A synchronizing assembly for elevator door configured to synchronously open and close a first door and a second door from the center of an elevator in responsive to the movement of a belt in a first direction and a second direction. The synchronizing assembly includes a first link extending from a first end to a second end and configured to pivot about a first pivot between the first end and the second end, the first pivot being mounted on the first door, the first end of the first link being pivotally attached to the belt; a second link pivoting about a second pivot mounted on the first door and configured to fix the first link when the second pivot is engaging with the second end of the first link; and a force applying member configured to provide the first link with a force.

A linkage device used between an elevator car door and a hall door, and an elevator system. The linkage device includes: a link mechanism; a first door vane and a second door vane that are connected to the link mechanism; and an actuating mechanism for actuating the link mechanism so that the first door vane and the second door vane are switched between a contracted position and an expanded position; wherein the link mechanism includes: a first link and a second link arranged in parallel, each of which includes a link body and a slider; the link body of the first link and the link body of the second link are pivotally connected to the car door, and the slider of the first link and the slider of the second link are each capable of sliding along a passage defined by the corresponding link body.

An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.

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.
