1. An umbrella comprising:
a fixing tube including first and second ends spaced from each other along a longitudinal axis; a coupling member including a coupling portion and a guiding portion extending along the longitudinal axis and having an upper end, with an axle extending from the upper end of the guiding portion and extending along the longitudinal axis, with the coupling portion of the coupling member fixed to the first end of the fixing tube; a positioning ring mounted around the coupling member, with the positioning ring including an upper end having a fixing toothed portion, and with the positioning ring mounted to and not rotatable relative to the guiding portion of the coupling member; a spring mounted around the guiding portion of the coupling member, with the spring biasing the positioning ring towards the axle; a rotational sleeve rotatably mounted to the axle of the coupling member; a connecting ring fixed to an outer periphery of the rotational sleeve, with the connecting ring including a lower end having a connecting toothed portion, and with the connecting ring and the rotational sleeve jointly rotatable about the longitudinal axis; a driving jacket including a chamber, with the connecting ring received in the chamber, with the positioning ring received in the chamber and rotatable relative to driving jacket, with the driving jacket movable along the longitudinal axis between an engagement position in which the positioning ring engages with the connecting ring and a disengagement position in which the positioning ring disengages from the connecting ring, and with the driving jacket, the connecting ring, and the rotational sleeve jointly rotatable about the longitudinal axis; a movable tube including a lower end located around the rotational sleeve and an upper end located around the driving jacket and spaced from the lower end along the longitudinal axis, with the movable tube and the rotational sleeve jointly rotatable about the longitudinal axis; a canopy operating device including a rotational member fixed to the upper end of the movable tube and a tilt member pivotably connected to the rotational member, with the canopy operating device further including an extension rod having a lower end fixed to the tilt member and an upper end, with the tilt member and the extension rod pivotable relative to the rotational member between an upright position and a tilt position; a rib hub fixed to the upper end of the extension rod; a plurality of ribs, with each of the plurality of ribs having an end pivotably connected to the rib hub; a runner slideably mounted around the canopy operating device and moveable along the canopy operating device between an upper position and a lower position; a plurality of stretchers, with each of the plurality of stretchers including a first end pivotably connected to the runner and a second end pivotably connected to one of the plurality of ribs, wherein with the tilt member in the upright position, the extension rod, the fixing tube, and the movable tube are located on a same straight line, permitting the runner to move between the upper position and the lower position, wherein with the tilt member in the tilt position, the extension rod is tilted relative to the fixing tube and the movable tube, wherein with the runner in the lower position, the tilt member is not permitted to pivot from the upright position to the tilt position, and each of the plurality of stretchers is located adjacent to the extension rod to collapse the plurality of ribs, wherein with the runner in the upper position, the tilt member is permitted to pivot from the upright position to the tilt position, and each of the plurality of stretchers is spaced from the extension rod to stretch open the plurality of ribs, wherein with the driving jacket in the engagement state, the fixing toothed portion of the positioning ring engages with the connecting toothed portion of the connecting ring, avoiding the connecting ring, the rotational sleeve, the driving jacket, and the canopy operating device from pivoting about the longitudinal axis, wherein with the driving jacket in the disengagement state, the fixing toothed portion of the positioning ring disengages from the connecting toothed portion of the connecting ring, permitting the connecting ring, the rotational sleeve, the driving jacket, and the canopy operating device from pivoting about the longitudinal axis, and wherein with the runner in the upper position and with the tilt member in the tilt position, the driving jacket is operable to change an orientation of the rib hub. |
