Abstract

A puncture-proof and breathable insole comprises a bottom layer of a cushion body, an air cushion body, a metal sheet, and an elastic body. The rear lower surface of the air cushion body has a groove body, the front lower surface has a plurality of crisscross grooves, and a plurality of ventilation holes penetrating the air cushion body. The metal foil is located between the bottom of the cushion body and the air cushion body, and its outline size is at least equal to the contour formed by the lower surface of the air cushion body. The metal foil covers the groove body to form a rear air chamber, and covers a plurality of grooves to form a cross airway. The elastic body is placed in the rear air chamber. Therefore, the metal foil can simultaneously form a relatively closed air chamber and a hard shell that prevents foreign bodies from puncturing the sole.

Description

Anti-puncture and breathable insole

This creation relates to the structure of an insole, especially a breathable insole with anti-puncture function.

Please refer to the breathable insole disclosed in Patent Document M440670, which mainly generates multiple air passages connected to the outside of the insole body at the bottom of the insole body corresponding to the position of the sole of the foot, forming air chambers corresponding to the position of the foot, allowing the user to wear shoes when stepping on , To squeeze the air in the rear air chamber, so that the bottom of the insole body produces an airflow that circulates toward the front, so as to produce cushioning and ventilation effects.

This type of breathable insole forms a tight air chamber through the contact between the insole body and the bottom of the insole body to provide a cushioning effect. In other words, the degree of tightness of the two cushion bodies will affect the cushioning capacity of the air chamber. Room for improvement.

This creation provides a puncture-proof and breathable insole comprising a bottom layer of a cushion body, an air cushion body, a metal sheet, and an elastic body. The rear lower surface of the air cushion body has a groove body, the front lower surface of the air cushion body has a plurality of crisscross grooves, and the air cushion body has a plurality of vent holes penetrating and communicating with a plurality of grooves. The metal foil is located between the bottom of the cushion body and the air cushion body. The contour size of the metal foil is at least equal to the contour formed by the lower surface of the air cushion body. The metal foil covers the groove body to form a rear air chamber, and covers a plurality of grooves to form a cross air passage. The elastic body is placed in the rear air chamber.

Such a breathable insole can be closely attached to the bottom of the air cushion body through the metal foil to form a relatively closed air chamber to provide cushioning properties of the air cushion. In addition, the metal foil itself can also be used as a hard shell to prevent foreign bodies from puncturing the sole.

Further, the lower surface of the air cushion body forms a plurality of supporting pads between the crisscross grooves. Therefore, the supporting pad contacts the metal sheet, so that the plurality of grooves form a cross air channel.

Furthermore, the air cushion body forms a cushioning convex portion on the upper surface of the back, which further provides a cushioning effect.

Further, a plurality of ventilation holes are arranged at the junction of the plurality of grooves, and at least one groove of the air cushion body extends to the outer contour of the air cushion body to form an air inlet and outlet.

Further, the surface layer of the air cushion body includes a woven or non-woven fabric layer to absorb sweat and maintain the comfort of the soles of the feet.

Fig. 6 is a schematic diagram of the use of the anti-puncture and breathable insole.

Please refer to FIG. 1 to FIG. 6, which is a puncture-proof and breathable insole 10, which includes a cushion body bottom layer 30, a metal sheet 50, a sponge elastic body 40 and an air cushion body 20 arranged in order from bottom to top.

The bottom layer 30 of the cushion body is used as the bottom of the insole 10, and is a cushion body with a concave middle part and an outer contour extending outward and upward. The middle part of the bottom part of the cushion body 30 is flat and matches the outer contour of the metal foil 50 for positioning the metal片50。 Flake 50.

The lower surface of the air-cushion body 20 has a groove formed in the rear corresponding to the position of the foot, and defines the space of the rear air chamber 210. The lower surface of the air-cushion body 20 also has a plurality of grooves that cross each other, between the plurality of grooves. A plurality of supporting pads 23 arranged at intervals are generated. The air cushion body 20 also has a plurality of vent holes 25 penetrating from the upper surface to the lower surface. The vent holes 25 are arranged at the junction of the plurality of grooves. Therefore, the vent holes 25 are connected to the plurality of grooves.

In addition, a cushioning protrusion 21 is formed behind the upper surface of the air cushion body 20 to further provide a cushioning effect to the base of the foot.

In this embodiment, the metal sheet 50 is an iron sheet or a steel sheet, and the outline size of the metal sheet 50 is at least equal to the outline formed by the lower surface of the air cushion body 20. When overlapping sequentially, the support pad 23 contacts the metal foil 50, so that a plurality of grooves form a cross airway 22. The support pad 23 can also distribute the force of the sole of the foot on the metal foil 50 evenly and increase air tightness.

The metal foil 50 covers the rear trough at the same time to form a rear air chamber 210, so that the sponge elastic body 40 is accommodated in the rear air chamber 210. When walking in shoes, the sponge elastic body 40 is used to provide elasticity and recover from being squeezed by the roots of the feet. Pressure of the rear air chamber 210.

The breathable insole of the present invention is tightly attached to the bottom of the air cushion body 20 through the metal sheet 50. Compared with the hard cushion body bottom layer 30, the rear air chamber 210 can form a relatively closed rear air chamber 210, and the air cushion The deformation of the groove at the rear of the cushion body 20 is increased, so that it can provide cushioning force when walking. In addition, the metal foil 50 itself can also be used as a way to prevent the sole from puncturing by sharp objects. The hard shell achieves the safety effect of foot protection, so the breathable insole of this creation can be applied to work shoes.

In addition, at least one groove on the lower surface of the air cushion body 20 also extends to the outer contour of the air cushion body 20 to form an air inlet and outlet 24. When walking, the squeeze and release of the foot force on the cushion protrusion 21 can not only be compressed and expanded by the sponge elastic body 40 in the rear air chamber 210, but also can be connected to the air inlet and outlet 24 and the outlet through the cross airway 22 The ventilation hole 25 achieves the effect of ventilation and breathability on the sole of the foot.

In addition, the upper surface of the air cushion body 20 can also be attached with a woven fabric layer or a non-woven fabric layer to absorb sweat and improve the comfort of contact with the soles of the feet.

The above descriptions are merely illustrative and not restrictive. Any equivalent modifications or alterations that do not depart from the spirit and scope of the present invention should be included in the scope of the appended patent application.
