A collapsible support structure for a cover means (8). The structure includes at least three apex poles (1) with first ends pivotally connected together (2) so that in use the poles are movable between a raised configuration in which the opposite ends (7) of the apex poles extend outwardly to create a pyramid shaped frame and a collapsed configuration. There are pairs of perimeter poles (6) with each pair forming an inverted V between the opposite ends of adjacent apex poles when in the raised position.
