Description

本発明は、緩衝性と耐久性等を向上させた建材畳床と置き畳に関するものである。   The present invention relates to a building material tatami floor and a tatami mat that have improved buffering and durability.

従来、建材畳床として、図5に示すように、発泡樹脂層11の上に補強材12と緩衝材13とが積層され、裏面材14と一体にされたものが知られている(特許文献1参照)。これは、前記補強材12として、紙およびプラスチックを原料とした成型ボードの畳床である。   Conventionally, as a building material tatami floor, as shown in FIG. 5, a reinforcing material 12 and a buffer material 13 are laminated on a foamed resin layer 11 and integrated with a back material 14 (Patent Document). 1). This is a tatami floor of a molded board made of paper and plastic as the reinforcing material 12.

しかし、従来の建材畳床においては、畳床の加工時の切断加工性は良くなったが、依然として新調の段階で硬すぎると感じたり、繰り返し圧縮によりへたり込み、元に戻らず補強材の硬さを感じるようになったりする課題がある。本発明に係る建材畳床は、このような課題を解決するために提案されたものである。   However, the conventional building material tatami floor has improved cutting workability at the time of tatami floor processing, but it still feels too hard at the new stage, it sags due to repeated compression, and it does not return to its original state. There is a problem that comes to feel the hardness. The building material tatami floor according to the present invention has been proposed in order to solve such problems.

本発明に係る建材畳床の上記課題を解決して目的を達成するための要旨は、建材畳床の表側において、保護材の下でタタミボードの上に、発泡体からなる緩衝材を介在させたことである。
また、建材畳床の表側において、クッション材の下で補強材の上に、発泡体からなる緩衝材を介在させたことである。
前記緩衝材は、無架橋ポリプロピレン型内成形発泡体を成形したものであることを含むものである。
The gist for solving the above-mentioned problems of the building material tatami floor according to the present invention is to provide a cushioning material made of foam on the tatami board under the protective material on the front side of the building material tatami floor. That is.
Further, on the front side of the building material tatami floor, a cushioning material made of foam is interposed on the reinforcing material under the cushion material.
The buffer material includes a non-crosslinked polypropylene in-mold molded foam.

本発明に係る置き畳の要旨は、保護材の表層と、該表層の下に無架橋ポリプロピレン型内成形発泡体を成形した緩衝材とを配設して、これらを逢着若しくは接着等の手段で一体にしてなることである。   The gist of the tatami mat according to the present invention is that a surface layer of a protective material and a buffer material formed by molding an uncrosslinked polypropylene in-mold foam under the surface layer are disposed, and these are attached by means such as adhesion or adhesion. It is to be united.

本発明の建材畳床によれば、この畳床の表側にある保護材若しくはクッション材の下に、発泡体からなる緩衝材を介在させることで、保温性能が向上して人が座る場合に室内温度との差が低減されて快適さが確保される。また、緩衝性能の向上により長時間座るにも適し、転倒時の衝撃を緩和しケガの発生を低減させる。
前記緩衝材により適度な硬さと反発力や復元性が得られて、畳独特の柔らかさが確保され、従来の建材畳床より疲れが少ないものとなる。そして、畳の芯材の上で緩衝性を持たせるので、人の出入りの多いところでも、繰り返しの圧縮に耐えられ畳の芯材のへたりやへこみが出にくくなる。
更に、無架橋ポリプロピレン型内成形発泡体の緩衝材の上に不織布等の保護材を備えることで、縫着した時に生じる糸による発泡体への切り裂き現象を防止すると共に、前記保護材の持つ吸湿性や放湿性を活かすことができる。そして、軽量衝撃音の低減になるとともに寸法安定性が向上する。
また、本発明の置き畳により、畳表若しくは布,不織布等の保護材を表層として内部に前記緩衝材とする組み合わせで、薄肉であって型くずれせず、肌触りの良い簡易的な敷物となる。
According to the building material tatami floor of the present invention, the cushioning material made of foam is interposed under the protective material or cushion material on the front side of the tatami floor so that the heat insulation performance is improved and the person sits down. The difference with temperature is reduced and comfort is ensured. Also, it is suitable for sitting for a long time by improving the buffering performance, reducing the impact at the time of falling and reducing the occurrence of injury.
With the cushioning material, moderate hardness, repulsive force, and restoring property are obtained, the softness unique to the tatami is ensured, and less fatigue than the conventional building material tatami floor. Further, since cushioning is provided on the tatami core material, the tatami core material can withstand repeated compression even in a large number of people coming and going, making it difficult for the tatami core material to sag and dent.
Furthermore, by providing a protective material such as a non-woven fabric on the cushioning material of the non-crosslinked polypropylene type molded foam, it prevents the tearing phenomenon of the foam caused by the thread generated when sewing, and the moisture absorption of the protective material. Can take advantage of the properties and moisture release. And while reducing a light impact sound, dimensional stability improves.
Moreover, by the tatami mat of the present invention, a simple rug that is thin and does not lose its shape without being deformed by a combination of a protective material such as a tatami mat or cloth or non-woven fabric as a surface layer and the cushioning material inside.
