【発明の属する技術分野】
４輪を有する吊車ユニットと多種の連結具組み合わせによる連結具ユニットとを組み合わせて構成された吊車システムユニットとこのうちの一つの吊車システムユニットを用いて吊引き戸を自閉させ、煙の外部流出を阻止するように構成された遮煙防火戸装置に関するものである。
【０００２】
【従来の技術】
防火戸の場合普通の引き戸に比較して相当重量があるため普通レールに片側１個の車輪を用いて前後で吊下げると１車輪あたり全重量の半分を支えることになり、車輪およびレールに相当負担が掛かるが片側４輪の吊車にすると１車輪あたりは８分の１の重量負担で済み、車輪およびレールにとって好都合である。この片側４輪で形成する吊下げ戸車は古くは防水鉄扉（特許文献１参照）などに使用されており、片側４輪で形成する吊下げ戸車の取付けは４輪の両軸間の中心位置に吊下げ軸を設けて吊戸上面と吊下げ軸とを螺合させるもの（例えば特許文献２参照）や吊戸上面に翼片を設けてこの翼片に上記吊下げ軸を螺合させるもの（例えば特許文献３参照）等がある。

【発明が解決しようとする課題】
しかしながら上記３例の片側４輪で形成する吊下げ戸車は走行方向に対する揺動手段が設けられていないために断面略Ｃ字型のガイドレールを水平取付けした場合に限って使用が可能であり、例えばガイドレールを傾斜配設させて常閉式引き戸に利用しようとする場合には片側の４輪全てをレールに接触させることは不可であり、そのため使用できないという不都合がある。また、この引き戸を開閉させる時、吊車とレールとが金属同士であるため常時開閉を行なう場所においては騒音が高いという不都合がある。本発明はかかる不都合を解決することを目的として提供されたものである。
【０００５】
【課題を解決するための手段】
本発明は片側４輪を有する吊車を用い、更に走行方向に対して揺動手段を設けた上、吊車と引き戸との連結具の種類を各種設けることにより多種多様な引き戸の用途に対応させて掛かる不都合を解決した。すなわち本発明は一つには片方の吊車において車軸が両側板により両持ちで支えられるように構成された本体の外側に４輪車が設けられこの本体下部にはこの４輪車に均等な負荷が掛かる位置に進行方向に揺動可能な連結具を軸連結するための連結穴が設けられて吊車ユニットＡとして構成され、もう片方の吊車が吊車ユニットＡのうち両側板間でしかも上記４輪車の一方の軸部に回転駆動体が設けられこの回転駆動体を介して閉時調速装置が付加されて吊車ユニットＢとして構成され引き戸と上記吊車ユニットＡや吊車ユニットＢとを連結するための連結具は上部分が走行方向に対し揺動可能に連結軸により上記本体の連結穴と軸支連結できるように貫通穴が設けられ下部分が走行方向に対し直角方向に揺動可能に連結軸により軸支連結できるように貫通穴が設けられた連結具Ａと上部分が連結具Ａの下部分と連結軸により軸支連結できるように貫通穴が設けられ下部分が上部分と同方向に揺動可能に連結軸により軸支連結できるように貫通穴が設けられた連結具Ｂと上部分が連結具Ａ下部分もしくは連結部Ｂ下部分と連結軸により軸支連結できるように貫通穴が設けられ下部分が引き戸自身をボルト連結できるように構成された連結具Ｃとまた上部分が走行方向に対し揺動可能に連結軸により上記本体の連結穴と軸支連結できるように貫通穴が設けられ下部分が引き戸自身をボルトで連結できるように構成された連結具Ｄの計４種類の連結具があり、まず上記吊車ユニットＡ、吊車ユニットＢをそれぞれ自在に組み合わせたものと更に連結具Ａ、連結具Ｂ、連結具Ｃ、連結具Ｄをそれぞれ自在に組み合わせて出来上がった連結ユニットとを軸連結することにより用途に応じた吊引き戸用の吊車が構成されることを特徴とする吊車システムユニットであり、また一つはこの吊車ユニットにおける各車輪のガイドレールと接触する表面層部分が静音材料により構成されている吊車システムユニットであり、また一つはこれらの吊車システムユニットのうち吊車ユニットＡ、吊車ユニットＢ、連結具Ａ、連結具Ｂ、連結具Ｃを用い断面が略Ｃ字型のガイドレールを用いて構成した常閉式防火戸装置である。ここで静音材料とはゴム、プラスチックあるいはそれらの合成物などからなる材料を指し、重量防火戸に対しても通常時に吊車の変形などによって途中停止しないものであれば耐熱耐火性は問題としないものである。
【０００６】
本発明は開口部３方と防火戸とで防火遮煙構造を形成させる場合の想定を単に閉じるだけで防火遮煙構造が出来る場合、開口部３方と当接する防火戸の間に遮煙部材を挟んで閉じた時に初めて防火遮煙構造が出来る場合、そして閉じた際に防火戸を遮煙部材側に押圧して初めて防火遮煙構造が出来る場合、更に防火戸下部の開口部側に遮煙部材を設けて開口部周縁４方を塞いだ場合に初めて防火遮煙構造が出来る場合と分類したがこれらはそれぞれのケースにおいて確かな遮煙構造が形成できることを想定している。
【０００７】
【発明の実施の形態】
発明の実施の形態を図に基づいて説明すると実施例１は吊車システムユニットである。図１は吊車ユニットＡの正面図、図２は図１のＡ−Ａ断面図でこれは２枚の側板１、１とこの２枚の側板間距離を一定に保つための複数個のディスタンスカラー２とにより一体化された本体３の外側に４つの車輪４が設けられ、本体３の下部にはこの４輪車に均等な負荷が掛かる位置に進行方向に揺動可能な連結具を軸連結するための連結穴５が設けられたものである。
【０００８】
図３は吊車ユニットＢの上面図で吊車ユニットＡとの共通部分は断面で描いたものである。２枚の側板１、１間でしかも４輪車の一方の軸部に回転駆動歯車６が設けられ、この回転駆動歯車６を介して増速歯車列７が設けられ最終歯車と発電機８の軸に設けられたワンウェイクラッチ（図示せず）付の歯車とが連結され防火戸閉鎖時のみ発電機８が回転して吊車ユニットＢにブレーキが掛かるように構成された調速装置２９が付加されたものである。
【０００９】
図４（Ａ）は連結具Ａの正面図、図４（Ｂ）はその側面図であり、上部分が走行方向に対し揺動可能に上記本体の連結穴５と連結軸９により軸支連結できるように貫通穴１０が設けられ下部分が走行方向に対し直角方向に揺動可能に連結軸９により軸支連結できるように貫通穴１０が設けられたものである。
【００１０】
図５（Ａ）は連結具Ｂの正面図、図５（Ｂ）はその側面図であり、上部分が連結具Ａの下部分と連結軸９により軸支連結できるように貫通穴１０が設けられ下部分が上部分と同方向に揺動可能に連結軸９により軸支連結できるように貫通穴１０が設けられたものである。
【００１１】
図６（Ａ）は連結具Ｃの正面図、図６（Ｂ）はその側面図であり、上部分が連結具Ａ下部分もしくは連結部Ｂ下部分と連結軸９により軸支連結できるように貫通穴１０が設けられ下部分が引き戸自身をボルト留めできるように構成されたものである。
【００１２】
図７（Ａ）は連結具Ｄの正面図、図７（Ｂ）はその側面図であり、上部分が走行方向に対し揺動可能に上記本体の連結穴５と連結軸９により軸支連結できるように貫通穴１０が設けられ下部分が引き戸自身をボルト留めできるように構成されたものである。
【００１３】
これらの連結具は連結具Ｄ単独使用で引き戸が進行方向のみに揺動可能でその直角方向には揺動不可。連結具Ａと連結具Ｃとの組み合わせ使用で引き戸が進行方向のみに揺動可能でその直角方向には一軸で揺動可能となり、連結具Ａと連結具Ｂと連結具Ｃとの組み合わせ使用で引き戸が進行方向のみに揺動可能でその直角方向には２軸で揺動可能となり計３種類の連結具ユニットが構成されることになって上記吊車ユニットＡ同士、吊車ユニットＡと吊車ユニットＢとの組み合わせなどそれぞれ自在に組み合わせて軸連結することにより吊車システムユニットが出来上がって用途に応じた吊引き戸用の吊車システムユニットを構成することができる。なお、上記連結具Ａ〜Ｄは構成が同じであれば形状はどのようなものであっても良い。
【００１４】
実施例２は上記吊車システムユニットを用いた応用例の一つの常閉式遮煙防火戸装置であり、図８は通路開口部に常閉式遮煙防火戸装置を設けた正面図、図９は図８におけるＢ−Ｂ断面図、図１０は図８におけるＣ−Ｃ断面図である。図に基づいてその構成を説明すると開口部１２のうち開口部上枠１３と開口部戸尻側縦枠１４とに弾性を有する遮煙部材１５を設け、戸先側については開口部側の防火戸戸先側縦枠１６にも弾性を有する遮煙部材１５を設けたものである。
【００１５】
壁側に断面略Ｃ字型のガイドレール１７が防火戸閉鎖方向に傾斜されて敷設されこの傾斜敷設ガイドレール１７内に吊車ユニットＡ１８と吊車ユニットＢ１９とが設けられこの両方の吊車ユニットのそれぞれに連結具Ａ、連結具Ｂ、連結具Ｃが順次軸連結されて組合わされ防火戸１１が吊下げられてなる常閉式遮煙防火戸装置である。また、防火戸１１下部の開口部側溝壁内戸幅全体にも図１１に示すように遮煙部材１５が設けられており全閉時に初めてこの遮煙部材１５は接地するように構成され、これは全閉時に開口部３方と防火戸下部とで周縁４方で防火遮煙構造になるように構成させたものである。また、ガイドレール１７の傾斜分は連結具Ｃと防火戸１１との間にライナー２０を挿入することにより調整して防火戸１１はいつも床と水平に保つように構成されている。
【００１６】
次に動作を説明するとガイドレール１７が傾斜されて設置されているため防火戸１１は一旦開放されると自動的に閉鎖される。そして閉鎖時には防火戸１１は吊車ユニットＢ１９に設けられた調速装置２９により加速されることなく調速されてゆっくりと閉じる。そして全閉時には開口部上枠１３と開口部戸尻側縦枠１４と防火戸戸先側縦枠部１６との開口部三方枠に設けられた弾性を有する遮煙部材１５と防火戸１１とが接触して隙間を閉塞するため火も煙もそこを通過することが出来ない。
【００１７】
実施例３は実施例２で用いた吊車ユニットにおける各車輪のガイドレール１７と接触する表面層部分をプラスチック材料２１にしたもので図１２は実施例３における吊車ユニットＡの正面図であり、吊車ユニットＢの車輪もまた同様の構成である。これは防火戸１１の開閉の際にガイドレール１７と吊車２２との金属同士の接触による騒音を軽減させたもので仮に火災などの熱により溶解しても内部が径の小さいに車輪になるため防火戸１１は容易に閉鎖することが出来る。
【００１８】
実施例４は実施例２や実施例３の防火戸１１の上部と下部に押圧手段として図１３と図１４に示すようにうしろに平行部をもったクサビ状の変位具２３と回転体２４とをそれぞれ設けたものである。防火戸下部の場合下部溝２５内に設けられた防火戸１の振れ止めローラを回転体２４として使用し、溝壁にクサビ状の変位具２３を設けて振れ止めローラによって防火戸１１を開口部側に押圧させるように構成したものである。この押圧手段は全閉時に防火戸１１が遮煙部材１５により強く押圧されるためより隙間の閉塞性が高くなって遮煙効果は上昇する。この場合変位具２３はうしろに平行部をもったクサビ状のものでも、平行部をもたないクサビ状のものでも良い。
【００１９】
実施例５は図１５に示すように実施例４の上部における押圧手段の代わりにクランクアーム２６と転向ブラケット２７と押圧ブラケット２８とにより回転モーメントを利用して押圧するように構成したものであり、その動作は閉鎖時クランクアーム２６の長棹側先端の回転体が転向ブラケット２７にあたるとクランクアーム２７は回動して短棹側先端の回転体が押圧ブラケット２８にあたって次第に防火戸１１を開口部側に押圧してゆき全閉時には確実に隙間を塞ぐことになる。この場合押圧力は梃子の原理により小さな閉鎖力でも確実に防火戸１１を開口部側に押し付ける働きをする。
【発明の効果】
本発明の装置は防火戸閉鎖方向に傾斜配設されたガイドレールを用いているために自動閉鎖装置を備える必要がなくて安価であり、ドア重量が吊車ユニットのそれぞれの車輪に分散されるため普通の単体吊車に比較して小さな負荷を支えれば良いので吊車の寿命が延びるし、またその分、断面略Ｃ字型のガイドレールの厚みも薄くすることが出来て製造単価も下がる。また開口部三方枠周縁部と防火戸との間に弾性を有する遮煙部材が設けてあり、防火戸は進行方向と直角方向に対しては２軸で連結されているため開口部周縁全面にわたって密着させることが出来、更に全閉時は押圧手段により防火戸が押圧されるため開口部と防火戸とがより密着されて遮煙効果が高くなる。また閉鎖時は調速手段を備えているため防火戸閉鎖時における加速による恐怖からも解放されるし指詰めの心配もない。

[0014]
Example 2 is a normally closed type smoke-proof fire door device as an application example using the above suspension vehicle system unit, FIG. 8 is a front view in which a normally closed type smoke-proof fire door device is provided at the passage opening, and FIG. 8 is a BB cross-sectional view in FIG. 8, and FIG. 10 is a CC cross-sectional view in FIG. The structure will be described with reference to the drawings. The opening upper frame 13 and the opening door bottom side vertical frame 14 of the opening 12 are provided with a smoke shielding member 15 having elasticity, and the door side is fireproof on the opening side. The door-end side vertical frame 16 is also provided with a smoke shielding member 15 having elasticity.
[0015]
A guide rail 17 having a substantially C-shaped cross section is laid on the wall side so as to be inclined in the fire door closing direction, and a suspended vehicle unit A18 and a suspended vehicle unit B19 are provided in the inclined installed guide rail 17, and each of these suspended vehicle units is provided. This is a normally closed smoke-proof fire door device in which the fire retardant door 11 is suspended by connecting the joint A, the joint B, and the joint C in order. Further, as shown in FIG. 11, a smoke shielding member 15 is also provided in the entire width of the opening side groove wall inside the lower part of the fire door 11, and the smoke shielding member 15 is configured to be grounded only when fully closed. Is configured such that when fully closed, a fireproof smoke-insulating structure is formed on the periphery 4 side with the opening 3 side and the fire door lower part. The inclination of the guide rail 17 is adjusted by inserting a liner 20 between the connector C and the fire door 11, so that the fire door 11 is always kept level with the floor.
[0016]
Next, the operation will be described. Since the guide rail 17 is installed inclined, the fire door 11 is automatically closed once it is opened. And at the time of closing, the fire door 11 is speed-controlled without being accelerated by the speed control device 29 provided in the suspension vehicle unit B19, and closes slowly. And when fully closed, the smoke shielding member 15 and the fire door 11 having elasticity provided in the opening three-way frame of the opening upper frame 13, the opening door bottom side vertical frame 14, and the fire door end side vertical frame portion 16, Contact and close the gap, so neither fire nor smoke can pass through it.
[0017]
In the third embodiment, the surface layer portion in contact with the guide rail 17 of each wheel in the suspension unit used in the second embodiment is made of a plastic material 21, and FIG. 12 is a front view of the suspension unit A in the third embodiment. The wheel of unit B has the same configuration. This reduces the noise caused by metal contact between the guide rail 17 and the suspension wheel 22 when the fire door 11 is opened and closed, and even if it is melted by heat such as fire, the inside becomes a small diameter wheel. The fire door 11 can be easily closed.
[0018]
In the fourth embodiment, a wedge-shaped displacement tool 23 and a rotating body 24 having a parallel portion as shown in FIGS. 13 and 14 as pressing means on the upper and lower portions of the fire door 11 of the second and third embodiments. Are provided respectively. In the case of the lower part of the fire door, the steady roller of the fire door 1 provided in the lower groove 25 is used as the rotating body 24, the wedge-shaped displacement tool 23 is provided on the groove wall, and the fire door 11 is opened by the steady roller. It is comprised so that it may be pressed to the side. When the pressing means is fully closed, the fire door 11 is strongly pressed by the smoke shielding member 15, so that the gap is more closed and the smoke shielding effect is increased. In this case, the displacement tool 23 may be wedge-shaped with a parallel part behind or wedge-shaped with no parallel part.
[0019]
As shown in FIG. 15, the fifth embodiment is configured such that the crank arm 26, the turning bracket 27, and the pressing bracket 28 are pressed using a rotating moment instead of the pressing means in the upper part of the fourth embodiment. When the rotating body at the front end of the long side of the crank arm 26 hits the turning bracket 27 when the crank arm 26 is closed, the crank arm 27 is rotated and the rotating body at the front end of the short side contacts the pressing bracket 28 to gradually move the fire door 11 to the opening side. When it is fully closed, the gap is surely closed. In this case, the pressing force works to reliably press the fire door 11 against the opening side even with a small closing force due to the principle of the lever.
【The invention's effect】
Since the apparatus of the present invention uses guide rails inclined in the fire door closing direction, there is no need to provide an automatic closing device, and the door weight is distributed to each wheel of the suspension unit. As long as a small load is supported as compared with an ordinary single suspension vehicle, the life of the suspension vehicle is extended, and the thickness of the guide rail having a substantially C-shaped cross section can be reduced correspondingly, thereby reducing the manufacturing unit price. In addition, a smoke shielding member having elasticity is provided between the peripheral edge of the opening three-way frame and the fire door, and the fire door is connected in two axes with respect to the traveling direction and the direction perpendicular to the traveling direction. Further, when the door is fully closed, the fire door is pressed by the pressing means, so that the opening and the fire door are brought into close contact with each other, and the smoke shielding effect is enhanced. In addition, it is equipped with speed control means when closed, so you can be freed from the fear of acceleration when the fire door is closed and you don't have to worry about fingering.
