Device for displaying images for stands or stairways
A device for displaying images for stands or stairways in a public venue includes a controller and a set of electronic screens connected to one another. Mounting devices secure the electronic screens to the risers of an existing stairway or stand. The controller controls displaying an advertising motif distributed between all the electronic screens.
1 . A device for displaying images for stands or stairways in a public venue comprising:
a central controller;
a plurality of electronic screen assemblies serially connected to one another, wherein each screen assembly has a thickness of less than 50 mm and is sealed having an IP protection rating between IP54 and IP68 and an IK protection rating between IK03 and IK10 and comprises a transparent element connected to a vertical face of the stand or stairway and a light-emitting electronic element which is positioned between the stand or stairway and the transparent element, wherein the transparent element comprises one or more of UV protection or a light-diffusing finish; and
means for securing one of said electronic screen assemblies to a corresponding riser of a stairway or stand, each of the screen assemblies are secured to the risers of the stand or stairway; the central controller having means for displaying an advertising motif distributed between all of said electronic screen assemblies, and the central controller comprising instructions for displaying information on each screen on status of nearby seats and/or entry/exit instructions to/from said seats or other safety information, and instructions for displaying information on each screen on status of nearby seats and/or entry/exit instructions to/from said seats or other safety information;
a plurality of separate control boxes connected to the central controller and serially connected to one another, wherein each of the plurality of control boxes is connected directly to one of the plurality of screen assemblies corresponding to a step, wherein each of the control boxes is separate and mounted apart from the screen assemblies and configured to be installed and positioned beneath seats attached to the stand or stairway, or hidden behind the stairway, wherein an upper portion of the screen is flush with an adjacent tread and an upper surface of the upper portion of the screen has a non-slip finish, forming an extension of the adjacent tread so the device leaves treads of the stand or stairway free;
wherein the plurality of screen assemblies are connected serially by multicables comprising a power cable and a data cable, wherein signal processing elements, data elements, and power supply elements are associated with each emitting element and are housed in a respective control box, and said signal processing and data elements comprising two power sources (PSU) or voltage transformers arranged redundantly, and two image reception cards arranged redundantly in the control box, wherein the two power sources and the two image reception cards are removably and interchangeably housed in the control box;
wherein the separate boxes control one or more of the following:
brightness,
contrast,
image refresh rate,
grey scale,
clock rate;
wherein mechanical and weather resistance requirements for the plurality of control boxes are reduced compared with mechanical and weather resistance requirements for the screen assemblies.
2 . The device according to claim 1 , wherein the transparent element is screwed to the stairway or stand.
3 . The device according to claim 1 , comprising a communication post configured to interrupt emission of advertising content, and to change to evacuation information mode in an emergency.
4 . The device according to claim 3 , wherein each of the plurality of control boxes comprises a memory storing evacuation signals.
5 . A device for displaying images for stands or stairways in a public venue comprising:
a central controller;
a plurality of electronic screen assemblies serially connected to one another, wherein each screen assembly has a thickness of less than 50 mm and is sealed having an IP protection rating between IP54 and IP68 and an IK protection rating between IK03 and IK10 and comprises a transparent element connected to a vertical face of the stand or stairway and a light-emitting electronic element which is positioned between the stand or stairway and the transparent element, wherein the transparent element comprises one or more of UV protection or a light-diffusing finish; and
means for securing one of said electronic screen assemblies to a corresponding riser of a stairway or stand, each of the screen assemblies are secured to the risers of the stand or stairway; the central controller having means for displaying an advertising motif distributed between all of said electronic screen assemblies, and the central controller comprising instructions for displaying information on each screen on status of nearby seats and/or entry/exit instructions to/from said seats or other safety information, and instructions for displaying information on each screen on status of nearby seats and/or entry/exit instructions to/from said seats or other safety information;
a plurality of separate control boxes connected to the central controller and serially connected to one another, wherein each of the plurality of control boxes is connected directly to one of the plurality of screen assemblies corresponding to a step, wherein each of the control boxes is separate and mounted apart from the screen assemblies and configured to be installed and positioned beneath seats attached to the stand or stairway, or hidden behind the stairway, wherein the stand or stairway includes a step comprising a projecting ledge on a tread of each step, wherein one of the electronic screen assemblies is positioned beneath the projecting ledge so the device leaves treads of the stand or stairway free;
wherein the plurality of screen assemblies are connected serially by multicables comprising a power cable and a data cable, wherein signal processing elements, data elements, and power supply elements are associated with each emitting element and are housed in a respective control box, and said signal processing and data elements comprising two power sources (PSU) or voltage transformers arranged redundantly, and two image reception cards arranged redundantly in the control box, wherein the two power sources and the two image reception cards are removably and interchangeably housed in the control box;
wherein the separate boxes control one or more of the following:
brightness,
contrast,
image refresh rate,
grey scale,
clock rate;
wherein mechanical and weather resistance requirements for the plurality of control boxes are reduced compared with mechanical and weather resistance requirements for the screen assemblies.
