TELESCOPIC SUPPORT FOR AN EXPANDABLE SHELTER SYSTEM

摘要

A telescopic support assembly including tube assemblies and bearing assemblies. The tube assemblies are arranged telescopically from a largest cross section rear tube assembly to a smallest cross section front tube assembly. The bearing assemblies include a non-roller bearing for each tube assembly other than the front tube assembly. Each bearing assembly is configured to present a surface of the non-roller bearing at the bottom interior of a tube assembly, proximate the front of the tube. Some embodiments include a drive assembly for extending and retracting the telescopic support assembly.
