Abstract
A shoe having a synthetic resin upper, which can be easily and inexpensively mass-produced and has both waterproof and air-permeable properties. The size of the air holes on the vamp is designed to ensure that the surface tension can prevent water from entering the shoe through the air holes.
Description
The present invention relates to be easy to make, can cheapness carry out large-scale production, is the footwear of vamp with synthetic resin.More particularly, this kind vamp has gas permeability, can suppress humidity and be heated, and the anti-water of energy is to stop in the water intrusion footwear.
Natural leather is because of its attractive in appearance and ventilative vamp that is commonly used for the high-quality footwear.But natural leather is except that ventilative, because capillary attraction can also be permeable.So natural leather has the shortcoming that makes footwear become tide in the rainy day.In addition, because leather originally was in the plain film form, its that must form time can be attached intermediary's sole of footwear and the 3 D surface shape with suitable pin shape, and then has and will consume a large amount of labours in the mill, take shortcomings such as advanced technology and expensive production process.It also has owing to the distortion shortcoming that becomes 3D shape to produce from intrinsic two-dimensional sheet materials processing, and is difficult to produce and is similar to the sort of footwear comfortable and easy to wear of sport footwear, and this is can not fully stretch because of leather itself.
The inventor manufactured experimently out the footwear that a kind of upper portion ground was made by synthetic resin already, to solve the aforementioned variety of problems relevant with natural leather (day disclosure specially permit number 38241/1982).
Footwear of the present invention has following characteristics.Be pressed into three-dimensional surface spare because vamp is the profile die according to pin, compare with the natural leather vamp, it is large-scale production at an easy rate; Because the shape of vamp and instep coincide and can stretch, its regional area can not be in over-stressed state, and such footwear are convenient to cosily wear for a long time.In addition, because the 3D shape here is to use mould molding, such footwear its shape that can not relax.
Further, handle, then can on the surface of this synthetic resin vamp, print out and the similar three-D pattern of natural leather by the inner surface of shoe mould being done galvano-cautery.Like this, just can produce a kind of footwear that are difficult to the synthetic resin vamp of the beautiful pattern appearance of high-quality natural leather difference that have.
But main and only shortcoming of the footwear of synthetic resin vamp then is to lack ventilative such key factor.Therefore, if the vamp of the synthetic resin that possesses natural leather or fabric ventilation character can be arranged, just might produce a kind of highly desirable footwear.
On the synthetic resin vamp, form and penetrate the net-like pattern of vamp or big hole, just can solve ventilative problem.But, as above-mentioned leather shoemaking, have the vamp of such configuration, will when allowing air enter, also allow water enter, allow pin become wet shortcoming and just have when wearing this kind footwear in the rainy day.According to such mode, can not realize round-the-clock footwear.
Passed through for many years and utilized all experiments of new material properties, attempting and error, the inventor attempts to develop a kind of synthetic resin vamp ventilative and this obvious contradiction character of waterproof that has.A kind of vamp of synthetic resin when it has the structure extremely different with the dense set zoarium of the numerous fibers that constitute natural leather, can not absorb water because of capillarity in this synthetic resin vamp.Particularly this synthetic resin vamp is the in-mold molding that molten synthetic resin is injected into reservation shape, and the vamp that is formed by this technology simultaneously is by synthetic resin filling Cheng Erwu gap or hole basically.Known vamp with this spline structure is not allow water or air to pass through its, and it is adsorbed water not, has excellent hydrophobicity matter.
By effectively utilizing a kind of physical property of uniqueness, it is surface tension, this character also plays main effect to the capillarity that causes the natural leather suction, the inventor had successfully been developed a kind of synthetic resin vamp already, it can provide fully ventilative character, can stop water to enter in the footwear from air-vent effectively simultaneously.
Therefore main purpose of the present invention provides a kind of round-the-clock synthetic resin shoe with vamp of peculiar ventilative and water-resistance matter, and it can make dress happy and at the rainy day pin that can not wet.
Another free-revving engine of the present invention provides the synthetic resin shoe that there is air-vent in a kind of the place ahead at pin, and it can prevent moist effectively and be heated, and can be easily, large-scale production at an easy rate.
In footwear of the present invention, the major part that includes at the vamp 1 of pin the place ahead part is to be formed by synthetic resin.On the lower edge of pin the place ahead part, be provided with many air-vents 3 along vamp 1, and, the diameter D(mm of air-vent 3) satisfy following three conditions.
For have air-vent 3 and since then air-vent 3 to the height of welt 10 lowest parts be H(mm) the zone in thickness be W(mm) vamp 1, the diameter D(mm of air-vent 3) must satisfy:
（a）D＜30.2/H
（b）D≤W
（c）D≤1.5
In addition, in footwear of the present invention, be preferably in and insert a hydrophobic lining 6 on the inner surface of vamp 1, invade by air-vent 3 to prevent any water.
The synthetic resin vamp 1 that this footwear of the present invention has has effectively utilized hydrophobic and capillary elite clone character, and anti-sealing is invaded by air-vent 3.
In other words, as shown in Figure 1, this footwear are at the water surface during near the welt 10 of vamp 1, want anti-sealing and see through air-vent 3 and invade, as long as water does not flow to welt 10, just do not have water and flow into through air-vent 3.
In situation shown in Figure 1, water enters air-vent 3 under maximum pressure.The hydraulic pressure that is applied to air-vent 3 is directly proportional with the air-vent 3 underwater degree of depth.Therefore, be distributed in the top of vamp 1, just can reduce the depth of water and the pressure that affacts on the air-vent 3 by making air-vent 3.But owing to have the easiest heating in bottom of synthetic resin vamp 1 and make moist, air-vent 3 not being located on the bottom margin of vamp 1 is to make the good footwear of breathing freely.
Although be proportional to the hydraulic pressure of the depth of water is to act on air-vent 3 at vamp 1 bottom margin place, the water of under by air-vent 3 pressure reduction, invading by air-vent 3 in the surface tension of water stopped.
Referring to Fig. 2, the water that enters air-vent 3 is because the hydrophobic effect of synthetic resin and tool hemispherical, and surface tension T then acts on and stops water to enter direction in the footwear.Make a concerted effort F when entering the pressure f of the water in the air-vent 3 when what formed by each surface tension T, and water promptly is prevented from entering in the footwear.
When water is T(dyne/cm for the surface tension of air) and the radius of air-vent 3 is r(cm) time, the F that makes a concerted effort that forms by the surface tension that stops in the water intrusion footwear then, promptly can be the air-vent girth (2 π r, cm) and the two long-pending given of surface tension:
F＝T×2πr（dyne）
In addition when depth of water differential pressure be h(cm) time, trend towards flowing into the pressure f (dyne) of the water of air-vent 3, be air-vent 3 area of sections (π r
2, cm
2) multiply by hydraulic pressure (dyne/cm
2):
f＝πr
2×h×g×ρ（dyne）
Wherein g is acceleration of gravity (980cm/sec
2), and ρ is the density (1g/cm of water
3).
When condition F＞f satisfies, can stop water to be invaded through air-vent 3.The surface tension T of water slightly changes with temperature, is about 73.48dyne/cm in the time of 15 ℃.Get surface tension T now and be 74dyne/cm and quote equation (1) and (2), trend towards flowing into the pressure of air-vent 3, when satisfying with lower inequality
r＜0.15l/h
The time, just be lower than the opposite force that constitutes by surface tension T.
When cm is scaled mm, when the diameter of air-vent 3 is D(mm), and water height in the zone on air-vent 3 is H(mm) time, D=2 * r * 10 are then arranged,
H=10 * h and
D＜30.2/H
What Fig. 3 provided is the curve map of the relation of the depth of water and air-vent 3 diameters, trends towards flowing into the pressure f and the capillary F balance of making a concerted effort that stops water to enter of the water of air-vent 3 this moment.
From then on curve map for the air-vent 3 of 1mm diameter, can stop the water that is up to the 30mm degree of depth to enter in the footwear through air-vent 3 obviously as can be seen.
As mentioned above, for situation shown in Figure 1,, there is maximum pressure to act on them when air-vent 3 is when being distributed in the bottom margin place of vamp 1.In other words,, perhaps for example be that when the footwear of dress were in the deep water hole that water can not flow into vamps 1 by welt 10, the pressure that acts on air-vent 3 was for maximum when horizontal plane is positioned at welt 10 places.This depth of water is equivalent to the height H of 1 upper shed 10 from air-vent 3 to vamp.Therefore, be the footwear of 30mm for the height of 1 upper shed 10 from air-vent 3 to vamp, as long as make the diameter of air-vent 3 be not more than 1mm, just can utilize surface tension to stop water to enter in the footwear.
If as shown in Figure 2, the hemisphere face forward position of the water in air-vent 3 is projected into outside the inner surface of vamp 1, and it just will touch vamp lining 6 or sheath, and can not stop the intrusion of water.Because the diameter D of footwear of the present invention institute tool air-vent is less than the thickness W of vamp 1, the hemispherical forward position of water just can not be projected into outside the inner surface of vamp 1 in the air-vent 3, thereby just can stop water intrusion in vamp 1.
The internal diameter of the air-vent 3 here further is restricted to and is no more than 1.5mm.Diameter is the water intrusion that the air-vent 3 of 1.5mm can prevent to reach deeply 20mm.Although air-vent 3 is opened on the bottom margin of vamp 1, usually still on about 10mm on the footwear root bottom part.
Like this, have the footwear of the air-vent of the 1.5mm diameter that is positioned at 1cm place, sole top,, just can prevent the intrusion of sealing when wearing it when walking in the dark puddle of 30mm.
The puddle that is no more than the 30mm degree of depth has following feature: even when wearing that this footwear are entered in this puddle suddenly and air-vent 3 when being subjected to the impact of water also can stop the intrusion of water.
Because footwear of the present invention have many air-vents at the vamp bottom margin, thereby it has following characteristics: it has the vamp of the synthetic resin that can provide ventilative; By the quantity and the size of freely regulating air-vent, the part that makes air lead to the heating of vamp most probable and make moist, making has best comfort when wearing; In addition, even sufficient gas permeability is provided, owing to can prevent that sealing enters in the footwear, or even in the rainy day, also can cosily wear, thereby this footwear are a kind of round-the-clock footwear.
Say more specifically, surface tension plays main effect for making water saturates cross the interfibrous space of natural leather vamp, here used its this advantage, add the hydrophobic property of synthetic resin vamp, just realized that this kind of the present invention has the footwear of the synthetic resin vamp that can stop this characteristic of the utmost importance of water intrusion.
Also have,,, thereby have the advantages that to carry out large-scale production simply, easily and at an easy rate because vamp is by molding synthetic resin though footwear of the present invention are the air-vent that is provided with comfortable and easy to wear.Accompanying drawing of the present invention is as follows:

Fig. 8 shows the schematic cross section of amplifying by lining provided on the vamp inside surface elastic deformability and ventilating performance.
The implementation procedure of the present invention's one most preferred embodiment is described referring to accompanying drawing below.But this embodiment is used as an object lesson of illustrating the technology that the footwear that make the present invention specialize, and footwear of the present invention never are limited to following embodiment.In the scope of appended claim book regulation, can make various other changes to footwear of the present invention.
In addition, should be readily appreciated that for making claims, in the specification used unit number be with appended claims of the present invention in unit number corresponding to.But the parts of pointing out in the appended claims never are limited in the specification the described parts of embodiment.
Footwear shown in Figure 1 are formed as a single-piece by synthetic resin, and it has an intermediary's sole 9 and a 1B of vamp basic unit, and the latter has constituted the part of vamp 1.Bottom margin along vamp basic unit 1B front portion is provided with a collection of air-vent 3.
The 1B of vamp basic unit and intermediary's sole 9 are got the three-dimension curved surface configuration with the instep profile, are by a kind of pliable and tough synthetic resin, for example are to be formed by polyvinyl chloride, polyurethane or this resinoid mixture.
The 1B of vamp basic unit is formed by synthetic resin, and vamp lid 1A then is sewn on the 1B of vamp basic unit, and attachment goes up sole 2 then.Not so, also can after forming, vamp 1 and intermediary's sole 9 again sole 2 be connected.
Diameter D(mm by air-vent in the restriction vamp 1) satisfies following three conditions, just can utilize surface tension to make footwear energy waterproof.
In other words, when the vamp 1 that is provided with ventilative porose area has thickness W(mm), and the height of the lowermost portion of welt 10 above air-vent 3 is H(mm) time, such footwear must satisfy following each condition: the diameter D(mm of air-vent) must not surpass the thickness of vamp 1 at ventilating area, or be D≤W, that is D≤1.5; In addition, this diameter D(mm) must less than, divided by the height H (mm) of welt 10 lowermost portion above air-vent 3, or be D＜30.2/H by the surface tension of water and the determined constant of density.
For ease of explanation, the welt of the vamp 1 here is meant to be opened to is enough to allow water flow into the interior zone of footwear.For whole vamp 1 is from the situation of synthetic resin by single formation, and this welt is the mouth that allows pin insert.But in footwear shown in Figure 4, the vamp lid 1A here is sewn on the vamp base 1B, and this welt has comprised the zone that vamp lid 1A and sewing holes are formed.In addition, the height H between air-vent 3 and the welt 10 is meant that when the footwear horizontal positioned, ventilation mouth 3 is the height between the welt lowermost portion therewith.
In rest configuration, by diameter D(mm with air-vent) be restricted to D＜30.2H, just can stop the intrusion of water.But when in actual use, this footwear can be put on for the someone energetically stage go in the puddle.So,, air-vent should be designed to less than value given above for waterproof effectively.
For example, when the height of welt 10 in the vamp 1 on ventilative empty 3 was 30mm, the diameter of the air-vent of determining by curve among Fig. 33 was 1mm.But preferably the diameter with this kind air-vent is designed to 0.6mm or littler, invades under the difference in height of 50mm to stop water.
In other words, for waterproof more effectively, the diameter of air-vent 3 is no more than (30.2/H) * 0.6.
Shown in the enlarged drawing in Fig. 5 and Fig. 6 and 7, be used for moulding and have the mould of the 1B of vamp basic unit of air-vent 3, utilized the former shell 5 that is provided with the nadel part that can charge into vamp mould 8, in vamp 1, to form air-vent 3.Remove this, before the mould closure, the protective lining 6 that will be used for vamp 1 is attached to the central part 7 of mould, and as Fig. 6 and shown in Figure 7, the taper of the nadel portion 4 that this cushions 6 is pressurizeed promptly for this reason lining 6 support.Under this kind state, the molten synthetic resin of pressurization just is injected in the mould 8, to form the vamp 1B of basic unit.
When the mould closure, when preparing to be used for injection moulding, nadel portion 4 promptly to lining 6 pressurizations, makes lining 6 interlayers between nadel portion 4 and mold center's part 7, stops synthetic resin to enter this zone.Len req when for this reason, the length of nadel part 4 slightly is shorter than the surface that touches mold center's part 7.Specifically, the amount of needed length shortage when nadel part 4 touches mold center's part equals the thickness of lining 6 by compression the time.This compressed thickness value of lining 6 depends on lining material therefor, lining original thickness and added pressure.When this lining 6 is when making with thin fabric cloth by the synthetic resin cystosepiment of continuous foaming is attached, the thickness when establishing uncompressed is 1.5 to 3.5mm, and the thickness when then compressing fully is generally 0.1 to 1mm.In view of the above, the length of nadel part 4 will be got when being decided to be than its contact mold center part Len req short 0.1 to 1mm.
But, when this a few nadel parts 4 as shown in Figure 6 during extremely thin, then the tip of nadel part 4 just can carry out in the lining 6 when preparing to carry out injection moulding in that mould is closed.Under such situation, the length of nadel part 4 is decided to be greater than contact mold center part 7 with regard to desirable, deducts lining 6 required length during thickness under squeezed state again.Like this, for superfine nadel part 4, Len req in the time of just can making its length be substantially equal to touch mold center's part 7, or promptly for example be that Len req short 0.03 is to 0.5mm when touching mold center's part 7.
When nadel part of closed while of mould 4 was inserted into lining 6, this nadel part 4 was lining 6 and supports reliably, and can prevent its crooked or fracture effectively in injection molten resin injection process.
When the tip that makes nadel part 4 by lining fabric cloth is pressurizeed penetrated the dorsal part of lining 6, nadel part 4 at this moment should be narrower than the braiding mesh of this cloth.When penetrating the front side of lining 6 by the tip that synthetic resin froth bed pressurization is made nadel part 4, nadel part 4 at this moment should be got the identical size of bubble diameter of froth bed therewith, or is narrow than it.
The size of air-vent 3 is determined by the thickness of nadel part 4 on the vamp 1.
More little by nadel part 4 formed air-vent in vamp 1, then air-vent is just more not eye-catching.But,, also can be covered up by layout suitably in the appearance of vamp 1 even air-vent is bigger.For example, on vamp, adopt the exasperate of similar natural leather or the pattern of other pit form, just can make these air-vents 3 be difficult to find out.
Now, the hydrophobic ventilative lining 6 of one deck is set in the inboard of vamp 1,, just can more effectively stops the intrusion of water by this kind lining 6 because the hydrophobic for this reason lining 6 of water repels.In addition, when wearing such footwear walking, pin is just exerted pressure, and lining 6 is compressed to broken line place shown in Figure 8, produces forced ventilation therefrom.Also have, lining 6 has also stoped pin directly to touch and has stopped up air-vent 3, and shown in the arrow of Fig. 8,6 of linings more effectively on vast zone from air-vent 3 air distribution.
The number of air-vent 3 will consider that the number of air-vent 3 and the ventilation of requirement decide on the vamp 1.Air-vent 3 is bigger to ventilate then better, and the ventilation hole count that requires is also fewer.When the diameter of air-vent 3 is 0.2 to 0.6mm and air-vent is for shown in Figure 1 when being opened in footwear anterior, by the ventilative hole count in the 1B of vamp basic unit one side between 5 to 100, and preferably between 7 to 30.
The nadel part 4 that is used to open air-vent 3 is by wire, is for example made by piano wire, have enough intensity to prevent that the process of injecting mould 8 at synthetic resin from deforming.Nadel part 4 is to insert and be fixed in the hole that processes with laser beam or miniature bur in the former shell 5.
When the closed equipment of mould carried out injection moulding, lining 6 was that interlayer is between nadel part 4 and mold center's part 7, in case nadel part 4 directly contacts mold center's part 7.Therefore, lining 6 is whole be along the inner surface of vamp 1 vis-a-vis mold center's part 7 be provided with, not so, it is subtend mold center part setting in corresponding to the zone of nadel part 4 only just.Because lining 6 is entirely along the inner setting of vamp 1, and intermediary's sole 9 is to sew up in the single-piece, becomes the shape that covers pin, this just is easy to when compression molding it is attached on mold center's part 7 provisionally.
Any flaky material that buffering and draught effect can be provided all can be used as the lining 6 that is attached in the 1B of vamp basic unit.In the experiment that the inventor carried out, find lightweight urethane foam with continuous foaming formula, when in addition fabric cloth is attached on its two surfaces as lining again, the best as a result.Adopted thick 1 to 2.5mm urethane foam that sufficient cushioning effect is provided, and will be difficult to tear and long-life more durable cloth is arranged as the lining on the interior table of contact feet, simultaneously with the lining of bigger thin fabric cloth as contact vamp 1.
The polyurethane foam lining 6 that this both sides are attached with the cloth lining has following characteristics: the synthetic resin that is used for forming the 1B of vamp basic unit can not stop up the hole in this kind porous polyurethane foam, and when injection moulding was carried out in the closed preparation of mould, big fabric cloth can allow nadel part 4 penetrate this lining as reliable supporting member smoothly.
Footwear shown in Figure 4 are to make by following mode.Close die after lining 6 being attached on mold center's part 7, synthetic resin is injected in the closed mould 8, to form the 1B of vamp basic unit with air-vent 3 and intermediary's sole 9 as a synthetic resin single-piece, open mould subsequently and take out this single-piece, vamp is covered 1A and is sewn onto on the 1B of vamp basic unit around the cloth of pin mouth, sole 2 is engaged go up at last to finish whole footwear.
In addition, a thin coating can be applied on the outer surface in case of necessity, stop up the sort of little air-vent 3 in order to prevent this coating, the coating that applies is very thin.
