Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shoe in which an upper shoe part and a lower shoe part made of different materials are temporarily fixed with double-sided adhesive tape, positioned and sewn together.

[Conventional technology]

In the past, the main body of a shoe was generally made of a cylindrical upper shoe part and a lower shoe part that fit around the foot, but recently, shoe bodies have been made with the aim of making shoes more luxurious or having a design effect. As a result, a type in which the upper shoe part and the lower shoe part are made of different materials and sewn together has come to be widely adopted.

Conventional shoes of this type have a cylindrical upper shoe made of synthetic leather, for example, and a lower shoe made of synthetic resin such as vinyl chloride resin using the slush molding method. It is known that they are overlapped and sewn together.

Then, a double-sided adhesive tape is pasted along the curved surface of the opening end to the joint part of the lower shoe part, that is, to the periphery of the open end of the upper shoe part, and the double-sided adhesive tape connects the upper shoe part and Temporary fixing of the lower shoe part,
Positioning is being done.

The above-mentioned positioning method includes applying an adhesive, but because the adhesive protrudes from the joint and reduces product quality, double-sided adhesive tape is mainly used.

[Problem that the invention attempts to solve]

However, in such conventional shoes, the core material of the double-sided adhesive tape for positioning is made of a non-woven fabric with low elasticity, such as cellulose (Japanese paper), rayon, nylon, or polyester, or a woven fabric with low elasticity. Therefore, when pasted on the periphery of the opening end of the lower shoe, depending on the curved surface of the opening end, there will be a difference in the amount of expansion and contraction on the left and right ends of the tape in the pasting direction, so the tape on the stretch side If the end is cut or the tape end on the shrink side is doubled,
It was often triple-folded.

Therefore, this repair not only reduces the efficiency of positioning work, but also causes unnatural unevenness or wrinkles on the outer surface of the joint, which is important for design, after stitching, impairing the appearance and deteriorating the quality of the product. There was a problem.

The present invention was developed in response to the problems of the conventional technology, and by improving the core material of the double-sided adhesive tape for positioning, it streamlines the positioning work, improves the design appearance, and improves product quality. The aim is to provide shoes that can

[Means for solving problems]

The present invention provides a shoe in which a lower open end of a cylindrical upper shoe part is sewn to an open end of a lower shoe part, in which a core material having elasticity is provided around the open end of the lower shoe part. To provide a shoe in which a tape-like double-sided adhesive member is attached, and an upper shoe part and a lower shoe part are positioned and sewn together using the double-sided adhesive member.

[Effect]

In the present invention, a tape-shaped double-sided adhesive member made of an elastic core material is attached to the periphery of the opening end of the lower shoe part, and the upper shoe part and the lower shoe part are fixed to each other by the adhesive member. sutured.

In addition, since the core material of the double-sided adhesive member has elasticity, it adapts well to the curved surface of the periphery of the opening end to which it is attached, and does not cause unevenness, wrinkles, etc., or breakage. There is no need for repairs, the efficiency of positioning work is improved, and the design appearance of the outer surface of the joint is not impaired, so a high-quality product can be obtained.

〔Example〕

The present invention will be described below with reference to the drawings, but the present invention is not limited to the embodiments shown below.

In describing the embodiments of the present invention, we will take as an example a boot in which the upper shoe part is made of, for example, synthetic leather, and the lower shoe part is made of, for example, vinyl chloride resin, and is molded by a slush molding method.

1 and 2 are diagrams showing one embodiment of the present invention.

First, the configuration will be explained.

In FIG. 1, reference numeral 1 denotes the upper shoe part of the boot 2, and as described above, the upper shoe part 1 is made of synthetic leather, for example, and is formed into a cylindrical shape.

Further, reference numeral 3 designates a foot-shaped lower shoe part of the boot 2, which is made of, for example, vinyl chloride resin and is molded by the slush molding method. An open end 3a is formed corresponding to the shape of the lower open end 1a.

Then, as shown in FIG. 2, the lower open end 1a of the upper shoe part 1 is overlapped with the open end 3a of the lower shoe part 3 and sewn together by a sewing machine such as a sewing machine to form the boot 2. Ru.

On the other hand, in FIG. 1, reference numeral 4 indicates the lower shoe portion 3
It is a tape-shaped double-sided adhesive member stuck to the periphery of the opening end 3a along the curved surface of the opening end 3a,
In order for the double-sided adhesive member 4 to adhere well to the curved surface, the tape-shaped core material 4a of the double-sided adhesive member 4 is made of, for example, knitted fabric such as tricot, knitted fabric, or foamed material such as polyurethane or vinyl chloride resin. or made of stretchable material such as cheesecloth. The material of this core material 4a is not limited to the above-mentioned material as long as it is stretchable.

By means of this double-sided adhesive member 4, the upper shoe part 1 and the upper shoe part 3 are temporarily fixed and positioned with respect to each other so that they will not shift during sewing.

Note that, as a matter of course, the inner surfaces of both the upper shoe part 1 and the lower shoe part 3 are provided with lining cloth.

These lining fabrics are integrally formed into a stocking shape, and the upper cylindrical part is sewn in advance to the inner surface of the upper shoe part 1 made of synthetic leather, and the upper last part is molded using a last mold. The lower shoe part 3
Since the upper shoe part 1 and the lower shoe part 3 are sewn together, there is no seam in the lining fabric, and consideration has been given so that the boot 2 does not become uncomfortable to wear. .

In addition, these lining fabrics are sequentially sewn into a cylindrical shape, with the lining fabric of the lower shoe part 3 part, the lining fabric of the upper shoe part 1 part, and the synthetic leather that will be the front side of the upper shoe part 3 on the back side, After fitting this into a last mold and fitting it into the lower shoe part 3, the synthetic leather is turned over to form the upper shoe part 1, and the lower opening end 1a of the upper shoe part 1 and the upper part of the lower shoe part 3 are formed. The opening end 3a of the shoe portion may be sewn together.

Next, the effect will be explained.

In FIG. 1, a tape-shaped double-sided adhesive member 4 is attached to the periphery of the open end 3a of the lower shoe portion 3 along the curved surface of the open end 3a.

Then, the opening end 1a of the lower shoe part 1 of the upper shoe part 1 is overlapped with the opening end 3a, and the upper shoe part 1 and the lower shoe part 3 are temporarily fixed and positioned with respect to each other by the double-sided adhesive member 4, and further, a sewing machine, etc. The boots 2 are sewn together by a sewing machine as shown in FIG. 2 to form the boot 2. At this time, since the core material 4a of the double-sided adhesive member 4 for positioning is made of a stretchable material as described above, both the left and right ends are expanded and contracted from the curved surface of the opening end 3a toward the pasting direction. Even when the curved surface is curved, the double-sided adhesive member is adhered to the curved surface without cutting the stretched side or folding the contracted side.

This eliminates the need for repair work such as re-attaching when the double-sided adhesive member 4 is cut or folded over, and shortens the working time, thereby improving the efficiency of the positioning work.

Furthermore, the joint surface after suturing, that is, the upper shoe part 1
It is possible to prevent unevenness, wrinkles, etc. from occurring on the outer surface of the open end portion 1a that would impair the design appearance.

As described above, in this embodiment, since the core material 4a of the double-sided adhesive member 4 for temporarily fixing and positioning the upper shoe part 1 and the lower shoe part 3 to each other is made of a stretchable material, the double-sided adhesive member 4 is attached so as to blend well with the curved surface of the peripheral edge of the opening end 3a of the lower shoe portion 3,
No unevenness, wrinkles, etc., or cutting. As a result, the efficiency of positioning is improved, and the quality of the boot 2 can be improved without impairing the aesthetic appearance of the joint.

[Effect of idea]

According to the present invention, the core material of the double-sided adhesive member that positions the upper shoe part and the lower shoe part with respect to each other has elasticity, so that the double-sided adhesive member adapts well to the curved surface of the periphery of the opening end of the lower shoe part. It is possible to prevent unevenness, wrinkles, etc. from occurring and cutting. Therefore, the efficiency of positioning work is improved, and a high quality product can be manufactured without impairing the design appearance of the joint.
