ABSTRACT:
A lock mechanism mounted in a large umbrella includes a sliding sleeve including an aperture on surface of a lower extension, a telescopic shank including a lower tube fixed in a handle and a sliding upper tube, a lock device disposed in the upper tube such that disposing a resilient projection of the lock device through holes of the tubes may fasten the shank, an actuation assembly for receiving the extension and including a transverse opening and a spring biased actuation member having a portion disposed in the aperture for locking the extension in a closed position of the umbrella, the actuation member including a trigger, and a spring biased rib fixing assembly disposed between the handle and the actuation assembly. Pushing the trigger will disengage the portion with the aperture to open the umbrella. Operating the lock device will effect a subsequent multi-sectional length adjustment of the shank.
