PROBLEM TO BE SOLVED: To provide a closing brake for a door that is released to automatically close the door, perform a braking operation in a final closing range, and lets the door continue closing fully at a low speed.SOLUTION: A closing brake for a door includes: a closing device fitted on an upper frame material; a rail device fitted on a top part of a door, the rail device having a rail body with a contacting member in which a sliding member with a plurality of direct-acting dampers may move; and an arm member connected to a shaft center of the closing device and the sliding member. When the door is in an open state, a closing action is obtained by rotating the closing device in a direction to bring back the arm, while the sliding member moves inside the rail body. Resisting force is generated sequentially through stepped contact operations between the direct-action damper and the contacting member, in the final closing range. The deceleration action momentarily slows down the closing door to a low speed, and the door is closed fully to the end without halting.SELECTED DRAWING: Figure 2
【課題】 解放後自動的に扉が閉鎖し、最終閉鎖範囲で制動動作を実施し、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】 上枠に閉鎖装置を装着し、複数の直動ダンパーを備えたスライド部材が当接部材を備えたレール本体内を移動可能に構成されたレール装置を扉上部に装着し、アーム部材を閉鎖装置の軸心とスライド部材とに連結する。扉を開放した状態からは閉鎖装置によるアームの戻る方向への回転動作により、スライド部材がレール本体内を移動しながらの閉鎖動作が得られ、最終閉鎖範囲で直動ダンパーと当接部材との段階的な当接動作により抵抗力を順次発生させ、その減速動作により一旦低速度にまで制動し、そのまま停止することなく最後まで完全に扉を閉鎖させる。【選択図】 図２
