<p><P>PROBLEM TO BE SOLVED: To provide a door which is strongly and tightly closed without being accelerated or causing an impact when closed, which can be opened with a weak force, and which is closed while reducing a speed. <P>SOLUTION: This door comprises a revolver which transfers revolution to the door only in a turning section until just before the full closing of the door from the start of the closing, and a tight closing device which transfers the revolution to the door only in the turning section from the time immediately before the full closing of the door onward to the tight closing of the door. The door continues the operation of the device even if a relay from the revolver to the tight closing device is performed for the temporary stop of the turning of the door, and reduces the speed by changing an inertial force, acting on the door immediately before the full closing, to resistance. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
