Kind Code:
A1
Abstract:
A pull-free structure applied to shoes, comprising a sole (100). An automatic springback structure (200) is arranged at a heel position of the sole (100); the automatic springback structure (200) comprises two springback pieces (210) which are symmetrically arranged, supporting parts (220), and an outward turning part (230); one ends of the two springback pieces (210) are respectively provided with the L-shaped supporting parts (220); the outward turning part (230) is of a tongue-shaped structure bent outwards; the opposite ends of a tongue tip of the outward turning part (230) are respectively connected to the other ends of the two springback pieces (210); the angle of the tongue tip of the outward turning part (230) is 120°-160°; the inner angle of the included angle between each supporting part (220) and the outward turning part (230) is 125°-145°; the bending angle of the outward turning part (230) is 85°-110°. In application to kids' shoes, the difficulties in sliding heels in and tying shoes for students during getting shoes on after getting up are solved; in application to the middle-aged, elderly, obese or patients, the trouble of bending down to pull heels up and tie shoes can be reduced.
