Abstract: An adjustable gaseous fluid extractor assembly including a first portion and a second portion. The assembly further includes a pivot mechanism providing that the first portion is pivotable relative the second portion about a respective first and second axis. The assembly further includes a flexible tubing element coupled to the first portion and to the second portion. The pivot mechanism is arranged exterior the flexible tubing element.

Abstract: A damper adjusting arrangement configured for regulating the flow of a gaseous fluid within a channel of an extractor tubing. The damper adjusting arrangement includes a damper member pivotably arranged in the channel and coupled to a rotary control means of the damper adjusting arrangement. A first member of the rotary control means includes a resilient element, which exhibits a plurality of radially protruding first bulges being configured for engagement with a second member of the rotary control means.

Abstract: A grounding device for a local gas extractor, a local gas extractor arrangement including such a grounding device, and a method for mounting such a grounding device. The grounding device is configured to interconnect a tubing, a conductive duct and a coupling element of the local gas extractor to divert static electricity. The tubing includes a metal wire, wherein the grounding device includes a conductive body with: a head section configured to interact with a part of the metal wire of the tubing; and a connection section configured to be arranged on the tubing in abutment with the duct and the coupling element.

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 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 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.

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.
