上記従来の不都合を伴うことなく室内外の差圧を効果的に解消することができる。   The differential pressure inside and outside the room can be effectively eliminated without the conventional disadvantages.

以下、図面を参照して、本発明の一実施の形態を説明するが、本発明は図示実施形態自体に限定されないことは言うまでもない。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to the illustrated embodiment itself.

図１を参照すると、壁１には、ドア枠３が固定設置され、ドア枠３の内側側部には、ドア５が蝶番７によって回動自在に取り付けられる。
ドア５の蝶番７とは反対の側の略中央には、空錠９が、その上側および下側には、互いに異なった形式の本締錠１１、１３がそれぞれ設置される。 Referring to FIG. 1, a door frame 3 is fixedly installed on a wall 1, and a door 5 is rotatably attached to an inner side portion of the door frame 3 by a hinge 7.
An empty lock 9 is installed at the approximate center opposite to the hinge 7 of the door 5, and different types of main locks 11 and 13 are installed on the upper and lower sides thereof.

空錠９は、錠前を具備していないので戸締まり（施錠）できないが、ラッチを具備しているので閉まった状態を維持できる錠装置からなる。
下側の本締錠１１は、施錠するためのデッドボルト（かんぬき）が横方向に突没し得る錠装置（通常の市販品）からなる。特に、図示実施形態のそれは、ボルトが鎌の形をした防犯性の高い鎌錠となっている。 The empty lock 9 does not have a lock and cannot be locked (locked). However, the empty lock 9 has a latch and can be kept closed.
The lower main lock 11 is composed of a lock device (ordinary commercial product) in which a dead bolt for locking can protrude and retract in the lateral direction. Particularly, in the illustrated embodiment, the bolt is a sickle lock having a sickle shape and a bolt.

ここで、図２も参照すると、上側の本締錠１３は、横方向および上方向にデッドボルト１５がそれぞれ突出（前後動）する２点施錠式の錠装置（通常の市販品）からなる。
横方向に突出するデッドボルト１５ａは、本来通り施錠のために使用され、特に、図示実施形態のそれは、ボルト先端が鎌の形をした防犯性の高い鎌錠となっている。 Here, referring also to FIG. 2, the upper main lock 13 is composed of a two-point locking type locking device (ordinary commercially available product) in which the dead bolt 15 protrudes (moves back and forth) in the lateral direction and the upward direction.
The dead bolt 15a protruding in the lateral direction is used for locking as usual, and in particular, in the illustrated embodiment, the bolt tip is a sickle lock with a sickle shape having a sickle shape.

上下動する他方のデッドボルト１５ｂは、施錠のために使用されず、代わりに、水平方向に延びるバー部材１７に作動連結されている。
バー部材１７は、ドア５内部の上側において、上下方向に並進的に往復上下動（上下に平行移動）できるように支持されている。 The other dead bolt 15b that moves up and down is not used for locking, but is instead operatively connected to a bar member 17 extending in the horizontal direction.
The bar member 17 is supported on the upper side inside the door 5 so as to be able to reciprocate up and down (translate up and down) in translation in the vertical direction.

他方、図３に示すように、ドア上面に対向するドア枠３（上枠）の外面すなわち下面（水平面）には、所定間隔で複数の通気口２１が形成されている。なお、通気口２１を複数ではなく１つだけ設けるような構成にすることもできる。   On the other hand, as shown in FIG. 3, a plurality of vent holes 21 are formed at predetermined intervals on the outer surface, that is, the lower surface (horizontal surface) of the door frame 3 (upper frame) facing the upper surface of the door. In addition, it can also be set as the structure which provides only one vent hole 21 instead of plurality.

ドア枠３の内部には、内部空間Ａが形成され、通気口２１から離れた個所には、室内に開口する換気口２３が形成されている。内部空間Ａは、通気口２１と換気口２３とを結ぶ空気流通のための内部経路Ａを構成している。この内部経路Ａは、図３から理解され得るように、光漏れや音漏れを軽減ないしはなくすために、凹凸状を呈する蛇行路を構成している。   An interior space A is formed inside the door frame 3, and a ventilation opening 23 that opens indoors is formed at a location away from the ventilation hole 21. The internal space A constitutes an internal path A for air circulation that connects the vent 21 and the vent 23. As can be understood from FIG. 3, the internal path A constitutes a meandering path having an uneven shape in order to reduce or eliminate light leakage and sound leakage.

詳細には、ドア枠３（内部空間Ａ）の中には、通気口２１に実質上平行に対向するように第１の邪魔板２５（図では水平方向に延びる）が設けられる。そこから進んだ位置には、第２の邪魔板２７（図では天地方向に延びる）が設けられ、そこから更に進んだ位置には、第３の邪魔板２９（図では天地方向に延びる）が設けられる。第３の邪魔板２９は、換気口２３に実質上平行に対向する。   Specifically, a first baffle plate 25 (extending in the horizontal direction in the figure) is provided in the door frame 3 (internal space A) so as to face the vent hole 21 substantially in parallel. A second baffle plate 27 (extending in the vertical direction in the figure) is provided at a position advanced from there, and a third baffle plate 29 (extending in the vertical direction in the figure) is provided at a position further advanced from there. Provided. The third baffle plate 29 faces the ventilation port 23 substantially in parallel.

このように、内部経路内の主たる空気の流れ方向に対して交差する方向に少なくとも１枚の邪魔板が設けられ、そのために、遮音効果・遮光効果が飛躍的に向上させることができる。   As described above, at least one baffle plate is provided in a direction intersecting with the main air flow direction in the internal path. Therefore, the sound insulation effect and the light shielding effect can be drastically improved.

なお、ドア枠３内部に内部空間Ａを形成する上記構成に代えて、通気口および換気口を連通する内部経路を含みつつドア枠とは別体に形成した装置（内部空間を構成する装置）をドア枠に後付けするような構成にすることもできる。すなわち、本実施形態では、ドア枠（上枠）に差圧解消機構（内部経路ないし連通装置）を組み込んで一体化しているが、これに代えて、別体の装置として製造して、それをドア枠に後付け設置するような構成が可能である。   In addition, it replaces with the said structure which forms the interior space A inside the door frame 3, and is the apparatus (apparatus which comprises interior space) formed separately from the door frame, including the internal path | route which connects a vent hole and a ventilating hole. Can be configured to be retrofitted to the door frame. That is, in this embodiment, the door frame (upper frame) is integrated with a differential pressure release mechanism (internal path or communication device), but instead, it is manufactured as a separate device, It can be configured to be retrofitted on the door frame.

以上の構成を有する本実施形態においては、ドア５が閉じられて施錠された場合、施錠作動に連動してデッドボルト１５ｂが上動して、バー部材１７が並進的に上昇してドア枠３（上枠）の上面（水平面）に全体的に当接・係合する。これにより、ドア枠３の通気口２１を効果的に塞ぐことができ、室内を室外から隔離、すなわち、室内の気密性を形成することができる。好ましくは、通気口２１の閉塞性を高めるために、バー部材１７と通気口２１との間には、所定のシール板が配置構成される。   In the present embodiment having the above-described configuration, when the door 5 is closed and locked, the dead bolt 15b moves up in conjunction with the locking operation, and the bar member 17 moves up in translation, so that the door frame 3 Abuts and engages with the upper surface (horizontal plane) of the (upper frame) as a whole. Thereby, the vent 21 of the door frame 3 can be effectively blocked, and the room can be isolated from the outside, that is, the air tightness of the room can be formed. Preferably, a predetermined seal plate is disposed between the bar member 17 and the vent 21 in order to increase the closing property of the vent 21.

他方、ドア５の施錠が解除された場合、解錠作動に連動してデッドボルト１５ｂが下動して、バー部材１７が並進的に下降してドア枠３の外面から引き離される。これにより、ドア枠３の通気口２１が開放され、室内の隔離状態を解消できる。すなわち、内部経路（上枠）を空気が通り抜けて、室内外の圧力差が緩和（解消）される。したがって、特にドア開時に起き得る室内外の圧力差による不快な「ドアが重くて開けにくい」現象を見事に緩和・解消することが可能になる。ドア閉時においても、同様な効果を得ることができる。   On the other hand, when the door 5 is unlocked, the dead bolt 15 b is moved downward in conjunction with the unlocking operation, and the bar member 17 is lowered in translation to be separated from the outer surface of the door frame 3. Thereby, the vent 21 of the door frame 3 is opened, and the indoor isolation state can be eliminated. That is, air passes through the internal path (upper frame), and the pressure difference between the room and the outside is relaxed (resolved). Therefore, the unpleasant phenomenon that “the door is heavy and difficult to open” due to the pressure difference inside and outside the room that can occur particularly when the door is opened can be relieved and eliminated. Similar effects can be obtained even when the door is closed.

また、ドア周りの外観に殆ど影響を及ぼさないデザインが可能であるので、様々な建築物に適用・応用でき、非常に実用的・実際的である。
さらに、本実施形態のドア構造によれば、防火性能、遮音性能、気密性能、断熱性能等を従来と同等もしくはそれ以上に維持・向上することができる。 In addition, since the design that hardly affects the appearance around the door is possible, it can be applied and applied to various buildings and is very practical and practical.
Furthermore, according to the door structure of this embodiment, the fireproof performance, the sound insulation performance, the airtight performance, the heat insulation performance, and the like can be maintained and improved to be equal to or higher than those of the conventional one.

また、通気口２１を高い位置に設けることができるので、音漏れや光漏れといった不都合を回避することができ、また、セキュリティ上も好適である。また、通気口２１および換気口２３の双方を外観から目立たない位置に設けることができるので、すなわち、見え掛かり位置に設けないようにできるので、人に違和感を与えることがない。
本実施形態によれば、本締錠（錠装置１３）および上下動部材（デッドボルト１５ａ）として、それらの機能を単体で有する市販品（２点施錠式の錠装置）を流用・転用して合理的に装置構成できるので合理的・経済的である。 Moreover, since the vent 21 can be provided at a high position, inconveniences such as sound leakage and light leakage can be avoided, and security is also preferable. Moreover, since both the vent hole 21 and the vent hole 23 can be provided at a position that is not conspicuous from the appearance, that is, it can be prevented from being provided at an apparent position, the person does not feel uncomfortable.
According to the present embodiment, as the final locking (locking device 13) and the vertical movement member (dead bolt 15a), a commercially available product (two-point locking type locking device) having these functions alone can be diverted and diverted. It is rational and economical because it can be configured rationally.

本発明は、上述したように本実施形態に限定されるものではなく、本発明の要旨の範囲内、すなわち、特許請求の範囲に記載された範囲内で、各種の改変・変形実施が可能である。   The present invention is not limited to the present embodiment as described above, and various modifications and changes can be made within the scope of the gist of the present invention, that is, within the scope described in the claims. is there.
