<P>PROBLEM TO BE SOLVED: To provide a sash pulley for a folding door panel with which a folding door panel can be opened and closed smoothly, and an automatic folding door system employing the sash pulley. <P>SOLUTION: A sash pulley for a folding door is provided which runs along a guide rail provided within an upper frame. The sash pulley comprises a running part which runs along the guide rail while being interlocked with horizontal movement of a wire body provided within the upper frame, and a hanging part having a connecting shaft which converts the horizontal movement into horizontal rotation, rotates the folding door panel and hangs the folding door panel. The hanging part includes an operational plate which transfers the horizontal movement of the wire body and operates on a modified rotary plate fixed to the connecting shaft to rotate the connecting shaft, a rack which transfers the horizontal movement of the operational plate, and a gear train which converts the horizontal movement of the rack to a horizontal rotation force. A lower end side of the connecting shaft is fixed to an upper end of the folding door panel while using a rotary shaft of an output rotary gear of the gear train as the connecting shaft, and the folding door panel is hung and rotated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
