Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to waterproof shoes used in agricultural work, construction sites, etc.

[Prior art] Conventionally, this type of waterproof shoes was made by sewing a woven fabric with vinyl chloride, rubber, etc., but the woven fabric itself did not stretch well, and the rubber attached to it did not stretch well. Because they are hard, they are difficult to fit around the foot when in use, and they also have drawbacks such as being uncomfortable to wear.

[Problems to be Solved by the Invention] The present invention aims to provide durable waterproof shoes that are easy to process.

[Means for solving problems] This will be explained with reference to the drawings.

The waterproof shoes according to the present invention include a shoe body 4 formed by providing a covering layer of thin rubber 3 on the surface of a sock-like fabric 1, a fastener 8 in which an articulator 7 is provided on two strips of tape 6, and an excess waterproofing material. The sheets 16 are arranged overlappingly to form an overlapping body 17, and the cotton cloth 9 with the outer surface of the rubber coating 15 is sewn onto both sides of the overlapping body 17 by bias sewing 14.
A fastener unit is constructed by attaching the sole 18 to the lower surface of the shoe body 4, and arranging the fastener unit longitudinally inside the shoe body 4.
The surplus waterproof sheet 16 is bonded to the shoe body 4 through the rubber coating 15 of the fastener unit, and a coating layer of thin reinforcing rubber 10 is provided at appropriate locations including the peripheral edge of the fastener unit and the portion spanning the shoe body 4. A long groove-shaped cutout 13 is provided in the shoe body 4 at the overlapped portion with the shoe body 4, and the upper ends of the fabric 1, thin rubber 3, fastener unit, and thin reinforcing rubber 10 are arranged on the same horizontal plane.

In addition, the method for manufacturing waterproof shoes according to the present invention includes leaving the upper end of the shoe opening on the surface of the sock-like fabric 1 and covering it with thin rubber 3 having high flexibility and elongation to form the shoe body 4, and forming the shoe body 4 with two strips of tape 6. An overlapping body 17 is formed by overlapping the surplus waterproof sheet 16 on the fastener 8 on which the articulator 7 is provided, and a cotton cloth 9 having a rubber coating 15 on the outer surface side is attached to the side edge of the overlapping body 17. By bias sewing 14, the fastener unit is adhered to the upper part of the heel part 5 on the inner rear side of the shoe body 4 with the foot mold 2 inserted through the rubber coating 15 of the cotton fabric 9, and the rubber coating 15 of the cotton fabric 9 is attached. After covering the outer surface and the shoe body 4 with a thin reinforcing rubber 10 and vulcanizing the thin rubber 3 and the thin reinforcing rubber 10, the shoe body 4 is removed from the foot mold 2, and the surplus waterproof sheet 16 is removed. This shoe is characterized by providing a long groove-shaped incision 13 in the shoe body 4 located on the inside and cutting off the fabric at the upper end of the shoe opening.

Furthermore, the method for manufacturing waterproof shoes according to the present invention involves leaving the upper end of the shoe opening on the surface of the sock-like fabric 1 and covering it with thin rubber 3 having high flexibility and elongation to form the shoe body 4, and then attaching two strips of tape 6 to the shoe body 4. An overlapping body 17 is formed by overlapping the surplus waterproof sheet 16 on the fastener 8 where the articulator 7 is provided, and after bias sewing 14 the cotton cloth 9 to the side edges of the overlapping body 17, the outer surface of the cotton cloth 9 is sewn. A fastener unit is formed by providing a rubber coating 15 on the side, and the fastener unit is adhered to the upper part of the heel part 5 on the inside of the rear part of the shoe body 4 with the foot mold 2 inserted through the rubber coating 15 of the cotton cloth 9. At the same time, a thin reinforcing rubber 10 is applied over the outer surface of the rubber coating of the cotton fabric 9 and the shoe body 4, and the thin rubber 3 and the thin reinforcing rubber 10 are vulcanized, and then the shoe body 4 is removed from the foot mold 2. In addition, surplus waterproof sheet 1
A long groove-shaped incision 1 is made in the shoe body 4 located inside the shoe body 6.
3 and the fabric at the upper end of the shoe opening is cut off.

[Example] An example of the present invention will be described based on the drawings.
Note that all the illustrated shoes are examples of shoes for the left foot.

In FIG. 2, numeral 1 is a sock-like fabric made of stockinette knitted with nylon or cotton threads so as to have good stretch. Reference numeral 3 denotes a thin rubber coated by coating or pasting latex on the surface of the fabric 1, leaving the upper end of the shoe opening portion intact.

In this way, the shoe body 4 is formed by covering the entire surface of the knitted sock-like fabric 1 with the thin rubber 3 and into which the foot mold 2 is inserted.

Next, as shown in FIG.
An overlapping body 17 is formed by overlaying the excess waterproof sheet 16 on the fastener 8 provided with
) are bias sewn 14 to form a fastener unit (see FIG. 9), and the fastener unit is attached to the outer surface of the shoe body 4 via a rubber coating 15. The cotton cloth 9 having the rubber coating 15 may be made by impregnating the cotton cloth 9 in latex, or
Alternatively, the surface of the cotton cloth 9 may be coated with rubber.

Furthermore, instead of the cotton fabric 9 having the rubber coating 15, a cotton fabric 9 without a rubber coating 9 (see FIG. 10) is bias-sewn 14 to the tape 6 (see FIG. 11), and then the cotton fabric portion is impregnated in latex. A fastener unit may also be made (see Figure 12).

Further, as shown in FIG. 4, a thin rubber 10 is coated so as to extend over the outer surface of the cotton cloth 9 and the shoe body 4.

Next, the sole 18 is attached to the shoe body 4 covered with the thin reinforcing rubber 10, and the hindfoot mold 2, which has been vulcanized, is removed.

Then, as shown in FIGS. 5 and 6, the occlusion piece 7 of the fastener 8 is removed by lowering the slider 19, and then attached to the shoe body 4 along both side edges of the tape from the lower end of the fastener 8 to the shoe opening at the upper end of the shoe. A long groove-shaped incision 13 is provided.

Furthermore, the fabric 1 remaining at the upper end of the shoe body 4 at the step shown in FIG. 4 is cut off and removed as shown in FIG.

The surplus of the surplus waterproof sheet 16 refers to the surplus of the surplus waterproof sheet 16.
This refers to the length that is left over from the horizontal length of the circumferential surfaces connected by the wire, and that surplus length is always stored by bending. This is the change in the length of the circumferential surface when the fastener 8 is opened, or in other words, the length that allows the fastener 8 to open.

Further, although the figure shows non-finger type waterproof shoes, it goes without saying that the present invention can also be applied to toe type waterproof shoes.

[Function] The present invention is configured as described above, and when the fastener 8 is opened, there is an extra waterproof sheet 16 overlapping this, so regardless of whether the fastener 8 is opened or closed, water is prevented from entering from this part. It can fully protect the waterproof ability of waterproof shoes.

[Effects of the Invention] According to the present invention, a fastener opening/closing structure for easy wearing is provided, and it is completely waterproof.
