Patent document 1: japanese patent No. 6068775
Disclosure of Invention
Problems to be solved by the invention
Various functions are required for the upper of footwear as described in japanese patent No. 6068775. For example, there are the following cases: a toe region located at a front end portion of the upper in the longitudinal direction of the footwear or a heel region located at a rear end portion of the upper in the longitudinal direction is required to have high rigidity (strength), and an intermediate region located at an intermediate portion of the upper in the longitudinal direction of the footwear is required to have air permeability. In this case, it is considered that the upper is formed of a cloth having high air permeability, and another cloth having relatively high rigidity is attached to the toe region and the heel region thereof by bonding, sewing, or the like.
However, in the case where another cloth is attached to the cloth having air permeability, the adhesive causes an increase in weight of the upper or a partial stiffening of the upper. In addition, in the case of sewing other cloth to the cloth having air permeability, the ordered upper requires a sewing margin, and thus the weight of the upper increases.
The purpose of the present disclosure is to provide footwear that can ensure ventilation in the middle region and rigidity in the toe region and heel region without adhesion or sewing.
Means for solving the problems
The footwear of an aspect of the present disclosure is a footwear including a sole and an upper, the upper having a single cloth portion including a base layer having air permeability, the single cloth portion having: a strength section having the base layer, a ventilation layer having air permeability, and a strength layer comprising a single or multiple fibers and connecting the base layer and the ventilation layer; and a ventilation section having only the base layer or only two layers of the base layer and the ventilation layer, wherein the base layer has a shape extending from a toe region located at a front end portion of the footwear in a longitudinal direction to a heel region located at a rear end portion of the footwear in the longitudinal direction, and the strength section includes: a toe strength section disposed in the toe region; and a heel strength section disposed in the heel region, the ventilation section including an intermediate ventilation section disposed in an intermediate region between the toe region and the heel region.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present disclosure, it is possible to provide footwear that can ensure ventilation in the middle region and rigidity in the toe region and the heel region without performing adhesion or sewing.

Detailed Description
Embodiments of the present disclosure will be described with reference to the accompanying drawings. In the drawings referred to below, the same or corresponding members are denoted by the same reference numerals. In the following description, terms such as longitudinal direction, width direction, front, rear, and the like are used. These directional terms represent directions as viewed from the point of view of a wearer wearing footwear 1 placed on a ground or the like plane. For example, the front refers to the toe side and the rear refers to the heel side. Further, the inner side (first toe side) of the foot in the inner foot side finger width direction, and the outer side of the foot in the outer foot side finger width direction.

Fig. 1 is a plan view schematically showing footwear according to a first embodiment of the present disclosure. Fig. 2 is a left side view of the footwear shown in fig. 1. Fig. 3 is a right side view of the footwear shown in fig. 1. Although the footwear 1 for the left foot is shown in fig. 1 to 3, the footwear 1 may be applied to the right foot, and in this case, is symmetrical to the footwear 1 for the left foot. The footwear 1 of the present embodiment can be used as, for example, sports shoes or walking shoes, and is not limited to the use of footwear.
As shown in fig. 1 to 3, the footwear 1 includes a sole 5 and an upper 10.
The upper 10 is connected to the sole 5, and forms a space for receiving a foot together with the sole 5. The upper 10 has an inner foot covering portion 11, an outer foot covering portion 12, a pin portion 10h1, and a throat portion 10h2.
The inner sole covering portion 11 is a portion that covers at least a part of the inner sole surface of the foot. The inner foot covering portion 11 includes a portion of the upper 10 on the inner side (right side in fig. 1) of the center line a passing through the center in the width direction of the footwear 1. The centerline a may be a line connecting the calcaneus center of the foot of the standard wearer of the footwear 1 and a position corresponding to a line passing between the first toe and the second toe of the foot, instead of being the centerline of the footwear 1 in the width direction. The medial and lateral sides are defined with respect to the center line of the footwear 1 in the width direction, but this is not critical.
The outer leg covering portion 12 covers at least a part of the outer leg surface of the leg. The outer foot covering portion 12 includes a portion on the outer side (left side in fig. 1) of the center line a in the upper 10.
The pin portion 10h1 is provided between the inner foot covering portion 11 and the outer foot covering portion 12 in the width direction of the footwear 1, and is a portion that allows the foot to enter and exit.
The throat portion 10h2 is an opening having a shape extending from the pin portion 10h1 to the front in the longitudinal direction of the footwear 1. The throat portion 10h2 is provided in the intermediate region R3. The intermediate region R3 is a region located between a toe region R1 located at the front end portion in the longitudinal direction of the footwear 1 and a heel region R2 located at the rear end portion in the longitudinal direction of the footwear 1.
The toe region R1 is a region located in a range of approximately 0% to 4% from the front end portion toward the rear end portion of the footwear 1 with respect to the entire length of the footwear 1. The intermediate region R3 is a region located in a range of about 4% to 80% from the front end portion toward the rear end portion of the footwear 1 with respect to the entire length of the footwear 1.

The base layer 101 includes, for example, a mesh-like cloth. The single fabric portion 100 includes a knit.
The single cloth part 100 has a strength part 110 and a ventilation part 120. In each of the drawings, a dot pattern is given to the strength portion 110, and a mesh pattern is given to the ventilation portion 120.
The ventilation layer 102 is a layer having ventilation properties. The ventilation layer 102 includes, for example, a mesh-like cloth. The ventilation layer 102 may comprise the same cloth as the base layer 101.
The strength layer 103 is disposed between the base layer 101 and the ventilation layer 102. The strength layer 103 comprises a single or multiple fibers. In the present embodiment, the strength layer 103 includes twisted yarns (e.g., Z yarns). However, the strength layer 103 may also comprise untwisted yarns. Strength layer 103 connects base layer 101 with ventilation layer 102. That is, the strength portion 110 is formed by sewing the base layer 101 and the ventilation layer 102 with the strength layer 103.
As shown in fig. 1 to 3 and 5, the strength portion 110 includes a toe strength portion 111 and a heel strength portion 112. A plurality of through holes h may be provided in the strength portion 110.
The toe strength portion 111 is disposed in the toe region R1. The outer edge of the toe strength portion 111 has a shape along the front end of the upper 10. The toe strength portion 111 has a shape curved so as to be convex toward the front end portion.
The heel strength portion 112 is disposed in the heel region R2. The rear end of the heel strength part 112 has a shape extending from the sole 5 to the foot part 10h 1. The heel strength part 112 has a shape gradually separated from the leg part 10h1 as it goes toward the toe region R1.
As shown in fig. 4, the vent part 120 has a single-layer part 120A and a double-layer part 120B.
The double layer portion 120B has only two layers of the base layer 101 and the ventilation layer 102. The ventilation layer 102 in the double-layered portion 120B is continuously connected to the ventilation layer 102 adjacent to the strength portion 110 of the double-layered portion 120B.
As shown in fig. 2, 3 and 5, the ventilation portion 120 includes a toe ventilation portion 121, a heel ventilation portion 122 and an intermediate ventilation portion 123. A plurality of through holes h may be provided in the vent part 120.
The toe vent 121 is disposed in the toe region R1. The heel ventilation portion 122 is disposed in the heel region R2. The intermediate ventilation portion 123 is disposed in the intermediate region R3. The toe vent 121 and the heel vent 122 may be omitted.
In the present embodiment, the toe vent portion 121, the heel vent portion 122, and the middle vent portion 123 are formed of only the single layer portion 120A. However, at least one of the toe vent portion 121, the heel vent portion 122, and the middle vent portion 123 may include the double layer portion 120B.
The ratio of the area of the ventilation portion 120 to the area of the strength portion 110 in the middle region R3 is larger than the ratio of the area of the ventilation portion 120 to the area of the strength portion 110 in the toe region R1 and the heel region R2.
As described above, in the footwear 1 according to the present embodiment, the base layer 101 constituting a part of the strength portion 110 and the ventilation portion 120 has a shape extending from the toe region R1 to the heel region R2, and therefore, it is possible to secure air permeability in the intermediate region R3 by the intermediate ventilation portion 123, secure rigidity in the toe region R1 by the toe strength portion 111, and secure rigidity in the heel region R2 by the heel strength portion 112 without performing bonding or sewing.
In the above embodiment, as shown in fig. 6, an opening h10 may be provided in the upper 10 in a region in front of the throat portion 10h2.
Alternatively, as shown in fig. 7, insertion holes h20 for inserting a shoelace may be provided in the inner sole covering portion 11 and the outer sole covering portion 12 of the upper 10 at positions around the throat portion 10h2.
(second embodiment)
Next, an upper 10 of footwear 1 according to a second embodiment of the present disclosure will be described with reference to fig. 8 and 9. In the second embodiment, only the portions different from the first embodiment will be described, and the description of the same structure, operation, and effect as those of the first embodiment will not be repeated.
In the present embodiment, the strength portion 110 further includes a plurality of intermediate strength portions 113 disposed in the intermediate region R3. Each intermediate strength portion 113 has a shape extending from the heel region R2 to the toe region R1. The plurality of intermediate strength portions 113 are disposed at intervals along the width direction of the footwear 1.
The intermediate ventilation portion 123 has a plurality of length ventilation portions 123a. Each of the long ventilation portions 123a has a shape extending from the heel region R2 to the toe region R1. The intermediate strength portions 113 and the longitudinal ventilation portions 123a are arranged alternately in the width direction. The longitudinal ventilation portion 123a may extend to the toe region R1 and the heel region R2.
As shown in fig. 9, base layer 101 is configured in such a manner as to constitute an outer surface of upper 10.
In the above-described aspect, since the flow path having the shape extending from the heel region R2 to the toe region R1 is formed between the pair of intermediate strength portions 113 that are adjacent to each other in the width direction between the foot in the footwear 1 and the base layer 101 of the upper 10, the air permeability in the intermediate region R3 can be effectively ensured.
(third embodiment)
Next, an upper 10 of footwear 1 according to a third embodiment of the present disclosure will be described with reference to fig. 10. In the third embodiment, only the portions different from the first embodiment will be described, and the description of the same structure, operation, and effect as those of the first embodiment will not be repeated.
In the present embodiment, the strength portion 110 further includes a plurality of inner strength portions 114 and a plurality of outer strength portions 115.
The plurality of inner strength portions 114 are disposed in the middle region R3 of the inner foot covering portion 11. Each medial strength portion 114 has a shape gradually inclined toward the toe region R1 from the sole 5 toward the throat portion 10h2.
The plurality of outer strength portions 115 are disposed in the middle region R3 of the outer foot covering portion 12. Each of the outer side strength portions 115 has a shape gradually inclined toward the heel region R2 from the sole 5 toward the throat portion 10h2.
The middle ventilation portion 123 includes a plurality of inner inclined ventilation portions 123b and a plurality of outer inclined ventilation portions 123c.
Each of the inner inclined ventilation portions 123b is formed in the inner foot covering portion 11. Each of the inner inclined ventilation portions 123b is more preferably formed in front of the insertion portion 10h1 in the inner foot covering portion 11. Each of the inner inclined ventilation portions 123b has a shape gradually inclined toward the toe region R1 from the sole 5 toward the throat portion 10h2. The inner strength portions 114 and the inner inclined ventilation portions 123b are arranged so as to be alternately arranged in the longitudinal direction.
Each outer oblique ventilation portion 123c is formed in the outer foot covering portion 12. Each of the outer inclined ventilation portions 123c has a shape that gradually inclines toward the heel region R2 from the sole 5 toward the throat portion 10h2. The outer strength portions 115 and the outer inclined ventilation portions 123c are arranged so as to be alternately arranged in the longitudinal direction.
In this configuration, the inside of the footwear 1 can be effectively ventilated when the foot is swung. More specifically, when the footwear 1 is inclined at 45 ° with respect to the ground in the swing state of the foot during running, the inner inclined ventilation portions 123b are parallel to the air flow direction, and the outer inclined ventilation portions 123c are orthogonal to the air flow direction. This allows effective ventilation of the interior of the footwear 1. Therefore, heat inside the footwear 1 can be efficiently dissipated.
(fourth embodiment)
Next, an upper 10 of footwear 1 according to a fourth embodiment of the present disclosure will be described with reference to fig. 11. In the fourth embodiment, only the portions different from the first embodiment will be described, and descriptions of the same structure, operation, and effect as those of the first embodiment will not be repeated.

The intermediate ventilation portion 123 includes a plurality of strip-shaped ventilation portions 123d arranged on the side of the throat portion 10h2. The plurality of strip-shaped ventilation portions 123d are disposed in the intermediate region R3 of the inner foot covering portion 11 and the intermediate region R3 of the outer foot covering portion 12. Each of the band-shaped ventilation portions 123d has a shape extending from the throat portion 10h2 to the sole 5 in the height direction.
The strip-shaped strength portions 116 and the strip-shaped ventilation portions 123d are arranged so as to be alternately arranged in the longitudinal direction. The length of the strip-shaped strength portion 116 in the longitudinal direction is longer than the length of the strip-shaped ventilation portion 123d in the longitudinal direction.
In the above-described aspect, when shear stress occurs in the height direction of the footwear 1 in the intermediate region R3 of the upper 10 during operation, the strip-shaped ventilation portions 123d deform, and therefore shear deformation in the intermediate region R3 is permitted. Further, the "height direction" includes not only a direction orthogonal to the longitudinal direction of the footwear 1 but also a direction inclined with respect to the direction.
(fifth embodiment)
Next, an upper 10 of footwear 1 according to a fifth embodiment of the present disclosure will be described with reference to fig. 12. In the fifth embodiment, only the portions different from the first embodiment will be described, and descriptions of the same structure, operation, and effect as those of the first embodiment will not be repeated.
In the present embodiment, the intermediate ventilation portion 123 includes an inner ventilation portion 123e and an outer ventilation portion 123f. The inner vent 123e and the outer vent 123f include the single-layer part 120A.

In the above-described aspect, when the portion in front of the throat portion 10h2 in the upper 10 is bent, each front strength portion 117 is deformed, and therefore, the occurrence of wrinkles in the portion in front can be suppressed.
The embodiments disclosed herein are illustrative in all respects, and not restrictive. The scope of the present invention is indicated by the scope of the claims, not by the description of the embodiments, and includes meanings equivalent to the scope of the claims and all modifications within the scope.
For example, in each of the above embodiments, the throat portion 10h2 may be omitted, and the upper 10 may have a so-called sock structure. In this case, the positions of the respective portions (the opening portion h10, the intermediate ventilation portion 123, the front ventilation portion 123g, the inner strength portion 114, the front strength portion 117, and the like) provided around the slit portion 10h2 are the same as those in the case where the slit portion 10h2 is provided.
[ form ]
It will be understood by those skilled in the art that the above exemplary embodiments are specific examples of the following forms.
In the footwear, the base layer constituting part of the strength portion and the ventilation portion has a shape extending from the toe region to the heel region, and therefore, it is possible to secure air permeability in the middle region by the middle ventilation portion, secure rigidity in the toe region by the toe strength portion, and secure rigidity in the heel region by the heel strength portion without performing bonding or sewing.
In addition, it is preferable that the ratio of the area of the ventilation portion 120 to the area of the strength portion 110 in the intermediate region R3 is larger than the ratio of the area of the ventilation portion 120 to the area of the strength portion 110 in the toe region R1 and the heel region R2.
Thereby, the effect can be effectively obtained. Specifically, in the intermediate region in contact with the instep where the sweat generation is relatively large, the area of the ventilation portion is large, and therefore, the ventilation performance is ensured, and in the toe region and the heel region where the strength is required, the area of the strength portion is large, and therefore, the rigidity is ensured.
Moreover, the upper 10 may have: an inner leg covering part 11 covering at least a part of the inner leg surface of the leg; a foot outer covering part 12 for covering at least a part of the foot outer surface; a pin portion 10h1 provided between the inner foot cover portion and the outer foot cover portion in the width direction of the footwear, for allowing a foot to enter and exit; and a throat portion 10h2 provided in the intermediate region and extending forward in the longitudinal direction from the pin portion.
The strength portion 110 may further include a plurality of band-shaped strength portions 116, the plurality of band-shaped strength portions 116 being disposed on a side of the throat portion, each band-shaped strength portion 116 of the plurality of band-shaped strength portions having a shape extending from the throat portion to the sole along the height direction of the footwear, the intermediate vent portion 123 may include a plurality of band-shaped vent portions 123d, the plurality of band-shaped vent portions 123d being disposed on a side of the throat portion, each band-shaped vent portion 123d of the plurality of band-shaped vent portions having a shape extending from the throat portion to the sole along the height direction, and the band-shaped strength portions and the band-shaped vent portions being disposed so as to be alternately arranged in the length direction.
In the above aspect, when shear stress is generated in the height direction of the footwear in the intermediate region of the upper during operation, each of the strip-shaped ventilation portions deforms, and therefore shear deformation in the intermediate region is permitted. Further, the "height direction" includes not only a direction orthogonal to the longitudinal direction of the footwear but also a direction inclined with respect to the direction.
In this case, it is preferable that the length of the band-shaped strength portion in the longitudinal direction is greater than the length of the band-shaped ventilation portion in the longitudinal direction.
Thereby, the effect can be obtained more effectively.
Also, the intermediate ventilation part 123 may include: an inner ventilation portion 123e disposed in the inner leg covering portion; and a lateral ventilation portion 123f disposed in the outer foot covering portion, the medial ventilation portion 123e having a shape extending from a rear end portion of the throat portion to the sole along the width direction, and the lateral ventilation portion 123f having a shape extending from a front end portion of the throat portion to the sole along the width direction.
In the above aspect, since the portion where wrinkles are likely to occur when the upper is bent includes the ventilation portion having relatively high flexibility, the occurrence of wrinkles at the portion when the upper is bent can be suppressed. Therefore, the fitting property to the foot during the operation is improved.
The strength portion 110 may include a plurality of front strength portions 117, the plurality of front strength portions 117 may be disposed in front of the throat portion, each front strength portion 117 of the plurality of front strength portions may have a shape extending in the width direction, the vent portion 120 may include a plurality of front vent portions 123g, the plurality of front vent portions 123g may be disposed in front of the throat portion, each front vent portion 123g of the plurality of front vent portions may have a shape extending in the width direction, and the front strength portions and the front vent portions may be disposed so as to be alternately arranged in the longitudinal direction.
In this form, the upper is easily bent at a portion in front of the throat portion.
Further, the strength portion 110 may include a plurality of front strength portions 117, the plurality of front strength portions 117 may be disposed in front of the throat portion, the vent portion 120 may include a plurality of front vent portions 123g, the plurality of front vent portions 123g may be disposed in front of the throat portion, and the plurality of front vent portions 123g may include: a plurality of first inclined ventilation portions 123g1 inclined inward in the width direction as they go forward in the longitudinal direction; and a plurality of second inclined ventilation portions 123g2 inclined outward in the width direction toward the front in the longitudinal direction, each of the plurality of front strength portions 117 including a portion surrounded by the plurality of first inclined ventilation portions and the plurality of second inclined ventilation portions.
In the above aspect, when the portion in front of the throat portion of the upper is bent, each front strength portion is deformed, and therefore, the occurrence of wrinkles in the portion in front can be suppressed.
The strength portion 110 may further include a plurality of medial strength portions 114, the plurality of medial strength portions 114 being disposed in the middle region of the inner foot covering portion, each medial strength portion 114 of the plurality of medial strength portions having a shape that gradually inclines toward the toe region from the sole toward the throat portion, the middle ventilation portion 123 having a plurality of medial oblique ventilation portions 123b, the plurality of medial oblique ventilation portions 123b being formed in the inner foot covering portion, respectively, and having a shape that gradually inclines toward the toe region from the sole toward the throat portion, the medial strength portions and the medial oblique ventilation portions being disposed so as to be alternately arranged in the longitudinal direction.
In the above aspect, the inside of the footwear can be effectively ventilated when the foot is swung.
The strength portion 110 may further include a plurality of intermediate strength portions 113, the plurality of intermediate strength portions 113 being disposed in the intermediate region, each intermediate strength portion 113 of the plurality of intermediate strength portions having a shape extending from the heel region to the toe region, the intermediate ventilation portion 123 having a plurality of length ventilation portions 123a, the plurality of length ventilation portions 123a each having a shape extending from the heel region to the toe region, the intermediate strength portions and the length ventilation portions being disposed so as to be alternately arranged in the width direction, and the base layer 101 being disposed so as to constitute an outer surface of the upper 10.
In this aspect, since the flow path from the heel region to the toe region is formed between the foot and the base layer in the footwear and between the intermediate strength portions adjacent to each other in the width direction, the air permeability in the intermediate region can be effectively ensured.
Also, the vent part 120 may include: a single layer part 120A having only the base layer 101; and a double layer part 120B having only two layers of the base layer 101 and the ventilation layer 102, the double layer part being disposed in front of the slit part.
