1. An umbrella assembly comprising:
- a support pole assembly, comprising;
a supporting pole having a lower end and an upper end;
a holding sleeve coupled with the upper end of the supporting pole, the holding sleeve including a first end and a second end;
a suspending tube extending through the holding sleeve and having a first end, a second end, and a longitudinal axis; and
a canopy assembly coupled with the second end of the suspending tube for suspending a canopy fabric; and
a tilting device comprising;
a worm gear coupled with a shaft rotatably journaled on the support pole assembly and configured to be driven by a crank member; and
a plurality of gear teeth coupled with an outer surface of the suspending tube adjacent the first end thereofwherein the gear teeth are engaged by the worm gear such that rotation of the worm gear causes the suspending tube to rotate about said longitudinal axis.

Abstract
An umbrella is provided that includes a support pole, at least a portion of which extends upwardly in use, a suspending pole, a canopy, and a mechanism for rotating the suspending pole about its longitudinal axis. The suspending pole is mounted transversely to the support pole and has first and second ends and a longitudinal axis. The canopy is suspended in use from the second end of the support pole. The mechanism includes a plurality of gear teeth coupled with the suspending pole to cause the suspending pole to rotate in either direction about said axis upon movement of the gear teeth and to thereby cause the canopy to tilt in either direction about said axis.

15. An umbrella assembly comprising:
-
a support pole having a lower end and an upper end; a suspending tube having first and second ends and a longitudinal axis and being coupled with the support pole, the suspending tube being movable relative to the support pole between an extended position and a retracted position, wherein the second end is farther from the support pole in the extended position than in the retracted position; and a canopy assembly coupled with the second end of the suspending tube for suspending a canopy fabric; a first mechanism for rotating the suspending tube about its longitudinal axis, comprising a driven member coupled with an external surface of the suspending tube, the first mechanism configured to transmit a force to the driven member to cause the suspending tube to rotate in either direction about said axis upon movement of the driven member and to thereby cause the canopy to tilt in either direction about said axis; and a second mechanism permitting retraction and extension of the suspending tube relative to the support pole, the second mechanism comprising a gripping member configured to apply sufficient force to an external surface of the suspending tube to fix the position of the suspending tube relative to the support tube. - View Dependent Claims (16, 17)

18. An umbrella comprising:
-
a support pole, at least a portion of which extends upwardly in use; a suspending pole, mounted transversely to the support pole and having first and second ends and a longitudinal axis; a canopy suspended in use from the second end of the suspending pole; a mechanism for rotating the suspending pole about its longitudinal axis, comprising a ring gear comprising a plurality of gear teeth mounted on an external surface of the suspending pole, the mechanism configured to cause the suspending pole to rotate in either direction about said axis upon movement of the gear teeth and to thereby cause the canopy to tilt in either direction about said axis; wherein the mechanism for rotating further comprises a worm gear configured to be driven by a crank handle, the worm gear journaled for rotation and being mounted in relation to the ring gear to drive the ring gear when the worm gear is driven by the crank handle. - View Dependent Claims (19, 20)

21. An umbrella comprising:
-
a support pole, at least a portion of which extends upwardly in use; a suspending pole, mounted transversely to the support pole and having first and second ends and a longitudinal axis; a canopy suspended in use from the second end of the suspending pole; a mechanism for rotating the suspending pole about its longitudinal axis, comprising a plurality of gear teeth coupled with the suspending pole to cause the suspending pole to rotate in either direction about said axis upon movement of the gear teeth and to thereby cause the canopy to tilt in either direction about said axis; a locking device having a first configuration preventing movement of the suspending pole relative to the support pole and a second configuration permitting movement of the suspending pole relative to the support pole; and a limiter device coupled with the suspending pole to limit the movement of the ring relative to the suspending pole.

22. An umbrella comprising:
-
a support pole, at least a portion of which extends upwardly in use; a suspending pole, mounted transversely to the support pole and having first and second ends and a longitudinal axis; a canopy suspended in use from the second end of the suspending pole; and a mechanism for rotating the suspending pole about its longitudinal axis, comprising a plurality of gear teeth coupled with the suspending pole to cause the suspending pole to rotate in either direction about said axis upon movement of the gear teeth and to thereby cause the canopy to tilt in either direction about said axis; wherein said canopy comprises a rib assembly comprising a plurality of ribs extending from a central shaft, a natural or synthetic material extended over the ribs, said ribs being movable along said shaft to open and close the canopy, said umbrella further comprising a mechanism for opening and closing a canopy, said mechanism comprising; a drum, rotatable by a crank; a cable wound on said drum and extending inside the suspending pole generally along its longitudinal axis to such rib assembly, so that winding or unwinding said cable causes the rib assembly to move up or down said shaft. - View Dependent Claims (23)
