REDUCTION GEAR AUTOMATICALLY RELEASING RESISTANCE
PROBLEM TO BE SOLVED: To provide a door that is gently and fully closed by comprising not a door closer with a high-pressure container but small resistance means, and provide a reduction gear that does not damage a dwelling environment and that can be miniaturized.SOLUTION: A device for decelerating a door is operated by a spring different from a spring for urging the door. Even when a weak spring is adopted, either the device for decelerating the door or a device for urging the door is operated, and the door is necessarily put into a fully closed state without being kept in a stopped state even in the case where the door is stopped midway through a closing operation. Resistance acting on the door is automatically removed after deceleration, and the spring decelerating the door is restored to inhibit rotation in a door opening direction.
【課題】高圧容器を備えるドアクローザではなく、小さな抵抗手段を備えて静かに全閉するドアを提供し、住環境を損なわない小型化可能な減速装置を提供する。【解決手段】ドアを減速する装置は、ドアを付勢するバネと別のバネで動き、弱いバネを採用しても、ドアを減速する装置とドアを付勢する装置の何れかは動いて、ドアが途中で止まっても止まったままにならずに必ず全閉する。ドアに作用した抵抗は減速後に自動的に取り除かれ、ドアを減速したバネが復元して、ドアを開く方向に回転させない。【選択図】 図２５
