Description

Individual Mat for Assembly {Element Mat for Assembly}

The present invention relates to an individual mat for assembling, and more particularly, by assembling it in the form of a mat having a cushion function on the indoor floor of a general home or multi-purpose facility (kids cafe, nursing home, etc.) It relates to an individual mat for assembly capable of preventing noise between floors.

In general, cushion mats are used for the purpose of preventing falls and noise between floors, preventing musculoskeletal disorders and relieving fatigue in places such as homes and multipurpose facilities such as kids' cafes and nursing homes.

These cushion mats are assembled by connecting small square or rectangular individual mats to each other for easy installation and removal as needed, but simply assembling by forming interlocking projections and grooves around the individual mats, a large area is constructed.

In relation to such a mat, as shown in FIG. 1, in the related art, as shown in FIG. 1, coupling grooves and protrusions in which both sides are oblique lines on the four sides of the body having a square plate shape are alternately formed one by one at regular intervals to form an indoor floor According to the area of the assembling a plurality of protrusions in a way to connect in all directions by coupling the protrusion to the coupling groove, it is laid on the floor of the installation space.

However, in the case of the above-mentioned conventional mat, since the connection part combined with the coupling groove and the protrusion is made of a complicated zigzag line, it not only increases eye fatigue, but also increases the length of the connection part so that foreign substances such as dust are caught. There was a problem that maintenance such as cleaning was difficult because there were many gaps.

In addition, as shown in FIG. 2 in relation to other conventional mats, coupling grooves and protrusions are formed on the four sides of the square body like the conventional mat described above, but the coupling grooves and protrusions are not formed in the entire thickness of the body, but about half of the bottom. It is formed only in the thickness and not over the entire side of the body, but is formed only in a part of the body.

However, since all of these assembly mats are made of polyurethane foam for their own purpose, they are soft and elastic, so when pressure or force is applied to the assembly connection part, it is easy to open a gap, and when water or beverage falls on the mat, it seeps into the gap. There is a risk of damage, such as water rotting or deforming the floor below. Furthermore, dust can also enter the crevice, and in the case of dust, when the user steps on the raised space of the mat and the floor during activity, the compressed air comes out through the crevice and scatters the dust.

In addition, if a gap is easily formed between mats and only one side of the assembly connection part between adjacent individual mats is pressed, a step may occur and a foot jam may occur. There was a problem that could cause safety accidents such as tripping or, in severe cases, fractures of fingers or toes.

In addition, due to the nature of the mat made of foam material, the coefficient of contraction and expansion according to temperature is rather large. However, in the case of a structure that does not have sufficient strength to hold the connection between the mats, there is a problem that a gap between the mats may occur depending on the temperature even if there is no external force. .

In order to solve these problems, insert foaming can be made to insert a hard implant to firmly bind the urethane foam during foaming, but insert foaming makes the conventional injection process complicated and cumbersome, and there is a problem of cost increase due to the addition of members. can

On the other hand, in the case of forming a cushion mat only with polyurethane foam, the liquid may be absorbed into the surface if water or other beverages are poured on it due to the nature of the porous material, and it is difficult to finish it smoothly in appearance, and there is a possibility of surface damage such as scratches by external force. Recently, there is a case of making a product by bonding a polyurethane skin layer such as TPU (thermoplastic polyurethane) to the upper surface of the polyurethane foam.

This configuration is usually made through polyurethane foam injection molding in which a TPU skin layer is first installed in an injection mold, and polyurethane foam is injected thereon.

However, in such a configuration, due to the bubbles of the polyurethane foam during injection molding, the actual contact area between the polyurethane foam layer and the TPU skin layer becomes small, and the adhesive force is weakened, so that peeling or lifting between the two layers occurs easily, thereby reducing the commercial properties.

And even in this configuration, if the TPU skin layer is thickened, the cushioning feeling is reduced and elasticity is lowered, so if a force is applied from the side, the peeling phenomenon between the TPU skin layer and the polyurethane foam layer occurs more easily. As the gap between the two mats increases, a thin epidermis layer is used as the gap between the two mats becomes wider. There was a problem in that it was difficult to sufficiently solve the problems of the conventional assembling mat, such as scratch prevention and the opening and separation of the connection part due to external force or environmental factors.

In addition, the TPU skin layer can prevent substances such as beverages from penetrating into the foam when beverages are spilled on the surface of the mat. The material is easily absorbed into the foam mat bottom surface before wiping off the drinking water on the floor and it is difficult to remove. there was

In the above, in integrally molding each layer of the mat body part 10, that is, the base foam layer 11 and the integral surface layer 13, the integral surface layer 13 including the film skin layer 15 was placed in a mold. Next, the urethane foaming stock solution for forming the base foaming layer 11 is injected into the mold, and then heated to foam molding. That is, since the polyurethane foaming undiluted solution of the base foaming layer 11 foams and is fused to the thermoplastic polyurethane fabric in a semi-melting state constituting the integral surface layer 13, it is integrated with the thermoplastic polyurethane fabric. It is possible to integrally mold the integral surface layer 13 to be formed and the base foam layer 11 formed by foaming of the polyurethane foaming stock solution without a separate adhesive means.
