<p><P>PROBLEM TO BE SOLVED: To provide a platform door device which can save a storage space below a platform when a door is vertically opened and closed. <P>SOLUTION: The platform door device is arranged in parallel to the side end of the platform PH. The platform door device is provided at a rising/falling door 2 which draws a circular movement trajectory, and a housing 70 which is installed below the platform PH. The platform door device is equipped with a driving slider 27 which vertically moves, and a link 36 which converts the up-and-down movement of the driving slider 27 into the rotating movement of the door 2. One end of the link 36 is rotatably coupled with the lower part of the door 2. At the other end, the link 36 is cam-coupled with a guide cam groove 51 for positioning formed so as to be inclined toward the driving slider 27 and the movement trajectory of the driving slider 27 by the engagement of pins or grooves. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
