上が図られる。2. Description of the Related Art Athletic shoes are required to have cushioning properties for cushioning foot impact and light weight. Therefore, in recent years, athletic shoes provided with a columnar cushion material have been proposed (for example, US Pat. No. 4,733,483). The pillar-shaped cushion material can be reduced in weight because it is thin, but is greatly compressed up and down, so that the energy that is accumulated or dissipated is large, and therefore the cushioning property is improved.

A column-shaped or wall-shaped buffer 2 provided above the grounding portion 1 forming a tread surface to relieve impact; and provided above the buffer 2 so that a load from the buffer 2 is applied to at least substantially the entire area of the heel. And a dispersing unit 3 for dispersing. The buffer 2
Is a base 21 which is connected to the grounding portion 1 and is compressed in the vertical direction;
It has a plurality of V-shaped portions 20 formed in a substantially V-shape with an inclined portion 22 which is bifurcated and erected from the base 21 obliquely upward. The dispersion unit 3 does not need to be directly fixed to the buffer unit 2, and another member may be interposed between the buffer unit 2 and the dispersion unit 3.

ければ、主応力の方向が大きく変化しないからである。[0005] When the grounding section 1 touches the ground, an impact force F is applied to the grounding section 1 upward from the ground or the like. This impact force F is transmitted to the sole of the foot as a shock wave via the ground contact part 1, the buffer part 2, the dispersion part 3, and the like. Here, in the V-shaped portion 20, the shock wave is transmitted upward through the base 21 and
In the forked inclined portion 22, the direction of the main stress is largely changed and dispersed, and the amplitude of the shock wave is reduced by the dispersion. Therefore, the impact can be reduced, and the cushioning property is improved. Here, “formed in a substantially V-shape” means that there is a concave portion 24 that spreads downward between the V-shaped portions 20, and that there is an upper portion between the V-shaped portion 20 and the dispersion portion 3. Means that there is a space 25 that spreads out. This is because the direction of the main stress does not largely change unless these concave portions 24 and spaces 25 exist.

It is preferable that the angle is set to between 75 ° and 75 °. 75 ° tilt angle
When the inclination angle θ is smaller than 45 °, the number of the V-shaped portions 20 becomes too small.

By increasing the Young's modulus of the dispersing portion 3, the impact force from the shock absorbing portion 2 can be dispersed over substantially the entire surface of the heel, and since the Young's modulus is different, the shock wave from the shock absorbing portion 2 is reflected. It is because the power can be relieved.

It is made of resin, FRP, carbon graphite or metal plate.

十分な分散効果が得られないからである。The buffer section 2 is made of, for example, a foamed synthetic resin, and has a plurality of V-shaped sections 20 at least at the heel portion or at the rear of the shoe sole, and is compressed in the vertical direction to relieve the buffer. Here, the expression “compressed in the vertical direction” includes a case in which the image is compressed in an oblique direction, a case in which the V-shaped portion 20 is curved and shrunk vertically. The V-shaped part 20 is connected to the ground part 1 and is compressed vertically in a vertical direction. The base part 21 is bifurcated diagonally upward from the base 21 to the dispersion part 3. It is formed in a substantially V-shape with the inclined portion 22. The combined height of the grounding portion 1 and the base 21 is preferably 5 mm or more. If it is less than 5 mm, the shock wave from the road surface directly acts on the inclined portion 22,
This is because a sufficient dispersion effect cannot be obtained.

May be a wall shape instead of a pillar. Here, in the present invention, “having a columnar portion or a wall-like portion” means that a space 25 is formed between the buffer portion 2 and the dispersion portion 3 as clearly shown in the longitudinal sectional view of FIG. This means that, for example, the buffer section 2 may include a columnar section and a wall section. In addition, the arrangement of the V-shaped portions 20 is not limited to the horseshoe shape as shown in FIG. 4, and may be arranged evenly or unevenly in the rear half or all of the sole. Note that FIG.
25 formed between the V-shaped part 20 and the dispersion part 3
Is preferably 5 mm or more. If the height is not sufficient, the vertical distortion of the inclined portion 22 becomes small, and the impact cannot be sufficiently buffered.

The dispersion portion 3 is directly fixed, for example (may be indirectly fixed). The dispersion part 3 is provided above the V-shaped part 20 of the buffer part 2, and distributes the load from the buffer part 2 to at least substantially the entire area of the heel. Here, “dispersing” means dispersing the impact from the V-shaped portion 20 over a wide area due to the rigidity of the dispersing portion 3. Therefore, the dispersing portion 3 is different from the insole (inner sole). . Further, the dispersion unit 3 does not need to be connected to the buffer unit 2, and the dispersion unit 3 may be configured by a part other than the midsole. For example, the dispersion part 3 may be composed of a lunar core placed in the skin of the upper heel, or a part of the inner sole (inner sole) (for example, pulp having a certain degree of hardness). ) May constitute the dispersion unit 3. Note that an insole (not shown) is laid on the upper surface of the dispersion unit 3.

性が高まる。The dispersion section 3 is formed of, for example, a non-foaming synthetic resin plate. It is formed in the shape of a heel cup. A band-shaped bonding auxiliary portion 3c is integrally formed on the outer peripheral surface of the rising portion 3b. This adhesion auxiliary part 3c
It is made of a foamed resin having a higher affinity for the buffer portion 2 than the flat portion 3a and the rising portion 3b, and is used to enhance the adhesiveness to the buffer portion 2, and is preferably made of the same material as the buffer portion 2. Since the dispersion portion 3 is formed in a heel cup shape, it is also bonded (fixed) to the buffer portion 2 and the rising portion 3b, so that the bonding between the buffer portion 2 and the dispersion portion 3 is strengthened. In addition, since the periphery of the dispersion portion 3 is curved, the shock wave can be dispersed, so that the cushioning property is enhanced.

い。The material constituting the dispersing portion 3 includes non-foaming synthetic resin such as EVA, PU, PP, PE, etc., as well as FRP, carbon graphite, metal plate and the like. Further, the dispersion unit 3 may be a laminated plate in which two or more kinds of synthetic resins or other materials are laminated. On the other hand, the buffer 2
Is generally used as a material for forming the V-shaped portion 20. However, in order to reduce the weight of the V-shaped portion 20,
The same material as that of the dispersion unit 3 may be used. In the case of using a foamed synthetic resin, an ASKAR-C type hardness tester is used.
The angle is preferably set to about 80 to 80 degrees, more preferably about 60 to 75 degrees. On the other hand, if the buffer section 2 and the dispersion section 3 are made of the same material, the buffer section 2 and the dispersion section 3 can be integrally molded as shown in FIG. 11 or FIG. Further, as shown in FIG. 12, the shoe sole 4 may be divided into a first half and a second half.

軽量化が図られる。As described above, according to the present invention,
Since a plurality of V-shaped portions are provided on the midsole, the direction of the main stress changes greatly when an impact force propagates from the base of the V-shaped portion to the inclined portion. Therefore, the shock wave is dispersed and the amplitude of the shock wave is reduced, so that the cushioning property is improved. Also, since the buffer portion is composed of a V-shaped pillar,
Lightening is achieved.
