ABSTRACT:
A large umbrella arrangement includes a stand (2) having a mast (10) to which an extendable and retractable support arm (4) is connected. A connecting member (12) is pivotally connected to the middle area of the support arm (4) and at its other end is pivotally connected to the upper end of the mast (10). One end (26) of the support arm (4) engages the mast (10) by means of a roll (32). This end (26) is further provided with a fork (28) whose arms (30) overlap and receive the mast (10). The support arm (4) is fixable by means of the fork (28) at different height positions on the mast (10), with such fixing in different heights involving the use of an arresting bolt (36) insertable in a bore (34) in the mast (10). At the free end of the support arm (4) is a pin (20) protruding from the support arm from which the umbrella (8) is hung through a hanging means (6).
