Description
この発明は、主として住宅やマンション等の建物の玄関ドアとして用いられる通風機能を有するドアに関する。 The present invention relates to a door having a ventilation function mainly used as an entrance door of a building such as a house or an apartment.
従来より、例えば特許文献１や特許文献２にも開示されているように、住宅やマンション等の建物における玄関ドアとして、通風機能を有するものが各種提案されている。 Conventionally, as disclosed in, for example, Patent Document 1 and Patent Document 2, various door doors having a ventilation function have been proposed as entrance doors in buildings such as houses and apartments.
特許文献１に記載の玄関ドアは、ドア本体に屋内外を連通する通風用開口部が形成され、通風用開口部の屋外側及び屋内側を覆うカバー部材が設けられ、屋外側のカバー部材の両側端部付近には、風を取り込む隙間が形成されている。特許文献２に記載の玄関ドアは、ドア本体に屋内外を連通する通風用開口部が形成され、通風用開口部の屋外側を覆うカバー部材が設けられ、通風用開口部の屋内側に小扉が設けられ、カバー部材には、風を取り込む通風孔が形成されている。 The entrance door described in Patent Document 1 is provided with a ventilation opening that communicates indoors and outdoors with the door body, a cover member that covers the outdoor side and the indoor side of the ventilation opening is provided, A gap for taking in wind is formed in the vicinity of both end portions. The entrance door described in Patent Document 2 is provided with a ventilation opening in the door body that communicates indoors and outdoors, a cover member that covers the outdoor side of the ventilation opening is provided, and a small opening on the indoor side of the ventilation opening. A door is provided, and a ventilation hole for taking in air is formed in the cover member.
一般に、建物周辺の風は、建物外壁に沿って横方向に流れる傾向にあり、玄関ドア付近ではドア本体の屋外側表面に沿って横方向に流れることが多い。ところが、上記の玄関ドアにおいては、ドア本体の屋外側表面に対して向ってくるように流れる風については、比較的スムーズに取り込んで通風用開口部へ流れ込ませることができるが、ドア本体の屋外側表面に沿って横方向に流れる風については、スムーズに取り込んで通風用開口部へ流れ込ませることができず、通風効率が悪いといった不具合があった。 Generally, the wind around the building tends to flow in the lateral direction along the outer wall of the building, and often flows in the lateral direction along the outdoor side surface of the door body near the entrance door. However, in the above entrance door, the wind that flows toward the outdoor surface of the door body can be taken relatively smoothly and flow into the ventilation opening. The wind flowing in the lateral direction along the outer surface cannot be smoothly taken in and flowed into the ventilation opening, resulting in poor ventilation efficiency.
また、玄関ドア自体を屋外側へ僅かに開け放して、この状態を金具等で保持することで、通風を確保することも一般的に行われている。この場合、建物外壁に沿って横方向に流れる風をスムーズに取り込んで通風効率を高めることができるものの、防犯上の配慮に欠け、また屋外側から建物内部が見える（特に集合住宅では共用部分から居室内が見える）こともあってプライバシー保護の配慮にも欠けることから、特に集合住宅においては使用し難いといった不具合があった。 Further, it is generally performed to ensure ventilation by slightly opening the entrance door to the outdoor side and holding this state with a metal fitting or the like. In this case, the wind flowing in the lateral direction along the outer wall of the building can be smoothly taken in to improve ventilation efficiency, but it is not considered for crime prevention, and the inside of the building can be seen from the outside (particularly in apartment buildings, from the common part) There was a problem that it was difficult to use especially in apartment buildings.
この発明は、上記の不具合を解消して、防犯やプライバシー保護に配慮しながら通風効率を高めることができる通風機能を有するドアの提供を目的とする。 An object of the present invention is to provide a door having a ventilation function that can solve the above problems and can improve ventilation efficiency while considering crime prevention and privacy protection.

It can be operated from the indoor side. Furthermore, an insect screen 24 is stretched so as to cover the indoor side of the ventilation opening 17.
この発明の通風機能を有するドアにおいては、カバー部材を開放状態とすることで、ドア本体の屋外側表面に沿って横方向に流れる風を、風取込口からカバー部材の裏側へスムーズに取り込むとともに、風当たり部を利用して通風用開口部へ効率良く流れ込ませて、屋内へ取り入れることができる。しかも、ドアを閉めて施錠したままで、カバー部材を開放状態とすることができ、さらにカバー部材を開放状態としても、カバー部材によって通風用開口部の屋外側が覆い隠され、屋外側から通風用開口部が見える角度や位置が制限されて、通風用開口部を通して屋内側が見え難くなっている。これにより、防犯やプライバシー保護に配慮しながら、通風効率を格段に高めることができる。 In the door having the ventilation function of the present invention, by opening the cover member, the wind flowing in the lateral direction along the outdoor side surface of the door body is smoothly taken into the back side of the cover member from the wind intake port. At the same time, it is possible to efficiently flow into the ventilation opening by using the wind abutting portion and take it indoors. Moreover, the cover member can be opened with the door closed and locked, and even if the cover member is opened, the outdoor side of the ventilation opening is covered and covered by the cover member. The angle and position where the opening can be seen are limited, making it difficult to see the indoor side through the ventilation opening. Thereby, ventilation efficiency can be improved markedly while considering crime prevention and privacy protection.
また、カバー部材における羽根体の先端部間の横幅を通風用開口部の屋外側の横幅よりも幅広として、それら先端部の裏側に風取込口をそれぞれ形成することで、通風用開口部及び風取込口が屋外側からより一層見え難くなって、ドア自体の見栄えも向上することができる。 Further, the width between the front ends of the blades in the cover member is wider than the lateral width on the outdoor side of the opening for ventilation, and by forming a wind intake port on the back side of each of the front ends, the opening for ventilation and The wind inlet becomes more difficult to see from the outdoor side, and the appearance of the door itself can be improved.
さらに、カバー部材における基体の両側面を風当たり部とすることで、カバー部材の裏側に風当たり部となる部材を別途設けずに済み、また、屋外側から風当たり部が見え難くなることから、構造の簡略化と共に意匠性の向上を図ることができる。 Furthermore, by making the both sides of the base of the cover member wind blowing parts, it is not necessary to separately provide a member that becomes the wind blowing part on the back side of the cover member, and it is difficult to see the wind blowing parts from the outdoor side. Design can be improved with simplification.
また、移動手段を屋内側から操作可能とすることで、屋内に居ながらにしてカバー部材の状態切換を行うことができ、使用性の向上を図ることができる。さらにまた、通風用開口部の屋内側を防虫網で覆うことで、通風時における屋内への害虫の侵入を防止することができる。 In addition, since the moving means can be operated from the indoor side, the state of the cover member can be switched while staying indoors, and the usability can be improved. Furthermore, by covering the indoor side of the ventilation opening with an insect repellent net, it is possible to prevent insects from entering the room during ventilation.

枠部材２１は、左右一対の縦材２１ａ、２１ａと上下一対の横材２１ｂ、２１ｂとを方形枠状に組み付けてなる。この枠部材２１は、ドア本体１０の縦長貫通孔１１に沿って嵌め込まれていて、枠部材２１によって囲まれた部分が屋内外を連通する縦長の通風用開口部１７とされている。また、枠部材２１には、通風用開口部１７の屋内側を覆うようにして防虫網２４が張設されている。さらに、防虫網２４よりも屋外側において、枠部材２１の内周に沿ってシール材２５が方形枠状に取り付けられている。 The frame member 21 is formed by assembling a pair of left and right vertical members 21a and 21a and a pair of upper and lower horizontal members 21b and 21b into a rectangular frame shape. The frame member 21 is fitted along the vertically long through hole 11 of the door body 10, and a portion surrounded by the frame member 21 is a vertically long ventilation opening 17 that communicates indoors and outdoors. Further, an insect screen 24 is stretched on the frame member 21 so as to cover the indoor side of the ventilation opening 17. Further, a seal member 25 is attached in a rectangular frame shape along the inner periphery of the frame member 21 on the outdoor side of the insect screen 24.
カバー部材２２は、ドア本体１０に形成された上記の通風用開口部１７の屋外側を覆い隠すもので、屋内外方向に移動可能に取り付けられて、通風用開口部１７に対向したまま屋外方向へ張り出して通風用開口部１７を開放する開放状態と、屋内方向へ引っ込んで通風用開口部１７を閉塞する閉塞状態とに切換可能とされている。 The cover member 22 covers the outdoor side of the ventilation opening 17 formed in the door main body 10 and is attached to be movable indoors and outdoors, and faces the ventilation opening 17 in the outdoor direction. It is possible to switch between an open state in which the air opening 17 is opened and the air opening 17 is closed and a closed state in which the air opening 17 is closed in the indoor direction.
具体的に、カバー部材２２は、図３及び図４に示すように、通風用開口部１７の幅方向中央付近に対応して配された基体２６と、この基体２６から横方向に互いに離間するように張り出した一対の羽根体２７、２７とを備えている。 Specifically, as shown in FIGS. 3 and 4, the cover member 22 is spaced apart from the base body 26 disposed corresponding to the vicinity of the center in the width direction of the ventilation opening 17 and the base body 26 in the lateral direction. A pair of blade bodies 27, 27 projecting in this manner.
基体２６は、横断面略凸状に形成されていて、一対の羽根体２７、２７よりも屋内方向へ突出されている。一対の羽根体２７、２７は、それら先端部２８、２８間の横幅（カバー部材２２の横幅）が通風用開口部１７の屋外側の横幅よりも幅広とされていて、それら先端部２８、２８の裏側には、屋内方向へ突出するようにシール材２９、２９がそれぞれ取り付けられている。 The base body 26 is formed in a substantially convex shape in cross section and protrudes in the indoor direction from the pair of blade bodies 27 and 27. The pair of blade bodies 27, 27 has a width between the tip portions 28, 28 (width of the cover member 22) wider than the width of the ventilation opening 17 on the outdoor side, and the tip portions 28, 28. The sealing materials 29 and 29 are respectively attached to the back side of the so as to protrude in the indoor direction.
そして、カバー部材２２の開放状態においては、図３及び図５に示すように、基体２６が通風用開口部１７から抜け出すことで、通風用開口部１７が開放されるようになっている。また、一対の羽根体２７、２７における先端部２８、２８の裏側（シール材２９、２９と枠部材２１の縦材２１ａ、２１ａとの間）に、ドア本体１０の屋外側表面１０ａに沿って横方向に流れる風をカバー部材２２の裏側に取り込む風取込口３０、３０がそれぞれ形成され、さらに基体２６における風取込口３０、３０に対向する両側面が、風取込口３０、３０から取り込んだ風を通風用開口部１７へ流れ込ませるように風の流れを切り換える風当たり部３１、３１とされている。 In the open state of the cover member 22, as shown in FIGS. 3 and 5, the base 26 is removed from the ventilation opening 17, so that the ventilation opening 17 is opened. Moreover, along the outdoor side surface 10a of the door main body 10 on the back side (between the sealing materials 29, 29 and the vertical members 21a, 21a of the frame member 21) of the tip portions 28, 28 of the pair of blade bodies 27, 27. Air intake ports 30 and 30 for taking in the wind flowing in the lateral direction are formed on the back side of the cover member 22, respectively, and both side surfaces of the base 26 facing the air intake ports 30 and 30 are provided on the air intake ports 30 and 30. The wind contact portions 31 and 31 are configured to switch the flow of the wind so that the wind taken in from the air flows into the opening portion 17 for ventilation.
カバー部材２２の閉塞状態においては、図４及び図６に示すように、基体２６が通風用開口部１７に収まって枠部材２１のシール材２５に当接することで、通風用開口部１７が閉塞されるようになっている。また、一対の羽根体２７、２７のシール材２９、２９が枠部材２１の縦材２１ａ、２１ａに当接することで、風取込口３０、３０が閉塞されるようになっている。 In the closed state of the cover member 22, as shown in FIGS. 4 and 6, the base 26 is accommodated in the ventilation opening 17 and comes into contact with the seal member 25 of the frame member 21, thereby closing the ventilation opening 17. It has come to be. Further, the air intakes 30 and 30 are closed by the sealing materials 29 and 29 of the pair of blade bodies 27 and 27 coming into contact with the vertical members 21 a and 21 a of the frame member 21.
移動手段２３は、カバー部材２２を屋内外方向に移動させるためのものであって、通風用開口部１７を挟むようにして枠部材２１に取り付けた左右一対のアーム機構３５、３５からなる。アーム機構３５は、屋内側からの操作によって上下方向に回動可能とされた操作レバー３６と、この操作レバー３６の回動に連動して上下動可能とされた支持軸３７と、この支持軸３７の上下動に連動して回動可能とされたアーム材３８とを備えている。 The moving means 23 is for moving the cover member 22 in the indoor and outdoor directions, and includes a pair of left and right arm mechanisms 35 and 35 attached to the frame member 21 with the ventilation opening 17 interposed therebetween. The arm mechanism 35 includes an operation lever 36 that can be turned up and down by an operation from the indoor side, a support shaft 37 that can be moved up and down in conjunction with the rotation of the operation lever 36, and the support shaft. And an arm member 38 that can be rotated in conjunction with the vertical movement of 37.
アーム材３８は、上下方向に沿って配された板状のもので、その上端部３８ａがカバー部材２２の上端部裏側に横軸３９を介して回転自在に連結され、その下端部３８ｂが枠部材２１の支持板４０に横軸４１を介して回転自在に連結され、その中間部３８ｃの屋外側には、支持軸３７に当接する傾斜端面４２が形成されている。 The arm member 38 is a plate-like member arranged along the vertical direction, and its upper end portion 38a is rotatably connected to the back side of the upper end portion of the cover member 22 via a horizontal shaft 39, and its lower end portion 38b is a frame. An inclined end face 42 that is in contact with the support shaft 37 is formed on the outdoor side of the intermediate portion 38c of the member 21 that is rotatably connected to the support plate 40 via a horizontal shaft 41.
そして、屋内側において各アーム機構３５の操作レバー３６を上向きに回動させることで、図５に示すように、支持軸３７が下動するとともに、アーム材３８が屋外方向へ倒れるように横軸４１周りに回動して、これによってカバー部材２２が開放状態となる。また、屋内側において各アーム機構３５の操作レバー３６を下向きに回動させることで、図６に示すように、支持軸３７が上動するとともに、この支持軸３７によって傾斜端面４２が屋内方向へ押し込まれることで、アーム材３８が屋内方向へ立ち上がるように横軸４１周りに回動して、これによってカバー部材２２が閉塞状態となる。この移動手段２３においては、左右のアーム機構３５、３５の操作レバー３６、３６が連結バー４３を介して連結されていて、左右のアーム機構３５、３５が連動するようになっている。このため、カバー部材２２を屋内外方向へバランス良くスムーズに移動させることができ、カバー部材２２を開放状態に確実に保持することができる。 Then, by rotating the operation lever 36 of each arm mechanism 35 upward on the indoor side, as shown in FIG. 5, the support shaft 37 moves downward, and the arm material 38 falls down in the outdoor direction. It rotates around 41, and thereby the cover member 22 is opened. Further, by rotating the operation lever 36 of each arm mechanism 35 downward on the indoor side, as shown in FIG. 6, the support shaft 37 moves upward, and the inclined end surface 42 is moved indoors by the support shaft 37. By being pushed in, the arm member 38 is rotated around the horizontal axis 41 so as to rise in the indoor direction, whereby the cover member 22 is closed. In the moving means 23, the operating levers 36, 36 of the left and right arm mechanisms 35, 35 are connected via a connecting bar 43, and the left and right arm mechanisms 35, 35 are interlocked. For this reason, the cover member 22 can be smoothly moved in a well-balanced direction indoors and outdoors, and the cover member 22 can be reliably held in the open state.
なお、移動手段２３において、カバー部材２２やアーム材３８を屋外方向へ付勢するバネ等を設けても良く、この場合、カバー部材２２を開放状態にしっかりと保持することができる。また、アーム機構３５、３５と併せて、カバー部材２２の下端部付近を屋内外方向にガイドする機構を設けても良く、この場合、カバー部材２２の状態切換を安定して行うことができる。さらに、移動手段２３としては、上記のような構造に限定されず、カバー部材２２を屋内外方向に移動させて状態切換を行わせることができれば、どのような構造のものであっても良い。 In addition, in the moving means 23, you may provide the spring etc. which urge the cover member 22 and the arm material 38 to an outdoor direction, and in this case, the cover member 22 can be hold | maintained firmly in an open state. In addition to the arm mechanisms 35, 35, a mechanism for guiding the vicinity of the lower end portion of the cover member 22 in the indoor / outdoor direction may be provided. In this case, the state of the cover member 22 can be stably switched. Furthermore, the moving means 23 is not limited to the above-described structure, and may have any structure as long as the cover member 22 can be moved indoors and outdoors to change the state.
上記構成の玄関ドア１においては、カバー部材２２を開放状態とすることで、ドア本体１０の屋外側表面１０ａに沿って横方向に流れる風が、風取込口３０、３０からカバー部材２２の裏側へスムーズに取り込まれる。そして、カバー部材２２の裏側に取り込まれた風は、カバー部材２２の裏側の風当たり部３１、３１に当たることで流れが切り換わって、通風用開口部１７へ効率良く流れ込み、防虫網２４を通って屋内へ吹き込むことになる。なお、屋内へ風を取り入れる必要のない場合には、通風ユニット２０のカバー部材２２を閉塞状態とすることで、通風用開口部１７及び風取込口３０、３０がしっかりと閉塞されて、通風を確実に阻止することができる。 In the entrance door 1 having the above-described configuration, the cover member 22 is in an open state, so that the wind flowing in the lateral direction along the outdoor-side surface 10a of the door body 10 flows from the wind intake ports 30 and 30 to the cover member 22. It is smoothly taken into the back side. Then, the wind taken into the back side of the cover member 22 hits the wind contact portions 31, 31 on the back side of the cover member 22, so that the flow is switched to efficiently flow into the ventilation opening 17 and pass through the insect net 24. It will be blown indoors. In addition, when it is not necessary to take in the air indoors, the cover member 22 of the ventilation unit 20 is closed so that the ventilation opening 17 and the air intakes 30 and 30 are tightly closed, and ventilation is performed. Can be reliably prevented.
これにより、換気扇や空調設備を使用せずに屋内へ風を取り入れることができ、しかも従来のような通風機能を有する玄関ドアと比べて、ドア本体１０の屋外側表面１０ａに沿って横方向に流れる風を効果的に捕らえて、通風効率を格段に高めることができる。加えて、玄関ドア１を閉めて施錠したままで、カバー部材２２を開放状態とすることができ、さらにカバー部材２２を開放状態としても、通風用開口部１７に対向するカバー部材２２によって通風用開口部１７の屋外側が覆い隠されて、通風用開口部１７を通して屋内側が見え難くなっていることから、防犯やプライバシー保護にも十分に配慮することできる。 As a result, it is possible to take air indoors without using a ventilation fan or air conditioning equipment, and in the lateral direction along the outdoor side surface 10a of the door body 10 as compared with a front door having a ventilation function as in the prior art. The flowing wind can be captured effectively, and the ventilation efficiency can be greatly increased.
