<P>PROBLEM TO BE SOLVED: To provide an automatic safe rotary door of a wide opening width opened and closed both in right and left directions. <P>SOLUTION: A wing door and an intrusion blocking sidewall door 10 are freely movable by detecting an obstacle in an opening process, or are opened by providing an energizing means, and the rotation of a rotary door body 3 is stopped at the same time. The rotary door body 3 is stopped in this side of the obstacle, so that the wing door keeps a stop distance or more of width. A storage sidewall door 1 is made to go ahead by the stop distance or more of width from the rotary door body 3, in another method. The storage sidewall door 1 and the intrusion blocking sidewall door 10 are freely movable by detecting the obstacle in the opening process, or are opened by providing the energizing means, and the rotation of the rotary door body 3 is stopped at the same time. The rotary door body 3 stops in this side of the obstacle, since the storage sidewall door 1 is made to go ahead by a width equivalent to the stop distance or more. <P>COPYRIGHT: (C)2010,JPO&INPIT |
