A shoelace device

Abstract

The invention discloses a shoelace tying device. The shoelace tying device mainly comprises a slide rod, pullers, a tightness adjusting button, pawls, a slide rail and a pull wire, wherein one ends ofthe pullers are connected with a shoelace, the other ends of the pullers are provided with the pawls, and the pullers can drive the shoelace and the pawls to slide on the slide rod; the pawls and ratchets on the slide rod form a ratchet mechanism, and the slide rail is mounted in the slide rod, and can drive the pawls to move left and right for controlling the meshing and separation of the pawlswith the ratchets; two ends of the pull wire are connected with the slide rail and the tightness adjusting button; when the shoelace needs to be tied, the pawls and the ratchets are meshed to form theratchet wheel mechanism, the pullers are pulled for driving the shoelace to move unidirectionally towards the rear direction of a shoe, thus the shoe is tied and self-locking is realized; when the shoelace needs to be loosened, the tightness adjusting button is pressed down, the pull wire pulls the slide rail to move towards the rear direction of the shoe, a leaf spring enables the slide rail tomove towards the inner side of the shoe and drives the pawls to be separated from the ratchets, the pullers can slide forwards on the slide rod, consequently, the shoelace tying device is pulled backwards, and the shoelace is loosened. With the shoelace tying device, the shoelace can be conveniently and rapidly tied or loosened.

Description

technical field [0001] The invention discloses a shoelace device, in particular to a tool capable of quickly fastening and loosening shoelaces. Background technique [0002] Usually, the shoelace is passed through the shoelace eyelet of the shoe, and then the shoelace is knotted to fasten the shoelace. But the mode of such fastening and loosening shoelace, operating process is relatively more complicated, often also can occur the situation of beating dead knots, brings inconvenience to people. Moreover, with such a fastening method, during people's walking, the shoelaces will become loose as time goes on, and there is a possibility of automatic loosening in the end. Once this happens, if the shoelaces are hooked by other objects Or one's own other foot steps on the shoelace, which not only damages the shoelace, but also may cause an accidental fall of the personnel. Especially children and the elderly are particularly prominent in the face of the above problems. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing shoelace device has played a certain effect on optimizing the shoelace, it is a pity that there are two key problems that have not been well resolved: one is that the locking function of the shoelace device is basically By squeezing or clamping the shoelaces, this structure is easy to damage the shoelaces, and there is also the possibility that the shoelaces may become loose due to too long time; second, the shoelaces will leave a long section outside after tightening, which not only affects the appearance , and there is a possibility of being hooked by other objects or stepping on shoelaces
