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.
Claims16
An elevator car system, comprising:
- 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 adjacent to the door in the interior portion of the elevator car system capable of detecting an obstruction in an area adjacent to the door in the interior portion of the elevator car;
- wherein the door opens or closes based on the detection of the first obstruction sensor or the detection of the supplemental obstruction sensor.
An elevator door obstruction sensor apparatus, comprising:
- a channel disposed adjacent to a door within an elevator car having an interior portion internal to the door, the door capable of opening and closing;
- and
- an obstruction sensor disposed in the channel capable of detecting an Obstruction in an area adjacent to the door in the interior portion;
- wherein the door opens or closes based on the detection of the obstruction sensor.
A method of operation for all elevator door, comprising:
- (a) receiving an instruction to close the door;
- (b) determining if a first obstruction sensor senses an obstruction;
- (c) determining if a supplemental obstruction disposed adjacent to the door sensor senses an obstruction in an interior portion of the door;
- and
- (d) closing the door if neither the first obstruction sensor nor the supplemental obstruction sensor senses an obstruction.
