Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe manufacturing method.

[0002]

2. Description of the Related Art Heretofore, Japanese Utility Model Publication No. 41-20408 has proposed an insole composed of an insole body having a through hole formed in the stepping portion and a cushion material adapted to be inserted into the guiding hole. ing.

However, this insole is set on the bottom surface of the shoe mold during the shoe assembling process, and the outer peripheral edge of the shoe cover is hung on and bonded to the underside of the shoe so that the insole is transparent. Since the holes are drilled, it is not possible to accurately fit the instep portion of the insole to the bottom of the last during hanging work, and the through hole makes the outer periphery of the instep portion fragile. However, there is a drawback in that the work of suspending the sneakers is hindered because the area around the stepless part of the insole is damaged when suspending the swords, and the finished shoe loses its shape.

[0004]

SUMMARY OF THE INVENTION According to the present invention, by simply devising the insole, the insole can be accurately fitted to the bottom of the last when the bulge is hung so that the lifting work is easy and the cushioning property is improved. It is intended to manufacture excellent shoes.

[0005]

The present invention will be described below with reference to the drawings showing the embodiment. In the present invention, except for the tearable connecting sides 111.111 ..., a cutting line 121 cut in the center side of the step portion is used. Surrounded peeling piece 1
Set the insole body 1 with 2 on the bottom surface of the last 5,
An adhesive is applied to the outer peripheral lower surface 10 of the insole body 1 and dried, and the cover 3 is hung on the last 5, and the lower peripheral upper surface side 31 is attached to the insole body 1.
After adhering to the outer peripheral lower surface 10 of the inner bottom body 1, the peeling piece 12 of the inner bottom body 1 is peeled from the inner bottom body 1 by tearing and cutting the connecting sides 111.111 ... A cutout portion 11 is formed on a side, and a cushion material 2 formed corresponding to the shape of the peeling piece 12 is fitted and set in the cutout portion 11, and the lower peripheral lower surface side 32 of the cover and the lower surface of the insole body 1 are set. The gist of the invention is a method of manufacturing a shoe, which is characterized in that the shoe sole 4 is adhered to the.

In the present invention, the insole body 1 is made of leather, a laser board, a fiber board, etc., and is formed on the central side of the step portion, specifically, the second to third metatarsal bones. A semi-elliptical or trapezoidal cut line 1 having a portion corresponding to the head as a nadir and a portion corresponding to the bottom of the first to fourth metatarsals as a base.
21 is engraved, and the peeling piece 12 is formed by being surrounded by the cut line. In the embodiment, the flank 121 ′ of the peeling piece, the left and right sides 121 ″, 121 ″, the bottom 12
1 ″ ′ is provided with tearable connecting sides 111, 111 ... For connecting and holding the peeling piece 12 to the insole body 1. The connecting sides 111, 111 ...
When the 21 is engraved, the cutting lines 121 can be provided at the same time by engraving and cutting the connecting lines 111, 111 ...

In the embodiment of the present invention, if the upper surface of the insole body 1 is provided with a softer leather, a synthetic resin sheet, or an upholstery 13 made of cloth, the foot contact when worn is further improved. Can be one.

In the embodiment of the present invention, the cushion material 2
Is composed of a latex foam, a urethane foam, and a soft rubber foam, and is formed corresponding to the shape of the peeling piece 12. In the embodiment of the present invention, when the insole body 1 having the upper surface thereof provided with a flexible overlay 13 is used,
This is convenient because it is not necessary to insert a separately prepared insole into a completed shoe and insert it into the shoe. In this case, if the cushion material 2 is made thicker than the insole body 1,
Connection side 111, 111 that can be torn freely after hanging
Is torn to peel off the peeling piece 12, and the cushion material 2 is fitted to the cutout portion 11 formed on the peeling piece 12 portion,
When the shoe sole 4 is bonded to the midsole 1, the thick portion of the cushion material 2 is pushed up by the upper surface of the shoe sole, and the pushing pressure causes the upholstery to swell into the shoe. By supporting the horizontal axis arch portion formed on the central side of the stepping portion on the back side, the comfort can be further improved.

[0009]

OPERATION OF THE INVENTION Insole body 1 prepared as described above
Since the cushioning material 2 and the cushioning material 2 are used as described in the embodiment, the inner sole body 1 is set on the bottom surface of the last 5 by a conventional method in the process of assembling the shoe, and the outer peripheral lower surface 10 of the inner sole body 1 is set. An adhesive agent is applied to and dried, and the cover 3 is hung on the last 5 and the lower peripheral upper surface side 31 is adhered to the outer peripheral lower surface 10 of the insole body 1, and the lower peripheral lower surface side 32 of the cover is buffed if necessary. After that, the connecting sides 111, 111 ... Are torn and cut to peel off the peeling piece 12 from the insole body 1 to form a cutout portion 11 at the center side of the stepping portion of the insole body. 2 is fitted and set. If the double-sided adhesive tape 21 is previously attached to the upper surface of the cushion material 2 before setting, the cushion material 2 is inserted through the double-sided adhesive tape 21. Is the underside of the last or the upholstery on the insole body 1 3 can be attached set on the lower surface, a set of cushion material 2 is simple.

After the cushion material 2 is set on the insole body 1 in this manner, the lower peripheral lower surface side 32 of the covering is formed by a conventional method.
To the lower surface of the insole body 1 are applied and dried, and then the shoe sole 4 is adhered to the lower peripheral lower surface side 32 of the cover and the lower surface of the insole body 1 to assemble the shoe. Finalize.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the main body 1 of the insole can be easily moved to the last 5 in the same manner as an ordinary insole having no stepped portion when the cover 3 is suspended.
Can be accurately held in close contact with the bottom part of the inner bottom of the inner cover and the lower peripheral upper surface side of the armor cover is adhered to the outer peripheral lower surface of the inner base, as in the case of a normal insole. The cushion material 2 is fitted and set in the cutout portion 11 formed by peeling the peeling piece 12 after the adhesive is applied to the lower surface of the shoe, and the shoe sole is bonded by a conventional method. A shoe in which the cushioning material 2 is set on the center side of the attachment part can be obtained with good comfort.
