Description

Field

The present disclosure relates to an upper and a shoe including the upper.

Background

Conventionally, to enhance the design of the upper by decorating the upper, or to control physical properties such as tensile rigidity and abrasion strength of the upper, embroideries are formed on the upper (see Patent Literature 1, for example).
The upper includes a cloth-like base member. The base member normally includes one or more layers each including a front surface and a back surface. As disclosed in Patent Literature 1, a conventional embroidery is formed by sewing yarns onto the base member after the base member is manufactured. Hereinafter, a "yarn" fixed to the base member will be referred to as a "linear member".
To widen the range of expression in the design of the upper and to partially change the physical properties of the upper, the positions of the linear members in the base member are preferably selectable as desired.

Summary

Technical Problem

With the conventional embroideries, however, in a case where the base member is formed with one layer, the linear members are disposed over the front surface, the back surface, and the inside of the layer of the base member without fail, and, in a case where the base member is formed with two or more layers, the linear members are disposed over the respective layers of the base member without fail. Therefore, the conventional embroideries have a problem in that the degree of freedom in selecting the positions of the linear members in the base member is low.
The present disclosure has been made in view of the above, and aims to obtain an upper capable of increasing the degree of freedom in selecting the positions of linear members in the base member.

Solution to Problem

In order to solve the above problem and achieve the object, an upper comprising: a cloth-like base member that includes one layer having a front surface and a back surface facing in an opposite direction from the front surface; and a plurality of linear members that are disposed side by side in the base member and are formed independently of each other, wherein each linear member of the plurality of linear members includes: a plurality of fixed portions that are fixed to the layer, and are disposed at a distance from each other; and a plurality of unfixed portions that are located between adjacent ones of the fixed portions, and are not fixed to the layer, each linear member of the plurality of linear members is folded back and forth in an in-plane direction of the layer, and a plurality of the unfixed portions continuous via the fixed portions is disposed to be exposed through at least one of the front surface or the back surface of the layer, or is disposed inside the layer.

Description of Embodiments

The following is a detailed description of embodiments of an upper and a shoe according to the present disclosure, with reference to the drawings. Note that the present disclosure is not limited by this embodiments. In the description below, the same portions are denoted by the same reference numerals, and explanation of them will be repeated.

(First Embodiment)

FIG. 1 is a developed view illustrating the upper 2 of a shoe 1 according to a first embodiment of the present disclosure. In the drawings including FIG. 1, only the shoe 1 for the left foot is illustrated. Since the shoe 1 for the left foot has a structure symmetrical with the shoe for the right foot, only the shoe 1 for the left foot is described in the present embodiment, and explanation of the shoe 1 for the right foot is not made herein. In the description below, a direction in which a shoe center axis C, which is a perpendicular line extending through the center of the shoe 1 in a planar view of the shoe 1, extends will be referred to as the longitudinal direction, and a direction orthogonal to the longitudinal direction in a planar view of the shoe 1 will be referred to as the foot width direction.
In the description below, of the longitudinal direction, the direction from the heel toward the toe of the shoe 1 will be referred to as the fore direction, and the direction from the toe toward the heel of the shoe 1 will be referred to as the rear direction.
In the description below, the median side in the anatomical normal position of the foot will be referred to as the medial foot side, and the side opposite to the median side in the anatomical normal position of the foot will be referred to as the lateral foot side. That is, the side closer to the median line in the anatomical normal position will be referred to as the medial foot side, and the side farther from the median line in the anatomical normal position will be referred to as the lateral foot side.
In the description below, the vertical direction means the direction orthogonal to both the longitudinal direction and the foot width direction, unless otherwise specified.
The upper 2 includes an upper fore foot position R1 covering the fore foot position of a foot of a wearer having a standard body shape, an upper middle foot position R2 covering the middle foot position of the foot of the wearer having a standard body shape, and an upper rear foot position R3 covering the rear foot position of the foot of the wearer having a standard body shape. The upper fore foot position R1, the upper middle foot position R2, and the upper rear foot position R3 are successively present in this order in the direction from the fore to the rear of the upper 2.
The line that extends in the foot width direction and passes through a position corresponding to about 30% to 40% of the dimension of the upper 2 in the longitudinal direction of the upper 2 from the fore end is defined as a first boundary line S1, and the line that extends the foot width direction and passes through a position corresponding to about 73% to 83% of the dimension of the upper 2 in the longitudinal direction from the fore end of the upper 2 is defined as a second boundary line S2. The first boundary line S1 is a line that extends substantially along the MP joint of the wearer having a standard body shape. The second boundary line S2 is a line that extends substantially along the Chopart's joint of the wearer having a standard body shape. The upper fore foot position R1 is a portion located on the fore side of the first boundary line S1. The upper middle foot position R2 is a portion located between the first boundary line S1 and the second boundary line S2. The upper rear foot position R3 is a portion located on the rear side of the second boundary line S2.
FIG. 2 is a perspective view illustrating the shoe 1 according to the first embodiment of the present disclosure. The shoe 1 is preferably a shoe for running, but may be a shoe for some other sport, a shoe for walking, a shoe for climbing, or the like. The shoe 1 includes the upper 2 and a sole 3.
The upper 2 is located above the sole 3. The upper 2 includes a base member 20, a linear member placement region 21, a shoe tongue 23, and a shoelace 24.
The base member 20 covers a portion on the instep side of the foot of the wearer. A foot insertion opening 20a and a throat portion 20b are disposed at an upper portion of the base member 20. The foot insertion opening 20a is an opening for allowing the foot of the wearer to enter the inside of the base member 20. The throat portion 20b is an opening that communicates with the foot insertion opening 20a and extends in the fore direction from the foot insertion opening 20a. A plurality of lace hole portions 20c separated from one another in the longitudinal direction is disposed on both side edges of the throat portion 20b in the foot width direction. In FIG. 2, only the lace hole portions 20c disposed at the side edge on the lateral foot side of the throat portion 20b are illustrated. The lace hole portions 20c only needs to enable the shoelace 24 to pass therethrough. The lace hole portions 20c are through holes penetrating the base member 20 in the thickness direction of the base member 20, for example.
In FIGS. 1 and 2, to clarify the range of the linear member placement region 21, dot hatching is applied to the linear member placement region 21. The linear member placement region 21 plays a role of decorating the upper 2 and a role of partially changing the physical properties of the upper 2. Details of the base member 20 and the linear member placement region 21 will be described later.
The shoe tongue 23 is a member for protecting the instep of the foot of the wearer. The shoe tongue 23 covers the throat portion 20b inside the base member 20. The shoe tongue 23 is secured to the base member 20 by stitching, welding, bonding, or a combination thereof. The base member 20 and the shoe tongue 23 are knitted fabrics in which yarns are rolled into a chain-like shape and chain-like portions are hooked to one another to form a cloth, woven fabrics in which warp yarns and weft yarns cross each other at a certain angle to form a cloth, or compositions in which three or more braid yarns cross one another and run obliquely to form a cloth, for example. In particular, in the shoe 1 in which air permeability and lightweight properties are required, the base member 20 and the shoe tongue 23 are preferably double raschel warp knitted fabrics knitted with polyester yarns. Note that the materials of the base member 20 and the shoe tongue 23 are not limited to the materials mentioned as examples.
The shoelace 24 is a string-like member that passes alternately through the lace hole portions 20c disposed at one side edge in the foot width direction of the throat portion 20b and the lace hole portions 20c disposed at the other side edge in the foot width direction. The shoelace 24 is detachably attached to the base member 20.
Note that, in the present embodiment, the upper 2 including the shoe tongue 23 and the shoelace 24 is described as an example, but the upper 2 may have a monosock structure in which the portion corresponding to the shoe tongue 23 is integrated with the ankle portion of the base member 20. Also, the means for bringing the base member 20 into close contact with the foot may be a hook-and-loop fastener, for example, instead of the shoelace 24. In a case where the means for bringing the base member 20 into close contact with the foot is a hook-and-loop fastener, the lace hole portions 20c are not disposed in the base member 20.
The sole 3 is located below the upper 2. The sole 3 covers the sole of the wearer. The sole 3 is secured to the base member 20 by stitching, welding, bonding, or a combination thereof. The sole 3 includes an outsole 30 and a midsole 31. The lower face of the outsole 30 serves as a ground contact face 30a to be in contact with the ground. The midsole 31 is located on the upper face of the outsole 30, and has cushioning properties. Note that the outsole 30 may be integrated with the midsole 31. The outsole 30 integrated with the midsole 31 is also referred to as the "unisole".
Although not illustrated, the sole 3 includes an inner sole that covers the lower opening of the base member 20. The inner sole is secured to the upper face of the midsole 31 by adhesion or welding. The inner sole is secured to the lower edge of the base member 20 by stitching. Although not illustrated, the shoe 1 may include an insole. In a case where the shoe 1 includes an insole, the insole is placed on the sole 3 inside the upper 2. Note that the sole 3 may have a structure that excludes the inner sole.
Next, the base member 20 and the linear member placement region 21 are described in greater detail, with reference to FIGS. 1 to 4. FIG. 3 is a cross-sectional view taken along the line III-III illustrated in FIG. 2. FIG. 4 is a view when the upper 2 is viewed from an arrow X illustrated in FIG. 3.
As illustrated in FIG. 1, the base member 20 includes the upper fore foot position R1, the upper middle foot position R2, and the upper rear foot position R3. As illustrated in FIG. 2, the base member 20 is disposed over the entire region of the upper 2, except for the shoe tongue 23 and the shoelace 24. As illustrated in FIG. 3, the base member 20 is a cloth-like member having one layer 20d. The layer 20d includes a front surface 20e, and a back surface 20f facing in the opposite direction from the front surface 20e.
The front surface 20e is the surface facing the outside of the upper 2. In other words, the front surface 20e is the surface located on the opposite side from the foot of the wearer. The back surface 20f is the surface facing the inside of the upper 2. In other words, the back surface 20f is the surface located on the side of the foot of the wearer. As illustrated in FIG. 4, in the present embodiment, the base member 20 is a knitted fabric in which a plurality of yarns 20g is knitted. The base member 20 includes a plurality of wales 20h extending in a first direction and a plurality of courses 20i extending in a second direction orthogonal to the first direction. One of the first direction and the second direction coincides with the longitudinal direction, and the other one of the first direction and the second direction coincides with the foot width direction.
As illustrated in FIG. 1, the linear member placement regions 21 are disposed in the upper fore foot position R1 and the upper middle foot position R2 of the base member 20. In the present embodiment, the linear member placement regions 21 are disposed at the positions indicated by dot hatching in FIG. 1. The positions of the linear member placement regions 21 are not limited to the illustrated examples. As illustrated in FIG. 4, the linear member placement regions 21 are the regions in which a plurality of linear members 22 are disposed. The plurality of linear members 22 is arranged side by side in the base member 20 and are disposed independently of one another. The plurality of linear members 22 is arranged in the in-plane direction of the base member 20. Each linear member of the plurality of linear members 22 is folded back and forth in the in-plane direction of the base member 20. The linear members 22 have a variation range of 3 mm or wider in the longitudinal direction or the foot width direction.
The linear members 22 and the yarns 20g of the base member 20 are yarns obtained by bundling a plurality of fibers, linear resins, twisted yarns, or the like, for example. The materials of the linear members 22 and the yarns 20g of the base member 20 are polyester, polyurethane-based thermoplastic elastomer, polyurethane, nylon, spandex, Kevlar (registered trademark), ultra-high molecular weight polyethylene, single covered Yarn (SCY) or double covered Yarn (DCY) covered with polyurethane, or the like, for example.
The material of some or all of the plurality of linear members 22 and the material of the yarns 20g of the base member 20 may be the same as each other, or be different from each other. For example, the material of at least one linear member of the plurality of linear members 22 and the material of the yarns 20g of the base member 20 may be different from each other. The width of some or all of the plurality of linear members 22 and the width of the yarns 20g of the base member 20 may be the same as each other, or be different from each other. For example, the width of at least one linear member of the plurality of linear members 22 and the width of the yarns 20g of the base member 20 may be different from each other.
The melting point of the material of at least one linear member of the plurality of linear members 22 is preferably lower than the melting point of the material of the base member 20. For example, some or all of the plurality of linear members 22 may be yarns having a lower melting point than that of the yarns 20g of the base member 20. Also, some or all of the plurality of linear members 22 may be composite yarns containing fibers having different melting points. In particular, a core-in-sheath structure in which a core material (fiber) having a high melting point is covered with a low-melting-point material is preferably used for some or all of the plurality of linear members 22. In this arrangement, when the linear members 22 are subjected to a heat treatment at a temperature equal to or higher than the melting point of the low-melting-point material, the low-melting-point material is locally melted and solidified. Thus, the tensile rigidity of the upper 2 can be further enhanced.
Each linear member of the plurality of linear members 22 includes a plurality of fixed portions 22a fixed to the layer 20d, and a plurality of unfixed portions 22b not fixed to the layer 20d. The fixed portions 22a are disposed apart from one another. The fixed portions 22a are portions that are passed through aperture portions 20j disposed in the base member 20 and are entangled with the yarns 20g. The aperture portions 20j are circular holes. The aperture portions 20j are disposed, being entangled with some of the adjacent loops of the base member 20. The unfixed portions 22b are disposed apart from one another. The unfixed portions 22b are located between the adjacent fixed portions 22a.
The length L of the unfixed portions 22b in the first direction may be set as appropriate, but is preferably greater than 3 mm. Each unfixed portion of the plurality of unfixed portions 22b is disposed across one wale of the base member 20, and is disposed across two courses of the base member 20. The number of courses of the base member 20 crossed by the unfixed portions 22b is larger than the number of wales of the base member 20 crossed by the unfixed portions 22b.
As illustrated in FIG. 3, the plurality of linear members 22 is disposed to be exposed through the front surface 20e of the layer 20d, or is disposed to be exposed through the back surface 20f of the layer 20d. FIG. 3 illustrates a state in which two linear members 22 disposed separately are arranged in the length direction of the linear members 22. In the description below, in a case where the two linear members 22 are distinguished, the one linear member 22 indicated by a dot-and-dash line will be referred to as the first linear member 22A, and the other linear member 22 indicated by a dashed line will be referred to as the second linear member 22B.
The plurality of unfixed portions 22b continuous via the fixed portions 22a in the first linear member 22A is disposed to be exposed through the front surface 20e of the layer 20d. The unfixed portions 22b of the first linear member 22A are exposed through the front surface 20e of the base member 20 located on the opposite side from the foot of the wearer. In the second linear member 22B, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the back surface 20f of the layer 20d. The unfixed portions 22b of the second linear member 22B are exposed through the back surface 20f of the base member 20 located on the side of the foot of the wearer. The material of the first linear member 22A and the material of the second linear member 22B may be the same as each other, or may be different from each other. The width of the first linear member 22A and the width of the second linear member 22B may be the same as each other, or may be different from each other.
In the manufacturing of the upper 2, the base member 20 and the linear member placement regions 21 can be formed in one step using a dedicated machine such as a warp knitting machine.
Next, the effects of the upper 2 and the shoe 1 according to the present embodiment are described.
FIG. 5 is a cross-sectional view illustrating the upper 110 of a shoe 100 according to a comparative example, and is a view illustrating a state in which embroideries are disposed on the upper 110 in which the layer 20d of the base member 20 is a single layer. As illustrated in FIG. 5, in a conventional embroidery, the unfixed portions 22b of a linear member 22 are alternately exposed through the front surface 20e and the back surface 20f of the layer 20d. That is, in the conventional embroidery, when the unfixed portions 22b of a linear member 22 are exposed through the front surface 20e of the layer 20d, the linear member 22 passes through the inside of the layer 20d, and the unfixed portions 22b of the linear member 22 are also exposed through the back surface 20f of the layer 20d without fail, so that the linear member 22 is disposed across the front surface 20e, the back surface 20f, and the inside of the layer 20d of the base member 20 without fail.
In the present embodiment, as illustrated in FIG. 3, each linear member of the plurality of linear members 22 includes a plurality of fixed portions 22a that are fixed to the layer 20d and are disposed apart from each other, and a plurality of unfixed portions 22b that are located between the adjacent fixed portions 22a and are not fixed to the layer 20d. In the present embodiment, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the layer 20d, or is disposed to be exposed through the back surface 20f of the layer 20d. With this arrangement, the plurality of unfixed portions 22b of one linear member 22 can be continuously exposed through the front surface 20e of the layer 20d, and the plurality of unfixed portions 22b of one linear member 22 can be continuously exposed through the back surface 20f of the layer 20d. Thus, the degree of freedom in selecting the positions of the linear members 22 in the base member 20 can be made higher than those with conventional embroideries.
In a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the layer 20d, any design can be freely applied to the appearance of the upper 2. Further, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the layer 20d, and in a case where the linear members 22 having high abrasion strength are used, the abrasion strength and the tensile rigidity of the outer surface of the upper 2 can be enhanced while the feeling to be felt by the wearer touching the base member 20 with the foot is maintained as the feeling of touching the upper 2. In a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the back surface 20f of the layer 20d, the unfixed portions 22b do not affect the design of the upper 2, or hardly affects the design of the upper 2. Thus, the design of the base member 20 is easily maintained as the design of the appearance of the upper 2. Furthermore, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the back surface 20f of the layer 20d, and in a case where the linear members 22 having high abrasion strength are used, the abrasion strength and the tensile rigidity of the inner surfaces of the upper 2 can be enhanced. Further, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the back surface 20f of the layer 20d, and in a case where the linear members 22 formed with a material having a pleasant feeling are used, the feeling to be felt by the foot of the wearer touching the linear members 22 can be enhanced. That is, as the positions of the linear members 22 in the base member 20 can be selected as appropriate in the present embodiment, the physical properties of the upper 2 can be partially changed freely while the range of expression of the design of the upper 2 is widened.
As illustrated in FIG. 5, in a conventional embroidery, in a case where the unfixed portions 22b are seen through the front surface 20e of the layer 20d, the unfixed portions 22b are alternately exposed through the front surface 20e and the back surface 20f of the layer 20d, and therefore, irregularities appear on the back surface 20f of the layer 20d. Since the irregularities adversely affect the contact of the foot, it is necessary to bond a backing material to the back surface 20f of the layer 20d. In that case, however, the weight of the shoe 1 increases. In this regard, in a case where the unfixed portions 22b are seen through the front surface 20e of the layer 20d in the present embodiment as illustrated in FIG. 3, the plurality of unfixed portions 22b is continuously exposed through the front surface 20e of the layer 20d, like the first linear member 22A. Accordingly, irregularities do not appear on the back surface 20f of the layer 20d, and the upper 2 having a preferred feeling of foot contact can be provided without the use of any backing material.
Since the formation of the base member 20 and the formation of the linear member placement regions 21 illustrated in FIG. 3 can be performed in one step in the present embodiment, the number of manufacturing steps, the amount of waste material, and the like of the upper 2 can be reduced, and thus, the cost and the environmental load can be reduced.
To enhance the tensile rigidity of the upper 2 with the linear members 22 illustrated in FIG. 4, it is necessary to dispose each linear member 22 across two or more of the courses and two or more of the wales constituting the base member 20. In the case of a knitted fabric, the maximum size of the courses and the wales is about 3 mm, and therefore, the variation range of the linear members 22 is preferably 3 mm or wider as in the present embodiment.
To realize a variety of design and a variety of physical properties of the upper 2 as in the present embodiment by using a conventional technique for forming embroideries on the upper and welding yarns to the upper, a backing material and an adhesive are required. In the present embodiment, it is possible to realize a variety of design and a variety of physical properties of the upper 2 only with the linear members 22, and there is no need to use a backing material and an adhesive. Thus, it is possible to make the weight of the upper 2 lighter than that with a conventional technique.
In the present embodiment, as illustrated in FIG. 3, the first linear member 22A disposed to be exposed through the front surface 20e of the layer 20d, and the second linear member 22B disposed to be exposed through the back surface 20f of the layer 20d are disposed separately from each other. With this arrangement, it is possible to change the physical properties of the upper 2, by changing the material, the thickness, and the like of the first linear member 22A and the second linear member 22B.
In the case of a knitted fabric, the size of the stitches is 3 mm at the maximum. Since the length L of the unfixed portions 22b illustrated in FIG. 4 exceeds 3 mm in the present embodiment, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2.
When the thickness of at least one linear member of the plurality of linear members 22 illustrated in FIG. 4 and the thickness of the yarns 20g of the base member 20 are made different from each other, physical properties such as abrasion strength and tensile rigidity can be made different between the linear members 22 and the yarns 20g. Accordingly, the physical properties of the upper 2 at the portions where the linear members 22 are disposed, and the physical properties of the upper 2 at the portions where the linear members 22 are not disposed can be made different from each other.
When the material of at least one linear member of the plurality of linear members 22 illustrated in FIG. 4 and the material of the yarns 20g of the base member 20 are made different from each other, physical properties such as abrasion strength and tensile rigidity can be made different between the linear members 22 and the yarns 20g. Accordingly, the physical properties of the upper 2 at the portions where the linear members 22 are disposed, and the physical properties of the upper 2 at the portions where the linear members 22 are not disposed can be made different from each other.
In the present embodiment, as illustrated in FIG. 4, at least one unfixed portion of the plurality of unfixed portions 22b is disposed across two or more courses of the base member 20. Thus, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2, and the tensile rigidity of the upper 2 in the course direction can be increased.
In the present embodiment, as illustrated in FIG. 4, the number of courses of the base member 20 crossed by the unfixed portions 22b is larger than the number of wales of the base member 20 crossed by the unfixed portions 22b. Thus, in a case where the base member 20 is formed with a material that is easy to stretch, and the linear members 22 are formed with a material that is difficult to stretch, for example, an upper 2 that is easy to stretch in the wale direction (first direction) but is difficult to stretch in the course direction (second direction) can be manufactured.
Next, modifications of the first embodiment are described.
The two divided linear members 22 illustrated in FIG. 3 may be one linear member 22 as illustrated in FIG. 6. FIG. 6 is a cross-sectional view illustrating the upper 2 of a shoe 1 according to a first modification of the first embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2.
The linear member 22 is a single member having a first region 22c and a second region 22d. The first region 22c is a region in which a plurality of unfixed portions 22b continuous via fixed portions 22a is disposed to be exposed only through the front surface 20e of the layer 20d. The second region 22d is a region in which a plurality of unfixed portions 22b continuous via fixed portions 22a is disposed to be exposed only through the back surface 20f of the layer 20d.
Since the linear member 22 is a single member having the first region 22c and the second region 22d in this modification, it is possible to reduce the processing cost and the environmental load, compared with those in a case where the portion corresponding to the first region 22c and the portion corresponding to the second region 22d are formed separately from each other. Since the linear member 22 is a single member having the first region 22c and the second region 22d in this modification, when the first region 22c is pulled, tension can be applied to the second region 22d, and fitting between the foot and the upper 2 can be enhanced. Note that it is only required that at least one linear member of the plurality of linear members 22 is a single member having the first region 22c and the second region 22d.
In the present embodiment, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the layer 20d, or is arranged to be exposed through the back surface 20f of the layer 20d, as illustrated in FIG. 3. However, some unfixed portions 22b may be disposed inside the layer 20d as illustrated in FIG. 7. That is, the plurality of unfixed portions 22b continuous via the fixed portions 22a is only required to be exposed through at least either the front surface 20e or the back surface 20f of the layer 20d, or be disposed inside the layer 20d. FIG. 7 is a cross-sectional view illustrating the upper 2 of a shoe 1 according to a second modification of the first embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2.
As illustrated in FIG. 7, the configuration of the first linear member 22A is the same as that of the first embodiment. In this modification, the entire second linear member 22B is disposed inside the layer 20d. In a case where the entire second linear member 22B is disposed inside the layer 20d, the second linear member 22B also includes a plurality of fixed portions 22a and a plurality of unfixed portions 22b. The fixed portions 22a are portions interwoven with yarns 20g inside the layer 20d. The unfixed portions 22b are portions not interwoven with the yarns 20g inside the layer 20d. In the second linear member 22B, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the layer 20d. The unfixed portions 22b of the second linear member 22B are not exposed through the front surface 20e and the back surface 20f of the base member 20. As the formation of the base member 20 and the formation of the linear member placement regions 21 can be performed in one step in this modification, the linear members 22 can be disposed inside the layer 20d of the base member 20.
In a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the layer 20d, the unfixed portions 22b are somewhat visible when the exterior of the upper 2 is viewed, but a design similar to the base member 20 is easily maintained as the design of the appearance of the upper 2. Also, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the layer 20d, it is possible to enhance the tensile rigidity of the upper 2 while maintaining the feeling to be felt by the wearer touching the base member 20 with the foot, as the feeling of touching the upper 2. Depending on whether the positions of the plurality of unfixed portions 22b continuous via the fixed portions 22a are located on the front surface 20e of the layer 20d, the back surface 20f of the layer 20d, or inside the layer 20d, the design of the base member 20 can be used as it is or some other design can be applied to the base member 20, and the physical properties of the base member 20 can be used as they are or some other physical properties can be imparted to the base member 20.
Note that a linear member 22 to be exposed through the front surface 20e of the layer 20d and a linear member 22 to be disposed inside the layer 20d may be integrally formed. In the case of such a configuration, the linear members 22 are formed as a single member having a first region and a second region. The first region is a region in which a plurality of unfixed portions 22b continuous via fixed portions 22a is disposed to be exposed only through the front surface 20e of the layer 20d. The second region is a region in which a plurality of unfixed portions 22b continuous via fixed portions 22a is disposed only inside the layer 20d.
The linear members 22 can also be disposed on the front surface 20e of the layer 20d, inside the layer 20d, and on the back surface 20f of the layer 20d illustrated in FIG. 7. With this arrangement, the region is divided into a region in which the unfixed portions 22b can be clearly seen, a region in which the unfixed portions 22b can be somewhat seen, and a region in which the unfixed portions 22b cannot be seen. Accordingly, it is possible to express a design having a height difference not only in the in-plane direction of the upper 2 but also in the thickness direction of the upper 2. That is, a three-dimensional design including the thickness direction of the upper 2 and the in-plane direction of the upper 2 can be created.
For example, in a case where the layer 20d is a porous member such as a mesh, in a case where the thickness of the layer 20d is small, and in a case where the layer 20d is transparent, the unfixed portions 22b disposed inside the layer 20d and on the back surface 20f of the layer 20d might be visible. In such a case, the linear members 22 may be disposed on the front surface 20e of the layer 20d, inside the layer 20d, and on the back surface 20f of the layer 20d. With such arrangement, the visibility of the unfixed portions 22b changes depending on the positions of the unfixed portions 22b in the base member 20. Thus, the linear members 22 can be made to appear blurred, and a design having a height difference in the thickness direction of the upper 2 can be expressed.
The layout of the unfixed portions 22b is not limited to the example illustrated in FIG. 4, and may be changed as appropriate. For example, at least one unfixed portion of the plurality of unfixed portions 22b may be disposed across two or more wales of the base member 20, or two or more courses of the base member 20.
For example, the unfixed portions 22b may be arranged as illustrated in FIG. 8. FIG. 8 is a view illustrating the upper 2 of a shoe 1 according to a third modification of the first embodiment of the present disclosure, and is a view corresponding to a view of the upper 2 seen from the arrow X illustrated in FIG. 3. Each unfixed portion of a plurality of unfixed portions 22b is disposed across five wales of the base member 20, and is disposed across one course of the base member 20. The number of wales of the base member 20 crossed by the unfixed portions 22b is larger than the number of courses of the base member 20 crossed by the unfixed portions 22b. In this modification, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2. In this modification, in a case where the base member 20 is formed with a material that is easy to stretch, and the linear members 22 are formed with a material that is difficult to stretch, for example, an upper 2 that is easy to stretch in the course direction (second direction) but is difficult to stretch in the wale direction (first direction) can be manufactured. Note that the number of courses of the base member 20 crossed by the unfixed portions 22b and the number of wales of the base member 20 crossed by the unfixed portions 22b may be the same.
In the present embodiment, the base member 20 is a knitted fabric in which a plurality of yarns 20g is knitted. However, a woven fabric in which a plurality of yarns 20g is woven, or a composition in which a plurality of yarns 20g is combined may be used, for example.

(Second Embodiment)

A shoe 1A according to a second embodiment is now described with reference to FIGS. 9 and 10. FIG. 9 is a cross-sectional view illustrating the upper 2A of the shoe 1A according to the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2. FIG. 10 is a view illustrating the upper 2A of the shoe 1A according to the second embodiment of the present disclosure, and is a view corresponding to a view of the upper 2A seen from an arrow X illustrated in FIG. 9 . The shoe 1A according to the second embodiment differs from the shoe 1 according to the first embodiment in that the base member 20 has two or more layers 20d.
As illustrated in FIG. 9, the base member 20 is a cloth-like member having two or more layers 20d. The number of layers 20d of the base member 20 is three in the present embodiment, but may be changed as appropriate. The base member 20 includes a first layer 20k, a second layer 20m disposed at a distance from the first layer 20k, and a third layer 20n located between the first layer 20k and the second layer 20m.
The first layer 20k is located on the outermost side in the base member 20. In other words, the first layer 20k is the layer 20d farthest from the foot of the wearer in the base member 20. The second layer 20m is located on the innermost side in the base member 20. In other words, the second layer 20m is the layer 20d located closest to the side of the foot of the wearer in the base member 20. The third layer 20n is located between the first layer 20k and the second layer 20m. The third layer 20n is a layer 20d that connects the first layer 20k and the second layer 20m, and prevents the first layer 20k and the second layer 20m from coming into contact with each other. Although not illustrated in the drawings, the third layer 20n includes a portion connecting the first layer 20k and the second layer 20m. In the present embodiment, the third layer 20n includes a space formed between the first layer 20k and the second layer 20m. Each of the first layer 20k and the second layer 20m includes a front surface 20e, and a back surface 20f facing in the opposite direction from the front surface 20e.
The front surface 20e of the first layer 20k is a surface facing the outside of the upper 2A in the first layer 20k. In other words, the front surface 20e of the first layer 20k is a surface located on the opposite side from the foot of the wearer in the first layer 20k. The back surface 20f of the first layer 20k is a surface facing the inside of the upper 2A in the first layer 20k. In other words, in the first layer 20k, the back surface 20f of the first layer 20k is a surface located on the side of the foot of the wearer.
The front surface 20e of the second layer 20m is a surface facing the inside of the upper 2A in the second layer 20m. In other words, the front surface 20e of the second layer 20m is a surface located on the side of the foot of the wearer in the second layer 20m. The back surface 20f of the second layer 20m is a surface facing the outside of the upper 2A in the second layer 20m. In other words, the back surface 20f of the second layer 20m is a surface located on the opposite side from the foot of the wearer in the second layer 20m.
In the present embodiment, the surface of each layer 20d exposed to the inside or the outside of the upper 2A is the front surface 20e, and the surface of each layer 20d exposed to neither of the inside and the outside of the upper 2A is the back surface 20f. As illustrated in FIG. 10, in the present embodiment, the base member 20 is a knitted fabric in which a plurality of yarns 20g is knitted. The base member 20 includes a plurality of wales 20h extending in a first direction and a plurality of courses 20i extending in a second direction orthogonal to the first direction. One of the first direction and the second direction coincides with the longitudinal direction, and the other one of the first direction and the second direction coincides with the foot width direction.
As in the first embodiment described above, the linear member placement regions 21 are disposed in the upper fore foot position R1 and the upper middle foot position R2 of the base member 20. The linear member placement regions 21 are disposed at the positions indicated by dot hatching in FIG. 1. The positions of the linear member placement regions 21 are not limited to the illustrated examples. As illustrated in FIG. 10, the linear member placement regions 21 are the regions in which a plurality of linear members 22 is disposed. The plurality of linear members 22 is arranged side by side in the base member 20 and are disposed independently of one another. The plurality of linear members 22 is arranged in the in-plane direction of the base member 20. Each linear member of the plurality of linear members 22 is folded back and forth in the in-plane direction of the base member 20. The linear members 22 have a variation range of 3 mm or wider in the longitudinal direction or the foot width direction.
The linear members 22 and the yarns 20g of the base member 20 are yarns obtained by bundling a plurality of fibers, linear resins, twisted yarns, or the like, for example. The materials of the linear members 22 and the yarns 20g of the base member 20 are polyester, polyurethane-based thermoplastic elastomer, polyurethane, nylon, spandex, Kevlar (registered trademark), ultra-high molecular weight polyethylene, single covered Yarn (SCY) or double covered Yarn (DCY) covered with polyurethane, or the like, for example.
The material of some or all of the plurality of linear members 22 and the material of the yarns 20g of the base member 20 may be the same as each other, or be different from each other. For example, the material of at least one linear member of the plurality of linear members 22 and the material of the yarns 20g of the base member 20 may be different from each other. The width of some or all of the plurality of linear members 22 and the width of the yarns 20g of the base member 20 may be the same as each other, or be different from each other. For example, the width of at least one linear member of the plurality of linear members 22 and the width of the yarns 20g of the base member 20 may be different from each other.
The melting point of the material of at least one linear member of the plurality of linear members 22 is preferably lower than the melting point of the material of the base member 20. For example, some or all of the plurality of linear members 22 may be yarns having a lower melting point than that of the yarns 20g of the base member 20. Also, some or all of the plurality of linear members 22 may be composite yarns containing fibers having different melting points. In particular, a core-in-sheath structure in which a core material (fiber) having a high melting point is covered with a low-melting-point material is preferably used for some or all of the plurality of linear members 22. In this arrangement, when the linear members 22 are subjected to a heat treatment at a temperature equal to or higher than the melting point of the low-melting-point material, the low-melting-point material is locally melted and solidified. Thus, the tensile rigidity of the upper 2 can be further enhanced.
Each linear member of the plurality of linear members 22 includes a plurality of fixed portions 22a fixed to at least one layer 20d, and a plurality of unfixed portions 22b not fixed to any layer 20d. The fixed portions 22a are disposed apart from one another. The fixed portions 22a are portions that are passed through aperture portions 20j disposed in the base member 20 and are entangled with the yarns 20g. The aperture portions 20j are circular holes. The aperture portions 20j are disposed, being entangled with some of the adjacent loops of the base member 20. The unfixed portions 22b are disposed apart from one another. The unfixed portions 22b are located between the adjacent fixed portions 22a.
The length L of the unfixed portions 22b in the first direction may be set as appropriate, but is preferably greater than 3 mm. Each unfixed portion of the plurality of unfixed portions 22b is disposed across one wale of the base member 20, and is disposed across two courses of the base member 20. The number of courses of the base member 20 crossed by the unfixed portions 22b is larger than the number of wales of the base member 20 crossed by the unfixed portions 22b.
As illustrated in FIG. 9, the plurality of linear members 22 is disposed to be exposed through the front surface 20e of at least one layer 20d. The plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the first layer 20k. The unfixed portions 22b are exposed through the front surface 20e of the first layer 20k farthest from the foot of the wearer in the base member 20.
In the manufacturing of the upper 2A, the base member 20 and the linear member placement regions 21 can be formed in one step using a dedicated machine such as a warp knitting machine.
Next, the effects of the upper 2A and the shoe 1A according to the present embodiment are described.
FIG. 11 is a cross-sectional view illustrating the upper 210 of a shoe 200 according to a comparative example, and is a view illustrating a state in which embroideries are disposed on the upper 210 in which the base member 20 has three layers 20d. As illustrated in FIG. 11, in a conventional embroidery, the unfixed portions 22b of a linear member 22 are alternately exposed through the front surface 20e of the first layer 20k and the front surface 20e of the second layer 20m. That is, in the conventional embroidery, when the unfixed portions 22b of a linear member 22 are exposed through the front surface 20e of the first layer 20k, the linear member 22 passes through the third layer 20n, and the unfixed portions 22b of the linear member 22 are also exposed through the front surface 20e of the second layer 20m without fail, so that the linear member 22 is disposed across the respective layers 20d of the base member 20 without fail.
In the present embodiment, as illustrated in FIG. 9, each linear member of the plurality of linear members 22 includes a plurality of fixed portions 22a that are fixed to at least one layer 20d and are disposed apart from each other, and a plurality of unfixed portions 22b that are located between the adjacent fixed portions 22a and are not fixed to any layer 20d. In the present embodiment, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of at least one layer 20d. With these arrangements, the plurality of unfixed portions 22b of one linear member 22 can be continuously exposed through the front surface 20e of a layer 20d as illustrated in FIG. 9, and thus, the degree of freedom in selecting the positions of the linear members 22 in the base member 20 can be made higher than that with a conventional embroidery.
In a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the first layer 20k farthest from the foot of the wearer in the base member 20, any design can be freely applied to the appearance of the upper 2A. Further, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the first layer 20k, and in a case where the linear members 22 having high abrasion strength are used, the abrasion strength and the tensile rigidity of the outer surface of the upper 2A can be enhanced while the feeling to be felt by the wearer touching the base member 20 with the foot is maintained as the feeling of touching the upper 2A.
As illustrated in FIG. 11, in a conventional embroidery, in a case where the unfixed portions 22b are seen through the front surface 20e of the first layer 20k, the unfixed portions 22b are alternately exposed through the front surface 20e of the first layer 20k and the front surface 20e of the second layer 20m, and therefore, irregularities appear on the front surface 20e of the second layer 20m. Since the irregularities adversely affect the contact of the foot, it is necessary to bond a backing material to the front surface 20e of the second layer 20m. In that case, however, the weight of the shoe 1A increases. In this regard, in a case where the unfixed portions 22b are seen through the front surface 20e of the first layer 20k in the present embodiment as illustrated in FIG. 9, the plurality of unfixed portions 22b is continuously exposed through the front surface 20e of the first layer 20k. Accordingly, irregularities do not appear on the front surface 20e of the second layer 20m, and the upper 2A having a preferred feeling of foot contact can be provided without the use of any backing material.
Since the formation of the base member 20 and the formation of the linear member placement regions 21 illustrated in FIG. 9 can be performed in one step in the present embodiment, the number of manufacturing steps, the amount of waste material, and the like of the upper 2A can be reduced, and thus, the cost and the environmental load can be reduced.
To enhance the tensile rigidity of the upper 2A with the linear members 22 illustrated in FIG. 10, it is necessary to dispose each linear member 22 across two or more of the courses and two or more of the wales constituting the base member 20. In the case of a knitted fabric, the maximum size of the courses and the wales is about 3 mm, and therefore, the variation range of the linear members 22 is preferably 3 mm or wider as in the present embodiment.
To realize a variety of design and a variety of physical properties of the upper 2A as in the present embodiment by using a conventional technique for forming embroideries on the upper and welding yarns to the upper, a backing material and an adhesive are required. In the present embodiment, it is possible to realize a variety of design and a variety of physical properties of the upper 2A only with the linear members 22, and there is no need to use a backing material and an adhesive. Thus, it is possible to make the weight of the upper 2A lighter than that with a conventional technique.
In the case of a knitted fabric, the size of the stitches is 3 mm at the maximum. Since the length L of the unfixed portions 22b illustrated in FIG. 10 exceeds 3 mm in the present embodiment, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2A.
When the thickness of at least one linear member of the plurality of linear members 22 illustrated in FIG. 10 and the thickness of the yarns 20g of the base member 20 are made different from each other, physical properties such as abrasion strength and tensile rigidity can be made different between the linear members 22 and the yarns 20g. Accordingly, the physical properties of the upper 2A at the portions where the linear members 22 are disposed, and the physical properties of the upper 2A at the portions where the linear members 22 are not disposed can be made different from each other.
When the material of at least one linear member of the plurality of linear members 22 illustrated in FIG. 10 and the material of the yarns 20g of the base member 20 are made different from each other, physical properties such as abrasion strength and tensile rigidity can be made different between the linear members 22 and the yarns 20g. Accordingly, the physical properties of the upper 2A at the portions where the linear members 22 are disposed, and the physical properties of the upper 2A at the portions where the linear members 22 are not disposed can be made different from each other.
In the present embodiment, as illustrated in FIG. 10, at least one unfixed portion of the plurality of unfixed portions 22b is disposed across two or more courses of the base member 20. Thus, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2A, and the tensile rigidity of the upper 2 in the course direction can be increased.
In the present embodiment, as illustrated in FIG. 10, the number of courses of the base member 20 crossed by the unfixed portions 22b is larger than the number of wales of the base member 20 crossed by the unfixed portions 22b. Thus, in a case where the base member 20 is formed with a material that is easy to stretch, and the linear members 22 are formed with a material that is difficult to stretch, for example, an upper 2A that is easy to stretch in the wale direction (first direction) but is difficult to stretch in the course direction (second direction) can be manufactured.
Next, modifications of the second embodiment are described.
As illustrated in FIG. 12, the number of layers 20d in the base member 20 may be two. FIG. 12 is a cross-sectional view illustrating the upper 2A of a shoe 1A according to a first modification of the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2. The base member 20 includes a first layer 20k, and a second layer 20m disposed in contact with the first layer 20k. The first layer 20k and the second layer 20m overlap each other in the thickness direction of the upper 2A. The back surface 20f of the first layer 20k and the back surface 20f of the second layer 20m are in contact with each other. The plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the first layer 20k. In this modification, the same effects as those of the above-described embodiments can also be achieved.
The layout of the unfixed portions 22b is not limited to the example illustrated in FIG. 9, and may be changed as appropriate. For example, the positions of the unfixed portions 22b may be positions as illustrated in FIG. 13. FIG. 13 is a cross-sectional view illustrating the upper 2A of a shoe 1A according to a second modification of the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2. The plurality of unfixed portions 22b continuous via the fixed portions 22a illustrated in FIG. 13 is disposed inside a layer 20d.
In this modification, an entire linear member 22 is disposed inside a layer 20d. In a case where an entire linear member 22B is disposed inside a layer 20d, the linear member 22 also includes a plurality of fixed portions 22a and a plurality of unfixed portions 22b. The fixed portions 22a are portions interwoven with yarns 20g inside the layer 20d. The unfixed portions 22b are portions not interwoven with the yarns 20g inside the layer 20d. The plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the first layer 20k. The unfixed portions 22b are not exposed through the front surface 20e and the back surface 20f of each layer 20d. As the formation of the base member 20 and the formation of the linear member placement regions 21 can be performed in one step in this modification, the linear members 22 can be disposed inside the layer 20d of the base member 20.
In a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the first layer 20k as in this modification, the unfixed portions 22b are somewhat visible when the exterior of the upper 2A is viewed, but a design similar to the base member 20 is easily maintained as the design of the appearance of the upper 2A. Also, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the first layer 20k, the tensile rigidity of the first layer 20k of the upper 2A can be enhanced.
The positions of the unfixed portions 22b may be positions as illustrated in FIG. 14. FIG. 14 is a cross-sectional view illustrating the upper 2A of a shoe 1A according to a third modification of the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2. The plurality of unfixed portions 22b continuous via the fixed portions 22a illustrated in FIG. 14 is disposed to be exposed through the front surface 20e of the first layer 20k, or is disposed inside the first layer 20k. FIG. 14 illustrates a state in which two linear members 22 disposed separately are arranged in the length direction of the linear members 22. In the description below, in a case where the two linear members 22 are distinguished, the one linear member 22 indicated by a dot-and-dash line will be referred to as the first linear member 22A, and the other linear member 22 indicated by a dashed line will be referred to as the second linear member 22B.
The plurality of unfixed portions 22b continuous via the fixed portions 22a in the first linear member 22A is disposed to be exposed through the front surface 20e of the first layer 20k. In the second linear member 22B, the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the first layer 20k. The material of the first linear member 22A and the material of the second linear member 22B may be the same as each other, or may be different from each other. The width of the first linear member 22A and the width of the second linear member 22B may be the same as each other, or may be different from each other.
In this modification, the same effects as any of the above-described embodiments and modifications can be achieved. Further, as the first linear member 22A disposed to be exposed through the front surface 20e of the first layer 20k and the second linear member 22B disposed inside the first layer 20k are disposed separately from each other, it is possible to partially change the physical properties of the upper 2A by changing the material, thickness, or the like of the first linear member 22A and the second linear member 22B.
Note that the two divided linear members 22 may be integrated into one linear member 22. That is, at least one linear member of the plurality of linear members 22 may be a single member that has a region in which the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed only through the front surface 20e of the first layer 20k, and a region in which the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed only inside the first layer 20k. With this arrangement, the processing cost and the environmental load can be reduced.
The positions of the unfixed portions 22b may be positions as illustrated in FIG. 15. FIG. 15 is a cross-sectional view illustrating the upper 2A of a shoe 1A according to a fourth modification of the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2.

Thus, the design of the first layer 20k of the base member 20 is easily maintained as the design of the appearance of the upper 2A. Furthermore, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed through the front surface 20e of the second layer 20m, and in a case where the linear members 22 having high abrasion strength are used, the abrasion strength and the tensile rigidity of the inner surfaces of the upper 2A can be enhanced.

Thus, the design of the first layer 20k of the base member 20 is easily maintained as the design of the appearance of the upper 2A. Further, in a case where the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed inside the second layer 20m, and in a case where the linear members 22 are used, the abrasion strength and the tensile rigidity of the second layer 20m of the upper 2A can be enhanced while the feeling to be felt by the wearer touching the base member 20 with the foot is maintained as the feeling of touching the upper 2A.
The positions of the unfixed portions 22b may be positions as illustrated in FIG. 17. FIG. 17 is a cross-sectional view illustrating the upper 2A of a shoe 1A according to a sixth modification of the second embodiment of the present disclosure, and is a view corresponding to a cross-sectional view taken along the line III-III illustrated in FIG. 2.

The width of the first linear member 22A and the width of the second linear member 22B may be the same as each other, or may be different from each other. In this modification, the same effects as any of the above-described embodiments and modifications can be achieved.

In this modification, the same effects as any of the above-described embodiments and modifications can be achieved.
Note that the three divided linear members 22 may be integrated into one linear member 22. That is, at least one linear member of the plurality of linear members 22 may be a single member that has a region in which the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed to be exposed only through the front surface 20e of the second layer 20m, a region in which the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed only inside the first layer 20k, and a region in which the plurality of unfixed portions 22b continuous via the fixed portions 22a is disposed only inside the third layer 20n. With this arrangement, the processing cost and the environmental load can be reduced.
As described above, in the present embodiment, the plurality of unfixed portions 22b continuous via the fixed portions 22a is only required to be exposed through the front surface 20e of at least one layer 20d, or be disposed inside at least one layer 20d. Depending on whether the positions of the plurality of unfixed portions 22b continuous via the fixed portions 22a are located on the front surface 20e of at least one layer 20d or inside at least one layer 20d, the design of the base member 20 can be used as it is or some other design can be applied to the base member 20, and the physical properties of the base member 20 can be used as they are or some other physical properties can be imparted to the base member 20. That is, as the positions of the linear members 22 in the base member 20 can be selected as appropriate in the present embodiment, the physical properties of the upper 2A can be partially changed freely while the range of expression of the design of the upper 2A is widened.
The linear members 22 can be disposed at least one of the following positions: on the front surface 20e of the first layer 20k, inside the first layer 20k, inside the third layer 20n, inside the second layer 20m, and on the front surface 20e of the second layer 20m illustrated in FIG. 25. With this arrangement, the region is divided into a region in which the unfixed portions 22b can be clearly seen, a region in which the unfixed portions 22b can be somewhat seen, and a region in which the unfixed portions 22b cannot be seen. Accordingly, it is possible to express a design having a height difference not only in the in-plane direction of the upper 2A but also in the thickness direction of the upper 2A. That is, a three-dimensional design including the thickness direction of the upper 2A and the in-plane direction of the upper 2A can be created.
For example, in a case where the layer 20d is a porous member such as a mesh, in a case where the thickness of the layer 20d is small, and in a case where the layer 20d is transparent, the unfixed portions 22b disposed inside the third layer 20n, inside the second layer 20m, and on the front surface 20e of the second layer 20m might be visible. In such a case, the linear members 22 may be disposed at least one of the following positions: on the front surface 20e of the first layer 20k, inside the first layer 20k, inside the third layer 20n, inside the second layer 20m, and on the front surface 20e of the second layer 20m. With such arrangement, the visibility of the unfixed portions 22b changes depending on the positions of the unfixed portions 22b in the base member 20. Thus, the linear members 22 can be made to appear blurred, and a design having a height difference in the thickness direction of the upper 2A can be expressed.
The layout of the unfixed portions 22b is not limited to the example illustrated in FIG. 10, and may be changed as appropriate. For example, at least one unfixed portion of the plurality of unfixed portions 22b may be disposed across two or more wales of the base member 20, or two or more courses of the base member 20.
For example, the number of wales of the base member 20 crossed by the unfixed portions 22b may be larger than the number of courses of the base member 20 crossed by the unfixed portions 22b. With such arrangement, a design that cannot be expressed with a knitted fabric can be applied to the appearance of the upper 2A. For example, in a case where the base member 20 is formed with a material that is easy to stretch, and the linear members 22 are formed with a material that is difficult to stretch, an upper 2A that is easy to stretch in the course direction (second direction) but is difficult to stretch in the wale direction (first direction) can be manufactured. Note that the number of courses of the base member 20 crossed by the unfixed portions 22b and the number of wales of the base member 20 crossed by the unfixed portions 22b may be the same.
In the present embodiment, the base member 20 is a knitted fabric in which a plurality of yarns 20g is knitted. However, a woven fabric in which a plurality of yarns 20g is woven, or a composition in which a plurality of yarns 20g is combined may be used, for example.
