Collapsible security grille, grille system, bar, and method
The invention relates to a collapsible security grille. The grille comprises a multiplicity of successive bars that can be substantially stacked in a retracted state of the grille and can be substantially spaced apart with respect to each other in an extended state of the grille. At least a number of the bars comprises one or multiple parts formed from bent sheet metal. Advantageously, each of at least a number of the bars can be put together from at least a first part formed from a first blank of sheet metal and a second part formed from a second blank of sheet metal. In particular, at least the first part can be a bent profile. Additionally or alternatively, at least the second part can be a bent profile.
