Embodiment Construction

[0019]Referring to FIG. 1 and FIG. 2, the mechanism of the thorn-proof insole comprises an insole assembly 10 and a plurality of joint assemblies 20 featuring in matching the shape change of the sole of a foot when the insole assembly 10 is extended. The insole assembly 10 includes four plates 11a / 11b / 11c / 11d which are consecutively joined together. The joint of the first plate 11a and the second plate 11b is located between a user's toes and thenar, the joint of the second plate 11b and the third plate11c is corresponding to the middle portion of the arch of foot, and the joint of the third plate 11c and the fourth plate 11d is located between the arch of foot and the heel portion. The four plates 11a, 11b, 11c and 11d could be designed with the same thickness or with different thickness according to the requirement of its location. Each plate must be at least 0.5 mm thick and be made of metal such as iron or alloy.

Abstract

The present invention relates to a thorn-proof insole comprising an insole assembly and a plurality of joint assemblies and featuring in matching the shape change of the sole of a foot when the insole assembly is extended. The insole assembly includes four plates which are consecutively joined together. The joint of the first plate and the second plate is located between a user's toes and thenar, the joint of the second plate and the third plate is corresponding to the middle portion of the arch of foot, and the joint of the third plate and the fourth plate is located between the arch of foot and the heel portion. The four plates could be designed with the same thickness or with different thickness according to the requirement of its location. Each plate must be at least 0.5 mm thick, and each joint assembly includes at least two first sleeves, one second sleeve and one pin. The first sleeves and the second sleeve are respectively applied to make two adjacent plates join together.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a thorn-proof insole, particularly to an insole having the function of thorn-proof. The insole is also flexible to match the shape of the user's foot while a user is walking. This invention is designed for users to wear their shoes with much better comfort and safety.BACKGROUND OF THE INVENTION[0002]Based upon the concern of workers' safety at commonly seen dangerous working places, such as construction sites or fields requiring moving heavy objects etc., workers not only need to secure the safety of their heads, but also need to protect their feet from danger as well. The prior art of security work shoes are equipped with hard hulls at the head portions of the shoes to protect user's toes and to prevent user's feet from being crashed by heavy objects. Nevertheless, nails or sharp objects are often scattered all over the floors of work places. The hard hulls of the shoes can only protect workers' toes not to be crashed, bu...
