<P>PROBLEM TO BE SOLVED: To provide a shoelace hooking device capable of hooking a shoelace without passing the shoelace by means of a pulley with an asymmetric structure for the shoelace hooking device, subsequently pulling the shoelace upward to tighten the shoelace, easily tying up the shoelace since the tightened shoelace does not get loose after tightening the shoelace, and further easily removing the shoelace from the shoelace hooking device. <P>SOLUTION: After the pulley is attached to a hooking support part shaped to mount the pulley having the asymmetric structure having one side surface part havign a diameter larger than that of the other side surface part of the disk-shaped side surface parts for a groove of the pulley for guiding the shoelace and preventing the detachment thereof, a rotational pin is inserted into a shaft of each pulley so that the pulley is rotatably attached to the hooking supporting part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
