Description

The nothing of improvement is with sport footwear

Technical field

The present invention relates generally to footwear, and the footwear of motion and rehabilitation are more particularly related to, it is for specific motion Customized with the professional standards for the wearer for carrying out this motion.

Background technology

Suitable for the physical motion including striding and landing with individual foot --- such as race, jog, walking with vigorous strides away, aerobic forging Refining etc. --- footwear be well-known.Usually, these motion characteristics be foot suspension (suspension) and Land.In such physical motion, individual foot is used as damper when landing, leaves (stepping landing and stride Off supporting member during between) and the spring for promoting from surface such as ground, starting or striding.Although in sport footwear There are many progress in design and construction, but the damage caused during such motion is still universal.Such damage Include the stress fracture and metatarsalgia of calcaneal spur (heal spur), plantar aponeurosis, shin splints and sesamoid bone and caput metatarsale.Can Coming from other flesh skeletal injuries of these physical motions includes rear osteofascial compartment syndrome (posterior compartment Syndrome), shank response syndrome (calf reaction syndrome) and various knees, hip, back and shoulder blade are asked Topic.Continually, the individual mode left that lands and then stride causes these to damage.In many cases, by the footwear of individual dress The inappropriate of class is the significant origin cause of formation.

Then most of pedestrian, racer, canterer are heelstrike pushed off with forefoot later first.So And, during heel lands, tibialis anterior, musculus extensor digitorum longus pedis, Hallux extensors and peroneus tertius make foot be in dorsiflex.The sufficient position Make the natural cushioning ability of foot minimum and frequently result in previously discussed damage.

Landed with heel on the contrary, verified during including such physical motion for striding and leaving and landing, before foot It is maximally effective ground mode that section, which lands,.During forefoot lands, usually, soil fertility while applying to the dynamics of foot Part or forefoot, it includes toe and plantar ball.The inherent flesh of foot and skeletal structure --- including gastrocnemius, musculus soleus, Plantar flesh, tibialis posterior, Hallux musculus flexors, musculus peroneus longus and musculus peroneus brevis --- arch of foot is in suitable posture with when forefoot impacts Play a part of damping spring during support surface.Moreover, it is not initial followed by contact in the case of by forefoot stride from Open and tend to increase efficiency, this be due to do not spend make foot from followed by mobile (roll) to toe trial.Forefoot Ground also reduces the strain to flesh skeletal structure.However, individual general knowledge must also be landed with forefoot consciously.Continually, When they are tired or additionally divert one's attention or be superb, they recover heel and landed.

Landed related damage to heel to overcome, the producer of all kinds sport footwear it is general to heel add the cushions with Some dampings are provided.Although such add the cushions reduces some vibrations, during jog, the impact of pair heel can be according to So in the range of three times of whose body weight or more times.Therefore, the heel or even highly padded can not provide effective suction Receive to reduce the number to individual bulk damage.That is, adding the cushions for reasonable level can not replace the shock mitigation system in individual forefoot.

Penka nothing is with the U.S. Patent number 5,694,706 (1997) of sport footwear, and the nothing enhances various things with sport footwear Forefoot during reason motion lands, inhibits heel to land, enhancing the performance of individual, and does not cause foot experience to come from Stride and leave to the dorsiflex necessarily with potential danger for the last stage that lands.Penka additionally provides such shoes, and it is suitable to From using during the rehabilitation damaged caused by ground mode as heel to toe, and promote to land and stride immediately with forefoot The foot tendency left, without excess tension is placed in into gastrocnemius-musculus soleus and achilles' tendon.

Such footwear has the vamp and many part lower soles to form the internal volume for receiving individual foot.Multi-section Sole is divided to include insole, interlayer sole and outsole.The plantar surface of insole engaging foot portion.Interlayer sole is relatively rigid And the outside of insole is attached to co-extensive and support the plantar surface of foot with least a portion forefoot.According to the invention Different embodiments, the leading portion or proximal segment of outsole can have different thickness --- its at least a portion forefoot and Adjoin rear part below below heel.Leading portion provides ground surface for footwear.It is partly thinner than ground surface afterwards, thus, rear portion Vis-a-vis ground surface is raised the outer surface divided, thus avoids heel from landing.

However, prior art is not specified by being suitable for the depth or thickness and length of the recessed area of Different Individual, it is described Different Individual participates in different types of motion with different technical merits.Defined lack just is causing newly becoming for flesh skeletal injury The reaction of gesture, such as shank, plantar aponeurosis, metatarsalgia and cuboid syndrome.In order to help to prevent these to damage, the recessed area of heel Must clearly it be limited with the depth, length and thickness of footwear sole.

The content of the invention

It is therefore an object of the present invention to the type of the open activity being intended for wearer or motion, individual body bar Nothing based on technical merit of the state and wearer of part in selection activity is with footwear grid (grid).

It is another object of the present invention to strengthen performance of the wearer of such footwear in their selection motion.

The still another object of the present invention is to provide suitable for one kind with various types of damages or the individual rehabilitation of symptom Or previous unavailable embodiment of multi-motion footwear.

According to the present invention, have without the embodiment with footwear the vamp that forms the internal volume for receiving individual foot and Many part soles, the vamp includes toe portion, stage casing and rear part.Many part soles include the plantar surface of engaging foot portion Insole, with being attached to the outside of insole with the interlayer sole of the inner surface coextensive substantially with insole --- the folder Layer sole has outer surface and is attached to the outsole of the outer surface of interlayer sole, and interlayer sole is between interior outsole.Outside Sole have from the near-end of footwear extend to according to the desired use of the footwear select foot below position Part I and from Second adjoining part of the remote or rear part for extending partially into the footwear of selection.The Part I of outsole provides earth's surface for footwear Face, and Part II relative thin compared with Part I, thus for footwear different embodiments suppress after heelstrike and Generally promote the wearer posture or gait suitable in the action for carrying out selecting motion to be included.

Embodiment

As shown in figure 1, according to the present invention footwear 10 include vamp 11, its be attached to many part soles 12 with toe box 13rd, interior bag limits the volume for receiving individual foot with (heel box) 14 and interlude 15 together.Many part soles 12 are wrapped Include insole 16, interlayer sole 17 and outsole 20.The Part I 21 of outsole 20 is limited for engaging by ground, floor etc. The support surface 23 of formation ground surface 22.Behind the backward end (rearward end) 24 of interlayer sole 17 and outsole 20 It is located close to respectively below the interior part for wrapping the interlude 15 with 14 to end 25 and Part I 21.The relative thin of outsole 20 Rear or Part II 28 from backward with 25 extensions to wrap inside below with 14 and limit the recessed surfaces of the exposure below heel 30, when footwear 10 as shown in Figure 1 are in common resting position, heel is raised from support surface.The construction combination ankle-joint and The mechanics of foot makes before the contact support surface 23 of ground surface 22 followed by contact minimum.

Depending on seasonal factor, foot conditions and other standards, vamp 11 as depicted in Figure 1 can have any normal Rule construction.In Fig. 1 embodiment, vamp 11 includes the of substantially standard vamp with braid 31, the braid 31 are used to being fixed on footwear 10 into individual foot 32 (Fig. 2).The ankle-joint 35 that vamp 11 limits individual extends through entering for its Enter opening 34.Material for forming vamp 11 can include, for example, canvas, leather or plastic material.It will be further understood that Although footwear 10 are depicted as into low side Oxford lace loop (low-top tie shoe), vamp can also be with middle side or high side cloth Put manufacture.Bar or other tie up arrangement and can replace braid.Even footwear can be structured as loafer without tying up Arrangement.

With reference to Fig. 2, insole 16 extends through interior bag with 14 and with upper from the front end of toe box 13 or toe end 36 Or inner surface 37 and lower or outer surface 38.The plantar surface 39 of the engaging foot portion 32 of upper surface 37.Lower surface 38 abuts interlayer sole 17 upper surface 40.The upper followed by surface portion of outsole 20 extends backwards over interlayer sole 17.Insole 16 is preferably wrapped The thin layer of relative soft material is included, it is resiliently deformed plantar surface 39 and following surface 40 and surface portion with correspondence above 41 and 42 shape.Soft thin foam with open-pore construction is a kind of example.With reference to Fig. 2, interlayer sole 17 is preferably included Material with some elastic relative rigids, the various cellular foams with the natural of aperture etc. and synthesis.Closed pore Elastic pressure deformable foam is a kind of example.Interlayer sole 17 is below the toe box 13 and interlude 15 of a part, preferably Ground from the front end 43 close to end phalanx 45 to below the region corresponding to calcaneum 50 it is rear to end 24.

Again referring to Fig. 2, outsole 20 footwear 10 it is overall below and can even wind the front-end and back-end of vamp 11 51 and 52.Compared with the combination thickness at backward end 24 and 25, Part II 28 is preferably relatively thin, to avoid fretting wear.Therefore, Walking, race, jog or other similar motions during when passing through the initial contact of ground surface 22, recessed surfaces 30 and support Surface 23 is significantly spaced apart.In addition, Part II 28 is preferably formed by substantially rigid, stiff materials, it is such as non-resilient Rubber or arbitrary various plastic compounds, it does not tend to bending under the associated pressure load of the use with footwear 10.Therefore, Part II 28 supports individual heel 47 by insole 16 securely, while maintaining the interval with support surface 23.Phase therewith Than, including the Part I 21 of ground surface 22 preferably formed by softer, more flexible or elastic material, such as known to other Rubber or plastic compound, to provide more preferable buffering during use, at the same also provide support and durability.

Interval or recess depth D in Fig. 1 of Part II 28 on support surface 23 are based on numerous Considerations. These Considerations include the normal range (NR) that foot is moved, and usually 20 ° of dorsiflex, footwear code, body weight and individual are intended to what is participated in The type of motion, by shod individual distinctive technical merit and any limitation.

According to the present invention, the length L of the outsole 20 used suitable for typical individual during some common motions are participated in and The scope of recess depth D value limits different values.In the various embodiments of the present invention, length L is represented from toe box 13 Front end 36 backward to outsole 20 recess 28 starting point 55 distance.L_TFootwear 10 are represented from the sophisticated to rear of toe-cap 36 With back 57 total length.

As described in Fig. 3 and 4, the length L suitable for giving individual can be from the leading portion 36 of toe box 13 to calcaneum The distance between summit 47 " a " is changed to shorter length b, c, d, e or f, and it corresponds to according to wearer in particular type In motion desired use optimization the end 55 of ground surface 22.The length L of the Part I of outsole 20 is given in Fig. 3 With respect to the total length L of footwear_TSuitable percentage.To put it more simply, not illustrating the footwear between insole 16 and outsole 20 in Fig. 4 Interlayer sole 17.Its skeletal structure is shown when foot is placed in footwear, such as from the inside of foot, to have Show medial arch 59, it includes the connective tissue of metatarsal 61, cubitale 63, navicular bone 65, astragalus 67, calcaneum 50 and correlation body (Fig. 2).

It will be apparent to one skilled in the art that (L=f) is such as being danced in the region of the forefoot of carrying body weight during landing Motion in compare in such as basketball (L=b or c) closer to the front portion of forefoot.In the motion of (L=a or b) of such as walking In, because body weight generally extruding further backs towards the heel of foot during land, so ground surface 22 it is still longer, And the bigger length for ground surface 22 is landed forward by shifting body weight in the mobile period left by striding for foot Buffering is provided to avoid potentially being harmful to heel strike simultaneously.

Again referring to Fig. 3, in different length selections, with reference to the different length of the Part I 22 of outsole 20, for The individual for the motion that participant's body weight is landed with forefoot further along, the length L for ground surface reduces.For professional motion Member, go out as given in Fig. 3 the length of ground surface usually reduce, and construct the recess depth D of footwear with correspondence regulation model The higher-end enclosed.The extra thickness provides some bufferings.Furthermore, relative to beginner, professional athlete ground surface Thickness and corresponding recess depth D are bigger.For example, the embodiment of shoes as the pedestrian of reasonable stalwartness can be given, Wherein length L=b, and the embodiment that shoes as pedestrian less healthy and strong on body will be given, wherein length L=a. Generally, for individual more healthy and stronger on body, recess depth D will tend to thickness larger in given range.For letter Change, Fig. 4 A are not attempt to illustrate between shown different embodiments admissible difference in recess depth D into 4F.

The different length L for ground surface 22 corresponds to the anatomical features of individual foot in footwear, as institute is graphic in Fig. 4 A. For wherein L=a embodiment, the tip of Part I from the toe-cap 36 of outsole extands rearward to the summit 47 of calcaneum 50 Following region.As known in the art, with age, people is intended to the power of their body weight towards foot Followed by it is mobile, this potentially causes or aggravated the damage being previously discussed as.Recessed heel portion helps avoid heel strike And promote more preferable posture.

For constructing the footwear with L=b, when with more nervous rhythm walking or during recreational jog, wear The body weight of person tends to or should more moved forward on foot so that ground surface and is terminated with bigger recess depth D in calcaneum Before 50 summit 47.Due to these increased pressure of motion, it is necessary to which more leg muscles shrink and energy expenditure, and the footwear Wearer is contributed to maintain suitable posture or gait.

Similarly, L=c is worked as, in figure 3 corresponding to more emulative canterer, football player or netman etc. Motion, appropriate mobile the do not include footwear followed by contact of wearer, this is due in movement faster, stronger, to wear The body weight of person is mainly supported by forefoot.Jogged unlike recreational, it usually needs quick on direction to change and typically Avoid flatfoot stance (flat-footed stance).It is recommended here that bigger recess depth D (by thicker ground surface) It is required especially for movement faster, stronger to buffer forefoot.

According to the pattern of pressure involved in increase motion, for L=d, wherein surface termination is landed below astragalus, As shown in Figure 5, more competitively netman or middle-distance race person can from dress with still further reduce Ground surface 22 and the recess depth D footwear that are slightly reduced and be benefited：It provides quicker by the cushion pad of decrement Ground and striding leaves, i.e., the faster reaction time.Although the cushion pad of decrement causes forefoot by bigger from what is landed Pressure, but for for for reaching the enforcer more preferably showed this be acceptable compromise because being inhaled by cushion pad The energy of receipts has slowed down the reaction time, and as mentioned previously, the inner side from metatarsal to calcaneum limited by skeletal structure Arch of foot 59 plays the function of natural spring, and it causes at least in relatively healthy and strong individual in terms of damping and preventing damage, foot Leading portion lands better than heel strike.

As known in the art, the dash footwear particularly for athletics does not almost have any cushion pad, and And only there is contact surface 22 in the front of footwear, it can include the hole that may be inserted into shoe tack.It is shown as implementing in Fig. 4 Mode L=e.Such shoes are intended for the athletics with reasonable robustness, and as explained above, can Land with natural " elasticity " that is landed by using forefoot and quickly and stride to leave and strengthen the performance of wearer.Disease runner Heel should be unfavorable from not in contact with the ground and bulky followed by cushion pad.

In other embodiments, e.g., L=f or g, professional dancer or gymnast by with their body weight at him Plantar ball or even perform or train on the tip of their toe-cap.Fig. 6 illustrates the embodiment of wherein L=f footwear. These are the motions of not necessarily suitable deconditioned sportsman, and in addition to selecting suitable footwear, also take many Precautionary measures are to prevent the damage to many types of these sportsmen.The present invention gives such selection of the sportsman to footwear, It may adapt to training or can be suitable during recovering from some species of damage.

Fig. 5 and 6 extraly illustrates wherein L=d and L=f Example embodiments respectively, and with wherein L=a figure 2 compare, and usually reduce corresponding recess depth D in Fig. 3.It discussed above is the feature of extra embodiment.

, can further customization, according to the footwear of the present invention, and be considered and schemed in Fig. 4 for individual based on various factors The four corner of the value of length L between those of solution.Now it should be understood that the reality of the foot selection for specific individual Border length L (referring to Fig. 3) will be determined by the actual size of the foot of individual, be informed by the professional for trying the footwear on and root Determined according to the preference of wearer.Thus, it is intended that, in the Fig. 3 provided the scope of recess depth D value be it is exemplary and And it is nonrestrictive.
