Abstract

PURPOSE:To increase the efficiency of the work underumentioned, to improve the quality of its product and to diversify its design when trimmings for preventing sand, water and the like are fixed on a skin. CONSTITUTION:A lining 11 is manufactured by a method wherein trimmings such as a tongue 14 for preventing sand and a pad 15 around an opening for putting on a shoe are fixed to an upper lining 12 in a sewing process, and the lining 11 formed by such the method is fixed to a skin formed by slush molding. In this way, the mounting members such as the tongue 14 and so on are respectively located at a definite position on the skin, and are easily joined to the skin, and thus on a production line ranging from the slush molding till the complete product of the shoe, it is made unnecessary to provide these mounting members. Part of an upper member is also fixed on the lining. In this way, the design of the shoe is diversified, which is different from a usual method.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining integrated with a covering material for improving shoe manufacturing efficiency, diversifying designs, etc., a method for manufacturing a slush molded shoe using the same, and a slush molded shoe.

[0002]

2. Description of the Related Art In slush molding, first, a paste such as PVC is poured into a shoe mold, and the mold is heated for a short time to gel the paste in a portion in contact with the mold. Next, after discharging the extra gel which is not gelled, it is further heated to completely solidify the gelled portion to mold the outer skin. Then, after releasing the solidified outer skin from the mold,
The excess portion on the side of the crotch is cut, and a sock-shaped lining prepared separately is attached to the outer skin by sticking or the like. In such a slush-molded shoe, the sole and the cover are continuously formed integrally. Therefore, as in the case of hand-sewn / tensioned shoes or injection-molded shoes, the sole and the cover are sewn together when it rains or snows. There is no inconvenience that water permeates into the shoe from the parts. Also,
The slush-molded shoe has the advantage that the surface of hand-sewn / tensioned shoes, the sewing thread, etc. can be precisely expressed on the molding surface.

However, since the mold used for slush molding is cylindrical, the overall shape of the outer skin must be monotonous. For example, the outer skin is used for the shoe pad, sand removal, and water removal. It is impossible or extremely difficult to form it integrally with the cover as a part of. For this reason, slush-molded shoes have hitherto been mainly applied to boot-type shoes mainly for the purpose of preventing cold and waterproof, and most of them have a relatively simple structure. However, recently, various techniques such as outer surface treatment, cutting, and sewing of the outer skin have progressed, and therefore, attempts have been made to use the slush-molded shoe as a fashionable type or sporty type shoe. In such a type of shoe, the outer skin is made of a similar material or a different material having a different texture, color, etc., which is manufactured separately from the outer skin, and a wearing member for sanding, draining, etc. Can also be attached according to the design, application, etc.

FIGS. 7A to 7C show a conventional example of a method for manufacturing a slush-molded shoe to which such a wearing member (in this case, sand removing and a shoe mouth pad) is attached. First, as shown in FIG. 7 (A), a sock-shaped lining 1 and an outer skin 2 formed by slush molding.
And are prepared. As shown in the upper diagram of FIG. 1 (A), the lining 1 includes an upper lining material 3 (at the bottom, which is sewn with, for example, a bore cloth, a tricot cloth, or a laminated cloth.
Bore, felt, canvas, leather board, synthetic leather, natural leather, insole cloth 9 made of general fiber cloth etc.) and insole 4 made of leather board etc. are joined by stitching, fusion, adhesion, etc. Is configured. Next, the lining 1 is suspended in an outer skin 2 formed by cutting the upper portion into an appropriate shape as shown in the lower diagram of FIG. 7 (A) and attached by sticking or the like. In the conventional slush-molded shoe, the outer skin 2 is cut so that the height of the mouth opening becomes lower as shown in the lower diagram of FIG. 7 (A), and the upper end of the mouth opening as shown in FIG. 7 (B). It is designed so that the mouth opening pad 5 is largely exposed. This mouthpiece pad 5 is obtained by attaching the lining 1 to the outer skin 2 and then, as shown in FIG.
As shown in FIG. 7, the shoe is sewn from the inside of the shoe to the mouth opening portion of the outer skin 2 (sewn portion is indicated by 7).

Further, as shown in FIG. 7B, a separately prepared sand removing member 6 is arranged in the opening formed in the outer portion of the outer skin 2, and the sand removing member 6 is removed. As shown in FIG. 7C, the outer skin 2 positioned on the outer skin 2.
Are sewn on (the sewn portion is indicated by 8). In addition to the shoe pad 5, the sand remover 6, and other wear members such as water remover, the outer skin is also attached as a member different from the lining 1 as described above.

[0006]

However, in the slush molding, as described above, the lining 1 is formed on the outer skin 2.
After attaching the, the wearing member (the mouth opening pad 5 and the sand removing member 6) as a separate member is attached to a predetermined portion, so it is necessary to provide a large number of the wearing member on the shoe production line,
Parts management becomes troublesome. In addition, it takes a lot of time to set and position these wearing members on the outer skin 2, or to temporarily fix or sew them, and the process of attaching the wearing members slows down the flow of the manufacturing line, resulting in a manufacturing efficiency. There is a problem that

Further, when the wearing member is improperly set or is mispositioned, a problem such as meandering or disengagement of the sewing thread, misalignment or twisting of the member, or wrinkling due to sewing mistakes occurs, resulting in slash. There is a problem that the quality of the molded shoe itself is deteriorated.

Further, since the material used as the outer skin is limited to PVC or the like, there is a strong tendency that the color and texture are monotonous. For this reason, although the design is changed by coloring the surface of the outer skin, there is a limit in diversifying the design of the shoe itself by coloring.

The present invention has been made in consideration of the above circumstances, and improves the work efficiency when mounting a wear member such as a shoe mouth pad, sand remover, and water remover on an outer skin, and a slush molded shoe. The lining and the lining of the covering material, which improves the quality, and dramatically improves the freedom of design of the slush molded shoe by changing the color and texture of the covering material by a method different from the conventional one. An object of the present invention is to provide a method for manufacturing a slush-molded shoe used and a slush-molded shoe.

[0010]

The lining integrated with the covering material of the present invention is a lining attached to an outer skin formed by slush molding, and is referred to as an upper lining material (hereinafter simply referred to as "lining material"). ), A part of the covering material to be joined to the covering skin is attached to the predetermined portion. Further, a part of the covering material includes a part of the covering body or is a wearing member of the covering material. Furthermore, in the method for manufacturing a slush molded shoe of the present invention, after the lining integrated with the covering material is attached to the covering skin, a part of the covering material attached to the lining material is joined to a predetermined portion of the covering skin. It is characterized by doing. In addition, the slush-molded shoe of the present invention is characterized in that the main body of the shoe cover is composed of two or more members, and at least the shoe sole and the portion of the shoe cover continuous with the shoe sole are formed by slush molding.

In the present invention, the "wearing member" means a shoe pad, sand remover, water remover, rubber band, fastener, etc., which can be generally attached to the outer skin body by adhesion, sewing, fusion or the like. The covering material and the covering material that is attached to the inside of the covering such as the counter, toecap, and insole. The "covering body" is the part of the covering material other than the above "wearing member" (that is, the covering material). Of these, the part that was conventionally formed by slush molding). Further, “joining” refers to various joining means such as sewing, adhesion, and fusion.

[0012]

According to the present invention, the lining is manufactured by attaching a part of the covering material (a part of the shoe pad, sand removal, water removal, etc. and a part of the covering body) to the lining material at the sewing stage. It In addition, when the lining is suspended and attached to the outer skin, a part of the covering material attached to the lining material is set at a predetermined portion of the outer skin. As a result, in the subsequent step, joining of the covering material to the outer skin by stitching or the like is easily performed. When the lining is attached to the skin, for example, it may be attached in a free state or attached.

When a part of the covering material is a wearing member such as a shoe mouth pad, sand remover, rubber, a fastener, a counter, a toecap, an insole, etc., the wearing member is subjected to slush molding to commercialization of shoes. Since it is not necessary to provide the line as an independent component, the number of components to be provided on the line is reduced. This eliminates the need to manage the wearing members on the line. Further, the step of attaching the wearing member to the outer skin is simplified, and the care and labor required for setting and positioning the wearing member is reduced. This further improves work efficiency.

When a part of the covering material includes a part of the covering body, the same material as the covering skin can be used as the material of the covering material, and the covering skin is a color,
Materials with different textures (different materials) can also be used. This makes it possible to diversify the design of the body to be covered by a method different from the conventional method.

In addition, in the slush-molded shoe of the present invention in which at least the shoe sole and the covering portion continuous with the shoe sole are formed by slush molding, regardless of whether or not the shoe is manufactured by the above-described manufacturing method. Can cope with diversification of designs. Further, the same waterproofness as that of the conventional slush molded shoes is ensured.

[0028]

As described above, according to the present invention, the following effects can be obtained. (1) By preliminarily mounting the wearing member such as the shoe opening pad and sand remover on the lining material, it is not necessary to provide an independent wearing member in the production line from slush molding to shoe completion. As a result, the number of parts to be provided in the line is reduced, and the complexity of handling can be eliminated and the parts management can be facilitated.

(2) At the same time when the lining is attached to the outer skin, a part of the wearing member or the main body of the armor attached to the lining material is set at a predetermined portion of the outer skin. Therefore, in a step following the step of attaching the lining to the outer skin (which does not necessarily have to be a step immediately after), it is possible to easily position a part of the wearing member or the main body of the covering and join the outer skin to the outer skin. Therefore, the manufacturing process can be simplified and the work efficiency can be improved. Also, along with this, the sewing thread meanders and comes off,
Alternatively, it is possible to prevent the displacement, twisting, and wrinkling of the members during sewing, and to improve the quality of the slush molded shoe.

(3) It is also possible to form a part of the wearing member such as the shoe mouth pad, sand remover, etc. or the main body of the covering by the same material as the covering skin, and these are different from the covering skin in texture, color and the like. Since it can be made of a material, it is possible to diversify the design and functions of the slush molded shoe. Further, in particular, in a slush molded shoe in which the lining of the cover material is a part of the cover body, it is possible to further diversify the design of the cover body, which tends to be monotonous in the past, and at the same time, By changing only a part, it is possible to easily manufacture shoes having different waterproof properties and cold weather properties even if the outer skin is molded from the same mold.
