Description
本発明は、地震等の災害によって変形した建物のドア枠構造体が開放不能になった場合、室内に閉じ込められた人が自力で室外に脱出することができる手動式ドア開放装置に関する。 The present invention relates to a manual door opening device that allows a person trapped in a room to escape to the outside by himself / herself when the door frame structure of a building deformed due to a disaster such as an earthquake cannot be opened.
１９７６年に宮城県沖地震が発生し、当時の中高層集合住宅が戦後初めて大規模な地震による倒壊被害を被り、壁の損傷により玄関ドアが開かない事故が発生したことを契機に、玄関ドアに対する耐震性能を付加した機能ドアの質的需要ならびに多様化したニーズが高まると同時に、性能に対する考え方、評価方法の確立が求められるようになってきた。さらにその後、試験工法や性能基準のＪＩＳ規格が制定されてきて、現在ではマンションや建築物のおよそ７割程度の開閉ドアがクリアランス拡大タイプの耐震ドアとなっている。 In 1976, the Miyagi-ken-oki earthquake occurred, and the middle- and high-rise apartments were damaged by a large-scale earthquake for the first time after the war. At the same time as qualitative demand for functional doors with added seismic performance and diversified needs have increased, it has become necessary to establish a concept and evaluation method for performance. Since then, JIS standards for test methods and performance standards have been established, and about 70% of the open / close doors in condominiums and buildings are now earthquake-resistant doors with increased clearance.
しかしながら、上記のクリアランス拡大タイプや耐震ストライクを戸先枠に設けたタイプの耐震ドアは、密封性、防音性、保温性を備える間材等の質的機能の向上が求められ、今後は近代建築要素の多様化から新たな耐震機能を備えた耐震ドアの開発が望まれるものである。 However, the above-mentioned clearance-enhanced types and types of earthquake-resistant doors that are equipped with an earthquake-resistant strike on the door frame are required to improve the qualitative functions such as sealing materials that provide sealing, soundproofing, and heat insulation properties. From the diversification of elements, the development of a seismic door with a new seismic function is desired.
上記における新たな耐震ドアの要求を満たすべく、ドア枠ならびに開閉ドアの当接面をそれぞれテーパ状にして耐震機能を備えた耐震ドアの提案がなされている。例えば、ドア枠ならびに開閉ドアの当接面をそれぞれテーパ状にした「耐震ドア」（特許文献１参照）が提案されている。
しかしながら該提案は、ドア枠ならびに開閉ドアの当接面をそれぞれテーパ状にすることによって耐震機能を持たせているが、該施工および使用に際しては下記に示す問題点が指摘されるものであった。
（１）ドア枠とテーパ状の開閉ドアが一対構造であるため、マンションやコンクリート建築物の新築用の耐震ドアとして限定され、既存のマンションやコンクリート集合住宅における耐震ドアの改造工事においては、高額な工事費用と多くの工事日程を必要とするといった問題。
（２）地震等の外部応力よる局部変形を耐震ドアの施錠部に受けた場合、施錠の歪みによって開閉ドアが開閉しない可能性があるといった問題。
（３）ドア枠の底面下部テーパ部の勾配段差により、バリアフリー化が図れないといった問題。
（４）開閉ドア周辺部、特に床面がテーパ状の尖端形状を有しているため、安全性、使い易さ、美観性が劣るといった問題。
（５）ドア枠ならびに開閉ドアのテーパ部に連なる平坦部が、地震等の外部応力によって面内変形若しくは局部変形を受けた場合、ドア枠と開閉ドアが咬み合って開閉しない可能性があるといった問題。
In order to satisfy the requirements for the new earthquake-resistant door described above, there has been proposed an earthquake-resistant door having an earthquake-resistant function in which the contact surface of the door frame and the opening / closing door is tapered. For example, a “seismic door” (see Patent Document 1) in which the contact surfaces of the door frame and the open / close door are tapered has been proposed.
However, although this proposal has an earthquake-resistant function by making the contact surfaces of the door frame and the open / close door tapered, the following problems have been pointed out in the construction and use. .
(1) Because the door frame and tapered opening / closing door have a pair structure, it is limited as a seismic door for new construction of condominiums and concrete buildings. Problem that requires a lot of construction costs and a lot of construction schedules.
(2) When the local deformation due to an external stress such as an earthquake is received by the locking part of the earthquake resistant door, there is a possibility that the opening / closing door may not be opened / closed due to the distortion of the locking.
(3) There is a problem that barrier-free cannot be achieved due to the gradient step of the bottom bottom tapered portion of the door frame.
(4) Since the periphery of the open / close door, particularly the floor surface, has a tapered pointed shape, there is a problem that safety, ease of use, and aesthetics are inferior.
(5) If the flat part connected to the door frame and the tapered part of the open / close door is subject to in-plane deformation or local deformation due to an external stress such as an earthquake, the door frame and the open / close door may bite and not open / close. problem.
また、「室内閉じ込め防止用の構造体及びそのためのドア改造部材」（特許文献２参照）が提案されている。
しかしながら該提案は、室内閉じ込め防止用のドア構造体に関して上記同様の問題点と共に、ドア改造部材に関しては下記の問題が指摘されるものであった。
（１）改造部材が後付けであるため、開閉ドアの外観的美観が損なわれるといった問題。
（２）既存の開閉ドアの上下方向に対してのみの耐震機能改造工事であるため、水平横方向からの地震等の外部応力による面内変形若しくは局部変形に弱いといった問題。
（３）開閉ドア下部に設けられたローラーが面内変形若しくは局部変形によって破損した場合、ローラーを構成する部品類が枠体と開閉ドア間に挟まって開閉しない可能性があるといった問題。
（４）ローラーの下部に設けられるテーパ部を有するドア改造部材によってバリアフリー化が図れない構造であると共に、密封性、防音性、保温性に劣るといった問題。
（５）枠体および既存のドア加工の改造工事における施工費用の問題。
Further, “a structure for preventing indoor confinement and a door remodeling member therefor” (see Patent Document 2) has been proposed.
However, in this proposal, the following problems are pointed out with respect to the door remodeling member as well as the same problems as described above regarding the door structure for preventing indoor confinement.
(1) Since the modified member is retrofitted, the appearance and appearance of the open / close door is impaired.
(2) Since it is a seismic function modification work only in the vertical direction of the existing open / close door, there is a problem that it is vulnerable to in-plane deformation or local deformation due to external stress such as an earthquake from the horizontal direction.
(3) When the roller provided in the lower part of the opening / closing door is damaged due to in-plane deformation or local deformation, there is a possibility that parts constituting the roller may not be opened / closed between the frame and the opening / closing door.
(4) There is a problem that a barrier-free structure cannot be achieved by a door remodeling member having a tapered portion provided at the lower portion of the roller, and the sealing property, soundproofing property, and heat retaining property are inferior.
(5) Problem of construction cost in frame and existing door modification work.
また、開閉ドアの内側に脱出用の開口部が設けられた「耐震ドア」（特許文献３参照）が提案されている。係る提案は、地震等の災害により室内側よりドアが開かない場合、閉じ込められた人が脱出用の開口部から室外に脱出できるようにした耐震ドアであるが、開閉ドア内に開口部を形成する閉鎖パネルや係止機構を設けることは製造コストの高騰に繋がり、且つ該閉鎖パネルの防犯上の安全性の問題や美観性の問題が残るものであり、さらに係止機構を構成する解除レバー、ピン、連結杆が地震等の影響を受けて解除できなくなる可能性があった。 In addition, an “earthquake-resistant door” (see Patent Document 3) in which an opening for escape is provided inside the open / close door has been proposed. The proposal is an earthquake-resistant door that allows a confined person to escape from the opening for escape when the door does not open from the indoor side due to a disaster such as an earthquake. Providing a closing panel and a locking mechanism that lead to an increase in manufacturing cost, and there are still security problems and aesthetic problems of the closing panel, and a release lever constituting the locking mechanism There was a possibility that the pins and connecting rods could not be released due to the earthquake.
また、扉に過大な荷重が加えられたとき破断する構造を有する「耐震蝶番」（特許文献４参照）が提案されている。係る提案は、扉に過大な荷重が加えられたとき、ドア枠と開閉ドアを繋ぐ蝶番自体が破断するようにした耐震用の蝶番であるが、地震等の災害によりドア枠と開閉ドアを繋ぐ蝶番自体が複雑に咬み合って破断した場合、速やかに開閉ドアを排除できない可能性があるものであり、また地震と同時に開閉ドアがドア枠から外れて二次災害を起こす可能性があった。 In addition, an “earthquake-resistant hinge” (see Patent Document 4) having a structure that breaks when an excessive load is applied to the door has been proposed. The proposal is an earthquake-resistant hinge that breaks the hinge itself that connects the door frame and the open / close door when an excessive load is applied to the door, but connects the door frame and the open / close door due to a disaster such as an earthquake. When the hinge itself bites in a complicated manner and breaks, there is a possibility that the opening / closing door cannot be quickly removed, and at the same time as the earthquake, the opening / closing door may come off the door frame and cause a secondary disaster.
また、開閉ドアの一端にカム式のドア開放装置を取り付けた「ドア開放装置」（特許文献５参照）や、「ドア開放装置」（特許文献６参照）などが提案されている。係る提案は、開放不能になった開閉ドアを、てことカムの原理を利用して開放しようとするものであるが、日常的に開け閉めされる開閉ドアにドア開放装置が常時備え付けられているため、使い勝手や安全性、外観美観性に欠けるものであり、さらに左右の取り付け仕様が異なると共に内開きの開閉ドアには対応できないなどの問題があった。 In addition, a “door opening device” (see Patent Document 5) in which a cam-type door opening device is attached to one end of an open / close door, a “door opening device” (see Patent Document 6), and the like have been proposed. Such a proposal is intended to open an openable / closable door using the principle of a lever cam. However, a door opener is always provided for an open / close door that is opened and closed on a daily basis. For this reason, there are problems such as lack of convenience, safety, and appearance aesthetics, and different mounting specifications on the left and right sides and inability to accommodate an open / close door.
本出願人は、以上のような従来の耐震ドアにおける経済性、安全性、密封性、防音性、保温性に加えて設置工事の容易性の問題に着目し、それらの問題点を簡便且つ容易な手段で達成することができないものかという着想の下、地震等の災害によって変形した建物のドア枠構造体が開放不能になった場合、室内に閉じ込められた人が自力で室外に脱出することができる手動式のドア開放装置を開発し、本発明における「手動式ドア開放装置」の提案に至るものである。 The present applicant pays attention to the problems of ease of installation work in addition to the economy, safety, sealing performance, soundproofing, and heat insulation in the conventional seismic door as described above, and these problems are simple and easy. If the door frame structure of a building deformed by a disaster such as an earthquake becomes impossible to open under the idea of whether it can be achieved by appropriate means, people trapped in the room will escape outside by themselves. A manual door opening device that can be used is developed, and the “manual door opening device” according to the present invention is proposed.
