Detailed description of the invention

Below with reference to Figure 1A, Figure 1B and Fig. 1 C, article of footwear 10 comprises the top 105 engaging (such as, being arranged on footwear sole construction 110) with footwear sole construction 110 according to an embodiment of the invention.Article of footwear 10 defines several regions corresponding with the various piece of pin.Specifically, footwear 10 are limited with: footwear region, rear portion 115, and it is roughly corresponding with heel (such as, comprising the pin back segment of heel); Middle footwear region 120, it is arranged in the front of Background Region and roughly corresponding with pin stage casing (such as, the arch instep of pin and sole of the foot ball region); And anterior footwear region 125, it is arranged in the front of zone line and roughly corresponding with pin leading portion (such as, the toe of pin).Article of footwear 10 can also comprise securing member 127 (such as, shoestring) and rear side (heelcounter) 129 (will discuss in more detail below).

Top 105 comprises heel portion 130, outside portion 135, inside portion 140, instep portion (instep) 145 and toe case or case 150.Heel portion 130 forms the rear section on top 105 and the heel be substantially configured to along pin extends.Outside portion 135 stride across footwear 10 longitudinal length and along pin outside and extend.Similarly, inside portion 140 extends along the longitudinal length of footwear 10, thus inside portion 140 along pin inner side and extend.Instep portion 145 between outside portion and inside portion, across pin instep and consist essentially of flap 147.Finally, toe case 150 defines the front area on top 105 and is configured to hold the toe of pin.

Top 105 defines the cavity receiving pin.Specifically, heel portion 130, outside portion 135, inside portion 140, instep portion 145 and toe case 150 are worked in coordination with and are defined inner chamber, and pin is inserted in this inner chamber by entrance or footwear neck 155.Footwear neck 155 may be made in the webbing having and such as applied by adhesive.In one embodiment, around inner edge material webs being applied to footwear neck 155, to allow the edge making footwear neck when adhesion without adhesiver (binding), thus reduce wear and/or contribute to making footwear lead the skin attaching user.Material can be elastomeric material and/or sticky polymers, such as, but not limited to: polyurethane, silicones, nylon and polyester.

In the embodiment shown in Figure 2, top 105 is formed by two parts, wherein Part I or plane (planum) part 205 are carried on the back (dorsum) part 210 by seamless combination parts 215 with Part II or footwear and are engaged (such as, connecting).With reference to figure 3, the flat support 315B that the basic covering heel of pin and the planar section 205 of plane domain comprise heel cup 315A and extend forward from heel cup.Heel cup 315A be configured to around the outside of heel bone (calcaneum), the self supporting structure of inner side and bottom side.As shown in the figure, heel cup 315A limited by the wall 325 with the Outboard Sections 330A ending at front outsides edge 335A and the inboard portion 330B ending at front inner edge 335B.Vertical wall 325, at its lower end bend forward, is transitioned into flat support 315B, and vertically wall and flat support are worked in coordination with and defined bending heel recess or heel cup 340.In another embodiment, vertical wall upwards can extend along with it (direction along footwear neck 155) and curve inwardly (towards pin).

Flat support 315B extends forward from bending heel recess 340, to limit pin stage casing supporting zone 345A and pin leading portion supporting zone 345B.Pin stage casing supporting zone 345A can be the structure substantially taken the shape of the letter U, and defines diapire 350; Substantially vertical outside lug or wall 355A, it ends at exterior front edge 360A; And substantially vertical inner side lug or wall 355B, it ends at interior front edge 360B.Pin leading portion supporting zone 345B defines the parts being configured to stride across the sole of the foot ball of pin and the substantially flat of toe.

The heel cup 340 of planar section 205 is seamless.Conventional footwear comprise seam (such as, welded side seam or make seam) usually in heel cup.Such as, conventional heel cup comprises the longitudinal seam of the connecting portion between the vertical seam along the connecting portion between two heel half portion (inner side half portion and lateral half) and the two half-unit along foot pad.In contrast, the heel portion 130 of the article of footwear 10 discussed in this article does not comprise seam.As an alternative, heel portion 130 is the single structures being formed as defining seamless, single heel cup 340.In another embodiment, whole planar section 205 is seamless, and heel cup 315A and flat support 315B forms single and/or single structure.

In addition, top 105 is without socks formula (sockless) according to an embodiment of the invention, defines the shell surrounding pin.Conventional footwear generally include has attachment (such as making) in the top of the open bottom of sole.Then, material layer is set to the inside of footwear to form the bed course between sole and pin, the joint between top and footwear sole construction stashes by this bed course.In contrast, according to an embodiment of the invention " the interior end " of article of footwear 10 be effectively integrated in top 105, thus heel portion and the interior end, form single structure (internal layer such as, formed in the fabric laminate on top 105 is used as socks or shoe-pad).Thus, do not need other socks or the interior end.

With reference to figure 4, the basic footwear back portion 210 covering the instep of pin comprises cardinal extremity part 405A and distal portions 405B.Cardinal extremity part 405A essentially defines the region, outside portion 135 on top 105, region, inside portion 140, region, instep portion 145.As shown in the figure, the cardinal extremity part 405A of footwear back portion 210 comprises the outer flap 410A and inner flap 410B that are separated by central opening 415.Outer flap 410A is the parts of substantially flat, and comprises multiple fin of laterally inwardly extending or ring portion 420A to 420D (towards central opening 415).Ring portion comprises two fabric components, and these two fabric components are oriented to parallel to each other and are fixed to one another (connection) longitudinally-spaced two positions.Utilize this structure, each ring portion 420A to 420D defines the passage that can pass for securing member 127, thus form the tie point for securing member (see Figure 1B).But, should be appreciated that and other fastening connection piece of eyelet/grommet 422 grade can be used to fix securing member 127.

Cardinal extremity part 405A also comprises flap connector 425, and flap 147 can be attached (such as, by heat conduction adhesive tape) on flap connector 425.Flap 147 can be formed by the material similar with top, and identical method (will discuss in more detail below) can be used to be formed.Specifically, flap 147 can comprise such three-dimensional macro structure: the lateral dimension bending (such as, bending along its width) of flap, thus flap follows the profile of instep 145.In addition, flap 147 can be constructed so that flap along its transverse direction and/or longitudinal edge convergent, make the middle section of flap thicker and towards flap edge gradually thinning (such as, the thickness at edge can be 1/16 of the thickness of middle section).This can realize as the layer of fabric laminate by being compressed to largely by the fabric laminate of flap along edge and/or using the froth bed of cutting.

As selection, flap 147 can be formed by different materials, and these materials are including, but not limited to fabric, net etc.

In one embodiment, one or more parts 205,210 on top 105 can comprise the perforation allowing fluid (such as, air and/or water) to extend there through.In other examples, top 105 do not comprise perforation with reduce or anti-fluid flow through top.

Although do not describe in detail, should be appreciated that inner flap 410B is the mirror image of the outer flap 410A comprising ring portion and/or perforation as above.

The distal portions 405B of footwear back portion 210 comprises toe case 150, and toe case 150 covers/hold the toe of wearer.In the illustrated embodiment in which, toe case 150 comprise basic horizontal top cover 435A (it is configured to the toe across pin) and from top cover to the edge of downward-extension or lip 435B (such as, edge can be oriented to and be approximately perpendicular to top cover 435A).Toe case 150 is configured to work in coordination with the pin leading portion supporting zone 345B of flat support, to limit the single cavity of all toes of the receiving pin in top 105.With cardinal extremity part 405A similarly, distal portions 405B also can comprise being operable as and allows the perforation 430 that extends there through of fluid.

In one embodiment, footwear back portion 210 has single (single-piece) structure.In addition, toe case 150 can be shaping (three-dimensional) structure without making.In another embodiment, toe case 150 is seamless.

Each in planar section 205 and footwear back portion 210 is shaped by compression forming process (will discuss in more detail below)/and shaping.Compression forming allows the formation of the fabric lamination with unique geometry (such as, predetermined macrostructure and microstructure).That is, except the seamless heel cup 340 (macrostructure) of planar section 205, toe case 150 can also comprise the fluctuating shape pattern (microstructure) defining the one or more toe guiding pieces be integrated in footwear back portion 210.With reference to figure 5A, Fig. 5 B and Fig. 5 C, toe case 150 comprises multiple toe guiding piece 505A, 505B, 505C, 505D, 505E, each toe guiding piece is operable as and toe is positioned at precalculated position (outer fix of specifying such as, in top) in toe case cavity 507 and/or the precalculated position relative to adjacent toe.For example, the distal portions 405B of footwear back portion 210 comprises and extends to one or more butt shape wall in toe case cavity 507 or separator (being also referred to as end finger stop part).Separator deflection or guiding toe arrive the precalculated position relative to top 105 and/or adjacent toe.In one embodiment, separator is from cover plate (towards footwear sole construction 110) extension downwards of toe case 150.In another embodiment, separator upwards extends (not shown) from the flat support 315B of planar section 205.

In a preferred embodiment, toe guiding piece 505A to 505E limited by integration (such as, shaping) a series of depressed regions in top 105 (specifically, toe case 150) and elevated regions.Specifically, the top of toe case 150 rises and falls, thus defines one or more elevated regions 515A to 515E (each elevated regions has summit 520A to 520E) and one or more depressed regions 525A to 525D (each depressed regions has valley point 530A to 530D).Utilize this structure, each elevated regions 515A to 515E defines the microscler open channels or half cylindrical shell 517A to 517E (in a preferred embodiment, passage 517A to 517E not exclusively surrounds toe) that can be operating as a part of receiving toe.Depressed regions 525A to 525D and elevated regions adjoin, and enter in the passage 517A to 517E of elevated regions 515A to 515E to the degree of depth that downward-extension is enough to guide toe.Each elevated regions 515A to 515E aims at substantially with corresponding toe, and each depressed regions 525A to 525D aims at substantially with the corresponding space between toe.Correspondingly, each passage 517A to 517E receives a toe of wearer.Specifically, in the embodiment illustrated, first toe guiding piece 505A (the passage 517A limited by elevated regions 515A) receives big toe (pin thumb), second toe guiding piece 505B (the passage 517B limited by elevated regions 515B) receives the second toe (two toes), 3rd toe guiding piece 505C (the passage 517C limited by elevated regions 515C) receives the 3rd toe (middle toe), 4th toe guiding piece 505D (the passage 517D limited by elevated regions 515D) receives the 4th toe (fourth toe), and the 5th toe guiding piece 505E (the passage 517E limited by elevated regions 515E) receives the 5th toe (little toe).In addition, inner side toe (big toe) and outside toe (little toe) are directed in its corresponding toe guiding piece 505A and 505E by the outer wall 540,545 of case respectively.

In each toe guiding piece, each elevated regions 515A to 515E and/or depressed regions 525A to 525D can be similar each other; As selection, the height in these regions can be different.That is, the distance measured by from the top side of footwear sole construction 110 (and/or flat support 315B) to summit 520A to 520E or valley point 530A to 530D can be identical or different.For example, the height of elevated regions 515A to 515E can reduce continuously along the transverse direction of footwear, and wherein the first toe guiding piece 505A has maximum height and the 5th toe guiding piece 505E has minimum height.

In one embodiment, valley point 530A to 530D extends in toe case cavity 507 with such degree of depth: enable separator interact (contact/deflect toe) with the toe being positioned at cavity, but still allow toe to pass through from the below of depressed regions 525A to 525D, thus user is allowed to expect and artificially reorientation/movement/bending toe by it.In other words, because the separator limited by depressed regions 525A to 525D not exclusively extends through toe case cavity 507, therefore between the far-end (that is, the valley point 530A to 530D of depressed regions 525A to 525D) and flat support 315B of separator, there is form valley point or recessed gap 532 space or gap.Recessed gap 532 can have any height h1 of the object be suitable for described by it.For example, the height h1 in recessed gap 532 is selected as allowing user's artificially reorientation toe in toe case 150 when needed.The height h1 in the recessed gap 532 of each depressed regions 525A to 525D can be consistent, or can be different between depressed regions.

Similarly, apex height h2, namely the height h2 (gap, summit) measured by the summit 520A to 520E from flat support 315B to elevated regions 515A can be any height of the object be suitable for described by it, and can be identical or different between toe guiding piece 505A to 505E.In the illustrated embodiment in which, apex height h2 is higher than recessed height h1.

Utilize this structure, the degree of depth of each toe guiding piece 505A to 505E-each elevated regions-have part (that is, the upper part/region of toe) effectively receiving toe.For example, the degree of depth of toe guiding piece 505A to 505E can be configured to receive/surround about 10% to 50% of toe, and preferably receives/surround about 15% to 40% of toe.

Each elevated regions 515A to 515E and depressed regions 525A to 525D longitudinally can extend along toe case 150, transversely (that is, across the width of footwear) distanced from one another crossly to open, make wall substantially parallel.Toe guiding piece 505A to 505E can have any height of the object be suitable for described by it.For example, each elevated regions 515A to 515E and depressed regions 525A to 525D can extend and end near instep portion 145 the flap connector 425 of article of footwear 10 (such as, near) from the front of toe case 150.

As shown in the figure, each elevated regions 515A to 515E and depressed regions 525A to 525D defines level and smooth curved surface, and this curved surface is using the outer surface of toe as profile.Width w1, w2, w3, w4, w5 of each toe guiding piece 505A to 505E can be identical, also can be different to adapt to the different in width of the toe on pin.For example, the width w1 of the first toe guiding piece 505A (being configured to receive big toe) can be greater than the width w3 of the 3rd toe guiding piece 505C (being configured to receive middle toe).In addition, the width w3 of the 3rd toe guiding piece 505C can be greater than the width w5 of the 5th toe guiding piece 505E (being configured to receive little toe).

Utilize above-mentioned structure, each toe is remained on its physical slot by toe guiding piece 505A to 505E, guides or limit the transverse shifting of each toe.When operating, when pin is inserted in suitable article of footwear by wearer, the separator formed by depressed regions 525A to 525D guides each toe to enter in its corresponding elevated regions passage.Using (that is, pin static or moving) time, toe associated with it is directed in elevated regions passage by separator continuously, to be remained on by toe in its respective guiding piece 505A to 505E.In other words, toe guiding piece 505A to 505E can be configured to laterally bend each toe, drives adjacent toe away from each other, make each toe and the toe be adjacent slightly spaced apart/be separated.In addition, toe guiding piece 505A to 505E keeps the position of each toe by preventing toe transverse shifting during using (such as, when running).Correspondingly, toe guiding piece 505A to 505E makes each toe keep stable, and the inside reducing the pin of user is moved or skids, and the ability that balance is provided of auxiliary each independent toe.This optimizes performance and the comfortableness of wearer conversely.

The above-mentioned structure on top 105 provides toe case 150 that is single, that open wide cavity, this toe case receives all toes, and while the transverse shifting of restriction toe, still allow user to handle toe and desirably reorientation toe in toe case cavity 507.This with provide a series of independent cavity, each cavity different for the known superstructure of a toe.In these known configuration, each toe is enclosed in its oneself cavity completely, and each cavity can be movable independently.Therefore, conventional structure does not provide single unlimited cavity.

Utilize above-mentioned superstructure, provide the motion of two kinds of ranks during use.First, whole toe case 150 moves as individual unit, and the sole of the foot ball-pivot around pin turns (such as, along the sweep of footwear sole construction 110, will discuss in more detail below).Secondly, still allowing toe naturally while movement, by toe guiding piece 505A to 505E, toe being scattered in toe case, this alleviates the pile-up of toe.Which in turn increases wearer's comfortableness during use, and more naturally feel for wearer provides (feeling barefoot).

As mentioned above, planar section 205 can be connected with footwear back portion 210 in a seamless manner and/or without mode of making.In one embodiment, attachment 215 make footwear back portion 210 engage with planar section 205 (such as, connecting).Specifically, top 105 comprises the inner side attachment of the outside attachment 215 arranged in the outside along top and the disposed inboard along top.For example, by webbings such as such as hot sticky crossed belts (such as, can from the commercially available BEMIS seam connecting belt of BemisAssociatesInc., Shirley, MA), each several part 205,210 on top 105 is coupled together.In a preferred embodiment, attachment 215 comprise and fabric (such as, polyester, spandex etc.) like the dry goods on formation top.

As mentioned above, the fin of footwear back portion 210 substantially with edge 355A, 355B, 360A, 360B of planar section 210 for profile.Correspondingly, planar section 205 mates with footwear back portion 210.Specifically, make the outer flap 410A of footwear back portion 210 and inner flap 410B be in adjacent relation with lateral wall 330A, 355A of heel cup 340 and madial wall 330B, 355B and planar section 205 respectively, wherein the outer flap 410A of footwear back portion 210 and inner flap 410B is to cut with the mode of planar section 205 complementation.Corresponding edge 235A, 235B, 260A, 260B are sewn into together, and apply attachment 215 (such as, webbing), to make the connecting portion between attachment bridge joint each several part 205,210 and to cover sewing unit.Preferably, on attachment 215 inner surface that is arranged in top 105 and outer surface.Then, heat is applied so that sealing joints to attachment 215, make attachment be fixed on top 105.

Utilize this structure, attachment 215 provide the seamless link of the friction minimizing and/or eliminate caused by (exposing) seam of routine.That is, substantially do not interrupt and/or continuous print surface, because herein is provided seamless link because attachment 215 define along the inner surface on top 105 and/or outer surface.

As selection, seam between can using across adjacent part and the thermoplastic film be bonded together by each several part 205,210 are (such as, can from BemisAssociatesInc., the SEWFREE band that Shirley, MA are commercially available) planar section 205 and footwear back portion 210 are seamlessly coupled together.

In other embodiments, ultrasonic bonding can be used.In one embodiment, various piece is combined by ultrasonic bonding, and weld seam covered by the band of heat seal film.

In another embodiment, attachment 215 can have shape that is bending or that rise and fall, to follow the profile of connected upper part 205,210.

Once top is formed, then pass through adhesive, welding (such as, ultrasonic bonding) etc. by formed upper bond (such as, installing) on footwear sole construction 110.

Top 105 can comprise any material of the object be suitable for described by it.Specifically, top 105 can be formed by the material of the three-dimensional structure that can be formed as described above (such as, comprising the structure of toe guiding piece).For example, top 105 can be formed by fabric laminate.For another example, top 105 can be formed by the fabric laminate that can be shaped by compression forming.For another example, top 105 is formed by the fabric laminate comprising froth bed.

Compression forming is such forming method: wherein, first moulding material is placed in cavity body of mould that is unlimited, that heat.With top reinforcing or plug member, mould is closed, apply pressure and contact with whole die region to force material, keep heat and pressure, until moulding material solidifies simultaneously.Figure 6 illustrates exemplary compression shaped device.As shown in the figure, compression-molding apparatus 605 comprises first or concave type moulding section 610, and this first moulding section 610 is configured to receiving second or plug-in type moulding section 615, and this second moulding section 615 has the shape with the shape complementarity of the first moulding section.Can to be shaped single layer by operative installations 605, or can be shaped sandwich construction by operative installations 605.In the embodiment shown in fig. 6, the top 105 formed comprises three layer-exterior layers or outer 620, middle part layer or intermediate layer 625 and interior layer or internal layer 630.For example, outer 620 can be breathable synthetic textiles (such as, polyester textile), intermediate layer 625 can be open celled foam (such as, vinylacetate), and internal layer 630 can be breathable synthetic textiles (such as, polyester textile).

In addition, outer 620 and/or internal layer 630 can also comprise elastomer (such as, spandex or elastomer), to provide elastic property for layer.In one embodiment, outer 620 is fabric (the weight 215g/m comprising the polyester of 85% and the spandex of 15% ²), intermediate layer 625 is polyurethane foams, and internal layer 630 is fabric (the weight 210g/m comprising the polyester of 79% and the spandex of 21% ²).

Outer fabric layer 620 and inner textile layer 630 can have similar or different character (such as extensibility).For example, outer 620 can have the percentage elongation along length larger than internal layer 630, and internal layer 630 can have the percentage elongation along width larger than skin 620.

In other embodiments, skin 620 and/or internal layer 630 can be formed by leather, GORE-TEX (GORETEX) etc.

In the process of compression (and applying heat), layer 620,625,630 is glued together, and forms fabric laminate.In addition, fabric laminate conforms to the shape of moulding section 610,615, and permanently keeps its shape.By this way, the planar section 205 with mold shape and the footwear back portion 210 on top 105 can be formed.
