23 to which the tightening strip 37a is coupled. It is working. That is, when the tightening strip 37a is loosened, the connecting ring 23 is applied with the restoring spring force of the bending member 24 from the upward standing posture shown by the solid line to the inclined posture shown by the chain line in FIG. As a result, the looseness of the tightening strip 37a can be absorbed, and the tightening strip 37a can always be maintained in a tensioned state.
