Description

Footwear with moisture discharge device

The present invention relates to a kind of footwear with moisture discharge device, especially sport footwear, for example running shoes.

The ventilating problem and the exhausting problem of footwear inside all exist for a long time, but never thoroughly solve satisfactorily.

For this reason, the climbing boot of a kind of commodity by name " CLIMA-COMPREX " has non-leakage outer group, and interior footwear core then has some cannelures on its outer wall, these grooves with cross described footwear core, communicate in order to the hole of discharging the air of being with moisture.

The problem of this footwear is that its deflation rate is too limited, so the deficiency in draught of footwear is to eliminate moisture.In addition, because pin can cause condensation problem away from the outer wall of footwear core, to be exposed to low temperature environment problem of following time just more serious when outer upper of a shoe.

Also utilize so-called " saturating vapour is waterproof " material to attempt multiple different structure.Described vapour impermeable material just is meant that this material can see through steam, but water porous not.Described structure has good external sealing really, but exist hypopnea in other words moisture discharge inadequate shortcoming.

In fact, the respiration capability that so-called vapour impermeable material or film provide is still very little, in fact can only satisfy pin the humidity discharging needs 10%.

Recently, as depicted in figs. 1 and 2, Boreal company a kind of mountaineering boots of having finalized the design, this footwear have the outer upper of a shoe 1 of a skin and the lining 2 of a sandal-style, and lining is used for humidity discharging, is made of a bottom 21 and a top 22, described bottom surrounds the foot of narrow sense, and described top then surrounds ankle.

Shown in Figure 1A was detailed, the bottom 21 of described lining was a multilayer material, and it from inside to outside comprises:

-one deck three dimensional fabric 25,

The film of-one deck " saturating vapour is waterproof ", the commodity of this film are called " Sympatex ", are bonded on one deck protection tissue layer 26 (wear-resistant),

-one deck constitutes the leather of outer upper of a shoe 1.

The top 22 of described lining is made of one deck leather 27 and foam 28.

Described two parts 21-22 couples together by enclosing suture 23 on one, and is same, encloses 24 bottoms 21 with lining of suture under one to be connected on the sole.

The use of described three dimensional fabric 25 is can laterally and on vertical discharge for steam.

In practice since on the existence of enclosing suture 23 and enclosing suture 24 down, just stoped the discharging of described steam on vertical.

Therefore, sweat vapour just can only in lining bottom 21 transversely pass the skin outer wall discharging of the film 26 and the described outer upper of a shoe 1 of described " saturating vapour is waterproof ".

Yet as previously mentioned, described " saturating vapour is waterproof " material can not guarantee the abundant discharging of moisture, so effect is so not desirable.

Therefore, the objective of the invention is to remedy above-mentioned defective, a kind of improved footwear structure is provided, make and to discharge the moisture that produces because perspire better.

Of the present invention by one outside in the footwear of the style that constitutes of upper of a shoe and an inside liner, described purpose reaches like this: described inside liner is made of one deck compound fabric, this compound fabric comprises two-layer parallel fabric, knitting line by one deck therebetween couples together, knit line and be substantially perpendicular to the face that two-layer fabrics forms, this compound fabric just forms a compressible space between two-layer fabrics like this; Lining is the upper end of upper of a shoe outside the bottom extends to always, and only by enclosing suture on one itself and outer upper of a shoe is coupled together.

Described compound fabric is commonly referred to three dimensional fabric, forms the air layer around foot on the whole surface of lining, and extend to the top of upper of a shoe always, thereby make from the top of foot, realized the exchange face of a maximum, thereby realize optimum discharge moisture up to footwear.

Such structure has solved the too limited problem of exchange surface, for example existing problem under the situation of the structure of foregoing use " saturating vapour waterproof " layer or groove-transverse holes system.

In addition, lining has only guaranteed that by enclosing the connection that suture forms on one moisture can discharge on the upper of a shoe outside on vertical basically direction, that is to say from sole upwards discharging always.

According to a kind of favourable embodiment, inside liner forms a footwear core, and himself is sewed up to suture by a single central longitudinal.This structure has guaranteed the good circulation of moisture equally, because moisture can be discharged from the edge of sole to the footwear core by central suture.

By reading the explanation of doing with reference to accompanying drawing, the present invention may be better understood.

Fig. 3 C is the detail drawing that is similar to Fig. 3 B of another kind of embodiment.

Fig. 4 is the view that footwear core of the present invention is similar to Fig. 2.

As shown in Figure 3 and Figure 4, footwear 100 of the present invention are made of the inside liner 120 of an outer upper of a shoe 100, sole 101 and a slippers shape.

Different with footwear core of the prior art 2, the footwear core 120 among the present invention is a kind of continuous structures that begin from the bottom, that is to say that all be continuous from sole 121 up to its upper end 122.

As shown in Figure 3A, footwear core 120 is made of three-dimensional composite material, be such material: be respectively the two-layer fabrics face of internal layer 124 and outer 126 or knit layer, these two tissue layer 124 and 126 are knitted line layer 125 by one and are coupled together, wherein knit the face that line is substantially perpendicular to two tissue layer places, but and between two tissue layer 124 and 126, form the air layer of an elastic compression.Such three dimensional fabric is made in a manufacturing step usually.It also can constitute like this: independent respectively two tissue layer that realize couple together with an air layer on its thickness direction again.Two tissue layer 124,126 preferably are made of the flat knit layer, also can be made of braiding or non-woven line layer.

Under any circumstance, constitute all preferably hydrophobic synthetic material of material of three dimensional fabric.

The internal layer 124 of close user's pin preferably is made of large-mesh flat knit layer, so that the sweat of pin has best discharging on radially (just being approximately perpendicular to the direction on internal layer 124 surfaces).

Although not necessarily, outer 126 preferably combine with an extra play 127, and " saturating vapour is waterproof " film (referring to Fig. 3 C), for example " Gore Tex ", " Sympatex " or products such as " Clima Dry " arranged on the extra play.

In the case, extra play 127 preferably is made of close meshi fabric, with effective tread support membrane and protect it not frayed.

As shown in Figure 4, footwear core 120 is made of two compound fabrics that cutting forms, and is sewed up by a single vertical suture 123, and this suture is roughly on vertical midplane of footwear core 120.

Therefore, pin sweat can be from the bottom 121 of lining from the both sides free flow of vertical suture 123, and, shown in arrow V, rise to the upper end 122 of lining always, and can not be subjected to the obstruction of horizontal suture (suture 23 of footwear core for example shown in Figure 2) along the vertical wall of lining.

Therefore, the whole surface of lining 120 all can be used for discharging the moisture that produces because of perspiration from bottom to top by ringing, and the moisture of heat passes the air layer that is limited by layer 125 and circulates on vertical.

Because the discharging of moisture realizes basically in the vertical, that is to say on the face of the material that constitutes lining or thickness and realize, rather than the radial discharge by passing material walls (as under the situation of the known technology of footwear illustrated in figures 1 and 2) realizes, apposition layer 127 does not hinder the discharging of moisture on " saturating vapour is waterproof " thin layer, the sealing that but can realize ideal in addition is to realize real " sealing is breathed " structure.

As shown in Figure 3A, lining 120 in the top 122 by a periphery suture 123 with outer upper of a shoe 110 edge-to-edges sew up, turnover is returned then.Therefore this suture 123 does not hinder the circulation of moisture to lining upper end 122.

" laterally " suture 130 can also be provided between lining 120 and upper of a shoe 110, form a comfortable ring pad with rear portion at footwear.As long as this suture 130 is only on the part periphery of lining upper end 122, with regard to the discharging that can too not hinder sweat vapour to make progress.

Upper of a shoe 110 preferably is made of ventilative material, for example leather 111, and combines with conformable material, for example foam 112.Certainly, the material of any kind comprises encapsulant, can be used as all or local of upper of a shoe.

Can notice that the three-dimensional structure of lining can also limit the consumption and the thickness of the comfortable foam that is used for upper of a shoe, because itself just played certain comfortable effect by the formed air layer of three-dimensional structure.

The swabbing action that distortion produced (contraction of material and expansion) of footwear realizes when advancing specifically in the circulation of air of foregoing V direction.

Owing to following reason, in foregoing lining structure, the discharging of moisture and circulation effect are very noticeable:

-because very near awfully hot pin itself, in lining, moisture keeps gaseous state, and can not resemble condensation footwear core end provides in the structure of footwear of ventilation slot,

-three dimensional fabric attracts moisture by itself and user's socks or the capillarity of the contacted inner surface of pin, makes the moisture that keeps in touch with pin almost not have.

In addition, described structure also has other advantage:

-as previously mentioned, three dimensional fabric has also played comfortable effect by its flexible internal layer, but elastic inner layer elasticity when pressurized is out of shape immediately.In addition, this elastic layer always returns to original state, can not subside the conventional foam and can not resemble,

The air layer of-storage in three dimensional fabric strengthened the insulation effect of footwear, thereby the thickness of the foam that provides for this purpose can be provided.Under the identical situation of hot comfort, footwear just can contain less foam, and foam can be built up moisture, gain in weight,

-to compare with traditional lining, the lining drying of three dimensional fabric is got up faster, and this is to be made of hydrophobic material because of it, and exchange area is big.

Certainly, the invention is not restricted to above-mentioned non-limiting embodiment of giving an example, and comprise its any similar or embodiment of being equal to.

Especially, the present invention is not limited to the sandal-style lining, and the lining part at extend upper end from the end to the upper of a shoe also can have goodish effect.
