Description

【０００１】
【発明の属する技術分野】
本発明は回動により開閉扉するドアを、その下端縁と床面との間に挟入することで所望の開扉状態に保持するため用いられるドアストッパーに関する。
【０００２】
【従来の技術】
従来、ドアを開扉状態に保持するには、床面とドアの下端縁との間に楔状としたドアストッパーを圧入するようにしているが、これでは上記床面とドアとの隙間寸法に応じて、少なくとも大小二様のドアストッパーを入手しておかなければならない。
そこで上記の欠陥を解消するため、既に図８に示す通り楔状とした下積ドアストッパーＡと上積ドアストッパーＢとを用意して、これらは前記の隙間寸法が比較的小さいときは、何れをも各別に使用することができるようにし、当該隙間寸法が大きいときは、下積ドアストッパーＡの基端突起ａに、上積ドアストッパーＢの基端凹所ｂを嵌合することで、当該両者を重積固定状態としてドアストッパーとしての使用を可能としたものが提案されている。
また、図９に開示の提案によるときは、楔状である第１、第２ドアストッパーＣ、Ｄをその各基端縁にあってヒンジｄによって枢着したもので、同図（Ａ）のように第１、第２ドアストッパーＣ、Ｄを一直線上に開成状態とすることで、前記隙間寸法の小さい場合に対処し、同図（Ｂ）の如く第１、第２ドアストッパーＣ、Ｄを、夫々の第１、第２載置底面ｅ、ｆが相当接されるように折り畳むことで、大きな隙間寸法に対応させるようにしている。
【０００３】
【発明が解決しようとする課題】
上記した従来例は、夫々従前の単なる楔状としたものに比し使い勝手を改善することができるが、図８の場合には、基端突起ａと基端凹所ｂとの嵌合を離脱して、下積ドアストッパーＡと上積ドアストッパーＢとが分離されていることから、その一方を紛失したり、しまい忘れたりしてしまった際には、当該急場を凌ぐことができなくなるといった難点がある。
また図９のドアストッパーによるときは、小さい隙間寸法の場合にあって同図（Ａ）のように、第１、第２ドアストッパーＣ、Ｄが直線状に展開されることになるため、不使用状態となる一方の第２ストッパーＤ等がドアから大きく延出してしまい、このため人や運搬車等の通行を阻害するといったことが生じ得ることとなる。
【０００４】
本発明は上記の欠陥を解消しようとするもので、請求項１によるときは、第１分断ドア止め載置体と第２分断ドア止め載置体とを直列状態となるように、連枢保持機構によって連枢させておき、当該直列状態下にあって床面とドアの隙間が小さいときに対処させるようにすると共に、当該隙間が大きい場合には、直列状態であった上記の第２分断ドア止め載置体を昇動変移させることで、その第２載置底面を第１分断ドア止め載置体の第１ドア止め傾斜上面に載置させてしまうのであり、もちろん第１分断ドア止め載置体の低位置状態と高位置状態とを、上記した連枢保持機構により保持可能とするのである。
【０００５】
かくして、請求項１によるときは、第２分断ドア止め載置体が低位置にあるときには、直列構成としたことから低位置状態では嵩張ることなく小型化を可能とし、かつ高位置状態では、短い長さの第２分断ドア止め載置体を、これまた短い長さの第１分断ドア止め載置体に載置させてしまうので、全体として短い寸法に納まり、これより歩行の邪魔になることもなく、かつ収納に際しても至便となし、かつ第１、第２分断ドア止め載置体の肉厚を加算した充分な高さ寸法を確保させ得るようにし、しかも連枢保持機構自体の構成や組立作業の簡素化と能率化をも実現しようとするのが、その目的である。
【０００６】
さらに請求項２にあっては、上記請求項１における連枢保持機構の一実施態様を明示したもので、第１、第２分断ドア止め載置体の幅員方行へ回動自在に軸装の第１、第２軸ピン部と、これらの第１、第２延出端部を連設する回動アーム部とからなる連枢軸ピンを用いるだけで、第２分断ドア止め載置体の低位置そして高位置の各状態を保持できるようにしている。
【０００７】
請求項３では、前記請求項２における連枢保持機構につき、さらにその具体例を示したもので、ここではその連枢軸ピンが第１軸ピン部と一対の回動アームと、一対の対向軸杆とによってＣ字状に形成されるようにするだけでなく、上記の第１軸ピン部を第１分断ドア止め載置体の嵌入用スリットから第１軸孔に嵌合させ得るようにし、かつ上記一対の対向軸杆は第２分断ドア止め載置体の第２軸孔へ外側から嵌合可能として、その組立作業を迅速かつ容易に行い得るようにするのが、その目的である。
【０００８】
そして請求項４にあっては、前記請求項２にあって、第１、第２分断ドア止め載置体の第１、第２衝当端面を、下方へ向けてドア装入側へ近づくように傾斜するようにすることで、第１分断ドア止め載置体に対する第２分断ドア止め載置体の昇動変移なる回動操作を円滑に行い得るようにし、当該第２分断ドア止め載置体の低位置から高位置への可逆的な昇動変移を円滑に行い得るようにするのが、その目的である。
【０００９】
さらに請求項５の場合は、上記した請求項４の構成にあって、その第１、第２衝当端面が何れもフラットな傾斜平面により形成されているのに対し、相互に夫々の係合凹所を係合凸所とが嵌合状態となるようにすることで、第１、第２分断ドア止め載置体が、何れも低位置にあって床上載置状態にて連装されている際、当該連装状態の安定性が確保され、不本意に第１、第２分断ドア止め載置体の連装状態が分離されてしまうといったことなく、両者の一体性が保証されるようにしている。
【００１０】
次に請求項６における基本的構成は、請求項１の内容と同様であるが、その第１、第２衝当端面と連枢保持機構の各構成内容が以下のように相違している。
すなわち、先ず上記第１、第２衝当端面は、係嵌用突部と係嵌用凹所との嵌合構成とし、かつ連枢保持機構における連枢軸ピンを所定の連枢状態に保持自在とすることによって、第１、第２分断ドア止め載置体の連結状態を安定に確保できるようにすると共に、第１分断ドア止め載置体には、前記連枢軸ピンの第１軸ピン部が嵌合する第１軸孔だけでなく、これに狭小連通路を介して分離用軸孔をも並設しておくのである。そして上記第１軸ピン部を第１軸孔から分離用軸孔へ離脱転移させることで、第１分断ドア止め載置体と第２分断ドア止め載置体とを離脱状態として、第１分断ドア止め載置体の昇動変移による第２分断ドア止め載置体上への載置ができるようにし、かつ当該載置状態が、第１軸ピン部を分離用軸孔から第１軸孔へ復動することで、安定状態が確保できるようにしている。
そして請求項７では上記の請求項６において、その上記した分離用軸孔には、第１分断ドア止め載置体の第１載置底面に開口する分離用嵌入スリットを穿設することで、これにより第１軸ピン部を分離用軸孔に嵌合自在となし、組立作業の効率化を可能にしている。
【００１１】

【００１４】
本発明の請求項６に係るドアストッパーは上記の目的を達成するために下記の課題解決手段を特徴とする。すなわち請求項６に記載されたドアストッパーは、第１分断ドア止め載置体と第２分断ドア止め載置体と連枢保持機構とからなるとともに連枢保持機構が連枢軸ピンを具備するものであること、および、第１載置底面やドア装入側へ向けて低下する第１ドア止め傾斜上面やドア装入側に形成された第１衝当端面を第１分断ドア止め載置体が有するものであること、および、第１衝当端面と衝き当たる第２衝当端面や第１載置底面と面一状態で連続する第２載置底面や第１ドア止め傾斜上面と面一状態で連続してドア装入側へ向けて低下する第２ドア止め傾斜上面を第２分断ドア止め載置体が有するものであること、および、ドア装入側に位置する第２分断ドア止め載置体と反ドア装入側に位置する第１分断ドア止め載置体との相対関係において第１衝当端面と第２衝当端面とが互いに衝き当たるとともに第１載置底面・第２載置底面が面一状態で連続かつ第１ドア止め傾斜上面・第２ドア止め傾斜上面も面一状態で連続したときの床上載置状態や、当該床上載置状態の第２分断ドア止め載置体が反ドア装入側への上昇回動で第１ドア止め傾斜上面上に載置されたときの載置状態や、当該載置状態の第２分断ドア止め載置体がドア装入側への下降回動で上昇回動前の状態に復帰したときの床上載置状態を連枢保持機構が保持するものであること、および、連枢保持機構の連枢軸ピンが、第１分断ドア止め載置体を幅方向に貫通する第１軸孔内に装着された回動自在な第１軸ピン部と、第２分断ドア止め載置体に対して幅方向に装着された回動自在な第２軸ピン部と、第１軸ピン部の第１延出端部から第２軸ピン部の第２延出端部にわたる回動アーム部とからなるものであること、および、第１分断ドア止め載置体には、第１軸孔よりもドア装入側の位置にあって該第１軸孔と並列する分離用軸孔や、これら両孔間にあって第１軸孔と分離用軸孔とを連通するための狭小連通路が形成されていること、および、第１分断ドア止め載置体の第１衝当端面と第２分断ドア止め載置体の第２衝当端面とのうちで、一方の衝当端面には係嵌用突部が設けられているととともに他方の衝当端面には係嵌用突部と係合離脱自在に対応する係嵌用凹所が設けられていること、および、第１分断ドア止め載置体と第２分断ドア止め載置体との床上載置状態において、第１分断ドア止め載置体から第２分断ドア止め載置体を引き離すことで係嵌用突部と係嵌用凹所とを互いに離脱させたときには、連枢保持機構の第１軸孔に嵌合している第１軸ピン部が当該第１軸孔から狭小連通路を通じて分離用軸孔側に移動かつ嵌合するものであるとともに、当該分離用軸孔側に嵌合した第１軸ピン部を中心とする反ドア装入側への上昇回動で第２分断ドア止め載置体を第１分断ドア止め載置体の第１ドア止め傾斜上面上に載置保持したときには、第１軸ピン部が分離用軸孔から狭小連通路を通じて第１軸孔側に移動かつ嵌合するものであることを特徴とする。さらに本発明の請求項７に係るドアストッパーは、請求項６記載のものにおいて、第１分断ドア止め載置体には、第１軸ピン部を分離用軸孔に圧入するためのものとして、第１載置底面から分離用軸孔にわたり分離用嵌入スリットが開口されており、当該分離用嵌入スリットからの圧入によって第１軸ピン部が分離用軸孔と嵌合するものであることを特徴とする。
【００１５】
【発明の実施の形態】
本願の請求項１につき先ず図１および図２によって説示すると、その要旨は第１分断ドア止め載置体１と第２分断ドア止め載置体２とが直列状態にて連装配置させるようにし、当該第１、第２分断ドア止め載置体１、２を連枢保持機構３によって連枢させることにより、第２分断ドア止め載置体２を上記の低位置状態から、第１分断ドア止め載置体１の第１ドア止め傾斜上面１ａに回動自在となるよう載置可能な構成とするのである。
【００１６】
すなわち、上記第１分断ドア止め載置体１には、床面に載置される第１載置底面１ｂと、ドア装入側Ｓ１へ向けて低下している第１ドア止め傾斜上面１ａと、ドア装入側Ｓ１に形成された第１衝当面１ｃ、そして第２分断ドア止め載置体２の幅員方向と直交状に形成された一対の側面１ｄとが形成されている。
これに対し第２分断ドア止め載置体２にあっては、前記の第１ドア止め傾斜上面１ａと面一状態にて、ドア装入側Ｓ１へ向けて低下するよう低位置状態にあって連装されている第２ドア止め傾斜上面２ａと、この際前記第１載置底面１ｂと面一状態にて床面に載置されるよう連装される第２載置床面２ｂとを具有しているだけでなく、さらに前記した第１衝当端面１ｃに対向する第２衝当端面２ｃをも備えている。ここで図示例では第２分断ドア止め載置体２における一対の第２側面２ｄが、第１側面１ｄと夫々面一状態で連装されている。
【００１７】
さらに、ここで用いられる連枢保持機構３の構成につき以下説示すると、上記した第１分断ドア止め載置体１と直列状態にて隣装されている第２分断ドア止め載置体２を反ドア装入側Ｓ２へ向けて上昇回動することにより、その第２載置底面２ｂを第１ドア止め傾斜上面１ａである高位置に昇動変移した載置状態とすることができ、かつ当該昇降変移前の低位置である床上載置状態に返戻することも自在であり、しかもこれらの低位置状態と高位置状態を夫々保持することができるようにしてある。
【００１８】
ここで、上記の連枢保持機構３につき、図１と図２を参照することで請求項２のドアストッパーに係る一実施態様によって以下詳記すると、当該連枢保持機構３なるものは、第１分断ドア止め載置体１の幅員方行すなわち第１側面１ｄと直交状に、回動自在なるよう軸装した第１軸ピン部３ａと、第２分断ドア止め載置体２の幅員方行すなわち第２側面２ｄと直交状にて、回動自在なるよう軸装した第２軸ピン部３ｂと、第１、第２軸ピン部３ａ、３ｂの第１、第２側面１ｄ、２ｄから突出している第１、第２延出端部３ｃ、３ｄの一方または両方を連設した回動アーム部３ｅとからなる連枢軸ピン３Ａを具有している。
【００１９】
従って請求項２における連枢保持機構３としては、図１２に示されているようなＣ字状の連枢軸ピン３Ａとしなくとも、第１、第２軸ピン部３ａ、３ｂの片側だけの第１、第２延出端部３ｃ、３ｄを回動アーム部３ｅによって連設し、かつ第２軸ピン部３ｂも第１分断ドア止め載置体１の全幅長にわたって形成することにより、コ字状に形成するようにしてもよい。
ここで図中第１、第２軸孔１ｅ、２ｅには、上記の第１、第２軸ピン部３ａ、３ｂが回動自在に嵌装されている。
【００２０】
次に請求項３にあっては、請求項２における連枢保持機構３に関し以下の如くさらに特定されている。
すなわち、その連枢軸ピン３Ａが、第１軸ピン部３ａの両端における一対の第１延出端部３ｃと、第２軸ピン部３ｂのこれまた両端における一対の第２延出端部３ｄとを、第１、第２分断ドア止め載置体１、２の第１、第２側面１ｄ、２ｄに沿装された一対の回動アーム部３ｅによって一体に形成されている。
しかも、それだけでなく第１分断ドア止め載置体１の第１載置底面１ｂに開口された図２に示す嵌入用スリット１ｆから上記の第１軸ピン部３ａを圧入することで、当該嵌入用スリット１ｆと連通する第１軸孔１ｅに回動自在なるよう嵌合されるのであり、このようなことは第１、第２分断ドア止め載置体１、２が本来ゴム軟質合成樹脂材により形成されている場合に好都合である。
さらに、前記した第２軸ピン部３ｂは、一対の回動アーム部３ｅから夫々曲折した一対の対向軸杆３ｆを、第２分断ドア止め載置体２における前記第２軸孔２ｅに嵌入することで構成されるようにしてある。
【００２１】
このようにすることで、図１に示すように金属または合成樹脂により形成されたＣ字状である連枢保持機構３につき、例えば先ず前記した対向軸杆３ｆを、その弾性に抗して離間することで開成し、これにより第２軸孔２ｅに係嵌してしまい、次いで第１軸ピン３ａを第１分断ドア止め載置体１の嵌入用スリット１ｆから第１軸孔１ｅへと嵌合するといった容易な操作で、連枢軸ピン３Ａを第１、第２分断ドア止め載置体１、２間に装填することができ、かつ第１軸ピン部３ａは、嵌入用スリット１ｆの切設により、第１軸孔１ｅ内における円滑なる回動が保証されることにもなる。
【００２２】
そして請求項４にあっては、図示例のように第１、第２分断ドア止め載置体１、２における第１、第２衝当端面１ｃ、２ｃが、第１、第２ドア止め傾斜上面１ａ、２ａから、夫々第１、第２載置底面１ｂ、２ｂに向けてドア装入側Ｓ１へ近づくよう傾斜させて形成するようにしてある。従って図１（Ｂ）に明示の如く第１分断ドア止め載置体１に対して、第２分断ドア止め載置体２が、第１軸ピン部３ａを中心とし、回動アーム部３ｅを半径として仮想線Ｒ１のように回動し、第１分断ドア止め載置体１を第２分断ドア止め載置体２上に回動載置しようとする際、不本意に干渉されることなく円滑なる当該回動が保証され、仮想線Ｒ２の状態から矢印Ｒ３のように、第１分断ドア止め載置体１を回動することで、これを仮想線Ｒ４のように第１分断ドア止め載置体１を上である高位置に載置させ易いことになる。
【００２３】
次に請求項５について図３により説示すると、ここでは前記した請求項２に係るドアストッパーにおいて、前掲第１、第２衝当端面１ｃ、２ｃが図１、図２に例示したものと相違し、以下の如き構成を有している。
すなわち、第１、第２分断ドア止め載置体１、２における第１、第２衝当端面１ｃ、２ｃが、第１、第２ドア止め傾斜上面１ａ、２ａから夫々第１、第２載置底面１ｂ、２ｂに向けて、ドア装入側Ｓ１寄りまで曲成されているだけでなく、第１衝当端面１ｃには、第１上位傾斜面１ｇと第１下位傾斜面１ｈとの間にあって、図示例では円弧状の係合凹所１ｉが連設されている。
これに対して第２衝当端面２ｃには、上記した第１上位傾斜面１ｇと当接する第２上位傾斜面２ｇと、第１下位傾斜面１ｈと当接することになる第２下位傾斜面２ｈと、上記した係合凹所１ｉに嵌合載置されることになる係合凸所２ｉが連設されているのである。
【００２４】
従って当該請求項５によるときは、前説の請求項４による場合と同様にして第２分断ドア止め載置体２は、矢印Ｒ１、仮想線Ｒ２、Ｒ３、Ｒ４により説示した通り第１分断ドア止め載置体１上に開動載置できるだけでなく、第２分断ドア止め載置体２の低位置における床上載置状態にあっては、係合凹所１ｉに係合凸所２ｉが係合載置されていることから、外力によって不本意に第１分断ドア止め載置体１から第２分断ドア止め載置体２が離脱してしまうことなく、ドアストッパーとしての安定した使用が可能となる。
【００２５】
次に請求項６に係るドアストッパーについて図４ないし図７により以下詳記するが、その基本的構成は請求項２について記述した内容と同じであり、従って以下請求項１との相違点について明示する。
すなわち、ここでの連枢保持機構３にあっても、第１分断ドア止め載置体１の幅員方向へ貫設した第１軸孔１ｅに回動自在なるよう軸装した第１軸ピン部３ａと、第２分断ドア止め載置体２の幅員方向へ回動自在なるよう軸装第２軸ピン部３ｂと、第１、第２軸ピン部３ａ、３ｂの第１、第２延出端部３ｃ、３ｄを連設した回動アーム部３ｅとからなる連枢軸ピン３Ａを具有している点については、同一構成である。
しかし請求項６にあっては、第１分断ドア止め載置体１の上記した第１軸孔１ｅだけではなく、これには狭小連通路１ｊを介してドア装入側Ｓ１にあって並設の分離用軸孔１ｋが連設されているのである。
【００２６】
さらに前記の第１、第２分断ドア止め載置体１、２に形成されている第１、第２衝当端面１ｃ、２ｃの構成が相違しており、その任意に選択した一方である第１衝当端面１ｃには係嵌用突部１ｍを形成し、他方である第２衝当端面２ｃには上記の係嵌用突部１ｍが係合する係嵌用凹所２ｊを夫々設けるようにする。
ここで図示例では係嵌用突部１ｍと係嵌用凹所２ｊの何れもが、第１、第２衝当端面１ｃ、２ｃの中央部から角状に突設されており、従って第１、第２衝当端面１ｃ、２ｃのにおける第１、第２外周平面１ｎ、２ｋが当接自在となる場合が例示されており、もちろん、第１衝当端面１ｃに係嵌用凹所を、そして第２衝当端面２ｃに係嵌用突部を形成するようにしてもよく、また当該第１、第２外周平面１ｎ、２ｋとして例示のものは、第１、第２ドア止め傾斜上面１ａ、２ａに対して直交状となるよう形成され、第１分断ドア止め載置体１から第２分断ドア止め載置体２を引出し易くしている。
【００２７】
従って図６、図７によって理解されるように、前記した第１、第２分断ドア止め載置体１、２が既設の床上載置状態にあって、第１分断ドア止め載置体１から第２分断ドア止め載置体２を引き離すようにすることで、係嵌用突部１ｍから係嵌用凹所２ｊを離脱するようにすれば、連枢保持機構３における第１軸孔１ｅに嵌合していた第１軸ピン部３ａが、前記した狭小連通路１ｊを介して分離用軸孔１ｋへ転移嵌合することになる。
この結果第２分断ドア止め載置体２が、上記の分離用軸孔１ｋを中心として、第１分断ドア止め載置体１の第１ドア止め傾斜上面１ａ上に昇動変移させ得ることになると共に、さらに第１軸ピン部３ａを当該分離用軸孔１ｋから、再び第１軸孔１ｅへ前記の狭小連通路１ｊを介して転移させることができ、かくして第１分断ドア止め載置体１を高位置に昇動変移した載置状態にあって安定化させることが可能となる。
【００２８】
そして請求項７にあっては、上記請求項６において、前記請求項３と同様にして、第１載置底面１ｂに開口の分離用嵌入スリット１ｔから圧入することで、第１軸ピン部３ａが嵌合自在とするようにして前記の目的を達成し得るようにしている。

In addition to being formed in a C-shape by the rod, the first shaft pin portion can be fitted into the first shaft hole from the fitting slit of the first divided door stopper mounting body, Further, it is an object of the present invention to allow the pair of opposed shaft rods to be fitted into the second shaft hole of the second divided door stopper mounting body from the outside so that the assembling operation can be performed quickly and easily.
[0008]
According to a fourth aspect, in the second aspect, the first and second abutting end surfaces of the first and second divided door stopper mounting bodies approach the door loading side downward. In this manner, the second divided door stopper mounting body can be smoothly moved up and down relative to the first divided door stopper mounting body, and the second divided door stopper mounting body can be smoothly moved. It is an object of the present invention to enable a smooth reversible up-and-down movement of a body from a low position to a high position.
[0009]
In the case of a fifth aspect, in the configuration of the fourth aspect, the first and second abutting end faces are both formed by flat inclined planes, but each of the first and second abutment end faces is formed by a mutually engaging engagement face. The first and second divided door stopper mounting bodies are both at a low position and are continuously mounted in a state of being mounted on the floor by making the recesses into engagement with the engagement projections. In this case, the stability of the connected state is ensured, and the integrated state of the first and second divided door stopper mounting bodies is ensured without being unintentionally separated. .
[0010]
Next, the basic structure of the sixth aspect is the same as that of the first aspect, but the first and second abutment end faces and the respective components of the pivot holding mechanism are different as follows.
That is, first, the first and second abutting end surfaces are configured to be fitted with the engagement projection and the engagement recess, and the pivot shaft pin in the pivot holding mechanism can be held in a predetermined pivot state. By doing so, it is possible to stably secure the connection state of the first and second divided door stopper mounting bodies, and to provide the first divided door stopper mounting body with a first shaft pin portion of the connecting pivot pin. In addition to the first shaft hole in which is fitted, the separation shaft hole is provided in parallel with the first shaft hole via a narrow communication passage. Then, the first shaft pin portion is disengaged and transferred from the first shaft hole to the separation shaft hole, so that the first divided door stopper mounting member and the second divided door stopper mounting member are separated from each other, and the first divided door stopper mounting member is separated. The door stop mounting body can be mounted on the second divided door stop mounting body by moving up and down, and the mounting state is such that the first shaft pin portion is moved from the separating shaft hole to the first shaft hole. By returning to, a stable state can be secured.
According to a seventh aspect of the present invention, in the sixth aspect of the present invention, the separation shaft hole is provided with a separation fitting slit that is opened on the first mounting bottom surface of the first divided door stopper mounting body. As a result, the first shaft pin can be freely fitted into the separation shaft hole, and the efficiency of the assembling work can be increased.

BEST MODE FOR CARRYING OUT THE INVENTION
First, claim 1 of the present application will be described with reference to FIGS. 1 and 2. The gist of the present invention is that the first divided door stopper mounting body 1 and the second divided door stopper mounting body 2 are arranged in series in a serial state, The first and second divided door stoppers 1 and 2 are pivoted by the pivotal holding mechanism 3 to move the second divided door stopper and holder 2 from the low position to the first divided door stopper. The configuration is such that the mounting body 1 can be mounted on the first door stopper inclined upper surface 1a so as to be rotatable.
[0016]
That is, the first split door stop mounting body 1 has a first mounting bottom surface 1b mounted on the floor surface and a first door stop inclined upper surface 1a which is lowered toward the door loading side S1. , A first abutment surface 1c formed on the door loading side S1, and a pair of side surfaces 1d formed orthogonal to the width direction of the second divided door stopper mounting body 2.
On the other hand, the second divided door stopper mounting body 2 is in the low position state so as to be lowered toward the door loading side S1 in a state flush with the first door stopper inclined upper surface 1a. It has a second door stop inclined upper surface 2a which is continuously mounted, and a second mounting floor surface 2b which is continuously mounted so as to be mounted on the floor in a state flush with the first mounting bottom surface 1b. In addition to the above, there is further provided a second abutment end face 2c facing the first abutment end face 1c. Here, in the illustrated example, a pair of second side surfaces 2d of the second divided door stopper mounting body 2 are connected to the first side surface 1d in a state of being flush with each other.
[0017]
Further, the configuration of the pivot holding mechanism 3 used here will be described below. The second divided door stopper mounting body 2 which is mounted next to the first divided door stopper mounting body 1 in series with the above-described first divided door stopper mounting body 1 is inverted. By rotating upward toward the door loading side S2, the second placement bottom surface 2b can be placed in a placement state in which the second placement bottom surface 2b is raised and displaced to a high position which is the first door stopper inclined top surface 1a. It is also possible to return to the on-floor mounting state, which is the low position before the vertical movement, and it is possible to maintain these low position state and high position state respectively.
[0018]
Here, the pivot holding mechanism 3 will be described in detail below with reference to FIGS. 1 and 2 according to an embodiment of the door stopper according to claim 2. The width of the 1-divided door stopper mounting body 1, that is, the first shaft pin portion 3 a that is rotatably mounted in a direction orthogonal to the first side surface 1 d, and the width of the second divided door stopper mounting body 2. The second shaft pin portion 3b, which is rotatably mounted in a row, that is, orthogonal to the second side surface 2d, and the first and second side surfaces 1d, 2d of the first and second shaft pin portions 3a, 3b. There is provided a pivot pin 3A comprising a rotating arm 3e provided with one or both of the protruding first and second extended ends 3c and 3d.
[0019]
Therefore, as the pivot holding mechanism 3 in claim 2, the C-shape pivot pin 3A as shown in FIG. 12 is not used, but the first and second pivot pins 3a, 3b are provided on one side only. The first and second extended ends 3c and 3d are continuously provided by a rotating arm 3e, and the second shaft pin 3b is also formed over the entire width of the first divided door stopper mounting body 1, thereby forming a U-shape. It may be formed in a shape.
Here, the first and second shaft pin portions 3a and 3b are rotatably fitted in the first and second shaft holes 1e and 2e in the drawing.
[0020]
Next, in the third aspect, the pivot supporting mechanism 3 in the second aspect is further specified as follows.
In other words, the pivot pin 3A is connected to a pair of first extending ends 3c at both ends of the first shaft pin 3a, and a pair of second extending ends 3d at both ends of the second shaft pin 3b. Is integrally formed by a pair of rotating arm portions 3e provided along the first and second side surfaces 1d and 2d of the first and second divided door stopper mounting bodies 1 and 2.
In addition, the first shaft pin portion 3a is press-fitted from the fitting slit 1f shown in FIG. 2 which is opened in the first placement bottom surface 1b of the first split door stop placement body 1 to thereby perform the fitting. Is rotatably fitted in the first shaft hole 1e communicating with the first slit 1f. This is because the first and second divided door stopper mounting bodies 1 and 2 are originally made of rubber soft synthetic resin material. It is advantageous when it is formed by
Further, the second shaft pin portion 3b fits the pair of opposed shaft rods 3f bent from the pair of rotating arm portions 3e into the second shaft holes 2e of the second divided door stopper mounting body 2. It is made up of things.

Then, the first shaft pin 3a is engaged with the second shaft hole 2e, and then the first shaft pin 3a is fitted into the first shaft hole 1e from the fitting slit 1f of the first divided door stopper mounting body 1. By an easy operation such as joining, the connecting pivot pin 3A can be loaded between the first and second divided door stopper mounting bodies 1 and 2, and the first pivot pin portion 3a is cut into the fitting slit 1f. This also ensures smooth rotation in the first shaft hole 1e.
[0022]
According to the fourth aspect, the first and second abutting end faces 1c and 2c of the first and second divided door stopper mounting bodies 1 and 2 are inclined to the first and second door stoppers as in the illustrated example. The upper surfaces 1a and 2a are formed so as to be inclined toward the first and second mounting bottom surfaces 1b and 2b so as to approach the door loading side S1. Therefore, as clearly shown in FIG. 1 (B), the second divided door stopper mounting body 2 is connected to the first divided door stopper mounting body 1 around the first shaft pin 3a and the rotating arm part 3e. When rotating as the imaginary line R1 as a radius, and trying to place the first divided door stopper mounting body 1 on the second divided door stopper mounting body 2 without being unintentionally interfered. By smoothly rotating the first divided door stopper mounting body 1 as indicated by an arrow R3 from the state of the virtual line R2, the first divided door stopper is moved as indicated by an imaginary line R4. This makes it easier to mount the mounting body 1 at a high position, which is above.
[0023]
Next, claim 5 will be described with reference to FIG. 3. Here, in the door stopper according to claim 2, the first and second abutment end faces 1 c and 2 c are different from those illustrated in FIGS. 1 and 2. Has the following configuration.
That is, the first and second abutment end surfaces 1c and 2c of the first and second divided door stopper mounting bodies 1 and 2 are respectively separated from the first and second door stopper inclined upper surfaces 1a and 2a by the first and second mounting surfaces. In addition to being bent toward the door loading side S1 toward the bottom surfaces 1b and 2b, the first abutting end surface 1c has a space between the first upper inclined surface 1g and the first lower inclined surface 1h. In the illustrated example, an arc-shaped engaging recess 1i is continuously provided.
On the other hand, on the second abutting end face 2c, the second upper inclined face 2g which comes into contact with the first upper inclined face 1g and the second lower inclined face 2h which comes into contact with the first lower inclined face 1h. And the engagement convex portion 2i to be fitted and mounted in the above-described engagement concave portion 1i.
[0024]
Therefore, in the case of the fifth aspect, similarly to the case of the fourth aspect, the second divided door stopper mounting body 2 moves the first divided door stopper as indicated by the arrow R1, the virtual lines R2, R3, and R4. In addition to being able to be opened and placed on the mounting body 1, when the second split door stopper mounting body 2 is placed on the floor at a low position, the engaging convex portion 2 i is engaged with the engaging concave portion 1 i. Since it is placed, the second divided door stop mounting body 2 does not unintentionally detach from the first divided door stop mounting body 1 due to an external force, and can be used stably as a door stopper. .
[0025]
Next, the door stopper according to the sixth aspect will be described in detail with reference to FIGS. 4 to 7. The basic configuration is the same as that described in the second aspect, and therefore, the differences from the first aspect will be explicitly described below. I do.

An engaging projection may be formed on the second abutting end face 2c, and the first and second outer peripheral planes 1n and 2k are exemplified by the first and second door stopper inclined upper surfaces 1a. , 2a so as to be orthogonal to the first split door stop mounting body 1 so that the second split door stop mounting body 2 can be easily pulled out.
[0027]
Therefore, as can be understood from FIGS. 6 and 7, the first and second divided door stoppers 1 and 2 are placed on the existing floor, and the first and second divided door stoppers 1 and 2 are separated from each other. By detaching the second split door stopper mounting body 2 and thereby detaching the engagement recess 2j from the engagement projection 1m, the first shaft hole 1e in the pivot support mechanism 3 can be removed. The fitted first shaft pin portion 3a is transferred and fitted to the separation shaft hole 1k via the narrow communication passage 1j.
As a result, the second divided door stopper mounting body 2 can be moved up and down on the first door stopper inclined upper surface 1a of the first divided door stopper mounting body 1 around the separation shaft hole 1k. At the same time, the first shaft pin portion 3a can be transferred from the separation shaft hole 1k to the first shaft hole 1e again via the narrow communication passage 1j, and thus the first divided door stopper mounting body is provided. 1 can be stabilized in the mounted state where it has been raised and shifted to a high position.
[0028]
According to the seventh aspect, in the sixth aspect, similarly to the third aspect, the first shaft pin portion 3a is press-fitted into the first mounting bottom surface 1b from the separation fitting slit 1t of the opening. Can be fitted so that the above object can be achieved.

The first and second split door stopper mounting bodies 1 and 2 are provided with several first and second cutout vacancies 1q and 2n that open to the first and second mounting bottom surfaces 1b and 2b. The plurality of first and second partition leg plates 1r and 2p are arranged side by side in the width direction, so that appropriate elasticity is achieved, and the overall weight is also reduced.
Further, the second partition leg plate 2p is formed to have a size that slightly floats from the second placement bottom surface 2b, so that the second partition leg plate 2p can have more elasticity and easily exert its effect as a door stopper.
Further, on the first door stopper inclined upper surface 1a, a steeply inclined portion 1S toward the door loading side S1 is formed on a lower side thereof, so that the first divided door stopper mounting body 1 is formed. The second turning door stopper mounting body 2 can be easily rotated upward without any trouble.
[0030]
Further, in the illustrated example, as clearly shown in FIGS. 5 and 6, the first and second divided door stopper mounting bodies 1 and 2 are formed on the first and second side surfaces 1d and 2d to have a narrower width. 6, the first and second ridges 1u and 2q for the rotating arm portion are provided so as to protrude, and as understood from FIG. 6, the rotating arm portion 3e of the pivot pin 3A is The first and second pivoting arm ridges 1u and 2q are locked by getting over them, so that the first and second divided door stopper mounting bodies 1 and 2 are placed on the floor or raised. In the transition state, unintended rotation displacement is prevented, so that reliability for stability can be enhanced.
[0031]
【The invention's effect】

Since the two are arranged in series, they can be reduced in size without being bulky. In addition, when the first divided door stopper mounting body is moved up and down to a high position, its length is almost 1/2. Not only does not obstruct pedestrians, it is convenient for storage, but also secures a sufficient height position, further simplifies the structure of the pivot holding mechanism itself, and reduces the assembly work. Simplification can also be achieved.
[0032]
According to a second aspect of the present invention, as compared with the first aspect, the present invention relates to a pivot holding mechanism, wherein the pivot pin comprises a first and a second pivot pin and a pivot arm which connects the first and the second extended ends. Since the first and second divided door stopper mounting members are connected to each other, the purpose of holding the low position state and the high position state can be achieved by using an extremely simple member. .
According to a third aspect of the present invention, in the second pivot holding mechanism, the pivot pin is formed in a C-shape, and the first split door stopper mounting body is provided with a slit for insertion into the first shaft hole. As a result, the work of attaching the connecting pivot pin to the first and second divided door stopper mounts can be performed easily and quickly.
Further, in the case of claim 4, the first and second abutting end faces of the first and second divided door stopper mounting bodies are inclined in a predetermined direction in the above-described claim 2, so that the first divided door stopper mounting body is inclined. The work of ascending and descending movement for the table can be performed more smoothly and easily.
[0033]
Next, according to a sixth aspect, the first and second abutting end surfaces of the first and second divided door stopper mounting bodies are selectively provided with engagement projections and engagement recesses. This allows the first and second divided door stopper mounting bodies to be firmly connected to each other, so that a stable door stopper that does not unintentionally come off can be provided.
Moreover, even in the pivot holding mechanism, the first pivot pin portion of the pivot pin is configured to be detachable from the pivot shaft hole to the separating shaft hole via the narrow communication passage, so that the first pivot pin portion can be moved. The detachment operation of the first and second divided door stopper mounting bodies can be easily performed irrespective of whether the engaging projection is engaged with the engaging recess, and the first shaft pin portion is separated. It is also possible to returnly engage with the connecting shaft hole from the shaft hole via the narrow connecting path, and as a result, the first and second divided door stopper mounting bodies can be securely loaded in a high position at a high position. Stable state can be secured.
According to a seventh aspect of the present invention, assembling work is facilitated by adopting the one having the separating shaft hole in the separating shaft hole in the sixth aspect.
