DOOR SHUTTER DEVICE
PROBLEM TO BE SOLVED: To provide a door shutter device that causes less malfunction by improving stability of lifting operation of a shutter and has light and good operability.SOLUTION: A door shutter device R comprises following three items: a latch lock A, which locks and unlocks a hinged door D; a shutter unit C, which opens and closes a clearance S between the hinged door D and a floor surface F by interlocking with locking and unlocking operation of the latch lock; and a motion transmitting unit B, which transmits a linear motion that is converted from a rotary motion of a thumb-turn 25 of an operation tool in the latch lock to the shutter unit. When the hinged door in closed state is locked or unlocked, the operation tool of a rotation cam 21 is rotated, which causes the rotary motion of the operation tool to be converted to the linear motion and transmitted, and a movable arm 30 forms a rotation regulation part, which forcibly move the shutter in parallel with a lifting direction of the shutter between a lower stage position to which the shutter is moved down and an upper stage position to which the shutter 55 is moved up, is formed in the lock case M.SELECTED DRAWING: Figure 1
【課題】扉用シャッタ装置において、シャッタの昇降動作の安定性を高めて故障を少なくし、操作性も軽く良好にする。【解決手段】扉用シャッタ装置Ｒは、開き戸Ｄを施解錠するラッチ錠Ａと、ラッチ錠の施解錠動作と連動して開き戸Ｄと床面Ｆとの間の隙間Ｓを開閉するシャッタユニットＣと、ラッチ錠内で操作具のサムタン２５の回転運動を変換した直線運動をシャッタユニットへ伝達する運動伝達ユニットＢの３体からなる。閉状態の開き戸を施解錠するとき、回動カム２１の操作具を回転すると、その回転方向に応じて、操作具の回転運動を直線運動に変換して伝達されると、可動アーム３０はシャッタを降下させる下段位置とシャッタ５５を上昇させる上段位置との間をシャッタの昇降方向に強制的に平行移動させる回動規制部を錠ケースＭに形成する。【選択図】 図１
