Abstract: An elevator entrance sill assembly and method of installing and leveling of an elevator sill are provided. An elevator entrance sill assembly is provided for mounting at the elevator entrance adjacent to the elevator shaft. The sill is mounted to a support assembly which provides the necessary stiffness to prevent the sill from flexing. Hinge supports are attached to the sill assembly and mounted on the building floor adjacent to the elevator shaft and rotatable to extend upwardly from the floor and out of the elevator shaft. The door sill assembly is attachable to the hinge support while in the upward or vertical position out of the elevator shaft. The hinge support and the sill assembly are rotatable downwardly to a horizontal position on the floor after attachment of the sill assembly to the hinge support with the sill assembly extending into the elevator shaft.

Abstract: The invention relates to a highly advantageous, novel and cost saving way of solving a difficult and expensive problem in the structure and installation and leveling of an elevator sill. The assembly structure and installation is one of simplicity and ease of installing from the hallway. The elevator door sill assembly is installable from a hallway without the use of a moving elevator platform. An elevator door sill is provided for mounting at the elevator entrance adjacent to the elevator shaft. The sill is mounted to a support assembly which provides the necessary stiffness to prevent the sill from flexing. Hinge supports are attached to the sill assembly and mounted on the building floor adjacent to the elevator shaft and rotatable to extend upwardly from the floor and out of the elevator shaft. The door sill assembly is attachable to the hinge support while in the upward or vertical position out of the elevator shaft.
