Description

【0001】
【発明の属する技術分野】
この発明は、建物の屋外出入り口に設置される扉であって、特に通風機能を付与した扉に関するものである。
【0002】
【従来の技術】
従来、扉に小窓あるいはスリット等の開口部を設け、この開口部を通風可能とするダンパーを設けた通風機能付扉が知られている(特開平11−200724号、同平11−200723号、同平11−200722号、同2000−8731号公報参照)。
【0003】
スライド可能な蓋部材で開口部を開閉可能とする場合、開口部を大きく形成すれば、充分な通風量が得られるものの、外部からの視線を遮断するのが困難となり、防犯上好ましくない。
一方、扉内部に通風路を設けて扉の表側と裏側における開口部の位置を変えた場合には、外部からの視線を遮断することは可能であるが、扉内部の通風路を流れる風量はごく僅かであり、充分な通風機能を得ることができない等の問題があった。
【0004】
このような通風機能付扉には、開口部の開閉が簡単に行い得ると共に、充分な通風量が確保でき、開口部を開放状態とした際には、外部からの視線を遮断できる等の機能が求められている。
【0005】
【発明が解決しようとする課題】
この発明の目的は、扉に比較的大きな通風用の開口部を形成するにも関わらず、外部からの視線を遮断し、防犯に適した通風機能付扉を提供することにある。
【0006】
【課題を解決するための手段】
本発明者等は、このような事情に鑑み鋭意検討を重ねた結果、扉に開口部を設けると共に、開口部を開閉可能な回転蓋部材を開口部を形成した位置に設け、該回転蓋部材は断面略扇形状を呈し、回転蓋部材は上下端部で且つ断面中心位置から偏倚した位置に設けた回転軸を扉に枢着して偏心回転可能とし、回転蓋部材の周面に回転軸の軸心を中心とした円弧状の封止面を形成し、該封止面の端部から回転軸にかけて平面状の整流面を形成し、回転蓋部材の回転軸にピニオンギヤを設け、該ピニオンギヤと咬合するラックをスライド自在として扉に設け、ラックの端部にはラックのスライド方向と傾斜するガイド孔を穿設し、ガイド孔には扉に設けた開閉操作部材の端部に設けた連結ピンを嵌合し、開閉操作部材を操作することによりガイド孔内に位置する連結ピンを移動してラックのスライド動作を行い、ラックと咬合するピニオンギヤを回転して回転蓋部材を偏心回転し、回転蓋部材の封止面を開口部縁に近接あるいは離間して開口部を開閉可能としたことによって、所期の目的を達成したものである。
【0007】
回転蓋部材は回転軸を端部に設けた断面略扇形状を呈し、回転蓋部材の周面に回転軸の軸心を中心とした円弧状の封止面を形成し、回転蓋部材を偏心回転して円弧状の封止面を開口部縁に近接あるいは離間して開口部を開閉可能としたものであるから、強固な回転蓋部材とすることができ、しかも回転蓋部材は断面略扇形状となる立体的な形状を呈しているので、扉にボリューム感のある印象を与えることができ、回転蓋部材が偏心回転する過程においても、外部からの視線を効果的に遮断することすることができる。
【0008】
回転蓋部材の回転機構としては、回転蓋部材の回転軸にピニオンギヤを設け、該ピニオンギヤと咬合するスライド自在なラックを扉に設け、ラックのスライド動作によりピニオンギヤが回転して回転蓋部材を偏心回転したものであるから、コンパクトな構成とすることができる。
【0009】
本発明通風機能付扉は、扉に開口部を設けると共に、開口部を開閉可能な回転蓋部材を開口部を形成した位置に設け、該回転蓋部材は断面略扇形状を呈し、回転蓋部材は上下端部で且つ断面中心位置から偏倚した位置に設けた回転軸を扉に枢着して偏心回転可能とし、回転蓋部材の周面に回転軸の軸心を中心とした円弧状の封止面を形成し、該封止面の端部から回転軸にかけて平面状の整流面を形成し、回転蓋部材の回転軸にピニオンギヤを設け、該ピニオンギヤと咬合するラックをスライド自在として扉に設け、ラックの端部にはラックのスライド方向と傾斜するガイド孔を穿設し、ガイド孔には扉に設けた開閉操作部材の端部に設けた連結ピンを嵌合し、開閉操作部材を操作することによりガイド孔内に位置する連結ピンを移動してラックのスライド動作を行い、ラックと咬合するピニオンギヤを回転して回転蓋部材を偏心回転し、回転蓋部材の封止面を開口部縁に近接あるいは離間して開口部を開閉可能としたものである。
【0010】
【作用】
この発明によれば、扉に設けた開口部を開閉可能とする回転蓋部材は偏心回転するよう扉に枢着し、偏心回転する回転蓋部材の周面を開口部縁に近接あるいは離間して開口部を開閉可能としているので、回転蓋部材を回転させる簡単な操作により開口部を開閉可能とすることができ、大きな開口部を形成するにも関わらず開口部の位置には常に回転蓋部材が配置されるので、回転蓋部材によって外部からの視線を効果的に遮断することができる。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態として実施例を図面に基づいて説明する。
図1ないし7は本発明通風機能付扉の実施例であり、図中1は扉を表わし、扉1は建物の屋外出入口等に設けられる。扉1が取付けられる部位には扉取付枠2が設けられ、扉取付枠2に扉1が蝶番21を介して水平回動自在に取付けられている。さらに、扉1には把手12が設けられており、把手12を操作して扉1が開閉可能となる。
【0012】
扉1の中央部には通風機構ユニットWが設けられており、通風機構ユニットWの周囲は上下横框13,14と左右縦框15,16によって囲われている。そして、通風機構ユニットWは扉1と一体構造となるように構成されている。なお、17は扉1に設けた格子体であり、格子体17が設けられた側が屋外側に面するように設置される。
通風機構はユニット化することにより、扉1への組み付けが簡単となり、メンテナンス作業を容易に実施することができる。また、他の種類の扉、例えば引戸等への適用も簡単に実施することができる。
通風機構ユニットWの周囲は、上枠31、下枠32、左枠33、右枠34により枠組された枠部3によって囲われており、上枠31と下枠32の間には所定の間隔を置いて縦桟材4が架設されている。そして、隣接する縦桟材4の間と両側に位置する縦桟材4と左枠33、右枠34の間には、通風可能な開口部5が形成されている。
【0013】
開口部5が形成された位置には、回転蓋部材6が配設されており、回転蓋部材6の上下端部に突出した回転軸61が上枠31と下枠32に枢支されている。回転蓋部材6は、その中心位置から偏倚した位置に設けられた回転軸61を中心とした偏心回転を行う。回転蓋部材6は内部中空状のアルミニウム製形材により形成された断面略扇状を呈し、回転蓋部材6の周面には回転軸61の軸心を中心とした円弧状の封止面62が形成されている。さらに、封止面62の端部から回転軸61にかけては、平面状の整流面63が形成されている。
【0014】
開口部5の縁となる縦桟材4の両側縁と左枠33、右枠34の開口部5側には、縁部材7が設けられており、縁部材7には封止面62と略同じ曲率を有する曲面部71が形成されている。よって、回転蓋部材6が偏心回転して封止面62と曲面部71が近接し、開口部5が閉鎖される。
【0015】
上側に突出する回転軸61にはピニオンギア8が設けられており、ピニオンギア8は上枠31内に突出した回転軸61の先端に固着されている。さらに、上枠31内に内装されたピニオンギア8は、上枠31内に嵌挿したラック9と咬合している。ラック9は上枠31内を長手方向に沿ってスライド自在であり、ラック9のスライド動作に連動してピニオンギア8が回転し、回転蓋部材6が回転軸61の軸心を中心として偏心回転する。
【0016】
ラック9の一端部と上枠31の一端部との間には、上枠31に固着した軸311に巻回したコイルスプリング10が配設されており、コイルスプリング10は回転蓋部材6が閉鎖状態となるようラック9を上枠31の一端部に向けて付勢している。ラック9の他端部にはラック9の移動方向と傾斜するガイド孔91が形成されており、ガイド孔91の両端部にはラック9の移動方向と直交する位置規制部911が形成されている。右枠34内には開閉操作部材11が内装されており、ラック9のガイド孔91には開閉操作部材11の一端部に設けた連結ピン111が嵌合している。開閉操作部材11の他端部に操作ノブ112が連結されており、操作ノブ112は右枠34の表面に配置されている。
【0017】
以上の構成から成る通風機構ユニットWの動作について説明する。
図1、図3、図4は開口部5を開放した状態であり、図2、図7は開口部5を閉鎖した状態である。開口部5を閉鎖している状態では、図2に示したとおり、封止面62と曲面部71が近接している。この閉鎖状態から開口部5を開放する場合、先ず操作ノブ112を開方向に移動すると、開閉操作部材11が上動し、先端に設けられた連結ピン111も同様に上動する。この時、連結ピン111はラック9に形成した傾斜状のガイド孔91と嵌合しているので、連結ピン111によりラック9を右枠34に向けてスライドさせる力が作用する。そしてラック9はコイルスプリング10の付勢力に抗して右枠34に向けてスライドし、ラック9と咬合するピニオンギア8が回転する。ピニオンギア8の回転により回転軸61を中心として、回転蓋部材6が偏心回転を開始する。
【0018】
さらに操作ノブ112を開方向に移動させると、連結ピン111はガイド孔91の端部に向けてさらに移動し、ラック9も右枠34に向けてスライドして、ピニオンギア8もさらに回転する。連結ピン111がガイド孔91の位置規制部911に到達すると、ラック9のスライドとピニオンギア8の回転が完了し、回転蓋部材6の偏心回転も完了する。即ち、図3に示したとおり、開口部5と回転蓋部材6の間には空間部が形成され、通風可能となる。なお、連結ピン111はガイド孔91の位置規制部911に嵌まり込み、コイルスプリング10のバネ力によって、ラック9が逆方向に押し戻されることはない。開口部5の開放状態において、外部から流入する空気は回転蓋部材6に形成した整流面63によって整流されて屋内側に流れ込むので、回転蓋部材6が障壁となって扉1に大きな風圧が加わるのを防止している。
【0019】
次に、開口部5の開放状態から閉鎖状態とする場合には、操作ノブ112を閉方向である下方に移動すると、連結ピン111がガイド孔91の位置規制部911から抜け出て、ガイド孔91内を下方に向けて移動する。この時ラック9には、連結ピン111の移動により左枠33に向けてスライドさせようとする力と、コイルスプリング10による付勢力が作用し、開放する場合よりも円滑にラック9をスライドさせることができ、ピニオンギア8に連結された回転蓋部材6を偏心回転することができる。連結ピン111は開放状態とは対向する位置に形成されたガイド孔91の位置規制部911に嵌まり込み、回転蓋部材6の偏心回転が終了する。開口部5の閉鎖状態においては、回転蓋部材6の封止面62と縁部材7の曲面部71が近接して開口部5が閉鎖され、通風が制限される。
【0020】
上記実施例において、縦長状の開口部5を設け、回転蓋部材6を上枠31と下枠32に枢支したが、横長状の開口部5として回転蓋部材6を左右枠33,34に枢支しても構わない。また、回転蓋部材6の封止面62と縁部材7の曲面部71との何れか一方に弾性部材を貼付して、閉鎖状態における密閉状態を高めることができる。また、回転蓋部材6は中空状の形材としたが、内部が充填されたものを使用して断熱性を高めることができる。回転蓋部材6の形状は特に限定されず、開口部5の縁に近接する封止面62を有するものであれば良い。開口部5並びに回転蓋部材6の大きさと数は実施例のものに限定されるものではない。さらに、防虫効果を高める目的で、扉1の屋外側には防虫網を配設すべきである。
【0021】
【発明の効果】
本発明通風機能付扉によれば、扉に設けた開口部を開閉可能な回転蓋部材が偏心回転するよう扉に枢着し、偏心回転する回転蓋部材を開口部に近接あるいは離間して開口部を開閉可能としたものであるから、回転蓋部材を開口部の位置で回転するだけで簡単に開口部の開閉操作を行うことができ、外部からの視線を効果的に遮断することができる。

[0017]
The operation of the ventilation mechanism unit W configured as above will be described.
1, 3, and 4 show a state in which the opening 5 is opened, and FIGS. 2 and 7 show a state in which the opening 5 is closed. In the state where the opening 5 is closed, the sealing surface 62 and the curved surface 71 are close to each other as shown in FIG. When opening the opening 5 from this closed state, when the operation knob 112 is first moved in the opening direction, the opening / closing operation member 11 is moved up, and the connecting pin 111 provided at the tip is also moved up. At this time, since the connecting pin 111 is fitted into the inclined guide hole 91 formed in the rack 9, a force for sliding the rack 9 toward the right frame 34 is applied by the connecting pin 111. The rack 9 slides toward the right frame 34 against the urging force of the coil spring 10, and the pinion gear 8 that meshes with the rack 9 rotates. The rotation lid member 6 starts to rotate eccentrically around the rotation shaft 61 by the rotation of the pinion gear 8.
[0018]
When the operation knob 112 is further moved in the opening direction, the connecting pin 111 further moves toward the end of the guide hole 91, the rack 9 slides toward the right frame 34, and the pinion gear 8 further rotates. When the connecting pin 111 reaches the position restricting portion 911 of the guide hole 91, the sliding of the rack 9 and the rotation of the pinion gear 8 are completed, and the eccentric rotation of the rotating lid member 6 is also completed. That is, as shown in FIG. 3, a space is formed between the opening 5 and the rotary lid member 6 so that ventilation is possible. The connecting pin 111 is fitted into the position restricting portion 911 of the guide hole 91, and the rack 9 is not pushed back in the reverse direction by the spring force of the coil spring 10. In the open state of the opening 5, the air flowing in from the outside is rectified by the rectifying surface 63 formed on the rotary lid member 6 and flows into the indoor side, so that the rotary lid member 6 acts as a barrier and a large wind pressure is applied to the door 1. Is preventing.
[0019]
Next, when the opening 5 is changed from the open state to the closed state, when the operation knob 112 is moved downward in the closing direction, the connecting pin 111 comes out of the position restricting portion 911 of the guide hole 91, and the guide hole 91. Move inward downward. At this time, the rack 9 is slid more smoothly than the case where the rack 9 is released due to the force of the connecting pin 111 moving to slide toward the left frame 33 and the biasing force of the coil spring 10. The rotary lid member 6 connected to the pinion gear 8 can be eccentrically rotated. The connecting pin 111 is fitted into the position restricting portion 911 of the guide hole 91 formed at a position opposite to the open state, and the eccentric rotation of the rotary lid member 6 is completed. In the closed state of the opening 5, the sealing surface 62 of the rotary lid member 6 and the curved surface 71 of the edge member 7 come close to each other to close the opening 5 and restrict ventilation.
[0020]
In the above embodiment, the vertically long opening 5 is provided, and the rotating lid member 6 is pivotally supported by the upper frame 31 and the lower frame 32. However, the rotating lid member 6 is formed in the left and right frames 33 and 34 as the horizontally elongated opening 5. You can pivot. Moreover, an elastic member can be affixed on either the sealing surface 62 of the rotary lid member 6 or the curved surface portion 71 of the edge member 7 to enhance the sealed state in the closed state. Moreover, although the rotary cover member 6 was made into the hollow shape material, it can improve heat insulation using the thing with which the inside was filled.
