DOOR SHUTTER DEVICE
PROBLEM TO BE SOLVED: To provide a door shutter device that prevents a collision noise between metal members from being widely heard in a room and becoming a discomfort noise by suppressing the collision noise between a metal lock bolt and a bolt gateway.SOLUTION: A latch lock A of a door shutter device R has a cantilever structure in which a ring body 63 of an elastic soundproof ring W is mounted on a port frame 29c of a bolt gateway 29a; a pair of buffer arms 63a, 63b protrude from an inner side of the ring body that faces a latch 15a of a latch bolt 15 passing through the bolt gateway; and the buffer arms incline in symmetrical direction and rise from both sides across the bolt gateway. Even if the latch bolt collides against the bolt gateway, the buffer arms of the soundproof ring warp symmetrically, receive the protruded latch bolt, and flexibly buffer the impact of collision in well-balanced manner; the ring body surrounding the latch warps at the bolt gateway and flexibly buffer the impact of the collision to effectively suppress the collision noise of metal.SELECTED DRAWING: Figure 1
【課題】扉用シャッタ装置において、金属製の錠ボルトとボルト出入口の衝突音を減音して金属部材同士の衝突音が室内に広く響きわたりって不快な騒音になるのを防止する。【解決手段】扉用シャッタ装置Rにおいて、ラッチ錠Aは、ボルト出入口29aの口枠29cに弾性を有する防音リングWのリング本体63を装着し、リング本体に、ボルト出入口を通るラッチボルト15のラッチ15aと向き合う内側に一対の緩衝アーム63a・63bを突設し、ボルト出入口を間に挟んだ両側から対称的な向きに傾斜して立ち上がる片持ち構造にし、ラッチボルトのボルト出入口に衝突しても、防音リングの緩衝アームが対称的に撓み変形し、突出するラッチボルトを受け止めてバランスよく弾力的に衝突の衝撃を緩衝し、ラッチを取り囲んだリング本体がボルト出入口で撓み変形して弾力的に衝突の衝撃を緩衝して金属の衝突音を効果的に減音する。【選択図】 図1
