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. The elevator door sill assembly brackets are generally L-shaped with a vertical cleat extending therefrom toward the interior of the elevator shaft. The cleats have vertical slots formed therein. The elevator door sill assembly has off set clips that are mounted on the sill and are attached to the lower ends of a pair of elevator door vertical posts. The elevator door sill assembly has a pair of vertical elevator door supports on opposite sides of a pair of vertical elevator door posts which are adjustably attached to the brackets.
