Abstract:
An elongated pole extendable to substantial heights comprising:(a) a lower end adapted for mounting to a support; (b) a first tubular pole section; (c) a second pole section adapted to nest relative the first pole section between a collapsed position where a substantial amount of the second pole section is nested relative to the first pole section but a portion of the second pole section is above the first pole section and telescopically extend along the longitudinal axis to an extended position where a substantial amount of the second pole section is extended from the first pole section; (d) a releasable locking member mounted on the pole and comprising a component that engages said first and second pole sections when the second pole section is in the extended position to releasably lock the second pole section against longitudinal movement relative the first pole section; (d1) the locking member further comprising a retractable piece mounted on the second pole section and moveable between a retracted position towards the interior of the second pole section and an extended position outwardly of the second pole section; (d2) a biasing member to bias the retractable piece to the extended position; (d3) a receiver on the first pole section, the receiver including an opening adapted to receive the retractable piece when aligned therewith; (d4) a camming surface on the receiver adapted to cam the retractable piece to a retracted position when first and second pole sections are rotated relative to one another.
