Claim:
An umbrella for use in a golf bag for protecting items stored in the golf bag, the umbrella comprising: a telescopic shaft including and upper sliding tube, a lower support tube for slidingly receiving a portion of the upper sliding tube, the lower support tube having a fixed outer diameter, and a ring, the ring having a fixed inner diameter substantially equal to the outer diameter of the lower support tube so as to allow the lower support tube to insert through the ring for fixedly attaching the ring to the lower support tube; and an inverted U-shaped clip fixed to the ring, the clip being capable of fastening to a golf bag; and a canopy frame including an upper hub provided at the top of the sliding tube, a plurality of flexible ribs each having one end pivotably coupled to the upper hub and extended outward therefrom, a plurality of joints each provided at the rib, a lower sliding ring on the sliding tube, and a plurality of stretchers each having one end pivotably coupled to the joint and the other end thereof pivotably coupled to the lower sliding ring, and a canopy disposed over the flexible ribs in order to cover the golf bag when the canopy is fully extended, wherein the sliding tube further comprises an upper collar, and eccentric post having a diameter smaller than that of the sliding tube, a stop extended downward from the collar, and an eccentric C-shaped abutment mechanism sleeved on the eccentric post, the abutment mechanism including an upward protrusion at an open end thereof, wherein the protrusion is substantially opposite to the stop in a first position where the sliding tube is free to slide with respect to the support tube, and about 180 degrees turning of the sliding tube will cause the abutment mechanism to rotate until the protrusion is stopped by the stop at a second position where the outer surface of the abutment mechanisms is urged against the inner surface of the support tube for locking the sliding tube, wherein the abutment mechanism further comprises a thick half circular block, a thin half circular block with the protrusion formed from the open end of the thin half circular block, and a flexible interconnection for coupling the thick and the thin half circular blocks together.
