Description

【0001】
【発明の属する技術分野】
本発明は、戸の閉止の際に戸板に制動力を付与する制動装置に係る技術分野に属する。
【0002】
【従来の技術】
従来、戸の制動装置としては、例えば、特開平9−72154号公報に記載のものが知られている。
【0003】
この従来の戸の制動装置は、戸枠等に取付けられる溝型のレールと、レールの溝の内部に突出して取付けられる傾斜山形の制動板と、戸板に取付けられレールに沿って走行する走行機構と、戸板に取付けられ制動板との当接で弾圧変位してレールまたは走行車輪に摩擦接触することにより戸板に制動力を付与する制動駆動機構とを備えてなる。
【0004】
【発明が解決しようとする課題】
前述の従来の戸の制動装置では、戸板に付与される制動力を調整しようとすると、制動板,制動駆動機構の全部または一部の部材交換が必要になるため、制動力の調整作業が面倒であるという問題点がある。
【0005】
本発明は、このような問題点を考慮してなされたもので、戸板に付与される制動力を簡単に調整することのできる戸の制動装置を提供することを課題とする。
【0006】
【課題を解決するための手段】
前述の課題を解決するため、本発明に係る戸の制動装置は、次のような手段を採用する。
【0007】
即ち、請求項1では、戸枠等に取付けられる溝型のレールと、レールの溝の内部に突出して取付けられ一端部に傾斜面を有する制動板と、戸板に取付けられレールに沿って走行する走行機構と、戸板に取付けられ制動板との当接で戸板に制動力を付与する制動駆動機構とを備えてなる戸の制動装置において、制動板にレールの溝の内部での突出量を調整する突出量調整機構を設け、突出量調整機構は、制動板の他端部に被さるように制動板のネジ挿通孔を通るネジで戸枠等に固定されるコ字形のベースと、ベースの皿孔に挿通されるとともに制動板に螺合されて先端部が座金を介してカシメられる調整ネジと、ベース,制動板の間に介装されるバネ材とからなり、前記制動板の他端部は、調整ネジの回転動作に応じてベースに接近離間することを特徴とする。
【0008】
この手段では、突出量調整機構の調整ネジの回転操作により制動板のレールの溝の内部での突出量を調整されると、制動駆動機構の制動駆動量が可変され、部材交換等を行わずに戸板に付与される制動力を調整することができる。
また、制動板の他端部のベースへの接近 , 離間がバネ材の弾圧に抗したり弾圧に沿って行われるため、接近 , 離間が助勢されて操作性が良好である。
【0017】
【発明の実施の形態】
以下、本発明に係る戸の制動装置の実施の形態を図面に基づいて説明する。
【0018】
この実施の形態は、引戸からなる戸板Aを下荷重式で支える戸車装置からなる走行機構1に実現されたものを示してある。
【0019】
この実施の形態の走行機構1は、戸板Aの木口面(側端面)Aa,下端面Abに掘込まれた取付溝Acに埋込み取付けされるもので、外装が下部開放のブロック形に形成され戸板Aに取付ネジで締付け固定されるケーシング11からなる。ケーシング11の内部には、戸板Aの前後方向(厚み方向)に中心軸12が配設されている。中心軸12は、ケーシング11の内部で戸板Aの前後方向にのみスライド可能な第1ホルダ13と、ケーシング11の内部で戸板Aの前後方向へのスライドと回転とが可能な第2ホルダ14とをそれぞれ挿通組付けしている。第1ホルダ13は、ケーシング11の側面に臨んだ前後調整ネジ15の回転操作により、偏心突起16を介して、戸板Aの前後方向にスライド変位される(図6参照)。第2ホルダ14は、ケーシング11の側面に臨んだ上下調整ネジ17の回転操作により、スライダ18を介して、戸板Aの上下方向に回転変位される(図5参照)。なお、第2ホルダ14は、コ字形に形成された本体部14aの内部に戸板Aの前後方向に回転軸14bが配設されて走行車輪19を回転可能に支持している。また、この第2ホルダ14の本体部14aの内側面には、後述の制動駆動機構2の下方へのスライド域を規制する突起14cが設けられている。
【0020】
この走行機構1では、前後調整ネジ15,上下調整ネジ17の回転操作により、戸板Aの支持位置を上下前後に調整できることになる。
【0021】
この走行機構1には、制動駆動機構2が一体的に組込まれている。制動駆動機構2は、走行機構1の中心軸12に挿通組付けされケーシング11(第1ホルダ13,第2ホルダ14)の内部で戸板Aの前後方向,上下方向へのスライドとが可能な本体部21と、本体部21の戸板Aの上下方向へのスライドを可能にする長孔22と、本体部21を下方へ弾圧するコイルスプリング23と、本体部21の下部に円弧形に形成されケーシング11から走行車輪19よりも下方へ突出して後述のレール3を走行する走行部24と、本体部21に取付けられ走行車輪19に接触するゴム等の摩擦材25と、本体部32から第2ホルダ14の突起14c近くにまで円弧形に延びたストッパ片26とからなる。
【0022】
この制動駆動機構2では、下方へのスライドで摩擦材25と走行機構1の走行車輪19との接触が解除され、上方へのスライドで摩擦材25と走行機構1の走行車輪19とが接触することになる。また、走行機構1の前後調整ネジ15,上下調整ネジ17の回転操作による戸板Aの支持位置の調整に対して、一体的に変位することになる。そして、戸板Aの上下方向への支持位置の調整の際には、図5,図6に示すように、全体が下方へスライドして、走行機構1の走行車輪19の突出量aの変化にかかわらず走行車輪19からの走行部24の突出量bが変動しないようになっている。
【0023】
走行機構1の走行車輪19と制動駆動機構2の走行部24とが走行するレール3は、断面がほぼコ字形の溝形に形成され戸枠Bに埋込み固定される。
【0024】
レール3の溝の内部には、断面がほぼコ字形の制動板4が伏せられて溝の内部に突出するような格好で取付けられている。従って、走行機構1の走行車輪19よりも下方へ突出してレール3を走行する制動駆動機構2の走行部24は、制動板4への当接で上方へスライドすることになる。この制動板4には、一端部に傾斜面41が形成され、他端部に座付ネジ孔42,ネジ挿通孔43,小突起44が設けられている。
【0025】
制動板4には、制動板4の突出量を調整する突出量調整機構5が連結されている。この突出量調整機構5は、戸枠Bに制動板4に被されるように制動板4のネジ挿通孔43を通るネジ51で固定されるベース52と、ベース52に挿通され制動板4の座付ネジ孔42に螺合され座金53を介して先端部がカシメられる調整ネジ54と、ベース52と制動板4の小突起44と間に介装されるバネ材55とからなる。なお、ベース52は、コ字形の本体部52aにネジ51,調整ネジ54を受ける皿孔52b,52cと制動板4の小突起44の対になる小突起52dとが設けられている。
【0026】
この実施の形態によると、突出量調整機構5の調整ネジ54を回転操作すると、制動板4の他端部がベース52に接近,離間することになる。この結果、制動駆動機構2の走行部24と制動板4との間隔が接近,離間して、制動駆動機構2の上方へのスライド量が変更されることになる。即ち、制動駆動機構2の摩擦材25と走行機構1の走行車輪19との接触圧力が可変され、戸板Aに付与される制動力が調整されることになる。
【0027】
この突出量調整機構5による戸板Aに付与される制動力の調整が調整ネジ54を回転操作で行われるため、調整作業が容易である。また、制動板4の他端部のベース52へ接近,離間がバネ材55の弾圧に抗したり弾圧に沿って行われるため、接近,離間が助勢されて操作性が良好である。
【0028】
さらに、この実施の形態によると、突出量調整機構5の構造が簡素であるため、安価,容易に製造することができる。また、突出量調整機構5がレール3の配設に影響なく設備されるため、既存のレールについて追加実施することも可能である。
【0029】
なお、戸板Aに付与される制動力を適正に維持すると、制動板4,制動駆動機構2の無用な摩耗損傷を防止することができるため、長期に有効に制動機能を発揮することができることになる。
【0030】
以上、図示した実施の形態の外に、上荷重式,吊戸式等他の開閉構造のものについても適用することができる。
【0031】
【発明の効果】
以上のように、本発明に係る戸の制動装置は、突出量調整機構により制動板のレールの溝の内部での突出量を調整して、制動駆動機構の制動駆動量を可変すると、部材交換等を行わずに戸板に付与される制動力を調整することができるため、戸板に付与される制動力を簡単に調整することができる効果がある。
【0032】
さらに、戸板に付与される制動力を簡単に調整することができることから、制動力を適正に維持して制動板,制動駆動機構の無用な摩耗損傷を防止することができるため、長期に有効に制動機能を発揮することができる効果がある。
