Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to those submitted on September 28, 2017 Japanese Patent Application No. 2017-188242 and submitted on June 28, 2018 Japanese Patent Application No. 2018-122900 whose entire disclosures are hereby incorporated by reference.

BACKGROUND

The present disclosure relates to a sole structure for shoes and a shoe having such a sole structure.

A sole structure for shoes is disclosed, for example, in Japanese Patent Laid-Open Publication No. 2014-144170. The sole structure includes a plurality of first protrusions projecting downwardly from a bottom surface of a sole body and spaced apart from each other, and a plurality of second protrusions extending from an upper surface of the sole body upward toward the sole of a wearer of the shoes (in FIG Hereinafter merely referred to as "carrier") project and are spaced from each other. Each of the first elevations is arranged perpendicularly opposite a second elevation assigned to it, the sole body being arranged between them. Each of the first bumps has a lower hemispherical end such that the lower end contacts the ground with a relatively small area. In this sole structure, the contact area between the first elevation and the ground is substantially the same as the contact area between the second elevation and the sole of the wearer.

SUMMARY

According to the sole structure of Japanese Patent Laid-Open Publication No. 2014-144170 For example, upon ground contact of a leg of the wearer (the sole structure), a reaction force exerted from the ground to the sole structure is transmitted from the first bumps via the sole body to the second bumps. As a result, the reaction force is transmitted to the sole of the wearer.

In the sole structure of Japanese Patent Laid-Open Publication No. 2014-144170 For example, the lower end of each first land with a relatively small area contacts the ground, and the area of contact between the first land and the land is substantially the same as the area of contact between the second land and the sole of the wearer. In this embodiment, the reaction force generated at ground contact tends to be distributed during the transmission from the first bumps to the second bumps. Therefore, the reaction force can not be accurately transferred from the second bumps to portions of the sole of the wearer. As a result, the wearer can not detect the pressure differences transmitted to the portions of his sole when the foot contacts the ground, and therefore can not easily control his body movement by timely detecting the load applied to each portion of the sole of the foot when in contact with the ground.

Against this background, therefore, an object of the present disclosure is to enable the wearer to recognize in good time the stress exerted on each section of the sole of the foot when in contact with the ground, so that he can effortlessly control his body movement.

To achieve the object, a first aspect of the present disclosure is directed to a sole structure for shoes. The sole structure includes a sole body supporting an entire sole of a wearer's foot; a plurality of lower protrusions projecting downwardly from a lower portion of the sole body in the bottom direction and spaced apart from each other; and a plurality of upper protuberances projecting upwardly from an upper portion of the sole body toward the sole of the wearer, each of the upper protuberances being disposed on an upper surface of the sole body and overlapping with a lower elevation associated therewith, each of the lower ones Bumps has at its lower portion in contact with the ground passing first area and each of the upper bumps at its upper portion has a coming into contact with the sole of the wearer second region which is smaller than the first region.

In the first aspect, a reaction force is exerted from the ground to the lower bumps when the wearer's foot touches the ground during its movement, such as walking, running, or jumping, and this reaction force is applied from the lower bumps over the upper bumps the top of the sole body 3, which overlap each with the lower elevations, transmitted to the sole of the foot F of the wearer. Since the second regions of the upper bumps are smaller than the first regions of the lower bumps, the reaction force generated upon contact with the ground is concentrated from the first regions to the second regions. Thereby, the reaction force is transmitted as an increased pressure from the second regions of the upper elevations to the areas of the sole of the wearer. Thus, the wearer can recognize the pressure differences which, when in contact with the ground, affect the sections of his Sole of the foot are transferred. Therefore, in the first aspect, the wearer can easily control his body movement by timely detecting the load applied to each portion of the sole of the foot when in contact with the ground.

A second aspect is an embodiment of the first aspect. In the second aspect, each of the lower protrusions is substantially columnar-shaped, and a respective bottom surface of the upper protrusions serves as a first region.

In the second aspect, the first portions are formed as relatively wide, flat surfaces, whereby the reaction force from the ground can be easily transmitted to the first portions. Thereby, the reaction force generated upon contact with the ground can be appropriately transmitted from the first areas to the second areas.

A third aspect of the present disclosure is an embodiment of the first aspect. In the third aspect, the second portions of the upper protuberances are formed differently in size depending on their respective positions with respect to portions of the sole of the wearer.

In the third aspect, the reaction force generated upon contact with the ground can be appropriately transmitted to portions of the sole of the foot. In particular, excessive pressure possibly applied to a pain-sensitive portion of the sole F can be regulated.

A fourth aspect of the present disclosure is an embodiment of the first aspect. In the fourth aspect, depending on their respective position, the upper elevations are of different heights with respect to portions of the sole of the wearer.

In the fourth aspect, the reaction force generated upon contact with the ground can be appropriately transmitted to the portions of the sole of the foot. In particular, excessive pressure possibly applied to a pain-sensitive portion of the sole F can be regulated.

A fifth aspect is directed to a shoe with a sole structure according to one of the aspects one to four.

In the fifth aspect, shoes can be provided with the same advantages as those of the first to fourth aspects.

A sixth aspect of the present disclosure is an embodiment of the fifth aspect. In the sixth aspect, the shoe further includes a shaft attached to an upper surface of the sole structure, the shaft including a shaft body and an insert integrated into the shaft body.

In the sixth aspect, the shoe has the shaft with the shaft body and the pad, and therefore, the shoe can be made easier than a shoe without pad.

A seventh aspect is an embodiment of the fifth or sixth aspect. In the seventh aspect, the shoe further includes an insole disposed on the upper elevations.

In the seventh aspect, the insole is disposed on the upper elevations. As a result, the insole is located between the sole structure and the sole of the wearer. In particular, the upper elevations over the insole come into contact with the sole of the foot. Therefore, for example, even with excessive pressurization of the sole of the foot by the upper elevations, the insole can regulate the pressure on the sole of the foot.

According to the present disclosure, the wearer can effortlessly control his body movement by timely detecting the load applied to each portion of the sole of the foot when in contact with the ground.

The upper edge section 5 has one above the upper end of the sole body 3 located top 5a on which the outer circumference of the sole body 3 encloses. The upper edge section 5 has a curved front wall 6 at its front end and a curved rear wall 7 at its rear end.

As 2 and 3 show, points the sole 1 a variety of lower elevations 11 on. Each of the lower elevations 11 has the shape of a quadrangular prism, which has a square shape in cross section, for example, and from the underside of the sole body 3 projecting downwards in the direction of the bottom G. In particular, each lower elevation points 11 a lower section on that under the bottom 4a of the lower edge section 4 is arranged. The lower elevations 11 are spaced from each other.

Two adjacent lower elevations 11 form a groove 12 between themselves. The groove 12 is one of the bottom surfaces of the lower elevations 11 upward recess. The groove 12 has a smaller width and depth than the lower elevations 11 on.

As 1 and 3 show, points the sole 1 a variety of upper elevations 13 on. Each of the upper elevations 13 stands from the upper portion of the sole body 3 in the direction of the sole of the foot F of the carrier. Every upper elevation 13 has a pedestal in particular 13a and a tip end integrally formed with the socket 13b , The base 13a has the shape of a quadrangular prism, which is square in cross-section, for example, and has a height h0 from the upper portion of the sole body 3 so that it is essentially flush with the top edge section 5 concludes. The top end 13b has a height h1 . h2 or h3 from the top of the socket 13a up and tapering towards the top. Every upper elevation 13 in particular has one above the top 5a of the upper edge section 5 arranged upper section. In a preferred embodiment, the tip end 13b in cross section a hemispherical vertex on.

The upper elevations 13 are spaced apart, and each of the upper elevations 13 is in cross section with an associated lower elevation 11 arranged in pairs. In particular, each of the upper elevations overlaps 13 on the top of the sole body 3 with an associated lower elevation 11 ,

As 3 and 4 show, each of the lower elevations in its lower portion has a first area R1 on which is in contact with the ground G (a ground or a floor). Each of the first areas R1 is in particular a bottom surface of the quadrangular, prism-shaped lower elevation 11 and has sides that each have a dimension in plan view a1 to have. Each of the upper elevations 13 has a second area in its upper section R2 on which one with the sole of the foot F the wearer comes into contact. Each of the second areas R2 has in plan view substantially the shape of a square whose sides have the dimensions b1 . b2 or b3 which are smaller than the dimension a1 are. The second areas R2 the upper elevations 13 are especially smaller than the first areas R1 the lower elevations 11 ,

In 5 is an area that has a ball of foot and a heel of the sole of the foot F of the carrier, dotted hatched as area X represented, and an area outside the area X (For example, an area that is one of the arch of the sole of the foot F corresponding section F is included) with diagonal lines as one area Y hatched.

As 3 shows are the areas R2 the upper elevations 13 depending on the sections of the sole of the foot F of the carrier of different sizes. As well as in 4 In particular, each of the second areas has shown R2 the upper elevations 13 in that area X Pages with the dimension b1 on. On the other hand, each of the second areas R2 the upper elevations 13 in that area Y Pages with the dimensions b2 or b3 on. The dimension b1 is larger than the dimensions b2 and b3 , The dimension b2 is larger than the dimension b3 , Since the dimensions are so different, have the upper elevations 13 in that area X larger second areas R2 on as the upper elevations 13 in that area Y , In particular, the upper elevations point 13 in that area X a larger contact area with the sole of the foot F of the wearer on as the upper elevations 13 in that area Y ,

As 3 shows the upper elevations point 13 depending on the sections of the sole of the foot F the wearer different sizes. In particular, the upper elevations point 13 in that area X a height h0 + h1 on. On the other hand, the upper elevations point 13 in that area Y a height h0 + h2 or h0 + h3 on. The height h1 is smaller than the heights h2 and h3 , The height h2 is smaller than the height h3 , Since the heights differ in this way, the upper elevations are 13 in that area X smaller than the upper elevations 13 in that area Y ,

[Advantages of the Embodiment]

If in the sole formed as described above 1 the foot of the wearer during its movement, such as walking, running or jumping, in contact with the ground G occurs, a reaction force acts from the ground G on the lower elevations 11 and is from the lower elevations 11 over the upper elevations 13 on the top of the sole body 3 , which deals with the relevant lower elevations 11 overlap, on the sole of the foot F transmitted by the carrier. Because the second areas R2 the upper elevations 13 smaller than the first areas R1 the lower elevations 11 are, the reaction force generated upon contact with the ground from the first areas R1 to the second areas R2 concentrated. Thus, the reaction force becomes an increased pressure from the second regions R2 the upper elevations 13 on the sections of the sole of the foot F transmitted by the carrier. As a result, the wearer can recognize the pressure differences which, when in contact with the ground, affect the sections of the sole of his foot F be transmitted. Thus allows the sole 1 of the shoe S This embodiment allows the wearer to effortlessly control his or her body movement by engaging the ground contact on each section of the sole of the foot F detects the applied load.

Furthermore, each of the lower elevations 11 formed as a columnar, for example, as described above substantially in the form of a quadrangular prism, and bottom surfaces thereof serve as first regions R1 , In this embodiment, the first areas R1 formed as relatively wide, flat surfaces, allowing easy transfer of reaction force from the ground G on the first areas R1 allows. Thereby, the reaction force generated upon contact with the ground can be appropriately determined from the first areas R1 to the second areas R2 be transmitted.

Furthermore, the upper elevations include 13 the second areas R2 , which depend on their position in relation to the sections of the sole F of the carrier are different sizes. Thereby, the reaction force generated upon contact with the ground can be adequately applied to the portions of the sole of the foot F be transmitted. In particular, excessive pressure may be due to a pain-sensitive portion of the sole of the foot F exercised, be regulated.

In addition, the upper elevations 13 depending on their positions in relation to the sections of the sole of the foot F different heights of the carrier. Therefore, the reaction force generated upon contact with the ground can be adequately applied to the portions of the sole of the foot F be transmitted. In particular, excessive pressure may be due to a pain-sensitive portion of the sole of the foot F exercised, be regulated.

Furthermore, a bending of the upper elevations 13 in that area X regardless of the size of the lower elevations 11 transferred reaction force can be avoided, since the upper elevations 13 in that area X are shorter than the upper elevations 13 in that area Y ,
