ABSTRACT:
A telescoping support pole suitable for supporting tarpaulins or camouflage netting is described. The pole is made up of a plurality of tubes that nest within one another for storage. To deploy the pole, the tubes are extended in a telescoping fashion. Ball locks are provided for maintaining the extended poles in desired longitudinal relationships. The ball locks are activated by spring loaded collars that force balls into circumferential grooves formed in the outside surfaces of the inner telescoping tubes. The collars may be manually operated to release the ball lock mechanism to permit the pole length to be adjusted or to permit the tubes to be nested within one another for storage. Pivoting fixtures suitable for use at the upper end of the support pole are also described.
