Abstract

The present invention involves umbrella devices and methods for dual-function umbrellas that may combine a vertical-supported and inclined-suspended umbrella in one structure. A dual-function umbrella that may have vertical supporting and incline suspending structure may have a frame column, umbrella holder and a crank mechanism to position the umbrella holder; the umbrella holder may include a fixed umbrella bracket, moveable umbrella bracket, multiple umbrella ribs with one end pin-jointed to the fixed umbrella bracket, and multiple supporting ribs with opposite ends pin-jointed to the central part of a corresponding umbrella rib and the moveable umbrella bracket. The dual-function umbrella may also have a tilting bar and a cross bar wherein the frame column may be equipped with a moveable locking gear for locking the bottom end of the cross bar. The crank mechanism may be positioned at the cross bar bottom end. Each end of the tilting bar may be pin-jointed to the middle part of the frame column and the lower part of the cross bar respectively. The top end of the cross bar may be pin-jointed to the middle part of the central umbrella rod, and the cross bar may have a slot on the lateral side corresponding to the frame column. Inside the slot there may be an embedded slide block, and the top end of the frame column may be pin-jointed to the slide block, such that the top end of the frame column slide block may move along the slot of and relative to the cross bar.
