Description

【０００１】
【発明の属する技術分野】
本発明は、扉の開動作の範囲を制限する戸当りに関する。
【０００２】
【背景技術】
扉の開き過ぎにより、扉に付属するハンドルやドアノブ等の突出物が壁や窓等に当たって、これらが損傷を受けたり、扉を支持する蝶番が変形や破損してしまうことを防止するために、扉の開動作の範囲を制限するための戸当りが知られている。
従来、このような戸当りは、床や壁に固定され、開けた扉に当接することで、この当接する位置を超えて扉が開かないようにするものである。通常、戸当りの扉に当接する部分には、当接時の衝撃を緩和するためにゴムや合成樹脂製の緩衝材が設けられている。また、戸当りおよび戸当りと当接する扉の互いに対向する位置には、フックおよびリングが設けられており、これらのフックおよびリングの係合によって、扉を開放状態位置に維持できるようになっている。
【０００３】
しかし、上述の床や壁に固定される戸当りは、床や壁から突出して設けられているため、掃除の際に邪魔になるという不都合がある。特に、掃除機を用いて掃除する場合には、通常使用される幅広のノズルでは戸当りにぶつかってしまい、その周辺がきれいにできないため、隙間用の細いノズルに付け換える必要があり掃除に手間が掛かってしまう。
このような不都合の解消を目的に考案された戸当りとして、実開平６−１６７７号公報に開示された戸当り（従来例１）、および特開平１０−３３９０６７号公報に開示された戸当り（従来例２）が提案されている。
【０００４】
従来例１の戸当りは、床面下に収納可能に構成されたものであって、床内に埋め込まれた筒体と、この筒体内に収納および床面から突出可能に取り付けられた戸当り部と、この戸当り部を上方に付勢するコイルスプリングとを備えている。さらに、この戸当りは、筒体内に戸当り部を収納した収納状態を維持し、また、収納状態を解除するための機構を備えている。
従って、従来例１の戸当りでは、戸当り部を筒体内に収納することにより、床面から突出する部分がなくなるので、床面を掃除しやすくできるとともに、戸当り部の収納状態を解除して床面から突出させることで、戸当りとして機能させることができる。
【０００５】
従来例２の戸当りは、戸当り部材と固定部材とを備えたものであって、固定部材が床面および壁面に固定され、この固定部材に対して戸当り部材が着脱自在に取り付けできるように構成されたものである。すなわち、固定部材は、板材を折り曲げてＬ字形に形成され、床面および壁面の交差部にビス止め固定され、戸当り部材は、凹部を有して形成されており、戸当り部材の凹部を固定部材に嵌合することで、戸当り部材が着脱自在に取り付けられる。そして、扉が戸当り部材に当接する際の荷重が固定部材の壁面に沿った立ち上がり部分および壁によって支持される構造となっている。
従って、従来例２の戸当りでは、戸当り部材を着脱自在に固定部材に取り付けできることにより、掃除の際には戸当り部材を固定部材から外すことで、戸当りが邪魔にならず掃除しやすくできる。
【０００６】
【発明が解決しようとする課題】
しかしながら、従来例１の戸当りでは、筒体やコイルスプリング、収納および解除機構等の部品点数が多く、構造が複雑になってしまい製造コストが高くなるという問題がある。さらに、筒体を床内に埋め込む必要があるため、床に孔や凹みを形成しなければならず、戸当りの取付施工に手間が掛かり、取り付け後の交換も困難であるという問題がある。
また、従来例２の戸当りでは、Ｌ字形の固定部材を床面および壁面の交差部に固定することで扉が当接する荷重を支持しているため、壁面から離して設置する場合には、固定部材の立ち上がり部分のみで荷重を支持できるだけの部材寸法が必要になる。すなわち、戸当り部材が転倒しないためには、固定部材の立ち上がり部分が戸当り部材と同程度の高さ寸法を備える必要があるので、戸当り部材を外しても固定部材の立ち上がり部分が床面から突出してしまうことになる。従って、従来例２の戸当りを壁面から離して設置すると、掃除の際に邪魔にならないという上述の効果を得ることができず、取付位置が限定されてしまうという問題がある。
【０００７】
本発明の目的は、必要に応じて容易に取り外し可能、かつ、構造が単純にでき、施工および交換が容易で、取付位置の自由度が高い戸当りを提供することにある。
【０００８】
【課題を解決するための手段】
本発明の戸当りは、床または壁に固定される固定部材と、この固定部材に着脱自在に取り付けられる戸当り本体とを備え、前記固定部材および前記戸当り本体のいずれか一方には、他方に設けられた係合凹部に係合する係合凸部が設けられ、前記係合凸部は、前記係合凹部に向かって突出する突出部と、この突出部の先端側に設けられ当該突出部の突出方向と交差する方向に延出する突片とを有し、前記係合凸部および前記係合凹部を互いに所定方向にずらして、前記突片が当該係合凹部を係止することで、前記固定部材が固定された床または壁から離れる方向への前記戸当り本体の移動が規制されることを特徴とする。
【０００９】
なお、ここで、係合凸部および係合凹部を互いにずらす「所定方向」とは、戸当り本体に扉が当接した際に作用する力や、戸当り本体の自重等の作用荷重によって、戸当り本体が容易に固定部材から外れてしまうことのない方向を意味する。すなわち、係合凸部および係合凹部を互いにずらして係合させる方向と逆向きの荷重が作用しないように、適宜ずらす方向を設定できる。また、「所定方向」は、直線に沿った一方向や、途中に折れ曲がり部分を含んだ二方向以上の方向、円弧等の曲線に沿った回転方向でもよい。
【００１０】
このような本発明によれば、戸当りを固定部材および戸当り本体から構成し、床または壁に固定した固定部材に戸当り本体を着脱自在に取り付け可能としたことにより、掃除の際に必要に応じて容易に取り外すことができる。
また、固定部材および戸当り本体に、互いに係合する係合凸部および係合凹部を設けるだけの単純な構造としたことにより、床に孔や凹みを設ける必要がなく、取付施工や交換の作業が容易にできる。
さらに、係合凸部の突片が係合凹部を係止することにより、係合凸部や係合凹部の寸法を大きくしなくても係合状態を維持でき、固定部材の寸法を小さくできるので邪魔にならず、固定部材を床または壁の任意の位置に取り付けられ、取付位置の自由度が高くできる。また、戸当り本体が固定部材から不用意に外れることがないので、戸当りとしての機能が損なわれることなく、扉の開き過ぎを防止できる。
【００１１】
また、本発明の戸当りでは、前記突出部の先端には、前記突片を当該突出部の全周に渡って設けた頭部が形成され、前記係合凹部は、前記突出部が挿通可能で、かつ前記頭部が挿通不能な孔径を有した小孔部と、前記頭部が挿通可能な孔径を有した大孔部とが連続して形成された係合孔であり、前記大孔部に挿通された前記突出部および前記頭部を前記小孔部の方向にずらすことで、当該頭部が当該小孔部の縁を係止することを特徴とする。
このような構成では、突出部の先端全周に渡って設けた突片で形成された頭部を有する係合凸部と、大孔部および小孔部が連続形成された係合孔とが係合することにより、係合凸部として例えば、頭付きのピン等を採用することで、より簡単に係合凸部を形成できるとともに、係合孔の小孔部の縁を頭部が係止することで、小孔部から大孔部へ向かう以外の方向への移動が規制され、戸当り本体をより確実に取り付けることができる。すなわち、扉が当接する時の力や自重等の外力が作用する方向に対して、係合孔の大孔部および小孔部を適切に配置することで、戸当り本体が固定部材から不用意に外れないようにできる。
【００１２】
また、本発明の戸当りでは、前記係合凸部が設けられる前記固定部材または前記戸当り本体は、少なくとも一部が板状部材から構成されており、前記係合凸部の突出部および突片は、前記板状部材の一部を切り起こして曲げ加工により形成され、前記係合凹部は、前記突出部および突片が挿通可能な孔径を有した係合孔であり、前記突出部および突片を前記係合孔に挿通し、当該突片の延出方向にずらすことで、当該突片の先端側が前記係合孔の縁を係止することを特徴とする構成が採用できる。
このような構成では、固定部材または戸当り本体を構成する板状部材の一部を切り起こして曲げ加工により係合凸部を形成することで、係合凸部を構成するために別部材を用意する必要がなく、部品点数の削減を図ることができる。また、係合孔の縁を突片の先端側が係止することで、戸当り本体の移動が規制され、取り付け状態を確実に維持できる。
【００１３】
さらに、本発明の戸当りでは、前記戸当り本体と前記固定部材とを圧着させる弾性部を備えたことを特徴とする。
なお、ここで弾性部とは、戸当り本体や固定部材に取り付けられる別部材としての弾性部材であってもよく、また、戸当り本体や固定部材の一部を加工して形成したものでもよい。
このような構成では、戸当り本体と固定部材とを圧着させる弾性部を備えることにより、戸当り本体を固定部材に密着して取り付けることができ、戸当り本体と固定部材とのがたつきやずれを防止して、両者の取付状態を良好に維持できる。
【００１４】
また、本発明の戸当りでは、前記係合凸部が前記固定部材に設けられ、前記係合凹部が前記戸当り本体に設けられたことを特徴とする。
このような構成では、床または壁に固定される固定部材に係合凸部を設け、戸当り本体に係合凹部を設けることにより、係合凸部が設けられた部分以外の固定部材の厚さ寸法を小さくでき、戸当り本体を外した状態において、固定部材の床や壁からの出張りを小さくし、より邪魔にならないようにできる。また、ごみやほこりが溜まりやすい床側や壁側に係合孔を設けないので、係合孔にごみやほこりが溜まって戸当り本体の着脱が困難になる不具合を回避できる。
【００１５】
【発明の実施の形態】
以下、本発明の各実施形態を図面に基づいて説明する。なお、第２実施形態以降において、次の第１実施形態で説明する構成部材と同じ構成部材、および同様な機能を有する構成部材には、第１実施形態の構成部材と同じ符号を付し、それらの説明を省略または簡略化する。
【００１６】
〔第１実施形態〕
図１ないし図３に、第１実施形態に係る戸当り１０を示す。図１は、戸当り１０の構成を示す分解斜視図であり、図２は、戸当り１０の取付方法を示す斜視図であり、図３は、戸当り１０の取付状態を示す縦断面図である。
図１ないし図３において、戸当り１０は、建物等の床１に固定された固定部材１１と、この固定部材１１に着脱自在に取り付けられる戸当り本体２０と、固定部材１１に取り付けられた弾性部としての波形座金１５とを備えて構成されている。
戸当り１０は、図示しない扉の開き過ぎにより、扉に付属するハンドルやドアノブ等の突出物が壁２に当たって、この壁２が損傷を受けることを防止するために、扉の開動作の範囲を制限するものであって、この戸当り１０に図１中下方右側から扉が当接することで、その当接した位置を超えて扉が壁２の側へ行き過ぎないようになっている。
【００１７】
固定部材１１は、角が丸められた略三角形状の金属製板材からなり、１つの角を壁２に向け、この角と対向する辺を壁２に略平行にして、３つの角の近辺にそれぞれ設けられたビス孔１９を挿通するビス１８によって床１の表面に固定されている。固定部材１１の上面には、係合凸部としての２つの係合ピン１２が壁２と交差する方向に並べて突設されている。なお、係合ピン１２を壁２と平行になるように並べて突設してもよい。
係合ピン１２は、固定部材１１の上面から上方に突出する突出部としての幹部１２Ａと、この幹部１２Ａの上端に一体的に形成され、幹部１２Ａよりも水平投影面積の大きい頭部１２Ｂとを有している。すなわち、係合ピン１２は、略円柱状の幹部１２Ａと、この幹部１２Ａよりも径の大きな略円板状の頭部１２Ｂとから縦方向の断面略Ｔ字形に形成されている。
なお、係合ピン１２の高さ寸法は、本実施形態において固定部材１１の上面から１０ｍｍ以下に設定されている。
【００１８】
弾性部としての波形座金１５は、リング状の座金の円周に沿って波形に形成されたもので、２つの係合ピン１２それぞれの幹部１２Ａが挿通されて固定部材１１に取り付けられている。また、波形座金１５は、その内径が係合ピン１２の頭部１２Ｂよりも小さくなっており、頭部１２Ｂに引っ掛かるため、係合ピン１２から外れないようになっている。
なお、弾性部としては、波形座金１５に限らず、皿ばねやコイル状のばね座金等の弾性部材が採用できる。また、このような別体の弾性部材を取り付けるものに限らず、固定部材１１の一部を切り起こす等の方法により弾性部を形成してもよい。
【００１９】
戸当り本体２０は、固定部材１１と略同形状の金属製板材からなるベース２１と、このベース２１の上に固定される戸当り部材２５とを備えて構成されている。この戸当り本体２０において、扉が当接する側、すなわち、戸当り本体２０を固定部材１１に取り付けた状態で壁２の反対側となる側面が当接側面２０Ａとされている。
ベース２１は、固定部材１１の係合ピン１２と対応する位置に２つの係合孔２２を有し、また３つの角の近辺には、ねじ孔２３が設けられている。
ベース２１の係合孔２２の周辺部分は、図３に示すように、上面が上方に突出し、下面には波形座金１５が収まる凹みを形成するようにプレス加工されている。従って、係合孔２２の周辺部分以外のベース２１下面は、固定部材１１の上面と隙間なく密着するようになっている。
【００２０】
係合孔２２は、ベース２１を貫通して設けられており、係合ピン１２の頭部１２Ｂを挿通可能な孔径を有した大孔部２２Ａと、係合ピン１２の幹部１２Ａを挿通可能で、かつ頭部１２Ｂを挿通不能な孔径を有した小孔部２２Ｂとが連続して形成されている。また、係合孔２２は、その小孔部２２Ｂを当接側面２０Ａに向けて配置されている。
なお、大孔部２２Ａから小孔部２２Ｂに向かう方向は、当接側面２０Ａに対して略直交して配置しているが、これに限らず、係合孔２２の大孔部２２Ａから小孔部２２Ｂに向かう方向が当接側面２０Ａに対して傾斜する傾斜角度を０度から９０度の範囲に設定できる。
【００２１】
戸当り部材２５は、固定部材１１およびベース２１と平面略同形状のフランジ部２５Ａと、このフランジ部２５Ａから立ち上がる柱部２５Ｂとが一体に形成された、合成樹脂製の部材である。そして、戸当り部材２５は、フランジ部２５Ａの３つの角の近辺にそれぞれ設けられた挿通孔２９を挿通するねじ２８によってベース２１に固定されている。
なお、戸当り部材２５をベース２１に固定する方法は、ねじ止めに限らず、かしめや、嵌め込み、接着等の固定方法を採用できる。
【００２２】
戸当り部材２５の柱部２５Ｂの上端には、扉が当接する当接部材２６が当接側面２０Ａから突出して固定され、この当接部材２６を貫通してリング２７が回動自在に取り付けられている。
当接部材２６は、扉が当接する際の衝撃を緩和するための緩衝材としての機能を有するものであり、ゴムや合成樹脂等の弾性材料から形成されている。
リング２７は、金属製の棒材から曲げ加工により形成された、略環状の部材であって、このリング２７を扉側に回動し、扉に固定された図示しないフックに係止することにより、扉を開放状態位置に固定することができ、すなわち、戸当り１０がドアストッパーとして利用できる。
なお、戸当り１０をドアストッパーとして機能させるためには、戸当り１０にリング２７を取り付けることに限らず、戸当り１０にフックを取り付け、扉にリング状部材を取り付けることでもよい。
【００２３】
以上の構成を備える本実施形態の戸当り１０の取付方法について、以下に説明する。
先ず、床１に固定部材１１をビス止め固定する。この際、戸当り本体２０の取り付け後に当接側面２０Ａが壁２の逆側である扉側に向くように、固定部材１１の方向を合わせて固定する。
次に、戸当り部材２５をベース２１にねじ止め固定した戸当り本体２０の当接側面２０Ａが扉側に向くように方向を合わせながら、係合孔２２に係合ピン１２を挿通する。この際、ベース２１の底面に当接する波形座金１５の弾性力に抗しながら、係合ピン１２の頭部１２Ｂを係合孔２２の大孔部２２Ａに挿通する。
最後に、戸当り本体２０を所定の方向としての壁２に向かう方向Ａにずらすことで、幹部１２Ａが小孔部２２Ｂに挿通され、頭部１２Ｂが小孔部２２Ｂの縁を係止することとなる。
【００２４】
以上により戸当り本体２０は、ベース２１の底面を上方に付勢する波形座金１５により頭部１２Ｂと小孔部２２Ｂの縁とが圧着された状態で、固定部材１１に取り付けられる。
また、戸当り本体２０を壁２から離れる方向にずらし、すなわち、係合ピン１２を係合孔２２の小孔部２２Ｂから大孔部２２Ａに移動し、頭部１２Ｂを大孔部２２Ａから外すことで、戸当り本体２０を固定部材１１から取り外すことができる。
【００２５】
このような本実施形態によれば、次のような効果がある。
（１）　戸当り１０を固定部材１１および戸当り本体２０から構成し、床１に固定した固定部材１１に戸当り本体２０を着脱自在に取り付け可能としたことにより、掃除の際に必要に応じて容易に取り外すことができ、戸当り１０が邪魔にならず、戸当り１０の周辺まできれいに掃除することができる。
【００２６】
（２）　戸当り１０を固定部材１１および戸当り本体２０に、互いに係合する係合ピン１２および係合孔２２を設けるだけの単純な構造としたことにより、床１に孔や凹みを設ける必要がなく、取付施工や交換の作業が容易にできる。
【００２７】
（３）　係合ピン１２の頭部１２Ｂが係合孔２２の小孔部２２Ｂの縁を係止することにより、係合ピン１２の高さ寸法を１０ｍｍ以下と小さくしても係合状態を維持できるので、固定部材１１が邪魔にならず、固定部材１１を床１の任意の位置に取り付けられ、取付位置の自由度が高くできる。また、戸当り本体２０が固定部材１１から不用意に外れることがないので、戸当り１０の機能が損なわれることなく、扉の開き過ぎを防止できる。
【００２８】
（４）　係合孔２２の大孔部２２Ａから小孔部２２Ｂに向かう方向が当接側面２０Ａに対して傾斜する傾斜角度を０度から９０度の範囲に設定し、係合ピン１２の頭部１２Ｂが小孔部２２Ｂの縁を係止することにより、壁２から離れる方向以外の方向への戸当り本体２０の移動が規制されるので、戸当り１０に扉が当接しても、戸当り本体２０が固定部材１１から不用意に外れないようにできる。
【００２９】
（５）　係合ピン１２の頭部１２Ｂと係合孔２２の小孔部２２Ｂの縁とを圧着させる波形座金１５を備えることにより、戸当り本体２０と固定部材１１とのがたつきやずれを防止して、両者の取付状態を良好に維持できる。
【００３０】
（６）　床１に固定される固定部材１１に係合ピン１２を設けることにより、係合ピン１２の部分以外の固定部材１１の厚さ寸法を小さくでき、戸当り本体２０を外した状態において、固定部材１１の床１からの出張りを小さく邪魔にならないようにできる。また、ごみやほこりが溜まりやすい床側に係合孔２２を設けないので、ごみやほこりによる戸当り本体２０の着脱が困難になる不具合を回避できる。
【００３１】
（７）　係合ピン１２および係合孔２２をそれぞれ２つずつ設けることにより、戸当り本体２０を固定部材１１に取り付けた状態での係合ピン１２を中心とする戸当り本体２０の回転を防止できる。
【００３２】
〔第２実施形態〕
図４は、第２実施形態に係る戸当り３０を示す斜視図である。
第２実施形態に係る戸当り３０は、係合凸部および係合凹部の構成が、前述の第１実施形態の場合と異なるもので、その他の構成および取付方法は第１実施形態と同様である。従って、第１実施形態と異なる構成要件について、以下に説明する。
【００３３】
図４において、戸当り３０は、建物等の床１に固定される固定部材３１と、この固定部材３１に着脱自在に取り付けられる戸当り本体３５とを備えて構成されている。
戸当り本体３５は、金属製の板材からなるベース３６と、このベース３６の上に固定される戸当り部材２５とを備えて構成されている。この戸当り本体３５において、扉が当接する側が当接側面３５Ａとされている。また、戸当り部材２５は、前述の第１実施形態と同様の部材である。
ベース３６には、２つの平面略矩形状の係合孔３７が設けられている。
【００３４】
固定部材３１は、金属製の板材から形成され、その上面の係合孔３７と対応する位置には、係合凸部としての２つの係合爪３２が切り起こしにより形成されている。
係合爪３２は、固定部材３１の上面から上方に切り起こされた突出部３２Ａと、この突出部３２Ａの上端から略水平方向に延びる突片３２Ｂとを有している。この突片３２Ｂと固定部材３１の上面との間隔は、ベース３６の板材の厚さ寸法より若干小さくされ、突片３２Ｂの先端側は上方に曲げ上げられている。
【００３５】
以上の構成を備える本実施形態における戸当り３０の取付方法は、前述の第１実施形態の場合とほぼ同様であるが、異なる点についてのみ、以下に説明する。戸当り本体３５の当接側面３５Ａの方向を合わせながら、床１に固定された固定部材３１の係合爪３２に係合孔３７を挿通する。そして、係合爪３２の突片３２Ｂを係合孔３７の縁で上方に押し上げながら、戸当り本体３５を壁２に向かう方向Ａにずらすことで、突片３２Ｂが係合孔３７の縁を係止し、係合爪３２の弾性によってベース３６が固定部材３１に向かって押圧されることとなる。
【００３６】
このような本実施形態によれば、前述の（１）の効果に加えて、次のような効果がある。
（８）　戸当り３０を固定部材３１および戸当り本体３５に、互いに係合する係合爪３２および係合孔３７を設けるだけの単純な構造としたことにより、床１に孔や凹みを設ける必要がなく、取付施工や交換の作業が容易にできる。
【００３７】
（９）　係合爪３２の突片３２Ｂが係合孔３７の縁を係止することにより、係合爪３２の高さ寸法が小さくても係合状態を維持できるので、固定部材３１が邪魔にならず、固定部材３１を床１の任意の位置に取り付けられ、取付位置の自由度が高くできる。
【００３８】
（１０）　係合爪３２の弾性によってベース３６が固定部材３１に向かって押圧されることにより、戸当り本体３５の取付状態が維持され、固定部材３１から不用意に外れることがないので、戸当り３０の機能が損なわれることなく、安定して扉の開き過ぎを防止できる。さらに、別途弾性部を設けなくても、戸当り本体３５と固定部材３１とのがたつきやずれを防止して、両者の取付状態を良好に維持でき、部品点数や加工工数の削減を図ることができる。
【００３９】
（１１）　床１に固定される固定部材３１に係合爪３２を設けることにより、係合爪３２の部分以外の固定部材３１の厚さ寸法を小さくでき、戸当り本体３５を外した状態において、固定部材３１の床１からの出張りを小さく邪魔にならないようにできる。また、ごみやほこりが溜まりやすい床側に係合孔３７を設けないので、ごみやほこりによる戸当り本体３５の着脱が困難になる不具合を回避できる。
【００４０】
（１２）　係合爪３２および係合孔３７をそれぞれ２つずつ設けることにより、戸当り本体３５を固定部材３１に取り付けた状態での戸当り本体３５の回転を防止できる。
【００４１】
〔第３実施形態〕
図５は、第３実施形態に係る戸当り４０を示す斜視図である。
第３実施形態に係る戸当り４０は、係合凸部および係合凹部の構成が、前述の第１実施形態の場合と異なるもので、その他の構成は第１実施形態と同様である。従って、第１実施形態と異なる構成要件について、以下に説明する。
【００４２】
図５において、戸当り４０は、建物等の床１に固定される固定部材４１と、この固定部材４１に着脱自在に取り付けられる戸当り本体４５と、固定部材４１に取り付けられた弾性部としての波形座金１５とを備えて構成されている。
固定部材４１の上面には、第１実施形態と同様の係合凸部としての２つの係合ピン１２が壁２と略平行な方向に並べて突設されている。
【００４３】
戸当り本体４５は、金属製の板材からなるベース４６と、このベース４６の上に固定される戸当り部材２５とを備えて構成されている。この戸当り本体４５において、扉が当接する側が当接側面４５Ａとされている。また、戸当り部材２５は、前述の第１実施形態と同様の部材である。
ベース４６には、２つの係合孔４７が設けられている。これらの係合孔４７は、係合ピン１２の間隔を直径とする円周に沿って設けられ、係合ピン１２の頭部１２Ｂを挿通可能な大孔部４７Ａと、この大孔部４７Ａに連続する細長状の小孔部４７Ｂとを備えている。
【００４４】
以上の構成を備える本実施形態における戸当り４０の取付方法は、前述の第１実施形態の場合とほぼ同様であるが、異なる点についてのみ、以下に説明する。床１に固定された固定部材４１の係合ピン１２に係合孔４７の大孔部４７Ａを挿通する。そして、戸当り本体４５の当接側面４５Ａが扉の側になるように、戸当り本体４５を回転方向Ｂに回すことで、係合ピン１２の頭部１２Ｂが係合孔４７の小孔部４７Ｂの側に移動し、小孔部４７Ｂの縁を係止することとなる。
【００４５】
このような本実施形態によれば、前述の（１）〜（３）、（５）、（６）の効果に加えて、次のような効果がある。
（１３）　戸当り本体４５を回転方向Ｂに回転させて、係合孔４７の小孔部４７Ｂに係合ピン１２を挿通し、頭部１２Ｂで小孔部４７Ｂの縁を係止することにより、戸当り４０に扉が当接するような直線的な力の作用では、その当接方向に戸当り本体４５が移動せず、固定部材４１から不用意に外れることを防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a door stop that limits a range of a door opening operation.
[0002]
[Background Art]
To prevent the doors from opening too much, such as the handle or door knob attached to the door hitting the wall or window, etc., to prevent them from being damaged or the hinges supporting the door from being deformed or damaged, Door stops are known for limiting the range of the opening operation of the door.
Conventionally, such a door stop is fixed to a floor or a wall and abuts on an opened door to prevent the door from opening beyond the position where the door abuts. Normally, a cushioning material made of rubber or synthetic resin is provided in a portion that comes into contact with the door at the door stop in order to reduce an impact at the time of contact. Further, hooks and rings are provided at positions opposing each other on the door stop and the door contacting the door stop, and the engagement of these hooks and rings enables the door to be maintained in the open state. I have.
[0003]
However, since the door stop fixed to the floor or the wall is provided so as to protrude from the floor or the wall, there is an inconvenience that the door stop is obstructed during cleaning. In particular, when cleaning with a vacuum cleaner, a wide nozzle that is normally used hits a door stop, and the surrounding area cannot be cleaned, so it is necessary to replace the nozzle with a narrow nozzle for clearance, and cleaning is troublesome. Hang on.
As a door stop designed for the purpose of resolving such inconvenience, a door stop disclosed in Japanese Utility Model Laid-Open No. 6-1677 (conventional example 1) and a door stop disclosed in Japanese Patent Application Laid-Open No. 10-339067 ( Conventional example 2) has been proposed.
[0004]
The door stop of Conventional Example 1 is configured so as to be able to be stored under the floor surface, and has a tubular body embedded in the floor and a door stop which is stored in the cylindrical body and attached to be protrudable from the floor surface. And a coil spring for urging the door stop upward. Further, the door stop is provided with a mechanism for maintaining the stored state in which the door stop portion is stored in the cylindrical body and for releasing the stored state.
Therefore, in the door stop of the conventional example 1, since the door stop portion is stored in the cylindrical body, there is no portion protruding from the floor surface, so that the floor surface can be easily cleaned and the storage state of the door stop portion is released. By protruding from the floor, it can function as a door stop.
[0005]
The door stop of Conventional Example 2 is provided with a door stop member and a fixing member, and the fixing member is fixed to a floor surface and a wall surface, and the door stop member can be detachably attached to the fixing member. It is comprised in. That is, the fixing member is formed by bending a plate material to form an L-shape, is fixed by screws at the intersection of the floor surface and the wall surface, and the door stop member is formed having a concave portion, and the concave portion of the door stop member is formed. By fitting to the fixing member, the door stop member is detachably attached. The load when the door comes into contact with the door stop member is supported by the rising portion along the wall surface of the fixed member and the wall.
Therefore, in the door stop of the conventional example 2, since the door stop member can be detachably attached to the fixing member, the door stop member is detached from the fixing member at the time of cleaning, so that the door stop does not become an obstacle and it is easy to clean. it can.
[0006]
[Problems to be solved by the invention]
However, the door stop of Conventional Example 1 has a problem that the number of components such as the cylinder, the coil spring, the storage and release mechanism, and the like is large, the structure is complicated, and the manufacturing cost is increased. Furthermore, since it is necessary to embed the cylinder in the floor, a hole or a dent must be formed in the floor, and it takes time and effort to install the door stop, and there is a problem that replacement after the installation is difficult.
Further, in the door stop of the conventional example 2, since the L-shaped fixing member is fixed to the intersection of the floor surface and the wall surface to support the load against which the door abuts, when installed away from the wall surface, A member dimension that can support the load only at the rising portion of the fixing member is required. In other words, in order for the door stop member not to fall down, the rising portion of the fixing member needs to have the same height dimension as the door stop member. Will protrude from the Therefore, if the door stop of Conventional Example 2 is installed away from the wall surface, the above-described effect of not obstructing the cleaning can not be obtained, and the mounting position is limited.
[0007]
An object of the present invention is to provide a door stop which can be easily removed as required, has a simple structure, can be easily installed and replaced, and has a high degree of freedom in a mounting position.
[0008]
[Means for Solving the Problems]
The door stop of the present invention includes a fixing member fixed to a floor or a wall, and a door stop body detachably attached to the fixing member, and one of the fixing member and the door stop body includes the other. An engaging protrusion is provided for engaging with the engaging recess provided on the protrusion. The engaging protrusion includes a protrusion protruding toward the engagement recess, and a protrusion provided on a tip side of the protrusion. A projecting piece extending in a direction intersecting the projecting direction of the portion, wherein the engaging projection and the engaging recess are shifted in a predetermined direction from each other, and the projecting piece locks the engaging recess. The movement of the door stop body in a direction away from a floor or a wall to which the fixing member is fixed is restricted.
[0009]
Here, the "predetermined direction" in which the engaging convex portion and the engaging concave portion are displaced from each other is defined as a force acting when the door comes into contact with the door stop main body or an applied load such as the own weight of the door stop main body. It means a direction in which the door stop body does not easily come off the fixing member. That is, the direction in which the engaging projections and the engaging recesses are appropriately shifted can be set so that a load in a direction opposite to the direction in which the engaging projections and the engaging recesses are shifted from each other is not applied. Further, the “predetermined direction” may be one direction along a straight line, two or more directions including a bent portion in the middle, or a rotation direction along a curved line such as an arc.
[0010]
According to the present invention, the door stop is constituted by the fixing member and the door stop main body, and the door stop main body can be detachably attached to the fixing member fixed to the floor or the wall, so that the door stop is necessary for cleaning. Can be easily removed according to the requirements.
In addition, since the fixing member and the door stop body have a simple structure in which the engaging projections and the engaging recesses that engage with each other are simply provided, there is no need to provide holes or dents in the floor, so that installation and replacement can be performed. Work can be done easily.
Further, since the projection of the engagement projection locks the engagement recess, the engagement state can be maintained without increasing the dimensions of the engagement projection and the engagement recess, and the size of the fixing member can be reduced. Therefore, the fixing member can be attached to an arbitrary position on the floor or the wall without any hindrance, and the degree of freedom of the attaching position can be increased. Further, since the door stop main body is not accidentally detached from the fixing member, it is possible to prevent the door from being excessively opened without impairing the function as the door stop.
[0011]
Further, in the door stop of the present invention, a head in which the projecting piece is provided over the entire periphery of the projecting portion is formed at the tip of the projecting portion, and the engaging recess allows the projecting portion to be inserted. A small hole portion having a hole diameter through which the head cannot be inserted, and a large hole portion having a hole diameter through which the head can be inserted. By displacing the protruding portion and the head inserted into the portion in the direction of the small hole, the head locks the edge of the small hole.
In such a configuration, an engaging projection having a head formed by a protruding piece provided over the entire periphery of the distal end of the projecting portion, and an engaging hole in which a large hole and a small hole are formed continuously. By engaging, for example, by adopting a headed pin or the like as the engagement projection, the engagement projection can be formed more easily, and the edge of the small hole of the engagement hole is engaged with the head. By stopping, movement in a direction other than from the small hole to the large hole is restricted, and the door stop body can be more securely attached. In other words, by appropriately arranging the large hole portion and the small hole portion of the engagement hole in the direction in which an external force such as a force when the door comes into contact or an own weight is applied, the door stop body is inadvertently prepared from the fixing member. So that it does not come off.
[0012]
In the door stop according to the present invention, at least a part of the fixing member or the door stop main body provided with the engagement protrusion is formed of a plate-like member, and the protrusion and the protrusion of the engagement protrusion are provided. The piece is formed by bending a part of the plate-shaped member by cutting and raising, and the engagement recess is an engagement hole having a hole diameter through which the protrusion and the protrusion can be inserted. By inserting a protruding piece into the engaging hole and displacing the protruding piece in the extending direction of the protruding piece, a configuration can be adopted in which the distal end side of the protruding piece locks the edge of the engaging hole.
In such a configuration, by cutting and raising a part of the plate member constituting the fixing member or the door stop main body and forming the engagement projection by bending, another member is formed to constitute the engagement projection. There is no need to prepare, and the number of parts can be reduced. In addition, since the edge of the engaging hole is locked by the distal end side of the protruding piece, the movement of the door stop main body is regulated, and the attached state can be reliably maintained.
[0013]
Furthermore, the door stop of the present invention is characterized in that the door stop is provided with an elastic portion for pressing the door stop body and the fixing member.
Here, the elastic portion may be an elastic member as a separate member attached to the door stop body or the fixing member, or may be formed by processing a part of the door stop body or the fixing member. .
In such a configuration, by providing the door stop main body and the fixing member with an elastic portion for crimping, the door stop main body can be attached to the fixing member in close contact with the door stop main body and the fixing member. The displacement can be prevented, and the mounting state of both can be maintained well.
[0014]
Further, in the door stop according to the present invention, the engaging protrusion is provided on the fixing member, and the engaging recess is provided on the door stop main body.
In such a configuration, by providing an engaging protrusion on the fixing member fixed to the floor or the wall and providing the engaging recess on the door stop body, the thickness of the fixing member other than the portion provided with the engaging protrusion is provided. The size of the fixing member can be reduced, and the protrusion of the fixing member from the floor or wall can be reduced in a state where the door stop body is removed, so that the fixing member does not get in the way. In addition, since no engagement hole is provided on the floor or wall side where dust and dirt tend to accumulate, it is possible to avoid a problem that dust and dirt accumulate in the engagement hole and make it difficult to attach and detach the door stop body.
[0015]
