ABSTRACT:
A mechanism for releasing the slider (4) of an umbrella frame, has a trigger sleeve (8), which cooperates with a locking member (6) of the slider and is axially movable in or on a handle (2) of the umbrella against spring action to move the locking member out of its locking engagement with in the slider. In order to simplify the release for clumsy or ignorant umbrella users or for foolproof operation, there is arranged on the trigger sleeve a secondary trigger which may be pressed radially inwards either manually or upon axial displacement of the trigger to move the locking member out its locking engagement with the slider.
