AUTOMATIC CLOSING DOOR
PROBLEM TO BE SOLVED: To provide an automatic closing door with a simple constitution while minimizing the space for installing a door.SOLUTION: An automatic closing door comprises a door part for blocking a passage, an opening/closing shaft in an edge part of the door part which rotates according to the opening/closing of the door part, a support cylindrical member for supporting the rotation of the opening/closing shaft, and a pivotally supported rolling body in the outer periphery of the opening/closing shaft for supporting a load of the door in the shaft direction of the opening/closing shaft. An edge surface of the support cylindrical member has an inclined surface spirally formed inclining to the horizontal surface. The rolling body rolls along the inclined surface of the support cylindrical member according to opening/closing of the door part. When the door part is closed, the rolling body is positioned in the lower part of the inclined surface. When the door part is opened, the rolling body is positioned higher than when the door part is closed.SELECTED DRAWING: Figure 1
【課題】扉を設置するスペースを最小限に抑えつつ、簡易な構成で自動的に閉鎖する自動閉鎖扉を提供する。【解決手段】自動閉鎖扉は、通路を閉鎖する扉部と、扉部の端部に設けられ、前記扉部の開閉に伴い回転する開閉軸と、開閉軸の回転を支持する支持円筒部材と、開閉軸の外周に設けられ、開閉軸の軸方向に扉の荷重を支持する軸支された転動体と、を備える。支持円筒部材の端面は、水平面に対し傾斜して螺旋状に構成された傾斜面を備える。転動体は、扉部の開閉に伴い前記支持円筒部材の前記傾斜面に沿って転動し、扉部が閉まっているときには前記傾斜面の下部に位置し、扉部が開いているときには、扉部が閉まっているときよりも上方に位置する。【選択図】図１
