Description
The present invention relates to a kind of footwear sole construction of sport footwear, it comprises outer bottom and the interlayer of being made up of mass part, and this interlayer is flexible and supports foot in running.
The function of running shoes is the behavior in order to help to run on the one hand, like this runner's the economy as much as possible of advancing; On the other hand, be in order to protect foot to avoid the pressure that from run, is subjected to.In order to reach these functions, having developed its various sole-shaped becomes flexible to reduce foot pressure and to make the more effective sport footwear of running.
Muscle alternately stretches and shrinks in the running process.The paces of running comprise leap stage and driving phase.Muscle is movable in advance in the leap stage, prepares for the impact at the pin of bottom, acts directly on the bottom at big reaction force of this stage.Be stored in their structure in pre-movable muscle stretching, extension (eccentric phase) of assault phase and the elastic energy that can utilize in the concentric stage after following stretching, extension closely.Produce decision direction of motion by his/her muscular work and in the strength of the acceleration of his/her center of gravity of leap stage (motion can) the contact phase runner.Bottom the institute that the runner produces is delivered to by the stayed surface that is formed by running shoes effectively.According to Newton's third law, the rightabout reaction force of equal number acts directly on the runner from the bottom.Initial in assault phase, this power passes to the tendon association that causes Lik-Sang to become to increase by bone and tendon.
Running shoes are as having served as the key player the transmitter that Lik-Sang becomes between bottom and the runner that runs.The geometry of footwear and its rigidity, flex capability can influence the operation of Adjustment System, see that from the visual angle of the nature and the motion of economy it is very important.In addition, the geometry of footwear directly influences the size of the arm of force and passes through this, the demand that influence power generates.
From patent US4,757, the footwear sole construction of known a kind of sport footwear among the 620Z, this footwear sole construction comprise buffering and the supporting construction that is arranged between wear-resisting sole and the intermediate layer.This buffering and supporting construction comprise: the flexible toe portion that extends to ball area basically from the sole top; Mode with the picture chock is also extended the elasticity heel portion on heel area at least from the sole rear part edge towards sole front end convergent; And basically from the sole rear part edge extend to ball area or be installed in be suitable for heel and heel portion on the arch of foot zone of matching on main component, this main component is harder and firm than described heel portion and toe portion basically.Such footwear sole construction has accepted to act directly in the landing period of pin the collision impact of runner's heel effectively.In the recovery phase of foot (rolling phase), the footwear sole construction arch support, this has reduced the pressure that directly acts on pin.In foot's Take-off Stage, eliminated the unnecessary slip of footwear.
One of effect of running shoes is that the protection pin avoids incorrect posture, as excessive inward turning (ankle inwardly rotates too many) or outer change (posture relative with inward turning).Known running shoes often use the excessive inward turning protection of feet in the running process.Yet because this support has hindered the proper motion of pin, therefore too many support can cause fatigue damage.
The better footwear sole construction that the purpose of this invention is to provide running shoes, it promotes nature and economic motion, the appearance of prevention fatigue damage.
In order to reach this purpose and those purposes that occurs subsequently, in the introduction of the characteristic of claim 1, describe according to its feature of footwear sole construction of the present invention.
The interlayer of the footwear sole construction that this is new is made up of three parts at least, and this three part is: along the flexible main element of whole sole length extension; Extend to the flexible heel absorption element of heel area; And be clipped between main element and the heel absorption element and extend to the support component of ball area from heel area.This support component is made less than the flexible material of main element and heel absorption element by flexibility, and wherein this support component is clipped between main element and the heel absorption element.In addition, the structure of foot's bone and taken into account during at the design support component in the proper motion path of the different phase of running paces.
In the preferred embodiments of the present invention, support component comprises the heel portion that is essentially tabular and is shaped anteriorly that they are separated from each other by the support ridge from the substantial lateral of the lower surface projection of support component.Preferably, this support component comprises two projectioies, the wherein inward flange setting of the first projection next-door neighbour footwear, and second projection that is provided with than the outward flange that is close to footwear is high, has the zone that support ridge is lower than projection between described first and second projectioies.Studies show that such supporting construction supports foot effectively in the different phase of paces, and the proper motion path of the restrict foot of exceeding.
In one embodiment of the present of invention, the upper surface of support component is equipped with the depression that carbon fiber board is installed, and its effect is the torsional rigid that increases support component.This carbon fiber board of making by the mode that is higher than its vertical rigidity with its lateral stiffness is realized.Preferably, the extension of carbon fiber board below sole, at the place, outer peripheral side of footwear will be distal to the extension at the place, side of the inward flange of footwear.The rear portion of carbon fiber board can be equipped with the star mouth, and this star mouth has improved the flexibility of the holding components that is equipped with this carbon fiber board in the heel impact process.
Can further equip the hourglass shape ball absorption element in the depression at the sole place that is installed in the main element according to footwear sole construction of the present invention.This ball absorption element is by more there is flexible material to make than main element.It is general mode that absorption only is set at the middle part of ball area, but in fact, considers that from the anatomy of pin this is the most problematic place.If absorption piece is only at the middle part of ball area, the long bone of toe will be compressed in the external zones of footwear, be to cause one of major reason of the problem in the foot district as this compression of repeating motion.As everyone knows, crest pressure appears at the metatarsal terminal edge.When absorption piece is a hourglass shape, load pressure is distributed in the whole ball area more fifty-fifty, and this has realized effectively and driven forwards the take-off of sole.
The footwear sole construction of the footwear that the present invention relates to implement in a new way, foot is followed and supported to this footwear sole construction, kept the prerequisite of the nature and the motion of economy like this.In the improvement of new footwear sole construction, anatomy and Biomechanical factor are considered as starting point.The geometry of footwear is especially paid attention in the improvement of this product, has played the part of the key player because have been found that organization plan as the conveyer that Lik-Sang becomes between bottom and the runner of running.
Carried out measurement series in the biomechanics experiment chamber of Jyv skyl university, this breadboard purpose is to use the research of biomechanical approach to analyze the operation of new footwear sole construction.With market on the comparison of two running shoes in, find that footwear of the present invention are to running technical ability and not influence of muscle activity simulation.Based on this, the flex capability of geometry and impact absorption and footwear is depended in the change that can suppose reaction force between the different footwear and force value.
When research pressure loading when acting directly on foot, find to use new running shoes, the load value of heel shock absorption is in jogging and hurrying up during all than the footwear motion of using reference low 34%.When the pressure loading on the detection ball area, can find the force value that distributes and more be evenly distributed than with reference to footwear in the sole uptake zone of new running shoes.All these differences all have statistical significance.The sole uptake zone of new footwear meets anatomical structure setting (end of metatarsal).In sole Take-off Stage (promotion stage), in new footwear, found the minimum mean value and the maximum of power, this show travel direction keep unusual level.This from the size of vertical motive force also as can be seen, the vertical motive force of new footwear is minimum and has statistical significance.
Transition from the heel impact stage to the stage of promotion is called " hunt effect (rollingeffect) ".Hunt effect should be quick and balance.Footwear should support and follow the proper motion of pin.Discover that new running shoes can be implemented to promotion stage hunt effect the most fast, and at the average pressure center when natural route in foot areas moves hunt effect be balance.Outward flange or the inward flange big transfer (too many outer change or corresponding inward turning) of pressure toward pin do not appear.Average and fast hunt effect be that effective Lik-Sang becomes with the paces of economy to have created prerequisite.
In the research of the economic virtue of running, done interesting and important extra observation, the people's ratio that uses new footwear to run in this observation uses the people with reference to footwear, and heartbeat is on average lacked 4 times under normal loading, and oxygen demand on average lacks 4%.This phenomenon can explain by the result that the observation stressed plate is analyzed, according to this result, use new running shoes directly forward the generation of power quite be higher than use with reference to footwear.This result has clearly show that the economic virtue of running can significantly improve by running shoes, and by running shoes, can reduce the energy consumption in the running process.The variation that observes in the research has influenced the final result achievement that the long-distance runner obtains fatefully, as in marathon.
To describe the present invention by accompanying drawing below; Yet the details of accompanying drawing is not meant to limit the present invention.

Fig. 1 shows the sport footwear that is equipped with footwear sole construction according to of the present invention.This footwear sole construction comprises outer bottom 11 and by mass part 12,13,14,16,21,23 interlayers of forming 10, this interlayer 10 be shaped and structure so that it is flexible, and in the running process feet when needed.Outer bottom 11 is made up of heel portion and sole (ball) portion.
Interlayer 10 comprises: the flexible main element 12 that extends along the whole length of footwear; Extend to the flexible heel absorption element 13 of heel area; And be installed in the support component 14 that the heel area on the arch of foot between the said two devices extends to ball area.This support component 14 is by making than main element 12 and heel absorption element 13 harder materials, and is configured as the proper motion of supporting and following pin in the running process.Except these three major parts, interlayer 10 also comprises ball absorption element 16, carbon fiber board 21 and arch support 23.
The main element 12 that is shown in further detail among Fig. 2 is become by the polymeric material that favorable elasticity is provided for footwear.At the upper surface of main element 12, at the sole place one recess 15 is arranged, hourglass shape ball absorption element 16 is installed in the recess 15.Ball absorption element 16 is made by the elasticity special material that recovers its original state after finishing from load immediately.The hourglass shape of ball absorption element 16 follows the anatomical structure of ball area (end of metatarsal) closely, its possible absorption that offers the best under this situation.Simultaneously, it helps to guide kinetic energy forward.It can also be seen that from Fig. 2, this absorption piece 16 in the side of the inner edge I E of pin the width of the side of big toe (perhaps) greater than width in the side of the outward flange OE of pin.
Heel absorption element 13 is plate-like pieces, and its edge shaping in the side of arch of foot is to be installed in the special shape of support component 14.Have the depression as the known way (not shown) in the centre of the lower surface of heel absorption element 13, this depression has been improved the flexible of in heel impact process footwear and helped the impact that distributes in wideer zone.The contact phase of running paces begin to occur impact peak value clearly, therefore make main body bear the moment top load, this is concerning the generation of spraining.Because new midsole structure 10 is distributed in wideer zone from the pressure that impacts.As can be known, adopt according to footwear of the present invention from research, the load value of heel impact is than using with reference to low 34% of footwear.
Heel absorption element 13 can be from making with main element 12 identical or corresponding materials.The polymeric material that is fit to is, for example, and the ethane-acetic acid ethyenyl ester (ethylvinylacetate) of hardness in 50-55 Shore C (Shore C) hardness range.
Can see the shape of the lower surface of support component 14 in more detail from Fig. 6 and 7 of the bottom view that shows support component 14.This support component 14 comprises tabular heel portion 17 and partly extends to the shaping front portion 18 of ball area.This heel portion 17 and anterior 18 is separated from each other from the outstanding horizontal support ridge 19 of the lower surface of support component 14, all takes the shaping that designs this support ridge 19 into account with the bone of pin with at the motion path of the different phase of running.Support ridge 19 comprises that two protrude 19a and 19b, protrudes between 19a and the 19b at these two to have the regional 19c that is lower than them.The inner edge I E of the contiguous footwear of the first protruding 19a, and the outward flange OE of the contiguous footwear of another lower projection 19b.As the height estimation of the support ridge of some types, we can say that if the thickness of the support component 14 in the slab region of heel portion 17 is H, then support ridge 19 is as follows in the corresponding height at different piece place: be 2.2-2.5 times of H at protruding 19a place; At protruding 19b place be H 1.7-1.9 doubly; At the lowermost extent 19c place of support ridge 19 be H 1.2-1.5 doubly.
Fig. 5 shows the shallow depression 20 in the upper surface that is formed on support component 14.This depression 20 be used to hold by the carbon fiber manufacturing, its function is the plate 21 that increases support component 14 torsional rigids.The top plan view of carbon fiber board 21 itself is shown in Figure 3, and side view is shown in Figure 4.The fiber of carbon fiber board 21 is through directed, and the lateral stiffness of this model 21 is higher than its vertical rigidity.Carbon fiber board 21 allows to occur at driving phase the inside rotation (inward turning) of pin, but prevents undue inside rotation (crossing inward turning).This plate 21 also keeps its flexibility in the pressure that takes place in the vertical changes, natural route is followed in the Center of Pressure of paces in this case.
The carbon fiber board 21 that note that the torsional rigid that increases footwear sole construction is annexes of choosing wantonly, does not need this carbon fiber board 21 when not needing the protection of inward turning in the footwear.Therefore, according to running shoes of the present invention also not needs carbon fiber board 21 make.
In addition, the footwear sole construction of footwear is equipped with its function for improving the arch support 23 of the direction of step in its proper motion path.This arch support 23 is preferably made by the PVC plastics, and it is shaped so that it guides movement to the outward flange of pin.
Use elastomeric material can resist wearing and tearing admirably in the heel portion of outer bottom 11, and therefore,, prolonged the service life of footwear owing to this part.Elastomeric material in the ball area is flexible, can realize in this case effectively promoting the stage.The hardness of the elastomeric material below the heel is 60 ± 3 Shore A (Shore A).Be that wherein rubber hardness is approximately the zone of 65 Shore A below sole.
Many improvement of the present invention all may drop in the scope of the present invention's design that limits as following claim.
