Description

  The present invention relates to insoles and footwear. More specifically, the present invention relates to an insole and footwear for correcting an arch structure of an arch to an appropriate shape.

  Conventionally, insole of footwear has various functions, such as a function that the feet are hard to be tired even after prolonged standing work, or a function such as stimulating a pot on the sole to improve blood circulation. Is known (see Patent Documents 1 and 2). For example, Patent Literature 1 discloses an insole that fits the shape of a sole and reduces fatigue due to long standing work or the like. In addition, Patent Literature 2 discloses an insole that can press a urn (acupoint) on the sole of a foot with the weight of the user during walking.

  Patent Literature 1 describes an insole having a main body made of an elastomer and having an elastic modulus of the main body satisfying a predetermined range.

  Patent Literature 2 describes an insole in which a flat fastener is attached to the entire surface of the insole, and large and small protrusions are movably and exchangeably engaged with each other at a plurality of positions at the pot positions of the flat fastener. ing.

  In this way, the development of insoles to protect the soles of the feet from various viewpoints and remove the discomfort of the user such as fatigue and pain, and insoles to stimulate the soles of the feet to promote health. Has been made.

  Here, the foot has an arch structure, and the arch structure of the foot acts like a spring, so that the impact applied to the ankle, the knee, the hip joint, and the waist can be reduced. Therefore, if the arch structure of the foot does not function sufficiently, walking may be hindered, or the function of supporting and maintaining balance may be impaired. Further, excessive force is applied to an ankle, a knee, a hip joint, a waist, and the like, resulting in accumulation of fatigue.

  The arch structure of the foot has three arches, an inner longitudinal arch, an outer longitudinal arch, and a lateral arch. The condition that the arch structure of the foot does not function sufficiently is that these arches are not sufficiently drawn. Is depressed. Such a state includes a flat foot, an open leg, and the like. Note that a flat foot corresponds to a foot in a state in which the inner vertical arch of the three arches in particular has fallen, and the function of alleviating impact is weakened. In addition, the open leg corresponds to a leg in a state where the horizontal arch is depressed.

  It is known that the state in which the arch is not sufficiently drawn and the arch is depressed gradually occurs due to aging, lack of exercise, and the like. In other cases, the arch may not be fully drawn in its natural state.

  In this way, the arch structure of the foot may not function sufficiently due to aging, etc., and walking disorders etc. occur due to the insufficient function of the arch structure of the foot, regardless of age or gender. There is. In other words, because it is a problem that can occur to everyone, the arch that is not sufficiently drawn and falls down to make it impossible to draw the arch structure is converted into a shape suitable for each ideal sole (an arch with a sufficiently drawn arch) It is important to restore to the arch shape having a structure). Furthermore, the arch structure of each foot is improved to have an appropriate shape so that the arch has a sufficient arch structure (ie, the ideal arch structure differs for each user, It is important to improve the shape so that the shape of the arch matches. Such "recovering" or "improving" is referred to herein as "correcting".

  The insoles described in Patent Documents 1 and 2 cannot sufficiently cope with such a problem. Specifically, the insole of Patent Document 1 adopts a predetermined material, so that the insole is lightly hit by the arch of the user and the fit of the insole to the sole is improved, thereby reducing fatigue and the like. Is what you do. However, with the insole of Patent Literature 1, it is difficult to restore the arch structure of the foot even if the insole is fitted to the actual shape of the sole with the arch depressed. Furthermore, the arch structure of the foot cannot be improved to a shape suitable for each foot. Therefore, the insole of Patent Literature 1 does not have a function of restoring the arch structure of the foot and a function of improving the arch structure.

  The acupressure insole described in Patent Literature 2 is capable of giving a pressing stimulus equivalent to stepping on green bamboo by pressing a predetermined portion required for acupressure (that is, a urn on the sole) by the acupressure protrusion. it can. However, in the insole for acupressure described in Patent Literature 2, the pressure points are simply pressed, and it is difficult to restore the arch structure of the foot, and the arch structure cannot be improved at all. Therefore, the acupressure insole described in Patent Literature 2 does not have a function of restoring the arch structure of the foot and a function of improving the arch structure.

  As in Patent Literatures 1 and 2, there are known insoles having various functions, but as described above, insoles intended to restore the arch structure of the foot, and further improved arch structure Insoles intended to do so are not known. Therefore, development of an insole and footwear capable of restoring an arch where a sufficient arch structure cannot be drawn to an ideal shape and further improving or correcting the arch has been desired.

  SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the related art, and has as its object to accurately grasp the actual position and shape (planar shape) of the foot with the arch lowered. Then, based on the actual condition of the foot, by providing a positioning portion that pushes the arch slightly higher than this, the arch structure of the arch is gradually restored to an appropriate shape, and further improved, that is, An object of the present invention is to provide an insole and footwear for correction.

  Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments, and based on ordinary knowledge of those skilled in the art, without departing from the spirit of the present invention. It is to be understood that modifications, improvements, etc., of the embodiments described above are also included in the scope of the present invention.

[1] Insole:
One embodiment of the insole of the present invention is the insole 100 shown in FIGS. The insole 100 is an insole to be inserted as an insole into footwear, and includes a positioning portion 10 that can position a position of an arch on a back surface of a foot, and the positioning portion 10 has a corrected arch height that is higher than an actual arch height. In addition, an arch height adjusting mechanism 11 that can adjust the arch is provided.

  In such an insole 100, since the positioning portion 10 is disposed in an appropriate position and shape (planar shape), the arch is pushed up from below by the positioning portion 10, and the arch structure of the arch is restored and further improved. (Ie, the arch structure of the arch can be corrected to an appropriate shape). In other words, the arch structure of the arch is gradually restored to an appropriate shape by the positioning portion 10 and further improved (corrected). This is achieved by arranging the positioning portion 10 at an appropriate position. It is important to make the shape (planar shape) appropriate. For this purpose, the actual position of the foot (the position in the front and rear and left and right directions on the sole) and the shape (planar shape) of the foot with the arch depressed are specifically and accurately grasped, and based on the information of the actual arch of the foot. In addition, the positioning portion 10 is formed, and the height of the positioning portion 10 is pushed up slightly to a height slightly higher than the actual arch height (to such an extent that strong pain is not felt). The “appropriate shape” of the arch structure of the arch differs depending on the state of the sole of each user, but refers to a shape close to an individual ideal arch based on the actual state of the arch.

  Since the user can push up the arch from below by the positioning portion 10 while using the insole 100, the arch structure of the arch is gradually corrected to an appropriate shape.

  Here, the “correction arch height” is a position (height) higher than the actual arch height, and is a height at which strong pain is not felt. The reason for adjusting the “corrected arch height” is that, for example, in the case of a flat foot, it is considered that there is a great difference from the ideal arch structure. If the height of the positioning part 10 is set so as to have a structure, the pain felt by the user becomes too strong.

  The insole of the present invention only needs to have a size that can cover at least the arch region, and can cover the entire sole of the foot (specifically, from the toe portion of the foot). That cover the heel of the foot).

  In this specification, “footwear” widely includes shoes, sandals, and the like.

[1-1] Positioning unit:
The positioning section 10 is for correcting the arch of the arch structure of the arch, accurately reflects the shape (planar shape) of the arch of the user, and furthermore, the position of the arch (position in the front-rear, left-right direction on the sole). ) Are arranged with high accuracy.

  The position and shape (planar shape) of the positioning portion 10 can be determined by the arch determining means 15. The arch determining means 15 is for transferring and visualizing at least a portion (area) of the arch in the planar shape of the back surface of the foot, and is arranged on the outermost surface of the insole body 20 (insole 100) and provided for the user. It is in direct contact with the sole of the foot. By the arch determining means 15, the user can visualize the unevenness state of the sole of his / her foot (that is, particularly the position and shape of the arch) in a planar manner (that is, the position of the arch on the sole of the user). And the shape can be grasped accurately). As a result, the positioning portion 10 can be formed favorably. As described above, according to the arch determining means 15, it is possible to easily take the user's footprint in a state where at least the position and the planar shape of the arch are known, and to form the positioning portion 10 well based on this footprint. can do.

  The arch determining means 15 may have any size as long as it can cover at least the region of the arch (a portion corresponding to the arch), and can entirely cover the soles of the foot (specifically, May cover from the toe portion of the foot to the heel of the foot). FIG. 1 shows an arch determining means 15 that is large enough to cover the arch region.

  As the arch determining means 15, for example, a sheet body having a surface layer having a plurality of raised hairs (that is, a surface layer having raised hairs on the surface), a discoloration sheet, and the shape of a portion to which a force is applied by an external force are changed. Resins (such as resin sheets) can be used.

  As the sheet body (brushed sheet body) provided with a surface layer having a plurality of naps, specifically, a sheet body obtained by subjecting the surface layer to flocking (flocking) and planting short fibers can be cited. . This raised sheet body has a plurality of fine raised surfaces formed on a surface layer, and the raised surface is collapsed by external pressure. When such a raised sheet body is used, when the user puts his or her foot on the insole body (that is, when the user steps on the foot), the raised portion of the stepped portion falls down, and the raised portion of the non-stepped portion is convex. Remains in shape. Since the arch is not touched by the raised sheet body, it can be seen that the region where the raised surface is present while maintaining the convex shape corresponds to the arch. In this manner, the position of the arch and the planar shape (the contour of the arch) on the sole of the foot can be accurately recognized.

  Examples of the discoloration sheet include a sheet that is discolored for a predetermined time after the sole of the foot is placed. For example, a sheet (temperature-sensitive sheet) that changes color due to temperature (body temperature of the sole), a sheet (moisture-sensitive sheet) that changes color due to adhesion of moisture (such as sweat on the sole), and a sheet that changes color when subjected to pressure (pressure-sensitive sheet) ).

  The temperature-sensitive sheet is not particularly limited, and specific examples thereof include a sheet provided with a color-change film made of a paint (ink) that changes color at a specific temperature on its surface.

  The moisture-sensitive sheet is not particularly limited, and specific examples thereof include water-sensitive paper (water-sensitive test paper).

  The “resin whose shape changes at the portion where the force is applied by the external force” is not particularly limited, but specific examples include a resin sheet having a resin layer made of a resin that is plastically deformed by an external force. The resin may have a property that does not return to the original shape after the shape is changed, or may have a property that returns to the original shape after the shape is changed. In the case of the property of returning to the original shape, the time until returning to the original shape is not particularly limited, and may be, for example, a time (for example, 1 minute or more) sufficient to produce the positioning unit 10.

[1-1a] Arch height adjustment mechanism:
The arch height adjustment mechanism 11 adjusts the height of the positioning unit 10. The arch height adjusting mechanism 11 can adjust the extent to which the arch is pushed up from below, so that, for example, the user does not feel strong pain while pushing up the arch in use. it can. As described above, by setting the positioning portion 10 to be slightly higher than the actual arch height by the arch height adjusting mechanism 11, the arch structure of the arch can be corrected to an appropriate shape.

  The arch height adjusting mechanism 11 can have an arch support portion 21 that is detachable along the thickness direction of the insole 100. As the arch support 21, for example, a pin (rod-like body) 23 as shown in FIG. 7, a material made of a material which is deformed by temperature, a material made of a spring material, and the like can be given. In the case of the pin 23, the opening diameter of the hole 24 can be smaller than the outer diameter of the pin 23. In this case, after the pin 23 is inserted into the hole 24, The position can be prevented from being shifted. When the pin 23 is used, the pin 23 may be inserted into the insole body 20 where the hole 24 is not formed, instead of being inserted into the hole 24.

  The shape of the pin 23 is not particularly limited, and may be, for example, a column, a polygonal column, or the like.

  The material of the pin 23 is not particularly limited, and examples thereof include a flexible member (for example, a synthetic resin such as urethane, silicone, and rubber), and a rigid member (for example, metal and wood). it can.

  The pins 23 may have only the same length (height), or may have various lengths (heights). Providing various lengths makes it easier to adjust the height of the arch.

  As shown in FIGS. 4 and 10, the insole body 20 has a plurality of holes 24 having openings 26 formed in the surface thereof. Can be. The number and size (opening diameter) of the holes 24 can be determined as appropriate. In addition, the hole portion 24 may penetrate the insole body 20 or may not penetrate.

  Examples of “a material made of a material that is thermally deformed” include, for example, a material having a columnar shape similar to that of a pin, and a material whose axial length is extended by temperature (for example, body temperature). When such a structure is employed, when the user uses the insole, the arch is extended to a predetermined length by the body temperature of the user, so that an appropriate pressure can be applied to the sole of the user. In addition, the shape of “the material made of a material that is deformed by temperature” is not limited to the columnar shape similar to the pin, and can be appropriately determined.

  As the “composed of a spring material”, for example, a material having a columnar shape similar to a pin and having a spring force acting so as to spread in the axial direction can be used. When such a structure is employed, when the user uses the insole, an appropriate pressure can be applied to the sole of the user by the force of the spring of the arch and the support portion. In addition, the shape of "the one made of a spring material" is not limited to the columnar shape similar to the pin, and can be appropriately determined.

[1-2] Cover member:
The insole according to the present invention can further include a sheet-like cover member 30 that covers the positioning unit 10 like the insole 101 shown in FIG. By further providing the cover member 30, it is possible to prevent the positioning part 10 from directly touching the sole of the user's foot, so that the positioning part 10 directly touches the sole of the user's foot. It is possible to prevent the user from feeling pain.

  A plurality of holes may be formed in the cover member 30. By forming this hole, the hole can be fitted with the pin 23 arranged on the insole body 20, and the cover member 30 can be fixed to the insole body 20.

  Since the cover member 30 is in direct contact with the sole of the user, the cover member 30 may be made of a material having flexibility.

  The cover member 30 only needs to have a size capable of covering at least the positioning portion 10, and can cover the entire sole of the foot as shown in FIG. Those that cover from the toes to the heels of the feet) are preferred.

[1-3]: Convex part arrangement means:
As in the insole 102 shown in FIG. 8, the insole of the present invention may further include a convex portion arranging means 40 on the surface of the insole body 20 in addition to the positioning portion 10. The convex portion arranging means 40 is arranged by the user at a desired position as needed, and can be arranged, for example, near the base of the finger or near the heel. Here, when the convex portion arranging means 40 is arranged at the base of the finger, the toes are in a state of grasping the insole, so that the insole can be prevented from shifting during use. In addition, when the convex portion arranging means 40 is arranged near the heel, it is possible to prevent the user's foot from moving back and forth during use and to prevent the insole from being displaced satisfactorily. it can.

  As the convex portion arranging means 40, the same one as the above-mentioned arch support portion 21 can be appropriately adopted. Specifically, the pin 23 described above can be used.

  FIGS. 8 and 9 show the insole 102 in which the convex portion arranging means 40 is arranged near the base of the finger and near the heel, respectively. The position of the projection arrangement means 40 can be appropriately selected by the user. 8 does not show the cover member, and FIG. 9 is a side view of the insole 102 shown in FIG. 8 as viewed from the side.

[1-4]: Insole body:
FIG. 10 shows another embodiment of the insole body provided in the insole of the present invention. In the insole body 20 shown in FIG. 10, the hole 24 is formed on the entire surface of the bottom surface 42. That is, in the insole body 20 shown in FIG. 10, the hole 24 is formed in the region other than the region of the arch determination means 15, and by adopting such a configuration, the protrusion arrangement means 40 can be arranged more freely. It is possible to produce an insole that is more suitable for the sole of the user. Note that the insole body 20 refers to an insole in a state where the positioning unit 10 is not arranged.

[2] How to use the insole:
Before mounting the insole on the footwear, first, the insole body 20 as shown in FIG. 4 is prepared, and the sole of the user 50 is fitted on the insole body 20 as shown in FIG. At this time, the arch determining means 15 is arranged on at least a part of the surface of the insole body 20, and the position and shape of the arch can be copied (transferred and visualized) (see FIG. 6). Here, the arch of the user 50 is not in contact with the arch determining means 15. In other words, an area where the arch is located on the insole body 20 (an arch area 60) can be obtained.

  Thereafter, the positioning portion 10 is formed by the arch height adjusting mechanism 11 (the pin 23 and the hole 24 in FIGS. 6 and 7) in accordance with the position and shape of the arch that has been copied (that is, the arch region 60). The arch height adjusting mechanism 11 adjusts the arch to a “corrected arch height” higher than the actual arch height of the user.

  More specifically, when the arch height adjusting mechanism 11 has an “arch support portion 21” including a pin 23 (see FIG. 1 and the like) detachable along the thickness direction of the insole 100, the pin 23 is replaced with the insole 100. It is inserted into a hole 24 having a plurality of openings 26 formed in the surface of the main body 20, and the height is adjusted. The pins 23 are arranged in accordance with the position and shape of the arch which has been copied (see FIG. 1). Here, the height of the pin 23 is higher than the actual arch height of the user (corrected arch height), and the arch is pushed up from below so as to correct the arch structure of the arch. The extent to which the arch is pushed up from below can be adjusted as appropriate, and while the arch is pushed up from below, for example, the user does not feel strong pain. In this way, the positioning portion 10 for determining the position of the arch on the back surface of the foot is formed.

  The cover member 30 can be appropriately disposed on the insole 100 where the positioning portion 10 is formed as described above (for example, see FIG. 3). Thereafter, the insole 100 can be attached to the footwear (footwear 200 or the like) and the footwear can be worn.

  In addition, as shown in FIG. 8, at a position other than the position corresponding to the arch (for example, near the heel or at the base of the finger), the protrusion arranging means 40 (for example, the above-described pin 23) can be arranged. By doing so, it is possible to prevent the insole from being shifted during use, and to properly correct the arch structure of the arch.

[3] Footwear with insole:
FIG. 11 shows a footwear 200 including the insole of the present invention. This footwear 200 is a footwear that houses the insole (such as the insole 100) of the present invention described above. As the footwear 200, conventionally known footwear can be appropriately used, and can be used instead of the insole of the conventionally known footwear. FIG. 11 is a partial cross-sectional view schematically showing one embodiment of footwear including the insole of the present invention.

[4] Footwear:
One embodiment of the footwear of the present invention is a footwear 201 shown in FIG. The footwear 201 is specifically sandals. The footwear 201 includes a positioning portion 10 that can position the position of the arch on the back surface of the foot. The positioning portion 10 has an arch height adjustment that can adjust the arch to a corrected arch height that is higher than the actual arch height. It has a mechanism 11.

  The footwear thus configured can restore the arch structure of the arch to an appropriate shape and further improve (ie, correct).

  The footwear 201 includes a bottom part 210 and a covering part 211, and the positioning part 10 is arranged on a surface of the bottom part 210. Further, the cover member 30 of the footwear 201 is arranged so as to cover the positioning unit 10. In the footwear 201, the convex portion arranging means 40 including the pin 23 is arranged near the heel and at a portion corresponding to the base of the finger. In this footwear 201, since the covering portion 211 is opened and the surface of the bottom portion 210 is exposed, it hinders the user from positioning the arch and arranging the arch support 21 (pin 23). It is not going to be.

  The footwear 201 can be used after forming the positioning part 10 as follows. First, the covering portion 211 of the footwear 201 before the support portion 21 is disposed is opened to expose the surface of the bottom portion 210. Then, the user's foot is placed on the surface of the bottom 210, and the position and shape (planar shape) of the user's arch are copied to the arch determining means 15 (transferred and visualized). Thereafter, the arch support 21 (for example, the pin 23) is arranged in accordance with the position and shape of the arch that has been copied (see FIG. 12). The height of the positioning portion 10 is a position higher than the actual height of the arch. Specifically, the height is a position slightly higher than the actual height of the arch, and is set to a height at which the user does not feel strong pain. After that, the convex portion arranging means 40 composed of the pins 23 is arranged at a predetermined position (the arch region 60 (see FIG. 6)), and after the cover member 30 is arranged, the covering portion 211 is closed. The user can use in such a state.

  The insole of the present invention can be used as an insole for footwear. The footwear of the present invention is shoes, sandals, and the like.
