Embodiment Construction

[0014] figure 1 Selected portions of an elevator system 20 are shown, including an elevator car 22 movable along car guide rails 24 . A counterweight 26 is associated with the elevator car 22 by a roping arrangement (not shown), and moves along a counterweight guide rail 28 in conjunction with the movement of the elevator car 22 . One of the car guide rails 24 and the two counterweight guide rails 28 are on one lateral side of the elevator car 22 (ie, not the front side including the doors or the opposite facing rear side). A plurality of brackets 30 secure those rails in their desired positions.

[0015] If according to figure 2 As can be appreciated, the elevator car 22 and counterweight 26 are movable within an elevator hoistway 32 having a front wall 34 (ie, the wall including the doors), a rear wall 36 , and side walls 38 . The bracket 30 is secured to a side wall 38 at the lateral side of the elevator car selected for positioning the counterweight 26 . If according ...

Abstract

An exemplary door frame assembly that is useful in an elevator system includes a plurality of door frame members including a header, a sill and a plurality of jambs. The door frame members are configured to be secured into a desired position along a hoistway. At least one guide rail bracket is supported by at least one of the door frame members. The guide rail bracket is moveable relative to the door frame member between a handling position in which the guide rail bracket is generally parallel to at least one of the header or the sill and a deployed position in which the guide rail bracket is generally perpendicular to the at least one of the header or sill.

Description

Background technique [0001] Elevator systems are well known and widely used. There are various configurations of elevator systems. In many cases, the elevator car is associated with a counterweight, and the two move in a coordinated manner within the elevator hoistway. As the elevator car and counterweight move within the elevator shaft, they each follow the guide rails. [0002] Installing guide rails in elevator systems presents challenges and difficulties. The rail installation process is often time-consuming and labor-intensive. There are typically a number of bracket members used to secure the guide rails in the desired position within the elevator hoistway. Additionally, alignment of the guide rails throughout the elevator hoistway must be ensured to achieve proper ride quality. [0003] For example, current track fixings are adjustable for all tracks. There are as many necessary alignment measures as there are tracks. This is usually done by lowering individual w...
