Abstract

PROBLEM TO BE SOLVED: To provide an underlay for a shoe insole, which is molded of a shaped plate fin-worked from a copper alloy thin plate into a half-shoe bottom having a cut tip, so that a clean and healthy sole is always kept by the bactericidal action of copper and with the air-permeability of the fin work.SOLUTION: A molding plate, which has been subjected to a corrugated fin treatment having continuous corrugation or an offset fin treatment by using a thin plate of one kind of various copper group alloys, is molded into one pair of right and left sole molds 1 which have their portions near the roots cut at the leading ends of the whole sole shapes from the thumbs to the fifth fingers, and outer frames of chemical products having elasticity are provided therearound.

Description

In the present invention, a thin plate made of a copper-based alloy having a bactericidal action is formed into a half-sole shape by cutting the tip of a pair of left and right shoe sole shapes from a molded plate obtained by fin processing (corrugated or offset, hereinafter omitted) having excellent air permeability. The present invention relates to a shoe insole that is molded and used mainly under a normal shoe insole.

The purpose of using a shoe insole is to keep the inside of the shoe clean and keep the soles healthy. In order to achieve this purpose, various materials (synthetic resin, synthetic rubber) have effects such as deodorization, deodorization, antibacterial, moisture absorption, anti-swelling, breathability, cushioning, refreshing feeling, massage effect, sole stimulation, etc. , Cotton, hemp, non-woven fabric, single-sided corrugated cardboard, etc.) have been developed, and many types of insoles have been developed and are commercially available. These insoles are roughly classified into continuous use type and disposable type when classified by usage. The continuous use type is durable and can be used for a long time, but the various effects that were originally provided gradually disappear with the number of days and the inside of the shoe becomes unclean. As a countermeasure, it is recommended to prepare two sets and use them alternately. However, there is a limit to the period, and it is often used for a long time in a filthy state. The disposable type uses cloth, non-woven fabric, synthetic resin sheets, single-sided cardboard sheets, etc., which are inexpensive and easy to manufacture, and can be kept clean if the shoes are replaced regularly depending on the usage conditions. It is limited and inferior in strength, so it must be replaced frequently and is troublesome. In addition, the design is simple and inferior to the continuous use type. In any case, the various insoles currently on the market have their merits and demerits. What has been most sought after for insoles is to remove malodors and reliably prevent the occurrence of troublesome athlete's foot.

Summarizing the explanation of “What is the trace metal action of copper?” By the Japan Copper Center, metals such as copper and silver have an effect called trace metal action, and they exhibit surprising bactericidal action even in a small amount . A very small amount of metal ions dissolved in water or the like suppresses the activity of sterilizers, and the same effect is observed in gold and silver in addition to copper. Although the exact mechanism is not known, it is the same as that that causes toxic symptoms in humans and animals, and copper ions accumulated in bacteria and microorganisms exceeding the allowable amount interfere with the action of various enzymes. Recently, the bactericidal effect of copper on the environmental surface has attracted attention, and MRSA (methicillin-resistant Staphylococcus aureus) and MDRP (multidrug-resistant Pseudomonas aeruginosa) that cause nosocomial infections are killed by direct contact with copper. Other examples of copper trace metal action include pesticide Bordeaux, copper triangle corners and drainage garbage catchers for household use, 10-yen coins in vases for long-lasting cut flowers, bathing hot water It has been applied to various fields such as bath goods that keeps you clean and hygienic, kitchen sponge coated with copper fine particles, purification of pools and water reservoirs, socks and insoles, and so on.

Several examples of shoe insoles for preventing athlete's foot by using a copper plate for shoe insoles have been proposed. One example is the antibacterial and antibacterial action, in which a plurality of copper plate pieces are interposed between the overlay material and the underlay material that match the shape of the sole of the foot, and multiple shiatsu holes are formed in the overlay material to expose the copper plate and adhere It is a shoe insole that effectively provides anti-perspirant action and does not stain the sole of the foot due to patina. (Patent Document 1) In two examples, protrusions are provided on the surface of a thin flat insole made of a copper-based alloy, the cross-sectional shape is corrugated, and any hole penetrating from the front surface to the back surface is formed in a shoe sole shape In addition, this is a shoe insole that provides the deodorizing and sterilizing effects of the copper alloy, as well as surface protrusions, undulations, finger pressure on the soles through the through holes, irritation, and breathability. (Patent Document 2) Three examples are shoe insoles for prevention of athlete's foot using a sterilizing power of copper, in which a large number of air holes are provided on a thin copper plate and a non-slip film is adhered thereon. (Patent Document 3)

The inventor first used single-sided corrugated paper, and on the premise of disposable, connected the inside of a pair of left and right shoe soles with the tip cut along the base of each toe with a fold line, and raised the arch and outer periphery Half shoe insole (Patent Document 4) that wraps in the back left and right shoe sole shape and the insole that folds the interstitial part of the center of the pair of left and right shoe soles and folds it on the arch (Patent Document) 5) is proposed. Each step has a surface and a arch on the sole of the foot, and the paper has odor absorption and moisture absorption that can be provided at low cost.

The problem to be solved by the invention is to provide an insole for a shoe insole that can keep the inside of the shoe clean, use materials that are effective against bad odors, athlete's foot, etc., and solve various foot problems when wearing shoes It is to be.

The means for solving the above problems is to use a thin plate of various copper-based alloys, and to form a corrugated fin-processed molded plate with concavities and convexities. A pair of cut left and right half shoe soles are molded. The main copper-based alloys are brass (brass) plates (copper and zinc), phosphor bronze plates (copper and tin), beryllium copper plates (copper and beryllium), etc., which are stronger and cheaper than pure copper plates, respectively. Because of its excellent wear resistance and fatigue resistance, select from these. Since the insole on the upper surface is in a state of two layers, it is not suitable to be thick. When used alone, it is desirable to provide an outer frame of a chemical product (synthetic resin, silicon rubber, etc.) having elasticity.

Copper has excellent sterilizing power, so fin processing and underlaying of the shoe insole will improve the breathability in the shoe, increase the surface area from the flat shape, and generate a large amount of copper ions in proportion. So sterilizing power is also increased. In addition, the copper alloy plate gradually changes along the shape of the sole of the foot with the passage of use time and can be used without a sense of incongruity. If it is used as a commercial insole inlay, an unprecedented insole effect can be obtained by a synergistic effect of each characteristic. When choosing shoes, if you insert a shoe insole into the shoe and select a shoe that matches your foot with the shoe, you can walk comfortably every day and practice the health practice of walking.

The insole of the copper insole with fins processed is three-dimensionally processed, so the thickness is slightly higher than that of ordinary shoe insoles, so the tip of the shoe becomes cramped in all soles, leather shoes, sneakers, high heels, etc. Can not be used. Therefore, if the front of the entire shoe sole shape is a half shape that is cut at the base of five fingers, the feeling of cramping can be eliminated and the width of the heel portion can be set to the width of the entire shoe size (between 22 cm and 28 cm. If the spacing is 5 cm, it is not necessary to align 13 sizes). For example, if the S size is 22 cm to 23.5 cm, the M size is 24 cm to 25.5 cm, and the L size is 26 cm to 28 cm, the three sizes can be handled and the boundary size may be selected. In this case, when inserted into the shoe, it is not fixed unlike the conventional insole, but if the heel part of the insole of the insole is aligned to the back of the shoe, the upper insole will penetrate into the uneven surface When in the state, the tip of the insole is pushed to the rear of the shoe at the base of the toe as it walks, so it can be used in a stable state. Further, the half shape with the toe cut cuts the toe, and the toe feels free to move and grabs the ground when walking, giving vitality to the entire sole of the foot.

Depending on the condition of the soles, the insole of the insole can be used alone. In this case, the shape is irregular in the molded state, and especially when the step on the toe part directly hits the sole of the foot, it may feel pain, so there is no chemical product (synthetic resin, silicone rubber, etc.) around it. This can be prevented by providing a frame. Moreover, the pattern of the fin processing surface is excellent in aesthetics, and since the copper ions and the uneven surface act directly on the sole of the foot, it is possible to experience a feeling that has never existed before.

It is a top view of the half shoe sole shape of corrugated fin processing with the insole of a shoe insole. It is a top view of the half shoe sole shape of offset fin processing in the insole of a shoe insole. FIG. 6 is a plan view of a half-sole shape in which a chemical product frame is provided around a shoe insole. It is sectional drawing which mounted the other insole on the insole of the insole.

Using a copper alloy thin plate with a fin processing plate that exhibits excellent air permeability, a half-sole shape with a pair of left and right five fingers cut is molded, and has elasticity depending on the state of use A frame made of chemical products is placed around.

Embodiments of the present invention will be described below with reference to the drawings. Fin processing is a product that can form three-dimensional processing of uneven surfaces at regular intervals with a press machine, such as copper, aluminum, stainless steel, and iron. Various products that require air permeability (oil cooler, heat exchange) It is a well-known shape product that is used in applications such as containers, filters, air conditioners, cold plates, etc. 1A and 1B are a plan view and a cross-sectional view taken along line AA of a half-sole shape with corrugated fins in the insole of a shoe insole according to the present invention. Corrugated fin processing is a shape where concavities and convexities are connected, and it is easy to process and has excellent pressure resistance, so it is difficult to deform even if it is used for a long time. The corrugated finned half-sole shape 1 should be as thin as possible, but it should not be deformed or broken in the shoe during use. As a standard, if the height is 3 mm or less, most shoes can be handled. Therefore, the copper-based alloy thin plate under these conditions is desirably 0.3 mm or less, and it must be a formed plate having a height and a pitch that can withstand long-term use. In this figure, the uneven surface is horizontal, but it may be vertical.

FIG. 2 is a plan view and a BB cross-sectional view of a half-sole shape with an offset fin processed on the insole of a shoe insole. The offset fin processing is one in which irregularities are alternately connected, and the offset fin processed half-sole shape 2 has a more complicated shape than the corrugated fin-processed half-sole shape 1, and has good ventilation and good design. When used for a long time, the machined surface is likely to break. As countermeasures, it can be easily handled by examining the material, height, and pitch.

FIG. 3 is a plan view and a CC cross-sectional view of a half-sole shape in which a chemical product frame is provided around a shoe insole. Burr is likely to occur around the molded insole, but when used as an undersole, there is no problem because the foot is not touched directly. When used alone, there is a possibility of pain at the tip, and a chemical product frame 3 is provided around as a countermeasure. However, if the thickness of the molding plate is reduced, the periphery is also crushed during molding, and if the burrs are not noticeable, the soles of the feet become familiar, so the frame 3 need not be provided.

FIG. 4 is a sectional view in which another insole is placed on the insole. In this figure, a shoe insole 4 (refer to Patent Document 5) made of corrugated cardboard that is proposed and commercialized by the present inventor and stimulates the arch is placed. The toes are covered with a shoe insole so they won't get dirty. Corrugated cardboard has excellent moisture absorption and odor absorption, and the corrugation stimulates the entire sole of the foot and the bulge of the arch acts effectively. Therefore, copper ions generated from the insole of the insole sterilize, and the voids in the fin processing improve the ventilation in the shoe, so the effect that was not obtained with conventional insole due to the synergistic effect of each other Can be expected. Various other commercially available shoe insoles can also be used by placing them on the insole of the shoe insole, so that the respective characteristics are exhibited and good results are obtained.

The shoe insole of the present invention utilizes a molded plate that can be continuously processed in order to maximize the bactericidal action of copper. By putting it in, it has some synergistic effects such as deodorization, deodorization, antibacterial, moisture absorption, stuffiness prevention, ventilation, cushion, refreshing feeling, massage effect, sole stimulation etc. Demonstrate. In particular, there is a high possibility of a new form that can cope with athlete's foot that could not be solved by conventional shoe insoles.

The sole of the foot is said to be the second heart and is dotted with many points. In everyday life, shoes are used every day, but many people are indifferent about shoes and health. Ideally, it ’s best to wear shoes that fit your feet, but custom-made shoes are expensive and no one can wear them. If this is the case, the foot will be matched to the shoe, but in this case it can be easily done by adjusting with the shoe insole. Good results can be obtained when used together with the insole.

Moderate exercise is necessary to maintain a healthy body, and walking, jogging, etc. can usually be performed easily. In this case, there is a great difference in health between walking with ordinary shoes without insoles and walking with insoles that can stimulate the soles of the feet in the shoes. The inventor made a trial by inserting a shoe insole made of corrugated cardboard and stimulated on the insole of the shoe insole. As a result, the inside of the shoe was more refreshing than the case of using only a cardboard shoe insole, the occurrence of athlete's foot did not occur, and the period of use increased more than 10 times. Therefore, it is considered that the same result can be obtained even when other various insoles are inserted. In addition, since the toes move within the shoe, the user feels that he is grasping the ground during walking. This feeling is obtained with clogs, sandals, etc., but it can be said that there is no use at present, and it can be experienced simply by inserting a shoe insole into the shoe. In addition, the idea of putting an underlay further under the insole is rare, and verification in terms of efficacy is yet to be done, but it can be expected to have a great effect on the prevention of athlete's foot by sterilization, antibacterial and deodorizing action in the shoe, I am confident that it will grow into a revolutionary product that will please people who have problems with their feet.
