Description

The present invention relates to a shoe insole on the premise that the outer peripheral edge portion and the arch portion of the shoe insole can be thickened by forming a single sheet using single-sided cardboard paper.

In general, corrugated paper is a double-sided corrugated paper with a corrugated step between two sheets of paper called a liner, and is roughly divided into A, B, and E flutes by corrugated pitch and number of steps. There are many kinds of combinations of them, and various types are mainly used in various industries as cardboard boxes. Single-sided corrugated paper is obtained by removing one side of the liner from the double-sided corrugated paper, and its corrugated surface is usually not often seen. However, the corrugated step is used for packaging materials, small boxes, disposable insoles, etc. because it has a good feel, is easy to bend, and has an interesting design. In particular, the insoles only need to cut out the E flute one-sided corrugated paper into the shape of the sole, giving the soles a refreshing tatami feel, and the paper has water absorption, odor absorption, heat retention, etc. It has features and can be offered at a lower cost than other chemical insoles, but it cannot be used for a long time.

In a single-sided cardboard insole currently on the market, a sheet of E-flute single-sided cardboard is cut into left and right shoe sole molds using special paper printed by Asheet Kobashi Co., Ltd. ( (See Fig. 3 for the design.) Disposable shoe insole “A-SEAT” is distributed throughout the country.

Although the features of the single-sided corrugated paper insoles above have a certain reputation among users, they also stimulate the soles where the acupuncture points of all parts of the human body are concentrated, and back pain There is a need for a shoe insole for preventing O-legs that causes pelvic distortion, knee joint pain, and the like.

The applicant has previously proposed a shoe insole that uses single-sided cardboard to effectively stimulate the arch of the sole of the foot. This insole is a shape in which E flute single-sided corrugated cardboard is connected to the center inside in a pair, and the interstitial part located in the middle is raised to the arch, punched with a punching machine, and the corrugated surface The left and right insoles are wrapped in the arch, and the pair of left and right shoes becomes one insole so that the water absorption is doubled and the durability is doubled or more. Therefore, since the soles of the shoe insole molded in one piece stimulate the arch, the soles of the feet are refreshed and blood circulation is improved. (For example, Patent Document 1)

In addition, a shoe insole for correcting O-legs has a method in which the outside is gradually thickened from the inside, and various types of shoe insoles mainly made of chemical products are commercially available or proposed. As an example, the shoe insole is made up of a spacer that is sandwiched between the upper and lower laying materials and the upper and lower laying materials, and the spacer can be freely attached and removed, and the outer thickness can be adjusted by increasing or decreasing the spacer or replacing it with a different thickness spacer. There is something that made it possible. (For example, Patent Document 2)
JP 7-136004 A JP 2000-254156

The problem to be solved by the above-mentioned problems is to provide a shoe insole in which the outer edge portion and the arch portion are thickened by molding a single-sided cardboard.

In order to solve the above problems, a shoe insole according to claim 1 of the present invention is an E-flute single-sided corrugated paper, and the inner sides of a pair of left and right shoe insoles are connected by ruled lines, and the outer edges of both outer edges are rounded. The bulge part has a hollow part with an arbitrary width along the buttocks from the vicinity of the second joint of the little finger, and the outer edge part that is doubled by the ruled line is connected by the ruled line. Divide the arch part on the center line and connect it with a ruled line to form the left and right outer edges on the left and right insoles with the ruled line, and then fold it back. Fold it back with the insole step on the surface. In this series of steps, the outer edge part and the arch part that folds over the left and right shoe insoles, and the left and right shoe insoles can be temporarily fixed with an adhesive, increasing the product value and facilitating insertion into the shoe. Become.

A shoe insole according to claim 2 is the shoe insole according to claim 1, wherein an easily cut-off line corresponding to a specific size of the shoe insole is provided in the heel portion.

A shoe insole according to a third aspect of the present invention is the shoe insole according to the first or second aspect, wherein a crushing line for crushing the step is inserted into the corrugated step of the single-sided corrugated paper so as to cross the step.

The insole of the present invention can be adapted to the O-leg by providing a thick outer edge portion on the outside of the insole with a single-sided corrugated paper, so that it can prevent knee joint displacement, pelvic opening, When walking, the weight shift from the heel to the arch, the little finger, and the thumb is reliably received in a good rhythm, so you can experience the unexperienced sense of walking by grabbing the ground with your entire sole. Accordingly, the weight does not escape to the outside, and the consciousness is always inward from the thigh to the knee, so the O-leg can be corrected naturally only by walking. Further, by thickening the arch portion of the insole, the arch is effectively stimulated, so that blood circulation is improved and there is a refreshing feeling, and various health effects that could not be obtained conventionally can be expected.

Conventional insoles are supposed to be used for a certain period of time, and the various functions added have characteristics such as hygiene and health, but the functions tend to gradually decline. There is no low price.

The E flute single-sided corrugated paper used in the present invention can be mass-produced in a corrugated cardboard manufacturing plant, and the insole can be formed and assembled continuously by a machine. Moreover, since it is paper, it can be easily processed with a scissors, so that it can be used by devising it to fit each leg. However, the durability cannot be used for a long time due to the paper, but on the other hand, if it is replaced sooner depending on the usage condition, the inside of the shoe can always be kept clean.

Part of the inner side of the pair of left and right shoe insoles with single-sided corrugated paper, forming outer edge parts that can be folded and folded along the outer periphery of the shoe insole from the second finger joint to the vicinity of the heel on both outer sides, Further, the common portion of the lower surface of the inner connecting portion is folded back to the left and right shoe insole arch portions to form the arch portion, and is folded back with the step as the surface.

The size of the insole is usually set every 0.5 cm in the range of 23 cm to 27 cm. In the present invention, since the outer edge portion along the outer periphery of the insole is formed, it is desirable to manufacture each size. However, if the size is increased up to 0.5 cm, the number of types increases. Therefore, the 0.5 cm unit is shared by providing a cutting line in the heel portion.

Embodiments of the present invention will be described below with reference to the drawings. The single-sided cardboard used for the shoe insole has a flat back and corrugated front. In addition, single-sided corrugated paper is usually manufactured with A, B, E flute at the step number and height per 30 cm, but this insole is E flute (90-100 per 30 cm step height, 1.1-1 step height) .3 mm). FIG. 1 is a plan view of the back surface of a shoe insole 1 with a perforation line of a 0.5 cm cut line 7 for size adjustment, and FIG. 2 is a perspective view of the shoe insole according to the present invention during assembly. FIG. Using a single-sided corrugated paper, the outer edge 2 along the outer periphery of the pair of left and right shoe insoles 1 with a part of the inner side connected with the ruled line 4 is connected with the ruled line 5 and folded back on the shoe insole 1 with the ruled line 5 Fold at the ruled line 6. Next, an arch portion 3 having an arbitrary width is divided into a center line on the upper and lower center portions of the lower connecting surfaces of the left and right insoles, and folded on the left and right shoe insoles 1 along a ruled line 7. Fold it over to make it a half-sole insole.

In the above, if there is not enough room in the shoe, such as leather shoes, high heels, etc., if the connecting part of the ruled line 4 is separated and each of them is used as an insole on the left and right sides, the thickness becomes half and it can be used as one foot without feeling cramped. It is also economical.

In FIG. 1, if the size of the insole is classified into a free size or S, M, L, etc., it is convenient because it can be shared. This shoe insole is difficult to adjust at the heel or toe portion due to the relationship of the outer edge 2, but 0.5 cm at the heel is within the allowable range of adjustment. In this case, it is better to cut off the lower end of the outer edge 2 together. In addition, when diverting a large size to a small size, considering the overall balance, the top may be cut off with a scissors.

FIG. 3 is a plan view of the surface of an insole formed by assembling and assembling a single-sided corrugated cardboard sheet 9 in parallel. In this state, the cardboard image is strong during use and the crushing of the step 9 is conspicuous and gives an ordinary feeling. FIG. 4 shows a single-sided corrugated paper sheet that has been molded and assembled so as to cross a crushing line 10 that crushes the step 9. By inserting the crush line 10, the step 9 is strengthened and the comfort and durability are also increased. FIG. 5 shows a sheet in which the crushing line 10 is placed in the step 9 and is formed and assembled obliquely. This shape is excellent in design, but the yield of the sheet is deteriorated at the time of molding. In addition, formation of a crush line has the method of putting simultaneously with a shaping | molding roller at the time of shaping | molding into a corrugated-cardboard sheet | seat beforehand.

6 is a cross-sectional view taken along the line AA in FIG. Since the outer peripheral edge 2 is sandwiched along the edge of the outer periphery of the insole, the outer side is thicker and the inner side is thinner. If the thickness of one sheet is 1.3 mm, the outside of the shoe insole is 1.3 mm × 6 = 7.8 mm and the inside is 1.3 mm × 2 = 2.6 mm. 7 is a cross-sectional view of the arch portion of FIG. 5 taken along the line BB. Since there is an arch portion 3 on the inside, 1.3 mm × 4 = 5.2 mm. However, when walking, the entire space in FIGS. 6 and 7 is in close contact with the pressure of the soles, and the step height is gradually compressed to a thickness of about 80% of the original.

In the above, since the state of the sole of the foot is different, a shoe insole suitable for each is desirable. Since the insole of the present invention uses corrugated paper on one side, it can be easily processed by using a heel, so unnecessary parts are removed with the feel of the soles of the feet, and necessary parts are familiar paperboard, cardboard, etc. If you use, you will be able to use a shoe insole that is almost custom made.

The present invention enables continuous production of E flute single-sided corrugated cardboard with a plurality of shoe insoles with a flat-blade mold with cutting blades embedded in a punching machine, and assembly is automatically folded and folded by the machine. Because it can be shaped, it can be produced at low cost.

When using a shoe insole, the soles of the user's feet are very different, and it is quite difficult to select a shoe insole that suits you due to the burden on the foot due to body shape, past medical history, etc. from commercial products It can be said. Therefore, this shoe insole is basically thickening the outside and stimulating the O-foot correction and the arch part, but the material is a single-sided cardboard, and the unnecessary part is removed depending on each person's condition. In addition, it is possible to use my insole with reinforcement using paper at hand. As for durability, because it is corrugated paper, it is weak against moisture, humidity, and strong pressure, so it is necessary to replace it periodically depending on the state of use. Therefore, there is an advantage that the shoes can always be kept clean by replacing them regularly, and since it is paper, there is no problem with disposal.

Recently, walking that can be performed easily as a method for maintaining health has become the mainstream, and there are many elderly people in particular. If you use this insole during walking, you can prevent back pain, knee joint pain, and arrhythmia by effectively stimulating the soles with points on all parts of the human body and promoting blood circulation, and expect a diet effect. Furthermore, regular replacement always keeps the shoes clean, so you can eliminate the problems of athlete's foot, oily feet, and foul odors. However, it is necessary to reduce the image that it is made of corrugated cardboard. As a solution, it is possible to use special paper such as printed paper and antibacterial paper with a pattern on the corrugated corrugated corrugated board. It is done.

The 21st century preventive medicine is said to have poor blood circulation due to lack of exercise, but if the insoles of this shoe are proven in sports medicine and used by many people, social security expenses will increase every year in the future. I believe that it can greatly contribute to restraint.

It is a perspective view in the middle of the assembly of a shoe insole. It is a top view of the back surface of a shoe insole. It is the top view which shape | molded and assembled | assembled with the step | line | column of the shoe insole in parallel. It is the top view which put the crushing line in the step of the shoe insole, formed and assembled.
