Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an insole structure having an outer sole and an insole separately or integrally formed, and more particularly to an insole structure adopted for indoor footwear such as slippers and sandals.

[0002]

[Prior art]

 Various footwear has been proposed for ordinary people to treat or prevent foot diseases such as hallux valgus, athlete's foot, etc. or to exercise their feet through daily life. One of the features of this type of proposal is that four convex portions are formed on the part between the toes of the foot contact surface such as shoes and insoles. For example, in Japanese Utility Model Publication No. 4-23404, Japanese Utility Model Publication No. 6-21406, Japanese Utility Model Publication No. 6-48403, and Registered Utility Model No. 3019362, the projections, thongs, and partition walls that completely separate each toe are convex. Is formed as a part. Further, in Japanese Utility Model Laid-Open No. 7-34702, the projection of the triangular piece is formed as a projection for the purpose of stimulation. Further, in Japanese Utility Model Laid-Open No. 7-30708, a raised portion that fills the depression on the back side of the toes is formed as a convex portion.

[0003]

[Problems to be solved by the device]

 In the projections and the like of the conventionally proposed No. 4-23404, No. 6-21406, No. 6-48403, and No. 3019362 registered utility model, since each toe is completely separated, A protrusion or the like is formed perpendicularly to the entire length of the toes at the height from the to the instep or the height to the toes. For this reason, when putting on footwear, there is a practical problem that the projections and the like interfere with the insertion of the toes, and one must sit down and insert each of the toes between the projections. In particular, indoor shoes such as slippers that are repeatedly worn and taken off are inconvenient and pose a problem. In this respect, according to Japanese Utility Model Laid-Open No. 7-34702, the protrusion is a triangular piece, so it is relatively easy to wear, but when a healthy person wants to casually use it as a preventive measure in daily life, the protrusions etc. are conspicuous. Since it is clearly understood as a therapeutic purpose, it is a problem as indoor footwear for home use. The projections described in each of the above-mentioned public notices are similar in that they are conspicuous. In this respect, the ridge described in Japanese Utility Model Laid-Open No. 7-30708 is relatively inconspicuous, but in order to fill the back side of the toes, each person has different back sides of the toes, so the ridges are slightly different for each person. It has a complicated shape. If this fit is emphasized, it will not be possible for indoor shoes to accommodate everyone. On the other hand, it would be too expensive if a custom-made system was adopted. In addition, if the shape has improved fit, it will come into close contact with the skin of the foot, and this may cause the foot to get uneven. The present invention has been made in consideration of the above problems, and the purpose thereof is that it is easy to put on and take off, the protrusions on the upper surface of the insole are not conspicuous, and generally it can be applied to all soles. An object is to provide an insole structure of footwear that can be manufactured at low cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the insole structure of the footwear according to claim 1 is a synthetic resin insole structure in which four first to fourth protrusions are provided in an inter-toe part. The 1 convex part is provided between the toe and the 2nd toe in a length corresponding to the root to the tip of the toe, and the upper end of the 1st convex part is in contact with the inside of the upper skin. It has a height and is inclined low in the front according to the inclination of the instep, and the middle part of the first convex part is curved below the upper end part corresponding to the side faces of the toe and second toe. The second to fourth convex portions are provided between the second toe of the foot, the third toe of the foot, the fourth toe of the foot, and the little toe of the foot, and the sides are curved inward. It has a trapezoidal cross section, and its height is about 1/2 to 3/4 of that of the adjacent toes, and its length is formed from the base of the adjacent toes to the position of the middle phalanx. . In the insole structure of the second aspect of the present invention, the bases of the trapezoidal cross sections of the second to fourth convex portions are continuous, and the cross sections of the second to fourth convex portions are integrally formed in a corrugated shape. In the insole structure of the footwear according to claim 3, the upper surface of the insole other than the portion where the first to fourth convex portions are arranged is covered with a cloth member. Further, in the insole structure of the footwear according to claim 4, the insole other than the portion where the first to fourth protrusions are arranged has a plurality of protrusions on its upper surface. Further, in the insole structure of the footwear according to claim 5, the first to fourth convex portions randomly provide a plurality of small holes.

[0005]

[Embodiment of device]

 Hereinafter, each embodiment corresponding to the description of the above claims will be described with reference to the drawings as appropriate. In each embodiment, the insole structure according to the present invention will be described using a slipper which is one of indoor shoes. Further, it can be similarly applied to other indoor footwear sandals. FIG. 1 is a partial plan view of a slipper insole of a first embodiment corresponding to claim 1 and claim 3 which is a subordinate concept thereof. Reference numeral 1 in the figure denotes an insole for the right foot, which is paired with an insole for the left foot (not shown), and is molded using urethane foam or polyethylene as a material. The upper surface 1a of the insole 1 for the right foot is the contact surface of the sole of the foot, and at the toe position of the upper surface 1a, the first convex portion 2, the second convex portion 3, the third convex portion 4, and the third convex portion 4 from the toe direction. The four convex portions 5 are sequentially provided. Since each convex portion (2 to 5) is integrally molded or separately molded and attached by an adhesive, it can be manufactured at a very low cost without greatly changing the conventional manufacturing process.

The first convex portion 2 is between the toe 21 and the second toe 22 and is parallel to the toe line 20 of the toe 21 and has a length corresponding to the root to the tip of the toe 22. (See FIG. 2, 19 is the right sole). The thumb line 20 is a line showing the phalanges of the toes 21 and adopts an average human phalange arrangement. The upper end 6 of the first convex portion 2 has a height such that it contacts the inside of the upper 30 and the front end 6a is formed to be lower than the rear end 6b in correspondence with the inclination of the upper 30. (See FIG. 3). Therefore, the height and the inclination of the upper end portion 6 are appropriately changed according to the size and shape of the upper 30 of each size of the slippers to be used. The intermediate portion 7 of the first convex portion 2 is formed to be curved inward below the upper end portion 6 corresponding to the side surface of the toe 21 and the second toe 22 (see FIG. 2A). For example, for an L size slipper, the upper end portion 6 and the bottom portion 8 have a thickness of about 10 mm, and the intermediate portion 7 has a minimum thickness of about 4 to 5 mm. Here, the first convex portion 2 corresponds to the entire length of the toe 21, and the toe 21 is forcibly corrected in an unreasonable state by the curvature of the intermediate portion 7 and an appropriate minimum thickness. Instead, guide to a healthy position in daily life. As a result, it is possible to prevent valgus vulgaris easily.

The second convex portion 3 to the fourth convex portion 5 are provided between each of the second toe 22, the third toe 23, the fourth toe 24, and the little toe 25 of the foot (FIGS. 1 and 2). 2). Each convex portion (3 to 5) is formed such that the side edges (3a to 5a) are curved inward, and the top edge (3b to 5b) is extremely shorter (about several mm) than the bottom edge (3c to 5c). It has a trapezoidal cross section (see FIG. 2A). Further, the cross-sectional height of each convex portion (3 to 5) is about 1/2 to 3/4 of that of the adjacent toes (22 to 24) (see FIG. 2A). On the other hand, the length of each convex portion (3 to 5) is formed from the root of the adjacent toes (22 to 24) to the position of the middle phalanx (22a to 24a) (see FIG. 2B). ). Note that 22b and the like are distal phalanx, and 22c and the like are basal phalanx. As described above, the size of each convex portion (3 to 5) is smaller than the protrusion described in the conventional publication and is not conspicuous. In particular, when the toes enter, they are well hidden by the toes. Here, since the front ends of the protrusions (3 to 5) are located in the middle phalanx, the protrusions (3 to 5) do not contact the ground contact portions of the toes (22 to 25) in an unreasonable state. In addition, since the back of the toes has a large amount of space in the region of the arch, the curved sides (3a to 5a) do not force contact with the back of the toes, and it does not easily become a hindrance when taking in and out the toes. Further, the sectional height of each convex portion (3 to 5) is about 1/2 to 3/4 of that of the toes, which makes it easy to take in and out the toes. Furthermore, the top edges (3b to 5b) have a thickness of several mm and the height is just the contact area between adjacent toes. It can be used effectively. Reflex therapy is an oriental medical treatment, and acupuncture, acupressure, moxibustion, etc. are also known. Yasaburo Yasaburo, editor Anne Hill, Publisher Enterprise Inc.

In the case of the slippers, not only the synthetic resin material molded as described above is used as it is for the insole 1, but a cloth member is used for the portion other than the first convex portion 2 to the fourth convex portion 5 of the upper surface 1a. You can use the outer material. This outer material is a woven or non-woven fabric of various fibers. By using the outer material, the comfort is improved and the moisture absorption is also improved. On the lower side of the insole 1, an outer bottom made of a core material such as polyethylene and a surface material such as polyvinyl chloride is attached or sewn. The insole 1 and the outsole may be integrally formed. Further, on the upper side of the insole 1, various uppers 30 made of a core material such as polyethylene and a surface material of various fibers are attached to form a slipper. Not only ordinary slippers but also so-called Charleston type and boot type are naturally used.

FIG. 4 is a sectional view of the first to fourth protrusions of the insole structure of the second embodiment corresponding to claim 2 and claim 3 of its subordinate concept. In the second embodiment, with respect to the respective convex portions (3 to 5) of the first embodiment, the bottom portions (3c to 5c) are continuously formed to integrally form the bottom portion 9, and the second convex portions 3 to 3 are formed. The four convex portions 5 are formed in a corrugated shape as a whole. Therefore, the bottom portion 9 comes into contact with the arch part of the second toe 22 to the little foot 25, and the sole 19 of the foot is appropriately caught. Therefore, the stability of the sole 19 on the insole 1 is improved, and it becomes easy to put a force on the second toe and the like, and the toe movement can be easily performed in daily life. This toe exercise is very effective for preventing hallux valgus and training for toes. The rest of the configuration is the same as that of the first embodiment, and the effects on the wearability and on the toes are also the same, so a description thereof will be omitted.

Next, a third embodiment corresponding to claim 4 will be described. Although the illustration of the middle bottom of the third embodiment is omitted, it differs from the first and second embodiments in that a plurality of protrusions are formed on the upper surface 1a of the middle bottom other than the protrusions (2 to 5). . The plurality of protrusions are arranged at positions where the so-called foot pots can be stimulated, and give a health effect to the foot and the like synergistically with the effect of the first to fourth protrusions (2 to 5) on the toes. For example, in reflex therapy, if the placement of the convex portion is determined according to the reflex therapy map (see above, illustrated by New Encyclopedia of Human Medicine, p. 63), the effect can be seen on the human body part of the reflex therapy map.

Although a fourth embodiment corresponding to claim 5 is not shown, a configuration in which a plurality of small holes are randomly provided in each of the convex portions (2 to 5) of the above-described first to third embodiments Is. The small holes improve the air permeability and prevent the toes (21 to 25) from coming loose, which is particularly effective in preventing skin diseases such as athlete's foot. The other configurations are the same as those of the first embodiment and the like, and the effects on the wearability and the toes are also the same, so the description thereof will be omitted.
