[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a children's rain boot whose pattern on the ground changes as it is worn.

[0002]

2. Description of the Related Art Recently, the outer sole of a child wears rain boots when it rains, as shown in a plan view of FIG. 5 and a lower surface (1) as shown in FIG. An outer bottom (4) having a raised portion (2) capable of forming a pattern on a soft ground in rainy weather has been put to practical use for the purpose of imparting anti-slip properties.
Such children's rain boots have a certain effect because they are configured such that animals, creatures, plants, and main characters of animations, etc., which are preferred by children, are formed on the ground.

[0003]

The above-mentioned rain boots were sufficiently effective in the initial stage of wearing, but were repeatedly worn, so that the lower surface (1) of the outer sole (4) could be obtained.
When the raised portion (2) formed on the surface is worn out, it is no longer possible to form such a pattern that the child likes as described above on the ground, and the child does not want to wear rain boots even in rainy weather, and the skid resistance is reduced. It also had the disadvantage of disappearing.

[0004]

As shown in the plan view of FIG. 1, the sectional view of FIG. 1 and the sectional view taken along the line A--A of the present invention, the lower surface (1) has a convex which can form a first pattern on the ground. A concave portion having a raised portion (2) and capable of forming a second pattern on the ground when the raised portion (2) is worn out by repetition of wear and becomes flush with the lower surface (1); The subject matter is a children's rain boot having an outer sole (4) wherein the part (3) is configured to protrude near the lower surface (1). The outer bottom (4) is made of natural rubber, styrene butadiene copolymer rubber, polyisoprene rubber, polybutadiene rubber, acrylonitrile butadiene copolymer rubber,
An outer bottom (4) made of polyvinyl chloride, polyurethane, ethylene-vinyl acetate copolymer or the like, and usually formed of the same material as shown in FIG. 2, is used.

[0005] In order to make the concave portion (3) capable of forming the second pattern appear quickly and to realize the effect of the present invention within a short time, the first pattern is formed as shown in FIG. A material that is particularly worn is used as the raised protrusion (2). For example,
In the case of the rubber, a large amount of white sub, machine oil, motor oil,
Turbine oil and the like are blended. In the case of polyvinyl chloride, a semi-gelled one is used.

[0006] The base part (5) having the raised part (2) capable of forming the first pattern and the concave part (3) capable of forming the second pattern is separated from the base part (5) by, for example, injection molding by two-step punching. Law,
The outer bottom (4) can be manufactured by a method of separately vulcanizing each of them, thereafter sticking them together and integrating them. The combination of the first pattern and the second pattern is a combination that is related to each other so that the child can wear rain boots forever, for example,
Tadpoles and frogs, flowers and apples, eggs and chicks, waves and ships, approaching clouds and rainbows, stars and rockets, soap bubbles and kindergarten landscapes, grass and mantis, grass and mantis, peach and Momotaro, snow and snowman.

[0007]

[Operation and Effect] On the lower surface of the outer sole (4) used in the rain boots of the present invention, a protruding part (2) that can form a pattern on the ground at an early stage during wearing is rubbed for a while. Has decreased,
Even if the first pattern is not formed, a recess that can immediately form the second pattern appears near the lower surface (1), so that the second pattern can be formed on the ground, and the child gets tired. I will gladly wear rain boots. Also, anti-slip properties are added.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. A combination of a lower mold and a dummy mold having an engraved surface capable of forming a tadpole of a raised portion (2) and a frog of a concave portion (3) in a hollow portion, under conditions of an injection cylinder temperature of 150 ° C. and an injection pressure of 800 kg / cm ² . In suspension polymerization polyvinyl chloride (average degree of polymerization 1000, 3
% Vinyl acetate copolymer) 100 parts by weight, DOP 50 parts by weight,
20 parts by weight of polyester auxiliary plasticizer, 10 parts by weight of tribasic lead sulfate, 1 part by weight of lead stearate, calcined kaolin 1
A kneaded material consisting of 0 parts by weight, 20 parts by weight of light calcium carbonate, and 5 parts by weight of titanium oxide is injected, and then the dummy mold is removed to have a cavity having a sculptured surface capable of forming a base part (5) on the lower surface. The kneaded product obtained by replacing the titanium oxide in the kneaded product with 5 parts by weight of the kneaded material with 3 parts by weight of cadmium yellow was injected under the conditions of an injection cylinder temperature of 180 ° C. and an injection pressure of 800 kg / cm ² in combination with the upper mold. I got

The outer bottom (4) is attached to the lower surface of a waterproof polyamide fiber sheath (6) shown in FIG.
The children's rain boots of the present invention were obtained. One of these shoes in the rainy season
When a child wears it for 0 days, the tadpole (2) is copied to the ground during that period, after which the tadpole (2) is not copied to the ground, but instead the frog (5) is copied to the ground. Became.
