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.

Elevator positioning clip system and method

An elevator positioning system includes an optical tape, optical tape clips, and a sensor. The optical tape clips are resiliently biased and mount to various structures including mounting bracket that attach to elevator guide rails or other framework within the hoistway. A connecting member of the optical tape clips is configured to be disposed between a sensor and optical tape such that the sensor detects an interruption in the optical tape and can send signals to an elevator controller in response to detecting these interruptions. The position of the optical tape clips is such that the elevator car can be controlled to align evenly with the landings associated with the hoistway.

Elevator positioning system and method

An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.
