ABSTRACT:
An extendable surface comprising a plurality of triangular leaves is disclosed. The leaves are arranged one above another and are hingedly mounted at the apex of each leaf for rotational motion between a retracted position in which the leaves are arranged in overlapping relation, to an extended position in which the leaves are adjacent to one another. The leaves have interengaging hooks along their edges which link the leaves together in the extended position and seal the surface, preventing water from leaking through the surface.
