Description

Outer bottom with tangential deformation ability

The present patent application is Application No. 200680005720.0 (international application no is PCT/CH2006/000114), hair Bright entitled " there is the outer bottom of tangential deformation ability ", the divisional application of the application that the applying date is on 2 23rd, 2006.

Technical field

The present invention relates to a kind of outer bottom, particularly for the outer bottom of sport footwear, the outer bottom can tangentially forwardly and rearwardly Elastic deformation, and ability is substantially firm relative to tangential deformation only in the critical strain in beyond now deformed zone 's.

Here, tangential deformation is interpreted as example by shearing force along tangent or parallel with the two-dimentional limit of outer bottom or its sole The deformation that causes of direction.For example by the deformation in the edge that causes of the compression direction vertical with the two-dimentional limit of outer bottom or its sole Necessarily unlike this.Tangential approximately consistent with horizontal direction, vertical direction is approximately consistent with the vertical direction on horizontal basal plane.

Background technology

The outer bottom of known substantial amounts of easy elastic bending in different constructions, these outer bottoms use the different elastic material of hardness Material.And the known outer bottom for being embedded with air cushion or rubber cushion.They are used to be buffered in the stress produced during running, in this way The kinematic system of runner, particularly joint are protected, and gives comfortable running and felt.

Most of commercially available running shoes for Sport Utility at present have elasticity, and the elasticity can be compressed in sole When it is main vertically or along perpendicular to the direction of sole enter row buffering, but the sole in the horizontal direction with it is circumferentially opposite It is firm and pin it is at an angle inclination contact to earth when will not fully bend.So the reason for, may lie also in sole along level side To larger deformability can produce a kind of floating effect, this can cause unfavorable shadow to the stability and balance of runner Ring.And each step of runner can all lose some distances, because sole can be touched when being left from shock point first along with pin The direction in opposite direction on ground slightly deforms.Certainly to a certain extent, generated in traditional commodity sport footwear floating Dynamic effect.In order to avoid the effect, front area (pushing away power generally thus to produce) phase of the sole of most of these sport footwears To harder and be configured to bend.

On the other hand, despite the presence of described tangential deformability, but the above-mentioned type disclosed in WO 03/102430 Outer bottom avoid floating effect because when beyond the critical strain of at least one of now deformed zone, these outer bottom phases It is substantially firm for tangential deformation.For runner, after critical strain is reached, in corresponding step or stress There is reliable attitude on point, he can be again left without loss distance from the attitude.

In WO 03/102430, different examples are described, cutting for sole can be preferably understood by these examples To deformability and the solution principle of its rigidity for exceeding at least one critical strain.For example, describing elastomeric material The cannulated element being made, the element, but simultaneously also can be by completely forward especially under tangential deformation under vertical deformation Compress backward, further tangential deformation is then prevented due to the friction between their upper half-shell and housing lower half.

EP 1264556 discloses a kind of outer bottom for sport footwear, and the sole of the outer bottom has softer outer layer and harder Internal layer.Projection at harder internal layer is penetrated softer outer layer and is protruded in the form of support member beyond the outer layer.It is logical The support member is crossed without for sole provides tangential deformability and prevents the tangential deformability.

There is similar structure from sole known to FR 2709929, internal layer is provided with sharp metal tip.

UK 2285569 discloses a kind of trainer shoe with such sole, the sole have bending the first element and The second firm element.First element is towards rear portion is along the direction inclination at an angle of heel and exists in the direction under loads Compressed between the second hard element, subsequent second element bears load.Cloth due to the first element relative to the second element Put, corresponding deformation of first element towards front portion is impossible.

JP 5309001 discloses a kind of footwear with such sole, and the sole is arranged on the interior zone with projection In, these projections tangential deformation and can be provided with cavity in all directions.The interior zone is by the edge with firm lower rib Region absorbs load around, the lower rib by hollow bumps certain variations forward.

German Utility Model G 8126601 discloses a kind of footwear with such sole, and insertion has and points in sole The brush part of bristle afterwards.These bristles are intended to allow to promptly forward launch and by can be to advancing slip after sensing It is dynamic.Without providing bristle corresponding deformation forward, and this deformation be likely to be also cannot.

US patents 3,299,544 disclose a kind of footwear with such sole, the sole it is preceding be provided with sensing with region after Cross rib.Compared with rib, back edge region forms step slightly below.In the case of normal running, rib is directed at platform Contacted with ground before rank, while towards post deflection until the step with contact and limit the further deformation of rib.

DE 29818243 discloses a kind of shoe machine structure with such sole, and the sole has sweptback element, and And when pin contacts to earth, the element is folded along the direction of heel and contacted with remaining sole.

In cannulated unit from the range of the practical application of principle known to WO 03/102430 and wherein described In the range of part, it has proved that these can not deal carefully with all of practice calls, at least can not be with specific described by them Formal layout.In the field of sport footwear, the described specifically-built footwear consistent with the requirement of corresponding sports are supplied to almost appoints The motion of what type, the construction of the sole for particularly all playing an important role in all cases is (even for the corresponding of them Applicability does not have decisive role), this is not accidental.

The content of the invention

It is an object of the invention to how indicate can be with economic side from the outer bottom of type known to WO 03/102430 Formula is better adapted for practice calls, including different types of motion requirement.

It is according to the invention desirable to the tangential deformability of two features required by effect, i.e. one side, on the other hand exists During beyond an at least critical strain different elements are assigned to relative to the rigidity of tangential deformation.Due to can structure independently of one another Think, be sized and manufacture at least one first elements and at least one second elements, thus practice in produce much more design, The possibility of construction and modification, the better off ground than foregoing utilization element (all cannulated elements as is known) is real whereby The now expectation to practice calls is changed, and the hollow component meets two features specified simultaneously.

Also provided substantially in above-mentioned JP 5309001 it is corresponding be divided into it is several can the first element of tangential deformation and several Individual the second firm element.But first element and the second element are arranged separated from one anotherly.First element is located at the In one interior zone, second element is located in the borderline region for surrounding the interior zone.Consequently, it can happen this feelings Condition, i.e. further the so-called interior pin of research or outer pin runner are special hard in borderline region is arranged in detail below Stretched on element, or only have the first element stress when being stretched in sole center, in practice and exist herein floating Dynamic effect, this exactly present invention wishes what is avoided.

Therefore the present invention be applied in the heel area of sole and/or sole region, on the one hand by it is described at least One the first element, the region on the other hand being determined by described at least one second elements are repeated alternately (from heel along longitudinal direction Region to sole region).By these modes, it is ensured that when occurring stretching on heel and/or sole region, always each other Two features are used in sufficiently tight time and spatial relationship.Therefore invention sole characteristic mainly with WO 03/ 102430 correspondence.

Several first elements can be set.The region determined by described at least one first elements can be by an institute State the first element to be formed, it is also possible to formed by several first elements.Accordingly, several second elements can be set.Pass through The region that described at least one second elements determine can be formed by second element respectively, it is also possible to by several Second element is formed.

Identical with from outer bottom known to WO 03/102430, the size of outer bottom of the invention can also be set to so that running When local limit at least one critical strain only reached in maximum weighted region, and only reach temporarily about Maximum stress.At least one critical strain depends on the type of deformation, and outer bottom of the invention cuts at the critical strain Can say it is to be seized to deformability.Deformation is also not necessarily only tangential.In the case of strict vertical or vertically deformation Critical strain can be reached.

Advantageous embodiment of the invention, critical strain only just reaches after tangential and/or vertical deformation path, should Deformation path is optionally even greater than the 50% of the thickness more than the 20% of the deformable thickness of sole.Preferably, institute State tangential deformability should even with vertical variable shape approximately equal.Absolute says, can be equal to approximate 1cm.

For the spring being so sized and vibration damping path, outer bottom of the invention effectively reduces the power occurred during running And stress.Specifically, outer bottom of the invention damping property performance when landing is optimal, because horizontal force main here can edge Running direction soft bending for example by shearing.For the running shoe for being provided with the outer bottom of prior art, even if these footwear are provided with Obvious vertical vibration damping, now as being practically without tangential deformability and high stress peak value occur.During stretching, Outer bottom of the invention absorbs main vertical force due to damping effect again by vertical deformation.Additionally, in the stage outer bottom Had the opposite effect between pin and ground by the different tangential deformation along the different direction of motion, this pin generally in footwear It is obvious that and frequently resulting in worn out socks or even resulting in form bubble in slip.The footwear will not resist the motion, pin During unbending movement the motion is carried out easily with respect to ground.The footwear can make running exempt a large amount of fatigues.On the other hand, exist During leaving the loading completely in the stage, sole of the invention virtually completely loses its vibration damping property.In this stage, no Vibration damping is needed again and vibration damping can only turn into the obstruction effectively left.In the stage is left, it is good that footwear of the invention show as its Seem " hard ".

Shown relative to main stress using the abrasion condition of the outer bottom of a period of time by different runners Very big difference.This is by the distinctive running style different for individual runner.And different running distances is produced Difference is given birth to.For example, short distance runner runs mainly by the front portion of pin, sole region stress is actually only leaned on.On the other hand, Long range runner mainly lands on heel and whole pin is stretched.Here, run with interior pin in so-called outer pin runner Difference is there is also between person.Outer pin runner land in outside, stretched on the perimeter in the middle of pin and in outer pin Left in palm region or left from the region of little toe.It is opposite for interior pin runner situation.And also mixed form, for example exist Outside lands, and is laterally stretched on pin centre and is left from the region of big toe, and vice versa.Sole of the invention can be vertical Deformation and tangential deformation and forwardly and rearwardly deform, and it can be made to be well adapted to these different stress and join With the proper motion of pin.

According to an aspect of the invention, there is provided a kind of heel area and sole region with along longitudinal direction is outer Bottom, the outer bottom being capable of tangentially direction forwardly and rearwardly elastic deformation, and facing only in beyond now deformed zone Ability is substantially firm relative to tangential deformation when boundary deforms, wherein, the outer bottom includes the first element and the second element, wherein Described first elements affect outer bottom elastic deformability tangentially, wherein, second elements affect faces with beyond this The opposite stiffness of tangential deformation of boundary's deformation, and the critical strain in now deformed zone degree, wherein, it is described First element forming region at least one of the heel area of the outer bottom and the sole region region, and Second element forming region at least one of the heel area of the outer bottom and the sole region region, Wherein, the region that the region and second element that first element is formed are formed is along longitudinal direction and transversely repeats Alternately, wherein first element has the non-rotational symmetric shape relative to vertical axis, first element can be along all Direction tangential deformation, and wherein described first element is hollow and thus also can only vertically deform, wherein described first Element has bottom, wherein in the heel area of the outer bottom and/or the sole region, second element is formed Coherent surface, first element is arranged in the coherent surface with distribution method.

According on the other hand, when as viewed from the outer bottom, first element is protruded relative to second element, directly To the acquisition critical strain.

According on the other hand, when beyond the critical strain, first element is being deformed into second element Alignd in the region of the degree.

Specific embodiment

First, one implementation method is described by Fig. 1 a to Fig. 1 c, the implementation method needs not to be preferred embodiment, but logical Crossing the implementation method can well represent the teaching of invention.

Fig. 1 a to Fig. 1 c represent the running shoe 2 equipped with outer bottom of the invention 1.The outer bottom 1 by it is multiple with from WO03/ The first tread contour shape (profilartigen) the hollow component 3a and the element of several platform-likes second being similar to known to 102430 3b is formed.Hollow component 3a can have the height of such as 15mm, and platform-like element 3b can such as height with 10mm.Hollow unit Part 3a and the second element 3b can extend on the whole width of running shoe 2.But they are also arranged to several row adjacent to each other. Platform-like element 3 also can in an annular manner surround single or several hollow component 3a at least in part.Element 3a, 3b for example pass through Bonding is attached to the downside of the intermediate sole 4 of running shoe 1.

Hollow component 3a under the stress produced during running by that the material of elastic deformation can prepare.Second element 3b is with Between sole 4 can also have certain elasticity, however, compared with hollow component 3a, they are substantially firm, particularly with respect to cutting It is firm to deformation.Compared with platform-like element 3b, hollow component 3a is also higher, is downwardly projected from platform-like element 3b.

In meaning defined above, hollow component 3a is formed " by least one first elements in all cases Certain area ".If several hollow component 3a are arranged adjacent to each other, then they can also jointly be classified with the region. The situation of the second element of platform-like 3b is similar to, and platform-like element 3b is formed " by least one second yuan in all cases The certain area of part ".Therefore, along the longitudinal direction of sole, different regions repeats to replace in sole region and heel area. If the second element of platform-like 3b surrounds single or several hollow component 3a in an annular manner at least in part, then in sole table The different region being mixed with each other in addition is arranged on face.

If running shoe 2 for example as shown in Figure 1 b manufacture and when taking a step by as shown in stress arrow P1 with front Power at an angle, then the hollow component 3a for starting only to protrude is contacted and vertical under the elastic buffer of stress with ground 5 Deformation and horizontal distortion.Once hollow component 3a aligns with mutually level adjacent the second element of platform-like 3b, the deformation Just limited by second element 3b.From this, the major part that the element of platform-like second meets with stresses, and due to second yuan The rigidity of part is higher, therefore no longer allows running shoe relative at least any obvious tangential displacement on ground 5.In the stage, run The wearer for walking footwear stands on the ground reliable and stablely.Additionally, as illustrated in figure 1 c, he can also leave again the position of Fig. 1 c so as to Next step is completed, without losing distance herein, because the element of platform-like second is actually unable in the edge during leaving here The direction horizontal distortion of the new stress shown in arrow P2 is to the degree being worth mentioning.

In performance in detail, Fig. 2 a to Fig. 2 c represent a hollow component 3a and platform-like element 3b of Fig. 1 a to Fig. 1 c, And show in fig. 2 a in non-stress and show in figure 2b by tangential stress.In figure 2 c, show Vertical or deformation straight down, can understand from the deformation and know, be also achieved in the case of stress exact vertical above-mentioned The advantage left on stability and in the case where distance is not lost.

For foregoing outer bottom, hollow component 3a allows desired elastic deformability, and platform-like element 3b the opposing party Face determines and limits the possible deformation extent of hollow component 3a, on the other hand ensures that the expectation rigidity of sole is resisted and exceed critical The tangential deformation of deformation.Because the two features are distributed in different elements, exist for these elements bigger The construction free degree.For example, different materials can be used for the first and second elements.And hollow component 3a and WO 03/ 102430 situation is the same must no longer to form fixed frictional connection under possible load, and obvious stress is more on the whole It is small.Most of all, under still noncritical deformation extent, they need not bear all of power weight, and they it On stress by the second element 3b mitigate.If the second element 3b with the surface that contacts have and good grab ground, then be Favourable, wherein can optionally be obtained by the special property on these surfaces grabbing ground.

Hollow component 3a may be characterized as " damper element ", and platform-like element 3b may be characterized as support component.

Above-mentioned implementation method is distinguished by great deformation path, the deformation path such as Fig. 1 a non-stress with The 20% of vertical hang amounts of the hollow component 3a on platform-like element 3b can be for example equivalent to more than between the state of Fig. 1 b, very To more than 50%.Therefore runner's " as on cloud " is spiraled, and always without unstable sensation.

For above-mentioned implementation method, first and/second embodiment 3a, 3b is for example subject to due to tangential force or shearing force Alternate load very high.If strictly adhered to by gluing, then element can be with 4 points of intermediate sole in long-term use From.Here, for a hollow component 3a and two platform-like element 3b, can be for example embedding by part by element 3a and/or 3b Enter and be anchored at being optionally otherwise determined that in intermediate sole 4 and realize improving, as shown in Figure 3.

Fig. 4 represents an implementation method, for hollow component 3a of the implementation method only in intermediate sole 4 shown in insertion. On the other hand, two element 3b are monolithically fabricated and are directly integrally molded to intermediate sole 4 with intermediate sole 4.Additionally, even better , hollow component 3a by tenon connect be anchored in intermediate sole.

Show to be shown in non-stress, figure in the modification of the implementation method of Fig. 4, and Fig. 5 a in Fig. 5 a to Fig. 5 b Shown in stress in 5b.Here hollow component 3a is deeply embedded into intermediate sole 4 so that no longer need at all so as to The element of protrusion second (similar foregoing element 3b) of platform-like is not formed yet.For the construction, " normal " table of intermediate sole 4 Play the function of foregoing second element 3b in face 4.1.Therefore hollow component 3a can be deformed into " recessed ", i.e. be arranged at them " depression " 4.2 in it is at an angle, until they align with the surface 4.1 of intermediate sole, depression 4.2 necessarily be constructed as it is wide enough And width, as shown in Fig. 5 a to Fig. 5 b.

Fig. 6 a to Fig. 6 b represent other modifications of the type of Fig. 5 a to Fig. 5 b, also relatively deep for first element of modification 3a In the embedded intermediate sole 4 in ground, and play above-mentioned second element 3b's for " normal " surface 4.1 of the modification intermediate sole 4 Function.The construction for differing only in the first element 3a of the individual modification of Fig. 6 a to Fig. 6 b.On the left side of Fig. 6 a to Fig. 6 b, point Non- stress is not shown, and the stress in the critical strain stage is respectively illustrated on right side.

For the construction of Fig. 6 a, for example, at an angle can deform or the first element 3a of tangential deformation constitutes the form sold. Here, recess 4.2 can for example be configured to circular.The distance of edge around recess far from pin 3a is identical, and pin 3a is arranged in recess Center, as shown by the two details performance in the bottom of Fig. 6 a.

For the construction of Fig. 6 b, deformable element 3a constitutes the form of tubule, and element 3a is arranged to make its axis hang down Directly in intermediate sole 4.Other constructions and performance are corresponding with Fig. 6 a.

The layer that is made of deformable material or layering 6 are represented in Fig. 7 a to Fig. 7 c, the first element 6a and the at the layer 6 Two element 6b is alternatively formed under non-stress.It is big part that the layer 6 can be integrally formed.Can be along the direction vertical with drawing First element 6a and the second element 6b is set with identical order, so that a structure is formed, for the structure, each first element Surrounded by four the second elements, each second element is equally surrounded by four the first elements.Then again by first and second yuan Part is mixed with each other, as described above.The appropriate component for cutting out size of this layer for example can be fastened under running shoe by bonding The downside of the intermediate sole 4 of the running shoe 2 of side or Fig. 1 a to Fig. 1 c, as shown in Figure 8 a.

First element 6a has the shape of truncated cone, and it is hollow and more slightly higher than element 6b, and element 6b is by solid material Material is constituted and has the shape of truncated cone herein.It is identical with foregoing first element 3a, the first element 6a it is relatively soft and Can forwardly and rearwardly tangential deformation and vertical deformation.Due to their rotational-symmetric form, the first element 6a even can be along institute There is direction tangential deformation in the same way, this is probably extra favourable in the desired aspect of performance that stretches.

By contrast, the second element 6b is substantially firm and feature corresponds to foregoing second element 3b.Element 6a Element 3a and 3b are smaller than with 6b.For example, the total height h1 of the element 6a of layer 6 and first can be 8 to 12mm, preferably 10mm, The height h2 of the second element 6b can be 4 to 8mm, preferably 6mm.In transitional region between the first element and the second element The thickness of layer 6 for example can be 2mm, but the thickness of the bottom of the first element 6a is preferably greater than 2mm.In first element 6a Horizontal range between the center of the heart and the second element 6b for example can be 10 to 20mm, preferably 15mm.

The layer 6 on ground 5 with an angle lateral load is represented in Fig. 7 b.First element 6a vertical deformations under the load, but Special is tangential deformation or horizontal distortion, and no longer protrudes past the second element 6b.Is prevented by the second element 6b The further deformation of one element 6a.The distance of the first element and the second element is preferably selected to have a size that so that the One element 6a can realize shown deformation.Here tangential deformation path is vertical more than possible in its degree before reaching critical strain Deformation path, and for being given above size, at least equal to 5mm.

The layer 6 under vertical load is represented in Fig. 7 c.

The elasticity of the first element 6a is selected such that critical strain occurs under the load of approximate 1kg to 10kg.The value Depending on the quantity of element and the weight of their arrangements (local density), desired damping and runner in sole surface Amount.For the weight (optional dynamic weight) of runner, he at least allows for causing critical strain when leaving.This is for this All possible embodiments of the outer bottom of invention are not always the case, and accordingly the element for element 3a types is also such.It is necessary For less footwear size (runner of lighter in weight) and larger footwear size (the larger runner of weight) selection first The different flexible or different quantity of element 3a/6a.For the first element of element 3a types, in heel area and sole The element that 8 to 15 quantity are distributed on region is typically enough.Because their size is smaller, it usually needs more than 20 First element of 6a types.

The shape and their cloth relative to each other of the first element 6a and the second element 6b of the layer 6 for Fig. 7 a to Fig. 7 c Put, also further construction leeway.For example, the second element 6b can be configured to elongate rib, rule or irregular perpendicular to drawing Platform of shape etc., as shown in Fig. 8 b and Fig. 8 c.Second element 6b can be formed uniformly consistent surface, wherein the first element 6a with Distribution method arrangement, as shown in figure 8d.

Geometric figure shown in Fig. 8 a to Fig. 8 d is, it is evident that the first element 6a and the second element 6b mixed-arrangements, rule Then it is embedded between the second element 6b, and excessive load and abrasion high is protected from by these modes.It is feasible along each Stretch path, the first element and the second element also respectively under tight quarters and time sequencing by these mode stress so that Always by the sensation that two elements determine the performance of sole and run.And first the mixed distribution of element and the second element exist Extend in whole sole region and heel area.

In transitional region between heel and sole, the first element and the second element are not usually required to.Therefore for big Majority application, if layer 6 is generally sufficient in being arranged only at sole region and heel area respectively.Replace vertical relative to footwear To horizontal partition or in addition to the horizontal partition, it is also possible to carry out longitudinally split.Vertical and horizontal point are shown in Fig. 8 c Cut out four layers 6.By these modes, it is also possible to carry out the modification to various sizes of footwear using standard component, as long as these Element only suitably arranges, is especially close together or further away from each other.Finally, can be set in different regions With different layers of different nature.

It is introduced above and by least one first elements or by least one second elements determine region can To be respectively equivalent to the first element 6a and the second element 6b in the implementation method of Fig. 8 a to Fig. 8 d.In the embodiment of Fig. 8 b, Transversely several first element 6a of arrangement close to each other can also be calculated as only one region.On the contrary, in the embodiment of Fig. 8 d Consistent surface 6b can contemplate into and formed by several regions, these regions along longitudinal direction and the first element 6a or with by these The region that element is formed replaces.

May construct by Fig. 9 a to Fig. 9 e describing layer 6 other below.

For the layer 6 shown in Fig. 9 a, the first element 6a is corresponding with the first element 6a of Fig. 7 a to Fig. 7 c.Second element 6b It is provided with square-section.

For the layer 6 shown in Fig. 9 b, the first element 6a is made up of solid material, however, they are in narrower neck It is upper that there is the head for thickening, such that it is able to lateral deformation well and tangential deformation in all directions.

For the implementation method shown in Fig. 9 c and Fig. 9 d, the first element 6a is dimensionally stable and shape by making node 6aa Into, with the second element 6b be connected the film 6ab of elastically deformable type by node 6aa, and by these modes, the first element 6a Can vertical deflection and horizontal deflection to about the same degree.

For the scheme shown in Fig. 9 e, two elasticity delaminations are connected to each other, at least outer layer for it is continuous and except recess it Outer relatively flat.Recess forms the first element 6a together with the approximate relative similar projections of internal layer.And recess is in buffer Form so that the first different element 6a can simultaneously tangential deformation in different directions.Second element 6b by recess with Outer layer between platform or following rib is formed, as shown by Fig. 9 a in embodiment form.

In the range of description above, some feasible implementation methods are only described by way of example.Other are implemented Mode is of course also possible that, and specifically comes from the mixed form of the embodiment.
