Description

Sole assembly for article of footwear

Technical field

The present invention relates to footwear, and in particular to the sole assembly for article of footwear.

Background technology

Owing to footwear the most generally exist, people are easy to underestimate to meet on footwear needed for increasing need The complexity of engineering.For the performance used in (such as sports and other sports) it is contemplated that performance application Footwear, the most so.

Running shoes are the one in the footwear of most advanced kind.Running is exigent activity, and in this activity, footwear play Important function.For running shoes, it is important that meet while lightweight and height is durable and buffering and energy are returned High-tech specification.One effect of running shoes is that the health of protection runner is not by during the stage contacted with ground of stride The impact of the excessive localised load produced.Elastic foam is the collision using to absorb between foot and ground in the sole of footwear One example of the material of some impact energys.During the preshoot stage of contact, when runner pushes ground, oneself is lifted to sky Time in gas, generally produce bigger power.These power are applied by the forward foot in a step of runner.In this stage of stride, under the forward foot in a step The Main Function of padded coaming is not to reduce these power, but reduces local peaking's pressure by consistent with the shape of foot.Front The sole of underfooting performs secondary action also by the stride dynamic compression of response runner with decompression.

Typical footwear structure creates one layer of non-stretching fabric, its sole being bonded to be positioned at runner underfooting.Generally in fortune In dynamic construction of footwear, upper of a shoe is fitted to pincers side (lasting) to form it into the 3D shape of needs, and then, footwear The bottom of side utilizes the plain film of the shape of the bottom substantially clamping side to close.This can be realized by multiple technologies, including wrench side, slides Dynamic pincers side and Shi Duobao (strobel) sew up.Bottom Shi Duobao stitching, available such as sawtooth seam is sewed up in the closing in upper of a shoe Close or realize from scholar's many precious stitchings of many precious quilting machine taxis." strobel board " in this technology can be by usually textile The multiple material manufacture of (non-woven, weave, weave).The shape that an exemplary requirement is its holding upper of a shoe for strobel board Shape；In the ideal case, plate insignificantly stretches, the most in the longitudinal direction.The layer of this relative stiffness limits footwear and is running The ability of the foot of runner is met under the load typically applied during step.

Traditional running shoe generally includes inner bottom (also referred to as inner sole, middle pad or shoe pad), and it is above strobel board In the foot reception cavity being positioned in upper of a shoe.Inner bottom is typically manufactured by ethylene vinyl acetate or " EVA ".Because inner bottom is relatively Immediately below foot, one layer of padded coaming is provided, so it generally improves comfort level above the strobel board of rigidity.Apply at some In, thin froth bed is positioned at above strobel board and below inner bottom.The main purpose of this thin froth bed is to improve wearer Foot the local pressure of the sole of footwear is distributed.Such as, the sheet material of thin (the such as 1-3mm) of foam (usually EVA) can be laminated To the fabric of strobel board to form foam-strobel board laminate.The froth bed of empirical discovery lamination can provide relaxing of improvement Appropriateness.No matter whether sole includes inner bottom and/or strobel board laminate, only includes EVA and other class above strobel board In terms of creating the most comfortable platform, there is limited ability like the conventional sole structure of padded coaming.This defect is due to many Kind of reason produces, and (especially closes including the thickness limitation of froth bed, the mechanical stiffness characteristic limitation of froth bed, mechanical damage In non-durable foam) and/or limit by foam layer being pressed onto the compression of the froth bed that the many precious materials of non-stretching taxi give. Such as, the structure only including foam-strobel board laminate is the thinnest to such an extent as to works as typical case during the preshoot stage of running step Ground can not meet the shape of the forward foot in a step fully when producing the highest ground force.Very simple, do not have enough thickness/materials Whole blastic deformations is responsible for so that the forward foot in a step (or one part) will be positioned on the many precious base plates of lower section taxi " bottoming out ".This Outward, Shi Duobao is not extend to the whole width of the forward foot in a step, so, the many precious laminates of foam-scholar do not cover whole contact areas of foot. As another example, utilize the inner bottom including traditional eva foam (individually or being combined) with foam-strobel board laminate Structure, inner bottom (and foam-strobel board laminate) is affected over time by irreversible plastic deformation so that it can not be abundant Bounce-back.Therefore, combine above strobel board traditional E VA foam structure will the thinnest to such an extent as to can not be complete under peak load Entirely meet the shape of the forward foot in a step, or the thickest making will substantially change the suitable of footwear by repeating to load the permanent compression set caused Right.

Foam of the upper end.

As discussed above, it is desired to be the upper end 22 had some machinery spy limited by be suitable in strobel board using The foam manufacture of property.For example it may be desirable to foam of the upper end 22 is submissive, elastic, durable and high comfort.Separately Outward, because foam of the upper end 22 can be laminated to strobel board, so, it will be also useful that foam of the upper end 22 can be sewn.

About modulus, it may be desirable to foam of the upper end 22 compares traditional midsole foam (interlayer bubble at the bottom of such as EVA shoe Foam) there is relatively low modulus.Using relatively low modulus eva foam to there is physical constraints in footwear, reason is relatively low modulus Rapid Damage under the load that eva foam is formed during the peak value forward foot in a step loads.The example damaged can not be returned after being included in load Bullet (such as permanent compression), tear etc..In order to avoid the eva foam of premature breakdown, relatively low modulus only can be in relatively thin layer (example Such as 1-3mm) middle use.Regrettably, the use of thin froth bed limits adaptability, and adaptability is the important of the sole under the forward foot in a step Target.As a result, it is desirable to foam of the upper end 22 in layer substantially resistant to sufficiently thick with in forward foot in a step load and adjoint curved with, described layer During song, laminating foot, will not lose its characteristic in iterative cycles.In various embodiments, the upper end 22, does not has eva foam.

In view of these targets, the upper end 22, is by soft and high resiliency (energy efficiency) and durable material manufacture.For The example of the suitable foam of the purpose of present disclosure includes some thermoplastic polyurethane expanded (" E-TPU ") foam and heat Thermoplastic elastic (" TPE ") foam.In certain embodiments, the upper end 22 include E-TPU foam, substantially by or steeped by E-TPU Foam forms.In other embodiments, the upper end 22 include TPE foam, substantially by or be made up of TPE foam.

The particular example of suitable foam includes commercially to obtain from the Guo Sheng in Chi Dian town, Fujian province Jinjiang City " 180SD " the E-TPU foam arrived；The high resilience TPE that commercially can obtain from the Ecocell in southern city, Dongguan, Guangdong city of China PH-60 foam；" X-Bounce 45 " foam that commercially can obtain from the Fine Chemical of QingNan, Korea gold sea market；? " S-Lite " foam that can obtain from the Superfoam in Dongguan, Guangdong city of China on market；And commercially can be from New Jersey " the Infingergy that not BASF AG of Lip river Farnham Parker obtains^TM" foam.

Foam of the upper end 22 is elastomeric, and (those being such as subject to when standing) steep than EVA under relatively low stress Foam is submissiveer and changes more resistance for thickness after repeated stock.In particular, foam of the upper end 22 especially can be in the forward foot in a step Middle offer is beyond the superior function of EVA strobel board.The flexibility of foam of the upper end 22 allows the comfortable of increase when the forward foot in a step is clashed into Property and supplementary impact absorbing.Additionally, foam of the upper end 22 provides benefit during preshoot.Exactly, foam of the upper end 22 is contacting to earth The shearing force of release when period absorption toe is liftoff.The energy efficiency of the increase of foam of the upper end 22 can produce more effective stride.

Being used for manufacturing the foam at the end 22 and have " compliance ", " elastic " and the mechanical property of " ruggedness ", it passes through Sample of material carries out impact test limit.Such as, the mechanical property of foamed materials may utilize Electromagnetic Drive impact test Device (ElectroPuls E3000, Instron, promise Wood, Massachusetts) is measured.Agreement can be ASTM F1614-99 (2006) revision " for standard test method code C of material system shock-absorbing capacity of sport footwear ".Principle is revised It it is the disk samples (the minimum square sample relative to 3 inches) using 45mm.

Control load curve to clash into simulation foot.Sample about 20mm thickness (and obtained data are by thickness calibration Change).The mechanical attributes paid close attention to includes mean rigidity, energy efficiency, dynamic compression permanent deformation, and foam 535 kPas this The mean rigidity of card (kPa).Herein, the typical surge pressure during 535kPa clashes into selected as foot.In order to make the upper end 22 Foam " soft " and " flexible ", paying close attention to noticeable mechanical attributes is average modulus and energy efficiency.By impact punching The cross section (using 45mm diameter impulse face or " ram ") in face counts and is multiplied by the thickness of sample average firm as factor Degree is standardized as average modulus.Energy efficiency refers to the ratio of the energy that the energy that sample returns absorbs divided by sample.

Each foam sample by impact test 1000 times to obtain the reference measurement result of mechanical features.980th time, 990 Secondary and 1000 Secondary Shocks circulation is averaged to determine attribute.

Dynamic compression permanent deformation is used to measure as durability.Dynamic compression permanent deformation be sample thickness for Surely the change of quantity is impacted.Each foam sample (is wrapped to obtain the reference measurement result of mechanical features for 1000 times by impact test Include average modulus and energy efficiency), then impact test 100000 times (there is identical load profile) bearing with simulation extension Carry circulation, and the measurement result of 1000 mechanical featuress after being loaded of impact test the most again.

The foam at the upper end 22 in various embodiments, being used for manufacturing present disclosure has from about 750 to about 950kPa, About 800 to about 950kPa, the average modulus of about 850 to about 950kPa or about 875 to 950kPa.According to ASTM F1614-99 (2006) revision analyzes average modulus under the stress of 535kP.Foam also has at least about 78%, at least about 80%, Or the energy efficiency of at least about 82%.Revision analysing energy efficiency according to ASTM F1614-99 (2006).Additionally, Foam has less than about 10%, the dynamic compression permanent deformation of less than about 8% or less than about 6%.According to ASTM F1614-99 (2006) revision analyzes dynamic compression permanent deformation.Asker c-type durometer can be used to determine Asker C hardness Value.

Due to the material behavior of foam of the upper end 22, they can not prematurely lose its machinery so that bigger thickness uses Characteristic.Foam of the upper end 22 not only provides the mechanical property of improvement, and by the upper end 22 was positioned at above strobel board 16, on The end 22, also makes the layer foot further away from each other relative stiffness formed by strobel board 16 and binding agent, incomparable inconsistent move.

In various embodiments, the upper end 22, is generally of from about 1mm to about 10mm, about 2mm to about in forefoot region 7mm, or about 2mm is to the average thickness of about 5mm.It is understood that the thickness at the upper end 22 structure based on such as footwear, Whole user etc. can be identical or can change.The thickness at the upper end 22 changes along with the difference in the region in footwear.Such as, exist Forefoot region, the upper end 22, can have at about 2mm to the scope of about 10mm or the thickness in about 3mm to the scope of about 7mm, And in heel area, the upper end 22, can have in about 1mm to the scope of about 7mm or the thickness in about 2mm to the scope of about 5mm Degree.In the embodiment in figure 1, the upper end 22, has the maximum gauge of about 5mm and in whole heel area in central authorities' forefoot region There is the thickness of about 3mm.Arch area progressively transition between 5mm and 3mm can be run through in the upper end 22.
