A computer implemented method, comprising: detecting presence of an object of interest within a plurality of image frames received from a sensor; determining that the object of interest is moving towards an automatic door that is configured to close within a predetermined time period; determining, based on position, speed and direction of the object of interest, a likelihood that the object of interest may impede closing of the automatic door; and when the likelihood exceeds a threshold value, maintaining the automatic door in an open position for a longer period of time than the predetermined time period.

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.

Provided is a door engagement device including: a first member that extends in a vertical direction and is able to come into contact with an engaged part from a door closing direction side; a second member that extends in the vertical direction at a position with a distance from the first member to a door opening side and is able to come into contact with the engaged part from a door opening direction side; a pair of link members that form a parallel link mechanism in cooperation with the first member so as to enable the first member to pivotally move between a predetermined first position and a predetermined second position located closer to the door closing direction side than the first position while keeping the posture of the first member; and a restricting part that releasably restricts the pivotal movement of the first member at the first position.

An emergency brake device for occurrence of acceleration of an elevator door of the present inventive concept is fixedly installed at both lower ends of the elevator door and moves up along a guide rail, and may be configured comprising: a fixing bracket (110) secured to the elevator door; an acceleration prevention device (100) installed in a front inner side of the fixing bracket (110) and causing a braking force when a door downward speed of the elevator door accelerates above a regulation speed; a braking blade driving mechanism (150) which receives the braking force of the acceleration prevention device (100) and brings a braking blade (151) into contact with the guide rail (300), thereby stopping the door downward movement of the elevator door; and a braking force transmission system for transmitting the braking force between the acceleration prevention device (100) and the braking blade driving mechanism (150)

An elevator car door apparatus includes a door frame, a door motor, a motor pulley, a reduction pulley, a first driving pulley, a second driving pulley, a reduction belt, and a driving belt. The door motor, the reduction pulley, and the first driving pulley are supported on the door frame by means of a unit supporting member. The unit supporting member includes a flat plate portion that is placed on a frame vertical surface of the door frame. The reduction pulley and the first driving pulley are rotatable around a fixed shaft that is fixed so as to be perpendicular to the flat plate portion.

A zone object detection system including a passenger compartment. Also included is a door moveable between an opened position and a closed position. Further included is a first sensor monitoring a first zone outside of a plane of the door. Yet further included is a second sensor monitoring a second zone comprising at least one of the plane of the door and outside of the plane of the door. Also included is a controller in operative communication with the first sensor and the second sensor, the controller commanding a first modification of a door closing movement of the door if an object is detected in the first zone, the controller commanding a second modification of the door closing movement of the door if an object is detected in the second zone.

Methods and system for tuning automatic doors are provided. Aspects includes receiving, by a controller, a request to open an automatic door, the request inputted to a first interface at a first location, determining an initial transfer time allowance (TTA), the initial TTA comprising an initial duration of time between a door open request time and a door closing start time, wherein the initial TTA is based on the first location, operating, by the controller, the automatic door to open and remain open until an expiration of the initial TTA, determining an occurrence of a transfer, wherein the transfer occurs at a first time point, determining whether the transfer is associated with the request, storing, in a memory, the first time point, and determining an adjusted TTA based on the first time point for the at least one transfer, wherein the adjusted TTA is associated with the first interface.

The invention relates to an elevator landing door assembly and a method for installing an elevator landing door. The landing door assembly comprises at least a landing door unit to be assembled to a landing door base opening having an upper edge, two side edges and a lower edge, which landing door unit comprises at least a top track and one or more door panels suspended by the top track through one or more supporting elements, and a door sill. The assembly comprises fixing elements in the landing door base opening equipped with receiving parts for fastening the landing door unit.

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.
