ABSTRACT:
A side protection device for scaffoldings, particularly metal scaffoldings including a plurality of substantially vertical tubular posts, each having at least one bracket thereon, traverses attached to the posts, and a boarding resting on the traverses is provided. The side protection device comprises a collapsible framework which is composed of at least one horizontal tubular brace and two substantially vertical tubular side members affixed to the ends of the horizontal tubular brace. The framework can be suspended by means of two supporting arms on two brackets occupying a fixed position on the tubular posts of the scaffolding so that it extends downwards as far or almost as far as the boarding of the scaffolding. The ends of the supporting arms pass, with a certain amount of clearance, through two elongated mounting devices situated on the vertical tubular side members of the framework of the side protection device, in such a way that the side protection device, after being mounted onto the tubular post, will be vertically displaceable by the supporting arms and vertically pivotable, about the supporting arms, towards the relevant section of the scaffolding.
