Description
し、或いは注意を喚起しようとするものである。カラー鉄蓋は概して歩道用マンホール類に多く使用されており、歩行者や自転車等に対する滑り止めとして、防滑剤を混合するような対策もとられている(特開平2-279826号、特開2003-184119号)。しかし特開平2-279826号のものはセラミック溶射が必要であるので設備の問題及びコスト高となるという問題がある。

Claims (5)
- 鉄蓋本体の表面に模様を形成している凸部と凹部を有し、凹部に着色樹脂を充填した構成を有する地下構造物用カラー鉄蓋であって、模様を形成している凸部として、鉄蓋本体の表面に設ける模様を縁取っている突条をほぼ一様な幅で設け、突条で隔てられている領域に、凹部よりも浅い深さの浅凹部を設けたことを特徴とする地下構造物用カラー鉄蓋。
- 浅凹部は、樹脂が充填されない領域を構成している請求項1記載の地下構造物用カラー鉄蓋。
- 凹部に充填されている着色樹脂表面と、浅凹部の表面とは、ほぼ同じ高さ位置にある請求項1記載の地下構造物用カラー鉄蓋。
- 着色樹脂表面及び浅凹部の表面と、突条の表面との間に、鉄蓋表面を通る靴や杖に摩擦抵抗を与え、かつそれらが引っ掛からないだけの高低差が設けられており、高低差は、1.0mm〜2.5mmである請求項1記載の地下構造物用カラー鉄蓋。
- 浅凹部には、スポット状の高まりから成り、突条を越えない高さの小突起を設けた請求項2記載の地下構造物用カラー鉄蓋。
