Description
Background technology
Footwear, especially sport footwear require when strenuous exercise, when for example running or jumping, thereby can prevent potential illeffects for pin provides suitable damping and stability.Footwear industry has been developed various sport footwears, so that maximized the comfort level and the durability of footwear in maximum shock absorption and stability.Regrettably, oppose each other potentially between these targets.For example, can provide the suitable cushioning effect and the footwear of comfort level that enough stability can't be provided.For further promoting the development of sport footwear, be very important to the dynamics of running and the basic understanding of running micromechanism of damage.
The gait cycle of typical walking or running comprises two states: (1) stance phase and (2) swing state.In stance phase, pin contact stayed surface is ground and bear weight for example, and at swing state, the another pin aloft moves and advances.These two states are repeatedly.Run and the gait cycle of walking between difference be that certain some people in the circulation of running skybornely need not to bear any weight, and walking does not have so skyborne point in circulating.
The stance phase of the gait cycle of running can further be divided into three phases: (1) carrying stage, be also referred to as collision and driving phase, or the heel strike stage, (2) mid-stance period, stand and the propulsion phase in the middle of being also referred to as, and the liftoff stage of (3) toe, be also referred to as recovery stage.To the runner of typical " heel is to toe " running type, when the carrying stage originated in heel and contact with the surface of running for the first time, subsequently, it is surperficial that front foot drops to running controlledly.The calcaneal contact first time typically appears at calcaneal back, outer part.In case front foot contact running surface just enters mid-stance period.In mid-stance period, the leg muscle tissue contracts produces power and advances body forward.Heel lift gradually and front foot in metatarsal-phalanges junction bending.In the liftoff stage of toe, pin breaks away from the surface of running and pin becomes vacant state subsequently.
Inward turning (Pronation) action is the regular event of pin, appears at load and mid-stance period in the stance phase of gait cycle.When carrying stage heel strike, the heel of pin rotates and carries out foregoing first the contact with the running surface.In the front foot decline process in carrying stage of stance phase, be called as the abutment release between the pin bone of subtalar joint, to allow the inward turning of pin, three planes (triplane) motion of coordination.Three plane motions of the coordination of pin comprise the action on three planes: (1) abduction, and the front portion of pin turns to the outside and away from runner's travel line in this action; (2) dorsiflex, lift with respect to the rear heel of pin is angled the front portion of pin in this action; And (3) turn up, and the sole of pin outwards changes with respect to the heel of pin in this action.By in conjunction with these three actions, pin goes to inboard or inboard from the outside or the side of pin, cause the inboard (arcuate region) of pin to contact with the running surface, therefore allow pin adaptation running surface and some loading forces are transferred to the surface of running, thus the injured risk of the stance phase of minimizing in running.Remain the inward turning position of pin in mid-stance period.
The action of turning one's hand over is typical in after the inward turning action.When health moves forward by pin, subtalar joint locks.This just allows oppositely to appear at mid-stance period in the incident that the carrying stage occurs.The action of turning one's hand over is three planar gesture of the coordination of pin, and it comprises the action on three planes: (1) closes up action, and the locking of subtalar joint allows pin inwardly to turn to travel line in this action; (2) plantar flexed, front foot is bent downwardly with respect to heel in this action; And turn in (3), the sole of pin inwardly changes with respect to heel in this action.In conjunction with these three actions, pin is continuous goes to toe forward.In thenar (ball) and action that toe contacts, before toe just began built on stilts, pin outwards rotated.These three actions in conjunction with allowing pin to be transformed into the lever of a rigidity from a mobilizable joint, and that this pushes ahead health just is necessary.Pin kept during built on stilts turning one's hand between the step.
Although the inward turning action is a normal action, and be considered to an important and healthy reaction to a large amount of strong impacts that put on pin, biomethanics shows, extra inward turning and high inward turning speed have caused runner or other sportsmen multiple injury at ankle-joint, knee and hip.The sole of many prior aries is designed to control inward turning and turns one's hand over.But, along with the stability that improves sole with the lateral movement amount of control pin to prevent excessive inward turning, the damping performance that is used to reduce the impact influence on the pin can reduce usually.Therefore, when the design sole, footwear industry is being sought the suitable balance between stability and the damping performance always.
For example, authorize people's such as Lyden U.S. Patent No. 5,625,964, a kind of sport footwear is disclosed, its sole has the rear foot shock zone that splits from remaining heel region by a flexible lining, and its permission couples together shock zone in the process of the initial heel strike of runner.Being provided for of this flexible lining marks off the rear foot that can reflect the most running style from the heel to the toe among the runner crowd and impacts band.Except allowing rear foot shock zone around flexible lining connects, sole is in conjunction with damper element, comprise an elastic bag, provide discrepant shock absorbing characteristics in calcaneal different piece, weakening the application of force and the impact relevant, and in the stage subsequently of gait cycle, can not reduce the stability of footwear with heel strike.Flexible lining can form by the whole bag of tricks, comprises dark groove, the soft relatively part of Rou Ruan midsole material lining, and the fluid cell of segmentation relatively.
Existing in the market sport footwear all is typical sandwich construction, comprises the footwear outer bottom, the end in midsole and the footwear.The footwear outer bottom is usually by high-abrasive material such as rubber bearing, and the footwear outer bottom is the part that contacts with ground in the sole.Midsole is the part at the end in footwear outer bottom and footwear, and it comprises that typically compressible material such as ethylene vinyl acetate (EVA) foam comes damping.The end is and the contacted part of wearer's pin that it generally includes the comfort level that a soft pad improves footwear in the footwear.
The durability of midsole also is an important goal of sole design.The foamed material that is usually used in midsole for example eva foam has limited service life and is tending towards fracture along with the time.In age in the past, the interchangeable midsole designs that does not rely on or seldom depend on foamed material is developed.
For example, all authorize the U.S. Patent No.s 4,536,974 of giving Eli Chen, No.4,611,412, No.4,754,559 and No.4,573,021, described and had many midsoles rib.All ribs have the arc or raised surface of at least one length of extending rib.When weight is applied on the sole, each bar rib begins deflection, and the compression point place at these ribs is adjacent to each other up to adjacent rib.Insert can be positioned between the contiguous a pair of rib filling the space between the adjacent rib, thereby suppresses the deflection of rib.Compressible bridging element can be arranged between a pair of rib, to avoid by the lasting contact of the rib of phase adjacency pair and release and the noise that produces.
People's such as Simon Lythi U.S. Patent No. 5,461,800 and No.5 given in mandate, and 822,886, the Unitarily molded midsole with tubular suspension members has been described.Tubular suspension members is worked as spring, and has for what special applications designed and pass through to select pipe range, the thickness of tube wall or tube material intensity and definite spring constant.Preferably, midsole is by artificial rubber HYTREL for example

The specific embodiment
By description, can better understand the present invention below in conjunction with the preferred embodiment of accompanying drawing.It will be apparent to those skilled in the art that described embodiments of the invention only are exemplary and descriptive, rather than restrictive.Remove and specify that all disclosed features all can be replaced by the replaceable feature with same or similar purpose in this specification.Therefore, should be considered as dropping in the scope of the present invention and equivalent thereof to its various other embodiments of making amendment.
Attached Fig. 1 and 2 has described the exemplary embodiment of midsole element according to an aspect of the present invention.Midsole element 1 comprises: medial element 2 and lateral element 3.This medial element comprises top medial 4, bottom medial 5, and be arranged between top and the bottom medial 4,5 in order to support, top interior plate 4 and make it a plurality of medial strut members 6 away from bottom medial one segment distance.Lateral element 3 comprises top lateral plate 7, soffit panel 8, and be arranged between top and the soffit panel 7,8 in order to support, top outer panel 7 and make it a plurality of lateral strut members 9 away from soffit panel 8 one segment distances; At least a portion of wherein a plurality of lateral strut members 9 is with an angle (θ
1) be installed at least a portion of a plurality of medial strut members 6.Angle θ
1Be arranged on greater than 0 degree less than 180 degree, preferred about 5 to about 120 degree, preferred about 10 to 90 degree, and optimum about 15 to about 75 degree.This direction design provides anisotropic flexibility and rigidity to sole respectively on the vertical and horizontal of footwear.
In the embodiments of the invention shown in Fig. 1 and 2, midsole element 1 has a cavity 10 between medial element 2 and lateral element 3.Cavity 10 has lateral edges 11 and inward flange 12.Lateral strut members 9 is vertical with the lateral edges 11 of cavity, and the part of medial strut members 6 is vertical with the inward flange 12 of cavity.Cavity separates medial element 2 and lateral element 3, and makes that midsole element 11 is more soft.Soft midsole allows footwear crooked under impacting, and therefore reduces to put on the moment arm (lever) at the impulsive force center of footwear.The reducing of moment arm reduced the moment of torsion around the subtalar joint, therefore reduced interior spinor at the subtalar joint place, and reduced the speed of inward turning, thereby increased the stability of footwear, kept best damping by the lateral element 3 of midsole 1 simultaneously by medial element 2.
The inboard can be connected with lateral element 2,3.For example, inboard and lateral element 2,3 can be by Unitarily molded and link to each other in their rear end as shown in Figure 4.Inboard and lateral element can further use at least one bridging element 13 between top medial 4 and top lateral plate 7 to connect.Can estimate that described one or more bridging elements 13 can be present between bottom medial 5 and the soffit panel 8.
C shape support member than other shapes for example the support member of S shape support member, wavy support member, allotment support member and inclination be superior in shock absorbing characteristics.Although do not wish to be bound by any special theory and since S shape structure therein the heart have a flex point, and C shape structure does not have flex point, so C shape has different drag sag curve characteristics with S shape structure.This has just caused the characteristic of S shape structure, and for example dynamic range and foresight obviously are different from C shape support member.For example, because the stressed sag curve of C shape structure is more linear with respect to S shape structure, thereby C shape structure has bigger dynamic range than S shape structure.The stressed sag curve of S shape support member has shown that the amount of deflection in the initial period is consistent with rigidity and subsequent stage.In addition, S shape structure lacks foresight on performance, and this is because S shape structure has three bending areas, and C shape structure only has a bending area.Therefore, the uniformity of material in S shape support member than more important in the C shape support member.Wavy support member has more bending areas than S shape support member, and therefore has all defect of the S shape laminated structure of discussing all fronts.Straight line and slanted struts do not provide controllable distortion, and therefore the reaction of their impact power is difficult to precognition.For example, depend on the point of application, support member can be at the top of this support member, centre or bottom bend.
As shown in Figure 6, when sole sandwich component was in reversed position, the lateral strut members 9 that is arranged between top lateral plate 7 and the soffit panel 8 also was a C shape.C shape support member can have various deformation.Accompanying drawing 7-13 has described several examples.
The thickness of support member is extremely about 15mm of about 0.5mm, and preferably about 1mm is about 6mm extremely, and is more preferably about 2mm to about 5mm.The wall thickness of support member can be identical or different with inboard and lateral element, to control the inboard inward turning and the damping in the outside.In addition, for application and other design according to footwear of each support member, its horizontal and vertical wall thickness can be different, to regulate damping.For example, the wall thickness that can predict support member can reduce from the lateral edges to the inward flange gradually.The structure of support member can be made amendment by those skilled in the art, with the performance of optimizing midsole be that special applications and individual carry out customized.
Material inboard and lateral element can be an elastomeric material, for example engineering resin, or any durable elastomeric material.Top board, support member and base plate inboard and lateral element can be selected from following exemplary materials independently, certainly other materials that are suitable for also are predictable: thermoplastic polyurethane (TPU), polyester-TPU, polyethers-TPU, polyester-polyethers-TPU, polyvinyl chloride, polyester, thermoplasticity ethyl-vinyl acetate, styrene-butadiene-this ethene can be purchased in trade mark Pebax
