Shoes

Abstract

The present invention provides a shoe that can reduce the possibility that the manufacturing process becomes complicated and the amount of waste increases even if the types are increased, by using a fiber sheet having a connecting portion where a surface layer and an inner layer are connected and a non-connecting portion where the surface layer and the inner layer are not connected to form an upper.

Description

TECHNICAL FIELD

[0001] The present application relates to a shoe upper and a shoe. BACKGROUND

[0002] Conventionally, a shoe is configured by a sole, an upper, and the like.

[0003] In the conventional sports shoes and the like, the upper is generally configured by a plurality of members such as a fiber sheet.

[0004] In such an upper, the fiber sheet which is cut in a manner suitable for a shoe mold when formed into a three-dimensional shape becomes a main constituent member.

[0005] As an example in which such a fiber sheet is provided to an upper, a shoe is disclosed in Patent Literature 1 in which a member configuring the upper of the shoe is a woven fabric.

[0006] Prior Art Documents

[0007] Patent Literature 1: International Publication No. WO2016 / 033051

[0008] The upper is required not only to have a prescribed property in terms of strength, air permeability, and the like, but also to be important in terms of appearance. In addition to the fiber sheet, there are other members such as a leather sheet which is different from the fiber sheet.

[0009] For example, in the upper of a shoe, a leather sheet is sewn to a fiber sheet to draw a pattern or a character on the surface.

[0010] In the appearance of a shoe, a leather sheet used to express a specific pattern, a character, or the like is generally produced by blanking a larger raw sheet using a die and a blanking method.

[0011] The leather sheet is not limited to a shape which can be blanked from a raw sheet without waste.

[0012] Therefore, the proportion of the raw sheet which is not effectively utilized as a member of a shoe and becomes a waste portion is not sufficiently low.

[0013] In addition, the leather sheet is utilized in a shoe for this purpose, and becomes a main cause of an increase in man-hours in a manufacturing process of a shoe.

[0014] Therefore, when shoes of a plurality of designs are manufactured, there is a case where the manufacturing process becomes complicated and a large amount of waste is discharged. SUMMARY

[0015] Problem to be Solved by the Invention

[0016] The present application has been made in view of the above problems, and an object thereof is to provide a shoe in which the possibility that an increase in a manufacturing process and an increase in discharge of waste are caused even if the number of kinds is increased is relatively low.

[0017] Means for solving the problem

[0035] An example of an embodiment of the present application will be described below with reference to the drawings.

[0036] In addition, an embodiment of the present application will be described below with reference to an athletic shoe as an example.

[0037] Figure 1 is a view showing a shoe of the present embodiment.

[0044] As shown in Figure 1 , the shoe 1 of the present embodiment has an upper portion 2 and a sole portion 3.

[0045] The sole portion 3 has a midsole 31 and an outsole 32.

[0046] The shoe 1 of the present embodiment has the outsole 32 at the lowermost side.

[0047] The outsole 32 of the present embodiment is, for example, a sheet shape, and is arranged at the lowermost portion of the shoe 1 in such a manner that the thickness direction becomes the vertical direction Z.

[0048] The shoe 1 has a midsole 31 between the upper 2 that covers the wearer's foot from the upper side and the outsole 32.

[0049] As shown in Figure 1 The shoe 1 of the present embodiment also has a tongue 4 and a shoelace 5.

[0050] The upper 2 of the present embodiment has a plurality of shoelace holes 2h in a portion that overlaps both end portions in the width direction of the tongue 4.

[0051] The upper 2 of the present embodiment has a fiber sheet 21.

[0052] The fiber sheet 21 of the present embodiment is formed in a three-dimensional shape along the outer surface of a shoe mold (not shown) and is arranged on the upper side of the sole 3.

[0053] The upper 2 of the present embodiment can have other components in addition to the fiber sheet 21.

[0054] The upper 2 of the present embodiment can also have a leather sheet 22 that is made of natural leather or artificial leather, or the like.

[0055] The upper 2 of the present embodiment has the leather sheet 22 arranged at a position where the shoelace hole 2h is provided.

[0056] The leather sheet 22 of the present embodiment is joined to the fiber sheet 21 in a state of being overlapped on the outer side of the fiber sheet 21.

[0057] The fiber sheet 21 can be a woven fabric, and can also be a textile fabric.

[0058] The fiber sheet 21 can also be a nonwoven fabric.

[0059] In the case where the fiber sheet 21 is a woven fabric, the weaving method can be warp knitting or weft knitting.

[0060] That is, the fiber sheet 21 can be a warp-knitted fabric or a weft-knitted fabric.

[0061] In the case where the fiber sheet 21 is a warp-knitted fabric, the weaving method can be tricot, raschel, or milanese.

[0062] In the case where the fiber sheet 21 is a weft-knitted fabric, the weaving method can be flat knitting, rib knitting, double knitting, or pearl knitting.

[0063] In the case where the fiber sheet 21 is a woven fabric, the weaving method can be plain weaving, tatting, or twill weaving.

[0064] In the case where the fiber sheet 21 is a non-woven fabric, the fiber sheet 21 can be a spun-bond non-woven fabric or a melt-blown non-woven fabric.

[0065] The fiber sheet 21 can also be a thermal-bonded non-woven fabric, a chemical-bonded non-woven fabric, or a spun-laced non-woven fabric.

[0066] The fiber sheet 21 can also be a needle-punched non-woven fabric, a spun-laced non-woven fabric, or a stitch bonded non-woven fabric.

[0067] The fiber that becomes the fiber sheet raw material is not particularly limited in kind, and for example, synthetic resin fibers such as polypropylene, polyethylene, polyester (polyethylene terephthalate, polybutylene terephthalate, copolymer polyester, etc.), polyamide (aliphatic polyamide, aromatic polyamide, etc.), fluorocarbon polymer (polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkyl ether copolymer, polyvinylidene fluoride, etc.) can be cited.

[0068] The fiber can also be composed of natural fibers such as cotton, hemp, bamboo, wool, silk, rock wool, etc.

[0069] The fiber can be a regenerated fiber such as cupra fiber, rayon fiber, etc., or a semi-synthetic fiber such as acetate rayon, etc.

[0070] The fiber can also be a metal fiber such as steel wool, etc.

[0071] The fiber need not be a single structure, and for example, can also be a fiber having a core-sheath structure, a side-by-side structure, or a multi-core structure.

[0072] The fiber thickness in the present embodiment is not particularly limited.

[0073] The fiber thickness in the present embodiment can be, for example, 0.5 dtex or more and 50 dtex or less.

[0074] The fiber sheet 21 can also contain two or more kinds of fibers that differ in thickness or material.

[0075] The fiber sheet 21 can be composed of staple fibers or continuous fibers, and can also use both staple fibers and continuous fibers.

[0076] The fiber sheet 21 can be composed of spun yarn, can be composed of filament yarn, or can use both spun yarn and filament yarn.

[0077] The filament yarn can also be a bulky processed yarn such as a crimped yarn, etc.

[0078] The filament yarn may be single-filament rayon or multi-filament rayon.

[0079] The multi-filament rayon may be an aligned yarn obtained by simply aligning filaments, or may be a twisted yarn obtained by twisting.

[0080] The twisted yarn may be a lightly twisted yarn with a twist number of less than 500 times / m, a moderately twisted yarn with a twist number of 500 times / m or more and less than 1000 times / m, a strongly twisted yarn with a twist number of 1000 times / m or more and less than 2500 times / m, or an ultra-strongly twisted yarn with a twist number of 2500 times / m or more.

[0081] When the spun yarn or the filament yarn is used in the present embodiment, the total fineness thereof is not particularly limited.

[0082] The total fineness may be, for example, 100 dtex or more and 10,000 dtex or less.

[0083] like Figure 2 、 Figure 3 As shown, the fiber sheet 21 of this embodiment has a stacked structure of at least three layers, and the three-layer stacked structure includes a surface layer 211 constituting the outer surface of the shoe 1, an inner layer 213 arranged on the inner side of the surface layer 211, and an intermediate layer 212 arranged between the surface layer 211 and the inner layer 213.

[0084] The surface layer 211 , the inner layer 213 , and the intermediate layer 212 are respectively composed of the aforementioned fibers.

[0085] The surface layer 211 , the middle layer 212 , and the inner layer 213 may have different thicknesses, fiber densities, etc., and may be composed of different fibers.

[0086] For example, the fiber sheet 21 of this embodiment may be configured such that one of the surface layer 211 , the intermediate layer 212 , and the inner layer 213 is made of multi-filament rayon or spun yarn, and the other is made of single-filament rayon.

[0087] The fiber sheet 21 of this embodiment may have a thickness of, for example, 1 mm to 8 mm.

[0088] The surface layer 211 , the intermediate layer 212 , and the inner layer 213 may each be generally formed to have a thickness of not less than 0.5 mm and not more than 4 mm.

[0089] In the fiber sheet 21 of this embodiment, the surface layer 211 has an area substantially the same as that of the inner layer 213 , but the middle layer 212 has an area smaller than that of the surface layer 211 and the inner layer 213 .

[0090] That is, in the fiber sheet 21 of the present embodiment, the intermediate layer 212 is provided only in a partial region.

[0091] The fiber sheet 21 of the present embodiment has a connection portion 21a in which the surface layer 211 and the inner layer 213 are connected by the intermediate layer 212, and a non-connection portion 21b in which the surface layer 211 and the inner layer 213 are not connected because the intermediate layer 212 is not provided.

[0092] In the non-connection portion 21b of the present embodiment, a distance equivalent to the thickness of the intermediate layer 212 is provided between the surface layer 211 and the inner layer 213.

[0093] That is, in the non-connection portion 21b, a space portion 210 is formed inside.

[0094] In the fiber sheet 21 of the present embodiment, the connection portion 21a and the non-connection portion 21b are respectively provided in a plurality of regions.

[0095] One of the connection portions 21a is continuously extended over the entire range of the fiber sheet 21, and a plurality of non-connection portions 21b surrounded by this connection portion 21a are dispersed in the fiber sheet 21.

[0096] In the present embodiment, a plurality of small connection portions 21a can also be dispersed inside at least one of the non-connection portions 21b.

[0097] In the fiber sheet 21 of the present embodiment, higher strength is exerted in the connection portion 21a.

[0098] In the fiber sheet 21 of the present embodiment, excellent softness is exerted in the non-connection portion 21b.

[0099] The non-connection portion 21b also has excellent air permeability.

[0100] The fiber sheet 21 of the present embodiment has a relatively large non-connection portion 21b in each of the forefoot portion 11, the midfoot portion 12, and the rearfoot portion 13 of the shoe 1.

[0101] Further, the forefoot portion 11, the midfoot portion 12, and the rearfoot portion 13 correspond to each portion when the shoe 1 is divided into three in the length direction X into a region in which a palm portion is formed and regions before and after the same.

[0102] That is, the shoe 1 of the present embodiment has the forefoot portion 11, the midfoot portion 12, and the rearfoot portion 13 in this order from the front to the rear.

[0103] The non-connection portion 21b can accommodate other components different from the fiber sheet 21 as described later.

[0104] In the shoe upper 2 of this embodiment, the strength and design can be adjusted by such other components.

[0105] On the other hand, in order to simplify the manufacturing process of the shoe and reduce the weight of the shoe, it is preferable to achieve desired properties by the fiber sheet 21 without relying on such components.

[0106] Specifically, in the shoe upper 2 of this embodiment, preferably, in the rear foot portion 13 , the area ratio of the connecting portion 21 a to the non-connecting portion 21 b is large.

[0107] In a typical shoe upper, it is desired to exhibit excellent rigidity in the rear foot portion.

[0108] According to the above preferred embodiment, such requirements can be met.

[0109] In the midfoot portion 12 , the area of ​​the connection portion having a larger dimension in the vertical direction of the shoe than in the front-back direction is preferably larger than the area of ​​the non-connection portion having a larger dimension in the front-back direction than in the vertical direction.

[0110] Generally, in a shoe upper, it is desired that a high stress be exerted in the midfoot portion against elongation in the up-down direction.

[0111] According to the above preferred embodiment, such requirements can be met.

[0112] Preferably, a plurality of the connecting portions 21 a having a larger size in the up-down direction are formed on at least one of the inner foot side and the outer foot side of the shoe 1 .

[0113] In particular, the shoe 1 of this embodiment is preferably in a state where the connecting portion 21 a and the non-connecting portion 21 b having a shape elongated in the vertical direction are alternately arranged from the toe side to the heel side of the midfoot portion 12 .

[0114] In other words, the upper 2 of this embodiment is preferably arranged in a group or array from the toe side to the heel side, with the connecting portion 21a having a shape that is long in the vertical direction and the non-connecting portion 21b having a shape that is long in the vertical direction adjacent to each other.

[0115] In the front foot portion 11 of this embodiment, preferably, the area ratio of the non-connecting portion 21 b to the connecting portion 21 a is higher than that of both the mid-foot portion 12 and the rear foot portion 13 .

[0116] In a typical shoe upper, higher air permeability is required in the forefoot portion.

[0117] According to the above-described preferred embodiment, the above-described requirements can be satisfied.

[0118] In particular, the shoe 1 of the present embodiment is preferably such that, in the forefoot portion 11, the area ratio of the non-connection portion 21b with respect to the total area of the connection portion 21a and the non-connection portion 21b is 25% or more.

[0119] The area ratio is more preferably 30% or more, further preferably 35% or more, and particularly preferably 40% or more.

[0120] However, if the non-connection portion 21b is excessively formed, it is difficult to exhibit sufficient strength, and thus the area ratio is preferably 95% or less.

[0121] The surface layer 211 of the present embodiment is composed of the fiber described above.

[0122] The fiber can constitute the surface layer 211 in the state of a yarn.

[0123] The surface layer 211 of the present embodiment is composed of the fiber, and thus a gap for light transmission is formed between the fibers or between the yarns.

[0124] That is, in the upper 2 of the present embodiment, the state of the intermediate layer 212 can be confirmed from the outside through the gap of the surface layer 211.

[0125] The non-connection portion 21b does not have the intermediate layer 212 provided therein, and thus, when viewed from the surface side, it is in a state in which the inner layer 213 can be visually confirmed through the surface layer 211.

[0126] Thus, the fiber sheet 21 of the present embodiment is in a state in which the visual effects of the connection portion 21a and the non-connection portion 21b are different, and can freely express characters, figures, and the like by changing the shapes thereof.

[0127] The larger the size of the gap formed in the surface layer 211 is, the easier it is to confirm the state of the intermediate layer 212 in the connection portion 21a and the state of the inner layer 213 in the non-connection portion 21b.

[0128] Thus, the surface layer 211 is preferably composed of a yarn having a certain degree of thickness.

[0129] The fiber sheet 21 of the present embodiment is such that the surface layer 211 is composed of a surface yarn 2111.

[0130] In terms of the easiness of confirming the state of the inside, it is preferable that at least a part of the surface layer 211 be composed of a single-fiber rayon.

[0131] That is, in the present embodiment, preferably, a part or all of the surface yarn 2111 is a single fiber rayon.

[0132] In order to more significantly exert the above-mentioned effects, it is preferable that the proportion of the single fiber rayon in the surface yarn 2111 be 10 mass% or more, more preferably 25 mass% or more, and further preferably 50 mass% or more.

[0133] In order to more easily confirm the state of the intermediate layer 212 and the inner layer 213, the single fiber rayon is preferably colorless and transparent.

[0134] That is, the single fiber rayon is preferably made of a natural color synthetic resin that does not contain a pigment or a filler, and is preferably a polyester monofilament, a polyamide monofilament, a fluorocarbon monofilament, or the like.

[0135] In order to more easily confirm the state of the intermediate layer 212 and the inner layer 213, for example, a through-hole 211h as shown in Figs. 11A and 11B can also be provided in the fiber sheet 21 of the present embodiment. Figure 4 、 Figure 5

[0136] That is, in the fiber sheet 21 of the present embodiment, a through-hole 211h that penetrates the surface layer 211 can also be formed in one or both of the connection portion 21a and the non-connection portion 21b.

[0137] The fiber sheet 21 of the present embodiment is preferably a single woven fabric, and portions that become the surface layer 211, the intermediate layer 212, and the inner layer 213 are preferably provided in the thickness direction of the woven fabric.

[0138] The fiber sheet 21 is more preferably a warp-knitted fabric.

[0139] In the warp-knitted fabric, generally, the surface layer 211 is constituted by a surface yarn 2111, the inner layer 213 is constituted by an inner yarn 2131, and the intermediate layer 212 is constituted by an intermediate yarn 2121 that is knitted into both the surface yarn 2111 and the inner yarn 2131, so it is easy to form the intermediate layer 212 to be relatively thick.

[0140] Therefore, in the warp-knitted fabric, it is easy to form a relatively large space portion 210 between the surface layer 211 and the inner layer 213.

[0141] In the warp-knitted fabric, it is also easy to form the through-hole 211h and the like.

[0142] In the fiber sheet 21 of the present embodiment, other components different from the fiber sheet 21 can also be accommodated in the space portion 210 provided between the surface layer 211 and the inner layer 213.

[0143] ​The member can also be housed in the space portion 210 in a state of being bonded to one or both of the surface layer 211 and the inner layer 213.

[0144] The member can also be housed in the space portion 210 in a state of not being bonded to the fiber sheet 21 at all.

[0145] In this case, in order to make the housed member movable inside the space portion 210, the member can also be formed to be smaller in size (area) than the non-connection portion 21b.

[0146] The size (area) of the member can be, for example, 80% or less of the area of the non-connection portion 21b.

[0147] The size of the member can also be 50% or less of the area of the non-connection portion 21b.

[0148] The space portion 210 can also house a plurality of members.

[0149] In the case where a plurality of non-connection portions 21b (space portions 210) including a first non-connection portion 21b (first space portion 210) and a second non-connection portion 21b (second space portion 210) are formed in the fiber sheet 21, a first member housed in the first space portion 210 and a second member housed in the second space portion 210 can be the same or different in raw material and size.

[0150] As the member housed in the space portion 210, for example, as shown in Figure 6 the member can also be a hollow balloon P1.

[0151] If a hollow balloon P1 composed of a transparent film is housed in the space portion 210, the difference in light transmittance between the connection portion 21a and the non-connection portion 21b becomes more conspicuous.

[0152] A gas or a liquid can be housed inside the balloon P1, and a powder can also be housed.

[0153] The fiber sheet 21 can also be such that the balloon P1 and the fiber sheet 21 are different in color, thereby making the appearance of the connection portion 21a and the non-connection portion 21b more different.

[0154] In this case, the balloon P1 can be colored, or the balloon P1 can be transparent and house a colored liquid inside.

[0155] The balloon P1 can also be formed of a raw material having excellent light reflectance, such as an aluminum layer film.

[0156] That is, the difference in design between the air bag P1 and the fiber sheet 21 can be expressed by their colors or by the difference in light reflectivity (luster).

[0157] The through hole 211h is formed in the surface layer 211 of the non-connection portion 21b in which the air bag P1 is housed, whereby the air bag P1, which is different in design from the fiber sheet 21, can be directly observed from the outside of the upper 2 through the through hole 211h.

[0158] If the air bag P1 is made of rubber, the volume of the member housed in the space portion 210 can be changed.

[0159] In the case where the member capable of changing the volume is housed in the space portion 210, for example, as shown in Figure 7 the thickness of the air bag P1 can be formed to be equal to or greater than the thickness of the intermediate layer 212, thereby causing the non-connection portion 21b to expand outward.

[0160] As the member housed in the space portion 210, for example, as shown in Figure 8 the sheet member P2 having a thickness smaller than the thickness of the intermediate layer 212 can be housed.

[0161] The sheet member P2 can be provided with a pattern or characters, etc.

[0162] In this case, if a design different from that of the fiber sheet 21 is applied to the sheet member P2, the difference in appearance between the connection portion 21a and the non-connection portion 21b becomes more apparent.

[0163] Further, in the non-connection portion 21b in which the sheet member P2 is housed on the inside, a through hole 211h can be further provided in the surface layer 211 thereof.

[0164] As shown in Figure 9 In the space portion 210, as the member, for example, a solidified product P3 obtained by solidifying a liquid can be housed.

[0165] In this case, if the liquid capable of being solidified is introduced into the space portion 210 and then solidified, a part of the liquid is infiltrated into the surface layer 211 and the inner layer 213 and solidified, and the solidified product P3 can be securely held.

[0166] The liquid can further contain a powder having light reflectivity such as a metal flake.

[0167] In the case where the solidified product is transparent, the light reflectivity of the powder inside the solidified product can be effectively utilized to cause the difference in appearance between the connection portion 21a and the non-connection portion 21b.

[0168] The liquid can also be a liquid that is foamed like a raw liquid of a polyurethane foam.

[0169] That is, the cured product P3 can also be a foam.

[0170] In this case, the non-connection portion 21b can be brought to a state of swelling outward by the cured product P3 (foam).

[0171] As with the air bag P1 and the sheet member P2, the cured product P3 can be utilized in the design of the upper 2 by making the design of the cured product P3 different from that of the fiber sheet 21.

[0172] The cured product P3 is also effective for reinforcing the upper 2.

[0173] For example, the non-connection portion 21b is provided at the rear foot portion 13, is arranged so as to cover the heel of the foot, and the cured product P3 is provided in the non-connection portion 21b, and the cured product P3 can function as a heel counter.

[0174] In this case, the non-connection portion 21b is preferably provided so as to cover from the medial side, the lateral side, and the rear of the heel.

[0175] The non-connection portion 21b is preferably provided so as to be connected to the sole 3.

[0176] The member housed in the space portion 210 can also be a member other than the above-described examples.

[0177] For example, a fiber material such as yarn or cotton can also be filled in the space portion 210.

[0178] If the fiber material is excessively filled with respect to the volume of the space portion 210 in the natural state, as with the air bag P1, the non-connection portion 21b can be caused to swell outward.

[0179] In addition, the fiber material housed in the space portion 210 can also be dyed in various colors.

[0180] The fiber sheet 21 of the present embodiment can also be colored or have a pattern drawn on the surface of the inner layer 213 facing the space portion 210 instead of providing such a member in the structure of the space portion 210.

[0181] In conventional uppers, a leather sheet that is shaped into a prescribed shape by being processed in an external shape is attached to a fiber sheet in order to draw a pattern, characters, or the like.

[0182] In the shoe 1 of the present embodiment, by forming the connection portions 21a and the non-connection portions 21b in a specific shape, it is possible to draw characters, figures, and the like on the fiber sheet itself used to form the upper 2, and thus, compared to conventional shoes, it is possible to reduce the amount of use of leather sheets and the like.

[0183] The leather sheet, which is a component of the upper of a shoe, is generally cut out from a raw sheet having a size that allows several to several tens of leather sheets larger than the leather sheet in area to be cut out.

[0184] In the case of producing a plurality of shoes of different designs, raw sheets of different colors and materials are prepared, and leather sheets of a prescribed shape are cut out from each of these raw sheets.

[0185] The shoe 1 of the present embodiment can easily express various figures and characters on the upper without using a leather sheet or the like, and thus, compared to conventional shoes, it is possible to reduce the time taken to manufacture.

[0186] In addition, the shoe 1 of the present embodiment can suppress the situation in which a raw sheet remaining after cutting out a leather sheet becomes waste material at the time of manufacture, and is thus excellent from the viewpoint of resource saving.

[0187] Furthermore, the above described examples show only a part of the present application with respect to the upper and the shoe, but the present application is not limited to the above described examples.

[0188] For example, in the above described examples, a case in which the fiber sheet of the upper has three layers of a surface layer, an intermediate layer, and an inner layer is exemplified, but the upper of the present application can have other layers further inside the inner layer.

[0189] In addition, with respect to matters other than this, the present application can be additionally changed in various ways in the above described examples.

[0190] That is, in the present application, within a range in which the effect is not significantly impaired, matters known in the art can be widely adopted with respect to the shoe and the upper.
