Elevator positioning clip system and method

摘要

An elevator positioning system includes an optical tape, optical tape clips, and a sensor. The optical tape clips are mountable to various structures within the hoistway. A crossbar of the optical tape clips is located between a sensor and optical tape such that the sensor detects an interruption in the optical tape and signals the detection to an elevator controller. The elevator car can then be controlled to align evenly with the landings associated with the hoistway. Another elevator positioning system includes a sensor and a reflector clip assembly. The reflector clip assemblies are mountable to various structures within the hoistway. A reflector target of the reflector clip assemblies faces the sensor such that the sensor detects the reflector target and signals the detection to an elevator controller. The elevator car can then be controlled to align evenly with the landings associated with the hoistway.

主权项

1. An elevator positioning system for aligning an elevator car with one or more landings, wherein the elevator car is operable to travel within a hoistway to the one or more landings, wherein the elevator positioning system comprises:
a. a sensor configured to attach to a portion of the elevator car; b. a detectable member, wherein the detectable member is detectable by the sensor; c. at least one positioning member, wherein the positioning member is attachable to a select one of a portion of the hoistway and an elevator guide rail, wherein the positioning member is positionable so that the sensor can detect a select one of the presence of the detectable member and the absence of the detectable member, and wherein the sensor signals the detection to an elevator controller of the elevator positioning system to control position of the elevator car within the hoistway relative to the one or more landings; and d. one or more alignment targets configured to provide the positioning system with fine vertical adjustment for the position of the elevator car relative to the one or more landings.
