<p>A foldable frame for a collapsible explosive entry device the construction of which enables it to be folded into a compact size. The proposed device consists of separate frame elements (18, 20, 22, 24, 26, 28) connected by hinge devices (30, 32, 34, 36, 38, 40) that allow for folding the frame by performing a sequence of operational steps. The sequence includes the successive simultaneous rotation of frame elements (18, 20, 22, 24, 26, 28) around the linking hinge devices (30, 32, 34, 36, 38, 40).</p> |
