Abstract
A lift system removes a display unit or components thereof from a tiled display wall in a way that minimizes the risk of damaging the removed display unit and other display units in the tiled display wall. A lifting structure is configured to selectively lift one or more display units away from the desired display unit when the lifting structure is raised by a vertical motion actuator. The lifting structure is further configured to be free to rotate slightly about a vertical axis when lifting the display units, so that the lifted display units are not constrained to purely vertical translation when lifted away from the desired display unit.
Claims20
A system for removing one or more display units from a multi-display-unit assembly, the system comprising:
- a vertical motion actuator;
- and
- a lift structure coupled to the vertical motion actuator and configured to selectively engage and lift one or more display units when the lift structure is raised by the vertical motion actuator and to rotate a constrained amount about a vertical axis when lifting the one or more display units, wherein each display unit includes:
- a precision frame configured to couple to a vertically adjacent display unit;
- a display surface, and the multi-display-unit assembly is configured to have a substantially uniform gap between each display unit that is less than about 2mm:
- fixed pins positioned on the precision frame;
- and
- a projection assembly having adjustable hangers that are configured to engage the fixed pins and adjust the position of the projection assembly with respect to adjacent projection assemblies of adjacent display units.
A system for removing one or more display units from a multi-display unit assembly, the system comprising:
- a vertical motion actuator;
- and
- a lift structure coupled to the vertical motion actuator and configured to selectively engage and lift one or more display units when the lift structure is raised by the vertical motion actuator and to rotate a constrained amount about a vertical axis when lifting the one or more display units, wherein the lift structure includes:
- a plurality of lifting members arranged along a vertical column, each lifting member having an associated lift position, so that each of the one or more display units is engaged by and lifted with a different lifting member when the lift structure is raised by the vertical motion actuator, wherein the lifting members are organized into subgroups and the lift position associated with each subgroup of lifting members is radially offset on the vertical column from the lift position associated with each of the other subgroups of lifting members.
