ソフトブロックに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft block, and more particularly, to a soft block for play in which an infant rides, stacks and plays, or a soft block usable as a floor material or the like.
【０００２】[0002]

せるのが一般的である。2. Description of the Related Art Up to now, there has been known a soft block for play, which is mainly used by an infant or the like to ride or stack. As a material for such soft blocks,
Foamed polyethylene and foamed EVA (ethylene-vinyl acetate copolymer) are known. By the way, in the production of such a soft block, it is general to slice a foamed raw fabric and to bond the sliced raw fabric.

【発明が解決しようとする課題】しかしながら、こうし
た方法で製作されたソフトブロックの表面は平滑でな
く、微細な凹凸を有している。このため、遊戯中にソフ
トブロック表面が汚れ易く、また一旦ついた汚れがなか
なか落ちにくいという問題点を有している。However, the surface of the soft block manufactured by such a method is not smooth and has fine irregularities. For this reason, there is a problem that the soft block surface is easily soiled during play and that stains once deposited are difficult to remove.
【０００４】そこで、この問題点を解消する手段とし
て、表面を塗料等でコーティングすることが考えられ
る。しかし、この方法は最も簡単な方法であるが、通常
の塗料では塗膜が硬くなるため、ブロックの変形に追従
できない。Therefore, as a means for solving this problem, it is conceivable to coat the surface with paint or the like. However, although this method is the simplest method, it cannot follow the deformation of the block because the coating film becomes hard with ordinary paint.
【０００５】この発明はこうした事情を考慮してなされ
たもので、プラスチック製発泡体の表面に弾性を有する
被膜を設けることにより、表面が汚れにくく、また仮に
汚れても容易に汚れをおとすことができ、更に発泡体の
変形に追従可能なソフトブロックを提供することを目的
とする。The present invention has been made in view of the above circumstances, and by providing an elastic coating on the surface of a plastic foam, the surface is less likely to be soiled, and even if soiled, it can be easily soiled. It is an object of the present invention to provide a soft block that can be formed and can follow the deformation of the foam.

特徴とするソフトブロックである。この発明において、
前記プラスチック製発泡体の材料としては、例えばポリ
エチレン，エチレン−酢酸ビニル共重合体（ＥＶＡ），
ポリウレタン，ポリ塩化ビニルが挙げられる。The present invention is a soft block characterized in that the surface of a plastic foam is coated with an elastic film. In this invention,
Examples of the material of the plastic foam include polyethylene, ethylene-vinyl acetate copolymer (EVA),
Examples include polyurethane and polyvinyl chloride.
【０００７】この発明において、前記被膜としては、引
張強度６０〜１８０Ｋｇｆ／ｃｍ2、伸び約２００％で
あることが好ましい。この理由は、引張強度が６０Ｋｇ
ｆ／ｃｍ2 未満ではソフトブロックが加圧されたとき、
被膜が破断しやすくなり、耐久性に問題が生じるからで
ある。また、引張強度が１８０Ｋｇｆ／ｃｍ2 を越える
と、被膜が硬くなり、良好な感触を得られなくなるから
である。更に、伸びを約２００％としたのは、ブロック
加圧時の変形量を考慮し、充分に追従できるとの判断か
らである。In the present invention, the coating preferably has a tensile strength of 60 to 180 Kgf / cm 2 and an elongation of about 200%. The reason for this is that the tensile strength is 60 kg.
Below f / cm 2 , when the soft block is pressed,
This is because the coating film is likely to break and a durability problem occurs. Also, if the tensile strength exceeds 180 kgf / cm 2 , the coating becomes hard and a good feel cannot be obtained. Further, the reason why the elongation is set to about 200% is that it can be sufficiently followed in consideration of the deformation amount when the block is pressed.

れたりするため、好ましくない。）In the present invention, examples of the coating film include those obtained by coating the surface of the foam with a coating material containing urethane paint, vinyl chloride resin, and acrylic resin as a main raw material. (Note that
A coating agent containing vinyl chloride or urethane as a main raw material cannot follow the deformation of the foam, and the coating film is cracked or peeled off, which is not preferable. )

成することにより得られる。According to the soft block of the present invention, the raw material of the foam is sliced and laminated to form a plastic foam having a predetermined shape, and then a coating agent containing, for example, an acrylic resin as a main material is applied to the surface of the foam. It is obtained by coating the above to form a film.
