本発明者は、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに、開信号を受けて扉を自動的に開け、これによって扉が扉枠に嵌ったまま開かなくなる扉枠の開口の閉塞を回避し、扉枠の開口部としての機能を維持して緊急避難路が無くなるという問題を解決することを考えた。しかし、そうした場合、外力が強いときは、むしろ扉を開けることが扉枠及びその周辺の構造の強度を低下させることにつながり、扉構造周辺の構造物が崩壊して被害が甚大となる。   In the event of an earthquake or other disaster where an external force acts on the door structure, or when this disaster is expected, the inventor automatically opens the door in response to an open signal, so that the door remains fitted in the door frame. We thought to solve the problem that the emergency evacuation route disappears by maintaining the function as the opening of the door frame by avoiding the blockage of the opening of the door frame that does not open. However, in such a case, when the external force is strong, rather, opening the door leads to lowering the strength of the door frame and the surrounding structure, and the structure around the door structure collapses, causing serious damage.

また、本発明者は、例えば地下室のように容易に水が流入し得るような場所に扉があり、水害等で扉の外側の水位が上がってくると、扉の外側と内側の水圧差で扉が開かなくなり、室外への脱出が困難になる。そのため、こういった事態が予想されるか、あるいは水位が上がり始めた初期の段階で開信号を受けて扉を自動的に開け、これによっていよいよ水位が上がり、パワーアシストを得るにしても抵抗の増大により扉が開かなくなることを回避し、室内に水を導入して扉の外側と内側の水位差をほぼ無くしておき、脱出時に扉を人力で開くことができるようにすることを考えた。しかし、そうした場合、急激に水位が上がってくるなかで水の静圧、動圧を受けつつこれに抗して扉を開けるときに扉を開けるための機構が大きな負荷を受けて損傷を受け、扉が閉まるという事態が予想され、これでは所期の目的を達成できない。また、扉を開けてから水が流入してきたときでも、水流によって開いた扉が大きな力を受け、扉を開けるための機構が大きな負荷を受けて損傷を受け、扉が閉まるという事態も予想される。   In addition, the inventor has a door in a place where water can easily flow in, for example, in a basement, and when the water level on the outside of the door rises due to water damage or the like, the water pressure difference between the outside and inside of the door The door will not open, making it difficult to escape outside. Therefore, when such a situation is anticipated or when the water level begins to rise, the door is automatically opened in response to an opening signal, which eventually raises the water level, and even if power assistance is obtained We thought that the door could not be opened due to the increase, water was introduced into the room, and the difference in water level between the outside and inside of the door was almost eliminated, and the door could be opened manually when escaping. However, in such a case, when the door is opened against the static pressure and dynamic pressure of water while the water level suddenly rises, the mechanism for opening the door is damaged due to a heavy load, It is expected that the door will close, and this will not achieve the intended purpose. Also, even when water flows in after the door is opened, it is expected that the door opened by the water flow will receive a large force, the mechanism for opening the door will be damaged due to a heavy load, and the door will close. The

また、扉のノブ、ハンドル等の操作が困難である身障者等が容易に扉を開け閉めできるようにするために特許文献２のような装置を設けた場合、扉が弾性部材で開放方向に弾力的に付勢されているので、開いた扉が、敏捷な動作によって咄嗟に避けることが困難な身障者等に衝突することがあり、これでは安心して装置を使用することができない。このような問題は、扉が引いて開かれる引き扉構造であっても扉が押して開かれる押し扉構造であっても、扉の開く側に身障者等が居るときには起こりうる。その場合、扉から一定範囲に人が居ることをセンサー等で検出し、そのときは扉が開かないように制御することが考えられる。しかし、引き扉構造でそうしたときは、操作者が扉から充分に離れて押しボタンを操作しなければならない煩わしさがあるし、押し扉構造でそうしたときは、扉の向こうの様子が分からない操作者が扉が開かない理由を理解できず、不安になる。   In addition, when a device such as Patent Document 2 is provided so that a disabled person or the like who is difficult to operate a door knob, handle, etc. can open and close the door, the door is elastic and elastic in the opening direction. Therefore, the open door may collide with a handicapped person who is difficult to avoid by agile movement, and the device cannot be used with confidence. Such a problem may occur when there is a handicapped person or the like on the side where the door is opened, regardless of whether the door is pulled and opened or the door is pushed and opened. In that case, it can be considered that a sensor or the like detects that there is a person within a certain range from the door, and at that time, the door is not opened. However, when doing so with the sliding door structure, there is an annoyance that the operator must operate the push button sufficiently away from the door, and when doing so with the push door structure, the operation beyond the door is unknown. Can't understand why the door doesn't open, and they become anxious.

本発明は、このような点に着目してなされたもので、その目的とするところは、扉を開けるときは、扉の回動側端部と扉枠との間に隙間があく程度まで開けるに留め、これによって次のことを実現することにある。第１に、例えば地震のような災害のとき又はこの災害が予想されるときに開信号を受けて扉を自動的に開ける用途においては、隙間に指、手又はバールその他のこじ開け用工具を入れて扉をこじ開けることを可能にし、扉枠の開口の閉塞を回避して緊急避難路を確保できるようにしながら、扉によって扉枠及びその周辺の構造の強度を支えて扉構造周辺の構造物の崩壊を防止する。第２に、例えば水害のような災害のとき又はこの災害が予想されるときに開信号を受けて水が流入するような場所の扉を自動的に開ける用途においては、水の静圧、動圧を受けつつ確実に扉を開けて室内に水を導入して扉の外側と内側の水位差をほぼ無くし、脱出時に扉を人力で開くことができるようにする。第３に、身障者等の操作で扉を開ける用途においては身障者等への扉の不用意な衝突を回避し、安心して扉を開けることができ、また扉に近づいて押しボタン等により扉を開ける操作ができ、隙間から扉の向こうの様子を確認して扉を全開することの可否を判断でき、隙間等を手がかりに扉を全開することができるようにする。   The present invention has been made paying attention to such points. The purpose of the present invention is to open a door to the extent that there is a gap between the end of the door on the rotating side and the door frame. This is to realize the following. First, in an application that automatically opens the door in response to an open signal in the event of a disaster such as an earthquake, or when this disaster is anticipated, insert a finger, hand or bar or other pry tool in the gap. The door can be opened open, and the door frame opening can be avoided and an emergency evacuation path can be secured, while the door supports the strength of the door frame and its surrounding structure, Prevent collapse. Secondly, in the event of a disaster such as a flood or when this disaster is anticipated, an application that automatically opens the door of a place where water flows in response to an open signal, The door is surely opened while receiving pressure, and water is introduced into the room to substantially eliminate the difference in water level between the outside and inside of the door, so that the door can be opened manually when evacuating. Thirdly, in applications where the door is opened by the handicapped, etc., it is possible to avoid inadvertent collision of the door with the handicapped person, so that the door can be opened with peace of mind, and the door can be opened with a push button or the like when approaching the door. It is possible to operate, confirm the situation beyond the door through the gap, determine whether the door can be fully opened, and allow the door to be fully opened using the gap or the like as a clue.

さらに、上記従来の装置では、バネの復原力を利用して扉を開くようにしているが、災害時又は災害予想時から平常時に戻ったときに開いた扉を押して閉めることを可能とするために、バネの復原力は人力で押し返せる程度のものに設定せざるを得ない。そのため、地震等の災害時には開いた扉に、扉の開いた側から扉に何かが倒れかかってきて開いた扉を閉める外力が作用した場合、バネの復原力が外力に負けて扉が閉まり、そのために扉を押し開けて室外に脱出することができなくなるという問題が起こる。また、水害等の災害時には水圧により、開いた扉を閉める外力が作用した場合、同様にバネの復原力が外力に負けて扉が閉まり、そのために扉を押し開けて室外に脱出することができなくなるという問題が起こる。   Furthermore, in the above-mentioned conventional apparatus, the door is opened using the restoring force of the spring, but it is possible to push and close the opened door when returning to normal time from a disaster or when a disaster is predicted. In addition, the restoring force of the spring must be set to a level that can be pushed back by human power. Therefore, when an external force is applied to a door that has opened due to an earthquake or other disaster, and the door opens from the side where the door opens and closes the door, the restoring force of the spring loses the external force and the door closes. Therefore, there arises a problem that the door cannot be pushed open to escape from the room. Also, in the event of a disaster such as flooding, if an external force that closes the open door is applied due to water pressure, the spring's restoring force will be defeated by the external force and the door will close, so that the door can be pushed open to escape to the outside. The problem of disappearing occurs.

そこで、本発明では、開いた扉が外力を受けても閉まらないようにして、災害時に脱出不能になることを防ぐことも目的としている。   Therefore, an object of the present invention is to prevent the opened door from being closed even if it receives an external force so that it cannot be escaped during a disaster.

上記目的を達成する解決手段としての本発明の扉構造の扉開放装置は、扉枠と、この扉枠を開け閉めし、閉じたときに扉枠に嵌るようにほぼ上下に延びる軸のまわりに回動可能に設けられた扉と、扉を閉じ状態に保持する保持装置とを備えた扉構造に設けられる扉開放装置である。そして、この扉開放装置は、扉の閉じ状態への保持を解除する解除装置と、扉を、開方向への拘束なく開く開装置と、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から出力される開信号を受けると、扉の閉じ状態への保持を解除して扉を開くように解除装置及び開装置を制御する災害用開制御装置とを備え、扉の開き角度が、扉の回動側端部と扉枠との間に指、手又はバールその他のこじ開け用工具が差し込まれる隙間ができる程度の開き角度となるように構成している。   The door opening device of the door structure of the present invention as a solution to achieve the above object includes a door frame and an axis extending substantially up and down so as to open and close the door frame and fit the door frame when closed. It is a door opening device provided in the door structure provided with the door provided so that rotation was possible, and the holding device holding a door in a closed state. The door opening device includes a release device that releases the door from being held in a closed state, an opening device that opens the door without restraining in the opening direction, and an earthquake or other disaster in which an external force acts on the door structure. When an open signal output from an open signal output device provided separately when this disaster is expected is received, a disaster that controls the release device and the opening device to release the holding of the door to the closed state and open the door The opening angle of the door is such that there is a gap in which a finger, hand or bar or other prying tool is inserted between the rotation end of the door and the door frame. It is configured as follows.

この扉構造の扉開放装置においては、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から開信号が出力されると、災害用開制御装置が開信号を受け、解除装置及び開装置が制御され、扉の閉じ状態への保持を解除し、扉が扉の回動側端部と扉枠との間に隙間があく程度まで開く。そのため、隙間に指、手又はバールその他のこじ開け用工具を差し込めば扉をこじ開けることが可能になり、扉枠の開口の閉塞を回避して緊急避難路を確保でき、しかも扉における扉枠に嵌る部分を或る程度残すことで扉によって扉枠及びその周辺の構造の強度が支えられて扉構造周辺の構造物の崩壊が防止される。   In the door opening device of this door structure, when an open signal is output from an open signal output device provided separately during an earthquake or other disaster where external force acts on the door structure or when this disaster is expected, The opening control device receives the opening signal, the release device and the opening device are controlled, the door is released from being held in the closed state, and the door has a clearance between the rotation end of the door and the door frame. open. Therefore, it is possible to open the door by inserting a finger, hand or bar or other prying tool into the gap, avoiding blockage of the door frame opening and securing an emergency evacuation path, and fitting into the door frame in the door By leaving the part to some extent, the door supports the strength of the door frame and the surrounding structure, and prevents the structure around the door structure from collapsing.

本発明の別の扉構造の扉開放装置は、扉枠と、この扉枠を開け閉めし、閉じたときに扉枠に嵌るようにほぼ上下に延びる軸のまわりに回動可能に設けられた扉と、扉を閉じ状態に保持する保持装置とを備えた扉構造に設けられる扉開放装置である。そして、この扉開放装置は、扉の閉じ状態への保持を解除する解除装置と、扉を、開方向への拘束なく開く開装置と、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から出力される開信号を受けると、扉の閉じ状態への保持を解除して扉を開くように解除装置及び開装置を制御する災害用開制御装置とを備え、扉の開き角度が、扉の回動側端部と扉枠との間に、扉の内側へ水を導入できる隙間ができる程度の開き角度となるように構成している。   The door opening device of another door structure according to the present invention is provided so as to be rotatable about a door frame and an axis extending substantially vertically so as to fit the door frame when the door frame is opened and closed. It is a door opening device provided in a door structure including a door and a holding device that holds the door in a closed state. And this door opening device is a release device that releases the door to the closed state, an opening device that opens the door without restraining in the opening direction, and other disasters where water flows into the outside of the door frame. When an open signal is output from an open signal output device provided separately or when this disaster is anticipated, the release device and the open device are controlled so that the door is released and the door is opened. The opening angle of the door is such that there is a gap that allows water to be introduced into the inside of the door between the rotation side end of the door and the door frame. It is composed.

この扉構造の扉開放装置においては、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から開信号が出力されると、災害用開制御装置が開信号を受け、解除装置及び開装置が制御され、扉の閉じ状態への保持を解除し、扉が扉の回動側端部と扉枠との間に隙間があく程度まで開く。そのため、隙間から扉の内側へ水が導入され、扉の外側と内側の水位差がほぼ無くなり、脱出時に扉を人力で開くことができるようになる。また、隙間が最小限に抑えられるため、急激に水位が上がってくるなかで水の静圧、動圧を受けつつこれに抗して扉を開けるときでも、扉を開けるための開装置が大きな負荷を受けることが防止され、損傷を受けたり、それによって不意に扉が閉まるという事態が回避される。しかも、隙間が最小限に抑えられることで、扉を開けてから水が流入してきたときでも、水流によって開いた扉が大きな力を受けにくく、扉を開けるための開装置が大きな負荷を受けることが防止され、損傷を受けたり、それによって不意に扉が閉まるという事態が回避される。   In the door opening device of this door structure, when an open signal is output from an open signal output device provided separately in the event of a flood or other disaster where water flows into the outside of the door frame or when this disaster is expected, The open control device for disaster receives the open signal, the release device and the open device are controlled, the door is released from the closed state, and the door has a gap between the end of the door and the door frame. Open to the extent. Therefore, water is introduced into the door from the gap, and the difference in water level between the outside and the inside of the door is almost eliminated, and the door can be opened manually when escaping. In addition, since the gap is minimized, the opening device for opening the door is large even when the door is opened against the static and dynamic pressure of water while the water level suddenly rises. It is prevented from receiving a load, and the situation where the door is closed due to damage or unexpectedly is avoided. Moreover, since the gap is kept to a minimum, even when water flows in after the door is opened, the door that is opened by the water flow is not easily subjected to a large force, and the opening device for opening the door is subjected to a large load. Is prevented, and the situation where the door is closed unexpectedly due to damage is avoided.

本発明の扉構造の扉開放装置は、開いた扉が閉じる方向へ外力を受けても扉が閉じないように構成してもよい。   The door opening device of the door structure of the present invention may be configured such that the door does not close even when an external force is applied in the closing direction.

このようにすれば、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに、開いた扉に、扉の開いた側から扉に何かが倒れかかってきて開いた扉を閉める外力が作用しても、このような力によって扉が閉じることがないので、本装置本来の脱出手段確保の機能が維持される。また、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに、開いた扉に、扉の開いた側から水圧がかかってきて開いた扉を閉める外力が作用しても、このような力によって扉が閉じることがないので、本装置本来の水導入の機能が維持される。   In this way, in the event of an earthquake or other disaster where an external force acts on the door structure, or when this disaster is expected, something will fall on the door from the door opening side and open. Even if an external force that closes the door is applied, the door is not closed by such a force, so that the original function of securing the escape means is maintained. Also, in the event of a flood or other disaster where water flows into the outside of the door frame or when this disaster is anticipated, external force is applied to the open door to apply water pressure from the door opening side to close the open door. Even if it acts, the door is not closed by such force, so that the original water introduction function of the present apparatus is maintained.

本発明の扉構造の扉開放装置は、開装置が、扉枠その他、扉の周辺に設けられた本体と、この本体に、基端がほぼ上下に延びる回動軸のまわりに回動可能に設けられ、先端で扉を押し又は引くアームと、本体に設けられ、アームを回動させる駆動装置とを備えており、この駆動装置が、アームの上記回動軸に設けられたギヤ又はアームの上記回動軸に連動するギヤと、このギヤの中心軸と交差し且つ上記ギヤと噛み合うウォームが設けられた出力軸を有してこれを回転駆動する回転駆動装置とを備えるようにしてもよい。   In the door opening device of the door structure of the present invention, the opening device can be rotated around a door frame and other main body provided around the door, and a rotation shaft extending substantially vertically at the base end of the main body. An arm that pushes or pulls the door at the tip, and a drive device that is provided on the main body and rotates the arm, and this drive device is provided with a gear or an arm provided on the rotation shaft of the arm. There may be provided a gear interlocking with the rotation shaft, and a rotation drive device having an output shaft provided with a worm that intersects with the central axis of the gear and meshes with the gear and rotationally drives the output shaft. .

このようにすれば、回転駆動装置が出力軸を回転駆動すると、回転力がウォームからギヤに伝わり、さらに回動軸に伝わってアームを回動させ、アームの先端が扉を押し又は引いてこれを開く。その場合、アームの先端と扉とは何ら連結関係を持たないことから、開装置は扉に対して開方向への拘束を行わず、扉がアームから離れてそれ以上開くことが可能である。そして、開いた扉が閉じる方向へ外力を受けても、ギヤの回転力はギヤの回動軸と交差する回動軸を持つウォームによって受け止められるので、アームは回動せず、扉は閉じない。   In this way, when the rotation drive device drives the output shaft to rotate, the rotational force is transmitted from the worm to the gear, and further, the arm is rotated by the rotation shaft, and the tip of the arm pushes or pulls the door. open. In that case, since the tip of the arm and the door do not have any connection relationship, the opening device does not restrain the door in the opening direction, and the door can be opened further away from the arm. And even if the open door receives an external force in the closing direction, the rotational force of the gear is received by a worm having a rotating shaft that intersects the rotating shaft of the gear, so the arm does not rotate and the door does not close. .

本発明の別の扉構造の扉開放装置は、扉枠と、この扉枠を開け閉めし、閉じたときに扉枠に嵌るようにほぼ上下に延びる軸のまわりに回動可能に設けられた扉と、扉を閉じ状態に保持する保持装置とを備えた扉構造に設けられる扉開放装置であって、扉の閉じ状態への保持を解除する解除装置と、扉を、開方向への拘束なく開く開装置と、操作を受けると、扉の閉じ状態への保持を解除して扉を開くように解除装置及び開装置を制御する操作時開制御装置とを備え、扉の開き角度が、扉の回動側端部と扉枠との間に隙間ができる程度の開き角度となるように構成している。   The door opening device of another door structure according to the present invention is provided so as to be rotatable about a door frame and an axis extending substantially vertically so as to fit the door frame when the door frame is opened and closed. A door opening device provided in a door structure including a door and a holding device that holds the door in a closed state, and a release device that releases the door from being closed, and the door is restrained in the opening direction. And an opening control device for controlling the release device and the opening device so as to open the door by releasing the holding of the door to the closed state when the operation is received, and the opening angle of the door is The opening angle is such that a gap is formed between the end of the door on the rotating side and the door frame.

この扉構造の扉開放装置においては、身障者等が操作時開制御装置を操作すると、解除装置及び開装置が制御され、扉の閉じ状態への保持を解除し、扉が扉の回動側端部と扉枠との間に隙間があく程度まで開く。そのため、身障者等への扉の不用意な衝突が回避され、扉に近づいて押しボタン等の操作装置により扉を開ける操作ができ、隙間から扉の向こうの様子を確認でき、隙間に手その他の身体部位又は杖その他の器具を差し込んで引き、扉の回動側端部付近を手がかりに手、肩、脚その他の身体部位又は杖その他の器具を当てるなどして引き、又は扉を押すことで扉を全開にすることができる。   In the door opening device of this door structure, when a disabled person or the like operates the opening control device during operation, the release device and the opening device are controlled to release the door from being held in the closed state, and the door is turned to the rotation end of the door. Open to the extent that there is a gap between the part and the door frame. Therefore, inadvertent collision of the door with people with disabilities, etc. can be avoided, the door can be opened with an operation device such as a push button approaching the door, the state of the door beyond the gap can be confirmed, By inserting and pulling a body part or cane or other device, pulling by pushing the door by hitting the hand, shoulder, leg or other body part or cane or other device using the vicinity of the rotation side end of the door as a clue The door can be fully opened.

本発明の扉構造の扉開放装置は、さらに、扉を閉じる方向へ付勢する閉装置が設けられており、開装置は閉装置の閉じ力に抗して扉を開けるように構成されていてもよい。   The door opening device of the door structure of the present invention is further provided with a closing device that biases the door in the closing direction, and the opening device is configured to open the door against the closing force of the closing device. Also good.

このようにすれば、災害用開制御装置又は操作時開制御装置による上記制御が解除されたときに、閉装置によって扉が閉じられる。   If it does in this way, when the said control by the opening control apparatus for disasters or the opening control apparatus at the time of operation is cancelled | released, a door will be closed by a closing device.

本発明の扉構造の扉開放装置は、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに扉が、扉の回動側端部と扉枠との間に隙間があく程度まで開くので、隙間に指、手又はバールその他のこじ開け用工具を差し込んで扉をこじ開けることを可能にし、扉枠の開口の閉塞を回避して緊急避難路を確保できるようにしながら、扉における扉枠に嵌る部分を或る程度残すことで扉によって扉枠及びその周辺の構造の強度を支えて扉構造周辺の構造物の崩壊を防止することができる。   The door opening device of the door structure of the present invention has a door between the rotation side end of the door and the door frame in the event of an earthquake or other disaster where an external force acts on the door structure or when this disaster is expected. As the gap opens, the door can be opened by inserting a finger, hand or bar or other prying tool into the gap, and the emergency evacuation route can be secured by avoiding the blockage of the door frame opening. By leaving a part of the door that fits in the door frame to some extent, the door can support the strength of the door frame and the surrounding structure and prevent the structure around the door structure from collapsing.

本発明の別の扉構造の扉開放装置は、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに扉が、扉の回動側端部と扉枠との間に隙間があく程度まで開くので、隙間から扉の内側へ水が導入され、扉の外側と内側の水位差がほぼ無くなり、脱出時に扉を人力で開くことができるようになる。また、隙間が最小限に抑えられるため、扉を開けるための開装置が大きな負荷を受けることが防止され、損傷を受けたり、それによって不意に扉が閉まるという事態が回避される。   The door opening device of another door structure according to the present invention is configured such that the door is in contact with the rotation side end of the door and the door frame in the event of a flood or other disaster where water flows into the outside of the door frame or when this disaster is expected. Since the water is introduced to the inside of the door through the gap, the difference in water level between the outside and the inside of the door is almost eliminated, and the door can be opened manually when escaping. In addition, since the gap is minimized, the opening device for opening the door is prevented from receiving a large load, and the situation where the door is damaged or unexpectedly closed is avoided.

また、開いた扉が閉じる方向へ外力を受けても扉が閉じないように構成したときには、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに本装置本来の脱出手段確保の機能が維持され、また、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに本装置本来の水導入の機能が維持される。   In addition, when the door is configured not to close even when an external force is applied in the direction in which the opened door closes, when the earthquake or other disasters in which external force acts on the door structure or when this disaster is expected, The function of securing the escape means is maintained, and the original water introduction function of the apparatus is maintained in the event of a flood or other disaster where water flows outside the door frame or when this disaster is expected.

さらに、開装置をギヤ及びこれに噛み合うウォームを用いて構成したときは、簡単な構造でもって開いた扉が閉じる方向へ外力を受けても扉が閉じないという機能を実現することができる。   Furthermore, when the opening device is configured using a gear and a worm meshing with the gear, it is possible to realize a function that the door does not close even when an external force is applied in the closing direction with a simple structure.

本発明の別の扉構造の扉開放装置は、身障者等の操作により扉が、扉の回動側端部と扉枠との間に隙間があく程度まで開くので、身障者等への扉の不用意な衝突を回避し、安心して扉を開けることができ、また扉に近づいて押しボタン等の操作装置により扉を開ける操作ができ、隙間から扉の向こうの様子を確認して扉を全開することの可否を判断でき、隙間や扉の回動側端部付近を手がかりに扉を引き、又は扉を押すことで扉を全開にすることができる。   The door opening device of another door structure of the present invention opens the door to the extent that there is a gap between the rotation side end of the door and the door frame by the operation of the disabled person. You can avoid prepared collisions and open the door with peace of mind, and you can operate the door close to the door with an operating device such as a push button. Check the state of the door from the gap and fully open the door. The door can be fully opened by pulling the door or pushing the door in the vicinity of the clearance or the rotation side end of the door.

さらに、扉を閉じる方向へ付勢する閉装置が設け、開装置が閉装置の閉じ力に抗して扉を開けるように構成すれば、災害用開制御装置又は操作時開制御装置による上記制御が解除されたときに、閉装置によって扉を閉じることができ、無意味に扉が開き続けることが防止される。   Furthermore, if a closing device for biasing the door in the closing direction is provided and the opening device is configured to open the door against the closing force of the closing device, the above control by the disaster opening control device or the operation opening control device is performed. When is released, the door can be closed by the closing device, and it is prevented that the door keeps opening without meaning.

以下、本発明の扉構造の扉開放装置の実施の形態を説明する。図１ないし図３は、第１実施形態の扉構造の扉開放装置を示す。この扉構造は、扉枠１０と、この扉枠１０を開け閉めする扉２０と、扉２０を閉じ状態に保持する保持装置３０とを備えている。   Hereinafter, embodiments of the door opening device of the door structure of the present invention will be described. FIG. 1 thru | or 3 shows the door opening apparatus of the door structure of 1st Embodiment. The door structure includes a door frame 10, a door 20 that opens and closes the door frame 10, and a holding device 30 that holds the door 20 in a closed state.

扉枠１０は、壁その他の構造物を貫通するように設けられた枠体であって、この扉枠１０の内側の空間により開口部が形成される。図では扉枠１０をほぼ矩形状に形成しているが、これに限定されるものではない。扉２０は、ほぼ上下に延びる軸２１のまわりに回動可能に設けられている。   The door frame 10 is a frame provided so as to penetrate a wall or other structure, and an opening is formed by a space inside the door frame 10. In the figure, the door frame 10 is formed in a substantially rectangular shape, but the present invention is not limited to this. The door 20 is provided so as to be rotatable around a shaft 21 extending substantially vertically.

扉２０は、この扉枠１０を開け閉めし、閉じたときに扉枠１０に嵌るように設けられている。この実施形態の場合、軸２１は蝶番の軸であるが、構造によっては仮想の軸を意味することがある。図では扉枠１０の幅方向の一端に軸２１が設けられているが、扉枠１０における軸の幅方向の位置がこれによって限定されるものではない。扉２０は扉枠１０が設けられた壁その他の構造物を境にして一方側に開くが、この扉２０が開いていく側を扉開き側といい、逆側を扉閉じ側という。   The door 20 is provided so that the door frame 10 is opened and closed, and is fitted to the door frame 10 when the door frame 10 is closed. In this embodiment, the shaft 21 is a hinge shaft, but depending on the structure, it may mean a virtual shaft. In the figure, the shaft 21 is provided at one end of the door frame 10 in the width direction, but the position of the shaft in the width direction of the door frame 10 is not limited thereto. The door 20 opens to one side with a wall or other structure provided with the door frame 10 as a boundary. The side on which the door 20 opens is called the door opening side, and the opposite side is called the door closing side.

保持装置３０は、扉２０が閉じ状態にあるときに扉枠１０及び扉２０に設けられ、一方を他方に係止する装置である。この実施形態の場合、保持装置３０は、例えば図３に示すような扉２０に設けられたラッチ３１と、図４に示すような扉枠１０に設けられた凹部３５とを備えている。ラッチ３１は扉２０の幅方向の両端面のうち回動側の端面からバネ力に付勢されて突出し又は押されると扉２０のなかへ引っ込み且つ扉２０のノブ３２を回動することでバネ力に抗して引っ込むように構成された突起状の部材である。凹部３５は扉が閉じたときに扉２０の上記端面が対向する扉枠１０を凹ませて設けられている。扉２０が閉じるときはラッチ３１が扉枠１０における凹部３５の周囲の部位に押されてバネ力に抗して引っ込んでから元の位置に復原することで凹部３５に嵌り、一方扉２０が閉じたときにノブ３２を回動するとラッチ３１が引っ込んで扉２０の閉じ状態への保持を解除でき、扉２０を開けることが可能となるように構成されている。   The holding device 30 is a device that is provided on the door frame 10 and the door 20 when the door 20 is in the closed state, and locks one of the doors 20 to the other. In the case of this embodiment, the holding device 30 includes, for example, a latch 31 provided in the door 20 as shown in FIG. 3 and a recess 35 provided in the door frame 10 as shown in FIG. The latch 31 protrudes into the door 20 and rotates the knob 32 of the door 20 when it is pushed or pushed by the spring force from the end face on the rotating side of both end faces in the width direction of the door 20 to rotate the knob 32 of the door 20. It is a protruding member configured to retract against a force. The recess 35 is provided by recessing the door frame 10 facing the end face of the door 20 when the door is closed. When the door 20 is closed, the latch 31 is pushed by a portion around the recess 35 in the door frame 10 and retracted against the spring force, and then restored to the original position to fit into the recess 35, while the door 20 is closed. When the knob 32 is rotated, the latch 31 is retracted, so that the door 20 can be released from the closed state, and the door 20 can be opened.

扉構造の扉開放装置は、扉２０の閉じ状態への保持を解除する解除装置１１０と、扉２０を、開方向への拘束なく開く開装置１２０と、解除装置１１０及び開装置１２０を制御する災害用開制御装置１３０とを備えている。   The door structure door opening device controls the release device 110 that releases the door 20 from being held in the closed state, the opening device 120 that opens the door 20 without restriction in the opening direction, and the release device 110 and the opening device 120. And a disaster open control device 130.

解除装置１１０は、保持装置３０が作動しているにもかかわらず、その機能を制限し、扉２０の閉じ状態への保持を解除するものである。この実施形態の場合、保持装置３０の凹部３５を構成する部材に解除装置１１０を設けている。図５に示すように、解除装置１１０は、扉枠１０の内部に、ほぼ上下に延びる軸１１２のまわりに回動可能に設けられた係止部材１１１と、この係止部材１１１を回動させる駆動装置（図示省略）とを備えており、図５に示すように通常は係止部材１１１が凹部３５の扉開き側の壁を構成する状態にあるが、図６に示すように災害用開制御装置１３０又は後述する操作時開制御装置１４０から信号を受けると駆動装置により係止部材１１１が回動して扉枠１０の内方へ逃げることで凹部３５の扉開き側の壁がなくなり、ラッチ３１が扉開き側に開放されて扉開き側へ移動可能になるように構成している。駆動装置に代えて係止部材１１１を拘束するピン等のストッパを設け、通常は係止部材１１１を凹部３５の扉開き側の壁を構成する位置に位置づけておき、ストッパを外すことで係止部材１１１がバネ等の付勢力を受けて扉枠１０の内方へ逃げるようにしてもよい。解除装置は保持装置３０のラッチ３１に関連づけて設けてもよく、例えば災害用開制御装置１３０又は操作時開制御装置１４０から信号を受けるとラッチ３１が扉２０のなかへ引っ込むように構成すればよい。   The releasing device 110 limits the function of the holding device 30 in spite of the operation of the holding device 30 and releases the holding of the door 20 in the closed state. In the case of this embodiment, the release device 110 is provided on the member constituting the recess 35 of the holding device 30. As shown in FIG. 5, the release device 110 is provided inside the door frame 10 so as to be rotatable about a shaft 112 extending substantially vertically, and rotates the locking member 111. As shown in FIG. 5, the locking member 111 normally forms a wall on the door opening side of the recess 35 as shown in FIG. When a signal is received from the control device 130 or the operation opening control device 140 described later, the locking member 111 is rotated by the driving device and escapes inward of the door frame 10, thereby eliminating the wall on the door opening side of the recess 35. The latch 31 is configured to be open to the door opening side and movable to the door opening side. Instead of the driving device, a stopper such as a pin for restraining the locking member 111 is provided. Usually, the locking member 111 is positioned at a position constituting the wall of the recess 35 on the door opening side, and is locked by removing the stopper. The member 111 may receive an urging force such as a spring and escape to the inside of the door frame 10. The release device may be provided in association with the latch 31 of the holding device 30. For example, when receiving a signal from the disaster opening control device 130 or the operation opening control device 140, the latch 31 is retracted into the door 20. Good.

開装置１２０は、扉２０を押し又は引いて開くように構成している。また、開装置１２０は、扉２０を開方向への拘束なく開くように構成している。すなわち、扉２０を開いたときに、扉２０が開装置１２０から離れてそれ以上開くことを可能となるように構成している。この実施形態の場合、図１、図２、図７及び図８に示すように、開装置１２０は、扉閉じ側において扉枠１０その他、扉２０の周辺に設けられた本体１２１と、この本体１２１に、基端がほぼ上下に延びる回動軸１２２ａのまわりに回動可能に設けられ、先端で扉を押すアーム１２２と、本体１２１に設けられ、アーム１２２を回動させる駆動装置１２３とを備えており、アーム１２２が回動するとアーム１２２の先端が扉２０を押してこれを開き、その場合にアーム１２２の先端と扉２０とが何ら連結関係を持たないことから扉２０が開装置１２０のアーム１２２から離れてそれ以上開くことを可能となるようにしている。開装置の変形例としては扉開き側において扉枠その他、扉の周辺に設けられ、アームの先端を扉に引っ掛けて扉を引いて開けるようにしたものがある。他にも開装置としては、伸縮して伸長時に扉を押すプッシュロッドを備えたものや、先端を扉を引っ掛け、収縮時に扉を引く伸縮ロッドを備えたものなどが含まれる。   The opening device 120 is configured to push or pull the door 20 to open. The opening device 120 is configured to open the door 20 without any restriction in the opening direction. That is, when the door 20 is opened, the door 20 can be separated from the opening device 120 and opened further. In this embodiment, as shown in FIGS. 1, 2, 7, and 8, the opening device 120 includes a main body 121 provided around the door frame 10 and the door 20 on the door closing side, and the main body 121. 121 includes an arm 122 that is pivotable about a pivot shaft 122 a whose base end extends substantially vertically, and pushes the door at the tip, and a drive device 123 that is provided on the main body 121 and pivots the arm 122. When the arm 122 rotates, the tip of the arm 122 pushes and opens the door 20, and in this case, the tip of the arm 122 and the door 20 have no connection relationship, so the door 20 is connected to the opening device 120. Further opening away from the arm 122 is possible. As a modification of the opening device, there is a door frame or the like provided around the door on the door opening side so that the end of the arm is hooked on the door and the door is pulled to open. Other opening devices include those equipped with push rods that expand and contract to push the door when extended, and those equipped with a telescopic rod that hooks the door at the tip and pulls the door when contracted.

災害用開制御装置１３０は、電源、電気回路等を備え、解除装置１１０及び開装置１２０に接続され、これらを制御する。この実施形態の場合、災害用開制御装置１３０は開装置１２０の本体１２１に内蔵され、電線等を介して解除装置１１０及び開装置１２０に電気的に接続されている。その接続形態としては電気的な接続、電波通信による接続、光通信による接続その他の形態がある。災害用開制御装置１３０は、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から出力される開信号を受けると、扉２０の閉じ状態への保持を解除して扉２０を開くように解除装置１１０及び開装置１２０を制御するように構成されている。この実施形態の場合、開信号出力装置からの開信号の発信形態は、電波による信号の発信である。従って、災害用開制御装置１３０は、開信号を受信する受信回路を含んでいる。それ以外の開信号の発信形態として、例えば電話線、光ファイバー、専用線等を通じた信号の伝送、インターネットを通じた信号の伝送が例示される。開信号出力装置は扉構造の扉開放装置を設けた家屋等から離れた場所に設けてもよいし、同じ家屋等に設けてもよい。地震その他、扉構造に外力が作用する災害のときとは、地震の場合を例にとると、実際に地震で揺れだした初期の段階を意味しており、これは例えば振動を検出する感振センサの出力信号により検出することができる。地震その他、扉構造に外力が作用する災害が予想されるときとは、なんらかの根拠でこのような災害が予想されるときであり、これには例えば一連の地震における初期微動を受けて本震を予想すること、伝播速度の速いＰ波を検知したときに通常それよりも遅れて届くＳ波の伝播到来を予想すること、動物の異常な反応を受けて地震の発生を予想することなどが含まれる。振動の検出には例えば感振センサが用いられる。   The disaster opening control device 130 includes a power source, an electric circuit, and the like, and is connected to the release device 110 and the opening device 120 to control them. In the case of this embodiment, the disaster opening control device 130 is built in the main body 121 of the opening device 120 and is electrically connected to the releasing device 110 and the opening device 120 via an electric wire or the like. The connection forms include electrical connection, connection by radio wave communication, connection by optical communication, and other forms. The disaster open control device 130 receives the open signal output from the open signal output device provided separately when an earthquake or other disasters in which an external force acts on the door structure or when this disaster is expected, The release device 110 and the opening device 120 are controlled so as to open the door 20 by releasing the holding in the closed state. In the case of this embodiment, the transmission form of the open signal from the open signal output device is transmission of a signal by radio waves. Therefore, the disaster opening control device 130 includes a receiving circuit that receives the opening signal. Other forms of open signal transmission include, for example, signal transmission through a telephone line, an optical fiber, a dedicated line, etc., and signal transmission through the Internet. The open signal output device may be provided in a place away from a house or the like provided with a door opening device having a door structure, or may be provided in the same house or the like. An earthquake or other disaster where external force is applied to the door structure, for example in the case of an earthquake, means the initial stage where the earthquake actually started shaking. It can be detected by the output signal of the sensor. An earthquake or other disaster where external force is applied to the door structure is expected when such a disaster is expected for some reason. For example, the main shock is predicted by initial tremors in a series of earthquakes. , Predicting the arrival of S-waves that arrive later than usual when P-waves with high propagation speed are detected, predicting the occurrence of earthquakes in response to abnormal animal reactions, etc. . For example, a vibration sensor is used to detect vibration.

この扉構造の扉開放装置は、扉２０の開き角度が、扉２０の回動側端部２２と扉枠１０との間に指、手又はバールその他のこじ開け用工具が差し込まれる隙間Ｃができる程度の開き角度となるように構成している。この実施形態の場合、開装置１２０がリミットスイッチを備えており、アーム１２２が上記開き角度になると、このリミットスイッチの作動を受けて駆動装置１２３を停止し、アーム１２２の回動が停止するようにしている。こうせずに災害用開制御装置１３０により駆動装置１２３の作動を制御してアーム１２２が上記開き角度になるように駆動装置１２３を制御するようにしてもよい。   In the door opening device of this door structure, the opening angle of the door 20 is such that a gap C is inserted between the turning side end 22 of the door 20 and the door frame 10 into which a finger, hand, bar or other prying tool is inserted. It is configured to have a degree of opening angle. In the case of this embodiment, the opening device 120 includes a limit switch. When the arm 122 reaches the opening angle, the driving device 123 is stopped by the operation of the limit switch, and the rotation of the arm 122 is stopped. I have to. Instead of this, the operation of the driving device 123 may be controlled by the disaster opening control device 130 to control the driving device 123 so that the arm 122 has the above opening angle.

この扉構造の扉開放装置は、開いた扉が閉じる方向へ外力を受けても扉が閉じないように構成している。この実施形態の場合、図８に示すように、上記開装置１２０は、先に説明したように、本体１２１と、アーム１２２と、駆動装置１２３とを備えている。そして、この駆動装置１２３は、アーム１２２の上記回動軸１２２ａに連動するギヤ１２３ａと、このギヤ１２３ａの中心軸と交差し且つ上記ギヤ１２３ａと噛み合うウォーム１２３ｂが設けられた出力軸１２３ｃを有してこれを回転駆動する電動機、油圧モータその他の回転駆動装置１２３ｄとを備えており、この構成により、開いた扉２０が閉じる方向へ外力を受けても扉２０が閉じないように構成している。この実施形態では、ギヤ１２３ａの中心軸と出力軸１２３ｃは交差するだけではなく、この中心軸又は出力軸の方向にみて直交している。ウォーム１２３ｂと噛み合うギヤ１２３ａはウォームギヤ又はウォームホイールなどと呼ばれる。また、アーム１２２の上記回動軸１２２ａに最終ギヤ１２２ｂを設けている。そして、上述した回動軸１２２ａに連動するギヤ１２３ａは、アーム１２２の上記回動軸１２２ａと平行に設けられた中心軸にその軸方向にずらして設けられ且つ相対的に動かない二枚のギヤよりなる二重ギヤのうちの一方であり、二重ギヤの他方のギヤ１２３ａを上記最終ギヤ１２２ｂに噛み合わせ、一方のギヤ１２３ａを上記回転駆動装置１２３ｄの出力軸１２３ｃのウォーム１２３ｂに噛み合せている。これによって回転駆動装置１２３ｄの回転はウォーム１２３ｂにより二重ギヤの一方のギヤ１２３ａに伝動され、他方のギヤ１２３ａから最終ギヤ１２２ｂに伝動され、アーム１２２を回動させる。二重ギヤの他方のギヤ１２３ａと、これに噛み合う最終ギヤ１２２ｂはギヤ形式を問わない。この場合、アーム１２２の上記回動軸１２２ａに連動するギヤ１２３ａを設けずに、アーム１２２の上記回動軸１２２ａに設けられた最終ギヤ１２２ｂを直接に回転駆動装置１２３ｄの出力軸１２３ｃのウォーム１２３ｂに噛み合せるようにしてもよい。そのときは最終ギヤ１２２ｂはウォームギヤ又はウォームホイールとすることになる。以上の構成により、アーム１２２の上記回動軸１２２ａに連動するギヤ１２３ａの回転力はウォーム１２３ｂによって受け止められ、このウォーム１２３ｂはギヤ１２３ａの中心軸と交差する回動軸を持つので、アーム１２２は回動せず、扉２０は閉じない。アーム１２２の上記回動軸１２２ａに設けられた最終ギヤ１２２ｂを直接に回転駆動装置１２３ｄの出力軸１２３ｃのウォーム１２３ｂに噛み合せるようにしたときには、アーム１２２の上記回動軸１２２ａに設けられた最終ギヤ１２２ｂの回転力はウォーム１２３ｂによって受け止められ、このウォーム１２３ｂは最終ギヤ１２２ｂが設けられた回動軸１２２ａと交差する回動軸を持つので、アーム１２２は回動せず、扉２０は閉じない。なお、アーム１２２の回動軸１２２ａと、二重ギヤの間にさらにギヤを介在させて多段のギヤ装置を構成してもよい。   The door opening device with this door structure is configured such that the door does not close even when the open door receives an external force in the closing direction. In the case of this embodiment, as shown in FIG. 8, the opening device 120 includes a main body 121, an arm 122, and a driving device 123 as described above. The driving device 123 has a gear 123a that is interlocked with the rotating shaft 122a of the arm 122, and an output shaft 123c that is provided with a worm 123b that intersects the central axis of the gear 123a and meshes with the gear 123a. An electric motor, a hydraulic motor, and other rotational drive devices 123d for rotationally driving the door. With this configuration, the door 20 is configured not to be closed even when an external force is applied in a direction in which the opened door 20 is closed. . In this embodiment, the center axis of the gear 123a and the output shaft 123c not only intersect, but are orthogonal to each other in the direction of the center axis or the output shaft. The gear 123a that meshes with the worm 123b is called a worm gear or a worm wheel. A final gear 122b is provided on the pivot shaft 122a of the arm 122. The gear 123a that is linked to the rotation shaft 122a described above is provided with two gears that are shifted in the axial direction of the central axis of the arm 122 provided in parallel with the rotation shaft 122a and that do not move relatively. The other gear 123a of the double gear meshes with the final gear 122b, and one gear 123a meshes with the worm 123b of the output shaft 123c of the rotary drive device 123d. . Accordingly, the rotation of the rotation driving device 123d is transmitted to one gear 123a of the double gear by the worm 123b, and is transmitted from the other gear 123a to the final gear 122b, and the arm 122 is rotated. The other gear 123a of the double gear and the final gear 122b that meshes with the other gear 123a do not matter. In this case, the final gear 122b provided on the rotation shaft 122a of the arm 122 is directly connected to the worm 123b of the output shaft 123c of the rotation drive device 123d without providing the gear 123a interlocking with the rotation shaft 122a of the arm 122. May be engaged with each other. At that time, the final gear 122b is a worm gear or a worm wheel. With the above configuration, the rotational force of the gear 123a interlocking with the rotational shaft 122a of the arm 122 is received by the worm 123b, and the worm 123b has a rotational shaft that intersects the central axis of the gear 123a. It does not rotate and the door 20 does not close. When the final gear 122b provided on the rotary shaft 122a of the arm 122 is directly meshed with the worm 123b of the output shaft 123c of the rotary drive device 123d, the final gear provided on the rotary shaft 122a of the arm 122 is provided. The rotational force of the gear 122b is received by the worm 123b, and the worm 123b has a rotation shaft that intersects the rotation shaft 122a on which the final gear 122b is provided. Therefore, the arm 122 does not rotate and the door 20 does not close. . Note that a multistage gear device may be configured by further interposing a gear between the rotating shaft 122a of the arm 122 and the double gear.

この扉構造の扉開放装置には、さらに、扉２０を閉じる方向へ付勢する閉装置１５０が設けられており、開装置１２０は閉装置１５０の閉じ力に抗して扉２０を開けるように構成されている。閉装置１５０は開いた扉２０を自動的に閉じる機能を発揮し、バネ力等により扉２０を閉じる方向へ付勢する。付勢力は保持装置３０のラッチ３１を凹部３５に入れる程度に設定されることが好ましい。   The door opening device of this door structure is further provided with a closing device 150 that urges the door 20 in the closing direction, so that the opening device 120 opens the door 20 against the closing force of the closing device 150. It is configured. The closing device 150 has a function of automatically closing the opened door 20 and biases the door 20 in the closing direction by a spring force or the like. The biasing force is preferably set to such an extent that the latch 31 of the holding device 30 is inserted into the recess 35.

従って、この第１実施形態に係る扉構造の扉開放装置においては、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から開信号が出力されると、災害用開制御装置１３０が開信号を受け、解除装置１１０及び開装置１２０が制御され、扉２０の閉じ状態への保持を解除し、扉２０が扉２０の回動側端部２２と扉枠１０との間に隙間Ｃがあく程度まで開く。そのため、隙間に指、手又はバールその他のこじ開け用工具を差し込めば扉２０をこじ開けることが可能になり、扉枠１０の開口の閉塞を回避して緊急避難路を確保できる。その場合、開装置１２０は、扉２０の開方向への動きを拘束しないので、扉２０をこじ開けることが可能である。しかも、扉２０における扉枠１０に嵌る部分を或る程度残るので、扉２０によって扉枠１０及びその周辺の構造の強度が支えられて扉構造周辺の構造物の崩壊が防止される。図７では扉２０に交差斜線で示した領域Ｗにおいて扉２０が扉枠１０に嵌っている。   Therefore, in the door opening device of the door structure according to the first embodiment, an open signal is output from an open signal output device provided separately in the event of an earthquake or other disaster where an external force acts on the door structure or when this disaster is expected. Is output, the disaster open control device 130 receives the open signal, the release device 110 and the open device 120 are controlled, the holding of the door 20 in the closed state is released, and the door 20 is turned to the rotation side of the door 20. The gap C is opened to an extent between the end 22 and the door frame 10. Therefore, if a finger, a hand, a bar, or other prying tool is inserted into the gap, the door 20 can be pry open, and the emergency evacuation path can be secured by avoiding blocking of the opening of the door frame 10. In that case, since the opening device 120 does not restrain the movement of the door 20 in the opening direction, the door 20 can be opened. In addition, since a portion of the door 20 that fits into the door frame 10 remains to some extent, the door 20 supports the strength of the door frame 10 and the surrounding structure, and prevents the structure around the door structure from collapsing. In FIG. 7, the door 20 is fitted to the door frame 10 in a region W indicated by crossed diagonal lines.

本発明は開装置の構造を限定するものではなく、開装置は、扉を開方向への拘束なく開く機能を発揮する装置であればよい。しかし、上記実施形態の場合、扉構造の扉開放装置は、開いた扉２０が閉じる方向へ外力を受けても扉が閉じないように構成している。このようにすれば、地震その他、扉構造に外力が作用する災害のとき又はこの災害が予想されるときに、開いた扉２０に、扉２０の開いた側から扉２０に何かが倒れかかってきて開いた扉２０を閉める外力が作用しても、このような力によって扉２０が閉じることがないので、本装置本来の脱出手段確保の機能が維持される。   The present invention does not limit the structure of the opening device, and the opening device may be any device that exhibits a function of opening the door without restriction in the opening direction. However, in the case of the said embodiment, the door opening apparatus of a door structure is comprised so that a door may not close, even if it receives external force in the direction where the opened door 20 closes. In this way, in the event of an earthquake or other disaster where an external force acts on the door structure, or when this disaster is expected, something will fall on the door 20 from the open side of the door 20 to the door 20. Even if an external force that closes the opened door 20 is applied, the door 20 is not closed by such a force, so that the function of securing the escape means inherent to the present apparatus is maintained.

本発明は、開いた扉が閉じる方向へ外力を受けても扉が閉じないようにする機能を発揮させるために開装置が具備する構造を限定するものではない。一例を挙げれば、シリンダとこのシリンダにスライドできるように嵌挿されたピストンとを備え、このシリンダ及びピストンのうち一方を開装置の本体に連結し他方を扉に連結し、シリンダとピストンとにより形成された空間に油圧又は空圧等を供給したりこれを空間に連通するリリーフ弁からリリーフすることで扉の開け閉めを行い、リリーフ弁を閉めることで開いた扉が閉じる方向へ外力を受けても扉が閉じないようにすることができる。これに対し、第１実施形態の扉構造の扉開放装置は、開装置１２０が、扉閉じ側において扉枠１０その他、扉２０の周辺に設けられた本体１２１と、この本体１２１に、基端がほぼ上下に延びる回動軸１２２ａのまわりに回動可能に設けられ、先端で扉２０を押すアーム１２２と、本体１２１に設けられ、アーム１２２を回動させる駆動装置１２３とを備えており、この駆動装置１２３が、アーム１２２の上記回動軸１２２ａに連動するギヤ１２３ａと、この回動軸１２２ａと交差し且つ上記ギヤ１２３ａと噛み合うウォーム１２３ｂが設けられた出力軸１２３ｃを有してこれを回転駆動する回転駆動装置１２３ｄとを備えている。このようにすれば、回転駆動装置１２３ｄが出力軸１２３ｃを回転駆動すると、回転力がウォーム１２３ｂからギヤ１２３ａに伝わり、さらに回動軸１２２ａに伝わってアーム１２２を回動させ、アーム１２２の先端が扉２０を押してこれを開く。その場合、アーム１２２の先端と扉２０とは何ら連結関係を持たないことから、開装置１２０は扉２０に対して開方向への拘束を行わず、扉２０がアーム１２２から離れてそれ以上開くことが可能である。そして、開いた扉２０が閉じる方向へ外力を受けても、アーム１２２は回動せず、扉２０は閉じない。このような機能を比較的簡単な構造によって発揮させることができる。   The present invention does not limit the structure of the opening device in order to exhibit the function of preventing the door from closing even when the open door receives an external force in the closing direction. For example, a cylinder and a piston that is slidably inserted into the cylinder are provided. One of the cylinder and the piston is connected to the main body of the opening device, and the other is connected to the door. The door is opened and closed by supplying hydraulic pressure or pneumatic pressure to the formed space or by relieving it from the relief valve communicating with the space, and when the relief valve is closed, the open door receives an external force in the closing direction. However, the door can be prevented from closing. On the other hand, in the door opening device having the door structure of the first embodiment, the opening device 120 includes a main body 121 provided around the door frame 10 and the door 20 on the door closing side, and a base end of the main body 121. Includes an arm 122 that pushes the door 20 at the tip, and a driving device 123 that rotates the arm 122. The driving device 123 has an output shaft 123c provided with a gear 123a interlocking with the rotating shaft 122a of the arm 122 and a worm 123b that intersects the rotating shaft 122a and meshes with the gear 123a. And a rotational driving device 123d for rotational driving. In this way, when the rotational drive device 123d rotationally drives the output shaft 123c, the rotational force is transmitted from the worm 123b to the gear 123a, further transmitted to the rotational shaft 122a, and the arm 122 is rotated. Push the door 20 to open it. In that case, since the distal end of the arm 122 and the door 20 do not have any connection relationship, the opening device 120 does not restrain the door 20 in the opening direction, and the door 20 opens further away from the arm 122. It is possible. Even if the open door 20 receives an external force in the closing direction, the arm 122 does not rotate and the door 20 does not close. Such a function can be exhibited by a relatively simple structure.

本発明は閉装置を設けない実施形態を含む。しかし、上記実施形態の場合、さらに、扉２０を閉じる方向へ付勢する閉装置１５０が設けられており、開装置１２０は閉装置１５０の閉じ力に抗して扉２０を開けるように構成されている。このようにすれば、災害用開制御装置１３０による上記制御が解除されたときに、閉装置１５０によって扉２０が閉じることができ、無意味に扉２０が開き続けることが防止される。その場合、災害用開制御装置１３０による上記制御が解除されたときに開装置１２０の駆動装置１２３の回転駆動装置１２３ｄを逆回転させてアーム１２２を扉２０が閉じたときの位置に復帰させることが必要となる。   The invention includes embodiments that do not provide a closing device. However, in the case of the above-described embodiment, the closing device 150 that biases the door 20 in the closing direction is further provided, and the opening device 120 is configured to open the door 20 against the closing force of the closing device 150. ing. In this way, when the control by the disaster opening control device 130 is released, the door 20 can be closed by the closing device 150, and it is prevented that the door 20 keeps opening without meaning. In that case, when the control by the disaster opening control device 130 is released, the rotation driving device 123d of the driving device 123 of the opening device 120 is reversely rotated to return the arm 122 to the position when the door 20 is closed. Is required.

次に、第２の実施形態に係る扉構造の扉開放装置を説明する。この扉構造の扉開放装置は、扉枠１０と、この扉枠１０を開け閉めし、閉じたときに扉枠１０に嵌るようにほぼ上下に延びる軸２１のまわりに回動可能に設けられた扉２０と、扉２０を閉じ状態に保持する保持装置３０とを備えた扉構造に設けられる扉開放装置であって、これらの前提は第１実施形態の前提と同様であるから、これらの部材には第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。また、第２実施形態に係る扉構造の扉開放装置は、扉２０の閉じ状態への保持を解除する解除装置１１０と、扉２０を、開方向への拘束なく開く開装置１２０とを備えており、さらに、開いた扉が閉じる方向へ外力を受けても扉が閉じないように構成していることも第１の実施形態と同様であるから、これらの部材にも第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。また、開装置が、扉閉じ側において扉枠その他、扉の周辺に設けられた本体と、この本体に、基端がほぼ上下に延びる回動軸のまわりに回動可能に設けられ、先端で扉を押し又は引くアームと、本体に設けられ、アームを回動させる駆動装置とを備えており、この駆動装置が、アームの上記回動軸に設けられたギヤ又はアームの上記回動軸に連動するギヤと、この回動軸と交差し且つ上記ギヤと噛み合うウォームが設けられた出力軸を有してこれを回転駆動する回転駆動装置とを備えていることも第１の実施形態と同様であるから、これらの部材にも第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。さらに、扉２０を閉じる方向へ付勢する閉装置１５０が設けられており、開装置１２０は閉装置１５０の閉じ力に抗して扉２０を開けるように構成されている。これらの構成も第１の実施形態と同様であるから、これらの部材にも第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。   Next, a door opening device having a door structure according to the second embodiment will be described. The door opening device of this door structure is provided so as to be rotatable around a door frame 10 and a shaft 21 that opens and closes the door frame 10 and extends substantially vertically so as to fit into the door frame 10 when the door frame 10 is closed. A door opening device provided in a door structure including a door 20 and a holding device 30 that holds the door 20 in a closed state, and these assumptions are the same as those in the first embodiment. Are denoted by the same reference numerals as in the first embodiment, and the description of the first embodiment is cited as it is. Moreover, the door opening apparatus of the door structure which concerns on 2nd Embodiment is provided with the cancellation | release apparatus 110 which cancels | releases holding | maintenance to the closed state of the door 20, and the opening apparatus 120 which opens the door 20 without the restriction | limiting in an opening direction. In addition, since the door is not closed even when the open door receives an external force in the closing direction, it is the same as in the first embodiment, so these members are also in the case of the first embodiment. The description of the first embodiment is directly quoted. Further, an opening device is provided on the door closing side so as to be rotatable around a door frame and other main body provided around the door, and on the main body, a rotation axis extending substantially vertically up and down. An arm that pushes or pulls the door, and a drive device that is provided in the main body and rotates the arm, and this drive device is provided on the rotation shaft of the arm or the rotation shaft of the arm. Similarly to the first embodiment, the apparatus includes an interlocking gear, and a rotation driving device that has an output shaft provided with a worm that intersects with the rotation shaft and meshes with the gear, and rotates the output shaft. Therefore, these members are also denoted by the same reference numerals as those in the first embodiment, and the description of the first embodiment is directly cited. Further, a closing device 150 that biases the door 20 in the closing direction is provided, and the opening device 120 is configured to open the door 20 against the closing force of the closing device 150. Since these configurations are the same as those in the first embodiment, the same reference numerals as those in the first embodiment are given to these members, and the description of the first embodiment is directly cited.

そして、第２実施形態に係る扉構造の扉開放装置の場合、第１実施形態における災害用開制御装置に代えて、第２実施形態のための災害用開制御装置１３０を備えている。この災害用開制御装置１３０は、電源、電気回路等を備え、解除装置１１０及び開装置１２０に接続され、これらを制御する。この実施形態の場合、災害用開制御装置１３０は開装置１２０の本体１２１に内蔵され、電線等を介して解除装置１１０及び開装置１２０に電気的に接続されている。その接続形態としては電気的な接続、電波通信による接続、光通信による接続その他の形態がある。災害用開制御装置１３０は、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から出力される開信号を受けると、扉２０の閉じ状態への保持を解除して扉２０を開くように解除装置１１０及び開装置１２０を制御するように構成されている。この実施形態の場合、開信号出力装置からの開信号の発信形態は、電波による信号の発信である。従って、災害用開制御装置１３０は、開信号を受信する受信回路を含んでいる。それ以外の開信号の発信形態として、例えば電話線、光ファイバー、専用線等を通じた信号の伝送、インターネットを通じた信号の伝送が例示される。開信号出力装置は扉構造の扉開放装置を設けた家屋等から離れた場所に設けてもよいし、同じ家屋等に設けてもよい。水害その他、扉枠の外に水が流入する災害のときとは、水害の場合を例にとると、実際に扉枠の外に水が流入し始めた初期の段階を意味しており、これは例えば水位などを検出する水位センサの出力信号により検出することができる。水害その他、扉枠の外に水が流入する災害が予想されるときとは、なんらかの根拠でこのような災害が予想されるときであり、これには例えば天気予報の大雨注意報等を受けて水害を予想すること、地震を検知したときにそれよりも遅れて届く津波の到来を予想することなどが含まれる。振動の検出には例えば感振センサが用いられる。   In the case of the door opening device having the door structure according to the second embodiment, the disaster opening control device 130 for the second embodiment is provided instead of the disaster opening control device in the first embodiment. The disaster opening control device 130 includes a power source, an electric circuit, and the like, and is connected to the release device 110 and the opening device 120 to control them. In the case of this embodiment, the disaster opening control device 130 is built in the main body 121 of the opening device 120 and is electrically connected to the releasing device 110 and the opening device 120 via an electric wire or the like. The connection forms include electrical connection, connection by radio wave communication, connection by optical communication, and other forms. When the disaster open control device 130 receives an open signal output from an open signal output device provided separately in the event of a flood or other disaster where water flows outside the door frame or when this disaster is expected, The release device 110 and the opening device 120 are controlled so as to release the holding of the closed state 20 and open the door 20. In the case of this embodiment, the transmission form of the open signal from the open signal output device is transmission of a signal by radio waves. Therefore, the disaster opening control device 130 includes a receiving circuit that receives the opening signal. Other forms of open signal transmission include, for example, signal transmission through a telephone line, an optical fiber, a dedicated line, etc., and signal transmission through the Internet. The open signal output device may be provided in a place away from a house or the like provided with a door opening device having a door structure, or may be provided in the same house or the like. In the case of a flood or other disaster where water flows into the outside of the door frame, taking the case of flood as an example, it means the initial stage where water actually began to flow out of the door frame. Can be detected by, for example, an output signal of a water level sensor that detects a water level or the like. A flood or other disaster that causes water to flow outside the door frame is when such a disaster is expected for some reason. For example, in response to a heavy rain warning in the weather forecast, etc. This includes predicting flood damage and predicting the arrival of a tsunami that arrives later when an earthquake is detected. For example, a vibration sensor is used to detect vibration.

この扉構造の扉開放装置は、扉２０の開き角度が、扉２０の回動側端部２２と扉枠１０との間に、扉２０の内側へ水を導入できる隙間Ｃができる程度の開き角度となるように構成している。この実施形態の場合、開装置１２０がリミットスイッチを備えており、アーム１２２が上記開き角度になると、このリミットスイッチの作動を受けて駆動装置１２３を停止し、アーム１２２の回動が停止するようにしている。こうせずに災害用開制御装置１３０により駆動装置１２３の作動を制御してアーム１２２が上記開き角度になるように駆動装置１２３を制御するようにしてもよい。   In the door opening device of this door structure, the opening angle of the door 20 is such that a gap C that allows water to be introduced into the inside of the door 20 is formed between the rotation side end portion 22 of the door 20 and the door frame 10. It is configured to have an angle. In the case of this embodiment, the opening device 120 includes a limit switch. When the arm 122 reaches the opening angle, the driving device 123 is stopped by the operation of the limit switch, and the rotation of the arm 122 is stopped. I have to. Instead of this, the operation of the driving device 123 may be controlled by the disaster opening control device 130 to control the driving device 123 so that the arm 122 has the above opening angle.

従って、この第２実施形態に係る扉構造の扉開放装置においては、水害その他、扉枠の外に水が流入する災害のとき又はこの災害が予想されるときに別に設けた開信号出力装置から開信号が出力されると、災害用開制御装置１３０が開信号を受け、解除装置１１０及び開装置１２０が制御され、扉２０の閉じ状態への保持を解除し、扉２０が扉２０の回動側端部２２と扉枠１０との間に隙間Ｃがあく程度まで開く。そのため、隙間Ｃから扉２０の内側へ水が導入され、扉２０の外側と内側の水位差がほぼ無くなり、脱出時に扉２０を人力で開くことができるようになる。その場合、開装置１２０は、扉２０の開方向への動きを拘束しないので、扉２０を開けることが可能である。また、隙間Ｃが最小限に抑えられるため、急激に水位が上がってくるなかで水の静圧、動圧を受けつつこれに抗して扉２０を開けるときでも、扉２０を開けるための開装置１２０が大きな負荷を受けることが防止され、損傷を受けたり、それによって不意に扉２０が閉まるという事態が回避される。しかも、隙間Ｃが最小限に抑えられることで、扉２０を開けてから水が流入してきたときでも、水流によって開いた扉２０が大きな力を受けにくく、扉２０を開けるための開装置１２０が大きな負荷を受けることが防止され、損傷を受けたり、それによって不意に扉２０が閉まるという事態が回避される。   Therefore, in the door opening device of the door structure according to the second embodiment, from an open signal output device provided separately in the event of a flood or other disaster where water flows outside the door frame or when this disaster is expected When the opening signal is output, the disaster opening control device 130 receives the opening signal, the release device 110 and the opening device 120 are controlled, the holding of the door 20 in the closed state is released, and the door 20 is turned on the door 20. Open to the extent that there is a gap C between the moving end 22 and the door frame 10. Therefore, water is introduced into the inside of the door 20 from the gap C, and the difference in water level between the outside and the inside of the door 20 is almost eliminated, so that the door 20 can be opened manually when escaping. In that case, since the opening device 120 does not restrain the movement of the door 20 in the opening direction, the door 20 can be opened. In addition, since the gap C is minimized, even when the door 20 is opened against the static pressure and dynamic pressure of water while the water level suddenly rises, the opening for opening the door 20 is avoided. The device 120 is prevented from receiving a heavy load, and the situation where the door 20 is closed unexpectedly due to damage is avoided. In addition, since the gap C is minimized, even when water flows in after the door 20 is opened, the door 20 opened by the water flow is less likely to receive a large force, and the opening device 120 for opening the door 20 is provided. It is prevented from receiving a large load, and a situation in which the door 20 is closed due to damage or unexpectedly is avoided.

本発明は開装置の構造を限定するものではなく、開装置は、扉を開方向への拘束なく開く機能を発揮する装置であればよい。しかし、上記実施形態の場合、扉構造の扉開放装置は、開いた扉２０が閉じる方向へ外力を受けても扉２０が閉じないように構成している。このようにすれば、水害その他、扉枠１０の外に水が流入する災害のとき又はこの災害が予想されるときに、開いた扉２０に、扉２０の開いた側から水圧がかかってきて開いた扉を閉める外力が作用しても、このような力によって扉２０が閉じることがないので、本装置本来の水導入の機能が維持される。その他、閉装置、開装置などの構成から導かれる作用及び効果については第１実施形態のときと同様である。   The present invention does not limit the structure of the opening device, and the opening device may be any device that exhibits a function of opening the door without restriction in the opening direction. However, in the case of the said embodiment, the door opening apparatus of a door structure is comprised so that the door 20 may not close, even if it receives external force in the direction in which the opened door 20 closes. In this way, in the event of a flood or other disaster where water flows into the outside of the door frame 10 or when this disaster is expected, water pressure is applied to the opened door 20 from the opened side of the door 20. Even if an external force that closes the opened door is applied, the door 20 is not closed by such a force, so that the original water introduction function of the present apparatus is maintained. In addition, the operations and effects derived from the configuration of the closing device, the opening device, and the like are the same as in the first embodiment.

図９は第３の実施形態に係る扉構造の扉開放装置を示す。この扉構造の扉開放装置は、扉枠１０と、この扉枠１０を開け閉めし、閉じたときに扉枠１０に嵌るようにほぼ上下に延びる軸２１のまわりに回動可能に設けられた扉２０と、扉２０を閉じ状態に保持する保持装置３０とを備えた扉構造に設けられる扉開放装置であって、これらの前提は第１実施形態の前提と同様であるから、これらの部材には第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。また、第３実施形態に係る扉構造の扉開放装置は、扉２０の閉じ状態への保持を解除する解除装置１１０と、扉２０を、開方向への拘束なく開く開装置１２０とを備えており、さらに、扉２０を閉じる方向へ付勢する閉装置１５０が設けられており、開装置１２０は閉装置１５０の閉じ力に抗して扉２０を開けるように構成されている。これらの構成も第１の実施形態と同様であるから、これらの部材にも第１実施形態の場合と同一の符号を付し、第１実施形態の説明をそのまま引用する。   FIG. 9 shows a door opening device having a door structure according to the third embodiment. The door opening device of this door structure is provided so as to be rotatable around a door frame 10 and a shaft 21 that opens and closes the door frame 10 and extends substantially vertically so as to fit into the door frame 10 when the door frame 10 is closed. A door opening device provided in a door structure including a door 20 and a holding device 30 that holds the door 20 in a closed state, and these assumptions are the same as those in the first embodiment. Are denoted by the same reference numerals as in the first embodiment, and the description of the first embodiment is cited as it is. Moreover, the door opening device of the door structure which concerns on 3rd Embodiment is provided with the cancellation | release apparatus 110 which cancels | releases holding | maintenance to the closed state of the door 20, and the opening device 120 which opens the door 20 without the restriction | limiting in an opening direction. In addition, a closing device 150 that biases the door 20 in the closing direction is provided, and the opening device 120 is configured to open the door 20 against the closing force of the closing device 150. Since these configurations are the same as those in the first embodiment, the same reference numerals as those in the first embodiment are given to these members, and the description of the first embodiment is directly cited.

第１の実施形態に係る扉構造の扉開放装置は災害用開制御装置１３０を備え、扉２０の開き角度が、扉２０の回動側端部２２と扉枠１０との間に指、手又はバールその他のこじ開け用工具が差し込まれる隙間ができる程度の開き角度となるように構成した。これに対し、第３実施形態に係る扉構造の扉開放装置は、これに代えて、操作を受けると、扉２０の閉じ状態への保持を解除して扉２０を開くように解除装置１１０及び開装置１２０を制御する操作時開制御装置１４０を備え、扉２０の開き角度が、扉２０の回動側端部２２と扉枠１０との間に隙間Ｃができる程度の開き角度となるように構成している。操作時開制御装置１４０は押しボタン等の操作装置１４１を備えている。   The door opening device of the door structure according to the first embodiment includes a disaster opening control device 130, and the opening angle of the door 20 is between a rotating side end 22 of the door 20 and the door frame 10 with a finger or hand. Or it was comprised so that it might become an opening angle of the grade which can make the clearance gap in which a bar or other prying tool is inserted. On the other hand, the door opening device with the door structure according to the third embodiment, instead of this, upon receiving an operation, the release device 110 and the release device 110 so as to release the holding of the door 20 to the closed state and open the door 20. The operation opening control device 140 for controlling the opening device 120 is provided, and the opening angle of the door 20 is such that the opening angle is such that a gap C is formed between the rotation side end 22 of the door 20 and the door frame 10. It is configured. The operation opening control device 140 includes an operation device 141 such as a push button.

従って、この第３実施形態に係る扉構造の扉開放装置においては、身障者等が操作装置１４１を押すなどして操作時開制御装置１４０を操作すると、解除装置１１０及び開装置１２０が制御され、扉２０の閉じ状態への保持を解除し、扉２０が扉２０の回動側端部２２と扉枠１０との間に隙間Ｃがあく程度まで開く。そのため、扉２０の開き角度が小さいことから身障者等への扉２０の不用意な衝突が回避され、扉２０に近づいて押しボタン等の操作装置１４１により扉２０を開ける操作ができ、隙間Ｃから扉２０の向こうの様子を確認でき、隙間Ｃに指、手その他の身体部位又は杖、義手その他の器具を差し込んで引き、扉２０の回動側端部２２の端面など回動側端部２２の付近を手がかりに指、手、肩、脚その他の身体部位又は杖、義手その他の器具を当てるなどして引き、又は扉２０を押すことで扉２０を全開にすることができる。   Therefore, in the door opening device with the door structure according to the third embodiment, when the handicapped person operates the operation opening control device 140 by pressing the operation device 141 or the like, the release device 110 and the opening device 120 are controlled, The holding of the door 20 in the closed state is released, and the door 20 opens to the extent that there is a gap C between the rotation-side end 22 of the door 20 and the door frame 10. Therefore, since the opening angle of the door 20 is small, an inadvertent collision of the door 20 with a handicapped person can be avoided, and the door 20 can be opened by the operation device 141 such as a push button approaching the door 20. The state beyond the door 20 can be confirmed, and a finger, a hand or other body part or a cane, a prosthetic hand or other instrument is inserted and pulled into the gap C, and the rotation side end 22 such as the end surface of the rotation side end 22 of the door 20 is pulled. The door 20 can be fully opened by pulling by pushing a finger, a hand, a shoulder, a leg or other body part or a cane, a prosthetic hand or other device, or by pushing the door 20.

本発明は閉装置を設けない実施形態を含む。しかし、上記第３実施形態の場合、さらに、扉２０を閉じる方向へ付勢する閉装置１５０が設けられており、開装置１２０は閉装置１５０の閉じ力に抗して扉２０を開けるように構成されている。このようにすれば、操作時開制御装置１４０による上記制御が解除されたときに、閉装置１５０によって扉２０が閉じることができ、無意味に扉２０が開き続けることが防止される。   The invention includes embodiments that do not provide a closing device.
