Abstract
An elevator door panel for closing the opening to an elevator shaft comprising a generally planar steel sheet reinforced on the shaft side by a perimeter framework and intermediate vertical stiffening members. At its lower edge the panel includes a resilient seal member supported on a structural steel construction that is generally symmetrical about a vertical plane at a mid-section of the panel thickness.
Claims9
An elevator door panel for closing the opening to an elevator shaft at a landing in a building, the door panel having a generally planar steel sheet facing the landing, guides for restraining the door for movement in a vertical plane upwards from a closed position to an open position and downwards from the open position to the closed position, the door panel having a resilient astragal assembly on its lower edge, the lower edge of the door panel including a steel structural element lying in a horizontal plane and extending across substantially the full width of the door panel between vertical edges of the panel, the structural element forming the primary structural stiffening element of the door panel adjacent its lower edge, the structural element having a cross-section that is symmetrical about an imaginary vertical plane adjacent a mid-plane of the panel.
