Collapsible support structure
A collapsible support structure comprises a first hollow pole 4 and a second hollow pole 6 connected by a resilient flexible cord 8, e.g. an elastomer cord. The first hollow pole has an open end 10 through which the resilient cord passes. The perimeter of the open end comprises a leading portion and a trailing portion, the leading portion extending further than the trailing portion. The second hollow pole is connected to the first hollow pole by the resilient cord and is adapted to engage the open end when the support structure is assembled. By providing a leading portion and a trailing portion, the tension on the resilient cord is reduced when the poles are folded in the collapsed condition and the possibility of cord breakage when the poles are dropped on an end when folded is reduced as the leading end strikes the ground rather than the cord. The collapsible support structure may be for a tent, net (Fig. 7) or display screen.
