Description

      The present invention relates to a shoe insole.

Conventionally, insoles for shoes, arches and arches to adhere the foot side to the sole of the foot, and a cubic bone supporting projection that supports the foot from the sole with the cubic bone as a fulcrum, 2. Description of the Related Art An insole has been known in which a skeletal balance of a foot is adjusted by a cubic bone supporting projection to allow a foot to move around a cubic bone as a fulcrum (for example, see Patent Document 1).

  Conventionally, insoles for shoes, arches and arches to adhere the foot side to the sole of the foot, and a cubic bone supporting projection that supports the foot from the sole with the cubic bone as a fulcrum, The cubic bone supporting projection adjusts the skeleton balance of the foot, and the projection supports the foot with the cubic bone as a fulcrum and allows the foot to move around the projection at the sole surface corresponding to the cubic bone. A shape that applies maximum stress and gradually reduces the stress acting on the sole of the foot, including the part corresponding to the scaphoid from the part corresponding to the cubic bone toward the side edges, and on the sole of the foot forward and backward 2. Description of the Related Art An insole that allows a shape for gradually reducing an acting stress is known (for example, see Patent Document 2).

  Conventionally, from the part corresponding to the cubic bone to the left and right side edges including the part corresponding to the scaphoid bone to gradually decrease the thickness, and from the part corresponding to the cubic bone downward and forward to the front and rear. The thickness is gradually reduced, and the thickness is gradually reduced in the front, rear, left and right radial directions, and is provided with a cubic bone supporting protrusion for supporting the cubic bone from the sole, and is arranged so as to overlap the cubic bone supporting protrusion. By supporting the calcaneal tuberosity through the long plantar ligament, in a state where the movement of the foot is allowed around the cubic bone supporting protrusion, the distortion of the heel cubic joint with respect to the lateral vertical arch of the sole is suppressed. There has been known a shoe insole provided with a calcaneal front support protrusion for supporting the calcaneal front from the sole. (For example, see Patent Document 3).

  Conventionally, as a member interposed between the boot and the inner boot of the ski boot, it has a ridge line with respect to the center line of the sole, and has a curved inclined surface that becomes lower in a curved concave shape on both left and right sides in the ski boot width direction, A method is disclosed in which a member having a reduced width of the winter member is provided in the direction of the toes or the heel of the ski to facilitate the left-right movement for ski operation. (For example, Patent Document 5)

Patent No. 5263880 (JP, B2) Patent No. 4733957 (JP, B2) Patent No. 5498631 (JP, B2) WO201743658A1 Patent specification Japanese Patent Application No. 2015-179830 patent specification

In the above-described conventional provision of the member having the curved inclining surface which becomes curved concavely on both the left and right sides in the width direction on the insole or the inclusion between the inner boot and the ski boot, the object is to facilitate the movement in the left and right direction. For this reason, no consideration has been given to the change in the motion of the sole weighted movement in the front-rear direction (hereinafter simply referred to as weighted movement). Therefore, a delay in the movement occurs during the weighted movement, and the user needs extra body advance movement and muscle strength to move the center of gravity, and the burden on the body, especially muscles and joints, is large.
The present invention has been made in view of the above circumstances, and has as its object to provide a shoe insole that supports a lower limb in a well-balanced manner and that can be smoothly weighted and moved.

In the conventional insole, although the stability of the sole can be ensured, it has been difficult to smoothly move the load in a practical operation that requires simultaneous movement of the sole load in the boot in the front-rear direction. Another object of the present invention is to balance the sole load with a cubic bone supporting projection that supports the side of the foot and supports the cubic bone without shaking the foot. However, there is a need for more balanced support of the feet. In addition, because the emphasis was placed on supporting and stabilizing the foot, the load movement of the sole required for walking and exercising was not taken into account. However, no consideration has been given to a change in the motion of the sole weighted movement (hereinafter abbreviated as weighted movement) from the stable state of the load. Therefore, a delay in the movement occurs during the weighted movement, and the user needs extra body advance movement and muscle strength to move the center of gravity, and the burden on the body, especially muscles and joints, is large.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a shoe insole that supports a lower limb in a well-balanced manner and that can smoothly move by weight.

  In order to achieve the above object, the insole of the present invention has a ridge line on the line from the distal phalanx to the calcaneus of the second finger, and gradually reduces the thickness of at least a part of the ridge line inside and outside of the foot to move the load to the left and right. In this way, the movement required in the left-right direction is assisted by reducing the load required for the movement.

  On the other hand, the insole thickness is gradually reduced from the line connecting the mother and child ball to the small ball, to the tip of the distal phalanx, and the insole thickness is gradually reduced from the tip end of the cubic bone to the calcaneus to assist in moving the load in the front-rear direction. I do.

  In addition, by gradually reducing the insole thickness of the cross part formed by the line connecting the mother and child ball to the small ball and the line connecting the second phalanx of the second finger to the center of the calcaneus, the impact force upward from the sole is absorbed, Reduce the load on the joints of the body, including the feet.

  As an example of the above-described method, a rhombus is formed by forming a cross on a line connecting a portion corresponding to the small bone of the thumb ball to a portion corresponding to the seed bone of the little finger and a line from the distal phalanx to the calcaneus of the second finger. The insole bottom thickness is reduced from the crosshair to the bottom side of the rhombus in the side and front and back directions, and the sole that supports the sole with the dent formed in the crosshair is a dent with the maximum projection height crosshair gradually reduced By providing a concave portion, the load moves toward the seed bone at the toe, and then moves forward, when the foot moves from the landing point of the sole to the next moving part, for example, when walking with the heel during normal walking. At this time, there is a method in which the load is moved to the heel side shortly after moving to the heel side and kicks the foot backward, thereby performing an action of generating a force for moving the body forward.

  In order to perform the above-mentioned plantar load movement, the insole shape of the bottom of the heel has a hemispherical shape, and the part corresponding to the seed bone of the thumb ball to the part corresponding to the tip of the metatarsal side of the baseball phalanx of the thumb. By forming a rhombic shape with respect to the center of intersection between the line connecting and the line from the seed bone of the second finger to the connecting heel side of the talus and calcaneus, the load can be easily moved in any direction of the center of intersection. Further, by providing the cross recess at the center of the intersection, the deformation of the insole suitable for the load movement is obtained, and the load stability and the load movement are facilitated.

  With the above configuration, on the line connecting the part corresponding to the seed bone of the thumb ball to the part corresponding to the tip of the metatarsal side of the baseball of the small ball, and from the distal phalanx of the second finger to the connecting heel side of the calcaneus A foot with a rhombic shape with the center of the cross on the line as the apex, the bottom thickness of the insole is reduced from the crosshair in the previous crosshair, the thickness is reduced in the side and front and rear directions, and the dent with the maximum projection height crosshair is gradually reduced in the crosshair. An independent member for attaching a member having a concave portion to the member supporting the bottom to the insole may be used as a general insole bottom surface.

  In the above configuration, the cruciform formation part is on a line connecting the part corresponding to the seed bone of the thumb ball to the part corresponding to the tip of the metatarsal side of the base phalanx of the small ball, and the distal phalanx to the calcaneus of the second finger.

  In the above configuration, the cruciform part is a connection between a part corresponding to the seed bone of the thumb ball and a part corresponding to the tip of the metatarsal side of the basal phalanx of the small ball, and the connection between the second distal phalanx and the calcaneus. On the heel side, the radial cross-forming portion may use a member independent from the insole having an area of 0.1 or more of the foot width and the foot long area with respect to the center of the cross line.

  The member independent of the insole having an area of 0.1 or more of the independent foot width and foot length area may be made of carbon material such as carbon or graphite, or resin material such as polyurethane and / or nylon or ABS.

  In the above configuration, the cruciform formation part is on a line connecting the part corresponding to the seed bone of the thumb ball to the part corresponding to the tip of the metatarsal side of the base phalanx of the small ball, and the distal phalanx to the calcaneus of the second finger. It may be formed of a member independent from the insole having an area of 0.1 or more of the foot width and / or foot tone on the line toward the connecting heel side, and a cross-shaped groove may be formed in the support reinforcing member.

  In the above configuration, on the line connecting the part corresponding to the seed bone of the thumb ball to the part corresponding to the tip of the metatarsal side of the baseball of the small ball, and from the distal phalanx of the second finger to the connecting heel side of the calcaneus The bottom of the insole is gradually reduced in the side and front and back directions from the crosshairs, and the maximum protrusion height The crosshairs are gradually reduced in the crosshairs to support the sole formed in the crosshairs It is also possible to form a structure having a concave portion in the member to be formed, a seed bone of the thumb ball, and a concave portion in the calcaneus.

  In the above configuration, the thin foot-shaped support member includes a line connecting a portion corresponding to the seed bone of the thumb ball to a portion corresponding to the tip of the metatarsal side of the baseball of the small ball, and the distal phalanx of the second finger. From the cruciform line, the thickness of the insole bottom surface is reduced in the lateral and anteroposterior directions, and the dent that gradually reduces the maximum projection height cross line It may be formed as a structure having a concave portion in a member supporting the sole formed in the crosshairs, a seed bone of a thumb ball, a seed bone, and an additional member for attaching a recess to the calcaneus.

  In the present invention, the cruciform formation portion is radially directed on a line connecting a portion corresponding to the seed bone of the thumb ball to a portion corresponding to the seed bone, and on a line extending from the distal phalanx of the second finger to the connecting heel side of the talus and the calcaneus. The cross-forming part is placed on the cross line with the bottom end facing the thumb ball and the small child ball, has an area of 0.1 or more of the foot width foot length with respect to the center of the cross line, and has a diamond-shaped or diamond-shaped center line. The heel side may be formed into a deformed rhombus shorter than the fingertip side to serve as a support reinforcing member.

  In the present invention, the cross-forming portion is a connection between a portion corresponding to the seed bone of the thumb ball and a portion corresponding to the tip of the metatarsal side of the proximal phalanx of the small ball, and a connection between the distal phalanx of the second finger and the calcaneus. The radial cross-forming part on the line from the heel side is located at the cross line with the bottom end facing the thumb ball and the small ball, and has an area of 0.1 or more of the foot width foot length with respect to the center of the cross line. Alternatively, the support reinforcement member may be a rhombus or a rhombus with a deformed rhombus whose center line on the heel side is shorter than the fingertip side.

  In the present invention, the cross-forming portion is a connection between a portion corresponding to the seed bone of the thumb ball and a portion corresponding to the tip of the metatarsal side of the proximal phalanx of the small ball, and a connection between the distal phalanx of the second finger and the calcaneus. The radial cross-forming portion on the line toward the heel side may gradually reduce the core material of the insole.

  In the present invention, the cross-forming portion is a connection between a portion corresponding to the seed bone of the thumb ball and a portion corresponding to the tip of the metatarsal side of the proximal phalanx of the small ball, and a connection between the distal phalanx of the second finger and the calcaneus. The radial cross-forming portion on the line extending to the heel side may use a material having a different elastic modulus.

  In the present invention, the cross-forming portion is a connection between a portion corresponding to the seed bone of the thumb ball and a portion corresponding to the tip of the metatarsal side of the proximal phalanx of the small ball, and a connection between the distal phalanx of the second finger and the calcaneus.

The support reinforcement member may be a deformed rhombus whose heel side of the line is shorter than the fingertip side.

  According to the present invention, the main requirement is to support the weight of the user while supporting the movement of the foot, and the diamond-shaped three-dimensional structure on the bottom of the insole plays an important role in weighted movement and rotation movement. Since the sole of the sole is reduced in thickness at the ridge line (cross shape) of the rhombus portion to form a depression, the stress generated by the movement of the load can be alleviated, so that the movement of the load is further facilitated. In addition, since the sole (sole) surface is supported by forming a recess in the insole-facing portion of the thumb ball, small ball, and calcaneus, the entire sole (sole) is stabilized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a cross section of a line connecting the tip of the second phalangeal phalange of the insole 1 to the center of the calcaneus at the bottom, and the bottom is the outer view of the right foot, the middle is the sole skeleton corresponding to the outside, and the bottom is is there. The bottom section of the insole 1 shows that the thickness of the insole 1 gradually decreases from the foot working side of the medium-speed bone toward the proximal phalanx, and the thickness of the insole 1 further gradually decreases from the proximal phalanx toward the distal phalanx. ing. In addition, the thickness of the insole 1 from the tip end of the cuboid to the center of the fibula is gradually reduced, the thickness from the center of the fibula to the center of the calcaneus is gradually reduced, and the thickness of the insole 1 from the center of the calcaneus to the posterior end of the calcaneus. Is gradually reduced.

FIG. 2 is a perspective view showing the insole according to the present embodiment from the bottom. The insole 1 has a shape following the internal contour of the shoe in plan view. By matching the outer edge shape to the inner edge shape of the shoe, the insole 1 is attached to a predetermined position in the shoe at the time of insertion. Since the shape of the foot of the user using the insole 1 varies from person to person and is not constant, the entire size of the insole 1 is selected according to the size of the foot of the user. In addition, the thickness of each part of the insole 1 can match the foot shape specific to the user by changing the thickness of the interference member and the core material. Versatility can be accommodated by preparing multiple sizes and thicknesses. By preparing the insole 1 having a plurality of thicknesses and a plurality of sizes, versatility can be provided.
As described above, the bottom surface of the insole gradually decreases toward the inside and outside of the foot, with the line connecting the tip of the second phalanx of the second finger to the center of the calcaneus as the ridge line.

  The insole 1 can conform to the unevenness of the sole surface by deforming the core material shape for obtaining rigidity according to the last. In addition, a deformed rhombus having the ridge lines 23 and 24 of the insole 1 is formed to facilitate the load movement of the sole in the weight moving direction of the insole 1. Prepare an insole without unevenness in advance and attach a separate uneven portion Fig. 12 to the surface of the flat insole detachably, or make the insole a plurality of layers, separate the uneven portion on the sole side and the sole side separately The same effect can be obtained by forming irregularities on the surface material.

FIG. 3 is a perspective view showing a sectional view of a ridge line from a thumb ball to a small ball of the insole according to the embodiment of FIG. FIG. 4 is a cross-sectional view of a ridge line from the second phalanx of the second finger to the metatarsal of the insole according to the embodiment of FIG.
The insole 1 has a shape following the internal contour of the shoe in plan view. By matching the outer edge shape to the inner edge shape of the shoe, the insole 1 is attached to a predetermined position in the shoe at the time of insertion. Since the shape of the foot of the user using the insole 1 varies from person to person and is not constant, the entire size of the insole 1 is selected according to the size of the foot of the user. In addition, the thickness of each part of the insole 1 can match the foot shape specific to the user by changing the thickness of the interference member and the core material. Versatility can be accommodated by preparing multiple sizes and thicknesses. The insole 1 can be made versatile by preparing several types of thicknesses and sizes.
The insole 1 can conform to the unevenness of the sole surface by deforming the core material shape for obtaining rigidity according to the last. In addition, a deformed diamond-shaped portion 23 (see also FIG. 5) is formed in a deformed rhombus having the ridge lines 23 and 24 of the insole 1 to facilitate the deformation of the insole 1 in the weight moving direction. Also, a flat insole having no irregularities is prepared in advance, and a separate deformed rhombus member (FIG. 12) is detachably attached to the surface of the flat insole, or the insole is formed as a plurality of layers, and the sole side and the foot are formed. The same effect can be obtained by forming irregularities on the surface material by bonding irregularities on the back side.

  FIG. 6 is a plan view showing the thinned portion 23 from the seasonal bone to the metatarsal bone on the ridge line from the thumb ball to the small ball and the midline of the calcaneus from the second phalange of the insole according to the embodiment of FIG. It is the figure shown from the bottom. This cross-shaped insole gradually decreases in thickness, whether it is formed at the bottom of the insole, at the corresponding portion of the core material, at the top of the insole, or when the material of the portion is made of a material with a higher elastic modulus than other parts. The same effect can be obtained by using a material in which is reduced.

  The insole 1 can easily move the sole load forward, backward, left and right by configuring the deformed rhombus described above. Further, as shown in FIG. 6, by gradually reducing 22 in a cross shape, a rhombus-shaped load movement easiness is provided on the bottom surface of the insole. The amount of change in the force required for movement is reduced. The same effect can be obtained by detachably attaching only the deformed rhombus portion shown in FIG. 13 to the flat insole surface as a separate member from the insole. FIG. 7 is a cross-sectional view of the cross-shaped gradually decreasing portion from the thumb ball to the child ball. Similarly, FIG. 8 is a cross-sectional view of the cross-shaped gradually decreasing portion from the second finger seasonal bone to the metatarsal bone.

FIG. 9 is a diagram schematically showing the relationship between the outer edge of the insole 1 and the skeleton of the foot. In the above-mentioned cross-shaped gradual decrease, the cutting width is appropriately adjusted with the center lines of 32 and 33 on the bottom of the insole. The mother and child ball is the first seed bone portion, and the small child ball is the tip of the fifth metatarsal toe.
In this case, the sole skeleton is taken as an example of the right sole, but it goes without saying that the sole skeleton is mirror-image right and left. The appropriate width and length of the cruciform taper is the longest heel of the metatarsal from the maternal and spheroid and from the tip of the second distal phalanx. However, even if the user is a sports expert or a healthy person, the physical strength / muscular strength, the disabled person and the injured person in the rehabilitation process should be able to appropriately adjust the ease of movement using an easy-to-cut material such as cork or resin material. The effect can be further obtained by individually adjusting.

  In the case of realizing with a modified rhombus, it is preferable to form the maximum between the distal phalanx and the seasonal bone, the heel side end of the metatarsal bone, and the bottom surface having the first to fifth trabeculae as vertices. It is preferable that the removable rhombic member shown in FIGS. 12 and 13 has the same bottom surface.

  FIG. 10 shows the portion of the mother and child ball, small child ball, and calcaneus where the core material is to be cut out together with the skeleton, as viewed from the bottom of the sole. FIG. 11 is a diagram showing a circular concave cross section of the core material of the mother and sphere, and the circular concave of the calcaneus also reduces the thickness of the core like the mother and sphere. Since the power point at the time of moving the load is stabilized by the thickness reduction, the effect of promoting the movement of the sole load can be obtained.

  FIG. 12 shows three outline views of the modified rhombus. At the side of the sports boot such as shoes or ski boots, the tip of the deformed rhombus is placed on the insole so that the upper side in FIG. 12 is in contact with the upper side. By placing the opposing apex of the bottom of the above on the line connecting the distal end of the second phalanx of the second finger and the calcaneus, it is possible to obtain the same effect as that of the deformed rhombus integrated with the insole. By providing a recess from the apex to the center of the maximum height of the diamond, the recess is deformed when the load moves in the front-rear and left-right directions similarly to the insole-integrated type, so that the stress is relieved and the load movement is further facilitated.

  The shoe insole of the present invention is intended to improve the standing posture and the walking and athletic functions, and is not limited to shoes used on a daily basis, but also sports shoes or sports shoes that require sports functionality such as skiing and soccer. The present invention can be widely applied to various shoes such as medical shoes for treatment and rehabilitation, training shoes for health promotion, and the like.

The invention's effect

  According to the present invention, the main requirement is to support the weight of the user while supporting the movement of the foot, and the diamond-shaped three-dimensional structure on the bottom of the insole plays an important role in weighted movement and rotation movement. Since the sole of the sole is reduced in thickness at the ridge line (cross shape) of the rhombus portion to form a depression, the stress generated by the movement of the load can be alleviated, so that the movement of the load is further facilitated. In addition, since the sole (sole) surface is supported by forming a recess in the insole-facing portion of the thumb ball, small ball, and calcaneus, the entire sole (sole) is stabilized.

  Specific examples of the present invention are shown below. The insole 1 of FIG. 2 is a perspective view from the insole surface. The line connecting the tip of the second phalanx of the second finger to the center of the calcaneal end is the ridge line, and the bottom thickness of the insole is gradually reduced in the width direction of the foot, that is, inside and outside from the ridge line. The maximum thickness of the insole bottom member varies depending on the user's muscular strength and athletic ability. For example, in the case of a sports insole, the thickness is set to about 5 mm for general sports and leisure use. The thickness of the inner and outer end surfaces of the insole is about 1 mm, but it is sufficient that the insole material can maintain appropriate male strength.

  On the other hand, in the anterior-posterior direction of the foot, the thickness of the insole is gradually reduced from the line connecting the mother and child ball and the small ball to the tip of the distal phalanx, with the toe joint shown in FIG. The thickness of the insole bottom surface member at the tip of the distal phalanx is about 1 mm, but it is sufficient that the insole material can maintain appropriate male strength.

  The insole bottom member is preferably made of cork, but is not limited to this. In addition, the core material of the insole often uses a resin plate material such as nylon or urethane, which is easily processed to match the last. However, it is also possible to bond a carbon sheet or use a hard rubber-based material, or to shape it using a 3D printer.

  It is generally used that a material on the sole side uses a foamed resin sheet. However, depending on the level of the athlete, it is also possible to select a material that can transmit the sole load directly to the shoes by using a high-strength material.

  The gradual decrease in the insole thickness of the two crosshairs on the line connecting the mother and child ball to the small ball and the line connecting the center of the calcaneal end from the tip of the tip of the second phalanx toe is the impact force when the sole touches down. Since the main purpose is to alleviate the inflammation, the gradual decrease is changed according to the exercise type and the muscular strength or exercise ability of the user, such as the bottom of the insole or the core material, the insole sole and the foam. It is suitable for use in general healthy persons, from the mother and baby ball to the small ball and from the tip of the second phalanx toe to the posterior end of the middle bone. A sufficient effect can be obtained when the gradually decreasing thickness is about several mm.

  In the present invention, in order to enhance the load stability of the sole, a method of improving the body's balance holding power by providing a taper of about 10 mm in diameter at the portion corresponding to the mother and child ball, the small ball and the calcaneal end. Is shown.

  An effect similar to the load can be obtained by using a member whose detachable bottom surface is diamond-shaped and has a rectangular shape in the height direction shown in FIG. 12 instead of the ridge line of the bottom surface of the cross-shaped insole.

  Also, by gradually reducing each ridge line shown in FIG. 13 to a detachable, bottom-diamond member having a rhombic bottom surface and a rectangular height direction, it is possible to reduce a light rainfall at the time of landing in the same manner as the thickness of the corresponding region of the insole including the insole bottom surface. effective.

  INDUSTRIAL APPLICABILITY The present invention is not limited to use in sports, and can enhance safety and convenience as a support means for improving recovery of walking exercise ability due to an accident or aging, which can reduce a user's walking burden. In addition, since the load on the ankle, the knee, and the hip joint can be reduced in order to promote the appropriate load movement of the sole when the healthy person walks, an injury prevention effect can be obtained.
