Description

a new type of shoe

technical field

The utility model relates to a daily necessities shoe, in particular to a novel shoe with a cup-shaped insole and sole shape.

Background technique

The shoes of the present prior art should have shock absorption function when touching the ground, to reduce the load applied on the pin. In addition, the shoes should not fatigue the wearer, even after prolonged wear. Therefore, we hope that the shape of the insole conforms to the shape of each person's sole to avoid disrupting the balance of the human body. For example, some shoes use spongy materials as insoles, and the insoles can change shape according to the weight of the wearer to achieve comfortable wearing. In addition, thermoplastic resin can be used instead of the sole material to define the sole shape. Before the shoes are used, the foot mold is put into heated thermoplastic resin for shaping.

Let's take a look at the first embodiment first: the insole material that can keep its shape after repeated deformation has not been disclosed yet; while the second embodiment requires that the thermoplastic resin of the insole be heated before using the shoes, Thereby changing its shape to match the shape of the sole of the foot. This method requires a certain amount of time and labor.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a shape forming of the soles of shoes and cup-shaped insoles, so that the shapes can be easily maintained when deformed due to weight.

The technical scheme of the purpose of the invention of the utility model is as follows:

A new type of shoes, including insole, heel, support layer, cuff, barrier layer, sole, said insole includes a middle cushion layer made of resin foam and a covering layer covering the outer surface of the middle cushion part . Resin foam is a foam resin synthetic material, which contains low-density polyethylene A, ethylene-vinyl acetate copolymer B, filler C, blowing agent D and crosslinking agent E. The sole of the foot is pressed against the cover, and the weight of the human body on the sole causes the air bubbles in the resin foam to be squeezed and plastically deformed along the shape of the sole.

The shape of the sole is shaped, including a plate support layer whose shape is the same as that of the middle cushion layer in plan view. The plank support layer is under but stiffer than the middle backing layer. The plank support layer provides support for the middle pad layer. The covering layer covers the middle pad layer, and the bonding surfaces between the middle pad layer and the support layer are bonded by adhesive.

The covering layer should at least cover the upper surface of the intermediate cushion layer, and the bonding surface between the intermediate cushion layer and the support layer is bonded with glue. Corresponding to the junction between the heel and the mid-cushion layer and the support layer or between the support layer and the outsole arch, a barrier is raised toward the cover to resist movement of the heel.

The plate support layer is arranged under the middle pad layer but is harder than the middle pad layer to provide support for the middle pad layer. The covering layer includes an inwardly folded cuff beneath the support layer. The covering layer covers the upper surface of the intermediate pad layer, and the bonding surface between the flanging of the covering layer and the support layer is glued.

Compared with the prior art, the utility model adopting the above-mentioned technical solution has the advantage that: since the middle liner layer in the insole is made of resin foam and has high moldability, even if the shoe is taken off by external force, After removal, the upper surface of the insole still maintains the shape of the heel. Thus, in a relatively short period of time (eg, approximately 3 hours), a shoe sample can be used to mold an individual heel shape onto the surface of the insole. In this way, it is possible to save time and effort to manufacture shoes suitable for each person's sole shape.

Detailed ways

Further illustrate below in conjunction with accompanying drawing how the utility model is realized

As shown in Figure 1, the resin base 1 forms the framework of the resin foam a, which is composed of low-density polyethylene A and ethylene-vinyl acetate copolymer B, and is cross-linked by a cross-linking agent E. The mass ratio between the low-density polyethylene A and the ethylene-vinyl acetate copolymer B is set to A/B=95/5～90/10, because in the characteristics of the compressive residual strain rate that will be mentioned later, when When the mass ratio of low-density polyethylene A is less than 90/10, the compressive residual strain rate becomes small. Therefore, the shape retention ability after deformation under the action of external force will decrease, and, when the mass ratio of low-density polyethylene A is higher than 95/5, the decrease in tensile strength will be exacerbated, and the shape will be easily destroyed. Add Filler 2 Filler C to adjust the hardness of resin foam a. The material can be selected, and the amount added can be adjusted according to the application.

The air bubbles 3 are formed in a closed cell state by foaming with a foaming agent during the production process of the resin foam.

Next, the production method of the resin foam a will be described:

First, mix low-density polyethylene A, ethylene-vinyl acetate copolymer B, filler C, foaming agent D and crosslinking agent E in a predetermined ratio, and knead them sufficiently to form a resin composite.

The mixed resin composition needs to be foamed at a constant temperature of 140° C. to 180° C. and molded to conform to a predetermined shape by using a molding method such as injection molding or extrusion molding, so that resin foam a can be obtained.

Here, the crosslinking agent E crosslinks one molecule of the low-density polyethylene A and one ethylene-vinyl acetate copolymer B through a crosslinking reaction and connects them together when heated and foamed. Crosslinker E is made from dicumyl peroxide DCP and the like. Likewise, the blowing agent D forms air bubbles 3 in the resin foam when heated and foamed, and the blowing agent D is made of azodicarbonamide AC and the like.

The performance of the resin foam a (embodiment) will be described below using a comparative example.

(1) The main materials used in the embodiment and comparative samples include:

Low-density polyethylene A: low-density polyethylene LDPE produced by Shanghai Petrochemical Co., Ltd.

Ethylene-vinyl acetate copolymer B: Ethylene-vinyl acetate copolymer EVA produced by Beijing Yanhua Newest High-Tech Co., Ltd.

Filler C: calcium carbonate CaCO ₃ produced by Zhejiang Linhua Industrial Co., Ltd.

Foaming agent D: azodicarbonamide AC produced by Zhejiang Haihong Co., Ltd.

Cross-linking agent E: from Shanghai Petrochemical Co., Ltd.

The composition of resin composition in embodiment and comparative sample is as listed in table 1 (each value in table 1 represents a kind of mass parts, and the value of filler C, blowing agent D, crosslinking agent E represents when low density The mass parts when the total mass of polyethylene A and ethylene-vinyl acetate copolymer B is 100 parts by mass. Similarly, although they are not listed in Samples 1 to 3 and Comparative Embodiments 1 and 2 in Table 1 , relative to 100 parts by mass of the total mass of the low-density polyethylene A and the ethylene-vinyl acetate copolymer B, 1.8 parts by mass of antimony oxide (Sd ₂ O ₃ ) needs to be added.

For the measurement of the properties of the resin foam a, compressive residual strain rate and tensile strength were selected. Table 2 shows the results of measurement of the above-mentioned properties for the embodiment and comparative samples. Each property is a measured value obtained by the following evaluation method.

Compression residual deformation rate:

Test piece 50mmx50mmx15mm (d0=15mm)

The test temperature is 15±1℃

Compression rate 53% (thickness before compression is 15mm, thickness after compression is 7mm)

Compression time is 3 hours

Compression residual deformation rate (%) = (d0-dr)/d0X100

d0: Thickness before compression (mm); dr: Thickness after compression load is removed (mm)

tensile strength

JIS K6251 is based on "Vulcanized Rubber and Thermoplastic Rubber - How to Determine Tensile Strength"

【Table 2】

performance Implementation Mode 1 Implementation mode 2 Implementation Mode 3 Comparative sample 1 Comparative sample 2 Compression residual deformation rate (%) 33 40 53 20 53 Tensile strength (MPa) 0.67 0.38 0.30 1.40 0.19

As shown in Table 2, in Embodiments 1 to 3 and Comparative Sample 2, the compression residual deformation characteristics are higher than those of Comparative Sample 1 (even if the compressive load is removed, it does not return to the original thickness), and Comparative Sample 1 has a lower value of 20% (remove the compressive load and return to the original thickness).

On the other hand, as for the resin material, like Embodiments 1 to 3, Comparative Sample 2 used a resin composition not containing an ethylene-vinyl acetate copolymer, and had a high compression residual deformation rate. But, the tensile strength of comparative sample 2 is 0.19MPa, is low with respect to embodiment 1～3, can not be used as insole or the like in practice (for example, if used for insole, tensile strength needs to be 0.20MPa or higher ).

However, the compression residual deformation of the resin foam formed by increasing the mass ratio of the low-density polyethylene A to the ethylene-vinyl acetate copolymer B increases for the following reason. Increasing the mass ratio of the low-density polyethylene A will increase the expansion rate of the foam, so more bubbles 3 will be formed in the resin base 1 .

Also, a large number of formed air bubbles 3 are squeezed due to external force and plastic deformation, and the formed shape can be maintained. In addition, in order to control the decline of the tensile strength of the formed resin foam and ensure the tensile strength in applications, such as the application in insoles, the mass ratio between low density polyethylene A and ethylene-vinyl acetate copolymer B should be The upper limit is set at A/B) = 95/5. The lower limit of the mass ratio between the low-density polyethylene A and the ethylene-vinyl acetate copolymer B is set to A/B=90/10, because if the mass ratio is lower than this value, the value of the extrusion residual deformation ratio will decrease, The shape-retaining ability deformed by external force is impaired.

Next, the molding method of the shoe sole in the utility model will be described in an embodiment with reference to FIGS. 2 to 7( a ) and 7 ( b ).

In FIGS. 2-4, the shoe model M is provided with an insole 20 in the outer sole 14. As shown in FIG. The insole 20 comprises: a middle cushion layer 11 made of resin foam a; an outer cushion layer 12 made in order to enclose the periphery of the middle cushion layer 11 (for example, in order to enclose the middle cushion layer 11 with a frame Manufactured in a manner), which is harder than the middle liner layer 11; and a cover layer covering the outer surface of the outer liner layer 12 and the middle liner layer 11. Reference numeral 15 designates a shell covering, and the shell covering 15 is present only when the shoe model M is a sandal.

The outer cushion layer 12 can prevent excessive deformation added to the middle cushion layer caused by external force, and is further used to maintain the shape of the insole 20 . The outer cushion layer 12 is made of a substance such as ethylene-vinyl acetate copolymer foam, which is harder than the intermediate cushion layer 11 formed of resin foam a.

The decorative layer 13 is made of a material such as an outer layer to improve the appearance of the shoe M. In addition, the decorative layer 13 is preferably made of elastic material, so that it can deform together with the intermediate cushion layer 11 which is next to the covering layer.

Outer sole 14 has shock-absorbing effect, like this, when shoe sample M touches the ground, because the vibration that rough and uneven ground produces can not directly pass on the pin. The outer sole 14 is made of polyurethane, ethylene-vinyl acetate copolymer, synthetic rubber, and the like.

When the M shoe is put on, the outer shell cover 15 rests against the instep and fixes the foot on the M shoe. Shell coverings are made of polyurethane, polyvinyl chloride, leather, and the like.

The use of shoes with insoles is described below.

As shown in Figures 3-6a and 7a, when the shoe sample M is not in use, since the external force has not been applied to the insole 20, the surface that fits the foot still maintains a substantially flat shape.

As shown in Fig. 5a, when the shoe sample is used for the first time, the sole 30 of the foot is close to the covering layer 13 of the insole 20 for the first time, and the insole 20 is deformed by the external force (body weight) acting on the sole of the foot. At this time, since the shape of the sole of the foot in contact with the upper surface of the insole 20 is uneven, the amount of sinking varies for each part and deforms according to the shape of the sole of the foot. Not only does this amount of deformation vary in parts such as the toe, arch, and heel, but it also varies greatly from person to person (due to different heel shapes).

Since the middle liner layer 11 in the insole 20 is composed of resin foam and has high moldability, as shown in Figures 5b, 6b and 7b, even after the shoe is taken off and the external force is removed, the upper surface of the insole 20 Still maintain the shape of the heel. Thus, in a relatively short period of time (eg, approximately 3 hours), a shoe sample can be used to mold an individual heel shape onto the surface of the insole. In this way, it is possible to save time and effort to manufacture shoes suitable for each person's sole shape.

Next, an embodiment of a plantar shape shaping method for a cup-shaped insole is described with reference to FIGS. 8a and 8b:

In the above-mentioned embodiments, an example of a shoe model pre-equipped with the insole 20 and the outsole 14 has been given. Also as shown in Figure 8a, the insole can be made into a single cup-shaped insole N (removable insole).

The cup-shaped insole N includes a middle cushion layer 11 made of resin foam a, an outer cushion layer 12 made to wrap around the outer periphery of the middle cushion layer 11, and its material is harder than that of the middle cushion layer 11. and a covering layer 16 "(referring to Fig. 8 (b)) that covers the whole outer liner layer 12 and middle liner layer 11. Therefore, since the cup-shaped insole N can be placed on the insole of various finished shoes, This makes it possible to create individual foot sole shapes on the surface of the cup insole in a short time using a shoe sample with the cup insole placed in. This saves time and effort in obtaining a shoe that fits the sole shape of each individual's foot. The covering layer 16 ″ is made of a material similar to that used for the covering layer 13 .

Next, another embodiment of the shoe-like sole shape forming method of the present invention will be described with reference to FIGS. 9 to 12a and 12b. The reference letter M' designates a shoe according to the invention, which comprises an outsole 14' and an insole 20' carried thereon. Bond with glue between shoe-pad 20 ' and outsole 14 '. Also, the shoe sample M has a shell cover 15' or a heel 19, as required.

As shown in Fig. 9, the insole 20' comprises a plate-shaped middle cushion layer 11', a plate-like support layer 16 which is located below the middle cushion layer 11' and has the same plan view shape as the middle cushion layer 11'. Adhesive bonding is used between the bonding surfaces of the middle pad layer 11' and the support layer 16.

The middle pad layer 11' plastically deforms along with its uneven shape due to the weight acting on the sole, and forms the uneven shape of the sole on its upper surface. The intermediate cushion layer 11' is made of, for example, plastic resin foam. More specifically, the resin foam is composed of a foamed composition containing low-density polyethylene A, ethylene-vinyl acetate copolymer B, filler C, blowing agent D and cross-linking agent E, low-density polyethylene The mass ratio between ethylene A and ethylene-vinyl acetate copolymer B is A)/B=95/5˜90/10.

Use resin foam a, shoe pattern M ' can give people a sense of comfort, like this, the mass ratio between the total mass of low-density polyethylene A and ethylene-vinyl acetate copolymer B and filler C is preferably set as (A +B)/C=70/30～80/20.

The support layer 16 provides support for the intermediate backing layer 11'. When shoe sample M' is used, in order to prevent deformation in the near horizontal direction (longitudinal and width directions of the insole 20') due to friction between the sole of the foot and the insole 20', the support layer uses 11' harder material. For example, it will use resin plates such as ethylene-vinyl acetate copolymer, polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polycarbonate, carbon, and the like, and the above-mentioned materials will be tested. Foamed resin foam sheets, rubber sheets such as natural rubber, styrene rubber, polyurethane rubber and the like, metal sheets such as aluminium, titanium and the like, or made of, for example, cardboard products, compressed paper and the like Cardboard etc. as material.

The bonding surface between the intermediate pad layer 11' and the support layer 16 is bonded with glue. The bonding range may include the entire above-mentioned bonding surface, or a part of the bonding surface, such as the outer ring of the bonding surface between the middle cushion layer 11' and the supporting layer 16.

Decorative layers and the like use the cover layer 13' to improve the appearance of the shoe pattern M'. In addition, the covering layer 13' is preferably made of a plastic material so that it can be plastically deformed simultaneously with the intermediate cushion layer 11' being attached to the covering layer 13'.

Outsole 14 ' has shock-absorbing effect, like this, when shoe sample M ' touches the ground, because the shock that rough and uneven ground produces can not directly pass on pin. The outsole 14' is made of polyurethane, ethylene-vinyl acetate copolymer, synthetic rubber, and the like.

Next, the production of the basic part insole 20' of the shoe model M' will be explained. First, the support layer 16 and the intermediate backing layer 11' are molded into the same plan view shape by means of a supporting ply, for example, foamed ethylene-vinyl acetate (EVA), and the intermediate backing ply is made of the above-mentioned resin foam a composition.

The support layer 16 and the intermediate pad layer 11' are laminated to each other, and the bonding surfaces between them are bonded with glue. The insole 20' is constructed by adhering the cover layer 13 to the upper surface 11' of the middle cushion layer.

During the construction of the insole 20', after pre-adhesive bonding and lamination of the above-mentioned support plies and intermediate cushion plies, the insole 20' can be formed by molding the laminated object and placing the cover layer 13' It is formed by sticking on the upper surface of the intermediate cushion layer 11'. In other embodiments, the insole 20' may be formed by molding an already laminated object after pre-gluing and laminating the support ply, middle sock ply and cover ply. . Likewise, the molding method of the intermediate backing layer 11' and the support layer 16 may utilize any of the previously known methods, for example, the support layer 16 and the intermediate backing layer 11' may be laminated and molded simultaneously by stamping.

Next, the application of the shoe sample M' conforming to the utility model will be described. Figure 10a shows an unused shoe sample M' with a substantially flat upper surface of the insole 20'. But as shown in Figure 10b, after a short period of use, due to the weight acting on the soles of the feet, the upper surface of the middle cushion layer 11' will undergo plastic deformation with different sole shapes. The shape of the sole of the foot is molded onto the insole 20'.

In the structures disclosed in the above embodiments, the bonding surfaces between the intermediate pad layer 11' and the support layer 16 are glued and fixed to each other. Anyway, its structure can be shown in Figure 11. The middle pad layer 11' and the supporting layer 16 are attached to each other, and the upper surface of the middle pad layer 11' is covered by the cover layer 13'. Also, the edge of the cover layer 13' is folded inward to the lower surface of the support layer 16, and the bonding surface 16a' between the flanging 13a' of the cover layer 13' and the support layer 16 is bonded with glue.

Likewise, as shown in FIG. 12a, corresponding to the junction b3 between the heel b2 and the arc b1 between the middle cushion layer 11' and the support layer 16, there is a barrier layer 17 protruding towards the cover layer 13', To block the movement of the heel b2. In another embodiment, as shown in FIG. 12b, there is a barrier layer 18 towards the cover layer 13 corresponding to the junction b3 between the heel b2 and the arch b1 between the outsole 14' and the support layer 16. ' raised to block the movement of the heel b2. Owing to having had barrier layer 17 and 18, sole shape just can be adapted to the sole shape of each person formed on the upper surface of insole 20'. Figures 12a and 12b show an unused shoe sample M'. For the sake of convenience, a dotted double-dotted line is drawn in the figure, and the corresponding relationship between the soles of the feet and the insole 20' is provided at the same time.

Next, with reference to Figs. 13-16a and 16b, another embodiment will be used to describe the method for forming the sole shape of the cup-shaped insole in the utility model. Reference letter N' designates a cup-shaped insole according to the invention. As shown in Fig. 13, the cup-shaped insole N' comprises a plate-shaped middle layer 52, a plate-shaped support layer 51 which is the same shape as the middle liner layer 52 in plan view and is located below the middle liner layer plate 52, and at least one The covering layer 53 which shall cover the upper surface of the intermediate backing layer. The bonding surface between the intermediate pad layer 52 and the supporting layer 51 is bonded with glue. The cup insole is used by being placed on the insole of the finished shoe m.

Each material used for the supporting layer 51, the intermediate backing layer 52 and the covering layer 53 is the same as that used for the supporting layer 16, the middle backing layer 11' and the covering layer 13' in the above embodiment. The structure and production method of the cup-shaped insole N' are the same as the insole 20' in the above-mentioned embodiment, so no more detailed description here.

The use of the cup-shaped insole N' according to the invention will be described below. The state of an unused cup-shaped insole N' placed in a finished shoe m is shown in Fig. 14a. The upper surface of the cup-shaped insole N' is generally flat, but as shown in FIG. Plastic deformation is produced so that each person's various foot shapes are formed on the cup-shaped insole N'.

The above description describes a structure in which the mating surfaces between the intermediate backing layer 52 and the support layer 51 are glued and fixed to each other. However, the structure can also be as shown in Figure 15 below. The middle pad layer 52 and the supporting layer 51 are attached to each other, and the upper surface of the middle pad layer 52 is covered by the covering layer 53 . Also, the edge of the cover layer 53' is folded inward to the lower surface of the support layer 51, and the bonding surface 51a between the flanging 53a of the cover layer 53' and the support layer 51 is bonded with glue.

Similarly, as shown in Figure 16a, at the corresponding position between the heel b2 and the junction b3 between the arch b1 between the middle cushion layer 52 and the support layer 51, there is a barrier layer 54 protruding toward the cover layer 53 to block Movement of the heel b2. Alternatively, as shown in FIG. 16b, corresponding to the junction b3 between the heel b2 and the arch b1 below the support layer 51, a blocking layer 55 protrudes toward the covering layer 53 to block the movement of the heel b2. Thanks to the barrier layers 54 and 55, the shape of the sole of the foot can be adapted to the shape of the sole of each person formed on the upper surface of the cup-shaped insole N'. Figures 16a and 16(b) show an unused shoe sample N'. For convenience, a dotted double-dotted line is drawn in the figure, and the corresponding relationship between the sole of the foot and the cup-shaped insole N' is given.
