Abstract:
The present invention relates to a quick tightening structure for a single shoelace, comprising an upper (10), a shoe tongue (20), a pair of stoppers (40), a saw-tooth rotary body (50), and a single shoelace winding device (60). The upper (10) has a fixing member (11) which is arranged below eyelet flaps where the shoe tongue (20) is disposed, to fix one end of a single shoelace (30), and at least one or more eyelets or rings (12) which are formed along opposing eyelet flaps to enable the passage of the single shoelace (30). The shoe tongue (20) closes the space between the eyelet flaps of the upper (10). The pair of stoppers (40) is arranged on the respective upper portions of the eyelet flaps of the upper (10), and includes a first guide hole (41) and a second guide hole (42) for the passage of the single shoelace (30). The saw-tooth rotary body (50) is rotatably arranged in each of the stoppers (40), and has an outer surface with saw teeth for friction with the single shoelace (30). The single shoelace winding device (60) is mounted on the bottom of a shoe to draw the single shoelace (30) by an elastic means (61) connected to one end of the single shoelace (30).
