An object sensing assembly for an elevator system. The object sensing assembly includes an elevator door moveable between an opened position and a closed position. Also included is a pressure sensor assembly located on a leading edge of the elevator door. The pressure sensor assembly includes a plurality of pressure sensors located at different height locations along the leading edge of the elevator door. The pressure sensor assembly also includes a controller in operative communication with the plurality of pressure sensors, the controller opening the elevator door if a pressure differential is detected between the plurality of pressure sensors.

A door control system is provided. Aspects includes a sensor having a field of view in proximity to a door threshold of an entrance to an occupancy area, wherein the sensor is adapted to detect objects in the door threshold and a landing area proximate to the door threshold, wherein the sensor is operated based on a movement of a door in the door threshold. And based at least upon detecting an object within a portion of the door threshold or the landing area, the sensor operable to signal a door operation controller to perform an action.

Sliding door systems are provided herein. The sliding door systems include a sliding door having a panel base, a sill having a guide channel having a stop arranged within the guide channel, wherein the guide channel includes a first subchannel and a second subchannel, wherein the first subchannel is defined at least partially by the stop and wherein the stop defines a gap connecting the first subchannel to the second subchannel, and an anti-derailment system. The anti-derailment system includes a first member having a first end and a second end, wherein the first end extends into the first subchannel and the second end connects to the panel base and a second member attached to the first member, wherein the second member is positioned within the second subchannel of the guide channel.

The invention relates to a method for condition monitoring of a rope of a hoisting apparatus, and to an arrangement for condition monitoring of a rope of a hoisting apparatus, preferably of an elevator for transporting passengers and/or goods. The arrangement for condition monitoring of a rope of a hoisting apparatus according to the present invention, in which rope comprises one or more conductive load bearing member for bearing the load exerted on the rope in longitudinal direction and extending parallel to each other and to the longitudinal direction of the rope, comprises an at least one eddy current testing probe, placed near said rope for generating an alternating magnetic field, said alternating magnetic field causing eddy currents in said rope, and for detecting a secondary magnetic field being generated by said eddy currents in said rope as eddy current detection data, and an on-line monitoring unit receiving and utilizing said eddy current detection data for on-line condition monitoring of said rope.

The present disclosure relates to a car door for a lift car having a guide mechanism and a door leaf. The guide mechanism comprises in this case a sliding shoe, which is connected to the door leaf of the car door. Furthermore, the guide mechanism comprises a receiving part which surrounds the sliding shoe on at least three sides. The sliding shoe has, in a sliding direction, an extent which corresponds to at least 30% of the extension of the door leaf in this direction.

A modular door drive control system for subjecting electrical drive motors to open-loop control and/or closed-loop control to open and close doors or door leaves in different applications includes at least one motor control unit, and a plurality of peripheral adaptation units for adapting the motor control unit or a plurality of the motor control units to match one of the different applications, where the motor control unit or a plurality of the motor control units are selectively connectable to each of the peripheral adaptation units to transmit electrical power for the drive motor, which is respectively connected to the motor control unit, via a common intermediate circuit such that door drive controllers for different applications can be realized with the aid of a modular door drive control system of this kind, without a relatively high level of expenditure on adaptation.

A guiding device for an elevator door leaf that includes a body within which at least a first cavity open outwards of said body. The guiding device also includes a first spherical element rotatably inserted in the first cavity and arranged so as to protrude from the first cavity outwards and anti-friction means interposed between the first spherical element and at least one wall delimiting the first cavity to limit the movement of the first spherical element within the first cavity.

A door system is provided and includes=a door assembly operable to assume an open position at which an aperture is opened and a closed position at which the aperture is closed, a sensor assembly and a controller. The controller is coupled to the door assembly and configured to instruct the door assembly to normally assume the closed position and to assume the open position in accordance with an open signal being issued by the sensor assembly. The sensor assembly is configured to track the individual, determine whether the individual is likely to be approaching the aperture from the tracking and issue the open signal in accordance with a determination that the individual is likely to be approaching the aperture.

An elevator door wedge monitoring system is provided. The elevator door wedge monitoring system comprising: an engagement sensing system configured to detect an engagement parameter, wherein the engagement parameter indicates whether an elevator door wedge is properly engaged with an elevator door; a communication device in electronic communication with the engagement sensing system and configured to receive the engagement parameter from the engagement sensing system; and an application installed on a user device in wireless communication with the communication device; wherein the communication device is configured to transmit the engagement parameter to the application.

In a roof arrangement for an elevator car in an elevator, the elevator car including an untreated roof, walls and a ceiling hinged to the untreated roof, the ceiling is hinged to the untreated roof of the elevator car with a hinge mechanism including an articulation mechanism that is arranged to pull the first end of the ceiling away from the wall of the elevator car at the same time as the second end of the ceiling is turned downwards.
