〔産業上の利用分野〕
クリーンルーム等の清浄空間の出入口を自動的に気密に
閉塞して外気よシ清浄空間内を保護し、且つ出入する時
はシール押圧力を解除しドアーの開閉を楽に行なえ、沓
ズリも必要としないドアー関する発明である。[Detailed description of the invention] [Industrial application field] Automatically airtightly closes the entrance and exit of a clean space such as a clean room to protect the inside of the clean space from outside air, and releases the seal pressing force when entering and exiting. This invention relates to a door that can be opened and closed easily and does not require slipping.
従来クリーンルーム等の出入口のドアーの気密を保つに
は上部及び左右は壁体の扉枠にパツキンを、又、下部に
は沓ズリにパツキンを設けて気密を保っていた。しかし
下部の沓ズリは搬送よぼすものである。Conventionally, to maintain the airtightness of the entrance/exit door of a clean room, etc., gaskets were installed on the door frame of the wall at the top and left and right sides, and gaskets were installed on the bottom part of the door in order to maintain the airtightness. However, the slippage at the bottom is caused by transportation.
クリーンルームの沓ズリが悪影響をおよぼすという問題
点及びドアーと壁との確実な気密性が得られないという
問題点を解決しようとするものである。This is an attempt to solve the problem that the leakage of the clean room has an adverse effect and the problem that reliable airtightness between the door and the wall cannot be obtained.

し、ドアーとその外周部とのシール押圧力を解くことに
より気密を保持しだシ解放したりするものである。Tubes are provided on the top, bottom, left and right sides of the door to maintain airtightness around the door, and when the door is opened, the air supply valve is closed and the exhaust valve is opened to exhaust the air in the tubes, allowing the door and its outer periphery to be airtight. By releasing the pressure on the seal, the airtightness is maintained and released.

アー（１１は簡単に開けることができる。According to the above structure, when opening the door (1), the limit switch α3) (14) is set to the ratchet α when the knob 0 is rotated and the ratchet αυ is retracted from the recess Oz.
When released from contact from υ, limit switch 03)
The contact point opens and the solenoid valve (7) closes, and the air pump (3) stops to stop feeding air. The contact on the limit switch side closes and operates the solenoid valve (8) to open the tube (2).
) is exhausted and becomes ≠day←,
, Since the pressing force of the tube (2) is released, the door (11) can be opened easily.
