Abstract:
A static umbrella with a static mast to which an arm is attached movably in and out by means of a hinge about a tilting axis of the hinge standing perpendicular to the mast axis, in which the arm carries on the mast-remote end a collapsible umbrella, and in which the hinge is provided with an arresting device, by means of which all movements of the hinge are releasable and arrestable, respectively, characterized in that the hinge comprises a togglehead fastenable to the static mast or formed on this, as well as a pair of mirror-symmetrically arranged hinge shells including the togglehead, turnably borne about the tilting axis, in which the hinge shell pair is provided with a longitudinal guide aligned perpendicularly to the tilting axis for the reception of the arm and in which the arresting device comprises a tilting hinge aligned parallel to the tilting axis and a tensioning device, by means of which the hinge shells are pressable against one another and against the togglehead, in such manner that with tightened tensioning device the arm is arrested against traveling in the longitudinal guide and furthermore the hinge shells are arrested against twisting with the togglehead by means of cooperating contact surface pairs, and that with released tensioning device the longitudinal guide of the arm is freeable and, furthermore, the arm is settable in a tilt angle range bounded by end stops between a rest position and a working position.
