Abstract

An elevator car system and a method of operating an elevator door of an elevator car include an elevator car configured to travel between and stop on a plurality of floors, the elevator car having a door capable of opening and closing along a pathway, a first obstruction sensor disposed on or within the door configured to detect a first obstruction in the pathway, a supplemental obstruction sensor located on a floor of the plurality of floors, and located external to both the elevator car and the door, the supplemental obstruction sensor configured to detect a second obstruction, and wherein closing of the door is prevented or modified based on at least one of: the first obstruction sensor having detected the first obstruction, and the supplemental obstruction sensor having detected the second obstruction on the floor external to the elevator car and the door when the elevator car is substantially stopped and located on the floor.

IPC Classes  ?

• B66B 13/14 - Control systems or devices
• B66B 13/26 - Safety devices in passenger lifts, not otherwise provided for, for preventing trapping of passengers between closing doors

Abstract

An elevator car system and method for operating elevators doors includes an elevator car having a door capable of opening and closing along a pathway and an interior portion internal to the door, a first obstruction sensor disposed on the door capable of detecting an obstruction in the pathway of the door, and a supplemental obstruction sensor disposed in the interior portion of the elevator car system capable of detecting an obstruction in an area adjacent to the door, wherein the door opens or closes based on the detection of the first obstruction sensor or the detection of the second obstruction sensor. The interior portion of the elevator car may include a recessed channel, with the supplemental obstruction sensor being disposed in the recessed channel.
