摘要： An elevator car for an elevator installation may include at least one side wall having a doorway and an elevator car door. For opening and/or closing the doorway, the elevator car door can be moved at least partially parallel to the side wall on an outside of the side wall. In opening and/or closing, the elevator car door can be moved at least partially in a direction perpendicular to the side wall. In the closing process, the elevator car door can be at least partially sunk in the doorway. A coupling element may couple the elevator car door to a shaft door in at least one of opening or closing the elevator car door.

摘要： Provided is an elevator door device including: a rail that is disposed above an entrance; an opening and closing part of the entrance; and a locking mechanism that locks the opening and closing part. The locking mechanism includes: an engaging part including an engaging body that changes its position between a releasing position and an engaging position in association with the opening and closing of the opening and closing part; and an engaged part including an engaged body engaged with the engaging body at the engaging position. The engaged part is disposed in an area between the rail and the entrance, and overlaps with the rail as seen in plan view in the area. The opening and closing part has such a shape as to be able to open and close without abutting on the engaged part.

摘要： According to an aspect, an elevator sensor calibration system includes one or more sensors operable to monitor an elevator system, an elevator sensor calibration device, and a computing system. The computing system includes a memory and a processor that collects a plurality of baseline sensor data from the one or more sensors during movement of an elevator component, collects a plurality of disturbance data from the one or more sensors while the elevator component is displaced responsive to contact with the elevator sensor calibration device during movement of the elevator component, and performs analytics model calibration to calibrate a trained model based on one or more response changes between the baseline sensor data and the disturbance data.

摘要： An elevator system includes a car door and a sensor module. The car door is movable relative to an elevator car by a drive mechanism. The sensor module includes a first acoustic sensor arranged to provide a first acoustic signal, a second acoustic sensor arranged to provide a second acoustic signal, and a processor arranged to receive the first acoustic signal and the second acoustic signal. The processor is programmed to, responsive to an input provided to the first acoustic sensor and the second acoustic sensor, identify a direction of an elevator system noise source based on a first time delay based on the first acoustic signal and the second acoustic signal.

摘要： A sill (1, 1′) for a lift door is manufactured with a method that includes the steps of providing at least one support element (2) and an upper profile (4) that defines at least a boundary surface (6) of a first groove longitudinal (8) for slidingly receiving a lift door. The support element (2) and the upper profile (4) are joined, placing a first demarcation profile (10, 10′) alongside the upper profile (4), so that a boundary surface (12) of the first demarcation profile delimits part of the first longitudinal groove (8). A sliding transversal cross-section of the first longitudinal groove (8) is adjusted by approaching/distancing the boundary surfaces (6, 12) and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (10, 10′) and of the upper profile (4).

摘要： An elevator includes a car with at least two car doors, each car door being provided with a door contact, a shaft being provided with corresponding landing doors, each landing door being provided with a door contact, each landing door opening in synchronism with the corresponding car door, the door contacts forming part of a safety circuit of the elevator, a car door contact input being connected to a middle point in the safety circuit between a series connection of the car door contacts and a series connection of the landing door contacts. A status information of the car door contact input is monitored in order to determine whether the door contacts are operational or not when the car doors are opened and/or closed with a predetermined time delay at a landing.

摘要： An elevator door stopping device which can prevent that elevator door is closed by itself when power supplied to a motor for opening and closing the elevator door is interrupted, an improvement of the elevator door stopping device characterized in that a first magnetic body is fixed on a shaft rotating in interlock with opening and closing of the elevator door so as to generate a magnetic force in a radial direction perpendicular to the shaft, and a second magnetic body is fixed on a fixed face spaced apart from the first magnetic body at a predetermined interval in the radial direction in such a manner that the second magnetic body has the opposite pole to the first magnetic body, so that a magnetic force is generated between the first magnetic body and the second magnetic body in the radial direction perpendicular to the shaft.

摘要： In an elevator car door apparatus, a locking member is disposed on a blade-carrying car door, and is displaceable between an unlocked position and a locked position interdependently with movement of a doorstop-side blade. A guiding portion is disposed on the locking member. A guiding cam is disposed outside the blade-carrying car door. When the car is positioned outside an appropriate floor alignment position, the blade-carrying car door moves in an opening direction, the guiding portion moves along the guiding cam, the locking member displaces to the locked position, and the doorstop-side blade also displaces to a locking accommodating position, the locking member catches in a fixed latch, and movement of the blade-carrying car door in the opening direction is prevented.
