Description

Self assembly mat

The present invention relates to a prefabricated mat, and more particularly, to a prefabricated mat used to protect children from being hurt when laid on the floor of a room, or to prevent interlayer noise in a multi-story building such as an apartment.

Conventionally, as shown in FIG. 1, engagement grooves 3 and protrusions 4 each having a slanting line on both sides 2 are alternately formed on four sides of a square body 1 at regular intervals, A plurality of mats were assembled in such a manner that protrusions were coupled to the coupling grooves in four directions according to the area of the mats.

However, in such a conventional mat, the EVA is foamed in the form of a thick plate, cut into two pieces of the inner skin 1a and the outer skin 1b of necessary thickness, and then the two pieces to be used as the outer skin are respectively provided with a concave- (3) and protruding portions (4) are formed on four surfaces by pressing the body (1) formed by bonding the upper and lower surfaces of the upper and lower surfaces to be used as the inner surface, The manufacturing process is very complicated, and the production cost is greatly increased. In addition, there are problems such that the environmental hormone harmful to the human body is released from the EVA and the surface is worn and the EVA powder is blown and the health is deteriorated.

When the coupling grooves 3 and the protrusions 4 are assembled together and laid on the floor, the side surfaces 2 of the coupling grooves 3 and the protrusions 4 are engaged with each other due to the diagonal lines. Therefore, The upper surface is supported on the floor, but the upper surface is exposed upwardly with the coupling grooves and projections merely in surface contact. Therefore, when the coupling grooves or protrusions are partially compressed or distorted due to pressure repeatedly applied to the upper surface at the time of use, There is a problem in that a safety phenomenon such as a collapse of a child or an accident or the like occurs frequently.

In addition, since the protruded or deformed parts are easily broken and damaged, the assembled state is poor, and the appearance is damaged. Therefore, it is frequently replaced, and thus the life and the replacement cost are wasted there was.

Since the engaging grooves 3 and the ridges 4 are formed on four surfaces by cutting with a press, the shape and spacing of the engaging grooves 3 and the ridges 4 are not the same on all four surfaces, and it is very cumbersome and time- If the connecting portion of the coupling groove and the protruding portion is seen as a complicated line of zigzag, the eyes are easily fatigued, and as the length of the connecting portion becomes longer, the gap for trapping foreign matter such as dust increases, There were also problems such as a lot of time and power for maintenance.

The present invention has been made in view of the foregoing points, and it is an object of the present invention to reduce the production cost considerably and to be harmless to the human body even when used for a long time, The present invention is to provide a prefabricated mat which is very fast, simple and easy to maintain, such as installation and cleaning of assemblies, while preventing wastes of resources and costs or causing eyes to easily fatigue.

In order to achieve the above object, the present invention provides a method for producing a polyurethane foam comprising the steps of: injecting urethane which is harmless to a human body into a mold to form a single square, forming a rectangular shape having a thin thickness on the lower side of the four sides, A first member having a plurality of binding pieces protruding therefrom; a first member having a square shape with the same size and thickness as the first member, And a second member having a plurality of binding grooves formed in an upwardly concave shape in the same shape as the binding piece, and the first and second members are alternately arranged one by one so that the binding pieces are respectively inserted and bound in the binding grooves The coupling pieces are firmly coupled to each other in such a manner that they are inserted into the coupling grooves and are covered with each other. At the same time, And the four sides of the connecting portions of the first and second members are assembled so as to be straight.

In addition, the present invention is characterized in that urethane is injected into a mold to form a single body of triangles of two triangles, and a plurality of rivets, which are selectively inserted into binding grooves formed on four surfaces of the second member, The present invention also provides a prefabricated mat, characterized by further comprising a third member having a binding piece.

According to the present invention, urethane is injected into a metal mold to form a single unit of triangle having a bisector, and the upper and lower members of the first member and the third member are selectively inserted into the lower side of the three sides, And a fourth member provided with a binding groove which is formed in the base.

The prefabricated mat according to the present invention is characterized in that the urethane which is harmless to the human body is injected and foamed into the mold to form the first to fourth members as a single body in a single process, Since the second to fourth members are selectively connected and assembled to the two members or the first and second members, the production cost is greatly reduced and at the same time, the binding members and the coupling grooves on each side are formed in the same shape and spacing, So that it can be assembled and installed.

In addition, even when used for a long period of time, the binding pieces are covered by the binding grooves, so that even when pressure is applied, there is no phenomenon such as protruding upward or being easily deformed or damaged even when pressure is applied, The effect of not wasting costs is not only that the connecting parts are straight, so that even if you watch for a long time, the eyes are not easily fatigued, and the gap where foreign matter such as dust is trapped is minimized, There is also an advantage.
