An umbrella has a column, an upper nest, a movable lower nest, a plurality of long rods, a plurality of short rods. The upper nest has a plurality of first slots spaced apart on a periphery of the upper nest, a plurality of first pins is disposed on the upper nest respectively; each long rod has a first rod-hanging hook on the top end thereof, each first rod-hanging hook hooks on the corresponding first pin; the lower nest has a plurality of second slots spaced apart on a periphery of the lower nest, a plurality of second pins are disposed on the lower nest respectively; each short rod has a second rod-hanging hook on the bottom end thereof, each second rod-hanging hook hooks on the corresponding second pin. The structure of the present invention is simple and reasonable, the machining is convenient and the cost is low.

The parasol includes a base having a pole, a head secured to one end of the pole and having a canvas filtering at least part of the rays of the sun, and a structure supporting the canvas and being deformable between an open configuration with the canvas outstretched, and a folded configuration with the canvas folded. The support structure includes a hoop or peripheral hoop, which is closed in on itself and lies in a plane in the open configuration. The parasol includes the canvas attached inside the peripheral hoop such that the canvas is stretched out inside the peripheral hoop in the open configuration.

An umbrella includes a shaft, a top cap and a runner. Multiple rib units and multiple stretchers are pivotably connected to the top cap and the runner. The rib units each have a first rib, a second rib and a third rib. The first, second and third ribs are pivotably connected in sequence. A canopy is mounted to the rib units. The second ribs each have a first connection portion on one end thereof, and the first connection portion has a seat which is connected to a link unit. The link unit has a joint which is connected to the third rib. The third rib has a positioning member to position the joint. The third rib and the joint are connected with each other to bear wind force applied to the second rib and the third rib, such that the second and third ribs do not deform.

A cantilever umbrella, including umbrella cloth, an umbrella rod, a top notch with a guide sleeve, a runner, umbrella ribs and stretchers is disclosed. The umbrella rod contains an inner section and a cantilever section; the umbrella rob passes through the guide sleeve and the top notch in sequence with the end of the inner section hinged to the runner. The cantilever section can be extracted from the guide sleeve to open the umbrella ribs and stretch the umbrella cloth into place. The cantilever section can be moved laterally and fixed into position at the end of the guide sleeve to stabilize the open state of the umbrella ribs.
