Abstract: The invention refers to an elevator door leaf comprising a door panel and a support structure having at least one profile. The door leaf comprises a vertically extending expansion member which is fixed to the door leaf only at one vertical level, whereby the expansion member consists of a material having a larger thermal expansion coefficient than the material of the door panel and/or of said profile.

Abstract: The invention relates to an elevator car comprising a support frame, a floor structure and a ceiling structure, as well as at least one car door, and side walls extending between the floor structure and the ceiling structure, wherein the side walls are formed from several wall elements, which are aligned end-to-end or end-to side in corners, wherein the wall elements are composite panels consisting of at least one support material and at least one noise insulating material, that the elevator car comprises at least one flatbar, extending over the surface of both adjacent wall elements, and covering the joint between them, which flatbar comprises or is connectable with fixing elements to at least one of both adjacent wall elements. Via this means the joint between two noise insulating wall elements does prevent any essential noise leakage.

Abstract: The elevator door panel is formed of a composite material based on reinforcement fibres embedded in a polymer matrix material, the reinforcement fibres being arranged in the polymer matrix material so that the elevator door panel is stiff in a vertical plane, but can be bent to a curve around a vertical corner.

Abstract: According to an aspect, there is provided a method for controlling an elevator system. The method comprises causing transmission of radio frequency signals with at least one radio frequency sensor attached to at least one element movable in an elevator shaft of an elevator system, receiving, from the at least one radio frequency sensor measurement data representing radio frequency signals reflected from at least one object and captured with the at least one radio frequency sensor, causing identification, based on the measurement data, of at least one object; and controlling operation of the elevator system in response to identifying the at least one object based on the measurement data.

Abstract: A method and a system for enhancing elevator positioning includes a camera system designed to record pictures and a computer system designed to determine an absolute distance or a distance between two elements of the recorded pictures. The device is designed to determine the relative distance between the floor of an elevator car and the floor of a landing.

Abstract: A method for generating maintenance data of an elevator door system includes detecting a first event during closing or opening of a door of the elevator door system and defining a time stamp of the first event, wherein the first event is opening or dosing of a safety circuit; detecting at least one second event during said closing or opening of the door of the elevator door system and defining time stamp of the at least one second event; defining a difference value by comparing the time stamp of the first event and the time stamp of the at least one second event; comparing the difference value to previously stored one or more difference values; and generating maintenance data of the elevator door system. A system is provided to perform at least partly the method.

Abstract: The invention refers to an elevator door leaf comprising a door panel and a support structure having at least one profile. The door leaf comprises a vertically extending expansion member which is fixed to the door leaf only at one vertical level, whereby the expansion member consists of a material having a larger thermal expansion coefficient than the material of the door panel and/or of said profile.

Abstract: A platform assembly includes a first platform module having an elongated front face, a second platform module having an elongated front face, and a locking member for locking the front faces of the first and second platform modules to each other. The locking member is movably mounted on the first platform module in a longitudinal direction of the front face thereof, and at least one of the locking member and the second platform includes a locking protrusion, and the other of the locking member and the second platform includes a locking slot, wherein the locking protrusion is received by the locking slot and protrudes from the front face of the first platform module. An edge of the locking protrusion is behind an edge of the locking slot when the locking member is moved in said longitudinal direction of the front face, thereby locking the platform modules to each other.
