    Abstract: A fastening device configured to be mounted to an elongated profile element of a support arm arrangement, and a method of mounting said fastening device to a support arm arrangement. The support arm arrangement exhibits a cross-sectional profile shape, and the fastening device is configured to hold a tubing member by means of a holding element, configured to be coupled to the fastening device and to the tubing member. The fastening device includes a contour surface at least partly corresponding with said cross-sectional profile shape, wherein the contour surface is configured for engaging and retaining the fastening device to the elongated profile element when the fastening device is mounted to the elongated profile element.

    Abstract: A lockable friction joint includes a first joint member with a first arm member and a second joint member with a second arm member, the first and second joint members each having an inner friction surface and pivotal connecting projections. A friction adjustment device includes an adjustment element on an outer surface of the second joint member, and a fixating element on an outer surface of the first joint member. A plurality of friction discs are adjacent each other and between the inner friction surfaces of the first and second joint members, whereby friction between the friction discs is adjusted by the adjustment element. Each friction disc has at least one friction surface acting on an adjacent friction surface of another element of the friction joint and each friction disc is pivotally coupled to at least one other element of the friction joint.

    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 of 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 of 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.
