Prior patent literature
Patent document 1: international publication No. WO2016/033051
The upper is required to have not only predetermined properties in terms of functions such as strength and air permeability, but also important in terms of its appearance, and may have a member such as a leather sheet different from the fiber sheet.
For example, in the upper of a shoe, a figure or a letter is drawn on the surface by a leather sheet sewn to a fiber sheet.
Leather pieces used for expressing specific figures, characters, and the like on the appearance of shoes are generally produced by punching a large piece of raw material with a cutting die by a punching method.
The leather sheet is not limited to a shape that can be punched out from a raw material sheet without waste.
Therefore, the raw material sheet is not effectively utilized as a shoe member and the ratio of scrap portions is not sufficiently low.
In addition, the use of leather pieces for this purpose in shoes has been a factor of increasing the number of steps in the shoe manufacturing process.
Therefore, when shoes of various designs are manufactured, the manufacturing process may become complicated, and a large amount of waste may be discharged.

As shown in fig. 2 and 3, the fiber sheet 21 of the present embodiment has a three-layer laminated structure including a surface layer 211 constituting an outer surface of the shoe 1, an inner layer 213 disposed inside the surface layer 211, and an intermediate layer 212 provided between the surface layer 211 and the inner layer 213.
The surface layer 211, the inner layer 213, and the intermediate layer 212 are each made of the above-described fibers.
The surface layer 211, the intermediate layer 212, and the inner layer 213 may have different thicknesses, fiber densities, and the like, or may be formed of different fibers.
For example, in the fiber sheet 21 of the present embodiment, one of the surface layer 211, the intermediate layer 212, and the inner layer 213 may be formed of a multifilament or spun yarn, and the other may be formed of a monofilament yarn.
The fiber sheet 21 of the present embodiment may have a thickness of 1mm to 8mm, for example.
The surface layer 211, the intermediate layer 212, and the inner layer 213 may be formed to have a thickness of 0.5mm to 4mm, respectively.
In the fiber sheet 21 of the present embodiment, the surface layer 211 has substantially the same area as the inner layer 213, but the intermediate layer 212 has a smaller area than the surface layer 211 and the inner layer 213.
That is, in the fiber sheet 21 of the present embodiment, the intermediate layer 212 is provided only in a part.
The fiber sheet 21 of the present embodiment includes: a connection portion 21a connecting the surface layer 211 and the inner layer 213 via the intermediate layer 212; the intermediate layer 212 is not provided so that the skin layer 211 and the inner layer 213 are not connected to the non-connecting portion 21 b.
In the non-connecting portion 21b of the present embodiment, a distance corresponding to the thickness of the intermediate layer 212 is provided between the surface layer 211 and the inner layer 213.
That is, a space portion 210 is formed inside the non-connection portion 21 b.
In the fiber sheet 21 of the present embodiment, the connecting portions 21a and the non-connecting portions 21b are provided at a plurality of positions in a dispersed manner.
One of the connecting portions 21a continuously expands over the entire fiber sheet 21, and a plurality of the non-connecting portions 21b surrounded by the connecting portions 21a are dispersed in the fiber sheet 21.
In the present embodiment, a plurality of small connecting portions 21a may be dispersed inside at least one of the non-connecting portions 21 b.
In the fiber sheet 21 of the present embodiment, the connecting portion 21a exhibits high strength.
In the fiber sheet 21 of the present embodiment, excellent flexibility is exhibited in the non-connecting portion 21 b.
The non-connecting portion 21b also has excellent air permeability.
The fiber sheet 21 of the present embodiment has the non-connecting portions 21b having relatively large areas in the forefoot portion 11, the midfoot portion 12, and the hindfoot portion 13 of the shoe 1.
The forefoot portion 11, the midfoot portion 12, and the rearfoot portion 13 correspond to respective portions of the shoe 1 divided into a section in which the palm portion is formed and a section in front of and behind the section in the longitudinal direction X.
That is, the shoe 1 of the present embodiment includes the forefoot portion 11, the midfoot portion 12, and the rearfoot portion 13 in this order from the front to the rear.
The non-connecting portion 21b can accommodate components other than the fiber sheet 21 as described later.
In the upper 2 of the present embodiment, the strength and design can be adjusted by such other members.
On the other hand, when the manufacturing process of the shoe is simplified and the shoe is made lightweight, it is preferable that the fiber sheet 21 exhibits desired characteristics without depending on such members.
Specifically, in the upper 2 of the present embodiment, it is preferable that the area ratio of the connecting portion 21a to the non-connecting portion 21b is large in the rear foot portion 13.
In a general shoe upper, it is desired that the rear foot portion exhibits excellent rigidity.
According to the above preferred embodiment, such a requirement can be satisfied.
In the midfoot portion 12, it is preferable that the area of the connecting portion, which is larger in the vertical direction of the shoe than in the longitudinal direction of the shoe, is larger than the area of the non-connecting portion, which is larger in the longitudinal direction than in the vertical direction.
In general, in the upper of a shoe, it is desired that a high stress can be exerted on the midfoot portion against the elongation in the vertical direction.
According to the above preferred embodiment, such a requirement can be satisfied.
Preferably, a plurality of the connecting portions 21a having a large size in the vertical direction are formed on at least one of the inner leg side and the outer leg side of the shoe 1.
In particular, in the shoe 1 of the present embodiment, it is preferable that the connecting portions 21a and the non-connecting portions 21b, which are elongated in the vertical direction, are alternately arranged from the toe side to the heel side of the midfoot portion 12.
In other words, in the upper 2 of the present embodiment, it is preferable that the connecting portions 21a having a shape elongated long in the vertical direction and the non-connecting portions 21b having a shape elongated long in the vertical direction are arranged in a row or a plurality of rows from the toe side to the heel side in a state adjacent to each other.
In the front leg 11 of the present embodiment, the non-connection portion 21b preferably has a higher area ratio to the connection portion 21a than both the middle leg 12 and the rear leg 13.
In the upper of a typical shoe, high air permeability is required in the forefoot.
According to the above preferred embodiment, such a requirement can be satisfied.
In particular, in the shoe 1 of the present embodiment, it is preferable that the area ratio of the non-connecting portion 21b to the total area of the connecting portion 21a and the non-connecting portion 21b in the forefoot portion 11 is 25% or more.
The area ratio is more preferably 30% or more, still more preferably 35% or more, and particularly preferably 40% or more.
However, since it is difficult to exhibit sufficient strength when the non-connecting portion 21b is excessively formed, the area ratio is preferably 95% or less.
The surface layer 211 of the present embodiment is made of the fibers.
The fibers may constitute the surface layer 211 in a state of yarn.
Since the surface layer 211 in the present embodiment is made of fibers, gaps through which light passes are formed between fibers or between yarns.
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 in the surface layer 211.
Since the non-connecting portion 21b is not provided with the intermediate layer 212, the inner layer 213 can be easily visually confirmed by the surface layer 211 when viewed from the front side.
Therefore, in the fiber sheet 21 of the present embodiment, the connecting portion 21a and the non-connecting portion 21b have different visual effects, and characters, figures, and the like can be freely expressed by changing the shapes thereof.
The larger the size of the gap formed in the surface layer 211, the easier it is to check 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 21 b.
Therefore, the surface layer 211 is preferably made of a yarn having a certain degree of thickness.
In the fiber sheet 21 of the present embodiment, the surface layer 211 is formed of the surface yarn 2111.
In order to facilitate confirmation of the inside state, it is preferable that at least a part of the surface layer 211 is made of monofilament rayon.
That is, in the present embodiment, it is preferable that a part or all of the top yarn 2111 be monofilament rayon.
In order to more significantly exhibit the above-described effects, the proportion of the monofilament rayon in the cover yarn 2111 is preferably 10% by mass or more, more preferably 25% by mass or more, and still more preferably 50% by mass or more.
The monofilament rayon is preferably colorless and transparent in order to facilitate confirmation of the state of the intermediate layer 212 and the inner layer 213.
That is, the monofilament rayon is preferably made of natural colored synthetic resin containing no pigment or filler, and is preferably polyester monofilament, polyamide monofilament, fluorocarbon monofilament, or the like.
In order to make it easier to check the state of the intermediate layer 212 and the inner layer 213, for example, through holes 211h as shown in fig. 4 and 5 may be provided in the fiber sheet 21 of the present embodiment.
That is, in the fiber sheet 21 of the present embodiment, the through-holes 211h penetrating the surface layer 211 may be formed in one or both of the connection portion 21a and the non-connection portion 21 b.
The fiber sheet 21 of the present embodiment is preferably a single woven fabric, and is preferably provided in the thickness direction of the woven fabric at the positions of the surface layer 211, the intermediate layer 212, and the inner layer 213.
The fiber sheet 21 is more preferably a warp-knitted fabric.
In the warp-knitted fabric, the surface layer 211 is generally composed of the top yarn 2111, the inner layer 213 is composed of the back yarn 2131, and the intermediate layer 212 is composed of the intermediate yarn 2121 knitted into both the top yarn 2111 and the back yarn 2131, and therefore the intermediate layer 212 can be easily formed to be relatively thick.
Therefore, in the warp-knitted fabric, a relatively large space portion 210 is easily formed between the surface layer 211 and the inner layer 213.
In the warp-knitted fabric, the through-holes 211h and the like can be easily formed.
In the fiber sheet 21 of the present embodiment, another member different from the fiber sheet 21 may be accommodated in the space 210 provided between the surface layer 211 and the inner layer 213.
The member may be accommodated in the space 210 in a state of being bonded to one or both of the surface layer 211 and the inner layer 213.
The member may be housed in the space portion 210 in a state where the member is not bonded to the fiber sheet 21 at all.
In this case, the component may be formed to have an area smaller than that of the non-connection portion 21b so that the component can be moved inside the space portion 210.
The size (area) of the member may be, for example, 80% or less of the area of the non-connecting portion 21 b.
The size of the member may be 50% or less of the area of the non-connecting portion 21 b.
The space portion 210 may also accommodate a plurality of components.
When a plurality of non-connecting portions 21b (space portions 210) including the first non-connecting portion 21b (first space portion 210) and the second non-connecting portion 21b (second space portion 210) are formed in the fiber sheet 21, the first member housed in the first space portion 210 and the second member housed in the second space portion 210 may be made of the same material or different materials and sizes.
As the member housed in the space portion 210, for example, as shown in fig. 6, a hollow airbag P1 may be used.
When the hollow airbag P1 made of a transparent thin film is accommodated in the space portion 210, the difference in light transmittance between the connecting portion 21a and the non-connecting portion 21b becomes more significant.
The air bag P1 may contain a gas or a liquid or may contain a powder.
The fiber sheet 21 may be formed such that the airbag P1 and the fiber sheet 21 are different in color, thereby making the difference in appearance between the connected portion 21a and the non-connected portion 21b more noticeable.
In this case, the airbag P1 may be dyed, or the airbag P1 may be transparent and contain a dyed liquid therein.
The air bag P1 may be formed of a material having excellent light reflectivity, such as an aluminum layer film.
That is, the difference in design between the air bag P1 and the fiber sheet 21 can be expressed by the color thereof or the difference in light reflectivity (gloss).
By forming the through-hole 211h in the surface layer 211 that accommodates the non-connecting portion 21b of the airbag P1, the airbag P1 having a design different from that of the fabric sheet 21 can be observed directly through the through-hole 211h from the outside of the upper 2.
When the airbag P1 is made of rubber, the volume of the member accommodated in the space 210 can be changed.
In the case where a member capable of volume change is accommodated in the space portion 210, for example, as shown in fig. 7, the airbag P1 can be formed to have a thickness equal to or greater than that of the intermediate layer 212, thereby expanding the non-connecting portion 21b outward.
As the member accommodated in the space portion 210, for example, as shown in fig. 8, a sheet member P2 having a thickness smaller than that of the intermediate layer 212 may be used.
The sheet member P2 may be painted with graphics, characters, or the like.
In this case, if the sheet member P2 is designed differently from the fiber sheet 21, the difference in appearance between the connecting portion 21a and the non-connecting portion 21b becomes more clear.
In the non-joined portion 21b in which the sheet member P2 is housed, a through hole 211h may be provided in the surface layer 211.
As shown in fig. 9, the space 210 may contain, as the component, for example, a cured product P3 obtained by curing a liquid.
In this case, when a curable liquid is introduced into the space 210 and then the liquid is cured, a part of the liquid wets the surface layer 211 and the inner layer 213 and is cured, and the cured product P3 can be firmly held.
The liquid may contain a light-reflective powder such as a metal flake.
When the cured product is transparent, the light reflectivity of the powder inside the cured product can be effectively utilized to make the appearance of the connecting portion 21a different from that of the non-connecting portion 21 b.
The liquid may be a foamable liquid such as a stock solution of polyurethane foam.
That is, the cured product P3 may be a foam.
In this case, the non-connecting portion 21b can be expanded outward by the cured product P3 (foam).
Like the airbag P1 and the sheet member P2, the cured product P3 can be used for designing the upper 2 by making the design different from the fiber sheet 21.
The cured product P3 is also effective for reinforcing the upper 2.
For example, by providing the non-connecting portion 21b in the rear leg portion 13, disposing the non-connecting portion 21b so as to cover the heel of the foot, and providing the cured product P3 in the non-connecting portion 21b, the cured product P3 can function as a heel counter (heel counter).
In this case, the non-connecting portion 21b is preferably provided so as to cover the heel from three directions, i.e., the inner foot side, the outer foot side, and the rear side.
The non-connecting portion 21b is preferably provided so as to be connected to the sole 3.
The member accommodated in the space portion 210 may be other than those exemplified above.
For example, the space portion 210 may be filled with a fiber material such as yarn or cotton.
When the fibrous material is excessively filled with respect to the volume of the space portion 210 in a natural state, the non-connecting portion 21b can be expanded outward, similarly to the airbag P1.
In addition, the fiber material received in the space part 210 may be dyed various colors.
In the fiber sheet 21 of the present embodiment, instead of providing such a member in the space portion 210, the surface of the inner layer 213 facing the space portion 210 may be colored, painted, or the like.
In a conventional upper, a leather sheet having an outer shape formed into a predetermined shape is attached to a fabric sheet in order to draw figures, characters, and the like.
In the shoe 1 of the present embodiment, since the connecting portion 21a and the non-connecting portion 21b are formed in a specific shape, characters, figures, and the like can be drawn on the fiber sheet itself for forming the upper 2, and therefore, the amount of leather sheets and the like used can be reduced compared to conventional shoes.
A leather sheet, which is a component of a shoe upper, is generally cut from a raw material sheet having a size capable of cutting several to several tens of leather sheets having an area larger than that of the leather sheet.
When a plurality of types of shoes with different designs are manufactured, raw material pieces with different colors and materials are prepared, and leather pieces with a predetermined shape are cut out from the raw material pieces.
The shoe 1 of the present embodiment can easily show various figures and characters on the upper surface without using a leather sheet or the like, and thus it does not take a lot of time and effort to manufacture compared with conventional shoes.
The shoe 1 of the present embodiment is also excellent from the viewpoint of resource saving because it can suppress the raw material pieces left after cutting the leather pieces during manufacturing from becoming waste.
The above description shows an example of a part of the present invention relating to an upper and a shoe, but the present invention is not limited to the above example.
For example, although the case where the fiber sheets included in the upper are three layers, i.e., the surface layer, the intermediate layer, and the inner layer, the upper of the present invention may include another layer on the inner side of the inner layer.
In addition to the above matters, the present invention can be modified in various ways by adding various modifications to the above examples.
That is, in the present invention, conventionally known technical matters can be widely adopted for shoes and shoe uppers within a range that does not significantly impair the effect.
