Abstract

A platform stabilization coupler for transmitting acceleration forces to an elevator platform disposed on an elevator car frame is presented. The coupler includes a vibration member having a first surface disposed in fixed relation to either one of the elevator car frame and the platform. The coupler additionally includes a linear bearing disposed in fixed relation to a second surface of the vibration member. The bearing is disposed in moveable relation with the other of the elevator car frame and the platform to allow substantially vertical movement of the platform relative to the elevator car frame. The vibration member and linear bearing provide a transmission path for the lateral acceleration forces from the elevator car frame to the platform.
