Description

Improved structure of the pad body of the ventilating insole

technical field

The present invention relates to an improved pad body structure of a ventilating insole, in particular to an improved elastic pad composed of an upper insole with an air inlet and an outlet, a lower insole and a foam pad with a smaller interlayer area. Insole; when the upper insole is formed, the contact surface with the sole of the foot is provided with several protruding surfaces with air inlets at the lower edge of the heel; and several arbitrary shapes are arranged on the forefoot, and several grooves are arranged at the bottom of the groove. There are grooves distributed in each air outlet, and a foam pad with high density and compression resistance is used, and several small holes are punched on the foam pad; while in the arch of the foot that is not under pressure, densely punched A number of large holes are provided; the effect of the structure to achieve air circulation and ventilation can be significantly enhanced.

Background technique

Existing insoles with a ventilation function are equipped with air chambers, and the upper insoles above the air chambers are in contact with the soles of the feet. An air inlet is provided at the heel position, and several air outlets are set up at the forefoot position.

For example, see US Patent 4215492, Aug.05, 1980; US Patent 5010661, May30, 1991; US Patent 5333397, Aug.02, 1994; US Patent 4224746, SeP.30, 1980; WO97/04676A1, Feb.13, 1997 ; China's new patent 925176, 07/18/2007 insole with ventilation function and other patent records.

In the air chamber inside the insole, there are foam pads (or sponge pads) to fill in and install, then there are US patent 4224746, SeP.30, 1980; US patent 6006447, Dec.28, 1999; WO97/04676A1; China's new patent 925176, 07/18/2007 and other patent records.

However, the ventilating insole structure that can be seen in the above-mentioned workshops and previous patent cases, because if the upper insole in contact with the sole of the foot is a flat surface, when the foot is lifted off the ground, if the shoe is tight, the air inlet is easily covered by the heel. It makes it difficult for air to flow into the air chamber from the air inlet; when the foot presses down on the insole, if the air outlet is covered by the sole of the foot, the air inside the air chamber is not easy to flow out from the air outlet, and the common disadvantage of unsmooth air circulation .

Moreover, if the air chamber of the above-mentioned ventilating insole structure is composed of upper and lower insoles and a foam pad in the middle, the foam pad with large gaps and low density has a large air capacity, but it is easy to be flattened due to elastic fatigue; On the contrary, the foam pad with small gap and high density has the advantage of good elasticity and is not easy to be crushed, but the air capacity is small, the air is not easy to circulate, and the air passes through the foam pad with high density, and there will be impact friction. The disadvantage of the heat source occurs.

Contents of the invention

The main purpose of the present invention is to provide an improved structure of the pad body of a ventilating insole; wherein, on the front of the upper insole in contact with the sole of the foot, a gentle cone or other shaped cylinder or cone is provided on the heel. Protrude; so that several air inlets are set at the lower edge of the protruding surface. When the wearer lifts his foot off the ground, the protruding surface will withstand the heel, and the air inlet at the lower part will not be covered by the heel, and the air is easy to pass through. The intake port flows into the air chamber; this has the positive effect of sufficient intake air entering the air exchange.

The second object of the present invention is still to provide an improved structure of the pad body of the ventilating insole; wherein, some grooves are arranged on the front of the upper insole and the forefoot, and several air outlets are arranged in the groove, when wearing shoes When the person walks and steps on the insole, the forefoot will not cover the air outlet, and the air in the air chamber will easily flow out from the air outlet; thereby achieving the positive effect of smooth ventilation.

Still another object of the present invention is to provide an improved pad body structure for ventilating insoles; wherein, a foam pad with small voids and high density is used, and several small holes are distributed and punched on the foam pad; Several large holes can be densely punched in the arch of the foot to increase the air capacity and facilitate the circulation of air; thereby achieving the effect of large flow of ventilation.

Detailed ways

The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

Please refer to Figure 1, Figure 1-A and Figure 2, Figure 2-A first:

It can be clearly understood that the main purpose of the present invention is that when the plastic material 12, 12A such as cloth or leather 11, 11A can be glued on the surface, when the insole 1, 1A is integrally formed, the heel portion of the front 1-1, 1A-1 must be provided with a protrusion. Face 18, 18A; and several air inlets 15, 15A are set at edge 17, 17A of protrusion face 18, 18A; and described protrusion face 18, 18A can be gentle cone (as shown in Figure 1-A) , or other shapes of cylinders, cones, etc. (as shown in Figure 2-A) are applicable.

Among them, the setting of the protruding surface 18, 18A can be made when the upper insole 1, 1A is integrally formed; it can also be changed to stick the protruding piece 181, and protrude on the heel of the upper insole 1, 1A. (As shown in Figure 1-B), the effect of setting the protruding surface 18 as shown in Figure 1-A is also achieved.

In addition, when the upper insole 1 is integrally formed, some grooves 19, 19A are set at the front part P2 of the front part 1-1, 1A-1, and several air outlets 16 are set in the grooves 19, 19A. , 16A. Upper insole 1 bottom surface 1-2, 1A-2, during one-piece molding, a housing groove 14, 14A is recessed in the central part, and frame encirclement 13, 13A is formed around its housing groove 14, 14A, and then in the housing groove 14. A foam pad 2 with the same profile is placed in 14A; and the foam pad 2 is a kind of elastic, porous, air-permeable foamed article made of different materials.

Then the frame surrounding 13, 13A formed around the accommodation groove 14, 14A is attached to the lower insole 3, thus forming the frame surrounding 13, 13A formed around the lower insole 3, 3A and the upper bottom surface of the shoe pad 1-2, 1A-2 Bonding can form a ventilating insole of an air chamber R (for example, refer to Fig. 3-A and Fig. 3-B).

Through the above structure, as shown in Figure 3-A: when the wearer uses the improved ventilating insole of the present invention to walk, when the wearer lifts his feet off the ground, the raised protruding surface 18 will withstand the heel P1, so that The air inlet 15 arranged at the lower place will not be covered by the heel P1, and a large amount of air AIR can easily flow into the air chamber R from the air inlet 15, so as to achieve the effect of active ventilation.

As shown in Figure 3-B again: when the wearer uses the improved ventilating insole of the present invention to walk, when the shoe is worn and the foot is stepped on and presses down on the insole, the overhead groove 19 will make the said insole located at a low place The air outlet 16 will not be covered by the soles of the feet P2, so that the air AIR in the air chamber R can easily flow out from the air outlet 16; the effect of smooth and smooth air exchange can be achieved.

As shown in Fig. 3-A and Fig. 3-B again: the ventilating insole of the present invention can adopt the foam pad 2 that the gap is small and the density is bigger, distributes and sets several small holes 21 on the foam pad 2; In the pressure part of the foot arch P3, a number of large holes 22 can be densely punched, so that the air capacity of the foam pad 2 can be increased during the compression and recovery process, and it can also help the air circulation to achieve a large flow of ventilation Effect.

The above descriptions are only preferred embodiments of the present invention, and are only illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
