Abstract
An elevator door sill assembly for use in elevator systems that have sliding doors. The door sill assembly comprises a sill plate, a support sill located below the sill plate having a rail that presents an inboard sliding surface and an outboard sliding surface. The assembly also comprises a first guiding surface that engages that inboard sliding surface and a second guiding surface that engages the outboard sliding surface. The assembly prevents that bottom of the elevator door from swinging while the door slides opened and closed. The sill assembly and guide system may be used with either hoistway doors or elevator car doors.
