摘要： A stair-climbing system includes a guide rail laid along stairs, a chair slidably mounted on the rail, and a lifter for moving the chair along the rail. The chair is provided with a switch for activating the lifter, and a sensor for detecting that a person is sitting on the chair and keeping the switch inoperative while a person is not sitting on the chair. The system further includes at least one lamp having a sensor adapted to turn on the lamp only while a person is near the lamp. The system further includes a chair stop mechanism having a speed sensor for detecting the speed of the chair, a brake mounted on the lifter for braking the lifter, and a control unit for deactivating the lifter and activating the brake if the speed of the chair, detected by the sensor, exceeds a predetermined value.

摘要： In a chair type stair elevating device in which upper and lower rails and a rack or chain parallel to the rails are provided along the stairs, an elevating mechanism mounted on the rails is moved by a pinion or sprocket of a driving machine meshing with the rack or chain. A chair is mounted on the elevating mechanism, and the rack or chain is received in the rail in a hidden state. In this way, the rack or chain is invisible, so that the design value of the entire device improves, and it is also possible to prevent injury and soiling of clothes by the rack or chain.
