本発明は、気密性や水密性及び耐火性を兼ね備えた扉を境に圧力差がある両開き扉で、圧力差が生じても開閉が簡易に可能な差圧緩和型迅速作動両開き扉に関するものである。 The present invention relates to a double-opening door having a pressure difference with a door having airtightness, watertightness, and fire resistance as a boundary, and a differential pressure relaxation type quick-opening double door that can be easily opened and closed even if a pressure difference occurs. is there.
近年、環境性能等の面から冷暖房機器の過剰な使用を抑える為に扉等の気密性等を高める事や火災時の避難の際に問題となる煙を遮断する事が一般化されてきた。しかし、病院や商業施設、ビル建造物等では、気密性を高める事によって扉を境に圧力差が生じ、容易に開閉出来ない扉が多く見られる様になってきた。 In recent years, from the viewpoint of environmental performance and the like, it has become common to increase the airtightness of doors and the like in order to suppress excessive use of air conditioning equipment, and to block smoke that becomes a problem during evacuation in the event of a fire. However, in hospitals, commercial facilities, building structures, etc., there are many doors that cannot be opened and closed easily due to a pressure difference caused by increasing the airtightness.
また、気密性の高い建物で火災等が発生した際には、排煙装置や熱による上昇気流等によって、通常よりも大きな圧力差によって扉の開閉が困難になり避難に支障になる等の事例が多くある為、多くの解決手段が用いられている。 In addition, when a fire, etc., occurs in a highly airtight building, the door may be difficult to open and close due to a larger pressure difference than usual due to a smoke exhauster or a rising airflow due to heat, etc. Because there are many, many solutions are used.
一つの防火戸で、閉めたまま採光と通風を選択できるようにして、扉本体の中にスライド空間を設け、その扉本体の幅方向中央部分に前記スライド空間を屋内外方向に貫通する開口部を設け、前記スライド空間にそれぞれ前記開口部とほぼ等幅の採光部と通風部とを有する小扉をスライド自在に備えた扉が提案されている（特許文献１参照）。 With one fire door, lighting and ventilation can be selected while closed, a slide space is provided in the door main body, and an opening that penetrates the slide space in the center in the width direction of the door main body indoors and outdoors There has been proposed a door provided with a small door slidably provided in the slide space and having a daylighting portion and a ventilation portion having substantially the same width as the opening (see Patent Document 1).
また、防火扉として通風用小扉付玄関ドアは、ドア本体と袖壁パネルとを並設して、袖パネルを中空構造とし、袖パネルの室外側に通気グリルを設け、且つ袖壁パネルの内部に火災時に通気グリル部と小扉との間を遮断するための防火用ダンパーを設けたものが提案されている（特許文献２参照）。 In addition, the entrance door with a small door for ventilation as a fireproof door has a door body and a sleeve wall panel arranged side by side, the sleeve panel has a hollow structure, a ventilation grill is provided on the outdoor side of the sleeve panel, and the sleeve wall panel There has been proposed one provided with a fire-proof damper for shutting off between the ventilation grille and the small door in the event of a fire (see Patent Document 2).
従来集合住宅の玄関扉には防犯や防火の為、自然換気を図ることが行なわれていない。玄関ドアを施錠しても、夏や春秋の中間期の風が通過する爽やかさが得られ、かつ風を通しても昆虫の侵入を防止し、視線を遮蔽し、火災時に特定防火設備として機能し、且つ防犯性能を確保する玄関扉と該玄関扉に取り付ける換気パネルが提供されている（特許文献３参照）。 Conventionally, the entrance doors of apartment buildings have not been naturally ventilated for crime prevention and fire prevention. Even if you lock the entrance door, you can get the refreshment that the wind of the middle period of summer and spring and autumn passes, and also prevent the invasion of insects through the wind, shield the line of sight, function as a specific fire prevention equipment in the event of a fire, In addition, an entrance door that secures crime prevention performance and a ventilation panel that is attached to the entrance door are provided (see Patent Document 3).
防火区画の通路に設置され常時閉状態に付勢される防火扉と、開放操作することにより前記防火扉の開放を可能とするドアーノブとを備えた防火扉装置において、前記防火扉に開口部を設け、ドアーノブの開放操作で開放され、ドアーノブの操作終了で閉鎖される差圧緩和機構を前記開口部に設けた防火扉装置が提案されている（特許文献４参照）。 A fire door apparatus comprising a fire door that is installed in a passage of a fire prevention zone and is normally biased and a door knob that allows the fire door to be opened by opening the fire door, wherein the fire door includes an opening. There has been proposed a fire door apparatus that is provided with a differential pressure relaxation mechanism provided in the opening, which is opened by opening the door knob and closed by the end of the operation of the door knob (see Patent Document 4).
扉を吊元扉とこの吊元扉に軸支される戸先扉とに左右で２分割して折り戸形式の扉とし、戸先扉を差圧緩和機構とするもので、平時は２枚の扉を一体として作動させ、差圧発生時は開放力を低減させるために戸先扉を先に開けることが可能で、操作性に優れる差圧緩和機構付き扉装置が提供されている（特許文献５参照）。 The door is divided into a left door and a door door pivotally supported by the suspension door to form a folding door type door, and the door door is a differential pressure relief mechanism. A door device with a differential pressure relief mechanism is provided that allows the door to be opened first in order to reduce the opening force when differential pressure is generated. Reference 5).
このような事情に鑑み、給気をすることなしに差圧をなくすことにより、扉の開放を容易にできるようにした扉装置で、差圧扉の均圧装置は、扉に開口部を開閉する蓋体を固定し、この作動軸装置にハンドルを設け、ハンドルを回転させることにより、蓋体を開放するものである。これらの装置は、扉の両面に差圧があっても、取手、ダンパーあるいは蓋体を開放することにより、扉の両面の差圧を解消して、扉を簡単に開放できるようにしたものが提案されている（特許文献６参照）。 In view of these circumstances, a door device that facilitates the opening of the door by eliminating the differential pressure without supplying air. The pressure equalizing device for the differential pressure door opens and closes the opening on the door. The lid is fixed, the handle is provided on the operating shaft device, and the handle is rotated to open the lid. These devices are designed so that even if there is a differential pressure on both sides of the door, the door, the damper or the lid can be opened to eliminate the differential pressure on both sides of the door so that the door can be opened easily. It has been proposed (see Patent Document 6).
上述した従来の扉装置の内、差圧開放式扉装置は、扉に室内外を連通する連通口を設け、この連通口を塞ぎ得る取手を扉枠に回転可能に固定し、前記取手が連通口を常時塞ぐように付勢したものである。また、大型危険地域の設備の扉は、扉に開口を設け、この開口に開閉自在のダンバーを固定し、このダンバーにダンパー開放手段を取付けた扉が提案されている（特許文献７参照）。 Among the conventional door devices described above, the differential pressure release type door device is provided with a communication port that communicates the interior and exterior of the door, and a handle that can block the communication port is rotatably fixed to the door frame, and the handle communicates. It is energized to always close the mouth. Moreover, the door of the installation of the large danger area has provided the door which provided the opening in the door, fixed the openable / closable damper to this opening, and attached the damper open | release means to this damper (refer patent document 7).
従来集合住宅の玄関扉には防火の為、ガラリなどの開口を設けて自然換気を図ることが行なわれていなく、自然換気は玄関の反対側のバルコニー側から行なわれている。その為、住戸内は袋状態になり夏や春秋の中間期の風が通過する爽やかさが得られない。自然換気を求める時は、玄関扉の下にパッキンを飼って、玄関扉を半開きにして自然換気をしているが、防犯上好ましくなく、又半開きのドアが廊下の通行の障害になるばかりでなく、廊下を通行する人に住戸の中を覗かれる不具合があった。 Conventionally, the entrance door of an apartment house has not been provided with an opening such as a louver to prevent natural ventilation for fire prevention, and natural ventilation is performed from the balcony side opposite the entrance. For this reason, the dwelling unit is in a bag state, and it is not possible to obtain the refreshingness that the wind in the middle of summer or spring and autumn passes. When natural ventilation is required, packing is kept under the entrance door, and the entrance door is opened halfway for natural ventilation. However, there was a problem that people passing through the corridors could look into the dwelling unit.
また通風と採光が可能なドアは、ドア本体の中にスライド空間を設け、そのドア本体の幅方向中央部分に前記スライド空間を屋内外方向に貫通する開口部を設け、前記開口部とほぼ等幅の採光部と通風部とを有する小扉をスライド自在に備えたものが提案されている（特許文献８参照）。 Further, the door capable of ventilation and lighting is provided with a slide space in the door main body, and an opening that penetrates the slide space in the indoor and outdoor directions is provided at the center in the width direction of the door main body. The thing provided with the small door which has the lighting part of the width | variety and the ventilation part so that sliding was possible was proposed (refer patent document 8).
また、省スペース化を行う為にトイレ等のブースの出入り口の両開き扉で、第一扉と第二扉が逆方向に開閉する両開き扉の同時開閉機構が提案されている。（特許文献９参照） In order to save space, a double-opening door simultaneous opening / closing mechanism has been proposed in which the first door and the second door are opened and closed in opposite directions at the door of a booth such as a toilet. (See Patent Document 9)
しかし、従来の第一扉と第二扉が逆方向に開閉する両開き扉は、防火性能上で必要な戸当たりと、戸じゃくりを有しておらず、召し合せ上部に隙間が生じてしまい、気密性及び防火性を有する事が困難であった。 However, the conventional double door that opens and closes the first door and the second door in the opposite direction does not have the door stop and door-shake necessary for fire prevention performance, and a gap is formed at the top of the summons. It was difficult to have airtightness and fire resistance.
また、地下にある扉は水害等によって地下に水が流入する事によって、扉を境に通常の気圧差よりも大きな圧力差が生じ、開閉困難になり避難が出来ないといった事例も報告されている。 In addition, there are reports of cases where the doors in the basement cause water to flow into the basement due to water damage, etc., resulting in a pressure difference greater than the normal pressure difference across the door, making it difficult to open and close and evacuating. .
よって、扉を境に圧力差が生じた場合は扉に何かしらの装置を組み込むか、別に空気の通気口を取付ける物しか無く、水害や小さな圧力差から大きな圧力差まで対応し、耐火性を有した可能な扉は存在しない。 Therefore, if there is a pressure difference between the doors, there is only something that can be installed in the door or a separate air vent, and it can handle water damage and small to large pressure differences. There is no possible door.
本発明は、日常で良く使用する扉で冷房機器の様な小さな差圧から、火災や水害の様に大きな差圧が生じる場合でも、容易に開閉が可能な扉が求められている。 There is a need for a door that can be easily opened and closed even when a large differential pressure occurs, such as a fire or water damage, from a small differential pressure such as a cooling device in a door that is often used in daily life.
一般に、差圧用ドア装置によると、幅方向の一方の側端部に取り付けられたヒンジを中心にドア枠に対して開閉自在となっている親ドアに、幅方向の他方の側端部まで達する子ドア部を同様に形成し、この子ドア部に、左右方向を軸方向とする中心軸を中心に反対側ドアを回動自在に配置しなければならず、また、反対ドアに、操作部材の操作によりドア枠に対し係脱する第１ラッチ部材と、親ドアに対し係脱する第２ラッチ部材とを設けなければならず、これによると、装置全体の構造が複雑となり、組立作業に多くの手間がかかることになる。 Generally, according to the differential pressure door device, the main door that can be opened and closed with respect to the door frame around the hinge attached to one side end in the width direction reaches the other side end in the width direction. A child door portion is formed in the same manner, and the opposite door must be rotatably arranged around the central axis with the left-right direction as the axial direction. The first latch member to be engaged / disengaged with respect to the door frame by the operation and the second latch member to be engaged / disengaged with respect to the parent door must be provided. It will take a lot of work.
従来の差圧によって差圧解除扉装置の問題点に鑑み、できるだけ差圧解除扉装置の構造を簡潔にして動作トラブルや故障の発生を極力抑えると共に、差圧管理が破綻するような親扉と子扉の２つの扉が同時開状態になることがない差圧用扉装置を提供されることが要望されている。 In view of the problems of the differential pressure release door device due to the conventional differential pressure, the structure of the differential pressure release door device is simplified as much as possible to minimize the occurrence of operational troubles and malfunctions, and the parent door where the differential pressure management breaks down It is desired to provide a differential pressure door device in which the two doors of the child door are not simultaneously opened.
従来の構成では、扉にかかる風圧力に対抗して扉を回動させなければならないので、差圧が大きい時や、扉が大きく圧力差が大きい場合には、扉の開閉に大きい力を要するといった問題があった。そこで、前記の問題を解決すべく案出されたものであって、扉の大きさや内外の差圧の大きさに影響されず、小さい力で差圧を調整することができる扉用差圧調整機構が期待されている。 In the conventional configuration, the door must be rotated against the wind pressure applied to the door. Therefore, when the differential pressure is large or when the door is large and the pressure difference is large, a large force is required to open and close the door. There was a problem. Therefore, it was devised to solve the above-mentioned problems, and it is possible to adjust the differential pressure with a small force without being influenced by the size of the door or the pressure difference inside and outside the door. The mechanism is expected.
しかしながら、上記した従来の室内外気圧差解消構造は、扉に別な扉を設けなければならないため、気密性や扉のデザイン性を低下させる欠点があった。また、扉には別な扉を開閉させる開閉板やこの開閉板を操作ハンドルの操作に連動させて作動させる昇降棒等の連動装置を設けなければならないため、機構が複雑となり、容易な取り付けができず、コストの増大する欠点があった。開閉板を設けることなく、室内外の差圧が解消できる開動助勢錠を提供し、もって、見栄え、気密性、防犯性及び安全性を低下させることなく、負圧によって開け難くなった扉の容易な開動を図ることも求められている。 However, the above-described conventional indoor / outdoor air pressure difference elimination structure has a drawback in that the airtightness and the design of the door are deteriorated because another door must be provided as the door. In addition, the door must be provided with an open / close plate that opens and closes another door, and an interlocking device such as a lifting bar that operates the open / close plate in conjunction with the operation of the operation handle. There was a disadvantage that the cost could not be increased. Providing an opening assisting lock that can eliminate the pressure difference inside and outside the room without providing an open / close plate, making it easy to open doors that are difficult to open due to negative pressure without deteriorating appearance, airtightness, security, and safety. It is also demanded to open up.
さらに、差圧扉の装置によれば、ハンドルを回してネジ式の作動軸装置で蓋体を扉から離すので、蓋体が扉から離れるのに時間がかり、上記二つの従来技術と同様に、火災時の避難用扉に適用することは好ましくなかった。
本発明は、上述した点に鑑み、ドアハンドルによる扉の開放操作のみで差圧をなくして容易に避難を可能とし、かつ確実に防火扉としての役割を果たす差圧用防火扉装置を提供することを目的としている。
Furthermore, according to the differential pressure door device, the handle is rotated and the lid is separated from the door by the screw-type operating shaft device, so it takes time for the lid to leave the door. It was not preferable to apply it to an evacuation door in the event of a fire.
In view of the above-described points, the present invention provides a differential pressure fire door device that allows easy evacuation without the differential pressure only by the door opening operation by the door handle, and surely serves as a fire door. It is an object.

本発明の差圧緩和型迅速作動両開き扉を、図面に基づいて説明する。図１は、差圧緩和型迅速作動両開き扉の正面図と平面図と縦断面図で、第一扉と第二扉が逆方向に開くようになっている。
図２は、第一扉と第二扉を連動させる為に、扉と吊り金具と連動軸と連動補助具と連結材が連動して作動する図である。
図３は、第一扉と第二扉を連動させる、いくつかの方法を図にしている。
The differential pressure relief type quick opening double door of the present invention will be described with reference to the drawings. FIG. 1 is a front view, a plan view, and a longitudinal sectional view of a differential pressure relief type quick-open double door, in which the first door and the second door are opened in opposite directions.
FIG. 2 is a diagram in which the door, the hanging bracket, the interlocking shaft, the interlocking auxiliary tool, and the connecting member operate in conjunction with each other in order to interlock the first door and the second door.
FIG. 3 illustrates several methods of interlocking the first door and the second door.
事務室と廊下を繋ぐ扉で、夏や冬などに空調機器等で内外に圧力差が生じる場所に設置されている縦２４００ｍｍ、横１８００アルミニウム製の両開き扉で、図１の示すように第一扉にはハンドルと自閉装置のフロアヒンジと吊り金具を備え、第二扉には自動フランス落としと下部に自閉装置と吊り金具を兼用したフロアヒンジと上部にセンター吊りの吊り金具を備えている。 A door that connects the office to the corridor. It is a double door made of 2400 mm long and 1800 mm wide aluminum that is installed in a place where a pressure difference occurs inside and outside in the summer or winter. The door is equipped with a handle and a self-closing device floor hinge and a hanging bracket, the second door is equipped with an automatic French drop, a floor hinge that combines the self-closing device and the hanging bracket at the bottom, and a center hanging suspension fitting at the top. Yes.
枠には、図５に示すように各扉の開閉方向の逆側に戸当たりと備え、その各戸当たりは２ｍｍのアルミニウム製の板で連結されており、これによって防火性と気密性を有している。 As shown in FIG. 5, the frame is provided with a door stop on the opposite side in the opening and closing direction of each door, and each door stop is connected by a 2 mm aluminum plate, thereby having fire resistance and airtightness. ing.
各扉と枠には気密性を有するために、図６〜８の様に枠には縦枠と戸当たり部にクロロプレンゴム製の気密材と、各扉には扉の下側と召し合わせ部にクロロプレンゴム製の気密材を備えている。 Since each door and frame is airtight, as shown in FIGS. 6-8, the frame has a vertical frame and a door sealing part made of chloroprene rubber. It has an airtight material made of chloroprene rubber.
第一扉と第二扉は逆方向に開閉し、図２に示すような各扉がプーリーと連結材と吊り金具とを図３Ａに示すようにキーとキー溝やイモネジ、軸端を四角にして固定してあり、固定された各装置が、ベルトの貼調整機構で調整したベルトを介して連動するように設置させた。 The first door and the second door open and close in the opposite direction, and each door as shown in FIG. 2 has a pulley, a connecting member, and a hanging bracket as shown in FIG. The fixed devices were installed so as to be linked via a belt adjusted by a belt sticking adjustment mechanism.
これによって、本来圧力によって開閉する際に負荷が生じていたが、第一扉と第二扉がプーリー付き連結材を連動して反対方向に開閉することによって、開閉力に圧力による負荷と付加が加わり、両扉の開閉が容易に可能となった。
特に病院など廊下でエアコンを稼働している境の扉がスムーズに開閉できるようになった。火災時の排煙装置や上昇気流、地下での水害等で成人男性でも開閉が困難な圧力差が生じた場合でも、第一扉もしくは第二扉の負荷と同じ開閉力が第二扉もしくは第一扉に付加される為、開閉が可能となった。
This caused a load when opening and closing due to pressure, but when the first door and the second door open and close the connecting material with pulleys in the opposite direction, the load and load due to pressure are added to the opening and closing force. In addition, both doors can be opened and closed easily.
