JP-A-11-113609 (paragraph number 0004)

  Conventional shoes that are easy for a pregnant woman to wear are configured as described above. When putting on and taking off shoes, it was easy to put on and take off the shoes by loosening or tightening the belt. However, the shoe sole was not particularly considered.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a shoe sole that is easy for a pregnant woman to walk.

  The shoe sole according to the present invention includes a first reinforcing belt portion provided in a portion corresponding to the lateral arch of the sole from the metatarsal arch of the shoe sole, A second reinforcing band portion provided on the toe side from the foot arch, and the first and second reinforcing band portions extend from the heel side to the toe side.

  The shoe sole is provided with a first reinforcing band portion and a second reinforcing band portion extending from the heel side to the toe side across the metatarsal arch, so that the shoe sole does not twist in the lateral direction and the first reinforcement is provided. It is easy to move the center of gravity along the second reinforcing band from the band.

  As a result, it is possible to provide a shoe sole that is easy for a pregnant woman to walk.

  Preferably, the first reinforcing band portion extends from the inner side surface of the shoe toward the outer side surface, and the second reinforcing band portion extends from the outer side surface of the shoe toward the inner side surface.

  More preferably, a 1st reinforcement belt | band | zone part is provided in the outer side of shoes with respect to a 2nd reinforcement belt | band | zone part.

  According to one embodiment of the present invention, the shoe sole includes a tip portion provided with the second reinforcing band portion, a heel portion, and a center portion provided between the tip portion and the heel, The outside of the first reinforcing band is formed of a material that is less slippery than the other parts.

  Note that the shoe sole may be provided with a groove along the metatarsal arch, and the foot placement portion of the shoe sole may be provided with a groove along the metatarsal arch. .

  Moreover, it is preferable that the height of the heel side of the shoe sole is 20 mm higher than the height of the toe side.

  An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an overall configuration of a shoe 50 when a shoe sole according to an embodiment of the present invention is applied to a maternity shoe. Referring to FIG. 1, a pregnant woman's shoe 50 includes a shoe sole 10 and an upper portion 51 provided on the shoe sole 10. The shoe sole 10 is not flat, and the toes are located higher than the plane (shown by diagonal lines in the figure). When the toe height is a and the heel height is b, the maternal shoe sole 10 has a = about 10 mm and b = about 30 mm, and the difference is preferably about 20 mm.

  This is because a pregnant woman generally has a center of gravity behind, so that it is preferable for walking that the front side is lower by about 20 mm than the heel side.

  Next, the details of the shoe sole 10 will be described. 2A is a plan view showing a shoe sole 10 of a maternity shoe (for the left foot), and FIGS. 2B and 2C are respectively BB and C- in FIG. 2A. FIG.

  Referring to FIG. 2, the shoe sole 10 of the maternity shoe includes a shoe sole portion 11, inner and outer side wall portions 21 a and 21 b provided continuously to the shoe sole portion 11, and the opposite side of the shoe sole portion 11. And a placement portion 22 for placing a foot. Here, the inner side refers to the side where the big toe exists, and the outer side refers to the opposite side.

  The shoe sole portion 11 includes a distal end portion 12, a metatarsal portion 13 where the metatarsal arch of the foot is located, a central portion 14, and a heel portion 15, which are provided on the heel side sequentially from the distal end portion 12. ing. A step portion 16 is provided between the central portion 14 and the flange portion 15.

  Further, the metatarsal bone portion 13 is lower by about 1 to 2 mm than the distal end portion 12 and the central portion 14 (t = about 1 to 2 mm in FIG. 2). That is, the shoe bottom surface is basically a surface on which the metatarsal bone portion 13 is provided, and rubber is attached to the distal end portion 12, the central portion 14, and the heel portion 15 thereon.

  Next, the metatarsal arch will be described. FIG. 3 is a anatomical diagram of a foot bone. The bone of the foot is roughly divided into three regions, that is, a phalanx region (foot rib) region B, a metatarsal region C, and a tarsal bone region D. The metatarsal arch 30 in front of the foot is a so-called arch of the instep, and is not a true arch but changes by applying a load. In the case of a pregnant woman, the metatarsal arch 30 is crushed by its own weight during walking. The lateral arch 31 at the foot has no arch change due to its own weight.

  The metatarsal portion 13 is formed in a curved shape having a predetermined width along the metatarsal arch 30 from the outer central portion of the shoe sole to the base of the inner thumb foot. Curved grooves 13a and 13b are provided, so that pregnant women can easily bend their legs at the metatarsal arch 30 during walking.

  A first reinforcing band portion 17 is provided from the heel side to the toe side of the shoe sole 10 at a substantially central portion of a portion corresponding to the lateral arch 31 of the sole 10 from the metatarsal arch 30 of the shoe sole 10. Yes. The first reinforcing band portion 17 is formed in a straight line that is shifted from the inner side surface to the outer side surface of the shoe, that is, slightly outward from the substantially center of the upper portion of the heel portion 15. Further, the second reinforcing band having substantially the same shape as that of the first reinforcing band part 17 is also provided from the metatarsal arch 30 to the distal end part 12 at a position shifted to the inside of the shoe sole 10 with respect to the first reinforcing band part 17. A portion 18 is provided. The direction of the 2nd reinforcement belt | band | zone part 18 is extended in the reverse direction to the 1st reinforcement belt | band | zone part 17, ie, the inner surface from the outer side surface of shoes.

  These first and second reinforcing band portions 17 and 18 are formed of rubber having a hardness equal to or higher than that of at least the distal end portion 12, the metatarsal bone portion 13, the central portion 14, and the heel portion 15. ing. The reinforcing band portions 17 and 18 may be formed by first forming grooves that can accommodate these band portions, and affixing the band portions in the grooves leaving the groove portions around. Also in this case, the surface of the belt portion is the same height as the peripheral tip portion 12, the central portion 14, and the like.

  The first and second reinforcing band portions 17 and 18 are provided so that a pregnant woman can easily move the weight of the center of gravity along this line. That is, the pregnant woman can move the center of gravity along this line by using the first and second reinforcing belt portions 17 and 18.

  Here, the 1st reinforcement belt | band | zone part 17 and the 2nd reinforcement belt | band | zone part 18 are provided on both sides of the metatarsal bone part 13, without mutually continuing. The reason for this configuration is that if the first and second reinforcing band portions 17 and 18 are provided in succession, the shoe sole 10 extends along these band portions 17 and 18. , 18 as a center to twist in the lateral direction.

  Next, details of the configuration of the shoe sole 11 will be described. The shoe sole 11 includes, on the toe side of the metatarsal bone portion 13, a distal end portion 12 provided with a second reinforcing band portion 18, a heel portion 15, and a central portion 14 provided between the distal end portion and the heel portion. including. The distal end portion 12 is divided into an outer distal end portion 12 a and an inner distal end portion 12 b by the second reinforcing band portion 18. The outer tip 12a and the inner tip 12b are made of the same material rubber, but the pattern is different as shown in FIG. 2, the outer tip 12a is corrugated, and the inner tip 12b is It has a round shape.

  The collar portion 15 is also made of rubber made of the same material as the tip portion, and the pattern thereof is the same as that of the inner tip portion 12b. Further, the inside of the first reinforcing band portion 17 of the central portion 14 is also made of the same material rubber. In addition, the collar part 15 is comprised with the material which can absorb an impact.

  The outer sides 14c and 14e of the first reinforcing band portion 17 of the central portion 14 are preferably made of non-slip rubber that is less slippery than other portions such as the tip portion 12 and the flange portion 15. Such a material is relatively soft and does not slip even in rainy weather or during water work.

  As described above, since the outer side of the first reinforcing band portion 17 of the center portion 14 of the shoe sole is formed of rubber that is less slippery than the tip portion 12 and the heel portion 15, when the pregnant woman walks, first when landing on the heel portion 15 It is possible to land smoothly so that it slides, and can be firmly fixed outside the central portion 14, and the next step can be smoothly advanced from the toes.

  Next, the center part 14 is demonstrated. The central portion 14 includes a circular arch portion 14a provided inside thereof, an inner first central portion 14b provided between the arch portion 14a and the metatarsal portion 13, an arch portion 14a, and a heel portion. The first outer side provided between the inner second central part 14d provided between the inner side 15 and the inner first central part 14b and the inner second central part 14d with the first reinforcing band part 17 interposed therebetween. A central portion 14c and a second outer central portion 14e are included.

  The inner first central portion 14b and the outer first central portion 14c have a plurality of oblique linear patterns extending from the arch 14a toward the little toe of the foot, that is, in the upper right direction in FIG. The portion 14d and the outer second central portion 14e have a plurality of linear patterns extending in a direction orthogonal to the inner first central portion 14b and the outer first central portion 14c.

  Thus, in the center part 14 of the shoe sole, since the pattern is such that the toe side and the heel side of the arch part 14a are orthogonal to each other, walking becomes easier.

  Here, the outer first center portion 14c and the outer second center portion 14e are patterns orthogonal to each other. However, the present invention is not limited to this, and both of these portions may be formed in a chevron (V-shaped) pattern. Good. This state is shown in FIG. In this way, the same anti-slip effect as the orthogonal pattern described above can be obtained with one pattern. Moreover, this chevron pattern is good also considering not only both the outer 1st and 2nd center parts 14c and 14e but the outer 2nd center part 14e as this pattern.

  Next, the relationship between the 1st and 2nd reinforcement belt | band | zone parts 17 and 18 and the gravity center movement at the time of a pregnant woman's walk is demonstrated. FIG. 5 shows the soles of the pregnant woman's feet when the pregnant woman places his / her feet on the mounting portion 22. The arrows in the figure indicate the weight shift locus during walking. Paying attention to the movement of the center of gravity of a pregnant woman when walking, first touch the ground with a heel, the center of gravity moves to the outside of the foot, shifts from the fifth metatarsal bone head to the first metatarsal bone head, Pull out from the tip of the first finger).

  Therefore, the shape of the first and second reinforcing band portions 17 and 18 is preferably a shape along the weight shift during walking so that the center of gravity shifts. Then, the center of gravity moves also in the width direction of the foot, and a sense of stability is obtained.

  Next, the foot placement portion 22 of the shoe sole 10 will be described. 6 (A) is a plan view showing the foot placement portion 22 of the shoe sole 10, and FIG. 6 (B) is a cross-sectional view of a portion indicated by VB-VB in FIG. 2 (A). FIG. 6C is a cross-sectional view of a portion indicated by an arrow CC in FIG.

  Referring to FIG. 6A, the foot placement portion 22 of the shoe sole 10 has three parallel grooves 25a to 25c provided along the metatarsal arch 30 shown in FIG. Is provided. With these three grooves 25a to 25c, the pregnant woman can easily bend the distal end portion 12 at the metatarsal arch 30 when the pregnant woman is walking, and the center of gravity can be easily moved.

  Further, as shown in FIG. 6C, a rising portion 24 is provided around the foot placement portion 22. This makes it easier for the pregnant woman to position the foot on the placement portion 22.

  Next, a cross section of the shoe sole 10 will be described. With reference to FIG. 6 (B), the rubber | gum mentioned above is each affixed on the front-end | tip part 12, the center part 14, and the heel part 15 of the bottom face of a shoe sole. Accordingly, the bottom surface of the shoe sole 10 is configured to be easy to walk without slipping.

  In addition, in the said embodiment, as shown in FIG. 2, although the example which provided the linear level | step-difference part 16 in the boundary part of the center part 14 and the heel part 15 of a shoe sole was demonstrated, it is not restricted to this. The boundary portion between the central portion 14 and the flange portion 15 may be arcuate. The shape of such a shoe sole is shown in FIG. Here, only the lower part of the metatarsal bone is shown.

  As shown in FIG. 7, in this embodiment, the inner second central portion 14 f and the outer second central portion 14 g are separated by an arc-shaped boundary line without having a step between the flange portion 15. It has been.

  Moreover, this boundary part is good also as V shape, as shown with a dotted line in FIG.

  In addition, as shown in FIG. 4, it is good also considering the outer side 1st and 2nd center parts 14c and 14g as the same chevron pattern.

  Moreover, since the collar part 15 is a place which contact | abuts to the ground first at the time of a walk, abrasion is quick. Therefore, when this portion of the pattern is worn, it is time to replace the shoe sole. Therefore, the heel part 15 becomes a standard indicating the degree of wear of the shoe sole.

  In the above-described embodiment, the case where the shoe sole according to one embodiment of the present invention is applied to a shoe for a pregnant woman has been described. However, the present invention is not limited thereto, and may be applied to the shoe sole of a child's shoe. .
