PROBLEM TO BE SOLVED: To provide a closing brake for a door that automatically closes the door after releasing, without coming to a halt after decelerating in a final stage of closing, and completely closes the door at the decelerated speed.SOLUTION: A closing brake comprises a columnar cam installed rotatably at a central position of a case, the columnar cam having a curved surface and an inclined surface integrated with a shaft center, and a push-in bit energized by a spring member and having a protruded tip disposed to face each other from right and left on an outer peripheral surface of the columnar cam. A slide member is disposed to allow linear motion in a rail body, the slide member having a deceleration member configured to generate a load when a gear rotates. An amplification rack and a braking rack are disposed at an edge part of a rail body, the two racks being linked by a linking gear such that the slide member comes in contact with the amplification rack and the braking rack moves in an opposite direction. An arm member is connected to the shaft center and the slide member, to enable door closing operation from an open state, deceleration operation in a final closing stage, and final closing operation at the decelerated speed.SELECTED DRAWING: Figure 2
【課題】 解放後自動的に扉が閉鎖し、閉鎖最終段階での減速後も停止することなく、そのまま低速度で完全に最後まで閉鎖させることが可能な扉用閉鎖制動装置を提供する。【解決手段】 ケース中央位置に軸心と一体化された湾曲面と傾斜面を有する柱状カムを回動自在に装着し、ばね部材により付勢させた押し込みビットの先端突部を柱状カムの外周面に左右２方向から対向させた状態で配置して閉鎖装置を構成する。歯車の回転動作で負荷が発生する構成の減速部材を有したスライド部材をレール本体内で直線移動可能に配置し、レ−ル本体端部に増幅ラックと移動制動ラックを配置し、スライド部材が増幅ラックに当接し、移動制動ラックが逆の方向に移動するように両者を連動歯車にて連動させる。そしてアーム部材を軸心とスライド部材に連結し、扉を開放した状態からの閉鎖動作と閉鎖最終段階での減速動作と、低速度での最終閉鎖動作を連続して得る。【選択図】 図２
