TIGHTENING HANDLE FOR USE WITH AIRTIGHTNESS DOOR
PROBLEM TO BE SOLVED: To provide a tightening handle for use with an airtightness door handle which is configured such that a pressed seal material can be peeled easily from an inner surface of a side plate of a guide rail when the airtightness door is subjected to release its airtightness in order to allow the airtightness door to be removed easily from an opening portion of a structure.SOLUTION: When an airtightness door 14 is closed in an airtightness manner, the resulting rotation of an operation arm 35 in the airtightness direction causes, via a movement conversion mechanism 36, to slide a slide pin 33 in a Y1 direction, resulting in that a Y1 side end of the slide pin is in abutment with an inner surface of a side plate 17 placed on a Y1 side of a guide rail 13. Thereafter, further rotation of an operation arm 35 in the airtightness direction, under a condition that the slide pin 33 is pushing the inner surface of the side plate 17 at the Y1 side, causes airtightness door 14 to move in a Y2 direction with the end portion of the slide pin 33 abutting against the inner surface of the side plate 17 as a fulcrum. As a result, the sealing member 26 is pressed against the inner surface of the side plate 18 on a Y2 side and the sealing door 14 is closed in an airtightness manner.SELECTED DRAWING: Figure 1
【課題】密閉扉の密閉解除時、ガイドレールの側板の内面から、押し付けられたシール材を容易に剥離でき、構造物の開口部分からの密閉扉の撤去作業が容易な密閉扉用締込ハンドルを提供する。【解決手段】密閉扉１４の密閉時、操作アーム３５の密閉方向への回動に伴い、運動変換機構３６を介して、スライドピン３３がＹ１方向へスライドし、そのＹ１側の端部がガイドレール１３のＹ１側の側板１７の内面に当接する。その後も、操作アーム３５を密閉方向へ回動することで、Ｙ１側の側板１７の内面をスライドピン３３が押しながら、この側板１７の内面に当接したスライドピン３３の端部を支点にして、密閉扉１４をＹ２方向へ移動させる。その結果、シール材２６がＹ２側の側板１８の内面に圧着され、密閉扉１４が密閉される。【選択図】図１
