Description

Sole and footwear with additional heelpiece with this sole

Technical area

The present invention relates to a kind of footwear, refer more particularly to the convenience and the stability of four steps that can improve walking, have the sole of durable construction simultaneously and have the footwear of this sole.

Background technology

The inscape of pin can be brought into play its function for making pin, and constitute basic fixed structure under standing state and mobile status, and under each different conditions, forms several kinds of typing forms and structure through mutual combination.

In gait processes, the form of pin is different in each step, and according to the form that pin forms in walking, gait processes is divided into four steps substantially.With the action is benchmark, is divided into heelstrike, whole pin land, lift heel and with four steps such as forefoot promotions, carry out walking movement thereby pin carries out these four steps repeatedly.

At first; In the heel of the first step of walking lands; The pin that carries out common walking forms dorsiflexion of foot (Dorsiflexion) when heel lands; In whole pin of second step of walking landed, the pin of walking formed that whole pin lands and the sole of the foot that ankle stretches is bent (Plantarflexion) usually.

Lifting in the heel of third step, thereby ankle more extends the sole of the foot bend to be strengthened, and has formed the form that the articular portion that connects metatarsal head and the proximal phalanx that constitutes the toe first segment is bent upwards.During the forward foot in a step of the 4th step pushes away forward; The toe formation sole of the foot as toe section is bent, angled metatarsal of curved and proximal phalanx stretching, extension each other in third step, and toe is with the ground pusher; Go to next first step afterwards, form dorsiflexion of foot and the pin built on stilts.

For the slyness of walking in this each step is carried out, the inscape of pin is forming several kinds of forms of finalizing the design in the relation each other.When realizing owing to this form of certain reason is abnormal; The walking meeting is non-efficient, and on the one hand, the each several part of pin receives excessive pressure or power and damage or deformity take place; On the other hand, the necessary part of pin can not fully be used and when producing the pin deformity function of pin reduce.

Footwear be the protection pin avoid coming from the outside hot or cold, with the damage that contacting of exterior object causes, play the effect of the suffered impact of pin when relax moving again, but the also freedom activity of restrict foot possibly bring adverse influence to pin.

When the sole of existing footwear for protection foot and possess the durability of footwear self and when using hard material with certain mechanical strength from ground; Under halted state, do not have big problem; But when walking or running; The free activity of hard material meeting restrict foot need apply necessary above dynamics or make pin can't form the walking form of necessity.Particularly, the third step of walking promptly lifts in the heel, has hindered to form the abundant distortion that the sole of the foot is bent required pin.As stated, when the distortion of pin was insufficient in third step, pin was difficult to put aside the elasticity of muscle and makes toe section can't in ensuing the 4th step, push ground, and the result can produce the problem of the efficiency difference of walking.

On the contrary, its durability variation when sole uses too soft material, and also variation of the stability of pin.According to different materials, might cause expense to increase in order to reach durability.

Existing product shoes; When running or walking, the impact when landing in order to reduce is generally used in the bottom surface of footwear to absorb the elastomeric material that impacts usefulness; But use to absorb impact with the position of elastomeric material differently, cause easily when pin lands from the problem of the center unstability increase to the left and right of pin.And the footwear that air chamber are set and utilize compression of air to cushion in the middle of the heel, the uneven increasing about pin when heel lands is so cause the damage of ankle easily.

Summary of the invention

Technical task

The objective of the invention is to; Solve or alleviate the problem of the above-mentioned existing footwear in the walking, its purpose is to provide a kind of sole and footwear, the third step in the walking that is made up of four steps; Make calcaneal lifting become enough and easy, thereby improve the walking convenience.

In addition, the object of the invention is, a kind of sole and the footwear that use this sole that can improve the durability of the middle foot part that receives big pressure is provided.

In addition, the object of the invention is, provides a kind of the left and right sides balance of pin and the distribution of strength are become evenly, thereby improve stable sole and footwear.

In order to achieve the above object, sole of the present invention is characterized in that, has: main body, and it forms, and is thinner than other parts corresponding to the part of the metatarsal portion of pin; Additional heelpiece, it is independent of aforementioned body, and is arranged on the part corresponding to above-mentioned metatarsal portion.

Among the present invention; Above-mentioned additional heelpiece is formed; With the human body center is benchmark; Longer and extend and be arranged to the middle foot area of more leaning on the rear than above-mentioned metatarsal portion than pin inside part corresponding to the outside of foot in the part of metatarsal portion part, and when the pin longitudinal axis was cut and analyse and observe, the rear portion of above-mentioned additional heelpiece was thicker than the front portion.

Among the present invention, be formed with heel corresponding to calcaneal back foot part in the sole, this heel can form, the inboard thomas' heel (Thomas heel) more outstanding than the outside when being benchmark with the human body center.At this moment, heel can also be that the mid-depth position of rear end is provided with the heel buffering shoe of chock shape elastic portion with (SACH heel).

Among the present invention; Particularly; In the narrow footwear such as women's high-heeled shoes of heel, above-mentioned additional heelpiece extends and is set to the middle foot area of more leaning on the rear than metatarsal portion, on the vertical section of cutting along the pin longitudinal axis; The rear portion of above-mentioned additional heelpiece is thicker than the front portion; Interior lateral direction width be formed with the part that contacts with ground corresponding to calcaneal back foot part is the heel below the 3cm, in above-mentioned additional heelpiece, extends the part of foot area in being arranged to, and can be formed with from stability column inboard and that the outside is outstanding.

Among the present invention, the medial surface of the thin part of sole, the particularly part corresponding to metatarsal head can be provided with softness and the strong elastomeric material of screen resilience.Elastomeric material can be rubber-like rubber, ethylene vinyl acetate (E.A.V:Ethylene Vinyl Acetate) foam or polyurethane resin etc.; So long as thereby the material that when being under pressure, wraps up the metatarsal head periphery than easier contraction on every side all can use.Can also use shape-memory material.When being under pressure, this part is supported that by elastomeric material so compare than the characteristic point of metatarsal head periphery, pressure can be dispersed to the whole periphery that is provided with elastomeric material, can also play the effect of impacting that relaxes corresponding to the part of metatarsal head.

Among the present invention, additional heelpiece can be made up of hard material, to have durability, can also form deep trouth so that metatarsal curved easily bending on first watch at the pin cross direction.That is, have a plurality of grooves that form along left and right directions, lifting calcaneal step, because the thinner thickness of groove, curved easily bending, thus also bend when thicker corresponding to the sole of middle foot in the whole footwear than other part is more curved.

On the other hand, among the present invention, at the additional heelpiece at the rear portion of metatarsal portion, also possessing with the pin cross direction is the metatarsal horizontal stripe of length direction.Metatarsal portion rear area in the additional heelpiece is thicker than metatarsal portion front region.At this moment, under the state of installing in the mounting groove on the part of metatarsal horizontal stripe on be formed at additional heelpiece, be provided with in the part of metatarsal horizontal stripe, more project upwards above the peripheral sole of top ratio of metatarsal horizontal stripe, or top consistent with additional heelpiece.

Footwear of the present invention is characterized in that, utilize above-mentioned sole manufacturing.

According to the present invention, in the third step of the walking that constitutes by four steps, make and lift heel and become fully and easily, both improved the convenience of walking, can also improve the durability of the metatarsal portion part that receives big pressure simultaneously.

According to the present invention, the left and right sides balance of the pin during walking and dynamics are distributed the equilibrium that becomes, thereby have improved stability.

Among the present invention, the form of the pin during walking in four steps is more natural, has both improved the efficiency of walking, the pathology that can also prevent walking to bring.

The specific embodiment

Following with reference to figure, specify the present invention through embodiment.

Fig. 1 is the upward view of sole in expression one embodiment of the invention.

See that from anatomy heel is according to Chopart's joint (Chopart ' s joint) and tarsometatarsal joints (Lisfranc ' s), divide into three parts such as front foot portion, middle foot and back foot part.But sole is that front foot portion is divided into toe section and phalanx portion according to metacarpophalangeal joints (MP joint), and like this, sole is divided into the metatarsal portion 120 of back foot part 140, middle foot 130, front foot portion and 110 4 positions of toe section of front foot portion.

For facility, the line that the sole basis is vertical with the pin longitudinal axis is divided into four parts simply from the place ahead to the rear in the present embodiment.In the sole, the part that is equivalent to metatarsal portion 120 of the front foot portion of pin is thinner than other parts.This thin part uses mould molding to be thin shape usually in the step that forms sole originally, but comprises the situation of afterwards removing counterpart.Be provided with heel 141 in the back foot part.

Very unfertile land is formed on and is provided with additional heelpiece 150 in the part of metatarsal portion 120 in the sole main body.Additional heelpiece 150 usefulness stickers are bonded in main body.Additional heelpiece is general to be used and the main body material different.That is, additional heelpiece can constitute different with main part on material and form.Metatarsal portion has the part that pressure is concentrated in the walking third step, so it is good that additional heelpiece uses the solid material that is difficult for by the pressure abrasion as far as possible.Just; For be easy to carry out four in the walking step third step, be calcaneal lifting; In the bottom surface of additional heelpiece with the vertical groove 153 that formed (left and right sides width of pin) with the pin longitudinal axis, thereby with the sole main body relatively, it is also curved easily in the wrong to apply big strength.Third step in four walking steps, promptly lift in the heel step, bend the form of deepening according to the pin sole of the foot and outstanding when crooked downwards when additional heelpiece, groove 153 forms the thin part of additional heelpiece 150, and additional heelpiece is curved easily bends thereby make.

Fig. 2 is a upward view of having represented the sole of another embodiment of the present invention.

Fig. 3 is to the sole among Fig. 2 embodiment, representes when the face parallel with the pin longitudinal axis cuts the cutaway view of longitudinal direction section.

With reference to Fig. 2 and Fig. 3, sole is as shown in Figure 3 in the present embodiment, and the main body 90 (main body of sole is 2 layers here, and illustrated 2 layers of structure can be made up of sole and middle level or sole and nexine) that is divided into 2 layers by thickness direction (above-below direction) forms.On the upper strata, padded coaming or elastomeric material 60 are set substantially near the metatarsal head of metatarsal portion.Can use rubber or E.V.A foam, polyurethane resin etc. as elastomeric material 60.

Lower floor is similar with the embodiment like Fig. 1, in metatarsal portion, has to form very thin part, in this thin part, is provided with additional heelpiece 50.The additional heelpiece 50 main stickers that use are bonded on the main body 90.

Additional heelpiece 50 is along the pin longitudinal axis shown in the AA ' of Fig. 2, and when blocking with longitudinal direction, the rear portion is thicker than the front portion, to keeping thick form near the end.Section substantially with the truncation surface of aircraft wing show streamlined similar, have outstanding downwards form.Therefore, additional heelpiece forms the shaped form bottom surface of front foot portion metatarsal portion, so claim forward foot in a step keel (forefoot rocker).

In the present embodiment, with Fig. 2 same level on see that additional heelpiece 50 outsides are longer than the inboard.When simply being divided into four parts such as the toe section of front foot portion, the metatarsal portion of front foot portion, middle foot, back foot part, the place ahead of foot 30 during the outside rearward end 51 of additional heelpiece 50 parts expand to from metatarsal portion 20.

On the one hand, comprise in the calcaneal back foot part 40, be provided with heel at sole.Heel has the extension 41 that the part of middle foot is extended or is projected in inboard the place ahead.The heel of this form is called thomas' heel, after the heel of first step lands in four walking steps, can make pin form the form of turn up (Supination).That is, sole forms extension 41 because of the inboard of thomas' heel extends to the place ahead than the outside when landing; So, when pin carries out second step after heel lands whole pin lands, in the middle foot 30; Pin tilts to the outside that does not have heel naturally, thereby has been formed naturally the state that turns up.

Also have, as shown in Figure 3 between the main body 90 of heel 70 and sole in the rear end of back foot part 40, be folded with the padded coaming 80 of chock shape.When the padded coaming of this form forms dorsiflex in the first step of four steps of walking heel lands, play the effect that relaxes the impact that puts on pin.Just, padded coaming be not arranged on heel 70 all on, and only be formed on rear end (suppose from the calcaneum that is projected into pin inboard part or anklebone rear 1cm later) to end.This padded coaming 80 that is formed on the whole heel 70, the step that lands improved pin about mobile, played preventing stability reduce the pin that causes toward the side askew accident.

When dress had the footwear walking of the as above sole of Fig. 2 and Fig. 3 institute structure, it acted on as follows.

At first, find out from the natural walking pattern that the light pin carries out, when the light step is capable, pin from outside toward the mode activity of interior swing and walking, thereby therefore the energy consumption when having reduced walking, can do long walking.In the walking of swing mode, the outer side edges of pin lands earlier, and then sole all lands, the heel built on stilts, and body weight is applied to toe portion, toe portion pushing ground.Promptly; Pin after heel touches ground, before pin all lands, carry out from turn up (inboard of sole lift and be turned back to health outside the) state in turn over the motion of (the health inboard is lifted and is turned back in the outside of sole) state; After sole touches ground; Toe portion returns then till pushing ground, carries out the motion of turning over state to the state of turning up from interior.

But; The bottom surface of general sole in the past is equivalent to horizontal plane, when pin forwards sole to and lands after heel lands, scarcely passes through outer side edges; And whole sole lands; So the outer side edges that can't successfully carry out pin is than the inboard motion etc. of turning up that lands earlier, it is capable to be different from original light step, therefore increases the tired of pin easily and reduces walking efficient.

And when utilizing the sole of present embodiment, in the first walking step, heel lands forming under the dorsiflexion of foot state.Back foot part 40 rear ends of corresponding heel portions are provided with padded coaming 80 with the chock state, therefore can relax the impact in the step that lands.

Then, in the second walking step, pin becomes the sole of the foot from dorsiflexion of foot stretching, extension ankle bends, and whole pin touches ground.At this moment, sole is not simple flat form, but is provided with heel 70 in the back foot part 40, and particularly heel 70 is a thomas' heel, and 1cm to 1.5cm is forwards extended in its inboard.So, touching transitional period on ground at whole pin, inboard sole is thick because of thomas' heel has formed at middle foot, the state that outside sole is thin.So, the pin biased outward, outside of foot lands, and has formed (the health outside is lifted and be turned back in the inboard of the sole) state that turns up.

But health is not to turn round outward, for measured step is capable forward, so do not advocate the excessive state that turns up.The excessive state that turns up brings burden might for the undue sole muscle that reduces of the height that suppresses the inboard arch of foot of pin (arch) when in being transformed into, turning over state.So, in the present embodiment, foot 30 front ends or during during the pin that lands behind the state that turns up arrives to the metatarsal portion 20 of front foot portion; The rear portion of the additional heelpiece 50 of cause is thick; And the outside of additional heelpiece 50 is after sole more leans on, so at the third step initial stage, heel is according to the effect of additional heelpiece 50 outsides at the bottom of because of the extra depth shoe of rearward end 51; And be tilted the thin inboard of sole, thereby, the state of turning up turns over state in being transformed into naturally.

As shown in Figure 4, in the 3rd walking step, when heel lifted, weight was concentrated the metatarsal portion, particularly metatarsal portion part of sole, and the angle that the proximal phalanx of the toe that metatarsal head is connected with it forms increases.At this moment; Be arranged in the common solid and unbending sole of phalanx portion, be removed a part of thickness and be in thin state, and have the groove 53 of flexible additional heelpiece; Therefore, lift heel increase in the resistance ratios of footwear during angle between foot and proximal phalanx reduced in the past.

Especially, remove under the state of a part of sole in the metatarsal portion part, be provided with the soft resilient material 60 that is used to disperse and relax the pressure that is applied to metatarsal portion towards the top (upside) of sole.This elastomeric material more moves down metatarsal head in lifting calcaneal step, therefore increase the angle of proximal phalanx and metatarsal, and the intensification of bending for the sole of the foot that carries out next step also becomes easily, is of value to and improves walking efficient.

The 4th step in walking is forward foot in a step pushing, and the toe of toe section forms little bow, and angled metatarsal of curved and proximal phalanx stretching, extension each other in third step; Toe is toward pusher ground; Then prepare to carry out again the first walking step, and form dorsiflexion of foot, pin leaves from ground.

Bend the state of deepening because of being in the sole of the foot, utilize the elastic force of putting aside pin muscle, more effectively push ground with the forward foot in a step.In addition; Under the effect of the screen resilience of the elastic energy that compressed elastomer is put aside; The metatarsal of pin is upwards pushed away, therefore push away the step on ground, consider lever principle at toe; The form of the pin that the forward foot in a step is had help pushing, and be convenient to pin and form dorsiflexion of foot in next step the first walking step.

At this moment, because of third step turns over state in being in, therefore in the 4th step, mainly by pin inboard (pin thumb one side) pushing ground, and according to this effect, pin is changed to the form of turning up from interior upset.

See that from the gait processes of four steps similar with the natural walking of light pin in the present embodiment, the process that pushes ground from landing to appears turns in being transformed into from turning up, and changes to the form of turning up from interior upset again.And, in the present embodiment, from interior translate into the conversion of turning up and from outside the conversion of turning in translating into mainly be that structure according to sole carries out; Therefore compare with pin oneself conversion, reduced burden, particularly; Concerning the user of pin muscle deterioration, the burden of the pin when having reduced walking.

Sole upward view and the front elevation of having represented another embodiment of the present invention among Fig. 5 and Fig. 6.

Though diagram not among this embodiment, supposes such as women's high-heeled shoes etc. left and right sides narrow width and highly high heel to be bonded in the situation of back foot part.The left and right sides width of heel is assumed to be below the 3cm, highly is assumed to be 5cm when above, the distinct effect of thomas' heel shown in the embodiment of performance and Fig. 2 in walking.At this moment, with turn up in the walking with in turn over compared, the safety that should pay the utmost attention to pin lands.Heel is not only thin but also high, ankle then can't about stable, so the problem that takes place frequently and sprain one's ankle.Also have, even without spraining one's ankle, the user is for the balance about keeping, and walking is very inconvenient.

Under this situation,, the additional heelpiece 250 of present embodiment is set in the metatarsal portion 20 of the sole that connects heel 290.Additional heelpiece 250 backward; Promptly extend to middle foot; Left and right sides in this extension be provided with towards the outstanding protuberance that faces down (stability column: 255,257), this outstanding position lands earlier than metatarsal portion 20; Play the effect that sole is landed in advance, and play the effect of the adjusting left and right sides balance identical with thomas' heel.

Thus, present embodiment plays the effect of the balance on the left and right sides width of when the women lands with leather shoes, keeping pin, and prevents the tired and accident that twists leg of pin.

Fig. 7 representes the front elevation of another embodiment of the present invention.

Similar at present embodiment with Fig. 3, constitute by the main body 390 that is divided into 2 layers along thickness direction.Be provided with padded coaming or elastomeric material 360 near the metatarsal head of the metatarsal portion on upper strata substantially, in the whole length of lower floor, metatarsal portion is formed extremely thin, and this thin part is provided with additional heelpiece 350.It is the mounting groove 358 of length direction that the rear part upper surface of additional heelpiece 350 is provided with the left and right sides width of pin, and is inserted with the big or small corresponding metatarsal horizontal stripe 359 with mounting groove.Through this metatarsal horizontal stripe, the rear portion of additional heelpiece is formed thicker than the embodiment of Fig. 3, and this part plays when walking from the latter half of effect of pushing sole and massaging of metatarsal.Because the reason of metatarsal horizontal stripe obtains the effect that Calf muscle relaxes and stretches, the metatarsal horizontal stripe can be induced correct walking posture and stance.In the present embodiment, the metatarsal horizontal stripe that will have this effect is set directly in the sole, thereby has saved the trouble of the parts that footwear such as shoe-pad need be set in addition.

Fig. 8 has represented the sole front elevation of the metatarsal horizontal stripe of setting and Fig. 7 different shape.

In the embodiment of Fig. 8, identical with the embodiment of Fig. 7, be provided with additional heelpiece 450 1 layer sole main body 490, on additional heelpiece, embed in the mounting groove 458 of formation be provided with darker than the mounting groove degree of depth, the metatarsal horizontal stripe 459 that top is outstanding.Sole presents the form that is run through in the position that is provided with the metatarsal horizontal stripe; With compare above the peripheral sole that has the sole main body to constitute; The top of metatarsal horizontal stripe more projects upwards; So, from the metatarsal bottom of sole directly outstanding part push foot arch part anxiety muscle and played the effect of relaxed muscle.

Fig. 9 is the footwear that expression will be suitable for sole as shown in Figure 8, the general profile chart when blocking by length direction.

Be provided with cushion (insole) 500 above the sole of Fig. 8, be formed with upper of a shoe 300 parts above it.The periphery of upper of a shoe 300 presss from both sides substantially and is set between sole 490 and the cushion 500.For the sole that makes the part of giving prominence to sole through the metatarsal horizontal stripe 459 of sole touch the user effectively works; In the cushion above being arranged at sole (insole), also be formed with the corresponding to outstanding position 310 of crest curve that constitutes with the metatarsal horizontal stripe.This part adopts other part identical materials with cushion, and just its shape projects upwards, thus change its thickness or material appends or weighted shoes at the bottom of the effect of metatarsal horizontal stripe, or form the formation portion identical at cushion independently like the metatarsal horizontal stripe with sole.

The above has specified the concrete example that the present invention puts down in writing, and those skilled in the art can carry out various distortion or correction in technical scope of the present invention, and its distortion or correction all belong within the accompanying patent claim.
