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.

Elevator entrance sill structure and installation method

This invention relates to an improved sliding entrance door assembly for an elevator and to the method of installing the assembly. In one embodiment the assembly includes one or more stationary panels affixed to the frame. The stationary panels are comprised of a side panel and a transom panel. The side panel replaces the wall adjacent to the elevator opening. The transom panel is located above the sliding entry door and the side panel. By using the stationary panel, which is thinner than a conventional wall, the sliding entry door assembly uses less of the hallway space. In an alternate embodiment, two sliding entry doors are installed in the frame. They are in separate planes so that one door can slide behind the other. The advantages to the present door assembly is that it may be installed in less time and the assembly requires less space than conventional door assemblies. Also the assembly closes the gap to the shaftway as soon as it is installed.

Elevator entrance door assembly and method of installation

This invention relates to an improved sliding entrance door assembly for an elevator and to the method of installing the assembly. In one embodiment, the elevator sliding entrance door assembly comprises, viewed from the hallway, a sill, a left vertical post having a top portion, a right vertical post having a top portion and positioned parallel to the left post, a header formed with an open notch connected to the left and right posts, a door frame consisting of a strike jamb, head jamb and return jamb attached to the header, one post and sill. An elevator door track is attached to the header. The assembly also includes a sliding elevator door having rolling means to rollingly suspend the door from the track, the door being adjustable after being suspended through the opening formed in the header. In addition, the slide sill having a groove therein which defines a lower track for the door extends between the left post and the right post.
