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.

In the waterproof shoe according to the present invention, a covering layer of thin rubber 3 is provided on the surface of a sock-like fabric 1 to form a shoe body 4, and an articulator 7 is provided on two strips of tape 6 on both sides of a fastener 8. A fastener unit is constructed by bias sewing 14 a cotton cloth 9 with a rubber coating 15 on the outer surface, and attaching a sole 16 to the lower surface of the shoe body 4, and arranging the fastener unit longitudinally inside the shoe body 4. The rubber coating 15 of the fastener unit is adhered to the shoe body 4, and a coating layer of thin reinforcing rubber 10 is provided at appropriate locations including the peripheral edge of the fastener unit and the part spanning the shoe body 4,
A vertical incision 13 is provided by shifting the shoe body 4 from the articulator 7 in the overlapped part with the fastener 8, so that the upper ends of the fabric 1, thin rubber 3, fastener unit, and thin reinforcing rubber 10 are on the same horizontal plane. This is what I did.

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. A fastener unit is constructed by sewing a cotton cloth 9 having a rubber coating 15 on the outer surface side to the side edge of the fastener 8 by bias sewing 14, and attaching the fastener unit to the foot. The mold 2 is placed vertically on the upper part of the heel part 5 inside the rear of the shoe body with the mold 2 inserted, and the fastener 8 is adhered through the rubber coating 15 of the cotton fabric 9, and the outer surface of the rubber coating of the cotton fabric 9 and the shoe are bonded together. After covering the main body 4 with a thin reinforcing rubber 10 and vulcanizing the thin rubber 3 and the thin reinforcing rubber 10, the shoe main body 4 is removed from the foot mold 2, and a linear incision is made in the shoe main body 4. One tape 6
It is characterized in that it is provided along the side edge of the shoe up to the shoe opening at the upper end of the shoe, and the fabric 1 at the upper end of the shoe opening is cut off.

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. After bias sewing 14 cotton cloth 9 to the side edge of the fastener 8 where the articulator 7 is provided, a rubber coating 15 is provided on the outer surface to form a fastener unit, and the leg mold 2 is inserted into the fastener unit. A thin reinforcing rubber 10 is disposed vertically on the upper part of the heel part 5 on the inside of the rear part of the shoe body in a state where the rubber coating 15 of the cotton fabric 9 is adhered to the outer surface of the rubber coating of the cotton fabric 9 and the shoe body 4.
and thin rubber 3 and thin reinforcing rubber 10.
After the shoe body 4 is vulcanized, the shoe body 4 is removed from the foot mold 2, and a linear incision 13 is made in the shoe body 4 so as to be offset from the occlusal line 11 at the center of the fastener, and at the side edge of one tape 6. It is characterized in that it is provided along the edge up to the shoe opening at the upper end of the shoe, and the fabric 1 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, reference numeral 1 is a sock-like fabric made of stockinette knitted with nylon or cotton threads for 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.
The fastener 8 provided with the fastener 8 is arranged vertically, and a cotton cloth 9 (see FIG. 8) having a rubber coating 15 is sewn onto the side edge of the fastener 8 by bias sewing 14.
to configure the fastener unit (see Figure 9),
A rubber coating 15 of cotton fabric 9 is attached to the fastener unit.
It is attached to the outer surface of the shoe body 4 via. The cotton cloth 9 having the rubber coating 15 may be made by impregnating the cotton cloth 9 in latex, or the surface of the cotton cloth may be coated with rubber.

Furthermore, instead of the cotton cloth having the rubber coating 15, the tape 6 is made of cotton cloth 9 without a rubber coating (see No. 10).
After bias sewing 14 (see Figure 11),
Rubber coating 1 by impregnating the cotton cloth part in latex
5 may be made to constitute a fastener unit (see FIG. 12).

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

Next, the sole 16 is attached to the shoe body 4 coated with the thin reinforcing rubber 10, and the hindfoot mold 2 that has been vulcanized is removed.

Then, as shown in FIGS. 5 and 6, after the occlusion elements 7, 7 of the fastener 8 are removed by lowering the slider 17, the fastener 8 is moved so that it deviates from the occlusion line 11 at the center and along the tape side edge on the rear side. A linear incision 13 is provided in the shoe body 4 at the position from the lower end of the fastener 8 to the shoe opening at the upper end of the shoe.

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.

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 slider 17 is pulled down toward the heel portion 5 to insert the foot, and then the slider 17 is pulled up toward the shoe opening to be worn.

[Effects of the invention] Since the shoe body is composed of fabric 1 with high flexibility and elongation rate and thin rubber 3, when in use, it fits well and comfortably on the foot, and the fastener 8 makes it easy to put on and take off the foot. Since the fastener 8 is easily bonded to the cotton cloth 9 through the rubber coating 15, it also has sufficient strength.
