Slat armour for a door

摘要

The device has a grid (1) comprising a set of bars (1a) parallel to each other, where an end of the set of bars is in the vicinity of a hinge (300) of a hatch (200). Another grid (2) is offset with respect to the hatch. The latter grid comprises a set of bars (2a). The latter grid is positioned with respect to the former grid such that the bars of the latter grid are spatially offset in a plane of the latter grid with respect to the bars of the former grid. The bars of the latter grid pass between the bars of the former grid during pivoting of the hatch.
