Abstract

A system for accessing internal electrical components of an LED display panel assembly includes a case and a display panel having a plurality of LEDs on an outer surface and electrical components on an inner surface. A linkage assembly is coupled to an inner surface of the case and the inner surface of the display panel and configured for generally translational and generally rotational movement of the display panel from a closed position to an open position for accessing the electrical components.

Claims

1. An access system for a display panel assembly, comprising:

a case;

an LED display panel coupled to a front of the case for movement between a closed position and an open position;

a linkage assembly coupled to an inside surface of the case and an inside surface of the LED display panel, and configured to move the LED display panel in a first generally non-rotational direction and a second generally rotational direction.

2. The system of claim 1 wherein the linkage assembly comprises a first bracket having a slot formed therein and coupled to the inside surface of the case and a second bracket coupled to the LED display panel.

3. The system of claim 2 wherein the linkage assembly further comprises a first link having a first end with a slide member configured for movement within the slot and a second end coupled to the second bracket.

4. The system of claim 3 wherein the linkage assembly further comprises a second link having a first end pivotally coupled to the first bracket and a second end pivotally coupled to a third link and wherein the third link is pivotally coupled to the second bracket.

5. The system of claim 4 wherein at least one of the first link and the second link further comprise a guide member configured to slidably engage a structural portion of the case during movement of the LED display panel between the closed position and the open position.

6. The system of claim 5 wherein the guide member is configured to provide a substantially constant frictional interaction between the linkage assembly and the structural portion of the case as the LED display panel is moved from the closed position to the open position.

7. The system of claim 6 further comprising a spring member configured to provide increasing support to the display panel as the display panel is moved from the closed position to the open position.

8. The system of claim 5 wherein the guide member comprises a wedge shaped portion configured to provide a progressive frictional interaction between the linkage assembly and the structural portion of the case as the LED display panel is moved from the first position to the second position.

9. The system of claim 5 wherein the structural portion of the case is a stile.

10. An access system for an LED display panel assembly, comprising:

an enclosure;

a display configured to cover a front opening of the enclosure and movable between a closed position and an open position to provide access to components installed on at least one of the enclosure and the display panel;

a linkage mechanism coupled to the enclosure and the display panel and configured for generally translational movement of the display panel from the closed position to a partially open position and for generally rotational movement of the display panel from the partially open position to the open position; and

a guide member coupled to the linkage mechanism and configured to at least partially engage a structural component of the enclosure as the display panel is moved between the closed position and the open position.

11. The system of claim 10 wherein the guide member is configured to provide a substantially constant frictional interaction with the structural component of the enclosure.

12. The system of claim 10 wherein the guide member is configured to provide a wedging interaction with the structural component of the enclosure.

13. The system of claim 10 wherein the guide member further comprises a sleeve formed from a material configured to create a frictional interaction with the structural component of the enclosure.

14. The system of claim 10 wherein the guide member is a link member of the linkage mechanism and further comprises a first portion for slidably engaging the structural component of the enclosure and a second portion for interlocking with the structural component of the enclosure to prevent movement of the display panel beyond the open position.

15. The system of claim 10 wherein the open position is within the range of approximately 45-115 degrees.

16. A system for accessing internal electrical components of an LED display panel assembly, comprising:

a case;

a display panel having a plurality of LEDs on an outer surface and electrical components on an inner surface;

a linkage assembly coupled to the case and the display panel and configured for generally translational and generally rotational movement of the display panel from a closed position to an open position for accessing the electrical components.

17. The system of claim 16 wherein the linkage assembly is configured to move the display panel in an outward direction from the closed position to a partially open position to provide clearance with an adjacent display panel.

18. The system of claim 17 wherein the linkage assembly is configured to rotate the display panel from the partially open position to the open position.

19. The system of claim 18 wherein the linkage assembly further comprises a guide member having a first portion configured to slide along a portion of the case as the display panel is moved between the open position and the closed position.

20. The system of claim 19 wherein the guide member further comprises a second portion configured to abut the portion of the case when the display panel reaches the open position.

21. The system of claim 19 wherein the first portion comprises a wedge shaped member configured to engage the portion of the case in a progressive frictional interaction.

22. The system of claim 19 wherein the first portion is configured to engage the portion of the case in a substantially constant frictional interaction.

23. The system of claim 22 further comprising a spring member configured to at least partially support the display panel.

24. The system of claim 16 wherein the linkage assembly includes at least a first link member having a tab configured to interlock with a second link member to at least partially support the display panel in the open position.
