Abstract: An umbrella a fixed ring secured on top of a rod, a middle ring and a lower ring slidably engaged on the rod, a number of main staves having inner ends rotatably securing to the middle ring, a number of upper staves pivotally coupled between the fixed ring and the main staves, and a number of stave supports each having an inner end rotatably coupled to the lower ring and an outer end secured to the middle portion of the main staves. The main staves and the stave supports are made of composite materials for increasing the strength and for reducing the weight of the umbrella.

Abstract: An umbrella includes a tube having a lower handle and having an upper whale bone device. A barrel is slidably engaged on the tube and coupled to the whale bone device. A spring-biased catch is received in the tube and selectively engaged into the barrel to lock the barrel to the tube. A latch is slidably received in the barrel for selectively disengaging the catch from the barrel to release the barrel from the tube. The latch is received in the barrel which is moved away from the handle when the whale bone device is opened, such that the latch will not be actuated inadvertently.

Abstract: An umbrella includes a tube having a whale bone device, a barrel slidably engaged on the tube and coupled to the whale bone device. Two spring-biased catches are received in the tube and selectively engaged into the barrel to lock the barrel to the tube and to prevent the barrel from rotating relative to the tube. A latch is slidably received in the barrel for selectively disengaging the catch from the barrel and is received in the barrel which is moved away from the handle when the whale bone device is opened, such that the latch will not be actuated inadvertently.
