DEVICE FOR REDUCING WIND NOISE OF ELEVATOR CAR TO BE MOVED AT HIGH SPEED

摘要

PROBLEM TO BE SOLVED: To provide a device composed of aerodynamic elements attachable to the outside and a device accessible to the roof of the elevator car, and for reducing wind noise and vibration of the elevator car to be moved at a high speed. SOLUTION: An upper part 3 having an oval-like shape and attached from the outside is movably placed on an elevator car 1 and directly held by a mechanical method by a centering device. Recesses on the side surface surround guide roller supports 6. As a method for providing access to the roof of the car 1, an integrated lifting device capable of lifting the upper extension element 3 is provided. A lower extension element 4 is constituted into a frame-shaped hollow body and has a flap on the lower side, and the flap can be downwardly turned to enable access to a device on the lower side of the elevator car 1.
