Module for retrofitting and expanding existing pictogram-based elevator emergency call systems with a visual and multilingual graphic display

Abstract

Two-sense elevator emergency call module for visual two-sense emergency calls, characterized in that the module is designed in form factor and mounting such that it can be inserted into existing cutout dimensions of typical elevator emergency call panels and mounted behind existing panels without interfering with the cabin structure, regardless of the respective elevator manufacturer, existing pictogram-based modules can be replaced and combined with an integrated two-sense emergency call device in a standard-compliant all-in-one solution.

Description

[0001] The present invention relates to a visual elevator emergency call display which, independent of the elevator manufacturer, can be installed in an all-in-one solution with an integrated combined two-sense emergency call device, in compliance with standards, and with precise dimensions into an existing cutout for pictogram-based modules. The technical connection corresponds to the technology already installed in the elevator. Finally, elevators can be easily and quickly retrofitted in accordance with standards without increased installation effort.

[0002] Common elevator emergency call systems often rely on purely acoustic or simple pictogram-based status indicators. While systems with additional visual communication exist as entirely new solutions, there is no standardized way to retrofit existing, purely pictogram-based devices.

[0003] Existing solutions offer graphic or multilingual elements, but lack a modular, mechanically compatible and electrically adaptable unit specifically designed for retrofitting existing cutout dimensions.

[0004] The market already offers systems that rely on external communication via an app. This requires that the individuals concerned have a mobile device and that a corresponding mobile network is available.

[0005] Since the beginning of 2021, elevators in publicly accessible buildings have been required to have a two-sense emergency call system. In practice, however, it has become apparent that most of the emergency call solutions currently in use are limited to acoustic communication with the outside world.

[0006] There is a need for a device that complies with the standards of the two-sense emergency call system but transmits additional information, such as multilingual text messages, to reassure the trapped person, and fits precisely into existing installations, thus reducing installation effort.

[0007] The problem is solved according to the invention by a retrofit module that can be installed on existing pictogram-based elevator emergency call devices and provides a visual, graphic and multilingual display to show the emergency call status, without having to replace the existing emergency call device or extensively modify the installation.

[0008] The core idea of ​​the invention is the special development for retrofitting and, thanks to the precisely fitting design, can be integrated directly into existing cutout dimensions without requiring structural changes to cabin panels or front panels.

[0009] The module meets the requirements of EN81-70 for visual communication according to the two-sense principle and thus enables safe interaction for persons with hearing, speech or speech comprehension impairments according to the invention.

[0010] The display according to the invention, which is installed in the module, can display the different information with viewing angle stability for a consistent and high-quality image from different viewing angles.

[0011] The device is equipped with vandal-resistant features and has a protection rating of at least IP54. The display has a high impact resistance of at least IK06.

[0012] The invention features a function for people with hearing and speech impairments, enabling trapped individuals to be reassured about the further course of the emergency call visually via an LED display and additionally in multilingual text form. This combination of visual and textual information thus helps to calm the affected individuals.

Claims
