DOOR CLOSER IN WHICH TWO LINK DEVICES SIMULTANEOUSLY OPERATE AND STOP
To provide a door closer that stops a door that suddenly accelerates in an opening direction by a blast of wind when the door is opened.SOLUTION: A door closer includes: a link device that operates only when a door is closed and does not operate when the door is opened; and a link device that operates only when the door is opened and does not operate when the door is closed. The two link devices are interchanged when the door is fully closed and simultaneously operate and stop. A decelerator in which a steel ball that falls with dead weight is used as replacement of sand in a sandglass includes a moving body that follows a discharge speed of the steel ball. The decelerator resists a large force and requires almost no power to operate.SELECTED DRAWING: Figure 23
【課題】ドアを開くときに、突風に煽られて開く方向に急激に加速するドアを停止させるドアクローザを提供する。【解決手段】ドアが閉まるときだけ動作して開くときには動作しないリンク装置と、ドアが開くときだけ動作して閉まるときには動作しないリンク装置とを備え、２つのリンク装置はドアが全閉するときを境にして入れ替わり、同時に動作して停止する。砂時計の砂を自重で落下する鋼球に取り換えてなる減速器は、鋼球の排出速度に従う移動体を備える減速器で、大きな力に抵抗して、しかも動作させるに殆ど力を必要としない。【選択図】 図２３
