Abstract

(57) [Abstract] [Purpose] When using shoes with poor breathability such as safety shoes, the purpose is to prevent stuffiness inside the shoes due to sweat from the feet. [Structure] In a shoe insole, a batting made of a super absorbent resin is sandwiched between a top member having a large number of small holes penetrating and a bottom member having a large number of small holes penetrating, and the batting and the upper surface. An insole for shoes, characterized in that a moisture-permeable paper is interposed between the member and between the batting and the bottom member.

[0001]

[Industrial applications]

 The present invention relates to the improvement of insoles.

[0002]

[Prior art]

 Traditional insoles have leather (shikikawa) and hemima to improve the contact of the uneven sole with the sole of the foot. These are used to adjust the fit of oversized shoes. It was also used for Also, copper wire is embedded in the insole to prevent or treat athlete's foot by the action of copper ions, and the heel of the insole is thickened to make it look taller. It was

[Problems to be solved by the device]

 It is an object of the present invention to prevent stuffiness (unevenness) inside shoes due to perspiration from the feet when using shoes with poor ventilation such as safety shoes.

[0004]

[Means for Solving the Problems]

 The insole has a laminated structure, and a padding made of a highly water-absorbent resin is sandwiched between a top member having a large number of small holes penetrating and a bottom member having a large number of small holes penetrating. A moisture-permeable paper was interposed between the upper and lower members and between the batting and the bottom member, and then the whole was sewn.

[0005]

[Action]

 Since the top and bottom members have a large number of small holes penetrating the members, sweat from the foot in the shoe can freely pass through these small holes and be absorbed by the batting made of high-grade water-based resin. Retained.

The moisture-permeable paper soaks and permeates the sweat that has passed through the small holes and sends it to the batting, and at the same time, the fibers or fragments of the batting are passed through the through-holes of the upper surface member or the lower surface member. Prevent it from leaking to the outside.

Since the batting is made of a super absorbent resin, it absorbs and retains perspiration that has penetrated through the moisture permeable paper.

Further, the top member, the bottom member, the moisture permeable paper and the batting are laminated and sewn together to form an integral insole, so that the respective constituent members do not shift freely.

[0009]

【Example】

 With reference to the drawings, when one embodiment of the present invention is shown, (1) is a top member, (2) is a bottom member, (3) is moisture permeable paper, and (4) is batting. The top surface member (1) and the bottom surface member (2) are paper-like bodies having smooth surfaces, and through-holes (5) penetrating the front and back sides are perforated on the surface. The paper-like body forming the top surface member (1) and the bottom surface member (2) may be either natural paper such as kraft paper or chemical paper such as polystyrene paper. In either case, it is sufficient that it be strong enough to be used as an insole of shoes and have good slipperiness. The diameter, number and perforation interval of the small through holes (5) may be appropriately selected depending on the type and material of the member, but a circular hole having a diameter of about 1 to 3 mm per surface member, It is suitable to drill 100 to 150 holes. The shape of the through small hole (5) may not be circular, but may be polygonal, rectangular, or the like. If the member has a breathable mesh structure, it is not necessary to perforate.

The moisture-permeable paper (3) soaks and permeates sweat that has passed through the small through holes (5) of the upper and lower surface members (1) and (2), absorbs it into the batting (4), and at the same time batting The purpose is to prevent the fibers and fiber fragments of (4) from leaking to the outside through the small through holes (5) of the upper and lower surface members (1) and (2). Use paper.

The batting (4) is a super absorbent resin (for example, polyacrylic acid-based resin) used for sanitary materials, laminated in a thickness of about 1 to 2 mm. It is the easiest and cheapest to use fibrous super absorbent resin, but the application of the shoes to be used (eg safety shoes, water boots, mountain boots, ski shoes, etc.) Depending on the situation, a sheet-shaped or film-shaped highly water-absorbent resin may be used.

In the figure, the top member (1), the moisture permeable paper (3), the batting (4), the moisture permeable paper (3) and the bottom material (2) are stacked in this order, and the whole is sewn with sutures. Although the case (6) is shown, when chemical paper is used for the top member (1), the moisture permeable paper (3) and the bottom member (2), it can be welded and sewn with a high frequency sewing machine.

[0013]

[Effect of device]

 Since the present invention is configured and operates as described above, it has the following effects. Since the batting (4) is made of super absorbent resin, if you use the insole of the proposed shoe, all the sweat from your feet will be absorbed by the batting (4) even in the case of shoes with poor breathability. It doesn't get damp, and it's extremely comfortable to work for a long time. You don't feel uncomfortable with wet shoes and you don't have to worry about athlete's foot. Since super absorbent polymer can absorb and retain a very large amount of water and moisture, the amount of batting (4) can be small, the overall thickness of the insole is thin, and when used in shoes, There is no discomfort. When the batting (4) is dried, it releases moisture and moisture absorbed and retained, so the used insole can be taken out, dried in sunlight and reused, which is economical. Is. On the contrary, it is possible to make a disposable insole by selecting the material of the upper surface member (1) and the material of the moisture permeable paper (3) and minimizing the amount of the batting (4). Not only is this disposable insole comfortable to use, it is extremely hygienic as it is discarded after use.
