Description

  The present invention relates to a shoe sole for footwear, and more particularly to a shoe sole and a pad on the insole side of footwear having a high heel.

  When kicking out a person's walking motion, the heel side is lifted with the toe side touching the ground with the thumb ball and the little finger ball as a boundary. Therefore, for example, in a pump with high heel, the burden on the thumb ball is large, and it is easy to concentrate weight on the first metatarsal bone head around the thumb ball, especially when kicking out. Further, it is known that when the long thumb flexor and thumb abductor muscles are pushed up around the first metatarsal bone head at the time of kicking, the pushing force of kicking can be obtained.

On the other hand, in the conventional shoe, as the insole laid on the insole, the A function part facing the arch of the foot, the B function part facing the bottom of the second to fourth metatarsals, and the second to fourth What is provided with the C function part which faces a metatarsal bone head is known (for example, refer patent document 1). Each of these functional parts is formed so as to be higher than the other flat part of the insole, and prevents the collapse of the basic three arches of the foot structure.
JP-A-8-131207 (FIG. 4)

  However, in such a conventional shoe sole, although the basic three arches can be properly supported, each functional unit does not support up to the first metatarsal bone head. For this reason, each functional part did not act at all on the long flexor flexor muscle around the first metatarsal bone head and could not contribute to the propulsion force of the kicking. In particular, shoes with high heels have a problem that weight is not dispersed and foot pain or the like is easily induced around the first metatarsal bone head.

  However, in view of such a problem, it is also conceivable to provide a raised functional portion corresponding to the first metatarsal bone head. However, if this is simply provided, there is a risk that the comfort of the wearer may be impaired, or the burden on the foot may be increased.

  An object of the present invention is to provide a shoe sole and a pad capable of appropriately transmitting the propulsion force of kicking out without causing a sense of incongruity. .

  The shoe sole of the present invention is provided with an upper part of the insole body in the thickness direction, and includes a femoral head pressing function part that acts on the proximal part of the first metatarsal bone head in accordance with the kicking operation of walking. .

  According to this configuration, the femoral head pressing function portion is applied to the sole of the foot so as to push up the long thumb flexor and thumb abductors around the proximal portion of the first metatarsal bone head with the walking kicking motion. Can work. Thus, from an ergonomic point of view, since the thumb is pulled by the sole of the knee when kicking out due to the action on the long flexor flexor muscle, the propulsion force of kicking can be appropriately applied, and the mother Since the thumb is abducted (pulled inward) by the action on the finger abductor muscle, it can also be effective for the hallux valgus.

  The bone head pressing function part may be formed in the insole body itself or the insole, or may be configured by a pad that can be attached to the upper part of the insole body. Further, the bone head pressing function unit may be in direct contact with the sole, or may be in indirect contact with the sole through, for example, an insole. The shoe sole of the present invention is particularly useful for shoes such as boots and sandals with high heels, but the type of shoes and the height of the heels are not limited.

  In this case, it is preferable that the bone head pressing function part is formed so as to be lowered toward the distal side.

  According to this configuration, in the walking kicking-out operation, the proximal portion of the first metatarsal bone head is gradually separated from the bone head pressing function portion, following the inclination of the head head pressing function portion. As a result, the proximal portion of the first metatarsal bone head is supported until immediately before separation, so that the action on the long thumb flexor muscle and the like around the first metatarsal bone head can be appropriately continued. . In addition, women's shoes with high heels as well as general toe-down shoes can improve the comfort when wearing shoes because the head-down pressing function part can be matched to the sole shape at the time of wearing. it can.

  In this case, it is preferable that the leading edge of the bone head pressing function part that is pointed down is dislocated proximally from the position where the seed bones face and extends in the lateral width direction of the first metatarsal bone head.

  According to this configuration, since the bone head pressing function portion cannot be involved in the seed bone, for example, even if the bone head pressing function portion is made of a hard material, the wearer does not feel discomfort such as pain when kicking out. That's it. That is, it is possible to increase the degree of design freedom regarding the properties of the bone head pressing function portion. In addition, it is possible to make a functional part having a different property on the toe side of the bone head pressing functional part, and it is possible to improve the functionality of the entire shoe sole.

  In this case, it is preferable that the femoral head pressing function portion is formed to be thin toward the leading edge side that has been lowered.

  According to this structure, it becomes possible to connect the head pressing function part to the upper surface on the proximal side of the seed bone of the insole body without any step, and as a result, the comfort when wearing shoes can be further enhanced.

  In these cases, it is preferable to further include a phalange-side functional part that is provided in the upper part of the insole body in the shoe width direction and faces the phalange and has low rebound resilience with respect to the femoral head pressing functional part.

  According to this configuration, the long head finger flexor muscle or the like can be acted on by the head pressing function portion having a relatively high rebound resilience, and the sole side function portion having a relatively low rebound resilience can be used in accordance with a walking motion. Therefore, the pushing force of the kicking can be enhanced as a whole.

  In this case, it is preferable that the leading edge of the femoral head pressing function part that is pointed down is connected to the phalange side functional part with almost no step.

  According to this configuration, since there is almost no step between the femoral head pressing function part and the phalange side function part, comfort when wearing shoes can be further enhanced.

  In this case, it is preferable that the leading edge that the tip of the bone head pressing function part is lowered overlaps the phalange side function part.

  According to this configuration, it is possible to further enhance the feeling of stepping around the femoral head pressing function unit and the phalange side function unit.

  In these cases, the upper part of the midsole body is provided with a plurality of functional units including a femoral head pressing functional unit, and the plurality of functional units include the second metatarsal bone, the third metatarsal bone, and the fourth metatarsal bone. Facing the foot bone, facing the lateral arch function part formed thickly toward the inside, facing the first wedge-shaped bone and the scaphoid bone, facing the inner longitudinal arch function part formed thickly toward the inside, facing the cubic bone, Facing the outer longitudinal arch function part formed thick on the outside and the ribs, the heel receiving function part formed thinly with respect to the outer periphery of the central part, and the fifth metatarsal bone bottom, It is preferable that at least one of the bone bottom receiving function part formed so as to descend toward the distal side is included.

  According to this configuration, it is possible to reduce the load on the foot as a whole shoe, and it becomes more useful as the shoe has a particularly high heel. For example, the lateral arch function unit may draw the toes into the soles during walking. The medial longitudinal arch feature can increase the sole contact area and distribute the pressure. The outer longitudinal arch function part can contribute to the prevention of sprains. The wrinkle receiving function unit can prevent wrinkles. Further, the bone bottom receiving function unit can improve the stability of the fifth metatarsal bone bottom.

  The pad of the present invention is configured to be laid on the upper part of the midsole body of the above-described shoe sole of the present invention, and is formed by connecting two or more of the plurality of functional units integrally.

  According to this configuration, it is possible to easily provide a pad integrally formed by arbitrarily combining functional units such as the bone head pressing functional unit. This makes it possible to reduce the burden on the foot and increase the propulsive power of walking by wearing this pad even on ready-made shoes.

  According to the shoe sole of the present invention, since the femoral head pressing function part acts on the proximal part of the first metatarsal bone head with the walking motion, the long thumb flexor muscles and thumb abductors around this part are applied. The action can be performed, and the propulsion force of the kicking can be appropriately transmitted to the foot, and in addition, the comfort when wearing the shoes can be improved.

  According to the pad of the present invention, since the bone head pressing function part and the like can be easily provided on the shoe sole, the propulsion force of the kicking can be easily increased.

  Hereinafter, a shoe sole and a pad according to preferred embodiments of the present invention will be described with reference to the accompanying drawings. This shoe sole is particularly suitable for shoes with high heels, and reduces the burden on the foot from the viewpoint of ergonomics and increases the propulsive force. Therefore, first, the basic structure of the foot skeleton will be described, and then a shoe to which the shoe sole of the present embodiment is applied will be described using a pump as an example. In addition, since a pair of shoes is bilaterally symmetric, in the following description, the right foot skeleton and the shoes on the right foot side will be described.

  As shown in FIG. 1, the foot skeleton 1 includes a total of 14 phalanges 2 located at the toe portion of the foot, a tarsal bone 4 located at the rear portion of the foot, and a metatarsal bone 3 located therebetween. ,have. The metatarsal 3 includes a first metatarsal bone 6, a second metatarsal bone 7, a third metatarsal bone 8, a fourth metatarsal bone 9, and a fifth metatarsal bone 10 in order from the thumb side. . The tarsal bone 4 includes, in addition to the rib 11 and the outer cubic bone 12 adjacent thereto, in order from the rib 11 side (proximal side) to the inside of the rib 11, the talus 13, the scaphoid bone 14, And three wedge-shaped bones 15, 16, and 17 (first, second, and third wedge-shaped bones in order from the inside). There are two seed bones 18 on the sole side of the first metatarsal bone head 6a.

  As shown in FIG. 2, three basic arches, that is, a lateral arch 21, an inner longitudinal arch 22, and an outer longitudinal arch 23 are formed in the skeleton of the foot. As shown in both drawings, the lateral arch 21 is composed of first to fifth metatarsals (6, 7, 8, 9, 10). The medial longitudinal arch 22 includes the first metatarsal bone 6, the first wedge bone 15, the scaphoid bone 14, and the rib 11. The lateral longitudinal arch 23 is composed of the fifth metatarsal bone 10, the cubic bone 12 and the rib 11.

  As shown in FIG. 3, a pump-shaped shoe 31 includes an upper 32 made of cowhide and the like, and a shoe sole 33 in which the upper 32 is joined at a peripheral edge. The upper 32 has a large opening 35 in the front-rear direction (longitudinal direction) for receiving the foot from above. The shoe sole 33 includes a sole 36 serving as a shoe sole and an insole 37 provided on the upper side of the sole 36, and is formed corresponding to the shape of the sole. A heel 38 is provided on the bottom surface of the base 36 on the heel side. On the other hand, on the uppermost surface of the insole 37, as shown by a broken line in FIG. The insole 39 is made of, for example, horseskin material, and has a substantially constant thickness and is formed in a shape along the contour of the insole 37. The insole 39 is shown only in FIG.

  The insole 37 includes an insole body 41 having a planar shape that substantially matches the sole shape, and a laying unit 42 that is laid on the upper surface of the insole body 41 in the thickness direction. In a state where the laying unit 42 is laid on the upper surface of the midsole body 41 (hereinafter referred to as a laying state), the entire laying unit 42 is inclined substantially downward with respect to the horizontal plane. The shoe 31 has a heel 38 attached with a nail penetrating from the insole body 41 to the main sole 36, and is largely covered from above so as to conceal the laying unit 42 with an insole 39. Therefore, the sole contacts the laying unit 42 via the insole 39.

  As shown in FIG. 4, the laying unit 42 includes a first pad 50 (a phalange side functional unit) provided on the front half of the sole, a second pad 51 provided on the rear half of the sole, It is composed of a combination of The first pad 50 and the second pad 51 are different from each other in material properties and the like, and these are designed in consideration of the bone shape of the foot and the like so that the basic three arches 21, 22, and 23 of the foot are appropriately disposed. While being held, the burden on the foot is suitably reduced.

  As shown in FIGS. 4 and 5, the entire first pad 50 has a substantially constant thickness. The first pad 50 is laid on the upper surface of the lower front portion 43 of the midsole body 41 having a step at the front and rear intermediate positions (over the shoe width direction) so as to fill the step with almost no gap. . Therefore, the 1st pad 50 has faced each bone head (6a, 7a, 8a, 9a, 10a) of the phalange 2 and the metatarsal bone 3 widely. The first pad 50 is made of, for example, urethane foam and has a low resilience and a so-called slow recovery property. The first pad 50 can absorb the impact on the forefoot side during walking, disperse the weight load pressure appropriately, and can appropriately transmit the kicking force to the ground.

  The second pad 51 is formed to be slightly narrower than the first pad 50. The second pad 51 is laid on a substantially flat upper surface of the upper rear portion 44 of the midsole body 41, and the toe side (distal side) portion overlaps the rear side portion of the first pad 50. . The second pad 51 is made of, for example, a carbosan foam (trade name: Emsold Co., Ltd.), which is a foamed latex containing activated carbon, and is made of a material excellent in impact absorption and restoration. The second pad 51 may be either an elastic material or a non-elastic material (for example, cork), and the hardness is preferably about 5 to 25 for a JISK6301 spring type hardness tester C type, for example.

  In addition, the second pad 51 is made of a material having higher rebound resilience than the first pad 50. Accordingly, the first pad 50 having relatively low rebound resilience can suitably disperse the pressure applied to the sole in accordance with the walking motion, and the details will be described later. 71 can appropriately act on the long thumb flexor and thumb abductor muscles around the first metatarsal bone head 6a, and as a whole, the pushing force of the kick can be increased. The laying unit 42 is laid by bonding the entire lower surface of each pad 50, 51 to the upper surface of the midsole body 41.

  As shown in FIG. 6, the second pad 51 includes a plurality of functional parts (71 to 76) whose main part is an area surrounded by a broken-line circle, and a plurality of continuous parts that connect each functional part with a gentle curved surface. 78 and is integrally molded. The second pad 51 has a substantially flat upper surface (front surface), while a lower surface (rear surface) bonded to the midsole body 41 has an undulating surface, and has a plurality of functional parts (as a whole). 71-76). The plurality of functional parts (71 to 76) include a head pressing function part 71 projecting inwardly in a spire shape, a lateral arch function part 72 adjacent thereto, and an inner longitudinal arch function part 73 located inside the front and rear intermediate part. An outer vertical arch function part 74 located outside corresponding to the inner vertical arch function part 73, a bone bottom receiving function part 75 adjacent to the outer vertical arch function part 74, and a heel-side heel receiving function part 76 ,have. In the following description, FIG. 6 will be mainly described with reference to FIGS. 5, 7, and 8 as appropriate.

  The femoral head pressing function portion 71 protrudes at an acute angle so as to be further inward from the substantially linear inner line 79 of the second pad 51. The femoral head pressing function portion 71 faces the proximal portion of the first metatarsal bone head 6a, and the front edge 81 thereof is disengaged proximally from the position where the seed bone 18 faces, and the first metatarsal bone head 6a. It extends in the width direction. With this configuration, the bone head pressing function unit 71 acts to push up the long thumb flexor and thumb abductor muscles around the proximal portion of the first metatarsal bone head 6 a while avoiding the seed bone 18.

  Moreover, as shown to Fig.7 (a), the femoral head press function part 71 is formed thinly toward the distal side. Further, the femoral head pressing function portion 71 is configured to be forwardly lowered toward the distal side in the laid state, and the forwardly lowered front edge 81 has substantially no step with respect to the rear side portion of the first pad 50. And are overlapping (see FIG. 5). With such a configuration, the comfort when the shoes 31 are worn is increased, and the propulsive force at the time of kicking out walking is appropriately transmitted.

  Specifically, in the walking kicking-out operation, the proximal portion of the first metatarsal head 6a is gradually separated from the head pressing function portion 71 following the inclination of the tip downward of the head pressing function portion 71. Therefore, the proximal portion of the first metatarsal bone head 6a is supported until just before the separation. Along with this kicking-out operation, the femoral head pressing function portion 71 presses the muscles of the long thumb flexor muscles around the proximal portion of the first metatarsal bone head 6a, so that the thumb is pulled by the sole of the foot. As a result, the kicking propulsion force is given. At the same time, since the thumb is abducted by the pressing action on the thumb abductor muscle, it contributes effectively to the hallux valgus. On the other hand, since the inclination of the femoral head pressing function part 71 can substantially correspond to the shape of the sole that lowers the toe when worn, the comfort when the shoe 31 is worn is also increased.

  The lateral arch function part 72 has a function of holding the lateral arch 21 and enhancing the propulsive force of walking in cooperation with the head-head pressing function part 71. The transverse arch function part 72 mainly faces the second metatarsal bone 7, the third metatarsal bone 8, and the fourth metatarsal bone 9, and in the longitudinal direction, each metatarsal bone head (7a, 8a, It extends from the proximal part of 9a) to the distal side of the three wedge bones 15, 16, 17.

  As shown in FIG. 7 (b), the lateral arch function part 72 is formed to be thin toward the distal side in the same manner as the head pressure function part 71. Similarly, the lateral arch function portion 72 is configured to be lowered toward the distal side in the laying state, and the forwardly lowered front edge 84 is substantially the portion of the rear side of the first pad 50. They are connected and overlapped without a step (see FIG. 5). Further, as shown in FIG. 8A, the lateral arch function unit 72 is thick-walled from the outer part, which is the position of the fourth metatarsal 9, to the inner part, which is the position of the second metatarsal 7. Is formed.

  Thus, the proximal part of the 1st-4th metatarsal bone head (6a, 7a, 8a, 9a) by the front part of the 2nd pad 51 which consists of the transverse arch function part 72, the bone head press function part 71 grade | etc.,. Therefore, the burden on the metatarsophalangeal joint can be reduced even during kicking out, including normal wearing. Further, since the lateral arch function unit 72 acts on the muscle abdomen of the thumb adductor and the flexor tendon of the short finger, it is possible to further increase the propulsive force, such as the toes being pulled by the sole during walking. it can.

  The inner longitudinal arch function part 73 has a function of holding the inner longitudinal arch 22 in cooperation with the femoral head pressing function part 71, the heel receiving function part 76, and the like. The medial longitudinal arch function part 73 mainly faces the first metatarsal bone bottom 6b, the first wedge-shaped bone 15 and the scaphoid bone 14, and extends over the substantially inner half of the sole in the shoe width direction. . As shown in FIG. 8B, the inner vertical arch function portion 73 rises so that the inner edge extends upward, and is formed to be slightly thicker toward the inside as a whole. The inner vertical arch function unit 73 can appropriately secure the contact area of the sole with respect to the shoe 31 regardless of the height of the heel 38, and can distribute the weight load pressure.

  The outer longitudinal arch function part 74 has a function of holding the outer longitudinal arch 23 in cooperation with the bone bottom receiving function part 75, the heel receiving function part 76, and the like around this. The outer longitudinal arch function part 74 mainly faces the bone bottom part of the cubic bone 12, and extends substantially in the width direction of the fifth metatarsal bone 10. Although the outer vertical arch function part 74 is not shown in the drawing, like the inner vertical arch function part 73, the outer edge rises so as to expand upward, and the outer vertical arch function part 74 is formed slightly thicker toward the outside as a whole. Yes.

  Even when the inner vertical arch function part 73 is provided by the outer vertical arch function part 74, the stability in the inner and outer directions of the rib 11 can be obtained regardless of the height of the heel 38. Can contribute. Further, the outer longitudinal arch function part 74 can enhance the stability of the rib 11 in cooperation with the collar receiving function part 76. Further, the outer longitudinal arch function part 74 acts on the abdominal muscles of the little finger abductor and can be pulled outward while walking the little finger while walking, so that the degree of freedom of the little finger is increased.

  The bone bottom receiving function part 75 faces the fifth metatarsal bone base 10b, and extends in the width direction by the substantially lateral width of the fifth metatarsal bone 10. As shown in FIG. 7C, the bone bottom receiving function part 75 is formed to be thin toward the distal side in the same manner as the bone head pressing function part 71. Similarly, the bone bottom receiving function part 75 is configured to be lowered toward the distal side in the laid state. The leading edge 93 of the bone bottom receiving function portion 75 that is lowered downward is connected to the upper surface of the midsole body 41 without any level difference and constitutes a non-laying region for receiving the fifth metatarsal bone 10 with the first pad 50. ing.

  Further, as shown in FIG. 8 (b), the bone bottom receiving function part 75 rises so that the outer edge 93 expands upward as in the case of the outer longitudinal arch function part 74, and the outer side is entirely outside. It is formed slightly thick over the top. The bone bottom receiving function unit 75 can enhance the stability of the fifth metatarsal bone base 10b and appropriately maintain the lateral balance. Unlike the present embodiment, the non-laying region may be omitted, and the continuous portion 78 of the second pad 51 may be provided across the portion facing the fifth metatarsal 10, for example, On the other hand, the bone bottom receiving function part 75 may be formed thin.

  The heel receiving function part 76 faces the raised part of the rib 11 in particular, and has a size corresponding to the heel. The center part 96 of the heel receiving function part 76 is formed thinner than the outer peripheral part 97 having a substantially U shape in plan view located at the periphery of the central part 96 (FIG. 7B and FIG. 8). c)). That is, the collar receiving function part 76 is formed so as to have the central part 96 depressed and the outer peripheral part 97 raised. Therefore, when the weight is applied to the heel receiving function portion 76, the heel receiving function portion 76 is elastically deformed to have a curved shape in which the central portion 96 is dented and becomes higher from the central portion 96 toward both sides. Thereby, the blurring of the wrinkles can be prevented by the outer peripheral portion 97, and the impact at the time of landing can be suitably mitigated.

  As described above, the second pad 51 has a three-dimensional shape as a whole. Looking at the outline of the second pad 51 as a whole, the leading edges (81, 84, 93) that continue from the head pressing function part 71 to the bone bottom receiving function part 75 are formed thinly toward the distal side and are laid in the laid state. While one pad 50 and the upper surface of the insole body 41 are connected to each other without a level difference, the left and right lateral edges and the rear edge connected to the front edge (81, 84, 93) are connected to the front edge (81, 84, 93). Compared to the upper surface of the midsole body 41, the inner bottom body 41 has a predetermined thickness. The shoes to which the laying unit 42 can be applied are not limited to women's shoes such as pumps and high heels, but also include general footwear in which the bottom of the toes is lowered, in addition to boots and sandals.
