Abstract: A pocket cage formed from a deformable sheet has a pair of side rings connected by a plurality of webs, each web having a projection comprising a folding of web material formed by bending at a plurality of bending points. At least the material in the middle of each web has reduced resistance to bending relative to the material in areas of each web other than the bending points. This folding is produced by applying opposing pressing forces on the front faces of the side rings using a tool. By placement of the middle bending point on either the outer surface or the bore surface of the web, the projection can be suitably selected to be radially inwardly or outwardly directed respectively.

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).
