Abstract
A telescoping arm has a rod slidable within a sleeve defining an interior bore. A bushing attached to the rod slides within the bore and has a substantially rigid block constrained by the bore against substantial rotation or lateral movement. The bushing further includes a spring portion biased against the sleeve to provide frictional resistance to telescoping of the apparatus and to prevent the bushing from rattling in the bore. The spring responsively accommodates small lateral and rotational forces, while the block bears more substantial loads.
