Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a shoe in which the heel of a shoe is formed and held in a desired shape by using a loincloth made by integrally molding the outer surface of the heel, without the need for seams at the back of the heel. The present invention relates to a shoe with a cover and a manufacturing method thereof.

Traditionally, shoe covers have been divided into a pressed surface that covers from the toe to the instep, and inner and outer loincloths, or inner and outer coverlets, and most of the fabrics are joined by sewing. There is. Looking at the outer surface of the heel part of the shoe cover, first the inner and outer loin cloths or the inner and dropper covers are sewn together, and then the heel cover pieces are covered over them to reinforce the sewn parts. In addition, a heel decoration piece is sewn to the upper part of the heel, and it can be seen that the sewing process is particularly concentrated on the heel part. This means that the heel part is exposed to a wide variety of adverse external conditions, so it must be reinforced to prevent damage from the seamed part, which is not only uneconomical as it requires unnecessary time and effort. First, the shoes are subject to heavy use by the wearer, who steps on the heels of the shoes and puts them on and takes them off, and damage such as thread breaks in the seams still occurs. In addition, when sewing the heel part together, it is desirable to form a curved part that fits the shape of the heel, and sewing requires skill. Furthermore, each part is overlapped while maintaining the shape of the curved part. Sewing them together requires great care and a lot of effort.

The present invention solves the above-mentioned problems, and as described in the claims, the present invention has a sewn part such as a heel decoration piece that covers a high-frequency welding machine to form a part of a desired shape and a decorative seam pattern on the outer surface. There is no need to sew the inner and outer loincloths or the inner and outer loincloths together, and there is no need to sew each part on top of it. Since there is no need for overlapping stitching, it is possible to eliminate the extremely difficult sewing work required to make the heel part shape after sewing into a curved part that matches the shape of the heel, which is required in conventional products. ) and the heel lining fabric (2) by simply applying heat and pressure to adhere the heel counter [31] using any method, it is possible to form and maintain a heel portion in a desired shape extremely easily. It is possible to achieve excellent effects such as:

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1 and FIG.
After cutting into a single sheet with both inner and outer loincloths, a high-frequency welding machine is used to create heel decorations, decorative seam patterns, etc. on the surface of the sheet.If necessary, The heel abutment piece and the heel abutment piece are formed by welding to the outer surface of the heel portion of the previous sheet using a high frequency welder. The heel lining cloth +21 is made of commonly used cloth, leather 1 synthetic leather, vinyl leather, etc.
) is cut into an appropriate shape. The heel counter 131 is made by cutting a leather board, a thermoplastic resin sheet, a thermosetting resin sheet, etc. into an appropriate shape, and may also be formed to correspond to the curvature of the heel, and has adhesive on both sides. For example, apply hot melt adhesive or the like.

The above-mentioned loin cloth 11) and heel lining cloth 12) are overlapped with the inside sides facing each other, and the upper edges corresponding to the shoe opening are sewn together, and the heel lining cloth (2) is turned over so that it is located inside the heel cloth pile. After sewing or pasting, the tip height (4) etc. are sewn to the tip part to form the heel cover (5), and the heel cloth 11) and heel lining cloth 12+ of the heel cover (5) are sewn. Attach the heel counter (3) between them and use a counter dresser or the like to press and adhere the heel counter (3) to the waist cloth 11) and the heel lining cloth +21, Fake cover (5
) is formed and maintained as a curved portion corresponding to the heel, and then an insole, outsole, etc. is attached to obtain the desired shoe. Since the loin cloth 11) is made of thermoplastic resin leather, it easily conforms to the shape of the heel counter 13) etc. by heat setting, etc., and is formed and held in that shape, so that the desired heel shape can be maintained.

The shoe cover 15) is also used for shoes whose soles are integrally formed by cast molding or injection molding, as a shoe cover whose lower periphery is sewn with an insole cloth.

As described above, the present invention uses a single sheet of loincloth and has no seams on the outer surface of the heel, so even under extremely harsh wearing conditions, damage such as thread breakage does not occur, and unlike conventional By using this method, the heel counter can be easily bonded, and at the same time, the heel portion of the heel can be formed and maintained in a desired shape, which has excellent effects.

Claims (1)

[Scope of Claims] / A single-sheet thermoplastic resin leather loin cloth in which parts of a desired shape and decorative seam patterns, etc. are integrally displayed on the outer surface of the thermoplastic resin leather, and there is no joint seam at the back of the heel. and a heel lining cloth located inside the heel portion and sewn to the loin cloth at the upper edge of the shoe opening.
Shoes having a heel counter formed by a heel counter that is clamped between the heel lining fabric of the loincloth and a front heel that is sewn to both end edges of the loincloth. 2. After attaching the heel consisting of the loin cloth, heel lining cloth, heel lining cloth, and heel counter to the shoe last, the heel counter is made to appear as one piece by attaching the sole, and the heel counter is glued between the loin cloth and heel lining cloth. A method for manufacturing shoes having a heel, characterized in that the heel part of the heel is adapted to the shape of the heel counter, and a curved part of the heel of the heel is formed and held by the shape-retaining force of the heel counter.
