Abstract

PROBLEM TO BE SOLVED: To provide a sockliner eliminating oppression to toes because a toe part is all covered by an upper leather by solving the problem that although a sockliner for a shoe aiming load reduction to a foot effects cushioning effect by thickening the same, the inside of the shoe is tight by the sockliner when using the sockliner in the shoe, on the contrary adverse effect is imparted to the foot.SOLUTION: In the sockliner for the shoe, the toe side front fringe 0504 of the cushioning material 0503 is located corresponding to an area sandwiched by the line connecting bone bottoms of respective proximal phalanges from the bone bottom of the first proximal phalange 0202 to the bone bottom of the fifth proximal phalange 0206 of the foot put into the shoe and the line connecting the middles of the respective proximal phalanges from the middle of the first proximal phalange 0202 to the middle of the fifth proximal phalange 0206 as the part not making a user feel the difference in thickness.

Description

  The present invention relates to a shoe insole and an insole structure used in a shoe.

  Usually, in human walking, three arches on the sole, that is, an inner longitudinal arch from the radius to the first metatarsal head, an outer longitudinal arch from the radius to the fifth metatarsal head, the first middle The landing impact pressure due to the weight load is absorbed by the lateral arch from the head of the foot to the head of the fifth metatarsal. That is, the three points of the radius, the first metatarsal head, and the fifth metatarsal head are the ground contact points.

  Conventionally, various insoles for shoes have been proposed for the purpose of reducing the impact load on the soles during walking as described above, and preventing or ameliorating each symptom due to the collapse of the foot skeleton. . For example, there is an insole made of a cushioning material for the purpose of absorbing an impact on the sole when landing. In order to prevent the skeleton of the foot from collapsing, there is an insole having a three-dimensional convex shape that supports the three arches of the sole (an inner vertical arch, an outer vertical arch, and a horizontal arch).

  However, when using these insoles in a shoe, naturally the inside of the shoe becomes cramped by the amount of the insole, which may adversely affect the foot. In particular, because the toes are all covered with upper, the pressure on the toes is inevitable.

  In addition, there are local insoles that target only specific parts, such as arches and heel parts, but not the entire sole, but it is not possible to attach such insoles to appropriate positions in shoes. It is extremely difficult, and the insole may move in the shoes by walking or the like. In such a case, it will adversely affect the foot.

  Further, various materials are conventionally used as the material for the insole. Some are too soft to absorb the impact on the foot, while others are too hard to transmit the foot impact directly to the foot.

  In order to solve these problems, the applicant of the present application has an outer shape corresponding to the inner contour of the shoe, and a layer that contacts the foot placed in the shoe and a local layer that covers only a specific part. An insole having a combined layer structure has also been proposed (Patent Document 1). The insole has an outer shape corresponding to the shoe inner contour, a surface layer in contact with the foot placed in the shoe, and an intermediate layer corresponding to the contour of the foot from the first to the fifth metatarsal head to the rib , It consists of a three-layer structure with a partial bottom layer from the arch to the buttocks. That is, since the toe portion is composed only of the surface layer, the pressure on the toes can be reduced.

  However, in the insole, the first metatarsal head and the fifth metatarsal head among the three points of the radius, the first metatarsal head, and the fifth metatarsal head that have the largest load due to body weight are applied. Since the corresponding part is located near the toe side end edge part of the intermediate layer, it is included in a tapered part formed by the toe side edge part, and the thickness thereof is thin and insufficient.

Therefore, the present invention provides an insole that does not give a feeling of pressure to the foot when worn on a shoe, and ensures a sufficient thickness in the portions corresponding to the first metatarsal head and the fifth metatarsal head. suggest.
Registration No. 4002109

    In order to solve the above problems, the applicant of the present application proposes an insole or insole structure for a shoe to be used in a shoe.

    As a first invention, from the middle of the first proximal phalanx to the line connecting the bone bottom of each proximal phalanx from the bottom of the first proximal phalanx to the bottom of the fifth proximal phalanx of the foot in the shoe A shoe insole having a cushioning material for use in such a manner that the front edge is located in a region corresponding to a region sandwiched by a line connecting the middle of each of the fifth phalanges to the middle of the fifth phalanx is proposed.

  As a second invention, the vicinity of the front edge is tapered, and the taper start region where the thickness of the cushioning material starts to decrease is at least from the first metatarsal head to the fifth metatarsal head of the foot placed in the shoe, The insole for a shoe according to the first invention, which is a region corresponding to the toe side from a region over each metatarsal head, is proposed.

  As a third aspect of the invention, a lower surface layer having an outer shape corresponding to the contour of the inside of the shoe, and a bone of each of the basic phalanges from the bone bottom of the first basic phalanx to the bone bottom of the fifth basic phalanx in the shoe. Position the front edge in the area of the lower layer corresponding to the area between the line connecting the bone bottom and the line connecting the middle of each basic phalanx from the middle of the first basic phalanx to the middle of the fifth basic phalanx Then, we propose a shoe insole consisting of a cushioning material superimposed on the bottom layer.

  As a fourth invention, the vicinity of the front edge of the cushioning material is tapered, and the taper start region where the thickness of the cushioning material starts to decrease is at least from the first metatarsal head to the fifth metatarsal foot of the foot placed in the shoe. The insole of the shoe according to the third aspect, which is a region corresponding to the toe side from the region across each metatarsal head to the bone head, is proposed.

  As a fifth invention, the insole described in any one of the first invention to the fourth invention, and the upper layer of the insole, the portion in contact with the foot placed in the shoe is natural leather, artificial leather, synthetic leather or A shoe insole structure comprising a surface layer, which is a layer made of a cloth material and a non-woven fabric, is proposed.

  The present invention provides sufficient thickness to the portions corresponding to the first metatarsal head and the fifth metatarsal head, which do not feel a feeling of pressure on the foot when worn on shoes and have the largest load due to weight. By holding it, it is possible to improve the load on the foot and the impact absorption.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this invention should not be limited to these embodiments at all, and can be implemented in various modes without departing from the gist thereof.

<< Embodiment 1 >>
<Embodiment 1: Overview>

  In the first embodiment, a line connecting the base of each base phalanx from the base of the first base phalanx to the base of the fifth base phalanx of the foot in the shoe, and the middle of the first base phalanx A shoe insole having a cushioning material for use so as to position the front edge in a region corresponding to a region sandwiched between lines connecting the middles of the five basic phalanges to the middle will be described.

“Insole” means a material to be laid in the footwear, which can be attached as one part of the footwear in the production process of the footwear or is attached later as an additional part to the footwear of the finished product. It includes not only those that can be removed but also one part of the footwear that will be the finished product, which is assembled in the footwear manufacturing process and cannot be removed. That is, the insole of the present invention may be sold separately from the footwear and attached to the footwear by the purchaser, or may be sold while attached to the footwear, or may be sold together with the footwear.
<Embodiment 1: Configuration>

    FIG. 1 shows an example of a plan view of an insole for shoes according to the present embodiment. For example, a shoe insole such as (a) or (b).

  The insole of the shoe according to the present embodiment has a cushioning material (0101). This cushioning material includes a line connecting the base of each basic phalanx from the base of the first basic phalanx to the base of the fifth basic phalanx of the foot in the shoe, and the middle from the middle of the first basic phalanx. The front end edge (0102) is located in a region corresponding to a region sandwiched between lines connecting the middles of the five basic phalanges to the middle of the five basic phalanges.

  The “buffer material” is not particularly limited as long as it has a buffering effect against an impact on the foot from the ground, such as a sponge material, a gel material, and a rubber material. For example, a polyurethane gel may be used as the gel material as in Example 1 described later. In this case, since a transparent insole can be used, even in the case of shoes such as sandals and mules where the insole can be easily seen during walking, the fashionability of the shoes is not impaired. Furthermore, since this material has adhesiveness, it is possible to prevent the insole from slipping inside the shoe when walking into the shoe. In addition, even when wearing high-heeled sandals or mules, it is possible to prevent the foot from slipping to the toe side inside the shoe. This is because the frictional force with the foot, socks and stocking material can be increased depending on the material.

    Alternatively, urethane sponge may be used as the sponge material. In such a case, a feel equivalent to that of a carpet is realized.

    The “front edge” is an edge on the toe side in the insole longitudinal direction. That is, the cushioning material does not have a toe portion. Therefore, when the insole of this embodiment is attached to a shoe, the space of the toe inside the shoe becomes narrow due to the thickness of the insole itself, and when the shoe is worn, the toe of the foot is prevented from being compressed. Can do.

  Here, each line from the bottom of the first basic phalanx to the bottom of the fifth basic phalanx and the middle of the first basic phalanx to the middle of the fifth basic phalanx A region sandwiched between lines connecting the middle of the proximal phalanx will be described with reference to FIGS. FIG. 2 shows a skeleton when the right foot is viewed from the sole, and FIG. 3 shows an inner side view of the right foot when standing. A line connecting the base of each basic phalanx from the base of the first basic phalanx to the base of the fifth basic phalanx and each basic phalanx from the middle of the first basic phalanx to the middle of the fifth basic phalanx The area sandwiched between the lines connecting the middle of the two is the area indicated by 0201 in FIG. 2, and is the first basic phalanx (0202), the second basic phalanx (0203), and the third basic phalanx (0204). In the fourth basic phalanx (0205) and the fifth basic phalanx (0206), this is a region sandwiched between a line connecting the bone bottom of each basic phalanx and a line connecting almost the middle of each basic phalanx. This area corresponds to the base of the toes and the surrounding area. The figure which looked at this from the inner side surface is FIG. In FIG. 2, a line connecting the base of each basic phalanx from the base of the first basic phalanx to the base of the fifth basic phalanx, and the middle of the first basic phalanx to the middle of the fifth basic phalanx. A region (0201) sandwiched between lines connecting the middle of the proximal phalanx is a concave portion (0301) and its peripheral region in FIG.

  Therefore, if the foot skeleton has a healthy shape, the line connecting the base of each basic phalanx from the bottom of the first basic phalanx to the bottom of the fifth basic phalanx and the middle of the first basic phalanx The region sandwiched between the lines connecting the middles of the respective basic phalanges up to the middle of the fifth basic phalanx does not make strong contact with the ground when standing. This is almost the same when walking. Therefore, when the front end edge of the cushioning material is provided in the portion, the boundary of the cushioning material is not strongly felt on the sole and the foot sole does not feel uncomfortable.

  In addition, the cushioning material includes a line connecting the bone bottom of each proximal phalanx from the bone bottom of the first proximal phalanx to the bone bottom of the fifth proximal phalanx of the foot placed in the shoe as described above, The position of the edge excluding the front edge, as long as it is located in the area between the middle of the first basic phalanx and the middle of the fifth basic phalanx and the line connecting the middle of each basic phalanx It does not specifically limit about. For example, all the edges except the front edge may have an outer shape corresponding to the shoe inner bottom contour. The outer shape corresponding to the shoe bottom part contour is a shape corresponding to the surface shape in contact with the sole inside the shoe. Thereby, it can mount | wear easily at the appropriate position inside shoes only by putting the insole of this embodiment on the shoe inner bottom part. Alternatively, the edge on the heel side in the longitudinal direction of the insole may be located in the end area on the heel side of the arch area.

The buffer material preferably has a thickness of 1 mm to 4 mm. The thickness in this case is the thickness of the part corresponding to the area | region which crosses each metatarsal head from the 1st metatarsal head of the foot | leg put into shoes to the 5th metatarsal head. The purpose is to soften the impact on the feet, relieve muscle fatigue, and suppress symptoms such as octopus, fish eyes, and keratin. This is because a thickness greater than this causes the shoes to be tight and causes a sense of incongruity and discomfort due to an increase in the thickness difference from the toe portion having no insole. More preferably, it is 2 mm.
<Embodiment 1: Effect>

According to the present embodiment, the toe portion of the foot is not tight even when worn on a shoe, and the impact on the foot is eased even when walking for a long time by softening the impact from the ground.
<< Embodiment 2 >>
<Embodiment 2: Overview>

  The present embodiment is based on the first embodiment, and further, the vicinity of the front edge of the cushioning material is tapered, and the taper start region where the thickness of the cushioning material starts to become thin is at least the first of the foot placed in the shoe. The insole of the shoe, which is a region corresponding to the toe side from the region across each metatarsal head from the metatarsal head to the fifth metatarsal head, will be described.

“Insole”, “buffer material”, and “front edge” are the same as those described in the first embodiment, and a description thereof will be omitted.
<Embodiment 2: Configuration>

FIG. 4A shows an example of a conceptual diagram of this embodiment. (A) is the longitudinal cross-sectional view of the insole of this embodiment, (b) is a top view of this embodiment, (c) is a cross-sectional view of the insole of this embodiment. Further, (d) is an enlarged view in which the vicinity of the front end edge of the longitudinal sectional view is enlarged. The vicinity of the front edge (0401) of the cushioning material is tapered (0402). In addition, the said taper start area | region is located in a toe side from the area | region which crosses each metatarsal head from the 1st metatarsal head of a foot to the 5th metatarsal head.
As shown in FIG. 4B, the taper shape does not necessarily indicate that the gradually thinning shape is necessarily linearly thin (a), but a curved shape ((A), (C)), a step shape (D). ) Also includes shapes that become progressively thinner. The examples shown in this figure are all included in a tapered shape in the present invention. In addition, the tapered shape referred to in the present invention includes a reverse tapered shape (a shape in which the upper side is projected in an eave shape as in (v) to (v)).

  The “taper start region” is a region where the taper shape starts, that is, a region where the thickness of the buffer material starts to decrease. Since the thickness of the cushioning material gradually decreases from the taper start region to the toes, the cushioning effect becomes insufficient. The taper start region and the region extending from the first metatarsal head to the fifth metatarsal head will be described with reference to FIG. 5 showing the medial side of the right foot.

  FIG. 5 is a conceptual diagram showing the relative positional relationship between the foot (0501), the foot bone (0502), and the cushioning material (0503) of the present embodiment. Here, the cushioning material (0503) is tapered on the toe side, and the front end edge (0504) is approximately halfway between the bone bottom (0505a) of the proximal phalanx (0505) of each finger and the proximal phalanx of each finger ( 0505b) at a position corresponding to the region (0505c) sandwiched between them and corresponding to the vicinity of the base of the toes (0506). The taper start area (0507) is located on the toe side of the area (0509) corresponding to the metatarsal head (0508) of each finger, that is, on the toe side of the foot treading part (0510). That is, the taper start region (0507) is located at a position corresponding to between the middle of the proximal phalanx (0505) of each finger and the metatarsal head (0508) of each finger.

  The taper start region corresponds to the toe side from the region across each metatarsal head at least from the first metatarsal head to the fifth metatarsal head of the foot placed in the shoe. In FIG. ) Is located on the toe side from the first metatarsal head to the fifth metatarsal head, the region across each metatarsal head (0509), and the tapered start region (0507) is located from the first metatarsal head to the fifth metatarsal head. Until now, it means that it does not overlap with the area (0509) across each metatarsal head. As a result, the cushioning material in the region (0509) across each metatarsal head from the first metatarsal head to the fifth metatarsal head maintains a sufficient thickness, and the buffering effect is fully exhibited.

  In FIG. 2, the taper start region is located between 0201 since the region from the first metatarsal head to the fifth metatarsal head is on the toe side of the region across each metatarsal head (0207).

  Moreover, it is preferable that it is substantially uniform thickness from the front end edge except the taper area | region of a shock absorbing material to the arch area | region. The term “from the front edge excluding the taper region to the arch region” means from the taper start region to the toe side start region of the arch region. This is because this portion is the portion where the maximum load is applied at the time of standing, walking, and running, and if the portion has a thickness deviation, the foot may be adversely affected.

Further, the structure on the heel side from the first metatarsal head to the fifth metatarsal head of the cushioning material is not particularly limited, but the arch region is configured to be thicker than the other cushioning material regions. It is preferable. This is because the thickness of the arch supports three arches (inner longitudinal arch, outer longitudinal arch, and lateral arch) on the sole, enabling prevention and alleviation of symptoms caused by arch distortion such as hallux valgus. .
<Embodiment 2: Effect>

According to the present embodiment, the buffering action of the cushioning material is surely applied to the region across each metatarsal head from the first metatarsal head to which the maximum load is applied during standing, walking, and running, from the first metatarsal head. Because it works, the impact from the ground is absorbed.
<< Embodiment 3 >>
<Embodiment 3: Overview>

    The insole of the shoe according to the present embodiment includes a lower surface layer having an outer shape corresponding to a shoe inner bottom contour, and a bone bottom of a first proximal phalanx to a bone bottom of a fifth proximal phalanx. In the area of the lower layer corresponding to the area sandwiched between the line connecting the bone base of the proximal phalanx and the line connecting the middle of each basic phalanx from the middle of the first basic phalanx to the middle of the fifth basic phalanx It is characterized by comprising a cushioning material positioned on the front edge and overlapped with the lower surface layer.

“Insole”, “buffer material”, “front edge”, and “taper start region” are the same as those described in the first or second embodiment, and thus the description thereof is omitted.
<Embodiment 3: Configuration>

  FIG. 6 shows an example of a bottom view of the lower surface layer (a) and the cushioning material (b) of the present embodiment.

  The “lower surface layer” is a layer located on the lower surface of the cushioning material, that is, the shoe inner bottom side, and has an outer shape corresponding to the shoe inner bottom contour. The outer shape corresponding to the shoe bottom part contour is a shape corresponding to the surface shape in contact with the sole inside the shoe. As a result, it is possible to easily attach the insole of the present embodiment to an appropriate position inside the shoe by simply overlaying the insole on the bottom of the shoe, and prevent the position of the insole from moving inside the shoe during walking or the like. Can do.

  The material of the lower layer is not particularly limited. For example, it may be composed of a material having a buffering effect, may be composed of natural leather, artificial leather, synthetic leather, cloth material, or non-woven fabric, or may be composed of resin or pulp board. As described above, when the surface layer described later is not provided, a part of the lower surface layer is in contact with the foot on the toe side of the foot, and in this case, a breathable material is preferable to prevent stuffiness. Also, especially when the cushioning material is made of a transparent material, the bottom layer will be noticeable when the shoe is removed, so that the material, pattern, and color (transparent, (Including translucent and metallic colors).

  Further, the thickness of the lower layer is not particularly limited. For example, as a thing to be worn on a shoe having no room in the toe portion, it is preferable to suppress the thickness, and preferably 1 mm or less.

  The cushioning material (b) is formed between a line connecting the base of each base phalanx from the base of the first base phalanx to the base of the fifth base phalanx in the foot placed in the shoe, and between the first base phalanx. To the middle of the fifth basic phalanx, the front edge (0602) is located in the region of the lower layer corresponding to the region sandwiched between the lines connecting the middle of each basic phalanx and overlapped with the lower layer. Since the cushioning material (b) has no toe portion (0601), when the surface layer described later is not provided, a part of the lower surface layer comes into contact with the foot on the toe side of the foot placed in the shoe.

  The buffer material preferably has a thickness of 1 mm to 4 mm. The thickness in this case is the thickness of the part corresponding to the area | region which crosses each metatarsal head from the 1st metatarsal head of the foot | leg put into shoes to the 5th metatarsal head. The purpose is to soften the impact on the feet, relieve muscle fatigue, and suppress symptoms such as octopus, fish eyes, and keratin. This is because a thickness greater than this may cause a sense of discomfort and discomfort due to the tightness of the shoe and an increase in the thickness difference from the toe portion having no surface layer. More preferably, it is 2 mm.

Furthermore, it is good also as an insole structure which consists of insoles in Embodiment 1, 2 or this embodiment, and also a surface layer. A surface layer is a layer used as the upper layer of an insole. Further, the portion of the surface layer that contacts the foot placed in the shoe is made of natural leather, artificial leather, synthetic leather, cloth material, or non-woven fabric. A breathable material is preferred and can prevent stuffiness. Alternatively, since it is noticeable when the shoe is taken off, it is preferable to use a material, pattern, and color (including transparent, translucent, metallic color, etc.) that do not impair the fashionability of the shoe.
<Embodiment 3: Effect>

  According to the insole of the present embodiment, the toe portion of the foot is not tight even when worn on the shoe, and the impact on the foot can be eased even when walking for a long time by softening the impact from the ground. .

  As Example 1, the experimental result about an example of the insole which concerns on this invention is shown. The insole of this example is made of polyurethane gel and has the same configuration as the insole of the second embodiment.

  FIG. 7A and FIG. 7B show the results of measuring the foot pressure distribution of a woman weighing 45 kg using a foot pressure distribution measuring device (F-scan; manufactured by Nitta Corporation). FIG. 7A is a foot pressure distribution diagram when the insole of the shoe of Example 1 is not used. (A) shows the left foot and (b) shows the right foot. FIG. 7B is a foot pressure distribution diagram when the insole of the shoe of Example 1 is used. (C) shows the left foot and (d) shows the right foot. (The items shown in color in FIGS. 7A and 7B are submitted in the property submission form of the present application.)

  When the insole of the shoe is not used, the foot pressure distribution is measured when walking on the P tile corridor in the building with the shoe on (about 5 steps). In addition, when using a shoe insole, measure the foot pressure distribution when walking (about 5 steps) with the shoe insole of this example placed on the P tile corridor in the building. Yes. Moreover, in foot pressure distribution measurement, a sensor sheet having a thickness of 0.15 mm for foot pressure measurement is overlaid directly below the foot so as to be in direct contact with the back surface of the foot.

As the maximum foot pressure value, the portion surrounded by the black square in the figure was measured. As a result, the maximum foot pressure value is (kg) of 3.4 kg / cm ² for (a), 3.5 kg / cm ² for (b), 2.6 kg / cm ² for (c), (d ) Was 2.2 kg / cm ² . That is, when the insole according to Embodiment 2 was used, the maximum foot pressure value was lower on the left and right than when not used.

  FIG. 8 is a 3D display of the foot pressure measurement results as in FIGS. 7A and 7B. As shown in this figure, the left foot (c) and right foot (d) when using a shoe insole are more than the left foot (a) and right foot (b) when not using a shoe insole, The peak is low and the contact area is wide. (The figure shown in color in FIG. 8 is submitted in the property submission form of the present application.) Also, FIGS. 9A and 9B show the contact when the foot pressure is measured as in FIGS. 7A and 7B. The area is shown. (A) Left foot without shoe insole, (b) Right foot without shoe insole, (c) Left foot with shoe insole, ( d) is a view of the right foot when using a shoe insole.

The contact area value is measured when the foot pressure value changes when walking (about 5 steps), and when the foot pressure value peaks at each step, a pressure of 0.1 kg / cm ² or more is measured. This is calculated by summing up the areas of the portions that have been added and then averaging the areas. Specifically, in FIG. 9A and FIG. 9B, it is the area of the part painted in black. This area indicates the area where the sole and the insole of the shoe are in contact when the maximum foot pressure is applied. As a result, (a) was 120.26 cm ² , (b) was 128.77 cm ² , (c) was 127.32 cm ² , and (d) was 130.06 cm ² . That is, when the insole according to the second embodiment was used, the contact area value was larger on both the left and right sides than when not used.

  As described above, when the insole of the shoe of Embodiment 2 is used, the pressure is distributed over a wider area of the sole and the maximum foot pressure value is lowered. It can prevent symptoms such as partial octopus and fish eyes, keratin, and pain.
