Abstract:
A system for detecting the presence of an object in a doorway having a powered door is disclosed, the system comprising: a radiation transmitter (202) adapted to direct radiation substantially along a longitudinal edge of the doorway in a direction substantially perpendicular to a direction of motion of said powered door; a radiation receiver (204) for receiving the radiation transmitted by the radiation transmitter; a processor configured to detect interruption of said radiation by an object whereby to detect the presence of an object in the doorway.

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.
Abstract:
An obstacle-detecting apparatus for a powered door or a frame of the door includes a circuit board, a surface-mount element for emitting or receiving radiation, and a radiation re-directing device. The surface-mount element and radiation re-directing device are both mounted on the circuit board, the radiation re-directing device being at a defined position relative to the surface-mount element. The re-directing device includes a reflecting member, mounted to sit at a defined angle relative to radiation emitted from or received by the surface-mount element, for re-directing the radiation. The re-directing device also includes a moulded-plastic frame member on which the reflecting member sits and which is used to position the reflecting member relative to the surface- mount element. The reflecting member abuts a surface-mount emitter diode that emits radiation. The same re-directing device may be used with a receiving diode, but then the reflecting member is positioned on the circuit board to sit further from the diode; in that case, an end wall of the frame member is used for setting an appropriate distance between the re-directing device and the receiving diode. The re-directing device might alternatively be a prism. An obstacle-detecting apparatus with an emitter diode or diodes forms, together with an obstacle-detecting apparatus with a receiving diode or diodes, a system for detecting an obstacle in front of or between the powered doors. That system works in association with a visible-light display system to inform persons approaching an elevator car whether it is possible to safely enter the car.
Abstract:
An edge device for an elevator door includes an elongate array of infrared transmitters and/or receivers and a proximate elongate array of illuminable elements, both arrays extending for a substantial part of the length of the door. The illuminable elements are adapted to be illuminated when the door is in motion. The two arrays are disposed in a common carrier structure, being either vertically interleaved or extending vertically in parallel with each other.
Abstract:
The elevator device which comprises a safety shoe projecting from the front edge of an elevator door and having a function by which upon retraction either door closure is prevented or door opening is effected, a means for retracting the safety shoe in the vicinity of the full door opening position, and a means for canceling the function of the safety shoe in the vicinity of the full opening position of the door. This is intended to positively cancel the function of the safety shoe in the vicinity of the full door opening position. Therefore, without providing a complicated mechanism for displacing the position of a switch for detecting the retraction of the safety shoe, retraction of the safety shoe in the vicinity of the full door opening position is made possible, in the door closable position, simply by using the nullification means (the means for canceling the function of the safety shoe).
Abstract:
A safety system for detecting small objects that approach closing doors comprising a transmitter stack, a detector stack, and a controller including instructions to detect small objects as the doors are closing. A transmitter or a group of transmitters from the transmitter stack are powered sequentially resulting in an output from the detector stack. The controller compares each output from the detector stack with an average of all the outputs plus a threshold value. The outputs that exceed the average plus threshold value trigger the safety system to reverse closing operation of the doors.
