Description

【０００１】
【発明の属する技術分野】
本発明は戸当り装置の床面用部材及び戸当り装置の改良に係り、更に詳しくは、床面用部材を設置する際に床面に嵌合凹部を形成せずに設置できるようにし、また、床面用部材の可動部材の動きによって生じる音を低減すると共に、可動部材が扉を停止させたときの衝撃も緩和することができるようにしたものに関する。
【０００２】
【従来技術】
扉を設ける場合、壁近傍の床面には、通常、扉を開いたときに壁と衝突して互いに損傷しないようにする戸当り装置が設置されている。
【０００３】
このような戸当り装置としては、例えば、特開平１１−２８７０６２号公報に開示されたようなものが知られている(図１５，図１６参照)。
この戸当り装置は、床面に設置して使用する床面用部材８と、扉の下部側に取り付けて使用する扉用部材９とを備え、床面用部材８の可動部材８０が、扉用部材９に備えられた磁石９０の磁力により起き上がって停止面９１と係合することで、扉を所定の位置で停止させるものである。
【０００４】
【発明が解決しようとする課題】
上記した戸当り装置は、次の点で一層の改良が求められていた。
(1) 床面用部材８は、可動部材８０の基部側がクランク状に折り曲げて形成してあるので、床面用部材８の裏面には可動部材８０の軸部８００を収容するための凸部８１が形成される。そのため、床面用部材８を設置する際には、床面にこの凸部８１を埋め込む嵌合凹部８５を床面を削って形成する必要がある。嵌合凹部８５を誤った位置に形成した場合は、その部分の床板を新しいものに交換するしか補修ができない。
また、床面に嵌合凹部を形成するので、施工の迅速性にも欠けていた。
【０００５】
(2) 可動部材８０が、磁石９０によって瞬時に起き上がって扉用部材９と当たった際に衝撃音が生じており、この音の低減策が求められていた。
また、扉を停止させる際に、可動部材８０と停止面９１とが直接当たっており、床面用部材８や扉用部材９に相当な衝撃が加わっていたので、この緩和策も求められていた。この際にも衝撃音が生じており、この音の低減策も求められていた。
更には、可動部材８０が起き上がった状態から倒れたときにも、可動部材８０が床面用部材８に当たって衝撃音が生じており、この音の低減策も求められていた。
【０００６】
ところで本発明者は、床面に凸状物として形成される床面用部材の厚みについて、実用上支障が少ない厚みを導き出す実験を行っていた。そして、前記実験を重ねることにより、床面用部材の厚みが５ｍｍを越えるものについては、例えば、車椅子の車輪の乗り上がりが困難になったり、歩行時に躓き易くなったりする傾向が見られたので、実用的でないことが分かった。
【０００７】
本発明の目的は、床面に嵌合凹部を形成せずに設置できるようにする戸当り装置の床面用部材及び戸当り装置を提供することにある。
また、本発明の他の目的は、可動部材が扉用部材や床面用部材と当たったときに生じる衝撃音を低減したり、扉を停止させたときの衝撃を緩和したりする戸当り装置の床面用部材及び戸当り装置を提供することにある。
更に、本発明の他の目的は、床面に設置した床面用部材によって、例えば、車椅子の車輪の乗り上がりが困難になったり、歩行時に躓き易くなったりしない戸当り装置の床面用部材及び戸当り装置を提供することにある。

【００２０】
「床面への設置面が平面である」という用語は、設置面が平面である場合や、厳密には平面でなくても設置にあたっては平面として取り扱っても支障がない場合を含む概念として使用している。
【００２１】
「板状の可動部材」という用語は、可動部材が板状である場合や、厳密には板状でなくても板状として取り扱っても支障がない場合を含む概念として使用している。
【００２２】
「基部材の上面と可動部材の上面は面一である」という用語は、基部材の上面と可動部材の上面が面一である場合や、厳密には面一でなくても面一として取り扱っても支障がない場合を含む概念として使用している。
【００２３】
「可動部材と基部材が当たる」という用語は、可動部材と基部材が直接当たる場合や、可動部材と基部材が間接的に当たる場合も含む概念として使用している。
【００２４】
基部材を成形する非磁性材料としては、例えば、亜鉛、真鍮、アルミニウム、マグネシウム、チタン、ステンレス、合成樹脂、陶磁器、これらを含んで形成してある材料等を挙げることができる。また、これらの表面は、メッキや塗装や合成樹脂で被覆することもできる。
【００２５】
（作用）
戸当り装置の床面用部材及び戸当り装置は次のように作用する。
扉用部材は、扉の下側に固定手段等を用いて設置される。床面用部材は、扉用部材の軌道上の床面に設置位置を決め、そのまま固定手段等を用いて設置される。
【００２６】
扉を開いて床面用部材が設置された位置まで動かすと、磁力によって可動部材が瞬時に起き上がり、停止手段と係合して扉は停止する。
【００２７】
扉を閉じると、可動部材は停止手段より外れて倒れ、可動部材収容凹部内に収容される。その際、衝撃音が発生するが、衝撃音低減手段を備えた床面用部材では、その衝撃音を低減することができる。
【００２８】
基部材の厚みが５ｍｍ以下に設定してある床面用部材は、例えば、車椅子の車輪の乗り上がりが困難になることもなく、歩行時に躓き易くなることもない。
【００２９】
可動部材が板状体を打ち抜いて形成してある床面用部材は、角に別途丸みを形成する工程が不要であり、その分製作時間の短縮が図れる。
【００３０】
可動部材の起立角度制限手段を有する床面用部材は、可動部材が直立した状態を維持する角度まで回動しないので、可動部材は起き上がらせていた力がなくなれば、自重で倒れて可動部材収容凹部に収容される。
【００３１】
基部材が非磁性材料で形成されている床面用部材は、基部材が磁化せず、起立手段による作用が妨げられることがない。
【００３２】
衝撃音低減手段を備えている戸当り装置では、可動部材が瞬時に起き上がって扉用部材に当たったときの衝撃音が低減する。
【００３３】
剥離防止手段が備えてある戸当り装置は、可動部材が衝撃音低減手段に当たった状態で扉を動かしても衝撃音低減手段が剥がれない。
【００３４】
衝撃緩和手段が設けてある戸当り装置は、扉を停止させたときに衝撃緩和手段が変形して衝撃を緩和する。また、衝撃の緩和により衝撃音も低減する。
【００３５】

戸当り装置は、床面６の表面に設置される床面用部材Ｋと、扉７の下端面に取り付けられる扉用部材Ｔ１とを備えている。なお、図１において扉７は、扉用部材Ｔ１を説明するための便宜上、想像線で示している。
【００３６】
床面用部材Ｋは、平面視において外形が略円形状に形成してある薄板状の基部材１を備えている。基部材１の上部側の外周緑には、全周にわたり面取加工が施してある。また、基部材１には上面から裏面に貫通した貫通穴１０，１０が所要間隔を設けて２箇所に形成してある。各貫通穴１０の内縁にはざぐりが設けてある。貫通穴１０，１０には、床面用部材Ｋを床面６に固定するための木ネジＮ１が通して設けてある(図１，図２，図３参照)。本実施の形態で基部材１は、約３．５ｍｍの厚みに形成してあるが、基部材の厚みはこれに限定するものではなく、上記した理由により５ｍｍ以下であるものが好ましい。
【００３７】
基部材１の略中央部には、上面の一部をやや凹ませて可動部材収容凹部１１が形成してある。可動部材収容凹部１１には、薄板状の可動部材２が収容してある。可動部材２については後述する。
【００３８】
可動部材収容凹部１１は、平面視において一方の短辺が円弧を描く曲線状に形成してある略長方形状を有している。可動部材収容凹部１１は、所要の幅を有し、基部材１の直径よりもやや短い長さを有する大きさに形成してある。本実施の形態で基部材１の直径（裏面）は、略７０ｍｍに設定してある。また、可動部材収容凹部１１は、幅が略２１．４ｍｍ、長さが略６０．２ｍｍ（中央部分）に設定してある。しかし、基部材１及び可動部材収容凹部１１の大きさは、これに限定するものではなく、適宜設定できる。
【００３９】
基部材１の形状も平面視において略円形状のものに限定せず、例えば、平面視において略楕円形状、略三角形状、略正方形状、略長方形状、略多角形状等を有するものが使用できる。また、可動部材収容凹部１１の形状も略長方形状のものに限定せず、例えば、平面視において略円形状、略楕円形状、略三角形状、略正方形状、略多角形状等を有するものが使用できる。
【００４０】
可動部材収容凹部１１の底部は平面状に形成してある。可動部材収容凹部１１の底部には、横倒時の可動部材２の裏面が載置される。可動部材収容凹部１１は、可動部材２の厚みよりもやや深く、収容された可動部材２の上面が基部材１の上面より僅かに凹んだ状態になる深さにしてある。しかし、この凹み幅は極僅かである。そのため可動部材２の上面と基部材１の上面は、面一として取り扱っても支障がない。
【００４１】
可動部材収容凹部１１の基部側の底部には、裏面と貫通した長方形状の可動部材挿入口１２が形成してある。
【００４２】
基部材１の裏面は床面６への設置面であり、略平面状に形成してある。裏面における可動部材挿入口１２の短辺側の両方には、可動部材２に形成してある軸部２０，２０を収容する軸部収容凹部１３，１３が、裏面から凹ませて可動部材挿入口１２と連なるようにして形成してある。
【００４３】
軸部収容凹部１３，１３の外端側は底面視において半円弧状に形成してあり、可動部材２が扉７を停止させたときの衝撃による応力が集中してかかることによる割れ等が生じにくくなっている。（例えば、外端側が角部を有する形状に形成してある場合では、上記衝撃による応力が、この角部に集中してかかるので、ここから割れやひびが生じることがある)。
【００４４】
また、可動部材挿入口１２及び軸部収容凹部１３，１３の上方には、傾斜面を有するストッパー部１２０が、基部材１の上面から可動部材収容凹部１１側にやや張り出して形成してある（図５，図６，図７，図８，図９参照)。ストッパー部１２０は、可動部材２の起き上がりを鋭角の所要角度で止める起立角度制限手段を構成する。
【００４５】
裏面側において可動部材挿入口１２及び軸部収容凹部１３，１３の周りには、裏面をやや凹ませて、裏蓋３を嵌め込むための裏蓋収容凹部１４が形成してある。裏蓋収容凹部１４は、裏蓋３を嵌め込んだときに、裏蓋３の下面が基部材１の裏面より僅かに凹んだ状態になる深さにしてある。
【００４６】
裏蓋収容凹部１４内には、嵌め込んだ裏蓋３を取り付けるための係合凸部１５が３箇所に形成してある。各係合凸部１５は、基部材１の裏面よりやや突出する程度の高さを有し、かつ、周面に先細り状のテーパーを有するように形成してある(図９参照)。
【００４７】
本実施の形態で示す基部材１は、非磁性材料である亜鉛合金を鋳型に流し込んで成形した鋳造品である。しかし、基部材を形成する材料は、これに限定するものではなく、例えば、磁性材料である鉄、銅等の金属（表面がメッキや塗装や合成樹脂で被覆してあるものを含む）等を使用することもできる。しかし、非磁性材料でつくることが好ましい。また、基部材の製造方法も鋳造に限定せず、例えば、プレス加工や削り出し等によっても形成できる。
【００４８】
可動部材２は、昇降部２１と、昇降部２１の回動の中心となる軸部２０，２０を備えている。昇降部２１は、可動部材収容凹部１１に略隙間無く収容されるように、平面視において一方の短辺が、可動部材収容凹部１１に形成された円弧を描く曲線と略同一曲率を有するような略長方形状に形成してある。軸部２０，２０は、昇降部２１の基端部の両側部に、側方に突出して形成してある。
【００４９】
可動部材２は、約１．６ｍｍの厚みを有する磁性材料である鉄製の板状体をプレスにより打ち抜いて形成してある。これにより可動部材２は平板状で軸部２０，２０と昇降部２１が一体になっている。また、可動部材２は、打ち抜きによって、打ち込み側の緑部の角が丸く形成してある。打ち込み側と反対の側の緑部は、バリ取り加工が施されて、打ち込み側と略同じように角がやや丸く形成してある。このように基部側の角が丸く形成してあることにより、角が基部材１に当たって起き上がらなくなることがない。
【００５０】
本実施の形態でバリ取りは、打ち抜いた可動部材２を入れた容器を回転または振動させて表面の仕上げを行うバレル加工で行っている。しかし、バリ取りの方法は、これに限定するものではない。このように可動部材２の緑部は角が丸く形成してあるが、丸くする方法が上記方法によるので、緑部が円弧状に形成されることはなく、角の間には依然として平面部が残されている（図６，図７参照）。しかしながら、緑部の形状はこれに限定するものではなく、円弧状に形成することもできる。
【００５１】
図４において下側にあたる可動部材２の軸部２０には、緩衝性及び伸縮性を有するポリエチレン製の管状体からなる緩衝材２２が、周面部を被覆するように差し込んで設けてある。緩衝材２２は、伸びた状態で軸部２０の全周にわたり、軸部２０に薄膜を形成するように設けてある（図４，図６，図７参照）。緩衝材２２は、起き上がり状態の可動部材が倒れて基部材と当たったときの衝撃音を低減する衝撃音低減手段構成する。
【００５２】
可動部材２は、基部材１の裏面側から可動部材挿入口１２に挿入して、基端部がストッパー部１２０の下方に位置するように軸部２０，２０を軸部収容凹部１３，１３に収容し、昇降部２１を可動部材収容凹部１１に略隙間無く収容することで、基部材１と一体に組まれている。可動部材２は、可動部材収容凹部１１に収容した状態で、緩衝材２２の上部が変形してストッパー部１２０と接触しており、緩衝材２２の下部が裏蓋の上面と接触している（図６参照）。
【００５３】
本実施の形態で可動部材２は、幅が略２１ｍｍ、長さが略５９．８ｍｍに設定してある。しかし、可動部材２の大きさはこれに限定せず、可動部材収容凹部１１の大きさによって適宜設定できる。
また、本実施の形態で示す可動部材２は、板状体を打ち抜いて形成したが、可動部材の形成方法はこれに限定するものではない。可動部材は、鋳造や削り出し等で製造もできる。
【００５４】
本実施の形態で可動部材２は、鉄製の板状体で、表面に錆防止及び外観の向上のためにメッキを施したものを使用した。しかし、可動部材は、後述するように磁石４５に磁着可能であれば良く、その材質は特に限定するものではない。可動部材は、磁着可能な金属を含むように形成してあれば良い。
【００５５】
また、緩衝材は、本実施の形態で示すものに限定するものではなく、可動部材２が倒れて基部材１に当たったときの衝撃音が低減できれば、形成する材料や形状、設ける箇所や設ける方法は、特に限定するものではない。緩衝材を形成する材料としては、例えば、他の合成樹脂類（例えば、（発泡）ポリウレタン樹脂等）、ゴム、塗料、オイル（グリースを含む）、不織布、コルク等が使用できる。また、例えば、図１２に示すような箇所に設けることもできる。なお、図１２で示すものについては後述する。更に、緩衝材は、接着、嵌め込み、付着（塗布、ディッピング）、貼着等により設けることもできる。
【００５６】
本実施の形態で緩衝材２２は、予め定めた一方の軸部２０のみに設けたが、両方の軸部２０，２０に設けることもできる。なお、緩衝材２２を設ける軸部２０の側を予め定めたのは、保守管理を容易にするためである。
【００５７】
裏蓋収容凹部１４には裏蓋３が取り付けてある。裏蓋３には、係合凸部１５と対応する箇所に係合孔３０が形成してある。裏蓋３は、金属製の板状体をプレスを打ち抜いて形成してある。しかし、裏蓋３は鋳造や削り出し等により製造することもできる。
【００５８】
裏蓋３は、各係合孔３０を対応する係合凸部１５に合わせて裏蓋収容凹部１４に嵌め込み、係合孔３０を通過して突出した係合凸部１５の先端をハンマー等で叩きつぶして径を拡げ、裏蓋収容凹部１４から外れないように取り付けてある。可動部材挿入口１２と軸部収容凹部１３，１３は、裏蓋３を裏蓋収容凹部１４に取り付けることで塞がれて、外部から見えない。
【００５９】
扉用部材Ｔ１は、平面視において外形が略長円形状に形成してある基部材４を備えている。基部材４の両側の略半円部分は、下緑部を除いてやや径が小さく形成してある。また、基部材４の両側の下縁部には、外方に張り出したフランジ部４０，４０が形成されている。
【００６０】
基部材４には、上面から裏面に貫通した貫通穴４１，４１が所要間隔を設けて２箇所に形成してある。各貫通穴４１の下側の内縁にはざぐりが設けてある。貫通穴４１，４１には、扉用部材Ｔ１を扉に固定するための木ネジＮ２が通して設けてある（図１参照）。
【００６１】
基部材４の裏側には、可動部材２が起き上がったときに昇降部２１が磁着する磁着面４２と、停止手段である停止面４３が形成してある(図２，図３，図１０参照）。磁着面４２と停止面４３は、共に傾斜して形成してある。磁着面４２の下部側は、横方向に拡がり、起き上がった昇降部２１が磁着面４２に磁着し易いように形成してある（図１０参照)。
【００６２】
また、基部材４には、略円形状を有する磁石収容凹部４４が磁着面４２の表面より内方に凹ませて形成してある。磁石収容凹部４４には起立手段である磁石４５が収容してある。磁石４５は下面が磁着面４２の表面と略面一に収容してある。
【００６３】
停止面４３には、衝撃緩和手段である緩衝材４６が設けてある。緩衝材４６は、所要厚みを有し、表面が平面状に形成してあるゴム製のものを使用しており、接着剤により張り付けてある。なお、緩衝材４６の表面は、例えば、凹凸状や波形状に形成することもできる。
【００６４】
また、磁着面４２の表面には、音を低減する衝撃音低減手段である緩衝板４７が設けてある。緩衝板４７は、薄板状のゴム板を使用しており、接着剤により張り付けてある。緩衝板４７は、中央部分における磁着面４２の全幅にわたる箇所に、溝部４７０が形成されている。（図１０参照）。
【００６５】
本実施の形態で示す基部材４は、非磁性材料である亜鉛合金を鋳型に流し込んで成形した鋳造品である。しかし、基部材を形成する材料は、これに限定するものではなく、例えば、磁性材料である鉄等の金属（表面がメッキや塗装や合成樹脂で被覆してあるものを含む）等を使用することもできる。また、基部材の製造方法も鋳造に限定せず、例えば、プレス加工や削り出し等によっても形成できる。
【００６６】
本実施の形態で磁石４５は、下面が磁着面４２の表面と略面一になるように設けたが、磁石４５の取り付け状態は限定するものではない。磁石は、昇降部２１を起き上がらせることができればよい。従って、この機能を満たすことができれば、例えば、磁石と昇降部２１との間に所要の部材を介在させることもできるし、磁着面４２より凹ませて設けることもできるし、凸部を形成するように設けることもできる。また、通常、磁石４５は永久磁石が使用されるが、これも限定せず、例えば、電磁石も使用できる。
【００６７】
本実施の形態で緩衝材４６や緩衝板４７は、ゴム製のものを使用したが、形成する材料や設ける方法は、特に限定するものではない。材料としては、例えば、他の合成樹脂類（例えば、（発泡）ポリウレタン樹脂等）、塗料、不織布、コルク等、各種緩衝性を備えたものを使用することもできる。また、嵌め込み、付着（塗布、ディッピング）、貼着等により設けることもできる。更に、緩衝板については、例えば、起き上がって扉用部材Ｔ１に当たる可動部材２の所要位置に設けてもよい。
【００６８】
（作用）
図１ないし図１０を参照して本発明の第１の実施の形態の作用を説明する。
扉用部材Ｔ１と床面用部材Ｋを、扉７と床面６にそれぞれ設置する。
扉用部材Ｔ１は、扉７の下端面に予め形成しておいた凹部に嵌め込んで、木ネジＮ２，Ｎ２を貫通穴４１，４１に挿通させてねじ込んで取り付けられる。扉用部材Ｔ１は、昇降部２１の先端が緩衝材４６に係合したときに、昇降部２１と磁着面４２とが略同じ傾斜角度を有し、昇降部２１の上面が磁着面４２に磁着する高さ位置に設置してある。
【００６９】
また、本実施の形態において扉用部材Ｔ１は、フランジ部４０，４０を下端面に引っ掛けて、フランジ部４０，４０の厚み分だけ下端面より張り出すようにして設置した。しかし、扉用部材Ｔ１の取り付けは、これに限定せず、機能上支障がなければ、扉７の下端面と面一になるように設置することもできるし、下端面より凹ませて設置することもできる。
【００７０】
床面用部材Ｋは、可動部材２の形状を軸部２０，２０が基部側の側方に突出した平板状に形成したので、従来の床面用部材の裏面に形成されていたような凸部を不要にでき、裏面が略平面状に形成できた。
更に、可動部材２を平板状に形成したことにより、これを収容する基部材１の厚みも薄くできた。これにより設置した際に床面６上に設けられる部分は、従来の床面用部材ほどではないが、実用上支障のない程度まで薄くできた。
【００７１】
従って、床面用部材Ｋは、扉用部材Ｔ１の軌道上の床面６に設置位置を決め、木ネジＮ１，Ｎ１を貫通穴１０，１０に挿通させて床面６にねじ込んで、床面用部材Ｋの上面が床面６の表面と略面一にして取り付けられる。
【００７２】
このように床面用部材Ｋは、従来形成していたような嵌合凹部を形成せずに床面６に設置できる。このため誤った位置に設置した場合でも、床板を新しいものに交換することなく、簡単に設置し直すことができる。また、設置が簡単になるので、施工も迅速になる。
【００７３】
扉７を、床面用部材Ｋが設置された位置まで開くと、磁石４５の磁力により昇降部２１が引き寄せられ軸部２０，２０を中心として瞬時に起き上がる。
【００７４】
起き上がった昇降部２１は、先部側の上面が緩衝板４７の下部側に当たって磁着面４２に磁着する。昇降部２１は、起き上がって緩衝板４７に当たるので、磁着面４２に当たったときの衝撃音が低減できる。
【００７５】
そして、昇降部２１は、扉７が開かれるにつれて、上面が緩衝板４７の下部側と擦れ合いながら僅かに上昇する（図２参照）。なお、昇降部２１の先端は、緩衝材４６に当たるまでは、緩衝板４７に当たらない。
【００７６】
扉７が開かれるにつれて上昇した昇降部２１の先端は、緩衝材４６に当たって係合する。これにより扉７は動きが止められ停止する。昇降部２１は先端が緩衝材４６に係合することにより、磁着面４２と略同じ傾斜角度で傾斜し、上面が緩衝板４７の表面に当たって磁着面４２に磁着する（図３参照）。
【００７７】
このように昇降部２１の先端が緩衝材４６に係合することで扉７が停止するので、扉７が停止したときの可動部材２と扉用部材Ｔ１に加わる衝撃を緩和することができ、戸当り装置の寿命を延ばすことができる。また、衝撃が緩和されることにより、衝撃音も低減できる。
【００７８】
なお、図３で示す可動部材２は、床面から略１９度の角度で傾斜している。しかし、可動部材２が緩衝材４６と当たる角度は、これに限定するものではなく、床面用部材Ｋと扉用部材Ｔ１の上下の間隔により変わる。
【００７９】
磁着面４２と磁着した可動部材２は、磁力によりこの状態が維持される。これにより扉７も所定の位置で停止した状態が維持される。
【００８０】
扉７の停止した状態を解除するときは、扉７を閉じる方向へ動かせば良い。扉７を閉じる方向へ動かすことにより、磁着面４２の下部側が昇降部２１を押し下げ、これにより磁着状態が解除される。そして、可動部材２は、倒れて可動部材収容凹部１１内に収容される。
【００８１】
可動部材２が倒れて可動部材収容凹部１１に収容されるときには、緩衝材２２がストッパー部１２０と裏蓋３に接触して変形した状態となるので、緩衝材２２によって可動部材２が基部材１と当たったときの振動が抑えられ、衝撃音の低減が図れる。また、可動部材が倒れる際には、緩衝材２２がストッパー部１２０と裏蓋３に接触しているので、この摩擦抵抗によっても可動部材収容凹部１１に収容されるときの衝撃音の低減が図れる。
【００８２】
また、可動部材２は、可動部材収容凹部１１内に収容された状態で、緩衝材２２が変形してストッパー部１２０と接触しているので、この状態でのがたつきが少ない。
【００８３】
ストッパー部１２０が、基部材１の上面から可動部材収容凹部１１側にやや張り出して、可動部材２の上方に形成してあるので、可動部材２は、起き上がると基部側の上面がストッパー部１２０に当たる。また、下部も裏蓋３の上面に当たる。そして、これらが協働することで可動部材２は鋭角の所要の角度で止められる（図７参照）。
【００８４】
このように可動部材２は、起き上がりが所要の角度で止められるので、立ったままの状態が維持される角度まで回動しない。従って、可動部材２は、起き上がらせていた力がなくなれば、自重で下降して可動部材収容凹部１１内に収容される。このように可動部材２は、床面６から突出した状態を維持できないので、踏んでも怪我をせず安全である。
【００８５】
なお、図７で示す可動部材２は、略４０度の角度で傾斜した状態で、基部側の上面がストッパー部１２０に当たっている。しかし、ストッパー部１２０の形状や停止する可動部材２の角度は、これに限定するものではない。
【００８６】
ところで近年では、室内空気を循環させて室内環境の向上を図るといった観点から、床面との間の隙間が大きく形成される扉が設置される場合もある。そのため、このような扉にも対応できる床面用部材が求められている。
【００８７】
可動部材２は、基部材１の直径よりもやや短い長さを有するので、可動部材２の起き上がり幅を従来のものより大きくできる。これにより床面用部材Ｋは、床面との間の隙間が大きく形成される扉にも対応可能である。なお、可動部材２の長さを長くすれば、大きな隙間が形成される扉にも対応可能であるが、強度的な観点から可動部材２の長さは、基端から先端までが３０〜１００ｍｍ内に設定されるのが望ましい。
【００８８】
可動部材２は、板状体をプレスにより打ち抜いて、その際に打ち込み側の緑部の角が丸く形成されているので、この部分の角に別途丸みを形成する工程は不要である。従って、その分製作時間の短縮が図れる。また、打ち込み側とは反対の側も角を丸くする必要があるが、可動部材２がプレスにより打ち抜いてあることにより、バリを取る加工を施すことで角を丸くすることができる。バリ取りは作業が簡単なバレル加工で対応できる。つまり、可動部材２の角に丸みを形成するのは簡単である。なお、角が丸く形成されていなければ、角が基部材１に当たって起き上がらないことがあるので、角はやや丸く形成されてる方が好ましい。
【００８９】
本実施の形態で扉用部材Ｔ１は、昇降部２１の先端が緩衝材４６に係合したときに、昇降部２１と磁着面４２とが略同じ傾斜角度を有する高さ位置に設置したが、扉用部材Ｔ１の設置位置は、特に限定するものではない。例えば、本実施の形態で示す位置よりも高い位置にも設置できるし、低い位置にも設置できる。
【００９０】
図１１は扉用部材Ｔ１が本実施の形態で示す位置よりも高い位置に設置してある状態を示す部分断面説明図である。
図１１に示す位置に扉用部材Ｔ１が設置されている場合では、起き上がった昇降部２１は、先端が緩衝板４７に当たって磁着面４２に磁着される。この場合、昇降部２１の先端は、緩衝板４７に溝部４７０が設けてあることにより、溝部４７０を形成する２箇所の角部に当たる（図示省略）。そして、昇降部２１は、扉７が開かれるにつれて、先端と溝部４７０の角部が擦れ合いながら（角部はやや変形しながら）僅かに上昇する。このとき溝部４７０がなければ、上昇した昇降部２１は、先端の中央部分が緩衝板４７に当たって食い込むことがあり、この状態で扉が開けられれば、昇降部２１の先端が緩衝板４７を押しやって剥がしてしまうことがある。
【００９１】
図１２は、裏蓋３と裏蓋３の上面に設けられた緩衝材２２ａを示している。この緩衝材２２ａは、変形性を有しており、裏蓋３ａを取り付ける際に基部材１の裏面側から可動部材挿入口１２に挿入することで設けられる。この緩衝材２２ａは、可動部材２が可動部材収容凹部１１に収容された状態で、基部側と裏蓋３の間に挟まれて変形するので、この緩衝材２２ａによって可動部材２が倒れて基部材１と当たったときの振動を抑えることができ、衝撃音の低減が図れる。また、緩衝材２２ａが可動部材２に当たって変形していることによって、可動部材２は摩擦抵抗が加わった状態で倒れるので、これによっても可動部材収容凹部１１に収容されるときの衝撃音の低減が図れる。
【００９２】
図１３は本発明に係る戸当り装置の第２の実施の形態を示す使用状態説明図、図１４は図１３に示す戸当り装置により扉を停止させている状態を示す側面視説明図である。
なお、図１３及び図１４において、上記図１ないし図１１で示したものと同一または同等箇所には同一の符号を付して示している。また、以下の説明において構造について上記で示した箇所と重複する説明は省略する。
【００９３】
戸当り装置は、床面用部材Ｋと、扉７の下部側の側面に外方に突出させて取り付けられる扉用部材Ｔ２とを備えている。
【００９４】
扉用部材Ｔ２は、側面視において外形が略長方形状に形成してある基部材取着台部５０と、基部材取着台部５０の表面から外方に突出させてある基部材当接台部５１を備えている。基部材取着台部５０と基部材当接台部５１は、一体に形成してある。基部材取着台部５０と基部材当接台部５１の内部には、基部材取着台部５０の扉７と当接する面から凹ませて肉抜部５０１が形成してある（図１３参照）。
【００９５】
基部材取着台部５０には、表面から裏面に貫通しており、上方から下方に延びる貫通長穴５００，５００が所要間隔を設けて両側の２箇所に形成してある。各貫通長穴５００の表側の内縁にはざぐりが設けてある。貫通長穴５００，５００には、扉用部材Ｔ２を扉に固定するための木ネジＮ２が通して設けてある（図１３参照）。
【００９６】
基部材当接台部５１の裏側には、磁着面４２と停止面４３が形成してある（図１４参照）。また、基部材当接台部５１には、略円形状を有する磁石収容凹部４４が、磁着面４２の表面より内方に凹ませて形成してあり、更に、基部材当接台部５１の内部には、磁石収容凹部４４の表面より凹ませて肉抜部５１０が形成してある（図１４参照）。上記した肉抜部５０１及び肉抜部５１０は、材料の低減と、軽量化のために形成してある。
【００９７】
扉用部材Ｔ２は、扉７の下部側の側面に、木ネジＮ２，Ｎ２を貫通長穴５００，５００に挿通させてねじ込んで、外方に突出し、かつ、基部材取着台部５０の下部が扉７の下端面と略面一になるようにして取り付けてある。本実施の形態で扉用部材Ｔ２は、基部材取着台部５０の下部が扉７の下端面と略面一になるようにして設置したが、扉用部材Ｔ２の取り付け状態はこれに限定せず、機能上支障がなければ、扉７の下端面より突出させても設置できるし、下端面より上方に位置させても設置できる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a member for a floor surface of a door stop device and a door stop device. More specifically, when installing a member for a floor surface, the floor surface member can be installed without forming a fitting recess. Further, the present invention relates to a structure that can reduce the sound generated by the movement of the movable member of the floor member and also can reduce the impact when the movable member stops the door.
[0002]
[Prior art]
When a door is provided, a door stop device is usually installed on the floor near the wall so that the door does not collide with the wall when the door is opened so that the door is not damaged.
[0003]
As such a door stop device, for example, a device disclosed in JP-A-11-287062 is known (see FIGS. 15 and 16).
This door stop device includes a floor member 8 that is installed on the floor surface and a door member 9 that is used by being attached to the lower side of the door, and the movable member 80 of the floor member 8 includes a door. The door is stopped at a predetermined position by being raised by the magnetic force of the magnet 90 provided in the member 9 and engaging with the stop surface 91.
[0004]
[Problems to be solved by the invention]
The door stop device described above is required to be further improved in the following points.
(1) Since the floor surface member 8 is formed by bending the base side of the movable member 80 into a crank shape, a convex portion for accommodating the shaft portion 800 of the movable member 80 on the back surface of the floor surface member 8. 81 is formed. For this reason, when the floor member 8 is installed, it is necessary to form the fitting concave portion 85 in which the convex portion 81 is embedded in the floor surface by cutting the floor surface. If the fitting recess 85 is formed at an incorrect position, the repair can only be made by replacing the floorboard at that portion with a new one.
Moreover, since the fitting recessed part is formed in a floor surface, the quickness of construction was also lacking.
[0005]
(2) When the movable member 80 is instantly raised by the magnet 90 and hits the door member 9, an impact sound is generated, and a countermeasure for reducing this sound has been demanded.
Further, when the door is stopped, the movable member 80 and the stop surface 91 are in direct contact with each other, and a considerable impact is applied to the floor member 8 and the door member 9, so this mitigation measure is also required. It was. At this time, an impact sound was generated, and a measure for reducing this sound was also sought.
Furthermore, even when the movable member 80 falls from the state where it is raised, the movable member 80 hits the floor member 8 and an impact sound is generated, and a countermeasure for reducing this noise has been demanded.
[0006]
By the way, the present inventor has conducted an experiment for deriving a thickness with practically no hindrance with respect to the thickness of the floor member formed as a convex on the floor surface. And, by repeating the experiment, for those having a floor surface thickness exceeding 5 mm, for example, it was found that it was difficult to climb the wheel of a wheelchair, or it was easy to whip when walking , Proved impractical.
[0007]
The objective of this invention is providing the member for floor surfaces of a door stop apparatus and the door stop apparatus which enable it to install, without forming a fitting recessed part in a floor surface.
Another object of the present invention is to provide a door stop device for reducing the impact sound generated when the movable member hits the door member or floor member, or for reducing the impact when the door is stopped. An object of the present invention is to provide a floor member and a door stop device.
Furthermore, another object of the present invention is to provide a floor member for a door-to-door device in which, for example, it is difficult for a wheelchair wheel to get on or a wheelchair is difficult to ride when walking. And providing a door to door device.

The term “the installation surface on the floor is a flat surface” is used as a concept that includes the case where the installation surface is a flat surface, or strictly speaking, even if it is not a flat surface, it can be handled as a flat surface when installed. is doing.
[0021]
The term “plate-like movable member” is used as a concept including the case where the movable member is plate-like, and strictly speaking, the case where the movable member is not plate-like or handled as plate-like does not cause any problem.
[0022]
The term “the upper surface of the base member and the upper surface of the movable member are flush” is treated as if the upper surface of the base member and the upper surface of the movable member are flush or even if not exactly flush. However, it is used as a concept that includes cases where there is no problem.
[0023]
The term “the movable member and the base member abut” is used as a concept including a case where the movable member and the base member directly abut each other and a case where the movable member and the base member abut each other indirectly.
[0024]
Examples of the nonmagnetic material for forming the base member include zinc, brass, aluminum, magnesium, titanium, stainless steel, synthetic resin, ceramics, and materials formed using these. These surfaces can also be coated with plating, painting, or synthetic resin.
[0025]
(Work)
The floor member of the door stop device and the door stop device operate as follows.
The door member is installed on the lower side of the door using a fixing means or the like. The floor member is placed on the floor surface on the track of the door member, and is installed using a fixing means or the like as it is.
[0026]
When the door is opened and moved to the position where the floor member is installed, the movable member instantly rises due to the magnetic force, engages with the stopping means, and the door stops.
[0027]
When the door is closed, the movable member comes off from the stopping means and falls down, and is accommodated in the movable member accommodating recess. At that time, although an impact sound is generated, the impact sound can be reduced in the floor member provided with the impact sound reduction means.
[0028]
For example, the floor member whose base member has a thickness of 5 mm or less does not become difficult to ride on the wheel of a wheelchair and does not easily roll when walking.
[0029]
The floor member formed by punching the plate-like body of the movable member does not require a step of separately rounding the corner, and the production time can be shortened accordingly.
[0030]
Since the floor member having the rising angle limiting means of the movable member does not rotate to an angle that maintains the upright state of the movable member, the movable member falls down by its own weight and accommodates the movable member when the force raised up is lost. Housed in the recess.
[0031]
In the floor member in which the base member is formed of a nonmagnetic material, the base member is not magnetized and the action of the standing means is not hindered.
[0032]
In the door stop device provided with the impact sound reduction means, the impact sound when the movable member rises instantaneously and hits the door member is reduced.
[0033]
In the door stop device provided with the peeling preventing means, even if the movable member moves against the impact sound reducing means, the impact sound reducing means is not peeled off.
[0034]
In the door stop device provided with the impact mitigating means, when the door is stopped, the impact mitigating means is deformed to mitigate the impact. In addition, the impact noise is reduced by reducing the impact.

The door stop device includes a floor member K installed on the surface of the floor surface 6 and a door member T1 attached to the lower end surface of the door 7. In FIG. 1, the door 7 is indicated by an imaginary line for convenience of explaining the door member T <b> 1.
[0036]
The floor member K includes a thin plate-like base member 1 whose outer shape is formed in a substantially circular shape in plan view. The outer periphery green on the upper side of the base member 1 is chamfered over the entire periphery. Further, the base member 1 is formed with two through holes 10 and 10 penetrating from the upper surface to the rear surface at a required interval. A counterbore is provided at the inner edge of each through hole 10. The through holes 10 and 10 are provided with wood screws N1 for fixing the floor member K to the floor surface 6 (see FIGS. 1, 2 and 3). In the present embodiment, the base member 1 is formed to a thickness of about 3.5 mm, but the thickness of the base member is not limited to this, and is preferably 5 mm or less for the reason described above.
[0037]
In the substantially central portion of the base member 1, a movable member accommodating recess 11 is formed by slightly denting a part of the upper surface. A thin plate-like movable member 2 is accommodated in the movable member accommodating recess 11. The movable member 2 will be described later.
[0038]
The movable member accommodating recess 11 has a substantially rectangular shape formed in a curved shape in which one short side forms an arc in a plan view. The movable member accommodating recess 11 has a required width and is formed to have a length slightly shorter than the diameter of the base member 1. In the present embodiment, the diameter (back surface) of the base member 1 is set to about 70 mm. The movable member housing recess 11 is set to have a width of approximately 21.4 mm and a length of approximately 60.2 mm (center portion). However, the size of the base member 1 and the movable member accommodating recess 11 is not limited to this and can be set as appropriate.
[0039]
The shape of the base member 1 is not limited to a substantially circular shape in a plan view, and for example, a shape having a substantially elliptical shape, a substantially triangular shape, a substantially square shape, a substantially rectangular shape, a substantially polygonal shape or the like in a plan view can be used. . Moreover, the shape of the movable member accommodating recess 11 is not limited to a substantially rectangular shape, and for example, a shape having a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially square shape, a substantially polygonal shape, or the like in plan view is used. it can.
[0040]
The bottom of the movable member accommodating recess 11 is formed in a flat shape. On the bottom of the movable member housing recess 11, the back surface of the movable member 2 when lying down is placed. The movable member accommodating recess 11 is slightly deeper than the thickness of the movable member 2 and has a depth at which the upper surface of the accommodated movable member 2 is slightly recessed from the upper surface of the base member 1. However, this dent width is very small. Therefore, even if the upper surface of the movable member 2 and the upper surface of the base member 1 are handled as the same surface, there is no problem.
[0041]
A rectangular movable member insertion port 12 penetrating the back surface is formed at the bottom of the movable member housing recess 11 on the base side.
[0042]
The back surface of the base member 1 is an installation surface to the floor surface 6, and is formed in a substantially flat shape. On both sides of the short side of the movable member insertion port 12 on the back surface, shaft portion housing recesses 13 and 13 for housing the shaft portions 20 and 20 formed on the movable member 2 are recessed from the back surface to move the movable member insertion port. 12 is formed so as to be continuous with 12.
[0043]
The outer end sides of the shaft-receiving recesses 13 and 13 are formed in a semicircular shape when viewed from the bottom, and cracks and the like are generated due to concentration of stress due to impact when the movable member 2 stops the door 7. It has become difficult. (For example, in the case where the outer end side is formed in a shape having a corner portion, the stress due to the impact is concentrated on the corner portion, so that cracks and cracks may be generated from here).
[0044]
Further, a stopper portion 120 having an inclined surface is formed above the movable member insertion port 12 and the shaft portion accommodating recesses 13 and 13 so as to slightly protrude from the upper surface of the base member 1 to the movable member accommodating recess 11 side ( (See FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9). The stopper unit 120 constitutes an upright angle limiting unit that stops the rising of the movable member 2 at an acute required angle.
[0045]
On the back side, a back cover housing recess 14 for fitting the back cover 3 is formed around the movable member insertion opening 12 and the shaft housing recesses 13, 13 with the back surface slightly recessed. The back cover housing recess 14 has a depth at which the bottom surface of the back cover 3 is slightly recessed from the back surface of the base member 1 when the back cover 3 is fitted.
[0046]
In the back cover housing recess 14, engagement protrusions 15 for attaching the fitted back cover 3 are formed at three locations. Each engagement convex part 15 has a height that protrudes slightly from the back surface of the base member 1, and is formed so as to have a tapered taper on the peripheral surface (see FIG. 9).
[0047]
The base member 1 shown in the present embodiment is a cast product formed by pouring a zinc alloy, which is a nonmagnetic material, into a mold. However, the material forming the base member is not limited to this. For example, a magnetic material such as iron or copper (including a metal whose surface is coated with plating, painting, or synthetic resin) is used. It can also be used. However, it is preferably made of a nonmagnetic material. Moreover, the manufacturing method of a base member is not limited to casting, For example, it can form also by press work, shaving, etc.
[0048]
The movable member 2 includes an elevating part 21 and shaft parts 20 and 20 that are the center of rotation of the elevating part 21. The elevating part 21 has one short side having substantially the same curvature as a curved line forming an arc formed in the movable member accommodating recess 11 in plan view so that the elevator 21 is accommodated in the movable member accommodating recess 11 with substantially no gap. It is formed in a substantially rectangular shape. The shaft parts 20, 20 are formed on both side parts of the base end part of the elevating part 21 so as to protrude laterally.
[0049]
The movable member 2 is formed by punching an iron plate-like body, which is a magnetic material having a thickness of about 1.6 mm, with a press. As a result, the movable member 2 has a flat plate shape, and the shaft portions 20 and 20 and the elevating portion 21 are integrated. Moreover, the movable member 2 is formed by rounding the corners of the green portion on the driving side by punching. The green part on the side opposite to the driving side is deburred and the corners are slightly rounded in the same manner as the driving side. Since the corners on the base side are formed in a round shape in this way, the corners do not stop when they hit the base member 1.
[0050]
In the present embodiment, deburring is performed by barrel processing in which a container containing the punched movable member 2 is rotated or vibrated to finish the surface. However, the deburring method is not limited to this. As described above, the green part of the movable member 2 has rounded corners. However, since the rounding method is based on the above method, the green part is not formed in an arc shape, and the flat part is still between the corners. It remains (see FIG. 6 and FIG. 7). However, the shape of the green part is not limited to this, and can be formed in an arc shape.
[0051]
In FIG. 4, a cushioning material 22 made of a polyethylene tubular body having cushioning properties and stretchability is provided on the shaft portion 20 of the movable member 2 on the lower side so as to cover the peripheral surface portion. The buffer material 22 is provided so as to form a thin film on the shaft portion 20 over the entire circumference of the shaft portion 20 in an extended state (see FIGS. 4, 6, and 7). The shock absorbing material 22 constitutes an impact sound reducing means for reducing the impact sound when the movable member in the raised state falls down and hits the base member.
[0052]
The movable member 2 is inserted into the movable member insertion port 12 from the back side of the base member 1, and the shaft portions 20, 20 are inserted into the shaft portion receiving recesses 13, 13 so that the base end portion is located below the stopper portion 120. It is assembled integrally with the base member 1 by accommodating the elevating part 21 in the movable member accommodating recess 11 with almost no gap. In the state in which the movable member 2 is housed in the movable member housing recess 11, the upper portion of the cushioning material 22 is deformed and is in contact with the stopper portion 120, and the lower portion of the cushioning material 22 is in contact with the upper surface of the back cover ( (See FIG. 6).
[0053]
In the present embodiment, the movable member 2 is set to have a width of approximately 21 mm and a length of approximately 59.8 mm. However, the size of the movable member 2 is not limited to this, and can be set as appropriate depending on the size of the movable member housing recess 11.
The movable member 2 shown in the present embodiment is formed by punching a plate-like body, but the method for forming the movable member is not limited to this. The movable member can also be manufactured by casting or shaving.
[0054]
In this embodiment, the movable member 2 is an iron plate, and the surface is plated to prevent rust and improve the appearance. However, the movable member is not particularly limited as long as it can be magnetically attached to the magnet 45 as described later. The movable member may be formed so as to include a metal that can be magnetized.
[0055]
Further, the cushioning material is not limited to the one shown in the present embodiment, and if the impact sound when the movable member 2 falls and hits the base member 1 can be reduced, the material to be formed, the shape, the location to be provided, and the location to be provided The method is not particularly limited. As a material for forming the buffer material, for example, other synthetic resins (for example, (foamed polyurethane resin)), rubber, paint, oil (including grease), non-woven fabric, cork, and the like can be used. For example, it can also be provided in a location as shown in FIG. In addition, what is shown in FIG. 12 is mentioned later. Furthermore, the buffer material can be provided by adhesion, fitting, adhesion (application, dipping), adhesion, or the like.
[0056]
In the present embodiment, the cushioning material 22 is provided only on one of the predetermined shaft portions 20, but may be provided on both shaft portions 20, 20. The reason why the side of the shaft portion 20 on which the cushioning material 22 is provided is predetermined in order to facilitate maintenance management.
[0057]
The back cover 3 is attached to the back cover housing recess 14. An engagement hole 30 is formed in the back cover 3 at a location corresponding to the engagement protrusion 15. The back cover 3 is formed by punching a metal plate-like body. However, the back cover 3 can also be manufactured by casting or shaving.
[0058]
The back cover 3 fits each engagement hole 30 to the corresponding engagement convex portion 15 and fits into the back cover accommodating concave portion 14, and the tip of the engagement convex portion 15 protruding through the engagement hole 30 with a hammer or the like It is attached so that it does not come off from the back cover housing recess 14 by crushing and expanding the diameter. The movable member insertion port 12 and the shaft portion receiving recesses 13 and 13 are closed by attaching the back cover 3 to the back cover receiving recess 14 and cannot be seen from the outside.
[0059]
The door member T1 includes a base member 4 whose outer shape is formed in a substantially oval shape in plan view. The substantially semicircular portions on both sides of the base member 4 are formed with a small diameter except for the lower green portion. Further, flange portions 40, 40 projecting outward are formed on the lower edge portions of both sides of the base member 4.
[0060]
In the base member 4, through holes 41, 41 penetrating from the upper surface to the back surface are formed at two positions with a required interval. A counterbore is provided on the lower inner edge of each through hole 41. The through holes 41, 41 are provided with wood screws N2 for fixing the door member T1 to the door (see FIG. 1).
[0061]
On the back side of the base member 4, there are formed a magnetic attachment surface 42 on which the elevating part 21 is magnetically attached when the movable member 2 is raised, and a stop surface 43 as stop means (FIGS. 2, 3, and 10). reference). Both the magnetized surface 42 and the stop surface 43 are inclined. The lower side of the magnetized surface 42 expands in the lateral direction, and is formed so that the raised and lowered portion 21 that is raised easily adheres to the magnetized surface 42 (see FIG. 10).
[0062]
Further, the base member 4 is formed with a substantially circular magnet housing recess 44 that is recessed inward from the surface of the magnetized surface 42. A magnet 45 serving as a standing means is accommodated in the magnet accommodating recess 44. The magnet 45 is accommodated such that the lower surface thereof is substantially flush with the surface of the magnetized surface 42.
[0063]
The stop surface 43 is provided with a cushioning material 46 that is an impact reducing means. The buffer material 46 is made of rubber having a required thickness and having a flat surface, and is attached with an adhesive. In addition, the surface of the buffer material 46 can also be formed in uneven | corrugated shape or a waveform, for example.
[0064]
Further, a buffer plate 47 which is an impact sound reducing means for reducing sound is provided on the surface of the magnetic attachment surface 42. The buffer plate 47 uses a thin rubber plate and is attached with an adhesive. The buffer plate 47 has a groove portion 470 formed at a location extending over the entire width of the magnetic attachment surface 42 in the central portion. (See FIG. 10).
[0065]
The base member 4 shown in the present embodiment is a cast product formed by pouring a zinc alloy, which is a nonmagnetic material, into a mold. However, the material forming the base member is not limited to this. For example, a metal such as iron (including a material whose surface is coated with plating, painting, or synthetic resin) is used. You can also. Moreover, the manufacturing method of a base member is not limited to casting, For example, it can form also by press work, shaving, etc.
[0066]
In the present embodiment, the magnet 45 is provided so that the lower surface is substantially flush with the surface of the magnetized surface 42, but the attachment state of the magnet 45 is not limited. The magnet should just raise the raising / lowering part 21 and raise it. Therefore, if this function can be satisfied, for example, a required member can be interposed between the magnet and the elevating part 21, or can be provided by being recessed from the magnetized surface 42, or a convex part can be formed. It can also be provided. Usually, a permanent magnet is used as the magnet 45, but this is not limited, and for example, an electromagnet can also be used.
[0067]
In the present embodiment, the cushioning material 46 and the cushioning plate 47 are made of rubber, but the material to be formed and the method of providing are not particularly limited. As a material, for example, other synthetic resins (for example, (foamed polyurethane resin), etc.), paints, nonwoven fabrics, corks and the like having various buffering properties can be used. Moreover, it can also provide by fitting, adhesion | attachment (application | coating, dipping), sticking, etc. Further, the buffer plate may be provided at a required position of the movable member 2 that rises up and contacts the door member T1, for example.
[0068]
(Work)
The operation of the first embodiment of the present invention will be described with reference to FIGS.
The door member T1 and the floor member K are installed on the door 7 and the floor surface 6, respectively.
The door member T1 is fitted into a recess formed in advance on the lower end surface of the door 7, and screwed by inserting the wood screws N2, N2 through the through holes 41, 41. In the door member T <b> 1, when the tip of the elevating part 21 is engaged with the buffer material 46, the elevating part 21 and the magnetic attachment surface 42 have substantially the same inclination angle, and the upper surface of the elevating part 21 is the magnetic attachment surface 42. It is installed at a height position where it is magnetically attached to.
[0069]
Further, in the present embodiment, the door member T1 is installed so that the flange portions 40, 40 are hooked on the lower end surface so as to protrude from the lower end surface by the thickness of the flange portions 40, 40. However, the attachment of the door member T1 is not limited to this, and it can be installed so as to be flush with the lower end surface of the door 7 if there is no functional problem, or it is installed recessed from the lower end surface. You can also.
[0070]
Since the floor member K is formed in the shape of the movable member 2 in a flat plate shape with the shaft portions 20 and 20 projecting to the side on the base side, the convexity as formed on the back surface of the conventional floor member is provided. The portion can be eliminated and the back surface can be formed in a substantially flat shape.
Further, since the movable member 2 is formed in a flat plate shape, the thickness of the base member 1 that accommodates the movable member 2 can be reduced. As a result, the portion provided on the floor surface 6 when installed is not as thin as a conventional floor surface member, but can be thinned to a practically satisfactory level.
[0071]
Accordingly, the floor member K determines the installation position on the floor surface 6 on the track of the door member T1, inserts the wood screws N1 and N1 into the through holes 10 and 10 and screws them into the floor surface 6, The upper surface of the member K is attached so as to be substantially flush with the surface of the floor surface 6.
[0072]
In this way, the floor member K can be installed on the floor 6 without forming a fitting recess as conventionally formed. For this reason, even if installed in the wrong position, it can be easily installed again without replacing the floorboard with a new one. In addition, the installation is simple, so the construction is also quick.
[0073]
When the door 7 is opened to the position where the floor member K is installed, the elevating part 21 is attracted by the magnetic force of the magnet 45 and instantly rises around the shaft parts 20 and 20.
[0074]
The rising and lowering unit 21 that has risen is magnetically attached to the magnetic attachment surface 42 with the upper surface on the front side being in contact with the lower side of the buffer plate 47. Since the elevating part 21 gets up and hits the buffer plate 47, the impact sound when it hits the magnetized surface 42 can be reduced.
[0075]
And as the door 7 is opened, the elevating part 21 slightly rises while the upper surface rubs against the lower side of the buffer plate 47 (see FIG. 2). The tip of the elevating part 21 does not hit the buffer plate 47 until it hits the buffer material 46.
[0076]
The tip of the elevating part 21 that has risen as the door 7 is opened hits the buffer material 46 and engages. As a result, the door 7 stops moving and stops. The elevating part 21 is inclined at substantially the same inclination angle as the magnetized surface 42 by engaging the cushioning material 46 at the tip, and the upper surface abuts on the surface of the buffer plate 47 and is magnetized on the magnetized surface 42 (see FIG. 3). .
[0077]
Since the door 7 is stopped by engaging the tip of the elevating part 21 with the cushioning material 46 in this way, the impact applied to the movable member 2 and the door member T1 when the door 7 is stopped can be reduced. The life of the door-to-door device can be extended. Moreover, the impact noise can be reduced by reducing the impact.
[0078]
Note that the movable member 2 shown in FIG. 3 is inclined at an angle of approximately 19 degrees from the floor surface. However, the angle at which the movable member 2 contacts the cushioning material 46 is not limited to this, and varies depending on the vertical distance between the floor member K and the door member T1.
[0079]
The movable member 2 magnetically attached to the magnetic attachment surface 42 is maintained in this state by a magnetic force. Thereby, the state where the door 7 is also stopped at a predetermined position is maintained.
[0080]
In order to release the stopped state of the door 7, the door 7 may be moved in the closing direction. By moving the door 7 in the closing direction, the lower side of the magnetized surface 42 pushes down the elevating part 21, thereby releasing the magnetized state. The movable member 2 falls and is accommodated in the movable member accommodating recess 11.
[0081]
When the movable member 2 falls and is accommodated in the movable member accommodating recess 11, the cushioning material 22 comes into contact with the stopper portion 120 and the back cover 3 and is deformed. The vibration at the time of hitting is suppressed, and the impact sound can be reduced. Further, when the movable member falls down, the shock absorbing material 22 is in contact with the stopper portion 120 and the back cover 3, so that the impact sound when being accommodated in the movable member accommodating recess 11 can also be reduced by this frictional resistance. .
[0082]
Moreover, since the shock absorbing material 22 deform | transforms and the movable member 2 is in the state accommodated in the movable member accommodation recessed part 11, it contacts with the stopper part 120, Therefore Shaking in this state is little.
[0083]
Since the stopper portion 120 slightly protrudes from the upper surface of the base member 1 toward the movable member housing recess 11 and is formed above the movable member 2, the upper surface of the base portion abuts against the stopper portion 120 when the movable member 2 rises. . Further, the lower part also hits the upper surface of the back cover 3. The movable member 2 is stopped at a required acute angle (see FIG. 7).
[0084]
Thus, since the movable member 2 is stopped at a required angle, the movable member 2 does not rotate to an angle that maintains the standing state. Therefore, the movable member 2 descends by its own weight and is accommodated in the movable member accommodating recess 11 when the force that has been raised is lost. Thus, since the movable member 2 cannot maintain the state which protruded from the floor surface 6, even if it steps on, it does not hurt and is safe.
[0085]
Note that the movable member 2 shown in FIG. 7 is inclined at an angle of approximately 40 degrees, and the upper surface on the base side is in contact with the stopper 120. However, the shape of the stopper 120 and the angle of the movable member 2 to stop are not limited to this.
[0086]
By the way, in recent years, from the viewpoint of improving indoor environment by circulating indoor air, a door with a large gap between the floor and the floor may be installed. Therefore, there is a demand for a floor member that can handle such a door.
[0087]
Since the movable member 2 has a length slightly shorter than the diameter of the base member 1, the rising width of the movable member 2 can be made larger than that of the conventional one. Thereby, the member K for floor surfaces can respond also to the door in which the clearance gap between the floor surfaces is formed large. In addition, if the length of the movable member 2 is increased, it can be applied to a door in which a large gap is formed. However, from the viewpoint of strength, the length of the movable member 2 is 30 to 100 mm from the proximal end to the distal end. It is desirable to set within.
[0088]
Since the movable member 2 is formed by punching a plate-like body by pressing and the corners of the green portion on the driving side are rounded at that time, a step of separately rounding the corners of this portion is unnecessary. Therefore, the production time can be shortened accordingly. Further, the side opposite to the driving side needs to have rounded corners. However, since the movable member 2 is punched by a press, the corners can be rounded by performing a burr removal process. Deburring can be done by barrel processing, which is easy to work with. That is, it is easy to form roundness at the corners of the movable member 2. In addition, if the corner is not formed in a round shape, the corner may hit the base member 1 and may not rise, so it is preferable that the corner is formed in a slightly round shape.
[0089]
In the present embodiment, the door member T1 is installed at a height position where the elevating part 21 and the magnetized surface 42 have substantially the same inclination angle when the tip of the elevating part 21 is engaged with the cushioning material 46. The installation position of the door member T1 is not particularly limited. For example, it can be installed at a position higher than the position shown in this embodiment, or can be installed at a lower position.
[0090]
FIG. 11 is a partial cross-sectional explanatory view showing a state in which the door member T1 is installed at a position higher than the position shown in the present embodiment.
When the door member T <b> 1 is installed at the position shown in FIG. 11, the rising / lowering portion 21 that has risen is magnetically attached to the magnetic attachment surface 42 with the tip abutting against the buffer plate 47. In this case, the tip of the elevating part 21 hits two corners forming the groove part 470 (not shown) because the buffer part 47 is provided with the groove part 470. Then, as the door 7 is opened, the elevating part 21 slightly rises while the tip and the corner of the groove 470 rub against each other (the corner is slightly deformed). At this time, if the groove 470 is not present, the lifted lift 21 may bite when the central portion of the tip hits the buffer plate 47. If the door is opened in this state, the tip of the lift 21 pushes the buffer plate 47. May peel off.

FIG. 12 shows the back cover 3 and the cushioning material 22 a provided on the top surface of the back cover 3. This buffer material 22a has a deformability and is provided by being inserted into the movable member insertion port 12 from the back surface side of the base member 1 when the back cover 3a is attached. Since the buffer member 22a is deformed by being sandwiched between the base side and the back cover 3 in a state in which the movable member 2 is housed in the movable member housing recess 11, the movable member 2 is tilted by the buffer material 22a and the base member is collapsed. The vibration when hitting the member 1 can be suppressed, and the impact sound can be reduced. In addition, since the shock absorbing material 22a hits the movable member 2 and is deformed, the movable member 2 falls down in a state where frictional resistance is applied. This also reduces the impact sound when being accommodated in the movable member accommodating recess 11. I can plan.

【The invention's effect】
The present invention has the above-described configuration and has the following effects.
(A) The floor member according to the present invention can be installed on the floor without forming a fitting recess as conventionally formed. For this reason, even if installed in the wrong position, it can be easily installed again without replacing the floorboard with a new one. Also, the installation can be done quickly because it is easy to install.
[0100]
(B) The floor member provided with impact sound reduction means for reducing the impact sound when the movable member falls down and hits the base member is closed when the movable member falls down and hits the base member by closing the door The impact sound can be reduced.
Moreover, the door stop device provided with the impact sound reduction means for reducing the impact sound when the movable member gets up and hits the door member has an impact sound when the movable member rises instantaneously and hits the door member. Can be reduced. Thus, the thing provided with the said means can aim at reduction of an impact sound, and can reduce a noise.
[0101]
(C) The floor member whose thickness of the base member is set to 5 mm or less, for example, does not make it difficult for the wheel of a wheelchair to climb up by the floor member installed on the floor surface. It won't be easy to fire.
[0102]
(D) The floor member in which the movable member is formed by punching the plate-like body does not require a step of forming a rounded corner, and the production time can be shortened accordingly.
[0103]
(E) The floor member having the standing angle limiting means can stop the movable member that rises at a required acute angle so that it does not rise above the angle. Therefore, the movable member does not rotate to an angle that maintains the standing state. For this reason, when the force that has been raised is lost, the movable member falls by its own weight and is accommodated in the movable member accommodating recess. Thus, since the member for floor surfaces cannot maintain the state which the movable member protruded from the floor surface, even if it steps on, it is safe without being injured.
[0104]
(F) In the floor member in which the base member is formed of a nonmagnetic material, the base member is not magnetized, and the movable member is not magnetically attached to the base member. Thereby, the action by the standing means is not hindered.
[0105]
(G) In the door stop device provided with the peeling prevention means, even when the door is moved in a state where the movable member hits the impact sound reducing means, the impact sound reducing means is not peeled off by the movable member.
[0106]
(H) In the door stop device provided with the impact mitigating means, the impact mitigating means is deformed when the door is stopped, and the impact applied to the movable member and the door member is mitigated. Thereby, the lifetime of a door stop apparatus can be extended. Further, the impact sound is reduced by reducing the impact.
