DOOR SHUTTER DEVICE
PROBLEM TO BE SOLVED: To provide a door shutter device that can prevent a collision noise between metals from being widely heard in a room and becoming a discomfort noise by suppressing the collision noise of a shutter.SOLUTION: In a door shutter device, a hinged door is unlocked and a shutter 55 moves up. A shutter guide 65 disposed between the shutter 55 and a shutter case is made of elastic material that can warp. When the shutter guide is installed in the shutter 55, buffer arms 70, 71 having cantilever structure, which extend in a direction between the shutter 55 and the shutter case, protrude from a spacer part 65a.SELECTED DRAWING: Figure 1
【課題】シャッタの衝突音を減音して金属同士の衝突音が室内に広く響きわたり、不快な騒音になるのを防止できる扉用シャッタ装置を提供する。【解決手段】開き戸が解錠されてシャッター５５が上がる扉用シャッタ装置において、シャッタ５５とシャターケース間に設けられるシャッタガイド６５は、撓み可能な弾性材からなり、シャッタ５５に組み付けたとき、シャッタ５５とシャッタケースの間に介在する向きに伸びる片持ち構造の緩衝アーム７０、７１がスペーサ部６５ａに突設される。【選択図】図１
