Description

The sneakers which improved the comfort of the upper

technical field

The present invention relates to sports shoes with improved comfort of the upper.

Background technique

In general, uppers are designed with the shape of the foot in mind when at rest. The shape of the foot during exercise often changes inside the shoe. That is, during exercise, the upper sometimes cannot keep up with the deformation of the foot and separates the sole from the foot, or sometimes the upper restricts the natural deformation of the foot. Therefore, the shoe upper is considered as a part that makes the sole follow the foot, and at this time, it is desirable that the shoe upper deforms following changes in the shape of the foot during exercise.

That is, since the feet are deformed during walking, shoes are required to have good comfort for the feet. In order to improve the above-mentioned comfort, the deformation distribution of the upper is preferably close to the deformation distribution of the foot.

As shoes with improved comfort, Patent Document 1 (Japanese Patent Publication No. 4-107608 (Fig. 1)), Patent Document 2 (Japanese Patent Publication No. Showa 60-18082 (Fig. 1)) are known. ), Patent Document 3 (Japanese Patent Laid-Open No. 2000-287704 (Fig. 2)), Patent Document 4 (Japanese Patent Utility Laid-Open No. 1-26245 (Fig. 1)) and Patent Document 5 (Japanese Patent Laid-Open No. 2000 - Shoes from Bulletin No. 184902 (Abstract)).

FIG. 16(b) shows the shoe in the above-mentioned Patent Document 2. In this shoe, a part of both sides of the boot opening 101 of the shoe upper U is formed by the elastic member 100 .

What Fig. 16(c) and Fig. 16(d) show is the shoe in the above-mentioned Patent Document 3. In this shoe, both sides of the front portion of the upper U are formed by elastic members 100 .

FIG. 17( a ) shows the shoe in Patent Document 4 mentioned above. In this shoe, the front part of the opening of the shoe upper U is formed by the flexible member 100 .

What FIG. 17(b) shows is the shoe in the said patent document 5. As shown in FIG. In this shoe, a chock-shaped cutout portion 102 of an upper U is formed by a stretchable member 100 . The cutout portion 102 shortens from the opening 103 of the upper U toward the sole.

Contents of the invention

However, as described below, these shoes are not designed to follow the deformation of the foot while walking.

What Fig. 2 (a) and Fig. 2 (b) have shown is the perspective view of foot.

Generally, when walking, it is necessary to raise the heel of the foot in order to push off the ground. At this time, with the vicinity 81 of the arch of the foot and the vicinity 80 of the little toe on the outside of the foot in FIGS. This difference in motion is not noticeable when the foot is at rest.

The vicinity 81 of the arch portion of the inner side of the foot includes a portion covering the tarsal metatarsal joint of the foot and a portion in the vicinity thereof. The vicinity 80 of the little toe on the outer side of the foot includes a portion covering the fifth metatarsal bone of the foot and a portion in the vicinity thereof. Between the front and back of these parts, the deformation distribution of the foot during walking changes rapidly. Between the front portion and the rear portion of the aforementioned portion of the foot, the distribution of deformation during walking is discontinuous.

Here, in the shoes of each of the above patent documents, the stretchable member does not cover both the inner arch portion and the little toe. Therefore, when walking, the deformation of the shoe does not follow the deformation of the foot, and the wearer of the shoe feels stiff between the foot and the shoe, and the shoe does not follow (fit) the foot properly. As a result, bending or movement of the foot is hindered during exercise.

In the shoe of Patent Document 2 mentioned above, the elastic members 100 are arranged on both sides of the boot opening of the shoe so as to face each other. As a result, the upper U tends to bend unnecessarily, so the shoe tends to lose shape and lack stability.

The object of the present invention is to solve the above-mentioned problem of improving the fit of shoes by an improved shoe upper with improved comfort.

In order to achieve the above object, in a first embodiment of the present invention, a sports shoe suitable for sports is provided. The shoe has a sole that absorbs the impact of landing and an upper that wraps around the instep.

The vamp includes a first opening from above through which the foot protrudes when worn, and a second opening above the instep that is sealed by the tongue. The two openings are connected to each other front and back. The shoe upper includes: an inner elastic part covering a part of the inner surface of the foot, an outer elastic part covering a part of the outer surface of the foot, a front part and a It is attached to each of the two telescopic parts, and is arranged at the rear part behind it. The elastic modulus of elasticity in the leg length direction of each of the stretchable parts is smaller than the modulus of elasticity in tension of the front and rear parts.

The outer telescopic part is provided in a region from the skull corresponding to the distal end of the fifth metatarsal or its vicinity to the second opening. That is, it extends from a site substantially corresponding to the upper end of the distal skull of the fifth metatarsal bone to the second opening. The area includes an obliquely upward line extending from the vicinity to the front of the vicinity. That is, the region includes a line that slopes upward as it extends forward. The outer stretchable portion has a stretchable length in the vicinity along the foot length direction.

In this way, since the outer telescopic portion is provided at or near the upper end of the skull substantially corresponding to the fifth metatarsal bone, the portion where the deformation distribution of the foot can be rapidly increased is covered by an elastic member. . As a result, the upper can deform as said region deforms, resulting in an improved fit.

In the present invention, the use of the term "a site substantially corresponding to the upper end of the distal skull of the fifth metatarsal" means not only the site corresponding exactly to the upper end of the fifth metatarsal, but also the vicinity thereof. Therefore, even in the case where the lateral telescopic portion extends from a little above the site to the second opening, the lateral telescopic portion is provided at a distance from “a portion substantially corresponding to the upper end of the distal skull of the fifth metatarsal bone” to the second opening. area.

Furthermore, the outer stretchable portion has a sufficient length to be stretchable in the foot length direction at the above-mentioned portion. Accordingly, the front front leg portion and the rear rear leg portion of the outer elastic portion do not interfere with each other, and function substantially independently. That is, the movement of the front leg and the movement of the rear leg are separated from each other by the outer stretchable portion. According to this, the vamp can deform more freely without restricting the natural deformation of the foot during movement, so the fit is further improved. This action will be described in detail in the embodiments described later.

According to another embodiment of the present invention, there is provided an athletic shoe adapted for sports having a sole that absorbs landing shock and an upper that encloses an instep. The upper has a first opening through which the foot protrudes above when worn and a second opening closed by the tongue. The two openings are connected to each other. The vamp includes: covering at least a part of the inner surface of the arch of the foot, that is, a part or all of the inner elastic part, covering at least a part of the outer surface of the little toe of the foot, that is, a part or all of the outer elastic part, arranged on the A front part in front of the two telescopic parts and a rear part disposed behind the two telescopic parts. The telescoping parts are arranged in such a way that a side surface of the shoe upper is substantially traversed from the upper surface of the sole to the second opening. The elastic modulus of tension in the leg length direction of each of the stretchable parts is smaller than that of the front and rear parts.

When exercising, if the heel is raised and the arch of the foot and the vicinity of the little toe are deformed, the inner elastic portion and the outer elastic portion of the shoe upper expand and contract with the deformation of the foot. As a result, the sole does not detach from the foot and the upper does not restrict the natural deformation of the foot in action. That is, comfort is high.

Each telescopic portion substantially traverses the side surface of the upper from the upper surface of the sole to the second opening. Therefore, when the shoe is worn with the laces tightly or the heel is not raised, the stretchable parts contract, and the front part and the rear part fit the front part of the foot and the rear part of the foot, respectively.

In addition, in the present invention, the inner elastic part covers at least a part of the inner surface of the arch of the foot, and the outer elastic part covers at least a part of the outer surface of the little toe.

According to this method, when exercising, the inner and outer elastic parts of the upper extend across the inner and outer sides of the upper respectively, covering at least a part of the arch of the foot and the side of the little toe. Therefore, Improved comfort.

In the present invention, by using the phrase "a side surface of the shoe upper that is substantially transverse from the upper surface of the shoe sole to the second opening", it means that the upper surface of the shoe upper is provided on the side surface of the shoe upper by a stretchable member. To the second opening, about a portion along the edge portion of the second opening, expansion and contraction are allowed. For example, if an eyelet modification is provided along the edge of the second opening, and when the eyelet modification is cut out, when the cutout is covered only from the outer side, the stretchable member Also "substantially transverse" the sides of the upper.

In another aspect, according to another embodiment of the present invention, there is provided an athletic shoe adapted for sports having a sole that absorbs landing impact and an upper that encloses an instep. The upper is defined as a first opening through which the foot protrudes above and a second opening closed by a tongue when worn. The two openings are connected to each other. The vamp includes: covering at least a part of the inner surface of the arch of the foot, that is, a part or all of the inner elastic part, covering at least a part of the outer surface of the little toe of the foot, that is, a part or all of the outer elastic part, arranged on the A front part in front of the two telescopic parts and a rear part disposed behind the two telescopic parts. The telescoping parts are arranged in such a way that a side surface of the shoe upper is substantially traversed from the upper surface of the sole to the second opening. The tensile elastic modulus of each stretchable portion in the foot length direction is smaller than the tensile elastic modulus of the related front portion and rear portion. A front reinforcing material is provided on a rear edge of the front part, and a rear reinforcing material is provided on a front edge of the rear part. A tensile modulus of elasticity of a portion on the outside of the foot corresponding to the position of the inner elastic portion is greater than that of the inner elastic portion. Similarly, the elastic modulus of elasticity of the portion of the inner side of the foot corresponding to the position of the outer elastic portion is larger than that of the outer elastic portion. That is, since the two telescopic portions do not face each other, the outer side of the vamp opposite or facing to the inner telescopic portion has a larger tensile modulus of elasticity than the inner telescopic portion. Likewise, the inner surface of the shoe upper facing or opposite to the above-mentioned outer stretchable portion has a larger tensile modulus of elasticity than that of the outer stretchable portion.

The front and rear parts are separated from each other in the front-back direction of the foot. When the shoe is worn on the foot, the elastic part expands and contracts with the movement of the foot, and the front and rear parts of the upper fit the shoe. At this time, even if the telescopic part stretches, the rear edge of the front part and the front edge of the rear part are reinforced with reinforcing materials, so the front part and the rear part will not go out of shape, and the front part of the vamp is suitable for the toes. The rear fits the heel.

In addition, the tensile modulus of the side surface opposite to each stretchable portion is larger than the stretchable modulus of the stretchable portion. That is, the side surface on the opposite side to each stretchable portion has a higher tensile modulus than the stretchable portion. In this way, the upper supports the sides of the foot, thus, providing stability to the foot. On the other hand, in the case where the shoe upper has two opposing inner and outer sides made of soft or elastic members, neither side of the foot is supported, and thus the stability of the foot becomes low.

According to this mode, even if the telescoping part is stretched, the rear edge of the front part and the front edge of the rear part are reinforced with reinforcing materials, so that the front part and the rear part do not go out of shape, and the front part of the upper fits the toes, The rear fits the heel. Moreover, the tensile elastic modulus of the side opposite to the stretchable portion is greater than that of the corresponding stretchable portion, so that the stabilizing function of the foot provided by the upper is not impaired.

In a preferred embodiment of the present invention, the edge portion near the second opening of each stretchable portion is formed of a material that allows the stretchable portion to expand and contract. On the other hand, the front portion and the rear portion each have a peripheral portion connected to the second opening, and the peripheral portion is substantially formed of an inelastic or substantially hard-to-stretch material.

Here, the edge portion of the stretchable portion is easy to stretch. Therefore, the resistance when the foot is bent becomes small, and the bending motion of the foot can be performed smoothly. On the other hand, the peripheral parts of the front part and the rear part are formed of a material that is substantially difficult to expand and contract. Therefore, when the shoe is fastened by the shoelace, the shape of the shoe is difficult to lose shape, so the fit is not lowered.

In the present invention, by using the term "substantially inelastic material" or "substantially non-elastic (inelastic) material", it is meant to include the material generally used in sports shoes and the tensile elasticity of the stretchable part. Raw material with high modulus.

In another preferred embodiment of the present invention, each of the stretchable parts has a substantially triangular or trapezoidal shape in which the width along the front-back direction of the foot becomes smaller as the shoe sole approaches the second opening.

In this way, the shape of each stretchable portion is triangular or even a platform shape, so that the deformation of the shoe upper in the foot length direction is allowed to match the deformation of the foot.

In another embodiment of the present invention, each of the stretchable parts includes a plurality of overlapping blanks. With this configuration, the blank can be deformed independently of each other in the central regions of the telescopic portions. That is, the plurality of blanks can be deformed independently of each other to be stacked in the central region.

According to this embodiment, among the plurality of blanks, the inner blank of the connecting leg is deformed along with the deformation of the leg, and among the plurality of blanks, the outer blank and the inner blank are deformed independently. As a result, the difference in deformation between the shoe upper and the foot can be absorbed. That is, it is possible to accommodate deformation differences between the upper and the foot.

In addition, the use of the term "material" here means a sheet-like material used for an upper of shoes. Rubber or resin sheets, woven, braided and/or non-woven fabrics may be included.

In the present invention, the edge portion of the second opening along the upper is preferably cut at positions corresponding to the stretchable portions. That is, the edge portion of the shoe upper is provided with a notch at a position corresponding to the stretchable portion, or the edge portion is cut to form an inner notch and an outer notch. By cutting the edge portion on the inner side or the outer side of the foot, the portion near the second opening is easily bent, and the flexibility of the shoe is remarkably improved.

In this case, it is preferable to integrally form an elastic member made of an elastic body along an upper edge portion of the cutout portion. As a result, stretchability and durability are improved by the elastic member.

The cutout portion may be cut into any shape such as a V shape. It is preferable that the notch is formed in a U-shape. As a result, concentration of stress can be alleviated, thereby improving durability.

Next, materials for forming the front portion 3, the rear portion 4, and the stretchable portions 50, 51 will be described.

The front part 3 and the rear part 4 are produced by laminating (preferably interconnecting) blanks such as textiles or braids used for ordinary sports shoes. On the front part 3 and the rear part 4, a belt-shaped member for fixing the core material is sewn on the upper surface of the above-mentioned raw material as needed.

Each of the stretchable portions 50, 51 includes a base material 55 formed by stacking (stacking or laminating) a plurality of stretchable blanks 57, 58 as shown in the sectional view of FIG. 7(a). The blanks 57, 58 are sewn at the aforementioned rear edge 33 of the front and at the front edge 43 of the rear. Since the blanks 57, 58 are neither connected nor sewn at the central portions of the telescopic parts 50, 51, they can freely slide on the blanks and deform independently of each other.

As shown in the cross-sectional view of FIG. 7( b ), an elastic member 56 is partially provided on the blank 57 on the above-mentioned base material 55 .

In addition, the elastic member 56 is laminated in the inner elastic portion 51 from the notch portion 63 to the upper surface of the sole S so as to cross the inner elastic portion 51 . In this way, the expansion and contraction in the vertical direction of the inner side expansion and contraction part 51 can be suppressed smaller than the expansion and contraction in the foot length direction.

As shown in FIG. 4 , the elastic member 56 is also laminated on the outer elastic portion 50 in the same manner.

On the other hand, as shown in the sectional view of Fig. 7(c), in the part of the above-mentioned reinforcement materials 6, 7, the above-mentioned elastic parts 50, 51 are sewn on the belt-shaped members of the above-mentioned reinforcement materials 6, 7 (Fig. 5). The blanks 57, 58 of the front part 3 or the blanks 37, 38 of the rear part 4.

When the feet are put on the shoes, the shoelace R shown in FIG. 6 is loosened, and the feet are inserted into the shoes from the rear of the first opening 1 and the second opening 2 . At this time, the inner and outer telescopic parts 51, 50 are slightly stretched in the foot length direction, the front part 3 fits the fingertips of the feet, and the rear part 4 fits the heels.

As shown in Figure 2 (a), when walking, the heel is lifted upwards to make the foot bend. At this time, with the vicinity 80 of the little toe and the vicinity 81 of the arch of the inner side of the foot as the boundary, the movements of the front foot and the rear foot There are big differences. At this time, the vamp U stretches near the upper surface of the sole S in FIG. 3 , and the vamp U shrinks near the second opening 2 . Therefore, for the stretchable parts 51 and 50 of the sports shoes, the part near the sole S is stretched in the foot length direction L, and the tensile modulus of elasticity in the foot length direction L of this part is small. Therefore, the stretchable parts 51, 50 are easy to stretch near the portion of the sole S. On the other hand, since the notches 63 , 64 are provided near the second opening 2 of the expandable parts 51 , 50 , the expandable parts 51 , 50 are easily contracted near the second opening 2 . Therefore, the upper U is made to fit the foot.

As shown in FIG. 2 , as for the outer portion 82 near the lower part of the heel, when the foot is bent, there is a large difference in the movement of the front and rear of the foot with it as a boundary. Therefore, it is preferable to arrange the expansion and contraction member at the outer portion 82 near the bottom of the above-mentioned heel in addition to the parts 80 and 81 near the little toe and the arch of the foot.

(second embodiment)

8 and 9 show a second embodiment of the shoe of the present invention. Fig. 8 shows the inner side of the shoe (left foot), and Fig. 9 shows the outer side thereof. In addition, in FIG. 8 and FIG. 9 , in order to facilitate understanding of the installation location of the telescopic part, grids are drawn on the telescopic part. In addition, in the following embodiments, the same reference numerals are given to the same parts as those of the first embodiment or corresponding parts, and detailed descriptions and illustrations thereof will be omitted.

As shown in FIG. 8 , in the present embodiment, the above-mentioned elastic member 56 of the inner expandable portion 51 is divided in the vertical direction.

In addition, as shown in FIG. 8 , the first inner portion 61 is formed in a bifurcated shape. Furthermore, as shown in FIG. 9 , the outer eyelet modification portion 72C extends to the upper surface of the sole S at the rear of the foot.

(third embodiment)

Figure 10 shows a third embodiment of the shoe of the present invention. Fig. 10(a) is a perspective view of the inner telescopic part and its vicinity in this embodiment, and Fig. 10(b) is an exploded perspective view of this part.

In this embodiment, as shown in FIG. 10( a ), the ring P covers the above-mentioned inner cutout portion 63 . As shown by the dotted line, both ends of the ring P are sewn to the upper ends of the first inner portion 71 and the second inner portion 61 , but are not sewn to the eyelet modification portions 62 , 72B. Therefore, the ring P allows the expansion and contraction operation of the above-mentioned inner expansion and contraction portion 51 .

Moreover, as shown in the exploded perspective view of FIG.10(b), each part 61,62 of the front part reinforcement material 6, and each part 71,72B of the rear part reinforcement material 7 form a mutually different entity. The upper ends of the respective inner portions 61 , 71 of the reinforcing materials 6 , 7 are respectively close to the eyelet finishing portions 62 , 72B. In this way, since there is no need to integrally form the reinforcing materials 6, 7, the cost can be reduced.

As shown by the dotted line in Fig. 10(a), the first inner part 61 and the second inner part 71, together with the blanks 57, 58 of the inner telescopic part 51, are sewn on the rear edge of the front part 3 and the front edge of the rear part respectively. .

(fourth embodiment)

Fig. 11 shows the fourth embodiment. Fig. 11(a) is a perspective view of the inner telescopic part of this embodiment and its vicinity, and Fig. 11(b) is an exploded perspective view of this part.

In this embodiment, as shown in FIG. 11( b ), the ring P is integrally formed with the first inner portion 61 and the second inner portion 71 . As shown in FIG. 11( a ), the ring P is not sewn to the eyelet modification parts 62 , 72B. Therefore, like the above-mentioned third embodiment, the ring P allows the telescopic movement of the above-mentioned inner telescoping portion 51 .

(fifth embodiment)

What Fig. 12 and Fig. 13 have shown is the shoe that the court game (for example volleyball) of the fifth embodiment is used. What Fig. 12 (a) has shown is the inner side of the shoe (right foot) of this embodiment, and Fig. 12 (b) has shown its outer side. Fig. 12(c) shows the relationship between the above-mentioned lateral surface and the foot bones. 13( a ), ( b ) are enlarged side views of the vicinity of the outer telescopic part 50 .

In FIG. 12( a ), FIG. 12( b ), FIG. 13( b ), FIG. 14( a ) and FIG. 14( b ), in order to facilitate understanding of where the telescopic parts are installed, grids are drawn on the telescopic parts.

As shown in Fig. 12(a), the inner side telescopic part 51 of the shoe of the present embodiment is arranged like this: from the upper surface of the sole S to the second opening 2, it is substantially transverse to the inner side 31 of the vamp U. This configuration is the same as that of the first embodiment described above. The inner telescopic part 51 is substantially rectangular or square-shaped. The eyelet finishing part 62 on the front side is provided separately inside and outside the second opening 2 , and is not arranged inside and outside the second opening 2 .

As shown in FIG. 12( b ), on the outer surface 30 of the shoe upper U, below the outer stretchable portion 50 , a connecting portion 69 connecting the rear portion 4 from the front portion 3 is provided. In appearance, the outer telescopic portion 50 does not extend to the upper surface of the sole. The outer stretchable part 50 is provided downward from the second opening 2 to about half or more of the height of the upper U. The connecting portion 69 is made of the same or similar material as the second inner portion 70 . The tensile modulus of elasticity in the leg length direction L of the connecting portion 69 is set to be larger than the tensile modulus of the outer stretchable portion 50 . Below the above-mentioned connecting portion 69, there is formed a roll upper portion 68 protruding so that the sole S rolls upward.

Next, the structure in the vicinity of the outer telescopic part 50 described above will be described.

As shown in Fig. 13(a) and Fig. 13(b), in the position surrounded by the first inner side part 60, the second inner side part 70 and the sole S (the position indicated by the dotted line), a stretchable shoe is arranged. Part 54. Then, the connecting portion 69 is sewn to cover the lower surface of the stretchable member 54 arranged in this way. The connecting portion 69 is substantially made of a material that is difficult to expand and contract, so the lower portion of the elastic member 54 hardly expands and contracts. On the other hand, the rectangle or square part surrounded by the first outer part 60 of Fig. 13 (b), the second inner part 70, the connecting part 69 and the edge part 35 of the second opening 2 can be stretched and contracted, and this part is The outer telescopic part 50.

The relationship with each part of the femoral bones of the outer telescopic part 50 described above will be described below.

As shown in FIG. 12( b ) and FIG. 12( c ), the connecting portion 69 and the rolled up portion 68 are located at a position corresponding to the distal end head 90 of the fifth metatarsal bone on the outer side of the foot. The connecting portion 69 and the upper roll portion 68 are substantially made of a material that is difficult to expand and contract. Therefore, in shoes for court games in which movements in the foot width direction are intense, the outer side of the above-mentioned part is supported by the above-mentioned connecting portion 69 and the roll-up portion 68 . On the other hand, the outer telescopic part 50 is arranged in a region extending from the above-mentioned location to the second opening 2 . The above-mentioned area includes a straight line D extending obliquely upward from the above-mentioned portion toward the second opening 2 . Therefore, the front part 3 and the rear part 4 of the shoe upper U can move independently of each other with the position along the middle toe joint (MP joint) 93 as a boundary. That is, the front part 3 and the rear part 4 of the shoe upper U move differently with the region corresponding to the MP joint as a boundary.

Wherein, in this embodiment, the connecting portion 69 and the second outer portion 70 are integrally formed, but they may also be formed as separate bodies, or the connecting portion 69 and the first outer portion 60 may be integrally formed. In addition, the connecting portion 69 may not be provided, and only the roll-up portion 68 of the sole S may support the portion corresponding to the above-mentioned fifth metatarsal distal end 90 .

(sixth embodiment)

Fig. 14 shows a sixth embodiment of the travel shoe. Fig. 14 (a) is the inner surface of the shoe (left foot) of the present embodiment, and Fig. 14 (b) is its outer surface, and Fig. 14 (c) shows the relationship between the above-mentioned outer surface and the foot bone.

As shown in FIG. 14( a ), the inner telescopic portion 51 of this embodiment is provided downward from the second opening 2 to about half of the height of the upper U. The inner and outer telescopic parts 51 and 50 are arranged on opposite sides of the second opening 2 . That is, the inner telescopic part 51 faces the outer telescopic part 50 through the second opening 2 . Between the inner elastic portion 51 and the sole S, a member substantially made of a material that is difficult to expand and contract is disposed.

In addition, a belt-shaped protective member 55 made of a material that is substantially difficult to expand and contract is sewn to the front and rear centers of the inner expandable portion 51 . The inner telescopic part 51 is divided into front and back two parts by this protection member 55. As shown in FIG. Such a protection member 55 protects the inner telescopic part 51 which is weak against impact from the outside.

On the other hand, as shown in FIG. 14( c ), the outer telescopic portion 50 is arranged in the same area as the above-mentioned first embodiment (the area extending from the position corresponding to the fifth metatarsal distal head 90 to the second opening). In addition, the outer telescopic part 50 is divided into front and back two parts by the protection member 55 similarly to the said inner telescopic part 51. As shown in FIG. As shown in FIG. 14( b ), the front portion of the divided outer elastic portion 50 crosses the outer surface 30 of the shoe upper from the upper surface of the sole S to the second opening.

The bending direction of the foot when climbing a mountain is different from that when running. Therefore, the shoe must have a different construction. By sewing the above-mentioned protective member 55 or its non-stretchable parts at appropriate positions in each stretchable portion 50, 51, the stretchable direction of each stretchable portion 50, 51 can be adjusted, so that each stretchable portion 50, 51 is suitable for the above-mentioned feet. of the bend.

In order to protect the position corresponding to the scaphoid bone of the foot and its vicinity, this position is located at the rear portion 4 of the vamp U, and may not be covered from the inside.

The function of the outer telescopic part:

In the above-mentioned six embodiments, the outer telescopic portion 50 is approximately formed in a substantially rectangular shape, a substantially square shape, or a substantially triangular trapezoidal shape, and at the same time, as shown in FIG. The portion of the metatarsal bone distal end 90 or its vicinity is set to have a length in the foot length direction. Next, the operation of such a setting will be described using conceptual diagrams ( FIGS. 15( a ) to 15 ( e )) of the outer telescopic portion. In addition, in FIGS. 15( a ) to 15 ( e ), grids are drawn for the expansion and contraction parts in order to facilitate understanding of the installation locations of the expansion and contraction parts.

In the conventional example ( FIG. 15( e )), an inverted triangular small elastic portion 500 is provided on the outer side of the foot. Here, when a force in the leg length direction L is applied to the stretchable portion 500, the stretchable portion 500 expands as shown by the dotted line M with two dots in the figure. At this time, the expansion and contraction rate at the bottom point 501 of the expansion and contraction part 500 is zero. That is, since the lower portion of the inverted triangular elastic portion 500 does not have a certain length in the leg length direction L, the lower portion hardly expands and contracts. In this way, most of the lateral surface of the shoe upper is hardly stretched in the foot length direction L.

According to the present invention, as shown in FIG. 15( a ), the outer telescopic portion 50 is formed in a substantially square shape or a substantially rectangular shape. Between the outer stretchable portion 50 and the sole S, a connecting portion 69 that is difficult to expand and contract is provided. In such a structure, when a force in the leg length direction L is applied to the outer elastic portion 50 , the outer elastic portion 50 expands as indicated by the two-dot dashed line M1 in the figure. Here, at a site (point) O corresponding to the vicinity of the fifth metatarsal distal head 90, since the outer elastic portion 50 has a certain length in the foot length direction L, this portion can expand and contract in the foot length direction L. That is, in the range from the above-mentioned portion O to the second opening 2, the outer elastic portion 50 can expand and contract in the front and rear.

On the other hand, in FIG. 15( b ), the outer telescopic portion 50 is substantially formed in a substantially triangular trapezoidal shape, and is provided on the upper surface of the sole S from the second opening 2 . In this configuration, the length of the outer telescoping portion 50 near the second opening 2 is very short. However, the outer expandable portion 50 has a V-shaped or U-shaped notch portion 58 in the vicinity of the second opening 2 . Therefore, even in this configuration, the outer elastic portion 50 can expand and contract in the foot length direction L in the vicinity of the second opening 2 .

In this way, in the case of the above-mentioned substantially trapezoidal shape, substantially rectangular shape, or substantially square shape, the outer telescopic portion 50 can be deformed into various shapes in response to an external force. Therefore, during exercise, the outer telescopic part 50 expands and contracts along with the deformation of the foot, and the front part 3 and the rear part 4 can move independently of each other with the region near the fifth metatarsal bone distal head 90 as a boundary. As a result, the upper can follow the different movements of the forefoot and rearfoot.

Therefore, in the range from the position O in the vicinity of the fifth metatarsal distal end head 90 to the second opening 2, if the outer telescopic portion 50 has a telescopic arrangement that can stretch along the foot length direction L, then the outer telescopic portion 50 is defined as boundaries, the upper can easily and adequately follow the widely differing forefoot and rearfoot movements.

The telescopic installation of the region including the above-mentioned portion O can be achieved by having the outer telescopic portion 50 have a certain length in this region.

Like running shoes, when a high degree of stretchability is required, the outer stretchable portion 50 is provided to traverse the outer surface of the upper U from the second opening 2 to the upper surface of the sole S. As in shoes for court games or sneakers, when proper elasticity and sufficient supporting force are required, a connecting portion 69 may be provided between the outer elastic portion 50 and the sole S, or it may be placed on the upper surface of the sole S. On the surface, the outer telescopic part 50 does not have a length that can be stretched.

On the other hand, the telescopic installation near the second opening 2 can be realized by having the outer telescopic portion 50 have a certain length along the second opening 2 . Even the very short substantially triangular outer telescopic portion 50 of the above-mentioned length can be stretched if the outer telescopic portion 50 has a U-shaped or V-shaped notch 58 near the second opening 2 .

As the outer telescopic part 50 having a substantially square shape or a substantially rectangular shape, as shown in FIG. As shown in FIG. 15( d ), the outer elastic portion 50 may be formed in a tapered shape at the upper and lower centers of the outer elastic portion 50 .

In addition, in order to obtain sufficient expansion and contraction while preventing unnecessary expansion and contraction, the elastic constant k per unit height W (FIG. 15(a)) of the outer elastic portion 50 is preferably set to 0.1N/mm to 50N/mm. about mm. Here, the above-mentioned elastic constant is a numerical value defined by cutting a slender test piece from the elastic portion in the foot length direction and loading the test piece with a load f along the foot length direction. The deformation ε generated on the test piece and the width W of the test piece are divided by the above-mentioned load f. The elastic constant k is represented by the following formula (1):

k=f/(ε·W)...(1).

Thus, the reason for introducing the concept of "elastic constant" in the present invention is that the thickness of the material of the shoe upper is not clear. That is, the exact thickness of the raw material of the shoe upper is difficult to measure. Therefore, it is difficult to obtain an accurate numerical value of the tensile modulus of elasticity described below of the raw material of the shoe upper. The above "elastic constant" k can be obtained without measuring the exact thickness of the raw material of the shoe upper.

The tensile elastic modulus is a numerical value defined by dividing the deformation ε of the test piece and the cross-sectional area S of the test piece by the load f above. That is, the tensile modulus E is represented by the following formula (2):

E=f/(ε·S)...(2).

The ideal value of the above-mentioned elastic constant k differs depending on the use, size or type of the shoe, and the shape or size of the elastic portion. The elastic constant k described above is preferably set to about 0.1 N/mm to 7.0 N/mm in the shoes shown in FIGS. 1 to 11( b ) and FIGS. 14( a ) to 14( c ). In addition, the above-mentioned elastic constant k is preferably set to about 0.1 N/mm to 3.0 N/mm in the running shoes of FIGS. 1 to 11( b ), for example. In the sports shoes of Fig. 12(a) to Fig. 13(b), it is preferable to set it to about 10N/mm to 30N/mm. In the sneakers of FIGS. 14( a ) to 14 ( c ), it is preferable to set it to about 1.0 N/mm to 7.0 N/mm.

These specific numerical values of the elastic constant k are expected to be set to larger numerical values than the elastic constant k of conventional elastic materials. In the present invention, the stretchable portion 50 needs to have a certain length in the foot length direction L. As shown in FIG. Therefore, if the stretchable portion 50 is made to expand and contract too easily, the function of holding the feet will be too low. Therefore, the spring constant k of the material of the stretchable portion 50 is set to be large so that the stretchable portion 50 is formed to be long in the leg length direction L.

Above, only a few typical embodiments of the present invention have been described in detail. If a person skilled in the art, in the above-mentioned typical embodiments, it will be easy to recognize that as long as it does not depart from the new connotation of the present invention And advantages, can carry out many deformations. Therefore, all similar modifications are considered to be included in the scope of the present invention.

industrial availability

In addition to running shoes and walking shoes, the present invention can also be used for court game shoes such as volleyball, basketball, tennis, etc., hiking shoes, etc., or various sports shoes such as golf shoes and soccer shoes. For example, when the present invention is applied to golf shoes made of a hard resin sole, the comfort can be improved by providing bending grooves in the sole corresponding to the positions where the expansion and contraction members are provided.
