An umbrella includes a shank, a fixed ring mounted on the shank, a movable ring movably mounted on the shank, a plurality of ribs each pivotally and detachably connected with the fixed ring, and a plurality of spreaders each pivotally and detachably connected with the movable ring. Thus, each of the spreaders and the ribs can be removed from the movable ring and the fixed ring respectively for replacement or maintenance, thereby enhancing the lifetime of the umbrella.

Umbrella having a detachable structure

A suspension umbrella includes an upright support post, a sliding seat, a control shaft, an umbrella frame, and a drive cord. The umbrella frame includes a shank, a plurality of ribs, a plurality of spreaders and a runner. Thus, the umbrella frame is expanded when the control shaft is movable toward the umbrella frame and is folded when the control shaft is movable outwardly relative to the umbrella frame, so that the umbrella frame is expanded and folded easily and conveniently. In addition, the user only needs to operate the control handle to move the control shaft so as to expand or fold the umbrella frame easily and quickly, thereby greatly facilitating the user operating the suspension umbrella.
