Benefits of technology

The present invention provides a ventilating insole structure that allows for fresh air to flow in or out of shoes, providing an air change effect. The insole structure includes an upper insole, foam pad, and lower insole. The lower insole can be replaced with a sole, making it cost-effective and convenient for use. The insole structure also has a notch that can receive a foam lug or air guide pipes to prop up the upper and lower insoles. Additionally, the insole structure can keep the insole dry and clean by discharging water from the foam pad through the air port when washed.

Problems solved by technology

The structure is complicated and the cost is high.
When the user's trousers cover the vamp, it is not easy to guide external air into the shoe.
However, it is difficult to make these insoles and the cost is high.

second embodiment

[0036]FIG. 3, FIG. 3-A, and FIG. 4 show the present invention. The second embodiment is substantially similar to the first embodiment with the exceptions described hereinafter. The circumferential wall 13, 13A close to the heel portion of the upper insole 1, 1A, is provided with one or a plurality of notches 15, 15A configured to receive an air guide pipe 4 therein. The air guide pipe 4 corresponds in number and in shape to the notch 15, 15A for the rear end of the foam pad 2 to extend out rearward. The air guide pipe 4 is to prop up the upper insole 1, 1A and the lower insole 3, 3A at the notch 15, 15A for the air between the upper and lower insoles to enter and exit so as to achieve an air change effect.

[0037]The bottom of the heel portion of the shoe S is formed with an air outlet S2 corresponding to the notch 15, 15A. The air guide pipe 4 extends outward to be fitted in the air outlet S2. A distal end of the air guide pipe 4 can extend out of the shoe S to circulate the air for ...

third embodiment

[0038]FIG. 5, FIG. 5-A, and FIG. 6 show the present invention. The third embodiment is substantially similar to the second embodiment with the exceptions described hereinafter. The circumferential wall 13, 13A close to the heel portion of the upper insole 1, 1A, is provided with one or a plurality of notches 15, 15A configured to receive a converting pipe 5 therein. The converting pipe 5 corresponds in number to the notch 15, 15A for the rear end of the foam pad 2 to extend out rearward. The converting pipe 4 is to prop up the upper insole 1, 1A and the lower insole 3, 3A at the notch 15, 15A for the air between the upper and lower insoles to enter and exit so as to achieve an air change effect. Wherein, a distal end of the converting pipe 5 is connected with a socket 61 of an L-shaped sleeve 6 to form a bent and extendable air passage. The sleeve 6 can be hidden at the inner side of the shoe S. A distal end of the sleeve 6 can extend out of the shoe. The converting pipe 5 and the L...

fourth embodiment

[0039]FIG. 7 and FIG. 7-A show the present invention. The fourth embodiment is substantially similar to the first embodiment with the exceptions described hereinafter. The foam pad 2 is fitted in the accommodation trough 12 of the upper insole 1 by the circumferential wall 13, and then attached to a top surface of a sole 7, such that the foam pad 2 is sandwiched and positioned between the upper insole 1 and the sole 7. The bottom of the heel portion of the sole 7 is formed with an air outlet 71 corresponding to the foam lug 21 extending from the rear end of the foam pad 2, such that the foam lug 21 can extend outward for the air to enter and exit so as to achieve an air change effect. The sole 7 is combined with the upper insole 1 and the foam pad 2 having the foam lug 21 to constitute a simple and ventilating sole structure.

[0040]FIG. 8 and FIG. 9 show a fifth embodiment of the present invention. The foam pad 2 is fitted in the accommodation trough 12, 12A of the upper insole 1, 1A...

Abstract

A ventilating insole structure includes an upper insole, a foam pad, and a lower insole. The upper insole is formed with air vents, an accommodation trough, and a circumferential wall around the accommodation trough. The foam pad is shaped to fit in the accommodation trough. The circumferential wall is configured to enclose the foam pad and the lower insole. The circumferential wall close to a heel portion of the upper insole is provided with a notch. The notch is to receive a foam lug extending from the foam pad or one or multiple air guide pipes to prop up the upper and lower insoles at the notch. In operation with an air outlet of a shoe, the foam lug and the air guide pipe can extend outward as an air passage for fresh air to flow in or out of the shoe so as to circulate air.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a ventilating insole structure, and more particularly to a ventilating insole structure composed of an upper insole, a lower insole, and a middle foam pad sandwiched between the two insoles. The insole is formed with a notch relative to the heel portion of the foam pad to receive a foam lug or an air guide pipe. When in use, the ventilating insole structure is able to guide fresh air into or out of the shoe to provide an air change effect.[0003]2. Description of the Prior Art[0004]In general, an insole able to change air has an air chamber, an upper insole above the air chamber, an air inlet at a heel portion thereof, and a plurality of air vents at a toe portion thereof. The structure is complicated and the cost is high. When in use, the air inlet and air vents may be covered by the user's heel or toes. When the user's trousers cover the vamp, it is not easy to guide external air into t...
