Description

【０００１】
【発明の属する技術分野】
本発明は、建築物の主に内装用ドアに用いられる戸当りの構造に関する技術分野に属する。
【０００２】
【従来の技術】
従来の戸当りの構造として、例えば図７に示すように、ドア枠３１の表面に断面略矩形状の取付条溝３５を形成する一方、戸当り３８は、半割り角筒状の戸当り本体３９と、この戸当り本体３９から連続して延び、上記取付条溝３５と略同じ形状の半割り角筒状の嵌合部４０とからなし、この嵌合部４０を取付条溝３５内に密嵌合して接着することで、戸当り３８を取付条溝３５に取付固定するようにしたものが一般によく知られている。４２は戸当り本体３９にドアと接触するように一体形成されたクッション部である。
【０００３】
しかし、この構造では、戸当り３８の嵌合部４０が取付条溝３５に密嵌合するよう戸当り３８の成形に高精度が要求される。しかも、その戸当り３８の嵌合部４０を取付条溝３５に嵌合した後、接着剤の固化のために長時間の養生時間が必要であった。
【０００４】
【発明が解決しようとする課題】
そこで、本出願人は前に、戸当りのドア枠への取付けを容易に行うとともに、戸当りを抜け難くした構造を提案している（特願平８−３３０６３９号明細書及び図面参照）。このものでは、図８（ａ）に示す如く（図７と同じ部分については同じ符号を付して説明する）、例えば、ドア枠３１を芯材３２とその表面に貼着される面材３３とで構成し、芯材３２に取付条溝３５の底部を、また面材３３に取付条溝３５の開口部をそれぞれ形成することにより、取付条溝３５を底部の溝幅が開口部よりも大きい中広形状として、その開口部両側縁を引掛かり部３６，３６とする。一方、戸当り３８は、その嵌合部底壁を戸当り３８の長手方向に切り欠いて隙間を設けることで、互いに平行な２条の脚部４１，４１を形成し、その脚部４１，４１外面に係止凸条４３，４３を設け、両脚部４１，４１を上記隙間を縮めるように両者間の幅を小さくしながら取付条溝３５内に嵌合し、その各係止凸条４３を取付条溝３５の開口部側縁の引掛かり部３６に係合させて戸当り３８を取付条溝３５から抜止めし、戸当り３８の嵌合取付けを容易に行い得るようにしている。
【０００５】
ところが、その場合、係止凸条４３と引掛かり部３６との係合によって戸当り３８を取付条溝３５から抜け難くしているものの、ドア閉時の大きな衝撃によって戸当り３８が変形して取付条溝３５から外れてしまう虞れがあり、改良の余地がある。
【０００６】
すなわち、図８（ａ）に示すように、戸当り３８に横方向からドア閉時の衝撃力Ｆがかかると、図８（ｂ）に示す如く、その衝撃力Ｆの作用する側とは反対側の脚部４１がドア枠３１表面を支点に回転するように変形し、この変形により図８（ｃ）に示すように上記衝撃力Ｆの作用側の脚部４１が取付条溝３５の開口部側縁から大きく離れて、その係止凸条４３の引掛かり部３６との係合が外れ、戸当り３８の脱落に至ることが判明した。
【０００７】
本発明は斯かる点に鑑みてなされたもので、その目的は、上記のように戸当りが脚部の係止凸条とドア枠の取付溝開口部側縁の引掛かり部との係合によって取り付けられている構造に限らず、単に戸当りが互いに間隔をあけた１対の脚部によりドア枠の取付溝に嵌合されている構造において、ドア閉時の衝撃力の作用により戸当りの脚部が回転変形して戸当りが取付溝から抜け落ちるのを確実に防止できるようにすることにある。
【０００８】
【課題を解決するための手段】
上記の目的の達成のため、この発明では、戸当りにおいてドア枠の取付溝に嵌合される１対の脚部の先端に互いに係止可能な係止片を設け、ドアからの衝撃力が戸当りに作用した際、係止片同士を係合させることで、脚部の回転変形を抑制するようにした。
【０００９】
具体的には、請求項１の発明では、ドア枠の取付溝に取り付けられる戸当りの構造が前提である。そして、上記戸当りは、戸当り本体と、該戸当り本体から互いに平行に間隔をあけて延出されて上記取付溝内に嵌合される２条の脚部とからなす。さらに、上記各脚部は、その先端から他の脚部側に向かって延びる底片と、該各底片の先端から取付溝の開口側に向かって延びかつ互いに隙間をあけて対向する係止片とを有するものとし、上記両係止片の対向する側にそれぞれ互いに係合可能な係合部を設ける。そして、上記係合部は、上記戸当りが取付溝へ取り付けられた状態で、上記ドアからの衝撃力の戸当り本体への作用によって上記係止片同士が接触したときのみに互いに係合するように構成する。
【００１０】
上記の構成により、戸当りが取付溝へ取り付けられただけの状態では、戸当りの脚部における係止片の係合部が係合しないが、ドアが戸当りに衝突してその戸当り本体にドアからの衝撃力が作用したとき、その衝撃力の作用する側とは反対側の部分の脚部がドア枠表面を支点として回転変形しようとすると、その初期に両脚部の底片先端に設けられている係止片同士が両者間の隙間のなくなるように接触して各々の係合部が係合し、この両係合部の係合によって係止片同士の相対移動が規制される。この状態では、それ以後の脚部の回転変形が阻止されるようになり、戸当りにおいてドアからの衝撃力作用側の脚部が取付溝の側縁から離れて取付溝への嵌合が外れることはなく、戸当りの脱落を確実に防止することができる。
【００１１】
請求項２の発明では、上記ドア枠の取付溝は、底部と該底部の溝幅よりも小さい幅を有する開口部とからなし、その開口部の両側縁に引掛かり部を設ける。さらに、戸当りの各脚部外面に、戸当りの長手方向に延びかつ脚部が取付溝に嵌合された状態で上記引掛かり部に引っ掛かって係止される係止凸条を設ける。
【００１２】
こうすると、戸当りの両脚部が取付溝に嵌合された状態では、その脚部外面の係止凸条が取付溝の開口部側縁の引掛かり部に係止されるので、戸当りがさらに外れ難くなる。尚、戸当りをドア枠に取り付けるときには、戸当りの戸当り本体ないし脚部の弾性を利用し、その両脚部を互いに近付けて両脚部間の間隔を小さくした状態で、脚部の係止凸条を取付溝の開口部に潜らせればよく、開口部の溝幅が底部よりも狭い中広の取付溝であっても、戸当りを容易に取り付けることができる。
【００１３】
請求項３の発明では、取付溝は、底側の溝幅が開口側よりも大きい断面略台形状の蟻溝とする。そして、戸当りの脚部を上記取付溝の蟻溝断面形状に対応した略台形状とする。このことで、上記請求項２の発明と同様の効果が得られる。
【００１４】
【発明の実施の形態】
（実施形態１）
図１は本発明の実施形態１に係る戸当り構造を示し、１は例えば上下方向に延びるドア枠で、このドア枠１は、芯材２と、該芯材２の前面（表面）から左右側面を経て後面（裏面）の左右側縁部に亘る範囲に貼着された面材３とからなる。これら芯材２及び面材３はいずれも木質材で、例えば合板や繊維板等が用いられる。特にＭＤＦ（中比重繊維板）を用いると、ルーター加工の際の加工性に優れているので好ましい。面材３の表面は、例えば塩化ビニールシート等でラッピングされたり或いは塗装されたりしていてもよい。
【００１５】
上記ドア枠１の前面（表面）の所定位置には、ドア枠１の長手方向に連続して延びる取付溝としての戸当り取付条溝５が凹設されている。この取付条溝５は、上記芯材２の前面に凹設されかつ底面の左右隅角部が円弧面とされた底部６と、該底部６の溝幅よりも小さい幅を有する開口部７とからなっていて、底側（内奥側）の溝幅が開口側よりも大きい中広形状とされており、上記開口部７の両側縁にそれぞれ面材３による引掛かり部８，８が形成されている。
【００１６】
上記ドア枠１に取付条溝５を形成する方法を図２により説明する。まず、図２（ａ）に示すように、面材３を貼り付ける前の芯材２を用意し、図２（ｂ）に示すように、その芯材２前面において後述の戸当り１１を取り付けようとする位置に、芯材２の長手方向に延びかつ戸当り１１の脚部１３，１３先端の係止凸条２１，２１を嵌挿可能な幅を有する、底部６となる条溝６′をルーター（図示せず）等により形成する。
【００１７】
次いで、図２（ｃ）に示す如く、上記芯材２の前面ないし後面の左右側縁部に面材３を上記条溝６′を覆うように貼着する。具体的には、芯材２の前面から後面左右側縁部までの長さの幅を有する板状の面材３に対して、その芯材２の前面及び後面の左右隅角部に対応する部位で切り欠いて断面Ｖ字状のＶ溝を形成し（Ｖカット）、この面材３を芯材２の前面ないし後面の左右側縁部を覆うようにＶ溝で断面コ字状に折り曲げて、その芯材２の前面ないし後面の左右側縁部に貼着する。
【００１８】
最後に、図２（ｄ）に示すように、上記芯材２前面の条溝６′に対応する位置の面材３を、ルーター等でその芯材２の条溝６′が外側に開口するように条溝６′の溝幅よりも狭い幅で長手方向に切削し、このことで開口部７を、またその両側に面材３からなる引掛かり部８，８をそれぞれ形成する。
【００１９】
図１に示す如く、上記ドア枠１の取付条溝５にはドア（図示せず）の閉じ位置を規制する戸当り１１が取付固定されている。この戸当り１１は、取付条溝５の開口部７の溝幅よりも大きい幅寸法を有する角筒状の戸当り本体１２を備え、この戸当り本体１２の後面（図１で下側面）には互いに平行に後方向に延出する２条の脚部１３，１３が一体に形成されている。これら戸当り本体１２及び脚部１３，１３は、若干の弾性を有する例えば硬質塩化ビニール樹脂等の硬質樹脂からなる。上記２条の脚部１３，１３は、上記取付条溝５内に嵌合されるもので、両脚部１３，１３間の幅寸法（間隔）は取付条溝５の開口部７の溝幅と略同じに設定されている。
【００２０】
上記各脚部１３の先端部外面には、戸当り１１の長手方向に連続して延びる１条の係止凸条２１が一体に形成されている。この各係止凸条２１における脚部基端側には脚部１３外面と直交する方向の平面からなる係止面２２が設けられており、戸当り１１の脚部１３，１３が取付条溝５に嵌合された状態では、脚部１３，１３外面の係止凸条２１，２１における係止面２２，２２がそれぞれ上記取付条溝５における開口部７両側縁の引掛かり部８，８に引っ掛かって係止される。各係止凸条２１における脚部１３先端側の面は、取付条溝５底面の左右隅角部に対応して円弧面とされている。
【００２１】
上記各脚部１３は、その先端から直角に相対向する他の脚部１３側に向かって延びる１対の板状の底片１４，１４と、この各底片１４の先端から取付条溝５の開口側（図１で上側）に向かって延びる１対の係止片１５，１５とを一体に有し、両係止片１５，１５間には隙間Ｇがあけられている。その一方（図１右側）の係止片１５には、他方（図１左側）の係止片１５と対向する側の面に、戸当り１１の長さ方向に延びる断面三角形状の１条の凸部１６（係合部）が、また他方の係止片１５には、一方の係止片１５と対向する側の面に戸当り長さ方向に延びかつ上記一方の凸部１６を係合可能な１条の凹部１７（係合部）がそれぞれ形成されている。
【００２２】
尚、戸当り１１の各脚部１３が取付条溝５に嵌合されて係止凸条２１の係止面２２が取付条溝５の開口縁の引掛かり部８に係止された状態では、戸当り本体１２の脚部１３への接続部１２ａがドア枠１の前面（面材３の前面）に対して所定寸法だけ浮き上がっており、この戸当り本体１２の弾性によりその脚部１３への接続部１２ａと係止凸条２１とをそれぞれドア枠１の面材３に圧接するように付勢して、両者間に面材３を挟み込み保持するようになっている。
【００２３】
また、上記係止凸条２１よりも基端側の脚部１３外面には、戸当り１１の長手方向に連続して延びる断面ジグザグ状の複数の凹凸部２３，２３，…が形成されており、戸当り１１の脚部１３が取付条溝５に嵌合された状態では、凹凸部２３，２３，…が取付条溝５の開口部７の側縁部に滑り止め状態で当接している。
【００２４】
したがって、この実施形態においては、ドア枠１の取付条溝５に戸当り１１を取り付けるとき、２条の脚部１３，１３が互いに接近して両底片１４，１４の先端部間の隙間Ｇがなくなるように戸当り１１を変形させながら、その両脚部１３，１３を取付条溝５内に嵌合する。このことで、各脚部１３外面の係止凸条２１が取付条溝５の開口部７を潜って底部６内に移動する。すなわち、このように脚部１３，１３が接近するように戸当り１１を変形させながら、その脚部１３，１３を取付条溝５に嵌合するので、中広溝状の取付条溝５であっても、係止凸条２１，２１を有する脚部１３，１３を容易に嵌合することができる。
【００２５】
そして、この戸当り１１の脚部１３，１３が取付条溝５に嵌合された状態では、上記脚部１３，１３先端外面の係止凸条２１，２１の係止面２２，２２がそれぞれ取付条溝５の開口部７側縁の引掛かり部８，８に係止される。また、上記２条の脚部１３，１３は互いに離隔して両底片１４，１４先端の係止片１５，１５間に隙間Ｇがあけられる。
【００２６】
その際、戸当り本体１２の脚部１３への接続部１２ａがドア枠１の前面（面材３の前面）に対して浮き上がって、戸当り本体１２の弾性によりその脚部１３への接続部１２ａと係止凸条２１とがそれぞれドア枠１の面材３に圧接する方向に付勢され、両者間に面材３が挟み込み保持されているとともに、各脚部１３外面の凹凸部２３，２３，…が取付条溝５の開口部７の側縁部に滑り止め状態で当接しているので、これらの相乗的な作用により、戸当り１１を取付条溝５から抜け難くして強固に取付固定することができる。
【００２７】
そして、このように戸当り１１が取り付けられている構造において、図３（ａ）に示す如く、ドアが閉時に戸当り１１に衝突してその戸当り本体１２にドアからの衝撃力Ｆが作用したとき、その衝撃力Ｆの作用する側とは反対側（図３で右側）の脚部１３がドア枠１前面を支点として回転変形しようとする。しかし、戸当り１１の各脚部１３に、その底片１４先端から取付条溝５の開口側に向かって延びる係止片１５が一体に形成され、この両係止片１５，１５の対向側にそれぞれ凹部１７及び凸部１６が形成されているので、上記回転変形の初期に、図３（ｂ）に示すように両係止片１５，１５同士が両者間に隙間Ｇのなくなるように接触して一方の係止片１５の凹部１７に他方の係止片１５の凸部１６が係合し、この凹部１７及び凸部１６間の係合によって係止片１５，１５同士の相対移動が規制される。このため、それ以後、図３（ｃ）に示すように、上記脚部１３が回転変形するのは阻止され、戸当り本体１２は衝撃力Ｆの作用する側が反対側の部分に接近するように若干だけ変形する。その結果、脚部１３外面の係止凸条２１が取付条溝５の開口部７側縁の引掛かり部８から外れることはなく、ドア枠１からの戸当り１１の脱落を確実に防止することができる。
【００２８】
また、図２に沿って説明した製造工程を採ることで、芯材２表面の底部６と面材３の開口部７とからなっていて引掛かり部８を持った中広２段構造の取付条溝５であっても簡易に製造することができる。
【００２９】
（実施形態２）
図４は本発明の実施形態２を示し（尚、以下の各実施形態では、図１と同じ部分については同じ符号を付してその詳細な説明は省略する）、取付条溝５の構造並びに戸当り１１の係止片１５の係合部の形状を変えたものである。
【００３０】
すなわち、この実施形態では、ドア枠１の取付条溝５における底部６は芯材２のみに形成されているが、開口部７は面材３のみならず芯材２の一部に亘っても形成されている。また、この取付条溝５における底部６の左右隅角部は底面及び側面が直角状に交差する直交断面とされている。尚、この取付条溝５を作る場合、上記実施形態１とは異なり、先に芯材２に面材３を貼着して両者を一体化した後、その面材３ないし芯材２の一部をルーターで切削して取付条溝５を加工すればよい。
【００３１】
そして、戸当り１１における各脚部１３先端の係止片１５には、対向する係止片１５側に、戸当り１１の長さ方向に連続して延びる断面ジグザグ状の複数の凹凸部１８，１９（係合部）が形成されており、両係止片１５，１５の凹凸部１８，１９は、各々の凹部分に相手側の凸部分を嵌合することで、互いに係合可能とされている。その他の構成は実施形態１と同様である。従って、この実施形態でも上記実施形態１と同様の作用効果を奏することができる。
【００３２】
（実施形態３）
図５は実施形態３を示す。この実施形態では、ドア枠１は、表面に塩化ビニールシート等のラッピングや塗装等で化粧が施された１つの板材のみからなり、その前面に取付条溝５の開口部７及び底部６が形成されている（この取付条溝５を作る場合、上記実施形態２と同様にルーターによる切削加工を行う）。
【００３３】
また、戸当り１１における脚部１３先端の一方（図５右側）の係止片１５には、対向する他方（図５左側）の係止片１５側に戸当り１１の長さ方向に連続して延びる断面半円弧状の１条の凸部１６（係合部）が、また他方の係止片１５には、対向する一方の係止片１５側に上記凸部１６を係合可能な１条の凹部１７（係合部）がそれぞれ形成されている。従って、この実施形態でも実施形態１と同様の作用効果を奏することができる。
【００３４】
（実施形態４）
図６は実施形態４を示す。この実施形態では、ドア枠１の面材３は、芯材２の前面（表面）から左右側面に亘る範囲に貼着されている。また、このドア枠１に形成される取付条溝５は、底側の溝幅が開口側よりも大きい断面略台形状の蟻溝とされている。
【００３５】
そして、戸当り１１の両脚部１３，１３は、上記取付条溝５の蟻溝断面形状に対応するように先端側に向かって互いに間隔が離れるように略台形状とされ、この各脚部１３の係止片１５には上記実施形態２と同様の凹凸部１８，１９（係合部）が形成されている。
【００３６】
この実施形態の場合、戸当り１１の両脚部１３，１３が取付条溝５に嵌合された状態では、その各脚部１３外面が取付条溝５の開口側側縁に引っ掛かって係止されるので、戸当り１１が外れ難くなる。よって、上記実施形態１と同様の作用効果を奏することができる。
【００３７】
尚、上記各実施形態では、中広２段構造や蟻溝形状の取付条溝５に戸当り１１を取り付ける場合について説明しているが、本発明は、断面矩形状の取付条溝（図７参照）に、上記実施形態の如き係止凸条２１のない戸当りを取付固定する場合にも適用することができる。
【００３８】
また、上記各実施形態における戸当り１１の本体１２にドアに当接するクッション部を突設してもよい。
【００３９】
【発明の効果】
以上説明したように、請求項１の発明によると、戸当りを、戸当り本体と、該戸当り本体から互いに平行に間隔をあけて延出されてドア枠の取付溝内に嵌合される２条の脚部とからなし、各脚部は、その先端から他の脚部側に向かって延びる底片と、該各底片の先端から取付溝の開口側に向かって延びかつ互いに隙間をあけて対向する係止片とを有する構成とし、両係止片の対向する側にそれぞれ互いに係合可能な係合部を設け、この係合部を、ドアからの衝撃力の戸当り本体への作用によって係止片同士が接触したときのみに互いに係合するものとしたことにより、ドアの閉時に戸当りに衝撃力が作用した際に、その戸当りの一方の脚部が回転変形しようとするのを係止片の係合部同士の係合によって阻止でき、戸当りの脱落を確実に防止して、安定した戸当り構造が得られる。
【００４０】
請求項２の発明では、ドア枠の取付溝は、底部と該底部の溝幅よりも小さい幅を有する開口部とからなし、その開口部の両側縁に引掛かり部を設ける一方、戸当りの各脚部外面に、戸当りの長手方向に延びる係止凸条を設け、戸当りの脚部が取付溝に嵌合された状態で係止凸条を引掛かり部に引っ掛かけて係止するようにした。また、請求項３の発明では、取付溝は、底側の溝幅が開口側よりも大きい断面略台形状の蟻溝とする一方、戸当りの脚部は取付溝の蟻溝断面形状に対応した略台形状とした。これらの発明によると、戸当りの脱落をさらに確実に防止することができる。

BACKGROUND OF THE INVENTION
The present invention belongs to a technical field relating to a door-to-door structure used mainly for interior doors of buildings.
[0002]
[Prior art]
As a conventional door stop structure, for example, as shown in FIG. 7, a mounting groove 35 having a substantially rectangular cross section is formed on the surface of the door frame 31. 39 and a fitting portion 40 that extends continuously from the door-to-door main body 39 and has substantially the same shape as the mounting groove 35 and has a half-square tube shape. It is generally well known that the door stop 38 is attached and fixed to the attachment groove 35 by closely fitting and adhering. Reference numeral 42 denotes a cushion portion integrally formed with the door-stop main body 39 so as to come into contact with the door.
[0003]
However, in this structure, high precision is required for molding the door stop 38 so that the fitting portion 40 of the door stop 38 is closely fitted in the mounting groove 35. And after fitting the fitting part 40 of the door stop 38 in the attachment groove | channel 35, long curing time was required for solidification of the adhesive agent.
[0004]
[Problems to be solved by the invention]
Therefore, the present applicant has previously proposed a structure in which the door is easily attached to the door frame and the door is difficult to come off (see Japanese Patent Application No. 8-330639 and the drawings). In this case, as shown in FIG. 8 (a) (the same parts as in FIG. 7 will be described with the same reference numerals), for example, the door frame 31 is a core member 32 and a face member 33 attached to the surface thereof. The bottom of the mounting groove 35 is formed in the core member 32, and the opening of the mounting groove 35 is formed in the face member 33, so that the groove width of the bottom of the mounting groove 35 is larger than that of the opening. As the large medium-wide shape, the both side edges of the opening portion are set as catch portions 36 and 36. On the other hand, the door stop 38 is formed by notching the fitting portion bottom wall in the longitudinal direction of the door stop 38 to provide a gap, thereby forming two parallel leg portions 41, 41. 41 is provided with locking projections 43, 43 on the outer surface, and both the leg portions 41, 41 are fitted into the mounting groove 35 while reducing the width between them so as to reduce the gap. Is engaged with the catch portion 36 on the side edge of the opening of the mounting groove 35 to prevent the door stop 38 from being pulled out of the mounting groove 35 so that the door 38 can be easily fitted and attached.
[0005]
However, in this case, although the door stop 38 is difficult to be removed from the mounting groove 35 by the engagement of the locking protrusion 43 and the hook portion 36, the door stop 38 is deformed by a large impact when the door is closed. There is a possibility that the mounting groove 35 may come off, and there is room for improvement.
[0006]
That is, as shown in FIG. 8A, when the impact force F when the door is closed is applied to the door stop 38 from the lateral direction, it is opposite to the side on which the impact force F acts as shown in FIG. The leg 41 on the side is deformed so as to rotate with the surface of the door frame 31 as a fulcrum, and this deformation causes the leg 41 on the working side of the impact force F to open the mounting groove 35 as shown in FIG. It was found that the engagement with the catching portion 36 of the locking ridge 43 was disengaged from the part side edge and the door stop 38 was dropped.
[0007]
The present invention has been made in view of such a point, and the object of the present invention is as described above, in which the door stop is engaged with the locking protrusion on the leg portion and the catching portion on the side edge of the mounting groove opening of the door frame. Not only in the structure attached by the door, but in the structure in which the door stops are simply fitted in the mounting groove of the door frame by a pair of legs spaced apart from each other, the door stops due to the impact force when the door is closed It is to be able to surely prevent the leg portion of the door from rotating and deforming and the door stop coming off from the mounting groove.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a locking piece that can be locked to each other is provided at the tip of a pair of leg portions that are fitted into the mounting groove of the door frame in the door contact, and the impact force from the door is reduced. When acting on the door stop, the engaging pieces are engaged with each other to suppress the rotational deformation of the legs.
[0009]
Specifically, the invention of claim 1 is based on a door-to-door structure that is attached to the attachment groove of the door frame. And the said door stop consists of a door stop main body and two leg parts extended from the said door stop main body at intervals mutually parallel, and being fitted in the said attachment groove | channel. Further, each of the leg portions includes a bottom piece extending from the tip end toward the other leg side, and a locking piece extending from the tip end of the bottom piece toward the opening side of the mounting groove and facing each other with a gap therebetween. And engaging portions that can be engaged with each other are provided on opposite sides of the both locking pieces. The engaging portions engage with each other only when the locking pieces come into contact with each other by the action of the impact force from the door on the door-stop main body with the door-stop attached to the mounting groove. Configure as follows.
[0010]
With the above configuration, when the door stop is simply attached to the mounting groove, the engaging portion of the locking piece in the leg portion of the door does not engage, but the door collides with the door stop and the door stop main body. When the impact force from the door is applied to the door, if the leg portion on the opposite side of the impact force acts on the door frame surface as a fulcrum, it is provided at the beginning of the bottom piece of both legs at the initial stage. The engaging pieces are brought into contact with each other so that there is no gap between them and the respective engaging portions are engaged, and the relative movement of the engaging pieces is restricted by the engagement of both engaging portions. In this state, the rotational deformation of the legs thereafter is prevented, and the leg on the impact force acting side from the door is separated from the side edge of the mounting groove in the door contact, and the fitting to the mounting groove is released. It is possible to prevent the door from falling off without fail.
[0011]
According to a second aspect of the present invention, the door frame mounting groove includes a bottom portion and an opening portion having a width smaller than the groove width of the bottom portion, and hook portions are provided on both side edges of the opening portion. Furthermore, a locking ridge that extends in the longitudinal direction of the door stop and is hooked and locked by the hook portion in a state where the leg portion is fitted in the mounting groove is provided on the outer surface of each leg portion of the door stop.
[0012]
In this way, in a state where both leg portions per door are fitted in the mounting groove, the locking protrusion on the outer surface of the leg portion is locked to the catch portion on the opening side edge of the mounting groove. Furthermore, it becomes difficult to come off. When attaching the door stop to the door frame, make use of the elasticity of the door stop body or leg part of the door and keep the legs close to each other to reduce the distance between the leg parts. It is only necessary to immerse the strip in the opening of the mounting groove, and the door stop can be easily mounted even if the groove width of the opening is a medium-wide mounting groove narrower than the bottom.
[0013]
In the invention of claim 3, the mounting groove is a dovetail groove having a substantially trapezoidal cross section with a groove width on the bottom side larger than that on the opening side. And let the leg part per door be the substantially trapezoid shape corresponding to the dovetail cross-sectional shape of the said attachment groove | channel. Thus, the same effect as that of the second aspect of the invention can be obtained.

Then, the leg 13 on the side opposite to the side on which the impact force F acts (the right side in FIG. 3) tries to rotate and deform with the front surface of the door frame 1 as a fulcrum. However, each leg portion 13 of the door stop 11 is integrally formed with a locking piece 15 extending from the tip of the bottom piece 14 toward the opening side of the mounting groove 5, and on the opposite side of the both locking pieces 15, 15. Since the concave portion 17 and the convex portion 16 are respectively formed, at the initial stage of the rotational deformation, as shown in FIG. 3B, the locking pieces 15 and 15 come into contact with each other so that there is no gap G therebetween. The convex portion 16 of the other locking piece 15 is engaged with the concave portion 17 of the one locking piece 15, and the relative movement between the locking pieces 15, 15 is restricted by the engagement between the concave portion 17 and the convex portion 16. Is done. For this reason, thereafter, as shown in FIG. 3C, the leg 13 is prevented from being rotationally deformed, and the door-stop main body 12 is arranged so that the side on which the impact force F acts approaches the opposite side portion. Only slightly deformed. As a result, the locking projection 21 on the outer surface of the leg 13 does not come off from the hooking portion 8 on the side edge of the opening 7 of the mounting groove 5, and the door stopper 11 is reliably prevented from falling off from the door frame 1. be able to.
