PROBLEM TO BE SOLVED: To provide a highly durable automatically closing door that hardly corrodes or malfunctions even when used in an environment with a corrosive substance and dust.SOLUTION: An automatically closing door 1 includes a support post 2 having a pair of inclined grooves 5 formed in a top part, a rotary body 3 covering the top part of the support post 2, a door body 4 extending in a horizontal direction from a side part of the rotary body 3, and a bolt 6 fitted on an inner side of the rotary body 3 and inserted into the pair of inclined grooves 5. The inclined groove 5 comprises a first inclined groove 5a and a second inclined groove 5b that are symmetrical with regard to a central axis of the support post 2, and has a height that increases from an end toward the other end. When force is exerted on the door body 4 in a closed position from a front surface toward a rear surface, the bolt 6 located at the end of the inclined groove 5 is guided by the inclined groove 5 and moves to the other end side, raising the rotary body 3 and the door body 4 while rotating counterclockwise. When the force on the door body 4 is released, the rotary body 3 and the door body 4 are lowered while rotating clockwise, thereby bringing the bolt 6 back to the end of the inclined groove 5 and closing the door body 4.SELECTED DRAWING: Figure 1
【課題】腐食性物質や塵の存在する環境で使用されても、腐食や動作不良が生じ難く、耐久性の高い自動閉鎖扉を提供する。【解決手段】自動閉鎖扉１は、上部に１対の傾斜溝５が形成された支柱２と、支柱２の上部を覆う回動体３と、回動体３の側部から水平方向に延びる扉本体４と、回動体３の内側に取り付けられ、１対の傾斜溝５に挿通されたボルト６を備える。傾斜溝５は、支柱２の中心軸に関して対称の第１の傾斜溝５ａと第２の傾斜溝５ｂで構成され、一端から他端に向かって高さが増大している。閉鎖位置にある扉本体４に、正面から背面に向かう力が作用すると、傾斜溝５の一端に位置するボルト６が傾斜溝５に案内されて他端側へ移動し、回動体３と扉本体４が反時計回りに回動しながら上昇する。扉本体４への力が解放されると、重力により回動体３と扉本体４が時計回りに回動しながら下降し、ボルト６が傾斜溝５の一端に戻って扉本体４が閉鎖する。【選択図】図１
