Abstract: Disclosed is an elevator having covers capable of minimizing a generation of turbulent flows at upper and lower portions of the elevator cabin so as to reduce noise and vibration during the operation of the elevator. The elevator according to the present invention comprises upper and lower horizontal supporting members made of shaped steels having a L shape in cross section and plate strips, and covers having a dome and a truncated pyramid shape. In the elevator according to the present invention, the covers can temper impacts, due to air flows in a hoistway, against the elevator cabin during the operation of the elevator. As a result, noise and vibration due to the impacts can be reduced.

Abstract: A guide roller supporting apparatus for an elevator car includes a guide roller supporting apparatus comprising guide rollers making contact with surfaces of a guide rail, respectively, each guide roller being rotatably mounted on an upper end of a carrying member, a lower end of the carrying member being pivotably mounted on a frame secured to a top or a bottom plate of an elevator car; a spring mechanism resiliently urging the guide roller against the corresponding surfaces of the guide rail to absorb a lateral force of an impact transferred through the guide roller; and a support secured to the frame and having a spring seat, whereby the vertical force supports the carrying member, an external impact through the guide rollers is divided into vertical and lateral forces, and the lateral force is absorbed to decrease a shaking of the elevator car.
