Description

【０００１】
【発明の属する技術分野】
この発明は、扉開閉用の蝶番を扉枠に対して安定よく取付ける補強具に関するものである。
【０００２】
【従来の技術】
一般に、扉を開閉自在に支持する蝶番は２枚の取付片を有し、その一方は扉にねじ止めされ、他方は扉枠の竪枠にねじ止めされる。
【０００３】
ここで、扉枠は、金属板をプレス成形したものであるため、薄肉厚であり、上記竪枠にねじ孔を直接形成すると、ねじ山数が不足して蝶番取付け用のビスを強く締付けることができず、取付片を強固に固定することができない。
【０００４】
このため、竪枠の蝶番取付部の背面側に厚みのある補強板を取付け、その補強板に形成されたねじ孔にビスをねじ係合して、取付片の取付けの安定化を図るようにしている。
【０００５】
【発明が解決しようとする課題】
ところで、従来から知られている蝶番取付け用の補強板は、扉枠の竪枠に溶接止めによる手段を介して固着されるため、図８（Ｉ）に示すように、扉枠２０に蝶番６を介して扉２２を開閉自在に支持した状態において、地震により、図８（ＩＩ）に示すように、扉枠２０が菱形に変形すると、扉２２の戸先き側の端部が扉枠２０の下枠２４、あるいは上枠２５に衝撃的に当接して変形することがある。その変形量が多い場合、扉２２を開放させることができず、避難できない場合があり、安全性を確保するうえにおいて、改善すべき点がある。
【０００６】
この発明の課題は、地震等によって扉枠が変形しても、扉が変形するのを防止することができるようにした扉用蝶番取付け用の補強具を提供することである。
【０００７】
【課題を解決するための手段】
上記の課題を解決するために、第１の発明においては、扉枠の蝶番取付部の背面側に固着される補強板と、その補強板に衝合された摺動板と、この摺動板を補強板に押圧する弾性部材とから成り、上記補強板には蝶番の取付片に形成されたねじ挿入孔と対向する位置に上下方向に長い長孔を設け、上記摺動板には上記長孔と対向する位置に蝶番取付片の取付け用ねじがねじ係合されるねじ孔を形成した構成を採用している。
【０００８】
ここで、弾性部材として皿ばねを用いることができる。
【０００９】
上記の構成から成る補強具は、扉枠における竪枠の背面側に補強板を固着し、蝶番の一方の取付片に形成されたねじ挿入孔から補強板の長孔に挿入されたビスを摺動板に設けられたねじ孔にねじ係合し、そのビスの締付けにより上記取付片を固定する。また、蝶番の他方の取付片を扉の吊元側の端面にねじ止めして扉を開閉自在に支持し、扉の戸先き側端部に上向き又は下向きに衝撃力が加わった場合に、補強板と摺動板との間に滑りを生じさせて上記衝撃力を吸収し、扉の変形を防止する。
【００１０】
また、第２の発明においては、扉枠の蝶番取付部の背面側に固着される補強板と、その補強板の背面側に取付けられたカバーと、そのカバー内に組込まれて上下方向に移動自在に支持された摺動板とから成り、上記補強板には蝶番の取付片に形成されたねじ挿入孔と対向する位置に上下方向に長い長孔を設け、上記摺動板には上記長孔と対向する位置に蝶番取付片の取付け用ねじがねじ係合されるねじ孔を形成し、上記摺動板の上下方向への移動時に弾性変形し、その復元弾性によって摺動板を初期の組立て位置に復帰させる弾性体を摺動板とカバーとの間に組込んだ構成を採用している。
【００１１】
ここで、弾性体としてスプリングを採用することができる。この弾性体の組込みに際して、摺動板の両側に切欠部を形成し、その切欠部に上記弾性体を組込み、その弾性体の上下端部をカバーに形成された上下一対の突出部で受けるようにしている。
【００１２】
上記の構成から成る補強具は、扉用蝶番の一方の取付片を摺動板にねじ込まれるビスの締付けにより固定し、扉に上方向又は下方向の衝撃力が作用した場合、摺動板の上下方向の移動によってその衝撃力を吸収する。また、衝撃力が解除されると、弾性体の復元弾性によって扉を元の状態に復帰させる。
【００１３】
【発明の実施の形態】
以下、この発明の実施の形態を図１乃至図７に基づいて説明する。
【００１４】
図１乃至図３に示すように、この発明に係る補強具は、扉枠の竪枠に取付けられる補強板１と、その補強板１の背面側に衝合される摺動板２と、その摺動板２を覆う箱形のカバー３を有する。
【００１５】
図３に示すように、補強板１には、上下端部にビス孔４が形成され、その上下のビス孔４間に上下方向に長い複数の長孔５が設けられている。長孔５の配列は、図４に示す蝶番６の取付片７に形成された複数の挿入孔８と同じ配列とされている。また、補強板１には取付け時の位置決め用の突部９が設けられている。
【００１６】
摺動板２には、上記ビス孔４と対向する位置に上下方向に長い長孔１０が形成されている。また、摺動板２には補強板１の長孔５と対向する位置にねじ孔１１が形成されている。ねじ孔１１は前記蝶番６の取付片７に設けられた複数のねじ挿入孔８と同位置に設けられている。
【００１７】
前記カバー３には補強板１のビス孔４と対向する位置にナット１２が固着され、上記ビス孔４から摺動板２の長孔１０に挿入されるビス１３が上記ナット１２にねじ係合されている。
【００１８】
ビス１３には、摺動板２とカバー３との間にワッシャ１４と皿ばね１５とが嵌合されている。皿ばね１５はビス１３の締付けによって変形し、その復元弾性により摺動板２を補強板１に押圧している。
【００１９】
実施の形態で示す補強具は上記の構造から成り、図４はその使用状態を示し、補強板１は扉枠における竪枠２１における蝶番取付部の背面に溶接による手段を介して固着されている。
【００２０】
蝶番６における２枚の取付片の一方は扉２２の吊元側端面にねじ止めされ、他方の取付片７は、その取付片７に形成された複数のねじ挿入孔８から補強板１の長孔５に挿入されて摺動板２のねじ孔１１にねじ込まれるビス１６の締付けによって竪枠２１に取付けられている。
【００２１】
ここで、竪枠２１にはビス１６が挿入される位置に、そのビス１６の上下方向の移動を許容する透孔２３が設けられている。
【００２２】
上記のような扉２２の支持状態において、地震等により扉枠が菱形に変形して、扉２２の戸先き側端部が扉枠の上枠又は下枠に衝撃的に当接すると、補強板１と摺動板２との間で滑りが生じ、扉２２は押圧された方向に移動し、その移動によって扉２２の変形が防止される。
【００２３】
このため、扉２２が開放することができないという不都合の発生を防止し、安全性の確保が図られる。
【００２４】
実施の形態のように、ビス１３の締付けによって摺動板２の背面側にカバー３を取付けることにより、そのカバー３によって摺動板２を覆うことができるため、扉枠の竪枠２１内にコンクリート打ち込む扉枠の固定時に、そのコンクリートが摺動板２の移動を阻害する部分に進入するのを防止することができ、摺動板２としての機能を充分に発揮させることができる。
【００２５】
また、ビス１３を弛めることにより、皿ばね１５の弾性力を弱めることができるため、扉２２の高さを任意に調整することができる。
【００２６】
図５乃至図７は、この発明に係る補強具の他の実施の形態を示す。この実施の形態に示す補強具は、図１乃至図３に示す補強具のワッシャ１４および皿ばね１５を省略して、摺動板２を上下方向に移動自在に支持し、上記摺動板２の両側部に一対の切欠部３０を設け、各切欠部３０にスプリングから成る弾性体３１を組込み、一方、カバー３には各弾性体３１の上下端部を受ける上下一対の突出部３２を形成している。また、摺動板２を移動自在に支持するため、ビス１３にカラー３３を嵌合し、そのカラー３３によって補強板１とナット１２間に摺動板２を移動可能とする間隔を保持している。
【００２７】
他の構成は、図１乃至図３に示す補強具と同一であるため、同一部品に同一符号を付して説明する。また、補強具の取付けおよび蝶番の取付けも前記と同様であるため、説明を省略する。
【００２８】
上記補強具の使用状態において、扉枠の変形により扉に衝撃力が加わると、摺動板２が衝撃力の加わる方向に移動して、その衝撃力を吸収する。このため、扉が変形するのが防止される。
【００２９】
ここで、摺動板２が移動すると、弾性体３１が弾性変形し、扉に加わる衝撃力が解除されると、その弾性体３１の復元弾性によって摺動板２および扉が元の状態に戻されることにより、扉を元の状態に戻す復帰作業を省略することができる。
【００３０】
【発明の効果】
以上のように、この発明においては、扉枠の変形によって扉の戸先き側に上方向又は下方向の衝撃力を受けると、その衝撃力を受ける方向に摺動板が移動して上記衝撃力を吸収するため、扉が変形するのを防止することができ、安全性の向上を図ることができる。
