<p>A push-button operated extendable handle assembly (100) for opening and closing a canopy of an umbrella (200) includes a primary shell member (40) which is movable axially relative to a secondary shell member (10) secured to a handle-side end of a tubular shaft of the umbrella (200), an upper pushing unit (20) disposed to be operated to release a runner (220) from a lowermost position to an uppermost position for opening the canopy, and a lower pushing unit (30) disposed to be operated to release the runner (220) from the uppermost position to the lowermost position for closing the canopy. The primary shell member (40) is actuated through a transmitting mechanism (61) to move between non-stretched and stretched positions when the runner (220) is moved between the lowermost and uppermost positions for facilitating gripping of the handle assembly (100) in a state of use, and for facilitating carrying and storage of the umbrella (200) in a state of non-use.</p> |
