ABSTRACT:
A telescoping assembly allows the length of an assembly to be readily adjusted. Desirably, the telescoping assembly is used in connection with a table to allow the height of the table to be easily adjusted. The telescoping assembly preferably includes one or more projections formed in telescoping members and the projections provide accurate, low friction contact areas between the telescoping members. Preferably, first and second plurality of projections are provided, and these plurality of projections can be located on either the same telescoping member or different telescoping members. The plurality of projections are preferably evenly distributed about the telescoping members and separated by a given distance, but the projections may be located in any suitable positions and the telescoping assembly can have any appropriate number of projections.
