ABSTRACT:
A multicomponent extendible structure which includes three elongated sheets of material which each have two long edge portions and connecting means located on the long edge portions for connecting adjacently located long edge portions together when the adjacently located edge portions are in a substantially nonbent condition and for permitting the long edge portions to be separated when the long edge portions are in a bent condition. The connecting means includes a series of alternating projections and slots located on each long edge portion and the projections on the long edge portion of one elongated sheet of material are adapted to be received by the slots on an adjacently located edge portion of another elongated sheet of material. The long edge portions are readily separable to permit the elongated sheets of material to be separated and stored when the multicomponent extendible structure is in its stored or non-extended condition. Spaced reinforcing members are also provided which are located with their long axis generally perpendicular to the long axis of the elongated sheets of material to give the sheets of material additional strength.
