A collapsible support frame F, specifically designed for the support of an open-topped litter sack S, comprises two frame members 1 and 2 which are interlinked for generally scissor-like articulatory movement between collapsed and erected conditions of the frame F. The interlinking of the members 1 and 2 is provided, at each side of the frame F, by interengaged loop formations 4 and 6 of the frame members 1 and 2. The interengagement of the loops 4 and 6 defines the axis of said articulatory movement and limits relative opening movement of the frame members 1 and 2 to define the erected condition of the frame F. For assembling the pre-formed frame members 1 and 2 together, the member 1 is of smaller dimensions than the other so that it can be passed through the member 2 during assembly of the frame F. <IMAGE> |
