This bulging part 100 bulges downward from the back surface (lower surface) 1B of the insole body 160. The bulging portion 100 extends along a line connecting the first stun bone 36 to the fifth stun bone 44 when viewed from the bottom. In front of the bulging part 100, the insole part 110 of the insole main body 160 is formed, and the thickness of the insole part 110 is thinner than that of the bulging part 100.

3 is a lateral cross-sectional view showing the insole 1, and FIG. 4 is a longitudinal cross-sectional view showing the insole 1. In addition, in Figs. 3 and 4, (S0-S0) to (S7-S7), (S10-S10) to (S14-S14) are in Fig. 2, (S0-S0) to (S7- Corresponds to S7), (S10-S10) ~ (S14-S14).

The S0-S0 cross-section is a cross-section crossing the vicinity of the first end bone 54 and the second to third metatarsal bones 46 and 48, and the insole body 160, that is, the entire insole 110 of the cross-section, is flat. .

The S1-S1 cross-section is a cross-section crossing the vicinity of the first to fourth stun bones 36 to 42 and the fifth end bone 62, and the bulging portion 100 is formed on the back surface 1B of the insole body 160. Equipped.

In the bulging part 100, the parental part 103 supporting the parental part 26A of the foot, and the other part 104 supporting the second to fourth metatarsal heads 28A to 32A and the small part 34A. Is formed, and a V-shaped concave portion 105 is formed between the parent earth portion 103 and the other earth portion 104. The thickness of the outer circumferential portion 102 gradually decreases toward the outer side of the bulging portion 100 and is inclined upward.

The S2-S2 cross section is a cross section across the first metatarsal head 26A and the fifth metatarsal head 34A. The insole body 160 of this part is provided with the flat surface part 100A on the front surface 1A, and the bulging part 100 which expands downward on the back surface 1B. The bulging portion 100 includes a flat body portion 101 and an outer peripheral portion 102 whose thickness decreases gradually.

The S3-S3 cross section is a cross section crossing the metatarsal bones 26 to 34. The insole body 160 of this part is provided with the surface part 100A which is flat on the surface 1A, and the bulging part 100 is provided in the back surface 1B. In the rear edge portion of the bulging portion 100, an arcuate concave portion 106 is formed in which the central portion in the width direction is concave forward in an arc shape when viewed from the bottom surface.

The S4-S4 cross section is a portion corresponding to a transverse arch crossing the metatarsal bones 26 to 34, and the insole body 160 is thick at a portion corresponding to the long core of the sole corresponding to the general foot, and the outer right foot The thickness decreases gradually due to the lower diameter toward the surface. Further, on the rear surface on the left and right inner and outer sides, thickness reduction portions 72 and 74 are formed on both sides of the flat portion, so that some deformation to the left and right in the S4-S4 cross section is allowed.

S5-S5 cross section is a part corresponding to the cubic bone 18, and the insole body 160 is provided with the cubic bone support convex part 80 of the maximum thickness. The surface 80A of the cubic bone support convex portion 80 extends from the portion corresponding to the cubic bone 18 toward the left and right edges 76 and the portion 3 corresponding to the scaphoid bone 16 (Fig. 2). Including it, the thickness is reduced by lowering. The insole main body 160 is provided with the raised edge part 78 at the outermost edge in the S5-S5 cross section.

The S6-S6 cross section is a site corresponding to the posterior end point of the calcaneal tooth across the calcaneal nodule 12A. The insole body 160 of this part is provided with the full calcaneal support convex part 90 of the maximum thickness, and the surface 90A is the left and right both side edges 76 from the part corresponding to the calcaneus nodule 12A. Towards the scaphoid bone 16, including the portion 3 (FIG. 2) corresponding to the scaphoid bone 16, the thickness is decreased gradually.

The S7-S7 cross section is a site corresponding to the posterior end point of the calcaneus 12 by crossing the posterior portion of the calcaneus 12. The insole body 160 has a relatively flat surface 1A so as to support a heel corresponding to a general foot. In addition, the insole body 160 has a protruding edge portion 78 at its outermost edge, with its surface 1A side facing upward and increasing in thickness. The thickness reduction portions 72 and 74 are formed on the rear surfaces of the left and right inner and outer sides, and the deformation to the left and right in the cross section S7-S7 is slightly allowed.

In the S10-S10 cross section and the S11-S11 cross section, the surface is raised in a portion corresponding to the sphenoid bones 20 to 24 and the scaphoid bone 16 constituting the inner calf.

The insole 1 of the present invention supports not only the portions corresponding to the cubic bone 18 and the calcaneal nodule 12A, but also supports other portions in consideration of stability. However, it is not the same configuration as restricting the movement of the foot. Therefore, in this cross section, the thickness reduction part 72 is provided in the insole main body 160, and it can sink in the inside of the cubic bone support convex part 80. Therefore, even when a force is applied to a portion corresponding to the sphenoid bones 20 to 24 and the scaphoid bone 16, the insole body 160 is deformed by the thickness reducing portion 72 to relieve the stress.

S11-S11 cross-section to S13-S13 cross-section are portions corresponding to the cubic bone 18, and are provided with the cubic bone support convex portion 80 of the maximum thickness. The surface 80A of the cubic bone support convex portion 80 is reduced in thickness from the portion corresponding to the cubic bone 18 toward the front and rear. In other words, when the foot is put in the shoe with the insole (1) in the upright position, the cuboid support convex portion 80 corresponding to the cuboid bone 18 exerts a maximum stress on the sole surface of the foot. Let it. The insole 1 is a structure in which the stress gradually decreases gradually as it moves away from the cubic bone support convex portion 80 back and forth.

In addition, as a configuration on the bottom side of the insole 1, the portion in contact with the shoe is flat in a portion corresponding to the cubic bone 18, that is, on the back side of the cubic bone support convex portion 80. With this configuration, a reaction force always acts on the cubic bone 18 from the shoe.

The S12-S12 cross section and the S13-S13 cross section are also portions corresponding to the calcaneus nodule 12A, and are provided with the full calcaneus support convex portion 90 of the maximum thickness. The surface 90A of the calcaneal frontal support convex portion 90 is reduced in thickness from the site corresponding to the calcaneal nodule 12A toward the front and rear, and gradually decreases in thickness. In other words, the insole 1 has a configuration in which the stress gradually decreases as the insole 1 moves back and forth from the full calcaneal support convex portion 90. In addition, the portion in contact with the shoe is flat at the portion corresponding to the calcaneus nodule 12A, that is, on the back side of the full calcaneal support convex portion 90. With this configuration, a reaction force always acts on the calcaneus nodule 12A from the shoe.

In the cross section S14-S14, the surface is raised in a portion corresponding to the fifth metatarsal bone 34 constituting the lateral calf tooth.

This part is located outside the cubic bone support convex part 80 and the all calcaneus support convex part 90, and there is a slight rise in consideration of stability. However, it is not the same configuration as restricting the movement of the foot. A portion corresponding to the outer calf is provided with a thickness reduction portion 74, and the insole 1 is able to subside even outside the cubic bone support convex portion 80 and the full calcaneus support convex portion 90. Has been. Even when a force is applied to the fifth metatarsal bone 34 of the outer calf, the insole body 160 is deformed by the thickness reducing portion 74 to relieve stress.

In this configuration, when the insole 1 is attached, the cubic bone 18 is supported with the cubic bone support convex portion 80 as the apex. Since the cubic bone 18 is supported from below, the foot maintains a neutral position (neutral) in the left and right back and forth, while the valgus is allowed as a pronation movement with the cubic bone 18 as the point. Along with this, varus is allowed as an extraneous exercise.

In this way, the insole 1 does not interfere with the normal movement of the joint, the necessity of the object at other sites is also small, and the movement of the center back and forth to the left and right is facilitated. That is, the insole 1 is not fixedly constrained to the foot like a cast, but the surface is lower in the radial direction from the cubic bone support convex portion 80 to relieve stress, and further, the thickness reduction portions 72 and 74 ) Is installed to make it easy to deform the insole (1) itself, allowing exercise. The insole 1 has a form that supports a portion corresponding to the cubic bone 18 from below, and smoothly induces pronation and extrarotation while correcting and preventing excessive distortion of the skeleton of the foot.

5 shows the arch of the sole of the foot.

An arch (schematically shown by a broken line) 119 is formed on the sole of the human foot when it is in a natural state while walking or running.

The arch 119 includes an inner calf 121 and an outer calf 122 formed in the long direction of the foot, and a transverse arch 120 formed in the short direction of the foot. The horizontal arch 120 is formed between the first to fifth metatarsal bones 26 to 34, as shown in FIG. 2. In addition, the medial calf tooth 121 is between the calcaneus 12, the talus 14, the scaphoid 16, the three hyoid bones 20 to 24, and the first to third metatarsal bones 26 to 30 Is formed over. The lateral calf 122 is formed over the calcaneus 12, the cubic bone 18, and the 4th to 5th metatarsal bones 32 and 34.

6 is a diagram showing the principle that the user's body weight (F) acts on the calcaneus 12 through the talus 14 from the tibia 68 when the insole 1 is mounted.

This calcaneus 12 becomes the most important part supporting the user's weight (F). In the calcaneus 12, since the calcaneus anterior upper end 12B becomes the emphasis point P1, and the calcaneus lower end (the calcaneus posterior portion) 12C becomes the point P2, the calcaneus 12 has a moment centered on the point P2. .

In this configuration, the calcaneus all support convex portion 90 supports the calcaneus nodule 12A substantially directly below the stress point P1, so that the calcaneus 12 can be stabilized. In addition, since the calcaneus nodule 12A has a distance from the calcaneus lower end 12C serving as the point P2, the entire calcaneal support convex portion 90 is provided at a site corresponding to the calcaneal nodule 12A, with a small force. The calcaneus 12 can be efficiently supported.

In the cubic bone 18, the user's body weight F acts through the calcaneus 12 as well. Regarding the cubic bone 18, since the first to fifth metatarsal heads 26A to 34A become the point P3, a moment about the point P3 acts on the cubic bone 18.

In this configuration, the cubic bone support convex portion 80 supports the cubic bone 18 substantially directly below the power point P1, so that the cubic bone 18 can be stabilized.

In addition, since the cubic bone 18 has a distance from the first to fifth metatarsal heads 26A to 34A serving as the point P3, the cubic bone support convex portion 80 is located at a portion corresponding to the cubic bone 18 By installing, it is possible to efficiently support the cubic bone 18 with a small force.

By the way, only by supporting the cubic bone 18, the calcaneus 12 is difficult to stabilize, and there is a case where a warpage occurs in the cubic bone 18, the calcaneus 12, and the joint (longitudinal joint).

Since the calcaneus 12 constitutes both the inner calf tooth 121 and the outer calf tooth 122 at the same time, if the calcaneus 12 is not stable, the calf cannot be maintained in a normal position. In particular, the entire calcaneal nodule 12A of the calcaneus 12 is a long plantar ligament connecting the middle portion of the calcaneus 12 and the 2nd to 5th metatarsals 28 to 34 as shown in FIG. 64) are located so that they overlap. This long plantar ligament (64) is also responsible for maintaining the calf.

In this configuration, since the all calcaneal support convex portion 90 supports the calcaneal nodule 12A through the long plantar ligament 64, the calcaneus 12 is stabilized and the distortion of the longitudinal cubic joint can be reduced. With that, you can put the calf to its normal position. In this way, the calf serves more effectively as a spring. Particularly, at night, since the function of maintaining the calf teeth of the long plantar ligament 64 is lowered compared to the daytime, it is effective to support the long plantar ligament 64. The full calcaneal support convex portion 90 includes a site 4 corresponding to the calcaneal nodule 12A at a position where the long plantar ligaments 64 overlap.

The full calcaneal support convex part 90 supports the long plantar ligament 64 to promote passive stabilization of the germination tooth, as well as the long plantar ligament 64, which is important for the active stabilization of the lateral calf tooth. Supports gun (66). Here, passive stabilization is achieved by ligaments, and active stabilization is achieved by tendons (tendons). As shown in FIG. 2, as shown in FIG. 2, the stationary tendon 66 of the equipment bone muscle crosses the plantar from the lateral edge of the foot after winding the circumference of the cuboid bone 18, 26) stops on the floor. Further, a part of the all calcaneal support convex portion 90 is located under the cubic bone 18 and supports the scaphoid bone 16 through the cubic bone 18. Thereby, the stop tendon 67 of the posterior tibial muscle, which is the main of the active stabilization structure of the medial calf, is indirectly supported.

The stationary tendon 67 of the posterior tibialis muscle causes the fascia to appear in the first to third hyoid bones 20 to 24, the second to third metatarsal bones 28 and 30, and the scaphoid bone 16. In addition to the transverse arch, the calf is held by the oblique running of the two tendons, the posterior tibialis muscle and the posterior tibialis muscle.

In addition, since the calcaneus 12 also constitutes a joint, it is also necessary to allow movement, since the motor function is impeded only by supporting it fixedly.

Since the insole body 160 is configured to relieve stress by having a lower diameter radially around the cubic bone support convex portion 80, it is possible to allow movement of the joints of the calcaneus 12. I can. In more detail, the full calcaneal support convex portion 90 is formed of a relatively soft material, and the portion whose thickness is maximum by the user's weight sinks to support the calcaneus nodule 12A. The entire calcaneus support convex portion 90 sinks, and the insole 1 moves downward in the radial direction of the front, rear, left and right, centering on the cubic bone support convex portion 80, and moves the foot to the point of the cubic bone 18 In addition to supporting, movement of the foot around the cubic support convex portion 80 is allowed.

In this configuration, the entire calcaneus support convex portion 90 abuts the calcaneus nodule (all calcaneus of the foot) 12A, and holds the medial calcaneal tooth 121, the lateral calcaneal tooth 122 and the transverse arch 120 of the foot. do.

The calcaneus all support convex portion 90 can stably support the calcaneus 12, so that the lateral arch 120, the inner calf 121, and the lateral calf 122 of the plantar are maintained in a natural shape. , Can improve foot stability and mobility.

And, in this state, that is, in a state in which the entire calcaneus support convex portion 90 holds the inner calcaneal tooth 121, the outer calcaneal tooth 122 and the transverse arch 120, the bulging portion 100, It is configured to support the first metatarsal head (mochi) 26A of the foot and the second to fifth metatarsal heads (minor regions) 28A to 34A.

In this configuration, as shown in Fig. 6, the surface portion 100A of the bulging portion 100 is held upward by contacting the bulging portion 100 with the middle bottom 7 of the shoe. , By the surface portion 100A, the first to fifth metatarsal heads 26A to 34A, such as the mother earth 26A and the small earth 34A, are held upwardly do.

Accordingly, the full calcaneal support convex portion 90 is in a state in which the toe is released while maintaining the arch of the foot.

In general, the mid-lower of a shoe makes it easier to walk by raising the heel side and lowering the toe side, but since the toe side is low, it is easy to apply force to the toe side when weight is applied, and the entire toe is the middle of the shoe (7 ) Is easy to be pushed down. Therefore, the toe is difficult to move, the natural motion of the toe may be impeded, and it is difficult to obtain stimulation of the natural movement of the toe.

On the other hand, in this configuration, since the bulging portion 100 holds the top portion 26A and the small portion 34A at a high position with respect to the mid-bottom 7 of the shoe, the foot supported by the insole 1 The inside of the shoe tends to be close to the horizontal, and the weight becomes difficult to be applied to the toe side in front of the point P3 (see Fig. 6), and the toe tip becomes easier to move.

In this configuration, the insole body 160 includes a protrusion 90 for supporting all calcaneus bones. For this reason, the user of the insole 1 becomes easy to operate so that the toe side is raised in a state where the natural shape of the plantar arches 120 to 122 is maintained, and the toe naturally grasps the ground when walking or running. Therefore, when going up and down a hill or stairs, the force is easy to enter the toe side, and the toe is easy to obtain the stimulation of the ideal exercise. By using the insole 1 according to this configuration, it becomes easy to suppress the decrease in the physical function of the foot.

You can train your toes just by walking in the shoes equipped with the insole (1) of this configuration. In particular, in this configuration, since the insole 1 is also provided with the cubic bone support convex portion 80, the skeletal balance of the foot is arranged, stability and mobility are further improved, and training is further facilitated.

In this configuration, since the front of the insole 110 is thinner than the bulging portion 100, the degree of freedom of the toes in front of the first to fifth distal bones 54 to 62 of the foot is further increased.

The motion of the toe to hold the ground is all the so-called insoles 110 on which the toes are loaded, including the stun bones (36 to 44), the metatarsal bones (46 to 52), and the ending bones (54 to 62). ) Can be easily performed when it is softer than the bulging portion 100 on which the mother earth member 26A and the small earth member 34A are mounted.

In the present embodiment, the insole front portion 110 is thinner and softer than the bulging portion 100, so that the toe can be moved easily.

Therefore, it is possible to easily perform a walking motion such as holding the ground with a toe, and an exercise effect can be enhanced. By maintaining the shape of the arch of the plantar, it is possible to increase the exercise effect while ensuring body stability and mobility.

In this configuration, since the bulging portion 100 is formed on the back surface 1B, as shown in Fig. 6, a gap is formed between the proximal portion of the bulging portion 100 and the middle bottom 7 of the shoe. 111) occurs. Therefore, it is easy to push the insoles 110 of the insoles 1 toward the gap 111 from above. In addition, a V-shaped concave portion 105 is also formed in the bulging portion 100, and the gap between the parent jig portion 103 and the other jig portion 104 becomes thin, and the entire insole 110 of the mojiro was directed toward the gap 111. It is easy to press.

As described above, in the present embodiment, the toe becomes easier to bend, and the toe becomes easier to apply force, and the operation of holding the ground with the toe can be easily performed.

Further, in the bulging portion 100, since the flat surface portion 100A contacts the plantar, it is difficult to hinder the movement of the foot compared to the case where the uneven shape contacts the plantar.

On the other hand, since it is difficult to interfere with the movement of the foot, there is a possibility that the position of the parental region 26A or the small region 34A may be shifted during walking or exercise, but the bulging portion 100 is widely formed in the anteroposterior direction, The bulging portion 100 is capable of supporting the mother earth 26A and the small earth 34A.

As described above, in order to maintain the inner calf tooth 121, the outer calf tooth 122, and the lateral arch 120 of the foot, the shoe insole 1 of the present embodiment pertains to the entire calcaneus 12A of the foot. In a state in which the all calcaneal support protrusions 90 and the all calcaneal support protrusions 90 in contact with each other hold the inner calcaneal tooth 121, the outer calcaneal tooth 122 and the transverse arch 120, the parent region of the foot ( 26A) and the bulging part 100 which supports 34 A of small parts are provided, and the insole whole 110 thinner than the bulging part 100 is provided in front of the bulging part 100. Accordingly, the shape of the arches 120 to 122 of the plantar can be maintained in a natural state to ensure stability and mobility of the body, making it easier to perform the motion of holding the ground on the toes, and training on the toes.

In this embodiment, the surface 1A is flat from the insole front part 110 to the bulging part 100, and the bulging part 100 bulges downward. Therefore, since the bulging portion 100 contacts the mid-bottom 7 of the shoe, and the surface portion 100A forming the surface 1A of the bulging portion 100 contacts the plantar on a flat surface, the toe is easily moved. can do.

In addition, in this embodiment, the front edge part of the bulging part 100 extends on a line connecting the first stun bone 36 to the fifth stun bone 44 of the foot, and the first stun bone 36 and the second The front edge portion between the stun bone 38 has a V-shaped concave portion 105 and is concave rearward. Therefore, it becomes easy to push the insole 1 of the moji, that is, the area corresponding to the first stun bone 36 and the first end bone 54 downward, and make it easier to make the motion of holding the ground on the moji. have.

Further, in the present embodiment, an arcuate concave portion 106 is formed at the rear edge portion of the bulging portion 100, and the central portion in the width direction is concave forward. Therefore, it is difficult to make it difficult to feel the boundary of the bulging portion 100 on the plantar, thereby reducing a sense of discomfort.

In addition, in this embodiment, the thickness of the outer peripheral part of the bulging part 100 decreases gradually. Therefore, since the outer circumferential portion 102 of the bulging portion 100 can be gradually deformed according to the body weight, the feeling of discomfort in the foot can be reduced.

In addition, in this embodiment, the cubic bone support convex part 80 overlaps each other on the all calcaneal support convex part 90, and the cubic bone support convex part 80 is the scaphoid bone 16 from the cubic bone 18 of the foot. ), including the area corresponding to the left and right sides, to decrease the thickness, and decrease the thickness from the area corresponding to the cubic bone 18 toward the front and rear, and decrease the thickness in the radial direction of the front and rear Decrease. Therefore, since the cubic bone support convex portion 80 is provided, the arch shape including the longitudinal cubic joint of the cuboid bone 18 and the calcaneus 12 is held, and the movement of the foot is allowed, Since the bone 18 and calcaneus 12 are stabilized, the distortion of the longitudinal cubic joint is reduced, and the entire ankle bone including the cubic bone 18 and the calcaneus 12 is stabilized in a natural state. As a result, since the joints of the feet move freely, the function of the feet can be improved.

However, it goes without saying that the above-described embodiment is an aspect of the present invention, and can be changed suitably within a range not departing from the gist of the present invention.

For example, in the above-described embodiment, the insole body 160 is integrally molded, but the separate convex portion 2 and the bulging portion 100 are detachably attached to a flat insole material. It is okay to do it. Further, it is possible to form irregularities in the surface material by using the insole body 160 as a plurality of layers and attaching the convex portion 2 and the bulging portion 100 to the intermediate layer.

Although the cubic bone support convex part 80, the calcaneus all support convex part 90, and the bulging part 100 were formed in a solid shape, the cubic bone support convex part 80, the calcaneus all support convex part 90, and the bulge part The inside of the surface (80A, 90A, 101) of (100) may be made hollow.

The shoe insole of the present invention is aimed at improving the standing posture and improving the motor function, and not only shoes for everyday use, but also shoes for exercise pursuing functionality such as skiing or soccer, treatment or rehabilitation ( It is widely registered for various types of shoes, such as shoes for medical use for rehabilitation purposes, and shoes for training for the purpose of health promotion.
