Description
Technical field
The present invention relates to footwear, such as shoes, boots and sandals.
Background technology
Traditional footwear comprise and the outsole of earth surface (footwear outer bottom) and the insole (inner sole) of pin cushioning user.
Footwear such as (general) shoes and the boots closed also have vamp to encase and angle.
For clarity sake, term " footwear " relates to outer footwear in this manual, such as shoes, boots, sandals, and does not comprise the fabric product be through on pin, such as socks, stocking, tight and panty hose.
The known footwear of conventional shoes comprises the sole of cushioning to provide comfort level.But, regardless of design or the building method of conventional soles, they are all based on the principle of compression buffering.In other words, when the weight of pin puts on sole, the buffering of conventional foam is subject to the compressed by weight of people.Therefore comfort level is provided by the shock-absorbing capacity of material for sole of shoe under compression.
Attempt many options to improve the shock-absorbing capacity of sole, comprised dissimilar foamed material and density, air pocket, adjustable air-pressure chamber, embed ball, spring etc.But, these all methods are still based on the compression of padded coaming.
The US Patent No. 6 of Kendall, 601,321 and US7,555, the footwear of the suspension braiding lattice that 847 disclose one has " high tensile, low ' elasticity ' fiber ", also point out " in all described embodiments, the main supporting part of lattice be non-elastomer polymer or based on the homogeneity of metal or composite fibre or yarn ".
The present invention avoids the described structure that can not bend (unyielding), and proposes a kind of diverse structure, and described structure has the bearing net formed by the elastomer of flexibility.
Summary of the invention
The present invention can be used for construction of footwear (such as shoes) or the part as construction of footwear, it is characterized in that having suspension elastomer net or grid, and the pin of user is by described suspension elastomer net or lattice support in use.
As mentioned before, one aspect of the present invention provides the footwear sole construction for footwear, and described footwear sole construction comprises suspension elastomer net or the grid of the pin of the wearer supporting footwear.
The present invention advantageously provides a kind of structure of the uniqueness for footwear, wherein characteristics of principle eliminates the needs for compression buffer soles design usually, the substitute is the elastomer grid or net that adopt the flexibility suspended, it is under the reclinate tension force effect passing through pin weight, reaction force is upwards provided, to support the weight applied by the pin of wearer, some is similar to resilient hammock.
Feature desired by least one form of the present invention is the conventional compression buffering by providing elastomer net or grid thoroughly to change sole, described elastomer net or grid suspend via outer bottom edge, at least part of periphery, and most of weight of pin is absorbed by net/grid.The weight applied by pin makes net be bent downwardly, but the net/grid that stretched in this case, make its elastomeric material be in tension state.In fact this represent that some is suspended in the outer bottom of ground or elasticity " hammock " to pin a little, in the periphery being suspended in footwear sole construction or outer rim.
Air circulation/air circulation is also a very important problem, because the liner that traditional shoes are combined with smooth region usually contacts with pin, makes the non-constant that ventilates.Although some shoes and sandals have been designed to have little groove to improve air circulation, still need the contact of sizable buffer area according to definition and there is no enough air circulations/air circulation.
Elastomeric net/grid the footwear suspended can provide fabulous ventilation, because the mesh design of opening makes most pin to breathe due to the low surface area physical contact with net/grid.
The most important thing is, should be appreciated that net/grid elastomer not only provides comfort level and ventilation, and dramatically reduce the pressure to limbs such as ankle and knee.Because grid is flexible elasticity/elastomeric material, so it gently can bend and rebound to ease off the pressure on the impact of knee, ankle etc.
Net or grid are designed to be bent downwardly and enter gap/interval/space below net/grid (namely, at net/between grid and outer bottom, or for the footwear of the sole of opening when ground engaging portions is supporting network/grid peripheral at net/between grid and ground).
During normal walking, if be applied with large downward power (such as 50kg or jump land), then grid can be bent downwardly until contact sole or ground.
Therefore in the space/interval described at least some or gap, also soft foam may be comprised.If downward power is enough large, therefore net/grid may touch foam, itself then the pressure of the bottom being applied to sole can be relaxed.Importantly, although net/grid is " touch the end ", it has still absorbed most downward power and impulsive force in this process, and along with net/grid be back to more normal position can then this power of the certain percentage that rebounds.In fact, bounce-back is the characteristic can noticed immediately of footwear.This can reduce the energy applied by wearer effectively, if especially stair climbing etc.
In the situation of described high load capacity, because net has absorbed the initial load of larger percentage, mean that foam can more soft (for common shoes, foam must carry whole load) than usual, highlights the comfort level of shoes further.
Footwear net or grid/net stretch across shoe base outer rim and such as hold knot (endknobs) or ring (loops) to be fixed to outward flange by ledge, to fit into or to mate on the corresponding recess being designed in outer part of footwear respectively or lug.
Flexible net/grid/net is molded as flat usually by injection molding, and desirable examples material is flexible polyurethane thermoplastic elastomer (TPE), such as used in surfboard pin rope or belt.This properties of materials has fabulous stretching and bounce-back ability.
The hardness number that net/grid elastomer can have is 30-120 shore A (ShoreA), more preferably between 80 and 95 shore A (90A is very typical), to provide the required elastomeric stretch characteristic with enough weight support.Commercial example injection grade elastomer comprises BASFElastollan1185 and BAYERDesmopan385S (RTMs).BASFElastollan and BAYERDesmopan is injection grade thermoplastic.
Interchangeable elastomer is the Erapol of EraPlastics, and it is chemical group (non-injection grade) polymer, is listed in ' prepolymer of the isocyanate terminated end-blocking of the liquid based on PTMEG PPG '.Other elastomer comprises polyurethane surface and reveals the suitable elastic characteristic and intensity that can be utilized.
The method of attachment except ring set crosses corresponding shoe base ledge such as ' hook ' can be adopted, comprise the design of such as projection/knot and groove (knobsandslotted).But, an option is that net and sole outer edge thereof are molded as parts.This can realize by being molded by the single injection of same material or being utilized the rubber-coating module technique of different materials (combining in double injection bag molding process process).
Net or grid can be configured to be in pretension state in a mold, and once outsole and/or shoe base are molded around it, still keep pretension upon exiting the die.
Another option of at least one embodiment of the present invention upright or vertical outward flange or outer rim (such as outsole or outer bottom) and shoe base is molded together become parts.Alternatively, if the problem of being combined with, they can become parts by rubber-coating module.Elastomer net/grid is connected to base by elastomeric ring, as described above.

Detailed description of the invention
The present invention will be described in conjunction with two embodiments, but should be appreciated that scope of the present invention is not limited to described embodiment.
Fig. 1-4,5-6,7 and 8-10 respectively illustrate and embody four examples of footwear of the present invention.
Fig. 1-4 shows net/grid molded separately together with two other parts; (it also may tie up in conjunction with vamp in mould central body, as Figure 1-4) and the sole of higher density material itself, and combine bending reinforcement lug, its provide lateral stiffness with prevent footwear from net/grid once inwardly sink under the tension force effect being hooked to position.
Only there is shoe base to need to be incorporated into the coupling lip of central body, make between net and shoe base, to have enough interval/gaps so that net can be bent downwardly under the weight effect of pin.Shoe base can be the polyurethane elastomer of the higher density in 65D magnitude usually, with guarantee outer sole at net pretension or act on online pin gravity can not inwardly sink.Generally speaking, this results in complete sandals, only need to add fastener constructions such as hook and look fasteners and optional liner to make product complete.
Should be appreciated that one or more interchangeable embodiment of the present invention has to be molded together as the upright or vertical outward flange of parts or outer rim (such as, outsole or footwear outer bottom) and shoe base.Alternatively, if combining/connecting is a problem, they can become parts by rubber-coating module.Elastomer net/grid is connected to base by elastomeric ring, as described above.
Net/grid can have grid type pattern or geometric layout such as hexagon net or more " organic " or irregular structure/pattern, is designed to the load absorbing pin specially.
In addition, footwear mold can be combined with vamp (footwear top) as an option, the design of such as common leather or running shoes pattern or the sandals design as shown in the example of Fig. 1-4.
As the front and rear band of example to being included in single parts central body injection molding or rubber-coating module design technology, and mold layout can be flat or band is become close to an angle of 90 degrees relative to net/grid.
Alternatively, front and rear band is to being omitted, and other common traditional pattern vamp such as running shoes etc. combinedly can have net-footwear net/grid, outsole design theory.
These footwear top/vamps are attached to the outer top section of central body by traditional known way.
Fig. 5 and 6 shows the second example embodying construction of footwear of the present invention.This structural system utilizes the net/grid of identical type, is hooked on the lug of " comb " shape structure unlike the end loops on every side of footwear outside or spat with grid.
" comb " normally metal grid (material also can be synthetic material, the such as injection-molded plastic of carbon or hard reinforcing), the lug comprising the net end ring on top section and the tooth fitted on the base section of the groove in corresponding sole/spat outside.Net subsequently by cross directional stretch and end ring be hooked on the comb of every side, make net/grid can suitably absorb pin weight under the effect of pretension, and can not shoe base be bended downward into very much.
Fig. 7 shows the 3rd example embodiment embodying construction of footwear of the present invention.This structural system is similar to aforesaid second example, but has the advantage being easier to manufacture, and is more suitable for current footwear production technology.Be different from and have comb (son) shape structure on every side of footwear, the 3rd embodiment adopts simple stake holes structure.
Sole comprises U-shaped metal wire (or not pliable material) stake, in conjunction with the horizontal component being oriented to span sole.The rigidity/hardness provided stops footwear inwardly to sink when net/grid/net to be crossed by cross directional stretch.The vertical component of U-shaped stake is designed to the mating hole inserting H-shaped footwear mid portion.This H-shaped mid portion combine run through and the net of involved stake holes/elastomeric vertical component of grid/net around net/grid/net.
Lower sole portion (having line stake) Upward match enters H-shaped mid portion (having hole), and vamp coupling thereon.H-shaped mid portion is pulled outwardly to be stretched to be arranged in the corresponding stake of sole, applies prestretching force to help feet weight to net/grid/net.
Fig. 8,8A, 9 and 10 show the 4th example embodiment embodying construction of footwear of the present invention.This structural system is similar to aforesaid second and the 3rd example, but has more direct manufacture method, does not require any additionally structural auxiliary, such as U-shaped metal wire etc.This needs ' H ' shape cross section moulded parts, and wherein the external vertical part of ' H ' shape is molded elastomer/rubber/urethanes, and the horizontal component of ' H ' shape is net/grid, is molded as parts by identical material.Although be described as being molded as parts, also may be molded net/grid respectively and the peripheral edge portion of encapsulate molded vertical, or vice versa, or its combination.
In each embodiment of the invention, net/grid is pretension.If do not have pretension, net/grid when people applies gravity downwards by pin through being easy to bend downward into shoe base very much, and may provide enough drags in the short distance of net/grid not between net/grid and the upper surface of ground or outsole.
Pretension does not also mean that net needs unnecessary stretching; But it only represents that disclosed net did not sink before applying gravity.Therefore, preferably net and vertical outer rim are molded as a part, and add sole and vamp on the net in conjunction with enough pretensions by simple.
Footwear design in conjunction with many various combinations is feasible, the footwear design of described many various combinations in conjunction with the present invention to adapt to footwear market.Such as, sandals, traditional footwear, running shoes, trainer shoe, sport footwear, flip-flop/flip-flop, boots etc.Utilize the design principle of one embodiment of the present of invention almost can be applied to any type of outer footwear type.
