Description

Trouble-saving shoe-pad

The present invention relates to a kind of trouble-saving shoe-pad.

In the context of the present invention, trouble-saving shoe-pad can be regarded as have machinery, the shoe-pad of chemistry and physical characteristic, it can be avoided because the user that the sharp objects perforation causes is seriously injured.

More particularly, for trouble-saving shoe-pad, it means the nail of 4.5mm diameter or larger diameter, vertically hammers into shoe-pad with the speed of about per minute 10mm, and shoe-pad can not passed, and the power that shoe-pad stops reaches 1100 newton.Such value basic with prevent accident in compulsory regulation requirement consistent.

Trouble-saving shoe-pad is made up of the sheet metal of suitable shape basically in the prior art.

This thin slice is inserted in the shoe-pad of personal protection footwear, between the sole of ground and user's dress.More particularly, trouble-saving shoe-pad of the prior art is arranged in the little space in the sole of footwear, in plastic material, remains on the operating position by introduce packing material in the gap of sole after its objective is usually.

By this way, when user's pin accident steps down on nail or the other similar object, nail penetrates sole, and is stoped by the metal material in the shoe-pad, has avoided nail to arrive user's sole, therefore avoids serious injury.

The applicant finds that trouble-saving shoe-pad can improve at different aspect in the prior art.

At first, the degree of trouble-saving shoe-pad of the prior art protection that the user is provided always can't be satisfactory.

In fact, may penetrate sole such as sharp objects such as nails and arrive user's pin and do not run into the prevention of sole.Such incident because the metal shoe-pad can not stop the nail with respect to the inclination of the plane that limited by shoe-pad laterally to penetrate sole, causes damage to the user inevitably, that is to say that it is not tackled by the metal shoe-pad, still can arrive user's pin.

In fact, because the metal shoe-pad must be inserted in the sole, trace, i.e. the plane projection of metal shoe-pad is always little than the footwear seal, to guarantee that shoe-pad can not break away from sole when walking.In other words, in the rear end of the rear end of footwear and metal shoe-pad, at the front end of the front end of footwear and metal shoe-pad, always between the side of the side of footwear and metal shoe-pad have a space.When nail enters these spaces, it is not subjected to any interception and arrives user's pin.

In addition, as previously mentioned, the metal shoe-pad need be inserted and in the gap that is fit to up to filler is inserted in this gap and closed shoe-pad equally.Usually, be difficult to carry out closure in the operating position of metal shoe-pad, and be not success always, reason is in the time that packing material is inserted that requires, and can only handle and be placed in the gap shoe-pad in little space.

In this article, major technique task of the present invention is to propose a kind of shoe-pad of preventing accident that overcomes above-mentioned defective.

Especially, the purpose of this invention is to provide a kind of shoe-pad of preventing accident, can tackle sharp objects independently from the perforation direction of personal protection sole.

The present invention's purpose further provides a kind of shoe-pad of preventing accident, can be easily and carry out personal protection apace.

By the technical characterictic of the shoe-pad of preventing accident of the present invention, basic technical assignment and the specific purpose that realizes narration.

By a preferred non-exclusive embodiment of the shoe-pad of preventing accident, further aspect of the present invention and advantage are more clear, and this embodiment is indicative thereby is nonrestrictive, as shown in the drawing, and wherein:

Fig. 1 is the section view that is arranged on the shoe-pad of preventing accident in the personal protection footwear according to the present invention;

Fig. 2 is the section along the II-II face of shoe-pad among Fig. 1;

Fig. 3 is another embodiment of shoe-pad section among Fig. 2; With

Fig. 4 is another embodiment of shoe-pad among Fig. 3.

With reference to the accompanying drawings, Fig. 1 shows generally according to accident shoe-pad of the present invention.

In the context of the present invention, need to prove that the shoe-pad of preventing accident is understood that, can withstand sharp objects and the shoe-pad that do not passed.Particularly, preventing accident that shoe-pad refers to not can be that the nail that the power with 1100N of 4.5mm or larger diameter vertically enters in the shoe-pad passes by diameter.Shoe-pad 1 comprises bottom surface 2 and the end face 3 relative with bottom surface 2.

Shoe-pad 1 is made up of multiply cloth 4, can pass bottom surface 2 to end face 3, and vice versa.On the upper of a shoe 101 that is sewn directly to footwear 100, use diameter vertically to penetrate into shoe-pad 1 with 90N external force at least, preferably employing phase wound Bel's technology (Strobel technique) less than the pin of 14/10mm.

Particularly, can pass bottom surface 2 to end face 3 and the shoe-pad 1 that vice versa, be the pin of 14/10mm-2/10mm by diameter, and preferred diameter is 12/10-8/10mm, and more preferably diameter is the pin of 11/10mm, vertically penetrates in the shoe-pad 1 with 90N external force at least.

In addition, the pin of above-mentioned size passes external force that shoe-pad has between 90N-400N before having, preferably between 100N-300N, and more preferably between 150N-250N, 200N particularly.

By this way, advantageously, any nail of footwear 100 soles 102 of for example entering because step on, before it arrives user's pin, shoe-pad 1 can be individually angle at the bottom of the nail transpierce shoe stop them.

In addition, this shoe-pad of preventing accident can directly be sewn on the upper of a shoe of footwear, can reduce the production cost of personal protection footwear significantly, because need not carry out complicated location to shoe-pad in sole.

As previously mentioned, object shoe-pad 1 of the present invention can be by size less than 14/10mm, and the pin of preferred above mentioned dimensions passes, and allows to adopt this wound Bel technology that it is sewn onto on the upper of a shoe.For this purpose, should be noted that and pass shoe-pad 1 desired diameter and power is the function of shoe-pad 1 thickness.Under any circumstance, shoe-pad 1 can be passed by pin commonly used, and it is subjected to using the sewing machine of this wound Bel technology, the power that the sewing machine on the promptly common upper of a shoe that shoe-pad directly is sewn into footwear applies.This feature allows further to reduce the production cost of personal protection footwear, because do not need special sewing technology, uses that good and inveteracy sewing technology and sewing machine (this creates Bel) are enough in the shoe-making industry.

In addition, shoe-pad 1 can advantageously be cut and straight forming by using traditional model by Shoes Factory, has guaranteed the optimization of warehouse space.In fact, do not need to comprise the warehouse of moulding sole, but can cut and the moulding sole according to the shape and size of being strict with according to multiple shape and size setting.

In addition, shoe-pad 1 is made up of multiply cloth, has guaranteed that the damping trap is higher than at the bottom of the Metal shoes, and has increased the comfort level of footwear.

It is emphasized that from protection user's sole angle in fact shoe-pad 1 can be passed less than the pin of 14/10mm by diameter and be actually unessential.In fact, as a rule, the length of nail is the function of diameter basically, and diameter is less than the very difficult sole that arrives the user of the nail of 14/10mm, because their curtailment is to pass the thickness of sole.

In each case, do not consider the injury of diameter less than the nail of 14/10mm, because they can not cause tangible injury to the user, diameter is that 4.5mm or bigger nail are opposite.

From the angle of structure, described before shoe-pad 1 is made up of multiply cloth 4.Each layer 5 of multiply cloth 4 comprises tissue layer 6 and at least one resin surface layer 7.Can predict this latter and be positioned on each tissue layer 6, and only cover its surface, promptly resin surface layer 7 is not to tissue layer 6 infiltrations.

Resin surface layer 7 is made up of polyurethane and/or allyl resin, this polyurethane and/or allyl resin be rich in be selected from comprise silicate, particularly ferrosilite, alum clay, silica, ceramic material, based on the material of the material of glass.

Advantageously, these materials are relevant with resin on grain shape, generally have the diameter of 1/10-1mm.

As previously mentioned, resin surface layer 7 deeply is not penetrated in the tissue layer 6, and has than the thickness of tissue layer 6 to 10 times thickness when young.

Advantageously, resin surface layer 7 has strengthened the compactness of tissue layer 6, because it has limited towards by the yarn on the surface of the moistening tissue layer 6 of resin bed 7.In addition, it deeply is not penetrated in the tissue layer 6 exactly because it is emphasized that resin surface layer 7, thereby has guaranteed the flexibility of shoe-pad 1 the best.

This back one feature, promptly the flexibility of shoe-pad 1 is very important, because it has guaranteed the lasting service life of sole.

In fact, stand bend cycles several times, can see that it is still quite complete, and rupture at the bottom of experiencing 10 trouble-saving Metal shoes that circulate by making shoe-pad 1.

Advantageously, resin surface layer 7 is not applied on the outer surface with the contacted multiply cloth 4 of user's sole.

This feature allows shoe-pad 1 more comfortable, guarantees that preferably there are enough moisture absorption rates and desorption efficiency in shoe-pad 1 zone relative with user's sole, and its result is more obvious hereinafter.

For tissue layer 6, different with the line that first or second type is used, it is made up of the weave that interweaves, and promptly the weft yarn of predetermined pattern and warp thread are just so-called two-sided.Double knitting should mean it is the braiding that interweaves, and with respect to its lower surface, the end face of the fabric that the braiding that interweaves obtains is asymmetric, or is not the double knitting of mirror image; Double knitting is for example implemented through its a single continuous warp thread by arranging by two continuous weft yarns with according to predetermined pattern.

Advantageously, by increasing the compactness of tissue layer 6 itself, double knitting allows to increase the density of weft yarn (weft), and this density is the number of the weft yarn in every centimetre in the tissue layer 6.Highdensity weft yarn has guaranteed large scale, promptly is equal to or greater than the nail of 4.5mm, and the infall that is maintained at one or more weft yarns and warp thread is up to weft yarn and warp thread oneself fracture or be removed.In fact, when it appears under the situation that sheet metal limits, the density of weft yarn is not unlimited, and the pin that guarantee to have specific dimensions can pass sole 1 and can be made.

Double knitting further allows to increase the coverage of terminal fabric, and promptly for terminal fabric, it allows to increase by the effective area that covers of fabric and the ratio of standard area.

Further, pointed out that 7 pairs of coverage effects of resin surface layer contribute.In fact, as illustrating that resin surface layer 7 has increased covering significantly among the embodiment 1 hereinafter.

Covering to multiply cloth 4 is important feature, because it has directly guaranteed interception sharp objects, for example nail.In fact, coverage effect is big more, and interception is big more with respect to the possibility of the nail that sole is exerted pressure.The contribution of 7 pairs of coverage effects of resin surface layer is applied to the extracting on the path of nail and keeps being used for assurance by the particle that is rich in the resin.

In fact, the covering of multiply cloth 4 is not whole (referring to embodiment 1), and the pin that causes diameter to be equal to or less than 14/10mm to small part passes shoe-pad 1 possibility, but can prevent the nail of diameter more than or equal to 4.5mm.

The weft yarn of tissue layer 6 and warp thread comprise non-aramid fibre (non aramidic fibers).This feature can reduce the production cost of shoe-pad 1 significantly, because well-known, aromatic polyamides is expensive and be not easy to have bought from the market.

Yet, it is emphasized that the meaning of above-mentioned explanation, in above-mentioned description, shoe-pad 1 has trouble-saving feature, below will be to better explaining except that aromatic polyamides.In first embodiment, shown in Fig. 2 and 3, all tissue layer 6 are made up of the PE yarn of high tenacity basically, preferred 1100 standard dtex (nominal dtex).More preferably, every yarns is made up of the many fine rules that tangle continuously, preferred 200, twists with the fingers (twist) for preferred every meter 60.

In second embodiment, as shown in Figure 4, some tissue layer 6 are made up of the PE yarn of high tenacity basically, and it has the standard fiber number that is lower than the first embodiment yarn, preferred 238 standard dtex.More particularly, each yarn is made up of a plurality of filaments that tangle continuously, preferred 48, twists with the fingers for preferred every meter 120.In other words, in a second embodiment, tissue layer 6 is two kinds of different types.Particularly, the first kind can be predicted and have size and the toughness bigger than second type.

In addition, in first embodiment, use the embodiment greater than the size and the toughness of the second embodiment filament, every centimetre in fabric comprises that the warp thread of 27 to 31 weft yarns and every centimetre 20 to 24 is predictable.

In a second embodiment, tissue layer 6 comprises every centimetre of 90 to 92 warp thread of fabric and every centimetre of 32 to 36 weft yarns.

The yarn that uses among the foreseeable selection embodiment is selected from comprising that the material of polypropylene, polyamide, polyamide (polyamides), polyethylene (polyethylene), polyvinyl (polyvyinyl), artificial silk group makes.

Advantageously, the outside of tissue layer 6 preferably with the tissue layer 6a of the contacted multiply cloth 4 of user's sole, comprises the long filament of cellulosic material, the silk of preferred cotton, and purpose is to absorb and the eliminating moisture.Like this, guaranteed the high degree of comfort of trouble-saving sole 1, because it allows user's pin nature perspire.Other cellulosic material that uses can be linen, fiber crops and artificial cellulose.

Particularly in the braiding that interweaves, introduce the filament of cellulosic material, in the mode that replaces with respect to the braiding that interweaves of the above-mentioned yarn of mentioning.The filament that cellulosic material is made and form alternately depending between the yarn interlaced and wish the trap and the desorb degree that reach.In a preferred embodiment, can predict this alternately is the yarn that a cellulosic material is arranged in per three parallels.

It should be noted that the cellulosic material silk does not change the reason of the trouble-saving feature of shoe-pad 1 basically, points out among the embodiment 2 that will be described hereinafter.

In addition, except having cellulosic material, multiply cloth 4 tissue layer 6 comprises a plurality of monofilaments of being made by conductive material at least.The monofilament of every conductive material tangles at the outer surface of weft yarn or warp thread.In other words, by default conductive material fibril on some weft yarns or warp thread, shoe-pad 1 becomes to conduct electricity and also can eliminate electrostatic charge, avoids potential adventurous electrostatic charge to accumulate.

Advantageously, effectively real in order to ensure the fibril of conductive material, at every 20-80 bar warp thread, the warp thread fibril in preferred per 23 warp thread is introduced the latter, at every 20-80 bar weft yarn, introduces the latter in two continuous weft yarns of preferred per 28 weft yarns.The fact of introducing the fibril of two conductive materials in two continuous weft yarns makes it possible to realize the conductive network structure in shoe-pad 1.In fact, as preceding mentioning, because the braiding of each layer fabric 6 all is two-sided, just has double-deck weft yarn, two conductive material fibrils introducing in two continuous weft yarns are guaranteed electrically contacting between weft yarn and the warp thread, the relative position in the fabric of warp thread that is rich in conductive material and weft yarn interweaves.

In a preferred embodiment, this conductive material fibril comprises the carbon monofilament with 24dtex standard fiber number.

The example of validity of the fibril of this conductive material has been shown in example 3.

As noted, irrelevant with cellulosic material that exists and conductive material, cellulosic material and conductive material can significantly not change the trouble-saving performance of shoe-pad 1, by predicting one by at least four layer of 5 multiply cloth that constitutes 4, every layer comprises a tissue layer 6 and a resin surface layer 7, the trouble-saving performance that the conductive material realization is mentioned.This configuration is shown in Figure 2.

The trouble-saving performance of having noticed further minimizing tissue layer 6 in surprise and not damaged shoe-pad 1 is possible, but has advantageously reduced weight and production cost.In fact, as shown in Figure 3, can utilize multiply cloth 4 to finish shoe-pad 1, multiply cloth 4 comprises three layers 5, especially a first surface or last layer 5a, second an end layer 5b relative with the first end layer and an intermediate layer 5c who is included between the first last layer 5a and the second end layer 5b.

Advantageously, three layers of 5a, 5b that mention, two-layer at least 5b, 5c among the 5c comprise a tissue layer 6 and two resin surface layers 7 for every layer.

These two latter are arranged on the opposite face of tissue layer 6.

By example 4 as can be seen, the effect that produces of two resin surface layers on two tissue layer 67 is not damage the trouble-saving performance of shoe-pad 1 in order to remove layer 5 from multilayer 4.

This effect is surprising, because can see in example 4, if compare with the one deck in the tissue layer 6, the effect of considering the performance of preventing accident of resin surface layer 7 separately almost is inappreciable.

But how the existence of two additional resin superficial layers 7 can replace tissue layer 6 basically as can be seen.

First embodiment that both can be applicable to mentioned above also can be applicable to second embodiment.

Must emphasize that second above-mentioned embodiment further guaranteed the realization of considerable advantage.

In fact, comprise the tissue layer 6 of closeer braiding of 31 weft yarns of every centimetre of fabric and 24 warp thread and the use of thin fibril by prediction, can stop diameter to be lower than the penetrating of nail of the size of 4.5mm.

Especially, comprise by prediction in five layer 54, five layer 5 of the multilayer at least that treble cloths 6 is to describe with reference to first embodiment at least, two-layer at least fabric 6 be with reference to second embodiment description, except the nail of diameter 4.5mm, shoe-pad 1 can also stop the penetrating of nail of diameter 2.5mm.This nail is with between the 300N to 700N, and preferably between 400N to 600N, more preferably the power of 550N hammers into shoe-pad.More preferably, as what in example 5, report, by predicting two continuous tissue layer 6, this two tissue layer 6 are made of fibril, preferably make by polyester, have the toughness of 238 standard dtex and have a two-sided braiding that interweaves, the fibril that the two-sided braiding that interweaves is thicker than use 1100 standard dtex toughness is woven.Will be by three layers of continuous tissue layer 6 combination of the type of 1100 standard dtex fibrils, when with between the 300N to 700N, between the preferred 400N to 600N, when more preferably the power of 550N hammered into shoe-pad, the nail that diameter is equal to or greater than 2.5mm can not pass shoe-pad.

For example, five layers of tissue layer 6 by adopting every layer to have the fibril of 1100 standard dtex although the proportion of this tissue layer 6 is bigger, can't realize this effect.In fact, it must be emphasized that, fifty-fifty, multilayer 1 proportion that comprises five layers of tissue layer 6 of every layer of fibril with 1100 standard dtex be about 3300 grams/square metre, and the multilayer with treble cloths 6 that the two-layer fabrics 6 of every layer of fibril that comprises 238 standard dtex and every layer is made up of the fibril of 1100 standard dtex have proportion be about 2900 restrain/square metre.

In order to realize shoe-pad 1 trouble-saving target of the present invention, a kind of suitable method is to preset the weft yarn and the warp thread of the non-aromatic polyamides material that interweaves according to predetermined double knitting, in order to obtain a single tissue layer 6, coating resin layer 7 at least one face of the single tissue layer of obtaining 6, and at least three layers of tissue layer 6 that has resin bed 7 at least one face are combined tightly, be used to obtain multilayer 4.

Advantageously, before coating resin superficial layer 7 on the tissue layer 6, for the hydrophilic fabrics layer 6 of the yarn that increases fabric 6 through handling, the yarn of fabric 6 will be surrounded by resin bed 7.

Like this, the resin that forms resin surface layer 7 is attached to tissue layer 6 better, guarantees that the parallel of fabric 6 and warp keep their configuration forcefully.

And, it must be emphasized that, with respect to identical untreated fabric 6, can on fabric 6, use more substantial resin effectively to the fibril hydrophilic treated of fabric 6.

In a preferred embodiment, hydrophilic processing is to realize by the surface of fabric 6 being carried out plasma treatment to the fibril of fabric 6.Especially, be subjected to plasma discharge, be changed owing to form the chemical bond of material on the surface of fabric 6, thereby increase the trap of this surface the resin of resin surface layer 7 by the surface that makes the fabric 6 of accepting resin surface layer 7.

This plasma treatment is preferably carried out in the atmosphere of nitrogen or carbon dioxide purification.

In addition, advantageously, before applying resin surface layer 7, handle the surface of fabric 6, improved the validity that nail penetrates, as shown in the example 6 of hereinafter report by utilizing identical hydrophily.

In a preferred embodiment, by carry out the application step of the resin surface layer 7 on the tissue layer 6 at the resin of using 45-85 gram fluid state on every square metre of tissue layer 6.By use can homogeneous distribution resin cutter, this coating prediction fluid resin that on tissue layer, distributes equably.Preferably, when tissue layer 6 when it rolls by transmission down, this cutter held stationary.

When tissue layer 6 even coating resin, the layer 5 that obtains for example passes through in the stove at a drier, with dry resin and make it and tissue layer 6 combines.

Handling in advance under the situation of tissue layer 6 for the surface hydrophilic that makes tissue layer 6, the deposition of resin bed 7 must be finished in 72 hours after described processing.

In fact, we have been noted that when missing during this period of time, the surface of tissue layer 6 has just lost its hydrophilicity.

All under the situation of coating resin superficial layer 7, the tissue layer 6 that has had dry resin superficial layer 7 can reverse easily fully, and repeats above-mentioned coating and drying process on the layer 5 that obtains on the two sides of tissue layer.

Layer 5 step that couples together securely that obtain are included in the thermoplastic material that applies several micron thickness at zero point between layer 5 and subsequent the sheet.Have put into the heat-stabilized wood tablet layer 5 by heated bucket, relative with resistant to elevated temperatures malthoid blanket, this malthoid blanket combines in order to heat of fusion plastic tablet and with the different layers 5 of fabric multilayer 4.

It is emphasized that the heat-stabilized wood tablet almost is negligible to the contribution of the performance of preventing accident of shoe-pad 1.As unique effect, it provides the layer 5 that will form multiply cloth 4 to combine.
