Description

Shoe lift construction

The present invention relates to a kind of shoe lift construction, make that to be located at men's or Socks for woman one-body molded with two resin beds with the facies palmaris of lower end, bring into play remarkable effect at healthy, aspects comfortable and easy to wear.

In recent years, along with consumer demand variation and pursuit health, variation has also taken place in heel structure, and the facies palmaris layer that in the past is contained in the heel lower end is easy to wear, and its replaceability becomes an important topic.Originally use the facies palmaris as women's shoes such as iron hoop, vulcanie,, adopt the good urethane resin of wearability to become main flow recently as the facies palmaris layer material in aspects such as wearability existing problems.But the necessity of replacing does not disappear, and particularly is contained in the facies palmaris of heel lower end such as high-heeled shoes, and it bears the body weight maximum, and area is again little, and therefore wearing and tearing are very serious, change the frequency height.Changed facies palmaris if repair in the shop of not mending shoes will be very difficult, thereby the result causes life-span of goods to shorten in the past.Therefore, even proposed on the public strictly according to the facts clear 63-4407 communique such layman that puts down in writing also can change the heel device of wearing and tearing facies palmaris more simply.

But facies palmaris was no matter whether its replacing was easy in the past, and facies palmaris integral body all is to be shaped to " one thing " with urethanes etc.

Because facies palmaris was to be so that one has produced following problem with same resin forming in the past:

1. facies palmaris is whole when being shaped to one with hard amino acid ethyl ester, and the impact that walking produces on the hard pavement can involve head, healthy and comfortable and easy to wear aspect the user be unsatisfied with.

2. design is gone up in order to produce the stable sensation of step, often adds melanin (passing through carbon black coloring), therefore, tends to stain ground during walking.

3. when considering that healthy aspect reason when one-body molded, exists facies palmaris to tilt to make the danger of pin bending because body weight is in the state of applying in the walking facies palmaris with barras.

The present invention puts forward in view of the above problems, the object of the present invention is to provide a kind of lift construction, by with two-layer tree fat up and down, and select resin with the character that meets various requirement, removable facies palmaris is one-body molded, improve the commodity value of footwear with this.

In order to reach this purpose, be equipped with in the footwear of removable facies palmaris in the heel bottom, form this facies palmaris by two resin beds up and down, a side uses the resin softer than above-mentioned animi resin to form with animi resin, the opposing party in these two resin beds, simultaneously, resin bed forms as one in order to make up and down, therein a square one-tenth conjugate foramen, form bump bonding the opposing party, the present invention is exactly to be the shoe lift construction of feature with above-mentioned.In addition, in this structure, the upper strata can be polyamide resin layer, and lower floor can be the urethane resin layer.

In said structure, facies palmaris forms two-layer up and down, and available resin bed with the character that meets the requirements forms levels.That is, constitute among the levels of facies palmaris, a side uses animi resin, and the opposing party uses than its soft resin and forms, and so owing to the absorption percussion of soft resin layer, can not feed through to head from the impact power on ground, to healthy and beneficial, and wears and feels good.In addition, because the opposing party's hard resin layer, can guarantee that facies palmaris integral body has enough rigidity, also not worrying applying under the body weight state facies palmaris tilts to make situation such as bending to take place, in addition, levels can adopt different color, when making it to use urethanes in lower floor especially, use bright Natural color easily, can prevent to stain ground.

Below, with reference to accompanying drawing, further specify the present invention by description to the embodiment of the invention.

Fig. 5 (a) and (b), (c) are the planes of facies palmaris lower floor of the formation pattern of the various joint boss of expression;

Fig. 6 (a) and (b) are another lift construction embodiment.

Though the footwear of represented embodiment are examples of the footwear used of women among Fig. 1, Fig. 2, the footwear that the male sex uses also are the same.Said footwear are to be made of upper of a shoe 1, the heel 2 that is darted at the rigid plastics system on the bottom surface, upper of a shoe 1 rear portion, the facies palmaris 3 that is installed in two formable layers described later of these footwear 2 lower ends.Heel 2 also separately forms two layers up and down sometimes.

Above-mentioned heel 2 is installed on the bottom surface of upper of a shoe 1 continuously integratedly, is formed with the grooving 4 in inboard lower opening below the heel 2.In addition, below heel 2, offer embedded hole 5 near the central authorities.The prominent metallic pin 6 that is above the horseshoe-shaped facies palmaris 3 embeds in this embedded hole 5 with establishing, and as shown in Figure 2, heel 2 and facies palmaris 3 are combined into one.There is flange 6a metallic pin 6 lower ends, and this flange 6a is located in the facies palmaris 3, make metallic pin 6 and facies palmaris 3 be fixed into one, in addition, in order to improve the metallic pin close property and to prevent the facies palmaris revolution, have some cannelures on the embedded part 6b of metallic pin 6 periphery.Grooving 4 is for the facies palmaris 3 of wearing and tearing is changed convenient design when heel 2 takes off.That is, shown in Fig. 2 double dot dash line, instrument F front ends such as yi word pattern screwdriver are inserted in the grooving 4, facies palmaris 3 is taken off from footwear 2 with this principle.In addition, because grooving 4 is located at the inboard below the heel 2, thereby even without outer surface, seeing from the outside also not can dressed to eh nines, can not diminish the outward appearance of footwear.

The lift construction that the present invention relates to here, is described in detail in detail.

As shown in Figure 2, facies palmaris 3 forms two

layers resin bed

3A, 3B up and down.That is, facies palmaris 3 be not resemble in the past by the formed one thing of a kind of resin, but constituted by upper strata 3A and two resin beds of the 3B of lower floor, levels thickness about equally.For example, a side is by hard polyamide resin layer in the levels, and the opposing party is by forming than its soft urethane resin layer.Levels also can be identical resin bed, and for example levels is all formed by identical urethane.So, when levels is the different resins layer, just is easy to make the levels of facies palmaris to have respectively and requires corresponding engineering properties.Even same resin, also can make the two-layer up and down different hardness etc. that has, why making the softer resin bed of a certain side's employing of levels is because soft resin bed has the absorption impact function, when walking is on the hard pavement, impact and can not involve head, good for health, and feel good when wearing.

In addition, particularly the 3B of lower floor is made of urethane resin, its reason is, the melanin (carbon black coloring) that adopts for the steady sense of generation step tended to stain ground in walking in the past, therefore, lower floor is equipped with urethane resin, utilizes its bright Natural color to prevent that above-mentioned situation from taking place.

A certain side the reasons are as follows in the upper and lower layer: if upper strata 3A and the 3B of lower floor use when soft resin forms as one them equally with the animi resin formation, facies palmaris 3 integral rigidity deficiencies, body weight applies probably meeting run-off the straight under the state in the walking, make the pin bending, by constitute the facies palmaris of half with hard resin layer, just can invest facies palmaris integral body with necessary rigidity, needn't worry above-mentioned situation can take place.

So, facies palmaris is set at two-layer up and down, just can suitably selects to have the character of meeting the requirements resin and use in levels, especially can therefore, can realize having the facies palmaris of complex function polynaryly with different resin bed formation.

The resin bed up and down that forms lift construction of the present invention is not to be combined into one by bonding agent, but form as one by formative stage concavo-convex chimeric as described later.That is, as shown in Figure 2, the some bump bonding 3b above the outstanding resin bed that is formed on the 3B of lower floor are embedded in the conjugate foramen 3a that the resin bed of upper strata 3A forms and are combined into one.Adopt the reasons are as follows of this integrated structure: when levels is the urethane resin layer, also considered to utilize its bonding formedness to be combined into one, and had flash from bonding plane under this occasion and form degraded appearance by bonding agent; In addition, even the material of the cementability difference as nylon resin also can be as the resin that constitutes facies palmaris.

Lift construction of the present invention can be made by injection molding as mentioned above.Here according to Fig. 3 (a)-(d) forming method of this facies palmaris once is described.

Shown in Fig. 3 (a), the inboard has in advance above-mentioned metallic pin 6 to be settled on the metal pattern (former) 7 of platform shape section projection 7a and is fixed on desired location, sets up formpiston 8, forms the die cavity 3A ' that should become the facies palmaris upper strata in metal pattern.And behind the matched moulds, inject the molten resin of setting (for example urethane resin) from inlet.At this moment the flange part 6a of molten resin metallic pin 6 and the gap between the metal pattern 7 also can arrive, and form metallic pin 6 and are embedded in fixing state.Through the operation of setting, the moulding product on facies palmaris upper strata are taken out in die sinking after the resin bonded.Be provided with the trapezoid space of back draught in the part of these moulding product, i.e. conjugate foramen 3a.

Shown in Fig. 3 (b), these moulding product that are equivalent to the facies palmaris upper strata are installed in another metal former 9, formpiston 8 equally closes.

Shown in Fig. 3 (c), so in this metal pattern, formed the die cavity 3B ' that is used for forming facies palmaris lower floor.Behind the matched moulds, molten resin (for example nylon resin) is injected from inlet.The conjugate foramen 3a of formed back taper trapezoid cross section also can be by the filling of nylon resin institute on the resin of upper strata.After injecting resin bonded, the moulding product are taken out in die sinking, just can obtain facies palmaris moulding product of the present invention shown in Fig. 3 (d).

Because above-mentioned conjugate foramen 3a forms down terraced cross section, so a filling lower-layer resin is deformed into the bump bonding 3b of back taper, the 3B of lower floor resin bed integrally formed inseparably (joint) is on the 3A resin bed of upper strata.In this lift construction, but the conjugate foramen 3a of molding is a through hole.Enter the shape of bump bonding 3b of conjugate foramen 3a and configuration as shown in Figure 4, make coniform or the protruding 3b of mushroom is formed on and is on the horseshoe-shaped lower floor 3B surface, can form 3 or 4 according to its surface area difference.In addition, as shown in Figure 5, also can form the continuous protruding 3b of U font or form vertical or horizontal two protruding 3b in the place of the flange 6a that avoids metallic pin 6.

If use the combination metal pattern, make molding become possibility, so as shown in Figure 6, even not resembling, conjugate foramen do not connect the foregoing description, facies palmaris also can be bonded into one, and Fig. 6 (a) is the example of screw head projection 3b, and Fig. 6 (b) is the example of wart like structure 3b, which kind of is all the same with the foregoing description, and levels can not separated.

According to the present invention described above, has following effect.

1. with two-layer formation facies palmaris up and down, can select respectively to have the resin dispensing levels of character of meeting the requirements. That is, make that a side uses animi resin in the levels that consists of facies palmaris. The opposing party uses than barras and forms, and can guarantee that facies palmaris integral body has enough rigidity on the one hand, and the impact from ground can not involve head on the one hand, can obtain healthy upper, dress and sensuously be good lift construction.

2. can make levels is different color, particularly when lower floor forms with urethane resin, can utilize its bright Natural color, can prevent from staiing ground.

3. double-deck lift construction of the present invention can form as one as injection-molded article, so the crudy fineness of facies palmaris can obtain the high goods of commodity value.
