Abstract

The invention relates to a self-ventilated, ergonomic footwear item and an elastomeric sole. According to the invention, both sides of the sole comprise a plurality of longitudinal grooves, in the area corresponding to the sole of the foot, which are essentially parallel to the edge of the sole closest thereto and which have a depth equal to half of the height of the sole. Moreover, the grooves are disposed in an alternating manner in relation to one another on either side of the sole in the form of a bellows-type structure. The upper comprises a perforated elastic laminar body which is disposed beneath the insole in the area corresponding to the sole of the foot and which, together with the sole, forms a chamber having a volume that varies upon walking. In addition, three thick bands are solidly connected to the body and the upper in order to stiffen said elastic laminar body, namely: one longitudinal band and two transverse end bands. In this way, the footwear item and the sole adapt perfectly to the anatomy of the foot, enabling same to be automatically ventilated upon walking.

Description

From ventilative, bionic footwear and sole

Goal of the invention

The present invention relates to the sole that footwear and described footwear comprise, but this sole is applicable to the footwear of other type.On the one hand, since usually by injection molding form flexible sole or analog, subsequently cover go up shoe-pad and and corresponding upper of a shoe combine to finish this footwear, from the biotechnology angle, these footwear can provide best performance, footwear self ideally adapt with user's pin, and and the length of described pin and wide between various different relations irrelevant, on the other hand, automatically generating internal is ventilative in the time of can making on foot, and the comfortableness of having promoted this respect.

Thereby, the objective of the invention is to obtain to be fit to and the angle of the gas permeability of footwear provides the footwear of bigger comfort level for the user from pin comfortable, and at the upper of a shoe that has the transverse height strain corresponding to the sole zone of pin, comfort level with the footwear of promoting the user, footwear self are adapted with pin anatomically, and have nothing to do than big or width smaller with it.

Background technology

In the scope of footwear, more specifically in the scope of the sole of same footwear, a normally used scheme is, by obtaining sole with the elastomeric material injection molding.

The hierarchical table long according to pin made outer bottom according to predetermined size, and like this, anyone can find the footwear that are fit to the long size of its pin on market.

Because for the footwear of particular type or design, transverse width is fixing usually, so be not that anyone can find the suitable wide footwear of its pin on market, as known to, this is for very serious problem of the people Lai Shuoshi with " wide pin ", these people have to stand the discomfort of the footwear of pinch, perhaps, because the size of footwear increases, its width is just along with increase, so they have to use than growing the big size of employed size according to pin.

This way to solve the problem is to use the last of different in width, and this particularly from the angle of production and apportioning cost, obviously has very negative effect from the viewpoint of economy.

A kind of upper of a shoe that hinders less solution to be to use soft material, this method has partly solved problem, especially wide when a lot of unlike normal pin when user's pin, but it can cause the footwear distortion, and footwear can lose its original outward appearance fully in use for some time.

On the other hand, these elastic sole can not be breathed freely in fact because its distinctive character, so they perspire user's health, thereby wish that footwear is ventilative in having, so that sweat just evaporation when producing.

The footwear of gas permeable devices in existence has on the market, but currently used solution complex structure, and invalid on the function, thereby its actual use propagandas of depending on advertisement, rather than the actual effect of this respect more.

Summary of the invention

Footwear that the present invention proposes and sole have solved described two aspects in a kind of mode that is entirely satisfactory the problem that preamble was proposed, the optimum performance on the biotechnology viewpoint is provided, the anatomy that also adapts to user's pin well makes to produce described breathing freely automatically when walking.

Be this purpose, and more specifically, footwear of the present invention are on the basis of using the elastic sole that for example obtains by injection molding, with the characteristic feature of described sole with influence the further feature that its complementary upper of a shoe also can have the effect of wanting and combine.

Particularly, sole has a plurality of longitudinal flutings in the zone corresponding to the sole of pin, they are in the extension between the place that begins of toe and arch of the foot, it is functionally not only disposed thereon or inboard but also be arranged on it down or on the outside, groove is about half of this zone sole thickness, described a plurality of longitudinal fluting, be preferably curved path, this path is parallel to the lateral edge at the sole of its band of position, characteristic is that the groove of the groove of its upside and downside is staggered, like this, this zone of sole is set up and is the bellows pattern, make sole in the described zone of sole because pin can the transverse elasticity distortion according to the width applied pressure of pin, this point in the place with problem that " wide pin " caused clearly.

Correspondingly, to have a normal pin wide as the user, original size corresponding to the width of the sole in sole zone remains unchanged, but demand for pin with broad, the sole in sole zone can be easy to take place horizontal expansion, promptly widen, make it to adapt to the needs of pin, make footwear that the comfort level of height be arranged.

This comfort level preferably can extend to the user of any kind, because identical elastic deformability taking place under normal condition, thereby makes footwear because it has a softer end thereby more comfortable under the situation that does not change material.

Replenish ground, usually the upper of a shoe by the shoe-pad sealing comprises elastomer in the sole zone in the bottom, this elastomer is because himself character helps in the sole zone that this is mentioned repeatedly along the distortion in a lateral direction of footwear, and it also has the opening that makes the air turnover of suitable distribution.Thereby, form a chamber between elastomer and sole, one when walking, owing to constitute the expansion and the contraction of its element, the volume in chamber changes, this volume-variation causes " breathing " effect, and like this, air passes in and out described chamber, make the interior pin in zone of footwear breathe freely, because the heel area inlet by pin usually is ventilative, so this zone is the most problematic zone of this respect, i.e. the closed area of sole.

Description of drawings

Be supplementary notes, and understand the feature of the present invention according to an one preferred embodiment better, provide one group of accompanying drawing, as the part of an integral body of described specification, it is exemplary and non-limiting, as follows:

Fig. 1 shows the perspective schematic view of the sole of the footwear of implementing according to purpose of the present invention, shows its upside.

Fig. 2 shows and the similar schematic diagram of earlier drawings, but shows the downside of sole.

Fig. 3 shows the parts decomposition view of ventilative certainly, the bionic footwear of implementing according to purpose of the present invention, and wherein, upper of a shoe and sole show must be adjusted and a fixing side.

Fig. 4 shows the sectional detail drawing of the assembly of the suitable assembling shown in the earlier drawings,

The specific embodiment

Referring to Fig. 1 and 2, can see the sole (1) that the present invention proposes, as arbitrary traditional sole, form by the standard single piece body partly that has corresponding to sole, arch of the foot and heel, particularly about the outside shown in Figure 2, any finishing or configuration according to the design that provides for sole can be provided these parts.

The present invention concentrates on following this fact, sole (1) side within it comprises the longitudinal fluting (5) that a plurality of homogeneous distribute in the zone corresponding to sole, the practical embodiments further groove number that provides in the drawings is five, but this number can change under the situation that does not influence essence of the present invention, groove is preferably shaped form, and is parallel to side and is right after the main body of sole.

The described groove (5) of sole upside is supplemented with other lower recess (5 '), see as knowing among Fig. 4, its must with and the mode that replaces of upper grooves (5) be provided with, for this reason, the number of lower recess must be greater or less than upper grooves (5), the groove number is more in selected embodiment middle and lower part, is six specifically.

The degree of depth of groove (5) and (5 ') is compared with the thickness of the sole in sole zone, it must be about described thickness half, to obtain the bellows type structure shown in Fig. 4, this structure makes sole have suitable structural stability, yet the user in particular cases at " wide pin ", still make that sole can be along transverse width direction strain, so that himself adapt to the size needs of aforementioned pin well.

Apparently, the standard shoe-pad and the upper of a shoe that cover owing to inside are easy to distortion, so sole (1) can not be subjected to their obstruction corresponding to this strain in the zone of sole.

Obviously, any problem can not occur owing to have the crowd of " wide pin " usually in the arch of the foot or the heel area of footwear, the excessive width of pin appears at the zone corresponding to sole, so described groove (5) and (5 ') neither can influence arch of the foot, also can not influence heel.

Referring to Fig. 3 and 4, can see that how footwear proposed by the invention form by sole (1) and upper of a shoe (2) are combined as arbitrary traditional footwear, the latter has lower inner periphery edge (3) to cooperate by means suitably and to be fixed to sole (1), standard shoe-pad (4) is with user's pin and suitable the keeping apart of sole (1), and be decorative purpose, this shoe-pad (4) can randomly be set at other inboard shoe-pad of upper of a shoe (2) and cover.

Complementally, in upper of a shoe (2) and sole zone corresponding to footwear, particularly below shoe-pad (4), a sheet elastomer (6) is set, it suitably is fixed on the upper of a shoe (2) at its profile place, for example be fixed on the aforementioned circumferential edges (3), elastomer (6) is allowed and is helped footwear and is out of shape along horizontal direction, according to a preferred embodiment, it vertically is with (7) and a pair of transverse end band (8 by one, 8 ') strengthen, can know in Fig. 1 and find out that they all are fixed on the sheet elastomer (6), suitable words, be fixed on the edge (3) of upper of a shoe, these bands (7-8) are used for suitably making elastomer (6) stable, limit two independently side deformed regions within it.

On the other hand, the thickness of these bands (7-8) helps between elastomer (6) and sole (1) variable volume chamber (9) being set, when feet on the ground, the volume in chamber can reduce, and air flows out from described chamber by a plurality of openings (10) that are arranged on band (7) and (8), and gas enters the useful inside of footwear, and when when pin is lifted on ground, because the elastic recovery of main body (6), the volume of chamber (9) increases, and gettering effect occurs.

Therefore, according to described structure, as described, the groove of sole (1) (5-5 ') with and elastic property make the sole horizontal direction can strain, like this, footwear cosily adapt to user's pin, and how do not consider its width, simultaneously, chamber that produces between elastomer (6) and the sole itself and the opening (10) that is connected with footwear inside, make footwear inner ventilative, utilize the motion of " breathing " type of air, the global comfort of having promoted footwear the biglyyest.
