Abstract

A support arm arrangement for a local gas extractor arrangement and a local gas extractor arrangement including such a support arm arrangement. The support arm arrangement includes a first support arm and at least one second support arm being pivotally coupled to each other by friction joint arrangements. The support arm arrangement receives a tube device coupled to an extractor hood, an exterior pump device and the support arms. The extractor hood is arranged at an outermost second support arm by a linkage arm arrangement including a first link arm pivotally coupled to the outermost second support arm by a first friction joint pivotable about a first pivoting axis, and a second link arm fixedly attached to the extractor hood and pivotally coupled to the first link arm by a second friction joint pivotable about a second pivoting axis extending in a direction perpendicular to the first pivoting axis.
