Description

本発明は、隔壁によって外部と隔絶され、前後方向に開閉可能な開き戸と、レールに案内されて左右方向にスライド移動可能な建具とを備えた閉鎖空間で、開き戸の開閉に伴う閉鎖空間の気圧変動によって建具に振動が生じるのを抑制する開き戸開閉時の建具振動抑制構造に関する。 The present invention is a closed space provided with a hinged door that is isolated from the outside by a partition wall and can be opened and closed in the front-rear direction, and a fitting that is guided by a rail and is slidable in the left-right direction. The present invention relates to a structure vibration suppression structure at the time of opening and closing a hinged door that suppresses the occurrence of vibrations in the furniture due to fluctuations.

住宅等の建物では、建物外部から建物内部の玄関ホールへ入る際、或いは玄関ホールから建物外部へ出る際に、玄関ドアを前後に開閉することに伴って玄関ホールの気圧が急激に変動することによって、玄関ホールに開閉可能に設けられた建具が振動し、ガタツキ音が生じたり建具に衝撃が加わるという問題がある。また、冷暖房効率等の観点から住宅の気密化が進む近年は玄関ホールの気密性も高まっていることに加えて、玄関ホールの冷たい空気が隣室に流れ込まないよう、その境界に設けられる建具は壁の開口を隙間なく塞ぐように設けられることが多いため、玄関ホールの気密性は一層高まっている。従って、玄関ドアの開閉時に玄関ホールに急激な気圧変動が生じやすく、上記建具の振動の問題がより顕著化している。 In buildings such as houses, when entering the entrance hall inside the building from the outside of the building, or when going out of the building from the entrance hall, the air pressure in the entrance hall fluctuates rapidly as the front door opens and closes. Therefore, there is a problem that the joinery provided in the entrance hall that can be opened and closed vibrates, and a rattling sound is generated or an impact is applied to the joinery. In addition, the airtightness of houses has been increasing in recent years from the viewpoint of cooling and heating efficiency, etc. In addition to the fact that the airtightness of the entrance hall has increased in recent years, the fixtures provided at the boundary of the entrance hall are walls so that the cold air of the entrance hall does not flow into the adjacent room In many cases, the airtightness of the entrance hall is further increased. Therefore, sudden pressure fluctuations are likely to occur in the entrance hall when the entrance door is opened and closed, and the problem of the vibration of the joinery becomes more prominent.

特に、建具が左右方向にスライドして開閉するいわゆる引き戸の場合、前後方向に回動して開閉するいわゆる開き戸のように床との間に隙間が設けられないため、玄関ホールは気密性がより高くなって玄関ドアの開閉時に気圧変動が生じやすい。更に、このような引き戸は、その下端部に回転可能に設けられた戸車が床に敷設されたレールに嵌合される構成とされ、戸車がスムーズに回転できるよう、戸車とレールとの間には若干の遊びが設けられるため、この遊び分のガタツキが生じやすい。 In particular, in the case of so-called sliding doors where the joinery slides in the left-right direction and opens and closes, there is no gap between the floor and the so-called swing door that rotates in the front-rear direction, so the entrance hall is more airtight. High pressure is likely to occur when opening and closing the front door. Furthermore, such a sliding door has a structure in which a doorwheel provided rotatably at the lower end of the sliding door is fitted to a rail laid on the floor so that the doorwheel can smoothly rotate. Since some play is provided, this play is likely to be loose.

このような問題を抑制する手段としては、ガタツキ防止用の部材を建具に取り付ける方法が従来提唱されている。図１２は、従来例に係るガタツキ防止具７０の構成を示す概略斜視図である（特許文献１参照）。このガタツキ防止具７０は、縦断面Ｌ字形状の取付部７１と、この取付部７１から湾曲して延出された一対の可撓片７２とから構成される。このガタツキ防止具７０は、その取付部７１が引き戸の上縁に取り付けられて可撓片７２が引き戸の側方へ膨出した状態となり、引き戸の上端部を鴨居溝に嵌合させた時に、可撓片７２が鴨居溝の側面に当接するようになっている。このような構成により、引き戸に生じた振動は可撓片７２の撓み変形によって吸収され、引き戸が鴨居溝に直接接触してガタツキ音が生じることがなく、また引き戸に衝撃が加わることもない。 As a means for suppressing such a problem, a method for attaching a rattle-preventing member to a fitting has been proposed. FIG. 12 is a schematic perspective view showing a configuration of a rattling prevention device 70 according to a conventional example (see Patent Document 1). The rattling prevention tool 70 includes a mounting portion 71 having an L-shaped vertical cross section and a pair of flexible pieces 72 that are curved and extended from the mounting portion 71. When the mounting portion 71 is attached to the upper edge of the sliding door and the flexible piece 72 bulges to the side of the sliding door and the upper end portion of the sliding door is fitted into the duck groove, The flexible piece 72 comes into contact with the side surface of the Kamoi groove. With such a configuration, the vibration generated in the sliding door is absorbed by the bending deformation of the flexible piece 72, and the sliding door does not come into direct contact with the duck groove and no rattling noise is generated, and no impact is applied to the sliding door.

また、上記問題を抑制する他の手段として、玄関ドアにいわゆるドアクローザを取り付ける方法も従来提唱されている（特許文献２参照）。このドアクローザは、油圧等を利用して扉の閉止速度を減速させることにより、扉が閉まる瞬間の衝撃や音を緩和するための装置である。このドアクローザを玄関ドアに取り付ければ、玄関ドアがゆっくりとした速度で閉まるので、玄関ホールの気圧が急激に変動することがない。従って、玄関ドアの閉止時に建具が振動するのを抑制することができる。 Moreover, the method of attaching what is called a door closer to the entrance door as another means to suppress the said problem is proposed conventionally (refer patent document 2). This door closer is a device for reducing the impact and sound at the moment when the door is closed by reducing the door closing speed using hydraulic pressure or the like. If this door closer is attached to the entrance door, the entrance door closes at a slow speed, so that the air pressure in the entrance hall does not fluctuate rapidly. Therefore, it is possible to prevent the joinery from vibrating when the entrance door is closed.

しかし、ガタツキ防止具７０を建具に取り付ける構造では、建具の数だけガタツキ防止具７０を用意してそれぞれ取付作業を行う必要があり、コストアップにつながるとともに取付作業が煩雑化するという問題がある。 However, in the structure in which the rattle prevention tool 70 is attached to the joinery, it is necessary to prepare the rattle prevention tools 70 as many as the number of the joinery and perform the attachment work respectively. This causes a problem that the cost increases and the attachment work becomes complicated.

また、ドアクローザを玄関ドアに取り付ける構造では、ドアクローザが果たす本来的な役割はドアが閉まる瞬間の衝撃や音を緩和することであるため、玄関ホールの気圧変動を抑制して建具の振動を防止するという効果は十分に得られないという問題がある。他方、玄関ホールの気圧変動を十分に抑制できるよう、玄関ドアの閉止速度が極低速になるようにドアクローザを設定した場合、玄関ドアが閉じるまでの時間が非常に長くなって使い勝手が悪くなるという問題がある。また、ドアクローザによれば、玄関ドアが閉じる瞬間に生じる玄関ホールの気圧変動は抑制できるものの、玄関ドアが開く瞬間に生じる玄関ホールの気圧変動は抑制することができないという問題もある。更に、ドアクローザは一般的に油圧式であって衝撃緩和効果が温度依存するため、ドアの閉止速度を一定に保つためには、季節ごとにドアクローザを調整しなければならないという問題もある。 In addition, in the structure where the door closer is attached to the entrance door, the primary role played by the door closer is to mitigate the impact and sound at the moment when the door closes. There is a problem that the effect cannot be sufficiently obtained. On the other hand, if the door closer is set so that the closing speed of the entrance door is extremely low so that fluctuations in the air pressure in the entrance hall can be sufficiently suppressed, the time until the entrance door closes becomes very long and the usability becomes poor. There's a problem. Moreover, according to the door closer, although the fluctuation | variation of the atmospheric pressure of the entrance hall that occurs at the moment when the entrance door closes can be suppressed, there is also a problem that the fluctuation of the atmospheric pressure of the entrance hall that occurs at the moment when the entrance door opens cannot be suppressed. Furthermore, since the door closer is generally hydraulic and the impact mitigation effect depends on temperature, there is a problem that the door closer must be adjusted every season in order to keep the door closing speed constant.

本発明は、このような問題に鑑みてなされたものであり、玄関ドアが閉じる瞬間と開く瞬間に生じる玄関ホールの急激な気圧変動を、簡略な構成で十分に抑制することが可能な手段を提供する。 The present invention has been made in view of such a problem, and a means capable of sufficiently suppressing, with a simple configuration, sudden pressure fluctuations in the entrance hall that occur when the entrance door closes and opens. provide.

また、本発明に係る開き戸開閉時の建具振動抑制構造は、隔壁によって外部と隔絶され、前後方向に開閉可能な開き戸と、レールに案内されて左右方向にスライド移動可能な建具とを備えた閉鎖空間で、前記開き戸の開閉に伴う前記閉鎖空間の気圧変動によって前記建具に振動が生じるのを抑制する開き戸開閉時の建具振動抑制構造において、前記開き戸の開閉を操作するためのドアハンドルと、該ドアハンドルの動きに連動して前記閉鎖空間の内部と外部とを通気または隔絶する通気機構と、を備えるものである。 Moreover, the vibration control structure for opening and closing of the hinged door according to the present invention includes a hinged door that is isolated from the outside by a partition wall and that can be opened and closed in the front-rear direction, and a fitting that is guided by the rail and that can slide in the left-right direction. A door handle for operating the opening and closing of the hinged door in a door opening and closing vibration suppressing structure that suppresses the occurrence of vibration in the fitting due to pressure fluctuations in the closed space accompanying the opening and closing of the hinged door in the space; and And a ventilation mechanism that ventilates or isolates the inside and the outside of the closed space in conjunction with the movement of the door handle.

また、本発明に係る開き戸開閉時の建具振動抑制構造は、前記通気機構が、前記開き戸と前記隔壁との間に形成された隙間と、該隙間を封鎖または開放する隙間調節部材と、を備えるものである。 Further, in the fitting vibration suppression structure when opening and closing the hinged door according to the present invention, the ventilation mechanism includes a gap formed between the hinged door and the partition wall, and a gap adjusting member that blocks or opens the gap. Is.

また、本発明に係る開き戸開閉時の建具振動抑制構造は、前記通気機構が、前記開き戸に貫通形成された通気窓と、該通気窓を封鎖または開放する窓調節部材と、を備えるものである。 In addition, in the fitting vibration suppression structure when opening and closing the hinged door according to the present invention, the ventilation mechanism includes a ventilation window penetratingly formed in the hinged door, and a window adjusting member that blocks or opens the ventilation window. .

本発明に係る開き戸開閉時の建具振動抑制構造によれば、開き戸が閉じた状態または開いた状態であって、閉鎖空間の内部と外部の気圧が等しい時は、気圧変動抑制弁が通気ダクトの内部空洞を閉鎖しており、通気ダクトの他端が接続された隣室等の気密性や防音性が確保される。一方、開き戸の開閉動作が開始されて閉鎖空間の内部と外部で瞬間的な気圧差が生じた時は、気圧変動抑制弁が通気ダクトの内部空洞を開放することにより、閉鎖空間の内部と外部の気圧が等しくなる。これにより、開き戸の開閉時に閉鎖空間に急激な気圧変動が生じることが抑制され、建具が振動してガタツキ音が生じたり衝撃が加わることを防止することができる。 According to the fixture vibration suppression structure at the time of opening and closing the hinged door according to the present invention, when the hinged door is in a closed state or in an opened state and the atmospheric pressure inside and outside the closed space is equal, the atmospheric pressure fluctuation suppression valve is connected to the ventilation duct. The internal cavity is closed, and the airtightness and soundproofing of the adjacent room to which the other end of the ventilation duct is connected are ensured. On the other hand, when the opening / closing operation of the hinged door is started and an instantaneous pressure difference occurs between the inside and outside of the enclosed space, the atmospheric pressure fluctuation control valve opens the inside cavity of the ventilation duct, so that the inside and outside of the enclosed space are The atmospheric pressure is equal. Accordingly, it is possible to suppress a sudden change in atmospheric pressure in the closed space when the hinged door is opened and closed, and it is possible to prevent the fitting from vibrating and causing a rattling sound or an impact.

また、本発明に係る開き戸開閉時の建具振動抑制構造によれば、開き戸が閉じた状態または開いた状態であって、開閉速度検知センサによって検知される開き戸の開閉速度が所定値に満たない間は、通気機構が閉鎖空間の内部と外部とを隔絶しており、閉鎖空間の気密性が確保される。一方、開き戸の開閉動作が開始されて開き戸の開閉速度が所定値を超えて大きくなると、通気機構が閉鎖空間の内部と外部を通気することにより、閉鎖空間の内部と外部の気圧が等しくなる。これにより、その後の開閉動作に伴って閉鎖空間に急激な気圧変動が生じることが抑制され、建具が振動してガタツキ音が生じたり衝撃が加わることを防止することができる。 Further, according to the joinery vibration suppressing structure at the time of opening and closing the hinged door according to the present invention, the hinged door is in a closed state or an opened state, and the opening and closing speed of the hinged door detected by the opening and closing speed detection sensor is less than a predetermined value. Since the ventilation mechanism isolates the inside and the outside of the closed space, the airtightness of the closed space is ensured. On the other hand, when the opening / closing operation of the hinged door is started and the opening / closing speed of the hinged door exceeds a predetermined value, the ventilation mechanism ventilates the inside and the outside of the closed space, so that the air pressure inside and outside the closed space becomes equal. Thereby, it is possible to suppress a sudden change in atmospheric pressure in the closed space with the subsequent opening / closing operation, and it is possible to prevent the fitting from vibrating and causing a rattling sound or an impact.

また、本発明に係る開き戸開閉時の建具振動抑制構造によれば、開き戸が閉じた状態または開いた状態であって、ドアハンドルが動作しない間は、通気機構が閉鎖空間の内部と外部とを隔絶しており、閉鎖空間の気密性が確保される。一方、開き戸の開閉動作が開始されてドアハンドルが動作すると、これに連動して通気機構が閉鎖空間の内部と外部を通気することにより、閉鎖空間の内部と外部の気圧が等しくなる。これにより、その後の開閉動作に伴って閉鎖空間に急激な気圧変動が生じることが抑制され、建具が振動してガタツキ音が生じたり衝撃が加わることを防止することができる。 Further, according to the joinery vibration suppressing structure at the time of opening and closing the hinged door according to the present invention, when the hinged door is closed or opened and the door handle is not operated, the ventilation mechanism connects the inside and the outside of the enclosed space. It is isolated and airtightness of the enclosed space is ensured. On the other hand, when the opening / closing operation of the hinged door is started and the door handle operates, the ventilation mechanism ventilates the inside and outside of the closed space in conjunction with this, so that the air pressure inside and outside the closed space becomes equal. Thereby, it is possible to suppress a sudden change in atmospheric pressure in the closed space with the subsequent opening / closing operation, and it is possible to prevent the fitting from vibrating and causing a rattling sound or an impact.

また、本発明に係る開き戸開閉時の建具振動抑制構造によれば、簡潔な構成で、且つ、周囲の環境条件等に影響を受けることもなく、開き戸の開閉時に生じる建具の振動を十分に抑制することができる。 Further, according to the structure for suppressing vibration of a door when opening and closing the hinged door according to the present invention, the vibration of the door that is generated when opening and closing the door is sufficiently suppressed with a simple configuration and without being affected by surrounding environmental conditions. can do.

まず、本発明の第１実施例に係る開き戸開閉時の建具振動抑制構造について図面に基づいて説明する。図１は、第１実施例に係る開き戸開閉時の建具振動抑制構造１（以下、単に「建具振動抑制構造」と略す。）を示す概略縦断面図である。建具振動抑制構造１は、住宅２の玄関ホール３と隣室４との間を連通する通気ダクト５と、該通気ダクト５の内部に設けられて玄関ホール３の内部の気圧変動を抑制する気圧変動抑制弁６と、を備えるものである。 First, a joinery vibration suppressing structure when opening and closing a hinged door according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view showing a joinery vibration suppressing structure 1 (hereinafter simply referred to as a “jointing tool vibration suppressing structure”) when opening and closing the hinged door according to the first embodiment. The joinery vibration suppression structure 1 includes a ventilation duct 5 that communicates between the entrance hall 3 of the house 2 and the adjacent room 4, and an atmospheric pressure fluctuation that is provided inside the ventilation duct 5 and suppresses an atmospheric pressure fluctuation inside the entrance hall 3. And a suppression valve 6.

図２は、本実施例に係る玄関ホール３を屋内側から見た概略斜視図である。玄関ホール３は、隔壁としての床７や天井８や壁９によって包囲されることで屋外１０と隔絶された閉鎖空間であって、屋外１０に面する壁９に開き戸１１が開閉可能に設けられる一方、図１に示す隣室４に面する壁９には引き戸（建具）１２が開閉可能に設けられている。尚、図２には示していないが、紙面手前側にも隔壁としての壁９が設けられている。 FIG. 2 is a schematic perspective view of the entrance hall 3 according to the present embodiment as viewed from the indoor side. The entrance hall 3 is a closed space that is isolated from the outdoor 10 by being surrounded by a floor 7, a ceiling 8, or a wall 9 as a partition wall, and a hinged door 11 is provided on the wall 9 facing the outdoor 10 so that it can be opened and closed. On the other hand, a sliding door (joint) 12 is provided on the wall 9 facing the adjacent room 4 shown in FIG. Although not shown in FIG. 2, a wall 9 as a partition wall is also provided on the front side of the sheet.

開き戸１１は、玄関ホール３と屋外１０との間を行き来するための玄関ドアである。ここで、図３は、開き戸１１を玄関ホール３側から見た概略正面図である。開き戸１１は、採光用窓１３が設けられた戸板１４の表裏両面に開閉操作用の把手１５をそれぞれ取り付けることで構成される。このように構成される開き戸１１は、屋外１０に面する壁９に形成された開口１６を塞ぐように配置され、把手１５と逆側の端部が蝶番１７を介して壁９に固定されるとともに、その上部には閉止速度を調整可能な従来公知のドアクローザ１８が取り付けられている。これにより開き戸１１は、蝶番１７を支点として回動することで前後方向に開閉可能に、且つ、ドアクローザ１８を調整することで閉止時の衝撃や音を緩和可能になっている。尚、開き戸１１の開き方向は、図２に示すように屋外１０側に向かって開く構成以外に、玄関ホール３側に向かって開く構成や、屋外１０側と玄関ホール３側の両方に向かって開く構成とすることも可能である。また、図に詳細は示さないが、開き戸１１は、２枚の戸板がそれぞれ前後方向に開閉するいわゆる両開きドアとして構成したり、両開きドアの中でも２枚の戸板の横幅が大小異なるいわゆる親子ドアとして構成することも可能である。 The hinged door 11 is an entrance door for going back and forth between the entrance hall 3 and the outdoor 10. Here, FIG. 3 is a schematic front view of the hinged door 11 as seen from the entrance hall 3 side. The hinged door 11 is configured by attaching handles 15 for opening and closing to both the front and back surfaces of a door plate 14 provided with a daylighting window 13. The hinged door 11 configured as described above is arranged so as to close the opening 16 formed in the wall 9 facing the outdoor 10, and the end opposite to the handle 15 is fixed to the wall 9 via a hinge 17. In addition, a conventionally known door closer 18 capable of adjusting the closing speed is attached to the upper portion thereof. As a result, the hinged door 11 can be opened and closed in the front-rear direction by rotating around the hinge 17, and the impact and sound at closing can be mitigated by adjusting the door closer 18. In addition, the opening direction of the hinged door 11 is not only the structure which opens toward the outdoor 10 side as shown in FIG. 2, but the structure which opens toward the entrance hall 3 side, or both the outdoor 10 side and the entrance hall 3 side. An open configuration is also possible. Although not shown in detail in the figure, the hinged door 11 is configured as a so-called double door in which two door plates open and close in the front-rear direction, or as a so-called parent-child door in which the width of the two door plates is different in size. It is also possible to configure.

引き戸１２は、玄関ホール３と隣室４との間を行き来するためのドアである。ここで、図４は、引き戸１２の下端部を拡大した概略縦断面図である。引き戸１２は、図２と図４に示すように、採光用窓１９が設けられた戸板１４と、この戸板１４の表裏両面にそれぞれ取り付けられた開閉操作用の把手２０と、戸板１４の下端部に回転自在に軸支された複数の戸車２１とを備えるものである。このように構成される引き戸１２は、床７に敷設された縦断面凹形状のレール２２に対して各戸車２１がそれぞれ嵌合され、各戸車２１がレール２２に沿って転動することによって、図２に矢印で示すように左右方向にスライドして開閉可能となっている。そして、このような引き戸１２の構造によれば、戸板１４の下端部と床７との間の隙間２３が狭く、床７との間に所定幅の隙間が設けられる開き戸１１と比較して玄関ホール３の気密性がより高まるので、開き戸１１の開閉によって玄関ホール３に気圧変動が生じやすい。更に、戸車２１をレール２２に嵌合させるに際しては、戸車２１がスムーズに転動できるよう、両者の間に若干の遊び２４が設けられるため、引き戸１２にはこの遊び２４分のガタツキが生じやすい。尚、本実施例では本発明に係る建具として引き戸１２を例に挙げて説明するが、これと同様に左右方向にスライドして床７との間の隙間が狭い構成を有するその他の建具、例えば窓やふすまや障子等であってもよい。 The sliding door 12 is a door for going back and forth between the entrance hall 3 and the adjacent room 4. Here, FIG. 4 is a schematic longitudinal sectional view in which the lower end portion of the sliding door 12 is enlarged. As shown in FIGS. 2 and 4, the sliding door 12 includes a door plate 14 provided with a daylighting window 19, a handle 20 for opening / closing operation respectively attached to both front and back surfaces of the door plate 14, and a lower end portion of the door plate 14. And a plurality of door wheels 21 that are rotatably supported by the shaft. In the sliding door 12 configured in this manner, each door wheel 21 is fitted to a rail 22 having a concave longitudinal section laid on the floor 7, and each door wheel 21 rolls along the rail 22. As shown by the arrows in FIG. 2, it can be opened and closed by sliding in the left-right direction. And, according to such a structure of the sliding door 12, the gap 23 between the lower end portion of the door plate 14 and the floor 7 is narrow, and the entrance is compared with the hinged door 11 in which a gap of a predetermined width is provided between the floor 7. Since the airtightness of the hall 3 is further increased, the atmospheric pressure fluctuation is likely to occur in the entrance hall 3 by opening and closing the hinged door 11. Further, when the door pulley 21 is fitted to the rail 22, a slight play 24 is provided between the two so that the door wheel 21 can smoothly roll, and thus the sliding door 12 is likely to be rattled for 24 minutes. . In this embodiment, the sliding door 12 will be described as an example of the joinery according to the present invention. However, other joinery having a configuration in which the gap between the floor 7 and the floor 7 is narrowed by sliding in the left-right direction in the same manner, for example, It may be a window, a bran or a shoji screen.

前記通気ダクト５は、玄関ホール３の内部と外部とを通気するためのものである。この通気ダクト５は、金属や樹脂等からなる管状部材であって、図１に示すように、天井裏２５に配設されて、その一端開口が玄関ホール３の天井８に形成された通気口に接続されるとともに、他端開口１６が隣室４の天井８に形成された通気口２６に接続されている。尚、本実施例では、通気ダクト５を天井裏２５に配設しているが、これに限られず、例えば壁９の中や床下２７に配設してもよい。また、玄関ホール３における通気ダクト５の一端側を接続する位置は、開き戸１１になるべく近い位置にした方が、開き戸１１の開閉によって玄関ホール３に生じる気圧変動の影響を引き戸１２が受けにくくなるので好適である。更に、通気ダクト５の他端側は玄関ホール３の外部に接続されていれば足り、隣室４まで延ばすことなく天井裏２５や床下２７に開口させた状態としてもよいし、屋外１０に接続してもよい。 The ventilation duct 5 is for ventilating the inside and outside of the entrance hall 3. The ventilation duct 5 is a tubular member made of metal, resin, or the like, and as shown in FIG. 1, the ventilation duct 5 is disposed on the ceiling back 25, and one end opening is formed in the ceiling 8 of the entrance hall 3. The other end opening 16 is connected to a vent hole 26 formed in the ceiling 8 of the adjacent chamber 4. In the present embodiment, the ventilation duct 5 is disposed in the ceiling back 25, but is not limited thereto, and may be disposed in the wall 9 or under the floor 27, for example. In addition, the position where the one end side of the ventilation duct 5 in the entrance hall 3 is connected as close as possible to the hinged door 11 makes it difficult for the sliding door 12 to be affected by atmospheric pressure fluctuations generated in the entrance hall 3 by opening and closing the hinged door 11. Therefore, it is preferable. Furthermore, it is sufficient that the other end of the ventilation duct 5 is connected to the outside of the entrance hall 3, and the vent duct 5 may be open to the ceiling 25 or the floor 27 without extending to the adjacent room 4, or connected to the outdoor 10. May be.

前記気圧変動抑制弁６は、開き戸１１の開閉によって玄関ホール３の内部と外部で気圧差が生じるのを抑制するためのものである。ここで、図５は、通気ダクト５における気圧変動抑制弁６の周辺を拡大した部分拡大縦断面図である。気圧変動抑制弁６は、通気ダクト５の内部空洞２８の形状に略合致する形状であって、その上端部２９が通気ダクト５の内部に固定されて、玄関ホール３の内部側と外部側の双方に向かってそれぞれ屈曲可能となっている。このような構成によれば、気圧変動抑制弁６を挟んだ両側の気圧が等しい時、すなわち開き戸１１が閉じた状態或いは開いた状態であって、玄関ホール３の内部と外部の気圧が等しい時は、気圧変動抑制弁６は外力を受けることなく自重によって鉛直な姿勢に保たれ、通気ダクト５の内部空洞２８を閉鎖している。これにより、隣室４の気密性を確保して冷暖房効率を良好に保つとともに、隣室４の防音性も確保することができる。 The atmospheric pressure fluctuation suppression valve 6 is for suppressing the occurrence of an atmospheric pressure difference between the inside and outside of the entrance hall 3 by opening and closing the hinged door 11. Here, FIG. 5 is a partially enlarged longitudinal sectional view in which the periphery of the atmospheric pressure fluctuation suppression valve 6 in the ventilation duct 5 is enlarged. The atmospheric pressure fluctuation suppression valve 6 has a shape that substantially matches the shape of the internal cavity 28 of the ventilation duct 5, and an upper end portion 29 of the pressure fluctuation suppression valve 6 is fixed to the inside of the ventilation duct 5. Each can be bent toward both sides. According to such a configuration, when the air pressures on both sides across the air pressure fluctuation suppression valve 6 are equal, that is, when the hinged door 11 is in a closed state or opened state, and the air pressure inside and outside the entrance hall 3 is equal. The atmospheric pressure fluctuation suppression valve 6 is maintained in a vertical posture by its own weight without receiving an external force, and closes the internal cavity 28 of the ventilation duct 5. Thereby, while ensuring the airtightness of the adjacent room 4 and maintaining favorable air-conditioning efficiency, the soundproofing property of the adjacent room 4 can also be ensured.

他方、気圧変動抑制弁６を挟んだ両側の気圧に差異が生じた時、すなわち開き戸１１が開閉されて玄関ホール３の内部の気圧が外部の気圧よりも瞬間的に高くまたは低くなった時は、高気圧側から低気圧側に向かって生じる空気の流れから力を受けることにより、図５に点線で示すように、気圧変動抑制弁６がその上端部２９を支点として屈曲し、通気ダクト５の内部空洞２８を開放する。これにより、開き戸１１を開いた瞬間に玄関ホール３の内部の気圧が外部の気圧より低くなると、気圧変動抑制弁６が玄関ホール３の内部側へ屈曲して、外部の空気が通気ダクト５を介して玄関ホール３の内部へ流入することにより、玄関ホール３の内部の気圧が外部の気圧と等しくなる。逆に、開き戸１１を閉じた瞬間に玄関ホール３の内部の気圧が外部の気圧より高くなると、気圧変動抑制弁６が玄関ホール３の外部側へ屈曲して、玄関ホール３の内部の空気が通気ダクト５を介して外部へ流出することにより、玄関ホール３の内部の気圧が外部の気圧と等しくなる。このようにして、玄関ホール３に急激な気圧変動が生じることを抑制することにより、前記引き戸１２等の建具が振動してガタツキ音が生じたり衝撃が加わることを防止することができる。尚、気圧変動抑制弁６の構造は、本実施例に限定されず、気圧差によって開閉する従来公知の弁構造を採用することができる。 On the other hand, when there is a difference between the pressures on both sides of the air pressure fluctuation suppression valve 6, that is, when the hinged door 11 is opened and closed, and the pressure inside the entrance hall 3 is instantaneously higher or lower than the outside pressure. By receiving a force from the air flow generated from the high pressure side to the low pressure side, as shown by a dotted line in FIG. 5, the atmospheric pressure fluctuation suppression valve 6 bends with its upper end portion 29 as a fulcrum, and the ventilation duct 5 The internal cavity 28 is opened. As a result, when the pressure inside the entrance hall 3 becomes lower than the outside pressure at the moment when the hinged door 11 is opened, the air pressure fluctuation suppression valve 6 bends toward the inside of the entrance hall 3 and the outside air passes through the ventilation duct 5. By flowing into the entrance hall 3 through the air pressure, the air pressure inside the entrance hall 3 becomes equal to the external air pressure. On the contrary, when the pressure inside the entrance hall 3 becomes higher than the outside pressure at the moment when the hinged door 11 is closed, the air pressure fluctuation suppression valve 6 bends to the outside of the entrance hall 3 and the air inside the entrance hall 3 is changed. By flowing out through the ventilation duct 5, the pressure inside the entrance hall 3 becomes equal to the pressure outside. In this way, it is possible to prevent rattling noises and impacts from being caused by vibrations of the fittings such as the sliding door 12 by suppressing the sudden fluctuation in atmospheric pressure in the entrance hall 3. In addition, the structure of the atmospheric pressure fluctuation suppression valve 6 is not limited to the present embodiment, and a conventionally known valve structure that opens and closes depending on an atmospheric pressure difference can be employed.

次に、本発明の第２実施例に係る建具振動抑制構造について図面に基づいて説明する。本実施例に係る建具振動抑制構造は、前記ドアクローザ１８に設けられて開き戸１１の開閉速度を検知する開閉速度検知センサ（不図示）と、開き戸１１の下端部に設けられて玄関ホール３の内部と外部を通気または隔絶する通気機構とを備えるものである。ここで、図６は本実施例に係る通気機構３０を示す図であり、図３における開き戸１１の下端部を拡大した部分拡大正面図である。尚、本実施例に係る玄関ホール３は、図２に示した第１実施例に係る玄関ホール３と比較して開き戸１１の周辺の構成だけが異なり、それ以外の引き戸１２等の構成は第１実施例と同じであるため、第１実施例と同じ符号を用い、ここでは詳細な説明を省略する。 Next, a joinery vibration suppressing structure according to a second embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppressing structure according to the present embodiment is provided in the door closer 18 to detect the opening / closing speed of the hinged door 11 (not shown), and provided in the lower end portion of the hinged door 11 to the interior of the entrance hall 3. And a ventilation mechanism for venting or isolating the outside. Here, FIG. 6 is a view showing the ventilation mechanism 30 according to the present embodiment, and is a partially enlarged front view in which the lower end portion of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

通気機構３０は、図６に示すように、戸板１４と床７との間の隙間３１を開放または封鎖する隙間調節部材３２が戸板１４の下端部から出没可能に設けられてなるものである。より詳細に説明すると、本実施例に係る開き戸１１の戸板１４は、その高さ寸法が、壁９に形成された開口１６の高さ寸法より若干小さく形成され、図６に示すように、その下端縁３３と床７との間に若干の隙間３１を空けるようにして、蝶番１７を介して壁９に固定される。そして、隙間調節部材３２は、この隙間３１よりも幅広に形成され、開閉速度検知センサからの信号に応じて戸板１４の下端部から出没することにより、隙間３１を開放または封鎖するよう制御されている。すなわち、開閉速度検知センサによって検知される開き戸１１の開閉速度が予め定めた所定値に達しない間は、図６（ａ）に示すように、隙間調節部材３２は戸板１４の下端部から突出して隙間３１を封鎖している。一方、開き戸１１の開閉速度が所定値を超えて大きくなると、図６（ｂ）に示すように、隙間調節部材３２は戸板１４の内部に没入して隙間３１を開放する。 As shown in FIG. 6, the ventilation mechanism 30 is provided with a gap adjusting member 32 that opens or closes the gap 31 between the door plate 14 and the floor 7 so as to be able to protrude from the lower end portion of the door plate 14. More specifically, the door plate 14 of the hinged door 11 according to the present embodiment is formed so that its height dimension is slightly smaller than the height dimension of the opening 16 formed in the wall 9, and as shown in FIG. It is fixed to the wall 9 via a hinge 17 so as to leave a slight gap 31 between the lower edge 33 and the floor 7. The gap adjusting member 32 is formed to be wider than the gap 31 and is controlled to open or block the gap 31 by projecting and descending from the lower end of the door plate 14 in response to a signal from the opening / closing speed detection sensor. Yes. That is, while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value, the gap adjustment member 32 protrudes from the lower end of the door plate 14 as shown in FIG. The gap 31 is blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the gap adjusting member 32 enters the inside of the door plate 14 and opens the gap 31 as shown in FIG.

このような構造によれば、開き戸１１が閉止した状態では、隙間調節部材３２によって隙間３１が封鎖されて玄関ホール３の気密性が保たれている。一方、閉止した状態の開き戸１１の把手１５を掴んで開き動作を開始すると、その開き速度が所定値に達した時に隙間調節部材３２が隙間３１を開放する。これにより、その後の開き動作に伴って玄関ホール３の内部の空気が外部へ流出しても、その一方で外部の空気が隙間３１を介して玄関ホール３の内部へ流入するので、玄関ホール３の内部の気圧が急激に低下することはない。従って、開き戸１１を開く瞬間に、前記引き戸１２等の建具が振動してガタツキ音が生じたり衝撃が加わることを未然に防止することができる。その後、開き戸１１が完全に開放されて停止した状態では、隙間調節部材３２は戸板１４の下端部から突出した状態となっている。 According to such a structure, when the hinged door 11 is closed, the gap 31 is blocked by the gap adjusting member 32 and the airtightness of the entrance hall 3 is maintained. On the other hand, when the opening operation is started by grasping the handle 15 of the hinged door 11 in the closed state, the gap adjusting member 32 opens the gap 31 when the opening speed reaches a predetermined value. Thereby, even if the air inside the entrance hall 3 flows out to the outside with the subsequent opening operation, the outside air flows into the entrance hall 3 through the gap 31, so that the entrance hall 3 The air pressure inside the water does not drop rapidly. Therefore, at the moment when the hinged door 11 is opened, it is possible to prevent the fittings such as the sliding door 12 from vibrating and causing rattling noises or impacts. Thereafter, in a state where the hinged door 11 is completely opened and stopped, the gap adjusting member 32 protrudes from the lower end portion of the door plate 14.

次に、開放された状態の開き戸１１の把手１５を掴んで閉じ動作を開始すると、その閉じ速度が所定値に達した時に隙間調節部材３２が隙間３１を開放する。これにより、その後の閉じ動作に伴って外部の空気が玄関ホール３の内部へ流入しても、その一方で玄関ホール３の内部の空気が隙間３１を介して外部へ流出するので、玄関ホール３の内部の気圧が急激に上昇することはない。従って、開き戸１１を閉じる瞬間に、前記引き戸１２等の建具が振動してガタツキ音が生じたり衝撃が加わることを未然に防止することができる。その後、開き戸１１が再び閉止状態になると、隙間調節部材３２によって隙間３１が封鎖されて玄関ホール３は気密状態になる。 Next, when the closing operation is started by grasping the handle 15 of the opened door 11 in the opened state, the gap adjusting member 32 opens the gap 31 when the closing speed reaches a predetermined value. Thereby, even if outside air flows into the entrance hall 3 with the subsequent closing operation, the inside air of the entrance hall 3 flows out to the outside through the gap 31. The air pressure inside the water does not rise rapidly. Therefore, at the moment when the hinged door 11 is closed, it is possible to prevent the fittings such as the sliding door 12 from vibrating and generating a rattling sound or an impact. After that, when the hinged door 11 is closed again, the gap 31 is blocked by the gap adjusting member 32 and the entrance hall 3 becomes airtight.

尚、本実施例では戸板１４の下端縁３３と床７との間に隙間３１を形成し、隙間調節部材３２が戸板１４の下端部から出没する構成としたが、これに代えて、戸板１４の上端縁と壁９との間に隙間（不図示）を形成し、隙間調節部材３２が戸板１４の上端部から出没する構成としてもよい。更に、本実施例では隙間調節部材３２を戸板１４から出没させたが、これに代えて、隙間調節部材３２を床７や壁９から出没させてもよい。 In this embodiment, the gap 31 is formed between the lower edge 33 of the door plate 14 and the floor 7, and the gap adjustment member 32 protrudes from the lower end of the door plate 14. It is good also as a structure which forms a clearance gap (not shown) between the upper end edge of this, and the wall 9, and the clearance gap adjustment member 32 protrudes and protrudes from the upper end part of the doorplate 14. FIG. Furthermore, in the present embodiment, the gap adjusting member 32 is protruded from the door plate 14, but the gap adjusting member 32 may be protruded from the floor 7 or the wall 9 instead.

また、本実施例では開閉速度検知センサをドアクローザ１８に設けたが、開き戸１１の開閉速度を検知可能な場所であれば、戸板１４や壁９に設けてもよい。更に、本実施例では開き戸１１の開閉動作に電気的に連動するように通気機構３０を動作制御したが、これに代えて、開き戸１１の開閉動作に機械的に連動するように通気機構３０を動作制御してもよい。すなわち、図に詳細は示さないが、引き戸１２に開閉操作用のドアノブやドアハンドルを設け、これらを掴んで廻すと、従来公知のクランク機構等を介して前記隙間調節部材３２が連動するように構成することも可能である。また、本実施例では通気機構３０の動作制御を行うためのトリガとして開き戸１１の開閉速度を用いたが、これに代えて、例えば開き戸１１の周辺における人の存否を用いることも可能である。すなわち、図に詳細は示さないが、開き戸１１の玄関ホール３側と屋外１０側に、従来公知の熱センサや赤外線センサ等によって人の存否を検知する人検知センサをそれぞれ設置し、人の存在を検知している間は、隙間調節部材３２を戸板１４に没入させて隙間３１を開放する一方、人の存在を検知しなくなると、隙間調節部材３２を戸板１４から突出させて隙間３１を封鎖するように構成することも可能である。また、通気機構３０を開閉不能にロックするロック機構を設け、これを開き戸１１自体のロック機構に連動させることにより、開き戸１１が開閉不能にロックされた場合には通気機構３０も開閉不能にロックするようにすれば、防犯上の観点から好適である。 In this embodiment, the opening / closing speed detection sensor is provided in the door closer 18, but it may be provided in the door plate 14 or the wall 9 as long as the opening / closing speed of the hinged door 11 can be detected. Further, in this embodiment, the ventilation mechanism 30 is controlled so as to be electrically interlocked with the opening / closing operation of the hinged door 11, but instead, the ventilation mechanism 30 is mechanically interlocked with the opening / closing operation of the hinged door 11. Operation control may be performed. That is, although not shown in detail in the figure, when the sliding door 12 is provided with a door knob and a door handle for opening and closing, and when these are grasped and turned, the gap adjusting member 32 is interlocked via a conventionally known crank mechanism or the like. It is also possible to configure. Further, in the present embodiment, the opening / closing speed of the hinged door 11 is used as a trigger for controlling the operation of the ventilation mechanism 30, but it is also possible to use, for example, the presence or absence of a person around the hinged door 11. That is, although details are not shown in the figure, human detection sensors for detecting the presence or absence of humans are installed on the entrance hall 3 side and the outdoor 10 side of the hinged door 11 by means of conventionally known thermal sensors, infrared sensors, etc. While detecting the gap, the gap adjusting member 32 is immersed in the door plate 14 to open the gap 31. When the presence of a person is not detected, the gap adjusting member 32 protrudes from the door plate 14 to block the gap 31. It is also possible to configure so as to. In addition, by providing a lock mechanism that locks the ventilation mechanism 30 so that it cannot be opened and closed, and interlocking this with the locking mechanism of the hinged door 11 itself, when the hinged door 11 is locked so that it cannot be opened and closed, the ventilation mechanism 30 is also locked so that it cannot be opened and closed. This is preferable from the viewpoint of crime prevention.

次に、本発明の第３実施例に係る建具振動抑制構造について図面に基づいて説明する。本実施例に係る建具振動抑制構造は、前記ドアクローザ１８に設けられて開き戸１１の開閉速度を検知する開閉速度検知センサ（不図示）と、開き戸１１の側端部に設けられて玄関ホール３の内部と外部を通気または隔絶する通気機構とを備えるものである。ここで、図７は本実施例に係る通気機構４０を示す図であり、図３における開き戸１１の右側端部を拡大した部分拡大正面図である。尚、本実施例に係る玄関ホール３は、図２に示した第１実施例に係る玄関ホール３と比較して開き戸１１の周辺の構成だけが異なり、それ以外の引き戸１２等の構成は第１実施例と同じであるため、第１実施例と同じ符号を用い、ここでは詳細な説明を省略する。 Next, a joinery vibration suppressing structure according to a third embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppression structure according to the present embodiment is provided in the door closer 18 to detect an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the hinged door 11, and is provided at the side end of the hinged door 11 to A ventilation mechanism that ventilates or isolates the inside and the outside is provided. Here, FIG. 7 is a view showing the ventilation mechanism 40 according to the present embodiment, and is a partially enlarged front view in which the right end portion of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

通気機構４０は、戸板１４と壁９との間の隙間４１を開放または封鎖する隙間調節部材４２が戸板１４の側端部から出没可能に設けられてなるものである。より詳細に説明すると、本実施例に係る開き戸１１の戸板１４は、その幅寸法が、壁９に形成された開口１６の幅寸法より若干小さく形成され、図７に示すように、向かって右側端縁４３と壁９との間に若干の隙間４１を空けるようにして、蝶番１７を介して壁９に固定される。そして、隙間調節部材４２は、この隙間４１よりも幅広に形成され、開閉速度検知センサからの信号に応じて戸板１４の右側端部から出没することにより、隙間４１を開放または封鎖するよう制御されている。すなわち、開閉速度検知センサによって検知される開き戸１１の開閉速度が予め定めた所定値に達しない間は、図７（ａ）に示すように、隙間調節部材４２は戸板１４の右側端部から突出して隙間４１を封鎖している。一方、開き戸１１の開閉速度が所定値を超えて大きくなると、図７（ｂ）に示すように、隙間調節部材４２は戸板１４の内部に没入して隙間４１を開放する。ここで、このような構造が奏する作用効果については第２実施例と同様であるため、ここでは説明を省略する。 The ventilation mechanism 40 is provided with a gap adjusting member 42 that opens or closes the gap 41 between the door plate 14 and the wall 9 so as to be able to protrude from the side end portion of the door plate 14. More specifically, the door plate 14 of the hinged door 11 according to the present embodiment has a width dimension slightly smaller than the width dimension of the opening 16 formed in the wall 9, and as shown in FIG. It is fixed to the wall 9 via a hinge 17 so as to leave a slight gap 41 between the edge 43 and the wall 9. The gap adjusting member 42 is formed wider than the gap 41, and is controlled to open or block the gap 41 by protruding from the right end of the door plate 14 according to a signal from the opening / closing speed detection sensor. ing. That is, while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value, the gap adjustment member 42 protrudes from the right end of the door plate 14 as shown in FIG. The gap 41 is blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the gap adjusting member 42 is immersed in the door plate 14 and opens the gap 41 as shown in FIG. Here, since the effect which such a structure has is the same as that of the second embodiment, the description thereof is omitted here.

尚、本実施例では戸板１４の右側端縁４３と壁９との間に隙間４１を形成し、隙間調節部材４２が戸板１４の右側端部から出没する構成としたが、これに代えて、戸板１４の左側端縁と壁９との間に隙間（不図示）を形成し、隙間調節部材４２が戸板１４の左側端部から出没する構成としてもよい。更に、本実施例では隙間調節部材４２を戸板１４から出没させたが、これに代えて、隙間調節部材４２を壁９から出没させてもよい。また、開閉速度検知センサの設置位置が戸板１４や壁９でもよい点、通気機構４０を開き戸１１の開閉動作に機械的に連動させてもよい点、通気機構４０の動作制御を行うためのトリガとして人検知センサを設置してもよい点、及び通気機構４０を開閉不能にロックするロック機構を設けて開き戸１１自体のロック機構に連動させれば防犯上好適である点、については第２実施例と同様である。 In the present embodiment, the gap 41 is formed between the right edge 43 of the door plate 14 and the wall 9, and the gap adjusting member 42 protrudes and protrudes from the right edge of the door plate 14, but instead, A gap (not shown) may be formed between the left edge of the door plate 14 and the wall 9, and the gap adjustment member 42 may protrude from the left edge of the door plate 14. Further, in the present embodiment, the gap adjusting member 42 is protruded from the door plate 14, but the gap adjusting member 42 may be protruded from the wall 9 instead. In addition, the installation position of the opening / closing speed detection sensor may be the door plate 14 or the wall 9, the ventilation mechanism 40 may be mechanically linked to the opening / closing operation of the opening door 11, and a trigger for controlling the operation of the ventilation mechanism 40. As for the point that a human detection sensor may be installed as well as that it is suitable for crime prevention if a lock mechanism that locks the ventilation mechanism 40 so that it cannot be opened and closed is interlocked with the lock mechanism of the hinged door 11 itself, Similar to the example.

次に、本発明の第４実施例に係る建具振動抑制構造について図面に基づいて説明する。本実施例に係る建具振動抑制構造は、玄関ホール３の内部と外部を通気または隔絶する通気機構を備えるものである。尚、本実施例に係る玄関ホール３は、図２に示した第１実施例に係る玄関ホール３と比較して開き戸１１の周辺の構成だけが異なり、それ以外の引き戸１２等の構成は第１実施例と同じであるため、第１実施例と同じ符号を用い、ここでは詳細な説明を省略する。 Next, a joinery vibration suppressing structure according to a fourth embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppressing structure according to the present embodiment includes a ventilation mechanism that ventilates or isolates the inside and outside of the entrance hall 3. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

ここで、図８と図９は本実施例に係る通気機構５０を示す図である。通気機構５０は、横幅が大きく開き戸として構成された親扉５１と、横幅が小さく引き戸として構成された子扉５２と、親扉の開閉速度を検知する開閉速度検知センサ（不図示）、とを具備している。親扉５１は、その幅方向一端部が蝶番５３を介して壁９ａに固定され、この蝶番５３を支点として回動することで前後方向に開閉可能となっている。一方、子扉５２は、床７に敷設されたレール５４に沿ってスライド移動可能に設けられ、開閉速度検知センサからの信号に応じて、壁９ｂに設けられた戸袋５５から出没するよう制御されている。すなわち、開閉速度検知センサによって検知される親扉５１の開閉速度が予め定めた所定値に達しない間は、子扉５２は戸袋５５から突出している。一方、親扉５１の開閉速度が所定値を超えて大きくなると、子扉５２はスライド移動して戸袋５５に収容される。 Here, FIGS. 8 and 9 are views showing the ventilation mechanism 50 according to the present embodiment. The ventilation mechanism 50 includes a main door 51 having a large width and configured as an open door, a child door 52 having a small width and configured as a sliding door, and an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the main door. It has. One end in the width direction of the main door 51 is fixed to the wall 9a via a hinge 53, and can be opened and closed in the front-rear direction by rotating around the hinge 53 as a fulcrum. On the other hand, the child door 52 is provided so as to be slidable along a rail 54 laid on the floor 7, and is controlled so as to appear and disappear from a door pocket 55 provided on the wall 9b in response to a signal from the opening / closing speed detection sensor. ing. That is, the child door 52 protrudes from the door pocket 55 while the opening / closing speed of the main door 51 detected by the opening / closing speed detection sensor does not reach a predetermined value. On the other hand, when the opening / closing speed of the main door 51 exceeds a predetermined value, the sub door 52 slides and is accommodated in the door pocket 55.

このように構成される通気機構５０によれば、図８（ａ）に示すように親扉５１が完全に開いた状態では、子扉５２は戸袋５５から完全に突出した状態となっている。この状態から親扉５１の閉じ動作を開始すると、その閉じ速度が所定値に達した時に、図８（ｂ）に示すように子扉５２が戸袋５５の方向へスライド移動を開始し、親扉５１と壁９ｂとの間の隙間５６を一部開放する。これにより、その後の親扉５１の閉じ動作に伴って外部の空気が玄関ホール３の内部へ流入しても、その一方で玄関ホール３の内部の空気が隙間５６を介して外部へ流出するので、玄関ホール３の内部の気圧が急激に上昇することはない。従って、親扉５１を閉じる瞬間に、前記引き戸１２等の建具が振動してガタツキ音が生じたり衝撃が加わることを未然に防止することができる。その後、図９（ａ）に示すように親扉５１が完全に閉止状態になると、子扉５２が親扉５１側へスライド移動を開始し、図９（ｂ）に示すように子扉５２が隙間５６を完全に封鎖することにより、玄関ホール３は気密状態になる。 According to the ventilation mechanism 50 configured as described above, as shown in FIG. 8A, when the main door 51 is completely opened, the child door 52 is completely protruded from the door pocket 55. When the closing operation of the main door 51 is started from this state, when the closing speed reaches a predetermined value, the child door 52 starts to slide in the direction of the door pocket 55 as shown in FIG. A part of the gap 56 between 51 and the wall 9b is opened. As a result, even if external air flows into the entrance hall 3 along with the subsequent closing operation of the main door 51, the air inside the entrance hall 3 flows out through the gap 56 to the outside. The air pressure inside the entrance hall 3 does not rise rapidly. Therefore, at the moment when the main door 51 is closed, it is possible to prevent the fittings such as the sliding door 12 from vibrating and causing rattling noises or impacts. Thereafter, when the main door 51 is completely closed as shown in FIG. 9A, the sub door 52 starts to slide toward the main door 51, and the sub door 52 is moved as shown in FIG. 9B. By completely closing the gap 56, the entrance hall 3 becomes airtight.

尚、本実施例では親扉５１の閉じ動作時について説明したが、親扉５１の開き動作時にも、親扉５１の開き速度が所定値に達した時に子扉５２を戸袋５５側へスライド移動させて隙間５６を一部開放することにより、閉じ動作時と同様の作用効果を得ることができる。また、通気機構５０を親扉５１の開閉動作に機械的に連動させてもよい点、通気機構５０の動作制御を行うためのトリガとして人検知センサを設置してもよい点、及び子扉５２を開閉不能にロックするロック機構を設けて親扉５１自体のロック機構に連動させれば防犯上好適である点、については第２実施例と同様である。 In this embodiment, the operation of closing the main door 51 has been described. However, even when the main door 51 is opened, the child door 52 is slid to the door pocket 55 side when the opening speed of the main door 51 reaches a predetermined value. Thus, by partially opening the gap 56, it is possible to obtain the same effect as that during the closing operation. In addition, the ventilation mechanism 50 may be mechanically interlocked with the opening / closing operation of the main door 51, the human detection sensor may be installed as a trigger for controlling the operation of the ventilation mechanism 50, and the child door 52. It is the same as in the second embodiment that a lock mechanism for locking the door to be opened and closed is suitable for crime prevention if the lock mechanism is interlocked with the lock mechanism of the main door 51 itself.

次に、本発明の第５実施例に係る建具振動抑制構造について図面に基づいて説明する。本実施例に係る建具振動抑制構造は、前記ドアクローザ１８に設けられて開き戸１１の開閉速度を検知する開閉速度検知センサ（不図示）と、開き戸１１の前記採光用窓１３に設けられて玄関ホール３の内部と外部を通気または隔絶する通気機構とを備えるものである。ここで、図１０は本実施例に係る通気機構６０を示す図であり、図３における開き戸１１の採光用窓１３を拡大した部分拡大正面図である。尚、本実施例に係る玄関ホール３は、図２に示した第１実施例に係る玄関ホール３と比較して開き戸１１の周辺の構成だけが異なり、それ以外の引き戸１２等の構成は第１実施例と同じであるため、第１実施例と同じ符号を用い、ここでは詳細な説明を省略する。 Next, a joinery vibration suppressing structure according to a fifth embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppression structure according to the present embodiment is provided in the door closer 18 and is provided in an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the hinged door 11, and in the daylighting window 13 of the hinged door 11. 3 is provided with a ventilation mechanism that ventilates or isolates the inside and the outside. Here, FIG. 10 is a view showing the ventilation mechanism 60 according to the present embodiment, and is a partially enlarged front view in which the daylighting window 13 of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

通気機構６０は、戸板１４に設けられた採光用窓１３を開閉可能に構成したものである。すなわち、この採光用窓１３は、戸板１４を貫通して形成された通気窓６１に対し、外部の光を採り込むための透明な窓ガラス（窓調節部材）６２が、戸板１４から出没して通気窓６１を封鎖または開放するように設けられている。すなわち、窓ガラス６２は、開閉速度検知センサによって検知される開き戸１１の開閉速度が予め定めた所定値に達しない間は、図１０（ａ）に示すように戸板１４から突出して通気窓６１を封鎖している。一方、開き戸１１の開閉速度が所定値を超えて大きくなると、図１０（ｂ）に示すように、窓ガラス６２が戸板１４の内部に没入して通気窓６１を開放する。ここで、このような構造が奏する作用効果については第２実施例と同様であるため、ここでは説明を省略する。 The ventilation mechanism 60 is configured to be able to open and close the daylighting window 13 provided on the door plate 14. That is, in the daylighting window 13, a transparent window glass (window adjusting member) 62 for taking in external light from the ventilating window 61 formed through the doorboard 14 protrudes and appears from the doorboard 14. The ventilation window 61 is provided so as to be blocked or opened. That is, the window glass 62 protrudes from the door plate 14 as shown in FIG. 10 (a) and opens the ventilation window 61 while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value. Blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the window glass 62 immerses into the door plate 14 and opens the ventilation window 61 as shown in FIG. Here, since the effect which such a structure has is the same as that of the second embodiment, the description thereof is omitted here.

尚、戸板１４における通気窓６１の形成位置、個数、及び形状や、窓ガラス６２の開閉方式等は、適宜設計変更が可能である。例えば、窓ガラス６２の開閉方式を、図１１（ａ）に示すように蝶番６３を介した方式としたり、図１１（ｂ）に示すように屈曲可能なアーム部材６４を介した方式としてもよい。また、開閉速度検知センサの設置位置が戸板１４や壁９でもよい点、通気機構６０を開き戸１１の開閉動作に機械的に連動させてもよい点、通気機構６０の動作制御を行うためのトリガとして人検知センサを設置してもよい点、及び通気機構６０を開閉不能にロックするロック機構を設けて開き戸１１自体のロック機構に連動させれば防犯上好適である点、については第２実施例と同様である。更に、本実施例では引き戸１２の戸板１４に通気窓６１を形成したが、壁９や床７や天井８に通気窓６１を形成してもよい。この場合、通気窓６１を形成する位置は、開き戸１１になるべく近い位置にした方が、開き戸１１の開閉によって玄関ホール３に生じる気圧変動の影響を建具が受けにくくなるので好適である。 In addition, the formation position, the number, and the shape of the ventilation window 61 in the door plate 14, the opening / closing method of the window glass 62, and the like can be appropriately changed. For example, the opening / closing method of the window glass 62 may be a method using a hinge 63 as shown in FIG. 11 (a), or a method using a bendable arm member 64 as shown in FIG. 11 (b). . Further, the installation position of the opening / closing speed detection sensor may be the door plate 14 or the wall 9, the ventilation mechanism 60 may be mechanically linked to the opening / closing operation of the opening door 11, and a trigger for controlling the operation of the ventilation mechanism 60. As for the point that a human detection sensor may be installed as well as the fact that a locking mechanism that locks the ventilation mechanism 60 so that it cannot be opened and closed and interlocked with the locking mechanism of the hinged door 11 itself is suitable for crime prevention. Similar to the example. Furthermore, in the present embodiment, the ventilation window 61 is formed on the door plate 14 of the sliding door 12, but the ventilation window 61 may be formed on the wall 9, the floor 7, or the ceiling 8. In this case, it is preferable that the position where the ventilation window 61 is formed is as close as possible to the hinged door 11 because the fitting is less likely to be affected by atmospheric pressure fluctuations generated in the entrance hall 3 by opening and closing the hinged door 11.

尚、本発明に係る建具振動抑制構造は、隔壁によって外部と隔絶された空間であれば、住宅２の玄関ホール３だけでなく、例えば勝手口の空間や、屋内の閉鎖された空間に対しても適用することができる。また、本発明に係る建具振動構造は、住宅２内だけでなく、例えばオフィスビル等において外部と隔絶された空間にも適用することができる。また、通気ダクト５や通気機構３０，４０，５０，６０で玄関ホール３の内部と外部を通気することに代えて、開き戸１１の開閉等に連動してポンプ等を用いて玄関ホール３の内部の気圧を調整するようにしてもよい。 In addition, if the joinery vibration suppression structure according to the present invention is a space isolated from the outside by a partition wall, not only the entrance hall 3 of the house 2 but also, for example, an open space or an indoor closed space Can also be applied. The joinery vibration structure according to the present invention can be applied not only in the house 2 but also in a space isolated from the outside, for example, in an office building. Further, instead of ventilating the inside and outside of the entrance hall 3 with the ventilation duct 5 and the ventilation mechanisms 30, 40, 50, 60, the interior of the entrance hall 3 is used by using a pump or the like in conjunction with opening / closing of the hinged door 11. The atmospheric pressure may be adjusted.

本発明に係る建具振動抑制構造は、上記各実施例を適宜組み合わせることも可能である。 The joinery vibration suppression structure according to the present invention can also be appropriately combined with the above embodiments.
