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.

Fastening device for a support arm

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.

This invention concerns an arrangementintended to be used in a ventilation arrangement in order to hold and control an air channel. The arrangementcomprises a single arm constructionthat is arranged along the outer surfaceA of the air channel. The arm constructioncomprises two arm sectionsandarranged one after the other, a first jointthat unites a first arm partwith a fixture arrangementthat holds and maintains the basic position of the arm constructionand that makes possible different positioning, bending and stretching, of the arm constructionand the air channel, a second jointthat unites the first arm sectionwith the second arm sectionand that makes possible different positioning, bending and stretching, of the arm constructionand the air channel. Each arm sectionandcomprises an extended aluminum profileand. The invention concerns also a ventilation arrangement comprising such an arrangement

Arrangement and ventilation arrangement

This invention concerns an arrangement () that is comprised as a component () of an airtransport channel where the air-transport channel component () comprises two tubular sub-elements, a first sub-element () and a second sub-element (), where the second element () has a diameter that is somewhat larger than that of the first element (), which allows the first element () to be inserted into the second element () such that the two elements () can be displaced relative to each other in a telescopic manner. The arrangement () is characterised in that it comprises a glide sleeve () that is arranged between the first element () and the second element (), that the glide sleeve () comprises a first part () that retains the glide sleeve () at the second element (), that the glide sleeve () comprises a second part () that makes contact with the first element () under a force (F) that can be adjusted and that is united with the first part (), and that all parts of the second part () are located in front of the first end () of the second element. The invention concerns also a ventilation arm () and a ventilation system ().
