Elevator rail mounting bracket

An elevator rail mounting system for positioning a pair of elevator guide rails, capable of centering an elevator therebetween, in a hoistway, having a pair of side walls and an entrance side defined by a landing sill and a hall door frame, comprising a U-shaped bracket capable of being mounted in the hoistway from the entrance side thereof, said U-shaped bracket including a cross member mounted from the entrance side of the hoistway and substantially adjacent and parallel thereto, said cross member having mounting means for fixedly supporting the landing sill and hall door frame in relation to the guide rails, whereby the angular relationships of and distances between the guide rails, the landing sill and the hall door frame are fixed to insure a constant running clearance between the elevator and the landing sill and to maintain the proper alignment of the elevator and the hall door frame, a pair of parallel rail brackets, spaced apart by a predetermined distance and extending into the hoistway perpendicularly from said cross member, for supporting the guide rails in a vertical plane substantially parallel to the entrance side of the hoistway and maintaining the distance between the guide rails at a predetermined fixed value independent of the side walls of the hoistway, whereby only a single supporting wall for the guide rails is utilized.
