Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an insole with improved internal air circulation, and in particular to a unique shoe insole to promote foot comfort with air circulation under the feet, so that the heat and moisture accumulation around the wearer's feet can be considerably reduced. [0003] 2. The Related Art [0004] The insole is applied into the interior of shoes that allows the insole to conform to the contour of the sole of a particular wearer's shoes to enhance comfort in wearing. [0005] The main functions of the insole insert are to reduce the heat and moisture accumulation, and prevent impact related foot, leg and back strains, so that joins and spine can be more relieved. Some manufacturers claim that their insoles are able to control foot odor, while others claim that the general fitness and the circulation can be improved, and the risks for the germs to grow can also be lowered, after using their insoles for certain time. [0006] There have been many different kinds of shoe insole available, using different materials and designs. Many of those may have some of the effects claimed by the original manufacturers, and yet research efforts to make more comfortable footwear and with orthopedic support for the foot have never ceased. SUMMARY OF THE INVENTION [0007] The primary objective of the present invention is to provide an insole with improved internal air circulation, having air vents evenly distributed on the top and bottom surfaces, and mixed pattern of channels and nodes embedded in the body of the insole, so that air circulation is created under the feet to help reduce heat and moisture accumulation inside the wearer's shoes. [0008] In accordance with one aspect of the invention, the insole with improved internal air circulation is composed of a cover layer and a main body, where the cover layer is provided with air vents on the top surface, and the main body is embedded with mixed pattern of channels and nodes and a plurality of air vents evenly distributed on the bottom surface, corresponding to the recessed areas of the channels and nodes. [0009] In accordance with another aspect of the invention, the main body of the insole is made from foam rubber such as polyurethane (PU) and ethyl vinyl acetate foam (EVA), or thermoplastic rubber (TPR), or flexible foam plastic. The composite materials for making the main body of the insole may be composed of two or more kinds of the above-mentioned materials. [0010] In accordance with still another aspect of the invention, the cover layer of the insole is a thin membrane made of leather skin, cloth, microfiber fabric or composite material containing charcoal-based nanoparticles. [0011] In accordance with still another aspect of the invention, the cover layer of the insole is provided with a plurality of air vents evenly distributed on the top surface. [0012] In accordance with still another aspect of the invention, the insole embedded with nodes and channels and surface perforation is capable of producing air circulation under the feet. As a result of that, the heat and moisture accumulation around the wearer's feet can be considerably reduced. [0013] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0014] FIG. 1 is a plan top view of the present invention; [0015] FIG. 2 is a plan view of the main body of the insole in accordance with the present invention; and [0016] FIG. 3 is a perspective view of the main body of the insole. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0017] With reference to the drawings and in particular to FIGS. 1 and 2, an insole 1 constructed in accordance with the present invention comprises a cover layer with surface perforation and a main body embedded with mixed pattern of nodes and channels to allow the air to circulate under the feet. [0018] The cover layer of the insole 1 is provided with a plurality of air vents 2 evenly distributed on the top surface, and the main body of the insole 1 is embedded with mixed pattern of channels 3 and nodes 4 spreading across the entire surface area. [0019] The cover layer of the insole 1 is a thin membrane made of leather skin, cloth, microfiber fabric, or composite materials containing charcoal-based nanoparticles. [0020] The main body of the insole 1 is made from foam rubber, thermoplastic rubber (TPR), or flexible foam plastic, where the foam rubber material can be polyurethane (PU) or ethyl vinyl acetate foam (EVA). The composite materials for making the insole may be composed of two or more kinds of the above-mentioned materials. Continue reading about Insole with improved internal air circulation...
