发明名称 Method and apparatus for fastening a door panel to a door operator mounted on an elevator car
摘要 An elevator system including an elevator car, an elevator door, and a door operator for operating the door to open and close an entranceway to the car. The door has integral hanger brackets which are fastened to a hanger plate associated with the door operator. The door may be easily mounted, oriented and aligned in the field by a fastening arrangement and method which includes clamping bolts and jacking bolts. The clamping bolts are adjusted to initially support the weight of the door. Jacking bolts are then coupled between the hanger bracket and hanger plate, and the jacking bolts are actuated to align the door and set the sill gap. The clamping bolts are then tightened to maintain the selected alignment and sill gap. The clamping bolts, jacking bolts and the frictional area contact between the clamped surfaces all co-operate to support the weight of the door, and the clamped surfaces additionally function to add structural stiffness to the door and its support.
