In the bulge 100, the proximal part 103 for supporting the mother part 26A of the foot, and the other part 104 for supporting the second to fourth metatarsal heads 28A to 32A and the minor part 34A. is formed, and a V-shaped concave portion 105 is formed between the mother portion 103 and the other portion 104 . The outer peripheral portion 102 is inclined upward with a thickness gradually decreasing toward the outer side of the bulging portion 100 .

Section S2-S2 is a cross section crossing the first metatarsal head 26A and the fifth metatarsal head 34A. The insole main body 160 of this part is equipped with the flat surface part 100A on the surface 1A, and the back surface 1B is equipped with the bulging part 100 which swells downward. The bulging part 100 has a flat body part 101 and an outer peripheral part 102 having a gradually decreasing thickness.

The S3-S3 cross-section is a cross-section that crosses the metatarsal bones 26-34. The insole body 160 of this part is equipped with the flat surface part 100A on the surface 1A, and the back surface 1B is equipped with the bulge part 100. As shown in FIG. An arc concave portion 106 in which the central portion in the width direction is concave forward in an arc shape is formed in the rear edge portion of the bulge 100 .

The cross section S4-S4 is a site corresponding to the transverse arch crossing the metatarsal bones 26 to 34, and the insole body 160 is thick at a site corresponding to the long center of the sole corresponding to a general foot, and the outside of the right foot is As the surface side faces downward, the thickness decreases gradually. In addition, on the back surface of the left and right inner and outer sides, the thickness reduction parts 72 and 74 are formed in both sides of the flat part, and it is made to allow some deformation|transformation to the left and right in the cross section S4-S4.

S5-S5 cross section is a site|part corresponding to the cuboid 18, and the insole body 160 is equipped with the cuboid support convex part 80 of maximum thickness. The surface 80A of the cuboid support convex portion 80 has a portion 3 corresponding to the navicular bone 16 (Fig. 2) from the portion corresponding to the cuboid 18 toward the left and right both edges 76. Including the lower diameter, the thickness is gradually reduced. The insole body 160 is provided with the raised edge part 78 in the outermost edge in cross section S5-S5.

The cross section S6-S6 crosses the calcaneal tubercle 12A, and is a site corresponding to the posterior end point of the calcaneus. The insole main body 160 of this part is provided with the anterior calcaneal support convex part 90 of the maximum thickness, and its surface 90A is the left and right side edges 76 from the site|part corresponding to the calcaneal tubercle 12A. Including the site|part 3 (FIG. 2) corresponding to the navicular bone 16 toward the downward direction, the thickness is gradually reduced.

S7-S7 cross section is a site|part which crosses the back part of the calcaneus 12, and corresponds to the calcaneal rear end point. The insole body 160 is relatively flat on the surface 1A side so as to support the heel corresponding to the general foot. Moreover, as for the insole main body 160, the surface 1A side moves upward toward both sides, thickness increases, and the protruding edge part 78 is provided in the outermost edge. Reduction portions 72 and 74 are formed on the rear surfaces of the left and right inner and outer sides, so that a slight horizontal deformation in the cross section S7-S7 can be tolerated.

In the cross section S10-S10 and the cross section S11-S11, the surface is raised in a portion corresponding to the cuneiform bones 20 to 24 and the navicular bones 16 constituting the medial calf.

The insole 1 of this invention supports not only the site|part corresponding to the cuboid 18 and the calcaneal tubercle 12A, but also supports it also in other parts in consideration of stability. However, it is not the same configuration as restricting the movement of the foot. Therefore, in the said cross section, the thickness reduction part 72 is provided in the insole main body 160, In the inner side of the cubic bone support convex part 80, it can sink. Therefore, even when a force acts on the site|part corresponding to the cuneiform bones 20-24 and the navicular bone 16, the insole body 160 deform|transforms by the thickness reduction part 72, and stress is relieved.

Sections S11-S11 to S13-S13 are portions corresponding to the cuboid 18 and include the cuboid support convex portion 80 of the maximum thickness. The surface 80A of the cuboid support convex portion 80 gradually decreases in thickness from the site corresponding to the cuboid 18 toward the front and back. In other words, when the foot is put in the shoe to which the insole 1 is attached and the cuboid support convex portion 80 corresponding to the cuboid 18 is placed in an upright position, the maximum stress is applied to the sole surface of the foot. make it The insole 1 has a configuration in which the stress gradually decreases as it moves back and forth from the cubic bone support convex portion 80 .

In addition, as a structure of the bottom face side of the insole 1, the site|part in contact with a shoe is flat in the site|part corresponding to the cubic bone 18, ie, the back side of the cubic bone support convex part 80. As shown in FIG. With this configuration, a reaction force always acts on the cubic bone 18 from the shoe.

Sections S12-S12 and S13-S13 are also portions corresponding to the calcaneal tubercle 12A, and are provided with an anterior calcaneal support convex portion 90 of the maximum thickness. The surface 90A of the anterior calcaneal support convex portion 90 is gradually decreased in thickness from the site corresponding to the calcaneal tubercle 12A toward the front and back. In other words, the insole 1 has a configuration in which the stress gradually decreases as it moves back and forth from the anterior calcaneal support convex portion 90 . In addition, the site|part in contact with a shoe is flat in the site|part corresponding to the calcaneal tubercle 12A, ie, on the back side of the anterior calcaneal support convex part 90. As shown in FIG. With this configuration, a reaction force from the shoe always acts on the calcaneal tubercle 12A.

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

The site is located on the outside of the cuboid support convex portion 80 and the front calcaneal support convex portion 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 thickness reduction portion 74 is provided in a portion corresponding to the outer calcaneus, and the insole 1 can sink even outside the cubic bone support convex portion 80 and the front calcaneal support convex portion 90 . has been Even when a force acts on the fifth metatarsal bone 34 of the outer calf, the insole body 160 is deformed by the thickness reduction 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 cuboid 18 is supported from below, the foot maintains a neutral position (neutral) forward and backward, and using the cuboid 18 as a point (支點), valgus is allowed as a pronation movement. In addition, supination (回外) movement is allowed as varus.

Thereby, without the insole 1 interfering with the normal movement of a joint, there is little need for a target in another site|part, and the movement of the center of gravity in front-back, left and right becomes easy. That is, the insole 1 does not constrain the foot fixedly like a cast, but the surface of the cuboid support convex portion 80 in the radial direction decreases to relieve stress, and furthermore, the thickness reduction portions 72 and 74 ) to make it easier to deform the insole (1) itself, allowing movement. The insole 1 is shaped to support a portion corresponding to the cubic bone 18 from below, and smoothly induces pronation and supination while correcting and preventing excessive distortion of the skeleton of the foot.

5 shows the arch of the sole.

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

Arch 119 includes a medial longitudinal arch 121 and lateral longitudinal arch 122, formed in the longitudinal direction of the foot, and a transverse arch 120, formed in the short direction of the foot. The transverse arch 120 is formed between the first to fifth metatarsal bones 26 to 34, as shown in FIG. 2 . In addition, the medial calf 121 is between the calcaneus 12, talus 14, scaphoid 16, three cuneiform bones 20 to 24, and first to third metatarsal bones 26 to 30. formed across The lateral calf 122 is formed between the calcaneus 12 , the cuboid 18 , and the fourth to fifth metatarsal bones 32 , 34 .

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

This calcaneus 12 is the most important part to support the user's weight (F). In the calcaneus 12, the front upper end 12B of the calcaneus serves as the force point P1, and the lower end of the calcaneus (posterior calcaneus) 12C becomes the point P2, so a moment centered on the point P2 acts on the calcaneus 12 .

In this configuration, the calcaneus anterior support convex portion 90 supports the calcaneal tubercle 12A substantially directly below the force point P1, whereby the calcaneus 12 can be stabilized. In addition, since the calcaneal tubercle 12A has a distance from the lower end 12C of the calcaneus, which is the point P2, by providing the anterior calcaneal support convex portion 90 at the site corresponding to the calcaneal tubercle 12A, a small force is required. It is possible to efficiently support the calcaneus (12).

Also in the cubic bone 18, the user's weight (F) through the calcaneus 12 acts. With respect to the cuboid 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 cuboid support convex portion 80 supports the cuboid 18 substantially directly below the power point P1, so that the cuboid 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 site corresponding to the cubic bone 18 . By providing the cuboid 18, it is possible to efficiently support the cubic bone 18 with a small force.

However, only by supporting the cuboid 18, the calcaneus 12 is difficult to stabilize, and distortion may occur in the cuboid 18, the calcaneus 12, and the joint (longitudinal cuboid joint).

Since the calcaneus 12 simultaneously constitutes both the medial calf 121 and the lateral calf 122, if the calcaneus 12 is not stable, the calcaneus cannot be maintained in a normal position. In particular, the calcaneal tubercle 12A of the front of the calcaneus 12 is, as shown in FIG. 6, the long plantar ligament connecting the middle part of the calcaneus 12 and the second to fifth metatarsal bones 28 to 34 ( 64) are positioned so that they overlap. This long plantar ligament 64 also serves to maintain the calf.

In this configuration, since the anterior calcaneal support convex portion 90 supports the calcaneal tubercle 12A via the plantar plantar ligament 64, the calcaneus 12 is stabilized and distortion of the longitudinal cubic joint can be reduced. Along with this, the calf can be brought into a normal position. Thereby, the calf functions more effectively as a spring. In particular, at night, compared to the daytime, since the function of maintaining the calf of the long plantar ligament 64 decreases, it is effective to support the long plantar ligament 64 . The anterior calcaneal support convex portion 90 includes a site 4 corresponding to the calcaneal tubercle 12A at the position where the plantar plantar ligament 64 overlaps.

The anterior calcaneal support convex portion 90 supports the long plantar ligament 64 to promote passive stabilization of the foot arch, and the long plantar ligament 64 enables the stop of the iliac crest muscle, which is important in active stabilization of the lateral calcaneus. Support the tendon (66). Here, passive stability is achieved by ligaments, and active stability is achieved by tendons (tendons). As shown in FIG. 2, the stop tendon 66 of the iliac crest, after winding around the cuboid 18, crosses the plantar from the outer edge of the foot, and the first cuneiform 20 and the first metatarsal ( 26) stops at the bottom. Further, a portion of the anterior calcaneal support convex portion 90 is located in the lower portion of the cuboid 18, and through the cuboid 18, supports the scaphoid 16. Thereby, the stationary tendon 67 of the posterior tibialis muscle, which is the main component of the active stabilization structure of the medial calf, is indirectly supported.

The stop tendon 67 of the posterior tibialis muscle extends the fascia to the first to third cuneiform bones 20 to 24, the second to third metatarsal bones 28 and 30, and the navicular bones 16. By the oblique running of these two tendons, the longitudinal arch is held in addition to the transverse arch.

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

Since the insole body 160 is configured to relieve stress by lowering the surface in the radial direction with the cubic bone support convex portion 80 as the center, the movement of the joint constituted by the calcaneus 12 is allowed. can More specifically, the anterior calcaneal support convex portion 90 is made of a relatively soft material, and the portion having the maximum thickness under the user's weight subsides, and supports the calcaneal tubercle 12A. As the anterior calcaneal support convex portion 90 sinks, the insole 1 descends in the radial direction in the front and rear left and right directions with the cubic bone support convex portion 80 as the center, and the foot with the cubic bone 18 as a point. While supporting, movement of the foot is allowed about the cuboid support convex portion 80 .

In this configuration, the anterior calcaneal support convex portion 90 abuts against the calcaneal tubercle (anterior calcaneal of the foot) 12A, and holds the medial calcaneus 121, the lateral longitudinal arch 122 and the transverse arch 120 of the foot. do.

By the convex part 90 supporting the calcaneus, it is possible to stably support the calcaneus 12, and the transverse arch 120 of the plantar, the medial calf 121, and the outer calf 122 are maintained in a natural shape. , can improve the stability and mobility of the foot.

And, in this state, that is, in a state in which the anterior calcaneal support convex portion 90 holds the medial longitudinal arch 121, the lateral longitudinal arch 122 and the transverse arch 120, the bulge 100 is, It is configured to support the first metatarsal head (parent region) 26A and the second to fifth metatarsal heads (minor region) 28A to 34A of the foot.

In this configuration, as shown in FIG. 6 , when the bulge 100 comes into contact with the middle bottom 7 of the shoe, the surface portion 100A of the bulge 100 is held upward. , by the surface portion 100A, the first to fifth metatarsal heads 26A to 34A, such as the mother tongue 26A and the small mouth 34A, are held upward, that is, the side where the toes are attached. do.

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

In general, the mid-lower of a shoe makes the heel side high and the toe side low to make walking easier. ) is likely to be crushed. Therefore, it is difficult for a toe to move, and the natural movement of a toe|toe may be inhibited, and it is difficult to obtain the stimulation of a natural movement of a toe|toe.

On the other hand, in this configuration, since the bulge 100 holds the mother tongue 26A and the small mouth 34A at a high position with respect to the middle bottom 7 of the shoe, the foot supported by the insole 1 is The inside of the shoe tends to be level, and the weight is less likely to be applied to the toe side in front of the point P3 (refer to Fig. 6), and the toe tip becomes easy to move.

In this structure, the insole main body 160 is equipped with the calcaneus front support convex part 90. For this reason, the user of the insole 1 has a high toe side in a state where the arches 120 to 122 of the plantar maintain a natural shape, and when walking or running, it becomes easy to operate so that the toes naturally grasp the ground. Therefore, when going up or down a hill or stairs, it is easy to apply a force to the toe side, and it becomes easy to obtain the stimulation of an ideal movement of the toe. By using the insole 1 by this structure, it becomes easy to suppress the fall of the physical function of a foot.

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

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

The operation of the toe gripping the ground is the so-called all of the insole 110 on which the toe is loaded, including the coccyx 36-44, the metatarsal bone 46-52, and the distal fracture bone 54-62 in FIG. ) can be easily performed when the bulging part 100 on which the mother part 26A and the small part 34A are mounted is softer.

In this embodiment, since the insole front part 110 is thin and soft compared with the bulge part 100, a toe|toe can move easily.

Therefore, it is possible to easily perform a gait motion such as holding the ground with the toes, and it is possible to increase the exercise effect. By maintaining the shape of the arch of the plantar, it is possible to secure the stability and mobility of the body while enhancing the exercise effect.

In this configuration, since the bulge 100 is formed on the back surface 1B, as shown in FIG. 6 , there is a gap between the proximal portion of the bulge 100 and the middle bottom 7 of the shoe 111) occurs. Therefore, it is easy to push the insole front part 110 of the insole 1 toward the clearance 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 mother portion 103 and the other portion 104 is thinned, and the entire insole 110 is directed toward the gap 111 . so it is easy to press

Thus, in this embodiment, while it becomes easy to bend a toe, it becomes easy to apply a force to a toe, and the operation|movement which grabs the ground with a toe|toe can be performed easily.

In addition, since the flat surface portion 100A of the bulge 100 is in contact with the plantar, it is less likely to interfere with the movement of the foot compared to the case where the concave-convex 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 mother and small portions 26A and 34A may be shifted during walking or exercise, but the bulge 100 is formed widely in the front-rear direction, The bulge 100 can support the mother ball 26A or the minor ball 34A.

As described above, the insole 1 for footwear of the present embodiment is attached to the entire calcaneus 12A of the foot in order to hold the inner longitudinal arch 121, the outer longitudinal arch 122, and the transverse arch 120 of the foot. The anterior calcaneal support convex portion 90 and the anterior calcaneal support convex portion 90 in contact with the inner calcaneus 121, the outer calcaneus 122 and the transverse arch 120 are maintained, and the parent region of the foot ( 26A) and the bulging part 100 which supports the small tool 34A, and the front part of the bulging part 100 is provided with the insole front part 110 thinner than the bulging part 100. FIG. Accordingly, it is possible to maintain the shape of the arches 120 to 122 of the plantar in a natural state to secure the stability and mobility of the body, make it easy to perform the operation of holding the ground on the toes, and to train the toes.

In this embodiment, 1 A of surfaces are flat from the insole front part 110 to the bulge part 100, and the bulge part 100 swells downward. Therefore, since the bulge 100 contacts the middle bottom 7 of the shoe, and the surface part 100A constituting the surface 1A of the bulge 100 contacts the plantar on a flat surface, the toe can be moved easily. can do.

In addition, in this embodiment, the front edge part of the bulging part 100 extends on the line which connects the 5th coaxial bone 44 from the 1st coaxial bone 36 of a foot, and the 1st coaxial bone 36 and the 2nd A V-shaped concave portion 105 is formed in the front edge portion between the coccyxes 38, and is concave backward. Therefore, it is easy to push the insole 1 in the region corresponding to the hair shaft, that is, the first coccyx 36 and the first distal fracture 54, downward, and it is easy to make the hair gripping operation to be performed. have.

In addition, in this embodiment, the circular arc recessed part 106 is formed in the rear edge part of the bulge part 100, and the width direction center part becomes concave forward. Accordingly, it is possible to reduce discomfort by making it difficult to feel the boundary of the bulge 100 in the plantar.

In addition, in this embodiment, the thickness of the outer peripheral part of the bulged part 100 decreases gradually. Therefore, since the outer periphery 102 of the bulge 100 is gradually deformable according to the body weight, it is possible to reduce the discomfort with the foot.

Moreover, in this embodiment, the cuboid support convex part 80 is arrange|positioned superimposed on the anterior calcaneal support convex part 90, and the cubic bone support convex part 80 is separated from the cuboid 18 of the foot to the navicular bone 16. ) including a portion corresponding to the left and right sides to decrease the thickness, while gradually decreasing the thickness from the portion corresponding to the cuboid 18 to the front and rear to decrease the thickness in the radial direction of the front and rear left and right decrease the Therefore, since the cubic bone support convex portion 80 is provided, the arch shape including the longitudinal cubic joint of the cubic bone 18 and the calcaneus 12 is maintained, and the movement of the foot is allowed. Since the bone 18 and the calcaneus 12 are stabilized, the distortion of the longitudinal cubic joint is reduced, and the entire tarsal bone including the cubic bone 18 and the calcaneus 12 is stabilized in a natural state. As a result, since the joint of the foot moves freely, the function of the foot can be improved.

However, the above-mentioned embodiment is one aspect of this invention, and it goes without saying that it can be suitably changed in the range which does not deviate from the meaning of this invention.

For example, in the above-mentioned embodiment, although the insole main body 160 was integrally molded, the convex-shaped part 2 and the bulging part 100 of a separate body are attached detachably to a flat insole material. it's free though Moreover, it is possible to form the unevenness|corrugation in a surface material by making the insole main body 160 into multiple layers, and attaching the convex part 2 and the bulge part 100 to an intermediate|middle layer.

Although the cubic bone support convex portion 80, the anterior calcaneal support convex portion 90 and the bulge 100 were formed as solid, the cubic bone support convex portion 80, the anterior calcaneal support convex portion 90, and the bulge portion were formed. The inside of the surfaces 80A, 90A, and 101 of (100) may be made hollow.

The shoe insole of the present invention is aimed at improving an upright posture or improving exercise function, and is not only a shoe for everyday use, but also a shoe for exercise that pursues functionality such as skiing and soccer, treatment and rehabilitation ( Suitable for a wide range of footwear, such as medical footwear for rehabilitation) and training footwear for the purpose of health promotion.
