Device for penetrating and tying shoelace and capable of rapidly releasing shoelace

Abstract

The invention provides a device for penetrating and tying a shoelace and capable of rapidly releasing the shoelace; the two sides of a shoelace seat are respectively provided with a telescopic shoelace fastener which is formed by connecting by a connecting arm by at least one sleeve joint part and shoelace penetrating part; the bottom end of each shoelace fastener is combined with the bottom of the shoelace seat; furthermore, the tops of the two shoelace fasteners are combined into a pull handle piece; a sliding groove of the shoelace seat is provided with at least one pulley in a sliding way, and the pulley is connected with the sleeve joint part; the tops at the two sides of the shoelace seat are also provided with two hook parts; and the two shoelace fasteners are stretched by the pull handle piece upwards and then are hooked with the two hook parts for locating. The device for penetrating and tying the shoelace and capable of rapidly releasing the shoelace is used for more rapidly and conveniently wearing or separating shoes.

Description

technical field [0001] The invention relates to a shoelace tying device for shoes, in particular to a device for quickly putting on and taking off shoes on feet. Background technique [0002] At present, there are many kinds of shoes on the market, such as sports shoes, casual shoes, or leather shoes, which are covered styles, which are usually tied with shoelaces on both sides of the tongue, or adhered to each other by magic sticks, so that the shoes It can be fixed on the feet while walking to avoid falling off. Among various fixing methods, shoelace fixing is the most secure. [0003] However, for lace-up shoes, the tight shoelaces must be loosened before the feet are put in, so that the tongue can be turned slightly so that the feet can be put into the shoes. The belt is tied tightly (commonly tied into a bow). However, although shoelaces are fixed as the most secure way, tying shoelaces is still tricky, especially when children wear shoes because they cannot tie shoel...

AI Technical Summary

Problems solved by technology

However, since the telescopic sliding fastening body is only provided with the telescopic arch bridge 212' on one side, that is, the fastening body is stressed on one side, therefore, the parallel state between the slider 21' and the chute 11' will deviate, resulting in The sliding block 21' is stuck in the chute 11' so that the operation of the telescopic sliding fastening body 2' is suspended. At this time, it is necessary to adjust the position of the sliding block 21' and the direction and magnitude of the external force in time so that the sliding block 21' can continue to be stable. ground slide in the chute 11';

[0005] Second, when the shoelaces are tightened, once there is an external force impact between the fixed buckle 12' and the movable slider 22', the two may be separated, thereby causing the shoelaces to loosen;

[0006] Third, since the telescopic arch bridge 212' on the slider 21' is arched when the shoelaces are loosened, and the telescopic arch bridge 212' is linear when the shoelaces are tightened, the material of the telescopic arch bridge 212' It must have considerable flexibility and anti-fatigue strength to ensure the normal operation of the device; in addition, the arched shape of the telescopic arch bridge 212' can easily cause children's fingers to get stuck in it, causing unpredictable injuries;

[0007] Its four, when fastening or loosening shoelace, need to pull two pull rings 221 ' respectively, if these two pull rings 221 ' are too big, then it is not attractive in appearance, if it is too small, it is not easy to stretch into fingers to pull;

[0008] Finally, the structural design of the shoelace fastening device is relatively complicated, thereby increasing the manufacturing cost
