A first plate (3) is pivotally connected via a first edge to a first edge of a second plate (5), the opposing second edge of the second plate being pivotally connected to a first edge of a third plate (7). The second edge of the third plate opposite to its first edge is provided with at least one protruding lip (13) over the length of this plate, for cooperating with at least one groove (15) in the first plate when the holder is unfolded. The plates extend parallel to each other and are located one on top of the other when the holder is collapsed. In the unfolded holder the plates form a triangle. A folding flap (17) is cut from one of the plates, being detached from this plate on three sides and pivotally connected to it on the fourth side. The flap can be folded away to lie in the plane of the plate to which it is attached or it can be unfolded from the plane of this plate in order to support e.g. a laptop computer (19). |
