A foldable, foursided frame, particularly intended for use as a side-wall member in a case (1), as a loading-pallet collar or the like, has two confronting long side walls (2, 3) and two confronting short side walls (4, 5), said long and short walls being hingedly interconnected at the frame corners by means of corner joining members (6-9), such as flexible joining strips. One (2) of the long side walls consists of two juxtaposed wall parts (2', 2"), one (2') of which is hingedly connected to one (4) of the short side walls by means of one (6) of the corner joining members, whereas the other wall part (2") is hingedly connected to the opposite short side wall (5) by means of another one (9) of the corner joining members, said wall parts being hingedly interconnected by means of a supplementary joining member (10), such as a flexible joining strip. Said one (2') wall part has a width equalling that of said one (4) of the short side walls. |
