Description

  INDUSTRIAL APPLICABILITY The present invention is effective in preventing or preventing progression of hallux valgus, flat feet, etc., and tailoring an insole for footwear or an insole for footwear suitable for a user's foot based on foot-related information such as sole shape information. The present invention relates to an insole for footwear that can be easily manufactured by the manufacturing method, an auxiliary device for manufacturing the insole, and a sole shape collecting means.

  Conventionally, as insoles for footwear for preventing hallux valgus, for example, “footwear for inversion hallux and shoe insoles” (Patent Document 1), “shoe insole” (Patent Document 2), and “multifunctional shoe insoles” (Patent Document) 3) is disclosed. Although each of the above documents discloses a shoe insole in which each part of the sole is defined, provided with uneven portions, provided with a bulge, or an elastic pad is attached, the part of the sole is infinitely different for each person. Depending on the degree of the hallux valgus or flat feet, etc., the type of pad and the position of the pad are different, and if you make a mistake, it will cause pain and difficulty in walking, or the expected preventive effect such as hallux valgus will not be expected. However, there was a problem that the body was adversely affected.

  In order to solve the above-mentioned problems, there is a demand for manufacturing an insole corresponding to each person by collecting individual footprints. For example, a “shoe insole processing method” (Patent Document 4) is disclosed as a foot shape collection device. Although the foot shape measuring device has an advantage that the shape of the sole can be collected in three dimensions, the device is It is complicated and is not suitable for transporting the device to a remote location and collecting the sole shape. Further, according to the method disclosed in “a method for producing a shoe shape of a full-order made shoe and a foot collector used therefor” (Patent Document 5), a softened thermoplastic resin is stretched on the foot and molded. However, there is a problem that it takes time and effort to collect molds and requires habituation and skill. In addition, although the foot printer disclosed in “Pattern Collection Method and Mold Collection Method” (Patent Document 6) is easier to use than the device disclosed in Patent Document 4, the device is used by transferring the device to a remote place. However, there are drawbacks that are cumbersome and lack easy.

And by using the above-mentioned production assisting device such as an insole, there is an effect of accurately and economically producing an insole for footwear or an insole for footwear suitable for a user's foot.

  Next, the best mode for carrying out the present invention (hereinafter referred to as “embodiment of the present invention”) will be described with reference to the drawings. However, the present invention is not limited by the embodiment of the present invention. FIG. 1 is a flowchart showing an insole manufacturing process according to an embodiment of the present invention, FIG. 2 is a block diagram showing an insole manufacturing assisting device according to an embodiment of the present invention, and FIG. FIG. 4 is an explanatory view exemplifying image data of the insole body, the raised pad, and the mounting position of the raised pad based on the sole shape information collected by the sole shape collecting means according to the embodiment of the present invention. FIG. 5 is a view illustrating a raised pad, and FIG. 5 is a view in which a predetermined raised pad is attached to the insole body.

  The shoes that many people currently wear are not necessarily suitable for their feet, but rather the emphasis on the appearance, by wearing shoes that do not fit the feet such as high heels and extreme tapered shoes for a long time, Deformation of the feet causes abnormalities in the feet such as hallux valgus, flat feet and open feet. Hallux valgus is a progressive deformity in which the thumb (first finger) bends in the direction of the little finger (fifth finger) and the base of the thumb (the metatarsal bone head) protrudes. Is a disease. Even with normal feet, the thumb is bent by 5 to 10 degrees. However, in the case of hallux valgus, the turning angle of 11 to 19 degrees is mild, and 20 degrees or more is required.

  As the symptom progresses, the thumb may ride on the next finger, dislocation and bend completely, and the protruding part may hit the shoe and cause pain. In addition, a foot with a flat heel and a horizontal arch that collapses the sole and arch of the sole, which naturally acts as a spring, is called an open leg. It is said that the hallux valgus often starts with an open leg, and the hallux valgus starts with an open leg. A flat foot is a foot whose vertical arch on the arch is low and the sole of the foot is flat. On the other hand, in the hallux valgus, the lateral arch at the base of the foot is lowered, and the width of this portion is widened.

  The cause of hallux valgus is a decrease in the lateral arch. Thus, it is already known to put a raised pad on the arch and raise it. However, the height and mounting position of the raised pad differ depending on the degree of deformation of the foot. Usually, the mounting position and height are determined by collecting the sole shape and examining the pressure on the sole. It depends largely on intuition and experience.

  Therefore, the present inventor ranks the degree of foot deformation from the sole shape based on many years of experience, and correlates the degree of foot deformation with the optimal height of the raised pad and the mounting position. And insole information. Table 1 shows a foot / insole information table. According to Table 1, as the foot-related information, the degree of deformation of the thumb (first finger) is, for example, normal (5 to 10 degrees), mild (11 to 19 degrees), caution (20 degrees or more) According to the degree of deformation of the thumb, the insole information is normal when the height of the raised pad is 18 to 11 mm, the mounting position is 1 to 3 mm, and in the case of mildness, the height of the raised pad When the height is 10 to 7 mm, the mounting position is 4 to 6 mm, and the height of the raised pad is 6 to 3 mm and the mounting position is 7 to 9 mm, the foot related information and the insole information are associated with each other. Thus, the information is stored in the foot / sole information table of the storage area of the computer, and the optimum information is selected from the insole information by the selection means.

  Among the raised pads used in the present embodiment, the raised pad 13a (HA) for holding the horizontal arch is a plan view as shown in FIGS. 4 (a) and 4 (b), one end is circular, and the other end is a cusp. A gentle ridge is formed, with a circular shape and a substantially central part of the circle. In Table 1, the height of the raised pad refers to the distance from the ground point to the apex of the raised pad. Further, as shown in FIG. 3, the mounting position of the raised pad is such that the second finger and the center of the heel are connected by a straight line (A), and then the mother sphere and the small sphere are connected by a straight line (B). The distance from the intersection of both straight lines (A) and (B) to the circular tip of the raised pad shall be said. As shown in Table 1, the height of the raised pad and the mounting position are closely related to the symptoms of hallux valgus. In normal cases, the height of the raised pad is relatively high, and the mounting position is moved forward. As the symptom progresses, it is preferable to lower the height of the raised pad and install it closer to the rear.

  As shown in FIGS. 4 (c) and 4 (d), the vertical arch holding raised pad 13 b (VA) is formed in a shape substantially comparable to the space formed between the ground contact surface of the foot and the arch. That is, in a plan view, the shape is a substantially lip shape that is closed up and down and is gently raised in the longitudinal direction. As shown in Table 1, according to the lateral arch holding raised pad 13a (HA), the level of the flat foot, that is, the size of the area of the sole arch space is ranked large, medium, small, According to this rank, the heights of the ridges are associated with each other as 25 to 17 mm, 16 to 10 mm, and 9 to 5 mm, and stored in the foot / sole information table. The attachment position may be set so as to be attached at a position corresponding to the position of the sole arch. The degree of the hallux valgus or flat foot is determined by visual observation from the sole shape, or by measuring the bending angle of the thumb or the area of the arch, and inputting it as foot related information by the input means, From the graphic information, the central processing unit may calculate the bending angle of the thumb and the area of the arch based on known means, and these numerical values may be used as the user's foot-related information.

  Examples of the association between the foot related information and the insole information include, in addition to the above, the association between the size of the foot and the size of the insole for footwear, and the type of shoes such as shoes for sneakers / casual shoes or pumps / business shoes. There is an association between the type of the insole and the shape of the insole body, an association between the frequency of sports or other walking and the height or mounting position of the raised pad of the insole for footwear. Among these additional information, the frequency of sports or other walking is converted into a coefficient and associated with the height or mounting position of the raised pad, for example, 1.0 when the frequency is low and 1. 05, the case of large is defined as 1.10, and the mounting position is determined by multiplying the mounting position of the raised pad determined from the degree of deformation of the thumb by the coefficient, and the height of the raised pad is divided by the coefficient. It is preferable to incorporate it into the program so as to be reflected in the information. In addition to this, as many as possible factors affecting the insole for footwear are related as much as possible by factorization and stored in the foot / sole insole information table. This is more preferable.

  As shown in FIG. 2, the insole manufacturing assisting device according to the embodiment of the present invention selects a control program 1a for controlling a computer and insole information suitable for the user's foot from the table. A storage device 1 for storing a selection program 1b and an image creation program 1c for creating an image representing a predetermined raised pad at a predetermined position in a predetermined insole body based on the selected insole information; A storage device 2 for storing the foot / sole insole information table 2a for associating the foot related information and the insole information with each other and storing them in a table format, the central processing unit 3, and the user's foot related information are input. Input means 4, and output means 5 for displaying image data or insole information.

  Next, the sole shape collecting means according to the embodiment of the present invention will be described. A paper color sheet containing a color former and a substance that develops color by reacting with the color former is used in combination. Examples of the color former include liquids containing iron ions such as ferrous ions or ferric ions, and substances that react with the color former include tannic acids. A paper with a relatively water resistance, which is a paper sheet, is immersed in a tannic acid solution in advance to contain tannic acid, and the color developing agents such as ferrous sulfate, ferric sulfate, and ferric chloride Apply a solution containing iron ions to the soles of the feet, quickly put the feet on this paper, get up and put weight on the feet, and then remove the feet from the paper, the iron ions and tannic acid react with each other. As a result, blue to black tannin iron is produced, and a sole shape is formed on the contact surface between the paper and the foot. As examples of such a color former and a color developing sheet, a color developing solution and a color paper manufactured by Pilot Ink are commercially available.

  In addition to the combination of tannic acid and iron ions, a colorless leuco dye (Lewis base) and a leuco dye developer (Lewis acid) may be used in combination. A leuco dye is a kind of vat dye, and a leuco body is produced and colored by an oxidation-reduction reaction. An example of the developer is a bisphenol A solution. The paper is dipped in this solution and dried to form colored paper, and a colorless leuco dye is applied to the sole as a color former, and the sole shape is collected in the same manner as described above.

  By using a combination of the above color former and a paper sheet containing a substance that develops color by reacting with this color former, for example, compared with a method of collecting the sole shape by applying ink to the sole. Not only is it freed from the hassle of washing away dirt, but also when you put your weight on your feet and collect the sole shape, the difference between the part that is weighted and the part that is not covered appears relatively clearly There is a clue to guess the pressure applied to the sole when doing so, and there is an advantage that more accurate and advanced information can be obtained as insole information.

  With reference to the flowchart shown in FIG. 1, the insole manufacturing process which concerns on embodiment of this invention is demonstrated. First, when the foot-related information and the insole information are associated with each other in advance by the input means and input to the computer (manufacturing assist device such as the insole) in step S1, one piece of foot-related information and insole information is 1 A record is stored in the foot / insole information table 2a of the storage device 2 in a table format. Next, when the sole shape information and other foot related information of the insole user for footwear are input in step S2, the user is selected from the foot related information in the table according to the selection program 1b in step S3. The data matching the foot related information is searched, and the insole information associated with the foot related information is selected. Next, in step S4, based on the insole information, the insole body closest to the sole shape of the insole user is selected from the insole body of a predetermined size and shape by the selection means, and the image is selected. According to the creation program 1c, the contour line and the contour line of the raised pad are created as image data around the sole shape of the insole user, and the insole data or image data is output in step S5. The above is the operation (step S6) related to the manufacturing support device such as the insole.

  Since the insole 10 for footwear can be easily manufactured by the step S7 based on the insole information on the insole body, the raised pad, and the mounting position of the raised pad obtained by the manufacturing support device such as the insole. is there. The method of manufacturing the insole for footwear is not particularly limited. For example, the mounting position of the raised pad is displayed on a predetermined insole body by linking the manufacturing support device such as the insole with an XY plotter or a printer. You may let them. An insole for footwear is completed by attaching a raised pad having a predetermined height obtained by a manufacturing auxiliary device such as an insole to the mounting position of the raised pad. The material for the insole for footwear is not particularly limited, and a commercially available product may be used.

  Next, Example 1 will be described with reference to the drawings. First, the sole shape is collected according to the sole shape collecting means using the color developing liquid and color paper made by the pilot ink company. This sole shape is read by an image scanner and input to a computer. At the same time, the foot-related information such as the degree of deformation of the big toe, the area of the arch, the size of the foot, the type of shoes, etc. is input by the input means. Based on the input foot-related information, the insole manufacturing assisting device selects the insole body that matches the size of the user's foot and the type of shoe, and the contour line and foot of the insole body are displayed on the computer monitor. A raised pad corresponding to the degree of thumb deformation and the area of the arch is displayed at a predetermined position. When the selected insole body is set at a predetermined position of the plotter, the mounting position of the raised pad is plotted on the back surface of the insole body by the plotter.

  Next, a predetermined raised pad selected by a manufacturing auxiliary device such as an insole is processed to a predetermined height at the mounting position on the back surface of the insole body, and is pasted and pasted. In this embodiment, as shown in FIG. 5, the insole body 11 has a two-layer structure in which a back side is formed by laminating cloths having raised or trapped surfaces on a polyethylene foam surface, and a mold having a predetermined shape is attached. A hot press is used to form a shape that slightly raises both sides from the fence to the arch. The heel part 15 was affixed to the heel. Needless to say, the structure of the insole body and the mounting location of the raised pad can be changed according to the conditions of the user. The material of the raised pad is preferably a sponge (closed-cell) material such as rubber or urethane that is elastic to some extent. Further, in this embodiment, the raised pad is attached to the back side of the insole body, but it may be attached to the front surface or between the front surface layer and the back surface layer.

  In the first embodiment, instead of plotting the mounting position of the raised pad on the back surface of the insole body by the plotter, the mounting position of the raised pad is printed on the transfer sheet by the printer, and this is printed on the back surface of the insole body. Example 1 is the same as the example 1 except that the transfer is performed. However, it is necessary to consider so that the position after transfer is not reversed. Further, the mounting position of the raised pad on the insole body based on the sole shape and other foot related information collected by the sole shape collecting means according to the embodiment of the present invention without using the insole manufacturing assisting device An insole for footwear, in which a bulge pad is attached, with a direct indication of the above, is also included in the scope of the present invention.

  Further, the raised pad may be attached to the surface of the insole body instead of the back surface of the insole body. Furthermore, although the description so far has mainly focused on the insole for footwear, the present invention is not limited to the insole for footwear, and as long as it matches the gist of the present invention, the insole for footwear. Such an insole for footwear is also included in the scope of the present invention.

  The insole for footwear or the insole for footwear according to the present invention, the production assisting device such as the insole, and the sole shape collecting means are effective in preventing or preventing progression of hallux valgus, flat feet, etc., and fit the user's foot The insole for footwear is extremely useful because it can be easily manufactured based on foot-related information such as sole shape information.
