Abstract
The sliding door assembly for an elevator and a method for replacing an existing swinging elevator door with a sliding elevator door. The swinging door assembly is removed and is replaced in situ with a sliding elevator door assembly. A portion of the wall adjacent to the elevator door is removed, permitting the sliding door to slide into the part of the wall which has been removed. The part of the wall which has been removed and in which the sliding door fits is covered by a stationary panel. In another embodiment, there are two sliding doors that slide behind the side stationary panel. A left sliding entrance door and a right sliding entrance door are in separate planes so that one of the doors can slide behind the other.
