Description

  The present invention relates to a shoe having a cross band that improves the balance of walking of the body.

  Some athletic shoes and casual shoes have so-called side belts attached for the purpose of enhancing the sense of unity between shoes and feet. Patent Document 1 describes a shoe having a side belt. This shoe has a pair of side belts each attached to the sole of the shoe, and the heel of the iz portion is securely fastened to the instep with a fastening means such as a fastener provided at the other end of each side belt. That's it.

  Patent Document 2 describes a band-clamping athletic shoe that uses two bands and tightens and holds the arch portion of the foot diagonally in the toe direction. Both are intended to bring the shoe into full contact with the foot, in other words, to enhance the sense of unity with the shoe.

  Furthermore, in Patent Document 3, two straps, a first strap and a second strap, are provided as bicycle shoes, and both the straps are crossed in the vicinity of the top of the shoe upper so that the upper of the foot is crossed. Bicycle shoes have been introduced in which the strap is tightened to the shoe sole side, and the strap for tightening the upper is kept from shifting from the initial tightening position.

  The purpose of both is to enhance the sense of unity between the shoes and the feet, but the shoes described in Patent Document 1 are each provided with side covers with one end attached to both sides of the upper surface of the shoe sole. The athletic shoe described in Patent Document 2 uses a pair of two bands for each of the arch of the foot. The part is tightened so as to be pulled diagonally in the toe direction, but the basic concept does not seem to be significantly different from that described in Patent Document 1.

  Furthermore, the bicycle shoe described in Patent Document 3 uses a first strap and a second strap, and the first strap has a lower portion on the outer side of the heel portion and an inner lower portion on the fingertip portion. Between the end portions, and with the second strap, the lower portion inside the heel portion and the end portion of the lower portion outside the fingertip portion are tightened in an oblique direction, respectively, and the first strap, the second strap and the heel Part of the ankle's axial center line, and spirally wound around the instep of the foot to enhance the sense of unity between the shoes and the foot.

  However, the shoe described in Patent Document 3 is a bicycle shoe, and the strap is spiraled around the back of the foot so that the strap does not deviate from the initial state. It is intended to keep the tension of the strap permanently, but by simply winding the strap around the instep of the foot and keeping the tension of the strap permanently, shoes for walking As a result, the objective of causing normal walking muscle exercise (exercise by muscle contraction and relaxation) is not always achieved. Walking shoes require different considerations from the functions required for bicycle shoes.

In short, the shoe described in Patent Document 4 has one end of each of the left and right bands fixed to a position corresponding to the vicinity of the base of the metatarsal part, avoiding pressure on the rib part, and having a well-balanced tarsal bone part (heel) Part) is securely held. However, the shoe described in Patent Document 4 is effective for avoiding pressure on the toes, but because the toes are easily displaced with respect to the sole in the shoe, the shoe is a walking shoe. This is not necessarily the case for normal muscle exercise during walking.

  The problem to be solved is to create a shoe that deteriorates the walking balance of the body simply by unreasonably restraining the indirect contact of the foot bones and giving the foot a feeling of pressure by simply increasing the sense of unity between the shoe and the foot. It can be a problem.

  The shoe of the present invention focuses on the structure of the bones of the foot, and tightens the bones of the corresponding part with a band so as to perform the muscle movement of the foot normally. A shoe having at least two bands of a first band part and a second band part as a band to be tightened, both band parts having a base end and a terminal end on a shoe upper surface part, The band portion connects a portion corresponding to the distal inner side portion of the first metatarsal bone and a portion corresponding to the outer side portion of the radius, and the second band portion corresponds to the distal outer side portion of the fifth metatarsal bone. The part and the part corresponding to the inside part of the rib are connected.

  According to the shoe of the present invention, the outer side of the rib of the foot bone and the distal inner side of the first metatarsal bone, and the inner side of the rib and the outer side of the fifth metatarsal bone are tightened. By doing so, not only can the shoe itself be in close contact with the foot over almost the entire foot, providing a sense of unity between the shoe and the foot, but also hindering muscle movements such as the ankle and abductor muscles of the toe In order to make the vertical and horizontal arches of the foot bones function effectively, the walking balance such as smooth movement of the center of gravity and smooth kicking out is improved.

  The goal is to provide shoes that are reasonably close to the feet and provide easy-to-walk shoes with normal muscle movement of the feet, using at least two bands, with the proximal ends of each band at the distal part of the metatarsal bone. This was realized by using a corresponding shoe sole upper surface portion and a shoe sole upper surface portion corresponding to the heel portion.

  FIG. 1 is a plan view showing an embodiment of a shoe having a crossband according to the present invention, FIG. 2 is a left side view, and FIG. 3 is a perspective view showing a state in which the crossband is unwound. All the figures show shoes for the right foot. The shoe of the embodiment is a slip-on type shoe, and is composed of a shoe sole 1 in which a midsole is stacked on an outsole and a shoe cover 2, and the shoe sole 1 is joined to the lower periphery of the shoe cover 2. Both are integrated.

  In this embodiment, the shoelace cover 2 is divided into an outer outer cover portion 2a and an inner inner cover portion 2b for identification, rising from the periphery of the upper surface portion of the shoe sole 1, and the heel portion on the rear side. A toe part is formed on the front side, an upper part is formed in the middle, and a cuff 2c is formed on the upper edge. An instep upper tightening part 3 is provided on the upper part, and the upper tightening part 3 includes an outer cover part 2a and an inner cover. It joins to each cover part 2a, 2b so that the gap | interval formed between the parts 2b may be filled. The upper tightening portion 3 has a stretchable structure so that the mouth can be widened.

  A counter 4 that protects the heel portion of the foot is attached to the rear portion of the shoe hood 2. In this embodiment, the counter 4 is mounted between the front cover and the back cover, and is a portion represented by a dotted line in FIG. In the present invention, the counter 4 not only covers the buttocks of the foot and protects the buttocks of the foot, but also reaches a portion corresponding to the metatarsal bone of the inner and outer heel portion 2a (2b), and the lower edge is the shoe. Bonded to the bottom 1. Further, the toe reinforcement piece 5 provided in a cap shape on the toe part rises from the upper surface part of the shoe sole at a position corresponding to the middle foot joint joint of the outer cover part 2a, and tilts upward toward the tip of the toe part, The central part extends in a tongue shape until reaching the tip of the instep tightening portion 3, then turns to the inner heel portion 2 b side and tilts downward to reach the upper surface of the shoe sole at a position corresponding to the middle foot joint joint. ing. In the present invention, the extension of the counter 4 is important for protecting the foot bones, particularly the tarsal bones, and maintaining good walking balance of the body, as will be described in detail later. In addition, the toe reinforcement piece 5 that covers the toe portion in front of the position corresponding to the inner and outer middle foot joint joints is important for protecting the toes and maintaining the freedom of movement of the toes.

  In the present invention, at least two bands of a first band portion 7 and a second band portion 8 are provided as crossbands that connect the inner and outer upper surface portions of the shoe sole across the shoe jacket 2. The first band portion 7 has a sole upper surface portion 6b at a position corresponding to the distal inner side portion of the metatarsal bone as a base end, and an end thereof is an upper surface portion 2a at a position corresponding to the rear end of the outer side portion of the rib. Has reached.

  The second band portion 8 has a shoe sole upper surface portion 6a at a position corresponding to the distal outer side portion of the metatarsal bone as a base end, and a terminal end of the second band portion 8 at a position corresponding to the rear end of the rib inner side portion. It has reached 2b. Therefore, the 1st band part 7 and the 2nd band part 8 cross | intersect on the instep tightening part 3 of shoes. In this specification, the distinction between the base end and the end of the band portion is exclusively for convenience of explanation, and either side may be the base end.

In the present invention, “having at least two bands of the first band portion 7 and the second band portion 8” means that the first band is a band for fastening the inner and outer shoe covers. It means that two bands of the part 7 and the second band part 8 are used, and each band part includes a structure that is branched in the middle in order to enhance the decorativeness. It is.

  In the present invention, each of the first band portion 7 and the second band portion 8 is configured by connecting a toe side band portion and a heel side band portion as shown in FIG. Hereinafter, the toe side band portion of the first band portion is 7a, the heel side band portion is 7b, the toe side band portion of the second band portion 8 is 8a, and the heel side band portion is 8b. Rings 9 are attached to the release ends of the toe side band portions 7a and 8a, one end of which is fixed to the upper surface portion of the shoe sole, and each of the heel side band portions 7b and 8b whose one end is fixed to the upper surface portion of the shoe sole. On the open end side, the hook-and-loop fasteners 10 and 10 are attached to the band surface on the front side with a predetermined length across the planned fold line LL.

  Adjustment of the length of the 1st band part 7 and the 2nd band part 8 was provided in the open end of each toe side band part 7a, 8a about the 1st band part 7 and the 2nd band part 8 Each of the heel side band portions 7 b and 8 b is inserted into the ring 9, the tip is folded back, the amount of folding is adjusted, and the folded portion is stopped by the hook-and-loop fasteners 10 and 10. By adjusting the lengths of the first band portion 7 and the second band portion 8, the degree to which the shoe is in close contact with the foot can be arbitrarily adjusted.

  As the characteristics of the band portions 7 and 8, it is desirable that the band portions 7 and 8 have appropriate stretchability. According to experiments, when the toe side band portion has a width of 15 mm to 25 mm, a load of 2.5 kg is applied to the toe side band portion. Desirable results were obtained when the elongation was 4 to 8%. Moreover, both the band parts 7 and 8 may be constituted by interposing elastic materials 7c and 8c rich in elasticity compared to both sides, for example, in the middle part of the toe side band parts 7a and 8a in the longitudinal direction. desirable. By comprising as mentioned above, a band part follows the change of the foot circumference accompanying movement of feet, such as a walk, and can make local compression to a foot smaller.

  FIG. 4 shows the foot skeleton. It is said that the human body is a standard body and a skeleton is formed by 208 bones. FIG. 4A is a plan view of the skeleton of the right foot, and FIG. 4B is a side view thereof. In the figure, the skeleton of the foot is roughly as follows. That is, the talus K on the rib H is followed by the cubic bone R and the scaphoid bone S in front thereof, and three wedge bones (inner wedge bone, intermediate wedge bone, outer wedge bone) W1 in front thereof. ~ W3 are arranged, and five metatarsals (first metatarsal bone, second metatarsal bone, third metatarsal bone, fourth metatarsal bone, fifth metatarsal bone) C1 to C5 from these bones The ribs F1 to F5 are connected to the metatarsals C to form the skeleton.

  It is said that the foot bone has a unique arch structure. Because of this arch structure, even if the ground has irregularities, human feet can adapt to these irregularities and land, and can absorb and mitigate shocks when walking, running, jumping. Also, it is said that the arch also adjusts so that there is no loss in the force when kicking out the foot.

  The foot arch is formed with an inner longitudinal arch, an outer longitudinal arch, and a lateral arch. The inner longitudinal arch is a typical arch that reaches the “base” of the mother heel, with the heel as the base point and the scaphoid as the apex of the arch. The outer vertical arch runs vertically on the outer side of the foot (the little finger side) and forms a gentler arch from the heel to the “base” of the heel. The horizontal arch is a "arch" section that intersects with the inner and outer longitudinal arches when the foot is viewed from the front. In short, the basic functions of the feet such as “walking, running, jumping” are performed by keeping the vertical arch structure and the horizontal arch structure normal.

When the shoes of the present invention are worn and the inner and outer shoe covers 2a and 2b are tightened with the first band portion 7 and the second band portion 8, the band portion 7 holds the cubic bone R from above and the band portion 8 is the boat. Press the skeleton bone from above and press the foot moderately against the sole.
Further, the toe side from the distal part of the metatarsal bone can be made to perform muscle movements such as the ankle abductor muscle or the small ankle abductor more normally by not tightening the band part. As a result, the longitudinal arches and lateral arches of the foot bones function effectively, enabling smooth movement of the center of gravity and smooth kicking of the person, and improving the walking balance of the body.

  In addition, since the band portions 7 and 8 are tightened so that the cubic bone and the scaphoid bone are pressed to maintain good adhesion between the shoe and the foot, the five metatarsals are directly restrained. It will not be done. In addition, even if the foot circumference changes during the stance phase or the swing leg period in one cycle of walking (for example, from when the right heel touches the ground until the same right heel touches again), The degree of tightening is almost unchanged, and it does not loosen the foot or feel local pressure.

  According to the present invention, the counter 4 not only covers the buttocks of the foot but also reaches the proximal portion of the metatarsal bone so as to completely cover the tarsal bone. The twist of the joints of the scaphoid bone, wedge bone, and legislative bone) is suppressed, and the body's muscular motion is more normally performed, thereby further improving the walking balance of the body. The molding material for the counter may be a commonly used material such as leather, pulp or synthetic resin, and is not particularly limited.

  Each of the first band portion 7 and the second band portion 8 is configured by connecting the toe side band portions 7a and 8a and the heel side band portions 7b and 8b, and the length adjustment is performed on the finger side. The heel side band portions 7b and 8b are inserted into the ring 9 provided at the ends of the band portions 7a and 8a, folded back, the amount of folding is adjusted, and the folded portion is fastened with the hook-and-loop fastener 10 so that the shoes are in close contact with the foot. The degree to be adjusted can be arbitrarily adjusted.

  The crossband shoe according to the present invention can enhance the walking function of the body as an athletic shoe or a casual shoe.

It is a top view which shows one Example of the crossband shoes of this invention. It is a side view of the crossband shoes of this invention. It is a figure which shows the structure of a band part. It shows which position of the skeleton of the person's foot the band portion corresponds to, (a) is a plan view, (b) is a side view seen from the inside of the foot (the side of the heel).
