Description

Non-slip patterned baby slippers}

The present invention relates to children's indoor shoes with a non-slip pattern, and more specifically, to children's indoor shoes with a non-slip pattern that are worn by children to prevent slipping even on slippery floors by applying a non-slip pattern.

Generally, shoes are composed of an upper that protects the instep and ankle area, and a sole that protects the sole and increases friction with the ground to provide benefits for walking, and the sole is coupled to the upper to form a shoe.

Shoe soles are provided to absorb shock that occurs while walking or to minimize slipperiness with the ground. Typically, a number of protrusions are formed on the bottom surface of the shoe sole, and the patterns of the shape of these protrusions are implemented in various ways. These protrusions are not very effective in preventing slipping when walking, especially in places where the floor is flat and the upper surface is wet or wet and slippery. For example, if foreign substances such as moisture or wax are present on the floor of a boat or cabin, or on the upper part of a floor made of tile or marble, which is prone to slipping in a building, slipping cannot be prevented with the protrusions on the sole of the conventional shoe. There is a problem that does not exist.

Additionally, recently, technology has been proposed to more actively prevent slipping by improving the structure of shoe soles.

For example, in Korea Utility Model Registration No. 20-0322538, sandpaper is attached to the bottom of the shoe sole to prevent slipping due to the irregular surface of the sandpaper. In this case, there was a lot of inconvenience because a sandpaper pad had to be attached separately to the bottom of the shoe sole, and the appearance of the shoe was not good because the protruding pattern formed on the sole disappeared due to the attachment of the sandpaper pad.

On the other hand, the protrusion pattern is formed to prevent hydroplaning by discharging moisture that touches the sole of the shoe during rainy weather, but this protrusion cannot be exposed to the outside by the sandpaper pad, which can cause more slipperiness. There is.

In addition, this sandpaper pad had the disadvantage that the adhesive part fell off when walked for a long time, and the rough surface of the sandpaper pad was easily worn due to its weak hardness.

It is composed of a portion 500, an anti-slip portion 600, an adsorption portion 700, a cushion portion 800, and a pattern portion 900.

The children's indoor shoe 1000 with a non-slip pattern of the present invention is a shoe having a shape in which the shoe upper 100 and a body 200 that is coupled to the shoe upper 100 and has a certain thickness are combined.

First, the shoe upper 100 surrounds the instep of the infant's foot and a shoe insertion hole is formed in the center, and the body 200 is coupled to the lower part of the shoe upper.

At this time, the body 200 is composed of 56% by weight of ethylene vinyl acetate resin, 6% by weight of natural rubber, 11% by weight of polyolefin resin, which is a polymer compound, 11% by weight of styrene-butadiene rubber, which is a polymer obtained through emulsion polymerization, and 2% by weight of polymer. , 1% by weight of silicone rubber, 7% by weight of calcium carbonate as a neutralizer, 2% by weight of zinc oxide as an accelerator, 1% by weight of stearic acid as a dispersant, 1% by weight of a crosslinking agent made of a polymer compound with a three-dimensional network structure, and 2% by weight of a foaming agent. The mixed composition can be molded by adding it to an injection foam molding machine and foaming it.

Ethylene vinyl acetate (EVA) resin is determined by the degree of polymerization and the content of vinyl acetate, and has excellent flexibility and impact strength, weather resistance, tear strength, stress crack resistance, and ozone resistance. It is lighter than rubber, and when the content of vinyl acetate is high, flexibility improves, melting point decreases, and adhesiveness improves, and it is compatible with PE (Polyethylene), PP (Polypropylene), PVC (Poly Vinyl Chloride), and rubber. Because it is good, it is mixed and used to improve impact resistance and processability.

Natural rubber is a generally chain-shaped polymer material obtained from plants. Raw rubber is made by cutting a Para rubber tree to collect latex, which is the sap, and then coagulating and drying it. Raw rubber has many defects in that it cannot be used as is in daily life due to its high adhesiveness and severe change in elasticity, so bridging is a bond that is formed as if a bridge is being formed between atoms that are bonded in a chain between molecules by reacting raw rubber with sulfur, etc. It is manufactured and used through a vulcanization method to form a .

Polyolefine resin is a polymer compound produced by polymerization of olefin, a chain-shaped hydrocarbon compound with one double bond. It is the lightest among plastics and has excellent transparency. It has a melting point of 350℃ and a heat distortion temperature of 200℃. It has a heat resistance of ℃.

Styrene-butadiene rubber (abbreviated as SBR) is a polymer obtained by emulsifying and polymerizing styrene and butadiene in a ratio of about 1:3. It is a representative synthetic rubber and has excellent abrasion resistance, aging resistance, and heat resistance. , the properties are almost the same as natural rubber, so it can be vulcanized with sulfur.

Polymers are compounds made up of molecules in which one or several types of structural units are polymerized and connected to each other through a large number of chemical bonds. Examples include vinyl chloride and nylon.

Next, the shock absorber 300 is formed on the upper surface of the body 200 and includes an air receiving unit 310 that accommodates air in the internal space, and air flowing into one side of the air receiving unit 310. An air inlet 320 is formed to allow air to flow out.

At this time, the shock absorber 300 is disposed between the body 200 and the insole (not shown), and an air layer is formed to absorb shock applied from the ground to the entire sole of the foot.

The folding inducing portion 400 is formed at regular intervals from the front to the rear of the bottom surface of the body 200 and is recessed so that both sides are connected.

At this time, the folding inducing portion 400 is provided so that the body 200 can be flexibly folded so that the body 200 forming the outsole does not interfere with the movement of the wearer's feet and toes, and the detailed configuration will be described later.

Next, the balance maintenance portion 500 is formed to protrude at regular intervals along the edge of the bottom surface of the body 200.

At this time, the balance maintenance part 500 is disposed along the edge of the body 200 and is formed so as not to interfere with the folding inducing part 400.

And the balance maintenance part 500 protrudes from the floor toward the ground and may be formed in a spike shape.

Additionally, the anti-slip portion 600 is disposed at a position corresponding to the forefoot portion of the bottom surface of the body 200, and mountains and valleys are formed in a lattice shape on the body 200.

At this time, the anti-slip portion 600 is detachably coupled to the bottom surface of the body 200 and is made of a material with a higher coefficient of friction than the body 200.

Next, the adsorption unit 700 is disposed at a position corresponding to the center of the bottom surface of the body 200 and is detachably coupled to the protrusion unit 510 that protrudes at regular intervals. It is configured to include an adsorption unit 520 in which a groove is formed on the cross section in contact with the ground.

Here, the protrusion unit 510 protrudes from the center of the bottom surface of the body 200 and is formed in a spike shape.

And the suction unit 520 is fitted into the protrusion unit 510, and the upper part coupled to the protrusion unit 510 is formed with a coupling groove (not shown) in which the end of the protrusion unit 510 is accommodated, In the lower part, a groove (not shown) of a predetermined depth is formed on the central portion of the end surface.

At this time, as the inside of the space formed through the groove is maintained in a vacuum state after the air has escaped, a vacuum adsorption state is maintained between the adsorption unit 700 and the bottom surface.

When the wearer continues to walk, the adsorption unit 700, which was maintained in the adsorption state, is tilted and the air escapes to the outside, thereby breaking the compression state, and the other adsorption unit 700, which is formed thereafter, is pressed again to the floor surface. It maintains adsorption with cotton.

When this process is carried out continuously, the adsorption function with the floor surface by the plurality of adsorption units 700 is exerted, making it possible to prevent slipping even on a slippery floor.

Next, the cushion part 800 is disposed at a position corresponding to the heel part of the bottom surface of the body 200, and is made of a material with higher elasticity than the balance maintenance part 500.

Here, the cushion portion 800 is disposed at a position corresponding to the heel portion of the body 200, and when formed to be in contact with the ground so that the air in the shock absorbing portion 300 is embedded, it is protected from sharp foreign substances. This can cause tearing problems.

Accordingly, in the present invention, the cushion part 800 is made of a rubber material with its own elastic force and is formed to protrude from the lower part of the body 200, and includes the balance maintenance part 500, the anti-slip part 600, and the adsorption part. The protruding height is higher than that of (700).

That is, the cushion part 800 protrudes more than the balance maintenance part 500, the anti-slip part 600, and the adsorption part 700 so that it touches the ground first when walking, so that the cushion part 800 touches the ground first. The heel can be protected from the shock applied when walking.

Next, the pattern portion 900 is formed on the forefoot, central, and heel portions of the bottom surface of the body 200, and ridges and valleys are repeatedly formed.

Here, the pattern portion 900 is formed in various shapes on the bottom surface of the body 200 and is formed in the shape of peaks and valleys to prevent slipping when in contact with the ground while walking.

The pattern portion 900 is arranged in different shapes in the space partitioned by the folding inducing portion 400.

At this time, the folding inducing portion 400 has a first tangent line 410 disposed at a position corresponding to the toe root (toe) on the forefoot portion of the body 200, and a second tangent line 420 disposed between the forefoot portion and the central portion. and a third tangent 430 disposed between the central portion and the heel portion, and a fourth tangent 440 disposed between the second tangent 420 and the third tangent 430.

First, the first tangent 410 is formed at a position corresponding to the toe where the user's sole and toe are connected, and is recessed to connect both sides of the body 200, and the user's toe is positioned above or above the sole. When folded in the downward direction, the body 200 can be guided to fold along.

The second tangent line 420 is disposed between the forefoot portion and the central portion of the body 200 and is formed to be curved between the forefoot portion and the central portion to connect both sides of the body 200.

Additionally, the third tangent line 430 is disposed between the central portion and the heel portion and is recessed to connect both sides of the body 200.

Next, the fourth tangent 440 is disposed between the second tangent 420 and the third tangent 430 and is recessed to connect both sides of the body 200.

And the first to fourth tangent lines 210, 220, 230, and 240 are formed parallel to each other and each is recessed in the lower surface of the body 200 so that it can be folded in the direction where the front and rear ends of the body 200 meet. is formed.

Here, a space defined in the area of the body 200 is formed through the first to fourth tangents 210, 220, 230, and 240.

At this time, a pattern portion 900 is formed in each partitioned space. The pattern portion 900 is disposed between the first tangent line 410 and the second tangent line 420 and is formed in the horizontal direction to connect both sides. A first anti-slip pattern 910, a second anti-slip pattern 920 disposed between the second and third tangents 420 and 430 and formed in a circular shape, and the third anti-slip pattern 910, and A third anti-slip pattern 930 is formed between the fourth tangent lines 440 and formed in a diagonal direction.

First, the first anti-slip pattern 910 is formed between the first tangent line 410 and the second tangent line 420, and is formed in the horizontal direction to connect both sides.

At this time, if the first anti-slip pattern 910 is formed so that both ends are fixed to both sides of the body 200, it can be designed into various shapes such as a wave pattern.

The first anti-slip pattern 910 is a pattern for preventing slipping against the ground due to the total force when the forefoot contacts the ground while walking, and is formed in the horizontal direction of the body 200.

And the second anti-slip pattern 920 is disposed between the second tangent line 420 and the third tangent line 430 and is formed in a circular shape, and is formed by repeating peaks and valleys.

The second anti-slip pattern 920 is made of circular peaks and valleys whose diameters gradually increase from the center to the outside. At this time, it is formed in a circular shape at a position corresponding to the instep to prevent slipping in the forward, backward, left and right directions.

Next, the third anti-slip pattern 930 is disposed between the third tangent line 430 and the fourth tangent line 440 and is formed diagonally with respect to the body 200.

Here, the third anti-slip pattern 930 is formed so that diagonal lines slanting to the left and diagonals slanting to the right overlap each other so that the peaks and valleys overlap to form a diamond shape.

At this time, the third anti-slip pattern 930 is disposed between the heel and the instep to prevent slipping by improving friction with the ground at the heel position where body weight is applied.
