Description

Shoe with heat isolating structure

What the present invention relates to is the article of footwear field, such as leather shoes, and high boots, the footwear of high side leather shoes and the like the objective of the invention is to recommend out a kind of footwear that have heat insulation structural.

At present, a lot of people are arranged, particularly those often are engaged in the people of industrial work, and they wear general footwear or similar city shoe and working without cessation for a long time, walk about, and often be to continue eight hours even more longer time.Consequently, heavy then be easy to be caught the foot epidermis that fungi or other parasite cause and infect, or make foot plate surface that the decortication phenomenon take place; Light then also can cause burn feeling or other uncomfortable feeling of foot.Particularly those foots are easy to a large amount of people that perspire, and concerning them, suffer untold misery especially.

At present the solution that adopts usually of footwear industry producer institute is assigned address on the upper of a shoe jewel hole that punches, particularly in the front portion of footwear.

But, the result of this solution and unsatisfactory.Because at first, it can not make under the sole, and particularly toe position and toe back puts forth effort the effect that the position forms circulation of air or plays ventilation; Secondly, also can not make the heat that is produced in foot plate surface and the traveling process isolated.

Yet those but cause the very high foot incidence of disease at large by the article of footwear that wear-resisting sole and the direct mold pressing of upper of a shoe form, and clearly produce uncomfortable sensation.

Purpose of the present invention just is to improve existing footwear weak point in this respect.

In fact, face all was equipped with one deck heat insulation structural under the outstanding feature of the footwear that the present invention introduced was they interior.

That is to say that the present invention proposes a kind of shoes, is characterized in that: it in ground floor the end below heat insulation structural is housed.

Heat insulation structural preferably is made of microscler extension component, and its optimum position is arranged on below wearer's the support zone of sole at least, and face is vacated a plenum space at least under interior.

Elongated member with the form of pasting pad by it the edge with weldering press, method gluing or that sew up is fixed on the inner surface at the interior end, and isolated part it and the interior end be housed limit some plenum spaces jointly.

Isolated part preferably adopts the form of cross rib.

Isolated part is along the y direction horizontal spreading of microscler extension component.

Isolated part also can vertically launch abreast along the y direction of elongated member.

Be the blocking-up that the isolated part of cross rib shape preferably is furnished with at least one shape that cracks, it with the adjacent plenum space that separates by isolated part or cross rib before and after be connected and communicate.

With boring whole or in part at the end in the ground floor, it is distributed in by above the plenum space that isolated part or cross rib separated that designs on the elongated member.

Can fill deodorizing solid matter with long-acting or desiccant-filled in the plenum space that forms between the end and the elongated member in the ground floor.

Elongated member is designed to have on the one hand last enclosure portion, and it and following enclosure portion constitute a flat capsule bag jointly; Also can be mounted with an inlet valve and a pressurization gas valve on the other hand, inlet valve is open-minded respectively with the pressurization gas valve, inlet valve can be positioned at the outer or inner of shoes, and the pressurization gas valve is placed under the sole with the form of tubule and/or under the toe, even can be placed near the heel of footwear.

Its heat insulation structural combines with the air circulation pump that is placed in the spring heel part, and this air circulation pump communicates with the plenum space that elongated member is limited by a passage, and this pump can be drawn outer air of footwear or the air in the footwear.

By detailed description to following non-limiting embodiment, and note with reference to the accompanying drawings, you will more clearly understand design philosophy of the present invention.This paper is only with a width of cloth (Fig. 1) with reference to the accompanying drawings, and it is the part section side-looking schematic diagram directly perceived of the footwear made according to design philosophy of the present invention.

Footwear 1 described in the accompanying drawing are by the wear-resisting end 2, the end 3 in the ground floor, and upper of a shoe 4 constitutes.

According to the present invention, this footwear particularly advantageously are equipped with one deck heat insulation structural 5, it be positioned at the end 3 below.

Heat insulation structural 5 preferably is made up of a microscler extension component 6, and it preferably is positioned at the support zone below in wearer vola, and reserves a specific plenum space below the interior end 3 at least.

This extension component 6 is fixed on the surface, inside at the interior end 3 by its edge 7 usefulness weldering pressure, method gluing or that sew up with the form of subsides pad, will there be isolated part 8 centre, isolated part preferably adopts the form of cross rib, so that leave certain space for air pasting at the pad and the interior end 3.

According to characteristics of the present invention, the isolated part 8 that the centre includes is along the longitudinal axis longitudinal direction horizontal spreading of microscler extension component 6, like this, just guaranteed the pliability on microscler extension component 6 vertically, thereby the pliability of integral body that makes footwear is without any problem.The bending that is produced in advancing can only make the geometric space between the cross rib 8 change.

Simultaneously, also have a kind of like this possibility, implement modification according to of the present invention another, isolated part 8 can parallel with the longitudinal axis of microscler extension component 6.

In order to improve the pliability of microscler extension component 6, the isolated part 8 that is the cross rib shape preferably is furnished with the blocking part of the shape that cracks at least, so that link to each other before and after the contiguous plenum space that separates by isolated part 8 or by cross rib and communicate.

According to the present invention, heat insulation structural 5 can under sole, produce one isolate air bag and when making sole and advancing the wear-resisting end 2 and in the ends 3 rub and produced hot isolated.

According to another characteristics of the present invention, will be drilled to hole 9 on the surface at the interior end 3 whole or in part, be distributed on the microscler extension component 6 by above isolated part 8 or the plenum space that cross rib separated.Like this, when each flexure operation in advancing took place, the air in being present at the end 3 and the wear-resisting end 2 just can be overflowed by the boring at the interior end 9, sucks ozone again in isolated part 8 simultaneously after flexure operation takes place.

In addition, this heat insulation structural 5 also can reduce the degree of crook and the respective thickness aspect structure 5 thereof at the wear-resisting end in the design.The result who is produced is like this: in the injection moulding process at the wear-resisting end, and when for example using the polyurethanes injection moulding, can its consumption of corresponding minimizing.

According to another characteristics of the present invention, the plenum space between the interior end 3 and the microscler extension component 6 can partly be packed into and be had the solid matter of long-acting deodorization effect or long-acting drier.So just, can solve the problem of perspiring and correspondingly producing peculiar smell simultaneously.

Implement modification according to of the present invention another, this does not introduce in the accompanying drawings.Elongated member 6 can be designed to have on the one hand the enclosure portion above, and the flat capsule bag in it and the common formation of following part can also have an inlet valve and a pressurized delivered valve on the other hand.These two kinds of valves communicate with each other, and inlet valve is positioned at the inside of shoes, and the pressurized delivered valve is positioned at the outside of shoes, are placed in below the sole or below the toe with the form of tubule, even can also be placed near the heel of a shoe.This enforcement modification can make shoes in the process of walking the heat-blocking action of isolation structure 5 and air circulation effect and gas exchange action be combined.

When the wearer of footwear moves, in the wearer acts on the pressure of pin at the end 3, the end 3 when bending in making simultaneously, do the time spent when the various pressure of wearer's pin, will show particularly significantly by air circulation effect and the gas exchange action of settling isolation structure 5 to produce.

Sole down or the air below the toe distribute and gather the mode that can pass through tubule, groove or grooving and assemble to needed position.

Implement modification according to of the present invention another, this is not described in the accompanying drawings yet.Also isolation structure 5 and the air circulation pump that is placed in the spring heel part might be combined simultaneously.This air circulation pump communicates with the air space that elongated member 6 is limited by a passage, and this pump can be drawn air and the outer air of footwear in the footwear.Like this, just may realize the enforceable air circulation of a kind of shoes inside.Like this, whether no matter the renewal of air arranged, can discharge air under the sole and/or under the toe by aperture 9.

Polyurethane foam can be adopted in the wear-resisting end 2, can advise adopting the single layer structure or the sandwich construction of different densities according to different needs.

Benefit from the present invention, we can produce a kind of new-type shoes, it not only can be with that the heat that friction produces takes place between the end and the wear-resisting end in making be isolated in sole and the walking and because of walking, simultaneously, also may make under the sole and toe under maintenance ventilated.In addition, the present invention also provides simultaneously and has oozed out and the processing method of deodorizing.Consequently make the wearer of footwear feel especially comfortable, also weakened the possibility that infects foot affliction simultaneously widely.

Certainly, the present invention is not limited to described in the accompanying drawing and that a kind of embodiment of introducing.When not exceeding institute of the present invention protection domain, a variety of improving one's methods can also be arranged.Particularly aspect the making material of footwear, can adopt more suitable easy material to substitute original material.
