Umbrella operatively closed by directly pulling runner downwardly along a guiding sleeve

An umbrella comprising:

• a central shaft defining a longitudinal axis in said shaft;
• and
• a rib assembly pivotally secured to the central shaft and pivotally secured to a runner;
• said central shaft having a guiding sleeve secured to an upper notch on a top of said shaft and disposed around said central shaft for slidably engaging said runner on said sleeve;
• said guiding sleeve having a resilient protrusion formed on said sleeve;
• said runner having a socket recessed in said runner and a sloping portion inclined upwardly from said socket towards said longitudinal axis in said shaft;
• whereby upon engagement of said resilient protrusion on said sleeve with said socket in said runner, said runner will be stably engaged on said guiding sleeve for opening the umbrella;
• and upon downward pulling of said runner to allow said sloping portion in said runner to thrust said resilient protrusion inwardly towards said axis to disengage said socket of said runner from said protrusion on said sleeve, said runner will be lowered for closing the umbrella.
