  • Patent number: 7788854
    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.

  • Patent number: 6938380
    Abstract: This invention relates to a cost saving way of solving a difficult problem in the structure and installation and leveling of an elevator sill. This invention provides ease of installing from the hallway without the use of a moving elevator platform. The structure consists of a sill, a cradle for the sill and a pair of end brackets for supporting the cradle. The pair of spaced L-shaped end brackets are provided for attachment to the hall floor. A vertically adjustable sill cradle is supported at its end portions by the brackets and a horizontally and vertically adjustable sill is mounted on the sill cradle. The elevator door sill cradle is adjustable vertically by means of fasteners that are moveable in vertical slots in the end brackets and is horizontally adjustable on the cradle by means of fasteners that are moveable in horizontal slots provided in the cradle.
