Abstract

(57) [Summary] [Purpose] To obtain a sandal insole that is easy and efficient to manufacture, has a good feel when worn, and has a beautiful appearance. [Constitution] The insole 1 of a sandal is made of ethylene / vinyl acetate copolymer, and is a single horizontal letter-shaped first part joined to the front end on the surface of an insole main body 2 which is integrally molded as a whole. It is composed of a decorative piece 3A and a vertically elongated elliptical second decorative piece 3B joined slightly to the center. Cloths of different colors are used for the first decorative piece 3A and the second decorative piece 3B.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the insole of sandals.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional insole (11) of this kind is covered and adhered to the cardboard core (12) from the upper and peripheral surfaces of the ball paper core (12) to the peripheral edge of the lower surface. It consisted of a synthetic resin skin (13).

In the drawing, (14) is a heel core made of wood or synthetic resin, (15) is a synthetic resin skin covering the outer surface of the heel core (14) and a part of the upper and lower surfaces connected to the outer surface, (16) is a rubber or synthetic resin book sole, and (17) is a band.

[0004]

[Problems to be solved by the device]

 In the conventional insole, it is necessary to cover and adhere the synthetic resin skin from the upper surface and the peripheral surface of the cardboard core to the peripheral edge of the lower surface, which is not only troublesome and inefficient to manufacture, but also when wearing sandals. I couldn't always say that the feel of the soles of the feet was satisfactory.

An object of the present invention is to provide a sandal insole that is easy and efficient to manufacture, and has a beautiful appearance with a good sole feel when worn.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the insole of the sandal according to the present invention is made of ethylene / vinyl acetate copolymer, and the whole of the insole body is integrally molded. The decorative piece is partially joined to one or more places and has a color different from that of the insole body.

[0007] In the above integral molding, it is preferable that the foamed ethylene / vinyl acetate copolymer material is thermocompression-molded into a predetermined shape of the inner bottom body and contains extremely fine bubbles, but it is foamed. It may not exist or may contain relatively large bubbles inside.

Further, the decorative piece is applied to the surface of the foamed ethylene / vinyl acetate copolymer material via a hot melt adhesive and simultaneously welded when the insole body is thermocompression-molded.

The material of the decorative piece is preferably cloth so as to absorb sweat from the sole of the foot, but synthetic leather or ethylene / vinyl acetate copolymer may be used. However, it is not possible to use a material such as vinyl chloride that cannot withstand the heat at the time of thermocompression molding.

The portion of the insole body to which the decorative piece is joined is preferably formed in a concave shape according to the shape and thickness of the decorative piece, but it may be flat.

[0011]

[Action]

 The inner bottom of the sandal according to this invention is made of ethylene / vinyl acetate copolymer, and the whole body is molded integrally. Does not need

Further, the sole of the foot comes into contact with an ethylene / vinyl acetate copolymer molded product which gives a soft feeling.

Furthermore, since the decorative piece having a color different from that of the insole body is partially bonded to one or more arbitrary places on the surface of the insole body, the entire insole is made of ethylene. If it is only formed of a vinyl acetate copolymer, it is limited to one color, but there are multiple colors.

[0014]

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

Example 1 This example is shown in FIGS. 1 and 2, wherein the insole (1) is made of an ethylene / vinyl acetate copolymer, and the surface of the sole is such that the sole of the foot is formed. The insole body (2) integrally formed on the whole, the first decoration piece (3A) in the shape of a horizontal letter joined to the front end on the surface of the insole body (2), and the center It consists of a vertically elongated elliptical second decorative piece (3B) joined slightly to the front. Both decorative pieces (3A) and (3B) have different colors from the insole body (1), and The first decorative piece (3A) and the second decorative piece (3B) are made of cloths of different colors.

The insole body (2) contains fine bubbles obtained by thermocompressing a foamed ethylene / vinyl acetate copolymer as described above. It is joined to the outsole (6) formed of the same material as the above and both ends of the band (5) are caught between the insole (1) and the outsole (6) to form a sandal. Has been.

The outsole may be formed of vinyl chloride, polyurethane or the like.

Example 2 The insole (7) of this example is shown in FIGS. 3 and 4, and is the same as Example 1 except for the following points.

That is, in the first half of the length of the insole body (8), a drip-shaped recess (9) is formed inward of the peripheral edge, and a large number of slanted ridges (in a plan view) are formed inside thereof. 10) is provided, and a cloth decorative piece (3C) having the same shape as the bottom of the recessed portion (9) so as to cover a large number of uneven strips (10) and having a different color from that of the insole body (8). Are joined together.

Since the sandals are the same as those of the conventional example shown in FIG. 5, the same parts are designated by the same reference numerals and the description thereof will be omitted.

[0021]

[Effect of device]

 According to the insole of the sandal of the present invention, it is not necessary to combine the core material and the outer skin as in the conventional case, and therefore the manufacturing can be performed easily and efficiently.

Further, since the sole of the foot is in direct contact with the molded product of ethylene / vinyl acetate copolymer giving a soft feeling, it is comfortable to wear sandals.

Furthermore, since the decorative piece partially bonded to the surface of the insole body can be different in color from the insole body, it is harmonious in relation to the respective colors of the band and the insole body. By choosing a color, you can get a sandal insole with a beautiful appearance.
