Abstract

A locking mechanism for a telescopically adjustable extension pole (10) is disclosed. The locking mechanism includes a collar member (16) and a locking trigger mechanism preferably comprising a bottom trigger (52) member and a top trigger (54) member having a locking pin (56) therein. The top trigger (54) member grippingly engages the collar member (16) which is attached to the outer sleeve (12) of the pole (10). By depressing the bottom trigger (52) member, the top trigger (54) member moves laterally outwardly retracting the locking pin (56) from an aperture in the inner sleeve (18) permitting the length of the extension pole (10) to be telescopically adjusted. By releasing the bottom trigger (52) member, the top trigger (54) member moves laterally inwardly causing the locking pin (56) to be received within an aperture in the inner sleeve (18) so as to interlock the inner sleeve (18) within the outer sleeve (12) at the approximate desired length of the extension pole (10).
