An elevator car roof includes two toe boards for mounting the elevator car roof at a mounting position to uprights of an elevator car. Each of the toe boards has projecting brackets for holding the elevator car roof at the uprights in the mounting position. Each of the uprights includes a slot for receiving one of the projecting brackets when the elevator car roof is held in the mounting position by the uprights. The projecting brackets and the slots can be formed to prevent a wrong orientation of the elevator car roof relative to the uprights.

An elevator car for transporting people and goods and having a floor panel, at least three side panels, and a roof panel together forming a door opening. The floor panel, at least one side panel, and the roof panel are unitarily formed of a thermoplastic synthetic resin. A force-spreading element substantially more rigid than the panels is fixed in or on an face of one of the side panels or the roof panel. A hoist system for the car is fixed by fasteners to the load-spreading element.

A heavy load elevator installation platform capable of stretching and retracting steplessly, which includes an upper beam assembly and a lower beam assembly that can realize stepless stretching and retracting. The upper beam assembly includes an upper beam left C steel, upper beam middle C steel, and upper beam right C steel connected end to end in sequence. A plurality of long holes formed at an inclined included angle with the horizontal are formed in the inner side walls of each of the upper beam left C steel and the upper beam right C steel. A plurality of long holes are respectively formed in the two side surfaces, facing the upper beam left C steel and the upper beam right C steel, of the upper beam middle C steel. The structure of the lower beam assembly is the same as that of the upper beam assembly.

An audio system for an elevator includes two or more speaker cabinets arranged inside a suspended ceiling fixed to a ceiling board of a car of the elevator, an input device to which sound content radiated to an inside of the car from each of the two or more speaker cabinets are input, and a sound field control device configured to conduct phase control and reverberation time control for the sound content and thereby cause a sound wave based on the sound content to be radiated from the speaker cabinet to the inside of the car. Each of the speaker cabinets includes a casing arranged inside the suspended ceiling, and a speaker unit arranged inside the casing and having a radiation surface that radiates the sound wave.

The invention refers to an elevator system having a plurality of elevator cars, which elevator cars comprise several first cars and at least one second car, which second car differs from the first cars in its size and/or technical configuration, whereby the first cars and the second car run together within one and the same elevator shaft, which elevator system comprises an elevator control comprising a call allocation control having a first part connected to at least one call input device for allocating the first elevator cars and a second part connected to at least one call issuing means for the call allocation of the second car, whereby the first and second part of the call allocation control are configured to work independently of each other.

Elevator maintenance space projection systems and elevator systems including a projector located within an elevator shaft and arranged to project a display space within the elevator shaft such that the display space includes one or more projected images identifying at least one of a safety volume, a refuge space, and a maintenance location.

Elevator systems including an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side and a structural sound-generation system. The structural sound-generation system having at least one audio actuator coupled to the second side of the first elevator car component and an audio system controller in communication with the at least one audio actuator. The structural sound-generation system is configured to generate vibrations within the first elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car.

An interface for operating an elevator car includes an interface controller, a foil attached to a wall surface of a wall of the elevator car, the wall surface facing an inside of the elevator car, and at least one pressure-sensitive sensor configured for receiving user requests by an application of a pressure to the at least one sensor. The at least one sensor is connected to the interface controller, the interface controller transmitting the user requests received by the at least one sensor to a car controller of the elevator car, and wherein the at least one sensor is embedded in the foil.

An access door assembly for an elevator car, the access door assembly including: an elevator car panel including an access hatch; an access door panel arranged to close the access hatch; and a hinge mechanism connecting the access door panel to the elevator car panel; the hinge mechanism allows the access door panel to move from an initial closed position in an initial plane to a final open position in a final plane substantially parallel to the initial plane; wherein the initial plane is the plane of the elevator car panel; and the hinge mechanism constrains the access door panel when opening to move perpendicular to the initial plane of the elevator car panel and to rotate around an axis perpendicular to the initial plane of the elevator car panel, to enable the access door panel to reach a final open position.

The elevator comprises guide rails extending along a height of a shaft, a car and/or a counterweight moving upwards and downwards in the shaft and being glidingly supported on the guide rails. A stop block is attached to at least one guide rail in order to prevent movement of the car and/or the counterweight beyond the level of the stop block. The stop block comprises a buffer attached to a bottom plate. The buffer comprises a slot receiving a guide portion of the guide rail. The bottom plate supports the buffer on the guide rail.
